This guide addresses the concerns of Regulation Guide 1.54 and USNRC Standard Review Plan 6.1.2, and the replacement of ANSI Standards N5.12, N101.2, and N101.4. This guide covers coating work on previously coated surfaces as well as bare substrates. This guide applies to all coating work in Coating Service Level I and III areas (that is, safety-related coating work). Applicable sections of this guide may also be used to evaluate and select protective coatings for Coating Service Level II areas where deemed appropriate by the licensee.
The testing referenced in this guide is particularly appropriate for safety-related coatings inside the reactor-containment. Other test methods may be used for assessing the suitability for service of safety-related coatings outside the reactor-containment. Criteria for qualification and performance monitoring of Coating Service Level III coatings shall be addressed in job specifications. Guidance for selecting and performance monitoring of Coating Service Level III coatings is provided Guides D 7230
Users of this guide must ensure that coatings work complies not only with this guide, but also with the licensee''s plant-specific quality assurance program and licensing commitments.
Safety-Related Coatings:
The qualification of coatings for Coating Service Levels I and III are different even though they are both safety-related. This guide provides the minimum requirements for qualifying Coating Service Level I coatings and also provides guidance for additional qualification tests that may be used to evaluate Coating Service Level I coatings. This guide also provides guidance concerning selection of Coating Service Level III coatings.
Coating Service Level I Coatings:
All Coating Service Level I coatings must be resistant to the effects of radiation and must be DBA qualified. The test specimens shall be prepared, irradiated and DBA tested and evaluated in accordance with the requirements of:
(a) Test Method D 3911 (b) Test Method D 4082 (c) Specification D 5139 In addition to the requirements of 4.4.2.1, Coating Service Level I coatings may be evaluated for additional qualities or may require application controls when deemed applicable by the job specifications or licensing commitments. The following documents provide guidance for application, possible additional testing or for the further evaluation of Coating Service Level I coatings when applicable: (a) Test Method C 177 (b) Practice D 3843 (c) Test Method D 3912 (d) Test Method D 4060 (e) Practice D 4227 (f) Practice D 4228 (g) Guide D 4537 (h) Test Method D 4541 (i) Test Method E 84 (j) Test Method E 1461 (k) Test Method E 1530 Condition assessment and management of Coating Service Level I coatings is also required by the licensee to maintain the co......
