Monju fast breeder reactor's sodium detector hits trouble

TOKYO (Kyodo) -- A sodium detector at Japan's prototype fast-breeder reactor Monju went out of order, the government's Nuclear and Industrial Safety Agency said Thursday.

But neither sodium leakage nor damage to the environment has been reported, said the agency under the Ministry of Economy, Trade and Industry.

The state-run Japan Atomic Energy Agency, the operator of the Monju reactor in Tsuruga, Fukui Prefecture, is currently working to repair the detector, it said.

An alarm sounded at the central control room shortly after 3 p.m. Thursday notifying of trouble at the detector. A fan that sends air around the sodium coolant piping to the detector apparently came to a halt, it said. Source
