TS 3597

TS 3597 is a terminology standard that brings together definitions of terms used in nuclear energy. It supports a common and unambiguous vocabulary for nuclear science and the related industry, helping technical communication, documentation, and translation work use the same concepts consistently. The equivalent source is ISO 921:1972, and this edition has been withdrawn.

What nuclear energy terminology covers

Nuclear energy terminology spans concepts linked to atomic nuclei, reactor technology, the fuel cycle, radiation-related fundamentals, and the language used in measurement and plant operation. A glossary standard is about clarifying meaning, not prescribing equipment requirements or test procedures. In that sense, it serves as a reference that helps engineers, researchers, and technical writers apply the same terms in a consistent way.

Why a glossary standard matters

In a highly specialized field such as nuclear energy, small differences in wording can lead to real technical confusion. Terms such as nucleus, isotope, fission, activity, dose, and shielding may appear in similar contexts but carry distinct meanings. By organizing names and definitions, a glossary standard improves consistency in reports, training materials, equipment documentation, and technical specifications.

• Collects definitions for core concepts used in nuclear energy science.
• Promotes shared terminology across the related industry.
• Reduces ambiguity in engineering and technical communication.
• Supports consistent usage in translation and documentation.
