Plutonium research to advance stockpile safely

Aug. 29, 2017- 
Conducting an experiment that combines high explosives with plutonium -- a special nuclear material used in nuclear weapons -- is no trivial matter. Not only do researchers need to ensure the plutonium remains "subcritical" to avoid a nuclear explosion, they must be absolutely certain that these materials are confined in a worst-case scenario. On top of that, they have to be sure they can...

LLNL supports ICBM flight tests

June 5, 2017- 
As an unarmed Minuteman III intercontinental ballistic missile (ICBM) rocketed into the night sky, a team of Lawrence Livermore National Laboratory (LLNL) researchers listened intently to radio chatter and watched flight data stream in from a control room at the Ronald Reagan Ballistic Missile Defense Test Site. It was the first of two flight tests conducted recently to verify that the system...

How this Martian moon became the 'Death Star'

Oct. 12, 2016- 
Mars’ largest moon, Phobos, has captured public imagination and been shrouded in mystery for decades. But numerical simulations recently conducted at Lawrence Livermore National Laboratory (LLNL) have shed some light on the enigmatic satellite. The dominant feature on the surface of Phobos (22-kilomters across) is Stickney crater (9-km across), a mega crater that spans nearly half the moon...

60 years of service to the nation

Dec. 17, 2015- 
After finishing his education in physics at Sacramento State, Dan Patterson applied at Lawrence Livermore National Laboratory at the recommendation of his adviser. As part of his interview, he worked on a few physics problems and filled out paperwork for a potential clearance. Six weeks later, he finally got a call asking him to report to work.  It was 1955. Little did he know, that first day...

Event honors 20 years of Stockpile Stewardship

Oct. 22, 2015- 
The proven success of the Stockpile Stewardship Program (SSP) – which pushed the limits of modern science and engineering by requiring the transition from explosive nuclear weapons testing to what is effectively virtual nuclear testing – was celebrated Wednesday at a half-day public event hosted by the Department of Energy’s National Nuclear Security Administration (NNSA).Featured speakers...

Labs tap Silicon Valley to bolster computing

The National Nuclear Security Administration’s (NNSA’s) Lawrence Livermore National Laboratory today announced the awarding of a subcontract to Penguin Computing — a leading developer of high-performance Linux cluster computing systems based in Silicon Valley — to bolster computing for stockpile stewardship at its three national security laboratories. Under the terms of the contract, awarded...

From grassland to 21st century science

Sept. 25, 2015- 
Sixty years ago, the UC Radiation Laboratory began testing high explosives at what would become one of the nation’s most sophisticated non-nuclear weapons testing sites, an 11 square-mile plot of rural grassland tucked away in the steep ravines and tawny rolling hills near the Alameda-San Joaquin County line.On Thursday, Site 300 celebrated its 60th anniversary, with a picnic attended by more...

National Ignition Facility fires 300th shot in FY15

Aug. 18, 2015- 
Last week, the National Ignition Facility (NIF) fired its 300th laser target shot in fiscal year (FY) 2015, meeting the year’s goal more than six weeks early. In comparison, the facility completed 191 target shots in FY 2014. Located at Lawrence Livermore National Laboratory (LLNL), the NIF is the world’s most energetic laser.Increasing the shot rate has been a top priority for the Inertial...
