Towards the development of upper subcriticality limits on the basis of benchmark criticality calculations

Nevertheless, we presume that similar deficiencies in the specification of the configurations belonging to one or similar series of experiments could cause unspecified experiment/evaluation-related systematic errors in the benchmark evaluations and consequently in the keffbench-values. Therefore, even distribution-free estimates will not be rigorous because they also rely on the assumption of random sampling of the keffcalc/keffbench population. Moreover, we suggest that the question of normality appears to be of minor importance compared to other hypotheses and to the conservative approximations typically assumed for criticality safety evaluations.
