1.0 INTRODUCTION
1.1 PURPOSE The purpose of this document is to provide administrative and technical guidance on the preparation of E0Ps.
1.2 SCOPE This writers guide applies to the writing of all emergency operating procedures (EOPs).
2.0 E0P DESIGNATION AND NUMBERING E0Ps are procedures that govern the plant operation during emergency conditions and specify operator actions to be taken to return the plant to a stable condition.
Each plant procedure shall be uniquely identified. This identification permits essy administration of the process of procedure preparation, review, revision, distribution and operator use.
2.1 PROCEDURE DESIGNATION Designation of the emergency operating procedure designator shall be E0P.
2.2 PROCEDURE NUMBERING A sequential number will follow the procedure designator and will consist of two digite.
Example: EOP 05 Sequence Number Procedure Designator 2.3 REVISION NUMBERING AND DESIGNATION Two digits following the abbreviation "Rev" will be used to designate the revision level of the Emergency Operating Procedure.
Example: Rev 01 Revision Level Abbreviation 1

NLO1-RRF13-PGP
BIG ROCK POINT NUCLEAR PLANT SPECIFIC WRITERS GUIDE FOR ENERGENCY OPERATING PROCEDURES 3.0 FORMAT The following format is to be applied consistently for all E0Ps.
3.1 FLOW CHART FORMAT A flow chart format will be used. Action flow will be from the top to the bottom of a chart. A sample page format is presented in Figure 1.
3.2 PROCEDURE ORGANIZATION Each E0P flow chart will contain the following:
1.
Title - The title will be stated at the top of the page for operator association with the entry conditions.
2.
Entry Conditions - The entry conditions will include only those alarms, indications, operating conditions, automatic system actions or other unique symptoms that the operator is to use in deciding to use the_ procedure.
Entry conditions will not be a requirement to a. contingency as entry into a contingency is directed by a step (s) from a particular E0P.
3.
Operator Actions - The operator actions will be short, concise, identifiable instructions that give appropriate directions to the user.

BIG ROCK POINT NUCLEAR PLANT SPECIFIC WRITERS GUIDE FOR EMERGENCY OPERATING PROCEDURES 3.3 SECTION HEADING DESIGNATION Section heading designation shall be made for each section of operator actions that is performed within that particular emergency operating procedure. These will be shortened by abbreviation to assist in numbering of steps.
Example: Reactor Level Control, Reactor Pressure Control and Reactor Power Control are all sections within the Reactor Controls Emergency Operating Procedure.
Section Headina Abbreviation Reactor Level Control -
RC/L Reactor Pressure Control -
RC/P Reactor Power Control -
RC/Q 3.4 NUMBERING OF STEPS Numbering of steps shall be made by the use of abbreviated letters derived from the appropriate section heading and Arabic numerals.
Example: Section Headina Reactor Level Control (RC/L)
RC/L-1 Step i RC/L-2 Step 2 RC/L-3 Step 3 Contingencies will use the capital letter C and an Arabic numeral corresponding to the appropriate contingency. These will be followed by a hyphen and an Arabic numeral corresponding to each step.
Example: C1-1 Step Number Contingency Number Designates Contingency 4.0 WRITING INSTRUCTIONAL STEPS 4.1 INSTRUCTION STEP LENGTH AND CONTENT Instruction steps will be concise and precise. Conciseness denotes brevity; preciseness means exactly defined. Thus, instructions should be short and exact. This is easily stated, but not so easily achieved. General rules to be used in meeting these objectives are as follows:
4 Rev 0 NLOl-RRF13-PGP
BIG ROCK POINT NUCLEAR PLANT SPECIFIC WRITERS GUIDE FOR EMERGENCY OPERATING PROCEDURES Instruction steps should deal with only one idea.
Short, simple sentences should be used in preference to long, compound or complex sentences.
Complex evolutions should be prescribed in a series of steps, with each step made as simple as practicable.
Objects of operator actions should be specifically stated.
This includes identification of exactly what is to be done, j
i and to what.
i Limits should be expressed quantitatively whenever possible.
1 3
Mandatory sequence of steps is assumed unless otherwise stated.
1 Identification of components and parts should be complete.
}
Instruction content should be written to communicate to the user.
]
Expected results of routine tasks need not be stated.
t When anticipated system response may adversely affect instrument indications, describe the conditions that will likely introduce instrument error and means of determining if instrument error j
has occurred by using a NOTE.
4.2 USE OF LOGIC TERMS The logic terms AND, OR, NOT, IF, IF NOT, 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 highlighted so that all the conditions are clear to the operator.
Emphasis will be achieved by using capitalisation and underlining.
All letters of the logic terms shall be capitalized and the words will be underlined.
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 OR shall be used when calling attention to alternative combinations of conditions.
When action steps are contingent upon certain conditions or combinations of conditions, the step shall begin with the words IF or WHEN followed by a description of the condition or 5
Rev 0 NL01-RRF13-PGP
BIG ROCK POINT NUCLEAR PLANT SPECIFIC WRITERS GUIDE FOR EMERGENCY OPERATING PROCEDURES conditions (the antecedent), a comma, the word THEN followed by the action to be taken (the consequent).
THEN shall not be used at the end of an action step to instruct the operator to perform the next step because it runs actions together.
4.3 USE OF CAUTIONARY INFORMATION AND NOTES Cautionary information can be considered in two fundamental categories: those that apply to the entire procedure and those that apply to a portion or a specific step 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 procedural steps to which they apply.
Caution symbol designation shall be in bold print and highlighted as shown in the Example CAUTION. This placement of cautions helpe ensure that the procedure user observes the caution before performing the step. A caution cannot be used instead of an instructional step. It should be used to denote a potential hasard 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 instruction, and should be attached beside the step to the right hand side.
The following example illustrates these instructions.

+20" O -aa*

The numerals inside the symbols will correspond to the appropriate CAUTION or NOTE contained in the Caution and Note Key.
6 Rev 0 l
NLOL-RRF13-PGP
BIG ROCK POINT NUCLEAR PLANT SPECIFIC WRITERS GUIDE FOR' EMERGENCY OPERATING PROCEDURES 4.4 CALCULATIONS Mathematical calculations should be avoided in E0Ps.
If a value has to be determined in order to perform a procedural step, a chart or graph should be used or referenced whenever possible.
4.5 REFERENCING AND BRANCHING TO OTHER PROCEDURES OR STEPS Referencing implies that an additional procedure or additional steps 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 minimised.
To minimise potential operator confusion, branching will be used I
when the operator is to leave one procedure or step and use another procedure or step. Use the key words "go to".
Therefore.
the operator will know to leave the present step and not return until directed.
[
4.6 COMPONENT IDENTIFICATION
[
i' With respect to identification of components, the following rules are to be followed:
Equipment, controls and displays will be identified in operator language (co m o usage) terms. These terms may not always match engraved names on panels but will be complete.
t The names of plant system titles are emphasised by initial capitalisation. When the word " system"-is deleted from the title because of brevity and is understood because of the context, the title is also emphasised by initial capitalisation.
4.7 LEVEL OF DETAIL Too much detail in E0Ps should be avoided in the interest of being able to effectively execute the instructions in a timely manner.
l The level of detail required is the detail that a newly trained and licensed operator would desire during an seersency condition.
To assist in determining the level of EOF detail, the following general rules apply For each control with a number engraved on the control panel placard, the number s.'uld be included in parentheses within the instructional steps for example. " Start Reactor Recirc Pump #1".
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 7
Rev 0 NLOl-RAF13-PGP
r BIG ROCK POINT NUCLEAR PLANT SPECIFIC WRITERS GUIDE FOR EMERGENCY OPERATING PROCEDURES to manipulate the control device; for example, "Open Backup Containment Spray Valve MO-7068." Recommended action verbs are as follows:
For power-driven rotating equipment, use " Start, Stop".
a.
b.
For valves, use "Open, Close. Throttle Open, Throttle Close. Throttle".
c.
For power distribution breakers, use " Synchronize and close, Trip".
Standard practices for observing for abnormal results need not be prescribed within procedural steps. For example, observation of noise, vibration, erratic flow, or discharge pressure need not be specified by steps that start pumps.
4.8 PRINTED OPERATOR AIDS When information is presented using graphs, charts, tables and figures, these sids must be self-explanatory, legible and readable under the expected conditions of use and within the reading precision of the operator.
5.0 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 PUNCTUATION Punctuation should be used only as necessary to aid reading and prevent sisunderstanding. Word order should be selected to require a minimum of punctuation. When extensive punctuation is necessary for clarity, the sentence should be rewritten and possible made into several sentences. Punctuation should be in accordance with the following rules.
5.2.1 Colon Use a colon to indicate that a list of items is to follow, for examplet Restore cooling flow as follows:
5.2.2 Comma Use of many commas is a sign the instruction is too complex and needs to be rewritten. Therefore, evaluate the number of commas to ensure the instruction is not too complex.
8 Rev 0 NLO1-RRF13-PGP
BIG ROCK POINT NUCLEAR PLANT SPECIFIC WRITERS GUIDE FOR EMERGENCY OPERATING PROCEDURES Use a comma after conditional phrases for clarity and ease of reading. Example: WHEN level decreases to 60 inches, THEN start pump...
5.2.3 Parentheses Parentheses shall be used to indicate alternative items in a procedure, instruction or equipment numbers.
5.3 VOCABULARY Words used in procedures should convey precise understanding to the trained person. The following rules apply:
Use simple words. Simple words are usually short words of few syllables. Simple words are generally common words.
Use common usage if it makes the procedure easier to understand.
Use words that are concrete rather than vague, specific rather than general, familiar rather than formal, precise rather than blanket.
Verbs with specific meaning should be used. Examples are listed in Table 1.

11 Rev 0 NL01-RRF13-PGP
r BIG ROCK POINT NUCLEAR PLANT SPECIFIC WRITERS GUIDE FOR EMERGENCY OPERATING PROCEDURES 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 safety function (s) in the intended manner. Implicit in this definition is the assumption that all necessary attendant instrumentation, controls, electrical power sources, cooling or seal water, lubrication or other auxiliary equipment that is required for the system, subsystem, train, component or device to perform its safety function (s) are also capable of performing their related support function (s).
b.
Operating - This word means that a system, subsystem, train, component or device is in operation and is performing its specified function (s), and that "Out of Service Tags" or other conditions do not prevent it from maintaining that service.
c.
Available - This word means that a system, subsystem, train, component or device is operable and can be used as desired; however, it need not be operating.
5.4 NUMERICAL 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 should be preceded by a zero; for example, 0.1.
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.
Engineering units should always be specified for numerical values of process variables. They should be the same as those used on the control room displays; for example, psig instead of psi.
5.5 ABBREVIATIONS, LETTER SYMBOLS AND ACRONYMS The use of abbreviations should be minimized because they may be confusing to those who are not thoroughly familiar with them.
Abbreviations may be used where necessary to save time and space, and when their meaning is unquestionably clear to the intended reader. The full meaning of the abbr *viation, other than the abbreviations listed in Table 2, should be written in before the first use of the abbreviation and whenever in doubt. Consistency should be maintained throughout the procedure.
