在国际聚变材料辐照装置(IFMIF)中子源高通量测试模块(HFTM)和采用氦冷却锂铅(HCLL)和球床(HCPB)包层的典型聚变功率反应堆(FPR)第一壁上进行了辐照模拟，分析了低活性钢Eurofer的形变行为。利用分析和拉普拉斯自适应放射性分析(ALARA)程序和IEAF-2001数据对IFMIF和EASY-2003聚变堆(FPR)辐照系统进行了形变计算。分析表明，欧洲铁和铬等主要成分的变性不明显。次要成分，如钛、钒和锰，在第一核电站中每年增加5-15%，在IFMIF HFTM中增加10-35%。其他次成分如B、Ta和W表现出不同的相变行为，导致在IFMIF和聚变动力反应堆中进行高通量照射后，Eurofer钢的元素组成不同。(C)2004爱思唯尔B.V.保留所有权利。
The transmutation behaviour of the low activation steel Eurofer was analysed for irradiation simulations in the high flux test module (HFTM) of the International Fusion Material Irradiation Facility (IFMIF) neutron source and the first wall of a typical fusion power reactor (FPR) employing helium cooled lithium lead (HCLL) and pebble bed (HCPB) blankets. The transmutation calculations were conducted with the analytical and laplacian adaptive radioactivity analysis (ALARA) code and IEAF-2001 data for the IFMIF and the EASY-2003 system for the fusion power reactor (FPR) irradiations. The analyses showed that the transmutation of the main constituents of Eurofer, including iron and chromium, is not significant. Minor constituents such as Ti, V and Mn increase by 5-15% per irradiation year in the FPR and by 10-35% in the IFMIF HFTM. Other minor constituents such as B, Ta, and W show a different transmutation behaviour resulting in different elemental compositions of the Eurofer steel after high fluence irradiations in IFMIF and fusion power reactors.
