In 1986 the Committee for the Safety of Nuclear Installations (CSNI) discussed the list of actions of the third phase of the Programme for the Inspection of Steel Components (PISC III) and proposed Action 4 on austenitic steel testing. Within the framework of Action 4 of the PISC III three capability studies on stainless steel welds have been conducted. One of these capability studies made use of six wrought-to-wrought stainless steel assemblies that contained intergranular stress corrosion cracks (IGSCC), thermal and mechanical fatigue cracks and PISC type A flaws. In this paper the simulation of an ASME type performance demonstration test using the PISC III results of the wrought-to-wrought capability study will be discussed. First a verification will be done of the extent that the PISC specimen set meets the ASME specimen requirements. These relate to the specimens, the number of cracks, crack types and crack sizes. The results of the simulation of the performance demonstration test will be presented for detection, false calls, depth and length sizing. The conclusions that one can draw from this simulation will be compared with those obtained from the PISC evaluation.
