Times Cited Count：2 Percentile：18.29(Materials Science, Multidisciplinary)Nuclear data are indispensable for development of fusion reactor candidate materials. However, benchmarking of the nuclear data in MeV energy region is not sufficient even now. In the present study, benchmark performance in the MeV energy region was investigated theoretically in case of experiments by using a 14MeV neutron source. We carried out a systematical analysis for light to heavy materials. As a result, the benchmark performance for neutron spectrum was confirmed to be acceptable, while for 
-ray it was not sufficient. This indicates it was effective to use a spectrum shifter. As a shifter beryllium had the best performance. Moreover, it was preliminarily examined whether it is really acceptable that only the spectrum before last collision is considered in the benchmark performance analysis. It was pointed out that not only the last collision but also more previous collisions should be taken into account equally in the benchmark performance analysis.

4.1 with TOF experiments at OKTAVIANIsobe, Yuta*; Yoshida, Shigeo*; Konno, Chikara
no journal, ,
A benchmark test of ENDF/B-VIII4.1 being developed in US were carried out with Co and Cu experiments in the OKTAVIAN TOF experiments. For the comparison, ENDF/B-VII.1 and JENDL-4.0 were also used. As a result, it is found out that the analysis results with ENDF/B-VIII4.1 agreed the measured data better than those with the other nuclear data in the Co experiment, while they are in worse agreement with the measured data than those with the other nuclear data in the Cu experiment. It is also demonstrated that the differences between the analysis results with ENDF/B-VIII4.1 and ENDF/B-VII.1 come from the inelastic scattering data to continuum states in 
Co and all the inelastic scattering data in 
Cu and 
Cu.
