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 the level of reactor coolant had dropped 
  and the reactor pressure had increased because the Reactor Core 
  Isolation Cooling System stopped. Measures were 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 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. 
- We completed receiving electricity from the external transmission line  
  up to the auxiliary transformer. We are installing the power cable from  
  that transformer to the temporary power panel. 
- We have been injecting sea water into the reactor pressure vessel.

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.
- At 8:30AM on March 16th, fog like steam was confirmed arising from the 
  reactor building.
- At approximately 6:15AM on March 17th the pressure of the Suppression 
  Chamber has temporarily increased.
- We are working on receiving external power supply to Units 3 and 4. 
- 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. 
- At this moment, we do not consider any reactor coolant leakage inside 
  the reactor containment vessel happened.

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

Unit 6 (outage due to regular inspection) 
- Reactor has been shut down and the sufficient level of reactor coolant 
  to ensure safety is maintained.
- We are working on receiving external power supply to Units 5 and 6. We  
  completed the repair work on the emergency diesel generator (A). 
- At this moment, we do not consider any reactor coolant leakage inside 
  the reactor containment vessel happened.
 
Cooling of spent fuel pools
- In Unit 3, water discharge by Self-Defense Force's helicopters was 
  conducted from 9:48 AM in the morning on March 17th. Also water 
  discharge by the riot police's high-pressure water cannon trucks and 
  Self-Defense Force's fire engines was conducted from 7PM on March 17th 
  and finished at 8:09PM.
- In Unit 3, water discharge by Self-Defense Force's fire engines and US 
  army's fire engines was conducted from 2 PM and completed a quarter to 
  3 PM.
- After that, from 0:30 AM, Mar 19th, water discharge by Tokyo Fire  
  Department's Hyper Rescue was conducted and completed at 1:10 AM. 
- We are considering further water discharge at Unit 3 and others subject 
  to the conditions of spent fuel pools.

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.
  · Determined at 4:17 PM Mar 12th (Around Monitoring Post 4 )
  · Determined at 8:56 AM Mar 13th (Around Monitoring Post 4 )
  · Determined at 2:15 PM Mar 13th (Around Monitoring Post 4 )
  · Determined at 3:50 AM Mar 14th (Around Monitoring Post 6 )
  · Determined at 4:15 AM Mar 14th (Around Monitoring Post 2 ) 
  · Determined at 9:27 AM Mar 14th (Around Monitoring Post 3 ) 
  · Determined at 9:37 PM Mar 14th (Around main entrance ) 
  · Determined at 6:51 AM Mar 15th (Around main entrance ) 
  · Determined at 8:11 AM Mar 15th (Around main entrance )

- 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 15th, 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 found no signs of abnormal situation for the casks by visual 
  observation during the patrol activity. A detailed inspection is under 
  preparation.
- We will continue to take all measures to ensure the safety and to 
  continue monitoring the surrounding environment aroud the Power Station.
