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 10:10 am on January 11, due to the preparation of inspection of the 
   Primary Containment Vessel(PCV) of Unit 2, we adjusted the amount of 
   nitrogen injected to the PCV from 13m3/h to 10m3/h to reduce the 
   pressure of the inside. 

 - At 10:18 am on January 11, because of the replacement work of the water 
   injection piping arrangement from the water feed system in association 
   with the commissioning of reactor injection pump in Turbine Building of 
   Unit 3, we have controlled the amount of injected water to the reactor 
   gradually. The amount of injected water to the reactor of Unit 3 from 
   the reactor feed water system was adjusted from approx. 1.9 m3/h to 
   approx. 1.0 m3/h, and the amount from the core spray system was 
   adjusted from approx. 7.0 m3/h to approx. 8.0 m3/h. 

 - 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.
   At around 1 pm on January 11, we were reported from the partner company 
   that his death was confirmed by a doctor at 5:02 pm on January 9. 
   * 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.

 - At 2:39 pm on January 11, to protect the decline of facilities which 
   are needed to maintain the stable cold shutdown and improve the 
   high-humidity environment in the Reactor Building of Unit 5, we started 
   up ventilation and air-conditioning system in the building. This air 
   conditioning system inlet and outlet air by high-efficiency particle 
   filter.

 - Because of the finding of accumulated water included radioactive 
   materials at the trench between the Process Main Building and the 
   Miscellaneous Solid Waste Volume Reduction Treatment Building[High 
   Temperature Incinerator Building](December 18, 2011), we started the 
   inspection of other trenches at the site on January 11.

· 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.
