Abstract This paper summarizes the maintenance activities and Plant Life Management (ageing management review) in Japanese nuclear power plants. The electric ut ilities evaluate the measures against ageing phenomena which will be taken at each plant by the time the plant has reached its 30th year of operation. The measur es utilities against ageing phenomena are to be carefully taken into the maintenance program based on these evaluation results. At the same time, these measures will be re-evaluated during...

Maintenance Activities and Plant Life Management of Nuclear Power Plants

After the Fukushima-daiichi accident, the KANSI Electric Power has implemented various safety measures against severe accident for nuclear power plants. In this paper, we will explain about overview of measures and internal flooding caused by the high energy line break. The high energy line break may cause common mode failure which damages the multiplexed and diversified protection system at the same time by a single piping break. Therefore we have to take all possible measures for the prevention from int...

Safety measures for severe accident on the KANSAI nuclear power plants

A special committee for the “Development of Research & Development Roadmap regarding Power Reactor Safety” was formed in the Atomic Energy Society of Japan (AESJ) in 2004 und er a contract with the Japan Nuclear Energy Safety Organization to examine the “Aging and Plant Life Management Roadmap”. The examination by the special committee was conducte d based on a common understanding among the industrial, governmental and academic communities to figure out the future strategies for plant life management in o...
