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) 

*From 8:05 am to 9:35 am on September 12, we conducted dust sampling at thev 
 upper part of reactor building of Unit 3 using a large crane vehicle.

*At 2:01 pm on September 12, we adjusted the rate of water injection to 
 Unit 3 reactor to approx. 4.0 m3/h through reactor feed water system (the 
 rate of water injection through core spray system remains unchanged, 
 approx.3.0 m3/h).

*At 11:30 am on September 12, we resumed transferring accumulated water 
 from the basement, T/B of Unit 6 to the makeshift tank.

*Around 10:00 am on September 12, we confirmed that indication of a movable 
 monitoring post was unreadable. The post had monitored the dose at the 
 main gate of the Power plant. The data transmission was resumed at 10:30 
 am on the same day.

*At 10:06 am on September 12, waste liquid discharge pump (B) in the 
 suppression pool water surge-tank (hereinafter called "SPT") stopped due 
 to overload. At 11:23 am on the same day, SPT waste liquid discharge pump 
 (A) was activated. After that, we inspected SPT waste liquid discharge 
 pump (B) and confirmed that there was no defect in the pump. At 11:53 am 
 on the same day, we restarted SPT waste liquid discharge pump (B) and 
 stopped SPT waste liquid discharge pump (A).

-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.

[Perspective of Power Supply and Demand Balance in this summer]
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.
