The evolution of automated process control systems at nuclear power plants from traditional automation means with hard-wire logic based on archaic means – arrow instruments, recorders, light indicators, keys for individual equipment control etc., up-to-date automated information and control systems based on high-level software and hardware. Characteristics of the features that affect the design decisions for the process control system, such as the continuity of processes, the variety of equipment and accessories, the complexity and heterogeneity of software and hardware, the centralization of information, and so on. It is shown that modern automated process control systems for nuclear power facilities should contain a upper level system. The general architecture of such a system is considered and its composition is presented on the example of the automated process control system for NVNPP-2 A detailed analysis of the problems of the functioning of this system, consisting in ineffective operation of the communication busbars due to avalanche-type information processes in the transmission of broadcast messages, which paralyzes the network and automated process control system in a whole. Priority measures aimed to improve stability of the automated process control system are proposed: automatic recovery of operability within a specified time, elimination of false operation of controllers and interlocks, visualization of information by parameters from safety panels and common display. The analysis of the issues of cybersecurity of the information subsystems of the automated process control system of nuclear power plants was carried out and a solution was proposed to increase the level here by duplicating and reserving data transmission channels.
