In this paper results of intercomparison of nuclear neutron cross sections for actinides from different evaluated nuclear data libraries such as BROND-2.2(3) (Russia), ENDF/B-VI.8 and ENDF/BVII.
0 (USA), JENDL-3.3 (Japan), JEFF-3.1 (the Western Europe) are presented. It is shown, that the differences existing between nuclear data from BROND-2.2(3), ENDF/B-VI.8, ENDF/BVII. 0, JENDL-3.3, JEFF-3.1 libraries are outside the required accuracies on knowledge of the evaluated neutron data as for fuel elements, and, in a greater measure, for minor actinides. The data of the JEFF-3.1, ENDF/B-VI.8, ENDF/B-VII.0, JENDL-3.3 and BROND-2.2(3) libraries were analyzed for the 232Th 233,235,238U, 237Np, 239,240,242Pu, 241,242m,243Am transactinides. The comparison with the integral fast breeder reactor (BR-5 reactor) experiments was made.
