Abstract
In Japan, the Ministry of International Trade and Industry (MITI) is responsible for the safety and reliability of nuclear power plants. MITI formed a committee to develop a policy and action plan to develop advanced or new technology for aging nuclear power plants. MITI assigned the Japan Power Engineering and Inspection Corporation (JAPEIC) to manage the project on Plant Life Management Technology (PLIM), in accordance with the committee's report. The PLIM Project includes addressing the issue of irradiation embrittlement of reactor pressure vessel (RPV) steels, the issue of thermal aging of main coolant piping, and technology for the reconstitution of tested surveillance capsule specimens. This paper presents the planning and status of two of the ongoing projects, namely irradiation embrittlement of RPV steels and the development of technology for reconstitution of surveillance capsule specimens.
