Lawrence Livermore National Laboratory
Lawrence Livermore National Laboratory is a federally funded research and development center in Livermore, California, United States. Established in 1952, the laboratory is sponsored by the United States Department of Energy and administered privately by Lawrence Livermore National Security, LLC.
The lab was originally established as the University of California Radiation Laboratory, Livermore Branch in 1952 in response to the detonation of the Soviet Union's first atomic bomb during the Cold War. It later became autonomous in 1971 and was designated a national laboratory in 1981.
Lawrence Livermore Lab is primarily funded by the U.S. Department of Energy and it is managed privately and operated by Lawrence Livermore National Security, LLC. In 2012, the synthetic chemical element livermorium first made in year 2000, was named after the laboratory.
The Livermore facility was co-founded by Edward Teller and Ernest Lawrence, then director of the Radiation Laboratory at Berkeley.
Overview
LLNL is a research and development institution for science and technology applied to national security. Its principal responsibility is ensuring the safety, security and reliability of the nation's nuclear weapons through the application of advanced science, engineering, and technology. The laboratory also applies its special expertise and multidisciplinary capabilities towards preventing the proliferation and use of weapons of mass destruction, bolstering homeland security, and solving other nationally important problems, including energy and environmental needs, scientific research and outreach, and economic competitiveness.The laboratory is located on a site at the eastern edge of Livermore. It also operates a remote experimental test site known as Site 300, situated about southeast of the main lab site. LLNL has an annual budget of about $3.25 billion and a staff of nearly 10,000 employees.
History
Origins
LLNL was established in 1952, as the University of California Radiation Laboratory, Livermore Branch, an offshoot of the existing University of California Radiation Laboratory at Berkeley. The lab at Livermore was intended to spur innovation and provide competition to the nuclear weapon design laboratory at Los Alamos in New Mexico, home of the Manhattan Project that developed the first atomic weapons. The Livermore facility was co-founded by Edward Teller and Ernest Lawrence, director of the Radiation Laboratory at Berkeley.The new laboratory was sited at a former naval air station from World War II. It was already home to several University of California Radiation Laboratory projects that were too large for its location in the Berkeley Hills above the UC campus, including one of the first experiments in the magnetic approach to confined thermonuclear reactions. About half an hour southeast of Berkeley, the Livermore site provided much greater security for classified projects than an urban university campus.
Lawrence tapped his former graduate student Herbert York, age 32, to run Livermore. Under York, the Lab had four main programs: Project Sherwood, Project Whitney, diagnostic weapon experiments, and a basic physics program. York and the new lab embraced the Lawrence "big science" approach, tackling challenging projects with physicists, chemists, engineers, and computational scientists working together in multidisciplinary teams. Lawrence died in August 1958 and shortly after, the university's board of regents named both laboratories for him, as the Lawrence Radiation Laboratory.
Historically, the Berkeley and Livermore laboratories have had very close relationships on research projects, business operations, and staff. The Livermore Lab was established initially as a branch of the Berkeley laboratory. The Livermore lab was not officially severed administratively from the Berkeley lab until 1971. To this day, in official planning documents and records, Lawrence Berkeley National Laboratory is designated as Site 100, Lawrence Livermore National Lab as Site 200, and LLNL's remote test location as Site 300.
Renaming
The laboratory was renamed Lawrence Livermore Laboratory in 1971. On October 1, 2007 Lawrence Livermore National Security, LLC assumed management of LLNL from the University of California, which had exclusively managed and operated the Laboratory since its inception 55 years before. The laboratory was honored in 2012 by having the synthetic chemical element livermorium named after it.The LLNS takeover of the laboratory has been controversial. In May 2013, an Alameda County jury awarded over $2.7 million to five former laboratory employees who were among 430 employees LLNS laid off during 2008. The jury found that LLNS breached a contractual obligation to terminate the employees only for "reasonable cause." The five plaintiffs also have pending age discrimination claims against LLNS, which will be heard by a different jury in a separate trial. There are 125 co-plaintiffs awaiting trial on similar claims against LLNS. The May 2008 layoff was the first layoff at the laboratory in nearly 40 years.
On March 14, 2011, the City of Livermore officially expanded the city's boundaries to annex LLNL and move it within the city limits. The unanimous vote by the Livermore city council expanded Livermore's southeastern boundaries to cover 15 land parcels covering that comprise the LLNL site. The site was formerly an unincorporated area of Alameda County. The LLNL campus continues to be owned by the federal government.
Major projects
Nuclear weapons
From its inception, Livermore focused on new weapon design concepts; as a result, its first three nuclear tests were unsuccessful. The lab persevered and its subsequent designs proved increasingly successful. In 1957, the Livermore Lab was selected to develop the warhead for the Navy's Polaris missile. This warhead required numerous innovations to fit a nuclear warhead into the relatively small confines of the missile nosecone.During the Cold War, many Livermore-designed warheads entered service. These were used in missiles ranging in size from the Lance surface-to-surface tactical missile to the megaton-class Spartan antiballistic missile. Over the years, LLNL designed the warheads: W27, W38, B41, W45, W47, W48, W55, W56, W58, W62, W68, W70, W71, W79, W82, B83, and W87. The W87 and the B83 are the only LLNL designs still in the U.S. nuclear stockpile.
With the collapse of the Soviet Union in 1991 and the end of the Cold War, the United States began a moratorium on nuclear testing and development of new nuclear weapon designs. To sustain existing warheads for the indefinite future, a science-based Stockpile Stewardship Program was defined that emphasized the development and application of greatly improved technical capabilities to assess the safety, security, and reliability of existing nuclear warheads without the use of nuclear testing. Confidence in the performance of weapons, without nuclear testing, is maintained through an ongoing process of stockpile surveillance, assessment and certification, and refurbishment or weapon replacement.
With no new designs of nuclear weapons, the warheads in the U.S. stockpile must continue to function far past their original expected lifetimes. As components and materials age, problems can arise. Stockpile Life Extension Programs can extend system lifetimes, but they also can introduce performance uncertainties and require maintenance of outdated technologies and materials. Because there is concern that it will become increasingly difficult to maintain high confidence in the warheads for the long term, the Department of Energy/National Nuclear Security Administration initiated the Reliable Replacement Warhead Program. RRW designs could reduce uncertainties, ease maintenance demands, and enhance safety and security. In March 2007, the LLNL design was chosen for the Reliable Replacement Warhead. Since that time, Congress has not allocated funding for any further development of the RRW.
Plutonium research
LLNL conducts research into the properties and behavior of plutonium to learn how plutonium performs as it ages and how it behaves under high pressure. Plutonium has seven temperature-dependent solid allotropes. Each possesses a different density and crystal structure. Alloys of plutonium are even more complex; multiple phases can be present in a sample at any given time. Experiments are conducted at LLNL and elsewhere to measure the structural, electrical and chemical properties of plutonium and its alloys and to determine how these materials change over time. Such measurements enable scientists to better model and predict plutonium's long-term behavior in the aging stockpile.The Lab's plutonium research is conducted in a specially designed facility called the SuperBlock, with emphasis on safety and security. Work with highly enriched uranium is also conducted there. In March 2008, the National Nuclear Security Administration presented its preferred alternative for the transformation of the nation's nuclear weapons complex. Under this plan, LLNL would be a center of excellence for nuclear design and engineering, a center of excellence for high explosive research and development, and a science magnet in high-energy-density physics. In addition, most of its special nuclear material would be removed and consolidated at a more central, yet-to-be-named site.
On September 30, 2009, the NNSA announced that about two thirds of the special nuclear material at LLNL requiring the highest level of security protection had been removed from LLNL. The move was part of NNSA's efforts initiated in October 2006 to consolidate special nuclear material at five sites by 2012, with significantly reduced square footage at those sites by 2017. The federally mandated project intended to improve security and reduce security costs, as part of NNSA's overall effort to transform the Cold War era "nuclear weapons" enterprise into a 21st-century "nuclear security" enterprise. The original date to remove all high-security nuclear material from LLNL, based on equipment capability and capacity, was 2014. NNSA and LLNL then developed a timeline to remove this material earlier, and accelerated the completion date to 2012.
