A fusion neutronics benchmark experiment on vanadium-alloy was conducted. Various nuclear quantities related to both neutrons and gamma-rays were measured. It was found through benchmark analyses that all the cross section data of mainly vanadium in recent nuclear data files still involved serious problems. Improvement of these data is strongly required. According to discussion on neutron KERMA factors, the major finding was that neutron KERMA factors based on ENDF/B-VI above 10 MeV were too large due to the larger ⁵¹V(n,n'p)⁵⁰Ti cross section.
