TN approximation to neutron transport equation and application to critical slab problem

Journal of Quantitative Spectroscopy and Radiative Transfer, 2006
Abstract The critical slab problem has been studied in one-speed neutron transport equation with isotropic scattering by using the T N method. T N moment criticality solutions are obtained for the uniform finite slab using Mark and Marshak type vacuum boundary conditions. Results obtained by T N method, using the two type boundary conditions

Application of the HN method to the critical slab problem for reflecting boundary conditions

Journal of Quantitative Spectroscopy and Radiative Transfer, 2004
Abstract The recently developed H N method is used to solve the critical slab problem for a slab which is surrounded by a reflector. In the special case for R =0 (the reflection coefficient) the problem reduces to the one under vacuum boundary conditions. It is shown that the method is concise and leads to fast converging numerical results. The

U[sub N] Method For The Critical Slab Problem In One-Speed Neutron Transport Theory

AIP Conference Proceedings, 2008
The Chebyshev polynomial approximation (UN method) is used to solve the critical slab problem in one‐speed neutron transport theory using Marshak boundary condition. The isotropic scattering kernel with the combination of forward and backward scattering is chosen for the neutrons in a uniform finite slab. Numerical results obtained by the UN method are

One speed criticality problems for a bare slab and sphere: Some benchmark results – II

Annals of Nuclear Energy, 2007
Abstract Benchmark results for the two canonical problems of critical slab and sphere are reported. Three different approaches, use of the X-function and Neumann iteration, FN method, and discrete-ordinate method, are explored. It is found that to the orders of the approximations considered here, the critical half-thickness and critical radius values
