20、 the subject dealt with may participate in this preparatory work. International, governmental and non- governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with cond

21、itions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC Nat

22、ional Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the w

23、ay in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IE

24、C Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should

25、ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage

26、of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the

27、 referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

28、The main task of IEC technical committees is to prepare International Standards. However, a technical committee may propose the publication of a technical report when it has collected data of a different kind from that which is normally published as an International Standard, for example “state of t

29、he art“. IEC 62096, which is a technical report, has been prepared by subcommittee 45A: Instrumentation and control of nuclear facilities, of IEC technical committee 45: Nuclear instrumentation. This second edition cancels and replaces the first edition published in 2002. This edition includes the f

30、ollowing significant technical changes with respect to the previous edition: update on the format to align with the current IEC/ISO directives on style of documents; update on references, taking into account Standards published since the first edition; update on the terminology; TR 62096 IEC:2009 5

31、incorporation of a number of clarifications proposed by National Committees. The text of this technical report is based on the following documents: Enquiry draft Report on voting 45A/711/DTR 45A/726/RVC Full information on the voting for the approval of this technical report can be found in the repo

32、rt on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. The committee has decided that the contents of this publication will remain unchanged until the maintenance result date indicated on the IEC web site under “http:/webstore.

33、iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 6 TR 62096 IEC:2009 INTRODUCTION a) Technical background, main issues and organisation of this Technical Report Normal procedures for eval

34、uation of plant safety, operations and maintenance provide information about potential needs for renewal or upgrades. After many years of operation, the Instrumentation & Control (I&C) systems may no longer fulfil actual or anticipated safety requirements, may be obsolete or unreliable, or may no lo

35、nger be fit for required lifetime extensions. In such cases, modernization provides the way forward to adapt the I&C systems to meet the requirements or to deal with the problems and costs caused by the obsolescence or aging of the equipment. During modernization, the benefits offered by modern I&C

36、equipment can be evaluated. It is intended that this Technical Report be used by operators of NPPs (utilities), systems evaluators and by licensors. b) Situation of the current Technical Report in the structure of the IEC SC 45A standard series IEC 62096, as a Technical Report, is the fourth level I

37、EC SC 45A document tackling the issue of guidance for decision for modernisation. For more details on the structure of the IEC SC 45A standard series, see d) of this introduction. c) Recommendations and limitations regarding the application of this Technical Report There are no particular recommenda

38、tions, neither limitations regarding the use of this Technical Report. d) Description of the structure of the IEC SC 45A standard series and relationships with other IEC documents and other bodies documents (IAEA, ISO) The top-level document of the IEC SC 45A standard series is IEC 61513. It provide

39、s general requirements for I&C systems and equipment that are used to perform functions important to safety in NPPs. IEC 61513 structures the IEC SC 45A standard series. IEC 61513 refers directly to other IEC SC 45A standards for general topics related to categorization of functions and classificati

40、on of systems, qualification, separation of systems, defence against common cause failure, software aspects of computer-based systems, hardware aspects of computer-based systems, and control room design. The standards referenced directly at this second level should be considered together with IEC 61

41、513 as a consistent document set. At a third level, IEC SC 45A standards not directly referenced by IEC 61513 are standards related to specific equipment, technical methods, or specific activities. Usually these documents, which make reference to second-level documents for general topics, can be use

42、d on their own. A fourth level extending the IEC SC 45A standard series, corresponds to the technical reports which are not normative. IEC 61513 has adopted a presentation format similar to the basic safety publication IEC 61508 with an overall safety life-cycle framework and a system life-cycle framework and provides an interpretation of the general requirements of IEC 61508-1, IEC 61508-2 and IEC 61508-4, for the nuclear application sector. Compliance with IEC 61513 will facilitate
