摘　　要：核电厂反应堆次高选平均温度信号作为控制棒控制回路中重要参数之一,确保其可靠性和精度非常重要。根据控制棒动作定值和回路中给定的控制参数,在汽机负荷和核功率稳定状态下,反算出控制棒动作时对应的次高选平均温度的变化量,并通过现场模拟信号验证,证明理论计算的正确性。The second-highest selected average temperature signal of the nuclear power plant reactor is one of the important parameters in the control rod control loop,and it is very important to ensure its reliability and accuracy.According to the fixed value of control rod action and the given control parameters in the loop,under the stable state of turbine load and nuclear power,the variation of the average temperature corresponding to the secondary high selection during the control rod action was calculated.The correctness of the theoretical calculation was proved by field simulation signal verification.
