摘要
针对聚变堆特定的辐照条件,对离子辐照、裂变中子辐照、散裂中子辐照以及聚变辐照装置进行了比较,评述了不同装置的优势和缺点。在没有可用的14MeV中子源时,离子加速器、裂变堆、散裂中子源以及理论模拟在聚变材料辐照效应的研究中具有不可替代的作用。从离子辐照、裂变中子或散裂中子辐照获得的数据与真实聚变中子辐照结果的对应关系需要通过采用14MeV高通量中子辐照(如IFMIF)来证实。功能强大、经济性好的聚变材料辐照装置的建立及多尺度数值模拟的发展是聚变材料走向聚变堆应用的必由之路。
On the basis of specific irradiation conditions in fusion reactor,the advantages and limitations of the main proposed irradiation facilities including ion irradiation,fission neutron irradiation,spallation neutron irradiation and fusion neutron irradiation were compared and evaluated.Ion accelerators,fission reactors and theory and modeling are expected to continue to play an indispensable role in studying the irradiation effect of fusion materials before the 14 MeV neutron source is available.The corresponding relation between irradiation data from real fusion neutron and irradiation data from ion,fission neutron or spallation neutron irradiation has to be verified by irradiation using 14 MeV high flux neutron source（e.g.IFMIF）.The construction of powerful,economy-efficient fusion materials irradiation facility and the development of multi-scale numerical simulation are the inevitable choices to facilitate the commercialized application of fusion materials.
