Kyushu Electric Power Co. stopped generating electricity at the Genkai nuclear power plant in Saga Prefecture on Saturday after a steam leak was detected in a reactor the previous day. The utility said that no radiation leaked and that it will inspect the reactor, which resumed operation just a week ago. According to Kyushu Electric, at around 7 p.m. Friday staff discovered steam leaking from the pipe of a device used to remove oxygen and other dissolved gases from feedwater used in steam generators. Reactor 3 resumed operation on March 23 after being offline for over seven years amid concerns about how to evacuate residents near the plant in a serious accident. It resumed power generation two days later.
