Determination of Nuclide ~(149)Sm and ~(150)Sm in Irradiation Element of Nuclear Reactor by IDMS

    摘要
  • 摘要: 本文描述用同位素稀释质谱法测定反应堆辐照元件中~(149)Sm和~(150)Sm含量的方法步骤,研究了~(149)Sm、~(150)Sm沿反应堆元件的轴向分布规律。

     

    Abstract: The determination of nuclide ~(149)Sm and ~(150)Sm in irradiation element of nuclear reactor by IDMS is described. The axial distribution curves of nuclide ~(149)Sm and ~(150)Sm along the irradiation element are given. The error of determination is less than ±0.6％.
