A Study to increase an accuracy of multi-group library for reactor calculations

Chiba, Go; Okumura, Keisuke

In order to increase an accuracy of reactor calculations with multi-group libraries, (a) nuclide- and energy-group-dependent Bell factor is adopted, (b) multiple R-parameter to consider resonance interference with other nuclides is adopted and (c) Bell factor is adjusted to cancel out errors caused by coarse group structure.
