Abstract

Sensitivity analysis is an important tool in the study of nuclear systems. In our recent work, we introduced a hybrid method that combines sampling techniques with first-order sensitivity analysis to approximate the effects of uncertainty in parameters of a nuclear reactor simulation model. For elementary examples, the approach offers a substantial advantage (in precision, computational efficiency, or both) over classical methods of uncertainty quantification [1].
