Aging-seismic correlation study on Class 1E equipment. Final report. Revision

Creators

Description

This paper presents a new method of analysis for evaluating the effect of aging in electrical equipment on the seismic capacity. The method is based on the probability of mechanical failure of weak link materials which may be subjected to a load during an earthquake. It is shown that aging-seismic correlation is related to: number of age-degradable weak link components, rate of degradation in weak link components, the seismic stresses on the components and component material failure. Before conducting the Probabilistic Failure Analysis, preliminary screening for equipment with potential aging-seismic correlation is performed
