Keywords:Uncertainty quantification, Sensitivity, Control variate method

We have proposed an effiient random sampling method with sensitivity profiles and the control variate method. With this method, it becomes possible to estimate statistical quantities such as mean values and standard deviations with less number of samples than with the normal random sampling method. In this presentation, some numerical examples about uncertainty quantification of nuclide number densities after fuel depletion will be presented.
