On Friday, October 28, NNSA administrator Lt. Gen. Frank Klotz (Ret.) visited the Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) and received an overview of the lab’s projects supporting NNSA missions. Among these were capabilities in partnership with NNSA and Lawrence Livermore National Laboratory's National Ignition Facility, and an emerging technology that could prove useful in future disarmament agreements, pending the results of further development, testing and evaluation.

Lt. Gen. Frank Klotz (Ret.), NNSA administrator, begins an experiment in zero knowledge protocol, an emerging nuclear warhead verification technology, by pushing a button to activate a neutron generator at PPPL.
