According to the study of series of related standards, the defense-in-depth and diversity have become the basic requirements for digital I&C and should be strictly followed when carrying out the overall scheme design of Digital Control System, in which the risk of Common Cause Failure has to be prevented or coped with. This paper analyzes the requirements according to the diversity principle and illustrates the typical solution of the diversified protection base on the CPR1000 NPP. Some concepts will be helpful to the design of DCS.
