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 4: Abolishment (April 19, 2012)
･ Unit 5 to 6: Outage due to regular inspections before the earthquake

-At 10:02 AM on November 19, we started transferring the accumulated water from Unit 4 Turbine Building basement to the Central Radioactive Waste Treatment Facility (Miscellaneous Solid Waste Volume Reduction Treatment Building [High Temperature Incinerator Building]).

-At 12:15 PM on November 19, the reactor injection amounts at Units 1-3 were changed as follows in order to reduce the load on the water treatment facility considering that there is a sufficient margin to the decay heat equivalent water injection amounts.
[Unit 1] Feed water system: Decreased from approx. 2.9m³/h to approx. 2.5m³/h, Reactor core spray system: Increased from approx. 1.9m³/h to approx. 2.0m³/h.
[Unit 2] Feed water system: Increased from approx. 1.7m³/h to 2.0m³/h, Reactor core spray system: Decreased from approx. 4.4m³/h to approx. 4.0m³/h.
[Unit 3] Feed water system: Increased from approx. 1.8m³/h to 2.0m³/h, Reactor core spray system: Decreased from approx. 4.5m³/h to approx. 4.0m³/h.

･ Unit 1 to 4: Shutdown due to the earthquake.
