A set of 23 additional critical experiments were analyzed to provide additional input to the criticality validation portion of spent fuel cask analysis. The results of this analyses were combined with the previously analyzed criticals to determine the upper safety limit on keff. The combined set of criticals can be used for criticality validation for burnup credit and are better suited for the range of isotopics in spent nuclear fuels. A trend observed in the analysis was that the calculated keff deviates from the criticals in the positive direction, implying that increased burnup results in increased safety margin.
