Abstract

Abstract

In allusion to the problem of water supply control caused by the strong coupling of casing steam generator, the steam-water circulation system of commercial modular small reactor with casing steam generator is taken as the research object, and the simulation model of steam-water circulation system is established based on the software APROS. The steady-state simulation results show that the simulation model has high simulation accuracy and meets the requirements of simulation analysis. Through the transient simulation test of power load increasing and decreasing, the transient operation characteristics of casing steam generator are studied. The research results show that steam and feedwater flows have good load following characteristics when the traditional control scheme is adopted, but relatively large steam pressure fluctuation can be observed, and the steam dump will be triggered when 80%FP drops to 50%FP. To solve this problem, an optimization scheme of feed water control is proposed. The simulation analysis results show that the fluctuation range of steam pressure is obviously reduced after optimization, and the steam dump action is not triggered, and the safety and stability of the system are effectively improved.
