May 24, 2019- 
Lawrence Livermore National Laboratory (LLNL) successfully executed its first subcritical experiment since 2003 on Feb. 13 at the Nevada National Security Site (NNSS) U1a facility. The experiment — dubbed "Ediza" — took place deep below the desert floor and was the culmination of a five-year campaign aimed at capturing high-fidelity plutonium data in support of nuclear stockpile safety. Subc...

NARAC marks 40 years of emergency response

April 4, 2019- 
It’s been 40 years since the first emergency phone call came in from the Department of Energy to Lawrence Livermore National Laboratory (LLNL). An accident had occurred at the Three Mile Island nuclear power plant on March 28, 1979 that led to a release of radioactivity into the atmosphere. This is how the National Atmospheric Release Advisory Center (NARAC) was born. Over the next 10 days,...

Uncovering secret structure to safer explosives

Oct. 17, 2018- 
A team of scientists at Lawrence Livermore National Laboratory (LLNL) has shown that the structure of microscopic pores in high explosive materials can significantly impact performance and safety. These findings --  published recently as the cover article in the journal Propellants, Explosives, Pyrotechnics --  open the door to the possibility of tuning high explosives by engineering their...

Theory aids analysis of nuclear materials

Aug. 22, 2018- 
Nuclear emergency teams, safeguards specialists and others may one day benefit from an expanded nuclear fission chain theory and detectors developed by a team of Lawrence Livermore Nationla Laboratory (LLNL) physicists.          The Livermore scientists have bolstered their theory for understanding nuclear fission chains --  a cascade of atomic nuclei splitting, each initiated by a neutron...

LLNL-led team expands forensic method to identify people using proteins from bones

May 21, 2018- 
When a team of researchers led by Lawrence Livermore National Laboratory (LLNL) developed a new biological identification method that exploits information encoded in proteins, they thought it could have multiple applications. Nearly two years later, they’ve turned out to be right. In September 2016, LLNL scientists announced they had developed a science-based, statistically validated way to...

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...
