Alarm rings at Monju N-reactor; no leak(Yomiuri)

FUKUI (Jiji Press)–The Japan Atomic Energy Agency said Monday that a sodium leak alarm went off in an auxiliary building at its Monju fast-breeder nuclear reactor at about 3:40 a.m., but later confirmed no leak had occurred.

When working correctly, the alarm rings when sodium, which is used as a coolant, is detected in the atmosphere around the pipes of a temporary storage and cooling facility for spent nuclear fuel.

The Monju reactor in Tsuruga, Fukui Prefecture, has been suspended since September 2010, when a fuel exchange device fell into the reactor.

The agency is investigating why the alarm sounded. The incident will be reported to the Nuclear and Industrial Safety Agency and the Fukui prefectural government.
