论文简介    Abstract To optimize the shield for neutrons and gamma rays compact and lightweight, a method combining the structure and components together was established employing genetic algorithms and MCNP code. As a typical case, the fission energy spectrum of 235 U which mixed neutrons and gamma rays was adopted in this study. Six types of materials were presented and optimized by the method. Spherical geometry was adopted in the optimization after checking the geometry effect. Simulations have made to verify the reliability of the optimization method and the efficiency of the optimized materials. To compare the materials visually and conveniently, the volume and weight needed to build a shield are employed. The results showed that, the composite multilayer material has the best performance. 关键词 Compact , Gamma , Lightweight , Neutron , Optimization , Shield 作者机构 [Cai Yao]Xi'an Jiaotong University,Xi'an,China [Hu Huasi]Xi'an Jiaotong University,Xi'an,China.CA: huasi_hu@mail.xjtu.edu.cn [Pan Ziheng]Xi'an Jiaotong University,Xi'an,China [Hu Guang]Xi'an Jiaotong University,Xi'an,China [Zhang Tao]Xi'an Jiaotong University,Xi'an,China DOI: 10.1016/j.apradiso.2018.05.009
