On November 1, 2005, Central Research Institute of Electric Power Industry (CRIEPI) established PD Center to contribute for the safety of nuclear power plant by tak ing a key role in the Japanese Performance Demonstration system. At the end of March 2006, Japanese Performance Demonstration (JPD) for flaw depth sizing of austen itic stainless steel pipes started. As of beginning of June 2006, 6 JPD examinations had been done for 18 candidates and 9 personnel had successfully cleared the ac ceptance criteria...

Report on Performance Demonstration for depth sizing of austenitic stainless steel pipes

The PD Center at the Central Research Institute of Electric Power Industry (CRIEPI) commenced Performance Demonstra tion examinations for flaw depth sizing of austenitic stainless steel pipes in March 2006. As of April, 2008, 18 ex amination courses have been completed and 22 out of 36 candidates passed the examination. Many candidates failed th e PD examination due to a failure to distinguish between crack tip echo and echo from weld to base-metal interface....

Report on Performance Demonstration for depth sizing of SCC flow in austenitic stainless steel pipes

The Japanese PD qualification examination for SCC through wall depth sizing started in March, 2006, and was operated by PD Center of Central Research Institute of Electric Power Industry (CRIEPI). As of March 31, 2009, 23 examination courses have finished and 27 out of 38 candidates passed the examination. The total number of test including retest was 63. Increase in the examination pass rate of retest personnel indicates improvements in the depth sizing technique through PD qualification examination...

Evaluation of SCC Depth Sizing Candidate and Performance

In our country's ISI, the ultrasonic examination has been stored remarkable success in detection of the SCC in a stainless steel piping weld. This result owes to the training in an inspection company and experienced personnel. However, considering latest reduction of an examination opportunity of SCC in an operating plant by the implementation of measures and the change of personnel's generation, it is required to rebuild the ability training system of examination personnel. This paper reviews the qu...

Validation of ultrasonic testing (UT) for detecting stress corrosion cracks (SCCs) in the Pressurizer's dissimilar metal weld of nuclear power plant, PWR, was carried out. Appropriate UT methods using probes consist of separate transmit and receive piezo-electric elements with longitudinal wave can detect both axial and circumferential SCCs ranged from 12% to 23% thickness of weld. ...
