INTRODUCTICN 1.1 PURPOSE
'1he purpose of this Procedures Generation Package (PGP) is to describe the describe the emergency operating procedures (EOPs) upgrade at Millstone Unit 2.
1.2 SCOPE
'this doctanent was developed in response to Supplement 1 to NUREG-0737, Item 7.2b, page 15.
1.3 BACKGROUND
Iten 1.C.1 of NUREG-0737 requires that E0Ps be upgraded based on the lessons learned fran the 'Ihree Mile Island accident.
It specifies that operators be provided with directions to mitigate the consequences of a broad range of accidents and equipnent failures, and that these directions be function, as well as event oriented.-
'1 hey should provide the operator with guidance on how to verify the adequacy of certain safety functions, and how to restore and maintain those functions when they are %aded.
In this manner, the operator will not have to inmediately diagnose an event, such as a small loss of primary coolant event, to maintain the plant in a safe configuration.
I NNBCo personnel have been actively participating for several. years in a Ctzbustion Engineering Owner's Group (CEOG) program to develop generic Bnergency Procedure Guidelines (EPGs).
'Ihis program has resulted in the analysis and reanalyses of many transients and accidents.
'Ihe 1
results of these analyses form the bases for the generic EPGs.
'1he generic EPGs were subnitted to the NRC Staff in a report entitled, "Ocabustion Engineering Bnergency Procedure Guidelines,"
CEN-152, Revision 1, dated Novetber 22, 1982.
'1his report contains the final emergency procedure guidelines, as description of the guideline characteristics and features, the methodology to develop and validate the guidelines, and information on inglenentation of the guidelines.
Reference 3.2 provided NRC Staff acceptance of the CEOG EPGs for brplementation in plant-specific Bnergency Pperating Procedures (EOPs) and identified technical and administrative issues which will require resolution in the future.
Using the generic EPGs contained in CEN-152, Revision 1 (Reference 3.3),
and guidance developed by the industry Bnergency Operating Procedures Itnplementation Assistance (EOPIA) Review Group EQPs will be upgaded via a four phase pr@uuu.
'Ihese phases are:
(1) in preparation of a writer's guide and changes to the CEOG EPGs specifically for Millstone Unit No.
2, (2) procedure writing and verification, (3) validation, and (4) training. An overview of the ET inplementation process is depicted by Figure 4.1.

StMERY DESCRIPTIGI CF PROGRAM 1
j
'Ihis section provides a sunnary of the program for upgrading anergency I
Operating Procedures at Millstone Unit 2 based on Cornbustion Engineering Owner's Group (CEOG) guidelines.
i-2.1 INITIAL CCNSIDERATICES a.
Procedure Network ETs are only one of the many types of instructions within the plant's procedure network system.
'Iheir relationship to each other and other plant procedures is called the procedures network.
'1his network is considered by the Project Team during E0P upgrade to ensure continuity of the E0Ps with the %rting plant and systen pn> *bres.
Where necessary, charx,es to existing procedures are m Mei and processed as part of this program.
Ebr purposes of ECPs, an emergency event is distinguished from other plant operations by virtue of its severity:
it should be suffick_ntly severe that a reactor trip is either activated or required innediately to properly mitigate the event.
'Ihere is
4 f)
U another less severe class of events for which a reactor trip is not required, but if left unattended could eventually challenge safety functions.
A new set of procedures will be created to address this later class, called abnormal operating procedures.
Figure 4.2 depicts the distinction between emergency and abnormal procedures. 'Ihis procedure set will include some procedures which were previously designated at emergency procedures.
Events that are more serious than normal transient but not severe enough to warrant an 4 M _iate Reactor Shutdown will be included here.
b.
Shift Staffing
'Ihe EOPs must be structured so that the number of people required to carry out the specified actions do not exceed the minimum shift staffing required by the Technical Specifications.
The following staffing level is assumed in the EOP Upgrade Program:
One Shift Supervisor (SRO/STA qualified)
Che Supervising Control Operator (SRO)
'Iko Control Operator (RO)
Three Plant Equipnent Operators One HP Technician One Chemistry Technician and other anergency Plan personnel as appropriate c.
Plant Modifications As part of the EOP Upgrade Program, it is necessary to ensure that the EOPs reflect plant modifications that are made up to and during the 1983 outage.
2.2 PROJECT TEAM The new EOPs are prepared and implemented by a project team called the Millstone 2 EOP Upgrade Project Team. 'Ihe organization of the project team is depicted below.
lO
0 Millstone 2 Superintendent Millstone 2 Ops Supervisor Project Coordinator Clerical NUSGo Project Engineer Licensed Training C-E NUSGo Operators Personnel Engineer Technical Assistance 2.3 PIANT SPECIFIC TECHNICAL GUIDELINES Because of the similarity between Millstone Unit 2 and the generic plant used in the Ocmbustion Engineering Owners' Group (CEOG) guidelines, Millstone Unit 2 will use the generic guidelines to upgrade existing plant emergency procedures.
This section describes the process that will be used.
The CEOG EPGs and the other source documents indicated below constitute the plant specific technical guidelines required by Peference 3.1.
O
a g
(3
~()
a.
Source nev,- nts EOP writers will use the following source documents to prepare upgraded EOPs.
EOP Writers Guide CEOG Bnergency Procedure Guidelines Technical Specifications Existing Bnergency Procedures FSAR Licensing cmmitment letters related to EOPs Idministrative Control Procedures b.
Draft EOPs
'1he EOP writer will review the source documents and then construct draft EOPs using the following additional guidance.
If it is determined that a generic step is empatible with Millstone 2, then the step will be copied into the EOPs using the appropriate format instruction.
When a generic step requires a plant specific value, it will be determined and put into the EOP.
When a generic step indicates the need for plant-specific details, then the information will be added to the EOPs.
When the generic guidelines fail to address systems or actions that are unique to Millstone 2, then steps will be included to enempass the necessary actions.
If a generic step specifies an action that cannot be performed at Millstone Unit 2, then the ster will be deleted or modified.
O
~-
- /
Generic steps will be reworded to conform to Millstone Unit 2 standard terminology.
Generic steps may be rearranged to streamline the procedure provided the technical intent remains unchanged.
c.
Final E0Ps After the draft E0Ps are prepared, verification and validation processes will be performed as described in the following sec-tions.
At the conclusion of the verification and validation, operators are trained and the E0Ps will be approved and inplement-ed.
Revisions will be processed as required in accordance with achinistrative control procedures.
2.4 WRITERS GUIDE FOR EOPs A writers guide for EOPs is a plant-specific document that provides instructions on writing EOPs.
In addition to establishing sound procedure writing principles, the guide helps to. prcnote consistency anong all EOPs and their revisions, independent of the nunber of ECP writers.
He Millstone Unit 2 Writers Guide for Bnergency Operating Procedures is based on the industry Av - nt Bnergency Operating Procedures Writing Guideline (INPO 82-017), developed by the anergency Operating Procedures Inplementation Assistance (BOPIA) Review Group and published by INPO.
His writers guide will be added to W-3.02, Station Procedures and Forms, as Attaclunent B when the EOPs are inplemented.
Se concepts presented in the writer's guide were closely followed during the preparation of upgraded EOPs.
The Writers Guide will be revised, as necessary, based on feedback frczn procedure writing experience validation, training, and operating experience.
,~.
(vl 2.5 EOP VERIFICATICN PROGRAM EOP verification is the evaluation performed to confirm the written correctness of the procedure and to ensure that applicable generic and plant-specific technical information has been incorporated properly.
'Ihis evaluation also checks that the human factors aspects presented in the writers guide have been applied.
Initial EOP verification is accmplished by cmpleting all the elements described below, a.
qerations Feview
'Ihe EOP's will be made available to Department Heads, Training, and each operations shift for review.
'Ihe purpose of this review is to give the upgraded draft EOPs the broadest possible exposure to the licensed operators and staff prior to subsequent training and inplementation.
'Ihis review consists of providing copies of the draft upgraded EOPs to the licensed operator requalification
<w (j
classes and training staff for their discussion and cmment.
A review /cament sheet will be provided to collect and respond to cm ments. Refer to Figure 4.3.
b.
EOP Verification Checklist An EOP verification checklist is used to ensure that the EOP conform to certain human factors principles and represent a degree of consistency in presentation of the written material.
Figure 4.4 provides an EOP verification checklist. 'Ihe checklist is used as an aid to the EOP reviewer in performing his review.
c.
Table Top Peview Each EOP is thoroughly discussed by a group of operators, engineers and trainers.
Each EOP is thoroughly discussed by the EOP project team with the purpose of coming to a consensus on the adequacy and accuracy of the EOP. The EOP project team consisted of licensed plant operators, engineers and licensed training staff l ]
personnel.
q d.
Control Rom Walkthrough Each EOP will be walked through the control rom to ensure otxtpatibility with existing control rom indications.
e.
Plant Operations Review Comnittee (PORC)
'Ihe EOPs will be reviewed and approved by the PORC in accordance with Administrative Control Procedure, ACP-QA-1.04, PORC.
f.
Safety Analysis Review Selected EOPs will be reviewed by Northeast Utilities Safety Analysis Branch in accordance with Nuclear Engineering and Operations Procedure NEO 3.12, Safety Evaluations.
g.
Resolution of Discrepancies Any discrepancy is corrected and incorporated in the next draft of the EOP. h project coordinator is responsible for ensuring that these are resolved.
He reports directly to the Operation
(
Supervisor.
2.6 EOP VALIDATICN PROGRAM
'Ihe objective of EOP validation is to de.termine that the actions spec-ified in the procedure can be performed by the operator to manage emergency conditions effectively.
The methodology for EOP validation utilizes present available methods.
h EOP validation will evaluate the operators' ability to manage emergency conditions using the EOPs.
'Ihe validation program described here outlines the process used to confirm the actions specified in the EOPs can be performed by plant operators to manage mergency conditions.
'Ihe upgraded EOP Validation consisted of two phases, Initial Validation of Draft Upgraded EOPs and Final Operator Evaluation.

,~(j Initial Validation of Draft Upgraded EOPS
'Ihis part of the validation program had the following objectives:
'Ib identify those areas of the draft upgraded EOPs that are difficult for the operating shift to use or understand.
'Ib provide feedback fran the operating shift personnel.
To identify upgraded EOP training needs. 'Ihese needs are those of operators who had been trained on existing EOPs and had not been trained on the draft upgraded EOPs.
To demonstrate that the draft upgraded EOPs can be used to manage emergency conditions effectively.
'lhe following methods were used:
p k
Designate Observe / Review Team and Operator Personnel The Project Ooordinator will designate personnel to participate in the initial validation of draft upgraded EOPs.
'Ihe EOPs will be exercised by an operations crew consisting of a Shift Supervisor (SRO and STA qualified), a Supervising Control Operator (SRO) a Primary Plant Operator and a Saoondary Plant Operator (Both RO licensed).
The exercises were observed by mmbers of the EOP Project Team and with additional support frun two staff SRO licensed personnel (both not directly involved with the upgraded EOP program).
Selected Soenario selection Scenarios were selected with the assistance to the CE sinulator instructor criteria for selection included:
a.
Exercise as much of each draft upgraded EOP as possible.
O
b.
Remain within the operating capabilities of the sinulator, c.
Exercise the draft upgraded EOPs on two events at the same time.
For exanple Ioss of Primary Coolant and Steam Generator Tube Rupture, Excess Steam Demand and Steam Generator Tube Rupture, etc.
Performance Review At the end of each scenario a review session was held to gather cmments.
'Ihese cmments were red-lined directly onto the draft upgraded EOPs. Additional notes were taken as to training needs.
After the validation session, these cmments are resolved by the EOP Project Team.
Final Operator EOP Evaluation As part of the training program more extensive sinulator exercise of the updated EOPs takes place.
During the training exercises as f')
additional connents/ concerns were raised, they were fed back to the EOP project team to be considered and included, if appropriate, in the inplemented version of the upgraded EOPs.
During the final training session the Operators are evaluated on their ability to use the procedures to successfully manage emergency conditions effectively.
'Ihis evaluation is made by the training department personnel and an additional staff license and is documented.
(see Figure 4.5)
Simulator - Plant Differences Differences between the design of CE Training Sinulator and the Millstone 2 Control Roan are to be discussed at the beginning of the validation session.
For tho,se sections of the upgraded EOPs that address areas different frcm the sinulator, the control rocn walk-through and table top reviw provides the method by which the upgraded EDP is judged usable.
(
Final EOP Revisions Specific major revision to the upgraded EOPs occurring after inplementation may require additional verification / validation.
%e Operations Supervisor will determine the need for and scope of any follow-up V&V efforts.
2.7 EOP TRAINING PROGRAM We EDP format requires that the operator have a significant knowledge level based on experience and specific training on the use of the E0Ps.
As part of the EOP Upgrade Project, a bases document will be developed for each E0P which includes specific information which nust be learned in order to use the EOPs.
We ba s includes information fran the CEOG EPG training material nodified with Millstone Unit 2 specific information.
We bases will be primary reference for developnent of training materials.
s
%e training program described herein is emprised of both classrom and sinulator training.
The training program has four major objectives:
(1)
'Ib enable the operator to understand the structure and format of all EOPs.
(2)
'Ib enable the operator to understand the technical bases of all E0Ps.
(3)
'Ib enable the operator to understand how all E0Ps ensure that safety functions are satisfied.
(4)
'Ib give the operator experience in using all EOPs under sinulated control rom conditions.
O
O The training process can be divided into the following areas.
In each V
area training is presented to the operations staff one shift at a time.
'Ihis ernphasizes the team approach of each shift and reinforces operator roles.
a.
Awareness and Involvement in the Upgrade Process During operator requalification training in 1983 the EOP upgrade program progress will be discucsed and draft procedures will be reviewed and critiqued.
'Ihis approach of using the training shift to get operator review and feedback as well as training on the upgraded EOPs kept the license personnel involved in the process of inplementing and maintaining effective EOPs.
b.
Individual Study and Review Prior to classrowa presentation, each EOP will be reviewed by the licensed operator.
c.
Classrom Presentation and Discussion Instruction will be given on:
a.
Use of the new format b.
Standard post trip actions c.
Each event specific EOP d.
When and how to use the functional EOP O
[)
d.
Sinulator Instruction V
Use of the sinulator will provide each operator the " hands on" experience of using all the EOP under control rom operating conditions.
his allows the operator to observe the effects of various actions and non-actions.
Initial upgraded EOP training was performed on the C-E training sinulator.
Differences between the sinulator and MP2 are discussed at the beginning of each sinulator portion of the training.
NNECo is building plant specific sinulators to be used in future operator training.
Scenarios are selected which provided the widest possible exposure of the operator to the E0Ps. Scenarios are manipulated to provide the maximum EOP training benefit.
e.
Examination Tests will be administered to check that the necessary information P
has been learned. his will include:
(
i.
Written examination at the conclusion of classrom presentation.
ii. Operating evaluation at the conclusion of the sinulator instruction.
2.8 DOCUMENT CNTROL/REVISICN
%e process followed in revising, reviewing, and approving the EOPs and supporting documents nust be clearly defined.
We process is not unique to EOPs, and administrative control procedures are already established.
However, the process will be reviewed and clarified as necessary to assure that future information needed in the E0Ps is correctly incorporated.

3.2 PROCEDURE ORGANIZATION Each E0P will contain the following sections:
Section 1 PURPOSE - The purpose will define what the procedure will accomplish.
Section 2 ENTRY CONDITIONS - The entry conditions will give those conditions for which the procedure will be used..These give the operator a means of confirming that he has chosen the appropriate procedure for particular emergency conditions.
This section will denote if all or some of the conditions are required for use of the procedure.
Section 3 OPERATOR INSTRUCTIONS - These actions are taken to stop further degradation of existing conditions, to initiate desirable effects and to allow the operator to evaluate the situations.
Only the Standard Post Trip Actions are immediate and must be available from memory.
The rest of the E0P's contain specific
(
subsequent operator actions dependent on existing plant conditions after completion of the Standard Post Trip Actions.
l Section 4 FIGURES - Contains of all figures used in the E0Ps.
3.3 SECTION NUMBERING Section numbering is required to provide easy identification of l
the instruction steps of the procedure.
Exhibits 3, 4 and 5 are used as examples of the desired section numbering system.

WRITING PROCEDURES v
4.1 GENERAL INSTRUCTIONS Procedures must be written with the detail sufficient to support the user's needs.
This requires the assumption of a minimum knowledge and experience level.
This level is defined to be an operator that has recently received a reactor operator's license on Millstone Unit 2.
It is important to keep this in mind when deciding on the detail level of l
procedural steps, cautions, notes and figures.
Avoiding too much detail is important in order to minimize errors and allow for a timely response.
The following general rules are to be followed:
Instruction steps should deal with only one idea.
Instruction steps should be sentence fragments.
Notes and cautions should be in simple but complete sentences.
O Complex evolutions should be prescribed in a series of u
steps, with each step made as simple as possible.
Objects of operator actions should be specifically stated.
Space must be provided for operator checkoff prior to each instruction step.
Minimal indentation to give best use of space and is used for clarity only, m
Limits should be expressed in numbers whenever possible (refer to Subsection 5.5).
Mandatory sequence of steps is assumed unless otherwise stated.
Identification of components and parts should be identified by common usage terminology.
Expected results of routine tasks need not be stated.
System response time associated with performance of the instruction is provided in notes when this information is helpful.
o V
Pagn 6 Use a Caution to' describe the conditions that will introduce instrument error.
Instrumentation values should be compatible with the
-ability to read the instrument.
Do not require a mathematical calculation to convert to a tolerance band.
'Use a tolerance band.
Units of measure are consistent with the instrument.
Use the verb verify when the user is to perform a verification step.
Specify precisely what is to be verified.
If a step is to be performed continuously or periodically, specific detail must be provided as to the time interval required.
Recurrent steps should not be used.
An example of a recurrent step is " Check CST level every 30 minutes".
Alternative steps can be provided for in the contingency action column.
Alternative steps should be listed in order of preference and separated by "or".
The use of required concurrent steps should be avoided.
If the use of concurrent steps is necessary, specific guidance must be provided.
These steps should not be
.beyond the control room staffs capability.
E0P steps should be written considering the normal plant shift' staff levels as specified by Technical i
Specifications and the station emergency plan.
The E0Ps should be. structured so that operator. roles specified in the E0Ps are consistent with pre established leadership roles and divisions of responsibilities that exist during normal plant operation.
The action steps should be structured so as to minimize physical conflicts between personnel and to minimize the amount of movement needed for carrying out the steps.
The action steps should be structured to avoid their unintentional duplication by operators.
Page 7 l9 4.2 WRITING INSTRUCTION STEPS E0P's will be written in a two column format.
Exhibit 4 provides an example. The instructions shall be in short, concise and easily understood statements.
Instructions written in fragments as opposed to complete sentences provide the best use of space and allow for clearest possible understanding.
Action steps should be wholly contained on a page.
4.2.1 Instructions This column provides the expected operator actions.
Begin each step with the action verb when logic terms are not required.'
Include the location of the parameter or control being used in parenthesis.
4.2.2 Contingency Actions This column provide actions for the operator to take only.if the instruction column step cannot be performed.
This action will most likely require the
/
manual initiation of a system that is expected to operate automatically.
Other actions may include:
1)
' reference to an A0P or OP 2) reference to another E0P 3) reference to outside assistance from the TSC or EOF.
4)
Continue with the procedure 5)
Not Applicable 4.3 USE OF LOGIC TERMS The logic terms H, When, and Then, are often necessary to describe precisely a set of conditions or sequence of actions.
When logic statements are used, logic terms will be emphasized so that all the conditions are clear to the operator.
Emphasis will be achieved by capitalizing the first letter and underlining.
10 V
l
?
[
Paga 8 The use of "and" and "or" within the same action should be I
minimized. When "and" and "or" are used together, the action should not be confusing or ambiguous.
Use other logic terms as follows:
When attention should be called to combinations of conditions, the word "and" shall be placed between the description of each condition.
The word "and" shall not be used to join more than two conditions.
If more than two conditions need to be joined, a list format shall be used and the operator directed to do all of them.
The word "or" shall be used when calling attention to alternative combinations of conditions.
The use of the word "or" shall always be in the inclusive sense.
To specify the exclusive "or" the following may be used:
"either A E B but not both."
When action steps are contingent upon certain conditions or combinations of conditions, the step shall begin with the words H or When followed by a description of the condition or conditions (the antecedent), a comma, the word Then, followed by the action to be taken (the consequent). When is used for an expected condition. E is used for possible condition.
Then shall not be used at the end of an action step to instruct the operator to perform the next step. It adds confusion by running actions together, 4.4 CAUTIONS AND NOTES Cautions can be considered in two fundamental categories:
those that apply to the entire procedure and those that apply OG
i e
Paga 9 (m
to a portion of the procedure.
Those that apply to the entire procedure are called precautions and are covered in operator training.
Those that apply to a portion of a procedure are called cautions and are placed immediately before the portion of the procedure to which they apply.
Cautions are to extend across the entire page and are bordered top and bottom by solid horizontal lines.
This placement of cautions ensures that the procedure user observes the caution before performing the step.
A caution shall not be used instead of an instructional step and it cannot direct an action.
It should be used to denote a potential hazard to equipment or personnel associated with or consequent to the subsequent instructional step.
If additional information other than cautions is necessary to support an action instruction, a note should be used.
A note should present information only, not instructions, and should extend across the entire page.
See Exhibit 4 for examples of
,O) caution and note format.
Q Specific rules for cautions and notes:
Never continue a caution or note from one page to the next.
Cautions are emphasized by their full page width, a solid horizontal line top and bottom and additional space top and bottom.
Caution-and notes should be placed on the same page as the step they address.
Notes are emphasized by their full page width and added space top and bottom.
If two or more separate cautions are together the bottom Il horizontal line is below the last caution only.
The word
\\
t V
CAUTION is only present lefore the first caution.
Paga 10
{J The separate cautions will be identified by number.
(Refer to Exhibit 4).
The heading CAUTION or NOTE is always centered, capitalized and underlined.
4.5 CALCULATIONS Mathematical calculations should be avoided in E0Ps.
A chart, graph, or other operator aid should be used when a value has to be determined.
4.6 USE OF UNDERLINING Underlining will be used for emphasis, logic terms, caution, note, section headings and column headings.
Underline only where appropriate for required emphasis.
4.7 REFERENCING AND BRANCHING TO OTHER PROCEDURES OR STEPS i
Referencing implies that a procedure or steps of a procedure will be 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 because it causes confusion.
To minimize potential operator confusion, branching will be used when the operator is to leave one procedure and use another procedure.
Use the words "go to" when the operator is to leave the procedure and not return unless directed.
The words " refer to" will be used when the user is to use another procedure concurrently with the original procedure.
See exhibit 6 for examples.

4.8 COMPONENT IDENTIFICATION With respect to identification of components, use the following guidelines:
Equipment, controls, and displays will be identified in common usage terms.
These terms may not always match engraved names on panels but must be clear and precise.
Where the engraved names and numbers are specifically used the engraving should be quoted verbatim and enclosed in quotation marks.
If the component is seldom used, difficult to find, or may be corfused with another component, then location information should be given in parentheses.
4.9 LEVEL OF DETAIL
()
Too much detail in E0Ps should be avoided in the interest of reading and comprehension.
The level of detail required is that necessary for an operator that has recently received a Reactor Operators license on Millstone Unit 2.
To assist in determining the level of E0P detail, the following general rules apply.
For control circuitry that executes an entire function upon actuation of the control switch, the action verb appropriate to the component suffices without further amplification of how to manipulate the control device.
Example:
Open generator field breaker.
Guidance for dealing with abnormal results need not be l
prescribed within procedural steps when it is a matter of standard practice.
For example, observation of noise, t
vibration, erratic flow, or discharge pressure need not be specified by steps that start pumps.
i
Paga 12 4.10 PRINTED OPERATOR AIDS When information is presented using graphs, charts, tables, and l
figures, these aids must be self-explanatory, legible, and readable under the expected conditions of use within the reading precision of the operator.
4.10.1 Units of Measure Units of measure on figures, tables, and attachments should be given for numerical values which represent measurement data or calculating results.
Use a virgule (slant line) instead of "per" Examples:
ft/sec, 1bs/hr.
See Table 1 for preferred abbreviations.
4.10.2 Titles and Headinas Capitalization should be used for references to tables and figures, titles of tables and figures within text material, and column headings within a table.
O 4.10.3 Fiaure, Table, and Attachment Numberina Sequential arabic numbers will be assigned to figures, tables, and attachments in separate series.
The seqence should correspond with the order of their reference in the text.
The symbol "#" and abbreviation "No." are unnecessary and should not be used.
The number alone suffices.
Example:
Figure 4.1 Page identification for attachments should consist of a block of information that identifies (1) procedure number, (2) procedure revision, (3) attachment number, (4) page number.
Page numbering of attachments should meet the requirements of Subsection 2.5.

\\
()
4.10.4 Printed operator aids are included in the E0P folder for use by the operator as he is using the E0P.
4.10.5 Graph axes should be labeled with the parameter to be read.
Units must be equivalent to control board instrumentation and values presented in such a manner as so the information can be determined with the necessary accuracy.
5.
MECHANICS OF STYLE 5.1 SPELLING Spelling should be consistent with modern usage. When a choice of spelling is offered by a dictionary, the first spelling should be used.
5.2 HYPHENATION Hyphens are used between elements of a compound word when usage calls for it.
The following rules should be followed for
/
\\
! )
hyphenation.
When doubt exists, the compound word should be restructured to avoid hypenation.
Hyphens should be used in the following circumstances:
a.
in compounds with "self"; Examples: self-contained, self-lubricated, b.
when the last letter of the first word is the same vowel as the first letter of the second word; as an alternative, two words may be used:
Example:
fire-escape or fire escape (preferred).
c.
when misleading or awkward consonants would result by joinng the words; Example:
bell-like d.
when a letter is linked with a noun; Examples:
X-ray, 0-ring, U-bolt, I-beam.
e.
to separate chemical elements and their atomic
(
)
weight; Examples:
Uranium-235 or U-235
Pag 3 14 5.3 PUNCTUATION Punctuation should be used only when necessary to aid reading and prevent misunderstanding.
Word order should be selected to require a minimum of punctuation. When extensive punctuation is necessary for clarity, the sentence should be rewritten and possibly made into several sentences.
Punctuation will be in accordance with the following rules.
5.3.1 BRACKETS Do not use brackets.
5.3.2 COLON Do not use colons.
5.3.3 COMMA Minimize use of commas.
Use of many commas is a sign the instruction is too complex and needs to be rewritten.
After conditional phrases for clarity and ease of t
reading, use a comma.
Example: When level decreases to 60 inches, Then start pump....
5.3.4 PARENTHESES Parentheses will be used to indicate panel numbers locations, or other information judged to be suitable for parenthetical inclusions, such as an alternate action for a contingency step.
5.3.5 PERIOD Use a period at the end of complete sentences and for indicating the decimal place in numbers.
5.4 VOCABULARY Words used in procedures should convey precise understanding to the operator.
Use simple words.
Simple words are usually short words of (a) few syllables and common use.
c s.
Paga 15
.Use the common words that are normally used in control room communications.
Use words that are concrete rather than vague, specific rather than general, familiar rather than formal, precise rather than blanket and use their meaning consistantly.
Words with specific meaning should be used.
Acceptable verbs are listed in Table 2.
' Avoid the use of pronouns 5.5 NUMBERICAL VALUES The use of numerical values should be consistent with the following rules:
Arabic numerals should be used.
For numbers less than unity, the decimal point will be
. preceded by a zero.
For example: 0.1 l
The number of significant digits should be equal to the number.of significant digits available from the display and the reading precision of the operator.
Acceptance values should be specified in such a way that addition and subtraction by the user is avoided. This can generally be done by stating acceptance values as limits.
Example:
580* to 600*F.
Do not write out values.
. (o e
Pagn 16 r~3
[Q 5.6 ABBREVIATIONS, LETTER SYMBOLS, AND ACRONYMS The use of abbreviations and acronyms should be used when they are the common use terms in the control.roca by operation personnel.
Acceptable abbreviations and acronyms are provided by Table 1.
Capitalization of abbreviation should be uniform.
If the abbreviation is comprised of lowercase letters, it should appear in lowercase in a title or heading. The period should be omitted in abbreviations except in cases where the omission 0" '
would result in confusion.
letter symbols may be used to represent operations, quantities, elements, relations, and qualities.
