Abstract

Abstract

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.
