为了考察共振自屏效应对混合堆包层中子学设计的影响,使用了NJOY程序,由ENDF/B-4库数据制作了13个核素,42群中子,21群光子耦合参数。研制了与具体模型几何结构材料组成相关的自屏处理程序。用ANISN程序对快裂变包层与抑制裂变包层的群截面自屏效应做了对比计算和分析。
In order to investigate the effect of resonance self-shielding effect on the neutron design of hybrid stack, NJOY program was used and 13 nuclides, 42 neutron and 21 photon coupling parameters were generated from ENDF / B-4 library data. Developed a self-screen processing program related to the material composition of the specific model geometry. ANISN program was used to calculate and analyze the self-screen effect of group cross-section of fast fission cladding and fission suppression cladding.
