A mathematical model describing the physical, thermal and hydraulic properties of the reactor and main coolant system was established. The model uses the Emilte interpolation method to solve the point reactor kinetic equation, and other equations are solved by semi-implicit difference method. On this basis, the simulation program was compiled and the transient response characteristics of the nuclear power plant with continuous lifting rod were simulated. The comparison with the theoretical analysis shows that the simulation is in accordance with the actual situation and the numerical processing method is correct, which can be used to deal with the accident Provide basis for the safe operation of the reactor has a certain reference value
