    Significance and Use

    There are several methods for managing non-conforming coatings in an operating nuclear power plant. This guide outlines methods that have been determined to be acceptable to the nuclear industry.

    Managing the amount of non-conforming coatings is key to ensuring the amount assumed, in the licensing bases is not exceeded.

    EPRI Report 1003102 Revision 1 (formerly TR-109937) provides additional information on the selection, application, inspection and maintenance of nuclear plant safety-related protective coatings. This reference offers a detailed discrussion of inportant considerations related to protective coatings and can be used to supplement this guide as deemed necessary.

    1. Scope

    1.1 This guide provides the user with guidance on developing a program for managing non-conforming coatings in Coating Service Level I areas of a nuclear power plant.

    1.2 Non-conforming coatings include degraded previously DBA-qualified or acceptable coatings, unqualified coatings, unknown coatings, and unacceptable coatings.

    1.3 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.
