l' ABSTRACT This Handbook records in_ alphabetical order abbreviations (acronyms, initial-isms, and other condensed forms) that have been used in the nuclear _ industry, both foreign and domestic.
The present volume, compiled by the editorial staff of the Division of Technical Information and Document Control, contains abbreviations used in NRC staff and contractor reports. -This. issue, although not all inclusive, is to be treated as_a compilation of available information.

[i PREFACE-
~ HOW TO USE THIS HANDBOOKu LThis Handbook._ records in alphabetical order abbreviations (acronyms, initial-isms, and other condensed forms) that have been used in the nuclear-industry.
For convenience, printed thumbLtabs indicate the location of each alphabetical ~
grouping.
GUIDE TO THE USE OF ABBREVIATIONS
-The multitude of disciplines represented in-the nuclear industry contribute heavily to the polyglot of abbreviations found throughout associated documen-tation.
Each discipline uses its own words and produces abbreviations that may j
be similar to abbreviations from another discipline that are compiled from i
' completely different words.
For example,Lan. individual referring to CTR could'
{
be discussing either a " certified test result" or a " controlled. thermonuclear j
reactor." The critical point for any writer to remember is to. spell out the complete set of words and to place the abbreviation associated with.the set of f
words immediately following, then use-it consistently.~
If a document is long and the term does not recur until much later, the term should be redefined as a 4
courtesy to the reader.
)
Definitions Abbreviation--a shortened, condensed form of a word or group of words.
Some technical abbreviations have been so widely disseminated that they now communi-4 cate successfully without further definition (for example, the words laser and scuba).
l Acronym--a pronounceable term from the initial letters of a compound expression:
ANSI is formed from American National Standards institute and LOCA from loss-
)
i of-coolant accident.
Initialism--a nonpronounceable term from the initial letters of a compound expression:
EPZ from emergency glanning zone and SGTS from standby gas treatment system.
4 Arrangement The abbreviations in this Handbook are arranged in alphabetical order.
Prepo-sitions and articles are ignored in the alphabetization (P&ID is placed as if.
i' it were PID) as are punctuation marks (M/A or A-E).
When two or more abbrevi-ations are identical, the arrangement of the spelled-out' form determines its i
. placement.

Included Abbreviations In addition to nuclear-related terms and expressions, this Handbook includes i
most of the U.S. nuclear facilities that are cancelled, delayed, completed, operating, and decommissioned.
Although it includes most nuclear vendors and architect-engineers, the list of companies,is not exhaustive.
This reflects information available to the compilers on a random basis rather than infor-mation compiled from extensive research to include all companies that touch the nuclear industry.
I Excluded Abbreviations j
Abbreviations readily found elsewhere have been excluded from this listing.
Thus, chemical symbols for the elements and for common substances, units of measurement, and computer code names are excluded.
Organizations below the level of major program and staff offices and advisory groups within NRC are not included.
Formation of Plurals Each abbreviation is given in the singular form.
For example, PWR, the abbre-viation for pressurized-water reactor, can be made a plural form by adding an "s" (PWRs).
No apostrophe should precede the addition.
Sometimes the writer.
will prefer to use a singular form (ESF, engineered safety feature) as a plural (ESF, engineered safety features), and if the writer is consistent, the reader i
will not be confused.
Singular and plural forms of words such as criterion /
criteria or memorandum / memoranda are the same.
For example, the form GDC refers to either general design criterion or general design criteria, depending on the specific in-text reference.
Capitalization Spelled out forms of the abbreviations in this Handbook are not capitalized unless they fall into the following categories:
specific facility or reactor name, companies or organizations, and committees or special interest groups.
All other words in technical documents should be treated individually as in a l
dictionary.
Specific parts of a nuclear system or facility need not be capitalized.
I NEW ENTRIES A lined space is provided at the bottom of each page for the insertion of new i
abbreviations and their meaning, if found elsewhere.
These new entries may be forwarded to the Policy and Publications Management Branch, Mail Stop W-501, l
U.S. Nuclear Regulatory Commission, Washington, D.C.
20555, for consideration and inclusion in a future revision.

l' ABSTRACT This Handbook records in_ alphabetical order abbreviations (acronyms, initial-isms, and other condensed forms) that have been used in the nuclear _ industry, both foreign and domestic.

The present volume, compiled by the editorial staff of the Division of Technical Information and Document Control, contains abbreviations used in NRC staff and contractor reports. -This. issue, although not all inclusive, is to be treated as_a compilation of available information.

l HANDBOOK 0F ACRONYMS tit

[i PREFACE-

~ HOW TO USE THIS HANDBOOKu LThis Handbook._ records in alphabetical order abbreviations (acronyms, initial-isms, and other condensed forms) that have been used in the nuclear-industry.

For convenience, printed thumbLtabs indicate the location of each alphabetical ~

grouping.

GUIDE TO THE USE OF ABBREVIATIONS

-The multitude of disciplines represented in-the nuclear industry contribute heavily to the polyglot of abbreviations found throughout associated documen-tation.

Each discipline uses its own words and produces abbreviations that may j

be similar to abbreviations from another discipline that are compiled from i

' completely different words.

For example,Lan. individual referring to CTR could'

{

be discussing either a " certified test result" or a " controlled. thermonuclear j

reactor." The critical point for any writer to remember is to. spell out the complete set of words and to place the abbreviation associated with.the set of f

words immediately following, then use-it consistently.~

If a document is long and the term does not recur until much later, the term should be redefined as a 4

courtesy to the reader.

)

Definitions Abbreviation--a shortened, condensed form of a word or group of words.

Some technical abbreviations have been so widely disseminated that they now communi-4 cate successfully without further definition (for example, the words laser and scuba).

l Acronym--a pronounceable term from the initial letters of a compound expression:

ANSI is formed from American National Standards institute and LOCA from loss-

)

i of-coolant accident.

Initialism--a nonpronounceable term from the initial letters of a compound expression:

EPZ from emergency glanning zone and SGTS from standby gas treatment system.

4 Arrangement The abbreviations in this Handbook are arranged in alphabetical order.

Prepo-sitions and articles are ignored in the alphabetization (P&ID is placed as if.

i' it were PID) as are punctuation marks (M/A or A-E).

When two or more abbrevi-ations are identical, the arrangement of the spelled-out' form determines its i

. placement.

Included Abbreviations In addition to nuclear-related terms and expressions, this Handbook includes i

most of the U.S. nuclear facilities that are cancelled, delayed, completed, operating, and decommissioned.

Although it includes most nuclear vendors and architect-engineers, the list of companies,is not exhaustive.

This reflects information available to the compilers on a random basis rather than infor-mation compiled from extensive research to include all companies that touch the nuclear industry.

I Excluded Abbreviations j

Abbreviations readily found elsewhere have been excluded from this listing.

Thus, chemical symbols for the elements and for common substances, units of measurement, and computer code names are excluded.

Organizations below the level of major program and staff offices and advisory groups within NRC are not included.

Formation of Plurals Each abbreviation is given in the singular form.

For example, PWR, the abbre-viation for pressurized-water reactor, can be made a plural form by adding an "s" (PWRs).

No apostrophe should precede the addition.

Sometimes the writer.

will prefer to use a singular form (ESF, engineered safety feature) as a plural (ESF, engineered safety features), and if the writer is consistent, the reader i

will not be confused.

Singular and plural forms of words such as criterion /

criteria or memorandum / memoranda are the same.

For example, the form GDC refers to either general design criterion or general design criteria, depending on the specific in-text reference.

Capitalization Spelled out forms of the abbreviations in this Handbook are not capitalized unless they fall into the following categories:

specific facility or reactor name, companies or organizations, and committees or special interest groups.

All other words in technical documents should be treated individually as in a l

dictionary.

Specific parts of a nuclear system or facility need not be capitalized.

I NEW ENTRIES A lined space is provided at the bottom of each page for the insertion of new i

abbreviations and their meaning, if found elsewhere.

These new entries may be forwarded to the Policy and Publications Management Branch, Mail Stop W-501, l

U.S. Nuclear Regulatory Commission, Washington, D.C.

20555, for consideration and inclusion in a future revision.
