摘　　要：在钠冷快堆中,为减少在乏燃料贮存池内和后续运输途中对周围环境的放射性污染,需要有效地识别出清洗阱内的破损乏燃料组件。结合乏燃料组件清洗工艺,根据包壳破损特征核素的特性和本底放射性水平,设计了有效的包壳破损探测方法,并探讨了包壳破损的判定依据,以可靠地识别出钠冷快堆各种不同性质和不同时期破损的乏燃料组件。In order to reduce radioactive contamination,it is necessary to identify the failed spent fuel assemblies in the cleaning trap for sodium-cooled fast reactor.Combined with spent fuel assembly cleaning process,an effective failed fuel detection damage method is designed based on the characteristics of the characteristic nuclides and the background radioactivity level,and failed fuel judgment basis has been researched.This design could reliably identify the failed spent fuel assemblies with various cladding ruptures.
