The discrepancies between the calculated and experimental results were found in some experiments of the previous study, where the measured data might include background neutrons scattered in the concrete wall of the experimental room. Thus we perform new integral experiments with few background neutrons and validate nuclear data adequately in this study. It is found out that the nuclear data on tungsten and vanadium have no problems, while there are still concerns in the nuclear data on copper, molybdenum and titanium. We describe the details of the nuclear data on copper, molybdenum and titanium based on the experimental results in this study, and propose the modification of the nuclear data., 26th IAEA Fusion Energy Conference}, title = {New integral experiments for a variety of fusion reactor materials with DT neutron source at JAEA/FNS}, year = {2016} }
