REGULATORY GUIDE 1.54 QUALITY ASSURANCE REQUIREMENTS FOR PROTECTIVE COATINGS

APPLIED TO WATER-COOLED NUCLEAR POWER PLANTS

A. INTRODUCTION

Coatings Applied to Nuclear Facilities,"' for protective coatings applied to ferritic steels, aluminum, stainless Appendix B to 10 CFR Part 50, "Quality Assurance steel, zinc-coated (galvanized) steel, concrete, or masonry Criteria for Nuclear Power Plants and Fuel Reprocessing surfaces of water-cooled nuclear power plants are Plants," establishes overall quality assurance program generally acceptable and provide an adequate basis for requirements for the design, fabrication, construction, complying with the pertinent quality assurance and operation of safety-related nuclear power plant requirements of Appendix B to 10 CFR Part 50 subject structures, systems, and components. This guide to the following:

describes an acceptable method of complying with the Commission's quality assurance requirements with 1. ANSI N101.4-1972 should be used in conjunction regard to protective coatings applied to ferritic steels, with ANSI N45.2-1971, "Quality Assurance Program aluminum, stainless steel, zinc-coated (galvanized) steel, Requirements for Nuclear Power Plants." 2 concrete, or 'Masonry surfaces of water-cooled nuclear power plants. The Advisory Committee on Reactor 2. Subdivision 2.7 of ANSI N101.4-1972 states that Safeguards has been consulted concerning this guide and when references are made to other standards, these has concurred in the regulatory position. references shall imply the most recent or current editions of the referenced standard

B. DISCUSSION

applicability or acceptability of referenced standards will be covered separately in other regulatory guides, where Subcommittee N101.5.7 of the American National appropriate.

Standards Institute (ANSI) Standards Committee NIO1, Atomic Industry Facility Design, Construction, and 3. Subdivision 1.1.2 of ANSI N101.4-1972 states that Operation Criteria, under the sponsorship of the quality assurance, as covered by this standard, comprises American Institute of Chemical-Engineers, has developed all those planned and systematic actions necessary to a standard which includes quality assurance provide specified documentation and adequate requirements for protective coatings applied to ferritic confidence that shop or field coating work for nuclear steels, aluminum, stainless steel, zinc-coated (galvanized) facilities will perform satisfactorily in service. This steel, concrete, or masonry surfaces of nuclear facilities. statement should not be interpreted as implying that the This standard was approved by the American National end product of quality assurance actions is the Standards Committee N1O0 and its Secretariat. It was production of specified documentation. The term subsequently approved and designated N101.4-1972 by the American National Standards Institute on November 28, 1972.

"quality assurance" as used in ANSI N1OI.4-1972 materials used with stainless steel should not be should be considered to comprise all those planned and compounded from or treated with chemical compounds systematic actions necessary to provide adequate containing elements that could contribute to corrosion, confidence that shop or field coating work for nuclear intergranular cracking, or stress corrosion cracking.

In this Examples of such chemical compounds are those connection it is emphasized that records and documents containing chlorides, fluorides, lead, zinc, copper, sulfur, listed in Subdivisions 7.4 through 7.8, and included in or mercury where such elements are leachable or where the standard, are suggested forms only. Alternate they could be released by breakdown of the chemical documentation consistent with the requirements of compounds under expected environmental conditions Appendix B to 10 CFR Part 50 is also considered (e.g., by radiation). This limitation is not intended to acceptable. prohibit the use of trichlorotrifluoroethane which meets the requirements of Military Specification

4. Sections 3 and 4 of ANSI N101.4-1972 delineate MiL-C-81302b for cleaning or degreasing of austenitic quality assurance requirements for coating materials and stainless steel provided adequate removal is assured prior surface preparation of substrates. Coatings and, cleaning to painting.
