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.
 
*The updates are 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 before the earthquake)
 
*With regard to the thermometer placed at the lower part of RPV (top of 
 the lower head 135°)  whose trend which showed a different trend while 
 others showed the increasing trend after we decreased the water injection 
 rate to the Unit 2 Reactor from the feed water system on February 22, we 
 reported to Nuclear and Industrial Safety Agency of Ministry of Economy, 
 Trade and Industry. We will continue monitoring this thermometer.
 ·At 11:00 am on March 4, the temperature of the lower part of the RPV 
  (top of the lower head 135°) : approx. 43.7 °C 
 ·At 11:00 am on March 4, the temperature of the lower part of the RPV 
  (top of the lower head 270°) : approx. 41.0 °C (reference) 
 
·Fukushima Daini Nuclear Power Station: 
 Units 1 to 4: shutdown due to the earthquake
 
·Kashiwazaki Kariwa Nuclear Power Station:
 Units 6: under normal operation
 (Units 1 to 5 and 7: outage due to regular inspections)

[Thermal Power Station] 
·Power supply has returned to normal and the facilities damaged by the 
 earthquake are now being handled in a timely manner.

[Hydro Power Station] 
·Power supply has returned to normal and the facilities damaged by the 
 earthquake are now being handled in a timely manner.

[Impacts on Transmission Facilities] 
·Power supply has returned to normal and the facilities damaged by the 
 earthquake are now being handled in a timely manner.

[Impacts on Power Supply and Demand Balance] 
We expect to maintain stable power supply in March.
Daily supply and demand balance is announced at our "TEPCO Electricity 
Forecast".
