Abstract: With the rapid development of artificial intelligence technology in recent years, AI drawing review technology has received extensive attention in the industry. This paper combines the research results of Tsinghua University and China National Nuclear Corporation on AI drawing review technology to empower nuclear power fire safety, and expounds the "TuZhi" system and its application practice in fire protection review in nuclear power industry. Practice in this paper has shown that AI drawing review technology can be effectively applied to actual PDF construction drawings such as industrial plants and warehouses, which helps find fire safety problems that violate the provisions of national fire protection regulations. AI drawing review technology has significant advantages in comprehensive, objective, and consistent reviewing, as well as its solidification and reuse of industry knowledge. The AI drawing review technology and its innovative application in the nuclear power industry introduced in this paper would provide a reference for the subsequent applications in smart industry.
