Abstract

Abstract

Austenitic Stainless Steel Castings in LWR nuclear power plants are susceptible to thermal aging at operating temperature.This article describes the mechanism of thermal aging for CASS components.It gives a general procedure for thermal aging management in nuclear power plants（three steps: susceptibility screening,assessment of degree of material embrittlement and ISI programme renew） on the basis of the aging management practices.Then it gives some advices about thermal aging management of nuclear power plants in China.
