19、RADIATION OF ENERGY BETWEEN 50 keV AND 7 MeV FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on al

20、l questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publi

21、cation(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in 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. IE

22、C collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions 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 op

23、inion on the relevant subjects since each technical committee has representation from all interested IEC National 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

24、 ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way 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 transparent

25、ly to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certifi

26、cation bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall

27、 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 of any nature whatsoever, whether direct or indirect, or for costs (including legal

28、 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 referenced publications is indispensable for the correct application of this publi

29、cation. 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. International Standard IEC 60532 has been prepared by subcommittee 45B: Radiation p

30、rotection instrumentation, of IEC technical committee 45: Nuclear instrumentation. This third edition cancels and replaces the second edition, published in 1992, and constitutes a technical revision. The main technical changes with regard to the previous edition are as follows: the document has been

31、 updated to take account of the requirements of IEC standards published since 1996. BS IEC 60532:2010 6 60532 IEC:2010 The text of this standard is based on the following documents: FDIS Report on voting 45B/655/FDIS 45B/670/RVD Full information on the voting for the approval of this standard can be

32、 found in the report 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 stability date indicated on the IEC web site under “http:/

33、webstore.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. BS IEC 60532:201060532 IEC:2010 7 INTRODUCTION a) Technical background, main issues and organization of the standard This Intern

34、ational Standard specifically focuses on radiation monitoring systems used for normal and incident conditions. This standard is intended for use by purchasers in developing specifications for their plant specific radiation monitoring systems and by manufacturers to identify needed product characteri

35、stics when developing systems for normal and incident conditions. Some specific instrument characteristics such as measurement range, required energy response and ambient environment requirements will depend upon the specific application. In such cases, guidance is provided on determining the specif

36、ic requirements, but specific requirements themselves are not stated except as typical examples given in informative annexes. This standard is one associated with a series of standards which cover post accident radiation monitors important to safety in nuclear power plants. The full series is compri

37、sed of the following standards: IEC 60951-1 Nuclear power plants Instrumentation important to safety Radiation monitoring for accident and post-accident conditions Part 1: General requirements IEC 60951-2 Nuclear power plants Instrumentation important to safety Radiation monitoring for accident and

38、post-accident conditions Part 2: Equipment for continuous off-line monitoring of radioactivity in gaseous effluents and ventilation air IEC 60951-3 Nuclear power plants Instrumentation important to safety Radiation monitoring for accident and post-accident conditions Part 3: Equipment for continuous

39、 high range area gamma monitoring IEC 60951-4 Nuclear power plants Instrumentation important to safety Radiation monitoring for accident and post-accident conditions Part 4: Equipment for continuous in-line or on-line monitoring of radioactivity in process stream b) Situation of the current standard

40、 in the structure of the IEC SC 45A/SC 45B standard series IEC 60951 series of standards are at the third level in the hierarchy of SC 45A standards. They provide guidance on the design and testing of radiation monitoring equipment used for accident and post accident conditions. Other standards deve

41、loped by SC 45A and SC 45B provide guidance on instruments used for monitoring radiation as part of normal operations. The IEC 60761 series provides requirements for equipment for continuous off-line monitoring of radioactivity in gaseous effluents in normal conditions. IEC 60861 provides requiremen

42、ts for equipment for continuous off-line monitoring of radioactivity in liquid effluents in normal conditions. IEC 60768 provides requirements for equipment for continuous in-line and on-line monitoring of radioactivity in process stream in normal and incident conditions. Finally, ISO 2889 gives gui

43、dance on gas and particulate sampling. The relationship between these various radiation monitoring standards is given in Table 1: BS IEC 60532:2010 8 60532 IEC:2010 Table 1 IEC SC 45A/SC 45B standards series Developer ISO SC 45A Process and safety monitoring Scope Sampling circuits and methods Accid

46、ortant to note that this standard establishes no additional functional requirements for safety systems. d) Description of the structure of the IEC SC 45A/SC 45B standard series and relationships with other IEC standards and other bodies documents (IAEA, ISO) The IEC 61508 series defines the requirem

47、ents for an overall safety life-cycle framework and a system life-cycle framework. The IEC 61508 series should be complied with when developing instruments with safety functions for radiation monitoring outside the nuclear power plant sector whilst complying with the requirements defined in this sta

48、ndard. The top-level standard of the IEC SC 45A standard series is IEC 61513. It provides general requirements for instrumentation and control systems and equipment that are used to perform functions important to safety in nuclear power plants. IEC 61513 structures the IEC SC 45A standard series.IEC

49、 61513 refers directly to other IEC SC 45A standards for general topics related to the categorization of functions and classification 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 61513 as
