中国核能安全技术研究所（INEST）正在中国范围内广泛合作下开发中国低活化马氏体（CLAM）钢。对CLAM钢进行了大量的研发工作，以帮助其适用于工业应用。研究了精炼工艺和热时效对合金成分、显微组织和力学性能的影响。对辐照前材料的冲击、断裂韧性、热老化、蠕变和疲劳性能等进行了评价。在成都高通量工程试验堆（HFETR）和德国保罗谢勒研究所（PaulScherrer Institute）的空间中子源（SINQ）上进行了20 dpa的一系列辐照试验。在DRAGON-I和PICOLO回路中进行了超过10，000小时的PbLi腐蚀试验。正在开发试验包层模块（TBM）的制造技术，并正在用CLAM钢制造1/3比例的TBM原型。介绍了近年来该钢的发展状况。CLAM钢的规范鉴定正在计划中，以便将来在ITER-TBM和DEMO中最终应用。(C)2014爱思唯尔有限公司版权所有。
The China low activation martensitic (CLAM) steel is being developed at the Institute of Nuclear Energy Safety Technology (INEST) under wide collaboration within China. Significant R&D work on CLAM steel was carried out to help make it suitable for industrial applications. The effect of refining processes and thermal aging on composition, microstructures and mechanical properties were investigated. Material properties before irradiation including impact, fracture toughness, thermal aging, creep and fatigue properties etc. were assessed. A series of irradiation tests in the fission reactor HFETR in Chengdu up to 2 dpa and in the spallation neutron source SINQ in Paul Scherrer Institute up to 20 dpa were performed. PbLi corrosion tests for more than 10,000 h were done in the DRAGON-I and PICOLO loops. Fabrication techniques for a test blanket module (TBM) are being developed and a 1/3 scale TBM prototype is being fabricated with CLAM steel. Recent progresses on the development status of this steel are presented here. The code qualification of CLAM steel is under plan for its final application in ITER-TBM and DEMO in the future.
