degradation would adversely impact post-accident safety systems. b. Licensees should perform condition assessments under the direction of a nuclear coating specialist, as defined in ASTM D 7108-12. c. Licensees should evaluate degraded coatings identified during condition assessments for their effect on the ECCS post-accident function consistent with the guidance in RG 1.82 “Water Sources for Long-Term Recirculation Cooling following a Loss-Of-Coolant Accident,” (Ref. 29) and in accordance with applicable licensing-basis documents. d. Although the ASTM D 5163-08 standard reasonably ensures that qualified coatings left in service after a visual inspection will remain adhered to their substrates under accident conditions, it does not guarantee that visual inspection will detect all degraded coatings. Therefore, the licensee or applicant should include a safety margin in their debris- generation calculations for the ECCS strainer performance that allows for an additional quantity of debris from failed coatings or perform a debris transport analysis showing that the debris will not reach the ECCS strainer. 4.2 ASTM D 7167-12, “Standard Guide for Establishing Procedures to Monitor the Performance of Safety-Related Coatings Service Level III Lining Systems in an Operating Nuclear Power Plant,” (Ref. 30) provides guidelines that the NRC staff finds acceptable for establishing procedures to monitor the performance of Service Level III lining systems in an operating NPP. 4.3 ASTM D 3359-09ε2, “Standard Test Methods for Measuring Adhesion by Tape Test,” (Ref. 31) offers guidance that the NRC staff finds acceptable for assessing the adhesion of coating films to metallic substrates by using pressure-sensitive tape. 4.4 ASTM D 4541-09ε1, “Standard Test Method for Pull-Off Strength of Coatings Using Portable Adhesion Testers,” (Ref. 32) provides guidance that the NRC staff finds acceptable for a test method used to evaluate the pull-off strength of coatings on
