Abstract

In this presentation, we consider the work of V.M. Shmakov [1] concerning the two stream (back and forth) monoenergetic 1D transport approximation in a critical spherical reactor. The primary focus of Shmakov's work is the development of a simple analytical neutron transport model to serve as a benchmark to provide a high quality, straightforward numerical comparison to Monte Carlo. The formulation differs from diffusion theory in that there is no diffusion of neutrons streaming away from and toward the spherical center. Curiously, however, a mathematically equivalent diffusion equation completely analogues to diffusion in plane geometry emerges. Nevertheless, the physical contexts are different. The mathematical equivalence however does enable an extension of Shmakov's model to heterogeneous media.
