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...

For the commercialization of fast breeder reactors (FBR), it is essential to enhance the economic competitiveness by reduction of total cost by elongation of plant service period. In this point of view, it is important to establish the assessment method of integrity of aged weld joint and repair welding for the components of future long life FBR. In the present study, evolution of microstructure is evaluated for the 304SS-304SS weld joint which was used for 88,000h at 526-545°C in the French proto-typ...

The purpose of this study is to develop a hybrid sensor to be able to measure two or more physical values (the pipe surface temperature, the pipe wall thinning and the temperature of an internal fluid) with one sensor with an electromagnetic acoustic transducer. Each result of a measurement can improve the measurement precision by doing working that calibrate each other. The piping surface temperature was measured by converting the direct current resistance at the temperature by using the EMAT coil. A...

Residual stress improvement technologies have been developed and applied to Boiling Water Reactor (BWR) plant components in order to prevent from stress corrosion cracking (SCC) of stainless steel and Ni-based alloy materials. Water Jet Peening (WJP) is one of the effective procedures for residual stress improvement, and has the various advantages for the application to the reactor internal components of the operating nuclear power plants because WJP uses only water for residual stress improvement. As...

The remote operated vibrating sample magnetometer (VSM) for neutron irradiated samples has been developed. The maximum range of applied magnetic field is more than ±0.5/?0 A/m, and the resolution of magnetic moment is higher than 5 ×10-8 A?m2. The hysteresis loops of neutron irradiated samples were measured by this VSM, and the relationships between dose, which is one of epresentative irradiation parameter, and magnetic properties such as magnetic coercive force were examined. As result, it was revealed tha...
