We performed a benchmark experiment with a titanium assembly and a DT neutron source at JAEA/FNS. The assembly was a titanium slab of 45 cm 45 cm 40 cm covered with 5 or 10 cm thick LiO blocks. Dosimetry reaction rates were measured by the foil activation method of niobium, indium and gold inside the assembly. And fission rate of U was measured by using micro fission chambers. This experiment was analyzed by using Monte Carlo neutron transport code MCNP5 with recent nuclear data libraries of ENDF/B-VII.1, JEFF-3.1.2, JENDL-4.0, etc. The calculation results were compared with the measured one in order to validate nuclear data libraries of titanium.
