Uncertainty Propagation of Fission Product Yield Data in Spent Fuel Inventory Calculations

Abstract

The effects of correlations between uncertainties of independent yields are considered to propose a method of including covariance terms within uncertainty propagation for spent fuel inventory calculations and a method outlined to achieve this. The use of the “Total Monte-Carlo” technique for such calculations are investigated for a simple decay example and for the case of a fission pulse calculation and the results discussed.
