Modern tasks of probabilistic safety analysis for nuclear facilities

One dwells upon a more comprehensive approach to ensure the probabilistic safety analysis of the commercial nuclear power plants. The efforts undertaken earlier and under way now aim to demonstrate that the probability of severe accidents at a commercial facility is within the prescribed values. The described approach envisages coordination of the probabilistic analysis results in the form of the probabilities of accidents and the anticipated effects with the scale of the public and the environmental damage provided that the mentioned damage should be compensated by the facility owner. On the basis of the mentioned factor one analyzes various costs to ensure safety of a facility and presents the algorithm to investigate ways to optimize the total costs. One considers the insurance system role in the damage compensation procedure. One studies the optimal procedure conditions to ensure the safety of the decommissioned commercial nuclear power plants
