为处理CEFR反应率相对分布实验准备数据,研制了活化法测量反应率相对分布实验数据处理程序。步骤如下:1)推导了活化法测量相对反应率计算表达式,引入功率归一因子,以便将径向各测点的照射功率归一到相同水平;2)推导了热堆轴向、径向中子注量率相对分布曲率拟合计算公式;3)推导了快堆中子注量率分布三次样条函数拟合计算表达式。
In order to deal with the relative distribution of the CEFR response rate of the experimental preparation of data, developed activation method to measure the relative distribution of the reaction rate experimental data processing procedures. The steps are as follows: 1) Derive the calculation formula of measuring the relative reactivity rate by the activation method and introduce the power normalization factor so as to normalize the radiation power of each radial point; 2) 3) The expression of cubic spline function fitting for neutron fluence rate distribution is deduced.
