Effectiveness and reliability of inservice inspection: a Round Robin test
An ongoing program, under the sponsorship of the US Nuclear Regulatory Commission (NRC), is directed toward measuring the effectiveness and reliability of inservice inspection (ISI) of Light Water Reactor systems. As a part of this program, a Round Robin is being conducted on the reliability of primary piping system ISI. The Round Robin involves six inspection teams, approximately 1500 test sample measurements, and 3240 inspection manhours over a period of seven months. The test materials include 254 mm (10 in.) Schedule 80 stainless pipe, with intergranular stress corrosion (IGSCC) and fatigue cracks, as well as 844.6 mm (33-1/4 in.) diameter centrifugally cast stainless steel and clad ferritic PWR main coolant pipes with fatigue cracks. Principle results of the Round Robin to be reported include: probability of detection and recording probability as a function of material, crack type, size and location (near or far side of the weld); the effectiveness of Code required sensitivity, field procedures, and an improved procedure; and the influence of access conditions (laboratory and field conditions).
