EMERGENCY OPERATING PROCEDURE  !

WRITERS' GUIDE l 1.0 PURPOSE The purpose of this Writers' Guide is to provide administrative and technical guidance to be used in the development and review of-the emergency operating procedure set.

This Writers' Guide is used to develop the Point Beach Nuclear Plant emergency operating procedures that are derived from the Westinghouse owners Group Emergency Response Guideline Program, Revision 1. This Writers' Guide is not intended for use for emergency operating procedure revisions prior to the date these reformatted procedures are implemented.

i 3.3 Page Identification and Numberino j i

The title page of each procedure will be identified in the title clock 'j by 1) the procedure designator'and number; 2) the' revision number;;3) the.date of issue. Each subsequent page of the procedure will'have- ,

i :only.the, procedure designator and number, along with the pagel number, 'l in the title block. In addition, CSPs will'have colors.across from^ ]

the title block on every page to represent the priority of the 1 feritical safety procedure status tree pcths that are entry conditions. f

.to the CSP. The title of the. procedure will be across the top of each page of the procedure. The word continued will appear at the bottom of each page except the last page. The.last page of each procedure j will ~ additionally be identified by the word ."END" following the last instruction step. This format does not apply to appendices and figures. {

1 4.0 FORMAT 1 d

The. following format is to be applied consistently for all emergency j operating procedures., l 4.1 Procedure Organization

.All procedures in the' emergency operating procedure series will.have f three sectionc. The cover sheet will summarize the procedure intent j and state'either entry symptoms or means of entry. The: operator l actions will ccmprise.the bulk of each procedure and present'the j actual stepwise guidance. A foldout page will summarize information 1 L which is -continually required for, operator guidance... A single foldout ]

page will be used for each emergency operating procedure series. ]

4 The procedures in the CSP seris.s will have only the cover sheet and j operator actions.. :f

,I 4.2 Page Formats The c page will be in a format similar to other plant procedures.

This means it will generally have complete sentences that extend over j the~ entire page width. Each cover sheet vill contain two explanatory sections in addition to the procedure title and title block. The first will be titled " PURPOSE" and will briefly describe what the procedure is intended to do for the operator. The second section is a summary of those symptoms which require entry into the procedure, i This section will be. titled " SYMPTOMS OR ENTRY, CONDITIONS." Certain procedures can be entered primarily based on symptoms; for these procedures a symptom summary is sufficient. Some other procedures can

,4 only.be entered by transitions from previous procedures and a summary ,

of the entry conditions (and procedure step) should be provided. For f

]j with' a quick reference to verify he -is in the correct procedure.  ?

h ,

This description?is not meant-to duplicate the' monitoring function of the status trees. .Becauseof this, every branch of the status tree j

does not need to be described in'this section. This.information should be presented in.a manner that is most useful'for the procedure user.  :

1 All of the operator . actions will be in a. two-column format where the i left-hand column isidesignated for operator actions. The right-hand column is' de.signated for contingency. actions'when the expected response is not obtained. See Figure 1 for a sample of'the page format. q The foldout page .is intended to ~ summarize only that information which

, an operator should'have continuously available, and content will. vary from procedure to procedure. Each foldout page shall be titled

" Foldout for EOP-X Series." l

. 4.3 . Instruction Steps

. Instruction steps in the operator. actions will be numbered and indented as follows:

I l '. Verify ...

a. Check ...

1) Valve (not desirable)  !

a hi 'All innediate action steps will have the step number circled. The 1 same step number scheme is to be used in both the right and left columns of the procedure. Substeps.are lettered sequentially accordingly to desired order of performance, (the (a) level of j indentation above). If the order of knportance is not important then the substeps will not be designated by a letter but will be preceded by'a dash. Use of the third' level of indentation detailed above j 1 should-be minimized. 3 It may be necessary to continue a step from one page to the next.

U This is always undesirable. When a step must be continued to the f next page,: include the following words at the bottom of the initial l page and top of the subsequent page in the Actica/ Expected Response  !

follows:

0 '

5.1.1 ' Instructional' steps will be concise and precise.

, : y

.5.1.2 Short simple sentences or sentence fragments should be used,  ;

m 5.1.3 Complex evolutions should be prescribed in a. series _ of steps, with each step made as simple as practicable. ]

5.1.4 For; instructional steps that involve an action verb relating to three or more objects, the objects will be listed. <

Limits should be expressed quantatively whenever possible.

~

' 5 .1. 5' .

5 .1 '. 6 ~ Mandatory sequence of steps is assumed unless.otherwise ,

stated uActions required in a particular step should not be=

+ expected to be complete before the next step is begun. If' ij assigned tasks are short, then the expected action will- )

probably be completed prior to continuing. However, if an {

assigned task is very lengthy,, additional steps may be performed prior'to completion. 'If a particular task must.be -

completed prior to continuation', this condition must be 'l stated clearly either in the-step or substep, or in a note 3 o r.. caution.

5.1.7 Expected results 'of routine tasks need not be stated. i 5.1.8 When considered beneficial for proper understanding and -  !

performance, provide the system response time associated with performance of the instruction. - '

5.1 9. . . When system response dictates a time frame within which the instruction must be accomplished, prescribe such time frame.

.. Avoid using time to initiate operator actions. Operator actions should be related to plant parameters. j 1

5.1.10 When additional confirmation of system response is considered necessary, prescribe the backup readings to be made.

5.4. -Use of Logic Terms'

{

~

The logic terms and, ,ol, not, g, E not, WHEN, ar,d THEN, are of ten '

necessary to precisely describe a set of conditior.s or sequence' of 1 actions. When logic -statements.are used, the logic terms shall be , '

underlined so.that all the conditions are-clear to the operator. Only i the logic terms g , WHEN, and THEN,'will be full' capitals and i l underlined.  ;

I i

l The following rules shall apply to the use of logic terms:

5.4.1 The use of and and of within the same action shall be i ,

avoided. I; g

5.4. 2 ' When attention should be called to combinations of .;

v conditions, the word and shall be placed between the N' description of each condition. The word and shall not be used to join more than three conditions in paragraph form.

5.4.7 'To be consistent with.stan'dard_ logic, the user o'f the ^!

. procedures should only transfer to:the: contingency column'-

-when the logic statement ( g ..., then1...)'is false. .This

~

i occurs onlylwhen the antecedent is true_and the consequent..is false. Care should be'taken to ensure the operator is not expected to. transfer to the contingency column when the antecedent is false.

5.4.8 'In the contingency column, the user must read the whole contingency for the substep.; ? ' high level-step if there are

~

not substeps) prior to retc %r. to the expected response column. This is the case pr ness of whether the initial

-logic statement ~is true or Ge. This' ensures that important actions are not mined.

5.4.9 In both the expected respceme column and the contingency column, the word IF in a loalc-statement will always be-positioned to be the first word in a line of text. This ,

makes each logic statement more visible than if they are written in standard paragraph form.

b. Start control rod shroud I fans and cavity cooling fans .,

c. Go to Step 4 (RHR)

.5.5 'Use of Cautions and Notes 'l Cautions and notes should not contain operator actions. Cautions and ,

notes can be considered in two categories: 1) those that apply to the '!

entire procedure, and 2) those that apply to a portion or specific step of the procedure. Cautions or notes that apply to the entire  :

procedure are placed at the beginning of the procedure; those that apply to a' portion of a procedure are placed immediately before the l procedural steps to which they apply.

Cautions and notes that are at the beginning of a procedure will be arranged so that standard notes and cautions come first, procedure L

specific notes.and cautions follow, and any notes or cautions that L apply to the first step of the procedure will come last.

A cautica cannot be used instead of an instructional step. It should l1 t be used to denote a potential hatard to equipment or personnel associated.with or consequent to .he instructional step.

Use'of Underlining )

can also be used to provide added emphasis'.to key-words.in steps.

q

, 5.8 ReferencesandBranchkng"toOtherProceduresorSteps:

9..- .

Referencingfimplies that an additional procedure or additional steps

- willLbe used as a supplement to the procedure presently'being used.

Referencing other steps.within the procedure being used, either future

. steps or completed steps, should be minimized. When only a.fea steps are-involved in the referencing, the steps should be' stated in the fprocedure whenever they are needed.

s To minimise potential operator confusion, branching will be used when the operator is to leave.one' procedure'or step and use another V Lprocedure or step. Use the key words "Go to" or " Return to."

4 Therefore, the operator will'know to leave lthe present step and not

4. y return until directed. Use quotation marks to emphasize the title of the referenced or branched procedure. When branching to a step number,'. include a short description of the high level step in parenthesis following.the number. There should not be any action j verbs in this' description to prevent confusion.

Example: Go to E0P-1, " Loss of Reactor Coolant."

Go to Step 20, (reactor coolant) .

5.9_ Compon rit' Identification m

' With respect totidentification of components,. the following rules are 4 .to be followed:

n - '

5.9.1 ' Equipment,. controls and.. displays,will be identified in' operator language'(common' usage) terms. These' terms may not I always match engraved names on panels but will be complete to ensure. correct' performance.

5.9.2 When the engraved names and numbers on panel nameplates .and

. alarm windows are specifically the item of concern in the procedure, the engraving should be quoted verbatim.

a 1 5.9.3 .The' names of plant system titles are emphasized by initial capitalization. When the word " system". is deleted from the j j title because of brevity and is. understood because of the d

-_ context, the' title is also emphasized by-initial

--capitalization.

K 5.9.4 - If'the component is seldom used or it is felt that the component would be difficult to find, location information' should be given in' parentheses following the identification.

5.10 Leve1 of Detail

-'Too much detail in emergency operating procedures should be avoided in y . the interest of being able to effectively execute the instructions in

~

a- timely manner. (The level of detail required is the detail that a newly. trained and' licensed operator would desire during an' emergency.

condition.

-]

To assist in determining the level of emergency operating procedure '!

'detaili the following general rules apply. j 9

5.10.1 Any information which the operator is expected to know (based l on his training and experience) should not be included, i i

5.10.2 For control circuitry that executes an entire function upon )

actuation of the control switch, the action verb appropriate i to the component suffices without further amplification of j how to manipulate the control device; for example, " Start one J reactor coolant pump per OP-4B."' Recommended action verbs are as follows:

1

a. Use " start /stop" for power-driven rotating equipment.  !

3 j ( b. Use "open/ shut / throttle / pull to lock" for valves.

c. Use " trip /close/ lockout" for electrical breakers.

performed. This'is not necessary when transferring to the-

'first step of a procedure.

Example: Go to Step 10, (reactor coolant).

Parentheses shall also'be used to' indicate alternative items in a procedure, instruction, equipment identifiers, or additional information.

6.3.5- Period Use- a pericd at the end of complete sentences and for ,

- 6.5 ' vocabulary-Words used in procedures should. convey precise meaning to the trained

. person. The following' rules apply: l Use simple words. . Simple words are usually short common-

'l 6.5.1 words of few syllables. -j 6.5.2 Use common usage if it makes the-procedure easier to-understand.

6.'5.3 Use words that are precise rather than vague, specific rather l than general, familiar rather than formal, concise rather 1 than blanket. Avoid using the.words stable, approximately,.

rapidly, slowly or normal.if possible.

6.5.4 Define key words that may be understood in more than one sense.

6.5.5 Verbs with specific meanings should be used.

6.5.6 Equipment status should be denoted as follows: ,

-a. Operable / operability - these words mean that a system, subsystem, train, component, or' device is capable of performing its specified function (s) in the intended manner. Implicit in this definition is~the assumption that all necessary attendant instrumentation, controls, normal and emergency power sources,. cooling or seal water, lubrication or other auxiliary equipment _ required for the system, subsystem, train, component, or device to perform'its function (s).'are also capable of performing L

related support functions.

b. Operating - this word means that a system, subsystem, L.- train, component, or device is ln' operation and is i

!- performing its specified function (s) and that other L conditions do not prevent it frcm maintaining that I service.

n c. Available - this word r ans that a system, subsystem, train, component, or device is operable and can be used as desired; however, it need not be operating.

.L i 6.6 Numerical Values i The use of numerical values should be consistent with the following rules:

6.6.1 Arabic. numerals should'be used.

6.6.2 For numbers.less than unity, the decimal point should be -!

preceded by. a zero; for. example, 0.1. .l

. 6.6.3 The number of significant digits should be consistent with l the number of significant digitt available from the display 1 and the reading precision of the operator.

6.6.4 The symbols for greater and less than (>, <) will be used except.when this would make the step difficult to read.

6 .6.5- . Acceptable values should be specified in such a way that .i addition and subtraction by the user is unnecessary. This can generally be done by stating acceptance values as limits.

1 Examples: 510'F maximum, 300 psig minimum, 580 F:to 600 F.

Tolerances can be expressed by. stating the nominal value followed by the acceptable range in parentheses.

Example : Between 5% and 50%  !

' Avoid - 550*F i 10'F 'l I

6.6.6 Engineering units should always be specified for numerical H, values of process variables. They should be the'same as those used on the control room displays.

6.7 -Abbreviations, Letter Symbols and Acronyms -

' The use of abbreviations or letter- symbols shoold be minimized because' l they may be confusing to those who are not throughly familiar with  !

them. Abbreviations and letter symbols may be used when their meaning is unquestionably clear to the reader / user. Consistent usage should be maintained throughout the procedure. .j i

l PBNP 4.19 Page 18 7.3 Heading and Text Arrangement The cover page of each procedure is composed of two sections, one titled " Purpose" and the other titled " Symptoms or Entry Conditions." A These section headings will be in full capitals and underscored. Any subsections on the title page will be underscored.

The_ bulk of the procedure consists of the operator actions. Each high level step will be in initial capitals with an underscore. The substeps will be indented and will have the initial word capitalized, l All complete sentences will end in a period. The following rules will also be used:

7.3.1 There will be two blank lines above each high level step and one line space below.

7.3.2 There will be at least one blank line between substeps. All substeps will have one line space separating it from the last line of the previous contingency action.

7.3.3 There will be two blank lines below the column headings.

The text will be arranged so the user will not have to rotate any pages to read information. For additional clarification of text arrangement, see Figure 1. (

7.4 Breaking of Words i

Breaking of words shall be avoided. J i

7.5 Figures Figures include graphs, drawings, diagrams and illustrations. The following rules are established:

7.5.1 The figure number and its title are placed above the figure.

7.5.2 The figure field and number / title must not violate specified l

page margins.

7.5.3 The figure field should be of sufficient size to offer good readability.

7.5.4 The essential message should be clear; simple presentations are preferred.

t 7.5.5 Labeling of items within the figure should be accompanied by arrows pointing to the item.

7.5.6 The items within the figure should be oriented as naturally as possible. For example, height on a graph should be along the vertical axis.

7.5.7 In general, items within the figure should be labeled.

7.5.8. All lines in figures should be reproducible.

I 7.6 Tables ~ j Tables should by typed using the following rules:

7.6.1 All tables should be evaluated to determine:if a title or table number is necessary. If a title would.not be. ,

q beneficial to the user, it should not be used. l 7 . 6 .' 2 'A heading should be entered for each column and centered j within the column; the first letter.of words in the column )

headings should be capitalized.

7.6.3 Horizontal 11nes will'be placed above.and below the column i headings. vertical lines will be used to. separate columns.

7.6.4 Tabular headings should be aligned as follows:

a. Horizontally by related entries

b. Vertically by decimal point for numerical entries

c. Vertically by first letter for word entries; however, j run-over lines should be indented three spaces. {

7.6.5 There should not be a vacant cell in the table. If no entry is necessary, "NA" or "- " should be entered to indicate not I applicable. )

~

7.7 Cautians and Notes.

j A1.L antes and cautions should be distinguishable from the rest of the

. text by using' the following format:

7.7.1 The applicable heading " NOTE" and " CAUTION" should be _

j capitalized and placed three line spaces below the preceding text when possible.

7.7.2 The text of the note or caution should be in block 'ormat.

The word note or caution should be in the step column and the '

text should extend to the right-hand margin of the page. l A

7.8 U_se of Foldout Pages When used, a foldout page is treated as a single pt., It should follow a single column format similar to the cover p > except the width is different. The page should be folded so that a small margin exists between the fold and the right-hand edge of standard pages. '

This will reduce wear of the fold.

7.9 Use of Oversized Pages Oversize pages shall not be used except as foldouts. ,

7.10. Use of Reduced Pages ,

Reduced pages should be avoided whenever posssible. Final size of reduced pages should be standard page size. Reduced pages should be -

readable.

Page 21 TABLE 1-n- DEFINITIONS OF KEY WORDS AND PHRASES IN THE E0P PACKAGE AVAILABLE

-Available implies that the system is producing the desired result'or'is ready for use. This word is often used to present another, less desirable, method or system for producing a desired effect. 'If the system is not ready for use, the alternative method'should be used.

Example: IF. auxiliary spray is not available, THEN use one pressurizer POSV.

CHECK Observe a system or parameter to determine its present condition. When

" check" is used there will always he- criteria included (possibliin a sWasequent substep) to be used in the evaluation. The word " check" alone does not ' imply that any action is to be taken beyond observing the condition.

Example: Check if SI is Actuated DO NOT PROCEED. (D0 NOT CONTINUF. .)

The procedure user should not continue in this procedure until the desired condition that follows is obtained. If another procedure is-being done concurrently, it does not have - to be halted but the operator should be cauticus to avoid taking any- actions that ' this statement is attemping to avoid.

Example: Do not proceed to next step until RCS pressure is reduced to 1200 psig.

,. GO TO'(RETURN TO)-

This' phrsse tells the procedure user to leave the . procedure at this point and continue executing procedure steps beginning with the' step number-in-this statement. The user.will sometimes be instructed to go to an earlier-step ~in'the procedure (i.e., " Return to") or'a later step in the procedure (i.e., "Go'to") or'another procedure altogether. Whenever the. user leaves a procedure, prior. to 'the end, i. ribbon should be inserted as a page. marker.

Often the procedure.that the user'is transferred to will"have an instruction to " return,to the procedureJ in effect." This page marker will allow the

' user- to " continue thel original procedure where it was -left off.

INTACT' r " Intact".specifically refers to'a steam ge'erator n that-is neither faulted nor raptured. This means the, steam generator does not have a secondary depr6ssurization or'a tube rupture. 0ften if neither steam' generator is

. -intact, one-of.them will have to be considered intact to complete necessary-actions:in the procedure. This is also described in the appropriate'

. procedure.

-Examples- Depressurize Intact Steam Generator to 250 psig.

Intact can also be used more generally to describe a pressure boundary that g is not relieving.

LOCALLY

~ This. word is used to' remind the procedure user that the action that follows cannot be executed from the control room.

can be done from the control room.

Example: CAUTION: IF RCS PRESSURE DROPS BELOW 150 PSIG, THE RHR PUMPS MUST BE MANUALLY RESTARTED TO SUPPLY WATER TO THE RCS.

OPERATE This word is.used to allow the operator to manipulate a particular control or cycle equipment in order to establish or maintain a definite criteria.
