The Transmutation by Adiabatic Resonance Crossing (TARC) experiment was performed in order to demonstrate the efficiency of the neutron Adiabatic Resonance Crossing (ARC) moderation effect in the transmutation of long lived fission products (as Tc and I) in a large Lead Block. The high quality of data makes TARC experiment a good benchmark for validation of neutron physics over a broad energy. This article describes the result of the validation for the PHITS code and JENDL/HE file by the TARC experiment. The analysis revealed the neutron flux by the PHITS code is 1.15 times larger than that by the MCNPX code, while both flux are within the experimental error. Flux using JENDL/HE file agreed better to the experimental result than that using the LA-150 nuclear library.
