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 November 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 3:33 pm on November 18, we adjusted flow rate of injecting water of 
  reactor of Unit 1 at approx. 5.5m3/h before the addition of water 
  injection line from Core Spray System in order to enhance security of 
  water injection.

- At 3:33 pm on November 18, along with the adjustment of water injection 
  amount of Unit 1, we adjusted the amount of water injection to the 
  reactor of Unit 2 to approximately 3.1 m3/h from water feeding system, 
  and to approximately 7.1 m3/h from Core Spray System. Also we adjusted 
  the amount of water injection to the reactor of Unit 3 to approximately 
  2.5 m3/h from water feeding system, and to approximately 8.1 m3/h from 
  Core Spray System.

- At around 4:10 pm on November 18, water leakage of one drop in 3 
  seconds was confirmed from pressure hose connecting point of absorption 
  side of emergency feed water injection pump located upland of Unit 1. 
  The before and after valve was closed and isolated, and the procedure to 
  receive the drop by saucer was taken. And we confirmed the radiation 
  dose in ambient air near the leaking point was not specifically 
  different from surrounding area. There was no change in the injection 
  amount due to this work because the pump is for emergency feed water 
  infection and that is not operating at the preset time. We are planning 
  to change the hose later.

·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-Kariwa 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 GW (at the end of December), 54.6 GW (at the end 
of January), 53.7 GW (at the end of February) supply power. 
Compared to the maximum demand in the last winter, which is 51.5 GW, we 
will have 2.2 - 3.4 GW 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.
