Phase: Design
Decommissioning Process Dismantling PCV/RPV/Buildings
Investigation Subject Dismantling scenarios
Issue Establishing work sequence
Needs
① Establishing a dismantling work sequence
Desired state and reasons for it
To dismantle PCV/RPV/building efficiently and effectively, it is desirable to establish specific dismantling work sequences based on dismantling scenarios and waste sorting strategies.
Current state against ideal
As part of the waste sorting strategy, waste streams are being investigated for solid waste in Government-led R&D Program on Decommissioning, Contaminated and Treated Water Management.
In addition, it is planned to establish contamination surveys, demolition methods, and related measures for the implementation of demolition of the waste treatment buildings of Units 3 and 4, including the development of a building demolition model by fiscal year 2028.
Issues to be resolved
It is difficult to investigate the work sequence of dismantling without a certain degree of progress in investigating dismantling scenarios for Issue No. DRB-203.
