Choice of APCS for NPP Based on a Set of Reliability and Risk Criteria

详细

The normative documents for calculating reliability and risk indices when designing and operating APCS are analyzed. The primary groups of standards concerning reliability and risk are examined. It is concluded that the basic criteria for choosing and validating the use of APCS equipment for NPPs need to be reexamined. A set of indices which are expedient for describing automation systems, validating the choice of structure, and using specifi c equipment is formulated on the basis of the analysis.
