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:
  (Units 4 to 6: outage due to regular inspections) 

*At 8:54 am on October 3, the secondary cooling system piping arrangement 
 of circulating cooling system of Unit 4 spent fuel pool was stopped due 
 to the replacement of the secondary cooling system piping arrangement. 
 After completing the replacement, the secondary cooling system was 
 restarted at 3:03 pm on the same day.
*At 10:00 am on October 3, we resumed transferring accumulated water at 
 the basement of Unit 6 turbine building to a temporary tank. The transfer 
 was stopped at 4:00 pm on the same day.
*At 10:37 am on October 3, in Centralized Radiation Waste Treatment 
 Facility, we started transferring accumulated water at On-site Bunker 
 Building to Process Main Building. The transfer was stopped at 3:37 pm on 
 the same day.
*At around 3:00 pm on October 3, TEPCO staff observed an oil leakage from 
 the transformer B system for transportation of Okuma 3 line (in-vehicle) 
 while on patrol. The amount of the oil leakage was about one drop in ten 
 seconds and the oil formed an oil film of approximately 1m x 1m. An 
 emergency procedure was taken to stop the leakage. A further 
 investigation will be conducted, though the transformer can be used 
 without problems.

-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.
