ABSTRACT
The upgraded VVR-SM type (Russian design) Budapest Research Reactor using 36% enriched uranium serves both research and practical applications. As a by-product of the experimental methods used in the field of the neutron activation analysis a unique opportunity arose for benchmarking the neutron physical algorithms against measurements. The two dimensional MULTICELL transport code was tested against foil activity measurements and Monte Carlo calculations. The comparison indicated the need of three-dimensional treatment even in case of calculating local spectrum characteristics. The application of the few-group spectrum calculated with the DIF3D diffusion code improved the accuracy of the calculated reaction rate ratios.
