Validation of KENO VI: a comparison with hexagonal lattice LWR critical experiments
- Oak Ridge National Lab., TN (United States)
The KENO VI Monte Carlo code, released with Version 4.3 of the SCALE code system, provides the capability to model more complex geometries than previously allowed by KENO V.a. One significant improvement is the simplistic specification of hex-prism unit cells and hexagonal arrays, an arduous task to complete in KENO V.a. This report documents the validation of KENO VI against 30 critical experiments consisting of low-enriched uranium, light water reactor (LWR) fuel rods in hexagonal lattices with no poisons. The reference, enrichment, pitch, cladding, and core identification of the experiments are given. The results indicate that KENO VI accurately calculates these critical experiments, with a bias of {minus}0.51% for the 238-group cross-section library and {minus}0.24% for the 44-group cross-section library. If these biases are properly taken into account, the KENO VI code can be used with confidence for the design and safety analysis of storage and transportation systems of similar LWR-type fuels.
