19、an-ing3. Terminology3.1 Definitions for use with this standard are shown inTerminology D4538 or other applicable standards.4. 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-specific test parameters that r
20、ealistically 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 desiring to use a coating syst
21、em 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 basis for the existing test data
22、. 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 used to evaluate existing test d
23、ataare provided in Table 8. Also provided in Table 8 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 qualification test data to the r
24、espective 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 8, the existing testdata is not applicable.5.1.
25、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 temperature for the plants DBA.5.2 An
26、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 following describes one possibleapproa
27、ch to evaluating the existing qualification test data forapplicability to the plant using the variables in Table 8. Otherapproaches may be used. The specific variables to be used mayvary with the particular scope of the search; not all variablesmay be applicable or necessary.5.2.1 Step 1: Search the
28、 existing DBAtest reports and selectthose applicable to the coating system.5.2.2 Step 2: Review the reports selected in Step 1 andusing the variable assessment criteria for DBA testing, selectthe reports that satisfy the criteria applicable to the plant.5.2.3 Step 3: Review the reports selected in S
29、tep 2 and usingthe variable assessment criteria for Irradiation, select thereports that satisfy the criteria applicable to the plant.5.2.4 Step 4: Review the reports selected in Step 3 and usingthe variable assessment criteria for Coupon Preparation, selectthe reports that satisfy the criteria appli
30、cable to the plant.5.2.5 Step 5: Review the reports selected in Step 4 and usingthe variable assessment criteria for Coating Application, selectthe reports that satisfy the criteria applicable to the plant.5.2.6 If, at the completion of Step 5, there are no acceptableDBA test reports, then satisfact
31、ory 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 evaluationmay be required prior to full
