CSRL-V ENDF/B-V Library and Thermal Reactor and Criticality Safety Benchmarks
- Oak Ridge National Laboratory (ORNL), Oak Ridge, TN (United States)
CSRL-V, an ENDF/B-V 227-group neutron cross-section library which has recently been expanded to include Bondarenko factor data for unresolved resonance processing, was used to calculate performance parameters for a series of thermal reactor and criticality safety benchmarks. Among the thermal benchmarks calculated were the Babcock and Wilcox lattice critical experiments B and W-XIII and B and W-XX. These two slightly enriched (2.46%) UO2, water-moderated, tight-pitch lattice experiments were chosen because (a) they have similar U238 resonance shielding characteristics as power reactor cores, and (b) they provide benchmark results representative of high-leakage and low-leakage lattices, respectively. Among the criticality safety benchmarks calculated were homogeneous, highly enriched (93.2%) uranyl fluoride spheres with hydrogen-to-uranium ratios varying from 76 to 972.
