ALPS treated Water Q&A
Here, we will answer the questions of ALPS-treated water.
If you have questions, please check the answer!
＜Handling of the treated water＞
Q3: Why is disposal of ALPS treated water needed?
Q4: Why are two options suggested by the expert committee feasible?
Q5: Is it possible to store or discharge treated water outside of Fukushima Daiichi NPS (FDNPS)？
Q6: Is it possible to store in intermediate storage facilities?
Q7: What are the steps toward the handling of treated water?
＜Characteristics of the treated water＞
Q8: What is tritium?
Q9: Can tritium be removed?
Q10: Does the treated water contain radioactive materials other than tritium?
＜Radiation impact of the treated water＞
Q11: How much is the radiation impact of treated water release?
Q12: What regulatory standards are applicable to the discharge from Fukushima Daiichi NPS (FDNPS)？
＜Countermeasures for possible reputational damage＞
Q13: What kind of countermeasures will be taken for possible reputational damage?

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.
- Observation data, Fukushima Daiichi NPS (TEPCO)
- 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
