Japanese code for ultrasonic testing in-service inspection, named JEAC 4207, allows inspection through weld metal, in case that some factors, such as weld crown or other structures, disturb scanning. The applicability of through weld metal inspection had been reported with BWR piping. This paper will be technical basis of applicability of through weld metal inspection for PWR piping, which is thicker and has factor hardens inspection. The data successfully shows the capability for detection and sizing...

A diffraction spot trace method (DSTM) was developed to measure internal stresses of materials with coarse grains. The DSTM was applied to light metals, such as aluminum alloy and magnesium alloy. In this study, validity of the DSTM was examined using high energy synchrotron X-rays of 70 keV. The specimen was a welded plate of austenitic stainless steel (SUS316L). The thickness of the specimen was 9 mm. The improved rotating slit-system was used, and PILATUS was used as an area detector. It was diffi...
