Application of the TN method to critical slab problem for one-speed neutrons with forward and backward scattering

Abstract

The critical slab problem which includes isotropic forward and backward scattering has been studied in one-speed neutron transport equation using first kind of Chebyshev polynomials. The critical half-thicknesses are computed for different degrees of c and forward and backward scattering with Mark and Marshak boundary conditions in the uniform finite slab. It is shown that T N method gives accurate results in one-dimensional geometry and the results are agreement P N approximation.
