Equilibrium Cycles of NPP Krško after Power Uprate

The existing steam generators of Krško Nuclear Power Plant will be replaced in the recent future and at the same time the reactor core power will be increased from current 1876 MW(th) to 1994 MW(th). This core power uprating will surely impact the nuclear core design. The equilibrium cycle core model for uprated NPP Krško conditions using the computer code package FUMACS has been developed. 18 months equilibrium cycles for single and split feed enrichment batches of 48 and 52 fresh fuel assemblies were generated in that model. The analysis of these preliminary loading patterns of 18 months equilibrium cycles showed that it is possible to design the reactor core for 18 months cycle, which meets the safety limits for uprated conditions.
