摘要 反应性阶跃法和落棒法相似,均通过快速改变控制棒的位置快速改变反应堆反应性,但在实验条件上存在较大差异。本文以6群缓发中子点堆方程为基础,反应性阶跃假定为条件,得到了反应性阶跃法所适用的反应性方程,并采用CFBR-Ⅱ堆实验数据验证了该方法。 Similar with rod drop method,reactivity is changed by moving a control rod rapidly with reactivity prompt jump method.Base on 6 groups delayed neutron point kinetics equations,the reactivity equation was deduced by assuming reactivity prompt jump.And the prompt jump method was validated by experimental data on CFBR-Ⅱ.
