Status report : PISC III : Action 4 on austenitic steel testing
Capability and reliability studies of NDT procedures for the inspection of wrought and cast stainless steel piping used in nuclear power plants are presented. The capability study established procedures to discriminate between flawed and unflawed material. The reliability study was undertaken to quantify in-service inspection performance under realistic field conditions. Furthermore, parametric studies were performed to complement the capability and reliability studies by evaluating the effect of important material and flaw variables. The specimens used in these studies were cast-to-cast, cast-to-wrought, and wrought-to-wrought pipework welds. The evaluation methods used to quantify the inspection performance were selected to be as comparable as possible to the PISC II methods. The matrix of samples has also been designed to allow the implementation of specific statistical analysis procedures, for example ROC (Relative Operative Characteristics) analysis, for the evaluation of results.
