Containing, transportation and storage of retrieved fuel debris
R&D efforts (Application development linked to plant applications and actual use)
Ongoing projects
Development of Technology for Containing, Transportation and Storage of Fuel Debris(Project of Decommissioning and Contaminated Water Management)
Summary
In order to establish a scenario for the process from fuel debris retrieval to its storage, system shall be developed for safe, secure and reasonable containment, transportation and storage of retrieved fuel debris.
Action items
- Development of technology for handling of powdery and slurry/sludge state fuel debris
① Advancement of Prediction Method of Hydrogen Generation
② Establishment of countermeasures for hydrogen gas accumulation based on hydrogen gas release behavior - Technology development for maintaining the stable storage of fuel debris
- Re-evaluation of storage methods and storage canisters
