A scanning electron microscope for micro-surface analysis of spent fuel

The examination of spent fuels and radioactive materials by using scanning electron microscope plays an important role in their development for energy systems as well as providing data for basic mechanism involved in corrosion, radiation damage fracture, etc. To conduct this type of work, the SEM was modified and installed in shielded glove box. The specimen of the spent fuel was made of conductive resin, and the specimen of the irradiated cladding tube was made of general resin. In the micro-surface analysis of the spent nuclear fuel, the spent nuclear fuel has many pore. In the micro-surface analysis of the irradiated cladding tube, also, the irradiated cladding tube has an oxide layer and hydride
