Docket No. 50-255 Consumers Power Company ATTN:

David P. Hoffman, Vice President Nuclear Operations 1945 West Parnall Road Jackson, MI 49201 Gentlemen:

SUBJECT: EMERGENCY OPERATING PROCEDURES TEAM INSPECTION This refers to the special safety; inspection conducted by an* NRC EOP Inspection Team l~d by Mr. James E. Gagliardo on July 24 through Aug~st 4, 1989, of activities authorized by NRC Operating License No. DRP-20 for Palisades Nuclear Power Plant, and to the discussion of our findin~s with the members of your staff at the conclusion of the inspectio The purposes of the inspection were to verify that your eme"rgency operating procedures were technically accurate; that their specified actions could be meaningfully* accomplished using existing equipment, controls and instrumentation; and that ~vailab1e procedures had the usability necessary to provide the operator with an effective operating tool~ The areas examined during the*

inspection are identified within this report.. Within these areas, the in~pecti6n consisted of a selective examination of procedures and representative records, plant walkthroughs, interviews with personnel, and observation of acti~ities in progres.

.

The resalts of this in~pection indicated that the licensee's EOPs co~ld be:

effectively carried out in the plant and could be correctly performed by the Palisades staff. However, a number of significant deficiencies were identified as follow Although none were determined to pose a significant safety concern, they may pose potential probl~ms for operators.acting under stres.

The EOP verification and validation (V&V) program was not sufficiently comprehensive and needs to be better defined. For example~* the verification and validation effort did not utilize a multidisciplinary team that was independent of the staff involved in writing the EOPs, failed to walkdown EOP actions that were to be performed outside of the control room, and failed to walkdown the other procedures referred to by the EOP.

Quality Assurance involvement and oversight of the EOP development, V&V, training, and feedback efforts was weak in that QA oversight was. limited to a single review of one procedure and an ongoing two-year surveillance of the EOPs which did not include the aspects of training effectiveness 8910270164 891018 PDR ADOCK 05000255 G

OCT l 8 1989 or verification and validation effort No technical audits had been conducte As a result, several of the findings identified by this inspection had not been identified by your QA activitie.

There was insufficient training of auxiliary operators on certain actions they were required to implement under the EOP It was apparent to the inspectors that essentially none* of the in-plant actions required to be implemented *by the Auxiliary Operators had been previously walked down by the.

A number of human factors and technical concerns were identified involving cautions and notes, operator aids, insufficient material presented, and use of a procedure to overcome a plant operating deficienc On a number*

of occasions, operators could not perform actions in the EOPs without first racking in a circuit breaker, unlocking a valve, or operating a key *

switch; however, none of these prerequi~ite actions were identified as steps or cautions in the EOP There were also examples in which room keys, a step ladder, or fuse pullers were required to perform local equipment operations without the EOPs noting suc The step in EOP to secure main feed pumps was being utilized to overcome an equipment problem where the automatic ramp down function did not perform as designed, rather than correcting the equipment proble Some of the above concerns appear to be in violation of NRC requirements, as*

specified in the enclosed Notic A written response is require In addition, your response should. also_address the following:

(1) the results of your determination as to why the main feedwater automatic runback on reactor or tutbine trip does not pefform as des~gned and a 10 CFR 50.59 evaluation determining whether or not this condition represents an unreviewed safety question; (2) a description of the actions you have taken to provide for a comprehensive verification and validation process that would identify and correct the types of deficiercies documented in this report; and (3) a description of your planned ictions for resolving each of the specific items identified in Appendices II (technical deficiencies) and III (human factors deficiencies) of this report including the dates by which those actions will be complete The response directed by this letter and the accompa~ying Notice is not subject *

to the clearance procedur~s of the Office of Management and Budget as required by the Paperwork Reduction Act of 1980, PL 96-51 In accordance with 10 CFR 2.790 of the Commission's regulations, a copy of this letter, the enclosures, and your response to this letter will be placed in the NRC Public Document Roo *

Scope:

This special, announced inspection was conducted in the area of emergency operating procedures (EOPs),- including the implementation of vendor generic technical.guidelines (GTG), overall technical adequacy of the procedures, validation and verification (V&V) _progr~m, the performance 8910270166 891018 PDR ADOCK 05000255 Q

of training on the EOPs, and the ongoing ev~luation of the EOP Results:

No unsafe operational conditions were identified. The overall determination was that the EOPs could be effectively carried out in the plant and could be correctly performed by the staff. Training was adequate overall, but several areas needed improvemen Two viol~tions were identified (inadequate training of auxiliary operators, paragraph 5~c; and insufficient ov~rsight of EOP activities by QA, paragraph 6). The EOPs were generally capable of performing their intended function, but several discrepancies were noted and are documented as EOP technical review items and human factors element review item A major concern was identified regarding the licensee's V&V process, which was not independent of the EOP writers, was not multidisciplinary in nature, and had not reviewed proGedures referred to by

.the EOPs or attachments with actions performed outside the control roo These discrepancies will require further review by the licensee and will be the subject of followup inspection effort One unresolved item (paragraph 3) was also identified regarding the tripping of the main feed water pumps following a reactor tri I r,,

Executive Summary Following the TMI-2 accident, the nuclear power industry embarked upon an upgraded £OP program to provide operators with direction to mitigate the consequences of a broad range of accidents and equipment failure Supplement 1 to NUREG-0737 and NUREG-0899 were issued to establish,

- respectively, the requirement for the upgrade program and the process for development and implementatio Palisades responded to these requirements with an EOP development program consisting of the following significant elements:

The inspection was designed to verify that the

I {;

'

,

vendor step sequence was followed, the exit/entry points were correct, transfer between procedures was well defined*and appropriate for procedures performed concurrently, the procedures could be implemented with the minimum staff required onshift, and notes and cautions were used correctl Deviations from the CEN-152 guidelines were reviewed to ensure that they had been justified and that safety significant deviations were evaluated in accordance with 10 CFR 50.59 and reported to the NRC_as require The inspection team also verified that deviations warranted by the specific plant design were incorporated into the EOPs, prioritization of accident mitigation strategies were correct, and adverse containment values were also considered in the parameter measured/observed in the procedure The licensee had based their EOPs on Revision 3 (Submittal 2) to CEN-152 as approved by NRC letter to the CEOG dated November 5, 1986. *Revision 3 (fin~l) to CEN-152 had been subsequently issu~d and was reviewed and approved by NRC letter to th~ CEOG dated August 2, 198 It was noted that the licensee had prepared Revision 1 to their EOPs to the guidance of Revision 3, Submittal 2, but as the revisions were about to be finalized, Revision 3 (final) was issued and some additional changes were made in the EOPs based on the final revision.. The licensee indicated that Revision 3 (final) would be fully incorporated during the next biennial revie~ of all of the EOP The NRC team conducted inplant and control room walkdowns of the EOP Where the EOPs transferred to supporting procedure~, the inspectors verified that the transfers were correct and walked down the applica~le sections of the.supporting proced~res. With a few exceptions, nomenclat~re was found to be consistent between the control boards and the procedures. _

Those exceptions, which were evaluated as potential problems for operators acting under stress, are identified in Attachments II and II The inspection team's overall determination-was that the licensee's' EOPs could be effectively carried out in the plint and could be corre~tly performed by the Palisades staf Although a number of human factors concerns we~e identified, none were determined to pose a significant safety concer Training on the EOPs was adequate overall, but several areas needing improvement were note The most significant concerns identified during the inspection invoJved the inspector's-observations that (1) the EOP V&V program was not sufficiently comprehensive and needed to be better documented, (2) QA involvement and oversight of the EOP development, V&V, training, and feedback efforts were weak, _and (3) the training of the auxiliary operators (AOs) on actions they were required to implement from the EOPs was very poor..

5 Palisades EOP/CEOG CEN-152 Procedure Comparison (25592)

3.1 Scope of. Comparison A comparison of the Palisades EOPs and the CEOG Emergency Procedure Guidelines (EPGs) CEN-152, Revision 3, was conducted for each of the EOPs

  • . identified in Attachment. The objective of this review was to ensure that the -ljcensee had developed sufficient procedures in the appropriate area to cover the broad spectrum of accidents and equipment failures that must be considere The inspectrirs 1 review of the licensee's EOPs disclosed that the procedures had been developed in accordance with the CEOG recommendation The inspectors reviewed the licensee's documentation and interviewed licensee personnel to verify that any identified deviations from CEN-152 were justifie Discrepancies, identified by the team, between the EOPs and CEN-152, are discussed in Attachments II and II.2 Findings The team determined that, in general, the EOPs incorporated th~ procedure guidelines of CEN-152, Revision 3, and were technically adequat This determination was based on the following findings obser~~d during the review of the Palisades procedures:

0 The EOPs generally followed the CEN-152, Revision 3, step sequence,

-with detai~ed instructions fo~-operator actjons required to cooldown the plant or place the plant in a stable conditio Entry or exit points in the EOPs were clearly stated and could be followed by trained reactor operator *

The plant specific values were consistent with the plant desig The CEN-152 prioritization of the accident safety function hierarchy was maintained in the EOPs..

The licensee's standard p*ost-trip action diagnostic flowchart for reactivity control was expanded from that of CEN-152 to more adequately address the attributes of reactivity control that must be addressed in*

  • the analysi The inspection team determined that a potential equipment problem pertaining to the main feedwater pumps existe The basis for EOP discussed securing the main feedwater pumps because past experience had shown that prolonged operation after a trip had caused over cooiing and primary coolant depressurizatio However, Section 7.5.1.3 of the FSAR stated that in the event of a reactor or turbine trip while control is in auto, the feedwater pumps are automatically ramped down at a rate of 1.58%

per second to a speed corresponding to the flow required for decay heat The licensee normally operates the system in aut Since operating.

experience indicated that the system w6uld not perform as designed, but instead has ca~~ed overcooling or PCS depressu(ization, the ljcensee had incorporated a step in EOP 1.0 to trip the feedwater pumps after a reactor tri This step was a deviation from the guidelines of CEN-15 For the small break LOCA, three of the five success paths depend upon stea~

generator heat removal, and the licensee's step prematurely securing an operating feed system to shift to an off-line system would decrease the probability of success by reducing success probability for three of the

. five success path The NRC team concluded that the EDP 1.0 deviation to secure main feed would not be required if the system was performing per the FSAR descriptio Either.the original system design failed to conform with the FSAR description, or modifications to the syste~ have caused the system not

  • to perform as designe In the latter case, the 10 CFR 50.59 safety evaluation may have failed to appropriately consider the effects of this system in the determination of *whether an unreviewed safety question existe This issue is an unresolved item (255/89019-01) pending a determination of why the system does not perform as designe. * Technical Adequacy *Review of the Emergency'Operating Procedures (25592)

The Palisades EOPs listed in Attachment I were reviewed to ensure that*

the procedures were technically accurate and could be meaningfully accompli-shed* using existing--equipment, controls, and instrumentatio (I'

  • The inspection team i~entified a number of technical deficiencies, which were addressed to the license These deficiencies along with the licensee's.responses, are listed in Attachment II, and will be,identified as Open Item 255/89019-0 A summary of the technical deficiencies.is presented below:*

The technical deficiencies were found in the follo~ing key areas:

0 Referral to other procedures not adequat Special requirementi to perfor~ a step not being specifie Failure to hav~ piefabri~ated piping/cables/procedures for identifi~d EOP task Preferred instrumentation for parameter monitoring not specifie Degraded containment effects on instrumentation not considere. The. team noted that most EOPs could be improved in the 11 refer to 11 and 11 go to 11 step In* many instances only the procedure number *was referenced and the applicable section number and/or step number of the referenced procedure was not specifie Operator response time and effectiveness would be improved with more detailed p~ocedure referral It was noted, during plant and con~rol room walkdowhs, that the EOPs lacked information about special requirements needed to perform a particular ste On a number of occasions, operators could not perform actions in the EOPs without first racking in a circuit breaker, unlocking a valve, or operating a key switc There were also examples in which room keys, a step ladder, or fuse pullers were required to perform local equipment.operation As in the previous paragraph, more effort in detailing special requirements would ensure timely completion of operator actions in the high stress environment of implementing the EOP During control room walkdown of the EOPs, the team identified several EOP steps_ that required parameter verification without clear direction as to which instrument to monito In several cases where core exit temperature or Tave was being monitored, the EOPs needed to be more specific as to which instrumentation should be used and the limitations for the use of eac The team determined that an extensive effort had been made to incorporate the effects of degraded containment on instrumentation used by the EOP However, in at least one instance, instrumentation accuracy was as~~med to be adequate during degraded containment condition A pressurizer level of 20 percent was one of the conditions required to throttle safety injectio At 20 percent indicated level, with degraded containment, Palisades environ~ental equipment ~ualification (EEQ) analysis shows that actual pressurizer level may be as low as 1 percent (e.g. uncovering most pressuri~er h~~ters). It is possibl~ that a sustain~d lo~s of press~rizer

Cl'

function may result from premature throttling of safety injection.. The Ji censee agreed to.review the fi ndi.ngs of the study of instrument errors..

in a harsh environment, which was in progress under CEN Task 536, and to incorporate appropriate information obtain~d from the review in the EOPs to ensure they wouJd function under harsh environment condition The team identified several tasks in the EOPs that required the use of mechanical or eJectrical jumper However, the licensee did not have procedures for installing the jumpers, and it appeared to the team that, based on the complexity of the tasks, procedures would be appropriat It appeared to the team that the licensee should develop procedures to install these jumper *

The inspectors found the following instances where the procedures required performance of an action step that was not prestage The first involved Step 6.~ of EOP 3.0, which required installation

generator atmospheric dump * The second involved Steps 2.a and 2.b of Attachment 8 of EDP 5.0, which required a ~pecial lineup to transfer a waste holdup tank to a filter waste monitor tank or to a clean w~ste receiving tan The third i~volved Attachment 3, Step 2:c of EOP 2.0, which discussed gravity feed from T-90 to T-The au~iliary operators would use Section 7.5 of SOP 12, 11 Feedwater System, 11 Revision 14, which discussed in general terms the lineup required, but did not identify all of the valves reqaired to be operated, nor was the SOP referenced in the EO The fourth involved the lotation of the attachments-to various EOPs (e.g. status sheets).

Prior to the inspection, the licensee had.

moved the attachments to a file cabinet in the control room and did not inform the operator The operators required some effort to locate the attachment The licensee was encouraged to document all cases that were similar to the a~ove ~xamples and formulate a plan to resolve these deficiencie.

EOP Training (25592)

The inspectors assessed the adequacy of the EDP training by reviewing three area The first dealt with observing an unrehearsed operating crew performing the EOPs on the site-specific simulator with scenarios designed to exercise selected areas of the EOP The operating crew was made up of two licensed operators and two simulator instructor The second. effort was to review lesson plans and training records for the hot licensed and requalification operator training programs as they pertained to EDP trainin Finally, interviews were conducted with selected members of the operations and training staffs_

9 Simulator Scenarios The inspection team developed scenarios*similar to those used for licensed operator exams and the facility's EOP training. These scenarios included:

(1)

A reactor trip with two control rods stuc~ out of the core,

  • l2)

A loss of all AC power, including the diesel generators (D/G),

(3)

A small break loss of coolant accident, (4)

A steam generator feedwater line break inside containment~

(5) *A loss of all feedwater with se~vice water backup available, (6)

A loss of all feedwater with no service water backup (feed and bleed), and (7)

A steam generator tube ruptur~ with concurrent faulted steam generator (radiation release).

buring the performance of these scenarios with the unrehearsed operating crew, the inspection team had th~ opportunity to: assess human factors elements associat~d with the performance cf the procedure~ in a real time" atmosphere; observe how the operators *

diagnose* accident conditions and transition from one EOP to another; assess ~he licensee's operating philosophy; and observe operator performanc The team made the following observations:

0

0

The operators exhibited good knowledge of the EOPs and the CEN-152 guidanc *

The procedu~es generally provided operators with suffitient guidance concernin~ their responsibilities during the emergenci~ *

. The procedur~s appeared to be *organized in su~h i manner as to minimize physical interference between operators when carrying out the actions outlined in the procedure Duplicate operator attions in the procedures appeared to have been mlnimize There appeared to be no formal method used to track continuous action" or "non-sequential steps in the procedures. This presented a potential for overlooking some actions as the operator became involved with a lengthy procedure or when transitioning between procedure *

10 Formal Training Program Lesson plans and simulator scenarios us~d for EOP t~afning were reviewed to verify that the training covered the technical basis for the procedures as well as the structure and forma The following observations were made:

0

There was no formal classroom l~sson plan to cover EOP 3.0,

"Electrical Emergency Recovery," which was issued on August 11, *

198 This EOP had been covered only in a lesson given during simulator training se~slon There ~ere no lesson pl~ns for the individual success path procedures of EOP 9.0, either in the simulator or the classroom phases of instructio *

There was no lesson plan covering "rules of usage" for the EOP Examples of items that should have been included in such a iesson plan are:

definition of common terms such as "available" or "operable"; the meaning and use of "non-sequential" or

"continuous action" steps;-the difference between "referencing" and "branching" to other procedures; and the difference between a "note, 11 "caution," and "warning." There were inconsistencies exhibited by operators in their undetstanding of these areas during the EDP walkdowns and during the simulator demonstration Operations ahd Training Staff Interviews Operators were interviewed to determine their understanding of the EOPs and their responsibilities and required actions, both individually and as* a tea The operators were also questioned to determine if they were knowledgeable of the requirements for tr~nsitioning fro *one procedure to another, and if training was conducted on revised EOPs before-they were implemente The first.training con~ern identified was that there did nqt appear to be adequate training on the actions in the EOPs which were to be implemented by AO The AOs seemed to be unfamiliar with sections of the EOPs that required action on their par Most of the Abs were able to simulate the actions required by the EOPs; however, an inordinate amount of time was require The AOs were unsure of the aim of the procedures and were using a simple "cookbook" approach to the procedure AOs should be able to perform actions in the EOPs in a timely manner to ensure plant safety during the high stress period associated with an emergenc Int~rviews with members of the training staff revealed that there was a formal training program in place for AOs; however, no formal connection was made between the training items in AO lesson plans and action items AOs would be expected to perform as specified in

)

the EOP Many bf the actions AOs would implement which were required by the EDPs were covered by on-the-job training (OJT) item in the initial training journal which new AOs must complete prior to be fully qualified.-

However, not all of the EDP action items to be*

performed by AOs were covered in the initial training program; and not all of the AOs had completed the fqrmal initial training jburna For the AOs who had not formally completed the initial training *

journal, particularly the AOs who had been qualified *before the current program was implemented (more than three years as an AO), an individual evaluation was made by the training staff as to which items in the journal were to be compl~ted by the AO to maintain his proficienc During the-.wa 1 kdowns of the EDP act i ans that were to be performed outside of the control room, the inspectors found that none of the AOs involved or interviewed had been previously trained on the i n-p 1 ant 'actions re qui red by the EDP It was apparent that the AO training program was not being fully implemented to* _

familiarize the AOs with the actions they would be expected to perform under the EOPs,.

The training staff committed to perform a comparison between tr~ining journal OJT items and the EDP action items, and upgrade the training journal to include all AO action items included in the EOP The li~ensee representatives st~ted that particular care ~ould be taken to compare items with~subtle differences between the training jou~nal and the EOP, and these items would be stressed in trainin Action had been taken by the training staff to include AOs in the training sessions to be attended by reactor-operators (RO), so that a more integrated approach to the training would be affecte The training staff also agreed to upgrade the existi~g items in the training journal to state more clearly the relationship between the OJT ite and any applicable EOP action ite The license~'s failure to provide adequate training on the act~ons the EDPs require the AOs to perform is an apparent violation 255/89019-03 of the requirements of Criterion II t6 10 CFR 50, Appendix B, which requires that indoctrination and training of personnel performing activities affecting quality shall be provided as necessary to achieve and maintain suitable proficienc The second training concern was in the area of feedback of changes for the EOPs from the operation's staf A number of operators indicated that they were not aware of the resolution to changes that they had requested" Inefficiencies existed in the current system in that several operators could request the same change over a long period of time, not knowing that the requested change had already been resolve Changes made to an EOP procedure or other procedures should be addressed in the training curri'culum.* Conversely, reasons for not changing a procedure after such a suggestion has been made should be formally provided to the requeste )

l The third training concern was in.the area of training for licensed operators on the EDP base A 11 1 i censed operators_ interviewed

.

indicated that they had received very little training on the basis behind the EDP steps, and the overall strategy employed by the EDP Senior operators further stated that they.saw a need to include ROs in classes that explained the "bi-g picture" in the EDP They stated that most ROs did not know the ~easoning behind the actions in the EDPs, and used a simple "cookbook" approach to the procedure The expressed an interest in increased training in this are A fourth area of concern was simulator trainin The licensed operators stated that most simulator scenarios rarely were carried out to completio They particularly stated that s~ccess path procedures in EOP 9.0 were almost never completed while performing simulator scenarios designed to exercise these procedure In addition, nearly all of the operators stated that they desired more simulator training contact time during the -course of the training yea A third common theme* discussed *with the senior operators was

  • "board time" at the simulato All senior operators interviewed stated a desire to have more time to enhance their control board skills, as opposed to their supervisory skill They 11oted. that one of the responsibilities of a licensed senior operato~ was the ability to.operate all facility controls, if require A fifth concern was that personnel outside the operations department, receJved little or no training in their assigned ta~ks under the EOP For example, instrument and control (I&C) technicians may need to install a jumper to enable equipment operability or mechanical maintenance may need to install a spool piece to enable the transfer of liquid from tank to tan Training on these items would assure proficiency of plant personnel, but also assure that proper equipment was staged for the activit *.The inspectors also found that the operators were weak on the definition of certain key words used in the EDP The words "available, 11 "check,"

11 supplied,

11warning,

11 iritegrated decay he'at removal,

11 and 11 operating

were not consistently understood by the operators~

The inspection team was concerned w-i th the overall qua 1 i ty of training on the EOPs, especially training received by the AO The team concluded that the licensee needs to review the quality of training because of its impact on the ability of the operators to cope with conditions that could exist during an emergenc Resolution of these training related issues will be identified as Open Item 255/89019-0 J On-Going Evaluation of EOPs (25592)

Section 6.2.3. of NUREG-0899 states that 1icensee 1 s *should conside establishing a program for the ongoing evalua~ion of ~DP NUREG-0899 further states that the program should evaluate the technical adequacy of the EOPs in light of operational experience and use, training experience, and any simulator exercises and contra~ room walkthrough Section 6.9.6 of licensee Administrative Procedure 4.06, 11 Emergency Operating Procedure Deve fopment anp Implementation, 11 Revision 1, stated *

that the EOPs shall be periodica.lly reviewed (every 2 years) and listed for review considerations the criteria that were identified in NUREG-089 Section 5.0 of the licensee 1s Administrative Procedure 10.41, 11 Procedures on Procedu~es, 11 Revision 12, delineated the process for initiating a procedure revisio In addition to the formal proc~ss delineated in Procedure 10.41, an informal (not proceduralized) form was use This was ca 11 ed a 11 FORM 40 11 and was used by licensee personnel to identify a potential problem (e.g. a procedure change).

Based on discussions with

. licensee' personnel in the plant, this was the most frequently used method of identifying potential EDP procedure problems. *Form 40 was a three-part memorandum with carbon copies tha~ enabled the individual initiating the

These letters and recent Form 40s were reviewed by the inspectors and provided adequate evidence that feedback was being provide The inspectors were concerned, however, with the disposition of the feedback comment After t~e comments w~re di~positioned, th~ comments were ~estroyed and not retaine Several of the operators interviewed were also concerned that they had not received feedback on their comment The licensee 1 s ongoing review and feedback process needs to be mor~ effectively controlled, and feedback comments need to be returned to the indivi~uals submitting the comment The existing system provided disincentives to the evaluation and feedback proces The inspection team reviewed the involvement and oversight provided by QA in the development, i~plementation, and training on the EOP The inspector found that the QA organization had reviewed EDP 1.0 durihg the de_ve 1 opment stage, and the comments provided by the review were generally editorial in natur The QA review had not included a walkdown of the procedures in the control room or in the plan J The inspectors also revi~wed the audits and surveillances performed by QA for activiti~s related to the_ EOP A QA survej_ll_anc~ was _begun_ i September 1987.arid had a checklist that compared the EOPs to CEN-152, Revision The chetklist included four activities including verification of PGP commitments, compliance ~ith the Writer's Guide, the adequacy of the V&V of the EOPs, and the adequacy of the training*

on the EOP The surveillance was not completed. until July 1989, over two months after the licensee was notified when this NRC inspection

  • would be ~onducted. At this point in time, the EOPs had been revised to conform with Revision 3 (Submittal 2) of CEN-15 The last two items on the surveillance checklist, v.erification of V&V and training, had been deleted from the checklis There was no evidence that any specific audits had been implemented since the initial review of EDP 1.0 in June 198 Audits of training activities at the simulator in 1988 and of operating procedures in 1989 did include some aspects of the EOP However, the training audit involved a review of training reccirds without any observation of the cictual training performed; and the audit of

operating procedures did not include a walkdow~ of the EOPs i~ the control room or in the plant to determine if the EOPs ~ere useable.. As noted elsewhere in this report, the two most significant deficiencies ih the EOP program related to V&V and training, the two areas deleted from the QA surveillanc There was no evi.dence that QA had ever conducted an au~it of the EOPs since the 1986 comments were develope The Ji~ensee's failure to perform ~lanne~ and periodic audits of the Palisades EOPs is an apparent violation (255/89019-05) of 10 CFR Part 50, Appendix B, Criterion XVIIIi which requir~s that a comprehensive syste of planned ~nd periodic audits shall be carried out to determine the effectiveness of the progra.

Human Factors_ (25592)

As a result of the evaluation of the Palisades EOPs, a number of human factors deficiencies were identifie Many of these appeared to be the result of a Jack of specific guidance provided in the EOP Writer's Guide (Administrative Procedure 4.06) or the licensee's failure to tonsistently

. apply the guidance provided therei These deficiencies were also indicative rif the general programmatic fail~re to utilize a multidisciplinary-team in procedure development and revision*, and the* - *

lack of an effective V&V progra Human factors deficiencies are summarized in the following paragraphs, with specific examples provided in Attach~ent 3, and their resolution will be tracked as Open Item 255/89019-0 EOP Structure and Format EDP structure ~nd format should provide for clear presentation of information in a consistent manne Procedure AP 4.06, however, permitted the use of two widely differing formats for EOPs - a

two column format to be used for EOP 1.0 and a single column format to be used for all other EOP This format was reportedly adopted

  • in emulation of the format used in CEN-152, Revision 3 (although the final submittal of CEN-152, Re-vision 3, adopted the two column format for all gehefic guideltnes).

Because bf the predominance of contingency action step*s throughout the Pali sades EOPs, the two col um_n format appears to be the more sui tab 1 e of the two formats currently in us Transitions Transitions are directives to the operator to move within and.between procedure These steps may instruct the operator to concurrently

  • use more than one procedure, or to completely exJt the procedure being used and move into a different procedur An operator may

~lso be required to reference tables, charts, attachments, or non EOP procedure To avoid confusion and unnecessary delays, transitions should be ~inimized. When they cannot be avoided, it is important that the transition directions be clearly and consistently presente * NUREG-0899 states that when transitions are necessary, a method should be used that is quick and creates the least amount of

disruptio Section 6.4.2.g of Procedure AP.4.06 provided direction on referencing and branching to other procedures or step There was no direction provided, however, which indicated when it was required to reference a procedure or ste Consequently, references were not provided for steps or conditions that the EOP writer determined to be generally known or understood by the operator Such information should be provided for use by the operator if necessar Proc~dure AP 4.06 stated that it was acceptable to reference or branch to a procedure giving only the procedure number without including the procedure title, page number, or the section bf the procedure to be execute Most references were found to not contain this informatio At a minimum, references.should direct the operator to.the specific section applicable to the steps called for in the EOP in order to ~liminate any confusion and delays in locating the approptiate step Several Control Operators (COs) and AOs indicated that they would have preferred having this additional information provide Use of Logic Terms Section 6.4.2.b of AP 4.06 stated that logic terms, including AND, OR, NOT, IF, IF NOT, WHEN, and THEN *should be capitalized.and underline In practice', however, all instances of these words were highlighted in this manner even though the contextual use was not as a logic ter For example, the word 11 AND 11 when used as a simple conjunction in a sentence was consistently underlined and capitalize Highlighting of the terms AND and.OR should have peen r~~erve~ for describing 11 necessary 11 (AND) or "sufficient" (OR) conditions of a

logic statemen The term NOT, unless included as part of an IF NOT statement.or condition, also sh-Ould not have been highlighted a~ a logic ter This practice detracted from the effectiveness of the highlighting used to call the operators attention to actual logic statements that required operator decision Paragraph 1 of Section 6.4.2.b of AP 4.06 stated that when four or more conditions need to be joined, a list format shall be use.

While no instances were found where more than three conditions were*

joined by AND in the same sentence, numerous instances were identified where list formats were used which als~ included AND between each conditio By prefacing the list of conditions with a statement indicating that all of the following conditions must be met, in~lusion of these ANDs was extraneous and should have been avoide *It was noted that in other instances where such lists were used, the AND terms were not use *

The terms IF and THEN should have been used to indicate actions to be taken by the operator IF a certain condition existed (as described in paragraph 3 of AP 4.06 6.4.2.b).

In some cases, however, IF/THEN statements were incorrectly used in the procedure to indicate expected plant response IF a c~rtain conditiQn exist Use of IF/THEN as logic terms ~hould have been reserved to those instances where operator actions were require Component Identification Section 6.~.2.h of AP 4.06 described the requirements for identifying components referenced in the EOP Paragraph 2 stated that when engraved names and numbers on panel placards and alarm windows were referred to in the procedure, the engraving s~ould be quoted verbati There were a number of instances where this requirement was not applied in the control roo There were also inconsistencies found between the format of component labels in the plant, and the referenced component ID numbers in the EOPs (e.g., MV779CA vs MV-CA779).

Paragraph 4 of AP 4.0.6 stated that when components were seldom used, or if the component may be diffi~ult to find, location information *

should be provided in the procedure. While location of co~ponents within the control room presented no general problems, significant difficulties were encountered in locating components in the plant.*

On several occasions, AOs experienced difficulties or delays in locating valves and other components referenced in the EOPs, attachments to the EOPs, and SOPs referenced by the EOP In addition to addressing equipment location in AO training, this information should have been indicated in the procedure There were numerous inconsistencies found in the way that component identification was accomplished within the EOP In some cases, only the name of the component was provid.ed. *In other cases;' on*ly the

component ID number was provide When both the name and ID number were provided, there were ir:iconsisten~i.es in th_e order of presentatio and in the use of parenthese The Writer 1s Guide needs to provide more specific guidance 6n the use of component ID numbers and describe a consistent format for presentation of identifying informatio Cautions and Notes Section 6.4.2.c of AP 4.06 described use of cautionary information*

and notes.. No discussion was provided, however, regarding the type of information that should be included in a c~ution statement, and very limited discussion was provided regarding information to be presented in note Instances were found where cautions contained incomplete information (especially regarding the consequences of actions).

Instances were a 1 so found where information was pTesented as a caution that was more appropriate to present as ~not~ and vice vers There were also cases in which information in the form of a note should have been added to the EOP, there were also instances where information that was presented was not actually needed or appropriate to the asso_ci ated step, Sentence Structure and Vocabulary Language used in EOPs should be as concise and direct as possible to min1m1ze potential for operator confusio Sectioh ~.4.3.c of AP 4.06

_stated that words used in the procedures should convey precise understa~ding to the trained ~erson.. In contradictioh to thi~

requirement, however, instances of vagLle, subjective, or indeterminant language were enco~ntered that ~ould require interpretation oh the part of the operato There were also instances of commonly used terms (some of which wer.e defined in the Writer 1s Guide) being interpreted inconsistently by. different operators on different crew There were several instances found of redundant instructions or steps, or inclusion of steps that would never be performed if the operator were to strictly follow the.branching instruction provided in previous contingencj st~p Such steps should have been eliminated as they provided unnecessary clutter and posed a potential source of confusio In-plant Component Labeling and Accessibility To ensure that AOs and other p 1 ant personne 1 could e*ffi ci ent ly carry out their responsibilities in implementing the EOPs, it was-important that components were correctly labeled and easily accessibl In performing in-plant walkdowns of the EOPs and the interfacing procedures, ~number of deficiencies were found.. In several cases,

.components were not labeled, requiring the AO to refer to plant drawings to positively identify the componen A number of instances were found where components were located at heights beyond easy reach of the AO and no ladder was located nearb In one instance, accessibility of the -nearest ladder was also hindered due.to its placement behind a beam with a hose and communications cable hanging in front of the ladder rac Another hindrance to cqmponent accessibility that was observed during in-plant walkdowns was the requirement for AOs to obtain keys from the. control room for operation df certain valves and electrical breaker Although the rationale for such requirements was well

  • founded, there was no i ndi c_at ion in the procedures that a* key was require This information should have been provided (including specific key numbers where applicable) so that AOs could be provided with the needed keys prior to being dispatched to perform local action Operators agreed that in stressful situations, it may be easy to overlook the need for_keys witho~t such a reminde This could result in significant delays in performing local actions, especially if protective clothing was required to enter the are Clarity of Instructional Steps Instructional steps should hav~ b~en more concise and as simple as possibl For equally acceptable steps, the operator should have been directed to carry out one of.the alternatives with the other alternatives provided in the event that the designated step could not be accomplishe There were instances observed ~here the EOPs did not follow thi_s guidance and provided directions for th~ operator to perform one of two or more alternative There were also a number of instances where EOP steps could have been reworded to reduce the number of steps or improve the overall clarit There were some EOP steps that were redundant or unnecessary (for examp_l e, directing.the
  • operator to continue with the next step when following the logic of previous steps would have lead him there anyw~y).-
  • Operator Aids Overall, the flowcharts incorporated into the EOPs (EOP 1, Attachment 1 and EOP 9.0, Attachment 1) were found to be consistent with approved flowchartin~.practic~s and served as useful operator aid Isolated -*

problems ~nvolving improper use of a note and an overly complex statement within a decision box were foun No guidance was provided, however, in AP 4.06 regarding requirements for EOP flowchart To ensure consistency in new.flow charts and.revisions to current flow charts, flow chart requirements should be specified.

. The general format of tables and graphs included as attachments to the EOPs was also found to be in acco~dance with accepted human factors principle No problems with legibility or appearance were observe Isolated problems with labeling of graph axis were observed and are discussed in Attachment II.

Validation and Verific~tion Program (25592)

The inspection team reviewed the licensee's V&V program and the V&V efforts applied to the EOPs and subsequent revisions t6 the EOP The reiults of this review are documented in Attachment IV of this report, and resolution of the deficiencies identified will be tracked as Open Item 255/89019-0 The findings are summarized in the paragraphs below..

As noted in the-previous sections, the walkdowns of the EOPs were generally positive, but deficiencies were noted in the technical adeq~acy of the EOPs and the app l i cat i ans of human f a.ctor Paragraph 3.3.5 of NUREG-0899 states thatL after development, the.EOPs were to undergo a process of V&V to determine that the procedures were technically adequate, addressed both technical and human factors issues, and could be accurately and efficiently carried out. *

~he licensee's V&V program was based upon INPO Guidelines83-004 and 83-006 and was described in the Palisades PGP submission The current program was defined in Administrative Procedure 4.0 The licensee provided documentation to show that the purpose of the verification program was to confirm the written correctness of the EOP procedures~ ensure that GTG and PSTG guidance was properly incarporated into the EOPs, and to verify that application of human factors aspects had been addresse *

The Palisades EOP verification program contained the following elements:

0

.o Quality assurance review for conformance to the Write.r's Guid Technical review to ensure:

Accuracy of the EOP steps, EOP compatibility with operator experience, training and plant hardware, and Identification of EEQ list requirements imposed by EOP equipment usag Control room walkthroughs of the EOPs The licensee also provided documentation to show that the purpose of the validation program was to determine if the control room operators could effectively manage emergency conditions using the EOP Program emphasis was on usability and operational correctnes Validation methodology consisted of the following elements:

Simulator validation Tabl~top validation WalkthrouQh validation The inspection* team reviewed administrative procedures to ensure that adequate controls existed to incorporat~ changes to the EOPs, that the latest revisions.were available to the operators, and that they were easily accessibl Verification and val.idation supporting documentation was reviewed on a sampling basi C.ontrol room, simulator, and plant EOP walkdowns were conducted to ensure that the procedures were validated and verified by the license The inspection team found that the defined V&V proces~ limi.ted QA

  • involvement in the EOP process to a check for Writer 1s Guide conformanc It did not extend to other potential areas of QA involvement such as confirmation of V&V feedback into the EDPs, GTG/PSTG audit and review of deviations, verification that operator action setpoints were available and incorporated into the EOPs, definition of EOP training requirements, verificatitin that preferfed V&V methods were chosen from the available options, confirmation that independent technical reviews were conducted by individuals other than the procedure writer, and EEQ applicabilit The NRC concluded that QA involvement in the EOP process should be extended beyond its present bounds of EOP Writer 1s Guide conformanc This is anothet example of the apparent violation (255/89Dl9-D5) against the requirements of Criterion XVIII of lD CFR 5D, Appendix B, which was cited in paragraph 6 of this repor The Palisades plant specific technical guidelines (PSTG) included four.

administrative procedures, the GTG, the F&TA report, Technical Specifications, existing EOPs, FSAR, EDP related licensing letters, and as-built plant drawing This body of documents is very voluminous and portions of the PSTG are neither plant specific (e.g. _CEN-152) nor technical (e.g. four administrative procedures, the ~riter's Guide, FT&A).

As a result, the PSTG was an unweildy document, which was difficult to verify or validat The inspection team noted some references in the EOPs were incorrectly identified and that the specific training requirements in support of the EOPs were occasionally undefined (e.g. the meaning of "qualified CETs" in the subcooling margin check).

During previous simulator V&V runs of the EOPs, records were made to flag EOP training support requirement However,.

these EDP training support requirements were apparently not communicated to the training organizatio The deficiencies identified in these areas indicated an inadequate V&V program or an inadequately implemented V&V progra The licensee's failure to perform a V&V of the supporting procedures, attachments, and documents to which the EDPs direct or refer the operators, and their failure to

perform the V&V (that which was completed) independent of the procedure writers was a major contributor to the fact that the deficiencies i~entified in this ieport had not been previously identifie A comprehensive V&V process would have enabled the licensee to identify and correct the problems before the inspection team arrive.

Unresolved Items Unresolved ~terns are matters about which more information is required in order to ascertain whether they are acceptable items, violations, or deviation~.

An unresolved item disclosed during the inspection is discussed in paragraph.

Open Items Open items are matters which.have been dis~ussed with the licehs~e. which will be reviewed furth~r by the inspectors, and which involve some action on the pait of th~ NRC or licensee or bot Open items disclosed during the inspection are discussed in paragraphs 4,. 5, 7, and.

Exit Interview (30703)

The inspectors met with licensee representatives (denoted in Par~graph 1)

  • on August 4, 1989, to discuss the scope and findings of the inspectio In addition, the inspectors also discussed the likely informational

Only HPCI feed and bleed and shutdown cooling remai*ned as options and the latter was n6t available until temperature and pressure entry requirements for OHR had been me The NRC team concluded that the EDP 1.0 deviation to. secure main feed would not be required if the system were performing as designe Further,. the team noted that the question was academic for the LOCA inside containment since containment high pressure wduld shut the main steam isolation valves (MSIVs) and thus eliminate the main feed pump However, for the LOCA outside containment, prematurely securing an operating feed system to shift to an off-line system would decrease the probability of success by reducing success probability for 3 of the 5 success path *

that the auto ramp down did not ~erform in accordance with. the FSAR description, that past experience indicated the EDP 1.0 immediate action main feed pump trip was required as a deviation to the CEN~l52, that restoration to design conditions could not be economically justified and stated that the deviation would be retaine Supporting rational was based upon the fact that uhder LOCA conditions, main feed could only be expected to survive for* the small LOCA outside containment and even then it would have to be secured relatively early in EDP 4.0 because of inadequate throttling control or pump steam demand Contribution to coolin CEN-152, Step 4, stated to ensure maximum SI and charging flow, however, this statement was not included in the ED The licensee agreed to add the caution or emphasize the issue in EDP support

Also, the TI located near TI-8929 was not labele ONP-20, Step 4.2.c re~uired the use of a ladder, however, the ladder that was provided outside of Swithchgear Room lC was too long for this applicatio ONP~20, Step 4.6.l required the use of a small ladder, which was not available in the immediate are.

Caut i ans and Notes The caution in EOP 3.0, Step 21 related only to Substep b, but was not so indicate A note should have been added to EOP 5.0, Step 20.c which would alert the health physics technician to the requirement for using a monitoring instrument with a long handle or extension, because the steam lines to be monitored were approximately 10 feet above floor leve The note in ONP 20, Step 4.5.was provided on the page prior to the associated step, and the note and caution provided for this step implied operator instruction The note in EOP 5.0, Step 47 contained instructions for plant restart that were not necessary or appropriate for the operator while in this EO.

Vocabulary Operators differed in their interpretation of the statement "Verify qualified CHs" in EOP 1.0,- Step The number of qualified CETs they would check varied from as few as one to as many-as five, and some said they would printout all of the *value The location of the core matrix from which they were to be selected (some from center or near center, some from perim~ter) was also a source of confusio Some operators.interpreted the statem~nt "Auxi 1 i ary feedwater fl o available" as meaning that flow must be present to meet this condition, and some interpreted it as meaning that power to the auxiliary feed pump breaker was sufficien Some operators defined "Uncomplicated reactor trip" as a trip for which all left hand column steps (conditions of EOP 1.0) had been satisfie Some operators interpreted the statement "Service water available" in EOP 3.0, Step 8, to mean being supplied, while others interpreted it to mean 11 ca*n be supplied if necessary."

  • The "Warning" in EOP 3. 0, Step 12, was not defined in the Writer 1 s Guide, nor was it addressed in lesson plans for operator trainin Many operators indicated that they did not know the meaning of the term

"integrated" in the caution step of EOP 3.0, Step 1 The term "Delta T" in EOP 4.0, Step 42, should be defined for clarity since it does not refer to the usual Th minus Tc.

. Operator Aids The first decision block (PCS SUBCOOLING RISING OR EITHER S/G PRESSURE

< 700 psia?) on page 6 of EOP 1.0, Attachment 1, was identified by operators as being confusing because of the 11 0R 11 and that 11 <

11 had recently been changed from 11>

11 *

This block would be clearer if split into 2 blocks, which would avoid the OR conditio *

,,

The conditional statement on page 8 of EDP 1.0, Attachment 1, included as a note should have been included as a decision block(s) in the -

flowchart structur The pre~entation of the graph in EDP 4.0, Attachment 8, page 1, was not consistent with the convention followed on_ other graphs in this attachment (e.g., input variable on the X axis and output variable on the Y axis).

When questioned, there was a discrepan~y among o~erators on how to use 11 non-sequential 11 step Some operators stated that these *steps could be performed at any time, while others stated that the procedure must be completed up to that step before the step could be completed in a 11 non-sequential manner.

Several operators were confused as to the difference between a 11 non-sequential 11 step and a 11continuous 11 ste The licensee stated that 11 non-sequential 11 and 11 continuous 11 *steps may be performed at any tim The licensee will evaluate the need for such a large number of 11 non-sequential 11 step Alarm panels were indexed in different manne~s on different parts of the control board One set of *panels was indexed from the top left, left to right, and top to botto Other panels were indexed from the

~op left, top to bottom, and left to righ The licensee' representative stated that the alarm resp6nse manuals were written in such a manner as to preclude any performance problems associated with al ternctte indexing method The 1 i censee did not pl an to modify the alarm indexing schem *

ATTACHMENT IV VERIFICATION/VALIDATION DEFICIENCIES Sp~cific detici~hcies regarding of the V&V prbgram are provided belo The licensee committed to evaluate the identified programmatic weaknesse Some examples of V&V weaknesses as evidenced in the EOP procedures are included as illustration It should be _noted' that the deficiericies i.n Attachment II ahd III were not identified during the Pali.sades V&V and, therefore, generally constitute V&V weaknesses as well as technical or human factors item It is also noted that NUREG-1358 was iss~ed shortly before this inspection and the licensee did not have time to review and incorporate its guidance into the EOP upgrade progra Programmatic weaknesses: V&V was not required and had not been accomplished on the EOP ~upporting procedures to which the EOPs refer or transfe * _The V&V process instructions did not require an independent revie Admiriistrative Procedure 4.06, Sections 6.6 and 6.7 described technical reviewer and validation team staffing requirements, but did not include a requirement that these personnel be inde~endent of the EOP procedure

3. * Administrative Procedure 4.06 contained reference to technical notebook(s).

The notebooks were no longe~ being use *

  • Administrative Procedure, Section 6.6 verification requirements did not extend into the plant; only control room walkthroughs were require.

Validation requirements could be met with only simulator validation and without a control room walkthroug To the extent that the simulator differed from the main control room, such a validation may have been 1naccurat.

Paragraph 6.7.2 listed validation methods in the order of simulator, tabletop, and walkthroug This order inferred that the table-top would be preferred to walkthroug.

Paragra~h 6.7.3~a.2 indicated the operations superintendent was responsible for determining if validation was require A minimum requirement for validation should have been stated (e.g., all EOP numbered revisions will be validated).

Specific V&V comments:

EOP * Steps 13 and 24:

Nomenclature differences between plant labels and the EOP were found in the case of 7 valve EOP labeling was MV-WExxx; plant labeling is"MV-xxxWE in Step 13 and MV-CDxxx vs MV-xxxCD in Step 2.

Step 59 b.3.e:

The breaker was normally racked ou The procedure.did not require rack i EOP 4. 0 Steps 4 and 5 were incorrectly sequenced; Step 5 should have appeared first, which was the only way the direct transfer could be made to EOP As written, the operator who had misdiagnosed the LOCA would be delayed in a loop until he was directed to EOP 9.0 by the status check.

Step 13d:

This step should have been related tci PCP CCW flow or particular valves, not to 11 any CCW v.alve isolation valve closed.

It was possible

to have many CCW isolation valves closed without loss of flow to the PCS pump.

Step 49.e:

Valves were transferred to an ~lternate controlle~, not an alternate suppl.. PSTG DEV:

GTG Supplementary Inst~uction 6 required that the operator should be-cautione*d against premature manual RAS initiation, which could lead to insufficient sump inventor No caution was contained in the EOP, no deviation existed, and the item-was not specifically addressed in EOP support trainin.

Attachment 2 pump curves:

Step 29.b labeled the curves as minimum flow requirement The curves *did not indicate minimu In addition, since the four individual meteis upper li~it was 250 gpm, the curves for two pump operation should have stopped at 1000 gp.

Step 12 was interspersed between St~ps 11. c and 13, which evaluate and maintain CCW to the PCS pump.

Step. 50. c:

The second 11 go to 11 transfer should have been to Step 50..

Step 77.f:

The word acceptable was used without definitio Walkdown

_operators were not certain what was acceptabl.

Attachment 8, graph on page 1:

This presentation was contrary to the standard convention, which was followed for all other graphs in this procedure (e.g., input variable on the X axis and output on the Y axis).

The licensee agreed to evaluate this ite EOP 5. 0 SOPs 12 and 13 were rarely used; equipment location was not specifie *

c Some plant components were unlabeled; lack of labeling contributed to delays during AO walkdowns (e.g., MV-VAS 915 and TI-8929.were missing labels; an ID number marker near MV-VAS 915 appeared to read 913) A ladder was required to evaporator boiler roo searching for the ladder delay EOP respons reach Steam Traps ST-8641 and 8928 in the The nearest ladder was two rooms away and contributed to walkdown delay~ and would also Component referencing was sometimes inconsistent (e.g.; MV-118FW was referenced in the procedure as MV-F118; MV-RWS120* as MV-RW 120) Attachment A referred to Step 7.6.1 in SOP 12; the proper step was 7..

Steps 5 and 6 of Attachment 8 identified inlet ~nd outlet valves for Tanks F59 and F6 However, the identification was not uni~ue to particular tan Administrative Procedure 4.06 Paragraphs 6.2.1 and 6.2.2 defined the Palisades PSTG, which consisted of four administrrative procedures, the GTG, the F&TA report, Technical Specifications, existing EOPs, the FSAR, EOP related licensing letters, and as-build plant drawing This was about 30 seperate publications which would stack over 5 feet hig Portions of the PSTG were neither plant specific (e.g., CEN-152)

nor technical (e.g., four administrative procedures, the Writer 1 s Guide, FT&A)~

As a result, the PSTG was an unweildy dotument which was extremely cumbersome to use effectivel *

The NRt team ~oted that this deficiency had little impact on success of the program, principly because the entire development program was accomplished by a few well qualified individuals whose span of control extended to all facets of the progra However, in the event of a significant proces~ or staffing change, the lack of a consolidated PSTG could inhibit the progra '"
