Effect of Fission Spectrum Data Uncertainty on Criticality Benchmark Calculations by McCARD

摘要

At the recent international nuclear data conference ND2010, held last April in Jeju Island, Korea, a question is raised with regard to the effect of the fission spectrum data uncertainty on criticality calculations. This paper is designed to examine the problem using the fission spectrum covariance data available in evaluated nuclear data libraries and a Monte Carlo (MC) uncertainty analysis method implemented in McCARD code [1].
