Abstract

Abstract

The heat pipe cooled reactor (hereinafter referred to as heat pipe reactor) has the design concept of solid-state reactor, and the heat is passively transferred out of the core through heat pipes. It has the advantages of simple structure, high safety, low noise, compact structure and long working time. In this paper, a 100 kW silent heat pipe reactor (NUSTER-100) is taken as the research object, and the nonlinear dynamic model is built based on MATLAB/Simulink platform. The transfer function model is obtained by linearization based on perturbation theory. Based on the analysis of dynamic characteristics, a cascade control method of electric power is proposed, in which the inner loop is the core power regulation and the outer loop is the electric power control. Based on the transfer function between reactivity and nuclear power, and the transfer function between nuclear power and electric power, an electric power cascade control system is designed, and its nonlinear problem is solved by gain scheduling. The simulation results show that the cascade control system can meet the requirements of control performance and realize the safe and reliable operation of nuclear reactor.
