A-502.1 EMERGENCY AND ABNORMAL OPERATING PROCEDURES WRITERS GUIDE
1.0 INTRODUCTION
1.2 1.3 PURPOSE to provide technical and 'dministrative guidance on the preparation of EOPs and APs.
SCOPE OF APPLICATIONS this Nriters Guide shall be applied to the writing and revision of all EOPs and APs.

1.3.3.3 1.3.3.4 1.3.3.5 1.3.3.6 1.3.4 1.3.5 EMERGENCY OPERATING PROCEDURE (EOP) - a procedure which provides actions necessary to return the plant to a
- safe, stable condition following transient/accident:
conditions which have caused plant parameters to challenge reactor protection system set
- points, engineered safeguards system set points, challenge the ability to cool the reactor
- core, or a
radiation release boundary.
ABNORMAL OPERATXNG PROCEDURE (AP)
APs govern the plant operations during abnormal conditions and specify operator actions that will prevent the condition from degrading into an emergency.
CRITICAL SAFETY FUNCTION (CSF)
CSFs are those functions necessary to protect the fuel/cladding, RCS pressure boundary and the containment vessel from degradation.
A prioritized list of these six functions is as follows:
Maintenance of Subcriticality Maintenance of Core Cooling Maintenance of Heat Sink Maintenance of RCS Xntegrity Maintenance of Containment Integrity Control of Reactor Coolant Inventory SHALL the word SHALL denotes a requirement.
SHOULD the word SHOULD denotes a recommendation.
A-502.1:2 1.3.6 1.4 MAY the word MAY denotes permission, it denotes neither a requirement nor a recommendation.

2.2.1 EOP AP ORGANIZATION AND CONTENT each EOP/AP will normally contain the following:
COVER PAGE
which will contain the following information; EOP alpha-numeric designation and title Revision number Effective date Total number of pages in the procedure Provision for review signature Provision for approval signature Facility identification PORC review date PURPOSE AND ENTRY CONDITIONS SYMPTOMS PAGE which contains; PURPOSE STATEMENT brief statement which describes what it is intended the procedure will accomplish.
2'.2 2.3 2.3.1 A-502.1:3 ENTRY CONDITIONS/SYMPTOMS section which will include those
- alarms, indications, operating conditions, automatic actions or other unique symptoms that the operator is to consider when deciding to use the procedure.
Entry conditions may also include referenc-ing or related procedures.
OPERATOR ACTION STEPS general requirements are that action steps be structured so that they can be executed by minimum shift staffing as required by Technical Specifications, and be consistent with the responsibilities of the shift positions.
In addition, the action steps should minimize the movement of personnel in the Control Room and enable the effective supervisory overview to monitor plant status.
OPERATOR ACTION STEPS are
- short, precise statements presenting, exactly the task to be performed and the expected response or result of that task.
It nece is no St ssary to state expected results of routine task s s
~
othe eps are assumed to be performed in sequence unl rwise denoted.
Actions directed in a step should ess not be expected to be complete before the next step is begun.
If a particular action must be completed before continuation, this must be stated in that step or substep.
The action steps are presented in a
dual column format and are identified as immediate or subsequent actions.
2 ~ 3 ~ 1.1 ACTION/EXPECTED
RESPONSE
column contains sequentially ordered steps and substeps with the initial operator task and its expected response.
The ex e user would normally move down this column a
h p cted response is obtained.
When an expected response is not obtained, the user is expected to move to the right hand column for guidance.
2.3.1.2 THE
RESPONSE
NOT OBTAINED (RNO) column presents contingency actions to be taken when a stated t'
eft hand column cannot be performed or does not satisfy the expected response.
RNO column actions are specified for steps and substeps for which useful alternatives are available.
The following should be applied to the format of RNO column entrys:
2.3.1.2.1 Contingency actions should use directions to override automatic controls and to manually or locally initiate normally automatic actions.
I
A-502.1:4 2.3.1.2.2 A contingency action should be numbered or lettered the same as the left-hand column substep to which it applies.
A contingency entry for a high-level step is not
- numbered, but.
appears on the same line as its related step.
2.3.1.2.3 To describe a sequence of actions which are contingent upon plant or component conditions, a
series of conditional statements should be used.
Example:
Check PRZR PORVs CLOSED IF PRZR pressure less than (1)
- psig, THEN manually close PORVs.
IF any valve can NOT be
- closed, THEN manually close its block valve.
2.3.1.2.4 If the RNO column contains multiple contingency actions for a
single left-hand column
- action, the phrase "Perform the following:" may be used as the introductory statement.
2.3.1.2.5 If the RNO column action step contains multiple actions or substeps which do not correspond to multiple substeps in the left-hand
- column, then different designators should be used in each column.
Example:
Establish Letdown:
Establish excess letdown:

3) 2.3.1.2.6 The user is expected to proceed to the next step or substep in the left-hand column after taking the RNO column action unless instructed otherwise.
2.3.1.2.7 If the RNO column action step or substep cannot be completed, the user is expected to proceed to the next left-hand column step or substep unless instructed otherwise.
2.3.1.2.8 As a general
- rule, contingent transitions occur from the RNO column.
Deliberate transitions may be made from the left-hand column.
A-502.1:5 2.3.1.3 Immediate operator actions actions which the operator is expected to perform from memory. at the onset of an events in w
emergency condition.
These should be actions for safet or co s

SE UENCING OF OPERATOR ACTION STEPS OPERATOR ACTION STEPS should be numbered sequentially in order of expected performance.
OPERATOR ACTION SUBSTEPS should be lettered or numbered sequentially in order of expected performance.
OPERATOR ACTION SUBSTEPS should be designated by "bullets" (o) if no order of performance is expected or required.
JI EMPHASIS TECHNI UES the following techniques will be used for emphasizing certain information in the EOPs and APs:
CAPITALIZATION in addition to standard American English usage, the following should be capitalized:
The word NOTE in note statements all capitals.
The word CAUTION and all words contained in caution statements all capitals.
The 'ogic terms identified in section 5.11 all capitals.

ASTERISKS
a continuous line of asterisks shall enclose all caution statement at the top and bottom.
5.2.4 BULLETS (o) proceeding a specific operator action substep or NOTE:
5.3 VOCABULARY the following rules apply to all words used in EOPs and APs; 5.3.1 Only words which have,.the following characteristics should be used:
5.3.1.1 Simple, short words of few syllables.
5.3. 1.2 Words commonly used in training material, control room labels and reference material utilized by the operators.
Control Room label wording is preferred.
5.3.1.3 5.3.2
- Precise, specific, familiar and definite.
Operator Action Steps should begin with an action verb as listed and defined in TABLE 1.
A-502.1:14 5.3.3 Spelling should be consistent with modern usage and when a
choice is offered by a dictionary, the first choice should be used.
5.4 5.4.1 ABBREVIAT ONS AND ACRONYMS are subject to the following limitations; Abbreviations may be used where necessary to save time and space in the interest of clarity and brevity.
5.4.2 Use of an abbreviation which causes any ambiguity or confusion shall not be permitted.
5.4.3 Only those abbreviations listed in the QA Manual (Reference 1.4.5) should be used in an EOP or AP unless the abbreviation is part of an approved procedure title or Control Room label.
5.4.4 5.4.5 Abbreviations used from a
source designated in step 5.4.3 should be used
- verbatim, in terms of upper and lower case letters,
- numerals, periods and decimals.
Acronyms which are not commonly used or previously defined should not be used.
5.5 NARRATIVE STYLE steps may be written as complete sentences, short
- phrases, or some combination of the two.
Notes and cautions should be written as complete sentences.
Sentences, clauses and phrases should be short and precise utilizing normal American
.English word order where practical.
Operator action steps should:
5.5.1 5.5 '
5.5.3 5.5.4 Be short, imperative statements which state the exact task that the operator is expected to perform.
t Deal with only one idea.
Complex evolutions should be broken down into a series of steps and substeps.
Be clear as to the objectives of operator actions.
Be written in sentence form in the right-hand column.
5.6 PUNCTUATION the rules of punctuation for standard American English should be used where practical.
Word order should be selected to minimizes the amount of required punctuation.
Punctuation should be minimized to that necessary to aid reading and promote understanding.
Individual punctuation characters should be used under the following guidances.
5.6.1 5.6.2 5.6.3 A-502-1:15 PERIOD a
period shall be used at the end of all complete sentences, to indicate a
decimal l
numbers aand may be used at the end of each phrase used in an action step where a distinct separation from a following phrase or sentence is desired.
COMMA commas are used to indicate natural d'ra 1vlslons
'g pauses xn sentences.
Use of too many commas is an indication that a sentence or instruction is too complex and should be rewritten.
Commas shall be used in conditional phrases.
COLON - a colon is normally used to indicate a list is to follow.
In the EOP/AP sets it is also used after the initial action step when substeps are used.
5.6.4 5.6.5 5 ~ 6 ~ 6 5.6.7 5.6.8 HYPHEN q hyphen is used to form an adjective from two not-normally hyphenated words and when a word must be broken for continuation on. another line.
The use of hyphenated words should be minimized.
rovide DASH a
dash is used in operator action t
t p
separation between the<action portion and the s eps o
expected response portion of the step or substep.
PARENTHESES are used to provide the adverse containment values for instrumentation readings in applicable designations and instrument designators when these are noted in addition to a word descriptor.
Parentheses may such as loc also be used to provide amplifying or useful i f t'catzons, breaker cubicle designations, and ste s
information which cannot be placed in t
in a no e prior to a s ep as xt only applies to a specific substep cond't'POSTROPHE apostrophes are generally used to indicate the plural form of abbreviations or symbol A
no be used.
The plural form of any word used in the writing of EOPs and AP will be shown simply by the addition of an s or es as necessary.
QUOTATION
- MARKS, EXCLAMATION POINTS, QUESTION
- MARKS, ITALICS and BRACKETS (except as needed in 1
1 t'hould not be used.
e z.n ca cu atzons) 5.7 UNITS OF MEASURE should be stated in terms used by addressed.
Control Room indication for the parameter bein eing 5.8 NUMERALS numerical values should be consistent with the following rules:
A-502.1:16 5.8. 1 5.8.2 5.8.3 5.8.4 5.9 5.10 5.11 Arabic numerals should be used.
A decimal point should be preceded by a
zero for numbers less than unity.
The number of significant digits should be no greater than the number of significant digits on available instrumentation or the reading precision of the operator.
No less than one-half of one meter division should be used.
f Control values and limits should be stated quantitatively where necessary and may be followed by the tolerance in parentheses.
TOLERANCES tolerances should be stated in terms of upper and lower limits where possible such that addition and subtraction by the user is avoided.
Tolerances shall have the same units as the instrumentation to which they refer.
FORMULAS AND CALCULATIONS should be avoided.
Values which must be determined to perform a procedural step should utilize graphs or figures. If a calculation has to be performed, the needed
- formulas, conversion factors and space to perform the calculation shall be provided.
LOGIC TERMS AND CONDITIONAL STATEMENTS (See Appendix A for specific examples) the logic terms
- AND, OR, IF, IF
- NOT, THEN, and WHEN are often used to precisely define a set of conditions or sequence of actions.
The use of these logic terms shall follow the guidelines listed below:
5.11.1 All letters of logic terms shall be emphasized by capitalization and underlining when used in logic statements.
5.11.2 The use of AND and OR within the same action step should be avoided.
5.11.3 When combinations of conditions are used the word AND should be placed between a description of each condition for no more than a combination of three conditions.
A list format shall be used for four or more conditions.
The AND condition is assumed in a list unless otherwise specified.
~
~
A-502. 1: 17 The word OR shall be used between alternative conditions.
Use of the word OR in this manner implies he inclusive sense.
The exclusive sense of the word both.
OR is denoted by using the form; either A OR B b t t
u no Should action steps be contingent upon certain conditions with t or combinations of conditions, the step shall b
he logic terms IF or WHEN followed by a description egin of the condition(s),
a
- comma, the logic term THEN and the action to be taken.
IF is used for unexpected or possible conditions and WHEN is used for expected or probable conditions.
The use of the logic term IF NOT should be limited to cases in which the operator must respond to the second of any two possible conditions.
The term IF should be used to specify operator response to the first of any two possible conditions.
THEN should only be used in conditional statem t should not be used at the end of action steps THEN e en s.
because it tends to run operator action steps together.
BRANCHING ING branching encompasses transitioning, either to another step in the same procedure or to another EOP/AP; and referencing another procedure for supplemental information or direction.
Transitioning is a series operation while referencing is a parallel operation.
TRANSITION TO A
LATER STEP WITHIN CURRENT EOP/AP shall be performed by using the words GO TO as shown by; GO TO Step 20.
TRANSITION TO A PREVIOUS STEP WITHIN CURRENT EOP/AP shall be performed by using the words RETURN TO as shown by; RETURN TO Step 20.
TRANSITION TO ANOTHER EOP (or AP) should be f
d y
he words GO TO, followed by the procedure e per ormed designator, number, title, and the specific procedure step as shown by; GO TO ES-0.1, REACTOR TRIP RESPONSE Step 20.
I If a specific step is not shown it is to be assumed that transition is to the beginning of the desi nated procedure.
e eszgna e
Transition from an EOP to an AP should not be used.

Standard practices for observing abnormal results need not be prescribed within procedure steps.
6.0 FORMAT OF CRITICAL SAFETY FUNCTION STATUS TREES Critical Safety Function Status Trees (CSFSTs) are block format devices used in the evaluation of predefined safety concerns designated as Critical Safety Functions.
{FIGURE 6 CSFST).
6.1.1 6.1.2 6.1-3 The blocks are aligned so that the user will enter each tree on the left-hand side of its page and move towards the right-hand side.
Each block contains a question concerning current plant conditions.
The question in each block may be dependent on previous blocks.
Each question is written to obtain a YES or NO response.
The response dictates which branch of the status tree will be taken.
6.1.4 6.1.5 6.1.6 Questions should be written so that a
YES response branch will move the user down the page.
I Each possible complete path through the tree ends in its own end point, or terminus.
The last path segment and the associated terminus circle use a color-code and/or pattern-code as shown in FIGURE 7.
Termini should be ordered so that the highest priority condition terminus is at the top of the page and the priority levels descend down the page.
The priority order for color-coding, in descending
- order, is RED-ORANGE-YELLOW-GREEN.

A-502.1:29 APPENDIX A Logic Terms and Conditional Statements The EOP and AP sets are designed to provide guidance for actions contingent upon plant conditions.
Since the procedures provide actions for a variety of conditions it is necessary to use consistent logic terminology and logic statement structure to ensure correct user interpretation.
This appendix delineates the logic terms used in the procedure sets and addresses the specific functions of each device.
Each logic term should be used in its standard form in a procedure to avoid user confusion.
Use of the IF...,
THEN Statement Where an action is contingent upon a definite condition or set of conditions existing when the step is entered an IF-THEN format should be used.
This statement consists of the emphasized IF followed by a description of the required condition or conditions, and the emphasized THEN followed by the action or actions to be performed.
ex.
IF letdown is in service, THEN use auxiliary spray Use of the IF NOT, THEN Statement This statement may provide a contingency action to be used in the event the required conditions of an IF...THEN statement are not satisfied, a desired system/component status does not exist or an RNO action does not obtain the desired result and other action should be taken.
The normal structure of this statement is IF
- NOT, THEN followed by the desired action.
The emphasized IF and NOT may be separated to allow the insertion of other words for statement clarity.
ex.
1)
IF letdown is in
- service, THEN use auxiliary spray.
2)
Verify faulted S/Gs isolated unless needed for RCS cooldown.
IF NOT)
THEN GO TO E-2, FAULTED STEAM GENERATOR ISOLATION, Step l.
3)
IF PRZR pressure less than 2335 psig, THEN manually close PORVs.
IF any valve can NOT be
- closed, THEN manually close its block valve.
4
Use of the WHEN...,THEN Statement A-502.3.:30 The use of this statement provides guidance for the performance of actions which are contingent upon a certain condition occurrin The specified condition is one which is e
ected to need not have oc e occurred to allow continued procedure flow.
The operator is expected to continue on in the procedure and perform unless otherwi the designated action whenever the spec'f' d't'i z.e con x ron is met em hasized WH N o
erwxse dz.rected.
This statement is structured
'th th p
followed by the specified condition, and the wl e
emphasized THEN followed by the action to be performed.
ex.
WHEN ruptured S/G pressure less than 1050 psig, THEN verify S/G ARV closed.

Use of the Emphasized THEN The emphasized THEN shoul d only be used wzthzn the previously

v
A-502.3.:31 Use of the Emphasized OR The OR is used to combine equally acceptable conditions within a step or substep to provide for action direction.
This technique should be used in the inclusive sense such that any one condition satisfies the step, and if more than one of the listed conditions exists the step is till satisfied.
ex.
Depressurize RCS until EITHER of the following conditions satisfied:
PRZR level-GRATER THAN 70%
OR RCS subcooling based on core exit TCs-LESS THAN REQUIREMENTS OF FIGURE 1
When directing actions to be taken the use of OR should be minimized in the procedure sets.
Priorities should be established wherever possible and the procedure written to reflect the prioritization.
Where this is not feasible it may be necessary to use the exclusive sense of the word or and this must.
be specified in the step.
ex.
Start A charging pump OR C charging pump, but not both Combination of Logic Terms Combining any of the previously listed logic devices within individual steps should be minimized to limit the possibilities of confusion and ambiguity.
Where it becomes necessary to combine
- them, great care must be exercised to maintain procedure clarity and definitive direction to the user.
