Research Progress of FeCrAl Cladding Materials Strengthened by Particles for ATF

Since the Fukushima Daiichi accident in Japan, the safety of zirconium alloy as a nuclear fuel cladding material has been questioned. Therefore, the development of accident tolerant fuel (ATF) has been proposed by many countries in the world. FeCrAl alloy has become one of the important materials in the development of advanced ATF cladding materials due to its excellent resistance to high temperature steam corrosion. In this paper, the research progress of particles reinforced FeCrAl cladding materials for ATF is summarized from the aspects of composition design, preparation method and selection of reinforcing particles. The problems of particles reinforced FeCrAl cladding materials are pointed out.
