Suppressing the stress corrosion cracking by reducing carbon contents in austenitic stainless steels seems to be not effective on core shrouds used in boiling water reactor in Japan. Trans-granul ar cracking was found out in the shrouds. To clarify a mechanism of the cracking, stress measurement on specimens under stretched condition in hot water has been attempted in the present study. A n in-situ device for diffraction measurements in synchrotron radiation facility has been developed by the present autho...

It is necessary to confirm whether the feed water nozzle inside corner has crack by eddy current testing, to enable long-term operation of a plant. Therefore, we performed eddy current testing using various types of specimen to collect basic data (probability and length measurement accuracy) of the eddy current testing methods, complying with JEAG4217. As a result, eddy current testing was effective for the inspection of feed water nozzle inside corner. ...
