As of the beginning of 1995, forty-eight (48) light water reactors (LWRS) are operating in Japan, twenty-six (26) of which are boiling water reactors and twenty-two (22) pressurized water reactors, and more are under planning or construction phase. These LWRs constitute the main body of nuclear power generation units in Japan, although there are three other power reactors of different kinds; a gas-cooled reactor, an advanced thermal reactor and a fast breeder reactor. The oldest ones among the LWRs were commissioned in 1970, experiencing more than twenty years of operation. Consideration for the increasing aged plants brings up an important technological task to maintain and improve the reliability of operating nuclear plants, which would be essential, technically and socially, for nuclear power generation in Japan to keep growing. With these backgrounds, the Japan Power Engineering and Inspection Corporation (JAPEIC), under entrustment from the Ministry of International Trade and Industry (MITI), constituted a technical committee, named the Committee on Nuclear Plant Operation and Maintenance Standards (POMS Committee) in the fall of 1993, to develop a maintenance code for operating nuclear power plants. This paper presents the summary on the Committee and its activities.
