Calculation of heat capacity of the nuclear fuels UO2 and NpO2 using integer and non-integer n-dimensional Debye functions

WOS: 000295438300031 In the present study, the heat capacities of the nuclear fuels were computed using the series expansion relation for integer and non-integer n-dimensional Debye functions involving binomial coefficients and incomplete gamma functions. The proposed approach is novel as it uses the non-integer n-dimensional Debye functions for accurate calculations of the heat capacities C-V and C-P. The algorithm is used to simulate the variation of the heat capacities with temperature dependence of the nuclear fuels UO2 and NpO2. Analysis using computer simulation proved that the formula was in excellent agreement with the results reported in the literature. (C) 2011 Elsevier B.V. All rights reserved.
