Computer implementation of an analytical solution to the neutral particle Boltzmann transport equation for heterogeneous slabs, a benchmark poster

PDF Version Also Available for Download.

Description

An analytical solution to the neutral particle, isotropic down scatter Boltzmann transport equation is implemented for heterogeneous slabs and critical slabs using the F{sub N} method. The results of this implementation are compared to the ANISN/PC code, an S{sub N} solution method, in regions where S{sub N} codes fail. The flux distribution determined by ANISN/PC compare well to F{sub N} results for heterogeneous slabs even when ANISN/PC is being stressed. However, critical widths and fluxes do not compare well for critical slabs until ANISN/PC is used with a large angular quadrature and the number of secondaries is far away from ... continued below
