Department of Energy: National Security Controls Over Contractors Traveling to Foreign Countries Need Strengthening, Report to Congressional Requesters [open pdf - 516KB]
Department of Energy (DOE) has established various national security controls for foreign travel to guard against foreign intelligence interests' obtaining information that would be detrimental to U.S. security or business. In this report, the GAO (1) describes the types of foreign-intelligence-gathering incidents that have occurred during foreign travel by contractor employees, (2) discusses the DOE controls that apply to foreign travel by contractor employees, and (3) identifies areas where these controls can be strengthened. It focuses on official business travel by contractors at four of DOE's nine national laboratories: Lawrence Livermore in California, Los Alamos in New Mexico, Oak Ridge in Tennessee, and Sandia in New Mexico. Livermore, Los Alamos, and Sandia make up DOE's nuclear weapons laboratories. Oak Ridge was included to provide a broader perspective to our work.
