Reactor flow loss protection control method and device, computer equipment and storage medium

The invention relates to a reactor flow loss protection control method and device, computer equipment, a storage medium and a computer program product. The method comprises the following steps: obtaining reactor core power operation parameters of a reactor in a coolant loss transient state and main pump operation parameters of each main pump; determining each flow loss detection value of the reactor based on the reactor core power operation parameter and each main pump operation parameter; comparing each current loss detection value with a preset shutdown threshold value to obtain a current loss comparison result; and controlling the operation of the reactor according to the flow loss comparison result. By adopting the method, more allowance can be provided for the operation of the reactor, so that the reactor is more balanced between the operability and the safety, and the operation flexibility of the reactor is improved. 本申请涉及一种反应堆失流保护控制方法、装置、计算机设备、存储介质和计算机程序产品。所述方法包括：获取反应堆在冷却剂失流瞬态下的堆芯功率运行参数以及各主泵的主泵运行参数；基于堆
