基于DELMIA软件二次开发了堆舱辐射场可视化和人体受照辐射剂量模拟计算的功能.通过辐射场可视化将反应堆堆舱内辐射强弱区域分布情况直观地展示出来,从而辅助检修人员工作,减少人员所受辐射剂量,提高其工作效率.通过人体模型受照辐射剂量模拟计算可以了解人体所受到的损伤程度,从而为检修人员提供必要的辐射防护措施.通过对输出的统计报表进行分析,可以对检修工艺进行评价和优化,对实际的反应堆检修工程有指导意义.计算结果实时快速,显示效果良好.“,”The function of the visualization of radiation field in the reactor cabin and simulation calculation of human body absorbed radiation dose is developed based on the DELMIA soRware.The reactor cabin radiation intensity distribution is displayed visually by radiation field visualization,which can assist the work of personnel maintenance,reduce the radiation dose of the staff,and improve the work efficiency.Through the simulation calculation of the human body absorbed radiation dose,the human body damage degree can be understood,so as to provide the necessary radiation protection measures for the maintenance staff.Based on the analysis of statistical reports output,the maintenance process can be evaluated and optimized,and this plays an important role in the actual reactor maintenance engineering.The calculation result is fast and real-time,and the display effect is good.
