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, 2011, we have compiled the roadmap towards restoration from the 
accident and on July 19 we accomplished the Step1 target "Radiation dose 
is in steady decline". Then on December 16 we confirmed the accomplishment 
of the Step 2 target "Release of radioactive materials is under control 
and radiation doses are being significantly held down".
In addition, on December 21, 2011, we have compiled the "Mid-to-long-Term 
Roadmap toward the Decommissioning of Fukushima Daiichi Nuclear Power Units 
1-4, TEPCO".
In addition to the maintenance of the plant's stable condition, we will 
implement Mid-to-Long Term countermeasures towards the decommissioning of 
Fukushima Daiichi Nuclear Power Units 1-4 to enable evacuees to return to 
their homes as soon as possible and reduce the anxiety of the people in 
Fukushima and the whole nation as soon as possible.

Below is the status of TEPCO's major facilities.

* Updates since the previous press release underlined. 

[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 10:04 am on January 9, because the replacement work of the water 
    injection piping arrangement from the water feed system in association 
    with the trial run of reactor injection pump in Turbine Building has 
    been completed, we have adjusted the amount of injected water to the 
    reactor gradually. For the amount of injected water to the reactor, 
    we adjusted water injection from the reactor feed water system from 
    approx. 1.7 m3/h to 3.0 m3/h, and water injection from the core spray 
    system for approx. 8.1 m3/h to 7.0 m3/h.

  - At 10:40 am on January 9, a water pond was found near the evaporative 
    concentration apparatus 2B (under suspension) of the water treatment 
    facility. The amount of the water is about 11 liter and is staying in 
    the dam. The leakage was from float type flow meter at vent condenser 
    spray line of evaporative concentration apparatus(*) and the amount 
    of leakage is about one drop in 6 seconds. After closing the valve of 
    the line, it was about one drop in 15 - 20 seconds. A dish will be 
    settled under the leakage. The water is purified one in evaporative 
    concentration apparatus (for water injection to the reactor). We 
    conduct nuclide analysis for the water of the line regularly and the 
    last result was as fallows: Β-ray is 6.0×10-1Bq/cm3 (November 29, 
    2011) and γ -ray is below measurable limit (December 20, 2011). 
    * Vent condenser spray line of evaporative concentration apparatus: 
      cooling the vapor (purified water) that is generated in the 
      evaporative concentration apparatus and supply water for injection 
      to the reactor.

  - At around 2:22 pm on January 9, at the Spent Sludge Storage Facility (*) 
    of Fukushima Daiichi Nuclear Power Station (1F), a partner company's 
    worker who had been engaged in concrete placement work reported his 
    physical disorder. He was carried to the emergency medical room of 1F's 
    Unit 5/6 and received medical treatment. Because he was in 
    cardiopulmonary arrest, he was carried from 1F to Iwaki Kyouritsu 
    Hospital at 3:25 pm. For reference, no radioactive materials were found 
    to be attached to the worker's body. 
    * Spent Sludge Storage Facility: The facility to store radioactive 
      waste (spent sludge), which is produced during the process of 
      accumulated water treatment, on a temporary basis. 

· 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.
