120-766: The rail line Tri-City Railroad operates on is located in Richland, Washington and owned by the Port of Benton. Called the Southern Connection, it was constructed between 1949 and 1950 as a link to the rail lines inside the Hanford Nuclear Reservation . Tri-City Railroad contracted with Pacific Northwest National Laboratory in 2005 to assist in developing the Radiation Portal Monitoring System technology for

240-557: A German atomic bomb project would develop one first, especially among scientists who were refugees from Nazi Germany and other fascist countries. In August 1939, Hungarian-born physicists Leo Szilard and Eugene Wigner drafted the Einstein–Szilard letter , which warned of the potential development of "extremely powerful bombs of a new type". It urged the United States to acquire stockpiles of uranium ore and accelerate

360-755: A neutron moderator . The S-1 Committee recommended pursuing all five technologies. This was approved by Bush, Conant, and Brigadier General Wilhelm D. Styer , who had been designated the Army's representative on nuclear matters. Bush and Conant then took the recommendation to the Top Policy Group with a budget proposal for $ 54 million for construction by the United States Army Corps of Engineers , $ 31 million for research and development by OSRD and $ 5 million for contingencies in fiscal year 1943. They sent it on 17 June 1942, to

480-619: A AAA rating whenever it was required. Nelson initially balked but quickly caved in when Groves threatened to go to the President. Groves promised not to use the AAA rating unless it was necessary. It soon transpired that for the routine requirements of the project the AAA rating was too high but the AA-3 rating was too low. After a long campaign, Groves finally received AA-1 authority on 1 July 1944. According to Groves, "In Washington you became aware of

600-725: A Benton County court found it had breached the terms of its 2002 lease and failed to maintain the tracks. The railroad ceased operations in July 2022. In February 2023, the Port of Benton contracted with Columbia Rail Group, based in Walla Walla, Washington, to operate and maintain the tracks formerly managed by the Tri-City Railroad.

On the west, the Yakima Valley appellation includes 5,000 hectares. To the east, the Walla Walla Valley appellation includes 500 hectares of wine grapes. The Tri-City Industrial Development Council promotes both agricultural-related and technology-related industries in

840-404: A city. Among the first additions to the new city was an expanded public library, which had been built by General Electric out of a Quonset hut . As part of the transition, large areas of undeveloped land became city property. Richland's financial dependency on the federal Hanford facility changed little at this time because Hanford's mission as a weapons materials production site continued during

960-665: A fission bomb was theoretically possible. The properties of pure uranium-235 were relatively unknown, as were those of plutonium, which had only been isolated by Glenn Seaborg and his team in February 1941. The scientists at the July 1942 conference envisioned creating plutonium in nuclear reactors where uranium-238 atoms absorbed neutrons that had been emitted from fissioning uranium-235. At this point no reactor had been built, and only tiny quantities of plutonium were available from cyclotrons . Even by December 1943, only two milligrams had been produced. There were many ways of arranging

1080-551: A letter of the alphabet, and so came to be known as alphabet houses. Richland's link to the Army Engineers is suggested by its street nomenclature; many of the streets are named after famous engineers. The main street ( George Washington Way) is named after the first president, who was a surveyor; Stevens Drive is named after John Frank Stevens , chief engineer of the Panama Canal and Stevens Pass ; Goethals Drive

1200-884: A liaison office in Washington, D.C., but established his temporary headquarters at 270 Broadway in New York, where he could draw on administrative support from the Corps of Engineers' North Atlantic Division . It was close to the Manhattan office of Stone & Webster , the principal project contractor, and to Columbia University. He had permission to draw on his former command, the Syracuse District, for staff, and he started with Lieutenant Colonel Kenneth Nichols , who became his deputy. Because most of his task involved construction, Marshall worked in cooperation with

1320-486: A meeting called by Stimson, which established a Military Policy Committee, responsible to the Top Policy Group, consisting of Bush (with Conant as an alternate), Styer and Rear Admiral William R. Purnell . Tolman and Conant were later appointed as Groves' scientific advisers. On 19 September, Groves went to Donald Nelson , the chairman of the War Production Board, and asked for broad authority to issue

1440-527: A permanent bridge over the Yakima River in 1907 and a highway to Kennewick in 1926. A cable ferry to Pasco operated across the Columbia River from 1894 to 1931, when it was replaced by a modern bridge. Richland was a small farm town until the U.S. Army purchased 640 sq mi (1,660 km ) of land – half the size of Rhode Island – along the Columbia River during World War II for

1560-578: A plant, much less four of them for $ 90 million." A single TNT plant that Nichols had recently built in Pennsylvania had cost $ 128 million. Nor were they impressed with estimates to the nearest order of magnitude, which Groves compared with telling a caterer to prepare for between ten and a thousand guests. A survey team from Stone & Webster had already scouted a site for the production plants. The War Production Board recommended sites around Knoxville, Tennessee , an isolated area where

1680-504: A possible source of bombs with a destructiveness vastly greater than anything now known." In February 1940, the U.S. Navy awarded Columbia University $ 6,000, most of which Fermi and Szilard spent on graphite . A team of Columbia professors including Fermi, Szilard, Eugene T. Booth and John Dunning created the first nuclear fission reaction in the Americas, verifying the work of Hahn and Strassmann. The same team subsequently built

1800-480: A ranch. On 16 November 1942, Oppenheimer, Groves, Dudley and others toured the vicinity of the Los Alamos Ranch School . Oppenheimer expressed a strong preference for the site, citing its natural beauty, which, it was hoped, would inspire those working on the project. The engineers were concerned about the poor access road, and whether the water supply would be adequate, but otherwise felt that it

1920-469: A reaction becomes self-sustaining became known as "going critical". Compton reported the success to Conant in Washington, D.C., by a coded phone call, saying, "The Italian navigator [Fermi] has just landed in the new world." In January 1943, Grafton's successor, Major Arthur V. Peterson , ordered Chicago Pile-1 dismantled and reassembled at the Argonne Forest site, as he regarded the operation of

2040-619: A reactor as too hazardous for a densely populated area. The new site, still operated by the Metallurgical Laboratory, became known as ' Site A '. Chicago Pile-3 , the first heavy water reactor, also went critical at this site, on 15 May 1944. After the war, operations at Site A were moved about 6 miles (9.7 km) to DuPage County , the current location of the Argonne National Laboratory . By December 1942 there were concerns that even Oak Ridge

2160-684: A series of prototype nuclear reactors (or "piles" as Fermi called them) in Pupin Hall at Columbia but were not yet able to achieve a chain reaction. The Advisory Committee on Uranium became the National Defense Research Committee (NDRC) on Uranium when that organization was formed on 27 June 1940. On 28 June 1941, Roosevelt signed Executive Order 8807, which created the Office of Scientific Research and Development (OSRD), under director Vannevar Bush . The office

2280-550: A simpler gun-type design called Little Boy was developed that used uranium-235 . Three methods were employed for uranium enrichment : electromagnetic , gaseous , and thermal . In parallel with the work on uranium was an effort to produce plutonium. After the feasibility of the world's first artificial nuclear reactor, the Chicago Pile-1 , was demonstrated in 1942 at the Metallurgical Laboratory in

2400-592: A special account not subject to the usual auditing and controls was used to hold Trust monies. Between 1944 and his resignation from the Trust in 1947, Groves deposited a total of $ 37.5 million. Groves appreciated the early British atomic research and the British scientists' contributions to the Manhattan Project but stated that the United States would have succeeded without them, although not in time for

2520-516: A state-of-the-art library operated by the city. The city pursues community and economic development and offers housing assistance. The Richland Community Center is adjacent to Howard Amon Park , on the east side of the Columbia River. The building was designed by ARC Architects of Seattle, Washington. Many of its rooms have views of the park and Columbia River, which make it a venue for weddings and receptions, family reunions, birthday parties, business, and community meetings. The rooms are also used for

5400-712: The Army allowed the crops to be harvested, but this was not always possible. The land acquisition process dragged on and was not completed before the end of the Manhattan Project in December 1946. The dispute did not delay work. Although progress on the reactor design at Metallurgical Laboratory and DuPont was not sufficiently advanced to accurately predict the scope of the project, a start was made in April 1943 on facilities for an estimated 25,000 workers, half of whom were expected to live on-site. By July 1944, some 1,200 buildings had been erected and nearly 51,000 people were living in

5520-690: The Army's component the Manhattan District; Reybold officially created this district on 13 August. Informally, it was known as the Manhattan Engineer District, or MED. Unlike other districts, it had no geographic boundaries, and Marshall had the authority of a division engineer. Development of Substitute Materials remained as the official codename of the project as a whole but was supplanted over time by "Manhattan". Marshall later conceded that, "I had never heard of atomic fission but I did know that you could not build much of

5640-625: The August 1945 bombing of Hiroshima. The British wartime participation was crucial to the success of the United Kingdom's independent nuclear weapons program after the war when the McMahon Act of 1946 temporarily ended American nuclear cooperation. The day after he took over the project, Groves went to Tennessee with Colonel Marshall to inspect the proposed site there, and Groves was impressed. On 29 September 1942, United States Under Secretary of War Robert P. Patterson authorized

5760-805: The Australian physicist Mark Oliphant , flew to the US in late August 1941 and discovered that data provided by the MAUD Committee had not reached key American physicists. Oliphant set out to find out why the committee's findings were apparently being ignored. He met with the Uranium Committee and visited Berkeley, California , where he spoke persuasively to Ernest O. Lawrence . Lawrence was sufficiently impressed to commence his own research into uranium. He in turn spoke to James B. Conant , Arthur H. Compton and George B. Pegram . Oliphant's mission

6240-531: The Manhattan Engineer District. One of his first tasks was to move the district headquarters to Oak Ridge, although the name of the district did not change. In September 1943 the administration of community facilities was outsourced to Turner Construction Company through a subsidiary, the Roane-Anderson Company. Chemical engineers were part of "frantic efforts" to make 10% to 12% enriched uranium 235, with tight security and fast approvals for supplies and materials. The population of Oak Ridge soon expanded well beyond

6360-671: The Manhattan Project conducted weapons testing at Bikini Atoll as part of Operation Crossroads , developed new weapons, promoted the development of the network of national laboratories , supported medical research into radiology and laid the foundations for the nuclear navy . It maintained control over American atomic weapons research and production until the formation of the United States Atomic Energy Commission (AEC) in January 1947. The discovery of nuclear fission by Otto Hahn and Fritz Strassmann in 1938, and its theoretical explanation by Lise Meitner and Otto Frisch , made an atomic bomb theoretically possible. There were fears that

For this process, Hugh Taylor of Princeton developed a platinum-on-carbon catalyst for the first three stages while Urey developed a nickel- chromia one for the fourth stage tower. The final cost was $ 2.8 million. The Canadian Government did not officially learn of the project until August 1942. Trail's heavy water production started in January 1944 and continued until 1956. Heavy water from Trail

8400-433: The development of an atomic bomb. In July 1940, Britain had offered to give the United States access to its research, and the Tizard Mission 's John Cockcroft briefed American scientists on British developments. He discovered that the American project was smaller than the British, and not as advanced. As part of the scientific exchange, the MAUD Committee's findings were conveyed to the United States. One of its members,

8520-482: The efficiency of the bomb as it exploded. As the idea of the fission bomb was theoretically settled—at least until more experimental data was available—Edward Teller pushed for discussion of a more powerful bomb: the "super", now usually referred to as a " hydrogen bomb ", which would use the force of a detonating fission bomb to ignite a nuclear fusion reaction in deuterium and tritium . Teller proposed scheme after scheme, but Bethe refused each one. The fusion idea

8640-626: The effort. An agreement between Roosevelt and Churchill known as the Hyde Park Aide-Mémoire , signed in late September 1944, extended the Quebec Agreement to the postwar period and suggested that "when a 'bomb' is finally available, it might perhaps, after mature consideration, be used against the Japanese, who should be warned that this bombardment will be repeated until they surrender". When cooperation resumed after

8760-418: The fall of 1944, the thirty-five working under Oliphant with Lawrence at Berkeley were assigned to existing laboratory groups and most stayed until the end of the war. The nineteen sent to Los Alamos also joined existing groups, primarily related to implosion and bomb assembly, but not the plutonium-related ones. The Quebec Agreement specified that nuclear weapons would not be used against another country without

8880-423: The first mayor of Richland and traveled to Washington, D.C., to negotiate increased rights (such as private home ownership) for citizens in military cities across the country. The U.S. Congress passed a law the following year to mandate the transfer of Richland and Oak Ridge to local control within five years, spurring a new incorporation attempt. The federal government relinquished its land holdings in 1957 and sold

9000-422: The fissile material into a critical mass. The simplest was shooting a "cylindrical plug" into a sphere of "active material" with a "tamper"—dense material to focus neutrons inward and keep the reacting mass together to increase its efficiency. They also explored designs involving spheroids , a primitive form of " implosion " suggested by Richard C. Tolman , and the possibility of autocatalytic methods to increase

9120-579: The general theory of fission reactions, Oppenheimer and Fermi convened meetings at the University of Chicago in June and at the University of California in July 1942 with theoretical physicists Hans Bethe , John Van Vleck , Edward Teller, Emil Konopinski , Robert Serber, Stan Frankel , and Eldred C. (Carlyle) Nelson, and experimental physicists Emilio Segrè , Felix Bloch , Franco Rasetti , Manley, and Edwin McMillan . They tentatively confirmed that

9240-518: The government. Much of the city was planned by Spokane architect Gustav Albin Pherson and overseen by the Army Corps of Engineers. While there were dormitories and barracks built at the time, prefabricated duplexes and single-family homes are all that survive today. Because homes were allocated based on family size and need, there were a number of floorplans available. These were each identified by

9360-401: The head of the Corps of Engineers Construction Division, Major General Thomas M. Robbins , and his deputy, Colonel Leslie Groves . Reybold, Somervell, and Styer decided to call the project "Development of Substitute Materials", but Groves felt that this would draw attention. Since engineer districts normally carried the name of the city where they were located, Marshall and Groves agreed to name

9480-411: The highest rating he could assign was AA-3, although he was willing to provide a AAA rating on request for critical materials if the need arose. Nichols and Marshall were disappointed; AA-3 was the same priority as Nichols' TNT plant in Pennsylvania. Vannevar Bush became dissatisfied with Colonel Marshall's failure to get the project moving forward expeditiously and felt that more aggressive leadership

9600-533: The importance of top priority. Most everything proposed in the Roosevelt administration would have top priority. That would last for about a week or two and then something else would get top priority". One of Groves' early problems was to find a director for Project Y , the group that would design and build the bomb. The obvious choice was one of the three laboratory heads, Urey, Lawrence, or Compton, but they could not be spared. Compton recommended Oppenheimer, who

9720-604: The industrial manufacturing area of Ontario and Quebec, and proximity to a rail head adjacent to a large military base, Camp Petawawa . Located on the Ottawa River, it had access to abundant water. The first director of the new laboratory was Hans von Halban . He was replaced by John Cockcroft in May 1944, who was succeeded by Bennett Lewis in September 1946. A pilot reactor known as ZEEP (zero-energy experimental pile) became

9840-500: The initial plans, and peaked at 75,000 in May 1945, by which time 82,000 people were employed at the Clinton Engineer Works, and 10,000 by Roane-Anderson. The idea of locating Project Y at Oak Ridge was considered, but it was decided that it should be in a remote location. On Oppenheimer's recommendation, the search for a suitable site was narrowed to the vicinity of Albuquerque, New Mexico , where Oppenheimer owned

9960-491: The issues involved in setting up a laboratory in a remote area and should be appointed as its director. Groves personally waived the security requirements and issued Oppenheimer's clearance on 20 July 1943. The British and Americans exchanged nuclear information but did not initially combine their efforts; during 1940-41 the British project ( Tube Alloys ) was larger and more advanced. Britain rebuffed attempts by Bush and Conant in August 1941 to strengthen cooperation because it

10080-535: The land acquisition, which was not completed until March 1945, was only about $ 2.6 million—around $ 47 an acre. When presented with a proclamation declaring Oak Ridge a total exclusion area that no one could enter without military permission, the Governor of Tennessee , Prentice Cooper , angrily tore it up. Initially known as the Kingston Demolition Range, the site was officially renamed

10200-488: The military necessity continues". Wartime land purchases eventually came to 49,383 acres (19,985 ha), but only $ 414,971 was spent. Work commenced in December 1942. Groves initially allocated $ 300,000 for construction, three times Oppenheimer's estimate, but by the time Sundt finished on 30 November 1943, over $ 7 million had been spent. During the war, Los Alamos was referred to as "Site Y" or "the Hill". Initially it

10320-551: The military profile was lower, and physical security elements like high fences and guard dogs were less evident. Canada provided research, extraction and production of uranium and plutonium, and Canadian scientists worked at Los Alamos. Cominco had produced electrolytic hydrogen at Trail, British Columbia , since 1930. Urey suggested in 1941 that it could produce heavy water. To the existing $ 10 million plant consisting of 3,215 cells consuming 75 MW of hydroelectric power, secondary electrolysis cells were added to increase

10440-595: The mutual consent of the US and UK. In June 1945, Wilson agreed that the nuclear bombing of Japan would be recorded as a decision of the Combined Policy Committee. The Combined Policy Committee created the Combined Development Trust in June 1944, with Groves as its chairman, to procure uranium and thorium ores on international markets. The Belgian Congo and Canada held much of the world's uranium outside Eastern Europe, and

10560-403: The necessary resources. The first step was to obtain a high priority rating for the project. The top ratings were AA-1 through AA-4 in descending order, although there was a special AAA rating reserved for emergencies. Ratings AA-1 and AA-2 were for essential weapons and equipment, so Colonel Lucius D. Clay , the deputy chief of staff at Services and Supply for requirements and resources, felt that

10680-543: The old Hanford town site, was closed down. Although many of the workers moved away as the war effort wound down, some of them moved to Richland, offsetting the depopulation that might otherwise have occurred. Management of the Hanford site and Richland itself was transferred to General Electric . Fears that the Soviet Union 's intentions were aggressive set off the Cold War in 1947. The capacity to produce plutonium

10800-406: The population. There were 15,549 households, out of which 34.1% had children under the age of 18 living with them, 56% were married couples living together, 9.3% had a female householder with no husband present, and 31.3% were non-families. 27.2% of all households were made up of individuals, and 9.4% had someone living alone who was 65 years of age or older. The average household size was 2.48 and

10920-443: The population. There were 19,707 households, of which 31.0% had children under the age of 18 living with them, 51.6% were married couples living together, 10.0% had a female householder with no husband present, 4.2% had a male householder with no wife present, and 34.2% were non-families. 28.2% of all households were made up of individuals, and 10.1% had someone living alone who was 65 years of age or older. The average household size

11040-779: The public at large. More recently, the Richland Community Center has hosted several important civic events including the Green Living Awards and the Fall Carnival. As of 2016, the city was planning to rebuild its current city hall across Jadwin Avenue into the parking lot of the United States Federal Courthouse. This decision also includes moving the fire station, which is currently across George Washington Way, to

11160-578: The region. According to Richland's 2021 Comprehensive Annual Financial Report, the top employers in the city are: The Richland School District serves the cities of Richland and West Richland with ten elementary schools, four middle schools, and three high schools. Columbia Basin College , primarily located in Pasco , has a small branch campus in Richland. Washington State University, Tri-Cities , established in North Richland in 1989, sits on

11280-611: The research of Enrico Fermi and others into nuclear chain reactions . They had it signed by Albert Einstein and delivered to President Franklin D. Roosevelt . Roosevelt called on Lyman Briggs of the National Bureau of Standards to head an Advisory Committee on Uranium ; Briggs met with Szilard, Wigner and Edward Teller in October 1939. The committee reported back to Roosevelt in November that uranium "would provide

11400-572: The scale of operations was too great for the area, and it was decided to build the pilot plant at Oak Ridge and keep a research and testing facility in Chicago. Delays in establishing the plant at Argonne led Arthur Compton to authorize the Metallurgical Laboratory to construct the first nuclear reactor beneath the bleachers of Stagg Field at the University of Chicago. The reactor required an enormous amount of highly purified graphite blocks and uranium in both metallic and powdered oxide forms. At

11520-540: The site be located far from the existing uranium production facility at Oak Ridge. In December 1942, Groves dispatched Colonel Franklin Matthias and DuPont engineers to scout potential sites. Matthias reported that Hanford Site near Richland, Washington , was "ideal in virtually all respects". It was isolated and near the Columbia River , which could supply sufficient water to cool the reactors. Groves visited

11640-668: The site in January and established the Hanford Engineer Works (HEW), codenamed "Site W". Under Secretary Patterson gave his approval on 9 February, allocating $ 5 million for the acquisition of 430,000 acres (170,000 ha). The federal government relocated some 1,500 residents of nearby settlements, as well as the Wanapum and other tribes using the area. A dispute arose with farmers over compensation for crops, which had already been planted. Where schedules allowed,

11760-665: The state of Washington—the highest rank achieved in Benton County. As of the 2010 census , there were 48,058 people, 19,707 households, and 12,974 families residing in the city. The population density was 1,345.4 inhabitants per square mile (519.5/km ). There were 20,876 housing units at an average density of 584.4 per square mile (225.6/km ). The racial makeup of the city was 87.0% White , 1.4% African American , 0.8% Native American , 4.7% Asian , 0.1% Pacific Islander , 2.7% from other races , and 3.2% from two or more races. Hispanic or Latino people of any race were 7.8% of

11880-528: The time, there was a limited source of pure uranium metal; Frank Spedding of Iowa State University was able to produce only two short tons . Three short tons was supplied by Westinghouse Lamp Plant , produced in a rush with makeshift process. A large square balloon was constructed by Goodyear Tire to encase the reactor. On 2 December 1942, a team led by Enrico Fermi initiated the first artificial self-sustaining nuclear chain reaction in an experimental reactor known as Chicago Pile-1 . The point at which

12000-496: The two Laser Interferometer Gravitational-Wave Observatory sites is located immediately north of Richland. Numerous smaller high technology business and expert consultants have grown up around the Richland Technology Center as well. Richland is home to the largest cold-storage facility on Earth —which is also one of the largest buildings on Earth by volume . Agriculture is important in the Richland area;

12120-438: The two countries were reversed, and in January 1943 Conant notified the British that they would no longer receive atomic information except in certain areas. The British investigated the possibility of an independent nuclear program but determined that it could not be ready in time to impact the war in Europe . By March 1943 Conant decided that James Chadwick and one or two other British scientists were important enough that

12240-553: The upper end. Three bridges join the trails on both sides, providing several ride options. There are numerous trailheads and access parking spots along the route. Richland lies within a semi-arid, shrub-steppe environment, and has many interesting natural areas within or adjacent to the city: Sports teams in the immediate area include the Tri-City Americans WHL ice hockey team (which plays in Kennewick), and

12360-511: The western bank of the Columbia River. The university offers undergraduate and graduate degree programs. It first admitted freshmen and sophomores in the fall of 2007. There are three 18-hole golf courses and one 9-hole course in the area. Richland has developed a number of parks, several of them fronting the Columbia and Yakima Rivers. The rivers provide boating, water skiing, fishing, kayaking and waterfowl hunting opportunities. Richland

12480-576: Was "pervaded by an atmosphere of enthusiasm and urgency" in the wake of the attack on Pearl Harbor and the United States declaration of war on Japan and on Germany . Work was proceeding on three techniques for isotope separation : Lawrence and his team at the University of California investigated electromagnetic separation , Eger Murphree and Jesse Wakefield Beams 's team looked into gaseous diffusion at Columbia University , and Philip Abelson directed research into thermal diffusion at

12600-399: Was $ 53,092, and the median income for a family was $ 82,354 (Money CNN). Males had a median income of $ 52,648 versus $ 30,472 for females. The per capita income for the city was $ 25,494. About 5.7% of families and 8.2% of the population were below the poverty line , including 10.8% of those under age 18 and 5.6% of those age 65 or over. Manhattan Project The Manhattan Project

12720-437: Was 2.42 and the average family size was 2.97. The median age in the city was 39.4 years. 24.2% of residents were under the age of 18; 8.1% were between the ages of 18 and 24; 24.7% were from 25 to 44; 28.4% were from 45 to 64; and 14.6% were 65 years of age or older. The gender makeup of the city was 49.0% male and 51.0% female. As of the 2000 census , there were 38,708 people, 15,549 households, and 10,682 families residing in

12840-488: Was a research and development program undertaken during World War II to produce the first nuclear weapons . It was led by the United States in collaboration with the United Kingdom and Canada. From 1942 to 1946, the project was directed by Major General Leslie Groves of the U.S. Army Corps of Engineers . Nuclear physicist J. Robert Oppenheimer was the director of the Los Alamos Laboratory that designed

12960-573: Was already intimately familiar with the bomb design concepts. However, Oppenheimer had little administrative experience, and, unlike Urey, Lawrence, and Compton, had not won a Nobel Prize, which many scientists felt that the head of such an important laboratory should have. There were also concerns about Oppenheimer's security status, as many of his associates were communists , including his wife, Kitty ; his girlfriend, Jean Tatlock ; and his brother, Frank . A long conversation in October 1942 convinced Groves and Nichols that Oppenheimer thoroughly understood

13080-572: Was empowered to engage in research and large engineering projects. The NDRC Committee on Uranium became the S-1 Section of the OSRD; the word "uranium" was dropped for security reasons. In July 1941, Briggs proposed spending $ 167,000 on researching uranium, particularly the uranium-235 isotope, and plutonium , which had been isolated for the first time at the University of California in February 1941. In Britain, Frisch and Rudolf Peierls at

13200-537: Was for building and operating the plants that produced the fissile material . Research and production took place at more than 30 sites across the US, the UK, and Canada. The project resulted in two types of atomic bombs, developed concurrently during the war: a relatively simple gun-type fission weapon and a more complex implosion-type nuclear weapon . The Thin Man gun-type design proved impractical to use with plutonium , so

13320-562: Was ideal. Patterson approved the acquisition of the site on 25 November 1942, authorizing $ 440,000 for the purchase of pre-calculated 54,000 acres (22,000 ha), all but 8,900 acres (3,600 ha) of which were already owned by the Federal Government. Secretary of Agriculture Claude R. Wickard granted about 45,000 acres (18,000 ha) of United States Forest Service land to the War Department "for so long as

13440-518: Was increased beginning in 1947. When the Soviet Union developed and tested its first nuclear weapon in 1949, the U.S. nuclear program was reinvigorated. A second post-WWII expansion began in 1950 due to the war in Korea. Richland's Cold War construction boom resulted in Richland's population growing to 27,000 people by 1952. Many of these people lived in a construction camp of trailers located in what

13560-443: Was put aside to concentrate on producing fission bombs. Teller raised the speculative possibility that an atomic bomb might "ignite" the atmosphere because of a hypothetical fusion reaction of nitrogen nuclei. Bethe calculated that it was "extremely unlikely". A postwar report co-authored by Teller concluded that "whatever the temperature to which a section of the atmosphere may be heated, no self-propagating chain of nuclear reactions

13680-637: Was re-incorporated as a city in 1958. For centuries, the village of Chemna stood at the mouth of the current Yakima River. Today that village site is called Columbia Point. From this village, the indigenous Wanapum , Yakama and Walla Walla peoples harvested the salmon runs entering the Yakima River. Captain William Clark of the Lewis and Clark Expedition visited the mouth of the Yakima River on October 17, 1805. In 1904–1905, W.R. Amon and his son Howard purchased 2,300 acres (9 km ) and proposed

13800-408: Was reluctant to share its technological lead and help the United States develop its own atomic bomb. But the British, who had made significant advances in research early in the war, did not have the resources to carry through such a research program into development while a large portion of their economy was engaged in fighting the war; Tube Alloys soon fell behind its American counterpart. The roles of

13920-421: Was required. He spoke to Harvey Bundy and Generals Marshall, Somervell, and Styer about his concerns, advocating that the project be placed under a senior policy committee, with a prestigious officer, preferably Styer, as director. Somervell and Styer selected Groves for the post; General Marshall ordered that he be promoted to brigadier general, as it was felt that the title "general" would hold more sway with

14040-417: Was therefore a success; key American physicists were now aware of the potential power of an atomic bomb. On 9 October 1941, President Roosevelt approved the atomic program after he convened a meeting with Vannevar Bush and Vice President Henry A. Wallace . He created a Top Policy Group consisting of himself—although he never attended a meeting—Wallace, Bush, Conant, Secretary of War Henry L. Stimson , and

14160-476: Was to have been a military laboratory with Oppenheimer and other researchers commissioned into the Army, but Robert Bacher and Isidor Rabi balked at the idea and convinced Oppenheimer that other scientists would object. Conant, Groves, and Oppenheimer then devised a compromise whereby the laboratory was operated by the University of California under contract to the War Department. Dorothy McKibbin ran

14280-410: Was too close to a major population center (Knoxville) in the unlikely event of a major nuclear accident. Groves recruited DuPont in November 1942 to be the prime contractor for the construction of the plutonium production complex. The President of the company, Walter S. Carpenter Jr. , wanted no profit of any kind; for legal reasons a nominal fee of one dollar was agreed upon. DuPont recommended that

14400-533: Was used for Chicago Pile 3 , the first reactor using heavy water and natural uranium, which went critical on 15 May 1944. The Chalk River, Ontario , site was established to rehouse the Allied effort at the Montreal Laboratory away from an urban area. A new community was built at Deep River, Ontario , to provide residences and facilities for the team members. The site was chosen for its proximity to
