Evaluation of the inspection results of the PISC III safe-end assembly no. 20 : Safe-ends nos. 21 and 22
The objectives of PISC II and PISC III exercise were to identify effective inspection techniques and procedures, and to inform codes and standards bodies of the results obtained for safe-end assemblies. This report covers the results obtained on the evaluation of assembly no. 20. This is a BWR shell with two set-in nozzles and safe-ends. Evaluation of the results indicates that assembly no. 20 was difficult to inspect. Procedures characterised by automatic scanning seem to be more effective for rejectable flaws than the group of procedures based on manual scanning. The evaluation of individual techniques shows that some could lead to high detection but none of them would produce, when used alone, the performance of the whole procedure.
