Abstract

Abstract

Based on the manual operational experience in the reactor cold start-up, the paper presents two automatic control methods for reactivity insertion from nuclear reactor cold start-up to critical. The effect of the control algorithm is verified by a simulation experiment, with which the point reactor model with six delayed neutrons is utilized. The results show that the designed method can control the reactor to be critical automatically by inserting the reactivity timely and properly.
