Subject: COOPER NUCLEAR STATION - NRC INTEGRATED INSPECTION REPORT | |||
NUMBER 05000298/2011002 AND NOTICE OF VIOLATION | |||
Dear Mr. OGrady: | |||
On March 24, 2011, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection | |||
at your Cooper Nuclear Station. The enclosed integrated inspection report documents the | |||
inspection findings, which were discussed on March 29, 2011, with you 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 identified an issue that was evaluated | |||
under the risk significance determination process as having very low safety significance | |||
(Green). The NRC has also determined that a violation is associated with this issue. | |||
This violation was evaluated in accordance with the NRC Enforcement Policy. The current | |||
Enforcement Policy is included on the NRC's Web site at | |||
(http://www.nrc.gov/about-nrc/regulatory/enforcement/enforce-pol.html). | |||
The violation is cited in the enclosed Notice of Violation (Notice) and the circumstances | |||
surrounding it are described in detail in the subject inspection report. The violation involved the | |||
failure to appropriately assess and manage the risk associated with planned maintenance | |||
activities. The violation is being cited in the Notice because the licensee failed to restore | |||
compliance with NRC requirements within a reasonable time after violations were identified in | |||
Inspection Reports 05000298/2009005, 2010002, and 2010005. This is consistent with the | |||
NRC Enforcement Policy; Section 2.3.2, which states, in part, that a cited violation will be | |||

NRC-Identified Findings and Self-Revealing Findings | |||
Cornerstone: Initiating Events | |||
* | |||
Green. The inspectors identified a cited violation of 10 CFR 50.65(a)(4), | |||
Requirements for Monitoring the Effectiveness of Maintenance at Nuclear Power | |||
Plants, for the failure of work control and operations personnel to adequately | |||
assess and manage the increase in risk associated with maintenance activities. | |||
Specifically, on February 17, 2011, work control and operations personnel failed | |||
to adequately assess and manage the increase in risk associated with | |||
maintenance activities involving the use of heavy equipment in or near the | |||
electrical switchyard and offsite power components. Due to the licensees failure | |||
to restore compliance from the previous NCV 050000298/2008005-02 and other | |||
subsequent violations within a reasonable time after the violations were | |||
identified, this violation is being cited in a Notice of Violation consistent with | |||
Section 2.3.2 of the NRC Enforcement Policy. This finding was entered into the | |||
licensees corrective action program as condition reports CR-CNS-2010-09146, | |||
CR-CNS-2008-08645 and CR-CNS-2009-03714. | |||
The performance deficiency associated with this finding involved the licensees | |||
failure to adequately assess and manage the risk of planned maintenance | |||
activities. This finding is greater than minor because it affected the protection | |||
against external factors attribute of the Initiating Events Cornerstone, and directly | |||
affected the cornerstone objective to limit the likelihood of those events that | |||
upset plant stability and challenge critical safety functions during shutdown as | |||
well as power operations. The inspectors determined that Manual Chapter 0609, | |||
Appendix K, Maintenance Risk Assessment and Risk Management Significance | |||
Determination Process, could not be used due to the licensees inability to | |||
quantify the increase in risk associated with the heavy equipment activity in the | |||
- 2 - | |||
Enclosure 2 | |||
switchyard. The inspectors therefore used Manual Chapter 0609, Appendix M, | |||
Significance Determination Process Using Qualitative Criteria. The inspectors | |||
performed a bounding qualitative evaluation using the best available information | |||
and determined that the finding was of very low safety significance because | |||
another qualified source of offsite power (the emergency transformer) was | |||
unaffected by this performance deficiency and provided sufficient remaining | |||
defense in depth in the event of a loss of offsite power. This finding has a | |||
crosscutting aspect in the area of problem identification and resolution | |||
Cornerstone: Mitigating Systems | associated with the corrective action program component because the licensee | ||
* | did not take appropriate corrective actions to address safety issues and adverse | ||
trends in a timely manner, commensurate with their safety significance and | |||
complexity [P.1(d)](Section 1R13). | |||
Cornerstone: Mitigating Systems | |||
* | |||
Green. The inspectors identified a noncited violation of | |||
10 CFR Part 55.59 (a)(2)(ii), Requalification, for the failure of the licensee to | |||
ensure that three senior operator license holders were evaluated during the | |||
annual operating test to the appropriate level of their license. This issue was | |||
entered into the licensees corrective action program as Condition | |||
Report CR-CNS-2010-09350. | |||
The failure of the licensee to properly evaluate the three senior operators to the | |||
level of their license in the annual operating test was a performance deficiency. | |||
The performance deficiency is more than minor, and therefore a finding, because | |||
it adversely impacted the human performance attribute of the Mitigating Systems | |||
Cornerstone objective of ensuring the availability, reliability, and capability of | |||
systems that respond to initiating events to prevent undesirable consequences. | |||
Additionally, if left uncorrected, the performance deficiency could have become | |||
more significant in that allowing licensed operators to return to the control room | |||
without valid demonstration of appropriate knowledge on the biennial | |||
examinations could be a precursor to a significant event if undetected | |||
performance deficiencies develop. Using Manual Chapter 0609, Significance | |||
Determination Process, Phase 1 worksheets, and Appendix M, Significance | |||
Determination Process Using Qualitative Criteria, the finding was determined to | |||
have very low safety significance (Green) because, although the finding resulted | |||
* | in three senior operator license holders standing watch in the senior operator | ||
position without being properly evaluated during the annual operating test, there | |||
were no actual safety consequences. This finding has a crosscutting aspect in | |||
the area of human performance associated with the decision making component | |||
because the licensee failed to use conservative assumptions in decision making | |||
and adopt a requirement to demonstrate that the proposed action is safe in order | |||
to proceed rather than a requirement to demonstrate that it is unsafe in order to | |||
disapprove the action [H.1(b)] (Section 1R11). | |||
* | |||
Green. The inspectors identified a noncited violation of 10 CFR 50 Appendix B, | |||
Criterion V, Instructions, Procedures and Drawings, regarding the licensees | |||
- 3 - | |||
Enclosure 2 | |||
failure to follow the requirements of Administrative Procedure 0.5.CR, Condition | |||
Report Initiation, Review and Classification. to enter conditions adverse to | |||
quality into the corrective action program. Specifically, between January 12, | |||
2011, and February 24, 2011, the inspectors identified multiple instances where | |||
licensee personnel were aware of conditions adverse to quality, but failed to | |||
appropriately enter them into the corrective action program until being prompted | |||
by the inspectors. The licensee entered this issue in their corrective action | |||
program as CR-CNS-2011-1239. | |||
The performance deficiency associated with this finding involved the licensees | |||
failure to initiate condition reports as required by Administrative Procedure | |||
0.5.CR, Condition Report Initiation, Review and Classification. The | |||
performance deficiency was more than minor because it affected the equipment | |||
performance attribute of the Mitigating Systems Cornerstone, and directly | |||
affected the cornerstone objective to ensure the availability, reliability, and | |||
capability of systems that respond to initiating events to prevent undesirable | |||
consequences. Although the examples mentioned above may be minor | |||
violations, the inspectors used Section 2.10.F of the NRC Enforcement Manual to | |||
determine that the performance deficiency was more than minor and is therefore | |||
a finding because the NRC has indication that the minor violation had occurred | |||
repeatedly. Using the Manual Chapter 0609, Attachment 4, Phase 1 - Initial | |||
Screening and Characterization of Findings, the inspectors determined that the | |||
finding has very low safety significance because all of the items in the | |||
Table 4a Mitigating Systems Cornerstone checklist were answered in the | |||
negative. The finding has a crosscutting aspect in the area of problem | |||
identification and resolution associated with the corrective action program | |||

November 24, 2010, and March 24, 2011 multiple occasions were identified | |||
where licensee personnel failed to implement appropriate foreign material | |||
exclusion controls in areas designated as Zone 1 areas around safety related | |||
equipment (e.g., failure to appropriately log material into and out of the zone, or | |||
appropriately lanyard material in the zone) as required by station procedure. | |||
This issue was entered into the licensee's corrective action program as Condition | |||
Reports CR-CNS-2010-9173, CR-CNS-2010-9678, CR-CNS-2011-2775 and CR- | |||
CNS-2011-3214. | |||
. The inspectors identified a noncited violation of 10 CFR Part 50, | |||
Appendix B, Criterion V, Instructions, Procedures, and Drawings, associated | |||
with the licensees failure to adequately implement Procedure 0.45, Foreign | |||
Material Exclusion Program, Revision 33. Specifically, between | |||
- 4 - | |||
Enclosure 2 | |||
The failure of station personnel to follow Procedure 0.45, Foreign Material | |||
Exclusion Program, when working in Zone 1 foreign material exclusion areas | |||
around safety related equipment/areas, was a performance deficiency. The | |||
performance deficiency was more than minor because it affected the human | |||
performance attribute of the Barrier Integrity Cornerstone, and directly affected | |||
the cornerstone objective of providing reasonable assurance that physical | |||
barriers protect the public from radionuclide releases caused by accidents or | |||
events, and is therefore a finding. Furthermore, station personnels continued | |||
failure to implement appropriate foreign material exclusion controls could result in | |||
the introduction of foreign material into critical areas, such as the spent fuel pool | |||
or the reactor cavity, which in turn could result in degradation and adverse | |||
impacts on materials and systems associated with these areas. Using Inspection | |||
Manual Chapter 0609, Significance Determination Process, Phase 1 | |||
Worksheets (at power issues), and Manual Chapter 0609, Appendix G, | |||
Shutdown Operations Significance Determination Process, Phase 1 guidance | |||
(shutdown issues), this finding was determined to have a very low safety | |||
significance because; the finding was only associated with the fuel barrier (at | |||
power), and did not result in an increase in the likelihood of a loss of reactor | |||
coolant system inventory, degrade the ability to add reactor coolant system | |||
inventory, or degrade the ability to recover decay heat removal (shutdown). This | |||
Cornerstone: Miscellaneous | finding had a crosscutting aspect in the area of human performance associated | ||
* | with the work practices component, in that the licensee failed to define and | ||
effectively communicate expectations regarding procedural compliance and | |||
personnel follow procedures [H.4(b)] (Section 1R20). | |||
Cornerstone: Miscellaneous | |||
* | |||
Severity Level IV. The inspectors identified a Severity Level IV noncited violation | |||
of 10 CFR 50.72, Immediate Notification Requirements for Operating Nuclear | |||
Power Reactors, for the licensees failure to notify the NRC Operations Center | |||
within 8 hours following discovery of an event meeting the reportability criteria as | |||
specified. Specifically, on January 18, 2011, while the B train of residual heat | |||
removal was inoperable for scheduled maintenance the A train experienced a | |||
fault which rendered it inoperable for its low pressure coolant injection function. | |||
As a result, both trains of residual heat removal were incapable of performing | |||
their system specified safety function of residual heat removal. The licensees | |||
evaluation of this condition determined that it was not a reportable event because | |||
both core spray pumps were operable and the D residual heat removal pump | |||
was available therefore the overall function of decay heat removal was | |||
maintained. The inspectors questioned this rational, because the apparent intent | |||
of the reporting criteria as described in NUREG 1022, Event Reporting | |||
Guidelines 50.72 and 50.73, Revision 2, section 3.2.7, was to cover an event or | |||
condition where structures, components, or trains of a safety system could have | |||
failed to perform their intended safety function as described in the plant safety | |||
analysis. Consultation with the Office of Nuclear Reactor Regulation determined | |||
that this was the intent of the criteria. As such, the inspectors determined that | |||
the licensee had failed to make a non-emergency 8 hour report as required by 10 | |||
- 5 - | |||
Enclosure 2 | |||
CFR 50.72(b)(3)(v). The licensee submitted the 8 hour report on January 21, | |||
2011 and entered this issue into the corrective action program as Condition | |||
Report CR-CNS-2011-0618. | |||
The failure to make an applicable non-emergency 8-hour event notification report | |||
within the required time frame was determined to be a performance deficiency. | |||
The inspectors reviewed this issue in accordance with NRC Inspection Manual | |||
Chapter 0612 and the NRC Enforcement Manual. Through this review, the | |||
inspectors determined that traditional enforcement was applicable to this issue | |||
because the NRC's regulatory ability was affected. Specifically, the NRC relies | |||
on the licensees to identify and report conditions or events meeting the criteria | |||
specified in regulations in order to perform its regulatory function; and when this | |||
is not done, the regulatory function is impacted. The inspectors determined that | |||
this finding was not suitable for evaluation using the significance determination | |||
process, and as such, was evaluated in accordance with the NRC Enforcement | |||
Policy. The finding was reviewed by NRC management and because the | |||
violation was determined to be of very low safety significance, was not repetitive | |||
or willful, and was entered into the corrective action program, this violation is | |||
B. Licensee-Identified Violations | being treated as a Severity Level IV noncited violation consistent with the NRC | ||
Enforcement Policy. This finding had a crosscutting aspect in the area of human | |||

Readiness to Cope with External Flooding | |||
a. | |||
The inspectors evaluated the design, material condition, and procedures for coping with | |||
the design basis probable maximum flood. The evaluation included a review to check | |||
for deviations from the descriptions provided in the Updated Final Safety Analysis Report | |||
for features intended to mitigate the potential for flooding from external factors. As part | |||
of this evaluation, the inspectors checked for obstructions that could prevent draining, | |||
checked that the roofs did not contain obvious loose items that could clog drains in the | |||
event of heavy precipitation, and determined that barriers required to mitigate the flood | |||
were in place and operable. Additionally, the inspectors performed an inspection of the | |||
protected area to identify any modification to the site that would inhibit site drainage | |||
during a probable maximum precipitation event or allow water ingress past a barrier. | |||
The inspectors also reviewed the abnormal operating procedure for mitigating the design | |||
basis flood to ensure it could be implemented as written. Specific documents reviewed | |||
during this inspection are listed in the attachment. | |||
Inspection Scope | |||
The inspectors reviewed Cooper Nuclear Stations external flood protection strategy to | |||
resolve unresolved item URI 05000298/2010005-06, Failure to Update Flood Protection | |||
for Safety Related Buildings. The inspectors verified that flood protection strategy would | |||
adequately protect to the flood levels stated in the Updated Final Safety Analysis Report. | |||
Since the inspectors verified the adequacy of the external flood protection strategy to | |||
design basis flood levels, URI 05000298/2010005-06 is closed. | |||

systems: | |||
Inspection Scope | |||
* | |||
High pressure coolant injection system | |||
* | |||
Fuel pool cooling decontamination flush/alternate decay heat removal | |||
* | |||

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, 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. | |||

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. | |||

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 were | |||
administered an operating test consisting of job performance measures and simulator | |||
scenarios. In the second part of the training cycle, the biennial cycle, operators were | |||
administered an operating test and a comprehensive written examination. | |||
Biennial Review | |||

Enclosure 2 | |||
a. | |||
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. | |||
Inspection Scope | |||
The inspectors interviewed six licensee personnel, consisting of two reactor operators, | |||
two senior operators, one simulator supervisor and one operations training supervisor 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 observed included two job | |||
performance measures and two 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 one operator. | |||
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 minutes of | |||
training review group meetings to assess the responsiveness of the licensed operator | |||
requalification program to incorporate the lessons learned from both plant and industry | |||
events. Examination results were also assessed to determine if they were consistent | |||
with the guidance contained in NUREG 1021, "Operator Licensing Examination | |||
b. | Standards for Power Reactors," Revision 9, Supplement 1, and NRC Manual | ||
Chapter 0609, Appendix I, "Operator Requalification Human Performance Significance | |||
Determination Process." | |||
In addition to the above, the inspectors reviewed examination security measures, | |||
simulator fidelity and existing logs of simulator deficiencies. | |||
The inspectors completed one inspection sample of the biennial licensed operator | |||
requalification program. | |||
b. | |||
Introduction. The inspectors identified a Green noncited violation of | |||
10 CFR Part 55.59 (a)(2)(ii), Requalification, for the failure of the licensee to ensure | |||
that all senior operator license holders were evaluated during the annual operating test. | |||
Three of the twenty-nine senior operator license holders were not evaluated during the | |||
annual operating test due to the licensees interpretation of Frequently Asked Questions | |||
Inspection Procedure .3 on the Operator Licensing section of the NRC website. This | |||
failure resulted in three senior operator license holders standing watch without being | |||
properly evaluated during the annual operating test, but did not lead to any actual safety | |||
consequences. | |||
Findings | |||
Description. On November 30, 2010, while performing a biennial requalification | |||
inspection in accordance with Inspection Procedure 71111.11, Licensed Operator | |||

- 12 - | |||
Enclosure 2 | |||
activity that compromised the ability to evaluate three senior operators according to | |||
10 CFR 55.59 (a)(2)(ii). Specifically, three senior operators were not evaluated in the | |||
senior operator position during scenarios and instead were evaluated in the reactor | |||
operator position for which they normally stand. This resulted in three senior operators | |||
standing watch in the senior operator position without properly being evaluated in the | |||
annual operating test. The inspectors determined that there were no actual safety | |||
consequences due to the three senior operators standing watch without being properly | |||
evaluated. Because this finding is of very low safety significance and has been entered | |||

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 | |||

Introduction. The inspectors identified a Green cited violation of 10 CFR 50.65(a)(4), | |||
Requirements for Monitoring the Effectiveness of Maintenance at Nuclear Power | |||
Plants, for the failure of work control and operations personnel to adequately assess | |||
and manage the increase in risk associated with maintenance activities. Specifically, on | |||
February 17, 2011, work control and operations personnel failed to adequately assess | |||
and manage the increase in risk associated with maintenance activities involving the use | |||
heavy equipment in or near the electrical switchyard and offsite power components. | |||
Findings | |||
Description. During plant status activities on February 17, 2011, inspectors noticed | |||
heavy equipment work in the switchyard. The work involved a 100 ton crane, a small | |||
crane, service trucks, oil tankers, semi tractors and a vacuum trailer. The inspectors | |||
questioned whether these maintenance activities, that could increase the likelihood of | |||
initiating events, were considered in the stations on-line risk assessment. The | |||
inspectors determined that the risk assessment was inadequate in that it had not | |||
assessed all initiating events and the activity was not included in the overall on-line plant | |||
risk. | |||
The inspectors were aware that the plant was in a planned elevated (Yellow) risk window | |||
due to ongoing maintenance of the high pressure coolant injection pump. The | |||
inspectors were also aware that past switchyard work had been performed with | |||
inadequate risk assessments indicating a deficiency in the licensees ability to blend | |||
qualitative and quantitative risk assessments. The inspectors contacted the control | |||
room staff to obtain a copy of the risk assessment for this work and discuss the work | |||
being performed during the Yellow risk window. The inspectors reviewed work | |||
order 4786633 and noted that the risk assessment only evaluated a loss of offsite power | |||
and no other initiating events were considered. The switchyard risk assessment | |||
concluded the work was medium risk and did not evaluate that risk against the Yellow | |||
probabilistic risk assessment risk window in progress for the high pressure coolant | |||
injection pump work during the switchyard work. The control room stopped work in the | |||
switchyard yard until the condition could be resolved and initiated CR-CNS-2011-01439. | |||
The inspectors reviewed the requirements of Administrative Procedure 0.49, Schedule | |||
Risk Assessment, Revision 24 and noted no requirement to review the list of initiating | |||
events for any significant potential of work to increase risk to the many possible initiating | |||
events other than a loss of offsite power. | |||
The inspectors had noted several previous failures to perform a qualitative risk | |||
assessments in accordance with 10 CFR 50.65(a)(4) for work in the switchyard and | |||
transformer yard. Three weeks earlier the inspectors noted heavy equipment work in the | - 15 - | ||

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 Updated | |||
Final Safety Analysis Report 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 | |||

Introduction. The inspectors identified a Green noncited violation of 10 CFR Part 50, | |||
Appendix B, Criterion V, Instructions, Procedures, and Drawings, associated with the | |||
licensees failure to adequately implement Procedure 0.45, Foreign Material Exclusion | |||
Program, Revision 33. | |||
Findings | |||
Description. On November 24, 2010, while performing reviews of the licensees | |||
activities associated with the dry cask storage campaign, the inspectors noted that | |||
condition reports CR-CNS-2010-6645, CR-CNS-2010-7355, and CR-CNS-2010-8940 | |||
detailed instances where foreign material had been found in a Zone 1 foreign material | |||
exclusion area (areas which required the highest level of foreign material exclusion | |||
controls), specifically the spent fuel pool. When the inspectors reviewed the applicable | |||
sections of Station procedure 0.45 specific actions and documentation requirements | |||
were noted for a loss of area integrity. Specifically, Attachment 10, Loss of Integrity | |||
Actions and Notification Recovery Plan, was to be completed and attached to the | |||
condition report. The inspectors noted that for the instances being reviewed these | |||
attachments were not with the condition reports. The inspectors pointed this out to the | |||
licensee who subsequently determined that the procedural requirements had not been | |||
followed. This issue was entered into the licensees corrective action program as | |||
condition report CR-CNS-2010-9173. | |||
On December 30, 2010, while conducting a routine tour of the spent fuel floor the | |||
inspectors noted work in the area of a dry fuel canister, which had been designated as a | |||
zone 1 foreign material exclusion area, was not in accordance with station procedures. | |||
Specifically, individuals working in the area were not appropriately implementing the | |||
requirements of Procedure 0.45 because they were wearing jewelry in the area, and had | |||
material in their pockets. The inspectors informed the licensee of this issue and it was | |||
entered into the stations corrective action program as condition report CR-CNS-2010- | |||
9678. | |||
Based on these observations, and a concern with the implementation of the stations | |||
foreign material exclusion program, the inspectors performed increased monitoring of | |||
this program, including observations during the beginning of refueling outage RE-26. | |||
Through increased observations in and around other Zone 1 foreign material exclusion | |||
areas the inspectors noted eleven additional instances where licensee personnel failed | |||
to appropriately implement procedural requirements associated with Zone 1 foreign | |||
material exclusion controls. One of these instances, as stated below, actually resulted in | |||
the loss of control of items that were inadvertently introduced into the reactor vessel. | |||

Training Observations | |||
a. | |||
The inspectors observed a simulator training evolution for licensed operators on | |||
February 9, 2011, which required emergency plan implementation by a licensee | |||
operations crew. This evolution was planned to be evaluated and included in | |||
performance indicator data regarding drill and exercise performance. The inspectors | |||
observed event classification and notification activities performed by the crew. The | |||
inspectors also attended the postevolution critique for the scenario. The focus of the | |||
inspectors activities was to note any weaknesses and deficiencies in the crews | |||
performance and ensure that the licensee evaluators noted the same issues and entered | |||
them into the corrective action program. As part of the inspection, the inspectors | |||
reviewed the scenario package and other documents listed in the attachment. | |||

a. | |||
Inspection Scope | |||
On January 18, 2011, the inspectors responded to the control room when the licensee | |||
determined that both trains of residual heat removal were inoperable with respect to the | |||
low pressure coolant injection function, which resulted in the unplanned entry into | |||
Technical Specification Limiting Condition for Operation 3.0.3. Subsequently, the | |||
licensee was able to restore the B train of residual heat removal to an operable | |||
condition and exit Technical Specification Limiting Condition for Operation 3.0.3. | |||
Inspectors toured the control room during the event to verify stable plant conditions, | |||
monitored the licensees actions to restore the B train of residual heat removal, | |||
reviewed station logs, discussed the event with the operations and maintenance staff | |||
and reviewed NUREG-1022, Event Reporting Guidelines, Revision 2, to ensure | |||
licensee compliance. | |||

Introduction. The inspectors identified a Severity Level IV noncited violation | |||
of 10 CFR 50.72, Immediate Notification Requirements for Operating Nuclear Power | |||
Reactors, for the licensees failure to notify the NRC Operations Center within 8 hours | |||
following discovery of an event meeting the reportability criteria as specified. | |||
Findings | |||
Description. On January 18, 2011, at 2:30 p.m. the licensee made the B train of residual | |||
heat removal inoperable for scheduled maintenance. Subsequently, at 4:30 p.m. while | |||
performing a panel walk down, an operator noted that the open position indicating light | |||
for the A reactor recirculation pump discharge valve, RR-MOV-53A, was blown. Further | |||
investigation by maintenance team determined that the control power circuit for the valve | |||
was deenergized. | |||
Valve RR-MOV-53A must close at a specified reactor pressure to allow the A train of | |||
residual heat removal to inject to the core during a loss of coolant accident involving | |||
reactor recirculation loop A. The deenergized control power circuit rendered the A train | - 31 - | ||

(Closed) LER 050002982010003, Low Voltage on Emergency Transformer Causes | |||
Loss of Safety Function | |||
On August 24, 2010, a low voltage condition occurred on the offsite power supply to the | |||
emergency station service transformer during planned maintenance on the station | |||
startup service transformer. Subsequently, emergency station service transformer | |||
secondary voltage dropped below the level where essential 4160 volt alternating current | |||
buses will automatically load onto the emergency station service transformer. Control | |||
room operators declared the emergency station service transformer inoperable and | |||
entered the Technical Specification limiting condition for operation condition for two | |||
offsite circuits inoperable. After two minutes, emergency station service transformer | |||
secondary voltage was restored to the proper level and the control room operators | |||
returned the emergency station service transformer to operable status. The cause of | |||
this event was the licensees review of a revised switching order, associated with | |||

Brownville, NE 68321
Subject: COOPER NUCLEAR STATION - NRC INTEGRATED INSPECTION REPORT
NUMBER 05000298/2011002 AND NOTICE OF VIOLATION
Dear Mr. OGrady:
On March 24, 2011, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection
at your Cooper Nuclear Station. The enclosed integrated inspection report documents the
inspection findings, which were discussed on March 29, 2011, with you 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 identified an issue that was evaluated
under the risk significance determination process as having very low safety significance
(Green). The NRC has also determined that a violation is associated with this issue.
This violation was evaluated in accordance with the NRC Enforcement Policy. The current
Enforcement Policy is included on the NRC's Web site at
(http://www.nrc.gov/about-nrc/regulatory/enforcement/enforce-pol.html).
The violation is cited in the enclosed Notice of Violation (Notice) and the circumstances
surrounding it are described in detail in the subject inspection report. The violation involved the
failure to appropriately assess and manage the risk associated with planned maintenance
activities. The violation is being cited in the Notice because the licensee failed to restore
compliance with NRC requirements within a reasonable time after violations were identified in
Inspection Reports 05000298/2009005, 2010002, and 2010005. This is consistent with the
NRC Enforcement Policy; Section 2.3.2, which states, in part, that a cited violation will be

considered if the licensee fails to restore compliance within a reasonable time after a violation is
identified.
You are required to respond to this letter and should follow the instructions specified in the
enclosed Notice when preparing your response. If you have additional information that you
believe the NRC should consider, you may provide it in your response to the Notice. The NRC
review of your response to the Notice will also determine whether further enforcement action is
necessary to ensure compliance with regulatory requirements.
Based on the results of this inspection, the NRC has also determined that one additional
Severity Level IV violation of NRC requirements occurred, and three additional issues that were
evaluated under the risk significance determination process as having very low safety
significance (Green). The NRC has determined that violations are associated with these issues.
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 significance and
because they were entered into your corrective action program, the NRC is treating these
findings as a noncited violations, consistent with Section 2.3.2 of the NRC Enforcement Policy.
If you contest the violation or the significance of the 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, 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.
In accordance with 10 CFR 2.390 of the NRC's "Rules of Practice," a copy of this letter, its
enclosures, and your response, if you choose to provide one, will be made available
electronically for public inspection in the NRC Public Document Room or from the NRC's
document system (ADAMS), accessible from the NRC Website at http://www.nrc.gov/reading-

Cooper Nuclear Station
License No. DPR-46
EA-2010-090
During an NRC inspection conducted January 1 through March 24, 2011, a violation of NRC
requirements was identified. In accordance with the NRC Enforcement Policy, the violation is
listed below:
Title 10 CFR 50.65(a)(4), Requirements for Monitoring the Effectiveness of
Maintenance at Nuclear Power Plants, requires, in part, that before performing
maintenance activities the licensee shall assess and manage the increase in risk that
may result from the proposed maintenance activities.
Contrary to the above, from November 26, 2008 through February 17, 2011 work control
and operations personnel failed to adequately access and manage the increase in risk
associated with maintenance activities. Specifically, qualitative assessments of
maintenance activities in or near the electrical switchyard and offsite power components
were not included in the on-line risk assessment.
This violation is associated with a Green Significance Determination Process finding.
Pursuant to the provisions of 10 CFR 2.201, Cooper Nuclear Station is hereby required to
submit a written statement or explanation to the U.S. Nuclear Regulatory Commission, ATTN:
Document Control Desk, Washington, DC 20555-0001 with a copy to the Regional
Administrator, Region IV, and a copy to the NRC Resident Inspector at the facility that is the
subject of this Notice, within 30 days of the date of the letter transmitting this Notice of Violation
(Notice). This reply should be clearly marked as a "Reply to a Notice of Violation; EA-2011-090"
and should include for each violation: (1) the reason for the violation, or, if contested, the basis
for disputing the violation or severity level, (2) the corrective steps that have been taken and the
results achieved, (3) the corrective steps that will be taken, and (4) the date when full
compliance will be achieved. Your response may reference or include previous docketed
correspondence, if the correspondence adequately addresses the required response. If an
adequate reply is not received within the time specified in this Notice, an order or a Demand for
Information may be issued as to why the license should not be modified, suspended, or
revoked, or why such other action as may be proper should not be taken. Where good cause is
shown, consideration will be given to extending the response time.
If you contest this enforcement action, you should also provide a copy of your response, with
the basis for your denial, to the Director, Office of Enforcement, United States Nuclear
Regulatory Commission, Washington, DC 20555-0001.
Because your response will be made available electronically for public inspection in the NRC
Public Document Room or from the NRCs document system (ADAMS), accessible from the
NRC Web site at http://www.nrc.gov/reading-rm/adams.html, to the extent possible, it should not
include any personal privacy, proprietary, or safeguards information so that it can be made

available to the public without redaction. If personal privacy or proprietary information is
necessary to provide an acceptable response, then please provide a bracketed copy of your
response that identifies the information that should be protected and a redacted copy of your
response that deletes such information. If you request withholding of such material, you must
specifically identify the portions of your response that you seek to have withheld and provide in
detail the bases for your claim of withholding (e.g., explain why the disclosure of information will
create an unwarranted invasion of personal privacy or provide the information required by
10 CFR 2.390(b) to support a request for withholding confidential commercial or financial
information). If safeguards information is necessary to provide an acceptable response, please

SUMMARY OF FINDINGS
IR 05000298/2011002; 01/01/2011 - 03/24/2011; Cooper Nuclear Station, Integrated Resident
and Regional Report; Licensed Operator Requalification Program, Maintenance Risk
Assessments and Emergent Work Control, Refueling and Other Outage Activities, Identification
and Resolution of Problems, and Event Follow-up.
The report covered a 3-month period of inspection by resident inspectors and an announced
baseline inspections by region-based inspectors. One Green cited violation, three Green
noncited violations, 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: Initiating Events
Green. The inspectors identified a cited violation of 10 CFR 50.65(a)(4),
Requirements for Monitoring the Effectiveness of Maintenance at Nuclear Power
Plants, for the failure of work control and operations personnel to adequately
assess and manage the increase in risk associated with maintenance activities.
Specifically, on February 17, 2011, work control and operations personnel failed
to adequately assess and manage the increase in risk associated with
maintenance activities involving the use of heavy equipment in or near the
electrical switchyard and offsite power components. Due to the licensees failure
to restore compliance from the previous NCV 050000298/2008005-02 and other
subsequent violations within a reasonable time after the violations were
identified, this violation is being cited in a Notice of Violation consistent with
Section 2.3.2 of the NRC Enforcement Policy. This finding was entered into the
licensees corrective action program as condition reports CR-CNS-2010-09146,
CR-CNS-2008-08645 and CR-CNS-2009-03714.
The performance deficiency associated with this finding involved the licensees
failure to adequately assess and manage the risk of planned maintenance
activities. This finding is greater than minor because it affected the protection
against external factors attribute of the Initiating Events Cornerstone, and directly
affected the cornerstone objective to limit the likelihood of those events that
upset plant stability and challenge critical safety functions during shutdown as
well as power operations. The inspectors determined that Manual Chapter 0609,
Appendix K, Maintenance Risk Assessment and Risk Management Significance
Determination Process, could not be used due to the licensees inability to
quantify the increase in risk associated with the heavy equipment activity in the
- 2 -
Enclosure 2
switchyard. The inspectors therefore used Manual Chapter 0609, Appendix M,
Significance Determination Process Using Qualitative Criteria. The inspectors
performed a bounding qualitative evaluation using the best available information
and determined that the finding was of very low safety significance because
another qualified source of offsite power (the emergency transformer) was
unaffected by this performance deficiency and provided sufficient remaining
defense in depth in the event of a loss of offsite power. This finding has a
crosscutting aspect in the area of problem identification and resolution
associated with the corrective action program component because the licensee
did not take appropriate corrective actions to address safety issues and adverse
trends in a timely manner, commensurate with their safety significance and
complexity P.1(d)(Section 1R13).
Cornerstone: Mitigating Systems
Green. The inspectors identified a noncited violation of
10 CFR Part 55.59 (a)(2)(ii), Requalification, for the failure of the licensee to
ensure that three senior operator license holders were evaluated during the
annual operating test to the appropriate level of their license. This issue was
entered into the licensees corrective action program as Condition
Report CR-CNS-2010-09350.
The failure of the licensee to properly evaluate the three senior operators to the
level of their license in the annual operating test was a performance deficiency.
The performance deficiency is more than minor, and therefore a finding, because
it adversely impacted the human performance attribute of the Mitigating Systems
Cornerstone objective of ensuring the availability, reliability, and capability of
systems that respond to initiating events to prevent undesirable consequences.
Additionally, if left uncorrected, the performance deficiency could have become
more significant in that allowing licensed operators to return to the control room
without valid demonstration of appropriate knowledge on the biennial
examinations could be a precursor to a significant event if undetected
performance deficiencies develop. Using Manual Chapter 0609, Significance
Determination Process, Phase 1 worksheets, and Appendix M, Significance
Determination Process Using Qualitative Criteria, the finding was determined to
have very low safety significance (Green) because, although the finding resulted
in three senior operator license holders standing watch in the senior operator
position without being properly evaluated during the annual operating test, there
were no actual safety consequences. This finding has a crosscutting aspect in
the area of human performance associated with the decision making component
because the licensee failed to use conservative assumptions in decision making
and adopt a requirement to demonstrate that the proposed action is safe in order
to proceed rather than a requirement to demonstrate that it is unsafe in order to
disapprove the action H.1(b) (Section 1R11).
Green. The inspectors identified a noncited violation of 10 CFR 50 Appendix B,
Criterion V, Instructions, Procedures and Drawings, regarding the licensees

failure to follow the requirements of Administrative Procedure 0.5.CR, Condition
Report Initiation, Review and Classification. to enter conditions adverse to
quality into the corrective action program. Specifically, between January 12,
2011, and February 24, 2011, the inspectors identified multiple instances where
licensee personnel were aware of conditions adverse to quality, but failed to
appropriately enter them into the corrective action program until being prompted
by the inspectors. The licensee entered this issue in their corrective action
program as CR-CNS-2011-1239.
The performance deficiency associated with this finding involved the licensees
failure to initiate condition reports as required by Administrative Procedure
0.5.CR, Condition Report Initiation, Review and Classification. The
performance deficiency was more than minor because it affected the equipment
performance attribute of the Mitigating Systems Cornerstone, and directly
affected the cornerstone objective to ensure the availability, reliability, and
capability of systems that respond to initiating events to prevent undesirable
consequences. Although the examples mentioned above may be minor
violations, the inspectors used Section 2.10.F of the NRC Enforcement Manual to
determine that the performance deficiency was more than minor and is therefore
a finding because the NRC has indication that the minor violation had occurred
repeatedly. Using the Manual Chapter 0609, Attachment 4, Phase 1 - Initial
Screening and Characterization of Findings, the inspectors determined that the
finding has very low safety significance because all of the items in the
Table 4a Mitigating Systems Cornerstone checklist were answered in the
negative. The finding has a crosscutting aspect in the area of problem
identification and resolution associated with the corrective action program
component, in that the licensee takes appropriate corrective actions to address
safety issues and adverse trends in a timely manner. Specifically, the licensee
failed to take appropriate corrective actions to address previously identified
examples of employees not initiating condition reports in response to conditions
adverse to quality P.1(d) (Section 4AO2).
Cornerstone: Barrier Integrity
Green
November 24, 2010, and March 24, 2011 multiple occasions were identified
where licensee personnel failed to implement appropriate foreign material
exclusion controls in areas designated as Zone 1 areas around safety related
equipment (e.g., failure to appropriately log material into and out of the zone, or
appropriately lanyard material in the zone) as required by station procedure.
This issue was entered into the licensee's corrective action program as Condition
Reports CR-CNS-2010-9173, CR-CNS-2010-9678, CR-CNS-2011-2775 and CR-
. The inspectors identified a noncited violation of 10 CFR Part 50,
Appendix B, Criterion V, Instructions, Procedures, and Drawings, associated
with the licensees failure to adequately implement Procedure 0.45, Foreign
Material Exclusion Program, Revision 33. Specifically, between
- 4 -
Enclosure 2
The failure of station personnel to follow Procedure 0.45, Foreign Material
Exclusion Program, when working in Zone 1 foreign material exclusion areas
around safety related equipment/areas, was a performance deficiency. The
performance deficiency was more than minor because it affected the human
performance attribute of the Barrier Integrity Cornerstone, and directly affected
the cornerstone objective of providing reasonable assurance that physical
barriers protect the public from radionuclide releases caused by accidents or
events, and is therefore a finding. Furthermore, station personnels continued
failure to implement appropriate foreign material exclusion controls could result in
the introduction of foreign material into critical areas, such as the spent fuel pool
or the reactor cavity, which in turn could result in degradation and adverse
impacts on materials and systems associated with these areas. Using Inspection
Manual Chapter 0609, Significance Determination Process, Phase 1
Worksheets (at power issues), and Manual Chapter 0609, Appendix G,
Shutdown Operations Significance Determination Process, Phase 1 guidance
(shutdown issues), this finding was determined to have a very low safety
significance because; the finding was only associated with the fuel barrier (at
power), and did not result in an increase in the likelihood of a loss of reactor
coolant system inventory, degrade the ability to add reactor coolant system
inventory, or degrade the ability to recover decay heat removal (shutdown). This
finding had a crosscutting aspect in the area of human performance associated
with the work practices component, in that the licensee failed to define and
effectively communicate expectations regarding procedural compliance and
personnel follow procedures H.4(b) (Section 1R20).
Cornerstone: Miscellaneous
Severity Level IV. The inspectors identified a Severity Level IV noncited violation
of 10 CFR 50.72, Immediate Notification Requirements for Operating Nuclear
Power Reactors, for the licensees failure to notify the NRC Operations Center
within 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> following discovery of an event meeting the reportability criteria as
specified. Specifically, on January 18, 2011, while the B train of residual heat
removal was inoperable for scheduled maintenance the A train experienced a
fault which rendered it inoperable for its low pressure coolant injection function.
As a result, both trains of residual heat removal were incapable of performing
their system specified safety function of residual heat removal. The licensees
evaluation of this condition determined that it was not a reportable event because
both core spray pumps were operable and the D residual heat removal pump
was available therefore the overall function of decay heat removal was
maintained. The inspectors questioned this rational, because the apparent intent
of the reporting criteria as described in NUREG 1022, Event Reporting
Guidelines 50.72 and 50.73, Revision 2, section 3.2.7, was to cover an event or
condition where structures, components, or trains of a safety system could have
failed to perform their intended safety function as described in the plant safety
analysis. Consultation with the Office of Nuclear Reactor Regulation determined
that this was the intent of the criteria. As such, the inspectors determined that
the licensee had failed to make a non-emergency 8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> report as required by 10

CFR 50.72(b)(3)(v). The licensee submitted the 8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> report on January 21,
2011 and entered this issue into the corrective action program as Condition
Report CR-CNS-2011-0618.
The failure to make an applicable non-emergency 8-hour event notification report
within the required time frame was determined to be a performance deficiency.
The inspectors reviewed this issue in accordance with NRC Inspection Manual
Chapter 0612 and the NRC Enforcement Manual. Through this review, the
inspectors determined that traditional enforcement was applicable to this issue
because the NRC's regulatory ability was affected. Specifically, the NRC relies
on the licensees to identify and report conditions or events meeting the criteria
specified in regulations in order to perform its regulatory function; and when this
is not done, the regulatory function is impacted. The inspectors determined that
this finding was not suitable for evaluation using the significance determination
process, and as such, was evaluated in accordance with the NRC Enforcement
Policy. The finding was reviewed by NRC management and because the
violation was determined to be of very low safety significance, was not repetitive
or willful, and was entered into the corrective action program, this violation is
being treated as a Severity Level IV noncited violation consistent with the NRC
Enforcement Policy. This finding had a crosscutting aspect in the area of human
performance associated with the decision making component, in that, the
licensee failed to use conservative assumptions in their decision making H.1(b)
(Section 4OA3).

Cornerstones: Initiating Events, Mitigating Systems, Barrier Integrity, and
1R01 Adverse Weather Protection (71111.01)
Readiness to Cope with External Flooding
a.
The inspectors evaluated the design, material condition, and procedures for coping with
the design basis probable maximum flood. The evaluation included a review to check
for deviations from the descriptions provided in the Updated Final Safety Analysis Report
for features intended to mitigate the potential for flooding from external factors. As part
of this evaluation, the inspectors checked for obstructions that could prevent draining,
checked that the roofs did not contain obvious loose items that could clog drains in the
event of heavy precipitation, and determined that barriers required to mitigate the flood
were in place and operable. Additionally, the inspectors performed an inspection of the
protected area to identify any modification to the site that would inhibit site drainage
during a probable maximum precipitation event or allow water ingress past a barrier.
The inspectors also reviewed the abnormal operating procedure for mitigating the design
basis flood to ensure it could be implemented as written. Specific documents reviewed
during this inspection are listed in the attachment.
Inspection Scope
The inspectors reviewed Cooper Nuclear Stations external flood protection strategy to
resolve unresolved item URI 05000298/2010005-06, Failure to Update Flood Protection
for Safety Related Buildings. The inspectors verified that flood protection strategy would
adequately protect to the flood levels stated in the Updated Final Safety Analysis Report.
Since the inspectors verified the adequacy of the external flood protection strategy to
design basis flood levels, URI 05000298/2010005-06 is closed.

Partial Walkdown
a.
The inspectors performed partial system walkdowns of the following risk-significant
systems:
Inspection Scope
High pressure coolant injection system
Fuel pool cooling decontamination flush/alternate decay heat removal
Supplemental diesel generator
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, 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 three partial system walkdown samples as

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:
Inspection Scope
January 12, 2011, Residual heat removal 1A heat exchanger room during
residual heat removal valve RHR-101 freeze seal, Zone 2A
January 25, 2011, Torus Area, Zone 1F

elevation, Zone 4C
February 24, 2011, Alternate decay heat removal hot work permit area, reactor
building 958 feet elevation, Zone 4C
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 four quarterly fire-protection inspection samples

Quarterly Review
On February 9, 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:
Inspection Scope
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.

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 were
administered an operating test consisting of job performance measures and simulator
scenarios. In the second part of the training cycle, the biennial cycle, operators were
administered an operating test and a comprehensive written examination.

Enclosure 2
a.
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.
Inspection Scope
The inspectors interviewed six licensee personnel, consisting of two reactor operators,
two senior operators, one simulator supervisor and one operations training supervisor 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 observed included two job
performance measures and two 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 one operator.
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 minutes of
training review group meetings to assess the responsiveness of the licensed operator
requalification program to incorporate the lessons learned from both plant and industry
events. Examination results were also 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."
In addition to the above, the inspectors reviewed examination security measures,
simulator fidelity and existing logs of simulator deficiencies.
The inspectors completed one inspection sample of the biennial licensed operator
requalification program.

Introduction. The inspectors identified a Green noncited violation of
10 CFR Part 55.59 (a)(2)(ii), Requalification, for the failure of the licensee to ensure
that all senior operator license holders were evaluated during the annual operating test.
Three of the twenty-nine senior operator license holders were not evaluated during the
annual operating test due to the licensees interpretation of Frequently Asked Questions
Inspection Procedure .3 on the Operator Licensing section of the NRC website. This
failure resulted in three senior operator license holders standing watch without being
properly evaluated during the annual operating test, but did not lead to any actual safety
consequences.

Enclosure 2
Description. On November 30, 2010, while performing a biennial requalification
inspection in accordance with Inspection Procedure 71111.11, Licensed Operator
Requalification Program, the inspectors discovered that during calendar year 2009,
three senior operators were not properly evaluated during the annual operator test. This
resulted in this group of senior operators standing watch without properly completing the
annual operating test. The licensee had determined at the beginning of 2009, per their
interpretation of Frequently Asked Questions Inspection Procedure .3 on the Operator
Licensing feedback section of the NRC website, that senior operators could be properly
evaluated while in the reactor operator position without rotating to the level of their
license during scenario evaluations. The inspectors informed the licensee that
Frequently Asked Questions Inspection Procedure .3 was intended to allow licensees to
evaluate senior operator license holders in the shift manager position without rotating
them in another scenario back to the control room supervisor position. This would still
allow evaluation of the senior operator in command and control functions and
emergency procedure usage. The three senior operators were evaluated at the
appropriate senior operator position during the 2010 annual operating examination. All
three individuals successfully passed their annual operating examination.
Analysis. The failure of the licensee to properly evaluate the three senior operators to
the level of their license in the annual operating test was a performance deficiency. The
performance deficiency is more than minor, and therefore a finding, because it adversely
impacted the human performance attribute of the Mitigating Systems Cornerstone
objective of ensuring the availability, reliability, and capability of systems that respond to
initiating events to prevent undesirable consequences. Additionally, if left uncorrected,
the performance deficiency could have become more significant in that allowing licensed
operators to return to the control room without valid demonstration of appropriate
knowledge on the biennial examinations could be a precursor to a significant event if
undetected performance deficiencies develop. Using Manual Chapter 0609,
Significance Determination Process, Phase 1 worksheets, and Appendix M,
Significance Determination Process Using Qualitative Criteria, the finding was
determined to have very low safety significance (Green) because, although the finding
resulted in three senior operator license holders standing watch in the senior operator
position without being properly evaluated during the annual operating test, there were no
actual safety consequences. This finding has a crosscutting aspect in the area of
human performance associated with the decision making component because the
licensee failed to use conservative assumptions in decision making and adopt a
requirement to demonstrate that the proposed action is safe in order to proceed rather
than a requirement to demonstrate that it is unsafe in order to disapprove the
action H.1(b).
Enforcement. 10 CFR 55.59, Requalification, requires, in part, that facility licensees
shall pass a comprehensive requalification written exam and operating test to include a
sample of items from 55.45. Among this sample is the ability to demonstrate the
knowledge of the emergency plan for the facility and the ability by the senior operator to
decide whether the plan should be executed and the duties under the plan assigned.
Contrary to the above, during the calendar year of 2009 the licensee engaged in an
- 12 -
Enclosure 2
activity that compromised the ability to evaluate three senior operators according to
10 CFR 55.59 (a)(2)(ii). Specifically, three senior operators were not evaluated in the
senior operator position during scenarios and instead were evaluated in the reactor
operator position for which they normally stand. This resulted in three senior operators
standing watch in the senior operator position without properly being evaluated in the
annual operating test. The inspectors determined that there were no actual safety
consequences due to the three senior operators standing watch without being properly
evaluated. Because this finding is of very low safety significance and has been entered
into the licensees corrective action program as CR-CNS-2010-09350, this violation is
being treated as a noncited violation consistent with Section 2.3.2 of the NRC
Enforcement Policy: NCV 05000298/2011002-01, Failure to Properly Evaluate License
Holders during Annual Operating Test

The inspectors reviewed events such as where ineffective equipment maintenance has
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)

generator 345kV output line and other first quarter work in the switchyard
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
- 14 -
Enclosure 2
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 inspection
samples as defined in Inspection Procedure 71111.13-05.
b.
Introduction. The inspectors identified a Green cited violation of 10 CFR 50.65(a)(4),
Requirements for Monitoring the Effectiveness of Maintenance at Nuclear Power
Plants, for the failure of work control and operations personnel to adequately assess
and manage the increase in risk associated with maintenance activities. Specifically, on
February 17, 2011, work control and operations personnel failed to adequately assess
and manage the increase in risk associated with maintenance activities involving the use
heavy equipment in or near the electrical switchyard and offsite power components.
Findings
Description. During plant status activities on February 17, 2011, inspectors noticed
heavy equipment work in the switchyard. The work involved a 100 ton crane, a small
crane, service trucks, oil tankers, semi tractors and a vacuum trailer. The inspectors
questioned whether these maintenance activities, that could increase the likelihood of
initiating events, were considered in the stations on-line risk assessment. The
inspectors determined that the risk assessment was inadequate in that it had not
assessed all initiating events and the activity was not included in the overall on-line plant
risk.
The inspectors were aware that the plant was in a planned elevated (Yellow) risk window
due to ongoing maintenance of the high pressure coolant injection pump. The
inspectors were also aware that past switchyard work had been performed with
inadequate risk assessments indicating a deficiency in the licensees ability to blend
qualitative and quantitative risk assessments. The inspectors contacted the control
room staff to obtain a copy of the risk assessment for this work and discuss the work
being performed during the Yellow risk window. The inspectors reviewed work
order 4786633 and noted that the risk assessment only evaluated a loss of offsite power
and no other initiating events were considered. The switchyard risk assessment
concluded the work was medium risk and did not evaluate that risk against the Yellow
probabilistic risk assessment risk window in progress for the high pressure coolant
injection pump work during the switchyard work. The control room stopped work in the
switchyard yard until the condition could be resolved and initiated CR-CNS-2011-01439.
The inspectors reviewed the requirements of Administrative Procedure 0.49, Schedule
Risk Assessment, Revision 24 and noted no requirement to review the list of initiating
events for any significant potential of work to increase risk to the many possible initiating
events other than a loss of offsite power.
- 15 -
Enclosure 2
The inspectors had noted several previous failures to perform a qualitative risk
assessments in accordance with 10 CFR 50.65(a)(4) for work in the switchyard and
transformer yard. Three weeks earlier the inspectors noted heavy equipment work in the
switchyard. A review of work orders 4740890, 4806573 and 4809054 found that the
licensee had not identified any risk associated with this work. The station was in a
normal Green risk window and when inspectors walked down the activities they found no
risk mitigation actions were being taken for the work. The control room initiated
CR-CNS-2011-00749 for this improper risk characterization of non-routine switchyard
activities.
On December 7, 2010, while the plant was in a Yellow risk configuration due to
maintenance activities on emergency diesel generator number two, the inspectors
observed transmission personnel using a crane in the electrical switchyard. The
inspectors determined that the work was being performed without an assessment that
considered the increase in risk due to potential initiating events, and the licensee had not
assessed the work to be performed coincident with the emergency diesel generator
Yellow probabilistic assessment risk window. This violation of 10 CFR 50.65(a)(4) was
documented in Inspection Report 05000298/2010005 as noncited violation,
NCV 05000298/2010005-02, Failure to Assess and Manage Risk for Electrical
Switchyard Impacting Maintenance. In response, the licensee issued Revision 0 of the
resulting apparent cause evaluation, CR-CNS-2010-09146, on January 5, 2011. This
revision stated, that an increase in risk did not actually occur and the work activities
would not have challenged CNS with a loss of offsite power initiating event. As a result,
no actions to restore compliance were implemented. Following inspectors Revision 0
comments, Revision 1 of the CR-CNS-2010-09146 apparent cause evaluation was
issued January 10, 2011, that has corrective actions to revise the station risk
management procedures to perform qualitative risk assessments of non-routine
switchyard work that considers the increase in risk to all reasonable initiating events.
The evaluation also identified that two similar noncited violations in 2008 and 2009 for
failure to adequately assess risk for work near the transformer yard only addressed
implementation of additional mitigation actions They did not address the lack of
qualitative risk assessments. The 2008 violation is documented as
NCV 05000298/2008005-02, "Failure to Assess and Manage the Risk of Heavy
Equipment Operations. On November 26, 2008, inspectors noticed heavy equipment
operating within a few feet of the 161 kV transmission line tower to the startup
transformer. The licensee was operating an excavator, a backhoe, a bulldozer and a
dump truck in the area. As part of this activity, the bulldozer had created a large pile of
concrete blocks, the base of which was only a few feet from the transmission tower. The
inspectors were aware that the plant was already in a planned Yellow risk window due to
ongoing maintenance activities that made diesel generator two unavailable. The
inspectors challenged the heavy equipment operators, who were unaware of the
importance of the transmission tower and had not received any specific instructions
regarding standoff distances or other specific precautions. The inspectors contacted the
control room staff, who were unaware of the ongoing heavy equipment operations in the
vicinity of the transmission tower. The control room subsequently stopped work on the
heavy haul road until diesel generator two had been returned to service.
- 16 -
Enclosure 2
This violation was repeated in 2009 and documented as NCV 05000298/2009002-01,
"Repeat Failure to Assess and Manage the Risk of Heavy Equipment Operations. On
January 29, 2009, the licensee was in a Yellow risk configuration due to ongoing repairs
to diesel generator one. Inspectors questioned control room staff to determine if any
heavy equipment operations were anticipated in the vicinity of the transmission line
towers in the protected area during the elevated risk condition. The control room staff
expressed that no such operations were anticipated. Later that shift, the inspectors
noted a water drilling truck operating in the vicinity of the transmission towers. In
maneuvering the drilling truck to unload its contents, the driver pulled the truck to within
one foot of an unprotected leg of the 345 kV transmission tower that provides the first
support for the transmission lines coming from the unit main power transformers. The
inspectors alerted station personnel, who redirected the truck activity to an alternate
route away from the towers. The inspectors promptly informed the control room staff to
allow them to properly assess and manage the risk of the ongoing truck activity in the
vicinity of the transmission towers.
In response to these two issues the licensee implemented corrective actions to identify
equipment in need of protection and posted appropriate signage. No actions were
established to assess the increase in risk associated with maintenance activities.
Analysis. The performance deficiency associated with this finding involved the
licensees failure to assess and manage the risk of planned maintenance activities. This
finding is greater than minor because it affected the protection against external factors
attribute of the Initiating Events Cornerstone, and directly affected the cornerstone
objective to limit the likelihood of those events that upset plant stability and challenge
critical safety functions during shutdown as well as power operations. The inspectors
determined that Manual Chapter 0609, Appendix K, Maintenance Risk Assessment and
Risk Management Significance Determination Process, could not be used due to the
licensees inability to quantify the increase in risk associated with the heavy equipment
activity in the switchyard. The inspectors therefore used Manual Chapter 0609,
Appendix M, Significance Determination Process Using Qualitative Criteria. The
inspectors performed a bounding qualitative evaluation and determined that the finding
was of very low safety significance because another qualified source of offsite power
(the emergency transformer) was unaffected by this performance deficiency and
provided sufficient remaining defense in depth in the event of a loss of offsite power.
This finding has a crosscutting aspect in the area of problem identification and resolution
associated with the corrective action program component because the licensee did not
take appropriate corrective actions 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 50.65(a)(4), states in part, that before performing
maintenance activities, the licensee shall assess and manage the increase in risk that
may result from the proposed maintenance activities. Contrary to the above, from
November 26, 2008 through February 17, 2011 work control and operations personnel
failed to adequately assess and manage the increase in risk associated with
maintenance activities. Specifically, qualitative assessments of maintenance activities in
- 17 -
Enclosure 2
or near the electrical switchyard and offsite power components were not included in the
on-line risk assessment. This finding was of very low safety significance and was
entered into the licensees corrective action program as condition
reports CR-CNS-2011-01439. Because the licensee failed to restore compliance with
NRC requirements within a reasonable time after November 26, 2008, this violation is
being treated as a cited violation, consistent with the NRC Enforcement Policy,
Section 2.3.2, which states, in part, that a cited violation will be considered if the licensee
fails to restore compliance within a reasonable time after a violation is identified:

Could Impact Initiating Events."
1R15 Operability Evaluations (71111.15)
a.
The inspectors reviewed the following issues:
Inspection Scope
January 1, 2011, Control room steam exclusion door
January 13, 2011, Residual heat removal valve RHR-101 failed post work test
January 21, 2011, Diesel generator two lube oil heater leak operability review
February 23, 2011, Residual heat removal service water pipe wall thinning
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 Updated
Final Safety Analysis Report 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.

following (as applicable):
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 Updated
Final Safety Analysis Report, 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.

Introduction. The inspectors identified a Green noncited violation of 10 CFR Part 50,
Appendix B, Criterion V, Instructions, Procedures, and Drawings, associated with the
licensees failure to adequately implement Procedure 0.45, Foreign Material Exclusion
Program, Revision 33.
Findings
Description. On November 24, 2010, while performing reviews of the licensees
activities associated with the dry cask storage campaign, the inspectors noted that
condition reports CR-CNS-2010-6645, CR-CNS-2010-7355, and CR-CNS-2010-8940
detailed instances where foreign material had been found in a Zone 1 foreign material
exclusion area (areas which required the highest level of foreign material exclusion
controls), specifically the spent fuel pool. When the inspectors reviewed the applicable
sections of Station procedure 0.45 specific actions and documentation requirements
were noted for a loss of area integrity. Specifically, Attachment 10, Loss of Integrity
Actions and Notification Recovery Plan, was to be completed and attached to the
condition report. The inspectors noted that for the instances being reviewed these
attachments were not with the condition reports. The inspectors pointed this out to the
licensee who subsequently determined that the procedural requirements had not been
followed. This issue was entered into the licensees corrective action program as
condition report CR-CNS-2010-9173.
On December 30, 2010, while conducting a routine tour of the spent fuel floor the
inspectors noted work in the area of a dry fuel canister, which had been designated as a
zone 1 foreign material exclusion area, was not in accordance with station procedures.
Specifically, individuals working in the area were not appropriately implementing the
requirements of Procedure 0.45 because they were wearing jewelry in the area, and had
material in their pockets. The inspectors informed the licensee of this issue and it was
entered into the stations corrective action program as condition report CR-CNS-2010-
9678.
Based on these observations, and a concern with the implementation of the stations
foreign material exclusion program, the inspectors performed increased monitoring of
this program, including observations during the beginning of refueling outage RE-26.
Through increased observations in and around other Zone 1 foreign material exclusion
areas the inspectors noted eleven additional instances where licensee personnel failed
to appropriately implement procedural requirements associated with Zone 1 foreign
material exclusion controls. One of these instances, as stated below, actually resulted in
the loss of control of items that were inadvertently introduced into the reactor vessel.
- 22 -
Enclosure 2
March 19, 2011, during refueling activities, two ten foot pole sections, that were not
lanyarded as required by procedure, were dropped from the refuel platform onto the
reactor core. These items were immediately retrieved.
The inspectors concluded that not all of these examples of the licensees failure to follow
procedure 0.45, Foreign Material Exclusion Program, directly resulted in the
introduction of foreign material into a critical system. They were, however, indicative of a
programmatic issue associated with the licensees proper implementation of the foreign
material exclusion control program that if left uncorrected could become a more
significant issue.
Analysis. The failure of station personnel to follow Procedure 0.45, Foreign Material
Exclusion Program, when working in Zone 1 foreign material exclusion areas around
safety related equipment/areas, was a performance deficiency. The performance
deficiency was more than minor because it affected the human performance attribute of
the Barrier Integrity Cornerstone, and directly affected the cornerstone objective of
providing reasonable assurance that physical barriers protect the public from
radionuclide releases caused by accidents or events, and is therefore a finding.
Furthermore, station personnels continued failure to implement appropriate foreign
material exclusion controls could result in the introduction of foreign material into critical
areas, such as the spent fuel pool or the reactor cavity, which in turn could result in
degradation and adverse impacts on materials and systems associated with these
areas. Using Inspection Manual Chapter 0609, Significance Determination Process,
Phase 1 Worksheets (at power issues), and Manual Chapter 0609, Appendix G,
Shutdown Operations Significance Determination Process, Phase 1 guidance
(shutdown issues), this finding was determined to have a very low safety significance
because; the finding was only associated with the fuel barrier (at power), and did not
result in an increase in the likelihood of a loss of reactor coolant system inventory,
degrade the ability to add reactor coolant system inventory, or degrade the ability to
recover decay heat removal (shutdown). This finding had a crosscutting aspect in the
area of human performance associated with the work practices component, in that the
licensee failed to define and effectively communicate expectations regarding procedural
compliance and personnel follow procedures H.4(b).
Enforcement. Title 10 of the Code of Federal Regulations 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, of a
type appropriate to the circumstances and shall be accomplished in accordance with
these instructions, procedures, or drawings. Contrary to the above, between November
24, 2010, and March 24, 2011, multiple occasions were identified where licensee
personnel failed to implement appropriate foreign material exclusion controls in areas
designated as Zone 1 foreign material exclusion areas as required by station Procedure
0.45. Because this finding is of very low safety significance and has been entered into
the licensees corrective action program as Condition Reports CR-CNS-2010-9173, CR-
CNS-2010-9678, CR-CNS-2011-2775 and CR-CNS-2011-3214, this violation is being
treated as a noncited violation, consistent with Section 2.3.2 of the NRC Enforcement

Introduction. The inspectors identified a Green noncited violation of 10 CFR 50
Appendix B, Criterion V, Instructions, Procedures and Drawings, regarding the
licensees failure to follow the requirements of Administrative Procedure 0.5, Conduct of
the Condition Reporting Process, and Administrative Procedure 0.5.CR, Condition

Report Initiation, Review and Classification. Specifically, there are multiple examples
where licensee personnel failed to initiate condition reports or failed to initiate condition
reports in a timely manner, per the requirements of 0.5CR, Condition Report Initiation,
Review, And Classification, when problems are identified.
Description. During problem identification and resolution inspections and plant status
inspection activities performed in January and February of 2011 the inspectors
determined that condition reports had not been initiated to document newly-discovered
conditions adverse to quality.
The inspectors noted that Administrative Procedure 0.5, Conduct of the Condition
Report Process, Revision 67, provides overall direction on the conduct of the corrective
action program at Cooper Nuclear Station. Paragraph 7.1.3 provides the following
standard for condition report initiation: Employees and contractors are encouraged to
write condition reports for a broad range of problems. Problems reported must include,
but are not limited to, Adverse Conditions. The procedure goes on to define adverse
conditions as an event, defect, characteristic, state, or activity that prohibits or detracts
from safe, efficient nuclear plant operation or storage of spent nuclear fuel. Adverse
conditions include non-conformances, conditions adverse to quality, and plant reliability
concerns. Administrative Procedure 0.5.CR, Condition Report Initiation, Review and
Classification, provides additional instructions that, If a problem is identified, then a CR
should be initiated no later than the end of the current shift. The inspectors and the
licensees investigation by CR-CNS-2011-01239 have noted condition report initiation
examples affecting several departments including: Design Engineering, Engineering
Support, System Engineering, Columbus General Office (Records & Telecom),
Licensing, Maintenance, Operations, Strategic Initiatives/Projects, Training, Planning
Scheduling & Outages, Quality Assurance, Radiation Protection, and Security.
During baseline inspection activities the inspectors identified multiple adverse conditions
that did not have condition reports initiated until prompted by the inspectors. The
inspectors determined that the following examples met the licensees definition of an
adverse condition, and the condition reports should have been initiated by the end of
shift.
CR-CNS-2011-00544 was initiated January 20, 2011, for condition reports not generated
in accordance with Procedure 0.5CR requirements when issues were identified during
the inspectors January 12, 2011 post maintenance inspection of freeze seal work in the
residual heat removal heat exchanger room. These issues included adequacy of
restraints used on nitrogen dewars secured adjacent to the control rod drive
accumulators, the transient combustible conditions in the residual heat removal heat
exchanger room, overflow of liquid nitrogen on a safety related spring can, and
inspectors indentifying and stopping an escorted visitor from entering the residual heat
removal heat exchanger room without his escort. Followup review of the visitor issue
found that a licensee quality assurance inspector had noted and stopped the behavior of
allowing visitor craft from entering the residual heat removal heat exchanger room
without their escort the previous shift but had not yet issued a condition report on their
finding when the inspectors noted the same behavior. Six additional condition reports
- 28 -
Enclosure 2
were subsequently originated associated with these issues to ensure effective corrective
actions were taken to prevent the risk of additional occurrences.
CR-CNS-2011-0110 was initiated February 7, 2011 following resident inspector
questions on licensee actions in response to an industry cyber security threat
operational experience. The inspector found that the licensee was aware of and had
taken measures to prevent the threat at Cooper Nuclear Station but had not documented
their review or actions in accordance with Procedure 0.5CR requirements.
CR-CNS-2011-01741 was initiated February 24, 2011, on follow up field observations of
the inspectors and licensee personnel for several programmatic and potential fire
protection issues in response to an inspectors February 16, 2011, field observations and
questions on hot work in the reactor building on the alternate decay heat removal
project. The inspectors had previously informed licensee personal that the original
condition report CR-CNS-2011-01413 failed to follow procedure 0.5CR requirements to,
have sufficient detail to provide a clear understanding of the condition.
CR-CNS-2011-01326 was initiated February 14, 2011, following several discussions
between the inspectors and the licensee following the December 27, 2010 inspection of
licensee work on the traversing in-core probe machine. During maintenance of this
equipment the licensee craft and engineering determined that a limit switch circuit board
had an unauthorized modification installed. The licensee initiated the proper
modification to document this condition that had existed since original installation.
However, until this was identified by the inspectors the licensee staff failed to understand
the procedure 0.5CR requirements to document nonconforming conditions to allow an
extent of condition review of the other two affected in-core machines to validate the
installed circuit configuration is adequate. In response, the licensee revised the previous
investigation by CR-CNS-2010-08310 to include this additional extent of condition review
action.
The inspectors reviewed the licensees evaluation of each condition and determined that
none of these conditions resulted in the inoperability of safety-related equipment.
The inspectors noted that similar violations had been documented in inspection reports05000298/2008005-04, Failure to Follow Procedure for Initiating Condition Reports,
and 05000298/2010002-01, Repeat Failure to Follow Procedure for Initiating Condition
Reports. The licensee initiated CR-CNS-2011-01239 on February 10, 2011, to
investigate failures to initiate condition reports in a timely manner. This investigation
reviewed approximately 39 condition reports on this issue from the years 2009, 2010
and 2011. The inspectors reviewed the corrective actions taken for noncited violations
2008005-04 and 2010002-01, and agreed with the licensees CR-CNS-2011-01239
investigation results that determined that there are weaknesses in the reinforcement of
the corrective action program expectations for condition report initiation. Past corrective
actions were taken to reinforce expectations but no actions were taken to make the
expectation reinforcements on a periodic basis. To address this concern the licensee is
implementing a corrective action to, Develop and implement a CAP [corrective action
program] Preventive Maintenance, type of process to provide periodic reinforcement
and monitoring of expectations for CR [condition report] initiation (to include standards
- 29 -
Enclosure 2
for when a CR is needed as well as time limitation), CAP implementation, and CAP
quality. Ensure the process is institutionalized for sustainability.
The inspectors have determined that overall the licensees corrective action program is
effective. However, it does have a programmatic weakness associated with failures to
initiating condition reports. This programmatic weakness indicates that the failure is
more widespread than simple occasional human error. This programmatic weakness is
correctable by the licensees corrective action to institutionalize periodic reinforcement
and monitoring of condition report initiation. This is important to assure that conditions
adverse to quality do not go uncorrected and result in safety related equipment
degradation to occur unnoticed by licensee personnel.
Analysis. The performance deficiency associated with this finding involved the
licensees failure to initiate condition reports as required by Administrative Procedure
0.5.CR, Condition Report Initiation, Review and Classification. The performance
deficiency affected the equipment performance attribute of the Mitigating Systems
Cornerstone, and directly affected the cornerstone objective to ensure the availability,
reliability, and capability of systems that respond to initiating events to prevent
undesirable consequences. Although the examples mentioned above may be minor
violations, the inspectors used Section 2.10.F of the NRC Enforcement Manual to
determine that the performance deficiency was more than minor and is therefore a
finding because the NRC has indication that the minor violation had occurred repeatedly.
Using the Manual Chapter 0609, Attachment 4, Phase 1 - Initial Screening and
Characterization of Findings, the inspectors determined that the finding has very low
safety significance because all of the items in the Table 4a mitigating systems
cornerstone checklist were answered in the negative. The finding has a crosscutting
aspect in the area of problem identification and resolution associated with the corrective
action program component, in that the licensee takes appropriate corrective actions to
address safety issues and adverse trends in a timely manner. Specifically, the licensee
failed to take appropriate corrective actions to address previously identified examples of
employees not initiating condition reports in response to conditions adverse to
quality P.1(d).
Enforcement. 10 CFR 50, Appendix B, Criterion V, Instructions, Procedures and
Drawings requires, in part, that activities affecting quality shall be accomplished in
accordance with procedures of a type appropriate to the circumstances. Administrative
Procedure 0.5CR, Conduct of the Condition Reporting Process, Revision 67, requires
that employees must initiate condition reports for adverse conditions no later than the
end of shift. Contrary to this requirement, from January 12, 2011 to February 24, 2011,
inspectors discovered multiple adverse conditions where the licensee had not initiated
condition reports as required by procedure. Because the finding is of very low safety
significance and has been entered into the licensees corrective action program as
CR-CNS-2011-01239, this violation is being treated as a noncited violation consistent
with Section 2.3.2 of the Enforcement Policy: NCV 05000298/2011002-04, "Repeat

Unplanned entry into Limiting Condition for Operation 3.0.3 due to loss of both trains of
residual heat removal low pressure coolant injection function
a.
Inspection Scope
On January 18, 2011, the inspectors responded to the control room when the licensee
determined that both trains of residual heat removal were inoperable with respect to the
low pressure coolant injection function, which resulted in the unplanned entry into
Technical Specification Limiting Condition for Operation 3.0.3. Subsequently, the
licensee was able to restore the B train of residual heat removal to an operable
condition and exit Technical Specification Limiting Condition for Operation 3.0.3.
Inspectors toured the control room during the event to verify stable plant conditions,
monitored the licensees actions to restore the B train of residual heat removal,
reviewed station logs, discussed the event with the operations and maintenance staff
and reviewed NUREG-1022, Event Reporting Guidelines, Revision 2, to ensure
licensee compliance.
b.
Introduction. The inspectors identified a Severity Level IV noncited violation
of 10 CFR 50.72, Immediate Notification Requirements for Operating Nuclear Power
Reactors, for the licensees failure to notify the NRC Operations Center within 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />
following discovery of an event meeting the reportability criteria as specified.
Findings
Description. On January 18, 2011, at 2:30 p.m. the licensee made the B train of residual
heat removal inoperable for scheduled maintenance. Subsequently, at 4:30 p.m. while
performing a panel walk down, an operator noted that the open position indicating light
for the A reactor recirculation pump discharge valve, RR-MOV-53A, was blown. Further
investigation by maintenance team determined that the control power circuit for the valve
was deenergized.
- 31 -
Enclosure 2
Valve RR-MOV-53A must close at a specified reactor pressure to allow the A train of
residual heat removal to inject to the core during a loss of coolant accident involving
reactor recirculation loop A. The deenergized control power circuit rendered the A train
of residual heat removal inoperable for low pressure coolant injection. As such, at
5:31 p.m. operators declared the A train of residual heat removal inoperable. As a
result, both trains of residual heat removal were inoperable, and incapable of performing
their system specified safety function of residual heat removal. Operators entered
Technical Specification Limiting Condition for Operation 3.0.3, and commenced
preparations for a plant shut down.
Subsequent troubleshooting found a failed light socket that had caused the fuses to
open. The fuses were replaced and the circuit tested satisfactorily. At 7:15 p.m.
residual heat removal Loop "A" low pressure coolant injection was declared operable
and Technical Specification Limiting Condition for Operation 3.0.3 was exited.
The licensee evaluated this event for immediate reportability against the criteria
specified in 10 CFR 50.72, Immediate Notification Requirements for Operating Nuclear
Power Reactors, NUREG 1022, Event Reporting Guidelines 50.72 and 50.73,
Revision 2, and station procedures 2.0.5, Reporting to NRC Operations Center,
Revision 38, and 2.0.11.1, Safety Function Determination Program, Revision 4.
Specifically, the licensee considered 10 CFR 50.72(b)(2)(i), "The initiation of any nuclear
plant shutdown required by the plant's Technical Specifications,"
and 10 CFR 50.72(b)(3)(v), any event or condition that could have prevented the
fulfillment of the safety function of structures or systems that are needed to; A) Shut
down the reactor and maintain it in a safe shutdown condition; B) Remove residual heat;
C) Control the release of radioactive material, or D) Mitigate the consequences of an
accident, as the applicable reportability criteria.
Through their review the licensee determined that the overall decay heat removal safety
function was maintained if three low pressure emergency core cooling system/spray
pumps remained operable/available. The licensee determined that both core spray
pumps A and B were operable and residual heat removal pump D was available (the
pump had an available injection path) at the time of this event. Therefore the licensees
determination was that this event was not reportable under 10 CFR 50.72(b)(3)(v)
because the overall safety function of residual heat removal had been maintained. The
licensee also determined that this event was not reportable under 10 CFR 50.72(b)(2)(i)
since negative reactivity had not been added to the core.
On January 19, 2011, the inspectors reviewed licensees reportability evaluations. The
inspectors questioned the rational used for evaluating reportability
under 10 CFR 50.72(b)(3)(v). Inspectors noted that the apparent intent of this reporting
criteria as described in NUREG 1022, Event Reporting Guidelines 50.72 and 50.73,
Revision 2, Section 3.2.7, was to cover an event or condition where structures,
components, or trains of a safety system could have failed to perform their intended
safety function as described in the plant safety analysis. Consultation with the Office of
Nuclear Reactor Regulation determined that this was the intent of the criteria. While the
- 32 -
Enclosure 2
licensee was correct that the overall decay heat removal function was maintained this
did not meet the intent of the safety system functional failure reportability to report the
failure of the residual heat removal system to perform all designed safety functions. As
such, the inspectors determined that the licensee had failed to make a nonemergency
8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> report as required by 10 CFR 50.72(b)(3)(v).
The inspectors informed the licensee of their concern, and the licensee entered this
issue into their corrective action program as Condition Report CR-CNS-2011-0618.
Subsequently, the licensee made a late notification to the Operations Center on
January 21, 2011.
Analysis. The failure to make an applicable non-emergency 8-hour event notification
report within the required time frame was determined to be a performance deficiency.
The inspectors reviewed this issue in accordance with NRC Inspection Manual Chapter 0612 and the NRC Enforcement Manual. Through this review, the inspectors determined
that traditional enforcement was applicable to this issue because the NRC's regulatory
ability was affected. Specifically, the NRC relies on licensees to identify and report
conditions or events meeting the criteria specified in regulations in order to perform its
regulatory function; and when this is not done, the regulatory function is impacted. The
inspectors determined that this finding was not suitable for evaluation using the
significance determination process, and as such, was evaluated in accordance with the
NRC Enforcement Policy. The finding was reviewed by NRC management and because
the violation was determined to be of very low safety significance, was not repetitive or
willful, and was entered into the corrective action program, this violation is being treated
as a Severity Level IV noncited violation consistent with the NRC Enforcement Policy.
This finding had a crosscutting aspect in the area of human performance associated with
the decision making component, in that, the licensee failed to use conservative
assumptions in their decision making H.1(b).
Enforcement. Title 10 CFR 50.72, Immediate Notification Requirements for Operating
Nuclear Power Reactors, requires, in part, that the licensee shall notify the NRC
Operations Center within 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> after discovery of a non-emergency event described in
paragraph (b)(3)(v). Paragraph (b)(3)(v) of 10 CFR 50.72 requires, in part, that
licensees report any event or condition that could have prevented the fulfillment of the
safety function of structures or systems that are needed to:
Shut down the reactor and maintain it in a safe shutdown condition
Remove residual heat
Control the release of radioactive material
Mitigate the consequences of an accident
Contrary to the above, on January 18, 2011, the licensee failed to notify the NRC
Operations Center within 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> after the discovery of an event or condition that could
have prevented the fulfillment of the safety function. This finding was determined to be
applicable to traditional enforcement because the failure to report conditions or events
meeting the criteria specified in regulations affects the NRCs regulatory ability. The
finding was evaluated in accordance with the NRC's Enforcement Policy. The finding
- 33 -
Enclosure 2
was reviewed by NRC management and because the violation was of very low safety
significance, was not repetitive or willful, and was entered into the corrective action
program, this violation is being treated as a Severity Level IV noncited violation,
consistent with the NRC Enforcement Policy: NCV 05000298/2011002-05, Failure to
Notify the NRC within Eight Hours of a Nonemergency Event.

(Closed) LER 050002982010003, Low Voltage on Emergency Transformer Causes
Loss of Safety Function
On August 24, 2010, a low voltage condition occurred on the offsite power supply to the
emergency station service transformer during planned maintenance on the station
startup service transformer. Subsequently, emergency station service transformer
secondary voltage dropped below the level where essential 4160 volt alternating current
buses will automatically load onto the emergency station service transformer. Control
room operators declared the emergency station service transformer inoperable and
entered the Technical Specification limiting condition for operation condition for two
offsite circuits inoperable. After two minutes, emergency station service transformer
secondary voltage was restored to the proper level and the control room operators
returned the emergency station service transformer to operable status. The cause of
this event was the licensees review of a revised switching order, associated with
planned maintenance on the station startup service transformer, was inadequate.
Specifically, the low voltage condition had occurred due to a change in the component
switching order, and that the station had failed to recognize this change and its potential
to cause the low voltage condition, during their review of the switching order. The
licensee event report was reviewed by the inspectors. Inspectors determined that a
violation had occurred and this issue was documented as NCV 05000298/2010005-03.
This licensee event report is closed.
4OA6 Meetings
Exit Meeting Summary
On December 2, 2010, the inspectors discussed the results of the licensed operator
requalification program inspection with Mr. Art Zaremba, Director of Nuclear Safety, and other
members of the licensee's staff. The lead inspector obtained the final biennial examination
results and telephonically exited with Mr. Art Zaremba, Director of Nuclear Safety, on
January 11, 2011. The licensee representatives acknowledged the finding presented. The
inspectors asked the licensee whether any materials examined during the inspection should be
considered proprietary. No proprietary information was identified.
On March 29, 2011, the resident inspectors presented the inspection results to B. OGrady, and
other members of the licensee staff. The licensee acknowledged the issues presented. The
inspector asked the licensee whether any materials examined during the inspection should be
considered proprietary. No proprietary information was identified.

Enclosure 2
4OA7 Licensee-Identified Violations
The following violation of very low safety significance (Green) was identified by the licensee and
is a violation of NRC requirements which meet the criteria of Section 2.3.2 of the NRC
Enforcement Policy for being dispositioned as noncited violations.
10 CFR 50.65(a)(3) states, in part, that performance and condition monitoring activities
and associated goals and preventive maintenance activities shall be evaluated at least
every refueling cycle provided the interval between evaluations does not exceed
24 months. Contrary to the above, as of August 31, 2010, the licensee had not
completed the (a)(3) assessment in the 24 months since the last assessment period
ended August 2008. When a licensee self assessment determined on February 3, 2011
that they had failed to perform the assessment, Condition Report CR 2011-01003 was
initiated to track completed the assessment and revise the controlling procedure to
prevent recurrence of this condition. The inspectors determined that this issue was of
very low safety significance and no degraded performance or condition of associated
structure, system, and components functions within the scope of the maintenance rule,
resulted from the performance deficiency.
