Impact of nuclear data uncertainty on time-average models of CANDU-9

Uncertainty analysis has been performed on a time-average CANDU-9 model using the codes PARCS, SCALE and Serpent. An acceptable target exit burnup scheme was generated based on reference nuclear data, with maximum channel and bundle powers of 6.47 MW and 849 kW, respectively. Uncertainty analysis of the time-average model was then performed using 150 perturbed nuclear data sets. The largest relative standard deviation in channel power was found …
