脉冲堆动态引发过程中初始反应性的测量

摘要

提出了脉冲堆动态引发过程中初始反应性测量的当量外推方法,由逆动态反应性测量系统、控制棒定位监测系统和裂变脉冲波形测量系统共同获得的数据而得到系统的反应性.此方法在裂变脉冲动态引发实验中成功地得到了应用,获得了初始反应性及其分布.%The method of equivalent extrapolation is presented for measuring initial reactivity in the dynamic process of initiating burst reactors. Through this method the reactivity is extrapolated from the data acquired by the reactivity measurement system of the reverse dynamic point reactor model,the measurement system of orientation of control rods and the measurement system of pulse waves. The initial reactivity and its distribution are acquired successfully using the method of equivalent extrapolation in the experiment of initiating pulses on the dynamic state.
