'-~ (l) PREPUBLICATION DRAFT EMERGENCY PROCEDURE GUIDELINES Revision-3I BWR 1 through 6 December 8, 1982 e

LASALLE COUNTY STATION EMERGENCY PROCEDURE GUIDELINE TECHNICAL GUIDELINE This Technical Guideline has been generated from revision 3I of the toergency Procedure Guideline. Any differences between revision 3I and . revision 3 of the EPG has been designated by a letter in the margin. Attachment A consists of a description of the change and the appropriate reason. Rach change is noted every time it appears throughout the Technical Guideline. All parameters have been changed to comply with LSCS physical characteristics. The following systems are not installed at LaSalle and all references to them are-lined out without consnent. 1. IC 2. HPCI 3. Mk III containment 4. Heated Reference Legs 5. Mk I Containment 6. SPMS ~1. LPCS-B

i Emergency Procedure Guidelines INTF!ODUCTION Cased on the various BWR system designs,-the following generic symptomatic cmergency procedure guidelines have been developed: -RPV Control Guideline Primary Containment Control Guideline secondary Containment Control Guideline iloactivity Release Control Guideline The RPV control Guideline maintains adequate core cooling, shuts down the reactor, and cools down the RPV to cold shutdown conditions. This guideline is entered whenever low RPV water level, high RPV pressure, or high drywell pressure occurs, or whenever a condition which requires reactor scram exists and reactor power is above the APRM downscale trip or cannot be determined. The primary Containment Control Guideline maintains primary containment integrity and protects equipment in the primary containment. This guideline A is entered whenever suppression pool temperature, drywell temperature, Ks containment temperature, drywell pressure, or suppression pool water level, is cbove its high operating limit or suppression pool water level is below its 4 low operating limit. The Secondary Containment Control Guideline protects equipment in the secondary containment, limits radioactivity release to the secondary containment, and either maintains secondary containment integrity or limits radioactivity release from the secondary containment. This guideline is cntered whenever a secondary containment temperature, radiation level, or water level is above its maximum normal operating value or secondary containment differential pressure reaches zero. The Radioactivity Release Control Guideline limits radioactivity release into areas outside the primary and secondary containments. This guideline is entered whenever offsite radioactivity release rate is above that which requirc.s an Alert. l The entry conditions for these e:nergency procedure guidelines are symptomatic L of both emergencies and events which may degrade into emergencies. The guidelines'specify actions appropriate for both. Therefore, entry into procedures developed from these guidelines is not conclusive that an emergency has occurred.

Emergsney Procsdure Guida11nts Table I is a list of the abbreviations used in the guidelines. Brackets [ ] enclose plant unique setpoints, design limits, pump shutoff pressures, etc., and parentheses ( ) within brackets indicate the source for the bracketed variable. Illustrated in these guidelines are variables for a typical BWR/4 or BWR/6 as appropriate. At various points throughout these guidelines, precautions are noted by the symbol: 5 The number within the box refers to a numbered " Caution" contained in the Operators Precautions section. These " Cautions" are brief and succinct red flags for the operator. The basis for each caution as well as for every step i is provided in Appendix B. The emergency. procedure guidelines are generic to GE-BWR 1 through 6 designs in that they address all major systems which may be used to respond to an emergency. Because no specific plant includes all of the systems in these guidelines, the guidelines are applied to individual plants by deleting statements which are not applicable or by substituting equivalent systems where appropriate. For example, plants with no low pressure injection system will delete statements referring to LPCI, and plants with Low Pressure Core Flooding will substitute LPCF for LPCI. At various points within these guidelines, limits are specified beyond which certain actions are required. While conservative, these limits are derived from engineering analyses utilizing best-estimate (as opposed to licensing) models. Consequently, these limits are not as conservative as the limits specified in a plant's Technical Specifications. This is not to imply that operation beyond the Technical Specifications is recommended in an emergency. Rather, such operation may be required under certain degraded conditions in order to safely mitigate the consequences of those degraded conditions. The j - limits specified in the guidelines establish the boundaries within which continued safe operation of the plant can be assured. Therefore, conformance i-with the guidelines does not ensure strict conformance with a plant's Technical Specifications or other licensing bases.

Section 1 INTRODUCTION 1.1 PURPOSE The purpose of this procedure is to provide administrative and technical guidance on the preparation of LGA's. 1.2 SCOPE. This procedure applies to the writing of all of LaSa11e's symptom-based emergency procedures, LGA's. Section 2 80P DESIGNATION AND NUMBERING 2.1 Procedure Designation Designation of the emergency procedures will be WA - LaSalle General Abnormal. 2.2 Procedure Numbering o The emergency procedure numbering system is divided into two components - the procedure designator, LGA. and a serialized two digit number which identifies the WA. Example: LGA-01 o Tables that are part of the LGA's shall be labeled with the appropriate LGA number followed by "T" for table and a serialized one digit number. Example: LGA-T1 or WA-04-T1 Section 3 FORMAT B.1 LGA SECTIONS Rach WA shall be divided into four sections - A. PURPOSE - defines briefly the basic purpose for the procedure. B. ENTRY CONDITIONS - lists the entry conditions for the procedure. C. OPERATOR ACTIONS - the body of the procedure. D. REFERENCES - lists procedural references from the WA's. 3.2 PROCEDURE HEADING M PAGE IDENTIFICATION Bach page of the 14A'a: will be identified by the procedure number, the revision number, the revision date, and the page number. The pages will be numbered sequentially with the word " final" on the last page. Page 1 DOCUMENT ID 00691/

~ 3.3 INSTRUCTION STEP NUMBERING o Instruction stsps will be numbared and idsntified as follows: A. 1. 'a. (1) (a) o-When an instructional step that is a subordinate step appears on a different page than the governing step, the complete number shall be used at the start of the page. For example - step a. of the second step in Section A appears on a different page than step A.1.a. If this step heads the page, it shall be labelled step A.2.a instead of just a. 3.4 PAGE FORMAT' o. Margins shall be at-least 1 1/4" on the binding side and 1/2" on the other side. o. See the example below for proper alignment. Space 4 times after "If" and 2 spaces after "Then". f C. OPERATOR ACTIONS 1. I_f. X (start typing here) Then X 4. (1) (a) 3.5 -TYPE SIZE Use pitch 10 type size so that the procedure is readable under low light conditions. Section 4 WRITING IAA's 4.1 WRITER'S INTRODUCTION ~The IAA procedures exist as an aid to the operator to provide accurate, usable direction to his actions so that he may best cope with degraded conditions that have potential to threaten the plant and the public. The LGA -writer must keep this in mind whenever the 14A's are being drafted or revised. The IRA's are a tool for the operator and as such they must be usable by the operator. Of course technical content is extremely important; but exactitude in the technical content of a procedure is of little value if Page 2 DOCUMENT ID 00691/

'it is not writtsn in a mann2r that can be'undarstood and followed by an operetor during sccidsnt conditions. Tha LGA writer in tasksd with turning a tschnical documsnt (ie - Em3rgsncy Procedure Guidelints) into e functional operator's tool. To accomplish this goal he must approach this translation task from the operator's viewpoint. The writer has to ensure that the intent of the Technical Guideline is maintained, while at the same time the " usability" of the procedure is maximized.

The guidance provided by this procedure will help maintain the clarity and consistency of the LGA's.

The rules set forth here are generally applicable throughout the procedure; however, there may be exceptions. If careful analysis reveals that a particular principle may not-be the best rule to use'for a certain circumstance, then that rule may be violated. Even though a rule may be bent to fit a special situation, it will only be intentionally violated when it promotes the overall effectiveness of the procedure. The major task for the 14A writer is not to produce a product with absolute engineering perfection; it is not to blindly follow the writing guidance contained in this guideline; but his task is to produce a procedure that can and will be used by the operator whenever the levels of plant safety are degraded. 4.2 kRLATIONSHIP O_E LGA's T_O OTHER PROCEDURES During normal large scale plant evolutions the plant's operation is - governed by the 14P's. More detailed, system-specific instructions for operation are provided by the LOP's. Alarm information is provided by the annunciator lan's. Instructions for testing equipment is provided by the - IDS's. Abnormal operating instructions for specific events are provided in the tak's. All of these operating procedures are used in conjunction with the others; sometimes more emphasis is placed on one type of procedure than another; other times a certain type of procedure may not even apply. 'The crux of the matter is that all of these operating procedures have the normal function of guiding the operation of the plant safely within the bounds of the license. Whenever conditions degrade to the point where the safety of the plant is diminished, entry into another type of procedure, the IAA,'is required. The LGA entry conditions do not necessarily indicate that an emergency exists but are degraded parameters which may lead to an emergency. When an LGA'is entered, it will be.the governing procedure. The operator will follow the directions given by the IRA. He will be using the other' station procedures to support the LGA direction. For example, the operator will still be responding to annunciators and the LOA annunciator procedures. He may be following instructions from an LGP or 144, yet he will still be in the IAA. When the 14A's are exited, the operator will return to the normal operating procedures or to special operating instructions written for recovery. 4.3 INSTRUCTIONAL 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 to meet these objectives are as follows: o Instructional steps should deal with only one idea. 4 Page 3 DOCUlWNT ID 00691/

o-Short, sicple santsnces should be umsd. .o compicx'ovolutions should be broken down into a series of simpler steps o -The action the operator takes should be clear. o Expected results of routine tasks should not be stated. o Operator actions should be related to observable plant parameters. When possible, avoid.using time as a key to operator actions. o Give the operator enough information to accomplish the task but j don't give him too much information to read. Don't clutter the procedure up with too much verbiage. There will be times when { identical series of steps will be repeated. Inclusion of these same steps at every point in the procedure would make the procedure . harder to follow. In these cases, the procedure will work better if the repeated steps appear at the back of the procedure book clearly identified with a tab. Whenever a conditional statement calls for taking the action, the operator will go to the tabbed section. When he has taken the required action, he will return to the procedure from which he came, o When a list of items requires actions to be taken in a specified ~ order, use the words "in the following order" or similar terms to identify the necessity of sequencing. Otherwise a listing would infer no specified order is required and leave the sequence up to the operator's judgement. 4.4 IF/THEN LOGIC o Whenever a condition appears in the procedure that will require prescribed operator action, the If/Then logic style should be used if it will make the procedure more clear. o The words "If" or "When" will normally precede the conditional statement. The word "Then" will precede the action statement. If, Then, and When shall be underlined when they are used to begin o conditional logic statements. o .The LGA's shall be written so that the If/Then logic is used l consistently. The procedure shall be constructed so that the l-operator will take the correct actions if he enters the procedure at the proper point and follows the logic given the following guidelines -- i l' "lF"- The operator reads the condition which follows. If the condition applies, he takes the action which follows in the related "Then" statement and goes on to the next procedural i step. If the condition does not apply, he does not have to l' even look at the "Then" statement, but continues on to the j next procedural step. l Page 4 i DOCUIENT ID 00691/ i

f "Then" - Th2 Ection statement which follows the "Then" will be taktn by the oparctor if the condition (tha "If" statement or the "When" statement) applies to the plant condition. If the conditional statement does not apply, the operator does not even have to read the action statement, but goes on to the next procedural l step. Even if the condition does apply and the . operator is performing or trying to perform the prescribed action, he should look ahead to see if the ensuing conditions apply. "When" - _The "When" statement is a special kind of "If" statement. "When" does the same thing as "If" except it. infers that the step may apply at a later time. "When" emphasizes that the operator should be looking for the associated condition and that the condition is likely to occur at a later time. When the associated condition does occur, the operator should take the action specified by the "Then" statement. The "If" statement technically does the same thing, "When" is used for emphasis, care should be taken not to overuse "When" to preserve its emphatic value, o The."If/Then" logic takes the operator from the entry conditions through the procedure until he exits the procedure or the "If" statements no longer apply. Generally, the further the operator 9ets into the procedure, the more degraded,the conditions are; hence the actions become more drastic. As the operator gets deeper into the procedure, he should not ignore the previous steps; he should still be taking actions those steps required. The operator should periodically go back through the previous "If" statements and ensure that if they apply, that he is taking the required actions. Conversely, the operator should not get stuck on an early step. He should look ahead in the procedure for conditions that might require more drastic actions. o Whenever practical, the "Then" statement should appear on the same page as the "If" statement. 4.5 CAUTIONS AND NOTES o Step specific cautions should precede the steps to which they apply. o Procedure specific cautions should precede the procedures to which they apply, o General Precautions should be included be included in a table at the front of the procedure. The General Precautions snould be stressed during training. o Notes should precede the steps to which they apply. Page 5 DOCUMENT ID 00691/

o CAUTIONS cnd NOTES ghall be emphtsizcd. Tha harding thall be all c:p2 cnd cantered ov2r th2 stctement. Tha hatding chall be

underlined. The cautionary statement or note shall be conventionally typed using both upper and lower case letters to make it easier to read. The entire note or caution shall be enclosed by a box. See the example below:

i l l CAUTION Cooldown rates above 100'F/hr may be required to accomplish this step. o CAUTIONS and NOTES should not contain action steps. They should be informational or warning devises only. In rare cases a CAUTION or NOTE may have to contain an action or inferred action. This shall only be done after a very careful assessment of alternatives. o CAUTIONS and NOTES shall not be overused. If too many CAUTIONS or NOTES,are used the importance of the message may be diluted. Cautions may be minimized through training or by writing the information into the procedural step itself. o CAUTIONS and NOTES should appear in their entirity on a single page. Do not split CAUTIONS and NOTES between pages. o The step to which a step specific caution applies should appear on the same page as the caution. 4.6 GRAPHS. TABLES and ATTACHNENTS o Graphs, Tables, and Attachments should be easy to read and easy to use by the operators, o ' Units should be the same as those in the Control Room. o Graphs. Tables, and Attachments shall be labeled clearly. Graphs shall have a noun name and sequential. number. For example, IAA-03-G2, RPV Saturation Limit is the title of the second graph in 14A-03 and it defines the RPV Saturation Limit. o The use of graphs shall be minimized. When a single value can be used, it is better than using a graph. o Graphs will normally appear on the face adjacent page to where it is referenced in the text of the procedure. An exception may occur if an overriding Instruction applies to the same page that references a graph. When an overriding Instruction appears on the face adjacent page, the graph will be included on a foldout page. o. Where possible use a full page for the graphs. o The maximum number of divisions per inch for the axes of graphs should be 10. Page 6 DOCUMENT.ID 00691/

o .All numbers on tha grcphs should be at least 4 mm high. o All exas of tha graphs chall be clearly 1Ebeled and include the j units of measure. 4.7 USE OF UNDERLINING -o Underlining will be used for special emphasis. o The headings for " NOTE" and " CAUTION" shall be underlined. o Underlining shall be used to emphasize negatives. o Underlining s. hell be used to emphasize the logic terms, "If", "Then", and *When", o Underlining may be used.to emphasize connectors such as and or of when it will increase effectiveness. o Underlining may be used to emphasize other words in the procedure; however, the use of underlining should be limited so that the emphatic value is maintained. 4.8 REFERENCING AND BRANCHIW,TO OTHER PROCEDURES OR STEPS When the term " referencing" is used in connection with another procedure. it implies'that the referenced procedure will be used as a supplement to the procedure presently being used. o Referencing other sections, pages, or steps within other procedures can result in error. o Excessive forward and backward referencing within the same procedure can be confusing and can lead to skipping of steps, particularly since the referenced steps may not return the operator to the directing step. Also, important information preceding a referenced step can be missed. o If operators are required to use many procedures at the same time, there is a possibility that the referenced information may not be obtained and used or the exit point from the original procedure 4 might be forgotten. Important steps might be missed and operator delay might result. When the term " branching" is used in connection with another procedure, it signifies that the procedure being used is to be exited and the new procedure is to be used in its entirety. Branching is an acceptable method of entering another procedure and eliminates most of the problems associated with referencing. In determining whether to reference another part of the procedure for -instructions or to repeat the instructions within the procedure, consider the following factors: o If the referenced instructions can be repeated without greatly increasing the length of the procedure, repeat them. Page 7 DOCUMENT ID 00691/ .. ~.

o . Tabbing referenesd sactions too long to repeat would assist the operator in loccting tha information quickly. o If the procedure splits into two or more optional paths, references to other steps may be unaviodable. o-When multiple paths are taken from a single step, a matrix can be made that refers the operator to a procedure step tabbed with the same color as.the matrix box. Two types of procedure referencing are used in the 14A's, o one type of procedure referencing requires the operator to get out the referenced procedure, observe the precautions and limitations in the procedure, and to follow it step by step..When it is required that the operator follow the procedure this closely, he will be directed to take the action "h accordance with" the referenced procedure. An example of this kind of reference would be -- If Drywell pressure exceeds 45 psig AND Containment Radiation levels indicate 10CFR100 limits will not be exceeded Then VENT the Drywell through valve 1(2)VQO35, Drywell Vent / Purge Outlet Downstream Isolation to SBGTS in accordance with LOA-VP-03, Emergency Primary Containment Pressure Relief. In this case, if the conditional statements were satisfied, the operator would go to IDA-VP-03, follow the procedure through (even though he is still in the IDA) until he has vented the drywell M accordance with LOA-VP-03, then he would return to the 14A from which he came and find the correct steps to take next. o The other type of procedure referencing is just that - a reference. It is an aid to the operator giving him a reference for more detailed information on the task. This type of referencing is done by placing the referenced procedure in parentheses. For example -- When the RHR Shutdown Cooling interlocks clear her), INITIATE the Shutdown Cooling mode of RHR (LDP-RH-0~1) 4.9 COMPONENT IDENTIFICATION o Components identified in the 14A's shall be identified by common usage terms. The components shall be identified in the " language .of the operator." When confusion may be a problem, use the nameplate _ terminology on the control room labels. f Page 8 DOCUMNT ID 00691/

' Acronyms may be ussd in the WA*a but only whtn thsy are o univarsally undarstood by tha operators. A list of ccronyms used in the WA's'chall be,includsd in Table 1 of ths WA Writer's Guide. The Training Department shall be provided a copy of the Table 1 whenever the list is revised. 4.10 UNITS OF MEASURE l o Quantitative values should be stated within the range and accuracy of the instruments. An_ exception to this rule can be made when the common usage term does not fall within the accuracy of the instrumentation. An example of an exception would be the Tech Spec value for high drywel pressure, 1.69 psig. 1.69 psig is the setpoint the operators are trained on and is the casunon usage term for the high drywell pressure scram and isolation setpoint. 4.11 CONCURRENT ACTIONS / OVERRIDING INSTRUCTIONS o There may be events which will require the operators to be in more th'an one WA at the same time. Care must be taken to write the procedures such that the concurrent operator actions will not conflict. o There may (or may not) be instances where the operator continues past a conditional statement to subsequent procedural steps only to have the previous condition satisfied. When it is very important that the operator return insnediately to the previous step (ie - continuing with the later step may worsen the condition) and relying on the operator's memory or training is not feasible, then an " Overriding Instruction" is required. Overriding instructions shall appear on the face adjacent page to where it might apply. The overriding Instruction acts as a reminder to the operator that he needs to maintain awareness of the conditional statement in the instruction. 4.12 CONNECTORS (AND, OR) LISTS i o When a step contains more than three objects of an action, list them rather than imbedding them in a sentence. o When three or more conditions are associated with an action, list them separately ahead of the action statement. o When it is very important to connect two statements it may be best to separate the two statements vertically with AND emphasized by l capitals and underlining. For Example -- If the Suppression Pool water level can not be maintained below 26' 10" (+3") i AND adequate core cooling is assured l Then! TERMINATE injection into the reactor Page 9 DOCUMENT ID 00691/

'o -Whtn "cnds" cnd "orn" are sixtd care aust be taksn to snsure that th2 prepar combin:tions are undaretood. Usa of " ands" and " ors" is easiest to demonstrate by example. Assume there are three items A,B, and C. If we either wanted "A" or else both "B" and "C" it should be written: "A" O_R. .B" AND "C" If we wanted "A" and also wanted either "B" or "C" it should be written: "A" AND "B" OR "C" 4.13 CHECKOFF BLANKS o checkoff blanks shall be provided in the left hand margin adjacent to conditional statements were a check might help keep track of where the operator has been in the procedure. These checkoff blanks are not mandatory for the operator to complete, but are there for convenience if he thinks they will keep him on track. 4'14 CAPITALIZATION o conventional rules for capitalization shall be used except when special emphasis is warranted. o control Room indicator nameplate references shall be capitalized. o Action verbs shall be capitalized. o Acronyms shall be capitalized. o Words with a special meaning may be capitalized. An example would be NORMAL INJECTION SYSTEM. o Headings for procedure sections shall be capitalized. o Headings for CAUTIONS and NOTES shall be capitalized but the body shall use conventional upper and lower case letters. o connectors that-are used to vertically separate items shall be capitalized. _4.15 UNIT LESIGNATION Because of-the identical nature of the two units at LaSalle, the-procedures shall be written to provide guidance for both units. When equipment is identified by EPN, the unit one number shall be o listed first followed by the unit two number in parentheses. For 1 example -- "C1 HSE the RWCU isolation valves 1G33-F001(2G33-F001) and 1G33-F004(2G33-F004)." i Page 10 DOCUIENT ID 00691/ - _ _. - - - -.... - -.. ~ - -,. -,.. -.. - - -. -

? Trcining Description for LaSalle Genarol Abnormal (LGA) Symptom-bassd EmargEncy Procsdures - PORWARD - The following text describes the training process LaSalle Station plans to use for implementing a revision to the LGA's. It is important to realize that symptom-based emergency procedures are not new to the LaSalle licensed operator: LaSalle was the first plant to implement emergency procedures based upon the symptom-oriented Emergency Procedure Guidelines published by the BWR Owners Group. During 1981 LaSalle licensed personnel and license candidates were given one week of concentrated training on the new, symptom-oriented emergency procedures (LGA's). LaSalle Unit I has been safely operated using the upgraded LGA's since the operating license was received in April of 1982. Unit 2 has been safely operated throughout the startup test program using the LGA's. LGA training was included in the License Requalification Program in both 1983 and 1984. The LaSalle licensed operator has already been trained on, and is using the symptom-oriented procedures mandated by NURBG 0737. The guidelines on which the LGA's were based have been revised to incorporate reactivity control, secondary containment control, and radioactive release control. Consequently, the LGA procedures are being revised to reflect these changes. Since the reactivity control changes increase the complexity of the procedures, a significant training j effort is planned. The following text describes the training program which LaSalle plans to use to train licensed operators on the revised procedure. It should be noted that this training description is as we 1 plan it in September 1984. There may be content or structure changes to the program if these changes will further our goal towards safe and practical operations of the LaSalle County Units 1 and 2. INTRODUCTION The revised LGA training will consist of a Classroom Training session and ,~ a Practical Training session. The two sessions together should provide the trainee with the information necessary to obtain the objectives. The - training will be provided for RO and SRO licenseholders at LaSalle. The operating crew members shall receive the training before performing licensed shift duties under the revised procedures. LGA LEARNER OBJECTIVES State from memory the entry conditions for Level control, containment control, and Reactivity Control. Locate Control Room instrumentation that monitor parameters which are LGA entry conditions. j Determine when the LGA's may be exited to normal operating procedures. Discuss the basic flowpath for Alternate Shutdown Cooling. Given tne graph, discuss the basic reasons for taking actions when any of the parameters reach limits defined by graphs in the LGA's. DOCUMENT ID 00671/ l L'

Givin-th2 cppropriate graph and appropristo plcnt paramaters, datornint whether limita d2finsd by graphs in tha LGA's cre being approrchsd or exceeded. f Define any acronyms used in the LGA's. Discuss any instrumentation / procedure differences between U-1 and U-2 that impact upon the 14A's. Discuss the alternate methods for shutting down the reactor. Using the LGA's, simulate the operator's actions required to shutdown the ) reactor given a failure to scram. j Using the LGA's, simulate the operator's actions required to maintain adequate core cooilng given a postulated transient with coincident equipment failure. Discuss each General Precaution outlined in LGA-T1. Discuss selected Cautions using the LGA procedures. Using the LGA's, simulate the operator's actions required to maintain primary or secondary contanment parameters within limits. CLASSROOM TRAINING SESSION, Each licensed operator shall receive classroom training on the LGA's. This classroom training will be considered complete when the licensed operator scores 80% or above, on the written LGA examination. Additional training will be required if the trainee scores below 80% on the written examination. The test questions should reflect the intent of the LGA learner objectives. The classroom training session should take approximately three days. A typical day would be comprised of four hours of lecture, two hours of discussion and two hours of self study. Two hours will be allotted on the final day of training for the LGA examination. The student materials for the course shall include: l LGA Student Handout LGA procedure available for reference LGA Flowchart available for a graphic representation of procedural flowpath. l The LGA student handout will contain two major sections - an introductory section and a procedural step explanation section. l INTRODUCTION - Will include an overview of the revised procedural structure and a review of how to follow the LGA's. This introduction will encompass the following topics: - General Procedure Layout - Logic Terms l - Use of General Precautions DOCUMENT ID 00671/

.- U o of Stcp Spscific Crutions e - U;2 of Proceduro SpIcific Clutions - Action Verbs l - Special Definitions - Entry and Exit of the LGA's - Use of Accompanying Support Procedures PROCEDURAL STEP EXPLANATION - will cover each procedure and explain why operator actions are taken. This will be accomplished by dissecting the procedures into major subsections and explaining each evolution. PRACTICAL TRAINING Each licensed operator shall receive practical training on using the LGA's. The practical training will include a simulation of postulated transients which will require entry into each LGA. This training will normally be conducted on the LaSalle simulator. Two 4-hour shifts will be scheduled for LGA simulator training for each license holder. Under special circumstances, an actual control room walkthrough may be substituted for the simulator training to fulfill the practical training requirement. This special substitution must be approved by the Training Supervisor before it will be allowed. FEEDBACK LOOP Each trainee shall be provided with a feedback form as a means of collecting input from the license holders not only on the course but on the procedures themselves. This feedback will be considered for changes to the lesson plans and appropriate comments will be forwarded to the Operating Department procedure writers. DOCUMENT ID 00671/ -}}
