The five post-irradiation examination facilities in the Oarai Research and Development Institute of the Japan Atomic Energy Agency have been operated for over 40 years in order to investigate the irradiation performance and physicochemical characteristics of nuclear fuels and materials for fast reactors. The equipments associated with these facilities have been managed to maintain secure from the problems that occurred in the process of aging. Therefore, we established a safety assessment method for aging f...

The technique of obtaining shape of inclined defect at heat affected zon e for welded specimen of high chromium steel was proposed. In this techn ique, magnetic flux leakage measurement and the inverse analysis using s ingular value decomposition were used. Suitable defect shape was obtained from the magnetic flux density distribution under the high magnetic fiel d without being subject to the influence of a welding part. Under the lo w magnetic field, suitable defect shape was obtained by subtracting the ...
