NITI’s basic trends in the design of NPP control rooms are:

• Development of NPP control concept
• Integrated design of NPP control rooms
• Design of human-system interface for NPP operators

The NPP control concept is being developed to establish principles and conceptual design solutions for controlling NPP processes in order to generate electricity and ensure NPP safety under all operating modes.

The development of the NPP control concept includes the analysis of the NPP Customer’s requirements and the definition of the following:

• The types of NPP process control used and approaches to their implementation
• Approaches to the level of process automation in various operating modes of nuclear power plants, including accidents, considering the requirements of the Customer of the NPP on the number of operational personnel of the NPP
• Hierarchical structure of NPP technological functions considering the requirements of IEC 61839 (GOSR R IEC 61839), NUREG-0711 rev.3
• Approaches to the formation of NPP control rooms: main control room, emergency control room, central control room and local control rooms
• Conceptual solutions for control and management tasks in control rooms: workplaces, human-system interface, alarm system
• Conceptual solutions for human factor engineering in the design, development, commissioning, and operation of the NPP main control rooms in accordance with NUREG-0711 rev.3

Integrated design of NPP control rooms is carried out in accordance with IEC 60964 (GOST R IEC 60964), IEC 60965 (GOST R IEC 60965) and, as a rule, includes the following:

• NPP functional analysis in accordance with IEC 61839 (GOST R IEC 61839), including:
  • definition of all NPP functions and tasks, control and management tasks implemented for generating electricity and ensuring the safety of the NPP
  • analysis of the main characteristics of NPP functions and tasks, control and management tasks
  • distribution of control and management tasks between a person (NPP operators) and a machine (automation equipment)
• Development of the HSI concept both for workstations based on VDU and for traditional control panels based on “mosaic” technology
• Determination of optimal HSI configurations for the personnel of control rooms considering the tasks to be solved and design requirements for redundancy and diversity
