CURRENT PROBLEMS OF PROBABILISTIC SAFETY ANALYSIS OF FACILITIES USING ATOMIC ENERGY

摘要

A broader approach to probabilistic safety analysis of objects using atomic energy is examined. The goal of previous as well as current investigations is to show that the probability of serious accidents at a facility does not exceed prescribed values. In the approach proposed in the present article, the results of probabilistic analysis in the form of probabilities of accidents and expected consequences are tied to the magnitude of the harm done to the public and the environment under the condition that the owner of the object provides compensation for the harm done. Taking this factor into account, various forms of expenditures for guaranteeing the safety of a facility are analyzed and an algorithm for optimizing the total expenditure is given. The roles of the insurance system and the compensation process are examined. The conditions for optimal reduction of decommissioned objects using atomic energy into a safe state are investigated.
