Method, device, equipment and medium for optimizing safety injection logic test of nuclear power station

The invention relates to the technical field of periodic tests, and discloses a safety injection logic test optimization method and device for a nuclear power station, equipment and a medium. The method comprises the following steps: in the process of performing a safety injection logic experiment on the nuclear power plant, if it is detected that fault scene simulation of the nuclear power plant is ended, controlling a small-flow electric valve on an RCV pump small-flow pipeline of the nuclear power plant to be started, and after the small-flow electric valve is started, starting the RCV pump small-flow pipeline of the nuclear power plant; and the adjustable isolating valve is controlled to be adjusted from the closed state to the completely-opened state within the set opening duration range so that reactor coolant can be slowly injected into a first sealing leakage flow pipeline of a main pump of the nuclear power plant through the RCV pump small-flow pipeline, and the adjustable isolating valve is installe
