Nuclear Security: Better Oversight Needed to Ensure That Security Improvements at Lawrence Livermore National Laboratory Are Fully Implemented and Sustained

摘要

In April 2008, the Department of Energy's (DOE) security inspection at Lawrence Livermore National Laboratory (LLNL) found significant weaknesses, particularly in LLNL's protective force's ability to assure the protection of weapons-grade (special) nuclear material. LLNL is overseen by the National Nuclear Security Administration (NNSA), a separately organized agency within DOE, and managed by a contractor. NNSA is planning to remove most of the special nuclear material from LLNL. GAO was asked to (1) characterize security deficiencies identified in the 2008 inspection; (2) determine the factors that contributed to these deficiencies; (3) identify LLNL's corrective actions to address security deficiencies; and (4) assess LLNL's plan to permanently remove the riskiest special nuclear material from its site. To conduct this work, GAO visited LLNL, reviewed numerous documents and plans, and interviewed LLNL and NNSA security officials. DOE's Office of Independent Oversight found numerous and wide-ranging security deficiencies with LLNL's safeguards and security program. DOE gave the laboratory the lowest possible rating in two security areas: protective force performance and classified matter protection and control.
