Abstract

Independence is one way to improve the reliability of digital instrumentation and control (I&C) system in nuclear power plant, and relevant regulation and standards give clear requirements about independence. Based on these regulation and standards, this paper briefly introduces the three means to achieve independence: electrical isolation, physical separation, communication isolation. Then it summarizes five aspects of the independence of digital I&C system. It is useful to the design and review of the digital I&C system.
