| 摘 要： | 中子残余应力谱仪静态屏蔽体主要用于对谱仪装置的附加闸门、中子导管等组件的辐射剂量的屏蔽,使装置操作人员可以安全地在装置周围活动。通过MCNP5程序对谱仪装置静态屏蔽体的屏蔽能力进行了计算,可为该方案的改进、优化提供依据,以便最终制造出满足辐射剂量要求的屏蔽体。

| Abstract: | The static shielding of Residual Stress Neutron Diffractometer(RSND) is mainly used to protect the workers against-rays and neutrons from the reactor.The static shielding is mainly around the additional shutter and the neutron guide system.For providing ensured safety for personnel in the experiments area,calculations of the shielding system were carried out using the MCNP5 code.The shielding design can be optimized based on the calculation results. |
