摘　　要：反应堆如发生燃料破损,^(131)I等裂变气体会通过破损包壳释放到厂房中增加人员内照射风险。以CPR1000机组为例分析表明:即使1根燃料棒破损也会对工作人员带来内照射风险,破损达运行限值0.25%时,即使投运净化系统,也需对人员采取防护措施。本文结合实际核电厂运行经验探讨了放射性碘危害的控制和防护措施。If the fuel rods of nuclear reactor are damaged, the fission gases such as ^131I will be released to the reactor building, increasing the risk of internal exposure to personnel. The analysis on CRP1000 unit showed that it can lead to the internal exposure risk to personal even if only one of the fuel rods is damaged As the fuel damage increased to 0. 25% of operation limitation, protective measures are required even if the purify system is turned on. The radioiodine hazard control and protection measures of ^131I are discussed with reference to the practical nuclear power plant operation experience.
