Gen. Frank Klotz, Under Secretary for Nuclear Security and NNSA Administrator, earlier this week toured the Nevada National Security Site (NNSS) and met with employees. During the tour, Gen. Klotz visited the Device Assembly Facility (DAF), which offers one of the safest, most secure locations anywhere in the U.S. weapons complex to conduct nuclear explosive operations. Scientists at DAF work on special nuclear material, radiation test objects, and high-explosives in support of experiments for Stockpile Stewardship and other programs.
Klotz also toured the U1a Complex which is an underground laboratory used for subcritical experiments and physics experiments that obtain technical information about the nation’s nuclear weapons stockpile. These experiments support NNSA’s Stockpile Stewardship Programs, created to maintain the safety and effectiveness of the U.S. nuclear weapons stockpile.
Below, Klotz listens to a briefing 960 feet underground in the U1a complex at the Nevada National Security Complex. Leading the briefing are (left to right): Stuart Rawlinson, facility manager for the U1a complex, and Raffi Papazian, director of Defense Experimentation and Stockpile Stewardship, both from National Security Technologies.
