It is recognized that good preparedness in advance of an emergency can substantially improve the emergency response to a nuclear or radiological accident. This paper presents the methodology and results of the technical considerations for off-site emergency planning using a probabilistic accident consequence assessment model. Calculations of the off-site consequence have been made of postulated accidents with source terms derived from a generic level 2 PSA of the reference plant in Japan. The preliminary results provided the insights of technical guidance for the development of protective actions such as sheltering, evacuation, and administration of stable iodine.
