On August 9th 2004, the secondary piping rupture accident at Mihama Unit 3 took 5 innocent lives away and injured 6 others. We would like to express our full condolences on the victim of the accident and their families. We would also like to express our full apology regarding the accident. In this paper, since th e accident was severe enough to reconsider our maintenance duty, consideration from the perspective of the “Maintenology“ were discussed to expand the lesson s learnt from the accident to the overall nuclear power plant maintenance duty and how the maintenance duty should be done in the future were also discussed.
