Design and implementation of main control unit for nuclear-level instrument control system based on domestic chips

Abstract： The nuclear power instrument and control(I&C) system is related to the country′s nuclear power safety. It is very important to use domestic chips to realize the I&C system. Only based on the domestic technology platform can guarantee the safety of the nuclear-level I&C system internally. In the process of implementing the instrument and control system based on domestic chips, we are faced with the problems of system design, device selection, and how to meet the stability, reliability, independence and certainty of products under the new system architecture. This paper presents the design and implementation of the control principle of the nuclear-level instrument and control system based on domestic chips and computer technology platform, and focuses on the independent and deterministic design. In this paper, the performance indicators of the main control unit are measured. The results show that the control system realized by using domestic chips meets the requirements of key indicators. The design and implementation of the main control unit has reference significance for the localization of nuclear power I&C systems.
