1 1 i Briefing Paper on Emergency Planning Zones For Commercial Nuclear Power Plants in the United States Based upon requirements of the Nuclear Regulatory Commission, commercial nuclear I power plants in the U.S. have two concentric emergency planning zones (EPZs). EPZs are defined as the areas for which planning is needed to assure that prompt and effective actions can be taken to protect the public in the event of an accident. The choice of the size of the Emergency Planning Zones represents a judgment on the extent of detailed planning which must be performed to assure an adequate response. In a particular emergency, protective actions might well be l restricted to a small part of the planning zones. On the other hand, for the worst possible accidents, protective actions might need to be taken outside the planning zones. The first zone, called the plume exposure pathway EPZ, is an area of about 10 miles in radius from the center of the plant. The major protective actions planned for this EPZ, evacuation and sheltering, would be employed to reduce fatalities and injuries from exposure to the radioactive plume from the most severe of the core-melt accidents and to limit unnecessary radiation exposures to the public from less severe accidents at nuclear power plant.c. l The second zone, called the ingestion pathway EPZ, is an area of about 50-miles in radius from the center of the plant. The major protective actions planned for this zone, putting livestock on stored feed and controlling food and water, would be employed to reduce exposure to the public from ingestion of contaminated food and water. The ingestion exposure pathway EPZ of 50 miles was selected because Federal protective action guidelines would generally not be exceeded beyond 50 miles for a wide spectrum of hypothetical accidents. FoiA-8I-M r M % \\? t-I t

+ m 2 The response measures established within the 10-mile and 50-mile EPZs can and j will be expanded if the conditions' of a particular accident warrant it. Also, although an EPZ is generally circular, the actual shape is based on local factors such as demography, topography, access routes and governmental jurisdictional { boundaries at a particular site. Smaller EPZs have been established for gas-ecoled power reactors and smaller water-cooled power reactors. The principal technical documents that describe the process of defining the size of the EPZs and the planning and protective measures to be taken within them are NUREG-0396, EPA 520/1-78-016, " Planning Basis for the Development of 9 State and Local Government Radiological Emergency Response Plans in Support of Light-Water Nuclear Power Plants," December 1978 and NUREG-0654/ FEMA-REP-1, Revision 1, " Criteria for Preparation and Evaluation of Radiological Emergency Response Plans and Preparedness in Support of Nuclear Power Plants," November 1980. The principal technical study upon which the sizes of the emergency planning zones were based is NUREG-75/014. " Reactor Safety Study: An Assessment of Accident Risks in U.S. Commercial Nuclear Power Plants," October 1975, WASH-1400. The Federal government will study the reactor accident in Russia along with other ongoing studies in the U.S. and abroad to determine if the size of the present emergency planning zones around U.S. commercial power plants needs to be reevaluated. 3vift-\\l
