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 around 2 pm on October 23, TEPCO's employee found seemingly oil spill 
  outside the oil retaining wall of temporary oil tank for main transformer 
  in the power plant premise (Wild Bird Forest). The detail is under 
  investigation.

- At 10:35 am on October 22, we started transfer of the accumulated water 
  from the basement of Turbine Building of Unit 1 to the basement of 
  Turbine Building of Unit 2. At 9:07 am on October 24, we stopped transfer.

- At 9:18 am on October 24, transportation of accumulated water from the 
  basement of Turbine Building of unit 2 to Centralized Radiation Waste 
  Treatment Facility (Process Main Building) was stopped temporally by the 
  pumps change. After the pump changes, the transportation was re-started 
  at 9:34 am on the same day.

- At 10:00 am on October 24, we restarted to transfer the accumulated water, 
  which had been transferred from the turbine building of Unit 6 to the 
  temporary tank, from the temporary tank to Mega Float. At 11:30 am on 
  the same day, we stopped transfer.

- At around 11:30 am on October 24, we observed the water leakage (about 
  20 litters) from the axis seal region of the law water pump (for 2-1 
  skids use) which was a constitution apparatus of the Water Desalination 
  Facility (RO membrane unit) 2 of the water treatment system and we 
  stopped the facility. Afterward, the water leakage was confirmed to be 
  stopped.

· Fukushima Daini Nuclear Power Station: 
    Units 1 to 4: shutdown due to the earthquake

- At around 2:50 pm on October 17, we confirmed that a worker of partner 
  company who was engaged in cleaning inside of Primary Containment Vessel 
  of Unit 4 was exposed to radiation 1.58mSV, which is excess to the 
  planned radiation 0.9mSV. After the result of the investigation, we 
  guessed that the radiation administrator set the working time without 
  featuring the work of near the high radiation place, because he missed 
  the high radiation dose which was confirmed by pre- measurement. 
  Furthermore, the worker was not aware of the sound of his APD and kept 
  the work, since he had on his hood mask and was using a cleaner.

· 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.
