摘要
通过分析堆外核仪表系统的功率量程和中间量程的性能,使用堆外核仪表中间量程的测量信号进行动态刻棒试验数据验证。验证结果表明,基于堆外核仪表系统中间量程的动态刻棒试验可作为传统动态刻棒试验的一种手段,其测量误差在验收准则允许范围内,且无需进行本底电流测量即可减少动态刻棒测量时间。
By analyzing the performance of power range and intermediate range of the ex-core neutron flux measurement system(RPN), the data verification of the Dynamic Rod Worth Measurement(DRWM) was carried out using the measuring data of the intermediate range. The results show that it can be used as an alternative means to the traditional DRWM. Its measurement error is within the allowable range, and it is unnecessary to measure the background current with the use of DRWM based on the intermediate range of the ex-core RPN, which can reduce the dynamic carving time.
