The assessment of the fission yield uncertainty on neutronic parameters is of great interest for criticality and spent fuel behavior studies. In this work, several fission yield perturbation methodologies are used to propagate the uncertainty on a PWR fuel assembly. The resulting k-inf uncertainty versus the exposure and the nuclide density uncertainties at 60 GWd/MT are assessed and discussed.
