【Abstract】 The graphite is the main and key raw material for the preparation of spherical fuel element in high temperature gas cooled reactor. Nuclear grade graphite powder for spherical fuel element in high temperature gas cooled reactor includes natural graphite powder and artificial graphite powder. The microstructure profoundly affects the physicochemical properties of powder, which further affects the processing technology of matrix graphite powder and spherical fuel element. In this paper, the characteristics, microstructure and preparation technology of nuclear grade natural graphite powder and artificial graphite powder for spherical fuel element of high temperature gas cooled reactor are introduced in detail.更多还原
