The paper presents results of the development of SMK-U 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 hybrid-architecture 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 one-core general-purpose Intel processor with Nehalem architecture and sim 13 times gain in speed in K-factor simulations for the WWER-1000 reactor core. Keywords: arithmetic accelerator, graphic processor, special-purpose desk-top supercomputer, WWER-1000, fuel element, fuel assembly.
