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 November 4, due to inspection of Unit 3 reactor water injection pump,
  it was switched to Unit 1/2 reactor water injection pump. At 3:13 pm,
  together with this switch, in regard with water injection to Unit 1
  reactor, water injection amount of feed water system was adjusted to
  approx.7.6 ㎥/h. In regard with water injection to Unit 2 reactor, water
  injection amount of feed water system was adjusted to approx.3.0 ㎥/h,
  and that of the reactor core spray system to approx.7.2 ㎥/h. In regard
  with water injection to Unit 3 reactor, water injection amount of feed
  water system was adjusted to approx.2.5 ㎥/h, and that of the reactor
  core spray system to approx.8.1 ㎥/h.

· At 10:00 am on November 4, we started transferring accumulated water 
  from On-site Bunker Building to Centralized Radiation Waste Treatment 
  Facility. At 3:29, the transfer was stopped.

· At 3:48 pm on November 4, 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.

· 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]
This winter, there will be some minus factors such as the regular 
inspection of Unit 5 at Kashiwazaki-Kriwa Nuclear Power Station. On the 
other hand, there will be several plus factors such as the recovery of 
the common thermal power stations which suffered the earthquake. As a 
result, we expect to secure 54.9 million kW (at the end of December), 
54.6 million kW (at the end of January), 53.7 million kW (at the end of 
February) supply power. 
Compared to the maximum demand in the last winter, which is 51.5 million 
kW, we will have 2.2 - 3.4 million kW generation reserve margin.

We expect to maintain stable power supply this winter, however, as there 
remains possibilities of unplanned shutdowns at our power stations and 
growth in the demand according to the rapid change in the temperature, we 
would like to ask your reasonable effort to save electricity. 

We will continue to make our efforts to maintain stable operation and 
maintenance of the power facilities in order to "prevent in principle" 
the planned blackouts and secure power supply.
