噪声法测量临界装置温度系数实验研究
|
摘要
为了用噪声法测量核电站反应堆的负慢化剂反应性温度系数(MTC),本文在铀溶液临界装置上研究噪声法实验测量反应性温度系数αT,并与周期法测量的αT进行比较。结果表明,两种方法测量的αT趋势基本一致。由于铀溶液临界装置中溶液的反应性温度效应与核电站反应堆的慢化剂温度效应的机理相似,因此本文利用噪声法测量铀溶液临界装置的αT对于核电站反应堆利用噪声法测量MTC有一定的参考价值。
In order to apply the noise analysis method to measure moderator temperature coefficient of reactivity(MTC)to the reactors of power plants,the uranium solution temperature coefficient of reactivityαTfor the uranium solution critical assembly was measured by using the noise analysis method in this paper,and the result was compared with theαTfrom the period method.The results show that the trend of the results from two measurement methods is similar.Because theαT of the uranium solution critical assembly is similar as the MTC of nuclear power plant in the influence of the reactivity change mechanism,using the noise analysis method to measure theαT of the uranium solution critical assembly has some meaningful experience for nuclear power plant to measure MTC.
