摘要：
The thermal conductivities of heterogeneous mixtures of americium oxides and inert-matrix materials are computed. In the case of americium-oxide inclusions with a random shape the Finite Element Method (FEM) has been used and in the case of inclusions with a spherical shape an analytical equation has been used. The influence of fission product-induced damage to the inert matrix on the temperature distribution and on the overall thermal conductivity has been modelled for various sizes of the fissile particles.
