Abstract: The thermal properties of Np- and Am-MOX solid solutions were investigated. The linear thermal expansion was investigated with high temperature X-ray diffraction from room temperature to 1973 K. No significant difference was observed between the Np and the Am doped MOX. The thermal conductivity of Am-MOX is about 10% higher than that of Np-MOX. The melting temperatures of Np-MOX and Am-MOX were measured using a laser heating setup and are equal to 3020 ± 30 K and 3005 ± 30 K, respectively.
