The invention belongs to the technical field of nuclear power, and particularly relates to an equipment-based knowledge graph construction application method and device for a nuclear power plant. According to the method, nuclear power plant equipment is taken as a center, materials of the equipment in the whole process from design, construction, installation, debugging, operation to decommissioning are collected and sorted, and the materials comprise design drawings, design manuals, debugging manuals, operation regulations, maintenance regulations, maintenance schemes, event reports, quality defect reports and papers related to the equipment; and purchasing and storing spare parts, risk analysis, manufacturers and the like to form a knowledge base. A knowledge graph model taking equipment as a center is constructed by utilizing a knowledge graph and a machine learning technology, and a nuclear industry semantic library is perfected. By combining natural language processing, intelligent question and answer and
