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 
 Eearthquake
 (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). At around 2 pm on October 
  24, we confirmed at the site that there were oil film in the water 
  accumulated in the oil retaining wall and the oil was accumulated in the 
  space which the water in the oil retaining wall spilled. From these 
  reasons, we assumed that the oil observed on October 23 was the oil 
  which spilled from the oil retaining wall by inflow of rain water to the 
  wall. At this moment, we are investigating in detail, including nuclide 
  analysis for the water accumulated in the wall and analysis on the oil 
  film.

- 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. At 2:30 pm on the same day, we stopped the line connecting to 
  the water pump and started other water desalinations. At 4:20 pm, the 
  rated flow reached 50 m3/h. 

·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.
