3 MeV中子诱发裂变测定铀同位素丰度

Determination of Uranium Isotope Abundance by 3 MeV Neutron Induced Fission

摘要: 铀同位素丰度分析是核燃料循环中重要的分析项目。本工作研究了以D(d,n)³He反应产生的能量约为3 MeV的中子为源诱发裂变测定铀同位素丰度，并与以T(d,n)⁴He反应产生的14 MeV快中子为源的方法进行了比较，结果表明两种方法分析结果基本一致。

Abstract: The determination of uranium isotope abundance is the important analysis item in nuclear fuel cycle. The determination of uranium isotope abundance by fission induced by 3 MeV neutron from D(d,n)³He was studied, and compared to the method using 14 MeV fast neutron from T(d,n)⁴He. The result shows that they are coincident.
