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 October 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.

*The underlined parts are the updates from the previous press release.

[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)

-At 9:55 am on October 27, we switched water injection line of unit 1 and 
 2 from normal water injection line to emergency water injection line to 
 add the vane to adjust flow amount of water injection line to the Unit 
 2's reactor in order to improve the ability to control the water 
 injection amount. At 2:35 pm on the same day, we switched from emergency 
 water injection line to normal water injection line due to completion of 
 the work. Injection amount is stable after the work.
-At 10:00 am on October 27, we started transferring low-level accumulated 
 water to Mega Float from a temporary tank where we had transferred from 
 the turbine building of Unit 6.
-At 10:30 am on October 27, we conducted leak test of the system as a part 
 of construction to settle the gas control system of Primary Containment 
 Vessel at the reactor building of Unit 2. As a result, we confirmed 
 in-leak volume to the system had no problem. In addition, we conducted 
 tentative operation test. As a result, we confirmed operational aspect of 
 electric heater and exhaust fun had no problem.
-At 1:30 pm on October 27, we started injection of hydrazine to spent fuel 
 pool of Unit 3 through the circulating cooling system. At 3:08 pm on the 
 same day, we stopped injection of hydrazine. 

·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.
