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) 

* At 9:46 am on September 30, we stopped transferring accumulated water
  from Unit 3 turbine building basement to Centralized Radiation Waste
  Treatment Facility (Process Main Building). At 10 am on the same day, we
  resumed the transfer to Centralized Radiation Waste Treatment Facility
  (Miscellaneous Solid Waste Volume Reduction Treatment Building [High
  Temperature Incinerator Building]).
* At around 10:30 am on September 30, we resumed transferring accumulated
  water from Unit 6 turbine building basement to temporary tanks.
* At 10:20 am on September 29, we stopped the desalination instrument 
  (RO type) (2) as water leakage from the flange connection of 
  transferring horse of concentrated water side was confirmed. At 10:45 am 
  on the same day, we confirmed stop of water leakage after stop of the 
  instrument. At 11:40 am on the same day, we restarted the instrument by 
  using another system different from the one that leaked out of 2 systems 
  of process lines. At 11:27 am on September 30, the leaked flange
  connection was replaced so that the leaked system was resumed.
* On September 30, as the repair work for the outlet valve of Unit 5
  Residual Heat Removal System Sea Water Pump completed, between 11:30 am
  and 11:34 am on the same day, the Residual Heat Removal System was
  switched from A system to B (the Residual Heat Removal System Sea Water
  Line was also switched from A system to B).
* At 2:19 pm on September 30, the oil separator treated water transfer
  pump was tripped due to overload so that the Cesium adsorption apparatus
  also tripped. The cause of the overload is currently under investigation.
* At 3 pm on September 30, in order to add transformer control panel as
  power supply for works related Unit 3, the power supply for Spent Fuel
  Pool Cooling was temporary stopped.

-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.
