Keywords:layered clay mineral hydrogels, radioactive dust

In this study, we examined prevention of radioactive dust during fuel debris retrieval work by coating debris with hydrogels. The physical and thermal properties were measured before and after the irradiation test. And we simulated a cutting test by using the simulated debris.
