Standard Guide for Establishing Procedures to Monitor the Performance of Safety-Related Coating Service Level III Lining Systems in an Operating Nuclear Power PlantASTM International / 01-Jun-2005 / 5 pages

1.1 This guide covers procedures for establishing a program to monitor the performance of Coating Service Level III lining (and coating) systems in operating nuclear power plants. Monitoring is an ongoing process of evaluating the condition of the in-service lining systems.1.2 Coating Service Level III lining systems subject to this guide are generally those applied to metal substrates comprising raw water or condensate-quality water wetted (that is, full or intermittent immersion) surfaces in systems that include:1.2.1 Service water piping upstream of safety-related components,1.2.2 Service water pump internals (draft tube, volutes, and diffusers),1.2.3 Service water heat exchangers including the channels, pass partitions, tubesheets, end bells, and covers1.2.4 Service water strainers, and1.2.5 Reactor water storage tanks (RWSTs) and refuel cavity water storage tanks.1.3 It is the intent of this guide to provide a recommended basis for establishing a coatings monitoring program, not to mandate a singular basis for all programs. Variations or simplifications of the program described in this guide may be appropriate for any given operating nuclear power plant depending on its licensing commitments. Similar guidelines may be applicable for certain Coating Service Level II applications such as fluid immersion systems.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 appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
