Abstract
Two novel low-activation materials for a fusion reactor first wall and blanket structures are examined: a vanadium- based alloy (V-4Cr-4Ti) and a SiC/SiC composite. The comparison concerns low-activation proper ties, and stresses the importance of data on the impurity content. In particular, new data about impurity levels in vanadium alloys show tha t long-term activation of such materials may be strongly reduced if ce rtain impurities are kept under control.
