本工作采用Micro_trans_SPEC-100型便携式γ谱仪开展了铀富集度的现场测量方法研究。Micro_trans_SPEC系列便携式HPGeγ谱仪采用斯特林压缩机电制冷和一体化设计,不需要液氮冷却,尤其适合现场核材料的测量和分析。通过对测量条件和参数优化,分别建立了相对效率自刻度和标准刻度的铀富集度计算方法。
In this work, Micro_trans_SPEC-100 portable γ spectrometer was used to carry out on-site measurement of uranium enrichment. The Micro_trans_SPEC Series portable HPGe gamma spectrometers, powered by Stirling compressors, are electrically cooled and integrated, eliminating the need for liquid nitrogen cooling and are especially suited for on-site nuclear material measurement and analysis. Through the optimization of measurement conditions and parameters, the calculation method of uranium enrichment of relative efficiency self-scale and standard scale is established respectively.
