With regard to the accident at Fukushima Daiichi Nuclear Power Station due
to the Tohoku-Chihou-Taiheiyo-Oki Earthquake occurred on Friday, March
11th, 2011, we are currently making our utmost effort to bring the
situation under control. This announcement is to notify the roadmap that
we have put together towards restoration from the accident.
1. Basic Policy
By bringing the reactors and spent fuel pools to a stable cooling
condition and mitigating the release of radioactive materials, we will
make every effort to enable evacuees to return to their homes and for all
citizens to be able to secure a sound life.
Based on the basic policy, the following two steps are set as targets:
"Radiation dose is in steady decline" as "Step 1" and "Release of
radioactive materials is under control and radiation dose is being
significantly held down" as "Step 2." Target achievement dates are
tentatively set as follows: "Step 1" is set at around 3 months and
"Step 2" is set at around 3 to 6 months after achieving Step 1.
3. Immediate Actions
Immediate actions were divided into three groups, namely, "I. Cooling",
"II. Mitigation", "III. Monitoring and Decontamination." For the
following five issues—"Cooling the Reactors," "Cooling the Spent Fuel
Pools," "Containment, Storage, Processing, and Reuse of Water Contaminated
by Radioactive Materials (Accumulated Water)," "Mitigation of Release of
Radioactive Materials to Atmosphere and from Soil," and "Measurement,
Reduction and Announcement of Radiation Dose in Evacuation Order/Planned
Evacuation/ Emergency Evacuation Preparation Areas"—targets are set for
each of the five issues and various countermeasures will be implemented
Please see the attachment for detailed actions.
We would like to deeply apologize again for the grave inconvenience and
anxiety that the broad public has been suffering due to the accident at
the Fukushima Daiichi Nuclear Power Station. We will continue to make
every endeavor to bring the situation under control.
