^(74)Se同位素分离研究

The Study of ^(74)Se Isotopes Separation

针对分离装置对工作介质的特殊要求,选择SeF6作为分离工作介质,并进行了单机分离试验,获得适用于级联设计的单机参数和单位质量数差的全分离系数γ0。进一步研究中,借鉴其它稳定同位素分离经验,建立了直角级联模型,并进行了级联分离计算。通过理论计算,分析了74Se同位素级联分离特性。上述研究表明,采用专用方法分离74Se同位素是可行的。

According to the special demand of a separation facility, SeF6 is selected as working midium. By dint of separation test in a separation facility, some separation characteristic parameters which are necessary for a cascade design are acquired. In the further study, a square cascade model is established, and the cascade separation characteristic of ^74Se is analyzed by the cascade theory. The studies indicate that it is feasible for separating ^74Se by the special separation facility.
