Digital Twin Technology Architecture and Application for Nuclear Reactor Intelligent Operation and Maintenance

In order to improve the safety and reliability of nuclear reactors, and improve the digital and intelligent level of operation and maintenance management, a digital twin technology architecture for nu-clear reactor intelligent operation and maintenance was proposed based on the connotation analysis of nu-clear reactor digital twin technology. Based on the technical implementation framework elements and the mutual relationship, at the level of research on digital twin in nuclear reactor operations management sce-narios can assign a process, and from the perspective of technical implementation, based on the number of twin intelligence operations applications are analyzed. Digital twin has realized the organic combination of space and physical space, and can effectively support the nuclear reactor intelligence operations a variety of scenarios, realize the device efficiency gains. The research results have certain guiding significance for the application research of nuclear reactor digital twin technology and the construction of digital twin platform for intelligent operation and maintenance.
