Status of TEPCO's Nuclear Power Stations after the Tohoku-Chihou-Taiheiyou-Oki Earthquake (Daily Report as of 3:00 PM, November 21)
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).
