16、cific to This Standard:3.1.1 Coating Service Level III, nareas outside the reactorcontainment where lining (or coating) failure could adverselyaffect the safety function of a safety-related structure, system,or component (SSC).3.1.2 lining, nparticular type of coating intended forprotection of subst

17、rates from corrosion as a result of continu-ous or intermittent fluid immersion.3.1.2.1 DiscussionThe normal operating service environ-ments to which linings are subject are aggressive. As such,material and application process parameters are specialized andrequire exacting quality control measures.

18、Linings are some-times applied to heat exchangers to prevent tubesheet-to-tubesheet leakage.4. Significance and Use4.1 Establishment of an in-service linings monitoring pro-gram permits planning and prioritization of lining maintenancework as needed to maintain lining integrity and performance innuc

19、lear Coating Service Level III lining systems. For addi-tional information on nuclear maintenance coating work, referto Manual on Maintenance Coatings for Nuclear PowerPlants.74.2 A linings monitoring program enables early identifica-tion and detection of potential problems in lining systems.Some Co

20、ating Service Level III lining systems may be knownin advance to be suspect, deficient, or degraded. Monitoringlining performance will assist in developing follow-up proce-dures to resolve any significant deficiency relative to liningwork.4.3 Degraded linings may generate debris under normaloperatio

21、n and testing or during upset conditions that couldadversely affect the performance of the safety-related systems.In most cases, the consequence of the debris generation is flowblockage, essential heat transfer reduction, or both; ultimatelyleading to degradation of equipment or system performance.

22、Alinings monitoring program may be required to fulfill licensingcommitments for Coating Service Level III lining work.5. Responsibility5.1 The owner/operator shall identify the department orgroup within the organization responsible for establishing theapplicable requirements for activities or proced

23、ures covered bythis guide and shall document the scope of their responsibility.Owner/operator delegation of this responsibility to other out-side qualified organizations is permitted and shall be docu-mented.5.2 It is the responsibility of the owner/operator or hisdesignee performing these activitie

24、s to specify the detailedmethods and procedures for meeting the applicable require-ments of this guide.5.3 The owner/operator or his designee shall assign acoordinator to be responsible for supervising lining inspectionactivities, data collection and documentation, and for ensuringthat personnel per

25、forming inspection are adequately trainedand qualified.5.4 The owner/operator shall assign responsibility for evalu-ating the results of inspection activities carried out under thelinings performance monitoring program.6. Frequency6.1 Frequency of in-service lining inspection monitoringshall be dete

26、rmined by the owner/operator.6.2 Inspection frequency should be based on the impact oflining failures on plant safety, potential problems identifiedduring prior inspections, known service life history, availabilityand accessibility of the linings, considerations with respect tosatisfying “as low as

27、reasonably achievable” (ALARA) objec-tives, and outage schedules. In many cases, lining conditionassessments can be performed in conjunction with otherroutine maintenance performed on the lined equipment (forexample, tank inspections and Generic Letter 89-13 heatexchanger inspections).6.3 Inspection

28、 frequencies may change based on the assess-ment findings. Should two or more consecutive inspectionsindicate satisfactory conditions, then frequencies of futureinspections can be adjusted accordingly.7. Records and Past History7.1 Surface preparation, lining materials that are acceptablefor the ser

29、vice conditions, and quality of the application areimportant factors that determine the longevity of a CoatingService Level III lining system. Operating conditions also caninfluence the service life of the linings. Flow conditions(cavitation, erosion, and so forth), water chemistry, systemupsets, an

30、d temperature gradients (“cold wall” configurations)can result in premature failure.7.2 Initial assessments shall include a review of the pastlining history. Past lining history data to be reviewed mayinclude:7.2.1 Copies of lining specifications, manufacturers prod-uct data sheets, and application

31、procedures for in-place linings.7.2.2 Quality control documentation for the existing in-place lining systems and their application.7.2.3 Copies of previous inspection or monitoring reports.7.2.4 Documentation pertaining to any maintenance workperformed on in-place lining systems.7.2.5 Review of indu

32、stry operating experience for the liningmaterial.7.3 Assessments shall always include a review of the lasttwo or more performance monitoring reports, if available,pertaining to the lining systems and may include review of7.2.1-7.2.5.8.

Inspection Plan10.1 The owner/operator shall d

40、evelop a plant-specific in-spection plan to accomplish the objectives of the monitoringprogram. The plan may reference other plant programs thatdictate inspection frequency or identify required linings inspec-tions. The inspection plan shall address the following based onspecific owner/operator requ

41、irements:10.1.1 A pre-inspection briefing to familiarize programpersonnel with the objectives of the inspections, the proceduresto be followed, and the precautions to be taken;10.1.2 A listing of the required assessment frequencies foreach system segment or component; and10.1.3 Maps, drawings, or vi

42、sual media depicting the spe-cific systems and components to be inspected. These shall beused to document the locations of all defects and all tests thatare performed. These may also be used as a tool to identifyadditional testing, relining, and further monitoring.10.2 Condition assessments shall in

43、clude a visual inspectionof the designated lined surfaces to identify defects, such asblistering, cracking, flaking/peeling/delamination, rusting, andphysical damage.10.2.1 BlisteringCompare any blistering found to theblistering pictorial standards for coatings defects (refer to TestMethod D 714) an

44、d 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. Report if there is blister fluid. If fluid ispresent, samples may be taken.10.2.2 CrackingCracking can be limited t

45、o the one layerof a lining system or can extend through to the substrate.Measure the length of the crack or, if extensive cracking hasoccurred, measure the size of the area affected. Determine ifthe cracking is isolated or is part of a pattern. Recordmeasurements and describe crack depth and pattern

46、 on theinspection report. Photograph the area affected.10.2.3 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.
