122-560: During the first 40 years that nuclear waste was being created in the United States , no legislation was enacted to manage its disposal. Nuclear waste, some of which remains radioactive with a half-life of more than one million years, was kept in various types of temporary storage. Of particular concern during nuclear waste disposal are two long-lived fission products, Tc-99 (half-life 220,000 years) and I-129 (half-life 17 million years), which dominate spent fuel radioactivity after

610-540: A Presidential Memorandum dated January 29, 2010, President Obama established the Blue Ribbon Commission on America's Nuclear Future. The commission, composed of fifteen members, conducted an extensive two-year study of nuclear waste disposal, what is referred to as the "back end" of the nuclear energy process. The commission established three subcommittees: Reactor and Fuel Cycle Technology, Transportation and Storage, and Disposal. During their research

732-542: A coordinated, continent-wide military effort. Finally, deteriorating relations between the British military establishment and the colonists, relations that were already less than positive, set the stage for further distrust and dislike of British troops.

1098-730: A few thousand years. The most troublesome transuranic elements in spent fuel are Np-237 (half-life two million years) and Pu-239 (half-life 24,000 years). Most existing nuclear waste came from production of nuclear weapons . About 77 million gallons of military nuclear waste in liquid form was stored in steel tanks, mostly in South Carolina , Washington , and Idaho . In the private sector, 82 nuclear plants operating in 1982 used uranium fuel to produce electricity. Highly radioactive spent fuel rods were stored in pools of water at reactor sites, but many utilities were running out of storage space. The Nuclear Waste Policy Act of 1982 created

1586-447: A permanent radioactive waste repository has yet been discovered that has been stable for so long a period. Because some radioactive species have half-lives longer than one million years, even very low container leakage and radionuclide migration rates must be taken into account. Moreover, it may require more than one half-life until some nuclear waste loses enough radioactivity so that it is no longer lethal to humans. Waste containers have

1708-575: A permanent waste repository went into operation. Costs of temporary storage would be paid by fees collected from electric utilities using the storage. The Act required the Secretary of Energy to report to Congress by June 1, 1985, on the need for and feasibility of a monitored retrievable storage facility (MRS) and specified that the report was to include five different combinations of proposed sites and facility designs, involving at least three different locations. Environmental assessments were required for

2562-710: A timetable and procedure for establishing a permanent, underground repository for high-level radioactive waste by the mid-1990s, and provided for some temporary federal storage of waste, including spent fuel from civilian nuclear reactors . State governments were authorized to veto a national government decision to place a waste repository within their borders, and the veto would stand unless both houses of Congress voted to override it. The Act also called for developing plans by 1985 to build monitored retrievable storage (MRS) facilities, where wastes could be kept for 50 to 100 years or more and then be removed for permanent disposal or for reprocessing. Congress assigned responsibility to

9516-403: The compliance time to 10,000 years, EPA did not respect a statutory requirement that it develop standards consistent with NAS recommendations. The EPA subsequently revised the standards to extend out to 1 million years. A license application was submitted in the summer of 2008 and is presently under review by the Nuclear Regulatory Commission. The Obama Administration rejected use of the site in

9638-722: The construction of a MRS facility at the Clinch River Breeder Reactor Site in Oak Ridge, Tennessee. Following considerable public pressure and threat of veto by the Governor of Tennessee, the 1987 amendments to the NWPA "annulled and revoked" MRS plans for all of the proposed sites. There are carefully selected geological locations that build places specifically for disposing nuclear waste in a safe location. The Act required DOE to consult closely throughout

9760-457: The contiguous United States are in the State of California, about 84 miles (135 km) apart. At an elevation of 20,310 feet (6,190.5 m), Alaska's Denali is the highest peak in the country and continent. Active volcanoes are common throughout Alaska's Alexander and Aleutian Islands , and Hawaii consists of volcanic islands. The supervolcano underlying Yellowstone National Park in

9882-556: The country's GDP. The U.S. has 42% of the world's nuclear weapons —the second-largest share after Russia. The United States has the third-largest combined armed forces in the world, behind the Chinese People's Liberation Army and Indian Armed Forces . The military operates about 800 bases and facilities abroad, and maintains deployments greater than 100 active duty personnel in 25 foreign countries. State defense forces (SDFs) are military units that operate under

10004-469: The country's territory would expand with the admission of new states , rather than the expansion of existing states. The U.S. Constitution was drafted at the 1787 Constitutional Convention to overcome the limitations of the Articles. It went into effect in 1789, creating a federal republic governed by three separate branches that together ensured a system of checks and balances . George Washington

10126-713: The development of self-governance, and the First Great Awakening , a series of Christian revivals , fueled colonial interest in religious liberty . For a century, the American colonists had been providing their own troops and materiel in conflicts with indigenous peoples allied with Britain's colonial rivals , especially France, and the Americans had begun to develop a sense of self-defense and self-reliance separate from Britain. The French and Indian War (1754–1763) took on new significance for all North American colonists after Parliament under William Pitt

10248-414: The dispossession of native inhabitants . As more states were admitted , a North–South division over slavery led to the secession of the Confederate States of America , which fought states remaining in the Union in the 1861–1865 American Civil War . With the victory and preservation of the United States, slavery was abolished nationally . By 1900, the country had established itself as a great power ,

10370-814: The end of FY2017. However (according to the Draft Report by the Blue Ribbon Commission on America's Nuclear Future ), actions by both Congress and the Executive Branch have made the money in the fund effectively inaccessible to serving its original purpose. The commission made several recommendations on how this situation may be corrected. In late 2013, a federal court ruled that the Department of Energy must stop collecting fees for nuclear waste disposal until provisions are made to collect nuclear waste. In December 1987, Congress amended

10492-441: The ending of work on the incomplete Yucca Mountain Repository . At present, there are 70 nuclear power plant sites where 65,000 tons of spent fuel is stored in the USA. Each year, more than 2,000 tons are added to this total. Nine states have "explicit moratoria on new nuclear power until a storage solution emerges". A deep geological repository seems to be the favored approach to storing nuclear waste. On January 26, 2012,

10614-580: The environment for labor unions to begin to flourish . This period eventually ended with the advent of the Progressive Era , which was characterized by significant reforms. Pro-American elements in Hawaii overthrew the Hawaiian monarchy ; the islands were annexed in 1898. That same year, Puerto Rico , the Philippines , and Guam were ceded to the U.S. by Spain after the latter's defeat in

10736-541: The federal government often applied policies of Indian removal or assimilation . The Trail of Tears (1830–1850) was a U.S. government policy that forcibly removed and displaced most Native Americans living east of the Mississippi River to lands far to the west. These and earlier organized displacements prompted a long series of American Indian Wars west of the Mississippi. The Republic of Texas

10858-606: The first nuclear weapons and used them against the Japanese cities of Hiroshima and Nagasaki in August 1945, ending the war. The United States was one of the " Four Policemen " who met to plan the post-war world , alongside the United Kingdom , Soviet Union , and China . The U.S. emerged relatively unscathed from the war, with even greater economic power and international political influence . After World War II,

10980-665: The first settlement of the Thirteen Colonies in Virginia in 1607. Clashes with the British Crown over taxation and political representation sparked the American Revolution , with the Second Continental Congress formally declaring independence on July 4, 1776. Following its victory in the 1775–1783 Revolutionary War , the country continued to expand westward across North America , resulting in

11102-844: The human environment. Current policy relinquishes control over radioactive materials to geohydrologic processes at repository closure. Existing models of these processes are empirically underdetermined, meaning there is not much evidence they are accurate. DOE guidelines contain no requirements for permanent offsite or onsite monitoring after closure. This may seem imprudent, considering repositories will contain millions of dollars worth of spent reactor fuel that might be reprocessed and used again either in reactors generating electricity, in weapons applications, or possibly in terrorist activities. Technology for permanently sealing large-bore-hole walls against water infiltration or fracture does not currently exist. Previous experiences sealing mine tunnels and shafts have not been entirely successful, especially where there

11224-463: The integration of Army National Guard units and personnel into the U.S. Army and (since 1947) the U.S. Air Force. There are about 18,000 U.S. police agencies from local to national level in the United States. Law in the United States is mainly enforced by local police departments and sheriff departments in their municipal or county jurisdictions. The state police departments have authority in their respective state , and federal agencies such as

11346-478: The long-term custody problem. Pyroelectric refining, as perfected at EBR-II , separates essentially all actinides from fission products. U.S. DOE Research on pyroelectric refining and fast neutron reactors was stopped in 1994. Current repository closure plans require backfilling of waste disposal rooms, tunnels, and shafts with rubble from initial excavation and sealing openings at the surface, but do not require complete or perpetual isolation of radioactive waste from

11468-482: The military draft (leading to the end of conscription in 1973) and wide opposition to U.S. intervention in Vietnam (with the U.S. totally withdrawing in 1975). A societal shift in the roles of women was significantly responsible for the large increase in female paid labor participation during the 1970s, and by 1985 the majority of American women aged 16 and older were employed. The late 1980s and early 1990s saw

11590-612: The most attractive to the population are the most vulnerable. The U.S. is one of 17 megadiverse countries containing large numbers of endemic species : about 17,000 species of vascular plants occur in the contiguous United States and Alaska, and over 1,800 species of flowering plants are found in Hawaii, few of which occur on the mainland. The United States is home to 428 mammal species, 784 birds, 311 reptiles, 295 amphibians , and around 91,000 insect species. There are 63 national parks , and hundreds of other federally managed parks, forests, and wilderness areas , managed by

11712-662: The most violent, the California genocide of thousands of Native inhabitants, lasted into the early 1870s, just as additional western territories and states were created. During the colonial period, slavery had been legal in the American colonies , though the practice began to be significantly questioned during the American Revolution. States in the North enacted abolition laws , though support for slavery strengthened in Southern states , as inventions such as

11834-432: The national government to take ownership of all nuclear waste or spent fuel at the reactor site, transport it to the repository, and thereafter be responsible for its containment. The Act authorized DOE to provide up to 1,900 metric tons of temporary storage capacity for spent fuel from civilian nuclear reactors. It required that spent fuel in temporary storage facilities be moved to permanent storage within three years after

11956-541: The permanent repository was licensed. Early in 2002, the Secretary of Energy recommended approval of Yucca Mountain for development of a repository based on the multiple factors as required in the Nuclear Waste Policy Act of 1987 and, after review, President George W. Bush submitted the recommendation to Congress for its approval. Nevada exercised its state veto in April 2002, but the veto was overridden by both houses of Congress by mid-July 2002. In 2004,

12078-408: The policy of redlining later adopted by the federal Home Owners' Loan Corporation . An explosion of technological advancement accompanied by the exploitation of cheap immigrant labor led to rapid economic expansion during the late 19th and early 20th centuries , allowing the United States to outpace the economies of England, France, and Germany combined. This fostered the amassing of power by

12200-574: The primary colonial grievances was a denial of their rights as Englishmen , particularly the right to representation in the British government that taxed them . To demonstrate their dissatisfaction and resolve, the First Continental Congress met in 1774 and passed the Continental Association , a colonial boycott of British goods that proved effective. The British attempt to then disarm the colonists resulted in

12322-611: The quantities of poison are tremendous. It is very difficult to satisfy these requirements for the simple reason that we have had no practical experience with such a long term project. Moreover permanently guarded storage requires a society with unprecedented stability." Thus, Alfvén identified two fundamental prerequisites for effective management of high-level radioactive waste: (1) stable geological formations, and (2) stable human institutions over hundreds of thousands of years. However, no known human civilization has ever endured for so long. Moreover, no geologic formation of adequate size for

12444-570: The rights of African Americans . National infrastructure, including transcontinental telegraph and railroads , spurred growth in the American frontier . From 1865 through 1917 an unprecedented stream of immigrants arrived in the United States, including 24.4 million from Europe. Most came through the port of New York City , and New York City and other large cities on the East Coast became home to large Jewish , Irish , and Italian populations, while many Germans and Central Europeans moved to

12566-614: The rocky Great Basin and Chihuahua , Sonoran , and Mojave deserts. In the northwest corner of Arizona , carved by the Colorado River over millions of years, is the Grand Canyon , a steep-sided canyon and popular tourist destination known for its overwhelming visual size and intricate, colorful landscape. The Sierra Nevada and Cascade mountain ranges run close to the Pacific coast . The lowest and highest points in

12688-427: The site selection process with states or Indian tribes that might be affected by the location of a waste facility, and allowed a state (governor or legislature) or Indian tribe to veto a federal decision to place within its borders a waste repository or temporary storage facility holding 300 tons or more of spent fuel, but provided that the veto could be overruled by a vote of both houses of Congress. The Act established

12810-491: The sites. It barred construction of a MRS facility in a state under consideration for a permanent waste repository. The DOE in 1985 recommended an integral MRS facility. Of the eleven sites identified within the preferred geographic region, the DOE selected three sites in Tennessee for further study. In March 1987, after more than a year of legal action in the federal courts, the DOE submitted its final proposal to Congress for

12932-573: The six service branches, which are made up of the U.S. Army , Marine Corps , Navy , Air Force , and Space Force . The Coast Guard is administered by the Department of Homeland Security in peacetime and can be transferred to the Department of the Navy in wartime. The United States spent $ 916 billion on its military in 2023, which is by far the largest amount of any country , making up 37% of global military spending and accounting for 3.4% of

13054-545: The sole authority of a state government. SDFs are authorized by state and federal law but are under the command of the state's governor . They are distinct from the state's National Guard units in that they cannot become federalized entities. A state's National Guard personnel, however, may be federalized under the National Defense Act Amendments of 1933 , which created the Guard and provides for

13176-543: The states are also represented by local elected governments , which are administrative divisions of the states. States are subdivided into counties or county equivalents , and further divided into municipalities . The District of Columbia is a federal district containing the U.S. capital, Washington, D.C. . The federal district is an administrative division of the federal government. Federally recognized tribes govern 326 Indian reservations . The United States has an established structure of foreign relations, and it has

13298-451: The structure and responsibilities of the national federal government and its relationship with the individual states. The U.S. Constitution is the world's oldest national constitution still in effect (from March 4, 1789). Composed of three branches, all headquartered in Washington, D.C., the federal government is the national government of the United States. It is regulated by a strong system of checks and balances . The three-branch system

13420-538: The surface, so the standard applied to natural geologic pathways was more stringent than the standard applied to artificial pathways of radionuclide travel created during construction of the facility. Enrico Fermi described an alternative solution: Consume all actinides in fast neutron reactors, leaving only fission products requiring special custody for less than 300 years. This requires continuous fuel reprocessing. PUREX separates plutonium and uranium, but leaves other actinides with fission products, thereby not addressing

13542-458: The underground facility) was expected to be less than 1,000 years along any pathway of radionuclide travel. Sites with groundwater travel time greater than 1,000 years from the original location to the human environment were considered potentially acceptable, even if the waste would be highly radioactive for 200,000 years or more. Moreover, the term "disturbed zone" was defined in the regulations to exclude shafts drilled into geologic structures from

13664-582: The world's fourth-longest river system , runs predominantly north–south through the heart of the country. The flat and fertile prairie of the Great Plains stretches to the west, interrupted by a highland region in the southeast. The Rocky Mountains , west of the Great Plains, extend north to south across the country, peaking at over 14,000 feet (4,300 m) in Colorado . Farther west are

13786-583: The world's second-largest diplomatic corps as of 2024 . It is a permanent member of the United Nations Security Council , and home to the United Nations headquarters . The United States is a member of the G7 , G20 , and OECD intergovernmental organizations. Almost all countries have embassies and many have consulates (official representatives) in the country. Likewise, nearly all countries host formal diplomatic missions with

13908-461: The world's third-largest land area , largest exclusive economic zone , and third-largest population , exceeding 334 million. Its three largest metropolitan areas are New York , Los Angeles , and Chicago , and its three most populous states are California , Texas , and Florida . Paleo-Indians migrated across the Bering land bridge more than 12,000 years ago, and formed various civilizations and societies . British colonization led to

14030-444: The world's oldest surviving federation, and its presidential system of national government has been adopted, in whole or in part, by many newly independent states worldwide following their decolonization . It is a liberal representative democracy "in which majority rule is tempered by minority rights protected by law ". The Constitution of the United States serves as the country's supreme legal document , also establishing

14152-553: The world's tornadoes occur in the country , mainly in Tornado Alley . Overall, the United States receives more high-impact extreme weather incidents than any other country. Extreme weather became more frequent in the U.S. in the 21st century, with three times the number of reported heat waves as in the 1960s. In the American Southwest , droughts became more persistent and more severe. The regions considered as

14274-613: The world, with almost 2 million people incarcerated . An analysis of the World Health Organization Mortality Database from 2010 showed U.S. homicide rates "were 7 times higher than in other high-income countries, driven by a gun homicide rate that was 25 times higher". Blue Ribbon Commission on America%27s Nuclear Future A Blue Ribbon Commission on America's Nuclear Future was appointed by President Obama to look into future options for existing and future nuclear waste , following

14396-575: Was annexed in 1845, and the 1846 Oregon Treaty led to U.S. control of the present-day American Northwest . Victory in the Mexican–American War resulted in the 1848 Mexican Cession of California, Nevada, Utah, and much of present-day Colorado and the American Southwest . The California gold rush of 1848–1849 spurred a huge migration of white settlers to the Pacific coast, leading to even more confrontations with Native populations. One of

14518-759: Was adopted on July 4, 1776. The political values of the American Revolution included liberty , inalienable individual rights ; and the sovereignty of the people ; supporting republicanism and rejecting monarchy , aristocracy , and all hereditary political power; civic virtue ; and vilification of political corruption . The Founding Fathers of the United States , who included Washington, Jefferson, John Adams , Benjamin Franklin , Alexander Hamilton , John Jay , James Madison , Thomas Paine , and many others, were inspired by Greco-Roman , Renaissance , and Enlightenment philosophies and ideas. The Articles of Confederation were ratified in 1781 and established

14640-583: Was elected the country's first president under the Constitution, and the Bill of Rights was adopted in 1791 to allay skeptics' concerns about the power of the more centralized government. His resignation as commander-in-chief after the Revolutionary War and his later refusal to run for a third term as the country's first president established a precedent for the supremacy of civil authority in

14762-420: Was required to review site recommendations and submit to Congress by March 31, 1987, his recommendation of one site for the first repository, and by March 31, 1990, his recommendation for a second repository. The amount of high-level waste or spent fuel that could be placed in the first repository was limited to the equivalent of 70,000 metric tons of heavy metal until a second repository was built. The Act required

14884-466: Was zeroed out for the next ten years and it proposed to dissolve the Office of Civilian Waste Management required by the NWPA. In late February 2010, multiple lawsuits were proposed and/or being filed in various federal courts across the country to contest the legality of Chu's direction to DOE to withdraw the license application. These lawsuits were evidently foreseen as eventually being necessary to enforce
