Sažetak
Using Scale-4 code package and MCNP4A Monte Carlo code we have analysed burnup related reactivity credit for the NPP Krško spent fuel pool. We have found that the assumption of fission product absorption exclusion in criticality calculations can give a good but still conservative estimate for the burnup related reactivity credit for the spent fuel pool. For the 4.3 w/o enriched fuel, burned to 40 GWd/tU and cooled down for two years, reactivity credit of 0.15 keff was obtained. Based on this assumption a preliminary calculations suggest that an increase in storage capacity of approximately 50% is possible, if the total operational space of spent fuel pool is to be used.
