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)

* At around 8:30 on March 26, 2012, in the area of condensed water tanks for water desalinations (reverse osmosis membrane) of Fukushima Daiichi Nuclear Power Station, a partner company worker found that water was leaked from a pipeline (anti-pressure hose) which transferred the condensed water from the water desalinations to the condensed water tanks. In order to stop the water leakage, we stopped the transfer pumps of the water desalinations (reverse osmosis membrane) and then the leakage stopped. After that, we closed the valves at the both sides to the leakage point of the pipeline (anti-pressure hose). When we checked the leakage on the site later, we found that a part of the leaked water had been poured into a nearby drainage for general draining water. And then, we conducted sampling surveys on the leaked water, the water which was poured into the drainage, and the seawater around the exit of the drainage. As a result, we judged that some water including radioactive materials was poured into the sea from the exit of the drainage located at about 300 m south from the discharge channel of Unit 1-4 of Fukushima Daiichi Nuclear Power Station. At this moment, the water desalinations (reverse osmosis membrane and evaporative concentration apparatus) are not in service. However, because we have much treated fresh water, it does not affect water injection to the reactors.

* At 10:00 am on March 26, we started transferring of accumulated water from the basement of Unit 6 T/B to the temporary tank.

* At 10:10 am on March 26, we started transferring of accumulated water from the basement of Unit 3 T/B to 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 1 to 7: outage due to regular inspections
* Units 6: Under 10th regular inspection from March 26)

[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".
