Significance and Use4.1 For conformance with the intent of the criteria listed in2.2 and 2.3, coating qualification tests are founded on plant-s

20、pecific test parameters that realistically reflect or bound thematerial and process variables that can reasonably be expectedto influence qualification testing performance.4.2 This guide provides guidance for evaluating existingcoating system qualification data for applicability to thenuclear plant

21、desiring to use a coating system not previouslyused in the plant or to qualify an existing coating system.4.3 It is recognized that new-build plants, as well as smallmodular reactors currently under development, may havedesign features that differ from those of the operating plantsthat formed the ba

22、sis for the existing test data. Therefore,careful review is required to assure that coating performancerequirements critical to the new design are adequately ad-dressed in the existing data or the need for additional coatingtesting is identified.5. Variables and Their Use5.1 Variables that can be us

23、ed to evaluate existing test dataare provided in Table 1. Also provided in Table 1 are criteria toassess the test values for each variable and a brief explanationof the significance of the variable relative to qualification of thecoating system. Each variable should be used to compare theexisting qu

24、alification test data to the respective nuclear plantslicense basis and coating qualification requirements. If com-parison of the existing test data for a given variable to theplants qualification requirements shows that the test data doesnot satisfy the criteria described in Table 1, the existing t

25、estdata is not applicable.5.1.1 Example: The existing test data shows that the test wasconducted at a peak temperature of 207F, but the plants DBApeak temperature is 238F. The DBA test data are not appli-cable to the plant because the DBAtest peak temperature is lessthan the postulated peak temperat

26、ure for the plants DBA.5.2 An example approach to evaluating existing qualifica-tion test data for applicability: A plant wants to use a singleproduct coating system to repair the existing coating systeminside reactor containment. The coating has not previouslybeen applied in the plant. The followin

31、A test reports, then satisfactory DBA testing of the coatingto the plants qualification requirements is required before thecoating can be applied in the plant as a qualified coating.5.2.7 If one or more DBA test reports are found to satisfythe criteria used in Steps 1 through 5, additional evaluatio
