概要
Additional RPV surveillance tests are required to extend the operation license of nuclear power plants under the new regulation. Since the number of surveillance test specimens is limited, it is important to establish a reconstitution technique of the surveillance test specimen using the remaining undeformed part of the tested specimen. To evaluate the applicability of electron beam welding, the confirmatory tests such as Charpy impact tests were conducted using unirradiated test specimens reconstituted by the electron beam welding.
