Description

TSUNAMI, a sensitivity and uncertainty analysis tool, was applied to study the intrinsic physics parameters of a (Th,Pu)O2 fuel bundle experiment in ZED-2. This paper focuses on the investigation of moderator purity reactivity (MPR) by modelling the (Th,Pu)O2 experiment in two cases with slightly different moderator purity. TSUNAMI analysis derived reaction-specific sensitivity coefficients since they must be taken into account in the calculation of keff and MPR uncertainties. Isotopes in the (Th,Pu)O2 bundle were found to be the major uncertainty contributors in MPR and they have greater keff sensitivity responses in the less pure ZED-2 model. (author)
