摘　　要：随着核聚变技术水平和全球聚变关注度的不断提升,我国聚变装置数量随之不断增加。聚变装置技术路线多样、类型丰富、组成复杂,聚变装置的不断发展为辐射安全工作带来了新挑战。目前,我国已建成和正在建设的聚变装置多为以氢气为工作介质的磁约束聚变等离子体物理实验装置,这类装置的主要辐射风险来源于装置运行时逃逸电子在事故工况下产生的辐射影响。本文通过产生机理分析、理论估算评估和监测数据分析等方法对磁约束聚变装置的逃逸电子辐射影响进行了研究,并提出了相关辐射防护建议。With the development of fusion technology and global attention,the number of fusion devices in China has increased significantly.The diversified technical approaches,heterogeneous configurations,and inherent complexity of fusion devices pose new challenges to radiation safety management.Currently,most operational and under-construction fusion facilities are magnetic confinement fusion plasma physics experimental devices with hydrogen as the working medium.The primary radiological risks of these devices stem from radiation impacts induced by runaway electrons under accident scenarios.This study investigates the radiological consequences of runaway electrons in magnetic confinement fusion devices through mechanistic analysis of generation processes,theoretical dose estimation,and monitoring data evaluation.Radiation protection recommendations are subsequently proposed to mitigate identified risks.
