SUBJECT: PALO VERDE NUCLEAR GENERATING STATION - NRC INTEGRATED
INSPECTION REPORT 05000528/2009005, 05000529/2009005, AND
05000530/2009005, AND NOTICE OF VIOLATION
Dear Mr. Edington:
On December 31, 2009, the U.S. Nuclear Regulatory Commission (NRC) completed an
integrated inspection at your Palo Verde Nuclear Generating Station, Units 1, 2, and 3, facility.
The enclosed integrated report documents the inspection findings, which were discussed on
January 26, 2010, with Mr. D. Mims, Vice President, Regulatory Affairs, and other members of
your staff.
The inspection examined activities conducted under your licenses as they relate to safety and
compliance with the Commissions rules and regulations and with the conditions of your
licenses. The inspectors reviewed selected procedures and records, observed activities, and
interviewed personnel.
One violation is cited in the enclosed Notice of Violation and the circumstances surrounding it
are described in detail in the subject inspection report. The violation involved failure to establish
and implement an adequate procedure to control essential spray pond missile hazards and
ensure operability of the ultimate heat sink. Although determined to be of very low safety
significance (Green), this violation is being cited in the Notice because not all of the criteria
specified in Section VI.A.1 of the NRC Enforcement Policy for a noncited violation were
satisfied. Specifically, Palo Verde Nuclear Generating Station failed to restore compliance
within a reasonable time after the violation was first identified in NRC Inspection
Report 05000528, 05000529, 05000530/2008004. You are required to respond to this letter
and should follow the instructions specified in the enclosed Notice when preparing your
response. The NRC will use your response, in part, to determine whether further enforcement
action is necessary to ensure compliance with regulatory requirements.
This report documents three self-revealing findings of very low safety significance (Green), and
one Severity Level IV violation. All of these findings were determined to involve violations of
NRC requirements. Additionally, one licensee-identified violation, which was determined to be
of very low safety significance, is listed in this report. However, because of the very low safety
Arizona Public Service Company -2-
significance of these violations and because they were entered into your corrective action
program, the NRC is treating these findings as noncited violations consistent with Section VI.A.1
of the NRC Enforcement Policy. If you contest these noncited violations, 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 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
DC 20555-0001; and the NRC Resident Inspector at the Palo Verde Nuclear Generating
Station, Units 1, 2, and 3, facility. In addition, if you disagree with the characterization of 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 Palo Verde Nuclear Generating Station, Units 1, 2, and 3, facility.
The information you provide will be considered in accordance with Inspection Manual
Chapter 0305.
In accordance with 10 CFR 2.390 of the NRCs Rules of Practice, a copy of this letter, its
enclosure, and your response (if any) will be made available electronically for public inspection
in the NRC Public Document Room or from the Publicly Available Records (PARS) component
of NRCs document system (ADAMS), accessible from the NRC Web site at

NOTICE OF VIOLATION
Arizona Public Service Company Docket Nos.: 50-528,-529,-530
Palo Verde Nuclear Generating Station License Nos.: NPF-41, -51, -74
During an NRC inspection conducted on October 1 through December 31, 2009, a violation of
NRC requirements was identified. In accordance with the NRC Enforcement Policy, the
violation is listed below:
10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings,
requires, in part, that activities affecting quality shall be prescribed by documented
instructions, procedures, or drawings, and shall be accomplished in accordance with
these instructions, procedures, or drawings.
Contrary to the above, from July 11, 2008 through December 31, 2009, the licensee
failed to prescribe adequate procedures for the essential spray ponds. Specifically, the
licensee failed to ensure an adequate procedure was available to control essential spray
pond missile hazards and ensure operability of the ultimate heat sink.
This violation is associated with a Green Significance Determination Process finding.
Pursuant to the provisions of 10 CFR Part 2.201, Arizona Public Service Company is hereby

This report covered a 3-month period of inspection by resident and regional inspectors. Four
Green findings, of which one is a cited violation and three are noncited violations, and one
Severity Level IV finding 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. Findings for which the significance determination process does not
apply may be Green or be assigned a severity level after NRC management's review. The
NRCs 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 and Self-Revealing Findings
Cornerstone: Initiating Events
- Green. A self-revealing noncited violation of 10 CFR Part 50, Appendix B,
Criterion V, "Instructions, Procedures, and Drawings," was identified for the
failure of operations personnel to adequately establish and implement
procedures associated with a loss of instrument air to containment. Specifically,
on December 3, 2009, the alarm response and abnormal operating procedures
available to the Unit 3 control room operating staff were inadequate to
consistently diagnose and mitigate a loss of instrument air to containment. This
issue was entered into the licensees corrective action program as Condition
Report/Disposition Request (CRDR) 3411457.
The performance deficiency associated with this finding involved the failure of
operations personnel to adequately establish and implement alarm response and
abnormal operating procedures associated with a loss of instrument air to
containment. The finding is more than minor because it is associated with the
procedure quality attribute of the Initiating Events Cornerstone and affects the
cornerstone objective of limiting the likelihood of those events that upset plant
stability and challenge critical safety functions during shutdown as well as power
operations. Using Manual Chapter 0609.04, "Phase 1 - Initial Screening and
Characterization of Findings," the finding was determined to have very low safety
significance because the finding did not contribute to both the likelihood of a
reactor trip and the likelihood that mitigation equipment or functions will not be
available. This finding has a crosscutting aspect in the area of problem
identification and resolution associated with the corrective action program
because the licensee failed to implement the corrective action program with a low
threshold for identifying issues P.1(a) (Section 4OA3).
Cornerstone: Mitigating Systems
- Green. The inspectors identified a cited violation of 10 CFR Part 50, Appendix B,
Criterion V, "Instructions, Procedures, and Drawings," for the failure of
engineering personnel to establish adequate procedures to ensure evaluation
and approval of transient missile hazards that have an effect on the operability of
-2- Enclosure 2
the essential spray ponds. Specifically, since January 15, 1997, civil engineering
personnel failed to develop an adequate procedure to verify missile density
criteria are not exceeded to ensure operability of the essential spray ponds
during severe weather. Due to the licensees failure to restore compliance from
the previous NCV 05000528/2008004-04 within a reasonable time, this violation
is being cited in a Notice of Violation consistent with Section VI.A of the NRC
Enforcement Policy. This issue was entered into the licensee's corrective action
program as CRDR 3397839.
The finding is more than minor because it is associated with the external factors
attribute of the Mitigating Systems Cornerstone and affects the cornerstone
objective of ensuring the reliability of systems that respond to initiating events to
prevent undesirable consequences. Using Manual Chapter 0609.04, "Phase 1 -
Initial Screening and Characterization of Findings," the finding was determined to
have very low safety significance because the finding did not result in a loss of
system safety function, an actual loss of safety function of a single train for
greater than its technical specification allowed outage time, or screen as
potentially risk significant due to a seismic, flooding, or severe weather initiating
event. This finding has a crosscutting aspect in the area of problem identification
and resolution associated with the corrective action program because
appropriate corrective actions were not taken to address safety issues and
adverse trends in a timely manner, commensurate with their safety significance
and complexity P.1(d) (Section 1R15).
Cornerstone: Barrier Integrity
- Green. A self-revealing noncited violation of Technical Specification 5.4.1.a,
Procedures, was identified for the failure of maintenance personnel to maintain
containment closure capability as required by Procedure 70DP-0RA01,
Shutdown Risk Assessments. Specifically, on October 8, 2009 maintenance
personnel designated for emergency closure of the containment equipment hatch
left containment to attend a safety briefing for more than four hours before they
returned to perform their required duties. This issue was entered into the
licensee's corrective action program as PVAR 3389284.
The performance deficiency associated with this finding involved the failure of
maintenance personnel to follow the requirements of Procedure 70DP-0RA01,
Shutdown Risk Assessments, and ensure a containment closure team was in
containment and capable of closing the containment equipment hatch within
30 minutes. The finding was more than minor because it affected the
configuration control attribute of the Barrier Integrity Cornerstone, and affected
the cornerstone objective to provide reasonable assurance that physical design
barriers protect the public from radionuclide releases caused by accidents or
events. Using Manual Chapter 0609, Appendix H, Containment Integrity
Significance Determination Process, the finding was determined to be a type B
finding because it affected only large early release frequency, not core damage
frequency, at shutdown. A phase 2 analysis using Table 6.4, Phase 2 Risk
Significance-Type B Findings at Shutdown, was performed with the following
considerations: the plant was in cold shutdown with the reactor coolant system
vented, steam generators not available, and within eight days of shutdown, the
condition existed for less than eight hours, and there was mitigation equipment
-3- Enclosure 2
out of service. The senior reactor analyst determined that that the finding has
very low safety significance (Green) based on the short time period that the
condition existed, the low probability of a loss of cooling event during this period
with two fully-functional trains available, and the time it would have taken to close
the hatch was well less than the time until the core would have become
uncovered. This finding was determined to have a cross cutting aspect in the
area of human performance associated with work control because the licensee
failed to appropriately coordinate work activities by incorporating actions to
address plant conditions that may affect work activities H.3(b) (Section 1R20).
Cornerstone: Occupational Radiation Safety
- Green. A self-revealing noncited violation of Technical Specification 5.7.1, High
Radiation Areas, was identified for the failure of radiological protection personnel
to perform a prejob briefing to ensure workers are aware of radiological
conditions in a high radiation area as required by the radiation exposure permit.
Specifically, on October 20, 2009, nine contract workers were preparing to install
an anticontamination sock over the Unit 2 old reactor vessel head, signed onto a
radiation exposure permit which allowed access to a high radiation area but
failed to receive a brief on the local dose rates surrounding the reactor vessel
head by the job coverage radiation protection technician. This issue was entered
into the corrective action program as CRDR 3394172.
The finding was more than minor because it was associated with the exposure
control attribute of the Occupational Radiation Safety Cornerstone and affected
the cornerstone objective to properly control access to a high radiation area and
had the potential to increase personnel dose. Using Manual Chapter 0609,
Appendix C, Occupational Radiation Safety Significance Determination
Process, the finding was determined to have very low safety significance
because it was not associated with as low as reasonably achievable, there was
no overexposure, there was no substantial potential for an overexposure; and the
ability to assess dose was not compromised. This finding has a crosscutting
aspect in the area of human performance associated with work practices
because the licensees radiation protection staff failed to communicate
expectations to contract personnel H.4(b) (Section 2OS1).
Cornerstone: Public Radiation Safety
- Severity Level IV. The inspectors identified a noncited violation of 10 CFR 50.71
Maintenance of Records, because the licensee failed to update their updated
final safety analysis report with submittals that include the effects of a change
made to the facility. Specifically, the licensee built the old steam generator
storage facility on the owner controlled area for long-term radwaste storage of six
decommissioned steam generators and three reactor vessel heads and failed to
update the updated final safety analysis report to include these changes to the
facility and all safety analyses and evaluations performed. This issue was
entered in the licensees corrective action program as CRDR 3398042.
This issue was dispositioned using traditional enforcement because it had the
potential for impacting the NRCs ability to perform its regulatory function. The
finding is more than minor because it has a material impact on licensed activities
-4- Enclosure 2
in that the six decommissioned steam generators and the Unit 2 reactor vessel
head, with a significant radioactive source term have been relocated from the
plant radiological controlled area to the owner controlled area. In addition, the
radwaste management program was affected because the licensee determined
that this low-level radwaste facility will store these large components until the site
is decommissioned. The finding is characterized as a Severity Level IV, noncited
violation in accordance with NRC Enforcement Policy, Supplement I, and was
treated as a noncited violation consistent with Section VI.A.1 of the NRC
Enforcement Policy. This finding was reviewed for crosscutting aspects and
none were identified because the performance deficiency is not indicative of
current performance (Section 2OS2).
B. Licensee-Identified Violations
A violation of very low safety significance that was identified by the licensee has been
reviewed by the inspectors. Corrective actions taken or planned by the licensee have
been entered into the licensees corrective action program. This violation and corrective
action tracking numbers are listed in Section 4OA7 of this report.

REPORT DETAILS
Summary of Plant Status
Unit 1 operated at essentially full power for the duration of the inspection period.
Unit 2 operated at full power until October 3, 2009, when the unit was shutdown for Refueling
Outage 2R15. The unit was restarted on December 1, 2009, and returned to full power on
December 6, 2009. On December 9, 2009, control room operators lowered reactor power to
approximately 60 percent power and subsequently to 10 percent power to take the main turbine
offline for repairs on the C main transformer. The unit was restarted on December 12, 2009,
and returned to full power on December 15, 2009, and remained at full power for the duration of
the inspection period.
Unit 3 operated at full power until December 3, 2009, when the reactor was tripped and the unit
shutdown due to a loss of instrument air to containment. Repairs were made to the instrument
air system and the unit was restarted on December 5, 2009, and returned to full power on
December 11, 2009, and remained at full power for the duration of the inspection period.
1. REACTOR SAFETY
Cornerstones: Initiating Events, Mitigating Systems, and Barrier Integrity
1R04 Equipment Alignment (71111.04)
.1 Partial Walkdown
a. Inspection Scope
The inspectors performed partial system walkdowns of the following risk-significant
systems:
- November 11, 2009, Unit 1, containment spray system train B
- November 25, 2009, Unit 2, recirculation actuation system train A and B
- December 8, 2009, Unit 2, essential chilled water system train B
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, Updated Final Safety Analysis Report (UFSAR), 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 walked down
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
-6- Enclosure 2
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 three partial system walkdown samples as
defined in Inspection Procedure 71111.04-05.
b. Findings
No findings of significance were identified.
.2 Complete Walkdown
a. Inspection Scope
On November 13, 2009, the inspectors performed a complete system alignment
inspection of the Unit 2 shutdown cooling system train B to verify the functional capability
of the system. The inspectors selected this system because it was considered both
safety-significant and risk-significant in the licensees probabilistic risk assessment. The
inspectors walked down the system to review mechanical and electrical equipment
line-ups, electrical power availability, system pressure and temperature indications,
component labeling, component lubrication, component and equipment cooling, hangers
and supports, operability of support systems, and to ensure that ancillary equipment or
debris did not interfere with equipment operation. The inspectors reviewed a sample of
past and outstanding work orders to determine whether any deficiencies significantly
affected the system function. In addition, the inspectors reviewed the corrective action
program database to ensure that system equipment alignment problems were being
identified and appropriately resolved. Specific documents reviewed during this
inspection are listed in the attachment.
These activities constitute completion of one complete system walkdown sample as
defined in Inspection Procedure 71111.04-05.
b. Findings
No findings of significance 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:
- October 26, 2009, Unit 3, condensate storage pump house and tunnel
- October 27, 2009, Unit 3, spray pond pump house
-7- Enclosure 2
- November 11, 2009, Unit 2, auxiliary building 40 foot and 77 foot elevations
- November 11, 2009, Unit 2, auxiliary building 88 foot and 140 foot elevations
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

control program for monitoring degradation of those systems that could be adversely
affected by boric acid corrosion. The inspectors reviewed the documentation associated
with the licensees boric acid corrosion control walkdown as specified in
Procedure 73DP-9ZC01, Boric Acid Corrosion Control Program, Revision 3, and
Procedure 70TI-9ZC01, Boric Acid Walkdown Leak Detection, Revision 9. The
inspectors also reviewed the visual records of the components and equipment. The
inspectors verified that the visual inspections emphasized locations where boric acid
leaks could cause degradation of safety-significant components. The inspectors also
verified that there were no engineering evaluations for those components where boric
acid was identified. The inspectors confirmed that the corrective actions performed for
evidence of boric acid leaks were consistent with requirements of the ASME Code.
Specific documents reviewed during this inspection are listed in the attachment.
These actions constitute completion of the requirements for Section 02.03.
b. Findings
No findings of significance were identified.
.4 Steam Generator Tube Inspection Activities (71111.08-02.04)
a. Inspection Scope
The inspectors assessed the in-situ screening criteria to assure consistency between
assumed nondestructive examination flaw sizing accuracy and data from the Electrical
- 11 - Enclosure 2
Power Research Institute (EPRI) examination technique specification sheets. No
conditions were identified that warranted in-situ pressure testing.
Due to the tube wear identified during the previous outage, a 100 percent review of all
tubes in both steam generators was performed during this outage. In addition, the
inspectors reviewed both the licensee site-validated and qualified acquisition and
analysis technique sheets used during this refueling outage and the qualifying EPRI
examination technique specification sheets to verify that the essential variables
regarding flaw sizing accuracy, tubing, equipment, technique, and analysis had been
identified and qualified through demonstration.
The inspection procedure specified comparing the estimated size and number of tube
flaws detected during the current outage against the previous outage operational
assessment predictions to assess the licensee's prediction capability. The number of
identified indications fell within the range of prediction and was consistent with
predictions from the vendor for the previous outage. No new damage mechanisms were
identified during this inspection. The licensee plugged ten tubes in steam generator 21
and four tubes in steam generator 22. A loose part, believed to be an eggcrate wedge,
has been identified in steam generator 21. It was identified in the previous outage, but
has migrated downward. The tubes in the vicinity were plugged and staked.
The inspection procedure specified confirmation that the steam generator tube eddy
current test scope and expansion criteria meet technical specification requirements,
EPRI guidelines, and commitments made to the NRC. The inspectors evaluated the
recommended steam generator tube eddy current test scope established by technical
specification requirements and the licensees degradation assessment report. The
inspectors compared the recommended test scope to the actual test scope and found
that the licensee had accounted for all known flaws and had, as a minimum, established
a test scope that met technical specification requirements, EPRI guidelines, and
commitments made to the NRC.
As mentioned above, the base scope inspection plan required 100 percent tube
inspection for this outage (2R15). The inspection scope for 2R15 included:
- 100 percent visual inspection of installed plugs
- Tubesheet secondary side foreign object search and retrieval
- 100 percent bobbin examination in both steam generators from tube end to tube end
- Plus point inspection of U-bends in rows 1 through 4
- Plus point inspection of special interest locations
Specific documents reviewed during this inspection are listed in the attachment.
These actions constitute completion of the requirements of Section 02.04.

The inspectors reviewed eight condition reports, which dealt with inservice inspection
activities and found the corrective actions were appropriate. The specific condition
reports reviewed are listed in the documents reviewed section. From this review the
inspectors concluded that the licensee has an appropriate threshold for entering issues
into the corrective action program and has procedures that direct a root cause evaluation
when necessary. The licensee also has an effective program for applying industry
operating experience. Specific documents reviewed during this inspection are listed in
the attachment.
These actions constitute completion of the requirements of Section 02.05.
b. Findings
No findings of significance were identified.
1R11 Licensed Operator Requalification Program (71111.11)
.1 Annual Inspection
a. Inspection Scope
The inspector reviewed the annual operating test results for 2009. Since this was the
first half of the biennial requalification cycle, the licensee was not required to administer a
written examination. These results were assessed to determine if they were consistent
with NUREG 1021, "Operator Licensing Examination Standards for Power Reactors,"
guidance and Manual Chapter 0609, Appendix I, "Operator Requalification Human
Performance Significance Determination Process," thresholds. This review included the
test results for a total of 20 crews (15 shift crews and 5 staff crews) composed of 70
senior reactor operators and 34 reactor operators. All individuals and crews passed all
portions of the operating test.
The inspector completed one sample.
b. Findings

resulted in valid or invalid automatic actuations of engineered safeguards systems and
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

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 two quarterly maintenance effectiveness
samples as defined in Inspection Procedure 71111.12-05.
b. Findings
No findings of significance were identified.
1R13 Maintenance Risk Assessments and Emergent Work Control (71111.13)
a. Inspection Scope
Risk Assessment and Management of Risk
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 from service for work:
- September 14, 2009 and October 19, 2009, Unit 1, emergent work risk
assessment associated with switchyard breaker 982
- October 22, 2009, Unit 3, excore control channel 1 out of service for emergent
work
- November 9 through 17, 2009, Unit 2, high pressure safety injection pump train B
removed from service for corrective maintenance concurrent with emergency
diesel generator train A unavailability during refuelling outage
- December 8, 2009, Unit 2, emergency diesel generator train A out of service for
planned maintenance
- December 11, 2009, Unit 2, main transformer C out of service for emergent
repairs of the neutral bushing
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)
- 15 - Enclosure 2
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 five maintenance risk assessments and
emergent work control inspection samples as defined in Inspection
Procedure 71111.13-05.
b. Findings
No findings of significance were identified.
1R15 Operability Evaluations (71111.15)
a. Inspection Scope
The inspectors reviewed the following issues:
- April 10, 2009, Units 1, 2, and 3, operability determination for lack of design basis
accident testing for containment coating
- September 28, 2009, Units 1, 2, and 3, operability determination for start-up

- November 11, 2009, Unit 2, essential cooling water heat exchanger A
circumferential cracks
- November 19, 2009, Units 1, 2 and 3, operability determination for radioactive
water storage tank degraded condition
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 UFSAR to
- 16 - Enclosure 2
the licensees 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 seven operability evaluation inspection samples
as defined in Inspection Procedure 71111.15-05.
b. Findings
Introduction. The inspectors identified a Green cited violation of 10 CFR Part 50,
Appendix B, Criterion V, "Instructions, Procedures, and Drawings," for the failure of
engineering personnel to establish adequate procedures to ensure evaluation and
approval of transient missile hazards that have an effect on the operability of the
essential spray ponds. Specifically, since January 15, 1997, civil engineering personnel
failed to develop an adequate procedure to verify missile density criteria are not
exceeded to ensure operability of the essential spray ponds during severe weather. This
issue was entered into the licensee's corrective action program as Condition
Report/Disposition Request (CRDR) 3397839.
Description. On October 27, 2009, the inspectors were performing walkdowns of the
Unit 2 essential spray ponds and observed a high concentration of potential tornado
borne missile hazards within 400 feet of the essential spray ponds. The potential missile
hazards included stacks of pallets, temporary light fixtures, stanchions, scaffolding,
temporary structures, and other miscellaneous materials. The inspectors then notified
the Unit 2 shift manager of the potentially nonconforming condition.
The following morning on October 28, 2009, the inspectors observed an even higher
concentration of potential missile hazards including approximately 40 pallets stacked in
the immediate vicinity of the Unit 2 essential spray ponds. The inspectors notified civil
engineering personnel who then conducted a walkdown of the essential spray ponds for
Unit 2. PVAR 3397505 documented the walkdown and noted numerous areas of
noncompliance with Specification 13-CN-0389, Installations Specification for the Control
of Potential Tornado Borne Missiles in Outside Areas, Revision 0. Later that day
operations personnel reviewed PVAR 3397505 and requested civil engineering to
perform an evaluation of the areas surrounding the Unit 1 and Unit 2 essential spray
ponds to support an operability determination/functional assessment.
On the morning of October 29, 2009, the inspectors observed that the stack of pallets
and other miscellaneous potential missile hazards still had not been relocated or
secured in accordance with Specification 13-CN-0389. The inspectors noted that civil
engineering personnel conducted their review to ensure compliance and utilized
Procedure 81DP-0ZY01, "Control of Potential Tornado Borne Missiles in the Outside
Areas," Revision 3. The engineering evaluation was documented in Component
Observation Report 09-9-011. The evaluation concluded that while an excessive
number of temporary structures caused certain zones to exceed the maximum
- 17 - Enclosure 2
allowable average missile density of 4 per 10,000 square feet, the overall density across
all zones surrounding the Unit 1 and Unit 2 essential spray ponds was less than the
maximum allowable density. Based on this evaluation, operations personnel performed
an functional determination and declared the essential spray ponds for Units 1 and 2
functional.
The inspectors analyzed the civil engineering evaluation and concluded it accurately
represented the potential missile hazard density at the time of the evaluation. However,
in response to PVAR 3397505, maintenance personnel removed potential missile
hazards from within 400 feet of the spray ponds the morning of October 29, 2009. The
evaluation civil engineering personnel conducted on the afternoon of October 29, 2009
did not include at least 30 additional pallets that were within 400 feet of the Unit 2
essential spray ponds that the inspectors had photographed the day before. When the
inspectors shared these photographs with civil engineering personnel, the additional
pallets were included in a second evaluation, which concluded the maximum allowable
density of 4 missiles per 10,000 square feet across all zones surrounding the Unit 2
essential spray ponds was exceeded. At the time, Unit 2 was defueled as part of
Refueling Outage U2R15 and the Unit 2 essential spray ponds were not required to be
operable per technical specifications. However, they were being credited for spent fuel
pool cooling and therefore required to be Functional as defined by Section 5.1 of
Procedure 40DP-9OP26 Operations PVAR Processing and Operability
Determination/Functional Assessment, Revision 26.
During their review, the inspectors also noted that UFSAR, Section 3.5.1.4, "Missiles
Generated by Natural Phenomena (Tornados)," stated, in part, that tornado missile
protection is not provided for the essential spray pond nozzles because the probability of
loss of the ultimate heat sink safety function has been demonstrated by probabilistic risk
assessment to be less than a median value of 10-7 per reactor year or a mean value of
10-6 per reactor year without missile protection. The licensee ensured the probabilistic
risk assessment numbers provided in UFSAR Section 3.5.1.4 were satisfied by giving
recommended missile densities in Calculation 13-NC-SP-201, "Spray Pond Tornado
Missile Damage Frequency," Revision 3. To ensure the missile densities given in
calculation 13-NC-SP-201 were not exceeded, civil engineering personnel perform
quarterly walkdowns of the essential spray ponds, and rely on ensuring the requirements
of Procedure 81DP-0ZY01 and Specification 13-CN-0389 are implemented to control
transient missile hazards.
During their review, the inspectors noted a previous noncited violation
(NCV 05000528/2008004-04, Failure to Provide an Adequate Procedure to Control
Essential Spray Pond Missile Hazards) in NRC integrated inspection report 2008004 for
a similar performance deficiency identified July 11, 2008. The inspectors reviewed
corrective actions associated with that violation detailed in adverse CRDR 3224028 to
determine why the licensee failed to restore compliance within a reasonable time. The
inspectors noted that the corrective actions to restore compliance included revising
Procedure 30DP-09MP01 Conduct of Maintenance to add a step instructing
maintenance personnel to secure potential missile hazards in accordance with
Procedure 81DP-0ZY01. The corrective actions also included reviews of Procedure
81DP-0ZY01 and Procedure 12DP-0MC45 Management of Contracts and Supplier
Personnel, in which engineering personnel concluded that these procedures adequately
addressed the control of potential missile hazards around the essential spray ponds.
- 18 - Enclosure 2
Prior to NCV 05000528/2008004-04, the inspectors noted a noncited violation (NCV
05000528; 529; 530/2007012-01, Failure to Implement the Operability Determination
process) in NRC supplemental 95003 inspection report 2007012 discussed a similar
performance deficiency regarding potential missile hazards around the essential spray
ponds. In this case the performance deficiency was the failure of operations personnel
to perform an operability determination for an unanalyzed condition involving a high
concentration of potential missile hazards around the essential spray ponds. The
corrective actions identified by the licensee for this noncited violation were to enhance
Procedure 81DP-0ZY01 to include guidance for engineering personnel. Specifically, civil
engineering personnel were to ensure the essential spray ponds were evaluated for
missile hazard density when maintenance activities involving potential missile hazards
occurred.
On January 30, 2009, as part of the licensees internal corrective actions for non-cited
violations associated with the 95003 inspection, the licensee reviewed the treatment of
potential missile hazards and concluded that Procedure 81DP-0ZY01 was inadequate
for controlling missile hazards around the essential spray ponds. The licensee initiated
CRDR 3280781 and conducted an apparent cause evaluation to investigate and correct
the ineffective control of tornado-borne missile hazards. The inspectors noted that
corrective actions called for in the apparent cause evaluation included assigning
ownership to the areas surrounding the spray ponds, revising Procedure 81DP-0ZY01,
developing a site wide training plan for missile hazard control, and creating
Specification 13-CN-0389 to provide additional guidance for all personnel on control of
potential missile hazards. As an interim corrective action, civil engineering personnel
conducted monthly walkdowns of the areas surrounding the essential spray ponds from
April through September 2009. The inspectors observed that Specification 13-CN-0389
was completed on September 30, 2009; however, the revisions to Procedure
81DP-0ZY01 and the site wide training plan are not scheduled to be completed until
January 15, 2010.
After conducting several interviews with civil engineering personnel and reviewing all of
the corrective actions to address the missile hazards since the 95003 inspection, the
inspectors concluded that the licensee did not restore compliance and provide an
adequate procedure to control essential spray pond missile hazards within a reasonable
time. The inspectors noted that even if all transient missile hazards were secured in
accordance with step 8.7.4 of Specification 13-CN-0389, there was still the potential for
missile hazards to accumulate to densities greater than the acceptable limits allowed per
calculation 13-NC-SP-201 in the time periods between quarterly walkdowns. The
inspectors also noted that the licensee failed to implement adequate interim corrective
actions after determining that Procedure 81DP-0ZY01 was inadequate. Following the
completion of Specification 13-CN-0389, the inspectors noted procedures governing
housekeeping and conduct of maintenance still referenced Procedure 81DP-0ZY01 to
address the control of potential missile hazards. The inspectors also noted that
Procedure AC-0241, "Maintenance Work Order Process and Control," Revision 0, did
not address potential missile hazards when developing maintenance work packages nor
did Procedure 12DP-0MC45 Management of Contracts and Supplier Personnel directly
address informing contractor personnel of procedures for controlling potential missile
hazards. Based on the inspectors observations from October 27 through October 29,
2009, it was evident that neither maintenance nor contractor personnel had been
adequately trained on the control of potential missile hazards per Specification
13-CN-0389. Furthermore, the inspectors noted that neither Specification 13-CN-0389
- 19 - Enclosure 2
nor Procedure 81DP-0ZY01 provided adequate guidance on exactly when an observed
concentration of potential missile hazards merits an operability determination or
functional assessment for the essential spray ponds.
Analysis. The performance deficiency associated with this finding was the failure of
engineering personnel to establish adequate maintenance procedures to ensure
evaluation and approval of transient missile hazards that have an effect on the
operability of the essential spray ponds. The finding is more than minor because it is
associated with the external factors attribute of the Mitigating Systems Cornerstone and
affects the cornerstone objective of ensuring the reliability of systems that respond to
initiating events to prevent undesirable consequences. Using Manual Chapter 0609.04,
"Phase 1 - Initial Screening and Characterization of Findings," the finding was
determined to have very low safety significance (Green) because the finding did not
result in a loss of system safety function, an actual loss of safety function of a single train
for greater than its technical specification allowed outage time, or screen as potentially
risk significant due to a seismic, flooding, or severe weather initiating event. This finding
has a crosscutting aspect in the area of problem identification and resolution associated
with the corrective action program because appropriate corrective actions were not
taken to address safety issues and adverse trends in a timely manner, commensurate
with their safety significance and complexity P.1(d).
Enforcement. Title 10 CFR Part 50, Appendix B, Criterion V, "Instructions, Procedures
and Drawings," requires that activities affecting quality shall be prescribed by
instructions, procedures, or drawings, and shall be accomplished in accordance with
those instructions, procedures, and drawings. UFSAR, Section 3.5.1.4, "Missiles
Generated by Natural Phenomena (Tornados)," provided probabilistic risk assessment
criteria to ensure essential spray pond operability. Calculation 13-NC-SP-201 provided
missile density requirements to ensure the probabilistic risk assessment numbers in
UFSAR, Section 3.5.1.4 are met. Procedure 81DP-0ZY01 and Specification
13-CN-0389 implemented the control of transient missile hazards to ensure the missile
density requirements of calculation 13-NC-SP-201 are met. Contrary to the above,
between January 15, 1997, and October 27, 2009, the licensee failed to provide
adequate procedures to ensure evaluation and approval of transient missile hazards that
have an effect on the operability of the essential spray ponds. Specifically, civil
engineering personnel failed to develop an adequate procedure to verify missile density
criteria are not exceeded. This finding was of very low safety significance and was
entered into the licensee's corrective action program as PVAR 3397839. Due to the
licensees failure to restore compliance from the previous noncited violation NCV
05000528/2008004-04 within a reasonable time, this violation is being cited in a Notice
of Violation consistent with Section VI.A of the NRC Enforcement Policy: VIO 05000528;
05000529;05000530/2009005-01 Failure to Establish Adequate Procedures to Control
Potential Tornado Borne Missile Hazards Near the Essential Spray Ponds.
1R18 Plant Modifications (71111.18)

the safety functions of important safety systems were not degraded:
- 20 - Enclosure 2
- October 13, 2009, Unit 1, installation of jumpers for defective heated junction
thermocouples on the reactor vessel level monitoring system, train A and train B
The inspectors reviewed the temporary modification and the associated safety
evaluation screening against the system design bases documentation, including the
UFSAR and the technical specifications, and verified that the modification did not
adversely affect the system operability/availability. The inspectors also verified that the
installation was 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 effects on mitigating strategies during
implementation of emergency operating procedures.
These activities constitute completion of one temporary plant modification inspection

- Licensee identification and resolution of problems related to maintenance outage
activities.
These activities constitute completion of one refueling and one other outage inspection
samples as defined in Inspection Procedure 71111.20-05.
b. Findings
Introduction. A Green self-revealing noncited violation of Technical Specification 5.4.1.a,
Procedures, was identified for the failure of maintenance personnel to maintain
containment closure capability as required by Procedure 70DP-0RA01, Shutdown Risk
Assessments. Specifically, on October 8, 2009 maintenance personnel designated for
emergency closure of the containment equipment hatch left containment to attend a
safety briefing for more than 4-hours before they returned to perform their required
duties.
.
Description. Palo Verde, Unit 2, shutdown and commenced a refueling outage on
October 1, 2009. On October 7, 2009, the containment equipment hatch was opened to
allow for moving of large equipment and components in and out of containment.
Procedure 70DP-0RA01, Shutdown Risk Assessments, required that a trained
containment closure team be stationed at the equipment hatch to ensure the capability
to isolate containment within the RCS time to boil is maintained. The procedure credited
maintenance personnels ability to close the equipment hatch within 25 minutes.
On October 8, 2009, at approximately 8 p.m., maintenance crews working in
containment dropped a reactor vessel guide pin. Due to this event, at approximately
10:30 p.m., all maintenance personnel in containment were directed to stop work
pending a safety briefing to discuss the dropped guide pin. At 12:30 a.m. on
October 9, 2009, the team responsible for containment closure left containment to await
the safety briefing in a trailer near Unit 1. After the safety briefing, at 4:30 a.m., the
containment closure team returned to containment. Later that morning, at approximately
6 a.m., the inspectors discussed the event with operations personnel and determined
that while the containment equipment hatch closure team was removed from
containment, the ability to close the equipment hatch and isolate containment if needed
during a loss of shutdown cooling event was in question. During their review, the
inspectors reviewed logs and personal statements as well as reviewed timed simulations
and determined that the licensee would not have been able to return to containment and
close the equipment hatch within 30 minutes contrary to the requirements of Procedure
70DP-0RA01, Shutdown Risk Assessments.
Analysis. The performance deficiency associated with this finding involved the failure of
maintenance personnel to follow the requirements of Procedure 70DP-0RA01,
Shutdown Risk Assessments, to ensure a containment closure team was in
containment and capable of closing the containment equipment hatch within 30 minutes.
The finding was more than minor because it affected the configuration control attribute of
the Barrier Integrity Cornerstone, and affected the cornerstone objective to provide
reasonable assurance that physical design barriers protect the public from radionuclide
releases caused by accidents or events. Using Manual Chapter 0609.04, Phase 1 -
Initial Screening and Characterization of Findings," the finding was determined to
represent an actual open pathway in the physical integrity of reactor containment, and
required evaluation using Manual Chapter 0609, Appendix H, Containment Integrity
- 24 - Enclosure 2
Significance Determination Process. The finding was determined to be a Type B finding
because it affected only large early release frequency, not core damage frequency, at
shutdown. Using Manual Chapter 0609, Appendix H, Table 6.3, Phase 1 Screening-
Type B Findings at Shutdown, the inspectors determined that a Phase 2 evaluation was
required. The inspectors performed a Phase 2 analysis using Table 6.4, Phase 2 Risk
Significance-Type B Findings at Shutdown, and made the following determinations:
The plant was determined to be in POS 2E which represents cold shutdown with
the RCS vented, steam generators not available, and within 8 days of shutdown
The finding existed for less than 8-hours
There was mitigation equipment out of service
The inspectors reviewed Table 6.8, PWRs With In-Depth Shutdown Mitigation
Capability, and determined that during the time that Palo Verde lost the capability to
close the equipment hatch in less than 30 minutes, there was an in-depth shutdown
mitigation capability. The senior reactor analyst reviewed the analysis and determined
that that the finding has very low safety significance (Green). This was based on the
short time period that the condition existed (approximately 4-hours), the low probability
of a loss of cooling event during this period (two fully-functional trains were available),
and the fact that the time it would have taken to close the hatch in the worst case (30-
minutes) was well less than the time until the core would have become uncovered
(greater than 60-minutes), indicating that the probability of failing to close the equipment
hatch prior to fuel damage was very low. This finding was determined to have a cross
cutting aspect in the area of human performance associated with work control because
the licensee failed to appropriately coordinate work activities by incorporating actions to
address plant conditions that may affect work activities H.3(b).
Enforcement. Palo Verde Technical Specification 5.4.1.a, Procedures, requires that
written procedures be established, implemented, and maintained covering the activities
specified in Regulatory Guide 1.33, Revision 2, Appendix A, dated February 1978.
Regulatory Guide 1.33, Appendix A, Section 3.f.(1), requires, in part, that during
shutdown operations, procedures shall be prepared for maintaining containment
integrity. Procedure 70DP-0RA01, Shutdown Risk Assessments, Revision 32,
required, in part, that a trained containment closure team shall be stationed inside
containment and shall be capable of closing the containment equipment hatch within the
RCS time to boil (30 minutes). Contrary to the above, on October 8, 2009, maintenance
personnel dedicated for the emergency closure of the containment equipment hatch left
containment and were unable to perform their containment equipment hatch closure
function within the reactor coolant system time to boil. Because the finding is of very low
safety significance and has been entered into the licenses corrective action program as
PVAR 3389284 this violation is being treated as a noncited violation consistent with
section VI.A of the NRC Enforcement Policy: NCV 05000529/2009005-02 Failure to
Maintain Containment Closure Capability.

1R22 Surveillance Testing (71111.22)
a. Inspection Scope
The inspectors reviewed the UFSAR, procedure requirements, and technical
specifications to ensure that the three surveillance activities listed below demonstrated
that the systems, structures, and/or components tested were capable of performing their
intended safety functions. The inspectors either witnessed or reviewed test data to verify
that the significant surveillance test attributes were adequate to address the following:
- Preconditioning
- Evaluation of testing impact on the plant
- Acceptance criteria
- Test equipment
- Procedures
- Jumper/lifted lead controls
- Test data
- Testing frequency and method demonstrated technical specification operability
- Test equipment removal

- Engineering evaluations, root causes, and bases for returning tested systems,
structures, and components not meeting the test acceptance criteria were correct
- Reference setting data
- Annunciators and alarms setpoints
The inspectors also verified that licensee personnel identified and implemented any
needed corrective actions associated with the surveillance testing.
- October 23, 2009, Unit 2, essential spray pond pumps train B - comprehensive
and inservice pump test
- October 30, 2009, Unit 1, safety injection system train B valve stroke tests
- December 1, 2009, Unit 2, low power physics testing
Specific documents reviewed during this inspection are listed in the attachment.

2. RADIATION SAFETY
Cornerstone: Occupational Radiation Safety
2OS1 Access Control to Radiologically Significant Areas (71121.01)
a. Inspection Scope
This area was inspected to assess the licensee=s performance in implementing physical
and administrative controls for airborne radioactivity areas, radiation areas, high
radiation areas, and worker adherence to these controls with respect to the Unit 2
refueling outage and reactor vessel head replacement activities. The inspectors used
the requirements in 10 CFR Part 20, the technical specifications, and the licensee=s
procedures required by technical specifications as criteria for determining compliance.
During the inspection, the inspectors interviewed the radiation protection manager,
radiation protection supervisors, and radiation workers. The inspectors performed
independent radiation dose rate measurements and reviewed the following items:
- Controls (surveys, posting, and barricades) of five radiation, high radiation, and
potential airborne radioactivity areas
- Radiation exposure permit, procedure, and engineering controls and air sampler
locations
- Conformity of electronic personal dosimeter alarm set points with survey
indications and plant policy; workers= knowledge of required actions when their
electronic personnel dosimeter noticeably malfunctions or alarms
- Adequacy of the licensees internal dose assessment for any actual internal
exposure greater than 50 mrem committed effective dose equivalent
- Barrier integrity and performance of engineering controls in 4 potential airborne
radioactivity areas
- Radiation exposure permit briefings and worker instructions
- Adequacy of radiological controls such as required surveys, radiation protection
job coverage, and contamination controls during job performance
- Dosimetry placement in high radiation work areas with significant dose rate
gradients
- Controls for special areas that have the potential to become very high radiation
areas during certain plant operations
- 27 - Enclosure 2
- Posting and locking of entrances to all accessible high dose rate - high radiation
areas and very high radiation areas
- Radiation worker and radiation protection technician performance with respect to
radiation protection work requirements
Specific documents reviewed during this inspection are listed in the attachment.
These activities constitute completion of three of the required 21 samples as defined in
Inspection Procedure 71121.01-05. The remaining samples in Inspection Procedure
71121.01 were previously documented in NRC Integrated Inspection Report 05000528;
05000529; 05000530/2009003.
b. Findings
Introduction. A self-revealing Green noncited violation of Technical Specification 5.7.1,
High Radiation Areas, was identified for the failure of radiological protection personnel
to perform a prejob briefing to ensure workers are aware of radiological conditions in a
high radiation area as required by the radiation exposure permit. Specifically, on
October 20, 2009, nine contract workers were preparing to install an anticontamination
sock over the Unit 2 old reactor vessel head, signed onto a radiation exposure permit
which allowed access to a high radiation area but failed to receive a brief on the local
dose rates surrounding the reactor vessel head by the job coverage radiation protection
technician.
Description. On October 20, 2009, nine contractor workers were preparing to install an
anticontamination sock over the Unit 2 old reactor vessel head. The workers signed
onto a radiation exposure permit which allowed access to a high radiation area (the
entire area around the vessel head was being controlled as a high radiation area). The
contractors entered the radiological controlled area, dressed out, and entered
containment after receiving a briefing from the radiation protection technician on
containment radiation levels. However, they did not receive a prejob brief on dose rates
from radiation protection technician covering the reactor vessel head job as required by
the radiation exposure permit. They proceeded to cover the vessel head, but one
worker received an 85 mr/hr electronic dosimeter rate alarm. Based on the alarm
investigation, it was revealed that none of the nine workers had received the required
prejob briefing from a radiation protection technician making them aware of the 100- to
140-mr/hr dose rate levels in the high radiation area. Trip tickets had not been signed by
the radiation protection technician covering the job; therefore, they were not authorized
to enter the high radiation area. The licensees immediate corrective action was to
counsel the contractor group and radiation protection staff on prejob briefing
expectations.
Analysis. The performance deficiency associated with this finding was the failure of the
licensee to comply with high radiation area entry requirements and perform radiation
exposure permit prejob briefs. The finding was more than minor because it was
associated with the exposure control attribute of the Occupational Radiation Safety
Cornerstone and affected the cornerstone objective to properly control access to a high
radiation area and had the potential to increase personnel dose. Using Manual Chapter
0609, Appendix C, Occupational Radiation Safety Significance Determination Process,
- 28 - Enclosure 2
the finding was determined to have very low safety significance (Green) because it was
not associated with as low as reasonably achievable, there was no overexposure,
there was no substantial potential for an overexposure; and the ability to assess dose
was not compromised. This finding has a crosscutting aspect in the area of human
performance associated with work practices because the licensees radiation protection
staff failed to communicate expectations to contract personnel H.4(b).
Enforcement. Technical Specification 5.7.1, High Radiation Areas, requires that entry
into high radiation areas shall be controlled by requiring issuance of a radiation exposure
permit. Contrary to the above, on October 20, 2009, nine contractors entered a high
radiation area not in accordance with the radiation exposure permit. Specifically, they
entered the high radiation area without receiving a pre-briefing and without being made
aware of the dose rates in the area. This failure to meet high radiation area entry
requirements is of very low safety significance and has been entered into the licensees
corrective action program as CRDR 3394172. This violation is being treated as a
noncited, consistent with Section VI.A of the NRC Enforcement Policy: NCV
05000529/2009005-03, Failure to Comply with High Radiation Area Entry
Requirements.
2OS2 ALARA Planning and Controls (71121.02)
a. Inspection Scope
The inspectors assessed licensee performance with respect to maintaining individual
and collective radiation exposures As Low As Reasonably Achievable (ALARA). The
inspectors used the requirements in 10 CFR Part 20 and the licensees procedures
required by technical specifications as criteria for determining compliance. The
inspectors interviewed licensee personnel and reviewed:
- Current 3-year rolling average collective exposure
- Site-specific trends in collective exposures, plant historical data, and source-term
measurements
- Site-specific ALARA procedures
- Five work activities of highest exposure significance completed during the last
outage
- ALARA work activity evaluations, exposure estimates, and exposure mitigation
requirements
- Intended versus actual work activity doses and the reasons for any
inconsistencies
- Interfaces between operations, radiation protection, maintenance, maintenance
planning, scheduling and engineering groups
- Integration of ALARA requirements into work procedure and radiation exposure
permit documents
- 29 - Enclosure 2
- Person-hour estimates provided by maintenance planning and other groups to
the radiation protection group with the actual work activity time requirements
- Shielding requests and dose/benefit analyses
- Dose rate reduction activities in work planning
- Post-job (work activity) reviews
- Assumptions and basis for the current annual collective exposure estimate, the
methodology for estimating work activity exposures, the intended dose outcome,
and the accuracy of dose rate and man-hour estimates
- Method for adjusting exposure estimates, or replanning work, when unexpected
changes in scope or emergent work were encountered
- Exposure tracking system
- Use of engineering controls to achieve dose reductions and dose reduction
benefits afforded by shielding
- First-line job supervisors contribution to ensuring work activities are conducted in
a dose efficient manner
- Records detailing the historical trends and current status of tracked plant source
terms and contingency plans for expected changes in the source term due to
changes in plant fuel performance issues or changes in plant primary chemistry
- Source-term control strategy or justifications for not pursuing such exposure
reduction initiatives
- Specific sources identified by the licensee for exposure reduction actions,
priorities established for these actions, and results achieved since the last
refueling cycle
- Radiation worker and radiation protection technician performance during work
activities in radiation areas, airborne radioactivity areas, or high radiation areas
- Self-assessments, audits, and special reports related to the ALARA program
since the last inspection
- Resolution through the corrective action process of problems identified through
postjob reviews and post-outage ALARA report critiques
- Corrective action documents related to the ALARA program and follow-up
activities, such as initial problem identification, characterization, and tracking
- Effectiveness of self-assessment activities with respect to identifying and
addressing repetitive deficiencies or significant individual deficiencies
Specific documents reviewed during this inspection are listed in the attachment.
- 30 - Enclosure 2
The inspectors completed 13 of the required 15 samples and 12 of the optional samples
as defined in Inspection Procedure 71121.02-05.
b. Findings
Introduction. The inspectors identified a noncited violation of 10 CFR Part 50.71,
Maintenance of Records, because the licensee failed to update their UFSAR with
submittals that include the effects of a change made to the facility. Specifically, the
licensee built the old steam generator storage facility on the owner controlled area for
long-term radwaste storage of six decommissioned steam generators and three reactor
vessel heads and failed to update the UFSAR to include these changes to the facility
and all safety analyses and evaluations performed.
Description. While inspecting the licensees Unit 2 reactor head replacement activities
related to solid radwaste management and storage, the inspectors identified that the
decommissioned steam generator and reactor vessel head storage facility was not
described in Chapters 11 and 12 of the UFSAR. Currently, the UFSAR, Chapters 11
and 12, Sections 11.4, Solid Waste Management, and 12.2.1.7, "Stored Radioactivity,"
describes facilities for the interim storage of radioactive material such as the dry active
waste processing and storage facility and the low level radioactive material storage
facility. However, the old steam generator storage facility is not described in the
UFSAR. Section 12.2.1.7 of the UFSAR also describes that principal sources of
radioactivity not enclosed by plant structures are the independent spent fuel storage
installation, the refueling water tank, the holdup tank, the reactor makeup water tank,
and the condensate storage tank.
The licensee is committed to Regulatory Guide 1.70, Standard, Format, and Content of
a Safety Analysis Report, Revision 3, which describes the content of Chapter 11,
Section 11.4, Solid Waste Management System. Regulatory Guide 1.70 states, in part,
that this section should describe the capabilities of the plant to control, collect, handle,
process, package, and temporarily store prior to shipment wet and dry solid radioactive
waste generated as a result of normal operation, including anticipated operational
occurrences. Regulatory Guide 1.70 also describes Chapter 12 of a safety analysis
report stating, in part, that it should provide information on methods for radiation
protection, estimated occupational radiation exposures to personnel during normal
operation and anticipated operational occurrences including radioactive material
handling, processing, use, and storage. Section 12.2.1, Radiation Contained Sources,
is the basis for the radiation protection design that should be described in the manner
needed as input to the shield design calculations. Those sources that are contained in
equipment like the radioactive waste management systems should be described. The
source location in the plant should be specified so that all important sources of
radioactivity can be located on plant layout drawings. Also, the safety analysis report
should provide a listing of isotope, quantity, form, and use of all sources that exceed 100
millicuries.
The old steam generator storage facility has been in use since 2003 and contains six
decommissioned steam generators from Units 1, 2, and 3 and now the Unit 2 reactor
vessel head. Each old steam generator contains 48.1 curies of Co-60 and the reactor
head contains 7.5 curies Co-60. Thus, the old steam generator storage facility contains
296 curies, a significant source of radioactivity, not described in the licensees UFSAR.
- 31 - Enclosure 2
Analysis. The performance deficiency associated with this finding was failure of the
licensee to update the UFSAR to reflect changes made to the facility. This issue was
dispositioned using traditional enforcement because it had the potential for impacting the
NRCs ability to perform its regulatory function. The finding is more than minor because
it has a material impact on licensed activities in that the six decommissioned steam
generators and the Unit 2 reactor vessel head, with a significant radioactive source term,
have been relocated from the plant radiological controlled area to the owner controlled
area. In addition, the radwaste management program has been affected because the
licensee determined that this low-level radwaste facility will store these large
components until the site is decommissioned. The finding is characterized as a Severity
Level IV, noncited violation in accordance with NRC Enforcement Policy, Supplement I,
and was treated as a noncited violation consistent with Section VI.A.1 of the NRC
Enforcement Policy. This finding was reviewed for crosscutting aspects and none were
identified because the performance deficiency is not indicative of current performance.
Enforcement. Title 10 CFR 50.71, Maintenance of Records, requires, in part, that
licensees periodically update their UFSAR with submittals that include the effects of all
changes made in the facility or procedures as described in the UFSAR, and all safety
analyses and evaluations performed by the licensee in support of conclusions that
changes did not require a license amendment in accordance with 10 CFR 50.59(c)(2).
Contrary to this requirement, from 2003 through the present, the licensee made changes
to the facility and procedures as described in the UFSAR performed safety analyses and
evaluations in support of these changes, but failed to update the UFSAR to include
these changes. Specifically, the licensee built the old steam generator storage facility
for storing radioactive waste (six replaced steam generators and three reactor vessel
heads) on the owner controlled site for long-term storage until decommissioning.
Because the finding was of very low safety significance and has been entered into
licensee corrective action program as CRDR 3398042, this violation is being treated as
an NCV, consistent with Section VI.A.1 of the NRC Enforcement Policy: NCV 05000528;
05000529;05000530/2009005-04, Failure to Periodically Update the UFSAR.

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 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 of significance 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.
- 35 - Enclosure 2
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 of significance were identified.
.3 Selected Issue Follow-up Inspection
a. Inspection Scope
In addition to the routine review, the inspectors selected the below listed issue for a
more in-depth review. The inspectors considered the following during the review of the
licensee's actions: (1) complete and accurate identification of the problem in a timely
manner; (2) evaluation and disposition of operability/reportability issues;
(3) consideration of extent of condition, generic implications, common cause, and
previous occurrences; (4) classification and prioritization of the resolution of the problem;
(5) identification of root and contributing causes of the problem; (6) identification of

resolution sample as defined in Inspection Procedure 71152-05.
b. Findings
No findings of significance were identified.
.4 Semi-Annual Trend Review
a. Inspection Scope
The inspectors performed a review of the licensees corrective action program and
associated documents to identify trends that could indicate the existence of a more
significant safety issue. The inspectors focused their review on repetitive equipment
issues, but also considered the results of daily corrective action item screening
discussed in Section 4OA2.2, above, licensee trending efforts, and licensee human
performance results. The inspectors nominally considered the 6-month period of July 1
through December 31, 2009, although some examples expanded beyond those dates
where the scope of the trend warranted.
The inspectors also included issues documented outside the normal corrective action
program in major equipment problem lists, repetitive and/or rework maintenance lists,
departmental problem/challenges lists, system health reports, quality assurance
audit/surveillance reports, self-assessment reports, and maintenance rule assessments.
The inspectors compared and contrasted their results with the results contained in the
licensees corrective action program trending reports. Corrective actions associated with
- 36 - Enclosure 2
a sample of the issues identified in the licensees trending reports were reviewed for
adequacy.
These activities constitute completion of one single semi-annual trend review inspection
sample as defined in Inspection Procedure 71152-05.
b. Findings
No findings of significance were identified.
.5 In-depth Review of Operator Workarounds
a. Inspection Scope
The inspectors conducted a cumulative review of operator workarounds for Units 1, 2,
and 3 and assessed the effectiveness of the operator workaround program to verify that
the licensee is: (1) identifying operator workaround problems at an appropriate
threshold; (2) entering them into the CAP; and (3) identifying and implementing
appropriate corrective actions. The review included walkdowns of the control room
panels, interviews with licensed operators and reviews of the control room discrepancies
log, the lit annunciators log, the operator workaround list, the operator burdens list,
operations concerns list, the operator challenges tracking system, and site performance
metrics for operator burdens, lit annunciators, control room discrepancies, and long term
tagouts.
These activities constitute completion of one operator workaround program inspection
sample as defined in Inspection Procedure 71152-05.
b. Findings and Observations
No findings of significance were identified.
4OA3 Event Follow-up (71153)

actions to: (1) provide input in determining the appropriate agency response in
accordance with Management Directive 8.3, NRC Incident Investigation Program;
(2) evaluate licensee actions; and (3) confirm that the licensee properly classified the
event in accordance with emergency action level procedures and made timely
notifications to NRC and state/governments, as required.
- December 3, 2009, Unit 3, manual reactor trip from 100 percent power on a loss
of instrument air to containment
- December 10, 2009, Unit 2, downpower to support emergent repairs on the main
transformer train C neutral bushing
- 37 - Enclosure 2
Specific documents reviewed during this inspection are listed in the attachment.
These activities constitute completion of two samples as defined in Inspection
Procedure 71153-05.
b. Findings
Introduction. A Green self-revealing noncited violation of 10 CFR Part 50, Appendix B,
Criterion V, "Instructions, Procedures, and Drawings," was identified for the failure of
operations personnel to adequately establish and implement procedures associated with
a loss of instrument air to containment. Specifically, on December 3, 2009, the alarm
response and abnormal operating procedures available to the Unit 3 control room
operating staff were inadequate to effectively diagnose and mitigate a loss of instrument
air to containment.
Description. On December 3, 2009, Unit 3 was operating at full power. At
approximately 3:20 a.m. a ground alarm was received for the 125 Vdc electrical bus
E-PKA-M41. The control room crew entered panel B01A alarm response Procedure
43AL-3RK1A and dispatched an area operator to the 125 Vdc electrical bus in question.
At approximately 3:29 a.m. the area operator reset the ground alarm. At 3:39 a.m., a
high pressure alarm was received for the reactor coolant pump control bleed-off and the
crew recognized that control bleed-off isolation to the volume control tank valve
CHA-UV-506 position was intermediate and subsequently closed approximately one
minute later. The crew determined that the control bleed-off would be redirected to the
reactor drain tank via the system relief valve. The crew then entered panel B03A alarm
response Procedure 40AL-9RK3A to address the control bleed-off high pressure
condition. At approximately 3:48 a.m. a high level alarm was received for the reactor
drain tank level being greater than 75 percent, and at 3:54 a.m., a reactor drain tank high
pressure alarm was received. During an attempt to pump down the reactor drain tank
the crew discovered that valve CHA-UV-560, the reactor drain tank isolation inside
containment, was closed and would not reopen. At approximately 4:05 a.m., the crew
identified Valve IAA-UV-002, the isolation for instrument air to the containment, was
without indication and diagnosed a loss of instrument air to the containment.
The crew entered Procedure 40AO-9ZZ06, Loss of Instrument Air, and manually
tripped the reactor at 4:31 a.m. and secured all four reactor coolant pumps at 4:32 a.m.
Control bleed-off was isolated from the reactor coolant pumps at 4:34 a.m. The crew
entered Procedure 40EP-9EO07, Loss of Offsite Power/Loss of Forced Circulation, at
4:41 a.m. due to the loss of forced circulation when all the reactor coolant pumps were
secured. The decision to trip the reactor and secure all the reactor coolant pumps and
their associated control bleed-off was based on the desire to terminate the addition of
reactor coolant to the reactor drain tank. This would prevent rupturing the reactor drain
tank blow out disc. It was subsequently determined that the source of the previous
ground was a short circuit in the solenoid operator for IAA-UV-002. The short circuit is
believed to have cleared when the fuse in the circuit blew, causing a loss of power to
valve IAA-UV-002 resulting in the valve closing. A loss of instrument air to the
containment resulted when valve IAA-UV-002 closed.
Alarm response Procedure 43AL-3RK1A, 125V 1E CC M41 CHGR A/AC PNL D21
TRBL, addressed the ground indication received at 3:20 a.m. This procedure
implemented ground isolation steps but did not reference specific loads on panel
- 38 - Enclosure 2
PKA-M41. In addition, since the ground cleared and was subsequently reset when the
in-line fuse blew, no attempt to identify the source of the ground was made. Alarm
response Procedure 40AL-9RK3A, RCP SEAL SYS TRBL, entered at 3:39 a.m.,
directed determining the position of control bleed-off isolation valves CHB-UV-505 and
CHA-UV-506 and to reopen if closed. Alarm response Procedure 40AL-9RK3A,
RCP CONT BLEED-OFF PRESS HI-HI, also provided direction to determine if these
valve changed position and to reopen if closed, and directed investigating the cause of
their closure. The inspectors noted neither Procedure referenced a loss of instrument air
as a potential cause for their closure. At 3:48 a.m., alarm response Procedure 40AL-
9RK3A, REAC DRN LOOP TRBL, was entered for the reactor drain tank level of
greater than 75 percent. The crew recognized that the associated containment isolation
valve CHA-UV-560 was closed but did not associate its closure to a loss of instrument
air. At 4:05 a.m. a control room operator observed IAA-UV-002 without indication and
the loss of instrument air to the containment was subsequently diagnosed.
Procedure 40AO-9ZZ06, Loss of Instrument Air, provided guidance to reopen
IAA-UV-002 if instrument air is lost to the containment. Step 4 of this procedure
provided direction to perform Appendix J, Aligning N2 to the CTMT Instrument Air
Header, if IAA-UV-002 cannot be reopened. Step 7 of Procedure 40AO-9ZZ06 directed
the crew to perform Appendix A, Expected Component Failure as System Pressure
Drops. This appendix, page 11 of 36, indicated that the containment isolation valves for
the reactor coolant pump bleed-off to the volume control tank will close when
containment instrument air pressure drops to between 38 psig and 48 psig.
During their review, the inspectors noted this procedure directed these valves to be
manually opened if the reactor drain tank level is greater than 75 percent and the
containment is accessible. The reactor drain tank outlet isolation valves close in this
same pressure band. The inspectors also noted Procedure 40AO-9ZZ06, Appendix A,
was organized by component failures as overall instrument air header pressure drops
from the normal value but it did not differentiate containment instrument air header
pressure from the system instrument air header pressure. In addition, Appendix A did
not prioritize relative importance of each component failure nor did the procedure
address time constraints or industrial safety concerns for containment entries. The
appendix did not offer alternate strategies if the air operated valves cannot be reopened
in a timely manner. In addition, the inspectors noted Appendix J required resources for
a containment entry to restore instrument air header pressure inside containment. The
body of Procedure 40AO-9ZZ06, Loss of Instrument Air, did not prioritize actions
should the resources for containment entries be limited. With no success path provided
by existing procedures, the control room supervisor decided to take the unit off line, trip
the reactor coolant pumps, and isolate control bleed-off. The inspectors also noted that
removing the reactor coolant pumps from service and isolating control bleed-off were not
directed in the loss of instrument air abnormal operating procedure.
Analysis. The performance deficiency associated with this finding involved the failure of
operations personnel to adequately establish and implement abnormal operating
procedures associated with a loss of instrument air to the containment. The finding is
greater than minor because it is associated with the procedure quality attribute of the
Initiating Events Cornerstone and affects the cornerstone objective of limiting the
likelihood of those events that upset plant stability and challenge critical safety functions
during shutdown as well as power operations. Using the Manual Chapter 0609,
"Significance Determination Process," Phase 1 Worksheets, the finding was determined
- 39 - Enclosure 2
to have very low safety significance (Green) because the finding did not contribute to
both the likelihood of a reactor trip and the likelihood that mitigation equipment or
functions will not be available. This finding has a crosscutting aspect in the area of
problem identification and resolution associated with the corrective action program
because the licensee failed to implement the corrective action program with a low
threshold for identifying issues P.1(a).
Enforcement. 10 CFR Part 50, Appendix B, Criterion V, "Instructions, Procedures, and
Drawings," states, in part, that activities affecting quality shall be prescribed by
documented instructions, procedures, or drawings, of a type appropriate to the
circumstances and shall be accomplished in accordance with these instructions,
procedures, or drawings. Contrary to the above, procedures used to respond to the loss
of instrument air to the containment on December 3, 2009 were inadequate to effectively
diagnose and mitigate the off normal event. However, because the finding is of very low
safety significance and has been entered into the licensee's corrective action program as
PVAR 3411138 and CRDR 3411457, this violation is being treated as an NCV consistent
with Section VI.A of the NRC Enforcement Policy: NCV 05000528; 05000529;05000530/2009005-05, Inadequate Procedures to Diagnose and Mitigate a Loss of
Instrument Air to the Containment.
