Integral benchmark experiments with 14-MeV neutrons for testing the nuclear data of vanadium

The measurements of the gamma-ray and neutron leakage spectra from three vanadium spheres with diameters 10, 24 and 34 cm irradiated by a central 14-MeV neutron source were carried out in the frame of the ISTC Project #910 in collaboration with Forschungszentrum Karlsruhe. The neutron leakage spectra were measured by scintillation detectors and by a gas proportional counter. The gamma-ray leakage spectra were measured with the help of a crystal NaI(Tl). Analysis of these experiments was performed with the available and newly evaluated nuclear data files prepared in the frame of the project activities. A comparison of experimental and calculated neutron and gamma-ray leakage spectra from three vanadium spheres is given.
