26、he 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 all questions concerning standardization in the electrical a
27、nd 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 Publication(s)”). Their preparation is entrusted to technical c
28、ommittees; 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. IEC collaborates closely with the International Organizatio
29、n 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 opinion on the relevant subjects since each technical commi
30、ttee 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 ensure that the technical content of IEC Publications is
31、 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 transparently to the maximum extent possible in their national and r
32、egional 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 certification bodies provide conformity assessment services and,
33、 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 attach to IEC or its directors, employees, servants or a
34、gents 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 fees) and expenses arising out of the publication, use o
35、f, 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 publication. 9) Attention is drawn to the possibility that som
36、e 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 60965 has been prepared by subcommittee 45A: Instrumentation, control and electrical systems of nuclear facilitie
37、s, of IEC technical committee 45: Nuclear instrumentation. This third edition cancels and replaces the second edition published in 2009. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) requireme
38、nts associated with regular testing of the supplementary control room (SCR); b) requirements to assess the time available during which the reactor will be safe but unattended, in order to move from the main control room (MCR) to the SCR and for the SCR to become operational; c) reference to SSR-2/1
39、which includes the following new requirements: 4 IEC 60965:2016 IEC 2016 1) the SCR should be functionally (as well as physically and electrically) separate from the MCR, 2) consideration shall be given to the provision of shielding against radioactivity on the access paths to the SCR; d) reference
40、to DS431, the revision of NS-G-1.3, including the following new requirements: 1) to implement at least two diverse methods for communication with a set of predefined locations, 2) to implement features to support monitoring of trends in key plant parameters; e) requirements for the role, functional
41、capability and robustness of the SCR in design extension conditions; The text of this standard is based on the following documents: FDIS Report on voting 45A/1060/FDIS 45A/1078/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the
42、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 website under “http:/webstore.iec.ch“ in the data related to the speci
43、fic publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. IEC 60965:2016 IEC 2016 5 INTRODUCTION a) Technical background, main issues and organization of the standard IEC 60965:1989 was developed to provide requirements relevant to the
44、design of NPP supplementary control points for reactor shutdown without access to the main control room. The first edition of IEC 60965 has been used extensively within the nuclear industry. It was however recognized in 2007 that technical developments especially those which were based on software t
45、echnology should be incorporated. It was also recognized that the relationships with the standard for the main control room (i.e. IEC 60964) and the derivative standards to that standard (i.e. IEC 61227, IEC 61771, IEC 61772, IEC 61839, and IEC 62241) should be clarified and conditioned. In 2009 the
46、 second edition of IEC 60965 was published. In June 2013, during the Moscow meeting, WG A8 experts recommended a limited revision be launched to take into account the lessons learned from TEPCO Fukushima Daiichi accident and some comments formulated during the circulation of the FDIS of the publishe
47、d second edition. In the course of development of this revision, the title of the standard was amended to refer to Supplementary Control Room for consistency with IAEA SSR-2/1. This IEC standard specifically focuses on the functional design process of the supplementary control room of an NPP. It is
48、intended that the standard be used by NPP designers, design authorities, vendors, utilities, and by licensors. b) Situation of the current standard in the structure of the IEC SC 45A standard series IEC 60965 is the third level IEC SC 45A document tackling the issue of the design of a supplementary
49、control room. IEC 60965 is to be read in association with IEC 60964 for the design of the main control room (including the derivative standards mentioned above) which is the appropriate IEC SC 45A document providing guidance on operator controls, verification and validation of design, application of visual display units, functional analysis and assignment, and alarm functions and presentation.
