摘　　要：为了校验非破坏性分析（ＮＤＡ）仪器——分段γ扫描吸收装置（ＳＧＳ）和有源中子井型符合计数装置（ＡＷＣＣ）的准确性，采用流动注射（ＦＩＡ）、高效液相色谱（ＨＰＬＣ）和Ｘ光荧光（ＸＲＦ）３种破坏性分析方法（ＤＡ）分析了铀冶金炉渣中铀的含量。结果表明：３种方法的分析数据符合良好，得到了铀冶金炉渣中铀含量的准确量值。核对了非破坏性分析仪器ＳＧＳ和ＡＷＣＣ分析铀冶金炉渣的结果。Uranium content in uranium metallurgical slag is determinated with three kinds of destructive analysis (DA) methods: flow inject analysis(FIA), high performance liquid chromatography (HPLC) and X ray fluorescence(XRF) to examine the accuracy of nondestructive analysis(NDA) methods for segmented gamma ray scanning system (SGS) and active well coincidence counter (AWCC).The result indicates that the analytical data of three kinds of DA methods agree with each other very well.The accurate uranium content in metallurgical slag is obtained. The results measured by NDA instruments SGS and AWCC are calibrated.
