NDT as a tool, for Post-Irradiation Examination

摘要

Non-destructive testing scored important successes in nuclear field. All NDT techniques available nowadays provide comprehensible indications on the behaviour of the track. This paper reviews the NDT techniques used in the post-irradiated examination of fuel element taken from Es-salam nuclear reactor. Indeed, the fuel element emits alpha, beta and gamma rays, that why, measurement are done in hot laboratory in order to guarantee safe conditions for users. The first approach is to explore the influence of a wide range of variables on the fuel element during irradiation. The currently methods used, are visual inspection, dimensional measurement, eddy current testing, x radiography and gamma scanning. With these methods, it is possible to obtain large amounts of quantitative and qualitative information about the fuel element behaviour during irradiation.
