The Nuclear and Industrial Safety Agency and Kansai Electric Power Company have apologized for delaying disclosure of the news that an automatic warning occurred at the No. 3 reactor at the Oi nuclear power plant in Fukui Prefecture on Tuesday night.
An alarm bell activated at around 9:50 p.m. Tuesday, reporting that the water level in the reactor 3 cooling tank had fallen at least 5-10 centimeters, officials said. KEPCO said that more water has been put into the tank as a precautionary measure.
The alarm was the first sign of trouble since the government decided to restart the units 3 and 4 Saturday. Disclosure of Tuesday’s incident came at a news conference at 11 a.m. Wednesday -- about 13 hours after the warning occurred, Fuji TV reported.
Nuclear and Industrial Safety Agency director Yasushi Morishita apologized at the news conference, saying his lapse in judgment caused the delay. He was quoted as saying that officials didn't think the alarm merited a news conference, Fuji reported.
The agency held a second news conference later Wednesday, at about 4 p.m., and offered its assurances that future disclosures would be made in a more timely manner, Fuji reported.© Japan Today
