Research on Nuclear Safety Events Classing Method of Minitype PWR

Abstract

Classification of nuclear safety events is the important evidence and basis for determining the emergency disposal and response level as soon as the PWR accidents. Taking the minitype PWR as the research object, basing on the available NPP accidents classing method, determine the nuclear safety accidents grading index and calculate the index weighting factor by using the analytic hierarchy process (AHP) so as to determine the accidents level.
