36、for reactor control systems of nuclear power plantsOctober 2011 viiPrefaceThis is the second edition of CSA N290.4, Requirements for reactor control systems of nuclear power plants. It supersedes the previous edition published in 1982. The title has been changed to reflect a change of scope. The new

37、 edition not only addresses CANDU reactors but also addresses other types of water-cooled power reactors.The development of the original Standard was initiated by the Canadian Nuclear Association to help prospective owners of nuclear power plants, as well as designers, manufacturers, fabricators, an

38、d installers of nuclear power plant components, by compiling the various requirements of regulatory authorities. Major changes to this edition include(a)broadening of requirements to incorporate other water-cooled reactor technologies; (b) improved integration with associated standards; and (c) inco

39、rporation of current terminology and operating experience.The specific objective of this Standard is to establish the minimum requirements for the design, manufacture and fabrication, qualification, and installation of reactor control systems in nuclear power plants, in order to ensure that they wil

40、l operate as intended. The purpose of this Standard is not to limit improved system design but to provide a minimum base against which innovations and new techniques can be compared.The CSA N-Series of Standards provides an interlinked set of requirements for the management of nuclear facilities and

41、 activities. CSA N286 provides overall direction to management to develop and implement sound management practices and controls, while the other CSA nuclear Standards provide technical requirements and guidance that support the management system. This Standard works in harmony with CSA N286 and does

42、 not duplicate the generic requirements of CSA N286; however, it may provide more specific direction for those requirements.Users of this Standard are reminded that the design, manufacture, construction, commissioning, operation, and decommissioning of nuclear facilities in Canada are subject to the

43、 provisions of the Nuclear Safety and Control Act and its supporting Regulations.This Standard has been prepared by the Subcommittee on Reactor Control Systems of Nuclear Power Plants, under the jurisdiction of the Technical Committee on Reactor Control Systems, Safety Systems, and Instrumentation o

44、f Nuclear Power Plants, and the Standards Steering Committee on Nuclear Standards.October 2011Notes: (1) Use of the singular does not exclude the plural (and vice versa) when the sense allows.(2) Although the intended primary application of this Standard is stated in its Scope, it is important to no

45、te that it remains the responsibility of the users of the Standard to judge its suitability for their particular purpose.(3) This publication was developed by consensus, which is defined by CSA Policy governing standardization Code of good practice for standardization as “substantial agreement. Cons

46、ensus implies much more than a simple majority, but not necessarily unanimity”. It is consistent with this definition that a member may be included in the Technical Committee list and yet not be in full agreement with all clauses of this publication.(4) To submit a request for interpretation of CSA

47、Standards, please send the following information to inquiriescsa.ca and include “Request for interpretation” in the subject line:(a) define the problem, making reference to the specific clause, and, where appropriate, include an illustrative sketch;(b) provide an explanation of circumstances surroun

48、ding the actual field condition; and(c) where possible, phrase the request in such a way that a specific “yes” or “no” answer will address the issue.Committee interpretations are processed in accordance with the CSA Directives and guidelines governing standardization and are published in CSAs period

49、ical Info Update, which is available on the CSA website at http:/standardsactivities.csa.ca.(5) CSA Standards are subject to periodic review, and suggestions for their improvement will be referred to the appropriate committee. To submit a proposal for change to CSA Standards, please send the following information to inquiriescsa.ca and include “Proposal for change” in the subject line:(a) Standard designation (number);N290.4-11 Canadian Standards Associationviii October 2011(b) relevant clause, table, and/or figure number;(c) wording of the proposed chan
