Weichao He, Yuguang Niu, Shuangfeng Dai, Ming Du · 2024
As a means to improve the reliability of digital instrument control system of nuclear power plant, redundancy technology is more and more adopted by modern industrial designers, and it plays an increasingly important role in modern nuclear power industry production. The system designer can improve the reliability of the system through equipment redundancy, software redundancy and redundancy technology, and meet the requirements of safe operation of the important load system. This paper summarizes the typical application mode of the control system redundancy technology in nuclear power plant, models the typical system redundancy structure, and completes the failure probability analysis. Finally, other technologies of the reliability design of the instrument control system in nuclear power plant are described.
