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).

[Fukushima Daiichi Nuclear Power Station]
·Unit 1 to 4: Abolishment (April 19, 2012)
·Unit 5 to 6: Outage due to regular inspections before the earthquake

-The mega float currently located in the shallow draft quay in the port will be moved to the north side of the port since all the transport crafts need to get to the shore for the construction to be carried out in the port and carry-in of equipment/materials. As the accumulated water transferred from Units 5-6 Turbine Buildings containing low level of radioactive materials is stored in the mega float, the accumulated water was transferred from the mega float to the temporary tanks installed near Units 5-6 on November 22 for the purpose of mitigating the risk of radioactive material leakage into the sea. At 4:55 PM on December 16, the transfer of the accumulated water has been completed. As the transfer of the residual water in the transfer pipeline was finished and all the preparation was completed, the mega float was removed off the dock at 8:45 AM on December 24 and was relocated and temporarily moored at approx. 270m north in the port at 12:30 PM.
