【Abstract】 In order to establish a digital integrated R&D and delivery environment based on system engineering(SE), in this paper, the top-level architecture of the digital integrated R&D platform for nuclear power engineering experiments(i.e. the digital experimental system) is optimized, and the detailed architecture of functional composition and operational logic is designed.On this basis, the digital experimental system of nuclear power engineering is developed, and the experimental project of passive residual heat removal system on secondary side is used as an example for application verification. The verification results show that the established architecture of digital experimental system for nuclear power engineering can meet the requirements of digital integrated R&D and delivery of nuclear power engineering experiments, such as experimental task planning and decomposition, quality process control, tool software packaging and integration,collaborative design and simulation, knowledge accumulation and accompanying, process data tracing, and structured and lightweight delivery of experimental results, and can realize the integration of tasks, tools, knowledge, data and results, effectively improving the efficiency and quality of experimental research and development.更多还原
