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 nuclear power stations (Fukushima Daiichi and Fukushima Daini).

* The updates are underlined.

[Fukushima Daiichi Nuclear Power Station]
・Unit 1 to 3: shut down due to the earthquake
・Unit 4 to 6: outage due to regular inspections before the earthquake

* At 9:30 am on April 10, we started transferring of accumulated water from the Site Banker Building to the Process Main Building at the Centralized Radiation Waste Treatment Facility. At 4:52 pm on the same day, we stopped transferring.

* At 10:00 am on April 10, we started transferring of accumulated water from the basement of T/B of Unit 6 to the temporary tanks. At 4:00 pm on the same day, we stopped transferring. At 10:00 am on April 11, we started transferring.

* At 9:26 am on April 11, we started transferring of accumulated water from the basement of T/B of Unit 2 to the Centralized Radiation Waste Treatment Facility (Miscellaneous Solid Waste Volume Reduction Treatment Building [High Temperature Incinerator Building]).

* At 2:47 pm on April 11, we started operation of the spent fuel pool desalting facility of Unit 3 since no problem was found as a result of trial operation.
