To investigate the migration of seawater components to a spent fuel cladding tube, cross-sectional observation for spent fuel cladding tube immersed in diluted artificial seawater at 80 for 300 hours was conducted with EPMA. Spent fuel cladding tube having crud layer and zirconium oxide layer showed the adhesion of seawater components (Mg, Cl) on the cladding and no penetration of seawater components into the cladding.
