Discrete Ordinate Neutron Transport Equation for Two-Dimensional Triangular Geometry by Finite Fourier Transformation

摘要

Discrete ordinate neutron transport equation is derived for two-dimensional triangular regions by applying the finite Fourier transformation. Assuming that the angular flux on each side of a triangular region is constant and the source term is constant in a triangular region, a zero-th order discrete ordinate equation is derived. It is shown that in this equation, the angular flux can be obtained always positively, as long as the source is positive.
