SGS 技术在放射性固体废物整备检测中的应用

摘要

介绍了利用分段γ扫描（ SGS）技术在放射性固体废物整备无损检测中的应用，根据某核科研基地废物特点建立了放射性固体废物整备处理技术路线。该技术路线利用桶装废物放射性无损检测装置，获取废物γ放射性信息，指导废物分拣及分类整备，从而将极低放废物和豁免废物从中、低放废物中分拣出来，使放射性废物达到最少化。实验结果表明桶装γ放射性废物无损检测装置具有测量性能稳、测量误差小等优点，能满足放射性固体废物检测要求。%It describes the application of segmented gamma scanner in the conditioning of radioactive solid waste,and establishes a technology for conditioning of radioactive solid waste on the basis of nuclear ? waste characteristics .The technology adopts a method of gamma non -destructive assay and acquires radioactive in-formation of waste in order to guide waste sorting and classification .The very low level radioactive waste and ex-empt waste were sorted out from low and intermediate level radioactive solid waste to minimize the radioactive waste .The experimental results show that the non -destructive assay system of gamma radioactive waste has the advantages of stable performance and small measurement error ,can meet the testing requirements of radioactive solid waste .
