Abstract
The prediction of fission products and the impact of their uncertainties to different safety-related spent fuel applications (burn-up credit, decay heat generation, radio-logical safety, waste management, burn-up prediction) are required for the evalua-tion of spent fuel system designs and safety analysis options. One of the nuclear data needs to this prediction is the independent fission yields. The mostly used general-purpose evaluated nuclear data libraries provide these data including their uncertainties as standard deviation, with no-correlation between fission yields. However, new developments in the theory and measurements of fission product yields are expected to result in new evaluated files in the next coming years. These files will include considerably more accurate yields including neutron ener-gy dependence combined with new covariance information allowing realistic un-certainty estimates.
