“…4, the calculation by JENDL-FF best predicts th'e experimental ')'-ray spectrum. The spectrum by ENDF-6 is lower, especially in the prominent peak at rvl.6MeV observed in the experiment, while that by EFF-3 is higher as a whole compared with the measured Total cross sections of vanadium in the energy range between 0.1 and lOkeV in JENDL-FF, ENDF/ B-VI and EFF-3 compared with the experimental data (30)(32) (33) spectrum.

A neutronics benchmark experiment on vanadium, which is a low activation fusion reactor material, was conducted by using the D-T neutron source facility ofFNS/JAERI. Neutron spectra, dosimetry reaction rates, ,-ray spectra and ,-ray heating rates were measured in a vanadium experimental assembly. Benchmark tests for four evaluated nuclear data files were performed by analyzing the experiment. As a result, the following problems were pointed out in view of accuracy of fusion reactor designs. (1) JENDL-FF and JENDL-3.2: Total cross section should be reexamined especially at "'2keV. (2) ENDF/B-VI: Double differential cross sections for 14 Me V neutrons should be revised because of the isotropic angular distribution for continuum neutron emission. Gamma-ray production cross sections are too small and discrete ,-ray peaks are not represented clearly. (3) EFF-3: Gamma-ray production cross sections are too large.
