2 Accident-tolerant fuel claddings (ATFC) The breakthrough to the challenge facing nuclear fuels of LWR after Fukushima Dai-ichi accident involves the development of accident-tolerant fuels. Fukushima accident New requirements have been emerged on the performance of fuel to provide a more extended safety margin. One of the research efforts to enhance the accident-tolerance of nuclear fuels relies on the improvement in the oxidation resistance of claddings with the reduction of hydrogen emission. Hydrogen explosion Zr + 2H 2 O ZrO 2 + 2H 2 2

3 Technical issue Technical issues to development of ATFC Normal operation condition - High burn-up (higher corrosion/creep resistance) - Load follow (higher strength/fatigue resistance) Zr-based alloys Accident condition - High temperature oxidation (lower oxidation rate) - High temperature ballooning (higher creep/deformation resistance) Surface modified Zr alloys - Zr alloy + surface alloying, coating Hybrid materials - Zr alloy + thermo-stable materials (SiC, Nb, Mo ) Full ceramic materials - SiC/SiC f composite - Others (?) Increasing challenges - Fabrication - Economy - Verification Time to development 3

4 Challenges to ATFC Application of new materials raises many issues on the performance and the integrity of the claddings. - Oxidation resistance - Adhesion to the matrix - Phase stability up to high temp. - Thermal expansion coefficient - Neutron economy - Thermal conductivity - Irradiation susceptibility - Tube fabricability - Unknowns Zr alloys Surface modification 4

20 Summary Coating techniques both the coating methods and coating materials to reduce the oxidation rate of zirconium-based alloy in a high-temperature steam environment were studied. After 1200 o C test in steam environment, the SiO 2 showed the highest oxidation resistance among the tested materials, and Si was more effective than Cr from the viewpoint of oxidation resistance. Plasma spray (PS) and laser beam scanning (LBS) after a PS were selected as the coating method, and the Si was chosen as a coating layer for the surface coating material on zirconiumbased alloy. PS coating technique has problems such as the formation of pores in the Si-coated layer and the interface oxidation caused by low adhesion property. By the LBS treatment, the pores in the Si-coated layer by PS were successively removed, and the interface oxidation was suppressed by the formation of the diffusion bonding between substrate and Si-Zr mixed layer. Oxidation resistance of the Si-Zr mixed layer is superior to that of, and a good adhesion property can be obtained. Thus, the hydrogen generation of zirconium alloy by an excess oxidation reaction in a high-temperature steam environment can be considerably reduced by the application of the Si coating technology of PS + LBS treatments. 20
