35、it may provide more specific direction for those requirements.Users of this Standard are reminded that the operation of nuclear facilities in Canada is subject to the requirements of the Nuclear Safety and Control Act and Regulations. The Canadian Nuclear Safety Commission might impose additional re

36、quirements to those specified in this Standard.This Standard was prepared by the Subcommittee on Periodic Inspection of CANDU Nuclear Power Plant Containment Components, under the jurisdiction of the Technical Committee on Periodic Inspection of CANDU Nuclear Power Plant Components and the Strategic

37、 Steering Committee on Nuclear Standards, and has been formally approved by the Technical Committee.Notes: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

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

39、nsus 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 Standard.4) To submit a request for interpretation of this Stan

40、dard, please send the following information to inquiriescsagroup.organd 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 surroundi

41、ng the actual field condition; andc) 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 available on the Current St

45、nment pressure suppression systems, in CANDU nuclear power plants.1.2 The inspection requirements specified in this Standard (see Annex B for additional guidance) provide assurance of the structural integrity of metallic and plastic containment system components.Note: The following are addressed by

46、other Standards or procedures as specified in Table 1:a) leak tightness and operability requirements; andb) inspection and testing requirements for concrete, embedded parts, and elastomeric seals.Periodic inspection, material property monitoring, and test programs for fiberglass reinforced plastic (

47、FRP) containment components are included in Annex A.1.3 This Standard specifies requirements fora) inspection;b) accessibility;c) inspection methods and procedures;d) personnel qualifications;e) inspection criteria;f) inspection program development;g) inspection frequency;h) evaluation of inspection

48、 results;i) disposition of defects;j) repairs;k) documentation; andl) records.1.4 In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; “should” is used to express a recommendation or that which is advi

49、sed but not required; “may” is used to express an option or that which is permissible within the limits of the standard; and “can” is used to express possibility or capability.Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.Notes to tables and figures are considered part of the table or figure and may be written as requirements.N285.5-13Periodic inspection of CANDU nuclear power plant containment componentsJuly
