22、ms. Refer to ASTMMNL-8, Manual on Maintenance Coatings for Nuclear PowerPlants,7and Guide D7230, which provides guidance forselecting lining materials for new construction or maintenanceof safety-related lining systems.4.2 A linings monitoring program enables early identifica-tion and detection of p
23、otential problems in lining systems.Some Coating 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 linin
24、gs may generate debris under normaloperation and testing or during upset conditions that couldadversely affect the performance of safety-related systems. Inmost cases, the consequence of the debris generation is flowblockage, essential heat transfer reduction, or both; ultimatelyleading to degradati

Responsibility5.1 The owner/operator shall identify the department orgroup within the organization responsible for establishing theapplicabl
26、e requirements for activities or procedures 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
27、 hisdesignee performing these activities 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 documentat
28、ion, and for ensuringthat personnel performing 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 li
29、ning inspection monitoringshall be determined by the owner/operator.6.2 Inspection frequency should be based on the impact oflining failures on plant safety, potential problems identifiedduring prior inspections, service life history, availability andaccessibility of the linings, considerations with
30、 respect tosatisfying “as low as reasonably achievable” (ALARA)objectives, and outage schedules. In many cases, lining condi-tion assessments can be performed in conjunction with otherroutine maintenance performed on the lined equipment (forexample, tank inspections and Generic Letter 89-13 heatexch
31、anger inspections).6.3 Inspection 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 materia
32、ls that are acceptablefor the service conditions, and quality of the application areimportant factors that determine the longevity of a CoatingService Level III system. Operating conditions also can influ-ence the service life of the linings. Flow conditions (cavitation,erosion, etc.), water chemist
33、ry, system upsets, and temperaturegradients (“cold wall” configurations) can result in prematurefailure.4Available from American National Standards Institute (ANSI), 25 W. 43rd St.,4th Floor, New York, NY 10036, http:/www.ansi.org.5Available from Society for Protective Coatings (SSPC), 40 24th St.,
