This collection of abbreviations in common use in the nuclear industry and regulatory community wascompiled from Nuclear Regulatory Commission (NRC) and nuclear industry sources. It was published toassist agency authors, readers, and stakeholders in identifying abbreviations for the numerous organiza-tional, scientific, and engineering terms that appear in NRC printed and electronic information. Thecompilation is descriptive rather than prescriptive. No one abbreviation is recommended to the exclusionof another because the same abbreviation may with equal validity apply to two or more terms.

The U.S. Nuclear Regulatory Commission (NRC) publishes this collection of abbreviations to assistagency authors and readers and members of the public in identifying the abbreviations for the numerousorganizational; scientific, and engineering terms that appear in NRC printed and electronic information.This collection has been compiled from NRC and nuclear industry sources and is descriptive rather thanprescriptive. No one abbreviation is recommended to the exclusion of another because the sameabbreviation may with equal validity apply to two or more terms.

An abbreviation is a shortened, condensed form of a word or term. Some technical abbreviations, suchas laser and scuba, have been so widely disseminated that they now communicate successfully withoutfurther definition. ,

Acronyms and initialisms are types of abbreviations.,

* An acronym is an abbreviation that forms a pronounceable term from the initial letters of a groupof words: ANSI is formed from American National Standards Institute and LOCA fromloss-of-coolant accident.

* An initialism is an abbreviation formed from the initial letters of a group of words for which eachletter is pronounced separately: EPZ is formed from emergency planning zone and SGTS fromstandby gas treatment system.

The NRC editorial staff offers the following suggestions for using abbreviations:

* Spell out the term for an abbreviation the first time you use it in text and follow the spelled-outterm with the abbreviation in parentheses: control rod drive (CRD). Repeat this process at thebeginning of each new section or chapter for printed publications.

* Restrict an abbreviation to one meaning in any one document. If you designate NDT to meannondestructive testing, do not designate NDT to mean nil ductility temperature or any other termbeginning with the letters NDT in the same document. Spell out any other term that could beabbreviated as NDT in that document.

This compilation includes major NRC program and staff offices, advisory groups, panels, and boards butnot NRC divisions, branches, and sections, which can be found in the NRC Telephone Directory(NUREG/BR-0046). Some abbreviations for organizations that no longer exist are included as historicalreferences.

This compilation does not include chemical elements, computer codes, and most units of measurement.Many of these abbreviations appear in readily accessible sources such as dictionaries, the GovernmentPrinting Office (GPO) Style Manual, and other manuals.

Identical abbreviations appear in various forms (e.g., AA or A/A); they are listed in this compilation inthe following order: AA, aa, A/A, A-A, A&A.

In general, the editorial staff observes the following rules for forming plurals and for capitalizing andhyphenating abbreviations: - ( . .. .

VI

*SD S 1:'

* Plurals

To form most plurals, add a lowercase s without an apostrophe preceding it to the abbreviation.

DBAs for design-basis accidentsPWRs for pressurized-water reactors

However, some abbreviations are identical in both singular and plural constructions.

ATWS for anticipated transient or transients without scramGDC for general design criterion or criteriaLCO for limiting condition or conditions for operationMOU for memorandum or memoranda of understanding

Use the same abbreviation for a'plural construction 'when a word in a term is an irregular plural(e.g., LRB for licensing review basis or bases) or when any word in a term except the last word isa regular plural, that is, formed by adding s (e.g., COLSS for core operating limit or limits support

- system). Only the irregular plurals, such as bases, are given in this collection; plurals formed byadding s to an internal or final word of a term are generally not given.

* Capitalization

Although most abbreviated terms are lowercase when written out, most of their abbreviations areuppercase.

Do not capitalize specific parts of a nuclear system or facility, the many job titles at a nuclearfacility, or generic terms designating equipment, systems, or programs.

ACCWS for auxiliary component cooling water systemRPM for radiation protection manager

However, capitalize the names of specific facilities or reactors, companies or organizations,and committees or special interest groups.

ACNW for Advisory Committee on Nuclear WasteRRA for Radiation Research Associates, Inc.RRR for Raleigh Research Reactor

* Hyphenation

To hyphenate a term from which an abbreviation is formed, follow the general rules ofhyphenation, particularly those given in the GPO Style Manual.

Hyphenate unit modifiers used as adjectives and adverbs before a noun in each term:

LOCA for loss-of-coolant accident, but not LOOP for loss of offsite power

vi

I

Do not hyphenate most short prefixes, such as co, de, pre, pro, and re.

DWCS for defueling water cleanup systemPTP for preoperational test program

1. ABSTRACT (200 words or les)

This collection of abbreviations in common use in the nuclear industry and regulatory community was compiledfrom Nuclear Regulatory Commission (NRC) and nuclear industry sources. It was published to assist agencyauthors, readers, and stakeholders in identifying abbreviations for the numerous organizational, scientific, andengineering terms that appear in NRC printed and electronic information. The compilation is descriptive ratherthan prescriptive. No one abbreviation is recommended to the exclusion of another because the same abbreviationmay with equal validity apply to two or more terms.
