摘　　要：结合１０ＭＷ高温气冷实验堆（ＨＴＲ－１０）核蒸汽供给系统（ＮＳＳＳ）的控制系统设计，介绍了适合于高温核动力厂核蒸汽供给系统控制的一种新方法──比值控制。仿真结果表明：比值控制使堆芯氦气出、入口温度变化在允许范围内，主蒸汽温度维持为给定值。且一回路压力变化幅度不超过额定值的１０％，对堆内传热及载热能力无影响，因此，对一回路压力可不进行控制，简化了控制系统设计。Ratio control, a new control method for nuclear steam supply system (NSSS) in high temperaturenuclear power plant, is introduced by the control system design for NSSS in 10 MW high temperature gascooled test reactor (HTR-10 ). The simulation results show that the ratio control makes the heliumtemperature of the exit and the entrance to the core change among an allowable range: the temperature ofprimary steam keeps at the given value and the pressure change at the primary loop is no more than 10% ofrated vatue. The capability for heat transfer and heat removal is uninfluenced. So it is not necessary tocontrol for the primary loop pressure. The design for control system is simplified.
