在加速器驱动系统(ADS)的设计与运行过程中的放射性废物循环处置、氚的产生、散裂中子源的设计、医用中子和质子治癌等方面,均对20MeV以上能区截面数据提出要求。在诸如反应堆特别是快中子增殖反应堆包壳层材料、准直器材料、反应堆设计中结构材料的选取以及在辐射防护研究中人体组织中所包含的各种核素在20MeV以上能区各反应数据均很重要。另外,相关核素20MeV以上能区反应数据在输运程序中对中子的产生、中子的影响、能量沉积、剂量模拟、屏蔽体设计及材料活化等方面的模拟计算均起至关重要作用。核数据评价工作整体发展趋势上,国际各
In the design and operation of accelerator drive system (ADS), recycling of radioactive waste, production of tritium, spallation neutron source design, medical neutron and proton cancer, etc., are presented above 20MeV energy region data Claim. In such as reactors, especially fast breeder reactor cladding materials, collimator materials, the choice of structural materials in reactor design and radiation protection research in the human body contains a variety of radionuclides in more than 20MeV energy region of the reaction The data is important. In addition, the correlation data of energies above 20 MeV in the radionuclide nuclei plays a crucial role in the simulation of the production of neutrons, neutron, energy deposition, dose simulation, shield design and material activation in the transport program . The overall development trend of nuclear data evaluation work, the international community
