AbstractAbstract
[en] In the criticality code validation of common systems, many paths may exist to a correct bias, bias uncertainty, and upper subcritical limit. The challenge for the criticality analyst is to select an efficient, defensible, and safe methodology to consistently obtain the correct values. One method of testing criticality code validation techniques is to use a sample system with a known bias as a test application and determine whether the methods employed can reproduce the known bias. In this paper, a low-enriched uranium (LEU) lattice critical experiment with a known bias is used as the test application, and numerous other LEU experiments are used as the benchmarks for the criticality code validation exercises using traditional and advanced parametric techniques. The parameters explored are enrichment, energy of average lethargy causing fission (EALF), and the TSUNAMI integral index ck with experiments with varying degrees of similarity. This paper is an extension of a previously published summary
