ANOTHER ACCIDENT AT JAPANESE NUCLEAR PLANT:
COOLANT LEAK AT HEAVY-WATER MODERATED REACTOR FUGEN;
17 HOURS DELAY IN NOTIFICATION OF THE EVENT,
ANOTHER VIOLATION OF SAFETY AGREEMENT

29 October 1999

A minor accident at Japan Nuclear Fuel Cycle Development Institute (JNC, former PNC)'s experimental nuclear reactor Fugen (165MW, ATR-HWR, heavy water moderated, light water cooled) occurred at around 22:38 (Japanese Standard Time; GMT+900) on 27 October.

Some 6 liters of radioactive coolant water leaked out of one of the 224 fuel tubes that constitute the reactor core. The upper seal of the tube was malfunctioning. The operators decided to shut down the reactor manually, which was completed early this morning (29 Oct).

JNC claims no radioactive release off site.

ATR Fugen is located in Tsuruga City, Fukui Prefecture, mid-west Japan on the coast of Japan Sea. It is not far from the FBR Monju site in the same city.

It was only 17 hours after the operators became aware of the leakage that the local government was notified of the accident. It is a clear violation of the safety agreement between JNF and the Fukui Prefecture. Naturally, the prefecture administration is very unhappy about it.

*news source: Mainichi Newspaper, 29 October 1999, based on the JNF press release of 28 October.

Tokai accident updates will follow soon.
