Purpose and Scope. The purpose of this standard is to provide a common basis on which protective coatings (paints) for the surfaces of light water-moderated nuclear reactor containment facilities may be compared and selected by reproducible evaluation tests. Under the environmental conditions of nuclear reactor containment facilities, encompassing thermal Pressurized Water Reactors (PWR's) and Boiling Water Re-actors (BWR's), coating may deteriorate by exposure to nay one, all, or a combination of, the following conditions: ionizing radiation, contamination by radioactive nuclides and sub-sequent decontamination processes, chemical and water sprays, high-temperature, high-pressure steam, and abrasion or wear.

This standard specifically applies to the interior surfaces of the containment for PWR's and of the primary containment for BWR's and to all equipment contained therein. The standard covers coating applied to only the following materials: carbon steel, stainless steel, zinc-coated (galvanized) steel, aluminum, concrete, and masonry.

It is intended that this standard be incorporated in specifications, by reference, on the basis of user requirements.
