Sažetak
In this paper DRAGON 4, FA2D and NEWT transport codes are used for calculation of NPP Krsko 16×16 fuel assemblies without and with IFBAs, for two U-235 enrichments 4.4% and 4.8%, as found in cycle 24 of the plant. The heterogeneous depletion calculation was performed up to burnup of 60 GWd/tU. The prediction capabilities of the codes are compared for infinite multiplication factor, 2-groups homogenized cross section constants, selected isotope number densities, and for 2D pin power form factors. In addition, in case of DRAGON code, the influence of different used neutron data libraries (WLUP based 69-groups libraries were used) was studied.
