The Transient Characteristics Research of Start-stop System of Small Reactor
In order to optimize the design of the small reactor start-stop system and eliminate the poten-tial risk of engineering design,it is necessary to study the transient characteristics of the start-stop sys-tem.In this paper,the thermal hydraulic system analysis software LOCUST is used to establish a transient calculation model of the small reactor start-stop system,simulate the change of parameters in the system during the start-stop phase,and design a set of control logic based on the control card in LOCUST,the PID control is added to the liquid level and pressure control valve,and the control strategy of the liquid level and pressure of the start-stop system is verified.The results show that the pressure,liquid level,pressure regulating valve and liquid level regulating valve changes in the start-up separator meet the de-sign expectations.
