Mainichi Shimbun – Radioactive water leaks at Kyushu Electric’s Genkai reactor
SAGA (Kyodo) — Kyushu Electric Power Co. said Saturday that 1.8 tons of coolant water containing radioactive materials had leaked within a purification system at an idled reactor at its Genkai nuclear power plant in Saga Prefecture.
But the utility failed to report the leak to the local governments when it detected it Friday morning, only notifying them of trouble with pumps in the system for the No. 3 reactor, which has been suspended for regular checkups, prompting the Genkai mayor to complain.
The water leaked from a joining area of the pumps, with no radioactive materials leaking outside the reactor building, and has been completely recovered, the utility said, adding that the intensity of radioactive matter contained is unknown.
On Friday, the company serving the Kyushu region in southwestern Japan said a rise in temperature over 80C at the base of one of the pumps triggered an alarm, but didn’t reveal the water leak on the grounds that it did not go outside the purification system.
The government’s Nuclear and Industrial Safety Agency said the leak within the purification system posed no immediate safety threat and urged the firm to investigate the cause.
But Genkai Mayor Hideo Kishimoto said, “It should have reported properly (to the Genkai town and Saga prefectural governments).I have been repeatedly telling it to change its corporate culture.”
