Sensitivity Analysis of the Gap Heat Transfer Model in BISON

Swiler, Laura P.; Schmidt, Rodney C.; Williamson, Richard W.; Perez, Danielle P.

This report summarizes the result of a NEAMS project focused on sensitivity analysis of the heat transfer model in the gap between the fuel rod and the cladding used in the BISON fuel performance code of Idaho National Laboratory. Using the gap heat transfer models in BISON, the sensitivity of the modeling parameters and the associated responses is investigated. The study results in a quantitative assessment of the role of various parameters in the analysis of gap heat transfer in nuclear fuel.
