The PISC parametric study on the effect of cast austenitic steel macrostructure on the capability of ultrasonic examination
- AIB-Vincotte, Brussels (Belgium)
Within the framework of Action 4 (Austenitic Steel Testing) of PISC 3, a parametric study was carried out on a set of centrifugically cast stainless steel samples, representative of the main coolant piping of pressurized water nuclear reactors. The samples are obtained from different manufacturers, and feature various grain structures and dimensions. Artificial and realistic flaws were used to assess the detection and sizing capability of ultrasonic examination techniques. The paper analyzes the data as a function of the metal structure and of the main parameters of the testing techniques, which include TRL contact probes and immersion focusing transducers. Guidelines are deduced as to the selection of inspection techniques, in relation with the metallurgical structure of each specimen. In addition, the influence of the presence of a weld across the wavepath is evaluated, as well as the similarity, between the responses obtained from crack-like machined reflectors and mechanical fatigue cracks.
