The invention particularly relates to a nuclear power plant maintenance auxiliary decision-making method based on a knowledge graph. The method comprises the following steps: step 1, constructing a maintenance decision knowledge graph model; 2, on the basis of the maintenance decision knowledge graph model, combining graph database storage, nuclear power professional word segmentation, semantic similarity, a search engine and an intelligent question and answer technology to develop a maintenance decision knowledge graph system with precise retrieval and intelligent question and answer functions; and step 3, the maintenance decision knowledge graph system matches the equipment fault phenomenon input by the user to obtain corresponding equipment decision maintenance information, and assists in completing maintenance decision support. According to the nuclear power plant maintenance auxiliary decision-making method, the equipment basic information and the equipment maintenance information are pushed to the maint
