Method, device, equipment and medium for repairing nuclear power plant equipment failure

Abstract

The application discloses a kind of nuclear power plant equipment fault overhauling method, device, equipment and medium.The method comprises: when detecting the fault overhauling request of nuclear power plant equipment, control nuclear reactor to enter hot shutdown state, and control main pump to be in outage state;Based on the passive natural circulation of primary loop system, maintain nuclear reactor in hot shutdown state, and perform repair work;After repair work is completed, control main pump is switched from outage state to start state, and control nuclear reactor is switched from hot shutdown state to operating state.The technical scheme of the embodiment, after nuclear power plant shutdown, by using the passive natural circulation ability of primary loop system, maintain nuclear reactor in hot shutdown state, can shorten the temporary shutdown time when nuclear power plant equipment fault is overhauled, can improve the power generation efficiency of nuclear power unit.
