摘　　要：国内两台核电机组分别安装了1套由中国原子能科学研究院研制的燃料破损在线探测系统(FDDS)。通过FDDS对两台核电机组发生燃料破损时的连续监测和分析,表明FDDS在核电厂一回路放射性核素活度浓度在线测量及燃料破损监测中发挥了良好的作用,弥补了化学取样分析方法的不足。The on-line fuel damage detection system(FDDS)developed by the China Institute of Atomic Energy was installed respectively in two domestic nuclear power units.By continuously monitoring and analyzing fuel damage in two nuclear power units,the results show that FDDS plays a good role in on-line measurement of primary circuit radioactive nuclide activity concentration and fuel damage monitoring in these plants,and makes up for the shortcomings of chemical sampling analysis method.
