Proposal for the utilization of the total cross section covariances and its correlations with channel reactions for sensitivity and uncertainty analysis
Abstract
An alternate method for the estimation of the global uncertainty on criticality, using the total cross section and its covariances, is proposed. Application of the method with currently available covariance data leads to an unrealistically large prediction of the global uncertainty on criticality. New covariances for total cross section and individual reactions are proposed. Analysis with the proposed covariance matrices is found to result in a …
