Emergency Preparedness: NRC Needs to Better Understand Likely Public Response to Radiological Incidents at Nuclear Power Plants

A letter report issued by the Government Accountability Office with an abstract that begins "The U.S. Nuclear Regulatory Commission (NRC) and the Federal Emergency Management Agency (FEMA) are collectively responsible for providing radiological emergency preparedness oversight and guidance to commercial nuclear power plant licensees and local and state authorities around the plants. In general, NRC is responsible for overseeing licensees' emergency preparedness at the plant (on-site), and FEMA is responsible for overseeing preparedness by local and state authorities around the plant (off-site). NRC and FEMA have also established a 10-mile emergency planning zone around nuclear power plants. Licensees are responsible for managing on-site radiological emergency preparedness and developing and maintaining plans that define activities that the nuclear power plant must take to prepare for and respond to a potential incident at the plant. Participating local and state authorities within the 10-mile zone must develop protective actions for responding to a radiological incident, including plans for evacuations and sheltering in place. A recent NRC task force considered the adequacy of the zone size and concluded that no change was currently needed but will be re-evaluated as part of its lessons learned efforts for the Fukushima incident.
