Abstract

Marine power reactor operation frequently, dramatic changes in the frequent need to adjust the automatic control rods. Characteristics for the reactor system and the existing computer simulation program described the existence of control rod reactivity unreasonable, is not accurate, the design of the marine reactor dynamic response of the automatic bar Simulink simulation module. The module as marine thermal parameters of fast reactor physics calculations Simulink program sub-modules, used in marine reactor simulation shows a typical dynamic process: the module can simulate the dynamic process of automatic Bang Bang and the corresponding bit of the dynamic response for marine reactor rapid calculation of the physical thermal parameters, dynamic process of marine reactor physics simulation and fast calculation of thermal parameters are important. The power of marine reactor varies frequently and acutely, which induces the frequent and acute adjustment of the automatic control rod. According to the characteristics of marine reactor and the problem of improper control rod reactivity insertion in previous literatures, the Simulink module for dynamic reactivity simulation of automatic control rod was designed and adopted as a sub-module of Simulink program for the fast calculation of the physical and thermal parameters of marine reactor. A typical dynamic process of the marine reactor was used as the benchmark, which indicates that the designed Simulink module is capable of the dynamic simulation of automatic control rod position and reactivity, and is adequate to the fast calculation of physic and thermal parameters. The Simulink module is of significant meaning to the simulation of the dynamic process of marine reactor and the fast calculation of the operating parameters
