Evolutionary Approach to the Construction of VVER Monitoring and Control Systems

Abstract

The basic differences arising between the safety standards in building the monitoring and control systems for NPP with VVER and the safety standards evolving in the present international and domestic normative documents – implementation of the concept of deeply echeloned protection in safety control of reactor installations on the basis of the principles of diversity, redundancy, independence of hardware and software means for eliminating common-cause faults – are presented.
