Simulating nuclear cloud rise anywhere, anytime

For decades, understanding the behavior of a nuclear mushroom cloud was done with careful analysis of observations made during the testing era. Old photos, outdated film and incomplete weather data made precise calculations difficult. Now, with results published in Atmospheric Environment, Lawrence Livermore National Laboratory (LLNL) scientists are improving our…

LLNL earn 'A' grade in OPCW biomedical proficiency test

It wasn’t an easy road, but Lawrence Livermore National Laboratory (LLNL) Forensic Science Center scientists earned an “A” grade in the Organisation for the Prohibition of Chemical Weapons’ (OPCW) recent biomedical proficiency test. In addition to the usual complexity of the sample preparations and analysis, the Livermore scientists received their proficiency test samples…

Bradley Wallin selected to lead Weapons and Complex Integration

Bradley Wallin has been named Lawrence Livermore National Laboratory’s (LLNL’s) principal associate director (PAD) for Weapons and Complex Integration (WCI), Lab Director Kimberly Budil announced today.

LLNL hosts Test Site Verification Team orientation

Lawrence Livermore National Laboratory (LLNL) hosted an in-person orientation meeting recently for members of the National Nuclear Security Administration’s (NNSA) Test Site Verification Team (TSVT). TSVT is sponsored by NNSA’s Office of Nuclear Verification (ONV) Nuclear Compliance Verification (NCV) Program. The TSVT is led by Kim Knight from LLNL and Emily Schultz…

LLNL's Forensic Science Center earns 'A' grade in OPCW environmental test

This fall, a score of scientists from Lawrence Livermore National Laboratory's (LLNL) Forensic Science Center (FSC) will start two weeks of long days to undertake the Organisation for the Prohibition of Chemical Weapons (OPCW) environmental proficiency test. Livermore scientists have been taking the proficiency tests each October since 2001, with LLNL serving as one of two…

LLNL and KCNSC team up to accelerate design-to-deployment with new polymer production enclave

A polymer production enclave, in partnership with the Kansas City National Security Campus (KCNSC) and Lawrence Livermore National Laboratory (LLNL), is on budget and on schedule to bring modern technology into the Nuclear Security Enterprise. The enclave will enable rapid development of design and production processes of polymer parts for modernization programs. This…

LLNL team conducts thermal, shock, vibration tests on W80-4 mock unit

A Lawrence Livermore National Laboratory (LLNL) team has conducted the first series of combined environment ground tests on a W80-4 test article to ensure that the warhead will survive thermal, shock and vibration environments that the system could be exposed to when it is in the stockpile. The Nuclear Explosive Package Engineering Test (NEPET), which began with a…

Army reservists a vital part of Lab’s workforce

Lawrence Livermore National Laboratory (LLNL) joins in the celebration of the U.S. Army birthday on June 14. Created in 1775, the army originally consisted of volunteer soldiers with roots to the Continental Army — and was formed to fight the Revolutionary War. Today, as the largest branch of the country’s military, the proud men and women of the U.S. Army continue to…

Different neutron energies enhance asteroid deflection

A research collaboration between Lawrence Livermore National Laboratory (LLNL) and the Air Force Institute of Technology (AFIT) investigates how the neutron energy output from a nuclear device detonation can affect the deflection of an asteroid. Scientists compared the resulting asteroid deflection from two different neutron energy sources, representative of fission and…

Ten-year anniversary of Fukushima observed

Ten years ago today, on March 11, 2011, a 9.0 Richter-scale earthquake and tsunami in Japan resulted in severe damage to the Fukushima Dai-ichi nuclear power plant and also led to releases of radioactivity into the environment. That same day, the U.S. Department of Energy (DOE) activated Lawrence Livermore National Laboratory’s National Atmospheric Release Advisory Center …

LLNL and NPS ink MOU for collaboration

Whether working informally or through a collaboration agreement, Lawrence Livermore National Laboratory (LLNL) and the Monterey-based Naval Postgraduate School (NPS) have enjoyed an enduring relationship for more than two decades. While the two institutions have worked together informally for years, until recently they had only one memorandum of understanding (MOU)…

Lab-designed instrumentation onboard unarmed missile

A joint test assembly (JTA) designed by Lawrence Livermore and Sandia national laboratories was recently onboard an unarmed Minuteman III intercontinental ballistic missile (ICBM), which was successfully launched from Vandenberg Air Force Base in California. See the video. The purpose of the ICBM test launch program is to validate and verify the safety, security,…

LLNL’s Tringe provides final OK for Minuteman launch

Col. Joe Tringe, a group leader at Lawrence Livermore National Laboratory (LLNL) and an Air Force reservist, served as the final decision authority during the recent successful unarmed Minuteman III intercontinental ballistic missile launched from Vandenberg Air Force Base in California. See the video. As launch decision authority, Tringe worked closely with the mission…

LLNL’s Charles and Debbie Ball receive Secretary of Defense Medal for Exceptional Public Service

Lawrence Livermore National Laboratory's (LLNL's) Charles and Debbie Ball have received the Office of the Secretary of Defense (OSD) Medal for Exceptional Public Service while on assignment with OSD. The medal is presented by the secretary of Defense to non-career federal employees, private citizens and foreign nationals. The citation noted that Charles Ball made…
