DEVELOPMENT OF MODELS FOR RESIDUAL LIFE PREDICTION OF NUCLEAR POWER PLANT EQUIPMENT

摘要

Determination of a residual life of the nuclear power plants (NPP) equipment and its individual prediction is an extremely urgent task. Solving the given problem will allow to ensure a high level of reliability, safety and economic efficiency of operating nuclear power plants. The problem of calculating a residual life prediction for NPP equipment is emphasized in most part of the developed countries of the world. Also a special attention is paid to the given problem in Russia too. The classical approach of an estimation and prediction of a residual life is the deterministic approach. At present the method is progressing based on the parameters failures model. In present-day the description of degradation processes using random processes is considered to be the most promissing direction in theory of probability.
