A RAYLEIGH-RITZ PROCEDURE FOR DETERMINING THE FLUX AND THE CRITICAL LAPLACIAN OF ONE-GROUP DIFFUSION THEORY FOR HETEROGENEOUS REACTORS

Technical Report ·
OSTI ID:4256569
A Rayleigh-Ritz procedure for determining the flux and critical Laplacian of one-group diffusion theory is given for heterogeneous reactors. The procedure is used to determine the flux and the critical Laplacian for a bare slab when the Laplacian varies almost linearly across the slab. A comparison is made with Spinney's result for diffasion theory. The present method is completely general and can be applied to arbitrary distributions of fissile material. (auth)
