Numerical simulation of multiconstituent diffusion and helium release characteristics of the /sup 238/PuO/sub 2/ heat source used in radioisotopic thermoelectric generators
An analytical model is described that was developed to simulate multiconstituent diffusion within a heat source sphere, helium generation within a heat source sphere, and helium release from the surface of a heat source sphere into the surrounding environment. The model represents the first attempt to simulate multiconstituent mass transport using the continuum thermomechanical theory of mixtures and demonstrates that this theory is a viable alternative to irreversible thermodynamics.
