Issue Number:SFP-201
Phase: Design
Decommissioning Process Fuel Removal from SFP
Investigation Subject Confinement of radioactive materials
Issue Understanding of emission and leakage and their mitigating measures


① Taking measures to minimize emission and leakage (gas phase)

Desired state and reasons for it

For fuel retrieval from the SFP, structure dismantling and rubble removal are required. In this process, it is desirable to minimize the generation of dust.

Current state against ideal

A wet method has been already used for retrieval. In Unit 2 and Unit 1, removal of heavy equipment has been carried out by remote control.

Issues to be resolved

There are no issues that require investigation of new methods at this stage.
