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 on March 1. We will continue monitoring this 
  thermometer. 
  · At 11:00 am on March 7, the temperature of the lower part of the RPV 
    (top of the lower head 135°) : approx. 42.4 °C 
  · At 11:00 am on March 7, the temperature of the lower part of the RPV 
    (top of the lower head 270°) : approx. 40.3 °C (reference) 
 
- On March 7, we conducted dust sampling at Unit 2 Reactor Building Opening 
  (Blowout panel). 
 
- On March 7, we conducted sampling at the charcoal filter and particulate 
  filter of Unit 1 RCV gas control system. 
 
- At 1:48 pm on March 7, we started transferring accumulated water from the 
  basement of Turbine Building of Unit 3 to Centralized Waste Treatment 
  Facilities (Process Main Building) 
 
- At 1:55 pm on March 7, we started transferring accumulated water from the 
  basement of Turbine Building of Unit 2 to Centralized Waste Treatment 
  Facilities (Process Main Building) 
 
· Fukushima Daini Nuclear Power Station: 
  Units 1 to 4: shutdown due to the earthquake 
 
- At around 1:55 pm on March 7, at the first basement of Heat Exchanger 
  Building* of Unit 1 (non controlled area) a partner companies' worker 
  found another worker who was engaged in repair work of insulation 
  material of piping was lying. After that, at 2:36 pm on the same day, we 
  requested the helicopter emergency medical service (called "Doctor Heli"). 
  The worker retained consciousness and suffered no external injury. In 
  addition, we confirmed no radioactive materials were adhered to the 
  worker's body 
  * Heat Exchanger Building: The building installed heat elimination 
    facility by using seawater or coolant water. 
 
· 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".
