The Japan Times reported today:
Kyushu Electric Power Co. said Saturday that 1.8 tons of radioactive water leaked in the purification system of an idled reactor at the Genkai power plant in Saga Prefecture, and drew flak for failing to promptly disclose the incident to local authorities.
The water leaked from a joined area involving the pumps but did not result in radioactive material exiting the reactor building, the utility said.
Kyushu Electric did not promptly report the problem with the reactor:
The utility detected the leak Friday morning but only told local governments it was having pump troubles with its No. 3 reactor, which is undergoing a regular check.
The lack of disclosure upset Genkai Mayor Hideo Kishimoto.
“It should have been reported properly (to the town of Genkai and Saga Prefecture). I have been repeatedly telling Kyushu Electric to change its corporate culture,” he said.
