EXECUTIVE SUMMARY Clinton Power Station NRC Inspection Report 50-461/98014(DRP)
This inspection included aspects of licensee operations, engineering, maintenance, and plant support. The report covers a 6-week period of resident inspectio Operations
. The inspectors noted that operator performance improved with respect to questioning degraded or suspect indications, taking conservative immediate actions, and initiating the appropriate corrective action document. The performance improvement was due, in part, to implementation of the operations department event free performance initiative (Section 01.1).
- The inspectors determined that the licensee's Generic Letter 91-18 program for operability determinations (ODs) was not effective in ensuring ODs were dispositioned in a timely manner. Specifically,28 of 41 active ODs describing nonconforming conditions were older than 6 months. Actions taken in May 1998 to disposition the active ODs were not successful in that only one of five shift managers had completed the review of assigned ODs by August 1,1998 (Section O2.1).
- Operations personnelimplemented nonconservative compensatory measures for a I potential fault condition affecting the Division i Nuclear System Protection System (NSPS) inverter. Specifically, operations personnel viewed declaring a faulted component administratively inoperable as an adequate compensatory measure even though leaving the faulted NSPS inverter energized could potentially introduce complications with the power supply (Section O2.2).
. Operations personnel did not recognize a potential reduction in ultimate heat sink inventory as a condition requiring an OD or mode restraint (Section O2.3).
. As a result of the corrective actions that were implemented to improve performance in the safety tagout program, including providing additional staffing, increasing management oversight, and improving training for operations and maintenance personnel, tagout events were reduced from 11 in 1997 to 3 as of August 1,1998
'
(Section O2.4).
. The inspectors' review of the operations department self-assessment program revealed that, between January and July 1998, it did not have a stable program owner to oversee completion of self-assessments, weaknesses identified in operator radiation work practices were not addressed, and recommendations and weaknesses described in the radiation worker practice and quarterly assessment reports were not tracked or assigned a responsible owner. These findings were indicative of the need for improvement in the operations department's formal self-assessment program (Section 07.1).

D l lt l
[ Maintenance
- The inspectors concluded that the licensee's revised molded case circuit breaker testing program conformed to the latest NRC and industry guidance (Section M1.2).
- Although the Division ll emergency core cooling system (ECCS) integrated
, loss-of-offsite-power and loss-of-coolant-accident surveillance testing was completed
'
without complications, the preplanning for the test could have been more thorough. For i example, some personnel assignments were initially made and/or changed at the briefing, communicetion links were not established ahead of time, the placement of test cables created a tripping hazard, mechanical stops were not used on open cabinets,
,
and test switches were installed inside energized panels. Additionally, the prejob brief did not include lessons leamed, industry experience, or contingencies (Section M1.3).
'
- The inspectors noted that management expectations were not met during the review of selected condition reports (CRs)in that maintenance personnel did not determine and document the extent of the condition associated with some level three CRs
'
(Section M7.1).
- The inspectors identified a weakness with the sche'duling and completion of Technical l Specification Surveillance Requirements (SRs). The identified issues included:
] 44 percent of all monthly and quarterly surveillances were being performed in the
,
25 percent grace period after the due date; 11 overdue Technical Specification SRs were omitted from a weekly surveillance test report; personnel were unaware of the safety-related preventive maintenance (PM) tasks that were required to meet a specific
.
'
Technical Specification SR; and, the impact on Technical Specification SRs was not evaluated for a late safety-related PM task (Section M8.1).
Enaineerina
- Engineering personnel did not provide adequate support to operations personnel in that a CR addressing an already resolved issue was not closed in a timely manner (Section O2.2).
- One violation was identified for which enforcement discretion was exercised. The inspectors identified that Technical Specification requirements were not met because the Division ll! EDG cannot automatically switch during surveillance testing from the test ,
(droop) mode to the isochronous mode as required in response to an actual or simulated emergency core cooling system initiation signal. This item is of concem because the Division 111 EDG test conditions were such that the high pressure core
,
spray (HPCS) pump, which is powered by Division Ill, would not have been able to
-
supply the required flow to the core if a valid HPCS signal was received while the EDG was being tested. Also of concem is that the licensee did not recognize that the design of the EDG resulted in the inability to meet a Technical Specification requirement
,.
(Section E8.6).

Plant Support
. Yhe licensee's self contained breathing apparatus inspection program was thorough in that inspections were performed at the proper frequency, all material condition and .
l functionality issues were addressed, and appropriate actions were takan when test
! failures were identified (Section R1,1).
,
. In preparatiot for the installation of a fire separation wall, the licensee removed a
'
2-inch suppression pool cleanup line which resulted in an estimated 28 person-rem dose savings for the modification. This demonstrated effective implementation of the l As Low As Reasonably Achievable (ALARA) program (Section R1.2).
!
! . The inspectors determined that emergency planning personnel had not verified the l capability to staff emergency response organization positions following a failure of the autodialer pager system even though there had been four failures of the pager system since July 1997 (Section P1.1).

The inspectors reviewed operator response to various plant condition Observations and Findinas Degraded Fuel Pool Cooling (FC) Pump l l In February 1998, engineering personnel initiated Condition Report (CR) 1-98-02-228 to l document an issue involving the set point for component cooling water flow Switch 1FIS-CC191A(B). Operations personnel determined that the reliability of the i FC pumps was in question because it was not known at what level belaw 10 inches of water column the pumps would trip. Operations personnel determined that the pumps remained operable provided a manual operator action was taken within 5 minutes to ensure the pumps tripped following a loss of component cooling wate I On July 6, during a review of main control room deficiencies, the inspectors questioned how the FC pumps could remain operable given the limited time for manual operator action following a loss of component cooling water. Operations personnel reevaluated the issue and declared the FC pumps inoperabl On July 7, the inspectors noted that an entry had not been made in the control room station log to annotate that the FC pumps were inoperable, even though a log entry had been made in the shift manager's log reflecting the change in FC pump statu Operations personnel updated the control room station log to correct the omissio On July 20, operations personnel initiated CR 1-98-07-238, to document that the operability of the FC pumps had not been properly assessed in February 1998, and that no system currently existed for statusing equipment important to safety unless it had a limiting condition for operation (LCO) specified in the TS, operational requirements manual (ORM), or off-site dose calculation manual (ODCM).

,o inspectors noted that the change in the operational classification of the FC pumps and the initiation cf the CR regarding the program deficiency in statusing equipment important to safety, were reflective of improvement initiatives involving event free performance in the operations departmen ERAT Outage Configuration On July 21, on shift operations personnel noted that an approved maintenance activity proposed an ERAT outage configuration which was not in accordance with the Updated Safety Analysis Report (USAR) and did not allow the activity to proceed, questioned engineering and work management personnel on the validity of the configuration, and documented the issue in CR 1-98-07-265. In response to the issue, the licensee developed an altemate method to accomplish the maintenance activity while meeting the requirements specified in the USA Conservative Operator Action Following Spike in EDG Indications On July 22, during surveillance testing, operations personnel observed a spike in the output watts and output current on the Division l EDG and immediately secured the EDG. Operations personnel declared the EDG inoperable and initiated a CR to resolve i
the issu identification of Main Control Room Deficiencies Betweef July 6 - August 10,1998, operations personnel identified 93 new main control room deficiencies.. During the same period,71 main control room deficiencies were closed. The increased identification of suspect indications resulted in the assignment of additional control and instrumentation resources to work down the backlog of main control room deficiencie Control Room Station Logs The inspectors questioned operations personnel regarding the status of corrective actions for three deficiencies described in the control room station log. Two deficiencies, an EDG ventilation fan failing to start and a station air valve failing to fully close during post maintenance testing, were appropriately documented in the station log and condition reports were initiate The third deficiency identified the potential for intermediate range Monitor H to " hang up" on withdrawal. Operations personnel appropriately documented the issue in the station log; however, a condition report or mode restraint was not initiated to track the discrepancy. Following discussions with the inspectors, operations personnelinitiated a mode restraint and a condition report to ensure resolution of the issu . - - - - _ . .- - -, .

e Inspection Scope (71707 and 37551)
The inspectors performed a review of active operability determinations (ODs) using the guidance provided in Generlc Letter (GL) 91-18, Revision 1, "Information to Licensees a
Regarding NRC Inspection Manual Section on Resolution of Degraded and ;
'
Nonconforming Conditions." Observations and Findinos The inspectors noted that Procedure 1014.06, " Operability Determinations," was j
. consistent with the guidance provided in GL 91-18. Revision 1. However, the l inspectors noted that approximately 41 active ODs were in place as of August 1,199 ;
The inspectors reviewed the active ODs to determine if safety evaluations or corrective ;
actions had been performed when required. The inspectors noted that active ODs ;
existed for components declared inoperable by the operations department and that for j at least 15 active ODs safety evaluations had not been written to address the !
'
nonconforming conditions that were the subject of the ODs. The inspectors also noted that the nonconforming conditions described in the active ODs were not dispositioned in a timely manner. Specifically, 5 ODs were open greater than 18 months, an
!- additional 5 ODs were open greater than 12 months, and 18 ODs were open greater than 6 month The operations manager informed the inspectors that a review of the OD program had been initiated as part of the Plan For Excellence in May 1998. As part of the review, ODs were divided among the five shift managers. The shift managers were tasked with l determining if the ODs were ready for cicsure based on actions completed to date or determining the actions necessary to close each OD. On August 1, the inspectors noted that only one shift manager had determined the status of the ODs assigned for revie Following discussions with the inspectors, operations personnel determined that 12 of the 41 ODs remained active, even though the corresponding condition report had been closed, and initiated actions to close the affected ODs. Additionally, a review of each OD was initiated to determine if a safety evaluation was required, whether or not the USAR needed to be revised to reflect the existing plant condition, and whether or not appropriate corrective actions had been taken or planned. The operations manager

stated that prior to restart of the facility, nonconforming conditions described in ODs would either be corrected or an approved safety evaluation would be processed for a compensatory action or acceptance of the condition, Conclusions The inspectors determined that the licensee's GL 91-18 program for ODs was not effective in ensuring ODs were dispositioned in a timely manner. Specifically,28 of ,
41 active ODs describing nonconforming conditions were older than 6 months. Actions l
'
taken in May 1998 to disposition the active ODs were not successful in that only one of l five shift managers had completed the review of assigned ODs by August 1,199 .2 Implementation of OD for Division I and ll Nuclear System Protection System (NSPS)
Inverters Inspection Scope (71707 and 37551)
The inspectors reviewed implementation of OD 198-02-525 involving the placement of the Division i NSPS inverter in the maintenance bypass positio I Observations and Findinos Condition Report 1-98-02-525 was initiated on February 27,1998, to document a potential fault pathway between the station ground and instrument ground when the Division I and 11 NSPS busses were aligned to the maintenance bypass position. The fault pathway was identified during a system design and functional validation (SDFV) i review of engineering change notice (ECN) 28519, which had been initiated to make wiring changes to the NSPS inverter maintenance bypass switc Following initiation of CR 1-98-02 525, the originator of the CR was provided with l
ECN 28997, which was initiated to resolve the grounding concern created by l ECN 28519. Specifically, ECN 28997, which was implemented in April 1995, modified l the circuit to relocate the ground point connection for the low side windings of the regulating transformer so that the transformer would be separated from the ground point when the circuit breaker was opened. Even though the fault condition did not exist and in spite of the ECN documentation, the CR was issue On June 23, during a review of CRs, operations personnel noted that CR 1-98-02-525 remained open. Operations personnelinitiated OD 1-98-02-525 and transferred the concerns described in CR 1-98-02-525 to OD 1-98-02-525 without requesting assistance from engineering personnel. The inspectors noted that the untimely (approximately 5 months) resolution of the CR by engineering personnel resulted in the unnecessary development and implementation of compensatory actions by operations personne The CR and OD described that if there was a fault when the inverter was aligned to the bypass position, transient noise affecting plant instrumentation, inadvertent engineered safety feature (ESF) actuations, or the failure of necessary ESF equipment to actuate

%
e could occur. The compensatory measure described in the OD for aligning the NSPS inverter to the maintenance bypass position, was to declare the associated NSPS distribution system administratively inoperable and implement the required TS action The inspectors noted that the Division i NSPS inverter was aligned to the maintenance bypass position on July 23 and 24. During this period, operations personnel aligned what they believed to be a faulted component to the safety-related busses creating the potential for the previously described problems to occur. The inspectors considered the compensatory measures in the OD nonconservative in that declaring the NSPS !
distribution system administratively inoperable did not address the p ' problems associated with a faulted componen l On August 4,1998, the licensee determined a drafting error had incorrectly specified

.the location of the ground on USAR Figure 8.3-2, "NSPS Power Distribution," for the Division ll maintenance bypass feed, initiated corrective actions to revise the affected drawings and figures, and closed OD 1-98-02-52 ' Conclusions Operations personnel implemented nonconservative compensatory measures for a potential fault condition affecting the Division i NSPS inverter. Specifically, operations l personnel viewed declaring a faulted component administratively inoperable as an adequate compensatory measure even though leaving the faulted NSPS inverter energized could potentially introduce complications with the power suppl Engineering personnel did not provide adequate support to operations personnel in that a CR addressing an issue that had already been resolved was not closed in a timely ;

The inspectors reviewed circumstances surrounding a nonconforming condition involving a loss of inventory from the Ultimate Heat Sink (UHS) under certain accident condition Observations and Findinas
.
On July 10,1998, engineering personnel initiated CR 1-98-07-130 to document that during an accident involving the loss of the Clinton Lake Main Dam, approximately 10 gpm of cooling water for the post-accident sampling system would be supplied via the shutdown service water system from the UHS, and then be rejected via the plant service water system, which does not discharge to the UHS. Updated Safety Analysis Report, Section 9.2.5.2, " Ultimate Heat Sink System Description," described the potential losses from the UHS but did not include a description of the 10 gpm supplied to the post-accident sampling syste i 9 l

..
The' inspectors discussed the issue with operations personnel on July 27 and 28. Operations personnel initially stated that since TS 3.7.1, " Division 1 and 2 Shutdown Service Water (SX) and Ultimate Heat Sink (UHS)," did not require the UHS to be operable in Mode 4, no OD was required and that resolution of the issue would be a mode restraint for startup. However, the inspectors noted that the item had not been )
added to the mode restraint lis ' On July 29, operations personnel re-evaluated the documentation associated with the reduced UHS inventory issue, concurred with the inspectors that a nonconforming I condition existed, and performed an OD to assess whether the UHS could perform its L intended safety function with the additional lost inventory.
I Conclusions L
Operations personnel did not recognize a potential reduction in UHS inventory as a l nonconforming condition requiring an OD or mode restraint. Following prompting by
! the inspectors, operations personnel initiated an OD to assess whether the UHS was capable of performing its intended safety function during accident conditions.
l O2.4 Taaout Prooram lmolementation Insoection Scope (71707)
The inspectors reviewed the tagout program to determine the effectiveness of changes
made to the progra Observations and Findinas CPS Safety Tagging Program
<
I On July 22,1998, the inspectors noted what appeared to be an increasing trend in the number of tagging related errors. The inspectors attended a condition review group (CRG) meeting associated with a tagging related error and noted that the licensee did not discuss or identify an emerging trend associated with tagouts. The corrective action group manager stated that the CRG was not chartered to identify trends involving CRs and that each department had the responsibility to identify emerging and adverse trends during the CR review (see Section M7.1).
W The inspectors noted that the licensee had initiated 17 CRs describing various tagging l
related deficiencies since January 1998,9 of which were initiated between July 1 and August 10. A tagging error was defined as a tagout situation which compromised a barrier's effectiveness. Examples of tagging related errors occurring in July and August of 1998 included: four examples of not signing or initiating tagging sheets, three p examples of not performing voltage checks on 480 Vac molded case circuit breakers, j using an incorrect revision to a tagging sheet, and hanging a caution tag on the wrong switch. Additionally, CR 1-98-07-181 was initiated on July 15 to document the failure to l
- perform safety evaluations for active tagouts greater than 6 months old and CR 1-98-07-358 was initiated on July 30 to document an increase in dislodged tags.

.. 1 Following inspector discussions with operations personnel, a lower threshold for initiation of a tagging program review was established. The use of the lower tagging error threshold resulted in operations personnelinitiating a review of the tagging '
program, in spite of the recent increase in tagging errors, the inspectors noted that the number of tagging events, a situation where work was authorized to proceed without an adequate j tagout, had substantially decreased in 1998. In 1997 there were 11 tagging events and 33 tagging errors. As of August 1,1998, there have been 3 tagging events and 14 tagging errors. The inspectors attributed the reduction in tagout related deficiencies to corrective actions involving a complete revision to the tagging procedure, increased training of operations and maintenance personnel, additional verification of tagout adequacy by personnel signing a tagout, increased staffing of the tagout group, an increased lead time for tagout requests from 1 day to 2 weeks, and increased oversight of tagging issues by licensee managemen Illinois Power Dispatch Safety Tags
~
l On July 31, the inspectors observed the relocation of the ERAT transfer switch as part of the ERAT modification. During the transfer, a CPS site safety department representative found a dislodged Illinois Power dispatcher safety tag and gave the tag
- to the CPS project manager. The project manager realized where the tag was i supposed to be placed and reinstalled the tag on the disconnect switch ratchet j mechanis l The inspectors questioned the two CPS individuals about the appropriateness of l reinstalling the safety tag without operations department assistance. The project !
manager requested the assistance of the project engineer (an Illinois Power employee working out of the corporate dispatch office), who stated that the safety tag was controlled by corporate procadures, that notifying CPS operations personnel per the site procedure was not required, and that it is common practice for personnel in his position to manipulate safety tagged equipment as necessary to complete assigned task The inspectors questioned the operations manager on the control of dispatcher safety tags. The operations manager stated that it was his expectation that the main control room be knowledgeable of occurrences involving safety tags and that the activity would be used as a leaming experience, and ensured that a CR was initiated to document the even The inspectors reviewed Procedure 1014.01, " Safety Tagging Procedure," and noted that the CPS site specific procedure made reference to Corporate Procedure EO 3.14,
,
" Transmission and Sub-Transmission Systems, Electric System Switching" for dispatcher tagging. The inspectors noted that Procedure EO 3.14 did not provide guidance on the reinstallation of dislodged safety tags. Additionally, Procedure EO 3.14 provided minimal guidance on when notification should be made to CPS operations personnel during the installation and removal of safety tags by

'
c. Conclusions As a result of the corrective actions that were implemented to improve performance in l the safety tagout program, including providing additional staffing, increasing management oversight, and improving training for operations and maintenance personnel, tagout events were reduced from 11 in 1997 to 3 as of August 1,199 However, the authorization for corporate dispatch personnel to hang and remove safety

07 Quality Assurance in Operations l 07.1 Operations Department Self-assessments a. Inspection Scope (71707)
The inspectors reviewed operations department self-assessments completed between January and July 1998.
l b. Observations and Findinos
! Self-assessment Schedule The latest schedule for operations formal and informal self-assessments was approved on September 30,1997, by the former operations manager and did not reflect current or planned self assessment activities. In response to the inspectors' observation, operations personnel formulated a new self-assessment schedule on August 5,1998, which included restart readiness reviews, plan for excellence action reviews, and program effectiveness reviews in response to identified deficiencies in risk management and safety tagging. The new schedule did not include ongoing informal self-assessment activitie The inspectors noted that several restart readiness reviews were in progress but that only one formal self-assessment (radiation worker practices) had been completed in the operations department between January 1 and July 31,1998. Informal assessments performed by operations personnelincluded the ongoing safety tagging monitoring program and the station operations monitoring program. Participation in the station operations monitoring program had decreased due to development and implementation of the operations department event free performance initiative. As noted in Section 01.1 of this report, the event free performance initiative has increased operator l
awareness of suspect plant indications.
l The inspectors noted that four formal self-assessments specified on the September
1997 schedule were assigned to individuals no longer in the operations department.

Operations personnel stated that the affected assessments had been incorporated into l the Plan For Excellence schedule.
Operations personnel stated that the schedule had not been updated, in part, due to tumover in the operations department self-assessment coordinator position. Since January 1998, four individuals have been selected as the self-assessment coordinato l The frequent tumover resulted in reduced oversight of program implementatio '
l Radiation Worker Practices Self Assessment The inspectors reviewed operations department self-assessment OPS-98-064, dated L
'
April 27,1998. The assessment was initiated in response to an adverse trend associated with operator radiation work practices. The inspectors noted that the l assessment did not use personnel assigned to the radiation protection department to
- assist in the review and that the evaluation guide did not assess the use of survey instruments by operations personne '
The discussion section of the assessment described a weakness involving posted surveys. Based on the assessment, the licensee determined that most operations
.
personnel were unaware that the surveys did not include the weekly reference point l survey data. However, no corrective actions, recommendations, or CRs were initiated to resolve the weaknes Three recommendations were made regarding placement of exit terminals, purchase of shoe covers, and a semi-annual performance of an operations department radiatic'
worker practices self-assessment. The inspectors questioned operations personnel to determine how recommendations and weaknesses documented in self-assessment reports were tracked and resolved. Operations personnel stated that items identified in the radiation worker practice self-assessment and the operations department quarterly report had not been placed in a tracking system or assigned to a responsible individual for resolutio The inspectors noted that CR 1-98-06-246 was initiated on June 19,1998, to document the failure of operations personnel to track recommendations documented in the late 1997 " Utilization of Operations Resources," formal self-assessment. In response to the CR, operations personnel determined that the recommendations were tracked via the
'
Plan For Excellence. However, a review to determine whether or not other self-assessments were similarly affected was not performed. Consequently, the licensee missed an opportunity to identify the failure to track weaknesses documented in other operations department self-assessment The inspectors noted that the licensee's failure to implement corrective actions for deficiencies identified in self-assessments was the subject of an NRC Notice of Violation (50-461/98008-05, issued June 25,1998) for which enforcement discretion was exercised in accordance with Section Vll.B.2 of the enforcement policy. The inspectors noted that the licensee's corrective actions for this violation had not been
,
fully implemented at the end of the inspection period. This violation constitutes an l additional example of NCV 50-46198005-05 and is not being cited individually. Further i

corrective actions for this additional example are expected to be taken in conjunction with corrective actions for the previous violatio In response to the observations, the licensee stated that the radiation worker performance assessment would be re-performed. However, when the new self-assessment schedule was approved in August 1998, it did not include a radiation worker practices self-assessmen Conclusions
' The formal operations department self-assessment program did not have a stable program owner to oversee completion of self-assessments, weaknesses identified in the radiation worker practice assessment were not corrected, and recommendations and weaknesses described in the radiation worker practice and quarterly assessment reports were not tracked or assigned a responsible owne Miscellaneous Operations issues (92700 and 92901)
08.1 (Closed) Notice of Violation 50-461/96412-06: Failure to notify chemistry personnel of a reduction in power so that a gaseous sample could be obtained. This item was originally described in NRC Inspection Report 50-461/96010. Initial corrective actions involved, in part, development of a management observation program to improve supervisory oversight, training on procedural compliance, and discussions of when chemistry samples are required. Subsequent to the violation response, the licensee has initiated several human performance improvement initiatives described in the Plan For Excellenc .2 (Closed) Notice of Violation 50-461/96412-10: Failure of the shift technical advisor j (STA) to assist the shift supervisor during an Unusual Event. This item was previously i
described in NRC Inspection Report 50-461/96010. In response to this violation, the licensee counseled the STA on required duties and adherence to procedures. In addition, the licensee conducted expectations training and seminars addressing this issue, similar human performance errors, procedure adherence, and conservative decision making. Inspection Report 50-461/98009 identified that an STA performed the initial off-site notifications during an event when a non-licensed operator was unable to accomplish the actions. The inspectors planned to review the licensee's revised corrective actions for this issue as part of the closeout activities for inspection Fe v-up Item 50-461/98009-0 .3 (Closed) Notice of Violation 50-461/97022-01and inspection Follow-Up l

The licensee issued a complete revision to Procedure 8410.04, " Molded Case Circuit L Breaker Functional Testing and Maintenance," on August 7,1998, and procured new
test equipment in response to a violation for the failure to establish a test program to
'
ensure 480-Vac MCCBs will perform satisfactorily in service (NCV 50-461/98011-06).
The inspectors confirmed that Procedure 8410.04, Revision 11, and the vendors test equipment manual met the latest industry guidance with the exception that a single wire size is not specified for each breaker rating, The electrical maintenance manager stated that a " minimum" wire size had been retained in the procedure because the new test equipment would not supply enough current to the MCCB when the industry recommended wire size was used. The licensee determined that the time for a breaker trip would be longer with a larger wire size; therefore, if a breaker met the acceptable trip times with a larger wire, it would pass with the smaller industry specified wire siz i The licensee completely revised the MCCB testing method and Procedure 8410.04 was expanded to include testing the MCCB bucket (the frame that holds the MCCB's, related auxiliary contractors and relays for insertion into electrical distribution panels).
The initial results of the testing revealed several discrepancies in the buckets teste As of August 13, insufficient results were available to draw a meaningful conclusion about the material condition of the breaker buckets. The number and safety significance of the findings of the licensee's MCCB testing program will continue to be evaluated under NRC Manual Chapter 0350 Case Specific Checklist item IV.3,

b. Observations and Findin.gs The inspectors attended the infrequent surveillance briefing for the loss-of-offsite-power (LOOP) and loss-of-coolant-accident (LOCA) portions of Procedure 9080.22. The test coordinator (TC), with the assistance of the shift manager, covered the purposes of the testing, what equipment would be involved, expected actions, and use of three-way communications. However, the TC did not discuss what the test was intended to prove, the acceptance criteria, lessons leamed from previous tests, or industry experienc The TC covered personnel assignments but several had to be changed during the briefin Although the testing was successfully completed without complications, the inspectors noted the following issues during the test: cables were installed through open back-panel doors without having a mechanical stop to prevent pinching the wires; two separate test initiation switches were installed deep within two separate energized panels, creating a personnel hazard to operate the switches; and, bundles of test
'
cables were run along the floor, creating a tripping hazard. After discussion with the shift manager, stops were installed in the open back panel doors. In addition, immediately prior to starting the test, the licensee discovered that the sound-powered phones were not hooked up or functioning properly. The TC eventually devised a workable communication system using both sound-powered phones and vert)al communication Conclusions Although the Division 11 ECCS integrated LOOP and LOCA surveillance testing was completed without complications, the preplanning for the test could have been more thorough. For example, personnel assignments were initially made and/or changed at the briefing, effective communication links had not been established ahead of time, the placement of test cables created a tripping hazard, mechanical stops were not used on open cabinets, and test switches were installed inside energized panels. Additionally, the prejob brief did not include lessons leamed, industry experience, or contingencies.

- inspectors initiated a review of TS surveillance scheduling and test performance, which included the crediting of safety-related preventive maintenance activities in satisfying TS surveillance testing requirements and tracking of overdue (greater than 1.0 but less than 1.25 times the due date) and late (greater than 1.25 times the due date)
surveillance tests. The licensee applied the same definitions for overdue and late to PM activitie The inspectors identified that 44 percent of all monthly and quarterly surveillance tests were performed within the 25 percent grace period,11 overdue TS SRs were not included in a weekly surveillance test report, personnel were not knowledgeable of which safety-related PM tasks were required to meet a specific TS SR, and reviews were not performed to determine the impact of a late safety-related PM on TS required

SR The inspectors compared the last performance date of monthly and quarterly TS SRs for Mode 4 operations to the scheduled due date and noted that 13 of 29 monthly
'- surveillance tests and 16 of 36 quarterly surveillance tests were performed within the 25 percent grace period. During discussions with work management personnel, the inspectors noted that a recently revised surveillance test report, which listed late and
overdue surveillance tests, did not account for 11 TS surveillances that were within the d grace period. Specifically, once a TS SR was placed on the weekly schedule, it was removed from the surveillance test report. Consequently, TS SRs which were not completed during the assigned week and subsequently carried over on the next weekly schedule were not tracked as being within the grace period since the assumption was i- that the item had been completed as scheduled.

Work management personnel informed the inspectors that the status of safety-related l PM tasks was tracked; however, reviews to determine whether or not a late or overdue i PM task impacted TS SRs was not performed. Additionally, a list of safety-related PM tasks that were required for a specific TS SR did not exist.. At the end of the inspection
,
period, the licensee was performing a review to determine which safety-related PM l tasks were being credited for satisfying TS SRs, and whether or not the late l performance of a PM task could have impacted the TSs.
l On July 30, work management personnel informed the inspectors that their findings l reflected a setback in licensee performance regarding the scheduling and performance of surveillance tests and stated that several corrective actions were being developed
- and implemented. Corrective actions included
- assignment of additional resources to
!
monitor the completion of TS SRs and PM tasks, modifications to a computer database
, used to trend and track completion of TS SRs, modifying the weekly schedule to

! performed prior to their respective late dates. Between May 1 and August 1,1998, eight CRs were initiated to document missed or late performance of TS , Operational Requirements Manual , or Offsite Dose Calculation Manual-required SRs. The inspectors verified that CR 1-98-07-184, documenting an emerging trend, had been initiated on July 15 and that a review to determine the cause and corrective actions for l the failure to perform SRs had been implemented.

This issue was previously reviewed onsite and documented in NRC Special Inspection Report 50-461/97020. The licensee determined that this event occurred due to a breakdown in the control of the consumable materials program, poor management
'
oversight, inadequate post-maintenance testing, and weaknesses in maintenance training. Due to the use of inappropriate soldering flux, approximately 600 main control room neon indicator light sockets were replaced. Prior to performing the rework, the electricians were trained on the proper methods of soldering, prefabricating and installing the light sockets, as well as performing post-maintenance testing. No additional concems were identified during the observations of soldering training. The inspectors reviewed enhancements to the control of consumable materials program to ensure that adequate guidance on the use of soldering flux was provided and that requirements were in place for maintenance planning personnel to verify the appropriateness of a material for use in the plant prior to the material being installed.
' No additional concems were noted with the control of soldering flux. Specific deficiencies regarding poor management oversight were also corrected prior to commencing rework activities.

The inspectors reviewed the design bases of the starting air system for the Division I, ll, and Ill,EDG Observations and Findinas Technical Specification Bases Section 3.8.3 specified that each EDG has an air start system with adequate capacity for five successive start attempts of the respective EDGs without recharging the air receiver and that the EDGs are capable of multiple successive starts without recharging the air receiver tank when the air receiver pressure is below the rated air pressure but above 200 psig. The inspectors questioned whether or not the starting air system must be capable of supporting five successive start attempts from the air compressor pressure shutoff set point of approximately 250 psig or from the lower TS limit of 200 psig. Engineering personnel stated that the air receivers were required to have the capacity to support five successive start attempts from 250 psig and multiple starting capability from 200 psi The inspectors consulted with NRC personnelin the Office of Nuclear Reactor Regulation (NRR) and Region 111. Personnel in NRR agreed with the licensee's view that the air receiver must provide sufficient capacity for five start attempts from the air compressor pressure shutoff set point of 250 psig. Additionally, the air receivers must be capable of two or more (multiple) start attempts from the lower TS value of 200 psi The inspectors reviewed startup testing data for EDG successive start attempts and noted that the EDGs were capable of two or more start attempts from approximately 200 psi Conclusions

! E8.4 (Closed) Notice of Violation 50-461/97011-14 and LER 50-461/97-029: Failure to
! evaluate additional stresses caused by the securing of scaffolding to safety-related L piping. Based on an onsite review of this issue, the inspectors determined that the
! violation was caused by inadequate implementation of Procedures 1019.05, " Control of
! Transient Equipment / Materials," and 8901.10. " Scaffolding Erection /Use/ Dismantling."
'
l Specifically, the procedures did not require that an engineering evaluation be l
performed to address changes in seismic loading when scaffolding was supported by
'
! safety-related piping 4 inches or greater in diameter. In response to this issue, the l licensee revised each procedure such that an engineering evaluation was required when scaffolding was supported by safety-related equipment. A subsequent walkdown ,
l of erected scaffolds resulted in those scaffolds supported by safety-related piping being I l removed, attached to other acceptable points, or evaluated by engineering personne The inspectors performed a follow-up walkdown and reviewed applicable scaffolding I engineering evaluations. No additional concems were identifie E8.5 (Closed) Inspection Follow-up item 50-461/97999-01: Failure of EDGs to achieve rated frequency during surveillance testing. This item was initially identified during the NRC SET inspection performed between September and December 1997. The SET l reviewed surveillance test data and questioned the operability of the Division ill EDG l
since, on one occasion, the frequency of the EDG momentarily dropped below the l
minimum value required by TS after the 12-second time period had elapsed. The licensee stated that the EDG was operable and that it was in compliance with TS
,
SR 3.8.1.7 since EDG frequency met the acceptance criteria specified in the TS within 12 seconds. The system engineer provided information which stated that momentary overshoot and undershoot of EDG voltage and frequency was expected when the EDG l
was not connected to its safety-related bus due to the response time of the EDG voltage regulator and govemor. On July 31,1998, the licensee submitted a proposed L TS change to incorporate the generic changes delineated in TS Task Force Traveler-
! 163 into the improved TSs. These generic changes supported the basis in the licensee's operability determination. Approval of the TS amendment is expected by October 15,1998.
l E8.6 (Closed) Inspection Follow-uo item 50-461/97999-03: Division ill EDG inoperable when

b Procedure 9080.02, " Diesel Generator 1C Operability," was inadequate in that the licensee inappropriately considered the Division ill EDG operable when inserting a 3 percent change in speed droop to allow paralleling the EDG to the grid during surveillance testing (see inspection Report 50-461/96011). The inspectors determined that the licensee's practice of setting the speed droop to 3 percent during testing resulted in the high pressure core spray pump being unable to deliver 5010 gpm of flow
'
to the reactor vessel at a differential pressure of 363 psid as required by TS SR 3.5. The SET identified that the design of the Division 111 EDG was not in accordance with Regulatory Guide 1.108, Revision 1, " Periodic Testing of Diesel Generator Units Used as Onsite Electric Power Systems at Nuclear Power Plants," and Regulatory Guide 1.9,
" Selection, Design, and Qualification of Diesel Generator Ucits Used as Standby i
Electric Power Systems at. Nuclear Pov'er Plants." The SET stated that per the regulatory guides the EDGs are to be designed tvith the ability to automatically transfer from the droop mode of operation to the isochronous mode of op9 ration in responsesto a LOOP /LOCA signal during testing and that this ability be tested. However, because the Division lil EDG was designed with a mechanical govemor instead of an electronic govemor, the EDG was unable to transfer between the droop and the isochronous modes of operation in response to a LOOP /LOCA signal during testing without operator i
action.
l During a subsequent review of this issue in June 1998, the inspectors identified that TS SR 3.8.1.17 required the licensee to verify every 18 months that each EDG would retum to ready-to-load operation (isochronous mode) and that the emergency buses would automatically be supplied by offsite power if an actual or simulated ECCS
.
initiation signal was received while the EDG was operating in the test (droop) mode and j connected to its safety-related bus. The inspectors questioned a shift manager to
- determine how the licensee was meeting this TS SR for the Division lli EDG. The shift i manager told the inspectors that the licensee had not recognized that the ability of the !
! Division ill EDG to automatically transfer from the droop mode to the isochronous mode l l during testing was required to be demonsaated per TS SR 3.8.1.17. The shift manager initiated CR 1-98-06-324 to document the inspectors' conce Technical Specification 3.8.1, "AC Sources-Operating," requires that three EDGs be '
,
operable while in Modes 1,2, and 3. Technical Specification SR 3.0.1 states that
! surveillance requirements shall be met during applicable modes for each individual LCO unless otherwise stated. The failure to meet a surveillance, shall be a failure to meet the LCO. Technical Specification SR 3.8.1.17 requires that the licensee verify every 18 months that, with an EDG operating in the test mode and connected to its l
bus, an actual or simulated emergency core cooling system initiation signal overrides l - the test mode by retuming the EDG to ready-to-load operation and automatically i energizing the emergency loads from offsite power. The failure to demonstrate compliance with TS SR 3.8.1.17 for the Division til EDG was considered a violatio This violation is of concem to the NRC since it resulted in the HPCS pump being unable to provide the flow required by TS or the core reflood accident analysis had an emergency core cooling system initiation signal been received during testing. However,
,
because the violation was based upon activities prior to the events leading to the
- current extended plant shutdown, the' NRC is exercising discretion in accordance with

Section Vll.B.2 of the Enforcement Policy and refraining from issuing a citation for this Severity Level IV violation (NCV 50-461/98014-01).
( The licensee determined that the reliance on manual action to compensate for the i inability of the Division 111 EDG to automatically transfer from the droop to the isochronous mode of operation in response to a LOOP /LOCA signal during testing constituted an unreviewed safety question. To resolve this concem, the licensee planned to submit an unreviewed safety question TS Bases change, which requires Commission approval prior to restart, to further describe the actual operation of the Division lli EDG during testing. If the Commission disapproves the licensee's TS Bases change, the licensee will be required to bring the Division til EDG into compliance with design requirements prior to declaring the Division lli EDG operable for Modes 1,2, and IV.

The inspectors noted that between July 1997 and July 1998, ten failures of the pager system occurred. Six failures would have required manual activation of the autodialer system if the Emergency Response Organization (ERO) had been activated. Once i manually activated, the system should have been able to process ERO responses in an automatic mode of operatio The remaining four failures involved programing issues, a loss of power, and a satellite failure such that the autodialer system could not have been manually activated eithe The failures would have required calling each person on the ERO individually. Given the four failures within a 1 year period, the inspectors questioned the licensee to determine if the capability to make the necessary telephone calls to ERO members had

P1.2 Performance of Accountability Exercise I Inspection Scope (71750)
The inspectors observed the licensee's accountability exercise performed on July 20,1998, i l Observations and Findinas !
Security personnel initiated actions to obtain a list of unaccounted for individuals 26 minutes after the initiation of the accountability exercise. After excluding individuals
'
on the exemption list, only four out of approximately 600 personnel were unaccounted for. Within 2 minutes, security personnel determined that three individuals were within the control room envelope and that the fourth individual had been inadvertently excluded from the exemption lis Following the drill, the licensee determined that the three individuals in the control room envelope were initially unacm.ited for due to their taking a break outside of the 800 foot elevation of the control building. After 3 weeks had elapsed, the inspectors questioned emergency planning personnel to determine if the individuals were considered essential and why they believed that taking a break instead of reporting to an assembly area was acceptable. Emergency preparedness personnelinformed the inspectors that they had the same questions following the exercise, and that the item was placed in a tracking system for revie Emergency preparedness personnel subsequently determined that the three individuals were considered essential and that they should have remained in the operations support center for the duration of the accountability exercise.
