摘　　要：反应堆生物屏蔽层的拆除是反应堆退役阶段的重要任务之一,生物屏蔽层辐射场的数字化可为反应堆退役中的辐射防护和废物管理提供重要信息。本文通过构建三维辐射场计算模型,采用粒子输运计算程序(MCNP)获得了SPRR-300反应堆生物屏蔽层三维辐射剂量场;运用3Dmax、Pro/E等建模工具建立了生物屏蔽层剂量场三维仿真场景和模型,直观地展示了生物屏蔽层活度状况和剂量分布,实现放射性水平分布可视化。Reactor biological shielding layer is one of the important source items in the reactor decommissioning stage.The digitization of radiation field of biological shielding layer can provide important information for radiation protection and waste management in reactor decommissioning.In this paper,by constructing a threedimensional radiation field calculation model,the three-site radiation dose field of the SPRR-300 reactor biological shielding layer was obtained by using the particle transport calculation program(MCNP).The three-dimensional simulation scene and model of the biological shielding layer dose field were established by using 3Dmax,Pro/E and other modeling tools.The activity and dose distribution of the biological shielding layer were visually displayed,and the visualization of the horizontal distribution of radioactivity was realized.
