Abstract
Thermal expansions of the stoichiometric actinide dioxides (ThO 2 , UO 2 , NpO 2 and PuO 2 ) were investigated between room temperature and 1300 K using a high temperature X-ray diffraction method. The lattice parameter of NpO 2 at high temperatures was expressed as α T (pm) = 542.03 + 4.28 × 10 −3 T + 9.07 × 10 −7 T 2 − 1.36 × 10 −10 T 3 . Based on excellent reproducible data, thermal expansion of NpO 2 was determined. Thermal expansions of the other actinide dioxides showed good agreement with the respective recommended literature values. The linear thermal expansion coefficients ( α ) of actinide dioxides calculated at 1200 K were in inverse relation to their melting points. At room temperature, however, the α value of UO 2 was found to be higher than those of the other actinide dioxides and this result was discussed.
