Significance and Use
4.1 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.
4.2 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 and respectively, and Sections 4.4 and 4.5 of EPRI 1019157 (formerly TR-109937 and 1003102.).
4.3 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.
4.4 Safety-Related Coatings:
4.4.1 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.
4.4.2 Coating Service Level I Coatings:
126.96.36.199 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 Methodor plant specific requirements as applicable,
(b) Test Method, and
188.8.131.52 In addition to the requirements of , 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) Test Method,
(d) Test Method,
(h) Test Method,
(i) Test Method,
(j) Test Method,
(k) Test Method, and
(l) Test Method.
184.108.40.206 Condition assessment and management of Coating Service Level I coatings is also required by the licensee to maintain the coatings following the initial application and subsequent repairs. The following documents provide guidance for the monitoring and management of the Coating Service Level I coatings:
4.4.3 Coating Service Level III Coatings:
220.127.116.11 Coating Service Level III coatings must be evaluated for use in accordance with the requirements of plant licensing commitments and the job specifications. Coating Service Level III coatings may include linings used in areas such as service water systems, essential cooling water heat exchanger heads and emergency diesel generator air intakes. There are no specific testing or qualification requirements included in this guide for Coating Service Level III coatings or linings. Testing and evaluation of Coating Service Level III coatings should be conducted as necessary to ensure that the coatings are suitable for the specific service environment. The following documents provide guidance for testing and inspection, which the licensee may consider when preparing job specifications for Coating Service Level III coatings or linings:
(a) Test Method,
(d) EPRI 1019157 (formerly TR-109937 and 1003102), Sections 4.4 and 4.5,
(e) 10CFR50.65, and
(f) 10CFR50. Appendix B.
4.5 Coatings Service Level II Coatings:
4.5.1 Coating Service Level II coatings are not safety-related and are restricted to the radiation controlled area (RCA) outside of the reactor-containment in nuclear power plants. There are no specific testing or qualification requirements included in this guide for Coating Service Level II coatings. The following documents provide guidance for testing and inspection, which the licensee may consider when evaluating or specifying Coating Service Level II coatings:
(a) Test Method,
(b) Test Method,
(c) Test Method,
(d) Test Method,
(f) Test Method,
(g) Test Method, and
(h) USNRC Regulatory Guide 8.8.
4.5.2 Some nuclear power plant licenses may include requirements for Coating Service Level II coatings; these requirements must be satisfied when selecting Coating Service Level II coating materials and systems.
1.1 This guide provides a common basis on which protective coatings for the surfaces of nuclear power generating facilities may be qualified and selected by reproducible evaluation tests. This guide also provides guidance for application and maintenance of protective coatings. Under the environmental operating and accident conditions of nuclear power generation facilities, encompassing pressurized water reactors (PWRs) and boiling water reactors (BWRs), coating performance may be affected by exposure to any one, all, or a combination of the following conditions: ionizing radiation; contamination by radioactive nuclides and subsequent decontamination processes; chemical and water sprays; high-temperature high-pressure steam; and abrasion or wear.
