Two bills that would have required enhanced security at nuclear power plants were introduced in the 108th Congress but neither was approved. S. 1043 would have required that the government classify threats against power plants; coordinate federal, state, and local security efforts; review the adequacy of existing security plans; and revise hiring and training standards for private security officers serving at nuclear power plants. H.R. 2951 would have prohibited the operation of any nuclear power plant unless it had a government-certified radiological emergency response plan. Such plans would be have been required to provide reasonable assurance that public health and safety was not endangered by the operation of the facility.
