NEUTRON IRRADIATION OF MATERIALS AND ITS EFFECT ON STRUCTURAL INTEGRITY

摘要：

This paper describes the Neutron Radiation Damage issues that have an impact on structural integrity in current nuclear plant. Emphasis is given to two major problems of current importance: irradiation- assisted inter-granular cracking (IASCC) in austenitic steels; and ductile to brittle transition temperature shift (DBTT) in reactor pressure vessel steels. The approach used will be to survey modelling techniques that have been applied to the phenomena and to evaluate the best models to describe materials degradation in circumstances appropriate to IASCC and DBTT shift. The model predictions are compared with plant inservice observations. The result is a mechanistic interpretation of these two important structural integrity-related effects which can be used to help to design future plant with greater confidence.
