Press Release (Mar 12,2011)
Plant Status of Fukushima Daiichi Nuclear Power Station (as of 8PM March 12th )
All 6 units of Fukushima Daiichi Nuclear Power Station have been shut down.

Unit 1(Shut down)
- Reactor has been shut down. However, the unit is under inspection due
  to the explosive sound and white smoke that was confirmed after the big
  quake occurred at 3:36PM. 4 workers were injured due to this incident
  and they were transported to the hospital. 

Unit 2(Shut down)
- Reactor and Reactor Core Isolation Cooling System have been shut down.
  Current reactor water level is lower than normal level, but the water
  level is steady. After fully securing safety, we are preparing to
  implement a measure to reduce the pressure of the reactor containment
  vessels under the instruction of the national government.

Unit 3(Shut down)
- Reactor has been shut down and we continue injecting water by High
  Pressure Core Injection System. After fully securing safety, we are
  preparing to implement a measure to reduce the pressure of the reactor
  containment vessels under the instruction of the national government.
- Currently, we do not believe there is any reactor coolant leakage 
  inside the reactor containment vessel.

Unit 4 (shut down 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 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.

Currently, we are implementing a measure to reduce the pressure of
the reactor containment vessels of Unit 1. We have confirmed that
the radiation exposure of 1 TEPCO employee, who was working inside
the reactor building, exceeded 100mSv (106.3mSv). Because of the absence
of industrial physician, we were scheduling diagnosis later. However, 
we have transported him to the hospital because of the deconditioning. 

We measured radioactive materials inside of the nuclear power station 
area (outdoor) by monitoring car and confirmed that radioactive materials
level is higher than ordinary level. Also, the level at monitoring post
is higher than ordinary level.

We will continue to monitor in detail the possibility of radioactive 
material being discharged from exhaust stack or discharge canal.

The national government has instructed evacuation for those local
residents within 20km radius of the periphery because it's possible that
radioactive materials are discharged.

Two workers of a cooperative firm 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.
In addition, one subcontract worker standing near important earth 
quake-proof buidling was unconscious and transported to the hospital by 
an ambulance. 

We will continue to take all measures to restore the security of the site
and to monitor the environment of the site periphery.
