Sažetak
A preliminary analysis of the concrete cask for the intermediate dry storage of the spent fuel of NPP Krško should include an estimation of the effective multiplication factor Assuming 16x16 fuel elements, 4.3% initial enrichment, 45 GWd/tU burnup and 10 years cooling time, a concrete spent fuel cask capacity of10 spent fuel assemblies is proposed. Fuel assemblies are placed inside inner catty in a "basket" - a boron (1%) doped steel structure Heavy concrete (25% Fe), 45 cm thick, is enclosed in a carbon steel shell. There is also a stainless steel (SS304) lining of the storage cavity Isotope inventory of the spent fuel after a 10 years cooling time is calculated using OFIIGEN-S functional module of the SCALE-4.2 code package The effective multiplication factor k_eff of dry (helium filled) and wet (water filled) cask for fresh and used fuel is calculated using CSAS4 Monte Carlo method based control module of the same SCALE-4.2 code package. The obtained results of k_eff of the dry cask for fresh and spent fuel are well below the required 0 95 value, but those for the water filled cask are above this value. Therefore, several additional calculations of the k_eff varying the thickness of a boral basket structure which had replaced the stainless steel one were done It tumed out that at least a 1.5 cm thick boral wall was needed to meet the required 0.95 value for k_eff.
