2001 replacement plan of main component for Genkai nuclear power plant unit 1 and 2

The commercial operation of Genkai unit 1 started in October 1975 and Genkai unit 2 in March 1981. Each of them is a two-loop type PWR plant whose output is 559 MW. Until now Genkai unit 1 and 2 have been operating satisfactorily with good operating performance since their commercial operation started. Meantime we have made efforts to improve the reliability of facilities and their functions by systematically performing improvement and repair work reflecting the lessons learned from operation experience of nuclear power plants at home and abroad and the result of technical development. We have decided to replace main component during the 20. outage of Genkai unit 1 and the 16. outage of Genkai unit 2 which are scheduled in March 2001, in order to reduce future radiation exposure and to improve the reliability.
