Digital Reactor Power Control System

The reliability, safety and maintainability can be demonstrated and man-machine interface is greatly improved due to the use of digital technology in the realization of the power control system. The paper describes an ongoing research and development project of a power control system for the research reactor based on full digital technology. The contents are concerned in mechanism of power control, realized functions, structure of the system, algorithm for power regulating, and some key techniques taken in the design. Owing to the fact that the same type of digital controllers as the other parts of control system is used in the design, the power control system can be easily integrated into overall reactor control network.
