Happy Birthday, Lawrence Livermore National Laboratory! This vital part of the Nuclear Security Enterprise opened #OnThisDay in 1952. llnl.gov/archives/1950s

Over the past two decades, we have partnered with more than 100 countries across the globe to enhance nuclear and radiological security and improve counter nuclear smuggling capabilities. Learn more about #NNSA’s nonproliferation mission: energy.gov/nnsa/nonprolif…

Today we celebrate #NNSA's talented and dedicated team across the Nuclear Security Enterprise. #LaborDay

Blanche J. Lawrence was a research assistant on the #ManhattanProject. After the war, she continued as a biochemist at @Argonne. ahf.nuclearmuseum.org/ahf/profile/bl…

Post-detonation nuclear forensics is key to determining attribution after a nuclear device detonation. Thank you Ashley Hastings, Lawrence Livermore National Laboratory post-doctoral fellow, for presenting your research to the International Nuclear Target Development Society at a Oak Ridge Lab-hosted conference

NNSA is in need of a savvy Program Analyst to plan and prioritize infrastructure programs at #NNSA's sites. #NNSAjobs usajobs.gov/job/806598100

The Los Alamos National Laboratory Machinist Apprentice Program has been around for decades, but was recently revamped and reinvigorated to attract, train, and retain more machinists as the lab broadens its mission and workload. discover.lanl.gov/news/0715-mach…

September 11 has become a #NationalDayofService and Remembrance in America. It's a chance to honor the victims and survivors of 9/11 and give back to our communities. Check out opportunities in your area for next week. americorps.gov/911-day

During the #ManhattanProject, physicist Maria Goeppert-Mayer researched both uranium and the creation of a "super" bomb. After the war, she described the structure of nuclear shells, for which she won the The Nobel Prize in 1963. atomicheritage.org/profile/maria-…

#DYK the #FBI can pull forensics and identifiable info from weapons of mass destruction (WMD)? Recently, members of our Laboratory Division trained alongside @NNSAnews in the “Diamond Thunder” exercise—locating, securing, and disassembling a prop WMD for forensics.

In September 1942, Col. Leslie Groves -- he wasn't a general yet -- selected Oak Ridge, Tennessee, as the site of what would become Y-12 NSC. He had the government buy Site X -- 52,000 acres of land on the Clinch River. #ManhattanProject

A key #nonproliferation mission is taking nuclear material that terrorists or other bad actors could use out of their reach. Over the years, #NNSA and its predecessor agencies have done a pretty good job of removing it!

At peak production during the #ManhattanProject, there were around 22,000 employees at Y-12 NSC. Approximately half of those workers were young women. Originally known as cubicle operators, these "Calutron girls" operated the machines used to separate uranium for Little Boy. #TBT

A new electrochemical method developed by a team at Lawrence Livermore National Laboratory could make chemical production cleaner and more energy-efficient. 🧪👩‍🔬🏭 llnl.gov/article/51591/…
