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)

- On October 28, we completed the installation of cover panels which cover 
  the reactor building of Unit 1 to control emission of radioactive 
  materials.

- On October 28, we started the installation work of the water shielding 
  wall at the seaside in front of the existing seawalls of Units 1 to 4, 
  with the expectation of preventing further contamination in the ocean via 
  grounder water.

- At 4:10 pm on October 28, we adjusted the amount of water injected to the 
  reactor of Unit 1 to approx. 4.5 m3/h in order to improve the working 
  condition inside the covers at Unit 1 by holding down the evaporation 
  from the reactor.

- At 10:00 am on October 28, 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 4:00 pm on the same day, we stopped 
  the transfer.

- At 12:53 pm on October 28, we started up the exhaust fan of gas 
  management system of primary containment vessel in the reactor building 
  of Unit 2 and commenced commissioning. After we confirmed the stable 
  operation of the system, from 6:00 pm on the same day, we put the system 
  in operation.

- At around 2:20 pm on October 28, one of TEPCO's employee conducting 
  document check at administrative building has removed face mask when that 
  employee felt sick and vomit, We plan to conduct check the intake by 
  whole body counter. We have confirmed there was no contamination on the 
  face. After testing by the whole body counter, we evaluated that he did 
  not have intake of radioactive substances.

- At 8:30 am on October 29, two workers from the cooperating companies were 
  injured during dismantling of the large crane used to install the cover 
  for the Reactor Building, Unit 1 within the site boundary. One worker 
  will be transported to a hospital by an air ambulance, and the other 
  worker will be transported to the hospital by a company vehicle.

·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.
