摘要
为实现反应堆装料至升功率期间对核裂变反应速率的密切监视,需对反应堆中子倍增时间进行正确稳定的测量。本文基于对中子注量率测量的统计特性分析,设计了一种适用于压水堆核仪表系统的倍增时间算法,并利用SCADE软件对实现了算法,同时在方家山核电工程2号机组上进行了堆上试验,试验验证了该算法的稳定性、及时性和有效性。因此,本研究设计的反应堆中子倍增时间算法能够应用于压水堆核仪表系统中子注量率测量信号的处理。
To realize the close monitoring of the nuclear fission rate of reactor during the period from fuel loading to power ascension,the correct and stable measurement of reactor neutron doubling time shall be implemented.Based on the statistical analysis of neutron fluence rate measurement,a doubling time algorithm suitable for PWR nuclear instrument system is designed and implemented by SCADE software.The in-pile test is carried out on Unit 2 of Fangjiashan nuclear power project.Tests verify the stability,timeliness and effectiveness of the algorithm.Therefore,the reactor neutron doubling time algorithm designed in this study can be applied to the processing of the neutron fluence rate measurement signal of the PWR nuclear instrumentation system.
