Vanadium alloys exhibit important advantages as a candidate structural material for fusion first wall/blanket applications. These advantages include fabricability, favorable safety and environmental features, high temperature and high wall load capability, and long lifetime under irradiation. Major concerns regarding the use of vanadium alloys for fusion applications relate to cost, reactivity with air/oxygen, and the limited data base. Vanadium alloys with (3--5)% chromium and (3--5)% titanium appear to offer the best combination of properties for first wall/blanket applications. A V-4Cr-4Ti alloy is currently considered as the leading candidate composition.
