REVIEW OF 'NRC'S COLLECTION OF ABBREVIATIONS
- My staff has compiled Revision 4 to 'NRC's Collection of Abbreviations"(NUREG-0544), which-was last revised in March 1992 (Attachment). Abbreviations collected since then were added to the existing compilation, increasing its volume by about 17 pages. This revision includes a new introduction that presents NRC's preferred editorial style for use of abbreviations in NRC.
documents. After reviewing office comments, the collection will be published and posted to the NRC Web site.
I would appreciate receiving your comments and concurrence by September 30,1997.

INTRODUCTION The U.S. Nuclear Regulatory Commission (NRC) publishes this collection of abbreviations to assist agency authors and readers and members of the public in identifying the abbreviations for the numerous organizational, scientific, and engineering expressions that appear in NRC print and electronic information. This collection has been compiled from NRC and nuclear industry sources and is descriptive rather than i prescriptive. No one abbreviation is recommended to the j exclusion of another because the same abbreviation may with equal validity apply to two or more expressions.
An abbreviation is a shortened, condensed form of a word or expression. Some technical abbreviations, such as laser and scuba, have been so widely disseminated that they now communicate successfully without further definition.
Acronyms and initialisms are types of abbreviations.
. An acronym is a pronounceable abbreviation formed from the initial letters of a group of words: ANSI is formed from 4 American National Standards Institute and LOCA from loss-of-coolant accident.
- An Initialism is a nonpronounceable abbreviation formed from the initial letters of a group of words: EPZ is formed from emergency planning zone and SGTS from standby gas treatment system.
The NRC editorial staff offers the fallowing suggestions for using abbreviations:
- Spell out the term for an abbreviation the first time you use it in text and follow the spelled-out term with the abbreviation in parentheses: control rod drive (CRD).
Repeat this process at the beginning of each new section or chapter for printed publications.
. Restrict an abbreviation to one meaning in any one document. If you designate NDT to mean nondestructive testing, do not designate NDT to mean nil ductility temperature or any other term beginning with the letters 1 NUREG-0544, Rev.4
l INTRODUCTION l
l l
NDT in the same document. Spell out any other term that could be abbreviated as NDT in that document.
This compilation includes major NRC program and staff offices, advisory groups, panels, and boards but not 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 historical references.
This compilation does not include chemical elements, computer codes, and most units of measurement. Many of these at:-reviations appear in readily accessible sources such as dictionaries, the Govemment Printing Office (GPO) Style Manual, and other manuals.
Identical abbreviatians appear in various forms (e.g., AA or A/A); they are listed in this compilation in the 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 and hyphenating abbreviations: I e Plurals i
To form most plurals, add a lowercase s without an apestrophe preceding it to the abbreviation.
DBAs for design-basis accidents PWRs for pressurized-water reactors However, some abbreviations are identical in both singular and plural constructions.
ATWS for anticipated transient or transients without scram GDC for general design criterion or criteria LCO for limiting condition or conditions for operation MOU for memorandum or memoranda of understanding Use the same abbreviation for a plural construction when a l word in a term is an irregular plural (e.g., LRB for licensing l NUREG-0544. Rev. 4 2
)
i INTRODUCTION l l
l l
review basis or bases) or when any word in a term except the last word is a regular plural, that is, formed by adding s (e.g., !
COLSS for core operating limit or limits support system). Only 1
the irregular plurals, such as basis or bases, are given in this collection; plurals formed by adding s to an internal or final word of a term are not given.
e Capitalization Although most abbreviated terms are lowercase when written out, most of their abbreviations are uppercase.
Do not capitalize specific parts of a nuclear system or facility, the many job titles at a nuclear facility, and generic terms designating equipment, systems, or programs.
ACCWS for auxiliary component cooling water system RPM 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 Waste RRA 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 of hyphenation, 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 3 NUREG-0544, Rev. 4
INTRODUCTION Do not hyphenate most short prefixes, such as co, de, pre, pro, and re.
DWCS for defueling water cleanup system PTP for preoperational test program The NRC welcomes new entries for future revisions of this collection.
