摘要：

A procedure has been developed for estimation of the failure probability of weld joints in nuclear piping susceptible to intergranular stress corrosion cracking. The procedure aims at a robust and rapid estimate of the failure probability for a specific weld with known stress state. Random properties of the crack initiation rate, the initial crack length, the in-service inspection efficiency, and the leak rate, are taken into account. A computer realization of the procedure has been developed for user-friendly applications by design engineers. Some examples are considered to investigate the sensitivity of the failure probability to different input quantities. (C) 1998 Elsevier Science Limited. All rights reserved.
