Los Alamos National Laboratory

The laboratory was founded during World War II as a secret, centralized facility to coordinate the scientific research of the Manhattan Project, the Allied project to develop the first nuclear weapons. In September 1942, the difficulties encountered in conducting preliminary studies on nuclear weapons at universities scattered across 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 was only a short distance from the current site. Project Y director J. Robert Oppenheimer had spent much time in his youth in the New Mexico area, and suggested the Los Alamos Ranch School on the mesa. Dudley had rejected the school as not meeting Groves’ criteria, but as soon as Groves saw it he said in effect "This is the place".[11] Oppenheimer became the laboratory's first director.

During 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.[12] Though its contract with the University of California was initially intended to be temporary, the relationship was maintained long after the war. Until the atomic bombings of Hiroshima and Nagasaki, Japan, University of California president Robert Sproul did not know what the purpose of the laboratory was and thought it might be producing a "death ray".[13] The only member of the UC administration who knew its true purpose—indeed, the only one who knew its exact physical location—was the Secretary-Treasurer Robert Underhill, who was in charge of wartime contracts and liabilities.

The first stages of the explosion of the Trinity nuclear test.

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 the Army-Navy ‘E’ Award for Excellence in production on October 16, 1945.

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. Many of the original Los Alamos "luminaries" chose to leave the laboratory, and some even became outspoken opponents to the further development of nuclear weapons.

The name officially changed to the Los Alamos Scientific Laboratory on January 1, 1947. By this time, Argonne had already been made the first National Laboratory the previous year. Los Alamos would not become a National Laboratory in name until 1981.[14]

In the years since the 1940s, Los Alamos was responsible for the development of the hydrogen bomb, and many other variants of nuclear weapons. 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 the country's nuclear arsenal. Additional work included basic scientific research, particle accelerator development, health physics, and fusion power research as part of Project Sherwood. Many nuclear tests were undertaken in the Marshall Islands and at the Nevada Test Site. During the late-1950s, a number of scientists including Dr. J. Robert "Bob" Beyster left Los Alamos to work for General Atomics (GA) in San Diego.[15]

Three major nuclear-related accidents have occurred at LANL. Criticality accidents occurred in August 1945 and May 1946, and a third accident occurred during an annual physical inventory in December 1958.[16]

Several buildings associated with the Manhattan Project at Los Alamos were declared a National Historic Landmark in 1965.[4][17]

At the end of the Cold War, both labs went through a process of intense scientific diversification in their research programs to adapt to the changing political conditions that no longer required as much research towards developing new nuclear weapons and has led the lab to increase research for "non-war" science and technology. Los Alamos' nuclear work is currently thought to relate primarily to computer simulations and stockpile stewardship. The development of the Dual-Axis Radiographic Hydrodynamic Test Facility will allow complex simulations of nuclear tests to take place without full explosive yields.

The laboratory contributed to the early development of 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 the number and size of ovarian cells and blood cells.[18]

As of 2017, other research performed at the lab included developing cheaper, cleaner bio-fuels and advancing scientific understanding around renewable energy.[19]

Non-nuclear national security and defense development is also a priority at the lab. This includes preventing outbreaks of deadly diseases by improving detection tools and the monitoring the effectiveness of the United States’ vaccine distribution infrastructure. Additional advancements include the ASPECT airplane that can detect bio threats from the sky.[20]

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.[21]

The lab has made intense efforts for humanitarian causes through its scientific research in medicine. In 2010, three vaccines for the Human Immunodeficiency Virus were being tested by lab scientist Bette Korber and her team. "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.[22]

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 the lab. After ten months in jail, Lee pleaded guilty to a single count and the other 58 were dismissed with an apology from U.S. District Judge James Parker for his incarceration.[23] Lee had been suspected for having shared U.S. nuclear secrets with China, but investigators were never able to establish what Lee did with the downloaded data.[24] In 2000, two computer hard drives containing classified data were announced to have gone missing from a secure area within the laboratory, but were later found behind a photocopier.[25]

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. Though the university and the laboratory had difficult relations many times since their first World War II contract, this was the first time that the university ever had to compete for management of the laboratory. The University of California decided to create a private company with the Bechtel Corporation, Washington Group International, and the BWX Technologies to bid on the contract to operate the laboratory. The UC/Bechtel led corporation—Los Alamos National Security, LLC (LANS)—was pitted against a team formed by the University of Texas System partnered with Lockheed-Martin. In December 2005, the Department of Energy announced that LANS had won the next seven-year contract to manage and operate the laboratory.

On June 1, 2006, the University of California ended its sixty years of direct involvement in operating Los Alamos National Laboratory, and management control of the laboratory was taken over by Los Alamos National Security, LLC with effect October 1, 2007. Approximately 95% of the former 10,000 plus UC employees at LANL were rehired by LANS to continue working at LANL. Other than UC appointing three members to the eleven member board of directors that oversees LANS, UC now has virtually no responsibility or direct involvement in LANL. UC policies and regulations that apply to UC campuses and its two national laboratories in California (Lawrence Berkeley and Lawrence Livermore) no longer apply to LANL, and the LANL director no longer reports to the UC Regents or UC Office of the President. Also, LANL employees were removed from the UC's 403(b) retirement savings and defined benefits pension program and placed in a LANS run program. While the LANS retirement program provides rehired UC employees with pensions similar to those UC would have given them, LANS no longer guarantees full pensions to newly hired LANL employees. It now provides basic 401(k) retirement saving options.

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.[32]

In August 2011, a near criticality incident happened with eight rods of plutonium placed close to each other to take a photo. In the aftermath, 12 of 14 of the lab's safety staff left in anger about their advice being dismissed by the management. Without safety management, the Plutonium Facility PF-4 was shut down in 2013 and is still closed in 2017 because the lab fails to meet expectations.[33] As a consequence, the U.S. Department of Energy, sought alternative suppliers the LANL's management contract.[34]

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.[35]

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.[34][36]
