Abstract

Abstract

Aiming at the interference of pulse counting in the source range of the Ex-core nuclear measurement system, a method to identify the interference of pulse counting using the average value of power spectrum of pulse counting rate as the decision value is proposed. The decision value of the average value of power spectrum is calculated according to the real reactor data, and three values are set according to the pulse counting rate size. The simulation method is used to verify the effect of interference identification, and the interference counting is superimposed on the pulse counting rate data of the real reactor. The simulation results show that the method can identify the interference signal with a duration of 1 s and an interference intensity (the ratio of interference to pulse counting rate) above 5%.
