This paper is devoted to a comparison of the experimental and calculated leakage neutron spectra and total neutron leakages from U, Th, Pb and Be spherical assemblies and also to a comparison of experimental and calculated reaction rates in U and Th assemblies.It was shown that the calculation with ENDF/B-IV data describes the shape of the neutron spectrum better for all considered materials. The full multiplication of neutrons for the U assembly is reproduced more accurately by the calculation with ENDL-75 data, and for Th, Be and Pb assemblies, by the calculation with ENDF/B-IV data.
