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 1:17 pm on October 26, we started cutting off the designated piping 
 after confirming that the hydrogen density inside the piping for cooling 
 in case of reactor shutdown was less than 0.1 %, as one of the 
 construction work to install gas monitoring system inside the Primary 
 Containment Vessel. At 3:15 pm on the same day, we finished cutting pipes. 
 After that, we conducted welding of blind plates of cut pipes and 
 covering holes of the pipes. At 7:00 pm on the same day, we finished all
 operations.
-At 9:47 am on October 26, for the water injection to the reactors of 
 Units 1 to 3, we switched from normal water injection line to emergency 
 water injection line, due to the shutoff of facilities for power source 
 reinforcement work. Along with the switching work, we adjusted the amount 
 of water injection from water feeding system to approximately 3.8 m3/h 
 for Unit 1's reactor. Likewise, we adjusted the amount of water 
 injection to Unit 2's reactor to approximately 3 m3/h from water feeding 
 system, and to approximately 8m3/h from Core Spray System. At 3:20 pm on 
 the same day, for Unit 3, we switched from emergency water injection line 
 to normal water injection line due to completion of power source 
 reinforcement work. At 4:10 pm on the same day, for Unit 1 and 2, we 
 switched the water injection line in like wise.
-On October 26, we replaced the hose for transferring reverse osmosis
 membrane concentrated water in Water Desalinations (reverse osmosis 
 membrane) that liquid spoil was found on October 8. 
-At 10:00 am on October 26, we started transferring the accumulated water 
 from the basement of turbine building of Unit 6 to the temporary tanks. 
 At 4:00 pm on the same day, we stopped the transfer.

·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.
