Déclenchement d’une alarme signalant une de fuite de sodium sur le surgénérateur de Monju sans qu’il y ait eu réellement de fuite. La cause de cette alarme apparemment intempestive est recherchée. Le réacteur est arrêté depuis le 20 septembre 2010 suite à la chute du barillet de chargement de combustible dans le réacteur...

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. (Jul. 31, 2012)
