EXECUTIVE SUMMARY
Beaver Valley Power Station, Units 1 & 2 l
NRC Inspection Report 50-334/98-01 & 50-412/98-01 i
This integrated inspection included aspects of licensee operations, engineering,
maintenance, and plant support. The report covers a 6-week period of resident inspection.
in addition, it includes the results of announced inspections by regional inspectors in the
areas of health physics and technical specifications, and an in-office review of an
unresolved item in the area of health physics.
Ooerations
- Good operator attention to reactor vessel level and supporting parameters during j
depressurization of the reactor coolant system (RCS) resulted in quick identification
and appropriate venting of a nitrogen gas bubble in the reactor vessel. (Section
01.2)
!
- Poor procedure quality and failure of operators to identify the procedural
deficiencies resulted in an unexpected feedwater isolation valve closure while
feeding the steam generators to wet layup conditions. (Section 04.1)
- Following the Unit 1 forced shutdown in January 1998, senior management
acknowledged the broad scope and significance of technical specification (TS)
surveillance testing problems. Both the NRC inspectors and a multi-faceted self-
assessment independently determined that long standing problems including poor ;
TS quality, a non-conservative philosophy regarding TS interpretation, and broad l
knowledge deficiencies regarding TS were the primary causal factors. Combined, l
these deficiencies have necessitated a significant amount of reactive work to
correct problems at the station. Management struggled to define the scope, detail, j
and implementation schedule for corrective actions. Senior management stated
their intent to complete appropriate corrective actions prior to restart of either unit.
(Section 08.1)
Maintenance j
- Implementation of the preventive maintenance (PM) program was adequate. The
'
number of delinquent PM tasks has been significantly reduced over the past ten
months. PMs were being performed as required, and PM deferrals were adequately
justified. (Section M1.2)
- Routine maintenance and surveillance testing was generally performed safely and in
accordance with procedures. System engineering and supervisor oversight was
good. Foreign material exclusion controls were properly instituted and followed.
The decision to repair all three Unit 2 PORVs to eliminate minor leakage prior to unit
restart demonstrated appropriate regard to maintaining plant material condition.
However, the 18 month overhaul of the Unit 2 2-2 emergency diesel generator
(EDG) was ineffectively planned. Conflicts with the clearance, multiple conflicting
il
.
.
.
tasks working cencurrently, and other scheduling problems resulted in extended
outage time for the EDG and additional risk of injury for workers. In addition, failure
to plan the post maintenance testing prior to beginning PORVs repairs delayed the
system restoration. (Section M1.3, M1.4, M1.5, and M1.6)
e Plant material condition and housekeeping were adequate. Control of transient
equipment was good. Most equipment deficiencies were identified by Material
Deficiency Tags; however, the inspectors noted an error rate in tag control of about
1/3, based on a random sample of 64 tags in the field. The high error rate had the
potential to mask equipment deficiencies or adverse trends. The corrective and
general maintenance backlog was properly prioritized. Minor maintenance was
properly categorized. Maintenance backlogs on individual systems were typically
low, though some outliers including the Unit 1 river water system and the fire
protection and heat tracing systems at both units, were noted. Systems were
properly monitored in accordance with the Maintenance Rule. (Section M2.1)
e The Maintenance organization was adequately staffed to support the plant.
However, maintenance planning and scheduling processes were not mature and
implementation of an action plan to improve work management had begun. The
inability to plan and work maintenance activities according to schedule contributed
to the need for additional resources, increased operator burden, and increased
equipment out-of-service time. Deficiencies in work package quality were not
effectively addressed. Fix-It-Now (FIN) team work was properly categorized and the
FIN program was effective in meeting its goals. The poor planning and control of
operational post maintenance testing (PMT) created an unnecessary operational
burden on the control room staff, as well as the potential to restore equipment to
service with inadequate PMT. (Section M6)
e The TS surveillance review team conducted a thorough and detailed review of the
TS surveillance requirements and associated surveillance procedures to ensure that
surveillance requircments were satisfied. Licensee actions to identify and resolve
problems were comprehensive and technically correct. The full TS surveillance
review tecm project was not implemented in a timely manner. Untimely
implementation and a larger than anticipated problem resulted in the licensee
requesting a commitment date extension from the NRC. Independent evaluation of
the surveillance review team's activities did not identify any discrepancies in their
program or its implementation. (Section M8.1)
Enaineerina
e The licensee recognized a TS deficiency regarding degraded voltage relay setpoints
in 1993 and administrative!y controlled the setpoints through revisions to the
maintenance surveillance procedures. The procedure revisions were inadequate and
a TS amendment request to change the relay setpoints had not been submitted.
The failure to adequately address a known TS deficiency in a timely manner was a
Violation. Two other examples of failures to address known TS deficiencies in a
timely manner contributed to LERs in the last year. (Section E1.1)

e The TS surveillance review team identified that the Unit 2 emergency diesel
generator ground switch was not tested as required by TS. This was attributed to
inadequate implementation of TS requirements into surveillance procedures, j
(Section E1.2) !
e Engineers failed to fully evaluate all potential failure modes prior to installation of a
modification to the Unit 2 emergency diesel generator (EDG) ground overcurrent trip
isolation feature which was an example of inadequate design control and a
violation. Specifically, the failure mode analysis for this design change was too
narrowly focused in that failures of the quality assurance category 2 ground switch 1
and resistor were not fully evaluated. The f ailure mode analysis also did not identify ;
or evaluate an additional failure mode which had the potential to damage the EDG '
during surveillance testing if a fault occurred on the 4 kV line. (Section E1.2)
Plant Suooort
e The programs for internal and external dosimetry and respiratory protection were i
effectively implemented. Control of radiological work, especially in the pressurizer l
cubicle at Unit 2, was also effective. (Section R1)

Report Details
Summarv of Plant Stetus
Unit 1 remained in Mode 5 (cold shutdown) in a forced outage throughout the inspection
period. The unit remained shut down to resolve several Technical Specification .
Surveillance Requirement (TSSR) compliance issues. One major issue required modification
to the nitrogen supply subsystem for the pressurizer power operated relief valves (PORVs)
and an exigent Technical Specification amendment to allow PORV testing within TS
requirements (applicable to both units).
Unit 2 remained in Mode 5 (cold shutdown) in a forced outage throughout the inspection
period. The unit remained shut down to resolve several TSSR compliance issues.
Additional work included completion of repairs to station battery 2-1 and repairs to all three
pressurizer PORVs due to leaks.
1. Operations
01 Conduct of Operations
01.1 General Comments (71707)
Using inspection Procedure 71707, the inspectors conducted frequent reviews of
ongoing plant operations. Inspectors noted a good focus on shutdown safety over
the period. The shutdown safety function / equipment status sheet was reviewed at
the beginning of the daily supervisors' meetings and at each shift turnover briefing.
Changes in safety function status (reactor coolant system (RCS) core cooling,
reactivity control, electrical power, spent fuel pool cooling, and boration inventory)
were discussed and limitations due to ongoing or planned work and train priority
were highlighted. Operators displayed a good questioning attitude when evaluating
the impact of clearances and work on shutdown safety and TS compliance.

On February 24, Unit 2 operators noted a slight decrease in the reactor vessel level l
indicating system and an increase in volume control tank and pressurizer levels i
during depressurization of the RCS. The operators promptly identified the
conditions, and the senior reactor operators evaluated appropriate corrective )
actions. The cause of the level changes was determined to be nitrogen gas coming I
out of solution and creating a gas bubble in the reactor vessel. Operations ;

criteria. The reactor vessel was vented and parameters returned to expected
values. The inspectors noted continued operator awareness of the level parameters ;
and appropriate logging of the parameters during subsequent reactor head venting ,
which occurred approximately every two days.
l
c. Conclusions
Good operator attention to reactor vessel level and supporting parameters during
depresaurization of the RCS resulted in quick identification and appropriate venting ,
of a nitropn gas bubble in the reactor vessel. I

I
'
a. Insoection Scope (71707)
The inspectors reviewed the operation staff's response to an unexpected Unit 2
feedwater isolation. The inspectors interviewed the operators and shift technical
advisors, and reviewed operator logs. Also, procedure 20M 24.4.1, " Feeding Steam
Generators at Low Pressure and Little or no Steam Flow," Rev.12, was reviewed.
b. Observations and Findinas j
On March 16, while attempting to raise the steam generator (SG) levels to wet
layup condition, the feedwater isolation valves (FWlVs) unexpectedly closed due to
high SG level. The operators believed that the procedure (20M-24.4.1) blocked the 1
feedwater isolation signal by deenergizing the FWlV 480VAC power supplies. !
However, the 125 VDC power supply to the solenoid operated valves that perform !
the auto-closure function for the FWlVs, was not deenergized. The operators reset j
the feedwater isolation signal, opened the FWlVs, and completed the wet layup of !
the steam generators.
After the isolation, operators identified the following procedural weaknesses: 1) the
procedure failed to identify the 125 VDC power supply; 2) the procedure did not <
return the 480VAC power supply to normal system alignment, but the procedure
had previously been reviewed to verify that it restored equipment to normal ]
alignment; and 3) the Operating Manual (OM) procedures did not receive validation i
prior to approval. The unexpected closure and procedural weaknesses were l
captured in Condition Report 980506 and corrective actions include upgrading the
procedure. The inspectors determined that the procedural weaknesses combined
with the failure of operators to previously identify and correct the weaknesses
directly led to the FWlV closure. The inspectors reviewed the reportability
determination and concluded that operators appropriately determined that the event
was not reportable. The procedure recognized the potential for actuating the FWlV
signal; however, it did not adequately establish conditions to prevent FWlV closure.
l
,
.

i
The failure to establish an adequate procedure to raise steam generator level to wet l
layup conditions without causing an unnecessary feedwater isolation was a
'
violation of TS 6.8.1.a. This non-repetitive, licensee-identified and corrected
violation is being treated as a Non-Cited Violation, consistent with Section Vll.B.1 I
of the NRC Enforcement Policy (NCV 50-412/98-01-01).
c. Conclusions
!
Poor procedure quality and failure of operators to identify the procedural I
deficiencies resulted in an unexpected feedwater isolation valve closure while
feeding the steam generators to wet layup conditions.

Proaram Deficiencies
a. insoection Scone (71707,92901,92902,92903) i
.a
The January 31,1998, Unit 1 forced shutdown highlighted the continued presence i
of TS surveillance testing program deficiencies. During interviews with NRC l
inspectors, senior management stated their intent to determine the scope of the
problem and implement appropriate corrective actions prior to restarting either unit.
The inspectors reviewed license basis documents, reviewed licensee causal ;
assessments, and interviewed personnel to evaluate licensee actions to assure TS '
requirements were properly implemented.
i
'
b. Observations and Findinas
!'
The Plant Manager met with the inspectors in early February to discuss what -
actions the licensee planned to implement prior to unit restart, to provide assurance j
that TS surveillance requirements were properly implemented. Based on the cause !
of the recent Unit 1 shutdown, station management recognized that methods used )
when performing some of the earlier test program reviews may have been
incomplete. Prior to late 1997, the station-wide philosophy regarding compliance ;
with TS requirements had often permitted too much leeway regarding interpretation
of TSs. The station manager identified three specific areas for reevaluation; (1) Unit
1 NRC Generic Letter (GL) 96-01 testing, (2) Units 1&2 Emergency Core Cooling i
System TS required testing, and (3) Units 1&2 Electrical Distribution System TS l
- required testing. Additional reviews would be considered during evaluation of
several condition reports recently submitted regarding TS surveillance testing l
issues.
The inspectors noted that the large number of TS surveillance testing issues
identified during the past two months and the difficulty the licensee experienced in
evaluating the issue which resulted in the Unit 1 forced shutdown, indicated TS
knowledge deficiencies existed throughout the licensee organization. Several
additional factors, including poorly written TSs and implementing procedures, were
.
.
4
evident. The inspectors questioned whether the licensee's planned actions were
sufficient to provide assurance that the units were operated and tested as required
by the TSs. The Plant Manager stated that additional actions would be considered
if warranted. The following week a more detailed TS Surveillance Testing
' Compliance Oversight (TSSTCO) project was established.
The inspectors met with the TSSTCO project manager and reviewed project status.
The project centered on five self assessments of previously completed or ongoing
activities including the following:
1
e Unit 2 electrical distribution system safety system functional evaluation
(SSFE) completed in 1997, ~:
'
o all licensee event reports (LERs) and NRC violations (NOVs) issued from mid-
1996 through present,
o TS surveillance testing review team findings (see Section M8.1),
e Updated Final Safety Analysis Report (UFSAR) validation project, and
o NRC GL 96-01 test program evaluations.
The self assessments were performed using a more stringent philosophy regarding
TS compliance. Related condition reports issued over the past two months were
also reviewed in the aggregate. Training was developed and conducted for all
licensed operators based on the lessons learned from the self assessments.
Independent industry consultants also performed a broad oversight review of the
collective significance of the TS surveillance testing issues. Based on interviews
and independent evaluation of selected issues from the licensee self assessments,
the inspectors determined that the licensee assessment of the TS surveillance
program deficiencies was detailed, causal assessment was adequate and initial
corrective actions were properly implemented.
The TSSTCO project manager effectively presented a project status update to the
Nuclear Safety Review Board in early March, noting that several of the self
assessments and corrective actions were stillin progress. Self assessments and
corrective actions continued through the end of the inspection period. The
inspectors independently determined that long-standing problems, including poor TS
quality, a non-conservative philosophy regarding TS interpretation, and broad
knowledge deficiencies regarding TSs were primary causal factors behind the
current TS surveillance program issues. Combined, these deficiencies resulted in a
significant amount of reactive work to correct problems at the station. A large
procedure change backlog was a contributing factor. Licensee evaluation of the
issue began to develop similar detailed findings as the report period ended.
Numerous corrective actions were initiated to provide assurance that the station
would be operated in accordance with TS requirements. The majority of
approximately 80 TS interpretations were canceled and the remainder were
withdrawn from the control room for further evaluation. The licensee also
committed to upgrade both units to the improved standard TS following completion
of the UFSAR validation project in 1999. A training plan was under development to
upgrade station-wide knowledge of TS. The inspectors noted that licensca
.
.
5
management had difficulty maintaining integrated oversight for the numerous
corrective actions. Management acknowledged that several of the corrective action
elements required further development and that an overall implementation schedule
had not yet been developed. Senior management reaffirmed the their intent to
verify the station was in compliance with TSs and address the root causes to
preclude recurrence prior to unit restart.
c. Conclusions
Following the Unit 1 forced shutdown in January 1998, senior management
acknowledged the broad scope and significance of TS surveillance testing problems.
Both the NRC inspectors and a multi-faceted licensee self assessment independently
determined that long-standing problems including poor TS quality, a non-
conservative philosophy regarding TS interpretation, and broad knowledge
deficiencies regarding TSs were the primary causal factors. Combined, these
deficiencies necessitated a significant amount of reactive work to correct problems
at the station. Management struggled to define the scope, detail, and
implementation schedule for corrective actions. Senior management stated their
intent to complete appropriate corrective actions prior to restart of either unit.
08.2 Offsite Review Committee Meetinas (71707)
The inspectors attended portions of the Maintenance and Engineering _
Subcommittee, Operating Experience Subcommittee, and Offsite Review Committee
meetings on March 3 and 4. Committee members expressed concern with the
number of issues being identified at the site and the potential impact on plant
restart. Through discussion with DLC management, inspectors verified that the
concern was with identifying all of the issues that were reasonable to find and was
_
not mistaken as a recommendation to restart the units hastily. The President,
Generation Group, reiterated to the committee and to DLC management that safety
was paramount and that the units would not be restarted until there was adequate
assurance that they would be operated in compliance with license requirements.
The inspectors assessed that his statements were appropriate to ensure that a
mixed message was not being given to the site,
11. Maintenance
M1 Conduct of Maintenance
M1.1 General Comments (62707)
The inspectors reviewed several maintenance program elements to verify that
activities were properly planned and scheduied, conducted in a safe and controlled
manner, and conducted in accordance with approved procedures. The backlog of
both corrective maintenance and preventive maintenance activities was reviewed on
.
.

6
a sampling basis to verify that all identified plant equipment deficiencies were
properly evaluated and prioritized. Interviews were conducted with personnel at all
levels of the organization, and observations were made of several ongoing
maintenance activities.
M1.2 Preventive Maintenance Proaram
a. Insoection Scone (62707)
- The inspectors reviewed the adequacy of the preventive maintenance (PM) program,
including the backlog, PM deferrais, and the status of the PM Optimization Program.
b. Observations and Findinas
DLC added two PM Coordinators to the Work Management organization in August
1997. The inspectors reviewed the governing instruction for the PM program,
NPDAP 8.31, "PM Program," Rev. 2 and discussed program implementation with a
PM Coordinator. DLC has not yet completed baselining the PM schedule, but it
appeared that PM tasks were properly scheduled and controlled. The coordinators
were providing PM tasks to the schedulers about three months ahead of the 12-
week schedule process. PM optimization was in progress at the rate of about three
site systems per month by the system engineering staff. Seven systems were
complete, and PM rescheduling / modification justification forms had been provided
to the coordinators. DLC intended to complete review of all critical systems by the
end of 1998, and complete the program by April 1,1999.
The inspectors noted that delinquent PM tasks (PMs beyond their established
duration by more that the 25% grace period) had been reduced from 53 in May
1997 to zero in November 1997. There had been one delinquent PM since then,
which was documented on Condition Report 980320. Deferred PMs were also
trending less than 3 per week. The inspectors reviewed 10 PM deferrals and
assessed that they were adequately justified. The inspectors also reviewed the PM
feedback forms submitted by craftsmen after completion of the PM tasks. Almost
all of the feedback was positive; few substantive comments were noted,
c. Conclusions
Licensee implementation of the PM program was adequate. The number of
delinquent PM tasks has been significantly reduced over the past ten months. PMs
were performed as required, and PM deferrals were adequately justified.
M1.3 Routine Maintenance Observations (62707)

PORV post maintenance testing (further discussed in Section M1.6), and that would
result in extension of the Unit 2 shutdown, licensee management expanded the
scope of the forced outage. Outage management scheduled additional work
activities, including items scheduled for the next Unit 2 refueling outage, such as
the 18 month overhaul of the 2-2 EDG.

During observations of the work activities, the inspectors noted multiple ongoing
work activities that appeared to conflict with each other. The inspectors observed -
worker safety issues that resulted from the multiple tasks including fuel oil dripping
down on workers and reliance on one-way verbal communication during EDG shaft
rotations. The inspectors observed that good foreign material exclusion (FME)
controls were implemented.
After several days, the inspector noted that the EDG work activities were behind
schedule and questioned work planning and outage management concerning the
planning for the EDG work. Initial delays were due to limited knowledge level of the
construction workers in building the scaffolding for the EDG work. The clearance
established for the EDG work resulted in an inability to perform an Instrumentation
and Controls (l&C) maintenance surveillance due to removal of a DC power source.
This l&C surveillance is normally scheduled during the 18 month overhaul. The
maintenance supervisor had already noted the problems with the scaffolding and l
clearance, and immediate corrective actions had been taken. Further discussion
with outage management revealed that a detailed schedule for the EDG outage had
not been prepared. Normally, major work activities conducted at the site have a
detailed schedule. After discussions, the outage manager agreed that a more
detailed schedule would be appropriate and one was constructed.
The inspectors concluded that the lack of detailed planning and preparation for the
18 month overhaul of the 2-2 EDG resulted in additional outage time and additional
risk of injury for workers. The original schedule for the outage was approximately
10 days and the actual outage time was 14 days.
c. Conclusions
The 18 month overhaul of the Unit 2 2-2 EDG was ineffectively planned. Conflicts
with the clearance, multiple conflicting tasks working concurrently, and other
scheduling problems resulted in extended outage time for the EDG and an additional
risk of injury for workers. Good FME controls were instituted and followed.

b. Observations and Findinas
The licensee decided to repair all three Unit 2 Pressurizer PORVs after observing
increased leakage through the PORVs in service for low temperature overpressure
protection. Based on temperature measurements and observations during the past >
refueling cycle, the system engineer observed minor leakage through the PORVs (a
maximum of 80 gallons per day). The inspectors noted thorough tracking and
trending of the PORV conditions by the system engineer.
' The repair consisted of replacement of the pilot valves with improved seating
material and repair / replacement of the PORVs. The inspectors noted good initial
planning with multi-discipline input and in-depth questioning. However, the post
maintenance testing (PMT) was not planned until midway through the actual work.
The inspectors observed good vendor and supervisor involvement, and FME controls
during the repair activities. The inspectors identified and informed the work crew of
some minor deficiencies in their radiological work practices. The inspectors'
observations were promptly addressed. The resolution of material discrepancies
noted in the repair were successfully handled through vendor and onsite
engineering. ,
The PMT was planned under a temporary procedure, 2 TOP 98-02. The Onsite
Safety Committee determined that the PMT could not be performed due to conflicts
with Technical Specification requirements. TS 3.4.9.3 requires that the
overpressure protection system shall be operable with either two PORVs available or
the RCS depressurized and an RCS vent established. The PMT required
pressurization of the RCS and stroking of the valve. This was in direct conflict with
the TS requirements. The licensee determined that licensing action would be
required. During reviews, operators noted other instances where the PMT could be
in direct conflict with TS requirements. On March 16, the licensee submitted an
exigent TS amendment request to allow PMT under administrative controls to bring
equipment back to service,
c. Conclusions
The decision to repair all three Unit 2 PORVs to eliminate minor leakage prior to unit
restart demonstrated appropriate regard to maintaining plant material condition. The
PORV removal and inspection activities were characterized by good initial planning,
vendor involvement, and supervisory oversight. However, post maintenance testing
was not planned until after the work began and conflicted with Technical
Specifications. Failure to plan the PMT prior to beginning repairs delayed the
system restoration.

l M2 - Maintenance and Material Condition of Facilities and Equipment ;
M2,1 Housekeepina and Material Deficiency Tao issues
a. Insoection Scope (62707)
Inspectors made a number of plant tours and conducted several partial walkdowns
of systems to assess the material condition of the plant. This included a review of
identified maintenance deficiencies to verify that the condition of plant equipment
was acceptable to support safe operation. Inspectors also verified that identified
deficiencies were being prioritized and corrected commensurate with their safety
significance.
b. Observations and Findinas
During plant tours and walkdowns of systems, the inspectors noted some minor
deficiencies, such as valve packing leaks, oil leaks, loose or unattached lagging, and
inoperative lighting. Most deficiencies were captured on deficiency tags, but some
minor deficiencies were not marked by deficiency tags or captured in the
. maintenance database against the component. For example, packing leaks were
noted on valves TV-1CCR-121-1,TV-1CCR-137, and a flange downstream of
2CHS-578 (with drip bag installed); an oil leak was noted on CH-P-1B motor; small
l oil leaks were noted on the 1VS-AC-9 fan motor, GW-C-1B, and MOV-1HY-101B; a
! valve label had fallen off 1PC-118; area lights were burnt out behind 1VS-AC-8,
over BR-P-2A, and in the Unit 1 west cable vault lower passageway; and smoke
detectors in the Unit 1 west and east cable vaults and the control room were
marked " bad," with no accompanying explanation. These discrepancies were
referred to the nuclear shift supervisor for evaluation. Overall, plant housekeeping
was considered to be adequate.
.
Control of transient equipment such as carts, scaffolds, and test equipment was
!
good. One unrestrained ladder that was not in use was noted outside the boron
recovery evaporator cubicle. This was referred to the radiological controls shift
supervisor for resolution.
The management expectation was that Material Deficiency Tags would be used to
identify equipment deficiencies, with the exceptions of containment or areas where
radiological or personnel safety concerns took precedence. Most equipment
deficiencies were identified by Material Deficiency Tags; however, some
discrepancies were noted. The inspectors selected 64 tags during plant tours to j
verify their tracking status. The tags originated from 1995 to date. Forty-two tags j
were in the work control process and work was in progress (about 66%). The work '
for 11 tags was complete, but the tags were still hanging in the field (about 17%). l
Eleven tags were not entered in the work control system (about 17%). These
L
..
.
11
indicated an error rate of about 1/3 in the deficiency tag system. The high error
rate had the potential to mask equipment deficiencies or adverse trends. The
inspectors discussed the issue with Maintenance management. The licensee
generated Condition Reports 980474 and 980475 to document further evaluation
under the corrective action program.
The non-outage corrective and general maintenance backlog was 1011 items, as of
March 8. The trend had been downward from 1221 items in November to 929 in
January, but had climbed slowly since the beginning of the dual unit forced
j outages. Management anticipated reversing the trend when the units were returned
l-
'-
to service, but planned to review the data more closely in the summer to decide
whether additional focused effort would be necessary to meet a year-end backlog
goal of 800 items. The inspectors reviewed the corrective and general maintenance
backlog and assessed that it was properly prioritized. The inspectors reviewed the
backlog of work for selected safety-related systems that were important to
- mitigating core damage in accordance with the probabilistic risk assessment. For
Unit 1, the river water system with 25 maintenance work requests (MWRs), the
steam generator feedwater system (including auxiliary feedwater) with 13 MWRs,
and the 4kV station service system with 12, had the highest backlogs among the
top risk-important systems. For Unit 2, the service water system with 13 MWRs
j had the highest backlog among risk-important systems. The inspectors reviewed
the System Engineering System Status Report,4th Quarter 1997, and assessed that
I systems were being properly monitored in accordance with the Maintenance Rule.
. In general, backlogs of priorities-3 and 4 MWRs for non-risk-important individual
! systems were low (typically less than twelve). Some outliers at Unit 1 were water
treating systems with 44 MWRs and boron recovery and primary makeup systems
- with 28. The inspectors also noted large backlogs in the fire protection system (8
l priority-3 and 72 priority-4 MWRs) and miscellaneous safety-related instrumentation
l system (3 priority-3 and 59 priority-4 MWRs), the majority of which were heat
tracing system deficiencies. At Unit 2, outliers included the condensate polishing )
l system with 22 MWRs and the auxiliary boiler system with 18. The Unit 2 fire
- protection system and electric heat tracing system also had large backlogs (31 and
'
16 MWRs, respectively).
!
l In addition, the inspectors reviewed the non-outage minor maintenance backlog.
l
The minor maintenance backlog was 494 items (as of March 8) and had trended at '
l about 500 since November. The backlog appeared to be properly categorized in l
j' accordance with Nuclear Power Division Administrative Procedure (NPDAP) 7.15, !
" Initiation of a Work Request."
c. Conclusions
Plant material condition and housekeeping were adequate. Control of transient
equipment was good. Most equipment deficiencies were identified Sy Material
Deficiency Tags; however, the inspectors noted an error rate in tag control of about 4
1/3, based on a random sample of 64 tags in the field. The high error rate had the ,
potential to mask equipment deficiencies or adverse trends. The licensee
e
o
!
12
documented the observation in the corrective action system for additional
- evaluation. The corrective and general maintenance backlog was properly
!
prioritized. Minor maintenance appeared to be properly categorized. Maintenance
backlogs on individual systems were typically low, though some outliers were
noted, for example, the Unit 1 river water system and the fire protection and heat
tracing systems at both units. Systems were properly monitored in accordance with
the Maintenance Rule.
M6 Maintenance Organization and Administration
a. Insoection Scope (62707)
,
The inspectors assessed the ability of the Maintenance organization to support the
plant. The organization reported to the General Manager, Maintenance Programs -<
Unit (MPU), who reported to the Plant Manager. The MPU was divided into the
Mechanical, Electrical, l&C (Instrument and Controls), Fix-It-Now (fin) Team,
Maintenance Support (such as procedures, corrective action program, self-
assessment, and performance indicators), and Work Management Sections
(planning and on-line scheduling).
b. Observations and Findinas
The maintenance organization was adequately staffed to support the plant. l
Maintenance staff were working on average about 15 hours1.736111e-4 days <br />0.00417 hours <br />2.480159e-5 weeks <br />5.7075e-6 months <br /> of overtime per week.
There was not a dependence on excessive overtime to accomplish work nor on
contractor support, except in the Work Management Section, where 18 of 45
positions were filled by contractor personnel. The Work Management Section has
been evolving since June 1997, when the licensee implemented a Maintenance
Improvement Plan to improve planning, scheduling, and work control processes;
otherwise, the organization has been relatively stable.
The inspectors noted that stabilizing the 12-week work management process,
.
enforcing schedule discipline, and reducing the corrective maintenance backlog
were among the top concerns of the Maintenance organization at alllevels. Some
I
other concerns mentioned were inaccuracies in the Material Equipment List (MEL),
parts support, quality of work packages, and a weak Maintenance database j
management software program. The inspectors noted that most of the concerns l
were related. !
Inaccuracies in the MEL were a frustration for planners, particularly the contractor
staff who typically had a lot of experience in planning, but did not have as much l
specific experience at Beaver Valley as the DLC employees. Lack of trust in the i
MEL forced the planners to spend more time in the field verifying parts information.
Nevertheless, craftsmen frequently mentioned incorrect parts, insufficient quantity,
or incorrect revision as deficiencies in the work packages.
l
t
.
.
13
The inspectors noted that a contributing factor in parts problems was the short lead
time provided to the Nuclear Procurement Department (NPD). According to NPDAP
7.12, "Non-Outage Planning, Scheduling, and Risk Assessment," Hev.4, parts
should be identified and ordered in weeks 9 through 7 before the work execution
week; however, NPD performance indicators for 1997 showed about 45% of parts
'
were identified after week 7. The impact of emergent work and failure to control
work scope were also contributing factors. Maintenance management did not have
a current performance indicator to measure those variables, but one indicator from
1997 showed that the percentage of work scheduled at week 7 was typically less
than the goal of 60% of the activities worked during the execution week. The
Work Management Section was in the process of developing a performance
indicator to measure scope growth and control throughout the 12-week process.
This would also give an indication of the effect of emergent work on the scope.
Comments from the field and on daily schedule report feedback forms indicated a
high level of frustration with the accuracy of the schedule. The inspectors assessed
that the 12-week work management process was ineffective and had not yet
matured. The inability to plan and work maintenance activities according to
schedule contributed to the need for additional resources, increased operator
burden, and increased equipment out-of-service time.
in some cases, craftsmen contributed to poor work package quality by failing to
take advantage of feedback mechanisms. According to the On-Line Scheduling
Desktop Guide, work packages should be sent to work groups for pre-job walkdown
four weeks prior to the execution week and discrepancies should be resolved with
the planner prior to execution. A feedback form was provided in the work package
for field comments to the planner following the work to improve package quality. In
reality, walkdown quality and feedback varied considerably. Some craftsmen said
they had never walked down a package. Some were unsure of what kind of
feedback to provide. The l&C Maintenance Section provided a checklist to
technicians to fill out when doing walkdowns. The checklist provided some
expectations and consistency, but some felt it was too restrictive. Similar
comments were made about the post-work feedback form. Some technicians said
they had never filled one out. The inspectors reviewed several feedback forms and
noted a wide variety of response, from no comment to very detailed comments
regarding tools, parts, or refererace material required. Maintenance management
tracked work package quality by trending the feedback forms; 89% of the work
packages from August 1 to December 31 were rated excellent or good. In
December and January,85% were rated excellent or good, and in February 80%
were rated excellent or good. These high ratings did not match comments from the
field While some craftsmen noted that work package quality had improved over
the last year, most commented that much improvement was needed.
DLC used three work management databases. The automated work order (AWO)
system was used for MWRs, FIN work orders, and PMs. The Maintenance Planning
and Scheduling System (MPS) was used to maintain information on predictive
repetitive tasks, but it did not have true scheduling capability. The Primavera
system was used primarily for outage scheduling. The only integration of the three
systems was a manually requested download of data from the AWO, which was )
)
1
)
.
.
14
. manually manipulated and fed into Primavera. There was no automated feed of PM
data into Primavera. PM tasks were manually entered from information out of MPS.
Most planners and schedulers found the current software tools cumbersome and
~ labor intensive. improvements made in one work package or schedule could not be
easily copied onto the next task. Many looked forward to the proposed
implementation of the DEMMAND system later this year, but they were unsure of
how the DEMMAND system would interface with the existing systems.
! The licensee recognized many of the weaknesses in the work management process
early in 1997. QSU Maintenance Audit Report BV-C-97-04, dated June 27,1997,
concluded that site maintenance was not fully effective. MPU implemented a
,
Maintenance improvement Plan (MIP) in June 1997 to improve planning, scheduling,
I
and work control processes. The inspectors reviewed the MIP status report dated
February 12. Many action items had been extended more than once or were
overdue, such as defining facilities to support the Work Control Center function,
developing a schedule that reflects work at the crew level, developing perfo;mance
indicators relating to milestone adherence and work week implementation, rcrquiring
and tracking work package walkdowns, developing job descriptions and filling
planning positions, developing planning performance indicators, revising the MEL,
and developing a post-maintenance test matrix. Some MlP action items that were
successful were development of the FIN Team and establishment of a Work Control
Center, though the center was still evolving. The inspectors assessed that the daily
screening meeting for new work and the daily work week management meeting
were good initiatives developed over the past year. These were generally attended
by representatives from the maintenance disciplines, operations, SPED, NPD, health
.
'
physics, security, FIN, construction, outage management, and planning and
scheduling, as appropriate, and promoted consistency and communications in the
work management process.
In February, the licensee formed a multi-disciplined Work Management j
Implementation Team (WMIT) to expand the MIP effort sitewide. The goal of the j
team was to coordinate site resources and work activities through the work .i
management process to assure nuclear safety, equipment reliability, and economic !
efficiency. The licensee approved a comprehensive action plan developed by the
WMIT on March 13. The initial implementation milestone was targeted for April 6.
The inspectors reviewed the action plan and attended the meeting of the Work l
.
Performance Review Board that approved the action plan. The plan addressed ,
I
many of the weaknesses that the licensee identified in the work management !
process and recommended an aggressive schedule for action items. The WMIT i
action plan was a good initiative, but it was too early in the process to fully l
evaluate its effectiveness.
I
FIN Team
The inspectors reviewed the Fix-It-Now (FIN) program, which was previously
reviewed in NRC Inspection Report 50-334 and 412/97-04, Section M1.4. The FIN
Team backlog of corrective, general, and minor maintenance was 291 items, of
which 204 were minor maintenance activities (as of March 8). FIN backlog had
l
,.
\ .
15
,
fluctuated between about 250-300 since November. The FIN minor maintenance
! backlog was reduced from 680 in May 1997 to 280 at the end of the year. A FIN
I
Team priority in 1997 was control room deficiencies. Control room deficiencies
l were reduced from about 75 in May 1997 to 14 in February. FIN work appeared to
! be properly categorized in accordance with Maintenance Programs Unit
Administrative Procedure (MPUAP) 4.11, "Fix-It-Now Maintenance Program." The
FIN Team was conducting a relatively small amount of emergent work (Priority 2
and 3),4% at Unit 1 and 9% at Unit 2 for the year-to-date. Inspectors noted that
the WMIT goal was to have the FIN Team work 80% of emergent work in order to
" protect" the schedule, but how this would be accomplished was still under
discussion by Maintenance management. Overall, the FIN program was effective in
i meeting its goals.
Ooerational Post-Maintenance Testina
The inspectors noted 115 MWRs in the Unit 1 control room and 149 MWRs in the
Unit 2 control room that were complete and awaiting operational post-maintenance
testing (PMT). The MWRs were sorted in stacks by the physicallocation of the
equipment to be tested (such as turbine building, containment, or auxiliary building).
The inspectors reviewed 38 of the MWRs for the Unit 1 auxiliary
building / safeguards area, as well as a sample of MWRs from other Unit 1 and 2
areas. Some deficiencies were noted. Many of the MWRs awaiting operational
PMT were from work done during the extended refueling outage on Unit 1 and the
current forced outages on both units, but two were for work completed in 1996
(MWRs 051638 and 051256). The work leader signed MWR 044221 as complete
on 11/19/97, but the maintenance foreman did not signify review until 3/6/98. The
work leader signed MWR 061859 as complete on 4/12/S7, but the maintenance
foreman did not signify review until 11/15/97. The nuclear shift supervisor signed
MWR 060987 as unsatisfactory (PMT failed) on 7/26/97, but the MWR was still in
the control room.
Operational PMT requirements were determined and specified on very few of the
MWRs. PMT for many of the MWRs was delayed because of current plant
conditions; however, there was no tracking method to aid operators in determining I
when conditions would exist that would allow PMT for a particular MWR. As l
systems or components were returned to service, operators had to sift through the
stacks of MWRs to determine if any of the affected equipment was awaiting PMT
and then define the operational PMT to be performed. Operational PMT was not
consistently determined during the planning of the MWR. The inspectors reviewed
l the MWRs awaiting testing and did not identify any safety related or risk significant
MWRs which did not have an appropriate PMT specified. The inspectors assessed
that planning and control of operational PMT was poor, that it created an j
unnecessary operational burden on the control room staff, and could result in
l
restoration of equipment to service with inadequate PMT. Station management i
acknowledged this finding and stated that better controls over PMT identification
and tracking would be implemented. i
,
.
16
c. Conclusions
The Maintenance organization was adequately staffed to support the plant.
Maintenance planning and scheduling processes were not mature, and the licensee
has begun implementation of an action plan formed by a multi-disciplined team to
improve work management. The inability to plan and work maintenance activities
according to schedule contributed to the need for additional resources, increased
operator burden, and increased equipment out-of-service time. Tools to improve
work package quality, such as pre-job walkdowns and work package feedback j
forms were not consistently performed. . FIN work appeared to be properly 1
categorized and the FIN program was effective in meeting its goals. The poor
planning and control of operational PMT created an unnecessary operational burden
on the control room staff, as well as the potential to restore equipment to service
with inadequate PMT. !

The Technical Specification Surveillance Review (TSSR) team activities were a key.
element of licensee corrective actions discussed in Section 08.1. The inspectors
conducted the review to provide an independent assessment of the technical
adequacy and the level of detail of the licensee's corrective actions that were taken
to resolve surveillance program weaknesses and inadequacies identified by the NRC
escalated enforcement action in June 1997. The inspectors reviewed several
condition reports (CR) that were issued as a result of the review team's activities to
evaluate the completeness and quality of the corrective actions planned or !
implemented to resolve the CR. The inspectors also evaluated the review team's
charter, interviewed personnel on the review team and independently reviewed
three selected systems that had TS surveillance requirements to verify that the
review team had also reviewed each section in detail.
b. Observations and Findinas ,
!
TS Surveillance Review Team and Their Charter
in general, the team charter required the team to review each Technical
Specification's surveillance requirement, verify requirement appropriateness as
stated in the most recent.TS revision,' verify associated surveillance procedures
satisfy TS surveillance requirements, verify that the TS/ surveillance procsdure
matrix was correct, and verify scheduling satisfied required time intervals. The
charter was approved on December 23,1997. The review team's orpaalzation
consisted of a project coordinator and three contractor personnel who had held SRO
' licenses or were SRO-certified and one SRO licensed at Beaver Valley. The
contractor personnel began their review in early November 1997 and the Beaver .

,
.
17
Valley SRO began full time review activities in mid-December 1997. These
personnel were the central group conducting the major portion of the review. Other
personnel were used when needed to supplement certain technical or engineering
areas during the review. Identified problems were corrected through the established
site condition reporting (CR) system or the normal procedure revision process on an
expedited schedule. At the time of this inspection, the review team's activities had
resulted in 69 CRs relating to surveillance problems.
Based on interviews with review team members and an evaluation of several
problems identified by the review team, the inspectors determined that, for the
items reviewed, the team had conducted a detailed review of the TS surveillance
requirements. However, the full implementation of the TS surveillance review team
was not implemented in a timely manner, such that the licensee's January 30,
1998, commitment date would be met. The late implementation and a larger than
anticipated problem resulted in the licensee requesting a commitment date
extension from the NRC.
Condition Reoorts
The following condition reports (CR) were reviewed by the inspectors and were
resolved by the licensee, except as noted:
. CR No. Descriotion
- 980258 Westinghouse letter 2DLS-8028 requires that the charging
pump starts within 11 seconds of the initiation of an
emergency diesel generator (EDG) start. Unit 2 Updated Final
Safety Analysis Report (UFSAR) specified times (10 seconds
for EDG and 1 second for the charging pump) and TS 4.8.1.1.2.b.7 specified tolerance (plus or minus 10% of 1
second) would allow the 11 second (maximum value) start
value for the charging pump specified to be exceeded.
- 980169 TS surveillance requirements 4.7.3.1.b. and c., and 4.7.4.1.b
and c. had not been performed for all safety related equipment
associated with the Unit 1 river water (RW) and component
cooling water systems and Unit 2 service water (SW) and
component cooling, primary (CCP) systems. The surveillance
requirements involved valve lineup verification and cycling of
- 980321 Determine Unit 2 auxiliary feedwater (AFW) check valve full
stroke flow rate requirements. This CR also addressed flow
requirements for the Unit 1 high head safety injection (HHSI)
check valve flow rate requirements.
- 980305- Two problems reported in CR; 1) existing instrument channel

functional test following calibration, and 2) when functional
test was required it did not meet requirements of IEEE 338
l (1977) as discussed in UFSAR, Section 1.8. This CR was in
l the process of being resolved.
- 980227 Beaver Valley calibrates the reactor coolant system wide range
and narrow range resistance temperature detectors (RTD)
using the " cross-calibration" method. The TS states that a
calibration verifies that the channel responds within the
necessary range and accuracy to known values of the
parameter that the channel monitors. This CR was in the
process of being resolved.
For the CRs that had been resolved by the licensee, the inspectors reviewed the
licensee's resolution and corrective actions and found them acceptable as discussed
below.
CR 980258 concerned the UFSAR one second start time specified for the charging
pump when loaded onto the EDG (step 2 of the load sequencer). The TS allow a
plus or minus 10% acceptance time for the one second which means that the
charging pump can start up to 1.1 seconds after the 10 second, or less, EDG start
time. The Westinghouse analysis and letter 2DLS-8028 assumes a maximum of 1
second. With the 10% allowable acceptance criteria the maximum allowable time
could exceed the 11 seconds (10 seconds plus 1.0 second) allowed by analysis.
The licensee's immediate corrective action verified that the actual total elapsed time
was acceptable in the last surveillance test. The inspectors obtained copies of the
last surveillances and verified that times were acceptable. The licensee initiated a
UFSAR revision to change the allowed start time to O_.9 seconds which will ensure
,
that the overall start time is less than 11 seconds. A procedure change was
l initiated and a 10 CFR 50.59 evaluation was also performed.
CR 980321 resulted when new minimum operating point (MOP) curves were
calculated by the licensee's engineering department. This is a problem if the MOP
is increased and the check valve has not been tested to ensure that it will pass the
higher flow rate requirements. Subsequent review by the licensee determined that
full flow testing had been satisfactorily performed at, or above, the specified flow
rates on the AFW and HHSl check valves with the exception of three AFW valves
that were normally tested at a lower flow rate due to normal system operating
alignment. Operating Manual Change Notice (OMCN) 2-98-063 was issued to test
2FWE*42B,43B, and 44B. The OMCN also tested the other AFW system check
valves. The insper: tors reviewed the completed OMCN and determined that, based
on the recorded values, the valves had passed more that the minimum flow required
(greater than 233 gpm).
CR 980169 and 980119 concerned verification of flow paths of component cooling
water and service water / river water for both units on a monthly basis as required by
TS. The inspectors reviewed the licensee's findings and corrective actions. The
licensee had identified multiple valves (over 100) that were not verified as required
I
,
(.
.
19
and several power operated valves that were not full-stroke tested every 18 months
as required. The licensee also performed an engineering review to establish safety I
related systems and systems that should have cooling flow verified to ensure that I
those systems were in the condition / temperature assumed in the accident analysis,
although those systems may not be needed for accident mitigation. The licensee
performed position verification checks on all additional valves identified by their
review. None were found in an incorrect position. The inspectors reviewed several -
of the licensee's revised surveillance procedures for Unit 2; and, using P&lDs,
selected several valves that supply cooling water to safety related components to
- verify that those valves were included in the listing of valves to be verified. No
! discrepancies were identified.
The issues identified in the above CRs involve the improper implementation of the
applicable Technical Specification surveillance requirements which are examples of
violations of NRC requirements. These violations were licensee identified through
l corrective actions taken to address a previous escalated enforcement action (EA 97-
255) documented in NRC Inspection Report Nos. 50-334(412)/97-02and NRC letter
to Mr. J. Cross dated July 3,1997. The root cause for these violations is similar to
l that for the initial problem. The safety significance of the initial problem remains
!'
unchanged. Immediate corrective actions were properly implemented and long-term
actions to preclude recurrence are in progress. Therefore, consistent with Section
l Vll.B.4 of the NRC Enforcement Policy, enforcement discretion is exercised and no
l
violation will be issued (NCV 50-334(412)/98-01-02).

indeoendent Verification of TS Surveillance Review
l
l In addition to the review of the deficiencies identified by the review team, the
! inspectors independently selected TS surveillance requirements of three systems for
L review. The surveillance requirements were compared by a line by line review of
I the TS which were compared with the TS review team's records of their review.
The inspectors found that each line of the TS surveillance requirements had been
- reviewed and that associated surveillance procedures had been compared with the
i: surveillance requirements to ensure compliance. CRs or procedure revisions had
- been initiated by the review team to correct identified discrepancies.
c. Conclusions
i
I
L The inspectors determined that the TS review team conducted a thorough and I
detailed review of the TS surveillance requirements and associated surveillance l
procedures to ensure that surveillance requirements were satisfied. Licensee
j actions to identify and resolve problems were comprehensive and technically
correct. However, the full implementation of the Technical Specifications
,
surveillance review team was not completed in a timely manner, such that the
h
licensee's January 30,1998, commitment date could be met. The late ~ 4
implementation and a larger than anticipated problem resulted in the licensee l
- requesting a commitment date extension from the NRC. Independent evaluation of !
the surveillance review team's activities did not identify any discrepancies in their

program.

E1.1 Uodated Final Safety Analysis Reoort and System Safety Functional Evaluation
Ooen item Review-
a. insoection Scoos (37551)
The licensee was in the process of reviewing all open items from their Updated Final
Safety Analysis Report (UFSAR) review project and from a Safety System
Functional Evaluation (SSFE) review of the emergency diesel generator and 4 kV
station service system. The inspectors independently reviewed over 30 of the open
items. The items were reviewed to ensure the licensee properly reviewed,
dispositioned, and prioritized the items,
b. Observations and Findinas ,
.I
The UFSAR and SSFE open items were verified to be generally properly prioritized,
reviewed, and dispositioned. More significant items were identified to management
through the normal corrective action process. The inspectors also observed that the
method for initial identification of UFSAR open items effectively used system
engineering knowledge and input.
The inspectors noted two exceptions to the generally effective evaluation of the
open items. The inspectors reviewed a UFSAR open item on discrepancies between
the UFSAR and other design basis documents for required Unit 1 river water flow.
The initial evaluation noted that it was a descriptive issue only and that there was
no operational or design non-conformance. The inspectors noted an additionalissue
with river water flow assumptions. The calculation for the minimum operating point
(MOP) curve did not consider all possible lineups of the system. The inspectors
determined based on available data that the discrepancy was minor and appeared
not to affect the current MOP curve. The licensee wrote a condition report to
'
address the issue and planned to revise the calculation that supported the MOP
curve prior to Mode 4. The issue was addressed in Condition Report 980507.
The inspectors reviewed an SSFE open item which noted that the minimum voltage
required for safety-related equipment was greater than the TS requirements for ;
degraded voltage relay setpoints which generate an EDG automatic start signal. !
Inspectors originally questioned the degraded voltage setpoints during a 1991
inspection. In November 1993, engineers evaluated the issue and determined that j
the minimum voltage setpoints should be a,dministratively controlled at higher values !
until the TS values could be revised (trip setpoint of > 94% and allowable values of .l
,
> 93%). The TS requirements had a trip setpoint of > 90% and an allowable value
L of > 88% for the degraded voltage relays.
l
l
. _ .
.
21
The inspectors reviewed the administrative controls associated with higher
setpoints. The data sheets for the maintenance surveillance procedures were i
revised to include the higher values. The inspectors determined that the controls
were inadequate due to: 1) the reference in the procedure data sheet section
identified the TS values (which are non-conservative) and not the determined design
basis values; 2) the procedure did not have explicit acceptance criteria that the
values would be within the band listed in the tables; 3) the step to notify the shift
supervisor that the relay was below allowable values identified the TS value rather
than the design basis valua. Based on the above, the potential existed that the shift I
supervisor would not have been notified and would have failed to recognize that the
allowable values were not met. The inspectors reviewed completed procedures
from 1997 and 1998 and data from 1995 and 1996. The inspectors did not
identify any instance where values dropped below the new calculated allowable
values.
A TS amendment request to revise the degraded voltage relay setpoints had not
been submitted. Several reasons were given for the delays including replacement of
relays with rnore accurate relays (1996) and rework of the design calculations. In
1995, a corrective action tracking item was initiated that required Engineering to
request a TS change from Licensing. The original due date was August 1996. The
due date was changed four times and had not been completed. The Plant Support
Engineering Director informed the inspectors that the item will be completed after
gathering additional data on voltage imbalance on the electrical bus to further define )
the setpoint inaccuracy range. The SSFE open item was considered closed because
the issue was being tracked by the licensee's corrective action process. The
inspectors noted that the SSFE review was not of sufficient depth for this open item -
to address the procedure deficiencies and the longstanding TS deficiency.
10 CFR 50 Appendix B Criterion XVI requires that measures shall be established to
assure that conditions adverse to quality, such as c'Miciencies, are promptly
identified and corrected. Failure to submit a TS arcendment request in a timely
manner after a known TS deficiency was recognized and failure to implement
adequate procedure revisions to ensure the revised setpoints were met was a
violation of 10 CFR 50 Appendix B Criterion XVI. (VIO 50-334(412)/98 01-03).
The inspectors noted that two other examples of failures to address known TS
deficiencies in a timely manner contributed to LERs in the last year (see Unit 1 LER
97-32 and Unit 2 LER 97-06). After discussions with the inspectors, the licensee
planned to perform a review of the engineering backlog to determine if any
additional known TS deficiencies existed. This action was appropriate.
c. Conclusions
The licensee recognized a TS deficiency regarding degraded voltage relay setpoints
, in 1993 and administratively controlled the setpoints through revisions to the
maintenance surveillance procedures. The procedure revisions were inadequate end
a TS amendment to change the relay setpoints had not been submitted. The failure

to address a known TS deficiency in a timely manner and to establish adequate
administrative controls to maintain the setpoint was a violation. Two other
examples of failures to address known TS deficiencies in a timely manner
contributed to LERs in the last year.
E1.2 Emeroency Diesel Generator Motor Ooerated Ground Switch and (Uodate) EA 50-
334(412)/97-255-01013
a. Inspection Scooe (37551)
The inspectors reviewed an open item from the TSSRT (previously discussed in
Sections 08.1 and M8.1) on the Unit 1 and Unit 2 emergency diesel generator
(EDG) motor operated ground switch. The inspectors reviewed the Unit 2 safety
and licensing position paper, technical evaluation report (TER) 11704, associated
10 CFR 50.59 evaluations, and relevant design basis documents (IEEE, Regulatory
Guides, etc.). In addition, the inspectors attended the Onsite Safety Committee
evaluation of the revised TER and 10 CFR 50.59 evaluations.
b. Observations and Findinos
The licensee committed to perform a TS surveillance review as part of their
response to Notice of Violation EA 97-255. As part of their ongoing review, the
licensee identified that the Unit 1 and Unit 2 ground overcurrent protection was not
tested as required by TS 4.8.1.1.2.b.4. The TS required that on a loss of power to
the emergency busses, all EDG trips with certain exceptions are automatically
disabled. The ground overcurrent protection had not been tested since original
startup for both units. The cause was inadequate interpretation of TSs which
resulted in inadequate procedures. The licensee noted that the other protective
signals were appropriately tested. The ground switch was closed only during
surveillances.
Failure to comply with TS 4.8.1.1.2.b.4 was a violation of NRC requirements. This
violation was identified through corrective actions taken to address a previous
escalated enforcement action (EA 97-255) documented in NRC Inspection Report
Nos. 50-334(412)/97-02and NRC letter to Mr. J. Cross dated July 3,1997. The
root cause for this violation is similar to that for the initial problem. The safety
significance of the initial problem remains unchanged. Immediate corrective actions
were properly implemented and long-term actions to preclude recurrence are in
progress. Therefore, consistent with Section Vll.B.4 of the NRC Enforcement Policy
enforcement discretion is exercised and no violation will be issued (NCV 50-
334(4121/98-01-04).
The review also identified that the ground switch which provided the isolation
feature for the overcurrent protection was a Quality Assurance (QA) category 2
switch. The licensee identified that the switch was QA category 2 in 1992 and at
that time recommended that the diesel be declared inoperable during the normal
monthly surveillance testing. The switch was only closed during surveillance
testing. The licensee did not recognize the failure to perform the surveillance

j testing of the switch in the 1992 review. Licensing reviews concluded that the Unit
l 2 EDG needed to be operable during surveillance testing to comply with Regulatory
'
Guide 1.9, Rev. 2, and IEEE-387-1977 (referenced by Regulatory Guide 1.9, Rev.
2). However, Unit 1-was not affected since it did not commit to Regulatory Guide
1.9. The licensing department recommended an upgrade of the EDG ground
, overcurrent trip bypass equipment to QA category 1 classification to return the
i
design to the originally intended concept and licensing bases. Engineering created a
design change that did not change the ground switch to QA category 1. Instead,
l the modification (Technical Evaluation Report (TER) 11704) isolated the overcurrent
protection signal with a QA category 1 component. The TER was installed.
The inspectors reviewed the TER after final approval through the Onsite Safety
Committee. The purpose of the TER was to restore the overcurrent trip isolation to
l a QA category 1 isolation. The inspectors questioned whether all failure modes of
the QA category 2 ground switch and ground switch resistor were considered in the
design modification since the design modification was apparently fixing" the lack
of a QA category 1 ground switch in the original design. The engineers did not
consider the failure modes in their 50.59 analysis prior to TER implementation,
because they felt they were outside of the TER evaluation. The inspectors
determined that the engineers had forwarded the TER for approval and
implementation despite knowing that additional potential failure modes of the
ground switch existed, but had not been fully evaluated. The inspectors determined
that the 50.59 analysis was too narrowly focused. The engineers subssquently
'
determined that the failure modes identified by the inspectors would not affect the
EDG.
Subsequent to TER installation, the engineers identified an additional failure mode
that had the potential to significantly damage the EDG during surveillance testing if
a fault occurred on the 4 kV line. This new failure mode was a direct result of the
design modification. The inspectors recognized that the licensee identified this new
subtle failure mode through good engineering investigation. In addition, engineers
identified the new failure mode prior to post-installation operability testing.
The engineers also determined that, based on review of Regulatory Guide 1.9,
Rev. 2, Regulatory Guide 1.108, Rev.1, IEEE-387-1977, and IEEE-279-1971,the
design basis requirements were as follows: 1) surveillance testing does not prevent
the EDG from automatically starting in response to a safety signal (does not require
operability of the EDG during surveillances; therefore, a category 1 isolation is not
required); 2) all protective signals should be in force during surveillance testing; and
3) the bypass circuitry should satisfy the requirement of IEEE-279-1971 at the
diesel generator system level. The engineers determined that the original design
met the design basis requirements. The engineers also concluded that TER 11704
did not meet the design requirements in that all protective signals would not have
been operable during surveillance testing. In addition, the 50.59 evaluation was not
accurate'in that all failure modes were not evaluated. The engineers created a new
TER to restore the original design. The inspectors noted good OSC questioning
,
.
24
during the revised TER review. The reversal of the design change was completed
prior to surveillance testing on the EDG; therefore, no adverse safety consequences
resulted. The engineering group incorporated lessons learned from this event in
their training.
10 CFR 50, Appendix B, Criterion 111 (Design Control), requires, in part that design
changes shall be subject to design control measures commensurate with those
applied to the original design. In this case the design control measures for a
modification to the Unit 2 emergency diesel generator (EDG) ground overcurrent trip
isolation feature were inadequate. Specifically, the failure mode analysis for this
design change did not evaluate failures of the quality assurance category 2 ground
switch and resistor. The failure mode analysis also did not identify or evaluate an
additional failure mode which had the potential to damage the EDG during
surveillance testing if a fault occurred on the 4 kV line. This was a violation of
10 CFR 50, Appendix B, Criterion lli (VIO 50-334(412)/98-01-05). The failure to
understand the design and licensing bases prior to performing the modification was
a weakness.
c. Conclusions
'
The Technical Specification surveillance review team identified that the Unit 2
emergency diesel generator ground switch was not tested as required by Technical
Specifications. This was attributed to inadequate implementation of TS
requirements into surveillance procedures.
Engineers f ailed to fully evaluate all potential failure modes prior to installation of a
modification to the Unit 2 emergency diesel generator ground overcurrent trip !
isolation feature which was an example of inadequate design control and a
violation. Specifically, the failure mode analysis for this design change was too
narrowly focused in that failures of the quality assurance category 2 ground switch
and resistor were not fully evaluated. The failure mode analysis also did not identify
or evaluate an additional failure mode which had the potential to damage the EDG j
during surveillance testing if a fault occurred on the 4 kV line. !

R1 Radiological Protection and Chemistry (RP&C) Controls
a. Insoection Scoce (83750)
The inspectors reviewed the licensee's programs for internal and external dosimetry,
including personnel dosimetry records, calibration and utilization of whole body
counters, and respirator issue and maintenance. Additionally, the inspectors
reviewed current radiological work at both units and the most recent audit
conducted as part of the National Voluntary Laboratory Accreditation Program !
(NVLAP). The inspection was accomplished by a review of plant documents and !
procedures, interviews with personnel and walkdowns of the related areas.
i
b. Observations and Findinos ;
I
The licensee's principle means of determining qualitative and quantitative i
information on internal exposure is via the use of whole body counting. The !
I
licensee maintains two whole body counters, one using Nal(TI) detectors and the l
other intrinsic germanium. The Nal(TI) system is used regularly to perform routine
bloassays, and as a screening tool for potentialinternal exposures. The system has
been calibrated and is maintained in such a manner as to meet the necessary
sensitivities for the various radionuclides present in the plant. Documentation of the 1
annual calibration and a semi-annual calibration verification are maintained and
distributed to pertinent staff members and was reviewed by the inspector. At the
time of this specialist inspection, the licensee had just completed its calibration of
one of the counters and was preparing to start calibration of the second counter.
Source and background checks were performed every four hours during operation
by the licensee as a quality control measure. Documentation of ihese results was
readily available at the whole body count trailer where these two devices were
located. Currently, the computer that interfaces with the counters does not have
the capability to communicate directly with the licensee's health physics database,
so data transfer is by hand. During the spring and fall, availability of the counters,
especially the Nal(TI)-based system, is significantly diminished due to temperature
changes in the trailer which cannot be appropriately compensated for with the
limited HVAC system for this facility. However, no incidences of inaccurate
surveys of personnel were found by the inspectors.
The licensee's external dosimetry program utilizes thermoluminescent dosimeters
(TLDs) for dose of record, and electronic dosimeters for more real-time exposure
data. The licensee's program for external dosimetry was most recently reviewed by
NVLAP (Audit # 100521) on October 29-31,1997. Three deficiencies were
indicated in the audit report which required a licensee response. The licensee has
responded, as required, and has received its recertification. The licensee's health
i physics database incorporates results from the TLDs and the electronic dosimeters
'
to allow for tracing of worker exposures in near real-time. Additionally, this
database is utilized for RWP and ALARA review issuance and data tracking.
.
.
l. 26
The licensee utilizes and maintains a variety of respiratory protection devices,
especially a large number of self contained systems, due to the presence of sub-
atmospheric containment environments while at power. Annual training and fit test
programs are appropriately implemented and maintained. Data tracking and
issuance are currently performed using a specialized database, which is
incompatible with the main health physics database. This weakness is currently
being addressed by the licensee. During outage operations, a contractor is utilized
to perform respirator cleaning,' with 100% review of returned respirators conducted
by the licensee. The majority of respirators currently utilized by the licensee are for
industrial hygiene purposes, and are not needed for minimizing internal radionuclide
exposures.
The inspectors reviewed the licensee's established occupational exposure goals for -
1998. The site goal of 186 person-rem is based on a full year operating goal at
Unit 1 of 28 person-rem, a partial operating year goal at Unit 2 of 8 person-rem, and
a refueling outage (2R07) goal of 150 person-rem. Through the first seven weeks
of 1998, the licensee was ahead of its year-to-date projections due to the
unplanned shutdown of both units. At Unit 2, over 600 millirem had been
expended working on valve repair / modifications in the pressurizer cubicle. At
Unit 1, a system modification would also entail work in their pressurizer cubicle.
The licensee's annual goal does not include a contingency dose for unplanned
outages.
The inspectors conducted tours of various portions of the radiologically controlled
areas (RCAs) at both units. At Unit 2, the inspectors toured accessible areas of the
containment, auxiliary, waste, condensate, safeguards and turbine buildings. Of
particular note was the significant increase in the use of survey maps posted out in
the RCA. Each map was clearly dated, and based on inspectors' verification,
accurately indicated radiological conditions at the facility. The inspectors also noted
the detailed briefings being provided to workers entering the Unit 2 pressurizer
cubicle, and the use of an Al. ARA low dose waiting area for work there. At Unit 1,
the inspectors toured accessible RCA locations in the auxiliary, waste, fuel, j
safeguards and turbine buildings. As at Unit 2, local survey maps were now l
available to workers, in addition to those located at the main RCA entrance.
c. Conclusions
The licensee has established effective programs for external dosimetr*/, . internal
dosimetry through the use of whole body counting, and respiratory protection
program, improvements in radiological postings were also observed.

clear acrylic. During an in-office inspection on March 17,1998, the inspectors
reviewed the'results of the licensee's study to determine if spraying acrylic on the
filters would have an effect on the analytical results. The licensee compared the
analytical results of the air particulate filters with and without the acrylic coating.
The results were in agreement and the effect of the sample preparation method on
the analytical results was negligible. Nonetheless, the licensee discontinued the use
of the acrylic spray and revised the procedure, as appropriate. The inspector
concluded that no violation of NRC requirements occurred and this item is closed.
R8.2 (Closed) Violation 50-334/97-08-04: Radiological workers failing to follow
procedures. All licensee short and long-term corrective actions, except for reviews
.of their effectiveness during the upcoming Unit 2 refueling outage, have been
completed. Changes were made to the licensee's Health Physics Manual and
related implementing procedures. Survey maps of the RCA are now located
throughout the plant. No additional examples of workers in the radiologically
controlled areas (RCAs) without knowledge of their area exposure rates have been
identified. This item is closed.
