摘　　要：燃料组件完整性影响着核电站的安全性和经济性。燃料组件处于高温、高压、高放射性等特殊工况,经常出现破损情况。通过监测燃料组件包壳的运行状况,及时发现、修复或更换破损燃料组件,可避免造成更大安全隐患和经济损失。编制破损燃料组件管理策略已成为压水堆核电站必要的工作。The integrity of fuel assemblies has great influences on the safety and economy of PWR nuclear power plants (PWRs). Because of the special working environment (high temperature, high pressure and intense radiation), fuel assemblies would inevitably face failures, and then degenerate during the operation of PWRs. Management of fuel assembly failures should start from the daily state detection. When fuel assemblies are found failure, they should be repaired or replaced in avoiding of more unsafe trouble and economic loss. It is necessary to develop a management strategy of the failed fuel assemblies in PWRs.
