INSPECTION EXECUTIVE SU584ARY
Operations
The plant operated at 98 percent power for the majority of the inspection period.
On February
17, 1994, loss of offsite power circuit 751 caused a spurious turbine runback.
By coincidence,
the "A" EDG was operating in parallel with circuit 751 at the time.
Although this prevented
the associated
480-volt safeguard
buses from being deenergized,
the resultant undervoltage
transient caused a momentary turbine runback.
Reactor power was subsequently reduced to less
than 90 percent,
as required by technical specifications, while core axial flux distribution was
stabilized. Full power operation was resumed later that day. Operator response to the transient
was prompt and in accordance with procedure.
Actions were well-focused on establishing and
maintaining plant stability.
On March 4, 1994, the plant was shut down to commence the scheduled annual refueling outage.
At the close of the inspection period, the reactor was in refueling shutdown mode, with reactor
disassembly in progress in preparation for full core offload to support extensive service water,
component cooling water, and residual heat removal system maintenance.
Maintenance
Corrective maintenance on spent fuel pool service water system components
was well planned
to optimize plant safety for a complete core off-load. Diagnostic testing on the Turbine Driven
Pump was effectively carried out to identify and evaluate off-normal
operating parameters.
Engineering
On February
15,
1994, the licensee
determined
that the two manual containment isolation
pushbuttons had not been periodically tested as required by technical specifications.
The licensee
requested,
and was granted, enforcement discretion to defer testing until after shutdown for the
refueling outage.
In January,
1994, the licensee determined
that two containment pressure
instruments had been inoperable since June 1992 due to blockage of the common sensing line
that connects the associated
pressure transmitters with containment;
as a result, the reliability
of automatic
initiation of certain
safety
features
was
degraded.
These
two conditions
demonstrated
that testing was not being appropriately performed, and constituted a violation of
10 CFR 50, Appendix B, Criterion XI, "Test Control."
Executive Summary
Plant Support
On March 1, 1994, while purging the pressurizer to the volume control tank, valve seat leakage
in the post accident sampling system resulted in minor radioactive contamination of water in the
condensate
storage tanks; the health physics technician who discovered
the problem was also
slightly contaminated.
Licensee
response
to this minor radiological event was prompt and
comprehensive.
At the close of the inspection period, a root cause analysis of this event was
in progress.
Safety Assessment/Quality Verification
In a meeting ofthe Nuclear Safety Auditand Review Committee, topics were candidly discussed
and were presented with sufficient detail for board members to assess
the safety significance of
the agenda issues.

OPERATIONS (71707)
1.1
Operational Experiences
At the beginning of the inspection period, the plant was operating at full power (98 percent).
On February
17, 1994, a voltage transient on one of the two offsite electrical power supply
circuits resulted in a fivepercent power reduction due to momentary, transient-induced actuation
of the turbine runback functions.
Operators
subsequently
reduced power to 89 percent,
as
required by technical specifications, while core axial fluxdistribution was stabilized. Full power
operation was resumed later that day and continued until March 4, 1994, when a controlled
shutdown was performed to commence the scheduled annual refueling outage.
At the close of
the inspection period, the reactor was in refueling shutdown mode, with reactor disassembly in
progress in preparation for full core offload to support extensive service water, compone'nt
cooling water, and residual heat removal system maintenance.
1.2
Control of Operations
Overall, the inspectors
found the R. E. Ginna Nuclear Power plant to be operated
safely.
Control room staffing was as required.
Operators exercised control over access to the control
room.
Shift supervisors
maintained authority over activities and provided detailed turnover
briefings to relief crews.
Operators adhered to approved procedures
and were knowledgeable
of off-normal plant conditions.
The inspectors reviewed control room log books for activities
and trends,
observed
recorder
traces for abnormalities,
assessed
compliance with technical
specifications,
and verified equipment availability was consistent with the requirements
for
existing plant conditions.
During normal work hours and on backshifts, accessible
areas of the
plant were toured.
No operational inadequacies or concerns were identified.
1.3
Spurious
Actuation of Automatic Reactor
Protection
System
Due To Offsite
Electrical Transient
Offsite electrical power for the Ginna plant is provided by two independent 34.5 kilovoltsupply
lines, designated
circuits 751 and 767.
Each circuit supplies one of the two station auxiliary
transformers,
12A and 12B. Along with normal site loads,, these transformers each supply two
safety grade (1E) 480 volt electrical buses.
Two emergency diesel generators
(EDGs) serve as
backup 1E power sources for the auxiliary transformers.
The 1E electrical buses are safety
significant in that they supply power to reactor
safety/accident
mitigation equipment
and
instrumentation.
On February 17, 1994, operators were conducting a monthly performance test of the "A"EDG,
with the diesel loaded to 2000 KW. Since normally operating plant equipment does not provide
this much load, the EDG was being operated in parallel with circuit 751,
This electrical
alignment is specified by the performance test and allows operators
to establish the required
EDG loading by backfeeding power through circuit 751.
Concurrent with the EDG testing, a mechanical problem had developed with one of the power
distribution breakers at the offsite supply station (station 204) that supplies power forcircuit 751.
At about 2:20 PM, offsite power control initiated switching operations to isolate the affected
circuit breaker.
During this operation, malfunction of a bank of automatic close-in capacitors
produced a loss of the circuit 751 supply bus.
Since the "A"EDG was coincidentally operating
in parallel with circuit 751, it assumed all of the electrical load upon loss of the normal power
supply. This large increase in load caused the EDG voltage to drop below the undervoltage trip
setpoint of the two 1E bus normal supply breakers.
These breakers opened, thus isolating the
1E buses
(buses
14 and 18) from circuit 751, with power continuing to be supplied to these
buses by the "A" EDG.
Bus 14 supplies normal power to two of the four instrument buses which power one channel of
the reactor
protection
system.
One of these
two instrument
buses
(bus "A") receives
auctioneered power from the 125-volt DC 1E electrical distribution system, such that degradation
or loss of a single power supply will not affect power at the instrument bus.
The other
instrument bus (bus "B") is powered only by bus 14.
Therefore, while the "A" EDG was
carrying circuit 751, the degraded voltage was translated to instrument bus "B". Voltage was
sufficiently low to trip reactor protection system channel "B"protective function bistables.
Since
the reactor protection
system
turbine runback
functions
(overpower
and overtemperature
temperature difference) require only one signal to satisfy the system logic, a turbine runback
occurred during the approximately four seconds of degraded voltage operation.
The automatic turbine runback decreased
plant power to approximately 93 percent.
Although
this was a relatively small power reduction, a xenon buildup complicated the operators'fforts
to maintain allowable core flux distribution. Operators were not successful at maintaining axial
flux difference within the target band, and consequently initiated a further reduction in power
to less than 90 percent,
as required by technical specification 3.10.2.9.
The power reduction
was halted at 89 percent and axial flux difference was stabilized within the target band.
Stable offsite power was restored to circuit 751 within two minutes of the transient.
After
discussion with the load dispatcher,
operators transferred the affected 1E electrical buses back
to circuit 751 and shut down the "A"EDG. Reactor power was slowly escalated,
due to end-of-
cycle core physics constraints, with fullpower operation being achieved at 10:10 PM, February
17, 1994.
The inspector arrived at the control room several minutes after the transient started and observed
good operator
response
to the transient.
Actions per abnormal procedure
(AP)-TURB.2,
"Turbine Load Rejection," were promptly carried out. The Head Control Operator effectively
maintained focus on verifying that the necessary
equipment was operating and that conditions
were stable.
Reactor power was promptly reduced when axial flux difference exceeded
the
target band.
NRC notification was completed as required by 10 CFR 50.72.
Although good procedural
adherence
was observed,
the inspector
questioned
whether the
directions in PT-12.1, "Emergency Diesel Generator 1A," for operation of the EDG voltage
regulator and speed governor, were adequate.
During this test, EDG voltage and speed control
are selected for manual control to facilitate operation of the generator in parallel with the grid.
The procedure contains a precaution to return these controls to automatic ifa safety injection
signal were to occur during conduct of the test.
The basis of this precaution is that the normal
(offsite power) feed breakers
would open in response
to a safety injection signal, and the
generator would become the sole source of power to the associated
safeguard buses.
Although
loss of circuit 751 had produced the same result, operators left the EDG voltage and speed
control in manual,
because
the precaution
was specific to safety injection.
The inspector
discussed this question with the licensee.
The licensee agreed that the precaution for returning
the EDG voltage and speed control to automatic should be extended to a loss of offsite power.
The inspector had no additional concerns on this matter.
1.4
Plant Shutdown For Cycle 24 Refueling Outage
The inspector observed portions of the power reduction and plant shutdown that were conducted
on March 4, 1994 for the Cycle 24 refueling outage.
The inspector observed that the power
reduction was well controlled. Strict procedural adherence and good communications, including
repeat-backs of directed procedural steps, were observed.
Low power operations,
pre-outage
turbine testing, and reactor shutdown were well coordinated.
Management
involvement in
operations was evident during preparations for, and conduct of, turbine testing.
The reactor
shutdown and transition to plant cooldown were conducted deliberately and without incident.
The inspector had no additional concerns in this area.

MAINTENANCE(62703, 61726)
2.1
Preventive/Corrective Maintenance
2.1.1
Routine Observations
The inspector observed portions of maintenance activities to verify that correct parts and tools
were utilized, applicable industry code and technical specification requirements were satisfied,
adequate
measures
were in place to ensure
personnel
safety and prevent damage
to plant
structures, systems, and components, and to ensure that equipment operability was verified upon
completion.
The following maintenance activities were observed:
~
Work Order (WO) 19320990, "Disassemble/Inspect/Replace
V-4622 (Spent fuelpit (SFP)
heat exchanger "A" service water outlet isolation valve), observed February 22, 1994
This is a Crane model 143'lobe valve; as discussed in inspection report 50-
244/93-12, the licensee determined that these valves are susceptible to stem/disc
separation due to failure of the stem/disc lock weld. This maintenance revealed
that the lock weld on this valve had failed, but that there was still full stem/disc
V'
engagement.
Additionally, the seat ring guide (fits around the lower valve stem
to help keep the disc centered) was found to be worn. A non-conformance report
(NCR 94-009) was issued by the Quality Assurance department to document the
deficiencies identified during this maintenance and to authorize interim use until
November 30, 1994.
The inspector considered that conducting this maintenance prior to the refueling
outage was prudent, for the following reasons:
~
Maintenance was coordinated withother service water system maintenance
which required both trains of SFP cooling to be secured
to provide
isolation;
SFP cooling was secured for maintenance when the heat load was low as
possible (approximately 10 months after the last refueling outage and just
prior to the current refueling outage);
With a full core off-load to be performed during the current refueling
outage,
maintenance
performed prior to the outage improved
system
reliability.
The inspector considered that deferral ofvalve replacement
as specified by NCR
94-009 would be of minimal safety significance.
~
"Turbine Driven Auxiliary Feedwater Pump - Repair Outboard Pump
Bearing," observed February 25, 1994
During routine monthly performance testing on February 24, 1994, technicians
noted that the turbine driven auxiliary feedwater
(TDAFW) pump outboard
bearing cartridge temperature increase was greater than expected.
The pump was
declared
pending further investigation.
The following day, after
changing
the bearing oil and inspecting the bearing cartridge,
the pump was
operated for several hours while bearing oil and cartridge temperatures
were
monitored.
Although bearing
cartridge
temperature
was still higher
than
expected,
the long monitored
run time demonstrated
that oil temperature
eventually
stabilized
within the
band
specified
in
the
vendor's
manual.
Additionally, pump vibration was monitored periodically until oil temperature
stabilized, and indicated normal operation.
Based on these results, the TDAFW
pump was declared operable on February 25, 1994.
The inspector considered that this maintenance activity was well executed.
The
inspector considered
that the licensee's
action to declare
the TDAFW pump
operable was adequately supported by the test results.

ENGINEERING (71707)
3.1
Failure to Test Containment Isolation Manual Push Buttons
By letter dated February 15, 1994, RG&E requested
that the NRC staff exercise discretion to
not enforce compliance with the required actions of Technical Specification (TS) Table 4.1.2,
Item No. 9, for testing the manual containment isolation push buttons, because testing at power
could potentially challenge plant engineered
safety features.
RG&E had informed the NRC by
telephone on February 14, 1994, that it had determined that the two control room push buttons,
which can be used by operators to manually actuate the containment isolation system, had not
been
tested
as part of the routine surveillance testing of that system.
On the basis of the
submitted documents,
the NRC staff concluded that postponement of performing this test until
fl
P
6
after the plant is in cold shutdown, beginning March 7, 1994, involves minor safety impact.
Therefore, discretion was exercised to delay testing until the refueling outage and not to enforce
immediate compliance with the requirement ofTS Table 4.1.2, Item No. 9, from 10:00 AMon
February
16,
1994 (the time that the limiting condition for operation for this requirement
expired) to 12:00 AMon March 7, 1994, when the plant would be in cold shutdown and the TS
requirement
would be no longer applicable.
Testing of the manual containment isolation
function willbe performed prior to resuming power operations.
The NRC staff has reviewed relevant plant procedures and supporting documentation, including
Licensee Event Report 94-04, addressing
the functional testing of both containment isolation
push buttons.
Dedicated surveillance testing of this manual function had not been performed as
required by Technical Specifications and as such, represented
failure to implement a testing
program as required by 10 CFR 50, Appendix B, Criterion XI, "Test Control."
Criterion XI
states, "Atest program shall be established to assure that all testing required to demonstrate that
structures,
systems,
and components will perform satisfactorily in service is identified and
performed in accordance with written test procedures which incorporate the requirements
and
acceptance
limits contained in applicable design documents."
Contrary to this requirement,
dedicated
testing of the manual
containment
isolation function was not incorporated
into
procedures
and implemented.
(50-244/94-05-01)
3.2
Containment Pressure Transmitters Inoperable Due to Blockage ofPressure Sensing
Line
As documented in Inspection Report 50-244/94-01, in January
1994, a control room operator
observed that one of the narrow range (0-60psig) containment pressure instruments, PI-947, was
reading slightly lower than the other two, PI-945 and PI-949.
Troubleshooting revealed the cause to be a blockage in the sensing line between containment and
the pressure
transmitter,
PT-947.
The portion of the sensing line within the containment
penetration was found to be made of carbon steel; this was the location of the blockage, which
was later determined to be rust.
Because this sensing line is shared with containment pressure
transmitter PT-948, two channels ofcontainment pressure instrumentation had been inoperable.
Review of computer-archived
data revealed that this condition had existed since June 1992.
The apparent cause ofthe blockage was that water had historically been used as the process fluid
during annual instrument calibrations.
This testing was performed by isolating the detector and
then attaching the pressure
source to a test connection within the detector isolation boundary.
Upon restoration from testing, residual water would drain from the detector, through the sensing
line, and into containment.
Exposure of the horizontal run of carbon steel tubing within the
containment penetration to this runoffwater caused rust, which, after years of service, plugged
the line. Existence of the blockage went undetected for a long period (1) because the scales of
the associated
meters were too large to show significant deflection as a result of normal
containment pressure variations, and (2) because verifying communication through the sensing
line, from the transmitters root valves to its end point inside containment, was not included in
performance testing.
The result of this problem was that it degraded the reliability of automatic initiation of certain
safety features, with the two-out-of-three (2/3) logic being reduced to two-out-of-two (2/2).
Specifically, the 2/3 logic required for a safety injection signal based on a 4 psig containment
pressure would have been reduced to a 2/2 logic with the inoperability ofP-947. However, the
diverse actuation circuitry for the safety injection signal has three additional means of actuation
(steam generator low steam pressure,
pressurizer low pressure,
and manual).
None of these
diverse means was affected by the inoperability of P-947.
The 2/3 logic required for steam line isolation actuation based on a 18 psig containment pressure
was reduced to a 2/2 logic with the inoperability of P-948.
The diverse actuation circuitry for
steam line isolation has three additional means of actuation (high steam flow, high-high steam
flowwith safety injection, and 2/4 low T-average with safety injection, and manual).
None of
these diverse features were affected by the inoperability of P-948.
\\
The 2/3 plus 2/3 logic required for containment spray actuation based on a 28 psig containment
pressure was reduced to a 2/2 plus 2/2 logic with the inoperability ofP-947 and P-948, however,
manual actuation was available ifrequired.
Subsequent
to identifying the plugging, the affected channels were tripped until the line was
cleared and licensee management
tasked the operations and engineering staffs to evaluate the
safety implications and implement corrective actions to preclude a recurrence.
Results of these
efforts are documented in LER 94-02, submitted to the NRC on March 4, 1994.
In reviewing LER 94-02, the inspector identified two shortcomings in the licensee
s scope of
corrective action and safety evaluation.
First, the licensee
failed to address
test program
inadequacies
that resulted in a failure to promptly identify line blockage and inoperable pressure
sensing channels.
This incident is similar in nature to that described in section 3.1 above, in
which containment isolation pushbuttons were not tested, and represented
a second example of
a violation of the requirements of 10 CFR 50, Appendix B, Criterion XI, "Test Control" (see
Detail 3.1).
The second shortcoming was that an evaluation of the effect of the loss of one (circuit 751) of
two offsite power sources
on the remaining operable pressure
channels
was not addressed.
Automatic containment spray initiation could be compromised by a loss ofcircuit 751 in certain
situations
because
such
a loss could temporarily deenergize
safety bus
14 and associated
instrument bus "B", which has no backup power supply. Instrument bus "B" powers one set of
pressure
sensing channels (PI-946 and PI-949).
Therefore, loss of instrument bus "B" could
cause
the loss of an additional two channels of containment pressure
instrumentation.
The
licensee acknowledged this design vulnerability and willaddress this evaluation in a supplement
to LER 94-02.
8
The inspector reviewed the licensee's
immediate corrective actions taken in response
to this
incident including: placing the affected pressure channel relays in the tripped position, clearing
the sensing line, daily trending narrow range containment pressure
indications on the plant
computer, revising the instrument calibration procedure
to use air rather than water as the
process fluid, and scheduling inspection of the remaining containment pressure
sensing lines
during the refueling outage.
The inspectors had no further questions at this time.

PLANT SUPPORT (71707)
4.1
Radiological Controls
4.1.1
Routine Observations
The inspectors periodically confirmed that radiation work permits were effectively implemented,
dosimetry was correctly worn in controlled
areas
and dosimeter
readings
were accurately
recorded, access to high radiation areas was adequately controlled, survey information was kept
current, and postings and labeling were in compliance Lith regulatory requirements.
Through
observations ofongoing activities and discussions with plant personnel, the inspectors concluded
, that the licensee's radiological controls were generally effective.
4.1.2
Post Accident Sampling System Material Condition
On March 1, 1994, operators established
a purge of the pressurizer
steam space to the volume
control tank, through the post-accident sample system (PASS).
The purpose of this purge was
to reduce the hydrogen concentration in the pressurizer in preparation for the refueling outage.
While this purge was in progress,
a health physics (HP) technician prepared to perform a water
flush of the PASS deionized water header.
The PASS is configured
such that these two
operations can be performed simultaneously; however, as preparatio'ns for the flush progressed,
the HP technician observed
steam coming from a flexible hose in the DI water header.
A
portable radiation survey instrument in the area of the steam discharge alarmed, indicating that
the pressurizer was the likely source of the steam.
The HP technician isolated the flexible hose
and then informed the control room operators of the problem.
Venting of the pressurizer
through the PASS was secured.
Extensive radiation and contamination surveys were performed.
The HP technician was found
to be contaminated with short-lived radioactive gases, and was decontaminated.
Radiation levels
in the vicinityof the steam leak were normal.
Some loose surface contamination was detected
on the floor in the area of the leak; the area was roped off, and subsequently
cleaned
and
decontaminated.
Since the deionized water header cross-connects
to several other radiologically
clean water systems, all connecting water systems were sampled for radioactive contamination.
Small concentrations ofradioactive gases and particulates were found in the condensate
storage
tanks.
The concentrations
were so low as to not pose a radiological concern for normal use.
No significant contamination was detected in the remaining deionized water systems associated
with this event.
(

~'
In response to this event, the licensee initiated a root cause analysis investigation.
The affected
portions of the PASS were removed from service, pending results of this investigation and
determination of corrective action. Multiplevalve seat leakage through the ih-inch line was an
apparent contributor to this event.
The inspector examined the material condition of the PASS.
The inspector noted that the existing installation ofthe air operator forvalve AOV-10017 (PASS
sample cooler outlet AOV to PASS liquid and gas sample panel), a valve that is normally shut,
could have allowed for some seat leakage.
This, and several minor material discrepancies,
were
addressed
to the licensee.
The inspector assessed
the licensee's
response
to this radiological event to have been good.
Based on the nature and duration of the discharge,
as well as the measured contamination levels,
the inspector assessed
that the radiological significance of this event was minimal.
At the close of the inspection period, the licensee
s root cause investigation was in progress.
The inspector had no further questions at this time.
4.1.3
ALARAPlanning For Outage
The inspector reviewed
the ALARA planning packages
that will be used to support core
offload/refueling operations and motor operated valve testing during the 1994 outage.
Through
this review, the inspector determined that the licensee has proactively addressed
measures
to
reduce
exposure
to personnel

5.1
Periodic Reports
Periodic reports
submitted by the licensee
pursuant
to Technical Specification 6.9.1 were
reviewed.
Inspectors verified that the reports contained information required by the NRC, that
test
results
and/or
supporting
information were
consistent
with design
predictions,and
performance specifications, and that reported information was accurate.
The following reports
were reviewed:
Monthly Operating Reports for January and February 1994
Semi-annual Radioactive Effluent Release Report (July-December
1993)
No unacceptable
conditions were identified.
5.2
Licensee Event Reports
Licensee Event Reports (LERs) submitted to the NRC were reviewed to determine whether
details were clearly reported,
causes
were properly identified, and corrective actions were
appropriate.
The inspectors also assessed
whether potential safety consequences
were properly
evaluated, generic implications were indicated, events warranted additional onsite follow-up, and
applicable requirements of 10 CFR 50.72 were met.
The following LERs were reviewed (Note:
date indicated is event date):
94-001, Radiation Monitor R-32 (Main Steam Line) Not Properly Calibrated.
R-32
output was one decade low due to a technician's mathematical error.
(January 19, 1994)94-002, Containment Pressure Transmitters PT-947/PT-948 Inoperable Due to a Blocked
Sensing Line (February 2, 1994)
The inspector concluded
that LER 94-001 was accurate,
met regulatory requirements,
and
appropriately identified the root causes.
Shortcomings identified in LER 94-002 are addressed
in section 3.2 of this inspection report.
In response,
the licensee willsubmit a supplement to
LER 94-002.
