PISC-III - SECOND PROGRAMME ON STAINLESS STEEL SAMPLES, PARAMETRIC CAPABILITY AND RELIABILITY STUDIES
This report presents a programme for capability, parametric, and reliability studies of inspection personnel, equipment and procedures on wrought and cast stainless steel piping used in nuclear power plants. The report defines the specimen sets, test protocol and analysis methods to be used. The capability study is designed to identify procedures and have the potential to detect and size defects and to discriminate between flawed and unflawed material. The reliability study is meant to present a test that will measure in-service inspection performance (detection and false call capability) under realistic in-field conditions on realistic cracks. Two welded assembly sets (one for wrought or wrought plus cast, and one for cast stainless steel) are to be employed in the reliability study. Both the welded assemblies and test protocol are organized to simulate in-field conditions as closely as possible. The statistics and analysis methods used to quantify inspection performance are selected to be as comparable to PISC-II methods as possible. However, the methods used in PISC-II will be extended to allow false call effects to be evaluated. The parametric studies are organized to complement the capability and reliability studies by evaluating the effect of important material and defect variables. These studies will be performed under laboratory conditions with little or no replication performed by actual inspection teams.
