The term "Nuclear Ceramics" means ceramics which are applied for fission and fusion nuclear reactors. This facilities was established for basic researches of nuclear ceramics. A series of high performance experimental equipments are installed into the radiation control area. Main equipments include high-resolution electron microscopy(see above photograph) for observation of crystalline defects induced into materials, X-ray diffractometer for lattice parameter measurement and phase identification, Laser-flash type thermal property measurement unit, mechanical testing machine, scanning electron microscopy, Oxygen-Nitrogen analyzer, et al. The researches on radiation damage of ceramics for low activation application, development of materials for severe environments, relation between crystalline defects and macroscopic properties, development of new materials using radiation effects, are now going on.
