SUBJECT: COMANCHE PEAK STEAM ELECTRIC STATION - NRC INTEGRATED
INSPECTION REPORT 05000445/2007002 AND 05000446/2007002
Dear Mr. Blevins:
On March 23, 2007, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection
at your Comanche Peak Steam Electric Station, Units 1 and 2, facility. The enclosed integrated
inspection report documents the inspection findings which were discussed on March 29, 2007,
with Mr. M. Lucas and other members of your staff.
This inspection examined activities conducted under your licenses as they related to safety and
compliance with the Commission's rules and regulations and with the conditions of your
licenses. The inspectors reviewed selected procedures and records, observed activities, and
interviewed personnel.
The report documents one NRC identified finding of very low safety significance (Green). The
finding was determined to involve a violation of NRC requirements. However, because of the
very low safety significance and because it was entered into your corrective action program, the
NRC is treating the finding as a noncited violation (NCV) consistent with Section VI.A.1 of the
Enforcement Policy. If you contest any NCV in this report, you should provide a response
within 30 days of the date of this inspection report, with the basis for your denial, to the U.S.
Nuclear Regulatory Commission, ATTN.: Document Control Desk, Washington DC 200555-
0001; with copies to the Regional Administrator, Region IV, 611 Ryan Plaza Drive, Suite 400,
Arlington, Texas 76011-4005; the Director, Office of Enforcement, U.S. Nuclear Regulatory
Commission, Washington, DC 20555-0001; and the NRC Resident Inspector at the Comanche
Peak Steam Electric Station.
In accordance with 10 CFR 2.390 of the NRC's "Rules of Practice," a copy of this letter, its
enclosure, and your response (if any) will be made available electronically for public inspection

SUMMARY OF FINDINGS
IR 05000445/2007002, 05000446/2007002; 01/01/2007-03/23/2007; Comanche Peak Steam
Electric Station, Units 1 and 2; Surveillance Testing.
This report covered a 3-month period of inspection by two resident inspectors, three Operations
Engineers, four Engineering Branch Inspectors, and an Emergency Preparedness Inspector.
One Green noncited violation was identified. The significance of most findings is indicated by
their color (Green, White, Yellow, Red) using Inspection Manual Chapter 0609, Significance
Determination Process. Findings for which the significance determination process does not
apply may be Green or may be assigned a severity level after NRC management review. The
NRC's program for overseeing the safe operation of commercial nuclear power reactors is
described in NUREG-1649, ?Reactor Oversight Process, Revision 3, dated July 2000.
A. NRC-Identified and Self-Revealing Findings
Cornerstone: Mitigating Systems
Green. An NRC identified noncited violation of Technical Specification 5.4.1.e was
identified for the failure to establish, implement and maintain written procedures for the
inservice testing program. STA-711, Inservice Testing Program for Pumps and Valves
required a new set of reference values be determined following pump replacement and
all subsequent test results be compared to the new reference values. Station Service
Water Pump 2-02 was declared operable on October 19, 2006, following pump
replacement and, although the new pumps performance was fully acceptable, the
inservice testing requirements to establish new reference values were not performed
and subsequent test results were not compared to the new reference values. On
March 13, 2007, the licensee provided technical justification for the operability of Station
Service Water Pump 2-02, based, in part, on comparison of the new pump performance
with the design flow requirements.
This violation is more than minor because it resulted in a condition where there was a
reasonable doubt of the operability of the pump, and programmatic deficiencies were
identified in the Inservice Testing Program that could lead to significant errors if not
corrected. The violation affected the mitigation system cornerstone objective to ensure
the capability of the station service water system and the attribute of human
performance. The finding has very low safety significance because the pump was
always fully capable of performing its safety function. The cause of the finding has a
crosscutting aspect in the area of human performance with a resources component, in
that, the licensee failed to ensure complete, accurate and up-to-date procedures were
available and adequate to implement the inservice testing program (Section 1R22).
B. Licensee Identified Violations
None.

inspectors utilized Inspection Procedure 71111.02, "Evaluation of Changes, Tests, or
Experiments," for this inspection.
-3- Enclosure
The inspectors reviewed six safety evaluations performed by the licensee since the last
NRC inspection of this area at CPSES. The evaluations were reviewed to verify that
licensee personnel had appropriately considered the conditions under which the
licensee may make changes to the facility or procedures or conduct tests or
experiments without prior NRC approval. The inspectors reviewed three
licensee-performed applicability determinations and 15 screenings, in which licensee
personnel determined that evaluations were not required, to ensure that the exclusion of
a full evaluation was consistent with the requirements of 10 CFR 50.59. Evaluations,
screenings, and applicability determinations reviewed are listed in the attachment to this
report.
The inspectors reviewed and evaluated a sample of recent licensee condition reports to
determine whether the licensee had identified problems related to 50.59 evaluations,
entered them into the corrective action program, and resolved technical concerns and
regulatory requirements. The reviewed condition reports (SMART FORMS) are
identified in the Attachment.
The inspection procedure specifies that the inspectors review a minimum sample of
six licensee safety evaluations and 12 applicability determinations and screenings
(combined). The inspectors completed a review of six licensee safety evaluations and a
combination of 18 applicability determinations and screenings.

1R11 Licensed Operator Requalification (71111.11)
.1 Biennial Inspection (71111.11B)
a. Inspection Scope
The inspectors: (1) evaluated examination security measures and procedures for
compliance with 10 CFR 55.49; (2) evaluated the licensees sample plan for the written
examinations for compliance with 10 CFR 55.59 and NUREG-1021, as referenced in the
facility requalification program procedures; and (3) evaluated maintenance of license
conditions for compliance with 10 CFR 55.53 by review of facility records (medical and
administrative), procedures, and tracking systems for licensed operator training,
qualification, and watchstanding. In addition, the inspectors reviewed remedial training
and examinations for examination failures for compliance with facility procedures and
responsiveness to address areas failed. The inspectors also verified that on-shift
operators requiring prescription lenses for self-containment breathing apparatus (SCBA)
maintained their lenses secured in the control room.
Furthermore, the inspectors (1) interviewed seven personnel (four operators, two
instructors/evaluators, and a training supervisor) regarding the policies and practices for
administering examinations; (2) observed the administration of two dynamic simulator
scenarios to two requalification crews by facility evaluators, including an engineering
department manager, who participated in the crew and individual evaluations; and
(3) observed four facility evaluators administer five job performance measures (JPM),
including two in the control room simulator in a dynamic mode, and three in the plant
under simulated conditions. Each JPM was observed being performed by at least two
requalification candidates.
The inspectors also reviewed the biennial written examinations including two
remediation written examinations for a reactor operator and a senior reactor operator.
The inspectors verified question level of difficulty, knowledge level, and overlap between
successive exams and remediation exams. Additionally, quality audits and training self-
assessments, and training management meeting minutes were reviewed to ascertain
the health of their training feedback processes.
Of the 77 licensed operators taking the biennial examinations, 1 staff license failed a
JPM and 1 reactor operator and 1 senior reactor operator failed the written examination.
The inspectors also reviewed the remediation process for one individual, a JPM failure.
The inspectors also reviewed the results of the annual licensed operator requalification
operating examinations for 2006 and 2007. The results of the examinations were also
reviewed to assess the licensees appraisal of operator performance and the feedback
of that performance analysis to the requalification training program. Inspectors also
observed the examination security maintenance during the examination week.
b. Findings
No significant findings were identified.
-8- Enclosure
.2 Resident Inspector Quarterly Review (71111.11Q)
a. Inspection Scope
The inspectors observed a licensed operator requalification training scenario in the
control room simulator on February 16, 2007. The scenario began with a discussion of
the Integrated Plant Operations (IPO) procedure concerning reduced inventory, changes
involving the temporary reactor vessel head, and possible loss of reactor coolant
system (RCS) heat removal. The operations crew briefed the action of reducing RCS
inventory to 56 inches in accordance with IPO-010A. A loss of the Train B residual heat
removal (RHR) pump event occurred during the inventory reduction. Then the Train A
RHR pump began to experience erratic current and flow readings. The Train A pump
was manually secured. Abnormal condition procedure ABN-104 was entered due the
loss of the RHR system at reduced inventory. Inventory continued to decline, due to an
RCS leak, as operators began to reestablish heat removal. The scenario was
terminated after operators established RCS hot leg injection via the safety injection
pumps prior to RCS temperature reaching 212 degrees.
Simulator observations included formality and clarity of communications, group
dynamics, the conduct of operations, procedure usage, command and control, and
activities associated with the emergency plan. The inspectors also verified that
evaluators and operators were identifying crew performance problems as applicable.
On February 14, 2007, the inspectors also observed a requalification classroom training
session regarding the switchyard system changes, system operation, as well as industry
events. On February 16, 2007, the inspectors observed classroom training regarding
the upcoming Unit 1, Cycle 13 reactor core characteristics following steam generator
replacement.
The inspectors completed one sample.

b. Findings
Introduction: A Green NRC identified noncited violation of TS 5.4.1.e was identified for
the failure to establish, implement, and maintain written procedures for the inservice
testing program. Station Administration Procedure (STA) STA-711, Inservice Testing
Program for Pumps and Valves required a new set of reference values be determined
following pump replacement and all subsequent test results be compared to the new
reference values. Station Service Water Pump 2-02 was declared operable on October
19, 2006, following pump replacement and, although the new pumps performance was
fully acceptable, the inservice testing requirements to establish new reference values
were not performed. Subsequent surveillance tests were performed with the old
reference value as the basis for the test acceptance criterion which was not in
accordance with the ASME code.
Description: On February 21, 2007, surveillance testing of SSWP 2-02 was performed
in accordance with OPT-207B, Service Water System, Revision 12, Section 8.3, and
Data Sheet OPT-207B-5, SSWP 2-02 Data Sheet, Revision 13, to satisfy the quarterly
pump performance surveillance. The measured pump flow of 12,996 gallons per
minute (gpm) did not meet the acceptance criterion (new reference value of 16,761
gpm). The pump was declared inoperable and all appropriate actions were taken,
including reviewing past pump performance. The licensee determined that the pump
had met the surveillance test criterion (old reference value of 13,045 gpm) when last
performed on November 27, 2006, and that the surveillance procedure Data Sheet
OPT-207B-5 had been revised on December 1, 2006, changing to the new reference
value. The licensee issued Revision 14 to the data sheet using the Revision 12
acceptance criterion (i.e., old reference values), evaluated the test results against this
criterion and declared the pump operable.
-15- Enclosure
During Unit 2 refueling outage 2RF09 the SSWP 2-02 had been replaced. On
October 18, 2006, the pump was flow tested in accordance with Equipment Test
Procedure (ETP) ETP-215B, Service Water Pump Test, Revision 2, for the purpose of
obtaining reference values for pump performance (flow, developed pump head, and
vibrations). However, the test did not comply with the applicable ASME OMa
Code-1999 Addenda to ASME OM Code - 1998, Code for Operation and Maintenance
of Nuclear Power Plants which required at least 5 points to be measured after pump
conditions are as stable as the system permits (pump shall be run at least 2 minutes at
each point). Instead, ETP-215B had collected pump data with an automated data
acquisition system as the discharge valve opened on pump start vice throttling to
establish distinct, stable flow conditions. The ETP-215B also collected data at a flow
rate of approximately 16,000 gpm with the intent of using this for the new reference
value during subsequent surveillance testing.
On October 19, 2006, EVAL-2006-003466-02-00 was performed to determine the
operational readiness of the pump based on the results of the ETP-215B. SSWP 2-02
was declared operable based on a comparison of the pump start data with the pump
curve in the Design Basis Document DBD-ME-233, Station Service Water System,
Revision 16, and a comparison of the pump full flow data from ETP-215B to the DBD
design flow of 15,556 gpm. EVAL-2006-003466-02-00 did not establish a new
reference value nor verify whether the previous reference value in the surveillance
procedure was still valid. The DBD design flow value of 15,556 gpm was subsequently
determined to be in error, the actual value should have been 16,456 gpm.
On November 8, 2006, EVAL-2006-003466-01-00 was performed to rebaseline the
SSWP 2-02 based on the ETP-215B results and establish a new reference value for
surveillance procedure OPT-207B, Service Water System. An action item was created
to incorporate the new reference value into the procedure, with a due date of
December 25, 2006. In this evaluation, the full flow value of 16,761 gpm was incorrectly
provided as the reference value (for Section 8.3 of the OPT-207B) which was intended
to be approximately 16,000 gpm. Furthermore, Section 8.3 established a system
configuration with pump developed head of approximately 90 psid, which corresponds to
the previous reference value for a flow of approximately 13,000 gpm. It was not
communicated to the procedure writers that the new reference value for a flow of
16,000 gpm (or 16,761 gpm) required a different system configuration for Section 8.3.
On November 27, 2006, OPT-207B was performed to satisfy the routine quarterly
surveillance requirement. OPT-207B had not yet been revised with the new reference
value and the SSWP 2-02 was declared operable based on the previous reference
value. On December 1, 2006, OPT-207B was revised to incorporate the new reference
value from EVAL-2006-003466-01-00. Section 8.3 of the procedure still established
system conditions of pump developed head of approximately 90 psid, but with a flow
rate (16,761 gpm) that was more appropriate for a developed head of approximately
57 psid. On February 21, 2007, when the new reference values were used for the first
time, SSWP 2-02 failed to satisfy the test acceptance criterion.
On February 22, 2007, a plant event review committee (PERC) meeting was held to
determine the cause of SSWP 2-02 failing to meet the acceptance criterion of Data
Sheet OPT-207B-5, Revision 13. Although the PERC came to the conclusion that the
-16- Enclosure
data sheet was incorrect, other related issues remained unresolved, including the
inspectors concerns about the operability of SSWP 2-02 and the basis for determining
that the pump was operable.
On February 28, 2007, another PERC was held to address these issues and to identify
other contributing causes of the inadequate surveillance Procedure OPT-207B. On
March 13, 2007, EVAL-2007-000556-01-02 provided the technical justification for the
operability of SSWP 2-02, based on comparison of the new pump performance obtained
from ETP-215B and both surveillance tests with the correct design flow requirement of
16,456 gpm at full flow, as well as the DBD pump curve and the previous pump
performance. This evaluation also documented the failure to comply with the ASME
Code following the pump replacement, in that an adequate baseline pump test had not
been performed, nor was a new reference value determined. ETP-215B has been
revised to incorporate the ASME requirements and will be performed at the next
available work window. New reference values and limits will be determined and
incorporated into OPT-207B.
Analysis: The performance deficiency was the failure to implement STA-711 Inservice
Testing Program for Pumps and Valves, which required (1) new reference values be
determined by the test method in the ASME OM Code and (2) the new reference valves
be used for all subsequent testing. The inspectors determined that the finding is more
than minor because it affected the mitigation system cornerstone attribute of human
performance (pre-event) and objective to ensure the capability of the SSW system to
respond to initiating events with sufficient flow to prevent core damage. This finding
does not affect the initiating event of loss of service water because the potential
consequence is not a loss of flow but degraded flow. Degraded flow would not
challenge the SSW systems ability to provide operational cooling to the component
cooling water system. This finding is also similar to Examples 3.j and 3.k of Appendix E
of IMC-0612, in that it is not minor because it resulted in a condition where there was
now a reasonable doubt on the operability of the SSWP 2-02, and programmatic
deficiencies were identified in the implementation of the Inservice Testing Program that
could lead to worse errors if not corrected. The significance of the finding is very low
(Green) because the SSWP 2-02 was always fully capable of performing its safety
function. The finding was screened as Green in Phase 1 of the significance
determination process because it did not involve an actual loss of any safety function,
nor contributed to external event initiated core damage accident sequences (i.e.,
initiated by seismic, flooding, or severe weather event).
The finding had a crosscutting aspect in the area of human performance with a
resources component, in that, the licensee failed to ensure complete, accurate and
up-to-date procedures were available and adequate to ensure nuclear safety.
Specifically, ETP-215B, Service Water Pump Test, Revision 2 did not comply with the
ASME Code requirements for testing following pump repair, OPT-207B, Service Water
System, Revision 12 with Data Sheet OPT-207B-5 R-13 was not adequate for the
quarterly surveillance test, and no procedure ensured the new reference values were
incorporated into surveillance procedures prior to their use.
Enforcement: Technical Specification 5.4.1.e requires written procedures be
established and implemented for the Inservice Testing Program. Station Administrative
-17- Enclosure
Procedure STA-711, Inservice Testing Program for Pumps and Valves, Revision 6,
Section 6.3.3 required that when a reference value or set of reference values may have
been affected by repair, replacement, or routine maintenance of a pump, the
requirements of ASME OM Code - 1998, Code for Operation and Maintenance of
Nuclear Power Plants, Section ISTB-3310 shall be met. ASME OMa Code - 1999
Addenda to ASME OM Code, Section ISTB-3310 required a new reference value or set
of values shall be determined in accordance with ISTB-3300, or the previous value
reconfirmed by a comprehensive or Group A test run before declaring the pump
operable. Deviations between the previous and new set of reference values shall be
evaluated, and verification that the new values represent acceptable pump operation
shall be placed in the record of tests. The ASME OM Code also required all subsequent
test results shall be compared to new reference values. Contrary to the above,
SSWP 2-02 was declared operable on October 19, 2006, without determining the
required new reference values in accordance with the required test method.
Subsequent surveillance test results were compared to the previous reference values
without first reconfirming their validity. This violation was entered into the licensees
corrective action program as SMF-2007-000556-00. Since this violation is of very low
safety significance and has been entered into the corrective action program, it is being
treated as a noncited violation, consistent with Section VI.A.1 of the NRC Enforcement
Policy (NCV 05000446/2007002-01, Failure to Perform Required Inservice Testing
Following Pump Replacement).
4. OTHER ACTIVITIES
4OA1 Performance Indicator Verification (71151)
a. Inspection Scope
The inspectors reviewed a sample of performance indicator data submitted by the
licensee regarding the initiating events cornerstone to verify that the licensees data was
reported in accordance with the requirements of Nuclear Energy Institute NEI 99-02,
Regulatory Assessment Performance Indicator Guideline, Revision 4. The sample
included data taken from control room operator logs, the SMF database, and licensee
event reports for January 2005 through December 2006 for the following performance
indicators:
- Units 1 and 2, unplanned scrams per 7,000 critical hours
- Units 1 and 2, unplanned scrams with loss of normal heat removal
- Units 1 and 2, unplanned power changes per 7,000 critical hours
During plant tours, inspectors periodically determined if access to high radiation areas
was properly controlled and if potentially unmonitored release pathways were present.
The inspectors completed six samples.

4OA2 Problem Identification and Resolution (71152)
Review of Items Entered into the Corrective Action Program
a. Inspection Scope
As required by Inspection Procedure 71152, "Identification and Resolution of Problems,
and in order to identify repetitive equipment failures or specific human performance
issues for follow-up, the inspectors performed a routine screening of all items entered
into the licensees corrective action program. This review was accomplished by
reviewing the licensees computerized corrective action program database, reviewing
hard copies of selected SMFs, and attending related meetings such as PERC meetings.
b. Findings
No findings of significance were identified.
4OA3 Event Follow-up (71153)
.1 (Closed) LER 05000446/2006-002 Reactor Trip Due to a Secondary Transient Initiated
During Load Rejection Testing
On October 27, 2006, Unit 2 was in Mode 1 at 28 percent power performing planned
25 MWe load reject tests following digital modifications to the protection circuitry of the
turbine generator. The third 25 MWe swing resulted in a divergent oscillation in the
secondary system. Operators identified the oscillations and took manual control of the
feedwater system, but the level in Steam Generator 2-02 reached the HI-HI setpoint.
The HI-HI level caused a trip of the main turbine and the isolation of main feedwater.
The operators manually tripped the Unit 2 reactor. The licensee determined that there
was enough information gathered to declare testing of the turbine generator digital
upgrade was complete. The licensees corrective actions included: (1) modifying the
procedure for sequencing secondary system pumps, (2) changing gain settings for the
main feedwater pump speed controller back to the previous settings, which had been
changed at 100 percent power to help maintain a tighter feedwater flow rate band and
thus operate closer and more consistently at 100 percent power, and (3) implementing
lessons learned training. More specific event details can be found in Section 4OA3,
Event Followup, of Inspection Report 2006-005. The LER was reviewed by the
inspectors and no findings of significance were identified and no violations of NRC
requirements occurred. The licensee documented the event in their corrective action
program in SMF-2006-003632-00. This LER is closed.
-19- Enclosure
.2 (Closed) LER 05000446/2006-003 Unit 2 Reactor Trip Due to Feedwater Regulating
Valve Malfunction
On October 29, 2006, Unit 2 was in Mode 1 at 80 percent power and holding for Xenon
stabilization, when a manual reactor trip was initiated due to Steam Generator 2-03 level
lowering uncontrollably. The licensee investigated and determined that Solenoid
Valve SV-2 associated with Feedwater Regulating Control Valve 2-FCV-530, had a
loose wire. The loss of continuity resulted in the loss of air between the valve positioner
and the valve operator diaphragm, causing the flow control valve to fail closed. The
licensee was able to duplicated the failure in the valve workshop. Corrective actions
included: (1) reviewing and checking the other Unit 2 feedwater regulating control valves
on Unit 2 prior to restart, (2) inspecting Unit 1 feedwater regulating control valves, and
(3) modifying the maintenance procedure to ensure that the wires in the terminal blocks
are tight. More specific details can be found in Section 4OA3.2, Event Followup, of
Inspection Report 2006-005. The LER was reviewed by the inspectors and no findings
of significance were identified and no violations of NRC requirements occurred. The
licensee documented the event in the corrective action program as
SMF-2006-003660-00. This LER is closed.
