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
