Comparison of rebalance stabilization methods for two-dimensional transport calculations

OSTI ID:6583395
It has been shown that stability in deep-penetration transport problems could be ensured, at least for some conditions, by adding fictitious boundary flows at each boundary. Extension of this work to general multidimensional problems has led to several interpretations. Three of these interpretations are compared, and a sound basis for the generalization is shown. Results of neutron transport calculations are given for several cases: neutron transmission along an annular gap surrounding a sodium-filled pipe that penetrates a thick concrete wall; a fast critical assembly problem; a neutron-source-in-a-corner problem; and a reactor head compartment problem. 4 figures, 3 tables.
