On April 17, TEPCO has announced the Roadmap towards Restoration from the Accident at Fukushima Daiichi Nuclear Power Station.
With regard to the accident at Fukushima Daiichi Nuclear Power Station due to the Tohoku-Chihou-Taiheiyo-Oki Earthquake that 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:
Step1. “Radiation dose is in steady decline” (our target is in about 3 months)
Step2. “Release of radioactive materials is under control and radiation dose is being significantly held down” (3 to 6 months after achieving Step1)
Step3. ” Target achievement dates are tentatively set as follows
3. Immediate Actions
Immediate actions were divided into three groups, namely, “I. Cooling”, “II. Mitigation”, “III. Monitoring and Decontamination.”
For the following five issues, targets are set for each of the five issues and various countermeasures will be implemented simultaneously.
“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”
[III.Monitoring and Decontamination]
“Measurement, Reduction and Announcement of Radiation Dose in Evacuation Order/Planned Evacuation/ Emergency Evacuation Preparation Areas”
