In present study the benchmarking of TARC experiment was done. MCNPX code with JENDL-HE, JENDL-4, JENDL-3.3 and LA-150 nuclear data libraries were used for simulations. The calculated neutron fluences, energy-time correlations of resonance reactions and transmutation rates of 99Tc and 127,129I were compared with experimental measurements. On the base of comparative analysis of simulations the validation of nuclear data libraries was performed and recommendations were given, as follows:the JENDL-4 library contains better neutron elastic cross-section data for natural lead in energy range from ∼0.01 eV to ∼100 eV comparing to other considered data libraries;the JENDL-HE (JENDL-3.3) has better neutron inelastic scattering cross-sections for lead in energy range of 1-3 MeV, although the experimental errors in neutron fluence are rather large;neutron capture cross-sections of 129I in JENDL-4 library should be used for 129I transmutation process simulations.
