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 August 17, 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:
  Units 1 to 3: shutdown due to the earthquake
  (Units 4 to 6: outage due to regular inspections) 

*At 10:00 am on September 20, we restarted transferring accumulated water 
 in the basement of turbine building of Unit 6 to the temporary tanks. At 
 4:00 pm on the same day, we stop transferring.

*At approximately 11:00 am on September 20, a puddle of water was found at 
 the basement of common spent fuel pool. As a result of nuclide analysis of 
 the water, some radioactive materials (Cs 134: 4.7-7.0x100 [Bq/cm3], 
 Cs 137: 5.4-8.1x100 [Bq/cm3], Co 60: 1.2x100 [Bq/cm3]) were detected. 
 However we assume that there is no leakage outside because any pipeline 
 connecting to the outside does not exist. We are now investigating sources 
 of the influent water.

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

-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.
