锆合金研究进展及我国核电站用锆材国产化的思考

摘要

The recent research progresses of zircaloy used in nuclear power plants in home and abroad, including France M5 alloy, U. S. Zirlo alloy, Russian E635 alloy, Japan' s NDA alloy, and South Korea' s HANA alloys, were comprehensively reviewed. The problems happened during the research on zircaloy materials for nuclear power plants and the difficulties of zircaloy materials localization were analyzed, and strategy and suggestion for R&D of new zircaloy material in China were proposed.%综合评述了国内外核电站用锆合金材料的研究进展,重点介绍了目前国际上发展成熟的高性能锆合金:法国的M5合金、美国的Zirlo合金、俄罗斯的E635合金、日本的NDA合金及韩国的HANA合金.分析了我国在核电站用锆合金材料研制过程中存在的问题,以及我国核电用锆材国产化的难点.对我国核电用锆材的发展思路提出了几点建议.
