Abstract

Helium-xenon cooled reactor Brayton cycle system (He-Xe reactor system) has the advantages of high efficiency, small volume and mass, and simple construction, which is very suitable for remote island nuclear power plant. It is great significance for the safety control and operation of He-Xe reactor system to design a variety of single line and composite bypass controls and study the transient response characteristics of the system after the control is introduced. In this paper, a variety of single line and composite bypass control are designed. Through the developed system analysis program, the transient working conditions of He-Xe reactor system under various single line and composite bypass control are simulated, and the transient control characteristics of various single line and composite bypass control are analyzed. Finally, the control characteristics are evaluated to find the optimal solution. The results show that various single line bypass controls have the ability to reduce the system output power and rotation rate, and can be used as protection control for accidents such as load loss, positive reactivity introduction and volume incorrect charging. In the single line bypass control, the compressor outlet bypass control is better than the turbine inlet bypass control. The compressor outlet bypass control 2 is excellent in control effect, reactor temperature and power, cooler power and system maximum pressure, and the activation of the control will only cause the maximum temperature and maximum pressure of the system to increase and decrease by 0.19 % and 1.44 % respectively. Therefore, it is evaluated as the best single line bypass control. In the composite bypass control, the reactor temperature and power have the law of mutual constraint. The control effect of rotation rate and system output power can be superimposed by increasing the mass flow rate of any single line bypass control. Composite bypass control 4 is the best composite bypass control. Various single line and composite bypass controls require cooling water mass flow rate or temperature control as an auxiliary.
