information and control systems

The article presents a new classifier of types of diversity (version redundancy) for information and control systems (ICS) of nuclear power plants, which significantly complements the well-known classifier according to the NUREG-7007 standard by adding subtypes of diversity, taking into account production processes and the capabilities of FPGA technologies. A method of expert evaluation of diversion metrics and the cost of implementing alternative architectural solutions at the ICS NPP based on the extended NUREG-7007 classifier is proposed.
