Integral experiment testing was carried out for neutron leakage spectra experiment from 40-cm tungsten pile and criticality experiment with tungsten reflector using the continuous-energy Monte Carlo code MCNP and the different natural tungsten data generated from CENDL-3.1, FENDL-2.0, ENDF/B-VII and JENDL-3.2. From the benchmark test results, we can say that neutron leakage spectrum obtained with CENDL-3.1 shows good agreement with experimental measurement below 5 MeV, but the leakage spectra at 5 ~ 13 MeV were underestimated with CENDL-3.1, JENDL-3.2 and ENDF/B-VII, especially the CENDL-3.1, but FENDL-2.0 gives better result in this energy range. For criticality experiment, CENDL-3.1 underestimates criticality by 514 pcm. Further improvement need to be made for tungsten in CENDL-3.1.
