UO2-BeO high thermal conductivity pellets have the characteristics of high thermal conductivity, high efficiency, long cycle and low recovery cost compared with traditional nuclear fuel. In this paper, the thermal diffusion coefficient of UO2-BeO pellets is characterized by laser flash method, in which the selection and optimization of test parameters are the main research part.
