28、ard During the work to create a standard for the design of control rooms of nuclear power plants, it became obvious that the volume of such a standard would become very large. Therefore the standard was split into one main standard (IEC 60964 with an annex) and some supplementary standards. This sta

29、ndard is one of the supplementary standards. It is intended that the Standard be used by operators of NPPs (utilities), designers, systems evaluators and by licensors. b) Situation of this Standard in the structure of the IEC SC 45A standard series IEC 61772 is the third level IEC SC 45A document ta

30、ckling the generic issue of use of VDUs in NPPs Main Control Room. IEC 61772 is to be read in conjunction with IEC 60964 which is the appropriate IEC SC 45A document which provides general requirements concerning the design of Nuclear Power Plants main control rooms. IEC 61227, IEC 61771, IEC 62241

31、and IEC 61839 should also be read with this standard. For more details on the structure of the IEC SC 45A standard series, see item d) of this introduction. c) Recommendations and limitations regarding the application of this Standard It is important to note that this Standard establishes no additio

32、nal functional requirements for safety systems. To ensure that the Standard will continue to be relevant in future years, the emphasis has been placed on issues of principle, rather than specific technologies. d) Description of the structure of the IEC SC 45A standard series and relationships with o

33、ther IEC documents and other bodies documents (IAEA, ISO) The top-level document of the IEC SC 45A standard series is IEC 61513. It provides general requirements for I giving examples of good practice and guiding the designer to avoid deficiencies of design. This standard contains: a) requirements f

34、or 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, b) requirements for g

35、ood presentation such as: 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 orient

36、ed 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, c) methods for easy and quick access to the specific information of current interest: b

37、y 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 presen

38、tation (triggered by any binary signal, such as an alarm), d) design criteria to obtain appropriate reliability of all functions necessary to achieve the specified information goals. BS EN 61772:201361772 IEC:2009 9 This standard is intended for application to the design of new main control rooms in

39、 nuclear power plants designed to IEC 60964 and where this is initiated after the publication of this standard. If it is to be applied to existing control rooms or control areas designs, care should be taken as some assumptions made (such as automation level) may not apply. Where a deviation from th

40、is standard is necessary in a back-fitting application the reasons should be documented. 2 Normative references The following referenced documents are indispensable for the application of this document.

45、r a format-set. The existence of this additional capability of display may be indicated by certain icons (navigation targets, as integrated parts of the displayed information) and their selection will lead to the display of single formats or pictorial menus or, where suitable, alpha-numeric menus 3.
