介绍了10MW高温气冷实验堆（HTR-10）与氦冷却剂相关的工艺系统各设备中的辐射源，并以QAD-CG程序完成了各设备间的辐射屏蔽计算。计算结果表明，工艺系统各设备中的辐射源强较低，即使对这些设备不进行附加屏蔽，其大多数设备外表面处的辐射剂量率仍满足限定工作区剂量率管理限值要求，并且对这些设备所在的房间进行整体屏蔽的要求不高（10～20cm厚的温凝土即可）。因此，建筑物结构设计厚度就能满足要求。
The radiation sources in each equipment of HTR-10 and helium coolant related process system are introduced. And the radiation shielding calculation between each equipment is completed by QAD-CG program. The calculated results show that the radiation source intensity in the equipment of the process system is relatively low, and even if these devices are not additionally shielded, the radiation dose rate at the outer surface of most of the devices still meets the management dose rate limit requirement in the work area, The room in which these devices are located is less demanding overall shielding (10-20 cm thick concrete). Therefore, the thickness of the building structure design can meet the requirements.
