associated with decommissioning and contaminated water as the whole
Government rather than counting solely on the operator.

Vice chair : Minister of METI
Member : Relevant Ministers
• The NRA Chairman was also invited as a top of the regulator to
provide advice from the scientific and technical standpoints, but not
to participate in the decision making.

treated water into the sea was established in April 2021 at this Council.
