Subject: Fukushima Daini information
Today at 2:46PM, turbines and reactors of Tokyo Electric Power Company‘s Fukushima Daini Nuclear Power Station Units 1 to 4 (Boiling Water Reactor,
rated output 1,100 Megawatts) that had been operating at rated power automatically shutdown due to the Miyagiken-oki Earthquake.
Currently, reactor water level for Units 1 to 4 is maintained by injecting water into the reactors by the Reactor Core Isolation Cooling System.
The reactors are maintained at a subcritical condition.
For Unit 1, the emergency core cooling system automatically started up due to increase in the reactor containment pressure assumed to be caused by leakage of reactor coolant in the reactor containment.
Hence, at 5:35PM, it was decided that a specific incident stipulated in Article 10, Clause 1 of the Act on Special Measures Concerning Nuclear Emergency Preparedness *1 has occurred.
Indication of the monitoring posts installed in the periphery of the power station is no different from usual and thus no radiation impact to the
external environment is confirmed at this moment.
We will continue to monitor in detail the possibility of discharge of radioactive material from exhaust stacks and coolant water discharge canal.
