用硼中毒法进行脉冲堆控制棒效率和总后备反应性测量

Measurement of Control Rod Reactivity Worth and Core Total Excess Reactivity for Pulsed Reactor by Soluble Boron Poison Method

本文介绍了在脉冲堆零功率物理实验中,利用硼中毒法测量反应性的原理和方法,给出了脉冲堆堆芯的硼微分价值、控制棒效率和总后备反应性的实验结果。还利用硼中毒法和脉冲中子源法配合进行脉冲堆控制棒之间反应性干涉效应的实验研究,取得了初步结果。

In this paper, fundament and method of reactivity measured by soluble boron poison method in pulsed reactor zero power physical test are described. Experimental results of boron differential worth and contral rod reactivity effect and toal excess reactivity in pulsed reactor core are given. Experimental research of reactivity interference effects among control rods in pulsed reactor by soluble boron poison method and pulsed neutron source method are described too, some results are obtained.
