145-536: The Nuclear Energy Institute ( NEI ) is a nuclear industry trade association in the United States, based in Washington, D.C. The Nuclear Energy Institute represents the nuclear technologies industry. NEI’s stated mission “is to promote the use and growth of nuclear energy through efficient operations and effective policy.” NEI works on legislative and regulatory issues impacting the industry, such as
290-478: A federal structure with two overlapping power centers so that each citizen as an individual is subject to the powers of state government and national government. To protect against abuse of power, each branch of government – executive, legislative, and judicial – had a separate sphere of authority and could check other branches according to the principle of the separation of powers . Furthermore, there were checks and balances within
435-403: A neutron hits the nucleus of a uranium-235 or plutonium atom, it can split the nucleus into two smaller nuclei, which is a nuclear fission reaction. The reaction releases energy and neutrons. The released neutrons can hit other uranium or plutonium nuclei, causing new fission reactions, which release more energy and more neutrons. This is called a chain reaction . In most commercial reactors,
580-496: A nuclear renaissance , an increase in the construction of new reactors, due to concerns about carbon dioxide emissions . During this period, newer generation III reactors , such as the EPR began construction. Prospects of a nuclear renaissance were delayed by another nuclear accident. The 2011 Fukushima Daiichi nuclear accident was caused by the Tōhoku earthquake and tsunami , one of
725-592: A "driving force in American government" and a "remarkably resilient institution". Congress is the "heart and soul of our democracy", according to this view, even though legislators rarely achieve the prestige or name recognition of presidents or Supreme Court justices ; one wrote that "legislators remain ghosts in America's historical imagination." One analyst argues that it is not a solely reactive institution but has played an active role in shaping government policy and
870-472: A Senate and House of Representatives." The House and Senate are equal partners in the legislative process – legislation cannot be enacted without the consent of both chambers. The Constitution grants each chamber some unique powers. The Senate ratifies treaties and approves presidential appointments while the House initiates revenue -raising bills. The House initiates impeachment cases, while
1015-674: A country is leading in nuclear energy development, it would also be leading in the world. Nuclear power plants would be able to function even if something were to happen to the electrical grid around them which would greatly help the US. The sustainable development of increasing our nuclear energy would be very beneficial. NEI claims that it could even help poverty, hunger, and stagnant economies. Nuclear energy would help because it would provide individuals with clean, low-cost, secure energy. Infrastructure within America has not been able to keep pace with Americans rapidly increasing power needs. To keep
1160-520: A less efficient plant that utilizes fossil fuels. This could hurt up to one-quarter of the environmental benefits that these nuclear plants have contributed. Along with the advocacy of policy, NEI also is dedicated to advocating the advantages of nuclear energy as well. Some of the main advantages that NEI states are the benefits in climate, national security, sustainable development, infrastructure, and air quality. Nuclear energy will help our climate by contributing to decarbonization. NEI also argues that if
1305-410: A low-level waste disposal site. In countries with nuclear power, radioactive wastes account for less than 1% of total industrial toxic wastes, much of which remains hazardous for long periods. Overall, nuclear power produces far less waste material by volume than fossil-fuel based power plants. Coal-burning plants, in particular, produce large amounts of toxic and mildly radioactive ash resulting from
1450-581: A non-technical audience, the agency provides assistance if requested, a common industry practice. In 1999, Public Citizen filed a complaint with the Federal Trade Commission charging that an NEI advertising campaign overstated the environmental benefits of nuclear energy to consumers living in markets where sales of electricity had been deregulated. In a ruling the following December, the FTC rejected those claims concluding: NEI did not violate
1595-444: A powerful effect of waking up a somewhat dormant Congress which investigated presidential wrongdoing and coverups; the scandal "substantially reshaped" relations between the branches of government, suggested political scientist Bruce J. Schulman . Partisanship returned, particularly after 1994; one analyst attributes partisan infighting to slim congressional majorities which discouraged friendly social gatherings in meeting rooms such as
SECTION 10
#17327808281461740-533: A reactor. Spent thorium fuel, although more difficult to handle than spent uranium fuel, may present somewhat lower proliferation risks. The nuclear industry also produces a large volume of low-level waste , with low radioactivity, in the form of contaminated items like clothing, hand tools, water purifier resins, and (upon decommissioning) the materials of which the reactor itself is built. Low-level waste can be stored on-site until radiation levels are low enough to be disposed of as ordinary waste, or it can be sent to
1885-524: A revised constitution with a two-chamber or bicameral Congress. Smaller states argued for equal representation for each state. The two-chamber structure had functioned well in state governments. A compromise plan, the Connecticut Compromise , was adopted with representatives chosen by population (benefiting larger states) and exactly two senators chosen by state governments (benefiting smaller states). The ratified constitution created
2030-1087: A shortage near the end of the century. A 2017 study by researchers from MIT and WHOI found that "at the current consumption rate, global conventional reserves of terrestrial uranium (approximately 7.6 million tonnes) could be depleted in a little over a century". Limited uranium-235 supply may inhibit substantial expansion with the current nuclear technology. While various ways to reduce dependence on such resources are being explored, new nuclear technologies are considered to not be available in time for climate change mitigation purposes or competition with alternatives of renewables in addition to being more expensive and require costly research and development. A study found it to be uncertain whether identified resources will be developed quickly enough to provide uninterrupted fuel supply to expanded nuclear facilities and various forms of mining may be challenged by ecological barriers, costs, and land requirements. Researchers also report considerable import dependence of nuclear energy. Unconventional uranium resources also exist. Uranium
2175-405: A significant effect on countries, such as France and Japan , which had relied more heavily on oil for electric generation to invest in nuclear power. France would construct 25 nuclear power plants over the next 15 years, and as of 2019, 71% of French electricity was generated by nuclear power, the highest percentage by any nation in the world. Some local opposition to nuclear power emerged in
2320-582: A state's at-large representation to the federal government by senators. Most incumbents seek re-election, and their historical likelihood of winning subsequent elections exceeds 90 percent. The historical records of the House of Representatives and the Senate are maintained by the Center for Legislative Archives, which is a part of the National Archives and Records Administration . Congress
2465-610: A tie. The House of Representatives has six non-voting members . Congress convenes for a two-year term , commencing every other January. Elections are held every even-numbered year on Election Day . The members of the House of Representatives are elected for the two-year term of a Congress. The Reapportionment Act of 1929 established that there be 435 representatives, and the Uniform Congressional Redistricting Act requires that they be elected from single-member constituencies or districts . It
2610-425: A typical nuclear power station are often stored on site in dry cask storage vessels. Presently, waste is mainly stored at individual reactor sites and there are over 430 locations around the world where radioactive material continues to accumulate. Disposal of nuclear waste is often considered the most politically divisive aspect in the lifecycle of a nuclear power facility. The lack of movement of nuclear waste in
2755-490: Is high-level radioactive waste . While its radioactivity decreases exponentially, it must be isolated from the biosphere for hundreds of thousands of years, though newer technologies (like fast reactors ) have the potential to significantly reduce this. Because the spent fuel is still mostly fissionable material, some countries (e.g. France and Russia ) reprocess their spent fuel by extracting fissile and fertile elements for fabrication into new fuel, although this process
2900-408: Is spent nuclear fuel , which is considered high-level waste . For Light Water Reactors (LWRs), spent fuel is typically composed of 95% uranium, 4% fission products , and about 1% transuranic actinides (mostly plutonium , neptunium and americium ). The fission products are responsible for the bulk of the short-term radioactivity, whereas the plutonium and other transuranics are responsible for
3045-725: Is 89%. Most new reactors under construction are generation III reactors in Asia. Proponents contend that nuclear power is a safe, sustainable energy source that reduces carbon emissions . This is because nuclear power generation causes one of the lowest levels of fatalities per unit of energy generated compared to other energy sources. Coal, petroleum, natural gas and hydroelectricity have each caused more fatalities per unit of energy due to air pollution and accidents . Nuclear power plants also emit no greenhouse gases and result in less life-cycle carbon emissions than common "renewables". The radiological hazards associated with nuclear power are
SECTION 20
#17327808281463190-486: Is a fairly common element in the Earth's crust: it is approximately as common as tin or germanium , and is about 40 times more common than silver . Uranium is present in trace concentrations in most rocks, dirt, and ocean water, but is generally economically extracted only where it is present in relatively high concentrations. Uranium mining can be underground, open-pit , or in-situ leach mining. An increasing number of
3335-461: Is also produced during plant decommissioning. There are two broad categories of nuclear waste: low-level waste and high-level waste. The first has low radioactivity and includes contaminated items such as clothing, which poses limited threat. High-level waste is mainly the spent fuel from nuclear reactors, which is very radioactive and must be cooled and then safely disposed of or reprocessed. The most important waste stream from nuclear power reactors
3480-497: Is also required that the congressional districts be apportioned among states by population every ten years using the U.S. census results, provided that each state has at least one congressional representative. Each senator is elected at-large in their state for a six-year term, with terms staggered , so every two years approximately one-third of the Senate is up for election. Each state, regardless of population or size, has two senators, so currently, there are 100 senators for
3625-489: Is also safer in terms of nuclear proliferation potential. Reprocessing has the potential to recover up to 95% of the uranium and plutonium fuel in spent nuclear fuel, as well as reduce long-term radioactivity within the remaining waste. However, reprocessing has been politically controversial because of the potential for nuclear proliferation and varied perceptions of increasing the vulnerability to nuclear terrorism . Reprocessing also leads to higher fuel cost compared to
3770-476: Is another point that is used to guide policies. Its goal is to sustain the operations of the existing plants through more efficient practices and smarter regulations. The point of innovation emphasizes creating newer nuclear technologies that will produce greener energy. Lastly, thrive touches on the point of saying that it is essential to our country's leadership that we can do well in the global nuclear energy marketplace. One of these most important, pressing points
3915-498: Is considered the worst nuclear disaster in history both in total casualties, with 56 direct deaths, and financially, with the cleanup and the cost estimated at 18 billion Rbls (US$ 68 billion in 2019, adjusted for inflation). The international organization to promote safety awareness and the professional development of operators in nuclear facilities, the World Association of Nuclear Operators (WANO),
4060-410: Is contained within sixteen casks. It is estimated that to produce a lifetime supply of energy for a person at a western standard of living (approximately 3 GWh ) would require on the order of the volume of a soda can of low enriched uranium , resulting in a similar volume of spent fuel generated. Following interim storage in a spent fuel pool , the bundles of used fuel rod assemblies of
4205-558: Is currently done in France, the United Kingdom, Russia, Japan, and India. In the United States, spent nuclear fuel is currently not reprocessed. The La Hague reprocessing facility in France has operated commercially since 1976 and is responsible for half the world's reprocessing as of 2010. It produces MOX fuel from spent fuel derived from several countries. More than 32,000 tonnes of spent fuel had been reprocessed as of 2015, with
4350-693: Is directly responsible for the governing of the District of Columbia , the current seat of the federal government. The First Continental Congress was a gathering of representatives from twelve of the Thirteen Colonies . On July 4, 1776, the Second Continental Congress adopted the Declaration of Independence , referring to the new nation as the "United States of America". The Articles of Confederation in 1781 created
4495-440: Is elected and gives each House the power to create its own structure. Section Seven lays out the process for creating laws, and Section Eight enumerates numerous powers. Section Nine is a list of powers Congress does not have, and Section Ten enumerates powers of the state, some of which may only be granted by Congress. Constitutional amendments have granted Congress additional powers. Congress also has implied powers derived from

4640-493: Is essentially charged with reconciling our many points of view on the great public policy issues of the day. Congress is constantly changing and is constantly in flux. In recent times, the American South and West have gained House seats according to demographic changes recorded by the census and includes more women and minorities . While power balances among the different parts of government continue to change,
4785-433: Is extraordinarily sensitive to public pressure. Several academics described Congress: Congress reflects us in all our strengths and all our weaknesses. It reflects our regional idiosyncrasies, our ethnic, religious, and racial diversity, our multitude of professions, and our shadings of opinion on everything from the value of war to the war over values. Congress is the government's most representative body ... Congress
4930-454: Is governed by a 47-member board of directors. The board includes representatives from the nation's 27 nuclear utilities, plant designers, architect/engineering firms and fuel cycle companies. Eighteen members of the board serve on the executive committee, which is responsible for NEI's business and policy affairs. It has been charged with blatant misrepresentations in the CEO advertising campaign by
5075-405: Is in the commissioning phase, with plans to build more. Another alternative to fast-neutron breeders are thermal-neutron breeder reactors that use uranium-233 bred from thorium as fission fuel in the thorium fuel cycle . Thorium is about 3.5 times more common than uranium in the Earth's crust, and has different geographic characteristics. India's three-stage nuclear power programme features
5220-424: Is more expensive than producing new fuel from mined uranium . All reactors breed some plutonium-239 , which is found in the spent fuel, and because Pu-239 is the preferred material for nuclear weapons , reprocessing is seen as a weapon proliferation risk. The first nuclear power plant was built in the 1950s. The global installed nuclear capacity grew to 100 GW in the late 1970s, and then expanded during
5365-521: Is much less radioactive than spent nuclear fuel by weight, coal ash is produced in much higher quantities per unit of energy generated. It is also released directly into the environment as fly ash , whereas nuclear plants use shielding to protect the environment from radioactive materials. Nuclear waste volume is small compared to the energy produced. For example, at Yankee Rowe Nuclear Power Station , which generated 44 billion kilowatt hours of electricity when in service, its complete spent fuel inventory
5510-478: Is naturally present in seawater at a concentration of about 3 micrograms per liter, with 4.4 billion tons of uranium considered present in seawater at any time. In 2014 it was suggested that it would be economically competitive to produce nuclear fuel from seawater if the process was implemented at large scale. Like fossil fuels, over geological timescales, uranium extracted on an industrial scale from seawater would be replenished by both river erosion of rocks and
5655-617: Is the reactor-grade plutonium (RGPu) that is extracted from spent fuel. It is mixed with uranium oxide and fabricated into mixed-oxide or MOX fuel . Because thermal LWRs remain the most common reactor worldwide, this type of recycling is the most common. It is considered to increase the sustainability of the nuclear fuel cycle, reduce the attractiveness of spent fuel to theft, and lower the volume of high level nuclear waste. Spent MOX fuel cannot generally be recycled for use in thermal-neutron reactors. This issue does not affect fast-neutron reactors , which are therefore preferred in order to achieve
5800-693: Is the preservation of nuclear power plants. In the next few years, about half of the operating licenses for the US’s nuclear plants will expire However, the NEI is helping provide information and push policy to help increase the amount of Second License Renewals. Second license renewal is where a nuclear power plant can extend its original operating license for up to 20 years. This is important because if these plants are forced to close if they do not renew their license, then they will most likely not be replaced with another nuclear power plant. They will probably be replaced with
5945-458: Is then converted into a compact ore concentrate form, known as yellowcake (U 3 O 8 ), to facilitate transport. Fission reactors generally need uranium-235 , a fissile isotope of uranium . The concentration of uranium-235 in natural uranium is low (about 0.7%). Some reactors can use this natural uranium as fuel, depending on their neutron economy . These reactors generally have graphite or heavy water moderators. For light water reactors,

6090-529: The tabloidization of media coverage. Others saw pressure to squeeze a political position into a thirty-second soundbite. A report characterized Congress in 2013 as unproductive, gridlocked, and "setting records for futility". In October 2013, with Congress unable to compromise, the government was shut down for several weeks and risked a serious default on debt payments, causing 60% of the public to say they would "fire every member of Congress" including their own representative. One report suggested Congress posed
6235-544: The Board of Education . Congress began reasserting its authority. Lobbying became a big factor despite the 1971 Federal Election Campaign Act . Political action committees or PACs could make substantive donations to congressional candidates via such means as soft money contributions. While soft money funds were not given to specific campaigns for candidates, the money often benefited candidates substantially in an indirect way and helped reelect candidates. Reforms such as
6380-541: The Commerce Clause , the enumerated power to regulate commerce, in rulings such as McCulloch v. Maryland , have effectively widened the scope of Congress's legislative authority far beyond that prescribed in Section Eight. Constitutional responsibility for the oversight of Washington, D.C. , the federal district and national capital, and the U.S. territories of Guam , American Samoa , Puerto Rico ,
6525-587: The Congress of the Confederation , a unicameral body with equal representation among the states in which each state had a veto over most decisions. Congress had executive but not legislative authority, and the federal judiciary was confined to admiralty and lacked authority to collect taxes, regulate commerce, or enforce laws. Government powerlessness led to the Convention of 1787 which proposed
6670-609: The Conservative Coalition . Democrats maintained control of Congress during World War II . Congress struggled with efficiency in the postwar era partly by reducing the number of standing congressional committees. Southern Democrats became a powerful force in many influential committees although political power alternated between Republicans and Democrats during these years. More complex issues required greater specialization and expertise, such as space flight and atomic energy policy. Senator Joseph McCarthy exploited
6815-523: The Northern Mariana Islands . These six members of Congress enjoy floor privileges to introduce bills and resolutions, and in recent Congresses they vote in permanent and select committees, in party caucuses and in joint conferences with the Senate. They have Capitol Hill offices, staff and two annual appointments to each of the four military academies. While their votes are constitutional when Congress authorizes their House Committee of
6960-540: The Onkalo spent nuclear fuel repository of the Olkiluoto Nuclear Power Plant was under construction as of 2015. Most thermal-neutron reactors run on a once-through nuclear fuel cycle , mainly due to the low price of fresh uranium. However, many reactors are also fueled with recycled fissionable materials that remain in spent nuclear fuel. The most common fissionable material that is recycled
7105-542: The United States Senate . It meets in the United States Capitol in Washington, D.C. Members are chosen through direct election , though vacancies in the Senate may be filled by a governor 's appointment. Congress has 535 voting members: 100 senators and 435 representatives. The vice president of the United States , as President of the Senate, has a vote in the Senate only when there is
7250-680: The White House , Nuclear Regulatory Commission , departments of Commerce, Defense, Energy and others in the first three months of the year. The NEI spent $ 1.3 million to lobby the federal government in 2007. In 2012, NEI quoted Kathyrn Higley, professor of radiation health physics in the department of nuclear engineering at Oregon State University, who described the health impact of the Fukushima Daiichi nuclear accident to be "really, really minor", adding that "the Japanese government
7395-439: The integral fast reactor and molten salt reactors , can use as fuel the plutonium and other actinides in spent fuel from light water reactors, thanks to their fast fission spectrum. This offers a potentially more attractive alternative to deep geological disposal. The thorium fuel cycle results in similar fission products, though creates a much smaller proportion of transuranic elements from neutron capture events within

Watershed political moments like the confirmation of Clarence Thomas and the 2016 presidential election created momentum for women candidates, resulting in the Year of
7685-422: The thermal energy released from nuclear fission . A fission nuclear power plant is generally composed of: a nuclear reactor , in which the nuclear reactions generating heat take place; a cooling system, which removes the heat from inside the reactor; a steam turbine , which transforms the heat into mechanical energy ; an electric generator , which transforms the mechanical energy into electrical energy. When

There has been increasing public dissatisfaction with Congress, with extremely low approval ratings which dropped to 5% in October 2013. In 2009, Congress authorized another delegate for
7975-439: The 1960s opened the possibility for Black, Asian American, Latina and other non-white women candidates to run for Congress. Racially polarized voting, racial stereotypes and lack of institutional support still prevent women of color from reaching Congress as easily as white people . Senate elections, which require victories in statewide electorates, have been particularly difficult for women of color. Carol Moseley Braun became

The 1979 Three Mile Island accident in the United States and the 1986 Chernobyl disaster in the Soviet Union resulted in increased regulation and public opposition to nuclear power plants. These factors, along with high cost of construction, resulted in the global installed capacity only increasing to 392 GW by 2023. These plants supplied 2,602 terawatt hours (TWh) of electricity in 2023, equivalent to about 9% of global electricity generation , and were
8265-766: The 2 billion year old natural nuclear fission reactors in Oklo , Gabon is cited as "a source of essential information today." Experts suggest that centralized underground repositories which are well-managed, guarded, and monitored, would be a vast improvement. There is an "international consensus on the advisability of storing nuclear waste in deep geological repositories ". With the advent of new technologies, other methods including horizontal drillhole disposal into geologically inactive areas have been proposed. There are no commercial scale purpose built underground high-level waste repositories in operation. However, in Finland
8410-846: The 2002 Bipartisan Campaign Reform Act limited campaign donations but did not limit soft money contributions. One source suggests post-Watergate laws amended in 1974 meant to reduce the "influence of wealthy contributors and end payoffs" instead "legitimized PACs" since they "enabled individuals to band together in support of candidates". From 1974 to 1984, PACs grew from 608 to 3,803 and donations leaped from $ 12.5 million to $ 120 million along with concern over PAC influence in Congress. In 2009, there were 4,600 business, labor and special-interest PACs including ones for lawyers , electricians , and real estate brokers . From 2007 to 2008, 175 members of Congress received "half or more of their campaign cash" from PACs. From 1970 to 2009,

These anti-nuclear concerns related to nuclear accidents , nuclear proliferation , nuclear terrorism and radioactive waste disposal . In the early 1970s, there were large protests about a proposed nuclear power plant in Wyhl , Germany. The project was cancelled in 1975. The anti-nuclear success at Wyhl inspired opposition to nuclear power in other parts of Europe and North America. By

Due to the lack of emissions from nuclear energy, it acts as a beneficial option for states attempting to comply with the Clean Air Act. Nuclear industry Nuclear power is the use of nuclear reactions to produce electricity . Nuclear power can be obtained from nuclear fission , nuclear decay and nuclear fusion reactions. Presently,
10875-401: The United States, over 120 Light Water Reactor proposals were ultimately cancelled and the construction of new reactors ground to a halt. The 1979 accident at Three Mile Island with no fatalities, played a major part in the reduction in the number of new plant constructions in many countries. During the 1980s one new nuclear reactor started up every 17 days on average. By the end of
11020-554: The White House a little more in favor of the executive branch", according to one account. Past presidents, including Ronald Reagan , George H. W. Bush , Bill Clinton , and George W. Bush , have made public statements when signing congressional legislation about how they understand a bill or plan to execute it, and commentators, including the American Bar Association , have described this practice as against
11165-504: The Whole votes, recent Congresses have not allowed for that, and they cannot vote when the House is meeting as the House of Representatives. On January 6, 2021, the Congress gathered to confirm the election of Joe Biden, when supporters of the outgoing president Donald Trump attacked the building . The session of Congress ended prematurely, and Congress representatives evacuated. Trump supporters occupied Congress until D.C police evacuated
11310-552: The Woman and the election of members of The Squad , respectively. Women of color faced additional challenges that made their ascension to Congress even more difficult. Jim Crow laws , voter suppression and other forms of structural racism made it virtually impossible for women of color to reach Congress prior to 1965. The passage of the Voting Rights Act that year , and the elimination of race-based immigration laws in
11455-640: The actinides (the most active and dangerous components) in the present inventory of nuclear waste, while also producing power and creating additional quantities of fuel for more reactors via the breeding process. As of 2017, there are two breeders producing commercial power, BN-600 reactor and the BN-800 reactor , both in Russia. The Phénix breeder reactor in France was powered down in 2009 after 36 years of operation. Both China and India are building breeder reactors. The Indian 500 MWe Prototype Fast Breeder Reactor
11600-662: The area. The event was the first time since the Burning of Washington by the British during the War of 1812 that the United States Congress was forcefully occupied. Various social and structural barriers have prevented women from gaining seats in Congress. In the early 20th century, women's domestic roles and the inability to vote forestalled opportunities to run for and hold public office. The two party system and
11745-417: The budget has been lost when the welfare state expanded since "entitlements were institutionally detached from Congress's ordinary legislative routine and rhythm." Another factor leading to less control over the budget was a Keynesian belief that balanced budgets were unnecessary. The Sixteenth Amendment in 1913 extended congressional power of taxation to include income taxes without apportionment among
11890-593: The building of larger single-purpose production reactors for the production of weapons-grade plutonium for use in the first nuclear weapons. The United States tested the first nuclear weapon in July 1945, the Trinity test , and the atomic bombings of Hiroshima and Nagasaki happened one month later. Despite the military nature of the first nuclear devices, there was strong optimism in the 1940s and 1950s that nuclear power could provide cheap and endless energy. Electricity
12035-702: The bulk of the long-term radioactivity. High-level waste (HLW) must be stored isolated from the biosphere with sufficient shielding so as to limit radiation exposure. After being removed from the reactors, used fuel bundles are stored for six to ten years in spent fuel pools , which provide cooling and shielding against radiation. After that, the fuel is cool enough that it can be safely transferred to dry cask storage . The radioactivity decreases exponentially with time, such that it will have decreased by 99.5% after 100 years. The more intensely radioactive short-lived fission products (SLFPs) decay into stable elements in approximately 300 years, and after about 100,000 years,
12180-416: The case of the latter, the lack of affiliation with a political party does not mean that such members are unable to caucus with members of the political parties. Members can also switch parties at any time, although this is quite uncommon. Article One of the United States Constitution states, "All legislative Powers herein granted shall be vested in a Congress of the United States, which shall consist of
12325-415: The concentration of naturally occurring radioactive materials in coal. A 2008 report from Oak Ridge National Laboratory concluded that coal power actually results in more radioactivity being released into the environment than nuclear power operation, and that the population effective dose equivalent from radiation from coal plants is 100 times that from the operation of nuclear plants. Although coal ash
12470-747: The cusp of World War II , in order to develop a nuclear weapon . In the United States, these research efforts led to the creation of the first man-made nuclear reactor, the Chicago Pile-1 under the Stagg Field stadium at the University of Chicago , which achieved criticality on December 2, 1942. The reactor's development was part of the Manhattan Project , the Allied effort to create atomic bombs during World War II. It led to
12615-409: The decade, global installed nuclear capacity reached 300 GW. Since the late 1980s, new capacity additions slowed significantly, with the installed nuclear capacity reaching 366 GW in 2005. The 1986 Chernobyl disaster in the USSR , involving an RBMK reactor, altered the development of nuclear power and led to a greater focus on meeting international safety and regulatory standards. It
12760-416: The disaster, Japan shut down all of its nuclear power reactors, some of them permanently, and in 2015 began a gradual process to restart the remaining 40 reactors, following safety checks and based on revised criteria for operations and public approval. In 2022, the Japanese government, under the leadership of Prime Minister Fumio Kishida , declared that 10 more nuclear power plants were to be reopened since
12905-612: The early years as political parties became pronounced. With the passage of the Constitution and the Bill of Rights , the anti-federalist movement was exhausted. Some activists joined the Anti-Administration Party that James Madison and Thomas Jefferson were forming about 1790–1791 to oppose policies of Treasury Secretary Alexander Hamilton ; it soon became the Democratic-Republican Party or
13050-487: The electorate. Lame duck reforms according to the Twentieth Amendment reduced the power of defeated and retiring members of Congress to wield influence despite their lack of accountability. The Great Depression ushered in President Franklin Roosevelt and strong control by Democrats and historic New Deal policies. Roosevelt 's election in 1932 marked a shift in government power towards
13195-425: The exclusive power of removal , allowing impeachment and removal of the president, federal judges and other federal officers. There have been charges that presidents acting under the doctrine of the unitary executive have assumed important legislative and budgetary powers that should belong to Congress. So-called signing statements are one way in which a president can "tip the balance of power between Congress and
13340-536: The executive branch. Numerous New Deal initiatives came from the White House rather initiated by Congress. President Roosevelt pushed his agenda in Congress by detailing Executive Branch staff to friendly Senate committees (a practice that ended with the Legislative Reorganization Act of 1946). The Democratic Party controlled both houses of Congress for many years. During this time, Republicans and conservative southern Democrats formed
13485-463: The extent of congressional versus presidential power regarding war has been present periodically throughout the nation's history. Congress can establish post offices and post roads, issue patents and copyrights , fix standards of weights and measures, establish Courts inferior to the Supreme Court , and "make all Laws which shall be necessary and proper for carrying into Execution the foregoing Powers, and all other Powers vested by this Constitution in
13630-564: The fear of communism during the Second Red Scare and conducted televised hearings. In 1960, Democratic candidate John F. Kennedy narrowly won the presidency and power shifted again to the Democrats who dominated both chambers of Congress from 1961 to 1980, and retained a consistent majority in the House from 1955 to 1994. Congress enacted Johnson's Great Society program to fight poverty and hunger. The Watergate Scandal had
13775-412: The first woman of color to reach the Senate in 1993. The second, Mazie Hirono , won in 2013. In 2021, Kamala Harris became the first female President of the Senate , which came with her role as the first female Vice President of the United States . Article One of the Constitution creates and sets forth the structure and most of the powers of Congress. Sections One through Six describe how Congress
13920-456: The full energy potential of the original uranium. The main constituent of spent fuel from LWRs is slightly enriched uranium . This can be recycled into reprocessed uranium (RepU), which can be used in a fast reactor, used directly as fuel in CANDU reactors, or re-enriched for another cycle through an LWR. Re-enriching of reprocessed uranium is common in France and Russia. Reprocessed uranium
14065-436: The gap between power and expansion of infrastructure, NEI suggests maintaining existing nuclear power plants. This suggestion is made with the knowledge that after a power plant has closed, it is gone forever. NEI also advocates for more nuclear power infrastructure due to hundreds of jobs being created and consistent for the years to come. NEI advocates for nuclear energy due to it being the largest source of clean energy within
14210-521: The heart of France's drive for carbon neutrality by 2050. Meanwhile, in the United States, the Department of Energy , in collaboration with commercial entities, TerraPower and X-energy , is planning on building two different advanced nuclear reactors by 2027, with further plans for nuclear implementation in its long term green energy and energy security goals. Nuclear power plants are thermal power stations that generate electricity by harnessing
14355-578: The highest output mines are remote underground operations, such as McArthur River uranium mine , in Canada, which by itself accounts for 13% of global production. As of 2011 the world's known resources of uranium, economically recoverable at the arbitrary price ceiling of US$ 130/kg, were enough to last for between 70 and 100 years. In 2007, the OECD estimated 670 years of economically recoverable uranium in total conventional resources and phosphate ores assuming
14500-425: The importance of low-carbon generation for mitigating climate change . As of 2015 , the global trend was for new nuclear power stations coming online to be balanced by the number of old plants being retired. In 2016, the U.S. Energy Information Administration projected for its "base case" that world nuclear power generation would increase from 2,344 terawatt hours (TWh) in 2012 to 4,500 TWh in 2040. Most of
14645-638: The industry and the expansion of nuclear energy, a number of which have come under attack from environmentalists and anti-nuclear activists. In 2006, NEI founded the Clean and Safe Energy Coalition (CASEnergy) to help build local support around the country for new nuclear construction. The co-chairs of the coalition are early Greenpeace member Patrick Moore and former United States Environmental Protection Agency Secretary and New Jersey Governor Christine Todd Whitman . As of April 2006, CASEnergy boasted 427 organizations and 454 individuals as members. In April 2004,
14790-402: The internal structure of Congress is important to understand along with its interactions with so-called intermediary institutions such as political parties , civic associations , interest groups , and the mass media . The Congress of the United States serves two distinct purposes that overlap: local representation to the federal government of a congressional district by representatives and
14935-486: The lack of term limits favored incumbent white men, making the widow's succession – in which a woman temporarily took over a seat vacated by the death of her husband – the most common path to Congress for white women. Women candidates began making substantial inroads in the later 20th century, due in part to new political support mechanisms and public awareness of their underrepresentation in Congress. Recruitment and financial support for women candidates were rare until
15080-574: The largest earthquakes ever recorded. The Fukushima Daiichi Nuclear Power Plant suffered three core meltdowns due to failure of the emergency cooling system for lack of electricity supply. This resulted in the most serious nuclear accident since the Chernobyl disaster. The accident prompted a re-examination of nuclear safety and nuclear energy policy in many countries. Germany approved plans to close all its reactors by 2022, and many other countries reviewed their nuclear power programs. Following
15225-551: The late 1970s. During the 1970s and 1980s rising economic costs (related to extended construction times largely due to regulatory changes and pressure-group litigation) and falling fossil fuel prices made nuclear power plants then under construction less attractive. In the 1980s in the U.S. and 1990s in Europe, the flat electric grid growth and electricity liberalization also made the addition of large new baseload energy generators economically unattractive. The 1973 oil crisis had
15370-430: The late 20th century, the media became more important in Congress's work. Analyst Michael Schudson suggested that greater publicity undermined the power of political parties and caused "more roads to open up in Congress for individual representatives to influence decisions". Norman Ornstein suggested that media prominence led to a greater emphasis on the negative and sensational side of Congress, and referred to this as
15515-488: The law. Generally militia forces are controlled by state governments, not Congress. Congress also has implied powers deriving from the Constitution's Necessary and Proper Clause which permit Congress to "make all laws which shall be necessary and proper for carrying into Execution the foregoing Powers, and all other Powers vested by this Constitution in the Government of the United States, or in any Department or Officer thereof". Broad interpretations of this clause and of
15660-616: The law; agreed that the advertisements were directed to policymakers and opinion leaders in forums that principally reach those who set national policy on energy and environmental issues, and therefore did not constitute "commercial speech"; noted that in different circumstances, such as direct marketing of electricity, such advertising could be considered commercial speech and be subject to stricter substantiation. NEI ran other ads with similar content, most recently one released in September 2006 touting nuclear energy's non-emitting character and
15805-441: The legislature since there were two separate chambers. The new government became active in 1789. Political scientist Julian E. Zelizer suggested there were four main congressional eras, with considerable overlap, and included the formative era (1780s–1820s), the partisan era (1830s–1900s), the committee era (1910s–1960s), and the contemporary era (1970–present). Federalists and anti-federalists jostled for power in
15950-516: The life of nuclear fuel to a few years. In some countries, such as the United States, spent fuel is classified in its entirety as a nuclear waste. In other countries, such as France, it is largely reprocessed to produce a partially recycled fuel, known as mixed oxide fuel or MOX . For spent fuel that does not undergo reprocessing, the most concerning isotopes are the medium-lived transuranic elements , which are led by reactor-grade plutonium (half-life 24,000 years). Some proposed reactor designs, such as
16095-469: The lifetime of a facility and saved in a decommissioning fund. United States Congress Minority (49) Minority (212) Vacant (3) [REDACTED] [REDACTED] The United States Congress is the legislature of the federal government of the United States . It is bicameral , composed of a lower body, the United States House of Representatives , and an upper body,
16240-719: The majority from France, 17% from Germany, and 9% from Japan. Breeding is the process of converting non-fissile material into fissile material that can be used as nuclear fuel. The non-fissile material that can be used for this process is called fertile material , and constitute the vast majority of current nuclear waste. This breeding process occurs naturally in breeder reactors . As opposed to light water thermal-neutron reactors, which use uranium-235 (0.7% of all natural uranium), fast-neutron breeder reactors use uranium-238 (99.3% of all natural uranium) or thorium. A number of fuel cycles and breeder reactor combinations are considered to be sustainable or renewable sources of energy. In 2006 it
16385-488: The mid-1970s anti-nuclear activism gained a wider appeal and influence, and nuclear power began to become an issue of major public protest. In some countries, the nuclear power conflict "reached an intensity unprecedented in the history of technology controversies". The increased public hostility to nuclear power led to a longer license procurement process, more regulations and increased requirements for safety equipment, which made new construction much more expensive. In
16530-437: The most common type of reactor, this concentration is too low, and it must be increased by a process called uranium enrichment . In civilian light water reactors, uranium is typically enriched to 3.5–5% uranium-235. The uranium is then generally converted into uranium oxide (UO 2 ), a ceramic, that is then compressively sintered into fuel pellets, a stack of which forms fuel rods of the proper composition and geometry for
16675-418: The most hazardous substances in nuclear waste), there is an estimated 160,000 years worth of uranium in total conventional resources and phosphate ore at the price of 60–100 US$ /kg. However, reprocessing is expensive, possibly dangerous and can be used to manufacture nuclear weapons. One analysis found that uranium prices could increase by two orders of magnitude between 2035 and 2100 and that there could be
16820-428: The natural process of uranium dissolved from the surface area of the ocean floor, both of which maintain the solubility equilibria of seawater concentration at a stable level. Some commentators have argued that this strengthens the case for nuclear power to be considered a renewable energy . The normal operation of nuclear power plants and facilities produce radioactive waste , or nuclear waste. This type of waste
16965-432: The near future. Most nuclear power plants use thermal reactors with enriched uranium in a once-through fuel cycle . Fuel is removed when the percentage of neutron absorbing atoms becomes so large that a chain reaction can no longer be sustained, typically three years. It is then cooled for several years in on-site spent fuel pools before being transferred to long-term storage. The spent fuel, though low in volume,
17110-416: The once-through fuel cycle. While reprocessing reduces the volume of high-level waste, it does not reduce the fission products that are the primary causes of residual heat generation and radioactivity for the first few centuries outside the reactor. Thus, reprocessed waste still requires an almost identical treatment for the initial first few hundred years. Reprocessing of civilian fuel from power reactors
17255-584: The other branches of government. In the Plame affair , critics including Representative Henry A. Waxman charged that Congress was not doing an adequate job of oversight in this case. There have been concerns about congressional oversight of executive actions such as warrantless wiretapping , although others respond that Congress did investigate the legality of presidential decisions. Political scientists Ornstein and Mann suggested that oversight functions do not help members of Congress win reelection. Congress also has
17400-469: The particular reactor. After some time in the reactor, the fuel will have reduced fissile material and increased fission products, until its use becomes impractical. At this point, the spent fuel will be moved to a spent fuel pool which provides cooling for the thermal heat and shielding for ionizing radiation. After several months or years, the spent fuel is radioactively and thermally cool enough to be moved to dry storage casks or reprocessed. Uranium
17545-497: The predicted increase was expected to be in Asia. As of 2018, there were over 150 nuclear reactors planned including 50 under construction. In January 2019, China had 45 reactors in operation, 13 under construction, and planned to build 43 more, which would make it the world's largest generator of nuclear electricity. As of 2021, 17 reactors were reported to be under construction. China built significantly fewer reactors than originally planned. Its share of electricity from nuclear power
17690-771: The preservation of nuclear plants and used nuclear fuel storage. The association represents the nuclear industry's interests before Congress and the Nuclear Regulatory Commission . It often produces research reports and testifies at federal and state congressional hearings. The nuclear energy industry that NEI represents and serves includes: Commercial electricity generation, nuclear medicine including diagnostics and therapy, food processing and agricultural applications, industrial and manufacturing applications, uranium mining and processing, nuclear fuel and radioactive materials manufacturing, transportation of radioactive materials, and nuclear waste management NEI
17835-511: The primary motivations of the anti-nuclear movement , which contends that nuclear power poses many threats to people and the environment, citing the potential for accidents like the Fukushima nuclear disaster in Japan in 2011, and is too expensive/slow to deploy when compared to alternative sustainable energy sources. Nuclear fission was discovered in 1938 after over four decades of work on
17980-630: The private sector. The first organization to develop practical nuclear power was the U.S. Navy , with the S1W reactor for the purpose of propelling submarines and aircraft carriers . The first nuclear-powered submarine, USS Nautilus , was put to sea in January 1954. The S1W reactor was a pressurized water reactor . This design was chosen because it was simpler, more compact, and easier to operate compared to alternative designs, thus more suitable to be used in submarines. This decision would result in
18125-597: The process for going to war, they asked for and received formal war declarations from Congress for the War of 1812 , the Mexican–American War , the Spanish–American War , World War I , and World War II , although President Theodore Roosevelt 's military move into Panama in 1903 did not get congressional approval. In the early days after the North Korean invasion of 1950 , President Truman described
18270-703: The ranks of citizens and the nation grew at a rapid pace. The Progressive Era was characterized by strong party leadership in both houses of Congress and calls for reform; sometimes reformers said lobbyists corrupted politics. The position of Speaker of the House became extremely powerful under leaders such as Thomas Reed in 1890 and Joseph Gurney Cannon . By the beginning of the 20th century, party structures and leadership emerged as key organizers of Senate proceedings. A system of seniority, in which long-time members of Congress gained more and more power, encouraged politicians of both parties to seek long terms. Committee chairmen remained influential in both houses until
18415-462: The reaction rate is contained by control rods that absorb excess neutrons. The controllability of nuclear reactors depends on the fact that a small fraction of neutrons resulting from fission are delayed . The time delay between the fission and the release of the neutrons slows changes in reaction rates and gives time for moving the control rods to adjust the reaction rate. The life cycle of nuclear fuel starts with uranium mining . The uranium ore
18560-504: The reforms of the 1970s. Important structural changes included the direct popular election of senators according to the Seventeenth Amendment , ratified on April 8, 1913. Supreme Court decisions based on the Constitution's commerce clause expanded congressional power to regulate the economy. One effect of popular election of senators was to reduce the difference between the House and Senate in terms of their link to
18705-637: The restart of another ten reactors. Prime Minister Fumio Kishida in July 2022 announced that the country should consider building advanced reactors and extending operating licences beyond 60 years. As of 2022, with world oil and gas prices on the rise, while Germany is restarting its coal plants to deal with loss of Russian gas that it needs to supplement its Energiewende , many other countries have announced ambitious plans to reinvigorate ageing nuclear generating capacity with new investments. French President Emmanuel Macron announced his intention to build six new reactors in coming decades, placing nuclear at
18850-406: The role it can play in reducing American dependence on foreign sources of fossil fuels like oil and natural gas. In 2008, Greenpeace criticized NEI's public relations efforts and suggested that NEI's advertising about nuclear power was an example of greenwashing . In the first quarter of 2008, NEI spent $ 320,000 on lobbying the US federal government. Besides Congress , the nuclear group lobbied
18995-450: The science of radioactivity and the elaboration of new nuclear physics that described the components of atoms . Soon after the discovery of the fission process, it was realized that a fissioning nucleus can induce further nucleus fissions, thus inducing a self-sustaining chain reaction. Once this was experimentally confirmed in 1939, scientists in many countries petitioned their governments for support for nuclear fission research, just on
19140-512: The second-largest low-carbon power source after hydroelectricity . As of November 2024, there are 415 civilian fission reactors in the world , with overall capacity of 374 GW, 66 under construction and 87 planned, with a combined capacity of 72 GW and 84 GW, respectively. The United States has the largest fleet of nuclear reactors, generating almost 800 TWh of low-carbon electricity per year with an average capacity factor of 92%. The average global capacity factor
19285-413: The several States, and without regard to any census or enumeration. The Constitution also grants Congress the exclusive power to appropriate funds, and this power of the purse is one of Congress's primary checks on the executive branch. Congress can borrow money on the credit of the United States, regulate commerce with foreign nations and among the states, and coin money. Generally, the Senate and
19430-426: The spent fuel becomes less radioactive than natural uranium ore. Commonly suggested methods to isolate LLFP waste from the biosphere include separation and transmutation , synroc treatments, or deep geological storage. Thermal-neutron reactors , which presently constitute the majority of the world fleet, cannot burn up the reactor grade plutonium that is generated during the reactor operation. This limits
19575-736: The spirit of the Constitution. There have been concerns that presidential authority to cope with financial crises is eclipsing the power of Congress. In 2008, George F. Will called the Capitol building a "tomb for the antiquated idea that the legislative branch matters". The Constitution enumerates the powers of Congress in detail. In addition, other congressional powers have been granted, or confirmed, by constitutional amendments. The Thirteenth (1865), Fourteenth (1868), and Fifteenth Amendments (1870) gave Congress authority to enact legislation to enforce rights of African Americans, including voting rights , due process , and equal protection under
19720-417: The then-current use rate. Light water reactors make relatively inefficient use of nuclear fuel, mostly using only the very rare uranium-235 isotope. Nuclear reprocessing can make this waste reusable, and newer reactors also achieve a more efficient use of the available resources than older ones. With a pure fast reactor fuel cycle with a burn up of all the uranium and actinides (which presently make up
19865-524: The use of a thorium fuel cycle in the third stage, as it has abundant thorium reserves but little uranium. Nuclear decommissioning is the process of dismantling a nuclear facility to the point that it no longer requires measures for radiation protection, returning the facility and its parts to a safe enough level to be entrusted for other uses. Due to the presence of radioactive materials, nuclear decommissioning presents technical and economic challenges. The costs of decommissioning are generally spread over
20010-457: The vast majority of electricity from nuclear power is produced by nuclear fission of uranium and plutonium in nuclear power plants . Nuclear decay processes are used in niche applications such as radioisotope thermoelectric generators in some space probes such as Voyager 2 . Reactors producing controlled fusion power have been operated since 1958, but have yet to generate net power and are not expected to be commercially available in
20155-563: Was 5% in 2019 and observers have cautioned that, along with the risks, the changing economics of energy generation may cause new nuclear energy plants to "no longer make sense in a world that is leaning toward cheaper, more reliable renewable energy". In October 2021, the Japanese cabinet approved the new Plan for Electricity Generation to 2030 prepared by the Agency for Natural Resources and Energy (ANRE) and an advisory committee, following public consultation. The nuclear target for 2030 requires
20300-547: Was able to effectively block a large component of exposure in this population". One of NEI's main focuses is advocating for policies that would promote beneficial uses of nuclear energy. NEI utilizes the National Nuclear Energy Strategy which has four main points that they want to hit when guiding policy: preserve, sustain, innovate, and thrive. Preservation aims to keep and preserve the current nuclear power plants that are still in use today. Sustain
20445-466: Was connected to the national power grid on 27 August 1956. In common with a number of other generation I reactors , the plant had the dual purpose of producing electricity and plutonium-239 , the latter for the nascent nuclear weapons program in Britain . The total global installed nuclear capacity initially rose relatively quickly, rising from less than 1 gigawatt (GW) in 1960 to 100 GW in
20590-399: Was created as a direct outcome of the 1986 Chernobyl accident. The Chernobyl disaster played a major part in the reduction in the number of new plant constructions in the following years. Influenced by these events, Italy voted against nuclear power in a 1987 referendum, becoming the first country to completely phase out nuclear power in 1990. In the early 2000s, nuclear energy was expecting
20735-551: Was created by the U.S. Constitution and first met in 1789, replacing the Congress of the Confederation in its legislative function. Although not legally mandated, in practice since the 19th century, members of Congress are typically affiliated with one of the two major parties , the Democratic Party or the Republican Party , and only rarely with a third party or independents affiliated with no party. In
20880-420: Was estimated that with seawater extraction, there was likely five billion years' worth of uranium resources for use in breeder reactors. Breeder technology has been used in several reactors, but as of 2006, the high cost of reprocessing fuel safely requires uranium prices of more than US$ 200/kg before becoming justified economically. Breeder reactors are however being developed for their potential to burn all of
21025-692: Was generated for the first time by a nuclear reactor on December 20, 1951, at the EBR-I experimental station near Arco, Idaho , which initially produced about 100 kW . In 1953, American President Dwight Eisenhower gave his " Atoms for Peace " speech at the United Nations , emphasizing the need to develop "peaceful" uses of nuclear power quickly. This was followed by the Atomic Energy Act of 1954 which allowed rapid declassification of U.S. reactor technology and encouraged development by
