Data processing method and device for primary loop hydrostatic test of nuclear power plant and medium

The invention relates to a data processing method and device for a primary loop hydrostatic test of a nuclear power plant, computer equipment, a storage medium and a computer program product. The method comprises the following steps: according to a final safety analysis report, determining a target accident causing the pressure of a loop system to exceed a preset design pressure; determining a target originating event class matched with the target accident from the originating event class set; determining the occurrence frequency of the target originating event class according to the preset historical event information of the nuclear power unit; determining corresponding fracture possibility grades of pipelines in the primary loop system and the support system connected with the primary loop system; determining an evaluation result according to the fracture possibility grade corresponding to the pipeline, the occurrence frequency of the target originating event class and a probability safety analysis model; t
