Abstract
The application of vanadium alloys as structural materials for the first wall or blanket of a fusion reactor will depend strongly on their compatibility with the coolants and breeding materials included in the blanket system. In the case of the use of liquid alkali metals, lithium offers the advantage of being an excellent heat transfer fluid as well as an excellent breeder of tritium. For the studies of the corrosion behaviour of V 3Ti 1Si in flowing lithium, a pumped lithium loop was designed and constructed. The results gained so far indicate that this vanadium alloy is, from the point of view of compatibility with liquid lithium up to 823 K, a promising material for the application in fusion reactor technology.
