Standard Guide for Use of Protective Coating Standards in Nuclear Power Plants
1.1 This guide provides a common basis on which protective coatings for the surfaces of light water-moderated nuclear power generating facilities may be qualified and selected by reproducible evaluation tests. This standard 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 (PWR's) and Boiling Water Reactors (BWR's), 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.
1.2 The content of this guide includes:
1.2.1 In addition, this guide addresses technical topics within ANSI N5.12 and ANSI N101.2 that were covered by separate ASTM standards, for example, surface preparation, shop and field and coating application, and shop and field.
1.2.2 Applicable sections of this guide and specific acceptance criteria may be incorporated into specifications and other documents where appropriate.
1.3 This standard does not purport to address all of the safetyconcerns, 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.
