摘要(Abstract)：

点核积分方法是辐射剂量计算的基本方法之一,广泛应用于辐射防护领域。传统的点核剂量计算中采用文本方式描述计算模型,存在难以描述复杂几何、易出错且耗时的问题。针对该问题,本文基于FDS团队自主研发的超级蒙卡核模拟软件系统SuperMC,进行了基于CAD的点核剂量计算方法研究与程序开发,可基于实际问题的CAD模型直接进行支持多重源的光子点核剂量计算,提高了程序对复杂三维几何问题的处理能力,并包含较为完备的核数据库。使用ANSI/ANS6.6.1、ESIS和VisiPlan的基准例题对程序进行了测试验证,测试结果与VisiPlan4.0对比吻合良好。同时将该方法初步应用于ITER热室屏蔽的设计中,说明了本方法及程序处理复杂场景问题的能力。
