ASTM D5144-08 (2021) PDF

Full title and description

Standard Guide for Use of Protective Coating Standards in Nuclear Power Plants — ASTM D5144-08 (reapproved 2021). Provides guidance for qualifying, selecting, applying, inspecting, and maintaining protective coatings used in nuclear power generating facilities, with emphasis on safety-related coatings and coatings subject to ionizing radiation, decontamination, high-temperature/pressure steam and abrasion.

Abstract

This guide establishes a common basis for reproducible evaluation tests, qualification criteria, and job‑specification guidance for protective coatings used in PWR and BWR nuclear plant applications. It differentiates requirements for Coating Service Levels I, II and III (with special qualification and DBA/radiation resistance requirements for Level I), and references relevant ASTM test methods, EPRI guidance and NRC regulatory considerations.

Scope

The guide provides a common basis for qualifying and selecting protective coatings for nuclear power plant surfaces, including testing and acceptance criteria for coatings exposed to ionizing radiation, contamination and decontamination, chemical/water sprays, high-temperature/high-pressure steam, and mechanical wear. It applies principally to safety‑related coatings (Coating Service Levels I and III) and may be used for Level II where appropriate; it also provides guidance on surface preparation, application, inspection and quality assurance for shop and field work.

Key topics and requirements

• Definition and differentiation of Coating Service Levels I, II and III (safety-related distinctions and application areas).
• Mandatory radiation resistance and design‑basis-accident (DBA) qualification requirements for Coating Service Level I coatings (irradiation and post‑irradiation testing).
• Referenced test methods and specifications for qualification and performance monitoring (examples: Test Methods D3911, D4082, D4541; Specification D5139; Guides D7167, D7230, D5163).
• Guidance on surface preparation, coating application, inspection, and quality assurance for both shop and field work.
• Consideration of plant licensing commitments and NRC regulatory guides in specifying and approving coatings for nuclear service.

Typical use and users

Used by nuclear utility engineers, coating/materials engineers, plant QA/QC personnel, licensing engineers, coating manufacturers, and contractors performing coating work in nuclear facilities. Typical applications include containment interiors, radiation‑controlled areas, service water systems, heat‑exchanger internals, and other safety‑related or safety‑adjacent surfaces requiring validated performance under radiation and accident conditions.
