Abstract: The automatic control method of digitized power regulation system under square wave operation was established. The new design scheme determining the starting time of power regulation system was proposed. And the recommendation for initial adjusting rod position and positive reactor reactivity after the emission of the pulse rod was given. The new power regulation method of digitized system under square wave operation was designed, and the method was optimized and validated by Xi’an Pulsed Reactor simulation code XPRSC. The results show that the method can successfully realize the square wave operation within wider range of setting power, and can provide theoretical guidance for experiments on reactor.
