Press Release (Mar 13,2011)
Plant Status of Fukushima Daiichi Nuclear Power Station (as of 0pm March 13th)

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. 
- We have been injecting sea water and boric acid which absorbs neutron 
  into the reactor pressure vessel.
Unit 2 (Shut down) 
- Reactor has been shut down and Reactor Core Isolation Cooling System has 
  been injecting water to the reactor. Current reactor water level is lower 
  than normal level, but the water level is steady. After fully securing 
  safety, measures to lowering the pressure of reactor containment vessel 
  has been taken, under the instruction of the national government.
Unit 3 (Shut down) 
- Reactor has been shut down. However, as High Pressure Core Injection 
  System has been automatically shut down and water injection to the 
  reactor was interrupted, following the instruction by the government and 
  with fully securing safety, steps to lowering the pressure of reactor 
  containment vessel has been taken. Spraying in order to lower pressure 
  level within the reactor containment vessel has been cancelled.
- After that, safety relief valve has been opened manually, lowering the 
  pressure level of the reactor, which was immediately followed by 
  injection of sea water and boric acid which absorbs neutron, into the 
  reactor pressure vessel. 
- 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.
Casualty 
- 2 workers of cooperative firm were injured at the occurrence of the 
  earthquake, and were transported to the hospital.
- 1 TEPCO employee who was not able to stand by his own with his hand 
  holding left chest was transported to the hospital by an ambulance.
- 1 subcontract worker at important earthquake-proof building was 
  unconscious and transported to the hospital by an ambulance.
- The radiation exposure of 1 TEPCO employee, who was working inside the 
  reactor building, exceeded 100mSv and was transported to the hospital.
- 4 workers were injured and transported to the hospital after explosive 
  sound and white smoke were confirmed around the Unit 1.
- Presence of 2 TEPCO employees at the site are not confirmed
Others 
- 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.
 
- We will continue to take all measures to restore the security of the site 
  and to monitor the environment of the site periphery.
