Digital Design and Reliability Analysis of Reactor Power Control System

This paper introduces a digital design of rod control and position indication (RCPI) system, in which digital control, network control, redundancy and autonomy control technology are employed to achieve the distributed control of reactor power. The system can help avoid the excessive centralization of failure risk and improve the capability of data processing, central monitoring and the maintainability, reliability and security of the system. The modularized program design can strengthen the readability and practicability, shorten the program scanning time and accelerate the response rate. A synthesis analysis of the way to enhance the reliability of reactor digital control system is also conducted. The feasibility and rationality of the designed system have been proved in a practical reactor operation.
