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 15, the temperature of the lower part of the RPV 
    (top of the lower head 135°) : approx. 40.6°C 
  · At 5:00 am on March 15, the temperature of the lower part of the RPV 
    (top of the lower head 270°) : approx. 40.8°C (reference) 

* Accumulated water (volume: about 220 m3) in the trench located between 
  the process main building of Centralized Radiation Waste Treatment 
  Facility and Miscellaneous Solid Waste Volume Reduction Treatment 
  Building (High Temperature Incinerator Building) found on December 18, 
  2011 was transferred to Miscellaneous Solid Waste Volume Reduction 
  Treatment Building (High Temperature Incinerator Building) on December 
  23 in the same year (transfer volume: about 120 m3). Since then, the 
  water level has been monitored. Because the water level has been rising, 
  the accumulated water was started to be transferred to Miscellaneous 
  Solid Waste Volume Reduction Treatment Building (High Temperature 
  Incinerator Building) at 3:35 pm on March 14, 2012. The transfer was 
  stopped at 8:20 am on March 15, 2012 (transfer volume: about 120 m3). 

* At 10:00 am on March 14, we restarted transferring accumulated water on 
  the basement of Turbine Building of Unit 6 to the temporary tank. At 
  4:00 pm on the same day, we stopped the transfer. At 10:00 am on March 
  15, we restarted the transfer. 

* As installation works of the PCV gas control system of Unit 3 was 
  completed, we started a test operation at 11:38 am on February 23. We 
  confirmed that an exhaust flow amount was stable at 33m3/h at 2:10 pm 
  and started an adjustment operation. As the result of the adjustment 
  operation, we confirmed no significant problem with the gas control 
  system. Therefore, the operation mode was switched from the adjustment 
  mode to the regular mode at 7:00 pm on March 14. 

* At 8:09 am on March 14, in order to investigate soundness of the 
  transfer line from Centralized Radiation Waste Treatment Facility 
  (Process Main Building) to cesium absorption instrument No.2, that was 
  newly settled to enhance security in the water treatment system, cesium 
  absorption instrument No.2 was suspended. After its trial run, no 
  significant problem with the instrument was confirmed. Therefore the 
  transfer line was switched and the instrument was started at 7:32 pm on 
  the same day. The treatment of the accumulated water at the process main 
  building of Centralized Radiation Waste Treatment Facility 
  (Miscellaneous Solid Waste Volume Reduction Treatment Building "High 
  Temperature Incinerator Building") was restarted. At 7:39 pm, the 
  constant flow status was attained (approximately 42m3/h). 

* At 8:46 am on March 15, we started transferring accumulated water on the 
  basement of Turbine Building of Unit 3 to the process main building of 
  Centralized Radiation Waste Treatment Facility (Miscellaneous Solid 
  Waste Volume Reduction Treatment Building "High Temperature Incinerator 
  Building"). 

·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".
