测量反应堆反应性的费曼方法综述
Research Progress of Feynman Method to Measure Reactivity
摘要: 反应性是一个间接测量的参数，文章回顾总结了费曼方法进行反应性测量的基本原理及其物理意义。就该方法在反应堆临界时的发散，两次计数的时间间隔造成计数丢失效应，使用多个探测器测量进行数据综合，中子源释放相关的中子等新问题进行了分析讨论。对费曼方法应用时仍存在的问题提出了看法。
Abstract: Reactivity is a parameter measured indirectly. The principle and physical meaning of Feynman method to measure reactivity are reviewed in this paper. Some new problems such as the diver-gence while a reactor is at critical, the count loss effect due to time interval between count-ing-gates, data synthesis technique for several sensors, correlated neutron emitted by neutron source are discussed. Finally, the author’s own opinion is put forward upon the difficulty that still exists about application of Feynman method.
