1. Scope
1.1 This guide provides a common basis on which protec- tive coatings for the surfaces of nuclear power generating facilities may be qualified and selected by reproducible evalu- ation tests. This guide also provides guidance for application and maintenance of protective coatings. Under the environ- mental operating and accident conditions of nuclear power generation facilities, encompassing pressurized water reactors (PWRs) and boiling water reactors (BWRs), coating perfor- mance may be affected by exposure to any one, all, or a combination of the following conditions: ionizing radiation; contamination by radioactive nuclides and subsequent decon- tamination processes; chemical and water sprays; high- temperature high-pressure steam; and abrasion or wear.1.2.1 In addition, this guide addresses technical topics within ANSI N5.12 and ANSI N101.2 that are covered by separate ASTM standards, for example, surface preparation, (shop and field) and coating application, (shop and field). 1.2.2 Applicable sections of this guide and specific accep- tance criteria may be incorporated into specifications and other documents where appropriate. 2 1.3 The values stated in inch-pound units are to be regarded as standard. No other units ofmeasurement are included in this standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appro- priate safety, health, and environmental practices and deter- mine the applicability ofregulatory limitations prior to use. 1.5 This international standard was developed in accor- dance with internationally recognized principles on standard- ization established in the Decision on Principles for the Development of International Standards, Guides and Recom- mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
4. 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 replace- ment 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 D7230 and D7167 respectively, and Sec- tions 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 com- mitments. 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 ofCoating Service Level III coatings. Coating Service Level III coatings must be evalu- ated 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 D4541, (b) Guide D7167, (c) Guide D7230, (d) EPRI 1019157 (formerly TR-109937 and 1003102), Sections 4.4 and 4.5, (e) 10CFR50.65, and (f) 10CFR50.
