The FN method for solving the critical problem for a slab with a finite reflector
Annals of Nuclear Energy, 1980Abstract The F N method is used to solve the critical problem for a slab reactor with a finite reflector. Numerical results for the critical thickness are shown for different values of the mean number of secondary neutrons per collision and reflector thickness using various orders of the F N approximation.

Benchmark results for the critical slab and sphere problem in one-speed neutron transport theory
Annals of Nuclear Energy, 2011In this paper benchmark numerical results for the one-speed criticality problem with isotropic scattering for the slab and sphere are reported. The Fredholm integral equations of the second kind based on the Case eigenfunction formalism are numerically solved by Neumann iterations with the Double Exponential quadrature.

The reflected critical slab problem for one-speed neutrons with strongly anisotropic scattering
Kerntechnik, 2008Abstract The Chebyshev polynomial approximation is used to solve the reflected critical slab problem for one-speed neutrons in a slab with strongly anisotropic scattering. The scattering kernel which is a combination of backward-forward-isotropic scattering and linearly anisotropic scattering is chosen in a uniform finite slab.

The critical slab problem for reflecting boundary conditions in one-speed neutron transport theory
Annals of Nuclear Energy, 1996Abstract The critical slab problem based on the singular eigenfunction method solution is generalized using one-speed neutron transport theory. Changing vacuum boundary to reflective boundary, a slab is investigated to rederive the criticality conditions when both reflection coefficients are the same in both surfaces.

Abstract A singular eigenfunction approach is used to solve the classical slab and the sphere criticality problems. This approach is based on the use of the infinite medium Green's function which is obtained by the method of elementary solutions in the C N equations, that is in the third form of the transport equation.

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 ...
