Abstract

Vanadium, as a candidate for the blanket material in fusion reactors, was being considered by the engineering design activities (EDA) of the international thermonuclear experimental reactor (ITER) project. A thorough study of the total neutron cross section was therefore initiated at the 1 ns pulsed Geel linear accelerator (GELINA) with measurements on 99.8% pure natural vanadium. Time of flight neutron transmission measurements were performed on three samples, 2 mm, 14 mm and 28 mm, to cover the neutron energy range from 80 eV up to 20 MeV. The thinnest sample measurement was done at 50 m neutron flight length and the other samples at 400 m. Below 100 keV resonance parameter analysis has been carried out with R-matrix codes. Above 250 keV the very high resolution 400 m data have been reduced to total cross section and compared with the most recent evaluations.
