Analysis of the failure probability of pipelines and equipment with service life extension of nuclear power plants

A method is proposed for calculating the failure probability of pipelines and equipment that takes account of experience in operating the structures in different regimes and aging. The random quantities used in the method are parameters characterizing the applied loads and defects as well as the str...

Zusammenfassung:A method is proposed for calculating the failure probability of pipelines and equipment that takes account of experience in operating the structures in different regimes and aging. The random quantities used in the method are parameters characterizing the applied loads and defects as well as the strength, mechanical, and thermophysical properties of metal. An example of a calculation of the failure probability for a RBMK emergency recirculation pipeline of emergency feed pumps with service life extension is presented.
