ASTM C859-24 PDF

Overview

ASTM C859-24: Standard Terminology Relating to Nuclear Materials is an international standard developed by ASTM Committee C26 on Nuclear Fuel Cycle. This terminology standard provides authoritative definitions, nomenclature, acronyms, and symbols pertinent to nuclear materials, supporting consistency and clarity across technical documents and standards related to the nuclear fuel cycle. The standard plays a vital role in facilitating communication and interpretation among professionals working with nuclear fuel, radioactive waste management, and associated analytical methods.

Key Topics

ASTM C859-24 encompasses terminology for a wide array of concepts vital in nuclear materials science and technology, including:

• Nuclear Fuel Cycle: Definitions relevant to various stages such as fuel fabrication, irradiation, reprocessing, and waste disposal.
• Radiation and Radioactivity: Terms for types of radiation (alpha, beta, gamma, neutron), units of measurement (becquerel, gray, sievert), and biological effects.
• Analytical Methods: Standardized vocabulary for physical and chemical analysis, such as destructive analysis (DA), non-destructive assay (NDA), and calibration procedures.
• Materials and Waste Forms: Nomenclature for spent nuclear fuel types (e.g., aluminum-based spent fuel), waste forms, corrosion products, and high-level radioactive waste.
• Test Methods and Quality Assurance: Descriptions of leach tests, calibration and verification solutions, and concepts supporting measurement reliability.
• Facilities and Equipment: Definitions of facilities like hot cells, dry cask storage systems, canyons, and remote handling devices such as electro-mechanical manipulators.

Additionally, the standard offers explanations for commonly used acronyms and abbreviations, ensuring clarity in technical communication.

Applications

ASTM C859-24 is an essential reference for:

• Standards Development and Compliance: Assisting committees, developers, and regulators in harmonizing language used in nuclear fuel cycle standards and technical documents.
• Nuclear Industry Operations: Supporting nuclear fuel fabrication, handling, assay, and waste management by providing precise terminology, reducing ambiguity in procedures and reporting.
• Regulatory Documents and Reports: Useful in drafting, reviewing, and interpreting regulatory or safety documentation where accurate definitions are critical.
• Research and Education: Serving as a foundation for educational materials and research publications in nuclear engineering, radiology, and environmental sciences.
• International Collaboration: Improving understanding and collaboration across borders by standardizing terminology, especially for organizations referencing ASTM standards globally.

The standard’s flexible approach allows subcommittees to propose and include new terms as the profession evolves, ensuring relevance and comprehensive coverage.

Related Standards

For comprehensive application and understanding, ASTM C859-24 should be considered alongside other related ASTM standards and technical guides, such as:
