Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.INTRODUCTIONProtective coatings (paints) have been used extensively in the nuclear industry to protect thesurfaces of facilities and equipmen

3、t from corrosion and contamination by radioactive nuclides inaccordance with ALARA. In the absence of a standard method of selecting, testing, and evaluatingcoatings, many sites evaluated paints by empirical tests to determine which were useful in theirparticular operation. Understandably, the metho

4、ds of testing were not uniform throughout the industry.It has been very difficult, consequently, to compare the results obtained at one site with those obtainedat another. Standard tests whereby industrial (nuclear) users of paints systematically preparespecimens and subject them to selected evaluat

5、ions, thus permitting uniform comparisons, areadvantageous, internationally as well as domestically.The designer of light water-moderated nuclear reactor systems must consider the possibility of aDesign Basis Accident (DBA) and the subsequent events which might lead to the release or expulsionof a f

6、raction of the fission-product inventory of the core to the reactor containment facility. Engineeredsafety features, principally a reactor containment facility, are provided to prevent the release of fissionproducts to the biological environment during and after this improbable event. The design, fa

7、brication,quality assurance, and testing of these engineered safety features ensure reliable operation and safetyunder all anticipated conditions.Large areas of the reactor-containment facility are painted with safety-related coatings. If severedelamination, peeling, or flaking causes significant po

8、rtions of the coating to be discharged into thecommon water reservoir, the performance of the safety systems could be seriously compromised bythe plugging of strainers, flow lines, pumps, spray nozzles, and core coolant channels. Safety-relatedcoatings may also exist outside of the reactor-containme

9、nt.This guide is the result of a comprehensive examination of the experience and data that have beendeveloped on protective coatings in the nuclear industry over approximately 40 years. Standardspertaining to nuclear coatings have historically been covered by ANSI N5.12, N101.2, and N101.4.Responsib

10、ility for updating, rewriting, and issuing appropriate ANSI replacement standards has beentransferred to ASTM, specifically ASTM Committee D-33, on Protective Coating and Lining Work forPower Generation Facilities.The objective of this guide is to provide a common basis on which to define and specif

11、y theperformance requirements for the coatings that will be used in nuclear facilities. Quality assurance inthe nuclear industry is a mandatory requirement for all aspects of safety-related nuclear coatings work.Licensees of nuclear power plants are required to determine if coated surfaces are withi

12、n the scope of10CFR50.65,“ The Maintenance Rule”. Any coated surfaces found to be within the scope of10CFR50.65 must satisfy the requirements of 10CFR50.65. ASME Section XI, Subsection IWEcontains the requirements for periodic evaluation of the reactor-containment steel pressure boundary.1Copyright

Scope1.1 This guide provides a common basis on which protec-tive coatings for the surfaces of nuclear power generatingfacilities may be qualified and selected by reproducible evalu-ation tests. This guide also provides g

14、uidance for applicationand maintenance of protective coatings. Under the environ-mental operating and accident conditions of nuclear powergeneration facilities, encompassing pressurized water reactors(PWRs) and boiling water reactors (BWRs), coating perfor-mance may be affected by exposure to any on

15、e, all, or acombination of the following conditions: ionizing radiation;contamination by radioactive nuclides and subsequent decon-tamination processes; chemical and water sprays; high-temperature high-pressure steam; and abrasion or wear.1.2 The content of this guide includes:SectionReferenced Docu

Significance and Use4.1 This guide addresses the concerns of Regulation Guide1.54 and Standard Review Plan 6.1

42、.2, and the replacement ofANSI Standards N5.12, N101.2, and N101.4. This guidecovers coating work on previously coated surfaces as well asbare substrates. This guide applies to all coating work inService Level I and III areas (that is, safety-related coatingwork). Applicable sections of this guide m

43、ay also be used toevaluate and select protective coatings for Service Level IIareas where deemed appropriate by the licensee.4.2 The testing referenced in this guide is particularlyappropriate for safety-related coatings inside the reactor-containment. Other test methods may be used for assessing th

Guidance for selecting safety-related and other coatingslocated outside the reactor-containment is provide

46、 Service Levels I andIII are different even though they are both safety-related. Thisstandard guide provides the minimum requirements for quali-fying Service Level I coatings and also provides guidance foradditional qualification tests that may be used to evaluateService Level I coatings. This stand

47、ard guide does not provideminimum requirements for qualifying Service Level III coat-ings but does provide guidance for qualification tests that maybe applicable for use in evaluating Service Level III coatings.4.4.2 Service Level I Coatings:4.4.2.1 All Service Level I coatings must be resistant to

48、theeffects of radiation and must be DBA qualified. The testspecimens shall be prepared, irradiated and DBA tested andevaluated in accordance with the requirements of:(a) Test Method D 3911 or plant specific requirements asapplicable,(b) Test Method D 4082, and(c) Specification D 5139.4.4.2.2 In addi
