What is BS EN 61772 - Application of VDUs for nuclear power plants about?
BS EN 61772 is a European Standard on nuclear power plants’ control rooms. The main aim of BS EN 61772 is to provide computer-based control rooms in order to meet the new demands in controlling systems in a safe and effective way.
BS EN 61772 presents design requirements for the application of VDUs in the main control rooms of nuclear power plants.
BS EN 61772 assists the designer in specifying VDU applications (including displays on individual workstations and larger displays for group-working or distant viewing) together with or instead of conventional (panel) displays by:
- Stating principles to take advantage of VDU capability
- Giving examples of good practice and guiding the designer to avoid deficiencies of design
BS EN 61772 contains:
Requirements for information needs:
- According to information goals e.g., operation, maintenance, protection
- Allowing for the necessary amount of space, e.g., location, arrangement
- Using a hierarchy and/or relationships
- Avoiding unnecessary information
- Ensuring that information is relevant
- Clear and flicker-free display with suitable updating frequency
- Enough display space and an optimal arrangement
- Adequate format and symbol sizes
- Pictorial, symbolic display in addition to alpha-numeric capacity
- Standardized, common symbols and names
- Arrangements oriented to human factor needs, e.g. population stereotypes
- Use of grouping and coding methods
- Use of consistent flow directions
- Appropriate abstraction levels according to the needs of the different presumed users
- By simple selection of single formats or format-sets according to information goals
- By using different kinds of menus (icons of neighbouring information) or other access techniques (last display, selection on screen, etc.) by soft keys on or off the VDU screens or cursors
- By using programmed presentation (triggered by any binary signal, such as an alarm)
Who is BS EN 61772 - Application of VDUs for nuclear power plants for?
BS EN 61772 on the application of VDUs for nuclear power plants is useful for:
- Nuclear power stations
- Designers of VDU
- Atomic energy agencies
- Atomic research organizations
- NPP operators, systems evaluators and licensors
- Manufacturers of electric equipment
- Safety and regulatory authorities
Why should you use BS EN 61772 - Application of VDUs for nuclear power plants?
A visual Display Unit (VDU) is a type of display incorporating a screen for presenting computer-driven images that are commonly used in the control room for monitoring data in conjunction with the conventional panels. The VDU system shall be designed so that operators can perform their tasks correctly and promptly.
BS EN 61772 outlines the design and implementation of VDU formats, large screen displays and provides information-content of LSD formats.
BS EN 61772 provides the verification and validation of a VDU-based information system and sets out the advantages and disadvantages of a VDU-based display.
As a result, if you are a builder of nuclear power plant’s control rooms, complying with BS EN 61772 will help you in designing VDU with the goal of increasing security and improving operator efficiency within the control room.
