Fuel debris retrieval challenges
There are various challenges pertaining to fuel debris retrieval which will reduce risks associated with the impact of radioactive substances on the surrounding environment.
- 1
The primary containment vessel is an extremely high-dose environment that cannot be entered by humans
- 2
The inside of the reactor building is a high-dose environment in which long periods of time cannot be spent working
- 3
Due to the reasons mentioned in 1 and 2 above, there are many unknowns pertaining to field conditions
- 4
The dispersion of radioactive substances must be suppressed when opening the primary containment vessel
- 5
Avoid criticality caused by a change in the field debris state
- 6
Formulate plans for relocating and storing the large amount of contaminated structures and waste
