Chemical efficiency control method and device of nuclear power station, equipment and storage medium

The embodiment of the invention relates to a chemical efficiency control method and device of a nuclear power station, equipment and a storage medium. The method comprises the following steps: determining monitoring values of a plurality of compounds in a nuclear power plant coolant according to a chemical efficiency evaluation instruction triggered by a user; under the condition that a compound with the monitoring value exceeding the monitoring value threshold value exists in the multiple compounds, judging whether the multiple monitoring events of the nuclear power station are abnormal or not according to the monitoring values of the multiple compounds, wherein the monitoring events limit the compound content in the coolant; and under the condition that an abnormal monitoring event exists in the plurality of monitoring events, determining a chemical efficiency control strategy of the nuclear power station based on the abnormal monitoring event so as to improve the chemical efficiency of the nuclear power st
