AI Technical Summary
Technical Problem
In existing technologies, when the residual heat removal system of a nuclear reactor malfunctions, the cooling efficiency is low, and the safety of the reactor core cannot be effectively guaranteed.
Method used
By monitoring the coolant flow rate, once an abnormality is detected in the waste heat removal system, the first loop is shut down, and the second loop, which contains the steam generator and main pump, is started to achieve forced circulation cooling.
Benefits of technology
It improves the cooling efficiency of the nuclear reactor when the residual heat removal system malfunctions, maintains normal unit operation, avoids entering accident procedures, and reduces the pressure on operating personnel.

Abstract
本申请适用于核电技术领域，提供了一种核反应堆的冷却控制方法、装置、控制设备及计算机程序产品。冷却控制方法包括：确定核反应堆的余热排出系统是否工作异常；若是，则控制余热排出系统对应的各个第一环路停运，并控制核反应堆的蒸汽发生器和主泵所在的各个第二环路中的任意一个第二环路运行。通过本申请的冷却控制方法，当核反应堆的余热排出系统工作异常时，控制核反应堆的蒸汽发生器和主泵所在的各个第二环路中的任意一个第二环路运行，从而通过该运行的第二环路对核反应堆进行冷却，相较于现有技术中通过自然循环冷却的方式，本方法能够提高余热排出系统工作异常时对核反应堆的冷却效率。
