Abstract

In this paper, we propose a dynamic mathematical model for nuclear power plant (NPP) reactor, and give an implementation in Power System Analysis Software Package (PSASP) through a user-defined program. NPP is modeled with a bipartite model that consists of the neutron dynamics module and thermodynamics module. Through the simulation results of NPP reactor under different disturbances, a conclusion can be drawn that the temperature effect and poisoning effect are crucial to the self-stability of reactor, which is not only the basis of safe operation of the nuclear power plant but also the aim of the designing. The simulation validated the proposed NPP reactor model, and it can be packaged with the other parts of the NPP detailed model in PSASP for further usage in dynamic calculation of the power system.
