Followup on Previously Identified Items
a.
(0 pen) Unresolved Item 285/8624-01:
Failure to maintain training
records in accordance with regulatory requirements.
This unresolved item involved the licensee's failure to maintain a
training records system. Since the issuance of this unresolved item,
the licensee has taken steps to establish a records program, but has
yet to complete the actions.
The NRC inspector discussed the current status of the records system
with the Supervisor Station Training. The supervisor stated that a
contractor with extensive. experience in establishing an auditable
records system was hired in February 1987. This-individual initiated
the development of a new records system.
The new records system will.
be a. computerized system with software specifically developed for
this application. The new system will be fully functional by the end
of 1987.
This item remains open pending the establishment of a' functional
training records system.

b.
(0 pen) Unresolved Item 285/8624-02:
Failure to provide on-the-job
training.
This unresolved item was related to the licensee's failure to provide
licensed operators with the on-the-job training specified in the
licensee's approved training program.
The licensee revised the worksheet used during simulator training.
The worksheet previously used by the licensee was the generic
worksheet issued by Combustion Engineering.
The newly revised
worksheet was specifically developed to include all control
manipulations and plant evolutions required by the licensee's
NRC-approved training program.
Each manipulation and evolution was
provided with an individual sign off to ensure all activities were
completed.
The NRC inspector reviewed the simulator worksheets for selected
reactor operators and senior reactor operators to verify that all
required evolutions and manipulations were performed.
No problems
were noted during the review.
This unresolved item also identified a problem with the licensee not
providing classroom lectures for the evolutions not capable of being
performed at the simulator.
The NRC inspector reviewed records to
verify that classroom training was given for-the loss of instrument
air and the loss of shutdown cooling.
Based on the results of the
review, the licensee did not provide classroom lectures for the loss
of instrument air or shutdown cooling during 1985 and 1986.
This item remains open pending the completion of the appropriate
classroom lectures and the establishment of a program by the licensee
to ensure that a lecture in the loss of instrument air and the loss
of shutdown cooling is provided in each 2 year requalification
training cycle.
c.
(Closed) Open Item 285/8624-06:
Implementation of commitments made
by the licensee to upgrade the licensed-operator requalification
program.
This open item is related to commitments made by the licensee in a
letter dated December 23, 1985, for upgrading the requalification
program. The commitments were made in response to the failure of the
NRC-administered requalification examination by six of eight licensed
operators.
Each of the specific areas addressed by the licensee for
program upgrade are discussed below.
Improved attendance at scheduled requalification training
.
sessions was encouraged by issuance of a management policy in
October 1986.
Licensee personnel stated that the new policy
increased lecture attendance by licensed operators, but
attendance by licensed staff personnel had not changed
,
,
4
significantly.
Licensee personnel also stated that the new rule
change to 10 CFR Part 55 made by the NRC will solve the problem
of attendance as attendance will be mandatory.
The rule change
becomes effective in May 1987.
Lesson plans have been upgraded to reflect the new
.
performance-based training program. The upgraded lesson plans
were being used by classroom instructors and had been provided
to NRC operator licensing personnel.
The licensee issued new qualification manuals to each senior
.
reactor operator. The new manual provided requirements for
completion of specific items during the requalification cycle.
Completion of the items will ensure that each senior operator
reviews the appropriate areas.
3.
Operational Safety Verification
The NRC inspector conducted reviews and observations of selected
activities to verify that facility operations were performed in
conformance with the requirements established under 10 CFR, administrative
procedures, and the TS.
The NRC inspector made several control room
observations to verify the following.
Proper shift staffing and turnover
.
Operator adherence to approved procedures and TS requirements
Operability of reactor protective system and engineered safeguards
.
equipment
Logs, records, recorder traces, annunciators, panel indications, and
switch positions complied with the appropriate requirements
Proper return to service of components
.
Maintenance orders (MO) initiated for equipment in need of
.
maintenance
Appropriate conduct of control room and other licensed operators
Management personnel toured the control room on a regular basis
.
No violations or deviations were identified.
4.
Plant Tours
The NRC inspector conducted plant tours at various times to assess plant
and equipment conditions. The following items were observed during the
tours.

General plant conditions, including operability of standby equipment,
.
were satisfactory.
Equipment was being maintained in proper conditions, without fluid
.
leaks and excessive vibration.
.
Plant housekeeping and cleanliness practices were observed, including
no fire hazards and the control of combustible material.
Performance of work activities was in accordance with approved
.
procedures.
Portable gas cylinders were properly stored to prevent possible
.
missile hazards.
Tag out of equipment was performed properly.
.
,
Management personnel toured the operating spaces on a regular basis.
.
During a plant tour on April 1,1987, the NRC inspector noted that a hose
had been run through the doors to both emergency: diesel generator (EDG)
rooms.
The hose held both doors open. causing.the fire' barriers associated
with the doors to be nonfunctional.
The NRC inspector also noted that a
hose had been run through an opening with a fire guillotine _ curtain that
separated the EDG rooms. With the hose in place, the curtain could not
perform its intended function, causing the fire barrier to be
i
nonfunctional.
In discussions with security personnel, the NRC inspector
determined that the hoses had been run through the EDG doors and the
opening for approximately 2 days. At the time of discovery by the NRC
inspector, personnel were working in the area.
However,- the areas were
a
not continuously manned during the 2-day period.
TS 2.19(7) states, in part, that all penetration fire barriers protecting
safety-related areas shall be functional. With a penetration fire barrier
nonfunctional, within I hour, either establish a continuous fire watch on
j
at least one side of the affected penetration, or verify the- operability
of fire detectors on at least one side of the penetration and establish an
hourly fire watch patrol.
t
'
The licensee implemented the requirements of TS 2.19(7) by issuance of
Procedure S0-0-38, " Fire Watch Duties and Turnover Procedures." This
procedure required that, if an hourly watch patrol is allowed per TS 2.19,
,
'
an FC-1006 form shall be filled out for the duration of the patrol watch
period.
.
The NRC inspector determined that an FC-1006 form (hourly fire watch
patrol log) had not been completed for the nonfunctional barriers in the
EDG rooms. Without completion of the form, no objective evidence existed
to indicate that an hourly fire watch had been established or that the-

fire detectors.on one side of the fire barrier had been checked for
operability. The failure to provide an hourly fire watch in accordance
with TS 2.19(7) is an apparent violation'.
(285/8710-01)
Upon notification by the NRC inspector, the fire barriers were restored to
a functional. status.
In followup on this apparent problem, the NRC
inspector noted that the fire-door lights for the.EDG room doors on the
central alarm station (CAS) were not operating. The. security guard
stationed on the CAS uses the lights as an indication that the doors are
open. Prior to an hour elapsing with the lights lit, the security guard
notifies the shift supervisor that an hourly fire watch patrol is.
required. The shift supervisor will then verify operability of the fire
'
detectors on one side of the barrier and establish a roving fire watch by
i
completion of the FC-1006 form.
During plant tours, the following items were.also identified.

The state of Nebraska certification of the annual inspection for the
.
personnel elevator-in the administrative building expired on April 1,
1987. Upon notification by the NRC inspector, the licensee had the
elevator recertified.
One end of the handrail in the stairwell adjacent to the auxiliary
.
building elevator had come loose due to the fastener falling out of
the wall. The loose handrail posed a personnel safety hazard for
anyone using the stairwell. The licensee was notified of this item
on April 20, 1987; however, the handrail had not been repaired prior
to the end of this inspection period.
Fire Door 989-11 was found not to function properly. On two
.
occasions during the month, the door was found unlatched. Upon
notification by the NRC inspector, the door was repaired. The-
licensee continued to experience difficulty in maintaining fire doors
as evidenced by the repeated identification of nonworking fire doors
during previous monthly inspections.
5.
Safety-Related System Walkdown
The NRC -inspector walked down accessible portions of 'the following
safety-related system to verify system operability. Operability was
determined by verification of selected valve and switch positions. The
,
system was walked down using the drawing and procedure noted.
Fire protection system (Procedure OI-FP-6, Revision 50, and
.
Drawing M-266, Revision 35)
During the walkdown, no problems were noted between the drawing,
procedure, and plant as-built conditions for the selected areas checked.

Deficiencies identified during the testing were properly reviewed and
.
resolved by appropriate management personnel.
The NRC inspector observed and/or reviewed the documentation for the
following surveillance test activities. The procedures used for the test
activities are noted in parenthesis.
Mechanical penetration seals leak rate testing (ST-CONT-2-F.6)
.
Monthly check of station batteries (ST-DC-1-F.1)
.
Remotely operated ventilation damper check (ST-VA-1-F.3)
.
Inservice inspection of raw water valves (ST-ISI-RW-F.1)
.
Fire protection system test and inspection (ST-FP-1-F.1)
Control room ventilation filter circuit operation (ST-CRV-1-F.1)
.
Phosphate basket chemical sampling (ST-CHEM-1-F.3)
.
Containment isolation valves leak rate testing (ST-CONT-3-F.1).
During review of the completed copy of Surveillance Test ST-CRV-1,
" Control Room Ventilation Filter Circuit Operation," the NRC inspector
noted that the test had not been completed when scheduled on April 2,
1987.
The test is required to be performed by TS 3.2, Table 3-5,
Item 10.a.3.9, to verify the operation of ventilation dampers for the
design basis accident mode. A note made by the control room operator on
the completed test copy stated that the testing was_not performed because
the plant was in a limiting condition for operation (LCO) due to one
channel of the toxic gas monitors being out of service for calibration.
When in the LCO, operation of the ventilation system in the filtered
makeup mode is prohibited. A review of the station log indicated that the
LCO was exited at 10:15 a.m. on April 2, 1987.
It appeared that the test-
was signed off prematurely as the test could have been performed later in
the day.
During a subsequent review of completed surveillance tests by the
Supervisor Operations, it was noted by the supervisor _that the test had
not been performed. The supervisor rescheduled the test and the test was
completed on April 17, 1987. By performing the test in April, the
TS required frequency of the surveillance test was not exceeded.

On January 13, 1987, the licensee issued Licensee Event Report (LER) 86-05
that described an event where the surveillance test frequency for
exercising the control element assemblies every.2 weeks was exceeded. The
frequency was exceeded due to plant conditions prohibiting performance of
the test. . The licensee stated in the LER that anytime a surveillance test
can not be performed when scheduled, an entry would be made on the shift
turnover log. This commitment was made to ensure the oncoming shifts were
. aware of the need to perform any surveillance that was not performed due
to plant conditions.
Under the licensee's system of administrative controls, a shift turnover
log was not required to be kept whenever the reactor coolant system
temperature was less.than 300 degrees.
The plant was in the cold shutdown
mode on April 2,1987.
For this reason, when ST-CRV-1 was not performed
as scheduled, no entry was made on the shift turnover log. The failure to
list surveillance test not performed when scheduled on the shift turnover
log is an apparent deviation from a commitment made to the NRC in
LER 86-05.
(285/8710-02)
On April 29, 1978 the licensee changed the administrative controls that
defined the use of the shift turnover log.
The new controls stated that
the. log shall be used at all times.
The NRC inspector verified that
,
operations personnel had commenced using the shift turnover log and were
entering surveillance tests'on the log when not performed as scheduled.
i -
During review of the completed copy of surveillance test
procedure ST-CHEM-2-F.3, " Phosphate Basket Chemical Sampling Inspection,"
the NRC inspector noted that the test had not been performed in accordance
,
with the requirements of TS 3.6(2) d.(ii). Testing of the trisodium.
phosphate dodecahydrate (TSP) is performed during the refueling outage to
verify that the TSP stored in the containment is chemically capable of
raising the pH of the boric acid solution used in the containment' spray
system to a minimum of 7.0.
The boric acid solution is stored in the
.
safety injection and refueling water tank and is maintained at the
refueling boron concentration. The pH of the slightly acidic boric acid
!
I
solution is raised to a pH of 7.0 to minimize the effects of chloride
stress corrosion on exposed materials in containment when the solution is
reused during recirculation operations.
ST-CHEM-2-F.3 was performed to verify that the TSP stored in containment
!
was chemically capable of performing its intended safety function by
requiring that a specified amount of TSP be dissolved in a given volume of.
boric acid solution at the refueling boron concentration. The
surveillance test required that the resultant pH of the TSP / boric acid
mixture be a minimum of 7.0.
The test procedure did not specify the value
of the refueling boron concentration.
On March 9,1987, the NRC issued TS Amendment 103 Sdlich' raised the
required refueling boron concentration from 1700 parts per million (ppm)
to 1800 ppm. The effective date of the TS amendment was March 9, 1987.
The licensee completed the surveillance test on March 19,11987. During

performance of the test, the chemistry technician used a refueling boron
'
concentration of 1755 ppm and obtained a ^ resultant-pH of :7.08.
At the
j
time the test was performed,_.the technician did not realize that the value
of the refueling boron concentration had been changed by a TS amendment.
,
'
The NRC inspector reviewed the circumstances related to the-error made
during performance of the test to determine whether the. information . .
provided by the TS amendment was not available to the technician or the
technician failed to consult the appropriate documentation.during
performance of the test. The inspector had not completed this review by
the end of this inspection period. This. item remains unresolved pending
completion of the review by the NRC inspector.
(285/8710-03)
Upon notification by the NRC inspector, the . licensee stated that another
test would be performed to verify that the TSP was capable of. performing
.
t
its safety function. The licensee stated that the test would be-performed
at a refueling boric acid concentration of at least_1800 ppm.
The-
'
licensee had not completed the retest at the end of this inspection
period. This item remains unresolved pending completion of the' test and a 9
<
review of the test results by the NRC inspector.- (285/8710-04)
During review of the TS and the updated safety analysis report (USAR), the
NRC inspector noted an apparent discrepancy between the amount of TSP-
required to be stored in containment by the TS and the amount required by
>
the USAR. The TS states that the amount of TSP required is 40 cubic feet
.
(approximately 1500 pounds); however, the USAR states that 3000 pounds qf
!
TSP is required.
The licensee could not explain the. apparent discrepancy
~
between the values stated in the two documents. .This_ discrepancy remaias
,
an unresolved item pending determination by the licensee of the correct

Radiological Protection Observations
The NRC inspector verified that selected activities of the licensee's
radiological protection program were implemented in conformance with the
facility policies and procedures and in compliance with regulatory
requirements. The activities listed below were observed and/or reviewed.
Health physics (HP) supervisory personnel conducted plant tours to
.
check on activities in progress.
Radiation work permits contained the appropriate information to
.
ensure work was performed in a safe and controlled manner.
Personnel in radiation controlled areas (RCA) were wearing the
.
required personnel monitoring equipment and protective clothing.
.
Radiation and/or contaminated areas were properly posted and
controlled based on the activity levels within the area.
Personnel properly frisked prior to exiting an RCA.
.
Personnel were aware of and actively participated in the as low as
.
reasonable achievable (ALARA) program.
The licensee was meeting the ALARA goals for personnel exposure.
.
1
The plant has been in a refueling shutdown for approximately two months.
For this reason, the licensee has expended approximately 250 man-rem of
tne 345 man-rem goal established for 1987. The refueling outage will last
approximately one additional month.
Licensee management stated that
meeting the man-rem goal for 1987 was still achievable, as the exposure
,
levels will decrease significantly when the plant returns to operation.
,.
The licensee instituted an ALARA concerns program where any person working
onsite can submit concerns to the ALARA committee.
Each concern is
reviewed by the committee and an answer provided to the individual
submitting the concern.

' determined that no SOR Model.102 or 103 differential pressure switches-
were installed or planned to be installed in any systems subject to the
requirements of-the TS.
The NRC inspector performed a random, independent check o'f selected
switches to verify that the switches were not 50R Model 102 or 103.
During this review, no problems were noted.
IE Bulletin 86-03, " Potential Failure of Multiple ECCS Pumps Due to' Single -
Failure of Air-Operated' Valve in Minimum Flow Recirculation Line," was '
issued to alert licensees of the possibility of a common-cause failure' of-
emergency core cooling system (ECCS) pumps due 'to failure of the
air-operated valve ~1n the. minimum recirculation flow line.
Potential
problems had been noted at other plants due to the recirculation valv'e

On November 13, 1986, the licensee provided a. response to IE
Bulletin 86-03 that stated the air-operated valves used in-the
-recirculation line for the ECCS pumps were not subject to single-failure.
problems. .The results of the licensee's investigation indicated that the
recirculation valves failed open on:a' loss of electrical power or air
pressure.
The NRC inspector reviewed the operat' ion of the-valves in the ECCS pumps

No violations or deviations were identified.
12. Refueling Activities
The NRC inspector reviewed / observed various activities performed during
refueling to verify the activities were performed in accordance with the
TS and approved licensee procedures.
The activities observed / reviewed
included the following.
Proper shift staffing by qualified individuals was provided.
.
.
Containment integrity was established and maintained.
.
Good housekeeping and loose object control on the refueling bridge
.
was maintained.
Fuel handling operations were performed in accordance with approved
licensee procedures.
The proper refueling cavity water level was maintained.
.
Chemistry sampling was performed at the frequency specified in the
.
TS.
During observation / review of the above activities, a problems was noted by.
the NRC inspector concerning containment integrity. 'During a tourfof the
control room on April 9, 1987, the NRC inspector noted that the-automatic
isolation valves'(HCV-438A and HCV-438C) inside containment for component
cooling water (CCW) supply and return for the' reactor coolant pumps were
inoperable. The valve control fuses-had been removed for maintenance.and
the valves were in the open position.
The plant was in refueling
operations, but the automatic isolation valves (HCV-4388 and HCV-4380)
outside containment were not-closed.
TS 2.8 states, in part, that the following conditions shall be satisfied
during any refueling operations. TS 2.8(1) states, in part, that all
automatic containment isolation valves shall-be operable or at least one
valve in each line shall be' closed.
_
_
_
_
C
o..
.
15~
The licensee failed to meet the requirements of-TS 2.8(1) in that the CCW
automatic isolation Valves HCV-438A and HCV-438C were-inoperable, and
Valves HCV-438B and HCV-438D in each CCW line were not closed. This is an.
apparent violation.
(285/8710-06)
.
Upon notification'of the apparent" problem by the NRC inspector, control'
room personnel shut Valves HCV-438B and HCV-4380.
During followup by the
NRC inspector, it was determined that Valves HCV-4838 and HCV-438D had
been danger tagged in the closed position on March 13, 1987.
However,
during performance of a surveillance test on April 8,~1987, power was-
momentarily lost on each DC bus. This loss of DC power caused
,
Valves HCV-4388 and HCV-4380 to automatically open. When power was
^
restored to the DC bus,'the valves did not automatically reclose. The
actions of the valves on loss of DC power conformed to the engineering-
design of the valve circuitry. Subsequent to the performance of the
surveillance test on the DC bus, control room personnel failed to note
that Valves HCV-438B and HCV-438D remained open. The valves were
subsequently found open by the NRC inspector.
During the previous inspection period, the licensee performed an off load
of all fuel assemblies.
The off load was performed to check for leaking
fuel assemblies. During this inspection period, the licensee completed
the testing of the fuel assemblies.
The testing indicated that two of the
fuel assemblies were leaking. The licensee provided a like-for-like
replacement of the leaking assemblies.
The assemblies were returned to
the vessel.
The NRC inspector observed transfer of the assemblies and
noted no other problems associated with the movement or handling of the
fuel.
13. Containment Local Leak Rate Testing
The NRC inspector performed this inspection -to verify, through observation
and records review, that the local leak rate test program for testing of
the containment isolation valves was being performed'in accordance with TS
requirements.
The NRC inspector observed / reviewed the following' items.
-
All containment isolation valves listed in the TS were tested in
.
accordance with the licensee's approved procedure.
l
Procedure ST-CONT-3, " Containment Isolation Valves Leakage Rate Test
.
- Type C," provided the appropriate instructions for testing of
!'
The test equipment used was in current calibration.
.
i
The pressure used for testing conformed to the pressure specified in
'.
.
the TS.
l
Repairs were initiated for any penetrations discovered-to be leaking.

Action was taken to verify that.the maximum allowable leakage rate
.
.
was not exceeded upon discovery of a leaking penetration.
.During. review of Procedure ST-CONT-3, the NRC inspector noted that the
,
procedure failed to provide adequate instructions for the performance of.
,
leak rate testing of the containment isolation valves. The. instructions
'
were provided by using a one-line, test equipment connection diagram and
.providing a valve lineup on each diagram. The specific examples of the
inadequate instructions are provided below.
'
The diagram for testing Valves HCV-500A and HCV-5008 (Penetration
.
M-20) indicated that the pressure source used for testing be
connected on the upstream side of Valve HCV-500B,-instead of
connecting the pressure source between the valves. By performing the
test as stated.in.the-instructions, the actual leak rate of the-
valves could not be. determined.
~
The valve lineup shown on the diagram for testing Valves HCV-506A and
.
HCV-506B (Penetration M-8) was inadequate in that a vent path on each
side of the nonpressurized side of the valves was not established.
Without a vent path, the actual leakage rate through the valves could
.
not be determined.
'
Instructions =for testing of Valve HCV-2983 (Penetration M-22) did not
.
ensure that the piping on the side of the valve not pressurized by
the test wasn't pressurized during testing.
If the pressure across
the. valve became equalized,'the test would not indicate the actual
valve leakige rate.
The valve lineup on the diagram for 1esting Valves HCV-2604A and
.
HCV-2604B (Penetration M-43) stated Valve VD-374 should be opened for
<
the test; however, VD-374 did not exist.
i
'
The valve lineup on the diagram for testing Valve HCV-746B was
.
incomplete as Valve VA-262 was not included.
.
The instructions established by Procedure ST-CONT-3 were inadequate in
that the procedure did not provide instructions that would ensure that;the
i
actual leak rate of the valves was determined.
,
During review by the NRC inspector,. it was established that the testing
'
for the valves listed above was not performed in accordance with the
instructions provided in the procedure.
The technicians realized that the-
instructions were not accurate-and established an alternate method of
testing the valves in lieu of following the-instructions.
i
TS 5.8.1 states, in part, that written procedures shall be established,
implemented, and maintained that meet the minimum requirements of
j
Regulatory' Guide 1.33.

Section 8.b of Regulatory Guide l.33 states, in part, that containment
local leak detection tests should be covered by written procedures.
Contrary to the above, the licensee failed to properly establish a
procedure for local leak detection tests in that-Procedure ST-CONT-3 did
not. provide adequate instructions for performance of-the local leak rate
testing.
In addition, the licensee failed to properly implement the
instructions for local leak detection in that the . instructions provided in
Procedure ST-CONT-3 were.not followed by the technicians performing the.
work. This is an apparent violation.
(285/8710-07)
In review of-the performance of leak rate tests, the NRC inspector
determined that the licensee performed the leak rate testing during the
1985 refueling outage using the same instructions-in Procedure ST-CONT-3.
No action had been taken by the licensee to correct the. inadequate
instructions at that time or during the current refueling outage. The
licensee has not established a policy or procedure that requires procedure
adherence.
In response to this violation, the licensee should address-the
lack of having a procedure that addresses the need for verbatim compliance
when performing safety-related activities.
2'
Upon notification by the NRC inspector of the inadequate instructions in
Procedure ST-CONT-3, the licensee issued a procedure change. The basis of.
j
the-changes made to the procedure was to reflect how the tests were
actually performed by the technicians.
The licensee had not cumpleted the Type B and C tests for all penetrations
at the end of this inspection period.
For this reason, this portion of
!
this inspection will be continued into the next inspection p'eriod.

Licensed Operator Initial Training
The NRC inspector reviewed the initial licensed operator training program
to verify that the program being implemented by the licensee complied with
the licensee's NRC-approved training-program and 10 CFR Part 55.
During
~
performance of this review, the NRC inspector verified that the following-
program elements were properly implemented by the licensee.-
Required lectures by the licensee's NRC-approved training program
.
were attended.
Simulator training center certification of training was completed.
.
Required time onshift was performed.
.
Records were maintained by the training department to document
.
participation by each licensing candidate in the above activities.
No violations or deviations were identified.
This portion of the
inspection has been completed.

Licensed Operator Requalification Program
The NRC inspector reviewed the licensed operator requalification program
to verify that the program being. implemented by the licensee complied with
the licensee's NRC-approved training program and 10 CFR Part 55. During
performance of this review, the NRC inspector verified that the following
program elements were implemented by the licensee.
Preplanned lectures required by the licensee's NRC-approved training
.
program were given to the operating staff in each 2 year
requalification program.
Documentation was available to indicate that staff supervision
.
personnel (licensed individuals not assigned to an operations crew)
reviewed facility design changes, procedure changes, facility license
changes, and abnormal and emergency operating procedures.
All licensed individuals who failed the annual written examination
were placed in an accelerated requalification program.
All licensed individuals who scored low in any particular category
were required to attend appropriate lectures.
All licensed individuals received on-the-job training as specified by
the licensee's NRC-approved training program.
Each licensed operator completed an annual requalification
.
examination prepared by the licensee.
Records were maintained by the training department to document
participation by each licensed operator in the above activities.
The NRC inspector also reviewed the training program presently used by the x
licensee against the training program originally appewed by the NRC.
This review was performed to verify that revisions made by the licensee to
the NRC-approved program had not lessened the requirements of the program.
No instances were noted where the program had been degraded.
During review of the results of the annual written examinations given in
1986, the NRC inspector noted that a senior reactor operator (SRO) had
failed to pass the examination given on December 11, 1986. The SR0's
overall score on the examination was 73.9 percent.
Due to the low score,
the SRO should have been placed in accelerated requalification training,
but was not. At the time of the examination, the SR0 was in training for
preparation to take an NRC-administered written and walk-through
examinations.
Licensee personnel stated that the training given in
preparation for the NRC-administered examination was equivalent to-the
training the SRO would have received in the accelerated training program.
In March 1987, the SRO was given a walk-through examination by an NRC
licensing examiner and successfully passed the examination. Shortly
e...
19
thereafter, the SR0 was returned to the operating shift in the capacity of
a licensed operator.
The licensee had not given the SR0 another written
examination prior to returning the SRO to licensed-operator duties. The
SR0 was onshift for approximately 2 weeks before being removed and placed
back in a training status. The SR0 was returned to training to prepare
for the NRC written examination to be given in June 1987.
Section 4.a of Appendix A to 10 CFR Part 55 requires, in part, that the
requalification program include an annual written examination which
determine areas in which retraining is needed to upgrade licensed senior
operator knowledge.
'
Section 9.a. of the licensee's NRC-approved training program (Appendix B
of the licensee's Training Manual) requires, in part, that an annual
written examination be conducted and failure of this examination (overall
grade of less than 80 percent) requires the individual be placed in an
accelerated requalification program. The NRC-approved training program
also requires that an individual failing the annual written examination be
removed from licensed duties during the period of accelerated training.
The failure of the licensee to remove the SRO from licensed duties during
the period of training is a potential violation which will be considered
an unresolved item.
(285/8710-08)
Licensee personnel stated in discussions regarding this unresolved item
that the SRO should not have been allowed to resume licensed duties until
the SRO had been reexamined to determine that the SR0 had an adequate
knowledge level.
Licensee personnel also stated that the SR0 was allowed
to return to licensed duties due to an oversight on their part.
The NRC inspector reviewed the licensee's actions related to' corrective
measures taken on the unresolved items identified in the previous review
of the requalification program performed by the NRC in August 1986. The
results of the review is provided in paragraph 2 of this inspection
report.
The NRC inspector did not complete the inspection in this area during this
inspection period.
This portion of this inspection will be continued into
the next inspection period.
No violations or deviations were identified.
16. Unresolved Items
An unresolved item is a matter about which more information is required in
order to determine whether it is acceptable, a violation, or a deviation.

17. Meetings
During this inspection period, two meetings were held with licensee
personnel. On April 6, 1987, a meeting was held in the Region IV office
at the licensee's request to discuss plant design basis documentation.
Attendees included licensee representatives, Region IV management
personnel, the NRR project manager, the senior resident inspector, and a
representative of IE Headquarters.
The second meeting was held on April 15, 1987, at the licensee's emergency
offsite facility to discuss core damage estimates. Attendees at the
meeting included licensee representatives, Region IV management, the
Region IV emergency planning specialist, the senior resident inspector,
and representatives from the states of Iowa and Nebraska.
