Abstract
The systems/equipment of nuclear power plant are complicated, the start-up and shutdown process is timeconsuming, the workload of the operating personnel is large, and human errors such as missed operations and malfunctions are prone to occur. Research and development of Automatic Nuclear Power Plant Start-up and Shutdown System (ANPS) can, on the one hand, reduce the workload of operation personnel and human errors such as mis-operation; on the other hand, it can standardize the operation procedures for start-up and shutdown of nuclear power plants and achieve "staff reduction and efficiency enhancement", which is of great practical significance to enhance the safety and economy of nuclear power plant.
This paper takes pressurized water reactor (PWR) nuclear power plant as the research object, and proposes a general technical solution of ANPS system for nuclear power plants based on the design experience of automatic start-stop technology in related industries and the specific needs of the nuclear power industry, including: functional requirements, usage requirements and functional architecture; then identifies common and dedicated key technical difficulties that may be involved in the development process of ANPS system, and conducts a preliminary assessment of technical feasibility.
