TSURUGA, Japan (Kyodo) -- Part of the Monju prototype fast-breeder reactor halted last weekend due to human error, the Japan Atomic Energy Agency said late Friday on the heels of an effective ban on restarting the reactor due to the operator's deteriorating safety culture.
A heater that keeps sodium molten as a secondary coolant for the reactor in Tsuruga, Fukui Prefecture, in western Japan, halted for some 30 minutes from about 4:30 p.m. Sunday during a checkup of a power supply system, causing the sodium temperature to fall about 40 C from 200 C, while its melting point is around 98 C, it said.
The JAEA attributed the error to insufficient information in its service manual, and said it reported the event Monday to the Nuclear Regulation Authority and the local governments, but lagged in making it known to the public as it was too minor an incident to compel it to report to authorities under internal rules.
The agency's failure to properly inspect Monju prompted the nuclear authority to issue an order May 30 that effectively prohibits the reactor from restarting until the state-run operator improves its safety management system.
