東京電力によると、８日午後、福島第１原発１、２号機で停電が発生、中央制御室の照明が消えた。ほかにも、１号機への窒素供給装置やモニタリングポストの一部が止まるなどの影響が出ており、同社が原因を調査している。
According to TEPCO, power went out in the afternoon on June 8 in the Reactors 1 and 2 at Fukushima I Nuclear Power Plant. The lights are out in the central control rooms. The nitrogen injection system in the Reactor 1 and some of the monitoring posts have stopped. TEPCO is investigating the cause.
A tweet from NHK's Science and Culture division says this about the nitrogen injection system:
停止というより、圧力が上昇したため窒素供給を待機中です
Rather, they halted the nitrogen injection because the pressure [inside the Containment Vessel] went up.
Minor electrical problem, I'm sure. Nothing to worry about. Besides, the Reactor 1's Containment Vessel has been breached. How could the pressure go up?
