Thermodynamic and thermophysical properties of the actinide nitrides

Uno, Masayoshi*; Nishi, Tsuyoshi; Takano, Masahide 

In a review "Comprehensive Nuclear Materials", we wrote the thermophysical and mechanical properties of actinide nitrides. In Chapter 1, the introductive remark was shown. In Chapter 2, the phase diagram and crystal structure of actinide nitrides were summarized. In Chapter 3, the melting or decomposition temperature, equilibrium vapor pressure, heat capacity, Gibbs free energy of formation and thermal conductivity of actinide nitrides were described, including recent experimental data obtained in JAEA. In Chapter 4, the mechanical properties of actinide nitrides and thermal expansion data obtained in JAEA were shown. On the other hand, the characteristic of nitride fuel and its historical development were not described because there appeared in another chapter of this review.
