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 September 20, 
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.

*Updates are underlined.

[Nuclear Power Station]
- Fukushima Daiichi Nuclear Power Station:
    Units 1 to 3: shutdown due to the earthquake
    (Units 4 to 6: outage due to regular inspections) 

* It was confirmed that incorrect adsorption tower was installed in No.2 
  cesium adsorption instruments. At 9:47 pm on September 20, the instrument 
  was suspended when switching operation was given to the tower. At 10:02 pm, 
  the instrument was restarted and reached the regular water flow at 10:10 pm.

* At 10:00 am on September 21, we started transferring accumulated 
  underground water from the turbine building Unit 6 to temporary tank.

* At 11:40 am on September 21, as it was confirmed that water injection to 
  Unit 1 reactor was decreased. We adjusted the amount of water injection 
  to approximately 3.8 m3/h.

* At 11:40 am on September 21, as it was confirmed that water injection to 
  Unit 2 reactor by reactor water feed system was decreased. We adjusted 
  the amount of water injection to approximately 4.0 m3/h. The amount of 
  water injection by reactor core spray system was also adjusted to 
  approximately 4.0 m3/h.

* At 01:34 pm on September 21, water desalination instrument (reverse 
  osmosis membrane type) (3) was restarted by using backup system.

- 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.
