All 6 units of Fukushima Daiichi Nuclear Power Station have been shut down.

Unit 1(Shut down) 
- Reactor has been shut down. However, the explosive sound and white smoke
  were confirmed after the big quake occurred at 3:36PM Mar 12th. It was 
  assumed to be hydrogen explosion.
- We have been injecting sea water 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. However, the level of reactor
  coolant had dropped and the reactor pressure had increased because
  the system stopped. The national government instructed that measures are
  taken to lower the pressure within the Reactor Containment Vessel and
  to inject sea water into the Reactor while carefully confirming safety.
  The level of reactor coolant and the pressure of the Reactor had resumed. 
- At approximately 6:00AM on March 15, 2011, an abnormal noise began 
  emanating from nearby Pressure Suppression Chamber and the pressure
  within this chamber decreased. 
- While we continue sea water injection operations, we temporarily moved
  TEPCO employees and workers from other companies not directly involved
  in this work to safe places.

Unit 3(Shut down) 
- Reactor has been shut down. However, the explosive sound and white smoke
  were confirmed at 11:01AM Mar 14th. It was assumed to be hydrogen explosion.
- Fog like steam was confirmed from the reactor building at 8:30AM on
  March 16th, 
- We continue monitoring as it was reported that the pressure of
  the Suppression Chamber has been temporarily increasing since 
  approximately 6:15AM on March 17th.
- We have been injecting sea water into the reactor pressure vessel.

Unit 4 (outage due to regular inspection) 
- Reactor has been shut down. However, at approximately 6AM on March 15th.
  we have confirmed the explosive sound and the sustained damage around 
  the 5th floor rooftop area of the Nuclear Reactor Building.
- On March 15th and 16th, we respectively confirmed the outbreak of fire 
  at the 4th floor of the northwestern part of the Nuclear Reactor 
  Building. We immediately reported this matter to the fire department and
  the related authorities. TEPCO employees confirmed that each fire had 
  already died down by itself. We will continue to carefully monitor 
  situations.
- Currently, we do not consider any reactor coolant leakage inside 
  the reactor containment vessel.

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

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

Cooling spent fuel pools 
•On Unit 3, water discharge by Self-Defense Force's helicopters had been
  conducted since 9:48 AM in the morning on March 17th.
•On Unit 3, water discharge by the riot police's high-pressure water 
  cannon trucks and Self-Defense Force's fire engines had been conducted 
  since approximately past 7PM on March 17th and they had finished water 
  discharge at 8:09PM. 
•We are considering further water discharge at Unit 3 and others subject 
  to the conditions of spent fuel pools when we get ready.

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 holding left chest
  with his hand, was transported to the hospital by an ambulance.
- 1 subcontract worker at the key 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 he was transported to 
  the hospital.
- 2 TEPCO employees felt bad during their operation in the central control
  rooms of Unit 1 and 2 while wearing full masks, and were transferred 
  to Fukushima Daini Power Station for consultation with a medical advisor.
- 4 workers were injured and transported to the hospital after explosive
  sound and white smoke were confirmed around the Unit 1.
- 11 workers were injured and transported to Fukushima Daini Nuclear Power
  Station etc. after explosive sound and white smoke were confirmed around
  the Unit 3.One of the workers was transported to the FUKUSHIMA Medical
  University Hospital at 10:56AM 
- Presence of 2 TEPCO employees at the site is not confirmed. 

Others 
- We measured radioactive materials (iodine etc.) inside of the nuclear
  power station area (outdoor) by monitoring car and confirmed that 
  radioactive materials level is getting higher than ordinary level. 
  As listed below, we have determined that specific incidents stipulated
  in article 15, clause 1 of Act on Special Measures Concerning Nuclear
  Emergency Preparedness (Abnormal increase in radiation dose measured
  at site boundary) have occurred.

- The national government has instructed evacuation for those local
  residents within 20km radius of the periphery and evacuation to inside
  for those residents from 20km to 30km radius of the periphery, because
  it's possible that radioactive materials are discharged.
- At approximately 10AM on March 15, we observed 400mSv/h at the inland
  side of the Unit 3 reactor building and 100mSv/h at the inland side of
  the Unit 4 reactor building.
- We will continue to take all measures to ensure the safety and to 
  continue monitoring the surrounding environment aroud the Power Station.
