Abstract
The present work is aimed to quantify uncertainty propagation through one coupling set between COBAYA 4 and COBRA-TF in thermal-hydraulics and neutronics parameters such as XS-libraries or TH boundary conditions. The main goal of the work is characterizing XS-libraries influence on TH uncertainty propagation by studying TH sensitivity coefficients with and without uncertain XS values, assessing differences in the key design parameters such as PCT, DNBR or k-eff value when XS uncertainty is computed or not and quantifying variance contribution of each uncertain parameter to each objective function by performing calculation at PWR fuel assembly level stationary state.
