Subject: COLUMBIA GENERATING STATION - NRC INTEGRATED INSPECTION REPORT
NUMBER 05000397/2011002
Dear Mr. Reddemann:
On March 26, 2011, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection
at your Columbia Generating Station. The enclosed integrated inspection report documents the
inspection findings, which were discussed on March 31, 2011, with yourself, and other members
of your staff.
The inspections examined activities conducted under your license as they relate to safety and
compliance with the Commissions rules and regulations and with the conditions of your license.
The inspectors reviewed selected procedures and records, observed activities, and interviewed
personnel.
Based on the results of this inspection, the NRC has determined that one Severity Level IV
violation of NRC requirements occurred. The NRC has also identified one NRC identified issue
that was evaluated under the risk significance determination process as having very low safety
significance (Green). The NRC has determined that a violation is associated with this issue.
However, because of the very low safety significance and because they were entered into your
corrective action program, the NRC is treating these findings as noncited violations, consistent
with Section 2.3.2.a of the NRC Enforcement Policy.
If you contest the violation or the significance of the noncited violation, 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, D.C.
20555-0001, with copies to the Regional Administrator, U.S. Nuclear Regulatory Commission,
Region IV, 612 E. Lamar Blvd, Suite 400, Arlington, Texas, 76011-4125; the Director, Office of
Enforcement, U.S. Nuclear Regulatory Commission, Washington, D.C. 20555-0001; and the
NRC Resident Inspector at the facility. In addition, if you disagree with the cross-cutting aspect
assigned to any finding in this report, you should provide a response within 30 days of the date
of this inspection report, with the basis for your disagreement, to the Regional Administrator,
Region IV, and the NRC Resident Inspector at the facility.
Energy Northwest -2-
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 you choose to provide one for cases where a response is not

SUMMARY OF FINDINGS
IR 05000397/2011002; 01/01/2011 - 03/26/2011; Columbia Generating Station, Integrated
Resident and Regional Report; Postmaintenance Testing, Identification and Resolution of
Problems
The report covered a 3-month period of inspection by resident inspectors and announced
baseline inspections by region-based inspectors. One Green noncited violation of significance
and one Severity Level IV violation were identified. The significance of most findings is
indicated by their color (Green, White, Yellow, or Red) using Inspection Manual Chapter 0609,
Significance Determination Process. The cross-cutting aspect is determined using Inspection
Manual Chapter 0310, Components Within the Cross-Cutting Areas. Findings for which the
significance determination process does not apply may be Green or 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 4, dated December 2006.
A. NRC-Identified Findings and Self-Revealing Findings
Cornerstone: Mitigating Systems
- Green. The inspectors identified a noncited violation of 10 CFR Part 50
Appendix B, Criterion V, Instructions, Procedures, and Drawings, for the
licensees failure to consider the impact of preconditioning on the emergency
core cooling systems during maintenance. Specifically, licensee personnel failed
to consider the impact of scheduling keep fill pump maintenance prior to
technical specification required surveillance testing. Licensee personnel
reviewed three years worth of data on the emergency core cooling systems to
ensure there was no degrading performance trend. This issue was placed in the
licensees corrective action program as Action Request/Condition
Report 236880.
The performance deficiency was more than minor because it affected the
equipment performance attribute of the Mitigating Systems Cornerstone objective
of ensuring the reliability of systems that respond to initiating events. Using
Inspection Manual Chapter 0609.04, Phase 1 - "Initial Screening and
Characterization of Findings, the inspectors determined that this performance
deficiency was of very low safety significance because this finding was confirmed
to not result in a loss of operability for the emergency core cooling systems. The
inspectors identified a cross-cutting issue in the area of human performance,
work practices, because the licensee failed to effectively communicate
expectations regarding procedural compliance H.4.b] (Section 1R19).
Cornerstone: Miscellaneous
- Severity Level IV. The inspectors identified a Severity Level IV violation of 10
CFR 50.72(b)(3)(v)(D) for the failure of the licensee to make a non-emergency
-2- Enclosure
event notification to the NRC. Specifically, on December 20, 2010, the licensee
failed to report the low pressure core spray minimum flow valve failing to open on
pump start, rendering the low pressure core spray system incapable of
performing its specified safety function during testing. The licensee made Event
Notification 46604 on February 8, 2011, to report the identified condition. As a
corrective action the licensee has informed all current shift managers, and plans
to train future senior reactor operators, of the expectation to evaluate low
pressure core spray system failures as a failure of a single train system to
complete a safety function. This violation has been placed in the licensees
corrective action program as Action Request/Condition Report 236879.
The performance deficiency was more than minor because the NRC relies on
licensees to identify and report conditions or events meeting the criteria specified
in the regulations in order to perform its regulatory function. The inspectors
determined that this finding was not appropriate to evaluate using the
Significance Determination Process due to the finding only affecting the NRCs
ability to perform its regulatory oversight function. As a result, this finding was
evaluated for traditional enforcement in accordance with the NRC Enforcement
Policy. This finding was determined to be a Severity Level IV violation in
accordance with Section 6.9.d.9 of the NRC Enforcement Policy, dated
September 30, 2010. The inspectors determined that assigning a cross-cutting
aspect was not applicable to this finding due to the finding being screened
exclusively using the traditional enforcement process (Section 4OA2).

REPORT DETAILS
Summary of Plant Status
The plant began the inspection period at 100 percent power. The plant remained at 100 percent
power for the remainder of the inspection period except for planned power reductions to support
maintenance and testing.
1. REACTOR SAFETY
Cornerstones: Initiating Events, Mitigating Systems, Barrier Integrity, and
1R01 Adverse Weather Protection (71111.01)
Readiness for Seasonal Extreme Weather Conditions
a. Inspection Scope
The inspectors performed a review of the adverse weather procedures for seasonal
extremes (e.g., extreme high temperatures, extreme low temperatures, or hurricane
season preparations). The inspectors verified that weather-related equipment
deficiencies identified during the previous year were corrected prior to the onset of
seasonal extremes, and evaluated the implementation of the adverse weather
preparation procedures and compensatory measures for the affected conditions before
the onset of, and during, the adverse weather conditions.
During the inspection, the inspectors focused on plant-specific design features and the
procedures used by plant personnel to mitigate or respond to adverse weather
conditions. Additionally, the inspectors reviewed the FSAR and performance
requirements for systems selected for inspection, and verified that operator actions were
appropriate as specified by plant-specific procedures. Specific documents reviewed
during this inspection are listed in the attachment. The inspectors also reviewed
corrective action program items to verify that plant personnel were identifying adverse
weather issues at an appropriate threshold and entering them into their corrective action
program in accordance with station corrective action procedures. The inspectors
reviews focused specifically on the following plant systems:
- February 25, 2011, diesel generator rooms, service water pump houses and
circulating water pump houses due to extreme low temperatures being
forecasted for the day
These activities constitute completion of one readiness for seasonal adverse weather
sample as defined in Inspection Procedure 71111.01-05.
b. Findings
No findings were identified.
-4- Enclosure
1R04 Equipment Alignments (71111.04)
Partial Walkdown
a. Inspection Scope
The inspectors performed partial system walkdowns of the following risk-significant
systems:
- January 5, 2011, residual heat removal system C
- February 14, 2011, diesel generator 1
The inspectors selected these systems based on their risk significance relative to the
reactor safety cornerstones at the time they were inspected. The inspectors attempted
to identify any discrepancies that could affect the function of the system, and, therefore,
potentially increase risk. The inspectors reviewed applicable operating procedures,
system diagrams, FSAR, technical specification requirements, administrative technical
specifications, outstanding work orders, condition reports, and the impact of ongoing
work activities on redundant trains of equipment in order to identify conditions that could
have rendered the systems incapable of performing their intended functions. The
inspectors also inspected accessible portions of the systems to verify system
components and support equipment were aligned correctly and operable. The
inspectors examined the material condition of the components and observed operating
parameters of equipment to verify that there were no obvious deficiencies. The
inspectors also verified that the licensee had properly identified and resolved equipment
alignment problems that could cause initiating events or impact the capability of
mitigating systems or barriers and entered them into the corrective action program with
the appropriate significance characterization. Specific documents reviewed during this
inspection are listed in the attachment.
These activities constitute completion of two partial system walkdown samples as
defined in Inspection Procedure 71111.04-05.
b. Findings
No findings were identified.
1R05 Fire Protection (71111.05)
Quarterly Fire Inspection Tours
a. Inspection Scope
The inspectors conducted fire protection walkdowns that were focused on availability,
accessibility, and the condition of firefighting equipment in the following risk-significant
plant areas:
-5- Enclosure
- January 6, 2011, fire area RC-4, division 1 switch gear room
- January 10, 2011, fire area R-8/1, low pressure core spray pump room
- January 12, 2011, fire area R-1/1, reactor building 522 elevation northwest
quadrant
- February 14, 2011, fire area DG-2, division 1 diesel generator room
- February 16, 2011, fire area R-5, residual heat removal pump 2A room
The inspectors reviewed areas to assess if licensee personnel had implemented a fire
protection program that adequately controlled combustibles and ignition sources within
the plant; effectively maintained fire detection and suppression capability; maintained
passive fire protection features in good material condition; and had implemented
adequate compensatory measures for out of service, degraded or inoperable fire
protection equipment, systems, or features, in accordance with the licensees fire plan.
The inspectors selected fire areas based on their overall contribution to internal fire risk
as documented in the plants Individual Plant Examination of External Events with later
additional insights, their potential to affect equipment that could initiate or mitigate a
plant transient, or their impact on the plants ability to respond to a security event. Using
the documents listed in the attachment, the inspectors verified that fire hoses and
extinguishers were in their designated locations and available for immediate use; that
fire detectors and sprinklers were unobstructed; that transient material loading was
within the analyzed limits; and fire doors, dampers, and penetration seals appeared to
be in satisfactory condition. The inspectors also verified that minor issues identified
during the inspection were entered into the licensees corrective action program.
Specific documents reviewed during this inspection are listed in the attachment.
These activities constitute completion of five quarterly fire-protection inspection samples
as defined in Inspection Procedure 71111.05-05.
b. Findings
No findings were identified.
1R11 Licensed Operator Requalification Program (71111.11)
.1 Quarterly Review
a. Inspection Scope
On February 14, 2011, the inspectors observed a crew of licensed operators in the
plants simulator to verify that operator performance was adequate, evaluators were
identifying and documenting crew performance problems, and training was being
conducted in accordance with licensee procedures. The inspectors evaluated the
following areas:
-6- Enclosure
- Licensed operator performance
- Crews clarity and formality of communications
- Crews ability to take timely actions in the conservative direction
- Crews prioritization, interpretation, and verification of annunciator alarms
- Crews correct use and implementation of abnormal and emergency procedures
- Control board manipulations
- Oversight and direction from supervisors
- Crews ability to identify and implement appropriate technical specification
actions and emergency plan actions and notifications
The inspectors compared the crews performance in these areas to preestablished
operator action expectations and successful critical task completion requirements.
Specific documents reviewed during this inspection are listed in the attachment.
These activities constitute completion of one quarterly licensed-operator requalification
program sample as defined in Inspection Procedure 71111.11.
b. Findings
No findings were identified.
.2 Biennial Inspection (71111.11B)
The licensed operator requalification program involves two training cycles that are
conducted over a 2-year period. In the first cycle, the annual cycle, the operators are
administered an operating test consisting of job performance measures and simulator
scenarios. In the second part of the training cycle, the biennial cycle, operators are
administered an operating test and a comprehensive written examination.
a. Inspection Scope
To assess the performance effectiveness of the licensed operator requalification
program, the inspectors conducted personnel interviews, reviewed both the operating
tests and written examinations, and observed ongoing operating test activities.
The inspectors interviewed four licensee personnel, consisting of instructors and training
management, to determine their understanding of the policies and practices for
administering requalification examinations. The inspectors also reviewed operator
performance on the written exams and operating tests. These reviews included
observations of portions of the operating tests by the inspectors. The operating tests
-7- Enclosure
observed included six job performance measures and three scenarios that were used in
the current biennial requalification cycle. These observations allowed the inspectors to
assess the licensee's effectiveness in conducting the operating test to ensure operator
mastery of the training program content. The inspectors also reviewed medical records
of six licensed operators for conformance to license conditions and the licensees
system for tracking qualifications and records of license reactivation for two operators.
The results of these examinations were reviewed to determine the effectiveness of the
licensees appraisal of operator performance and to determine if feedback of
performance analyses into the requalification training program was being accomplished.
The inspectors interviewed members of the training department and reviewed six
Licensee Event Reports to assess the responsiveness of the licensed operator
requalification program to incorporate the lessons learned from plant events. In addition,
the inspectors reviewed examination security measures, a sample of simulator
performance test records (transient and steady-state tests, malfunction tests, and
scenario-based tests), simulator fidelity and existing logs of simulator deficiencies.
Examination results were assessed to determine if they were consistent with the
guidance contained in NUREG 1021, "Operator Licensing Examination Standards for
Power Reactors," Revision 9, Supplement 1, and NRC Manual Chapter 0609,
Appendix I, "Operator Requalification Human Performance Significance Determination
Process."
The inspectors completed one inspection sample of the biennial licensed operator
requalification program.
b. Findings
No findings were identified.
1R12 Maintenance Effectiveness (71111.12)
a. Inspection Scope

- March 2, 2011, Action Request/Condition Report 234859, CRD-HCU-1843
scram outlet valve leaks by"
- March 2, 2011, Review of 10 CFR 50.65(a)(3) evaluation
The inspectors reviewed events such as where ineffective equipment maintenance has
resulted in valid or invalid automatic actuations of engineered safeguards systems and
-8- Enclosure
independently verified the licensee's actions to address system performance or condition
problems in terms of the following:
- Implementing appropriate work practices
- Identifying and addressing common cause failures
- Scoping of systems in accordance with 10 CFR 50.65(b)
- Characterizing system reliability issues for performance
- Charging unavailability for performance
- Trending key parameters for condition monitoring
- Ensuring proper classification in accordance with 10 CFR 50.65(a)(1) or -(a)(2)
- Verifying appropriate performance criteria for structures, systems, and
components classified as having an adequate demonstration of performance
through preventive maintenance, as described in 10 CFR 50.65(a)(2), or as
requiring the establishment of appropriate and adequate goals and corrective
actions for systems classified as not having adequate performance, as described
The inspectors assessed performance issues with respect to the reliability, availability,
and condition monitoring of the system. In addition, the inspectors verified maintenance
effectiveness issues were entered into the corrective action program with the appropriate
significance characterization. Specific documents reviewed during this inspection are
listed in the attachment.
These activities constitute completion of three quarterly maintenance effectiveness
samples as defined in Inspection Procedure 71111.12-05.
b. Findings
No findings were identified.
1R13 Maintenance Risk Assessments and Emergent Work Control (71111.13)
a. Inspection Scope
The inspectors reviewed licensee personnel's evaluation and management of plant risk
for the maintenance and emergent work activities affecting risk-significant and safety-
related equipment listed below to verify that the appropriate risk assessments were
performed prior to removing equipment for work:
-9- Enclosure
- February 3, 2011, Action Request 233580, "500 KV Relay Set 1 Spurious Trip
Tone Signals"
- March 1, 2011, Yellow risk due to I&C testing and removal of the 500 KV north
bus from service
- March 7, 2011, Yellow risk due to stator cooling water pump maintenance
The inspectors selected these activities based on potential risk significance relative to
the reactor safety cornerstones. As applicable for each activity, the inspectors verified
that licensee personnel performed risk assessments as required by 10 CFR 50.65(a)(4)
and that the assessments were accurate and complete. When licensee personnel
performed emergent work, the inspectors verified that the licensee personnel promptly
assessed and managed plant risk. The inspectors reviewed the scope of maintenance
work, discussed the results of the assessment with the licensee's probabilistic risk
analyst or shift technical advisor, and verified plant conditions were consistent with the
risk assessment. The inspectors also reviewed the technical specification requirements
and inspected portions of redundant safety systems, when applicable, to verify risk
analysis assumptions were valid and applicable requirements were met. Specific
documents reviewed during this inspection are listed in the attachment.
These activities constitute completion of three maintenance risk assessments and
emergent work control inspection samples as defined in Inspection
Procedure 71111.13-05.
b. Findings
No findings were identified.
1R15 Operability Evaluations (71111.15)
a. Inspection Scope
The inspectors reviewed the following issues:
- January 5, 2011, Action Request/Condition Report 231738, Diesel Generator 2

Case is Cracked"
- 10 - Enclosure
- February 28, 2011, Action Request/Condition Report 234766, DMA-FN-31
Electrical Phase Imbalance Noted at Motor Starter
The inspectors selected these potential operability issues based on the risk significance
of the associated components and systems. The inspectors evaluated the technical
adequacy of the evaluations to ensure that technical specification operability was
properly justified and the subject component or system remained available such that no
unrecognized increase in risk occurred. The inspectors compared the operability and
design criteria in the appropriate sections of the technical specifications and FSAR to the
licensee personnels evaluations to determine whether the components or systems were
operable. Where compensatory measures were required to maintain operability, the
inspectors determined whether the measures in place would function as intended and
were properly controlled. The inspectors determined, where appropriate, compliance
with bounding limitations associated with the evaluations. Additionally, the inspectors
also reviewed a sampling of corrective action documents to verify that the licensee was
identifying and correcting any deficiencies associated with operability evaluations.
Specific documents reviewed during this inspection are listed in the attachment.
These activities constitute completion of five operability evaluations inspection samples
as defined in Inspection Procedure 71111.15-04
b. Findings
No findings were identified.
1R18 Plant Modifications (71111.18)
a. Inspection Scope
To verify that the safety functions of important safety systems were not degraded, the
inspectors reviewed the temporary modification identified as Temporary Modification
TMR-11-008, "Crack in Weld Down Stream of BS-V-52A"
The inspectors reviewed the temporary modification and the associated safety-
evaluation screening against the system design bases documentation, including the
FSAR and the technical specifications, and verified that the modification did not
adversely affect the system operability/availability. The inspectors also verified that the
installation and restoration were consistent with the modification documents and that
configuration control was adequate. Additionally, the inspectors verified that the
temporary modification was identified on control room drawings, appropriate tags were
placed on the affected equipment, and licensee personnel evaluated the combined
effects on mitigating systems and the integrity of radiological barriers.
These activities constitute completion of one sample for temporary plant modifications as
defined in Inspection Procedure 71111.18-05.
- 11 - Enclosure
b. Findings
No findings were identified.

The inspectors selected these activities based upon the structure, system, or
component's ability to affect risk. The inspectors evaluated these activities for the
following:
- The effect of testing on the plant had been adequately addressed; testing was
adequate for the maintenance performed
- Acceptance criteria were clear and demonstrated operational readiness; test
instrumentation was appropriate
The inspectors evaluated the activities against the technical specifications, the FSAR, 10
CFR Part 50 requirements, licensee procedures, and various NRC generic
communications to ensure that the test results adequately ensured that the equipment
met the licensing basis and design requirements. In addition, the inspectors reviewed
corrective action documents associated with postmaintenance tests to determine
whether the licensee was identifying problems and entering them in the corrective action
program and that the problems were being corrected commensurate with their
importance to safety. Specific documents reviewed during this inspection are listed in
the attachment.
- 12 - Enclosure
These activities constitute completion of six postmaintenance testing inspection samples
as defined in Inspection Procedure 71111.19-05.
b. Findings
Introduction: The inspectors identified a noncited violation of 10 CFR Part 50, Appendix
B, Criterion V, Instructions, Procedures, and Drawings, for the failure to consider the
impact of preconditioning on the emergency core cooling systems during keep fill pump
maintenance in the work management process.
Description: On February 3, 2011, the inspectors identified that the work schedule for
the keep fill pump maintenance performed on December 20, 2010, could have resulted
in the unacceptable preconditioning of the low pressure core spray system. The
licensee was scheduled to start the low pressure core spray pump to perform
Surveillance Procedure SOP-LPCS-SP, LPCS Suppression Pool Mixing, to support
keep fill pump maintenance on the low pressure core spray system. During low
pressure core spray pump start, the minimum flow valve strokes open to protect the
pump from damage. The low pressure core spray minimum flow valve is scoped into the
licensees inservice testing program; which requires the licensee to test the valve in an
as-found condition without preconditioning of the valve prior to inservice testing.
Preconditioning, as defined in the licensees inservice testing program, is the
manipulation of the physical condition of a component before technical specification
surveillance testing. Unacceptable preconditioning is further defined to be
preconditioning that alters one or more attributes of components which results in
acceptable test results. The licensees definition of unacceptable preconditioning goes
on to further state that any activity performed prior to an inservice test which results in
acceptable test results, but may have adversely affected the ability to monitor the
component for degradation. Once the keep fill pump maintenance was completed, the
licensee was scheduled to complete the required technical specification surveillance test
on the low pressure core spray system. This technical specification surveillance test is
used to test the time the low pressure core spray minimum flow valve takes to stroke
from fully closed to fully open, among other attributes of the low pressure core spray
system. This test is performed to ensure the low pressure core spray system can meet
its specified design function, and to detect a degrading performance trend before
operability is challenged.
The inspectors reviewed the licensees technical position on preconditioning within its
inservice testing program plan to determine what the licensee had defined to be
unacceptable preconditioning. The inspectors identified that one of the examples of
unacceptable preconditioning listed in the licensees inservice testing program was the
exercising of a motor-operated valve other than for test configurations or normal system
operation prior to a surveillance test on the valve. The inspectors also reviewed NRC
Inspection Manual Chapter 9900, "Maintenance-Preconditioning of Structures, Systems,
and Components Before Determining Operability." The inspectors noted that
preconditioning could mask the actual as-found condition of components and possibly
result in an inability to verify the operability of components. The inspectors also noted in
the NRC technical guidance, that the scheduling of apparently unrelated activities could
- 13 - Enclosure
result in unacceptable preconditioning. The inspectors determined that the scheduling of
the keep fill pump maintenance, which requires the starting of the low pressure core
spray system and the cycling of the minimum flow valve, prior to technical specification
surveillance testing constituted unacceptable preconditioning by the licensee.
The inspectors reviewed keep fill pump maintenance scheduling records for the previous
three years and noted the following additional occurrences of unacceptable
preconditioning on emergency core cooling systems:
- 4/22/2008 high pressure core spray system started for keep fill pump maintenance.
4/25/2008 high pressure core spray system started for technical specification
surveillance testing.
- 7/14/2008 high pressure core spray system started for keep fill pump maintenance.
7/18/2008 high pressure core spray system started for technical specification
surveillance testing.
- 10/7/2008 high pressure core spray system started for keep fill pump maintenance.
10/8/2008 high pressure core spray system started for technical specification
surveillance testing.
- 11/23/2009 low pressure core spray system started for keep fill pump maintenance.
11/27/2009 low pressure core spray system started for technical specification
surveillance testing.
- 5/17/2010 high pressure core spray system started for keep fill pump maintenance.
5/19/2010 high pressure core spray system started for technical specification
surveillance testing.
- 8/11/2010 high pressure core spray system started for keep fill pump maintenance.
8/14/2010 high pressure core spray system started for technical specification
surveillance testing.
- 9/8/2010 high pressure core spray system started for keep fill pump maintenance.
9/8/2010 high pressure core spray system started for technical specification
surveillance testing.
- 2/2/2011 residual heat removal system, train C, started for keep fill pump
maintenance.
2/3/2011 residual heat removal system, train C, started for technical specification
surveillance testing.
The inspectors determined, through interviews with the licensees staff, the licensee did
not have clear guidance on how to avoid preconditioning of components during the
scheduling of work or how to resolve issues of preconditioning when identified.
Analysis: The failure to consider preconditioning during the work scheduling process is
a performance deficiency. This performance deficiency is more than minor because it
- 14 - Enclosure
affects the equipment performance attribute of the Mitigating Systems Cornerstone
objective of ensuring the reliability of systems that respond to initiating events.
Specifically, the improper scheduling of maintenance and surveillance activities could
mask a degraded condition such that systems would be unable to perform their intended
safety function when called upon. Using Inspection Manual Chapter 0609.04,
Phase 1 - Initial Screening and Characterization of Findings, the inspectors
determined this performance deficiency was of very low safety significance because the
finding was confirmed to not result in a loss of operability for the emergency core cooling
systems. During interviews with plant personnel the inspectors identified a cross-cutting
issue in the area of human performance, work practices, because the licensee failed to
effectively communicate expectations regarding procedural compliance. In that, the
licensee failed to give clear guidance to work week managers in preparing work
schedules H.4.b].
Enforcement: Title 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures,
and Drawings, requires, in part, that activities affecting quality shall be prescribed by
documented procedures of a type appropriate to the circumstance and shall be
accomplished in accordance with those procedures. Contrary to this, from 2008 through
2010, the licensee failed to ensure aspects of preconditioning are considered during
scheduling of work as specified in Procedure 1.3.68, Work Management Process. This
caused the licensee to fail to realize the scheduling of emergency core cooling systems
keep fill pump maintenance prior to quarterly scheduled surveillance testing constituted
unacceptable preconditioning. This violation was identified on February 3, 2011.
Because this finding was determined to be of very low safety significance and was
entered into the licensees corrective action program as Action Request/Condition
Report 236880, this violation is being treated as a noncited violation consistent with
Section 2.3.2.a of the NRC Enforcement Policy: NCV 05000397/2011002-01, Failure to
Ensure Unacceptable Preconditioning is Considered During the Work Management
Process.

Cornerstones: Initiating Events, Mitigating Systems, Barrier Integrity, Emergency
Preparedness, Public Radiation Safety, Occupational Radiation Safety, and Physical
Protection
.1 Routine Review of Identification and Resolution of Problems
a. Inspection Scope
As part of the various baseline inspection procedures discussed in previous sections of
this report, the inspectors routinely reviewed issues during baseline inspection activities
and plant status reviews to verify that they were being entered into the licensees
corrective action program at an appropriate threshold, that adequate attention was being
given to timely corrective actions, and that adverse trends were identified and
addressed. The inspectors reviewed attributes that included the complete and accurate
identification of the problem; the timely correction, commensurate with the safety
- 19 - Enclosure
significance; the evaluation and disposition of performance issues, generic implications,
common causes, contributing factors, root causes, extent of condition reviews, and
previous occurrences reviews; and the classification, prioritization, focus, and timeliness
of corrective actions. Minor issues entered into the licensees corrective action program
because of the inspectors observations are included in the attached list of documents
reviewed.
These routine reviews for the identification and resolution of problems did not constitute
any additional inspection samples. Instead, by procedure, they were considered an
integral part of the inspections performed during the quarter and documented in
Section 1 of this report.
b. Findings
No findings were identified.
.2 Daily Corrective Action Program Reviews
a. Inspection Scope
In order to assist with the identification of repetitive equipment failures and specific
human performance issues for follow-up, the inspectors performed a daily screening of
items entered into the licensees corrective action program. The inspectors
accomplished this through review of the stations daily corrective action documents.
The inspectors performed these daily reviews as part of their daily plant status
monitoring activities and, as such, did not constitute any separate inspection samples.
b. Findings
No findings were identified.
.3 Selected Issue Follow-up Inspection
a. Inspection Scope
During a review of items entered in the licensees corrective action program, the
inspectors recognized a corrective action item documenting the low pressure core spray
systems minimum flow valve losing position indication during surveillance testing. The
inspectors were concerned that the issue was reportable to the NRC and that the
licensee had failed to do so.
These activities constitute completion of one in-depth selected issue follow-up inspection
sample as defined in Inspection Procedure 71152-05.
- 20 - Enclosure
b. Findings
Introduction: The inspectors identified a Severity Level IV violation of Title 10 CFR
50.72(b)(3)(v)(D) for the failure of the licensee to make a non-emergency event
notification to the NRC. Specifically, the licensee failed to report the low pressure core
spray minimum flow valve failing to open on December 20, 2010, rendering the low
pressure core spray system incapable of performing its specified safety function, during
testing.
Description: On December 20, 2010, while performing Surveillance Procedure SOP-
LPCS-SP, LPCS Suppression Pool Mixing, in support of scheduled maintenance, the
low pressure core spray minimum flow valve failed to open as expected. The low
pressure core spray minimum flow valve is a motor-operated valve which is required to
open when the low pressure core spray system is started. This is done to establish a
flow path from the suppression pool, back to the suppression pool until a flow path can
be established to the reactor vessel to prevent overheating and damage to the low
pressure core spray pump and motor. The low pressure core spray system was
subsequently declared inoperable and an investigation team was assembled to
determine the cause of the failure. The investigation team determined that two of the
three fuses associated with the low pressure core spray motor starter showed internal
melting and discoloration while the third fuse did not. The licensee replaced all three
fuses and performed testing on the low pressure core spray motor starter and returned
the low pressure core spray system to an operable status.
The inspectors questioned the licensee on whether the low pressure core spray system
was capable of performing its specified safety function, at the time of discovery, when
the minimum flow valve failed to open. The inspectors referred to NUREG-1022, Event
Reporting Guidelines 10 CFR 50.72 and 73, Revision 2, and noted the following under
Section 3.2.7, Event or Condition That Could Have Prevented Fulfillment of a Safety
Function:
- The intent of these criteria is to capture those events when there would have
been a failure of a safety system to properly complete a safety function.
- These criteria cover an event or condition where structures, components, or
trains of a safety system could have failed to perform their intended function
because of: [] equipment failures.
- The event must be reported regardless of whether or not an alternate safety
system could have been used to perform the safety function.
- There are a limited number of single train systems that perform safety functions.
For such systems, loss of the single train would prevent the fulfillment of the
safety function of that system and, therefore, is reportable.
The inspectors presented their questions to the licensee on December 29, 2010. The
licensee prepared a position paper that summarized the low pressure core spray system
was not a single train system for reporting purposes, but that it was a redundant system
- 21 - Enclosure
to both the residual heat removal system and the high pressure core spray system.
Therefore, the reporting requirement would not be met due to the previously mentioned
systems being able to provide the appropriate safety function. The licensee position
paper was presented to the inspectors on January 6, 2011. The inspectors reviewed the
FSAR and consulted with NRC regional, headquarters, and training staff to determine
the treatment of the low pressure core spray system for reporting purposes. After
review, the inspectors determined the low pressure core spray system was a single train
system and the failure of the minimum flow valve to open was a reportable condition.
The licensee submitted Event Notification 46604 to the Headquarters Operations Officer
on February 8, 2011.
Analysis: The failure to report a condition that could have prevented the fulfillment of a
systems safety function is a performance deficiency. This finding is more than minor
because the NRC relies on licensees to identify and report conditions or events meeting
the criteria specified in the regulations in order to perform its regulatory function. Using
Inspection Manual Chapter 0612, the inspectors determined that this performance
deficiency was not appropriate to evaluate using the NRCs Significance Determination
Process due to the finding only affecting the NRCs ability to perform its regulatory
oversight function. As a result, this performance deficiency was evaluated for traditional
enforcement in accordance with the NRC Enforcement Policy. This performance
deficiency was determined to be a Severity Level IV violation in accordance with Section
6.9.d.9 of the NRC Enforcement Policy, dated September 30, 2010. The inspectors
determined that assigning a cross-cutting aspect was not applicable to this performance
deficiency due to the performance deficiency being screened exclusively using the
traditional enforcement process.
Enforcement: Title 10 CFR 50.72(b)(3)(v)(D) requires, in part, that licensees shall notify
the NRC within eight hours of the occurrence of an event or condition that at the time of
discovery could have prevented the fulfillment of the safety function of systems that are
needed to mitigate the consequences of an accident. Contrary to this requirement, on
December 20, 2010, the licensee failed to report to the NRC a condition that could have,
at the time of discovery, prevented the low pressure core spray system from fulfilling its
safety function. This violation was identified on December 28, 2010. The licensee made
Event Notification 46604 on February 8, 2011. As a corrective action the licensee has
informed all current shift managers, and plans to train future senior reactor operators, of
the expectation to evaluate low pressure core spray system failures as a failure of a
single train system to complete a safety function. There was no actual or potential
safety consequences associated with this violation. Because this violation was placed
into the licensees corrective action program as Action Request/Condition
Report 236879, compliance was restored within a reasonable amount of time, the
violation was not repetitive, or willful, this Severity Level IV violation is being treated as a
noncited violation, consistent with Section 2.3.2.a of the Enforcement Policy: NCV
05000397/2011002, Failure to Make Required Event Notification.
