Personnel Requirements, Qualifications, and Training9.1 The facility owner/operator shall specify the require-ments and guidelines for qualification and tra

32、ining of personnelinvolved in the coatings performance monitoring program.Unless otherwise required in the licensees QA program orlicensing commitments, individuals who perform and coordi-nate coating condition assessment shall be knowledgeablecoatings personnel. Should the assessment determine that

33、specific quantitative follow-up inspection is needed, individu-als performing that inspection shall meet the requirements ofGuide D 4537 for Level I inspection or ANSI N45.2.6.9.2 The evaluator shall be a person knowledgeable andexperienced in nuclear coatings work.10. Inspection Plan10.1 The owner/

34、operator shall develop a plant specificinspection plan to accomplish the objectives of the monitoringprogram. A general visual inspection shall be conducted on allreadily accessible coated surfaces during a walk-through. AfterD 5163 05a2the walk-through, thorough visual inspections shall be carriedo

35、ut on previously designated areas and on areas noted asdeficient during the walk-through.Athorough visual inspectionshall also be carried out on all coatings near sumps or screensassociated with the Emergency Core Cooling System (ECCS).The inspection plan shall address the following based onspecific

36、 owner/operator requirements:10.1.1 A pre-inspection briefing to familiarize all personnelperforming inspection with objectives of the inspections,procedures to be followed, and precautions to be taken,10.1.2 Monitoring team(s) assignments to specific areas forinspection(s), and10.1.3 Location maps

37、dividing the plant into identifiableareas for inspection activities to be issued to inspection teams.The maps shall also identify items/areas requiring specialtesting, if any. The locations of all defects and of all testsperformed shall be recorded on the maps so that additionaltesting, recoating, a

38、nd further monitoring may be performed.10.2 During walk-through, visually examine coated sur-faces for any visible defects, such as blistering, cracking,flaking/peeling, rusting, and physical damage.10.2.1 BlisteringCompare any blistering found to theblistering pictorial standards of coatings defect

39、s (refer to TestMethod D 714) and record size and frequency. If the blistersare larger than those on the comparison photographs, measure,record size and extent, and photograph. Report if blisteredportions are intact.10.2.2 CrackingCracking can be limited to the one layerof coating or extend through

40、to the substrate. Measure thelength of the crack or if extensive cracking has occurred,measure the size of the area affected. Determine if the crackingis isolated or is part of a pattern. Record measurements anddescribe crack depth and pattern on the inspection report.Photograph the area affected.10

41、.2.3 Flaking/Peeling/DelaminationMeasure the ap-proximate size of the peels and note the pattern formed.Carefully test to see if lifting can be easily achieved beyond theobvious peeled area. Note all observations on the inspectionreport and photograph the area affected.10.2.4 RustingCompare with the

42、 pictorial standards ofTest Method D 610/SSPC-VIS 2 to determine the degree ofrusting. Try to determine the source of rusting (that is, is itsurface stain caused by rusting elsewhere, or is it a failure ofthe coating allowing the substrate to rust). Photograph theaffected area and record observation

43、s on the inspection report.10.2.5 If no defects are found, mark “Coating Intact, NoDefects” on the inspection report.10.2.6 If portions of the coating cannot be inspected, notethe specific areas on the location map-inspection report, alongwith the reason why the inspection cannot be conducted.10.3 W

44、ritten or photographic documentation, or both ofcoating inspection areas, failures, and defects shall be madeand the process of documentation standardized by the facilityowner/operator. Written documentation practices for inspectionof coating systems as given in Practice F 1130 may be adoptedas a gu

45、ideline.10.4 For coating surfaces determined to be suspect, defec-tive, or deficient, physical tests, such as dry film thickness (TestMethods D 1186 and SSPC-PA2), and adhesion (Test MethodsFIG. 1 Inspection Data SheetFIG. 2 Photographic Documentation Location MapD 5163 05a3D 3359, D 4541, or D 6677
