Measurement and Analysis of CEFR Sodium Void Reactivity Effect

摘要: 本文介绍了中国实验快堆物理启动试验中钠空泡反应性效应测量试验的试验程序及测量结果评估，测量结果显示中国实验快堆典型位置钠空泡反应性价值皆为数值较大的负反应性，结果符合试验验证要求，验证了组件瞬间堵流事故专设监测系统的信号基础。并对试验进行了计算分析，试验前的分析为试验提供支持，试验验证了计算分析程序系统。

Abstract: The sodium void reactivity effect (SVRE) measuring test of China Experiment Fast Reactor (CEFR) physical start tests was described, and the measurement results were evaluated. The results met the test requirement and the signal base of CEFR total instantaneous blockage accident special inspect system. The calculation analysis of the SVRE measuring test was completed, which provided the data support before the test and verified the reliability of the analysis systems after the test. The analysis technology of the SVRE was accumulated through this research item
