The paper presents results of the development of SMKU code that ports the major part of a code calculating the critical parameters of SMK code system to graphical arithmetic accelerators. Benchmarks typical for a given problem class and our first numerical experiments with the developed code on hybridarchitecture computers are presented. The results obtained using arithmetic accelerators NVIDIA demonstrate, for example, sim 16 times gain in speed in simulations for a set of fuel assemblies in comparison with simulations on a onecore generalpurpose Intel processor with Nehalem architecture and sim 13 times gain in speed in Kfactor simulations for the WWER1000 reactor core. Keywords: arithmetic accelerator, graphic processor, specialpurpose desktop supercomputer, WWER1000, fuel element, fuel assembly.
