Strategy of fusion reactor materials R&D in China

There are two phases of fusion reactor materials R&D in China. The first phase will focus on fusion materials R&D for fusion breeders (or breeders for short) and in the second phase fusion materials for commercial pure fusion reactors will be developed. China is now in the first phase. Now development of reduced activation oxide dispersion strengthened ferritic steels, low- and high-Z plasma facing materials, including carbon base materials, Be, advanced W-alloys and functionally graded material, will be emphasized. Limited research activities for the second phase, e.g. V-Cr-Ti alloys and SiC/SiC composite development, are also supported. Fusion reactor materials R&D status in China is introduced and some research results are also given in present paper. (C) 2002 Published by Elsevier Science B.V.
