Swelling of vanadium alloys was determined after irradiation at 420 and 600{degree}C to neutron fluences ranging from 0.3 {times} 10{sup 27} neutrons/m{sup 2} (17 dpa) to 1.9 {times} 10{sup 27} neutrons/m{sup 2} (114 dpa). Binary and ternary vanadium alloys with Cr, Ti, Mo, W, Ni, Fe, Zr, and Si additions were irradiated in either the fully annealed, partially annealed, or 10% cold-worked condition. The addition of Cr to vanadium greatly exacerbated swelling of vanadium upon irradiation at 600{degree}C, whereas the presence of Ti, Mo, W, and Ni (3--20%) did not significantly affect swelling of vanadium. The swelling of V-Cr alloys upon irradiation at 600{degree}C was substantially reduced (<0.1%/dpa) by the addition of Ti (1--15%). The swelling of the vanadium alloys was <0.2%/dpa upon irradiation at 420{degree}C. Partial annealing or 10% cold-working had an insignificant effect on swelling of the alloys. 5 refs., 5 figs., 1 tab.
