Research Progress in Autonomous Control Strategy of Miniature nuclear reactor

Miniature nuclear reactors have great advantages in solving the energy supply in remote areas, isolated islands on the sea and other complex areas, which also put forward high requirements on the independent control ability of nuclear reactors. In this paper, the necessity of the autonomous control capability of micro nuclear reactor for its long-term stable and safe operation is discussed, and the research status, autonomous control system architecture, state detection, fault diagnosis and autonomous decision-making methods of nuclear power plant at home and abroad are summarized, and the comparison and analysis are made. It shows that the autonomous control of nuclear power plant needs further exploration in autonomous decision making, fault diagnosis, fault-tolerant control and global optimization.
