研究了压水堆从冷停堆状态达到临界状态的自动启堆控制方法。参照手动启堆操作过程,设计了2种反应性引入自动控制算法;利用6组缓发中子点堆模型,对控制方法的效果进行了模拟仿真实验验证。结果表明,所设计的算法能够通过适时地控制引入反应性,使反应堆达到临界状态。 The method of automatic stack-start control for pressurized water reactors to reach a critical state from a cold shutdown state is studied. With reference to the manual opening operation process, two kinds of reactivity introduction automatic control algorithms are designed. Six groups of delayed neutron point reactor models are used to verify the effectiveness of the control method. The results show that the proposed algorithm can achieve the critical state of the reactor by controlling the introduction reactivity timely.
