Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1NOTEThe title of Guide D5163was corrected editorially in April 2009.INTRODUCTIONProtective coatings (paints) have been used extensively in t

3、he nuclear industry to protect thesurfaces of facilities and equipment 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 whic

4、h were useful in theirparticular operation. Understandably, the methods 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

5、 systematically preparespecimens and subject them to selected evaluations, 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

6、 subsequent events which might lead to the release or expulsionof a fraction 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 biologic

7、al environment during and after this improbable event. The design, fabrication,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 coati

8、ngs. If severedelamination, peeling, or flaking causes significant portions 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. S

9、afety-relatedcoatings may also exist outside of the reactor-containment.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

10、historically been covered by ANSI N5.12, ANSI N101.2, andANSI N101.4. Responsibility for updating, rewriting, and issuing appropriate ANSI replacementstandards has been transferred to ASTM, specifically ASTM Committee D33, on Protective Coatingand Lining Work for Power Generation Facilities.The obje

11、ctive of this guide is to provide a common basis on which protective coatings for thesurfaces of nuclear power generating facilities may be qualified and selected by reproducibleevaluation tests. This guide also provides guidance for application and maintenance of protectivecoatings. Quality assuran

12、ce in the nuclear industry is a mandatory requirement for all aspects ofsafety-related nuclear coatings work. Licensees of nuclear power plants are required to determine ifcoated surfaces are within the scope of 10CFR50.65, “The Maintenance Rule.” Any coated surfacesfound to be within the scope of 1

13、0CFR50.65 must satisfy the requirements of 10CFR50.65.

14、s.1. 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 guidance for applicationand maintenance of protective coatings. Under the en

15、viron-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 one, all, or acombination of the following conditions: ionizing radiation;con

16、tamination 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 Documents 2Terminology 3Significance and Use 4Coating Material Testing 5Thermal
