The W91 was an American thermonuclear warhead intended for use on the SRAM-T variant of the AGM-131 SRAM II air to ground missile.
51-645: What was to become the W91 design entered into a Phase 2 design competition between the various nuclear weapons laboratories in November 1988. Further development details are somewhat unclear, but a Los Alamos National Laboratory design won the competition. The design that emerged had a weight of 310 pounds (140 kg), with a two selectable yields of 10 or 100 kilotonnes of TNT (42 or 418 TJ). Other physical characteristics have not been well described in public documents. The design has been described as being named
102-451: A Department of Energy investigation into the laboratory. The investigation found that the "missing plutonium" was a result of miscalculation by LANL's statisticians and did not actually exist; but the investigation did lead to heavy criticism of the laboratory by the DOE for security flaws and weaknesses that the DOE claimed to have found. LANL is northern New Mexico's largest institution and
153-551: A drum containing nuclear waste was ruptured due to a ' deflagration ' according to an inspector general report of the Dept. of Energy, which due to lab mistakes, also occurred in 2014 at the Carlsbad plant with significant disruptions and costs across the industry. In 2009, 69 computers which did not contain classified information were lost. The same year also saw a scare in which 1 kg (2.2 lb) of missing plutonium prompted

Best known for its central role in helping develop
357-459: A photo nearly led to a criticality incident. The photo shoot, which was directed by the laboratory's management, was one of several factors relating to unsafe management practices that led to the departure of 12 of the lab's 14 safety staff. The criticality incident was one of several that led the Department of Energy to seek alternative bids to manage the laboratory after the 2018 expiration of

After the war, Oppenheimer retired from the directorship, and it was taken over by Norris Bradbury , whose initial mission was to make the previously hand-assembled atomic bombs "G.I. proof" so that they could be mass-produced and used without the assistance of highly trained scientists. Other founding members of Los Alamos left

"These vaccines might finally deal a lethal blow to the AIDS virus ", says Chang-Shung Tung, leader of the Lab's Theoretical Biology and Biophysics group. The laboratory has attracted negative publicity from a number of events. In 1999, Los Alamos scientist Wen Ho Lee was accused of 59 counts of mishandling classified information by downloading nuclear secrets—"weapons codes" used for computer simulations of nuclear weapons tests—to data tapes and removing them from
816-511: The Lawrence Livermore National Laboratory (LLNL). The two labs competed on a wide variety of bomb designs, but with the end of the Cold War , have focused increasingly on civilian missions. Today, Los Alamos conducts multidisciplinary research in fields such as national security , space exploration , nuclear fusion , renewable energy , medicine , nanotechnology , and supercomputing . While owned by

Los Alamos was established in 1943 as Project Y , a top-secret site for designing nuclear weapons under the Manhattan Project during World War II . Chosen for its remote yet relatively accessible location, it served as the main hub for conducting and coordinating nuclear research, bringing together scientists from around
1020-517: The flow cytometry technology. In the 1950s, researcher Mack Fulwyler developed a technique for sorting erythrocytes that combined the Coulter Principle of Coulter counter technologies, which measures the presence of cells and their size, with ink jet technology, which produces a laminar flow of liquid that breaks up into separate, fine drops. In 1969, Los Alamos reported the first fluorescence detector apparatus, which accurately measured
1071-519: The "New Mexico 1" code name, and as using TATB based insensitive plastic bonded explosive and a fire-resistant nuclear fissile material core or pit . The design was cancelled in September 1991 along with the SRAM T missile, prior to production of any units, though some test devices may have been manufactured. Notably, the W91 was the last new US nuclear weapon design to reach the point of receiving

On June 8, 2018, the NNSA announced that Triad National Security, LLC, a joint venture between Battelle Memorial Institute , the University of California, and Texas A&M University, would assume operation and management of LANL beginning November 1, 2018. In August 2011, the close placement of eight plutonium rods for
1224-599: The LANS contract. The lab was penalized with a $ 57 million reduction in its 2014 budget over the February 14, 2014, accident at the Waste Isolation Pilot Plant for which it was partly responsible. In August 2017, the improper storage of plutonium metal could have triggered a criticality accident , and subsequently staff failed to declare the failure as required by procedure. With support of
1275-524: The Manhattan Project, Los Alamos hosted thousands of employees, including many Nobel Prize -winning scientists. The location was a total secret. Its only mailing address was a post office box, number 1663, in Santa Fe , New Mexico. Eventually two other post office boxes were used, 180 and 1539, also in Santa Fe. Though its contract with the University of California was initially intended to be temporary,
1326-522: The Secretary-Treasurer Robert Underhill, who was in charge of wartime contracts and liabilities. The work of the laboratory culminated in several atomic devices, one of which was used in the first nuclear test near Alamogordo, New Mexico , codenamed " Trinity ", on July 16, 1945. The other two were weapons, " Little Boy " and " Fat Man ", which were used in the attacks on Hiroshima and Nagasaki. The Laboratory received
1377-490: The country indicated the need for a laboratory dedicated solely to that purpose. General Leslie Groves wanted a central laboratory at an isolated location for safety, and to keep the scientists away from the populace. It should be at least 200 miles from international boundaries and west of the Mississippi. Major John Dudley suggested Oak City, Utah , or Jemez Springs, New Mexico , but both were rejected. Jemez Springs

Robert "Bob" Beyster left Los Alamos to work for General Atomics (GA) in San Diego . Three major nuclear-related accidents have occurred at LANL. Criticality accidents occurred in August 1945 and May 1946, and
1479-467: The current Pueblo of Jemez . In the nineteenth century the valley was given over to mostly agrarian and pastoral uses. Jemez Springs' post office opened in 1907. The village is named for the Pueblo of Jemez twelve miles to the south. The 1907 post office was preceded by one established in 1884 named Archuleta . The village's current main bathhouse originates from this period. In 1942, Jemez Springs

In 2008, development for a safer, more comfortable and accurate test for breast cancer was ongoing by scientists Lianjie Huang and Kenneth M. Hanson and collaborators. The new technique, called ultrasound-computed tomography (ultrasound CT), uses sound waves to accurately detect small tumors that traditional mammography cannot. The lab has made intense efforts for humanitarian causes through its scientific research in medicine. In 2010, three vaccines for
1581-402: The environment. It also contributed to thousands of dumpsites at 108 locations in 29 US states. Continuing efforts to make the laboratory more efficient led the Department of Energy to open its contract with the University of California to bids from other vendors in 2003.

In 1952, Lawrence Livermore National Laboratory was founded to act as Los Alamos' "competitor", with the hope that two laboratories for the design of nuclear weapons would spur innovation. Los Alamos and Livermore served as the primary classified laboratories in the U.S. national laboratory system, designing all
