Abnormal, and Critical Safety Function procedures. This includes the following procedures.
- a. Emergency Response Procedures 1). Emergency Operating Procedures (BEP) 2). Event Specific Subprocedure (BEP ES) 3). Emergency Contingency Actions (BCA)
- b. Abn,ermal Procedures (BOA)
- c. Critical Safety Functions 1). Status Tree's (BST) r 2). Functional Restorations (BFR) 4.0 DEFINITION 4.1 Ene oency operatina Procedures (BEP)
BEP's are a four procedure set that initiate operator action based upon either a reactor trip or safety injection. They diagnose and mitigate the immediate consequences of a LOCA. SGTR. (Steam Generator Tube Rupture) and LOSC (Loss of Secondary Coolant).

- e BAP 1310-A3 Revision 0 4.2 Event specific subprocedures (BEP ES)
If certain conditons are met or ciceeded in the BEP's, the BEP ES will direct actions to accomplish the given objective or supply new actions based on observed conditions.
4.3 Emeraency Continaency Actions (BCA)
BCA's are procedures provided due to a direct NRC requirement without regard to their combined failure probability. These include, A WS, loss of all AC. SGTR contingencies, and others.
- 4.4 Abnormal Operatino Procedures (BOA)
BOA's provide guidance to the operator when important parameters or ,
4.5 Critical Safety Function Status Trees (BST)
- The BST's are a set of six decision trees that evaluate the six l critical' safety functions to determine if the function is intact or being challenged. If challenged it will reference the restoration j guideline for restoring the function.
, 4.6 Functional Restoretion Procedures (BFR) l The BFR's direct operators action to recover / restore the degraded safety function dependent on which CSF is challenged and the extent of degradation.
l l 4.7 Inusediate operator Action Actions taken to stop the degradation of the condition and mitigate I the consequence of the event. These actions must be taken ismediately to prevent further degradatica.
4.8 Subsequent operator Action Actions that the operator uses to take the plant to a normal stable or safe steady state condition. These actions form the major body of the procedures, and should follow the inusediate actions without interruption.
5.0 PROCEDURE DEVELOPMENT 5.1 BEp, BEP-ES BCA's. BST. BFR's i The above referenced procedures are to be generated in plant specific !

BAP 1310-A3 Rovision 0 The generic WOG's will be modified to reflect specific Byron Plant considerations. Care will be taken not to deviate from the major flowpath. Changes made to the procedures will be documented for the convenience of On-Site Review, and be included in the basis document. In Addition any setpoint that requires off-site calculation will also be documented. Plant specific procedures will be verified and validated per the Byron Verification and Validation Guide. -
5.2 BOA These procedures will be rewritten to utilize the two column format.
and will include some additional procedures to reflect the new BEP reorganization. These procedures will use the previous BOA's and Zion AOP's for guidance in their generation. Since the BEP's are not entered until a reactor trip occurs, these procedures will be designed to give guidance to the operator until a trip occurs, or until an orderly shutdown can be accomplished.
6.0 REQUIREMENTS 6.1 General considerations
- a. The fol' lowing considerations will be utilized in development of the Emergency / Abnormal /CSF procedures.
1). High readability '
2). Easily comprehendable 3). Easily learnable
- b. Procedures developed for control room use will not include information useful for only training purposes. Explanatory information will be available for formal and independent training to provide a comprehensive background, and deeper understanding of the procedures. However, this information will not be included in the procedures. This will aid the operator
. to quickly discern the major flowpath of the procedure.
- c. If several tasks must be performed concurrently, the concurrent tasks shall be consistent with normal plant manning.
6.2 style
- a. Word Usage 1). The simpler spelling will be used whenever a choice is indicated in the dictionary. Short words and commonly used words are recommended.
2). Nomenclature and acronyms used in operator training will be incorporated into the procedures.

BAP 1310-A3 Revision 0 3). Use simple word order as auch as possible: 1.e.: subject, verb and object, 4). There will be only one main thought per sentence.
5). Use positive statements to address required actions I (e.g., CLOSE the " Valve").
6). When addressing a concept, object or operation, be consistent in referring to it throughout the procedure (e.g., do not use unit, assembly, equipment and component interchangably).
7). When referring to equipment, control switches, instrumentation, etc., the nomenclature including acronyms and abbreviations as used on specific components in the plant shall be used.
8). Numbers will be arabic numerals, and will not be spelled ,
out except when the number begins a sentence.
9). For familiar acronyms the use of the acronym is preferred rather than the complete title spelled out.
10). The following words will be used in accordance with their definition below, a). Verify -
confirm that an expected condition exits.
b). Check -
note the condition of c). Manually -
operator action required at the main control board.
d). Locally -
operator action required in the plant, usually at the specific equipment location.
e). Maintain - sustain or continue with at a relatively constant value, parameters or conditions l
as specified in the step.
f). Monitor - watch or observe a parameter at certain time intervals, that are either designated l
l or determined by the operator.
11). When a high level step starts with verify, check, or maintain, the low level step should usually start with a noun in a broken sentence. The broken sentence will have the parameter and the expected response.

When a high level step starts with, establish, align.
reset, block, unblock, determine, investigate, calculate, isolate, manually, locally, continue, initiate, adjust or evaluate, the low level step should usually start with a verb.
For example:
Establish Component Cooling to _ _ _ _ _ _ .
a). Open valve _ _ _ _
b). Start pump _ _ _ _.
12). Abbreviations, when used, will follow the approved station abbreviation list (BAP 131072).
13). The logic terms AND, OR. NOT. IF. IF NOT WHEN and THEN are used to precisely describe a set of conditions or sequence
- of actions. When logic terms are used they will be underlined and capitalized for emphasis.
The use of AIO and O_R_ within the same action shall be avoided. The word AND shall not be used to join together more than three conditions. If more than three conditions need to be joined a list will be utilized.
When action steps are contingent upon certain conditions or combinations of conditions, the step shall begin with the words IFF or WH8EN 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 conditon. IfF,is used for an unexpected but possible condition.
- b. , Level of Detail The level of detail required for the BOP's must not be so excessive, that readability and timely execution cannot be maintained. The level of detail desired is that which a newly trained and licensed operator would find adequate in emergency situations. For example, extremely familiary valves would be referenced, with only their valve number, e.g. " Place PCV 131 in manual." Valves with less operator familiarity would be referenced with both the valve number and name, e.g., "open accumulator vent header isolation valve HCV 943."

- c. Measurement - Units and Tolerance 1). Units or measurement for most engineering parameters will be expressed in units of the English Engineering System.
3 These units will be conistent with the Instrument display on the main control board.
2). The high and low tolerance for various parameters may be presented where required for practical, a single parameter with the tolerance listed as a plus or minus must be avoided.
Example avoid: 2235 1 15 psig use: 2220 - 2250 psig Tolerances given on parameters.should be consistent with the associated instruments display. Therefore, do not use a tolerance of i 30F if the display is given in 200F increments.
3). For numbers less than unity, the decimal point should be preceeded by a zero. For example 0.1.
- d. Emphasis 1). 6.mphasis of necessary key words and phrases will be made i readily visually recognizable by the use of an underline.
For example, all logic words will be underlined. (IF, NOT, THEN). Additional emphasis may require the use of select capitalization.
- e. Cautions and Notes 1). Cautions will be used to attract attention to essential and critical information and will usually address the following as applicable:
l I
a). Specific nature of hazard b). Specific location of source of hazard c). Time considerations if applicable d). Consequences of not heeding caution, if not obvious.
2). Notes will be used to delivec critical information only.
l 3). Cautions and notes will proceed the step to which they apply.
4). If a caution or note is general enough to apply to the majority of the procedure, then it should be placed in front of the first action statement.

6). cautions will normally not contain action steps, or be used to deliver connand data. Use of an action step in a caution will be used infrequently, and only as warranted by unusual circumstances.
. f. Attachments 1). Attachments may be used as necessary to aid the operator in accomplishment of the goal of the procedure. These may include checklists, flowchartz, decision trees, tables, or foldouts, and appendices. Attachments are used when inclusion of the information in the procedure would cause unnecessary " clutter", and reader confusion.
2). Attachments will be numbered sequentially based on their order of appearance in the procedure,
- g. Foldouts 1). Foldout pages contain information that should be monitored throughout the procedure. The foldout is contained in the back of the p:ceedure and is " folded out" upon entry into the procedure.
- h. Branching to other Procedures 1). Most procedures may have " kick-outs", which direct the operator to go to another procedure as conditions require, or as a rediagnols directs. These procedure transitions are necessary to ensure proper operator response. To minimize confusion the words "Go to" will be used to direct the operator to leave one procedure and go to another.
, Therefore the ooerator will know to leave one step and not return until directed. The same mechanism will be used to direct movement to different steps in the same procedure.
6.3 Format for BEP, BEP-ES, BCA, BOA, BFR

"A closed bullet" requires a_1_1 steps to be completed in any order g (5). An "open bulles' proceeding multiple steps requires only the steps that apply to be completed in any order (o).
7). The procedure steps shall be arranged so that the user continues down the left-hand column for normal recovery.
8). Each high-level step should have a corresponding contingency action entry in the right-hand column. if practical.

10). If a contingency action cannot be completed. the user should return to the next step in the left-hand cclumn.
unless instructions in the right-hand column specify otherwise.
11). To differentiate imediate actions steps from subsequent actions, the immediate action step numbers shall be boxed.
(Immediate action steps are those which cannot be delayed).
12). Immediate actions should be limited to those required to accomplish the following:
a). Verify automatic actions.
b). Assure the reactor shutdown margin is adequate.
c). Establish core cooling.
d). Verify electrical power available.
i e). Confirm no uncontrolled release in progress.
13). Supplemental / subsequent actions should be steps required to accomplish the following:
a). Diagnose and take the reactor to normal or steady state conditions.
b). Verify immediate actions.
c). Provide transition to appropriate procedure by specific symptom identification.
14). Automatic actions will be verified in the procedure body.
This verification will be based on a technical priority.
Only those automatic actions which have a direct effect on the procedure, or adverse consequence on the plant, will be verified.
l , 15). Steps will be sequenced primarily according to technical necessity. Additional consideration will be given to l control room organization, and layout. to prevent cumbersome operator movement. However, technical necessity l
will be the first consideration.
a). Non-Sequential Steps Non-sequential steps are those which may be required to be performed at any point in the procedure (eg.
" Isolate accumulator isolation valves below 1000 psi"). These non-sequential steps will usually use the logic terms WiEN. THEN. In some cases a reminder l
will be placed on the foldout sheet. In rare instances, a note or series of notes may be used.

- c. Breaking of Steps:
Steps will not be split between pages unless the length of the step is such that it requires more than a full page in itself. In this case, a continuation statement at the bottom of the page will be required to alert operator of step continuation. If a step appears to go beyond the page length then that step must start the next page. All notes or cautions associated with a step will precede that step and will be on the same page as that step.
- d. Breaking of Words:
Breaking of words shall be avoided to facilitate operator reading.
- e. Operator Aids:
Aids include status trees, graphs, flow charts, tables and appendices.
5 Status trees, graphs and flow charts 1). Number, title and rev$sion will use the same title block as the emergency procedure.
2). Typing of number, title and revision will be in narrator, 10-pitch type style - upper case.
3). The field must not violate specific page margins.
4). Field should be of sufficient size to offer good readability.
5). Grid lines of graphs must be at least 1/16 - inch apart:
, numbered grid lines should be bolder than unnumbered grid lines.
5 Tables will be typed using the following rules:
1). Type style and size must be the same as that for the rest of the procedure.
2). The table number and title must be located above the table field and three line spaces below preceding text.
3). A heading must be entered for each column and centered with the column: the first letter of words in the column headings should be capitalized.
