Abstract
We consider the steady multigroup neutron transport equation in a spatially periodic medium, with a spatially periodic source, and vacuum boundary conditions. We require (1) the ratio of a cell diameter to the diameter of the entire medium to be small, and (2) the transport operator to have N ≥ 1 eigenvalues which are small in magnitude, and simple. Then we show that the transport equation solution is approximated by the solution of an explicit system of N homogenized diffusion equations. We briefly discuss these equations and their properties.
Work performed under the auspices of the U. S. Energy Research and Development Administration.
