1.0 INTRODUCTION
This Writer's Guido for Eternency and Abnormal Procedures was prepared for use at McGuire Nuc' ear Station. Duke Power Company. Much of the information
~
in the guide is applicable to procedures in general. However, the guide is intended specifically for use in preparing emergency procedures (EPs) and abnormal procedures (APs). Whenever the word "procedure" is used alone, it should be assumed to refer to both EPs and APs.

Institute of Nuclear Power Operations, "Emergency Operating Procedures Writing Guidelines," INP0 82-017. July 1982 1.2 Purpose This writer's guide provides specific guidance in the preparation of emergency and abnormal procedures. Readability and accessibility of O
information are of major concern. The purpose of the guirie is to ensure that writers produce procedures that are readable, complete, convenient, accurate, consistent, and acceptable to control room personnel.
1.3 Guide Information Before attempting to develop or review procedures, the writer should become thoroughly familiar with the EP/AP section of OMP 1-2, Use of Procedures, as well as the information in this guide. This section introduces some ideas for the use of the guide and its difft. rent sections.
1.3.1 Guide Structure General principles such as formatting and guidance on procedure style and content are in the main body of the document. Examples of procedures are located in appendices, as are several other aids, including:
e Otettonary of Acronyms and Abbreviations e
Constrained Language List e
Punctuation Handbook 6
Guidelines for Word Processing.
O Response to Supplement 1 to NUREG-0737,Rev. 4
1 PAGE 2 0F 40 1.3.2 Guide Usage The best way to use the guide is to start by becoming familiar i
with its structure. The Table of Contents is a detailed outline of how the guide is structured.
The writer's guide is intended as a reference for the writer when writing emergency or abnormal procedures.
It has tabs to aid in quickly accessing required information. The Table of Contents may also aid in identifying the section containing l
information being sought.
The information in the guide is structured so that pertinent l
information needed to develop a procedure is covered first and t
l that used to enhance the procedure is covered later in the guide.
While collecting information and organizing the procedure, the section on the procedure development process, Section 1.4,
't will be the most helpful. For procedure format information, i
the fcreat principios section, Section 2.0, is the appropriate reference. For constructing sentences and developing notes i
and cautions, the style and and content section, Section 3.0, will provide the appropriate guidance.
For an example of both an EP and an AP, refer to Appendices 1 i
and 2.
For acceptable abbreviations, refer to the Dictionary j
of Acronyms and Abbreviations in Appendix 3.
Refer to the Constrained Language List in Appendix 4 when selecting appropriate terms. Appendix 5, Punctuation Handbook can be l
referenced for guidance on correct punctuation. Guidelines
}
for Word Processing in Appendix 6 provides proper layout and spacing information for those typing and proofreading the procedures.
EPs will be verified and validated in accordance with the procedures contained in OMP 4-2, Verification Process For l
Emergency Procedures and OMP 4-3, Validation of Emergency Response Capability System. Verification is a two phase process in which both written correctness and technical l
accuracy are verified. Validation ensures the procedure.
plant, operator and training work together to manage an l
emergency condition.
I 1.3.3 Guide Changes The writer's guide will be maintained by the Operations Document Development Section. Reconuended changes should be addressed to ths Operating Engineer, Occument Development, j
Revisions to the writer's guide will be approved and issued in 1
the same manner as Management Procedures as esplained in j
Section 9.0 of OMP 1 1 Administration of Operations Management Procedures.

PAGE 3 0F 40 1.4 Procedure 06velopment Process C/
This section is intended to help the writer prepare to write. It is important that the appropriate references and information, including the writer's guide, be readily available.
1.4.1 Procedure Developoient Objectives There are certain requirements of procedures to be used by control room operators during emergency and abnormal l
operating conditions. Operators must first of all trust that the information within their procedures is I
technically accurate and complete. Operators must also f H4 that the information presented is easily accessed, read, and understood. The procedure writer must be familiar with the rules of usage for EPs/APs as outlined in OMP 1-2, Use of Procedures, e
Technical Accuracy: Procedures must be technically complete and accurate. Energency procedure content is to be based on plant-specific Emergency Procedure Guidelines (EPGs).
6 Information Presentation: The writer's guide provides information for translating the technical information into procedures. The procedure writer must present technically accurate information so that the user can understand it. In addition, the guide ensures that procedures will be consistent in organization, format, style, and nontechnical content.
1.4.2 Collecting Information The procedure writer must collect information in two categortes: technical information and user inforeation, i
Both are equally important sinse a technically accurate j
procedure may not be user friendly if the user was not considered during the development process.
1.4.2.1 Technical Information To ensure technical accuracy, the most up-to-date technical inforration should be collected.
Sources of this information should include engineering drawings, system i
l descriptions, vendor manuals, Technical l
Specifications and plant-specific Emergency Procedure Guidelines, i
i O Response to Supplement 1 to NUREG-0737,Rev. 4 i
PACE 4 0F 40 1.4.2.2 User Information The amount of user information collected will have an affect on a procedure's level of detail. Enough detail should be included such that the least experienced, qualified user can use the procedure.
1.4.3 Drafting The Procedure The drafting stage will be a major factor affecting whether a procedure becomes a geod usable document. The writing style should place minimal demands on the user and should r.:tch the user's language ability. In drafting, the writer should strive to:
e Use the appropriate and correct format and writing style according to the requirements of Sections 2.0 and 3.0 of this guide.
6 Make the procedure readable.
I o
Make the procedure easy to use and understand, o
Express idaas clearly and concisely.
+
Use consistent format, stylo, and technical content.
A copy of this guide should be available for referencing whenever writing or revising procedures.
When the procedure is complete, it should be reviewed to ensure accuracy, adequacy and usability. Following the review, revisions may be required. Any revision should adhere to the same requirements as the original draft.
6 1.4.4 Reviewing the Procedure The procedure writer should perform a self-review of the i
procedure prior to the formal review process. The l
Verification Checklists from 009 4-2, Verification l
Process for Emergency Procedures, can be used to analyze the specific technical content, human factors, and constunication features of the procedure. A technique called structured reading can also be used to objectively analyze and review a procedure. Section 4.2 of the NPD Procedure Development Guide describes this technique, I
i Refer to APM 4.2, Administrative Instructions for l
Permanent Station Procedures, for administrative l
requirecents. By following APM 4.2, it is ensured that t
the appropriate persornel formally review and approve the procedure throughout the development process.

3 The EP verification process has two objectives:
e Written Correctness - To ensure that procedures conform to the format and other principles specified in this writer's guide, e
Technical Accuracy - To ensure that the procedures are technically accurate, consistent with i
plant-specific EPGs, and include all appropriate Itcensing comitments.
Procedure verification shall be performed in accordance with OMP 4-2, Verification Process for Emergency Procedures.
1.4.6 Procedure Validation I
The EP validation process will be used to ensure that procedures are:
Structured logically to provide sufficient i
information for qualified operators to perform their duties in an emergency, e
Compatible with plant responsis, plant hardware, training, and available staffing.
The validation process will be perfonned in accordance with OMP 4-3, Validation of Emergency Response Capability System.
l 1.5 Procedure Change Process When changes occur in the plant design. Technical Specifications, writer's guide, plant specific EPGs, or other plant procedures that affect the EPs or APs, the procedures shall be revised promptly to reflect these changes. The Operations Occument Development section i
will handle EP/AP changes and is responsible for reviewing the changes to ensure that the appropriate consistency is maintained with the plant-specific EPGs, and with the writer's guide.
Procedure changes shall be made in accordance with OMP 1-2, use of Procedures.
1 1.6 Procedure Availability And Accessibility l
The EPs and APs will be located in the Control Room and in the l
Technical Support Center (TSC). They will be separately bound ard t
uniquely identified by procedure number and title.

2.1 Organization Of Procedures All EPs and Aps are to have a comon structure consisting of the elements shown below. 7hn format shall be procedure text divided into i
sections, followed by enclosures. Subprocedures having separste text i
and enclosures are used to describe additional, subsequent ac', ions necessary to regain normal plant conditions or to accomplish'6hutdown.
The AP format shall be the same as that of the EP, except tha: AP subprocedures are designated as ' cases' and include symptoms nnd inenediate action sections as well as subsequent action sections.

1 2.1.2 Table of Contents l
C' Prepare a Table of Contents only for APs that have more than one case.
Identify the title and page number for each case within the procedure. EPt, do not utilize a table of contents due to the controlled nature of EP transitions and the referencing of specific step numbers in the transition statements.
2.1.3 Purpose The purpose statement should briefly state the objective (s) to be achieved through use of the procedure. Because the purpose statement is a training aid, and not expected to be read during performance of the procedure, there are ne stringent format requirements (see Appendices 1 and 2).
2.1.4 Symptoms or Entry Conditions This sectton is a summary of those conditions which require entry into the procedure.
For all APs and for EPs that are entry procedures into the E?
set (EP/01, EP/09) a susmary of the s)eptons (plant conditions, alarms, etc.) should be provided. Symptoms should be listed in order of importance, with the most important one mentiorld first. The importance of a symptom is especially i
O' relates to its ability to identify a particular condition.
Symptoms found in several abnormal conditions should be listed last. Use bullets (6) to list the symptoms (see Appendix 2, page 2).
For EPs which can only be entered by transition free previous procedures, a suusary of the entry conditions, including procedure number and step number, should be provided. These entry conditions will be listed using bullets, i
Example:
5.
Entry Conditions This procedure is entered from:
e EP/2/A/5000/01, SAFETY INJECTION, step 13, when a Pzr PORV is stuck open and its isolation valve can not be closed.

! mediate Actions Specify the imediate operator actions to be taken for the procedure in the two column format described in Section 2.3.
L,imit imediate actions to those positive steps that must be performed before there is an opportunity to refer to the appropriate procedure.
If there are no imediate actions, write "None" below the section heading.
2.1.6 Subsequent Actions Specify the operator actions necessary to return the plant to a normal, stable, or safe, steady-state condition. Use the two column format described in Section 2.3.
After the last step in the Subsequent Actions section, write the werd '
centered on the page in capital letters and underlined. igt",
2.1.7 Enclosures Append any materials (e.g., graphics, parts of reference 6 JPs, or operator aids) that are neither included in the body of the procedure nor imediately available in the control roce, but which are essential ta carrying out the procedure. Appended materials are to be called "anclosures" and are to be located at the end of the procedure. Foldw t pages should be used for enclosures when the operator is required to refer to an enclosure frequently. Text in enclosures may use the tue column format or the single column, full page width format.
O Arrange enclosures in numericril order.
2.1.8 subprocedures (EPs only)
Subprocedures are additional actions which would be included under "D.
Subsequent Actions", but lend themselves to beine separately bound for Control Room use. Subprecedures contale procedure text and enclosures necessary to regain normal plant conditions or to accomplish shutdown. EP subproc:dures are identified by an a441tional number designator in the precedure number:
Examples:

PAGE 9 0F 40 2.1.9 Cases (APs Only)
Abnormal procedures may be divided into cases to address related transients or conditions. The following formatting requirements apply to APs containing cases (seo example in Appendix 2):
+
Cases shall be designated with Roman numerals (e.g., Caso I, Case II, etc.).
The AP purpose shall appear on page one of the pr.
jure.
Each case shall contain a S m toms, Innediate Actions and a Subsequent Actions section.
2.2 Page Format All pages of the EPs and APs, with the exception of the cover page, shall use the same page structure This page structure uses a pre-printed border with page heading boxes. The pages containing operator action steps shall be writtan in a two-column format within the printed border.
2.2.1 Page Headings The page heading consists of three blocks of information that 13ay include:
O
+
Procedure /subprocedure number
+
Procedurs title
+
Case designation and title (APs only),
+
Enclosure number and title
+
Page number.
2.2.1.1 Procedure Number In the left block of the page heading include the procedure number.
Example:
EP/1/A/5000/01 The procedure number is a unique identification number developed in accordance with Section 4.2 of the AFM.

i PAGE 10 0F 40 2.2.1.2 Procedure Title O
Provide a short but descriptive title to allow the operator to easily identify the procedure and the conditions under which the procedure should be used.
Locate the title on each page, except for the cover page, in the upper center as shown in the example in Appendix 1.
On the cover page, locate the, title in the space provided.
2.2.1.3 Case Designation A4;d Title (APs Only)
If there are cases within an AP, provide the case designation and title directly below the procedure title.
Initially capitalize the major words tri the case title and designation.
Examples:

PAGE 11 0F 40 2.2.1.5 Page Numbers s
The cover page of all procedures is not numbered.
For procedures with a Table of Contents, identify the page with an "i" in the upper right heading block.
If necessary, use "ti", etc., to identify any succeeding pages of the Table of Contents.
The remaining pages of the procedure are numbered in consecutive order in the "Page of
" format.
The first number is the sequentTaT page and the second number is the tot 41 pages. Do not include enclosures in the total page count.
Example:
PAGE NO.
2 Of 6 Each enclosure is numbered separately using the same format. Place the page number in the upper right heading block.
2.2.2 Two-Column Structure The pages for presentation of operator action steps shall use a two-column format within the printad border. The left column is designated for expected opera *.or actiun and response, and the right column is designated for contingency actions when the expected response in the left column is not obtained. These columns shall be titled "ACTION / EXPECTED RESPONSE" and "RESPONSE NOT OBTAINED".
2.2.3 Page Breaks Start separate pages for the following:
Cover page e
Table of Contents e
Each EP subprocedure l
6 Each case (APs only)
+
A.
Purpoca 6
C.
Innediate Actions (EPs only)
I
+
Each enclosure When possible, avoid splitting steps or substeps between pages.
Cautions and Notes should not be carried from one page to another. Additionally, the caution or note statement should appear on the same page as the step /substep to which it i
applies.
' O Response to Supplerrent 1 to NUREG 0737,Rev. 4 I
PAGE 12 0F 40 2.3 Step Format g
Step numbering and indentation contribute to a procedure's readability. Numbered steps help users keep their place in a sequence of tasks.
Indentation creates "white space" on the page, which is a "space clue" to users as to what level they are working on (step, substep, etc.) Whenever possible, do not split steps and related substeps between pages.
2.3.1 A/ER Column For the "Action / Expected Response" column, use high-level action steps with lower level substeps. Substeps are lettered / numbered sequentially according to expected order of performance.
Example:
1.
High-level step a.
Substep 1)
Substep a)
Substep.
If the substep order is not important, or they comprise a list, the substeps are designated by bullets (+).
Example:
Verify VI valves to Containment - OPEN:
+ 2VI-1298 (A Ess Header Cont Isol Otsd)
+ 2VI-1608 (8 Ess Header Cont Isol Otsd)
+ 2VI-1508 (Lwr Cont Non Ess Hdr C/I Otsd).
2.3.2 RNO Column Do not number high level RNO steps. They will appear directly across from their high level step in the A/ER column.
Designate RNO substeps as follows:
+
If the A/ER substep has a specific RNO substep, then place the RNO substep directly across the page from the A/ER substep and number / letter it the same as the A/ER substep.
Example:
A/ER RN_0
- a. Any NC Pump -
- a. Verify natural RUNNING circulation.
O Response to Supplement I to NUREG-0737,Rev. 4
F PAGE 13 0F 40
+
If the A/ER substep is designated oy a n
letter or number and no RNO exists for the substep, then (v) the corresponding space in the RNO column will be blank.
If a RNO applies to the high level step, then the RNO substeps are numbered based on sequential performance (number / letter) or nonsequential/ list (bullets). In these cases the substeps in the RNO column will not match the substeps in the A/ER column.
Examples:
RR A.

(50 F Pumps running).
2.3.3 In-Text Graphics Procedure graphics are nontext materials that support a procedure, such as graphs and tables. Usually graphics are included in a procedure as enclosures. !aall tables (less than a full page) may be integrated into the body of a procedure for the convenience of the user.
When a table is integrated into the body of a procedure it should be placed imediately following the step where it is first mentioned.
Tables may extend across the width of the page and are not limited by the two-column (A/ER, RNO) format.

3.0 STYLE AND CONTENT OF PROCEDURES The following approach to style and content emphasizes the use of concise performance steps. Information should be presented in a simple, familiar, and unambiguous manner. Consistency in style and sentence structure improve the readability and understandability of the procedure. Applying the following guidelines will ensure that style and content remain. consistent from procedure to procedure.
3.1 Step Sent'ence Structure 1
The structure of a step affects the rate at which it is reart and understood. The following guidelines will aid in developing steps that are read quickly and are easily understood. The guidelines apply to both the "Action / Expected Response" (AER) and "Response Not Obtained" (RNO) columns unless otherwise specified.
3.1.1 Comand Statements Write action steps as simple conmand statements. Begin the sentence with an action verb (e.g. open, close, verify, etc.)
followed by the object of the action (usually the equipment name).
Examples:
Action verb Object A.
Check NC pressure.
B.
Close 1NI-1788 (Train 1B ND fo C & D CL).
Add other gramatical elements such as adverbs (action verb modifiers) or object modifiers as necessary to convey the appropriate instructions.
Examples:
Adverb Action verb Object A.
Manually operate equipment Action verb Object Object modifier B.
Throttle CA flow to maintain NR level 30%.
Use short sentences and conditional statement clauses (conditional statements are di scussed in Section 3.2).

PAGE 16 0F 40 Use the same sentence / clause style for main Steps as well as substeps.
3.1.1.1 A/ER Column Steps in the A/ER column show expected responses or indications to operator actions following a comand statement in all capital letters. Separate the expected response from the action step with a hyphen. If a high-level task requires multiple actions, then specify subtasks. Following each subtask, show the expected response. Do not shott expected responses for simple control manipulations or actions.
Examples:
A.
Check S/G NR levels - GREATR THAN 5%.
B.
Check Containment conditions:
+ Containment pressure - NORMAL
+ Containment Sump level - NORMAL.
3.1.1.2 RNO Column Unlike the AER column, action steps in the RNO O
column are written in sentence format. Do not show the expected responses in the manner discussed in Section 3.1.1.1.
When contingencies exist for an RNO step, use statements separated by a space for each alternative action.
Example:
A/ER RNO Check Pzr PORVs - CLOSED IF "Pzr Press' less than 2215 PSIG, THEN ranually close PORVs.
IF any valve can not Se closed, T_N_EN maaually close its Isol valve.
If the RNO contains multiple contingency actions for a single high-level action in the AER column, the phrase "Perform the following:" should be used in the introductory high-level statement.

following:
a.
Verify Sp components on.
- b. Verify NS Pump flow.
- c. Stop all NC Pumps.
- d. Stop all RV Pumps.
- e. Ensurs VE Fans running.
As a general rule, all contingent transitions to other procedures should take place out of the RNO column. Deliberate transitions may be made from the AER column.
3.1.2 Positive Statements Avoid using negative words in the A/ER column when possible.
O Write instructional or procedural steps as positive statements. Generally, positively stated sentences / clauses are more readily comprehended.
Examples:
A.
THIS -- Maintain cooldown rate less than 100'F/hr.
B.
NOT THIS -- Do not cool down greater than 100'F/hr.
3.1.3 One Thought Per Step Use only one main action per procedure step. Do not combine unrelated actions into a compound.entence or clause. A compound sentence or clause that combines related actions is acceptable, however, the inclusion of more than one action in a procedure step should be avoided. Ses Section 3.2.2 for guidance on-the use of.
"and".
Examples:
A.
THIS -- Verify ECCS operation and flow.
B.
THIS -- IF NC pressure less than 1520 PSIG, TREN ensure correct valve alignment and NI pump operation.

3.1.4 Performer Identification For instructional or procedural steps, use the understood "you" as the subject of each sentence. When a step is written, such as "Check S/G 1evels," the understood subject is the Control Room Operator.
Where actions stated in the procedure are to be performed by someone other than the Control Room Operator, identify the performer of the action.
Example:
THIS -- Notify chen.istry to tample NC System boron concentration every eight he'Jrs.
The word "locally" should not be used as a "performer identification" word. Although to "locally" open an MOV implies that an operator must be dispatched, this is not the intended function of the word. "Locally" only specifies that an action to be performed outside of the Control Room is to be done at the specified component or device when other alternatives exist (e.g.,
local control panel, ASP, etc.). When "locally" is used in an action step, "dispatch operator" should also be used.
Example:
THIS -- Dispatch operator to locally stop NF Pumps.
"Locally" does not have to be used if the location of the component or device is included as a substep.
I Exampie:
THIS -- Dispatch operator to open Sequencer DC control power breaker:
+ A Train, 2EVOA Bkr 6 (Vital Battery Area 733')
i 6 8 Train, 2EVD0 Bkr 8 (Vital Battery Area 733')

3.2 Conditional Statement Structure g, g, IF NUT, THEN, and WEN are used in The logic terms g,be a set of conditions, to sequence action steps procedures to descri contingent upon conditions, or to express complex combinations of conditions and actions. Each of these logic terms has a specific function and should be used consistently throughout the procedures and in accordance with an accepted convention. When used in combination, care must be taken to avoid vague and difficult to understand instructions.
3.2.1 Use Of g, IF NOT, WEN, and THEN, When action steps are dependent upon certain conditions or combinations of conditions, begin the step with the words IF
~~
or WEN follcwed by a description of the condition or conditions, and the word THEN, followed by the action to be taken. Use IF for an unexpected but possible condition. Use WHEN for an eipected condition. Generally, the operator should proceed with the next steps in the procedure and complete the action for the WEN statement upon meeting the stated conditions.
If the operator mus*. remain in the step containing the WEN statement until it can be completed, clearly indicate this requirement in the step. Conditional statements should not be started in the middle of a line but at the beginning of the column on the next line down.
Examples:
A.
E, THEN and WEN used correctly.

This statement should be written:
Check if NC pumps can be started.
The two-column format equates to the following logic: "!F NOT' the expected response in the left-hand column, THER'~
perform the contingency action in the right-hand column."
These implied logic terms should not be repeated in the right-hand column contingency. However, logic terms may be used to ensure there is no confusion as to what condition (s) the RNO step actually applies, and to introduce a secondary contingency in the right-hand column.
Examples:
A.
A/ER RNO Check Pzr PORVs - CLOSED IF Pzr pressure Tess than 2215 PSIG, THEN manually close PORVs.
8.
A/ER RNO Any NV Puup running and IF NV Em'ps aligned for S! flow, aligned for normal TREN perform the follevine:
O charging.
- 1) Ensure RN aligned to A8 non-essential header.
- 2) Start #1 PD Pump.
- 3) Close 1NV-238 (Chargir.g Lir,e Flow Control).
The word THEX should not be used at the end of an action to provide instructions for additional action within the same step, because it runs actions together.
Example:
A.
THEN used incorrectly.
Notify Chemistry to obtain NC boron sample, THEN adjust VCT Makeup Control System for shutdown boron concentration,P_ER OP/2/A/6150/09, BORON CONCENTRATION CONTROL.
IF NOT logic statements can be confusing, so do not use the logic term IF NOT. Where different actions are required for two possible conditions, state each condition with its required actions.

3.2.3 Use Of M The word "or" will be used in the following four ways:
e Use the word OR in logic statements to call attention to aTternative combinations of b
conditions. Use the logic word M in the inclusive sense (any one or all conditions may i
be present).
Example:
A.
OR used correctly as a logic term TTnciusivesense).
THIS-- IF Reactor Vessel UR Level less than 97%
DE Pzr level. behavior indicates upper fiead void,1NtJI increase Pzr level to 50% (78%).
+
When "0R" is used to call attention to alternative conditions that are not incorporated into a logic statement format, the "0R" should be capitalized and centered between the two conditions.
"0R" used in this manner should not be underlined to ensure it is not mistaken for a logic term. When used to give O
alternative conditions, "0R" should be used in the inclusive sense (any one or all conditions ray be present).
Example:
l A.

)
+
Total feed flow available to intact i
S/G(s)-GREATER THAN 450 GPM OR NR Lvl in any intact S/G - GREATER l
THAN 5% (18%).
+
"0R" is also used to list alternative operator actions. The use of alternative actions should i
be minimized and priorities established where possible.
If priorities cannot be established, and alternative actions are equally acceptable, then it is necessary to use "0R" in the "exclusive sense" (one and only one of the i
alternative actions is to be performed). When l
"0R" is used in the exclusive sense, the step l
should clearly indicate only one of the actions is to be performed.

3.3 Individual Steps The procedure user is trained to perform every action step and to perfore it in the sequence given unless the procedure specifically states otherwise or unless bullets indicate sequence is not important.
Action steps and conditional statement structures are discussed in Sections 3.1 and 3.2.
Use the following guidelines when developing procedure steps.
3.3.1 Step Sequencing Technical necessity shall be the overriding consideration for sequencing tasks and action steps. However, control room instrument arrangements should also be considered. In general, use the following guidelines:
4 Write action steps in the order in which they are to be performed or verified to have occurred, o
Some series of steps must be performed in an exact sequence.
Indicate these steps by using the previously designated alphanumeric system.
+
Indicate nonsequential substeps by placing a bullet (*)
prior to each substep.
Consider control room layout when sequencing steps. If technical sequence is not important, order steps so that the operator moves lef t-to-right or right-to-left along l
l the control board.
I' 3.3.2 Verification Steps Verification steps should be used to determine whether the objective of a task or a sequence of actions has been achieved.
O Pesponse to Supplement 1 l

PAGE 26 0F 40 i
Separate verification stecs/substeps should be used following pl a sequence of automatic or manual actions, or to ensure iV prerequisite conditiont before initiating an action, l
3.3.3 Diagnostic Steps To aid operators in verifying that they are in the correct procedure or section, and to direct them to the correct procedure or section when necessary, diagnostic steps should
'be included in EPs. These steps should assist the operator in determining the cause of alarms or automatic protective systems actuation and direct him to the appropriate procedure or section.
For diagnostic steps, first instruct the operator to verify or check for a condition. Criteria that the operator will use to evaluate a condition, including expected values, should be shown as substeps or listed with bullets (*) in the left i
column.
Conditional statements should be used in the right coltan to provide transitions to another step, section, or procedure.
Example:
A/ER E
Check Containment conditions:
GO TO EP/1/A/5000/02, HIGH ENERGY LINI E MAK e
Containment radiation INSIDE CONTAINMENT, monitors 1 EMF-51A, 518, step 1.
1 EMF-), 1 EMF NORMAL e
Containment Pres - NORMAL Containment Sump Ly1 -NORMAL "Ice Cond Lower Inlet Doors Open" alarm (1AD9-AS) - DARK.
i 3.3.4 Nonsequential Steps Some operator actions may be required during performance of a
[
task, but not at a specific point in the sequence of steps.
For example, some steps may be performed when a certain l
parameter such as temperature or level is reached, but not before.
l Locate nonsequential steps at the first possible point at which they may be required.
Write nonsequential steps so that the operator clearly understands when the action is to be performed.

l WHEN NC System subcooling reaches O'F, THEN decrease charging flow to 32 GPM while maintaining subcooling.
3.3.5 Equally Acceptable Actions When any one of several alternatives is acceptable, describe the action to be taken and list all of the alternatives below.
Use a bullet (e) to designate each alternative.
Example:
4 Start one of the following NC pumps:
e NC Pump 1A
+
NC Pump 18 o
NC Pump 1C e
NC Pump 10.
3.3.6 Recurrent Steps Recurrent steps are actions that may need to be repeated at various intervals. These steps will usually require the operator to monitor or control some plant parameter.
If the intervals are easily defined (for example, following specific plant responses), repeat the step at each point at O
which it is to be performed.
If the intervals are not specific, describe conditions that require repeating the steps, and those for which the step is no longer required.
Recurrent procedure steps do not require placekeeping aids.
Notes shculd be used to remind the operator of the repetitive monitoring or controlling actions required by recurrent steps.
Recurrent steps may also be incorporated into an enclosure and used as a f11dout page to remind the operator to continuously monitor or
'rform specific tasks.
3.3.7 Time Dependent Steps Some operator actions are required at specified time intervals or some time after an action has taken place.
In writing time-dependent steps, specify the time intervals as precisely as possible. Give the operator information about the time interval involved fo11cwed by the action to be taken.

3.4 Cautions Cautions are informational statements u' sed in the procedure along with the steps. Cautions never contain required action steps.
3.4.1 Purpose Caution statements shall be used to attract the operator's attention to essential or critical information which must be observed to prevent actions which could result in damage to equipment, loss of plant stability, injury to plant personnel, or endanger public health and safety.
3.4.2 Format Designate cautions as follows:
+ Capitalize, underline and use bold type for all letters in the word CAUT!0N.
O
+ Write cautions across the page from margin to margin using bold type. For exact margin settings, see Appendix 6.
6 Multiple cautions under a single heading shall be l
l separately identified by noting them with bullets (+).
3.4.3 Content Make caution statements brief. Only include essential information. The following information, where applicable, should be contained in caution statements, ordinarily in the order indicated:
Precautions necessary to avoid or minimize the hazard Specific nature of the hazard-
+
Location of the source of the hazard i
+
Consequences of failing to heed the caution

Caution statements shall not contain action steps. If an action is required, write a step, not a caution.
Passive action.tentences (usually using "shall," "should," or "may") may be used to provide emphasis to caution statements, and to clearly separate them from steps. Do not use the methods described in Section 3.8.4 for emphasis within cautions as a general rule. For example, do not capitalize and underline logic words such as "if", "then" and "not".
However, fully capitalize procedure titles and capitalize the first letter of each word in specific nomenclature and system names.
3.4.4 Placement Place cautions imediately before the steps or substeps to which they apply.

3.5 Notes Notes are informational statements used in the procedum along tsith the steps. Notes never contain required action steps.
3.5.1 Purpose Note statements are included to provide advisory or administrative information to the operator concerning specific steps or specific sequences of steps. This information should enhance the understanding of the procedure and would otherwise be difficult to find and incorporate into the procedure.
Notes generally should contain information that is of most use to the inexperienced operator to aid in interpreting steps.
Notes must be brief and easily understood, i

nomenclature and system names.
3.5.3 Placement Place notes imediately before the steps or substeps to which they apply. If a note is genaral enough to apply to an entire a
procedt.re, subprocedure or section, place the note before the first action step.
3.6 Referencing and Branching Referencing within and between procedures should be kept to a minimum.
It is better to reproduce small sections of a procedure than to reference the operator to another procedure or section.
3.6.1 Definitions The term "referencing" means routing the user to other steps or sections within the same procedure or to another procedure.
After performing the referenced instructions, the user returns j
to the point from which he was referenced.
The term "branching" means routing the user to another procedure or series of steps in the same procedure. The user does not return to the initial procedure or step.

6 Genetally, avoid abbreviating words, phrases, or names unless the system or component is frequently and comonly referred to by an abbreviated form. Use only the dCCepted abbreviations or 4Cron ps found in Appendix 3.
If a single abbreviation can represent two different words, ensure the context of the sentence clearly denotes the intended use of the abbreviation. If it is possible an operator inay confuse the meaning of the abbreviation; spell the words.
O Response to Supplerrent 1 to NUREG 0737,Rev. 4
PAGE 35 0F 40 a
m e
To make an abbreviation or acrorym plural, add a lower case "s":
e.g. CFPTs, not CFPT's. Reserve the apostrophe for indicating possessive cases.
When referring to specific operating devices or equipment, use the precise label nomenclature, including abbreviations, acronyms, or symbols.
The following symbols may be used:
% Percent
= equal to
'F Degrees Fahrenheit
'F/hr Degrees Fahrenheit
'C Degreer Celsius
+
Plus Minus inches Feet Number Ordinarily, the above symbols should be used when the text includes numerals. When a number or parameter is written as a word, the word description of the symbol should be used. However, if necessary to enhance the readability of a sentence, a combination of symbols, numbers and words may be used.
O Inequalities are to be expressed in words rather than symbols: 1.e., "greater than, less than". Tnese words are always appropriate for comparing pressures, i
temperatures, levels and flowrates. The words "above" and "below" shouhi not be used in this context.
3.8 Mechanics Of Style 3.8.1 Spelling Spelling should be based on a current American dictionary. When a dictionary offers a choice of spellings, use the first listed.
i Be consistent in spelling througduut procedures. Several industry teams have varying spellings, such as "startup" and "start-up". Use the spelling most coasnonly used at l
j Duke Power, and use it consistently.
3.8.2 Punctuation Generally, standard American English rules for grammar and punctuation should be used. Refer to Appendix 5 for guidelines on correct punctuation.

3.8.5 Units and Numerals
+
Use the units of measurement that actually appear on the instruments specified.
Use units of measurement familiar to the operator.
Use Arabic numerals unless specific equipment nomenclature contains Roman numerkls.
e Use Arabic whole numbers whenever possible.
+
If whole numbers must be divided, use decimals.
Limit the numbers used in the procedure for parametet' i.idications to one-half of the smallest increment that can be read on the instrument (i.e.,
if an Instrument meter is divided into 50 pound l
increments, then the procedure should not specify actions based on readings of less than 25 pound O
increments).
3.8.6 Tolerances Provide tolerances where appropriate. Give nominal values and ranges in ispediately understood teres, avoiding the need for interpretation. If there is no specific desired value, provide the tolerance as 4
a range.
Example:
Take Turbine to manual control and decrease pressure to 400-410 pSIG by closing governor valves.
1 l
4 Use specific values without ranges when it is desirable to control a carameter as close to a specific value as practical. The operator is 4
expected to use his best judgment based upon current plant conditions and the intent of the procedure step in determining how close to the extet value the parameter actually comes.
Examples:
A.
Throttle CA flow to maintain NR Lvl 38%.
B.
Manually dump steam to reduce "Stm Hdr Pressure" to 1090 pS!G.

PAGE 39 0F 40 3.8.7 Formulas and Calculations p
Avoid the use of formulas and calculations where possible. When calculations are required, they should be as simple as possible, and space should be provided for the calculations.
l 3.9 Location Information Assume that the action occurs in the Control Room for most steps in emergency procedures. For any actions performed outside the Control Room identify only that the actions are outside the Control Room, unless a very infrequently used component is involved.
Identify local, in-plant activities at a specific component as follows:
Example:
Dispatch operator to locally trip Control Rod Drive M/G Sets, e
Identify the location of infreuently used components.
Example:
Dispatch operator to de-energize 0/G Sequencer control power breakers:
e 1EVDA Bkr 6, 0/G 1A (AB-733 BB-46) e 1EV00 Bkr 8, D/G 18 (AB-733, 88-46).
3.10 ENCLOSURES Supplemental information or detailed instructions which would unnecessarily complicate the flow of the procedure should be placed in an enclosure to that procedure. Ordinarily, tables, large lists, and graphs should be incorporated into the procedure as enclosures, hom ver, refer to Section 2.3.3 for use of graphics in the text.
If necessary, assistance may be obtained from the Production Support or Corporate Graphics Arts Department to develop j
suitable graphs for use as enclosures.
When enclosures are used, instruct the user in tne text of the procedure as to the intended use of the enclosure and its location I
i (i.e., enclosure number).
e Format enclosure pages as follows (see example in Appendix 1):
e Enclosure page headings shall be the same as other procedure pages with the exception that the enclosure number and enclosure title will be included directly below tha procedure title.
O Response to Supplement 1 to NUREG-0737.Rev. 4 i
PAGE 40 0F 40 c
+
Enclosures shall be numbered consecutively within a procedure.
Enclosures may use either the two column format of the body or a single column, full page width format.
+
When using graphs, ensure:
Lines on the graph are clearly reproducible.
+
Scales are consistent with the accuracy needeG by the user. Extensive approximation or interpolation should be avoided.
Grid lines on the graph are lighter in weight than the axes and the data being presented.
When using tables, ensure:
6 Each column has a heading.
Include the units for the data in parentheses in the heading. Do not repeat the units ell the way down the column.
{
+
Use the same type style and size as the procedure text.
r Always place horizontal lines above and below the column headings and at the bottom of the table. Place horizontal lines between each entry when needed for 3

McGUIRE NUCLEAR STATION ACRONYi45 AND AB8REVIATIONS a.
NOTE 1:
Those abbreviations indicated by an aste' risk (*) should be used rather than spelling out the word or phase. As a rule, all other words should oe completely spelled out uniess space limitations require abbreviation, or unless the context in which the abbreviation is used makes it easily understood or unless specific component nomencir ure is being used.
NOTE 2:
Pumps ara abbreviated by using the two-letter system designation I
with the word "pump" when the pump name corresponds to the system in thict it is located.
For example, NC Pump (Reactor Coolant-Pump) is in the Reactor Coolant System (NC System). This rule does not hold l
for pumps with names which do not correspond to the system in which they are located.
In this case, use an abbreviation which most logically corresponds to the pump's actual name, taking care not to use an abbrevia. tion that will become confused with a two-letter systen designation.

5 SIMULATOR METHOD OF ERC VALIDATION 1.0 PURPOSE The purpose of this method is to ensure the operational correctness and usability of the ERC by evaluating the operator's performance in order to determine that the System mitigates the consequences of emergency conditions.'
2.0 DESCRIPTION
The simulator isethod of ERC validation can be a complex process due to the need to integrate hardware, software and personnel during relatively short periods of simulator time. This method consists of five phases:
- Planning
- Preparation
- Conductiss the evaluation rial a
- Analyzing results
- Resolving discrepancies 2.1 Planning 2.1.1 Personnel A validation team will be appointed by the OEDD whose l
members are familiar with plant operations, procedures, 1
training and test evaluation methods. The validation team shall be responsible for the following:
1) planning and preparing for the simulator session, and 2)

,; p observing, recording and analyzing operator performance h
during the validation trail in Section 2.3.
~
Operators who are chosen to participate in the validation scenario runs should have a level of training, knowledge and skill which is typical of operators overall.
2.1.2 Sicolator Selection The McGuire Unit 1 plant sg ific simulator will be used for all validation trials.
2.2 Preparation 2.2.1 Select Simulator Scenarios The validation team will select scenarios for implementation based on recommendations of WCAP 10204, ERG Validation Program, and on simulator software OQ considerations.
2.2.2 Delineate Expected Operator Actions After the scenarios have been selected, the validation team will identify the procedures hich should be used by each one. Also, sceps and operator actions will be identified within each procedure which the operator could I
follow in sanaging the emergency event. The delineation of a potential path through the procedures will aid the team in evaluating operator performance of EP's and in detection of discrepancies.
2.2.3 Validation Measurement Techniques An observer checklist and debriefing form, Attachment E, and videotaping (if available) will be used to seasure l

and record operator performance such that all deviations b
can be identified. These techniques will permit the following analysis for each scenario:
- analysis of the operator's ability to control several plant parameters comparison of operator actions to the previously prepared list of expected actions 2.2.4 Plant-Simulator Characteristics In the validation process, the evaluation of the System is being made for the actual plant setting and not for the s htala tor. The validation team will therefore perforia a review contrasting the simulated and actual Control Room setting with respect to the actual Control Room's human factors design, operational design, work-space design and cosusunicating system design. This review will aid the s
team in evaluating whether or not operator performance deviation, occurring in the simulator setting would also occur in the actual plant. Any differences that affect operator performance during the trial will be evaluated per Section 2.4.2.
2.2.5 Crew Familiarization Prior to their session at the simulator, the operating l
(
crews will become familiar with the new procedures during plant training sessions.
In addition, differences which exist between plant and simulator characteristics will be discussed.

2.3 Conducting the Evaluation Tri.t NJ During the initial System triels, as many crews as practical should
' perform each scenario run. A scenario should be performed caly once by any one crew. Each selected r,renario will,be run at least once during the evaluation trials.
For subsequent System trials due to modifications /chantes, at least one operating crew will perform the required scenarios.
~
During the scenario runs, the validation te.*e will observe the operator's actions and completed the observer's portion of Attachment E.
+
2.4 Analyzing Results 2.4.1 Immediately after the' scenario trial is completed, an in-depth debriefing between the validation team and the operating crew will be conducted. The comments of the operators provide one of the most ibportant sources of information for evaluating the. System. Befo e the operators are questioned, they should be allowed to rcake any general comments concerning the scenario run in general or any component of the System in particular.
These comments should be recorded on the debriefing section of Attachment E.
After each operator concludes his remarks, the observers will ask questions based on those outlined in Attachment E and on the deviations which were recorded on their checklist.
l 2.4.2 Evaluate Findings After the debriefing, data gathered from the validation and debriefing must te analysed and classified. The validation team will identify operator performance j
actions which deviated from the actions of the O

hypothetical path determined in Section 2.2.2.
Each of Ny the deviations as well'as other items noted on the Observer Checklist and Debriefing form would be considered to be a potential discrepancy. These items would be examined on a case-by-case bisis to determine if it should be listed as a discrepancy or be deleted from s
R conside. ration. Those' items which are considered to be actual discrepancies will"be documented on the Discrepancy Resolution form (Attachment D) and forwarded s
to the OEDD for resolution.
If no discrepancies are noted, then write NONE on Attachment D for that procedure.
2.5 Resolving Discrepancies The OEDD will review and resolve discrepancies forwarded to his by l
the validation team. Df.screpancies say be due to the deficiencies in the procedures themselves or due to other causes such as deficiencies in the Control Room hardware, training or manpower.
Discrepancies related to procedure deficiencies must be resolved prior to final approval and implementation, i

[//f/8 REAL EVENT REVIEW METHOD OF ERC VALIDATION 1.0 PUPPOSE The purpose of this method is to review feedback from operators who have recently managed an unplanned real emergency event and to review other plant's event reports in order to determine that the Systes sitigates the consequences of emergency conditions.
2.0 DESCRIPTION
2.1 Personnel O
The OEDD will appoint evaluations to conduct the real event review g
method of evaluation who are knowledgeable in plart operations, procedures and training.
2.2 Method A real event review validation conaists of a debriefing conducted by evaluators with plant operators to gather information on the effectiveness of the System during rest conditions. This method of validation is the most effective means of validating the System.
The feedback from operators provides valuable information with respect to the kinds of situations for which the Systes is designed to work.
The debriefing should occur as soon as possible after the emergency event in order to maximize it's effectiveness. The debriefing portion of Attachment E should be completed by the evaluators O

during the interview. Before the operators are questioned, they should be allowed to make comments concerning any System problems they identified during the event. The evaluators will then ask questions as outlined in Attachment E.
2.3 Resolution l
After the debriefing, the evaluators will review the data gathered and determine which items are to be listed as discrepancies and which are to be deleted from consideration. Those items which are considered to be actual Systes problems will be documented on the Discrepancy Resolution form (Attschment D) and forwarded to the OEDD for resolution.
l Discrepancies which are found in the System as a result of the real event review validation will be reviewed and resolved by the OEDD.
l Any resolutions requiring changes to the EP's will be implemented in a timely manner after undergoing the EP verification process if applicable. Any rt; solutions requiring Control Room changes, training or operator staffing will be forwarded to the appropriate individual for completion.
