EXECUTIVE SUMMARY
LaSalle County Station, Units 1 and 2
NRC Inspection Report No. 50 373/g7020(DRP); 50-374/g7020(DRP)
This inspection i sort included aspects of licensee operations, maintenance, engineering and
plant support. Ti. toport covers a six week period of Inspection conducted by the resident staff,
Operatigni
+ The inspectors identified a violation involving the failure of operations personnel to ensure
that all operability evaluations remained on file in the control room. The unavailability of
one operability evaluation resulted in an unnecessary entry into a Technical Specification
limiting condition for operation action statement. Engirieering personnel were removing
the evaluations in anticipation of a procedure change that had not yet been implemented.
Engineering personnel demonstrated a lack of questioning attitude regarding the
operationalimpact of removing the operability evaluations. (Section O3.1)
Maintenance
. The licensee decontaminated reactor water cleanup system work areas which increased
the licensee's ability to perform maintenance more efficiently. (Section M2.1)
+ The inspectors identified two violations which resulted in the improper installation of a test
velve assembly on an emergency diesel generator. A work planner failed to follow
administrative maintenance process requirements to ensure the associated work package
incorporated information from the vendor manual. In addition, the licensee had not taken
adequate corrective actions following previous similar problems. (Section M3.1)
E09109EiO2
+ The licensee's identification of testing deficiencies involving the emergency diesel
generators was positive and reflected an increased licensee focus on surveillance test
procedure adequacy. These issues were determined to be non-cited violations.
(Sections E1.1 and E8.2)

+ The inspectors identified a violation involving the failure to properly post a contaminated
area. The lack of a questioning attitude by a radiation protection technician and by two
non licensed equipment operators resulted in contaminated liquids being vented into a
plant drain trough which was not identified as contaminated, (Section R1.1)

and engineering personnel.
b. Observation and Findinas
On November 19,1997, a control room supervisor (CRS) unnecessarily entered .
'
Technical Specification (TS) limiting condition for operation (LCO) action
Statement 3.3.7.3 a., following the identifloation of an upscale meteorological differential ;
temperature indication. The CRS was aware of an operability evaluation, No. 97016, that ;
.
had been completed to support operability determination of the meteorological differential j
!
temperaturs instrument during certain atmospheric conditions. - Guidance and analysis in
the operability evaluation would have prevented the need to enter the LCO action -
statement. However, the CRS could not locate the operability evaluation in the control
room file. :
On December 4,1997, the inspectors discussed the LCO entry with the CRS. Following
further review, the inspectors identified a broader conoom regarding the control of
operability evaluations. The inspectors determined that engineering personnel had
removed operability evaluation No.- 97106 from the control room because they anticipated ,
~
the approval of a procedure change which would have required storage of operability
evaluations by engineering personnel outside of the control room. However, the
inspectors determined that the procedure change had not been approved. Also,
engineering personnel did not question the operational impact of removing the operability
evaluations from the control room or verify that the procedure had not yet been
implemented.; Step F.2.n.10 of LAP-220 5 required that operations management file the
- completed operability evaluations in the control room.- The failure of operations
management to maintain on file the completed operability evaluations in the control room
as required by LAP 220 5 is an example of a violation of 10 CFR Part 50, Appendix B, ,
- Criterion V, as described in the attached Notice of Violation (Notice) (50 373/97020-01a;-

On December 8,1997, the operations manager reiterated the procedural requirements by
informing the shift managers to maintain the operability evaluations in the control room.
Also, as a corrective action, operations and engineering personnel performed audits to
determine if any other operability evaluations were missing from the control room files.
They identified that 15 operability evaluations were not being maintained in the control
room. Enseering personnel subsequently filed these operability evaluations in the
control rot. - Operations personnel did not identify any additional instances of
unnecessary TS LCO action statement entries. The inspectors determined the corrective
actions to be appropriate,
c. Conclus19m
Operations personnel did not ensure operability evaluations were proper 1y controlled to
support plant operations. Also, engineering personnel demonstrated a lack of
questioning attitude regarding the operationalimpact of removal of the operability
evaluations from the control room.

b. Observations and Findinas
The licensee was modifying the RWCU system to address material condition deficiencies
in the system including fluid flashing / voiding at the RWCU heat exchangers and pump
vibrations. Maintenance personnel were using the work proceduren at the work site.
Radiation protection personnel were observed by the inspectors at the job site to support
the work. Once the workers completed demolition of the system, the work areas were
decontaminated to allow workers access to the work areas without the constraints of
anti-contamination clothing,
c. Qonclusions
The licensee decontaminated the RWCU work areas which increased the licensee's
ability to perform maintenance more efficiently. No problems were identified by the
inspectors.

a. inaceallon Soone (62707)
The inspectors evaluated the licensee's response to a loose test valve casombly on the
0 EDG and interviewed maintenance and engineering personnel, in addition, the
inspootors observed maintenance of the test valve assernblies and reviewed
documentation and procedures which included:
.- WR 970119536, " Cylinder 15 Test Valve Unattached to Diesel Cylinder"
. Engineering Request (ER) 9707312. " Evaluate Extent of Condition for Test Valve
Cylinder Threads"
'
. LAP 13001, " Action / Work Request Processing," Revision 67
. LaSalle Mechanical Maintenance Surveillance (LMS) DG-01, " Main Emergency
Diesel Unit Surveillances," Revision 18
. Maintenance Memorandum 200-02, " Instructions to Work Package Preparers
(Wott Analysts)," Revision 11
. LAP 10015 " Vendor Information Technical information Program," Revision 7
b. Observations and Findinns
on November 11,1997, an equipment operator found that the test valve adapter for .
'
cylinder 15 on the EDG was loose and could be removed from the cylinder by hand. The
operator was performing pre start checks of the 0 EDG as directed by LaSalle Operating
Surveillance (LOS) DG-M1, " Diesel Generator Operability Test," Revision 35. The
licensee initiated a problem identification form (PlF) and immediately vertfled the test
valves in the four remaining E00s were tight. The licensee investigated the cause of the
loose valve and determined that the threads in the cylinder that held the test valve
adapter failed and that the test valve adapter could not be threaded back into the
housing.
On November 12,1997, a maintenance work analyst developed work instructions and
maintenance personnel reinstalled the test valve assembly. Engineering personnel
completed en operability evaluation and concluded that the loose test valve was an
isolated case and did not impact the operability of the other EDGs. On November 13,
1997, operators declared the 0 EDG operable following successful completion of an
operability surveillance test.
After the licensee declared the o EDG operable, engineering personnelidentified that
Stop E.29.21 in LMS-DG-01, a maintenance procedure used by mechanics to reinstall the
test valve assemblies following periodic maintenance performed prior to the failure -
identified on November 11,1997, was not correct for the valve assemblies currently
installed on the EDGs. Specifically, the procedure was to be used for the previous type of
5

valve that was installed and appropriate valve adapter torque requirements were not
prescribed for the currently installed valves. As the operability of all EDGs was again in
question after the repairs made on the 0 EDO oylinder 15 test valve, plant personnel
identified contingent actions and test valve tortuing equipmerd was staged by the *
appropriate personnel while the operability evauustion was completed.
,
As a result of the licensee's determination that the torque values in LMS DG-01 were not
applicable to the current valve assemblies, the inspector reviewed the work request, ;
- WR 970119536, and identified that the test valve for cylinder 15 on the 0 EDG was !
installed using superoseded vendor information. The work analyst used the original test i
valve installation work procedure from 1995, whloh was different from LMS DG-01, to
generate the WR. The WR required the test volve adapter be tightened until snug with
the valve knob pointing down. However, in August 1997, the licensee's EDG vendor
equipment technical information program (VETIP) manual had been revised to include a
vendor presortbed torque requirement for the test valve adapters of 45 to 50 foot pounds.
The l6censee's process for developing work procedures, defined in LAP 13001
'
Step B.2.5.1, required the work analyst to incorporate work requirements and restrictions
as discussed in Maintenance Memorandum 200-02. Step F.1.d.4 of the maintenance
memorandum required the work analyst to apply applicable information contained in tha
VETIP manual when developing work Instructions. However, the inspectors determined >
that the work analyst did not reference the manual due to familiarity with the test valve :
assembly and a perceived time constraint to retum the EDG to operable status. The .
'
work analyst's failure to reference appropriate documents and incorporate work
requirements discussed in Maintenance Memorandum 200-02 when developing
WR 970119536 for installing a test valve on the O EDG, spoolfically torque requirements
from the VETIP manual, is an example of a violation of 10 CFR Part 50, Appendix B, -
Criterion V, as described in the attached Notice (50 373/97020-01b; 50 374/97020 01b).
Subsequently, engineering and operations personnel again determined the EDGs to be
operable. The inspectors reviewed the operability esaluation and concluded that the i
operability determination was appropriate.
- Engineering personnel determined, in both the initial oporability evaluation and the
!
supporting engineering evaluation, that the loese test valve assembly was an isolated
case and that the repaired test valve assembly had been correctly installed. However,
the inspectors identified that a similar event had occurred at Dresden Station in .
"
November of 1996 which resulted in Nuclear operations Notice .
- (NON DR [Dresden} 12 9618) being issued. Also, on December 12,1996, at LaSalle
County Station, operators had identified ten loose cylinder test valve assemblies on three
EDGs. The operators initiated Problem identification Form 96 5228 in which the shift
manager indicated that the system engineer believed that torque values for the test valve
assemblies needed to be assigned due to the past history of becoming loose.
Maintenance personnel tightened the test valve assemblies but no specific torque values
- were applied, Maintenance personnel noted on the work request that actions should be
taken to keep the test valve assemblies from working loose. Neither engineering nor
-
maintenance personnel performed any follow-up action to either previous occurrence.
The failure of the licensee to identify and implement adequate corrective actions for loose
test valve assemblies on the EDGs is a violation of 10 CFR Part 50, Appendix B,
Criterion XVI, as described in the attached Notice of Violation (50 373/97020-02;
60 374/97020 02).

.
During the licensee's root cause investigation of the test valve failure, station personnel
determined LAP.10015 did not provide clear guidance regarding procedure revisions
which resulted in the maintenance procedure LMS DG-01 not being updated following .
revisions to the VETIP manuals. Engineering personnalinitiated changes to L.AP-10015 ,
to ensure appropriate procedures would be revised following vendor manual revisions, in ,
addition, the inspectors identified that a formal mechanism to ensure vendor information . t
specifically provided to another Commonwealth Edison facility would be reviewed for ,
applicabilNy to other sHes did not exist at the LaSalle Station. However, the Quad Chios :
'
Station EDG system engineer had informally communloated vendor information regarding
the test valve assemblies to the LaSalle system engineer during a poor group meeting in ;
the spring of 1997. The test valve assembly vendor had provided a letter pertaining to the
torquing of the test valve assemblies to Quad Cities Station EDG system engineer in
January 1997.
c. Conclusion
While the safety significance of the loose test valve on the O EDG was minimal, the
licensee's failure to address the past valve failures resulted in the loose test valve
assembly on the o EDG and the inadequate work request to repair the valve. The work
analyst's failure to follow procedures was representative of previous human performance
problems at the LaSalle Station. However, the licensee has identified the corrective
action program and human performance deficiencies at LaSalle and continuws to address
the problems.

Bypass Logic Test," schematic diagrams of the HPCS EDG protective relays, and
discussed the issue with engineering personnel,
b. Observations and Findinas
On November 25,1997, the licensee identified that the surveillance procedure used to
demonstrate that the Unit 1 and Unit 2 HPCS EDGs could supply the normal Division lil
bus loads following a simulated loss of the offsite power from the station auxiliary
transformer (SAT) was inadequate. Technical Specification Surveillance
Requirement 4.8.1.1.2.d.11.b required the licensee to verify that 6 simulated trip of the
EDG overcurrent relays tripped the SAT feed breaker to the Division ill bus and the EDGs
continued to supply the normal bus loads. The TS required that the EDG be operating in
a test mode and connected to its bus. However, the test procedure was not performed
with the EDGs operating, nor did the procedure verify that the overcurrent relays would
operate as designed.
Two sets of overcurrent relays are in the HPCS EDG circuitry. One set of overcurrent
relays, the K35 relays, trip the SAT supply breaker to the Division lll bus when a fault is
sensed. Following an additional one half second delay, the EDG also trips. However, the
EDG will not trip if the fault clears when the SAT breaker opens. The second set of
overcurrent relays, the K33 relays, trip the SAT breaker, providing protection to the EDG
from high current fault conditions from equipment on the Division ill bus. While the
licensee identified inadequate testing of the K35 overcurrent relays, the inspectors
subsequently identified that the K33 overcurrent relays also were not tested. However,
.
the licensee had not yet completed corrective actions at the time the inspectors identified
this related concem. The licensee initiated a PlF to ensure the test procedure would be
revised to provide proper testing. The HPCS systems were inoperable for other reasons
at the time this issue was identified.
The licensee's failure to perform the testing with the EDGs operating and to verify
operation of the overcurrent relays is a violation of TS Surveillance
Requirement 4.8.1.1.2.d.11.b (50-373/97020-03; 50 374/97020-03). This non-repetitive,
licensee-identified and corrected violation is being treated as a Non-Cited Violation,
consistent with Section Vll.B.1 of the NRC Enforcement Policy.
c. Conclusions
The licensee's identification of the testing deficiency was positive. Severallicensee event
reports involving licensee identification of other inadequate test procedures were issued
in 1997. This additional example further confirmed an increased licensee focus on test
procedure adequacy.
E8 Miscellaneous Engineering issues
E8.1 Incorrect Drawina in Updated Final Safety Analysis Report (UFSAR)
a. lnJpection
n Scope (37301)
While observing maintenance related to the RWCU system, the inspectors reviewed the
LaSalle UFSAR, Amendment 11, Chapter 5.4.8, " Reactor Water Cleanup System."
8
.
b. Observations and Findinas
The inspectors identified that RWCU drawings contained in the UFRAR differed from the
actual plant configuration. The UFSAR drawings shewed that the RWCU pump suction
was directly from the recirculation system, upstream of the RWCU system heat
exchangers. The actual plant configuration was with the pump suction downstream of
the system heat exchangers. The RWCU UFSAR draAgs had been revised by the
licensee in the last revision (Amendment 11) of the UFSAR. The previous amendment
contained RWCU drawings that correctly depicted the relationship between the RWCU
pumps and heat exchangers in the plant.
After the inspectors identified the discrepancy, the licensee entered the discrepancy into
the corrective action program by initiating a PIF. However, the initial evaluation of the PIF
by the Event Screening Committeo (ESC) did not result in any action to determine the
cause of the incorrect drawing being submitted in Amendment 11 of the UFSAR. The
inspectors discussed the ESC actions with the corrective action program manager who
then had the ESC review the PlF. Action items were subsequently assigned by the ESC
to determine the cause of RWCU UFSAR drawing aiscrepancy and to provide further
corrective actions as necessary. In addition, the licensee had previously identified the
potential for incorrect UFSAR information to have been used in performing 10 CFR 50.59
safety evaluations and had assigned a corrective action program item to evaluate the
UFSAR change process. No other cases of incorrect drawings being used to revise the
UFSAR were identified by the inspectors. This is considered an inspection Follow-up
Item (50 373/97020-04; 50-374/97020-04) pending further review of the root cause sind
corrective actions by the inspectars.
c. Conclusions
The UFSAR was incorrectly updated with RWCU drawings which were not representative
of the actual LaSalle plant configuration and the licensee was investigating the cause of
drawing discrepancy. The ESC did not initially require actions to determine the cause of
the RWCU drawing discrepancy in the UFSAR which demonstrated a lack of a
questioning attitude by the committee formed for oversight of the corrective action
screening program.
E8.2 fClosed) LER 50-373/97037-00: Diesel Generator Response Time Test Not Consistent
with TS Due to inadequate Review of Procedures.
On November 5,1997, the licensee determined that the acceptance criteria specified in
plant surveillance procedures for the 0,1 A and 2A EDG response time test was not in
compliance with TS. Specifically, the load sequence timer acceptance criteria for the A
and B residual heat removal (RHR) pumps in LTS-500-1(2)09, " Unit 1(2) Integrated
Division i ECCS [ Emergency Core Cooling System) Response Time Surveillance,"
Revision 5(6), and LTS 500-1(2)10, " Unit 1(2) Integrated Division 11 Response Time
Surveillance," Revision 5(5), was 4 to 5 seconds. However, TS Surveillance
Requirement 4.8.1.1.2.d.12 required verification that the automatic load sequence timer
interval was within +/ 10 percent of its design Interval for the 0,1 A, and 2A EDGs. Since
the design interval specified in Section 7.3.1/2.4.3 and Table 8.3.1 of the UFSAR was
5.0 seconds, the minimum intervalin the surveillance should have been 4.5 seconds.
9
___ _
.
Following identification of the improper acceptance critoria, ths licensee declared the
O EDG inoperable because the previous load sequence timer interval surveillance test
performed on March 15,1996, was 4.2 seconds, below the TS minimum of 4.5 seconds.
The licensee reviewed (Fe previous two years of load sequence timer interval
surveillances for the 0,1 A, and 2A EDGs and identified two additional instances of the
time interval being outside of technical spec!fication requirements. The licensee's failure
to meet EDG load response time testing within +/ 10% of 5 seconds is a violation of
TS 4.6.1.1.2.d.12. (50 373/97020-05; 50 374/97020-05). This non-repetitive, licensee-
identified and corrected violation is being treated as a Non Cited Violation, consistent with
"
Section Vll.B.1 of the NRC Enforcement Policy.
Pr'or to declaring the 0 and 1 A EDG's operable, the licensee recalibrated the load-
sequence timer interval to within the TS requirements. !n addition, the licensee planned
to revise the surveillance procedures with the correct RHR pump time delay interval. The
licensee also evaluated the impact of the time delay interval for the A and B RHR pumps
being us low as 4 soconds. Previous response time testing performed on the EDGs
indicated that voltage recovered to within 10 percent of nominalin approximately 2.0
seconds following initialloading of the EDG buses. Since the sequence timer did not
load the EDG with the A and B RHR pumps until a minimum of 4 seconds, adequate bas
voltage was assured prior to RHR pump start and therefore loading the RHR pumps
would not impact EDG operability.

R1 Radiological Protection and Chemistry Controls
R1.1 Unidentified Contaminated Area in the Reactor Buildina
a. Inspection Scope (717EO. 83750)
On November 30,1997, the inspectors observed the radiological work practices of
operations personnel performing checklist items associated with out-of service (OOS)
.
No. 970004551. This work involved venting of the control rod drive (CRD) charging
header.
b. Observations and Findinas
On November 30,1997, the inspectors observed operations personnel venting the CRD
charging line to a drain trough, that was not marked as radiologically contaminated,
without contacting radiation protection (RP) personnel either prior to or following the
evolution. Operations management informed the inspectors that their expectations were
that the operations personnel performing the venting should have identified that the drain
trough was not posted as contaminated and should have informed RP personnel on shift.
The inspectors contacted the shift RP supervisor who ordered a contamination survey of
the drain through and found the accessible intcmal surfaces contaminated at
10,000 dpm/100 cm' beta gamma. Radiation protection technicians then posted the area
as contaminated.

-
Radiation protection management infomied the inspectors that the drain trough was
previously posted as contaminated. However, when the surrounding area was
4 decontaminated, the area was surveyed as not radiologically contaminated and the
posting had been removed. The technician removing the posting did not consider that
operation of the contaminated CRD system vents and drains could potentially
contaminate the draln through.
LaSalle Radiation Protection Procedure (LRP) 50101, Revision 5, required areas with
smearable contamination levels at levels greater than or equal to 1000 dpm/100cm' to be
posted as a contaminated area. The licenroe's failure to post the drain tsough as a
contaminated area is a violation of TS 6.2.0, as described in the attached Notice
(50 373/97020-06; 50-374/97020-06).
c. Conclusions
Radiological protection personnelinappropriately removed postings from a drain trough
which received input from the contaminated CRD charging water vent line. Operations
personnel did not meet their management's expectation by ialling to notify RP personnel
when venting the contaminated system to the drain trough which was not marked as
radiologically contaminated.
