Significance and Use
4.1 For conformance with the intent of the criteria listed in and , coating qualification tests are founded on plant-specific test parameters that realistically reflect or bound the material and process variables that can reasonably be expected to influence qualification testing performance.
4.2 This guide provides guidance for evaluating existing coating system qualification data for applicability to the nuclear plant desiring to use a coating system not previously used in the plant or to qualify an existing coating system.
4.3 It is recognized that new-build plants, as well as small modular reactors currently under development, may have design features that differ from those of the operating plants that formed the basis for the existing test data. Therefore, careful review is required to assure that coating performance requirements critical to the new design are adequately addressed in the existing data or the need for additional coating testing is identified.
1.1 The purpose of this guide is to identify evaluation variables that can be used to determine whether existing coating qualification test data (for example, design basis accident or DBA, chemical resistance, fire resistance, thermal conductivity, etc.) meet the respective nuclear power plant qualification requirements or whether requalification is required. Guidance on developing a coating qualification test plan/procedure to qualify a new coating is beyond the scope of this standard.
1.2 This guide is intended for use in new construction and for refurbishing existing coating systems applied to concrete and metal substrates within containment.
1.3 This guide is intended for the use by, or under the supervision of, a person knowledgeable in coating technology and coatings used in CSL I applications, such as a person meeting the requirements of Guide or equivalent.
1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.5 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 appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
