Spectral Codes Pin Power Prediction Comparison
Spectral codes are able to produce burnup dependent fuel assembly homogenized neutron cross sections and pin power form factors. Both information are used by diffusion nodal codes to produce fuel assembly powers and intra assembly power distributions. 2D transport codes are usually used for this type of the calculation. Four spectral codes (DRAGON 4, FA2D, NEWT and PSG2/Serpent) were used to calculate pin power distribution for reflected single fuel assemblies during depletion. The NPP Krško 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, were modeled. 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, and for 2D pin power form factors.
