Development of Evacuation Time Estimate Studies for Nuclear Power Plants

摘要

This update to NUREG/CR4831, State of the Art in Evacuation Time Estimate Studies for Nuclear Power Plants, integrates new technologies in traffic management, computer modeling, and communication systems to identify additional tools useful in the development of new, or updates to existing, Evacuation Time Estimates (ETEs). As advancements in technologies that support evacuations and evacuation planning continue, these new technologies should be considered. The Criteria for Preparation and Evaluation of Radiological Emergency Response Plans and Preparedness in Support of Nuclear Power Plants, NUREG-0654/FEMA-REP-1, Rev. 1, provided the initial guidance on development of ETEs. NUREG/CR-4831 provides guidance on the relevant information, assumptions, and methods to be used in performing Evacuation Time Estimate (ETE) studies. The purpose of the ETE is to provide a tool for preplanning as well as protective action decision making. The ETE identifies potential challenges to efficient evacuation, such as traffic constraint, allowing mitigative measures to be preplanned. The value of the ETE is in the methodology required to perform the analysis rather than in the calculated ETE times (NRC, 1980a. Supplement 2).
