37、nts for monitoring and display of nuclear power plant safety functions in the event of an accident. It supersedes the previous edition, published in 1982 under the title Requirements for Monitoring and Display of CANDU Nuclear Power Plant Status in the Event of an Accident.Major changes to this edit

38、ion include(a) harmonization with CSA N285.0 and CSA N286;(b) the addition of an informative annex on severe accidents; and(c) the addition of information to aid in the selection of parameters to be monitored.This Standard provides requirements and recommendations for the design, manufacture, instal

39、lation, and qualification of those components specifically involved in the monitoring and display of post-accident information for a nuclear reactor. The monitoring and display of nuclear power plant variables following an accident are important safety functions; appropriate operator actions followi

40、ng such an event rely on the availability of adequate information.Users of this Standard are reminded that the design, manufacture, construction, commissioning, operation, and decommissioning of nuclear facilities in Canada are subject to the provisions of the Nuclear Safety and Control Act and its

41、supporting Regulations.This Standard has been prepared by the Subcommittee on Requirements for Monitoring and Display of Nuclear Power Plant Safety Functions in the Event of an Accident, under the jurisdiction of the Technical Committee on Reactor Control Systems, Safety Systems, and Instrumentation

42、 for Nuclear Power Plants and the Strategic Steering Committee on Nuclear Standards, and has been formally approved by the Technical Committee.March 2009Notes: (1) Use of the singular does not exclude the plural (and vice versa) when the sense allows.(2) Although the intended primary application of

43、this Standard is stated in its Scope, it is important to note 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 p

44、ractice for standardization as “substantial agreement. Consensus 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 pub

45、lication.(4) CSA Standards are subject to periodic review, and suggestions for their improvement will be referred to the appropriate committee.(5) All enquiries regarding this Standard, including requests for interpretation, should be addressed to Canadian Standards Association, 5060 Spectrum Way, S

46、uite 100, Mississauga, Ontario, Canada L4W 5N6. Requests for interpretation should(a) define the problem, making reference to the specific clause, and, where appropriate, include an illustrative sketch;(b) provide an explanation of circumstances surrounding the actual field condition; and(c) be phra

47、sed where possible to permit a specific “yes” or “no” answer.Committee interpretations are processed in accordance with the CSA Directives and guidelines governing standardization and are published in CSAs periodical Info Update, which is available on the CSA Web site at www.csa.ca.
