Accountability Office,[2009]ii, 36 pages digital, PDF fileTitle from title screen (viewed on Apr. 16, 2009)."March 2009.""GAO-09-321."Includes bibliographical references.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.Nuclear security Nuclear facilitiesSecurity measuresUnited StatesNuclear energyResearchLaboratoriesSecurity measuresUnited StatesNational securityUnited StatesNuclear facilitiesSecurity measuresNuclear energyResearchLaboratoriesSecurity measuresNational securityDIDDIDGPOBOOK9910698803803321Nuclear security3171215UNINA
