Nuclear Power Plants: Efforts Made to Upgrade Security, but the Nuclear Regulatory Commission's Design Basis Threat Process Should Be Improved

A letter report issued by the Government Accountability Office with an abstract that begins "The nation's commercial nuclear power plants are potential targets for terrorists seeking to cause the release of radioactive material. The Nuclear Regulatory Commission (NRC), an independent agency headed by five commissioners, is responsible for regulating and overseeing security at the plants. In April 2003, in response to the terrorist attacks of September 11, 2001, NRC revised the design basis threat (DBT), which describes the threat that plants must be prepared to defend against in terms of the number of attackers and their training, weapons, and tactics. NRC has also restructured its program for testing security at the plants through force-on-force inspections, which consist of mock terrorist attacks. GAO was asked to review (1) the process NRC used to revise the DBT for nuclear power plants, (2) the actions nuclear power plants have taken to enhance security in response to the revised DBT, and (3) NRC's progress in strengthening the conduct of force-on-force inspections at the plants.
