[O39] Sensitivity and Uncertainty Analysis of Neuronics Parameters in PWR Cells Using Improved Method
Keywords:Sensitivity, Uncertainty, Self-shielding, PWR cells
We have developed a new method for calculating sensitivity coefficients taking in to account the effect of self-shielding factor. we have calculated sensitivities and uncertainties in UO2 and MOX fueled PWR cells. In sensitivity calculations, we have verified our method by comparing with MCNP code. For uncertainty analysis, we have compared with reference which used CASMO-4.
