Press Release (Mar 12,2012)
Status of TEPCO's Facilities and its services after the Tohoku-Chihou-Taiheiyou-Oki Earthquake (as of 10:00 am, March 12)

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 were different 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 5:00 am on March 12, the temperature of the lower part of the RPV 
      (top of the lower head 135°) : approx. 42.0 °C 
    · At 5:00 am on March 12, the temperature of the lower part of the RPV 
      (top of the lower head 270°) : approx. 40.1 °C (reference) 
 
  * At 8:37 am on March 12, we started transferring the water accumulated 
    in the site banker building to the process main building in the 
    centralized waste treatment facilities. 
 
  * At 10:00 am on March 12, we started transferring the water accumulated 
    in the basement of Unit 6 Turbine Building to temporary tanks. 
 
· 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".
