摘要
Abstract
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.关键词
