EXECUTIVE SUMMARY
Crystal River 3 Nuclear Station
NRC Inspection Report 50-302/96-08
l
This integrated inspection included aspects of licensee operations,
'
i
l engineering, maintenance, and plant support. The report covers a four week I
period of resident inspection; in addition, it included the results of
announced inspections by a reactor inspector, a reactor engineer, a visiting
resident inspector, and a senior radiation specialist.
Operations
The plant staff's response to a main condenser tube rupture event and a plant
transient due to a governor valve component failure were considered
appropriate. However, there was a concern regarding an operating crew that
did not implement a valid abnormal procedure because they were not comfortable
with it. (paragraph 01.1)
An Operations self-assessment appeared to be of insufficient depth. There
were no findings identified, although recent NRC inspections have identified
problem areas. (paragraph 07.1 and 07.2)
Maintenance
The vital battery charger change out work was accomplished in a professional
manner, with good project manager oversight. (paragraph M1.1)
A Weakness was identified in maintenance personnel communications with
operators during the conduct of a surveillance. (paragraph M3.1)
An Inspector Followup Item (50-302/96-08-02) was identified for the followup
of a permanent fix for thermal relief protection for reactor building cavity
cooling piping. (paragraph M8.2)
Interim corrective actions for a deficiency regarding the use of non-safety
related positioners on safety related valves (identified by the Integrated
Performance Assessment Process team as Unresolved Item 50-302/96-201-04) were
inspected and found to be acceptable. (paragraph M8.3)
Enaineerino
A Weakness was identified in the Problem Report tracking system in that
incomplete corrective actions for make-up system audit findings were closed
out as complete. (paragraph E8.1)
A Violation (50-302/96-08-01) was identified for failure to take timely
corrective actions for make-up system audit findings and excessive vibration
,
on a spent fuel pump cooling fan motor. (paragraphs E8.1 & E2.1)
l
l
i
l
FPC 2
Plant Support
Inspectors observed that calibration of Reactor Building Radiation Monitor
process was adequate. (paragraph R2.1)
The 1995 Annual Radiological Environmental Monitoring and Annual Radiological
Effluent Monitoring Reports met Technical Specification requirements, and did
not report any adverse radiological trends. The licensee appeared to be
adequately managing radiological effluents to maintain offsite doses as low as i
reasonably achievable. (paragraph R3.1 and R3.2) '
Shipping papers for the transportation of radioactive material, and
radioactive waste met regulatory requirements. (paragraph R3.3)
A weakness was identified in that a Quality Assurance audit failed to properly
identify that two PCS issued during the audit should have been characterized 1
as prs. (paragraph F7.1)

01 Conduct of Operations
01.1 Review of Previous Operational Events
l a. Inspection Scope (92700)
The inspectors reviewed a Main Condenser Tube Rupture Event, and a
l Governor Valve transient to determine if the licensee responses to the
events were adequate and met regulatory requirements, license
,
conditions, and commitments and to verify that the licensed operator's
l performance was adequate to ensure safety.
b. Observations and Findings
The inspectors reviewed the Main Condenser tube rupture event which
occurred on January 9, 1996, in detail. This event was previously
described in NRC Inspection Report (IR) 50-302/96-03, paragraph 2.4.
l The inspectors interviewed some of the operators involved, and reviewed
the plant's procedures and the licensee's investigation. The inspectors
found that the licensee responded to the event in accordance with the
existing procedures with the exception of implementing abnormal
procedure (AP) AP-510, Rapid Power Reduction, Revision 00, dated .
December 14, 1995.
'
During the event the operators had discussed alternatives such as
tripping the reactor early and initiating Emergency Feedwater (EFW), but
l did not feel the event warranted placing the plant in such a transient,
and deviating from plant procedures. The operators also stated that the
increased attention to procedural compliance affected the decision not
to initiate EFW. The licensee had a valid procedure for conducting a
rapid shutdown which was appropriate for the existing situation.
Procedure AP-510, Rapid Power Reduction, Revision 00, was issued on
December 14, 1995. If the licensee staff had implemented procedure AP-
510, the plant could have been in Mode 3 within one hour of commencing
the shutdown, instead of taking four hours and 40 minutes. This would
! have significantly reduced the amount of salt water that entered the
Once Through Steam Generators (OTSGs). The operators stated that they
did not implement procedure AP-510 because they had not yet received
simulator training on the new procedure, and that one of the reactor
operators (R0s) was not a normal member of the crew. The operators on
this crew had only received on shift training for procedure AP-510, the
crew's simulator training was scheduled for their next training

4 rotation. The inspectors were concerned that a crew would not implement
a valid AP because they were not comfortable with using a newly issued
'
procedure. The inspectors found that the delay in feeding the OTSGs
with clean water after the shutdown was due to: 1) the licensee staff
prioritization of minimizing the transient on the plant, 2) developing a ;
procedure for feeding the OTSGs with the EFW system, and 3) a lack of i
management direction in emphasizing the importance of initiating clean
<
The inspectors concluded that the plant staff responded to the plant i
transient adequately using the existing plant procedures and equipment.
-
NRC Inspection Report 50-302/95-21 described the " Conservative and i
thorough management of the shutdown" as a strength. However, use of
i procedure AP-510 to shut the plant down in a more expeditious manner
'
could have been more appropriate to reduce chloride intrusion into the
OTSGs. In addition, the licensee could have been more prompt in
developing and implementing the procedure to feed the OTSGs using EFW.
<
The inspectors found that no safety limit or procedural violations
occurred during this event. The inspectors also noted that the licensee
,
l
issued procedure AP-610, Waterbox Tube Failure, on April 8, 1996. This
,
procedure was developed from the lessons learned in this event, and
provided explicit guidance to the operators for condenser tube failures. ,
The inspectors also reviewed the governor valve event which occurred on l
May 20, 1996. This event was previously described in NRC Inspection '
Report 50-302/96-05. The event caused three power transients within a l
4
30 minute period. The inspectors interviewed the operators involved and
the plant's investigation report. The inspectors verified that the
plant never met the conditions to initiate a manual reactor trip as ;
specified in procedure AI-0505, Conduct of Operations During Operational '
'
Events and Emergency Events.
'
The inspectors determined that the operators adequately controlled the l
plant, and that their actions were appropriate. The inspectors also '
4
'
determined that while a reactor trip may have been considered a more !
conservative response, it would have initiated a larger transient on the )
a
plant than the power swings caused by the governor valve. The
'
inspectors asked the operators if any other actions were considered in
response to the event. The operators all stated that the option of
- using the test feature to slow close the governor valve was considered, i
but no one mentioned it until the post-event critique. Further l
discussions revealed that the senior reactor operator (SR0) did not !
'
pursue the slow close option because it was contained in a performance
,
test (PT), and operators could not use the PT in response to the event.
4
The operators reduced power to close the governor valve, and then
isolated electro-hydraulic control (EHC) oil to the valve. The event
, was witnessed by the resident inspector who was in the control room at i
j the time. He considered the crew's response to the event demonstrated
technically sound judgement.

c. Conclusions
i
The inspectors recognized that the Emergency and Abnormal procedure I
network was not intended to be the optimal recovery strategy for any )
single event, but rather an enveloping strategy for a family of events.
While the inspectors found a procedure whose use may have been more
appropriate, the licensee appropriately followed an existing procedure.
The licensee has taken the lessons learned from this event and developed
a more appropriate strategy for combatting this specific type of event.
The inspectors noted that any potential consequences of the chloride
intrusion were longterm and could not be evaluated during the
inspection. The inspectors concluded that the licensee's response to
both events was adequate.
06 Operations Organization and Administration
06.1 Operator Shift Schedulina
a. Inspection Scoce (71707)
Technical Specification 5.2.2.e requires that the amount of overtime
worked by unit staff members performing safety related functions shall
be limited and controlled in accordance with approved administrative
procedures.
b. Observations and Findinas
Licensee procedure 01-11, Operations Schedules, section 4.0, Overtime
Policy, provides guidance for the operations staff for the control of
overtime. The requirements in 01-11 are in accordance with Genetic
Letter (GL) 82-12, Nuclear Power Plant Staff Working Hours, as required
by the NRC order transmitted on May 14, 1983, confirming the commitments
to implement NUREG-0737 post-TMI related requirements contained in a
letter from the licensee responding to GL 82-10.
01-11 requirements address the issue of controlling overtime to avoid
fatigue in operators and a degradation in their performance. 01-11
limits include:
e An individual should not be permitted to work more than 16 hours1.851852e-4 days <br />0.00444 hours <br />2.645503e-5 weeks <br />6.088e-6 months <br />

t .
l
The licensee's practice is to have the Manager of Nuclear Plant
Operations Support review shift schedules for compliance and approval
- prior to issuance. The inspectors reviewed the shift schedules for the
operations department since start up from the recent refueling outage. ;
! During the refueling outage, large amounts of overtime were routinely i
scheduled. Since the outage, it has been determined that time in excess I
of 60 hours6.944444e-4 days <br />0.0167 hours <br />9.920635e-5 weeks <br />2.283e-5 months <br /> in any seven day period has been routinely scheduled, for
the licensed R0s and SR0s. During this period, it has been a common
practice to schedule shift periods from five to nine days long. No 4
times'were found where more than 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> were worked in a.seven day '
L period, but a large number of times where a licensed operator worked
! between 60 and 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> were found. A review of the NLO schedule
! revealed that the NL0s rarely worked more than 60 hours6.944444e-4 days <br />0.0167 hours <br />9.920635e-5 weeks <br />2.283e-5 months <br /> in a seven day
period.
l c. Conclusions
A PC has been issued to address concerns with the scheduling practices
in the operations department, including overtime control practices.
Actions have been taken to address the concern expressed in the PC,
including maintaining support personnel with active licenses to provide
-additional' coverage and starting a new license training class to provide
additional personnel for shift coverage. The inspectors have concluded
'
that the licensee did not violate any overtime restrictions but the
continued use of routine overtime provided the potential for degradation
of operator performance.
07 Quality Assurance in Operations
07.1 96-02-REFL. Audit Report of 1996 Refuel Outaae
a. Inspection Scope (40500)
The inspectors reviewed the-licensee quality assurance (QA) audit for
the 1996-refueling outage, 96-02-REFL. The audit included, but was not
limited to, field observations, review of the plant shutdown, control of.
contractors, nuclear quality control activities, ISI activities, fuel
movement, adherence to technical specifications, corrective actions, and
maintenance activities,
b. Observations and Findinas
~ As a result of the audit, five findings (characterized by the Licensee
as violations), fifteen weaknesses, numerous negative comments, and
I '
I
! ,
5
fifteen strengths were identified. Several conclusions were identified
by the licensee in the report:
1. Ineffective training and understanding of procedures was evidenced
by the problems with foreign material exclusion.
2. Lack of attention to detail in failures to complete signoffs as
actions occurred.
3. Management expectations in the areas of communications, self
checking and the utilization of available resources were not
consistently met.
4. Management oversight is lacking as evidenced by improper reviews
of procedures.
c. Conclusions
The inspectors discussed the audit with the audit team leader and
reviewed the audit report. There were many individual findings,
however, conclusions drawn tended to be specific to the identified items
(a list), without any programmatic findings discussed. Plant management
is aware and is currently assessing these findings, therefore no NRC
follow-up will be taken.
07.2 Operations Self-Assessment
a. Inspection Scope (405001
The inspectors reviewed the operations self-assessment performed at the
site by current and formerly SR0 licensed individuals on loan from other
licensees. The areas assessed by the team included: professionalism and
skills of plant operators, self checking and questioning attitude,
interface and communications, conservative decision making, shift
turnover, control room traffic, and procedural adherence and usage. l
!
b. Observations and Findinas
The assessment team provided a number of recommendations, areas for
improvement, and strengths. No findings or problem reports were
identified as a result of this assessment. A number of recommendations
were provided, which have the potential to improve the effectiveness of
operations. However, no programmatic assessments were evident, although
a number of areas for improvement were identified.
c. Conclusions
The operations self-assessment, while providing a number of observation;
characterized as strengths, weaknesses, areas in need of improvement, or
recommendations; did not provide an assessment of operational programs.
There were no problem reports issued as a result of the assessment.
Three PCs were issued as a result of the assessment, two on recurring
recorders problems in the main control room. No conclusions were
reached on the overall effectiveness of the licensee's operations
department, by the self-assessment.

Recent inspections by the NRC have identified multiple problems,
! including procedural adherence, communications, and log keeping
practices. Even though recommendations exist in these areas, no
assessment of the current effectiveness, nor any examples of specific
problems were identified.
l The performance of the self-assessment was a good initiative, but the
implementation was not of sufficient depth.

08 Miscellaneous Operations Issues
08.1 (Closed) Licensee Event Report (LER) 50-302/96-017-01. Reactor Trio on
Hiah Reactor Coolant Pressure Durina Turbine Testina Caused by Debris in
Manual Isolation Valve
a. Inspection Scope (92901) i
This event was discussed in IR 50-302/96-05. The inspector performed
additional followup interviews with the operators to clarify their-
response when the main steam safety valve (MSSVs) did not operate at the
proper setpoints.
b. Observations and Findinas
The inspector determined that the operators followed plant procedures
and that their actions were adequate.
c. Conclusions
This LER is closed.
08.2 (00en) Violation (VIO) 50-302/93-16-07. Inadeauate Emeraency Operatina I
Procedure (EOP) and AP Procedures
4
a. Inspection Scope (92901)
This item concerned multiple examples of a violation of 10 CFR 50,
Appendix B, Criterion V. The inspector reviewed the remaining
procedures cited in the violation, AP-581, Loss of (Non-Nuclear
Instrumentation power supplies) NNI-X, and AP-582, Loss of NNI-Y.
b. Observations and Findinas
The inspector noted that the procedural discrepancies noted in the i
Notice of Violation had been corrected for these procedures. However,
an outstanding Request for Engineering Assistance (REA) 95-0406 was
initiated in April 1995, and has yet to be completed. This item
requested that an engineering review be conducted on the above
procedures to ensure the lists of reliable and unreliable
instrumentation contained in the above procedures were correct.
.
i

The inspectors witnessed portions, on various days, of the performance
of WR NU 0331781, Vital battery charger IF change out, per Modification
Approval Record 93-05-07-01.
l
b. Observations and Findinas
The inspectors reviewed the work package and verified that all reviews l
and approvals had been received prior to the beginning of work.
The licensee utilized SMC support personnel to perform this task. The
inspectors verified that the personnel were qualified by the licensee's
program and were the same personnel used to change out battery chargers ,
lA, 18, 1C, and 10 during the recent refueling outage,
c. Conclusions
The vital battery charger change out work was accomplished in a
! professional manner, with good project manager oversight.
i No problems were identified.
M1.2 Shoot and Clean Nuclear Services Closed Cycle Coolina Water System Heat

a. Inspection Scope (62707)
The inspectors witnessed the performance of portions of WR NU 0336700,
Shoot and Clean SWHE-1D.
b. Observations and Findinas
A review of the work package revealed that all reviews and approvals had
been received prior to beginning the task. The inspectors discussed the
task with the technicians.
,
8
c. Conclusions
The inspectors determined, that the technicians were knowledgeable of
the requirements and performance of the work. No problems were
identified.
M3 Maintenance Procedures and Documentation
M3.1 Surveillance Observations
a. Inspection ScoDe (61726)
The inspectors witnessed the performance of surveillance procedure, SP-
130, Engineered Safeguards Monthly Functional Test. This procedure was
performed to verify operability of the Engineered Safeguards Actuation
System (ESAS) instrumentation, as required by TS 3.3.5, ESAS
Instrumentation.
b. Observations and Findinas ,
The inspectors witnessed the performance of SP-130, Engineered
-
Safeguards Monthly Functional Test. The inspectors noted some r
weaknesses with the instrument technicians communications. When the !
technician asked the R0 to verify the reactor building pressure, he did_
not specify the instrument to be used until the R0 asked if one was l
.specified in the procedure. -While performing steps of the procedures :
which would cause an alarm, the technician would just state that .there i
would be noise coming,-and did not specify which alarms to expect, until ;
the R0 requested that the technician be more specific. Even though j
there were no problems with the completion of the surveillance, the.R0 i
had to prompt the technician for more accurate communications.
c. Conclusions
Weaknesses were identified with the instrument technician communications
skills, but the R0 prompted better communications during the performance
of the test.
M8 Miscellaneous Maintenance Issues
a. Inspection Scope (92902)
A reactor trip followed by one steam generator dryout due to the failure I
of one main steam safety valve to close occurred at Arkansas Nuclear I
on May 19, 1996. -The main steam safety valve had apparently been
maintained improperly, allowing a stem nut (release nut) to move, i
preventing valve closure. An Industry Report had previously been issued i
due to the same failure mechanism having occurred at Crystal River. I

b. Observations and findinas
In IR 50-302/96-06, Paragraph M8.1, the residents discussed their review
of applicable licensee documents, and concluded that the corrective
actions taken for the main steam line safety valves release nut
restraint problem were adequate to prevent recurrence. Subsequently,
the residents walked down the main steam line safety valves and verified
that the release nuts were properly restrained by the release nut cotter
pin.
c. Conclusions
No further follow-up of this issue is required.
M8.2 Cavity Coolina Pipina Thermal Relief Protection
a. Inspection Scope (62703)
The inspector reviewed the licensee's interim corrective actions
associated with a potential concern associated with containment
integrity. During the recent NRC IPAP inspection an NRC inspector had
questioned the adequacy of the existing cavity cooling (CI) piping
configuration associated with AHHE-14A and AHHE-14B within the Reactor
Building. This system provides cavity cooling during power operation
and prnvides no post-accident safety related function. The specific
concern was that the CI piping or cavity coolers could fail following a
loss of cooling accident (LOCA) due to over pressurization after
containment isolation. CI piping within the Reactor Building was not
provided with thermal relief protection.
b. Observation and Findinas
The inspector reviewed Problem Report (PR) 96-0261 which was issued by
the licensee to address this issue along with the licensee's interim and
proposed long term corrective actions and determined that they were
adequate. The licensee evaluated this issue and determined that
containment integrity would not have been affected by a failure of the
CI piping located within the reactor building (RB). However, the
licensee also issued temporary modification, (T-MAR) T96-07-16-01, to
provide interim thermal relief protection for the CI piping in the
containment. The inspector reviewed this T-MAR along with maintenance
work request WR 0336793 which implemented this temporary modification.
'
This WR added CI thermal relief valves, CIV-279, 280, at AHHE-14A and
148. The relief valves were added downstream of piping vent valves,
CIV-90 and 91, and the vent valves administratively controlled under the
licensee's equipment clearance program. Installation of this T-MAR
required the licensee to modify their system venting instructions to
allow removal of a relief valve for venting purposes. The inspector was
further informed that a permanent plant modification would be issued at
a later date to replace this T-MAR.

c. Conclusions
The inspector determined that the licensee's interim corrective actions
were acceptable. IFI 50-302/96-08-02, Reactor building cavity cooling
piping thermal relief protection, will be issued to track permanent
resolution of this concern.
M8.3 Non Safety-Related Positioners on Safety-Related Valves
a. Inspection Scope (62703) I
!
The inspector reviewed the licensee's interim corrective actions j
associated with a concern associated with the safety-related and non- !
safety-related interface on Decay Heat Closed Cycle Cooling valve
positioners and whether a failure of the valve positioner could
potentially result in a failure of the associated valve to remain in the
correct position during a LOCA. During the recent NRC IPAP inspection,
an inspector had questioned the adequacy of the configuration associated
with the non-safety related positioners installed on the DC outlet
valves, DCV-177 and DCV-178, and bypass valves, DCV-17 and DCV-18, for
the Decay Heat Removal Heat Exchangers. During a review of the subject
valves it was discovered that although control air to the pneumatic
controls were isolated, the supply air to these non safety-related
positioners was not normally isolated.
.
'
b. Observation and Findinas
The inspector determined that PR 96-0220 had been subsequently issued by
the licensee to address this concern. The licensee's interim resolution
of this issue was to temporarily close IAV-228 to isolate the supply air
to the pneumatic controls to the valves and place IAV-228 under
administrative control by use of an equipment clearance.
These DC valves are required to be in their safety related ES positions
during a LOCA to provide maximum cooling flow to the DH heat exchangers
(DCV-17 and 18 full closed with DCV-177 and 178 full open). However,
these valves also have a non-safety related function in that they are
throttled to control the rate of decay heat removal from the reactor
core during plant shutdown. During power operation these valves were
previously failed to their safety related position by isolating control
air to the positioners by Procedure OP-404, Decay Heat Removal System,
while supply air was not isolated. The actual valve position on loss of
air would be determined by the actuator spring. Although the
positioners were not considered safety related, the valve actuators were
classified by the licensee as safety-related.
The inspector reviewed plant modification MAR 94-09-02-01, DC Cooling
Instrumentation Enhancement. The inspector determined that this MAR,
when implemented, will simplify the control logic of DC cooling to the
heat exchangers by permanently removing the existing pneumatic
temperature controller and piping the emergency preparedness (E/P)
output directly to the valve positioners. This modification will remove
the temperature control function and allow the operator to command a
11
valve position demand signal directly to the valve positioners. This
modification would also result in a change in the method of failing the
valves to their safety-related ES positions by isolating DCV-194 and
DCV-196 and venting of supply air by opening DCV-195 and DCV-197 rather
than only isolating the input control air signal to the positioners.
This would isolate all air to the valve positioners and no longer
require closure of IAV-228.
c. Conclusions
The inspector determined that the licensee's interim corrective actions
were acceptable. Additionally, the inspector determined that completion
of this MAR was listed as part of the corrective action plan (CAP) for
PR 96-0220 with a completion date of September 30, 1996. This item was
identified by the IPAP team, and will be tracked as part of IPAP Open
Issues. (See IPAP URI 50-302/96-201-04.)
M8.4 Safety-Related Battery Chargers
a. Inspection Scope (62703)
The inspector reviewed the status of licensee actions to address an
industry issue which could potentially affect reliability of the safety-
related battery chargers. During installation testing of replacement
safety-related 125 VDC battery chargers at Salem, it was found that
three wire lugs were landed on a terminal with insufficient thread
engagement to the terminals. This deficiency could have resulted in
failure of those battery chargers during power operation. All six
safety-related chargers at Crystal River were recently replaced with new
battery chargers from the same manufacturer as those at Salem.
b. Observation and Findinas
The inspector was informed that licensee management had contacted Salem
management, and had determined that the actual problem was that up to
three wire lugs were landed on common screw terminal connections on the
battery charger high voltage shutdown board. This board is located
within the alternating current (AC) side of the battery chargers and
provides high AC voltage input protection for the battery and charging
circuits. The terminal screws were not of sufficient length to provide
adequate thread engagement with three wire lugs landed on the associated
terminal.
Each of Crystal River's two safety-related batteries is supported by two
125 VDC chargers and a single 125 VDC spare charger (total of six
chargers). The safety-related chargers at Crystal River are from the
same manufacturer but are a different size and model (Charter Power
Systems Model ARR200F) than those used at Salem (Charter Power Systems
Model ARR300F). However, the non-safety related chargers in use at
Crystal River are the same type chargers as those being questioned at
Salem. The inspector was informed that the non-safety related chargers
had also been inspected and no loose connections were identified.

However, the engineer noted that there were three wire lugs landed on
i
common screw terminal connections on the high voltage shutdown boards on
- these chargers. A precursor card had been written to address this
i potential problem with the non-safety related chargers at Crystal River.
'
The inspector was informed that a licensee engineer had inspected all
six safety-related chargers and verified the adequacy of all screw
.
terminals located within the safety-related chargers. The inspector
interviewed the engineer that conducted these inspections. The engineer
informed the inspector that all screw terminals located on the high
voltage shutdown boards had less than three wire lugs installed. The
inspector was also informed that each of these chargers did have three
wire lugs landed on a common terminal on the power terminal block. The
lug connections on these terminals had been closely examined by the
licensee and the licensee determined that the installations were
acceptable. The power terminal blocks and connections appeared sound
, and the type and length of the screw used to secure the wire lugs was
verified to be of sufficient length to allow full thread engagement with
three wire lugs attached by a common terminal screw. Additionally, the
engineer verified all wire terminal points on the six safety-related
i
chargers which utilized lug nuts had full thread engagement.
The inspector selected one safety-related charger, DPBC-1E, which had
been previously inspected by the licensee and visually inspected all
internal wire lug connections. The inspector verified that all screw
terminals and lug nut installations were acceptable.
,
c. Conclusions
J
The results of the inspector's observations were consistent with the
results from the inspection performed by the licensee engineer. Based
,
on this review the inspector determined that this potential industry
1 issue had been adequately dispositioned by the licensee. No further
review of this issue is required.

E2.1 Deqraded Safety Related Eauipment
,
a. Inspection Scope (37551)
On July 17, 1996, the inspectors reviewed the licensee's Plant Equipment
Condition Monitoring Program report dated July 12, 1996. This report is
a quarterly report summarizing the plant equipment condition monitoring
program.
- b. Observations and Findinas
The inspectors noted that AHF-8A, Spent Fuel Pump Motor Cooling Fan 8A,
continued to be operated with an increasing trend of excessive vibration
__
13
levels on the motor and with a high priority action level. The report
referenced REA 94-0026, which was previously written to improve the fan
motor base attachment. The fan housing is not stiff enough to dampen
the belt vibrations, and a contributing factor may be a mismatch between
the adjustable dual groove sheave and the non-adjustable double wide
powerband belt, which drives the fan. The inspector reviewed the Plant
Equipment Condition Monitoring Program report dated October 15, 1995.
That report also indicated that AHF-8A had excessive vibration levels
but with a low priority action level.
On July 17, 1996, the inspector questioned the licensee regarding the
operable status of AHF-8A. This safety related component has been
operating with known excessive vibration levels since 1994 and the
monitoring data shows an increasing trend of vibration levels.
Licensee procedure CP-150, Identifying and Processing Operability
Concerns, Revision 1, dated May 7, 1996, paragraph 4.1.3 states in part
that the discovery of degraded conditions of components, where
performance is called into question, requires an operability
determination. CP-150, paragraph 4.2, Phase 2: Evaluation, states in
part that the shift supervisor on duty (SS00) evaluates the degraded ;
condition for immediate disposition. If the component is important to
safety the SS0D makes an immediate disposition of either Operable,
Inoperable, or Complex Requiring Further Review. If the component
requires further review, the SSOD is to initiate an Operability Concern
Resolution (OCR). The 0CR is, among other requirements, to contain the
applicable Problem Report number and an immediate disposition.
10 CFR 50, Appendix B, Criterion XVI, Corrective Actions, requires that
measures be established to assure that conditions adverse to quality,
such as failures, malfunctions, deficiencies, deviations, defective
material and equipment, and nonconformances are promptly identified and
corrected.
The failure of the licensee to initiate prompt corrective actions to
address the July 12, 1996 identification of an increasing trend in
excessive vibration on the spent fuel pump cooling fan motor, which was
originally identified in 1994, is first of two examples of a violation.
This violation will be tracked as the first example of VIO 50-302/96-08-
01, Failure to take timely corrective actions.
The system engineer put together an action plan for AHF-8A as follows:
Description of Problem
Vibration levels on the fan motor were first identified as high in 1992
through the Plant Equipment Condition Monitoring Program, and again
early in 1994 through REA 94-0026. The motor subsequently burned up in
May 1994 and was replaced. Vibrations have since increased to the
present level of about 2"/sec., which is extremely rough. Contributing
factors may include a mismatch between the adjustable dual groove sheave
and the non-adjustable double wide powerband belt which drives the fan.
14
Another factor seems to be insufficient stiffness of the sheet metal
housing upon which the motor base is mounted.
Proposed Resolution
1. Implement WR318701 to troubleshoot high vibration problem via MP-
531. Include correct size fixed motor sheave (pitch diameter must
provide desired fan RPM of approximately 1111) to replace original
adjustable sheave; determine whether existing dual powerband belt
is acceptable or whether two single belts should be used. This
may require a review of FIMIS documentation to determine how this
mismatch (if it is) may have occurred.
2. If Step 1 improves the overall vibrational characteristics, the
Rapid Response Team will take steps to make a permanent sheave /
belt change via PEERE, CGWR or MAR. It must be remembered that
i
this cooling unit is Safety Related. 1
3. If, upon installation of a correct sheave / belt configuration,
vibration continues to be amplified by flexing of the mounting
surface, stiffening of the housing will be pursued. REA 96-0727
is in place to begin this modification process.
On July 19, 1996, PR 96-0239, AHF-8A High Vibration, was initiated. The
SS0D dispositioned the AHF-8A as Conditionally Operable /Potentially l
Inoperable with a due date for 0CR AH-96-AHF-8A of September 19, 1996.
No corrective actions had been initiated at the time this report period
ended.
c. Conclusions
The Plant Equipment Condition Monitoring report is very comprehensive,
and is an excellent summary of the status of plant equipment. One
violation was identified for a failure of the licensee to initiate
prompt corrective actions.

- In February 1995 an audit of the make up system disclosed numerous
, problems with the system (see IR 95-08 and IR 95-18). A Corrective
!
Action Plan (CAP) was documented in PR 95-0041. In June 1996 a follow-
up review, performed by quality assessments, was performed to verify the
- status of the corrective action plan.
i The auditor reviewed the corrective actions for CAP item 1 and found
- that the item was partially completed with a request from engineering to
open a CAP item to track additional engineering review of discrepancies
identified during subsequent piping walkdowns. CAP. item 3 was completed
with a request by. engineering to add two additional CAP items to develop-
, a DCN to modify the support drawings for MUH-518 and MUH-519 and to t
l' track completion of the work requests written to verify torque on-anchor
l bolts to MUH-807 and MUH-819. To address CAP item 5, systems engineers
-
initiated 19 work requests to correct deficient conditions identified in
. the original audit. This CAP item was closed, based on.the issuance of
j. the WRs.
. .
The auditor's review revealed that the tracking system for prs,
PRSTATUS, showed all CAP items completed for PR 95-0041, with no
. additional CAP items added. One of the 19 WRs written had been -
! completed. The other 18 WRs had not been planned. The failure to
, create additional steps in PRSTATUS to document the additional CAP items
'
or track the implementation of the CAP items, such as planning and
performing work activities, resulted in failure to complete.these
actions in a timely manner. Since engineering relied on PRSTATUS to
drive the activities committed to in the additional CAP items, these
additional corrective actions were not completed.
10 CFR 50, Appendix B, Criterion XVI, Corrective Action, requires that
measures be established to assure that conditions adverse to quality,
such as failures, malfunctions, deficiencies, deviations, defective
material and equipment, and nonconformances are promptly identified and
corrected. The failure of the licensee to take prompt and adequate
corrective actions to correct deficiencies identified in February 1995
during a make-up system audit is the second example of a violation, VIO
50-302/96-08-01, Failure to take timely corrective actions. This also
indicates a weakness in the PR tracking system. '
c. Conclusions
IFI 50-302/95-08-02 is closed. One Violation and one Weakness were
identified.

R2.1 Calibration of Reactor Buildina Air Sample Line Monitor RM-A6
a. Inspection Scope (84750, 83750)
The inspectors observed the calibration of the gaseous detector channel
on the Reactor Building Air Sample Line Monitor RM-A6 to evaluate the
adequacy of the licensee's process and procedures,
b. Observations and Findings
The licensee utilized CH-232, " Atmospheric Radiation Monitoring System
Calibration Procedure, Revision 30, dated August 6, 1996, for the
calibration of plant atmospheric monitors. The procedure was utilized
to calibrate all of the atmospheric monitors and was somewhat cumbersome
to use, in that it required the user to skip portions of the procedure
not applicable to the monitor being calibrated. Additionally, some of
the steps were not specific and could result in inconsistent actions.
For example, the step for connecting the radioactive calibration gas
loop in the observed calibration did not specify the specific connecting
points to the radiation monitor. The calibration gas loop connecting
points were not identified on the radiation monitors. The technicians
performing the calibration spent considerable time looking for the most ,
appropriate connecting points and selected the most direct path to the
detector chamber. The inspectors noted the radioactive gas could have .
been connected at several locations, which could have resulted in some
'
calibration problems if the equipment was not placed in an appropriate
valve alignment. The procedure also did not include sign-offs for valve
alignment verifications. These issues were discussed with licensee
personnel, and the inspectors learned that the licensee was developing
specific procedures for each monitor to make the calibration procedure
more user friendly. However, the inspectors noted that the draft
procedures also did not include valve position. verification sign-offs.
The inspectors discussed the value of the valve position verification
activities with licensee management. The licensee did not indicate
whether valve position verification sign-offs would be included in the
new procedures.
During the observation of calibration activities in the control room,
the inspectors noted numerous (approximately 10) deficiency and work
order tags on the radiation monitoring panel. Most of the radiation
monitoring system was fully operational and most of the monitors with a
deficiency tag remained operable to some extent. Many of the tags were
less than a month old, however, three were four to eight months old. An
assessment of the adequacy of the maintenance activities on the
radiation monitoring system was not made during this inspection.
However, the inspectors discussed the maintenance of the radiation
monitoring equipment in general with licensee management. The licensee
personnel reported that other maintenance activities having a higher
,
17
priority were resulting in the maintenance delays on the radiation
monitoring system. Tb" inspectors acknowledged that there were :
maintenance activities having a higher safety significance, but reported :'
the operability of the plant radiation monitoring equipment was an
important component in detecting adverse plant and radiological
conditions of fission product barriers, which could warrant a higher
.
'
work priority assignment. The licensee management noted the inspector's
concerns, but did not make any specific commitments to revise l
l maintenance priorities for the radiation monitoring system. ;
c. Conclusions
The calibration process was adequate. The technicians performing the !
csH bration appeared to understand the characteristics of the radiation .
monitor being calibrated and the calibration procedure arJ process. The l
calibraticn procedure was properly utilized throughout th calibration
process. Instrument settings were proper considering the instrument's
response during the calibration. The quality controls in the
calibration procedure could be improved by identifying calibration
connecting points for gaseous source loop and inclusion of valve
position verification sign-offs.
The operability of plant radiation monitoring system could be improved
with more timely maintenance of system equipment.

The report indicated that plant operations in 1995 had not resulted in
any significant impact on the environment resulting from radiological
effluents. The inspectors compared the reported radiation measurements
in the 1995 report with those of previous years and did not identify any
adverse trends. The report was complete and met TS requirements.

The quantity of radioactive liquid and gaseous effluents were generally '
l down from the previous year (1994) with the exception of liquid tritium,
l which was slightly higher than reported in the last few years. The
- quantity of radioactive iodine released in gaseous effluents was
l reported as zero. The licensee did not have a refueling outage in 1995
l and as a result did not need to generate and release the additional
l water needed for refueling activities. The licensee also stored i
l additional water to take advantage of radioactive decay prior to its
release. Radioactive gases were also stored for radioactive decay prior
to their release. The licensee appeared to be effectively managing

the areas of fire protection and emergency planning.
l b. Observations and Findinas
l
l No direct audit findings were identified. Seventeen weaknesses were
!
identified, which resulted in the issuance of PCs. Two of the PCs have

protection surveillance procedures, inadequate corrective actions to
address concerns identified in LER 90-002, the failure to transfer fire
'
i protection technical specifications to the fire protection plan per GL 88-12, and failure to take corrective actions for questions on the fire
service tank water volume. The audit team did not consider that any of
these issues met the criteria for issuing a PR. However, the review of

l A total of 17 PCs were identified, which were evaluated by the audit
! team leader for trends or common concerns. The team leader reported
that there were four basic types of issues:
1. There were indications of a weakness at the first and second level
of defense of quality. These represent a deficiency that
originated at the worker level and was not detected during the
i
,
review and approval process.
2. There was the need for more attention to detail when documenting
l or otherwise describing activities.
3. There appeared to be an indication of a weakness in management
- oversight function.
l 4. A weakness was identified in the timely distribution of industry
information specific to emergency planning issues.
!
c. Conclusions
l
) The review of the audit noted that programmatic assessments were made,
j however the assessments were restricted to the specific areas being
l audited. The licensee appears to be attempting to improve their audits
to include programmatic assessments, but the assessments produced to
date are limited in scope.
A weakness was identified in that a Quality Assurance audit failed to
