National Nuclear Security Administration chief Frank Klotz will visit the Pantex Plant June 17 as his tour across the weapons complex continues. Klotz last week visited the Y-12 National Security Complex, and in May he toured the Nevada National Security Site and Los Alamos and Sandia national laboratories. Confirmed in April, Klotz has yet to visit the Kansas City Plant, Lawrence Livermore National Laboratory, and the Savannah River Site.
