    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 organiza-

    tional, 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.

    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 comm unicate 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.

    *SD

    S

    1:'

    * 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 bases, are

    given

    in

    this

    collection; plurals formed by

    adding

    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 are

    uppercase.

    Do not capitalize specific parts of

    a

    nuclear system or facility, the

    many

    job titles at

    a

    nuclear

    facility,

    or

    generic terms

    designating equipment,

    systems,

    or

    programs.
