摘要
介绍了CFBR-Ⅱ快中子脉冲堆的关闭系数的测量原理和方法。根据点堆模型,采用快响应的闪烁体探测器测量了多发脉冲的初始反应性和峰功率,并由两个参数拟合得出CFBR-Ⅱ堆爆发脉冲的关闭系数为8.06×10^(-18)$/f。
It describes the principium and method of measuring quench coefficient on CFBR-Ⅱ.Through the Model of Fuchs-Hansen the coefficient is obtained from peak power and super prompt reactivity of burst pulse. The two factors are measured by fast scintillator detector.The quench coefficient on CFBR-Ⅱis 8.6×10^-18 $/f fitting experimental data of peak power and super prompt reactivity.
