Press Release (Mar 12,2011)
Plant Status of Fukushima Daiichi Nuclear Power Station (as of 0AM March 12th )
All 6 units of Fukushima Daiichi Nuclear Power Station have been shut down.

Unit 1 (shut down due to earthquake)
- Reactor was shut down and nuclear steam is cooled by the isolation condenser.
- Currently, there is a possibility of a release of radioactive materials 
  due to decrease in reactor water level.  Therefore, the national government 
  has instructed evacuation for those local residents within 3km radius of 
  the periphery and indoor standby for those local residents between 3km and 
  10km radius of the periphery.

Unit 2 (shut down due to earthquake)
- Reactor was shut down and although nuclear steam had been cooled by the 
  Reactor Core Isolation Cooling system, the current operating status is 
  unclear.  However, reactor coolant level can be monitored by a temporary 
  power supply and the level is stable.
- Currently, there is a possibility of a release of radioactive materials 
  due to decrease in reactor water level.  Therefore, the national government 
  has instructed evacuation for those local residents within 3km radius of 
  the periphery and indoor standby for those local residents between 3km and 
  10km radius of the periphery.

Unit 3 (shut down due to earthquake)
- Reactor was shut down and is cooled by the Reactor Core Isolation Cooling 
  system.
- Currently, we do not believe there is any reactor coolant leakage inside 
  the reactor containment vessel.

Unit 4 (shut down due to earthquake)
- Reactor has been shut down and sufficient level of reactor coolant to 
  ensure safety is maintained.
- Currently, we do not believe there is any reactor coolant leakage inside 
  the reactor containment vessel.

Unit 5 (outage due to regular inspection)
- Reactor has been shut down and sufficient level of reactor coolant to 
  ensure safety is maintained.
- Currently, we do not believe there is any reactor coolant leakage inside 
  the reactor containment vessel.

Unit 6 (outage due to regular inspection)
- Reactor has been shut down and sufficient level of reactor coolant to 
  ensure safety is maintained.
- Currently, we do not believe there is any reactor coolant leakage inside 
  the reactor containment vessel.

We measured radioactive materials inside and outside of the periphery of 
the nuclear power station (outdoor area) by monitoring car and confirmed 
that there was no difference from ordinary level.

No radiation impact to the external environment has been confirmed.
We will continue to monitor in detail the possibility of radioactive material 
being discharged from exhaust stack or discharge canal.

Two subcontract workers were injured in the nuclear power station premise.  
One with a broken bone was transported to the hospital by an ambulance and 
the other by a company car.
Further, there are 2 TEPCO employees whose presence has not been confirmed.

We are presently checking on the site situation of each plant while keeping 
the situation of aftershock and Tsunami in mind.
