Résumé

Abstract. This paper describes the cracking of stainless steel piping under Inter-granular Stress
Corrosion Cracking (IGSCC) conditions using probabilistic fracture mechanics that predict the
impact of in-service inspection (ISI) programs on the reliability of specific nuclear piping systems that have failed in service. The IGSCC is characterized by a single damage parameter, which
depends on residual stresses, environmental conditions, and the degree of sensitization. The
Probability of Detection (POD) curves and the benefits of in-service inspection in order to reduce
the probability of the leak for nuclear piping systems subjected to IGSCC were discussed. The
results show that an effective ISI requires a suitable combination of crack detection and inspection schedule. An augmented inspection schedule is recurred for piping with fast-growing crack to ensure that the inspection is done before the cracks reach critical sizes and that the use of a better inspection procedure can be more effective than a tenfold increase in the number of inspections of inferior quality.
