Countermeasures to Manage Contaminated Water
Water for cooling fuel debris touches that debris, and thereby becomes highly contaminated water containing highly concentrated radioactive materials.
New contaminated water is generated due to mixing of this highly contaminated water with groundwater and rainwater that flow into buildings.

- Monitoring information of environmental radioactivity levels (NRA)
- Radiation levels in the prefecture (Fukushima Prefecture)
Efforts made for decommissioning
What is decommissioning of the Fukushima Daiichi Nuclear Power Station?
Efforts are focused primarily on the following 4 types of work.
Decommissioning will be carried out safely and steadily over 30 to 40 years
