Abstract
This collection of abbreviations in common use in the nuclear industry and
regulatory community was compiled from Nuclear Regulatory Commission (NRC) and
nuclear industry sources. It was published to assist agency authors, readers,
and stakeholders in identifying abbreviations for the numerous organizational,
scientific, and engineering terms that appear in NRC printed and electronic
information. The compilation is descriptive rather than prescriptive. No one
abbreviation is recommended to the exclusion of another because the same abbreviation
may with equal validity apply to two or more terms.
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
terms that appear in NRC printed and electronic information. This collection
has been compiled from NRC and nuclear industry sources and is descriptive rather
than prescriptive. No one abbreviation is recommended to the exclusion of another
because the same abbreviation 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, 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 an abbreviation that forms a pronounceable
term from the initial letters of a group of words: ANSI is formed from American
National Standards Institute
and LOCA from loss-of-coolant
accident.
-
An initialism is an abbreviation formed from the initial
letters of a group of words for which each letter is pronounced separately:
EPZ is formed from emergency planning
zone and SGTS from standby 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-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 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 abbreviations appear in readily accessible
sources such as dictionaries, the Government Printing 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 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:
- Plurals
To form most plurals, add a lowercase s without an apostrophe 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 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 is a 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 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.
- 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
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
