Press Release (Oct 07,2011)
Status of TEPCO's Facilities and its services after the Tohoku-Chihou-Taiheiyou-Oki Earthquake (as of 3:00 pm, October 7)
Due to the Tohoku-Chihou-Taiheiyou-Oki Earthquake which occurred on March 
11, 2011, TEPCO's facilities including our nuclear power stations have 
been severely damaged. We deeply apologize for the anxiety and 
inconvenience caused.
With regard to the accident at Fukushima Daiichi Nuclear Power Station, on 
April 17, we have compiled the roadmap towards restoration from the 
accident and then we updated the progress status of roadmap considering 
the current situation, on July 19. Accomplishment of the Step1 target 
"Radiation dose is in steady decline" has been confirmed. On September 20, 
we updated the further progress. 
By bringing the reactors and spent fuel pools to a stable cooling 
condition and mitigating the release of radioactive materials, we will 
make every effort to enable evacuees to return to their homes and for all 
citizens to be able to secure a sound life.

Below is the status of TEPCO's major facilities.

*Updates are underlined.

[Nuclear Power Station] 
-Fukushima Daiichi Nuclear Power Station Unit 1 to 3: shut down due to 
 the earthquake
  (Units 4 to 6: outage due to regular inspections) 

*From 2:06 pm on October 7, in order to prevent from spontaneous 
 combustion of cut trees and dust dispersing we started to sprinkle water 
 in the site of Fukushima Daiichi Nuclear Power Station with cleared-up 
 accumulated water of Unit 5 and 6. We measured radioactivity density in 
 advance and confirmed to meet requirement of the guideline suggested in 
 "Guideline regarding radioactive materials on bathing area". 
*From 11:44 am to 2:03 pm on October 7, we conducted dust sampling at 
 Opening section for equipment hatch and truck bay door of Unit 1 Reactor 
 building.
*As confirming downward tendency on flow rate at Residual Heat Removal 
 system sea water pump (C) of Unit 6, we stopped cooling reactor by 
 Residual Heat Removing system (A) and conducted check-out the pump and 
 related system at 11:55 am on October 7. The result of check-out , we 
 confirmed no abnormalities and restarted cooling reactor with Residual 
 Heat Removal system (A) at 12:41 pm on the same day. 
*At 10:00 am on October 7, we started transferring accumulated water at 
 basement of Unit 6 turbine building to temporary tank.

-Fukushima Daini Nuclear Power Station: 
  Units 1 to 4: shutdown due to the earthquake

*At 11:25 am on October 7, we stopped Residual Heat Removal system (B) 
 regarding switching work from Residual Heat Removal system (B) to (A), 
 and started operation of Residual Heat Removal system (A) at 11:42 am on 
 the same day.     

-Kashiwazaki Kariwa Nuclear Power Station:
  Units 5, 6: under normal operation
  (Units 1 to 4 and 7: outage due to regular inspections)

[Thermal Power Station]
-Power supply has returned to normal and facilities damaged by the 
 earthquake are now being handled in a timely manner.

[Hydro Power Station]
-Power supply has returned to normal and facilities damaged by the 
 earthquake are now being handled in a timely manner.

[Impacts on Transmission Facilities]
-Power supply has returned to normal and facilities damaged by the 
 earthquake are now being handled in a timely manner.

[Impacts on Power Supply and Demand Balance]
Thanks to our all customer's energy-saving efforts, we could successfully 
maintain an even supply-demand balance in this summer. We express our 
deepest appreciation to the efforts.

While we will continue to exert maximum effort to stabilize the 
supply-demand balance, we kindly request your continued efforts in keeping 
electricity consumption within reasonable levels.
