A nuclear data library is one of the most important data which control the calculation accuracy in nuclear analyses for fusion reactor designs. IAEA compiles the best data from the evaluated nuclear data libraries in the world each nuclei for fusion reactor applications. This library is Fusion Evaluated Nuclear Data Library (FENDL). In 2008 IAEA started a new coordinate research project to update the current version FENDL-2.1, to extend the neutron energy range from 20 MeV more than 60 MeV for 180 nuclei. This new version FENDL-3.0 was released in 2012. We have benchmarked FENDL-3.0 with integral experiments at FNS in JAEA and TOF experiments at OKTAVIAN in Osaka University in Japan. The Monte Carlo code MCNP-5 and the ACE file of FENDL-3.0 supplied from IAEA were used for the benchmark test. We also carried out calculations with the current version FENDL-2.1 and the latest JENDL-4.0 for comparison. As a result, it is demonstrated that the FENDL-3 is as accurate as FENDL-2.1 or more.
