Sažetak
FA2D is 2D transport collision probability code developed at Faculty of Electrical Engineering and Computing, University Zagreb. It is used for calculation of cross section data at fuel assembly level. Usual application of obtained cross section data, including pin power reconstruction data, is within NRC’ s PARCS code for 3D core calculation. This paper presents results of calculations performed for NPP Krsko 16x16 standard fuel and NGF fuel with different number of IFBA rods and for different Gd2O3 content. Two codes are used in calculation: FA2D and SCALE5 TRITON calculation sequence (based on discrete ordinates code NEWT). The results obtained with FA2D spectral code for reflected heterogeneous 2D fuel assembly geometry are presented for burn-up dependency of infinite multiplication factor, 2D pin power distributions, and for local peaking factor.
