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, the 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.

=====Description.===== | =====Description.===== | ||
The inspectors selected Condition Report CR-CNS-2013-02324, which had been initiated due to degraded stroke times for HV-AO-272, for review based on the | The inspectors selected Condition Report CR-CNS-2013-02324, which had been initiated due to degraded stroke times for HV-AO-272, for review based on the valves risk significance and previously identified issues with degrading stroke times for the valve. The licensees evaluation determined the likely cause of the degrading stroke times for HV-AO-272 was the use of petroleum based grease, which was not compatible with the ethylene propylene actuator piston seals for HV-AO-272. The petroleum based grease degrades the seal material, causing swelling which resulted in increased actuator friction and longer closing stroke times. The licensee initiated the following corrective actions based on the conclusion of their evaluation documented in Condition Report CR-CNS-2013-02324: | ||
: (1) refurbish HV-AO-272 using the vendor recommended grease compatible with the ethylene propylene actuator piston seals, completed in September 2013; and | : (1) refurbish HV-AO-272 using the vendor recommended grease compatible with the ethylene propylene actuator piston seals, completed in September 2013; and | ||
: (2) update Station Procedure 7.2.51.7, | : (2) update Station Procedure 7.2.51.7, Bettis Models N521-SR and N721-SR Actuator Maintenance, Revision 4, to incorporate vendor recommended grease. This procedure was initially issued in 1995, using the incompatible petroleum based grease. | ||
During the inspectors review of the evaluation documented in Condition Report CR-CNS-2013-02324, and control room emergency system health reports, the inspectors noted that HV-AO-272 degraded strokes times had begun in the 2007 timeframe. The inspectors determined that the incompatible grease was introduced in the 2007 timeframe, after the initial issue date for Station Procedure 7.2.51.7. | |||
The inspectors also noted that HV-AO-272 was refurbished in 2009, for a failed actuator and again in 2011, due to degrading strokes times. The inspectors questioned if the use of petroleum based grease was evaluated in accordance with station procedures and if there was a programmatic issue with the station work planning process. To capture this concern in the stations corrective action program, the licensee initiated Condition Report CR-CNS-2013-04327. | |||
The licensee subsequently performed an Apparent Cause Evaluation, and documented it in Condition Report CR-CNS-2013-04327. Their evaluation determined that the contributing cause for the incompatible grease being used during the rebuild of HV-AO-272 in 2007 was that the requirements of Station Procedure 0.40.4, Revision 5, were not followed. Specifically, the procedure required work order materials to be determined adequate for the application by using controlled documents and that mis-matches in material/equipment safety classifications are resolved. This error was not detected and subsequently repeated during planning of the 2009 and 2011 corrective maintenance work orders for HV-AO-272. To capture this concern in the stations corrective action program, the licensee initiated Condition Report CR-CNS-2013-05177. | |||
The evaluation, documented in Condition Report CR-CNS-2013-05177, determined that engineering had developed 15 generic Quality (Q) number evaluations, because in the past work was held up while developing specific Q number evaluation for miscellaneous parts. These generic Q numbers covered items such as terminal boxes, conduit, gaskets, and thread lubricants for O-ring. Additionally, Station Procedure 0-CNS-WM-105, Planning, Revision 6, called for station planners to use these generic Q numbers to resolve mis-matches in safety classifications of materials used in work orders, which superseded Station Procedure 0.40.4. Therefore, the station concluded that this is a legacy issue and it appears station personnel followed the Station Procedure 0.40.4 and used generic Q number Q-Gen-002 that allowed use of the incompatible grease since it was listed in Station Procedure 7.2.51.7. The inspectors noted this was contrary to the contributing cause documented in Condition Report CR-CNS-2013-04327. | |||
The inspectors reviewed the procedures, work orders and the generic Q number evaluation. During this review the inspectors determined that the licensee had failed to follow the requirements of Station Procedures 0.40.4 and 0-CNS-WW-105. Inspectors determined that the planners had used Station Procedures 0.40.4 and 0-CNS-WW-105 to identify that Q-GEN-002 existed, but had failed to review Q-GEN-002 to determine if there were any restrictions associated with its use. Specifically, the instructions limited the use of O-ring lubricants on environmental qualified components to Parker Super O-ring lubricant. The use of any other O-ring lubricant shall be approved by engineering and it did not authorize the use of petroleum based grease with the ethylene propylene actuator piston seals for HV-AO-272. | |||
=====Analysis.===== | =====Analysis.===== | ||
The failure to ensure the correct materials were installed in the control room emergency filtration system air operated valve HV-AO-272 was a performance deficiency.

Specifically, inspectors had determined that the licensee was not appropriately monitoring the roof drains to ensure that their performance or condition had been demonstrated to be effectively controlled. The licensee entered this issue into the corrective action program as Condition Report CR-CNS-2012-05993. The licensee subsequently moved the roof drains into 50.65(a)(1) status and initiated Condition Report CR-CNS-2013-00466 to develop an (a)(1) action plan. | ||

Inspectors noted that 10 CFR 50.65(a)(2) states, in part, that monitoring as specified in 10 CFR 50.65(a)(1) is not required where it has been demonstrated that the performance of a system is being effectively controlled through the performance of appropriate preventive maintenance, such that the system remains capable of performing its intended function. Since NCV 05000298/2012005-02 had been issued because the licensee had failed to adequately monitor the performance of the drains, inspectors determined that the licensee was required to comply with the actions of paragraph (a)(1) which required the establishment of goals and monitoring the drains performance against these goals. Furthermore, inspectors reviewed Procedure EN-DC-206 and noted that Section 5.2[9] provided that a structure, system, or component within the scope of the Maintenance Rule that has not exhibited a monitoring failure may be classified as (a)(1) at management's discretion. However, the section did not alleviate the need to establish goals and monitor against these goals.

Inspectors questioned the | Inspectors questioned the licensees operability determination. Specifically, if the currently installed relay was part of the same equipment batch as the failed relay, and the failure was caused by a manufacturing defect, why there was assurance that the same condition was not present in the installed relay. Based on this, inspectors determined the licensees operability evaluation was not adequate to fully establish the pumps operability. Inspectors informed the licensee of their concerns. To capture this concern, in the stations corrective action program, the licensee initiated Condition Report CR-CNS-2013-06455. | ||
As an immediate action, the licensee completed an operability evaluation that considered the | As an immediate action, the licensee completed an operability evaluation that considered the relays hours of operation and burn-in requirement. The licensee determined residual heat removal pump B had been started eleven times with a combined run time of approximately 83 hours with no discrepancies noted. From the 83 hours of successful run time with no indication of failures and no vendor recommended requirement to perform a burn-in, the licensee concluded the residual heat removal pump B, and its associated auxiliary functions, remained operable. | ||
The inspectors determined that the apparent cause of this finding was that the licensee had failed to use conservative assumptions and failed to adopt a requirement to demonstrate that the proposed action was safe in order to proceed, rather than a requirement to demonstrate that it was unsafe in order to disapprove the action. The licensee had failed to validate that the failure of the relay installed on June 2, 2013, would have no adverse effect on nuclear safety and considered it acceptable to replace the relay at the next available opportunity as documented in the apparent cause evaluation extent of condition and Condition Report CR-CNS-2013-06203. | The inspectors determined that the apparent cause of this finding was that the licensee had failed to use conservative assumptions and failed to adopt a requirement to demonstrate that the proposed action was safe in order to proceed, rather than a requirement to demonstrate that it was unsafe in order to disapprove the action.

Specifically, the | Specifically, the licensees implementation of an alternate staging area for emergency response organization staff normally assigned to onsite emergency response facilities at the Auburn, Nebraska, Offsite Response Facility would have conflicted with the response of the licensees Joint Information Center. | ||
The Cooper Nuclear | The Cooper Nuclear Stations Auburn, Nebraska, Offsite Response Facility normally houses the licensees Emergency Operations Facility and Joint Information Center. The inspector reviewed the licensees plans for locating an alternative staging area at the Offsite Response Facility for emergency response organization personnel normally assigned to onsite emergency response facilities. The inspector determined the licensee had means to inform all emergency response organization staff to report to the Offsite Response Facility as needed, and had appropriately trained staff about how they would be notified to report to the alternate location. However, the licensee had not described the alternate staging area in Emergency Plan, Revision 63, or prepared procedures or other guidance for implementing the staging area. | ||
The inspector visited the Offsite Response Facility on June 27, 2013, to determine whether licensee plans could be effectively implemented. Licensee representatives described that relocated Technical Support Center staff would be placed in working rooms in the Joint Information Center, and relocated Operations Support Center staff would be placed in the building lobby and adjacent press work room.

This finding is more than minor because it affected the facilities and equipment emergency preparedness cornerstone attribute (maintenance, surveillance, and testing of facilities). The finding had a credible impact on the cornerstone objective because the licensees ability to implement adequate measures to protect the health and safety of the public during a radiological emergency would be affected if it could not stage personnel to respond to the site during events involving hostile action, or in other events in which access to the site is impeded. The ability to communicate measures to protect the health and safety of the public would also be affected if there were impediments to Joint Information Center operations. The finding was associated with a violation of NRC requirements. This finding was evaluated using IMC 0609, Appendix B, Emergency Preparedness Significance Determination Process and was determined to be of very low safety significance (Green) because it was a failure to comply with NRC requirements and was not a loss of planning standard function. The planning standard was not lost because the finding affected an alternate facility and the impediments would not have precluded the Joint Information Center from fulfilling its emergency functions. This finding was assigned a cross-cutting aspect in the area of Human Performance associated with the resources component because the licensee did not provide and maintain adequate emergency facilities, and the finding is reflective of current performance [H.2(d)]. | ||

Appendix E to Part 50, Part IV.E(8)(d), requires a licensee to have by June 20, 2012, a facility that would be accessible even if the site is under threat of or experiencing hostile action to function as a staging area for augmentation. The Cooper Nuclear Station Emergency Plan, Revision 63, Section 7.2.4, requires a Joint Information Center.

UNITED STATE S NUC LEAR REGULATOR Y C OMMI SSI ON ber 12, 2013
SUBJECT:
COOPER NUCLEAR STATION - NRC INTEGRATED INSPECTION REPORT 05000298/2013004
Dear Mr. Limpias:
On September 22, 2013, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at your Cooper Nuclear Station. On October 7, 2013, the NRC inspectors discussed the results of this inspection with you and other members of your staff. Inspectors documented the results of this inspection in the enclosed inspection report.
NRC inspectors documented four findings of very low safety significance (Green) in this report.
All of these findings were determined to involve violations of NRC requirements. Further, inspectors documented a licensee-identified violation, which was determined to be of very low safety significance, in this report. The NRC is treating these violations as non-cited violations (NCVs) consistent with Section 2.3.2.a of the Enforcement Policy.
If you contest the violations or significance of these NCVs, you should provide a response within 30 days of the date of this inspection report, with the basis for your denial, to the U.S. Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington DC, 20555-0001; with copies to the Regional Administrator, Region IV; the Director, Office of Enforcement, U.S. Nuclear Regulatory Commission, Washington DC, 20555-0001; and the NRC resident inspector at the Cooper Nuclear Station.
If you disagree with a cross-cutting aspect assignment 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 Cooper Nuclear Station. In accordance with Title 10 of the Code of Federal Regulations (10 CFR) 2.390, Public Inspections, Exemptions, Requests for Withholding, a copy of this letter, its enclosure, and your response (if any) will be available electronically for public inspection in the NRCs Public Document Room or from the Publicly Available Records (PARS) component of the NRC's Agencywide Documents Access and Management System (ADAMS). ADAMS is accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).
Sincerely,
/RA/

SUMMARY OF FINDINGS
IR 05000298/2013004; 06/23/2013 -09/22/2013; Cooper Nuclear Station; Integrated Resident &
Regional Report; Equipment Alignment, Maintenance Effectiveness, Operability Determinations
& Functionality Assessments, and Maintenance of Emergency Preparedness The report covered a 3-month period of inspection by resident inspectors and announced baseline inspections by region-based inspectors. Four Green, non-cited violations of significance 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.
NRC-Identified Findings and Self-Revealing Findings
Cornerstone: Mitigating Systems
- Green.
The inspectors identified a non-cited violation of 10 CFR Part 50,
Appendix B, Criterion III, Design Control, associated with the licensees failure to ensure the correct materials were installed in the control room emergency filtration system air operated valve HV-AO-272. Specifically, incompatible grease was introduced into the valve causing increased friction and degrading stroke times. The licensee entered this deficiency into their corrective action program for resolution as Condition Report CR-CNS-2013-04327.
The failure to ensure the correct materials were installed in the control room emergency filtration system air operated valve HV-AO-272 was a performance deficiency. This performance deficiency was more than minor, and therefore a finding, because it was associated with the equipment performance attribute of the Mitigating Systems Cornerstone. Specifically, the licensee introduced an incompatible grease into HV-AO-272 causing increased friction and degrading stroke times, thereby affecting the associated objective to ensure availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. The inspectors evaluated the finding using Inspection Manual Chapter 0609, Appendix A, The Significance Determination Process (SDP) For Findings At-Power, and determined that the finding was of very low safety significance (Green) because the finding: (1) was not a deficiency affecting the design and qualification of a mitigating structure, system, or component, and did not result in a loss of operability or functionality; (2) did not represent a loss of system and/or function; (3) did not represent an actual loss of function of at least a single train for longer than its technical specification allowed outage time, or two separate safety systems out-of-service for longer than their technical specification allowed outage time; and (4) did not represent an actual loss of function of one or more nontechnical specification trains of equipment designated as high safety-significance in accordance with the licensees maintenance rule program. The finding has a cross-cutting aspect in the area of human performance associated with work practices component because the licensee personnel failed to define and effectively communicate expectations regarding procedural compliance and to ensure that personnel followed procedures H.4(b)(Section 1R04).
- Green.
The inspectors identified a non-cited violation of 10 CFR 50.65,
Requirements for monitoring the effectiveness of maintenance at nuclear power plants, associated with the licensees failure to establish goals per paragraph (a)(1), and monitor the performance of the drains for the reactor building, control building, and diesel generator building against these goals following the determination that the licensee had failed to adequately monitor the performance of the drains. Specifically, following the identification of NCV 05000298/2012005-02, Failure to Adequately Monitor the Performance of Roof Drains in Inspection Report 05000298/2012005, the license moved the systems to 50.65(a)(1) status but failed to establish goals as required. The licensee entered this issue into their corrective action program for resolution as Condition Report CR-CNS-2013-06590.
The failure to establish goals for systems in 50.65(a)(1) status was a performance deficiency. This performance deficiency was more than minor, and therefore a finding, because it was associated with the protection against the external factors attribute of the Mitigating Systems Cornerstone. Specifically, the failure to establish goals and monitor the drains for the reactor building, control building, and diesel generator buildings against these goals could result the failure to detect deteriorating performance, thereby affecting the associated cornerstone objective to ensure availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. The inspectors evaluated the finding using Inspection Manual Chapter 0609,
Appendix A, The Significance Determination Process (SDP) For Findings At-Power, and determined that the finding was of very low safety significance (Green) because the finding: (1) was not a deficiency affecting the design and qualification of a mitigating structure, system, or component, and did not result in a loss of operability or functionality; (2) did not represent a loss of system and/or function; (3) did not represent an actual loss of function of at least a single train for longer than its technical specification allowed outage time, or two separate safety systems out-of-service for longer than their technical specification allowed outage time; and (4) did not represent an actual loss of function of one or more nontechnical specification trains of equipment designated as high safety-significance in accordance with the licensees maintenance rule program. The finding has a cross-cutting aspect in the area of human performance associated with the work practices component because the licensee failed to define and effectively communicate expectations regarding procedural compliance and personnel follow procedures. Specifically, licensee personnel failed to follow procedural guidance that required goals and monitoring when the systems were placed in 50.65(a)(1) monitoring H.4(b)(Section 1R12).
- Green.
The inspectors identified a non-cited violation of 10 CFR Part 50,
Appendix B, Criterion V, Instructions, Procedures, Drawings, associated with the licensees failure to follow Station Procedure 0.5OPS, Operations Review of Condition Reports/Operability Determination, and properly document the basis for operability when degrading or nonconforming condition was identified.
Specifically, the licensee failed to consider that failure of a relay prevented residual heat removal Division II minimum flow valve RHR-MOV-16B from opening automatically when residual heat removal pump B flow was lowered, and concluded a failure of the replacement relay would not have an adverse effect on nuclear safety. The licensee entered this deficiency into their corrective action program for resolution as Condition Report CR-CNS-2013-06455.
The failure to properly assess and document the basis for operability when a degraded or nonconforming condition was identified was a performance deficiency. The performance deficiency was more than minor, and therefore a finding, because it was associated with the equipment performance attribute of the Mitigating Systems Cornerstone and affected the cornerstone objective.
Specifically, the licensees failure to properly document and assess the basis for operability resulted in a condition of unknown operability for a degraded nonconforming system, thereby affecting the associated objective to ensure availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. The inspectors evaluated the finding using Inspection Manual Chapter 0609, Appendix A, The Significance Determination Process (SDP) For Findings At-Power, and determined that the finding was of very low safety significance (Green) because the finding: (1) was not a deficiency affecting the design and qualification of a mitigating structure, system, or component, and did not result in a loss of operability or functionality; (2) did not represent a loss of system and/or function; (3) did not represent an actual loss of function of at least a single train for longer than its technical specification allowed outage time, or two separate safety systems out-of-service for longer than their technical specification allowed outage time; and (4) did not represent an actual loss of function of one or more nontechnical specification trains of equipment designated as high safety-significance in accordance with the licensees maintenance rule program. The finding has a cross-cutting aspect in the area of human performance associated with the decision-making component because the licensee did not adopt a requirement to demonstrate that the proposed action was safe in order to proceed, rather than a requirement to demonstrate that it was unsafe in order to disapprove the action H.1(b)
(Section 1R15).
Cornerstone: Emergency Preparedness
- Green.
The inspector identified a non-cited violation of 10 CFR Part 50,
Appendix E, IV.E(8)(d), for failure to implement by June 20, 2012, a facility that would be accessible even if the site is under threat of or experiencing hostile action to function as a staging area for augmentation. Specifically, the licensees implementation of a staging area at the Auburn, Nebraska, Offsite Response Facility would have created impediments to effective Joint Information Center operations.
The failure to provide a facility accessible when the site is experiencing or under threat of hostile action is a performance deficiency within the licensees ability to foresee and correct. This finding is more than minor because it affected the facilities and equipment attribute of the Emergency Preparedness Cornerstone.
The finding is of very low safety significance because it was a failure to comply with NRC requirements and was not a loss of planning standard function. The planning standard function was not lost because the finding affected an alternate facility and the impediments would not have precluded the Joint Information Center from fulfilling its emergency functions. The licensee has entered this issue into their corrective action system as Condition Report CR-CNS-2013-04765. This finding was assigned a cross-cutting aspect in the area of human performance associated with the resource component because the licensee did not provide and maintain adequate emergency facilities, and the finding is reflective of current performance H.2(d) (Section 1EP5).
Licensee-Identified Violations
A violation of very low safety significance that was identified by the licensee has been reviewed by the inspectors. Corrective actions taken or planned by the licensee have been entered into the licensees corrective action program. This violation and associated corrective action tracking number is listed in Section 4OA7 of this report.
PLANT STATUS
The Cooper Nuclear Station began the inspection period at full power on June 23, 2013. On June 29, 2013, the licensee lowered power to approximately 30 percent to effect repairs to main feedwater heater 4B. On June 30, 2013, while increasing power the licensee discovered a stem to disk separation of main turbine control valve 3. The licensee held power at 95 percent due to this issue. On July 20, 2013, the licensee lowered power to approximately 55 percent to effect repairs to main turbine control valve 3. On July 22, 2013, the licensee increased power to 100 percent where it remained for the rest of the reporting period.

1R01 Adverse Weather Protection
.1 Readiness for Seasonal Extreme Weather Conditions
a. Inspection Scope
The inspectors reviewed the licensees adverse weather procedures for seasonal high temperatures and seasonal cold temperatures, and evaluated the licensees implementation of these procedures. The inspectors verified that prior to the onset of the hot and cold weather, the licensee had corrected weather-related equipment deficiencies identified during the previous summer and winter seasons.
The inspectors reviewed plant design features and the procedures used by plant personnel to mitigate or respond to adverse weather conditions. The inspectors verified that operator actions specified in these procedures maintained readiness of essential equipment and systems to preclude weather induced initiating events. The inspectors reviewed the Updated Final Safety Analysis Report and the performance requirements for selected systems to ensure that selected system components would reasonably remain functional if challenged by adverse weather. The inspectors reviews focused specifically on the following plant systems:
- September 6, Diesel generators 1 and 2 The inspectors also reviewed corrective action program items to verify that the licensee was identifying adverse weather issues at an appropriate threshold and entering them into its corrective action program for resolution. Specific documents reviewed during this inspection are listed in the attachment.
These activities constitute completion of one sample to evaluate the readiness for seasonal adverse weather, as defined in Inspection Procedure 71111.01-05.
b. Findings

.2 Readiness for Impending Adverse Weather Conditions
a. Inspection Scope
On September 6, 2013, the inspectors walked down the service water discharge piping because its safety-related function could be affected, as a result of high winds, tornado-generated missiles, or the loss of offsite power. The inspectors evaluated the plant staffs preparations against the sites procedures and determined that the staffs actions were adequate. During the inspection, the inspectors focused on plant design features and the licensees procedures to respond to tornados and high winds. The inspectors also toured the plant grounds to look for any loose debris that could become missiles during a tornado. The inspectors evaluated operator staffing and accessibility of controls and indications for those systems required to control the plant. Additionally, the inspectors reviewed the Updated Final Safety Analysis Report and performance requirements for the system selected for inspection, and verified that operator actions were appropriate as specified by plant-specific procedures. The inspectors also reviewed a sample of corrective action program items to verify that the licensee had identified adverse weather issues at an appropriate threshold and entered them into the corrective action program for resolution. Specific documents reviewed during this inspection are listed in the attachment.
These activities constitute completion of one sample of readiness for impending adverse weather conditions, as defined in Inspection Procedure 71111.01-05.
b. Findings

1R04 Equipment Alignment
.1 Partial Walkdown
a. Inspection Scope
The inspectors performed partial system walkdowns of the following risk-significant systems:
- July 19, Core spray B and residual heat removal B suction strainer
- August 7, Diesel generator 1 starting air
- September 11, Service water Division 1 strainer and pumps The inspectors selected these systems based on their risk significance relative to the reactor safety cornerstones at the time they were inspected, while considering out of service time, inoperable or degraded conditions, recent system outages, and maintenance, modification, and testing. 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, the 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 defined in Inspection Procedure 71111.04-05
b. Findings
Introduction.
The inspectors identified a Green non-cited violation of 10 CFR Part 50, Appendix B, Criterion III, Design Control, associated with the licensees failure to ensure the correct materials were installed in the control room emergency filtration system air operated valve HV-AO-272.
Description.
The inspectors selected Condition Report CR-CNS-2013-02324, which had been initiated due to degraded stroke times for HV-AO-272, for review based on the valves risk significance and previously identified issues with degrading stroke times for the valve. The licensees evaluation determined the likely cause of the degrading stroke times for HV-AO-272 was the use of petroleum based grease, which was not compatible with the ethylene propylene actuator piston seals for HV-AO-272. The petroleum based grease degrades the seal material, causing swelling which resulted in increased actuator friction and longer closing stroke times. The licensee initiated the following corrective actions based on the conclusion of their evaluation documented in Condition Report CR-CNS-2013-02324:
- (1) refurbish HV-AO-272 using the vendor recommended grease compatible with the ethylene propylene actuator piston seals, completed in September 2013; and
- (2) update Station Procedure 7.2.51.7, Bettis Models N521-SR and N721-SR Actuator Maintenance, Revision 4, to incorporate vendor recommended grease. This procedure was initially issued in 1995, using the incompatible petroleum based grease.
During the inspectors review of the evaluation documented in Condition Report CR-CNS-2013-02324, and control room emergency system health reports, the inspectors noted that HV-AO-272 degraded strokes times had begun in the 2007 timeframe. The inspectors determined that the incompatible grease was introduced in the 2007 timeframe, after the initial issue date for Station Procedure 7.2.51.7.
The inspectors also noted that HV-AO-272 was refurbished in 2009, for a failed actuator and again in 2011, due to degrading strokes times. The inspectors questioned if the use of petroleum based grease was evaluated in accordance with station procedures and if there was a programmatic issue with the station work planning process. To capture this concern in the stations corrective action program, the licensee initiated Condition Report CR-CNS-2013-04327.
The licensee subsequently performed an Apparent Cause Evaluation, and documented it in Condition Report CR-CNS-2013-04327. Their evaluation determined that the contributing cause for the incompatible grease being used during the rebuild of HV-AO-272 in 2007 was that the requirements of Station Procedure 0.40.4, Revision 5, were not followed. Specifically, the procedure required work order materials to be determined adequate for the application by using controlled documents and that mis-matches in material/equipment safety classifications are resolved. This error was not detected and subsequently repeated during planning of the 2009 and 2011 corrective maintenance work orders for HV-AO-272. To capture this concern in the stations corrective action program, the licensee initiated Condition Report CR-CNS-2013-05177.
The evaluation, documented in Condition Report CR-CNS-2013-05177, determined that engineering had developed 15 generic Quality (Q) number evaluations, because in the past work was held up while developing specific Q number evaluation for miscellaneous parts. These generic Q numbers covered items such as terminal boxes, conduit, gaskets, and thread lubricants for O-ring. Additionally, Station Procedure 0-CNS-WM-105, Planning, Revision 6, called for station planners to use these generic Q numbers to resolve mis-matches in safety classifications of materials used in work orders, which superseded Station Procedure 0.40.4. Therefore, the station concluded that this is a legacy issue and it appears station personnel followed the Station Procedure 0.40.4 and used generic Q number Q-Gen-002 that allowed use of the incompatible grease since it was listed in Station Procedure 7.2.51.7. The inspectors noted this was contrary to the contributing cause documented in Condition Report CR-CNS-2013-04327.
The inspectors reviewed the procedures, work orders and the generic Q number evaluation. During this review the inspectors determined that the licensee had failed to follow the requirements of Station Procedures 0.40.4 and 0-CNS-WW-105. Inspectors determined that the planners had used Station Procedures 0.40.4 and 0-CNS-WW-105 to identify that Q-GEN-002 existed, but had failed to review Q-GEN-002 to determine if there were any restrictions associated with its use. Specifically, the instructions limited the use of O-ring lubricants on environmental qualified components to Parker Super O-ring lubricant. The use of any other O-ring lubricant shall be approved by engineering and it did not authorize the use of petroleum based grease with the ethylene propylene actuator piston seals for HV-AO-272.
Analysis.
The failure to ensure the correct materials were installed in the control room emergency filtration system air operated valve HV-AO-272 was a performance deficiency. This performance deficiency was more than minor, and therefore a finding, because it was associated with the equipment performance attribute of the Mitigating Systems Cornerstone. Specifically, the licensee introduced an incompatible grease into HV-AO-272 causing increased friction and degrading stroke times, thereby affecting the associated cornerstone objective to ensure availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. The inspectors evaluated the finding using Inspection Manual Chapter 0609, Appendix A, The Significance Determination Process (SDP) For Findings At-Power, and determined that the finding was of very low safety significance (Green) because the finding:
- (1) was not a deficiency affecting the design and qualification of a mitigating structure, system, or component, and did not result in a loss of operability or functionality;
- (2) did not represent a loss of system and/or function;
- (3) did not represent an actual loss of function of at least a single train for longer than its technical specification allowed outage time, or two separate safety systems out-of-service for longer than their technical specification allowed outage time; and
- (4) did not represent an actual loss of function of one or more nontechnical specification trains of equipment designated as high safety-significance in accordance with the licensees maintenance rule program. The finding has a cross-cutting aspect in the area of human performance associated with the work practices component because the licensee personnel failed to define and effectively communicate expectations regarding procedural compliance and to ensure that personnel followed procedures H.4(b).
Enforcement.
Title 10 CFR Part 50, Appendix B, Criterion III, Design Control, states, in part, that measures shall be established to assure the design bases are correctly translated into specifications, drawing, procedures, and instructions. Contrary to the above, from November 2007, to September 2013, the licensee failed to establish measures to assure design bases was correctly translated into specification.
Specifically, measures established by the licensee failed to ensure vendor recommended grease was correctly translated into specification for the control room emergency filter system safety-related air operated valves. This violation is being treated as a non-cited violation (NCV), consistent with Section 2.3.2.a of the Enforcement Policy. The violation was entered into the licensees correction action program as Condition Report CR-CNS-2013-04327. (NCV 05000298/2013004-01, Failure to Maintain Design Control of the Control Room Emergency Filter System Safety-related Air Operated Valve)
.2 Complete Walkdown
a. Inspection Scope
On September 13, 2013, the inspectors performed a complete system alignment inspection of the Division II 125 Vdc and 250 Vdc system to verify the functional capability of the system. The inspectors selected this system based on risk-informed insights from site-specific risk studies together with other factors, such as engineering analysis and judgment, operating experience, performance history, current plant mode, and/or previous walkdowns. The inspectors reviewed plant procedures, including abnormal and emergency drawings, the Updated Safety Analysis Report, and vendor manuals to determine the correct lineup. The inspectors also visually inspected the system to review mechanical and electrical equipment line ups, electrical power availability, system pressure and temperature indications, as appropriate, component labeling, component lubrication, component and equipment cooling, hangers and supports, and the operability of support systems. Furthermore, the inspectors ensured that ancillary equipment or debris did not interfere with equipment operation. The inspectors also reviewed a sample of past and outstanding work orders to determine whether any deficiencies significantly affected the system function. In addition, the inspectors reviewed the corrective action program database to ensure that system equipment-alignment problems were being identified and appropriately resolved.
Specific documents reviewed during this inspection are listed in the attachment.
These activities constitute completion of one complete system walkdown sample, as defined in Inspection Procedure 71111.04-05.
b. Findings
No findings were identified.
1R05 Fire Protection
.1 Quarterly Fire Inspection Tours
a. Inspection Scope
The inspectors conducted fire protection walkdowns that were focused on availability, accessibility, and the condition of firefighting equipment in the following risk-significant plant areas:
- July 9, Battery room 1A, Fire Area IV(A), Zone 8E
- July 9, DC switchgear room 1A, Fire Area IV(A), Zone 8H
- July 9, Diesel generator room 1A, Fire Area IX, Zone 14A
- July 9, Diesel generator 1A diesel oil day tank room, Fire Area IX, Zone 14C 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; had effectively maintained fire detection and suppression capability; had 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, and verified that adequate compensatory measures were put in place by the licensee for out of service, degraded, or inoperable fire protection equipment systems or features. The inspectors also verified that minor issues identified during the inspection were entered into the licensees corrective action program.
These activities constitute completion of four quarterly fire-protection inspection samples, as defined in Inspection Procedure 71111.05-05.
b. Findings
No findings were identified.
.2 Annual Fire Protection Drill Observation
a. Inspection Scope
On August 29, 2013, the inspectors observed a fire brigade activation in the 903 feet corrider of the Control Building. The observation evaluated the readiness of the plant fire brigade to fight fires. The inspectors verified that the licensee staff identified deficiencies, openly discussed them in a self-critical manner at the drill debrief, and took appropriate corrective actions. Specific attributes evaluated were:
- (1) proper wearing of turnout gear and self-contained breathing apparatus;
- (2) proper use and layout of fire hoses;
- (3) employment of appropriate fire fighting techniques;
- (4) sufficient firefighting equipment brought to the scene;
- (5) effectiveness of fire brigade leader communications, command, and control;
- (6) search for victims and propagation of the fire into other plant areas;
- (7) smoke removal operations;
- (8) utilization of preplanned strategies;
- (9) adherence to the preplanned drill scenario; and
- (10) drill objectives.
These activities constitute completion of one annual fire-protection inspection sample, as defined in Inspection Procedure 71111.05-05.
b. Findings
No findings were identified.
1R06 Flood Protection Measures
a. Inspection Scope
The inspectors reviewed the Updated Final Safety Analysis Report, the flooding analysis, and plant procedures to assess susceptibilities involving internal flooding; reviewed the corrective action program to determine if licensee personnel identified and corrected flooding problems; inspected underground bunkers/manholes to verify the adequacy of sump pumps, level alarm circuits, cable splices subject to submergence, and drainage for bunkers/manholes; and verified that operator actions for coping with flooding can reasonably achieve the desired outcomes. The inspectors also inspected the area listed below to verify the adequacy of equipment seals located below the flood line, floor and wall penetration seals, watertight door seals, common drain lines and sumps, sump pumps, level alarms, control circuits, and temporary or removable flood barriers.
Specific documents reviewed during this inspection are listed in the attachment.
- August 19, Manhole ZHH-44 These activities constitute completion of one bunker/manhole sample, as defined in Inspection Procedure 71111.06-05.

a. Inspection Scope
On July 17, 2013, the inspectors observed a crew of licensed operators in the plants simulator during requalification training. The inspectors assessed the following areas:
- Licensed operator performance
- The ability of the licensee to administer the evaluations and the quality of the training provided
- The modeling and performance of the control room simulator
- The quality of post-scenario critiques
- Follow-up actions taken by the licensee for identified discrepancies These activities constitute completion of one quarterly licensed operator requalification program sample, as defined in Inspection Procedure 71111.11-05.
b. Findings

- July 2, Division II 125 and 250 Vdc
- September 13, Division II residual heat removal system pump B maintenance rule function failure evaluations
- September 22, Diesel generator 2 jacket water system 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)
- Characterizing system reliability issues for performance
- Charging unavailability for performance
- Trending key parameters for condition monitoring
- Ensuring proper classification in accordance with 10 CFR 50.65(a)(1) or -(a)(2)
- Verifying appropriate performance criteria for structures, systems, and components classified as having an adequate demonstration of performance through preventive maintenance, as described in 10 CFR 50.65(a)(2), or as requiring the establishment of appropriate and adequate goals and corrective actions for systems classified as not having adequate performance, as described in 10 CFR 50.65(a)(1)
The inspectors assessed performance issues with respect to the reliability, availability, and condition monitoring of the system. In addition, the inspectors verified maintenance effectiveness issues were appropriately handled by a screening and identification process and that issues were entered into the corrective action program with the appropriate significance characterization. Specific documents reviewed during this inspection are listed in the attachment.
These activities constitute completion of three maintenance effectiveness samples, as defined in Inspection Procedure 71111.12-05.
b. Findings
Introduction.
The inspectors identified a Green non-cited violation of 10 CFR 50.65, Requirements for monitoring the effectiveness of maintenance at nuclear power plants, associated with the licensees failure to establish goals per paragraph (a)(1), and monitor the performance of the drains for the reactor building, control building, and diesel generator building against these goals following the determination that the licensee had failed to adequately monitor the performance of the drains.
Description.
On February 14, 2013, the NRC issued Inspection Report 05000298/2012005 (ML13045A297), which documented non-cited violation NCV 05000298/2012005-02, Failure to Adequately Monitor the Performance of Roof Drains, for the licensees failure to adequately monitor the performance of roof drains for the reactor building, control building, and diesel generator building. Specifically, inspectors had determined that the licensee was not appropriately monitoring the roof drains to ensure that their performance or condition had been demonstrated to be effectively controlled. The licensee entered this issue into the corrective action program as Condition Report CR-CNS-2012-05993. The licensee subsequently moved the roof drains into 50.65(a)(1) status and initiated Condition Report CR-CNS-2013-00466 to develop an (a)(1) action plan.
On August 20, 2013, while attending a scheduled meeting of the stations maintenance rule expert panel, inspectors reviewed the licensees (a)(1) action plan documented in Condition Report CR-CNS-2013-00466. During this review inspectors noted that the licensee had not established goals with monitoring criteria for the roof drains. Instead, the licensee stated that Station Procedure EN-DC-206, Maintenance Rule (A)(1)
Process, Revision 1, Section 5.2[9] allowed the system to be placed in (a)(1) monitoring without goals per System Engineering Management discretion.
Inspectors noted that 10 CFR 50.65(a)(2) states, in part, that monitoring as specified in 10 CFR 50.65(a)(1) is not required where it has been demonstrated that the performance of a system is being effectively controlled through the performance of appropriate preventive maintenance, such that the system remains capable of performing its intended function. Since NCV 05000298/2012005-02 had been issued because the licensee had failed to adequately monitor the performance of the drains, inspectors determined that the licensee was required to comply with the actions of paragraph (a)(1) which required the establishment of goals and monitoring the drains performance against these goals. Furthermore, inspectors reviewed Procedure EN-DC-206 and noted that Section 5.2[9] provided that a structure, system, or component within the scope of the Maintenance Rule that has not exhibited a monitoring failure may be classified as (a)(1) at management's discretion. However, the section did not alleviate the need to establish goals and monitor against these goals.
Section 5.2[9](f) directed that the (a)(1) action plan preparation proceed per Section 5.3 of the procedure, and Section 5.3[4](h) directed the development of performance goals and Section 5.3[4](i) directed monitoring against these goals.
Inspectors determined that the licensee had failed to establish goals, and monitor performance against these goals, for the roof drains on the reactor building, control building, and diesel generator building after placing them in 50.65(a)(1) status.
Inspectors informed the licensee of their concern and the licensee entered this issue into their corrective action program for resolution as Condition Report CR-CNS-2013-06590.
Analysis.
The failure to establish goals for systems in 50.65(a)(1) status was a performance deficiency. This performance deficiency was more than minor, and therefore a finding, because it was associated with the protection against the external factors attribute of the Mitigating Systems Cornerstone. Specifically, the failure to establish goals and monitor the drains for the reactor building, control building, and diesel generator buildings against these goals could result in the failure to detect deteriorating performance, thereby affecting the associated cornerstone objective to ensure availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. The inspectors evaluated the finding using Inspection Manual Chapter 0609, Appendix A, The Significance Determination Process (SDP) For Findings At-Power, and determined that the finding was of very low safety significance (Green) because the finding:
- (1) was not a deficiency affecting the design and qualification of a mitigating structure, system, or component, and did not result in a loss of operability or functionality;
- (2) did not represent a loss of system and/or function;
- (3) did not represent an actual loss of function of at least a single train for longer than its technical specification allowed outage time, or two separate safety systems out-of-service for longer than their technical specification allowed outage time; and
- (4) did not represent an actual loss of function of one or more nontechnical specification trains of equipment designated as high safety-significance in accordance with the licensees maintenance rule program. The finding has a cross-cutting aspect in the area of human performance associated with the work practices component because the licensee failed to define and effectively communicate expectations regarding procedural compliance and personnel follow procedures. Specifically, licensee personnel failed to follow procedural guidance that required goals and monitoring when the systems were placed in 50.65(a)(1) monitoring H.4(b).
Enforcement.
Title 10 CFR 50.65(a)(1) requires, in part, that, holders of an operating license shall monitor the performance or condition of structures, systems, or components within the scope of the monitoring program against licensee established goals in a manner sufficient to provide reasonable assurance that such structures, systems, or components are capable of fulfilling their intended safety functions. Contrary to the above, between January 21, and September 19, 2013, the licensee failed to establish goals in a manner sufficient to provide reasonable assurance that structures, systems or components are capable of fulfilling their intended safety function. Specifically, the licensee failed to establish goals in a manner sufficient to provide reasonable assurance that the roof drains for the reactor building, control building, and diesel generator building are capable of fulfilling their intended safety functions.his violation is being treated as a non-cited violation, consistent with Section 2.3.2.a of the Enforcement Policy. The violation was entered into the licensees correction action program as Condition Report CR-CNS-2013-06455. (NCV 05000298/2013004-02, Failure to Establish Goals and Monitor for the Roof Drain Systems)
1R13 Maintenance Risk Assessments and Emergent Work Control
a. Inspection Scope
The inspectors reviewed licensee personnel's evaluation and management of plant risk for the maintenance and emergent work activities affecting risk-significant and safety-related equipment listed below to verify that the appropriate risk assessments were performed prior to removing equipment for work:
- July 2, Residual heat removal service water Division I
- July 18, Residual heat removal Division II valves RHR-MO-16B and -26B Appendix R modifications
- August 30, Diesel generator 2 availability during core spray time delay functional surveillance
- September 6, Service water Division I and II discharge pipe repair
- September 19, Crane operation near loaded spent fuel horizontal storage modules The inspectors selected these activities based on potential risk significance relative to the reactor safety cornerstones. As applicable for each activity, the inspectors verified that licensee personnel performed risk assessments as required by 10 CFR 50.65(a)(4)and that the assessments were accurate and complete. When licensee personnel performed emergent work, the inspectors verified that the licensee personnel promptly assessed and managed plant risk. The inspectors reviewed the scope of maintenance work, discussed the results of the assessment with the licensee's probabilistic risk analyst or shift technical advisor, and verified plant conditions were consistent with the risk assessment. The inspectors also reviewed the technical specification requirements and inspected portions of redundant safety systems, when applicable, to verify risk analysis assumptions were valid and applicable requirements were met. Specific documents reviewed during this inspection are listed in the attachment.
These activities constitute completion of five maintenance risk assessments and emergent work control inspection samples, as defined in Inspection Procedure 71111.13-05.
b. Findings
No findings were identified.
1R15 Operability Determinations and Functionality Assessments
a. Inspection Scope
The inspectors reviewed the following assessments:
- July 3, Main turbine control valve 3 and thermal limits
- August 5, Service water Division I and II discharge piping
- August 9, Diesel generator 2 driven lube oil pump
- September 4, 18 feet feedwater line break on the 903 feet level of the reactor building
- September 16, Residual heat removal pump B GE CR120AD relay The inspectors selected these operability and functionality assessments based on the risk significance of the associated components and systems along with other factors, such as engineering analysis and judgement, operating experience, and performance history. The inspectors evaluated the technical adequacy of the evaluations to ensure technical specification operability was properly justified and to verify 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 the Updated Final Safety Analysis Report to the licensees evaluations to determine whether the components or systems were operable. Where compensatory measures were required to maintain operability, the inspectors determined whether the measures in place would function as intended and were properly controlled. Additionally, the inspectors reviewed a sampling of corrective action documents to verify that the licensee was identifying and correcting any deficiencies associated with operability evaluations. Specific documents reviewed during this inspection are listed in the attachment.
These activities constitute completion of five operability evaluations inspection samples, as defined in Inspection Procedure 71111.15-05.
b. Findings
Introduction.
The inspectors identified a Green, non-cited violation of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, associated with the licensees failure to perform an adequate operability determination in accordance with Station Procedure 0.5OPS, Operations Review of Condition Reports/Operability Determination.
Description.
The inspectors selected Condition Reports CR-CNS-2013-04081 and CR-CNS-2013-06203 for review based on their risk significance and previously identified failure of a relay associated with residual heat removal pump B. The relay failure occurred after 42 hours4.861111e-4 days <br />0.0117 hours <br />6.944444e-5 weeks <br />1.5981e-5 months <br /> of operation on June 2, 2013. This failure prevented residual heat removal Division II minimum flow valve RHR-MOV-16B from opening automatically when residual heat removal pump B flow was lowered, and the reactor building southwest quad fan coil unit from starting and operating in conjunction with residual heat removal pump B. The licensee immediately declared residual heat removal pump B inoperable and replaced the relay on June 2, 2013. The licensee entered this issue in the stations corrective action program for resolution as Condition Report CR-CNS-2013-04081.
During their review of the apparent cause evaluation, documented in Condition Report CR-CNS-2013-04081, inspectors noted the following:
- (1) the identified apparent cause was a manufacturing defect present at the time of installation causing an infant mortality type failure, as documented in 10 CFR Part 21, Notification 97-62-0, Short circuit of coil of Type CR120AD relays, issued in June 1997;
- (2) the contributing cause was an inadequate qualification/testing process which failed to identify the manufacturing defect; and
- (3) from the extent of condition review the replacement relay installed on June 2, 2013, was part of the same equipment batch as the failed relay, and
- (4) the licensee concluded that the failure of the relay would not have an adverse effect on nuclear safety. The licensee initiated the following corrective actions:
- (1) add to the purchase requirements for CR120AD relays to go through a 100 hour0.00116 days <br />0.0278 hours <br />1.653439e-4 weeks <br />3.805e-5 months <br /> burn-in period and then cycle the relay 100 times to prevent infant mortality failures caused by undetected manufacturing detects; and
- (2) initiated Condition Report CR-CNS-2013-06203 to create a work order to replace the residual heat removal pump Bs relay installed on June 2, 2013, with a relay that has passed a 100 hour0.00116 days <br />0.0278 hours <br />1.653439e-4 weeks <br />3.805e-5 months <br /> burn-in period with 100 cycles at the next available opportunity.
Inspectors reviewed Condition Report CR-CNS-2013-06203 and its documented operability evaluation. During this review they noted that the licensee concluded that this condition report does not identify an equipment deficiency and that residual heat removal pump B remains operable. Specifically, the evaluation stated this is a work order request to replace the relay with one that has undergone a burn-in and cycle test to ensure it has operated beyond a period of infant mortality and that the relay installed on June 2, 2013, would not have an adverse effect on nuclear safety.
The licensee had only evaluated operability associated with the reactor building southwest quad fan coil unit and did not assess operability associated with RHR-MOV-16B. Specifically, the licensee failed to consider that failure of this relay could have prevented residual heat removal Division II minimum flow valve RHR-MOV-16B from opening automatically when residual heat removal pump B flow was lowered.
Therefore, the licensee had concluded that a failure of the replacement relay would not have an adverse effect on nuclear safety.
Inspectors questioned the licensees operability determination. Specifically, if the currently installed relay was part of the same equipment batch as the failed relay, and the failure was caused by a manufacturing defect, why there was assurance that the same condition was not present in the installed relay. Based on this, inspectors determined the licensees operability evaluation was not adequate to fully establish the pumps operability. Inspectors informed the licensee of their concerns. To capture this concern, in the stations corrective action program, the licensee initiated Condition Report CR-CNS-2013-06455.
As an immediate action, the licensee completed an operability evaluation that considered the relays hours of operation and burn-in requirement. The licensee determined residual heat removal pump B had been started eleven times with a combined run time of approximately 83 hours9.606481e-4 days <br />0.0231 hours <br />1.372354e-4 weeks <br />3.15815e-5 months <br /> with no discrepancies noted. From the 83 hours9.606481e-4 days <br />0.0231 hours <br />1.372354e-4 weeks <br />3.15815e-5 months <br /> of successful run time with no indication of failures and no vendor recommended requirement to perform a burn-in, the licensee concluded the residual heat removal pump B, and its associated auxiliary functions, remained operable.
The inspectors determined that the apparent cause of this finding was that the licensee had failed to use conservative assumptions and failed to adopt a requirement to demonstrate that the proposed action was safe in order to proceed, rather than a requirement to demonstrate that it was unsafe in order to disapprove the action. The licensee had failed to validate that the failure of the relay installed on June 2, 2013, would have no adverse effect on nuclear safety and considered it acceptable to replace the relay at the next available opportunity as documented in the apparent cause evaluation extent of condition and Condition Report CR-CNS-2013-06203.
Analysis.
The failure to properly assess and document the basis for operability when a degraded or nonconforming condition was identified was a performance deficiency. The performance deficiency was more than minor, and therefore a finding, because it was associated with the equipment performance attribute of the Mitigating Systems Cornerstone and affected the cornerstone objective. Specifically, the licensees failure to properly document and assess the basis for operability resulted in a condition of unknown operability for a degraded nonconforming system, thereby affecting the associated objective to ensure availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. The inspectors evaluated the finding using Inspection Manual Chapter 0609, Appendix A, The Significance Determination Process (SDP) For Findings At-Power, and determined that the finding was of very low safety significance (Green) because the finding:
- (1) was not a deficiency affecting the design and qualification of a mitigating structure, system, or component, and did not result in a loss of operability or functionality;
- (2) did not represent a loss of system and/or function;
- (3) did not represent an actual loss of function of at least a single train for longer than its technical specification allowed outage time, or two separate safety systems out-of-service for longer than their technical specification allowed outage time; and
- (4) did not represent an actual loss of function of one or more nontechnical specification trains of equipment designated as high safety-significance in accordance with the licensees maintenance rule program. The finding has a cross-cutting aspect in the area of human performance associated with the decision-making component because the licensee did not adopt a requirement to demonstrate that the proposed action was safe in order to proceed, rather than a requirement to demonstrate that it was unsafe in order to disapprove the action H.1(b).
Enforcement.
Title 10 CFR Part 50, Appendix B, Criterion V requires, in part, that activities affecting quality shall be accomplished in accordance with documented instructions, procedures, or drawings, of a type appropriate to the circumstances.
Station Procedure 0.5OPS, Operations Review of Condition Reports/Operability Determination, a procedure that is appropriate to the circumstances of evaluating the operability of safety-related components, required the licensee to properly assess and document the basis for operability when a degraded or nonconforming condition was identified. Contrary to the above, an activity affecting quality was not accomplished in accordance with a procedure that was appropriate to the circumstances. Specifically, on August 30, 2013, when the licensee evaluated the operability of residual heat removal pump B for infant mortality issues from manufacturing defects with relays, the licensee did not properly assess and document the basis for operability. This violation is being treated as a non-cited violation, consistent with Section 2.3.2.a of the Enforcement Policy. The violation was entered into the licensee correction action program as Condition Report CR-CNS-2013-06455. (NCV 05000298/2013004-03, Failure to Follow Operability Procedure)

The specific documents reviewed during this inspection are listed in the attachment.
These activities constitute completion of one maintenance of emergency preparedness sample, as defined in Inspection Procedure 71114.05-06.
b. Findings
Introduction.
The inspectors identified a Green non-cited violation for the licensees failure to implement an alternate staging area for emergency response organization staff normally assigned to onsite emergency response facilities, accessible when the site is under threat of, or experiencing, hostile action, as required by Appendix E to 10 CFR Part 50, IV.E(8)(d).
Description.
The NRC identified that the licensee failed to implement an alternate staging area accessible when the site is under threat of or experiencing hostile action.
Specifically, the licensees implementation of an alternate staging area for emergency response organization staff normally assigned to onsite emergency response facilities at the Auburn, Nebraska, Offsite Response Facility would have conflicted with the response of the licensees Joint Information Center.
The Cooper Nuclear Stations Auburn, Nebraska, Offsite Response Facility normally houses the licensees Emergency Operations Facility and Joint Information Center. The inspector reviewed the licensees plans for locating an alternative staging area at the Offsite Response Facility for emergency response organization personnel normally assigned to onsite emergency response facilities. The inspector determined the licensee had means to inform all emergency response organization staff to report to the Offsite Response Facility as needed, and had appropriately trained staff about how they would be notified to report to the alternate location. However, the licensee had not described the alternate staging area in Emergency Plan, Revision 63, or prepared procedures or other guidance for implementing the staging area.
The inspector visited the Offsite Response Facility on June 27, 2013, to determine whether licensee plans could be effectively implemented. Licensee representatives described that relocated Technical Support Center staff would be placed in working rooms in the Joint Information Center, and relocated Operations Support Center staff would be placed in the building lobby and adjacent press work room. The licensee stated that Technical Support Center staff would occupy some work stations normally assigned to Joint Information Center staff, potentially displacing or reducing existing staff.
The inspector determined that:
- The licensee had not identified specific locations for Technical Support Center staff and had not evaluated how the Technical Support Center and Joint Information Center staff would function in a co-located space;
- Implementation of the alternate staging area could displace Joint Information Center staff required by the site emergency plan;
- Use of the building lobby and press work room would affect access to the Joint Information Center auditorium;
- The licensee had not trained Joint Information Center, Technical Support Center, or Operations Support staff in implementing the staging area; and
- The licensee had not identified how to provide news organization access to the Joint Information Center auditorium when the building was used as an alternate facility, or how to provide appropriate facility access control or security.
Based on the above, the inspector concluded that implementing an alternate staging area for the relocated onsite emergency response organization at the Auburn, Nebraska, Offsite Response Facility would conflict with functions of the Joint Information Center.
Analysis.
The inspector determined that failure to provide a facility accessible when the site is under threat of or experiencing hostile action is a performance deficiency within the licensees ability to foresee and correct. This finding is more than minor because it affected the facilities and equipment emergency preparedness cornerstone attribute (maintenance, surveillance, and testing of facilities). The finding had a credible impact on the cornerstone objective because the licensees ability to implement adequate measures to protect the health and safety of the public during a radiological emergency would be affected if it could not stage personnel to respond to the site during events involving hostile action, or in other events in which access to the site is impeded. The ability to communicate measures to protect the health and safety of the public would also be affected if there were impediments to Joint Information Center operations. The finding was associated with a violation of NRC requirements. This finding was evaluated using IMC 0609, Appendix B, Emergency Preparedness Significance Determination Process and was determined to be of very low safety significance (Green) because it was a failure to comply with NRC requirements and was not a loss of planning standard function. The planning standard was not lost because the finding affected an alternate facility and the impediments would not have precluded the Joint Information Center from fulfilling its emergency functions. This finding was assigned a cross-cutting aspect in the area of Human Performance associated with the resources component because the licensee did not provide and maintain adequate emergency facilities, and the finding is reflective of current performance H.2(d).
Enforcement.
Title 10 CFR 50.54(q)(2) states, in part, a holder of a licenseshall follow and maintain the effectiveness of an emergency plan that meets the requirements in Appendix E, and for nuclear power reactor licensees, the planning standards of 50.47(b). Planning standard 50.47(b)(8) requires that adequate emergency facilities to support the emergency response are provided and maintained. Appendix E to Part 50, Part IV.E(8)(d), requires a licensee to have by June 20, 2012, a facility that would be accessible even if the site is under threat of or experiencing hostile action to function as a staging area for augmentation. The Cooper Nuclear Station Emergency Plan, Revision 63, Section 7.2.4, requires a Joint Information Center. Contrary to the above, between June 20, 2012, and June 27, 2013, the Cooper Nuclear Station did not have a facility accessible even if the site is under threat of or experiencing hostile action.
Specifically, implementation of a staging area accessible when the site is under threat of or experiencing hostile action would have created impediments to the effective operation of the licensees Joint Information Center. Because this failure is of very low safety significance and has been entered into the licensees corrective action program CR-CNS-2013- 04765, this violation is being treated as an non-cited violation, consistent with Section 2.3.2a of the NRC Enforcement Policy: NCV 05000298/2013004-04, Failure to Provide a Staging Area for Augmented Emergency Response Personnel When the Site Is Not Accessible.
RADIATION SAFETY
Cornerstones: Public Radiation Safety and Occupational Radiation Safety
2RS1 Radiological Hazard Assessment and Exposure Controls
a. Inspection Scope
This area was inspected to:
- (1) review and assess the licensees performance in assessing the radiological hazards in the workplace associated with licensed activities and the implementation of appropriate radiation monitoring and exposure control measures for both individual and collective exposures;
- (2) verify the licensee is properly identifying and reporting Occupational Radiation Safety Cornerstone performance indicators; and
- (3) identify those performance deficiencies that were reportable as a performance indicator and which may have represented a substantial potential for overexposure of the worker.
The inspectors used the requirements in 10 CFR Part 20, the technical specifications, and the licensees procedures required by technical specifications as criteria for determining compliance. During the inspection, the inspectors interviewed the radiation protection manager, radiation protection supervisors, and radiation workers. The inspectors performed walkdowns of various portions of the plant, performed independent radiation dose rate measurements, and reviewed the following items:
- Performance indicator events and associated documentation reported by the licensee in the Occupational Radiation Safety Cornerstone
- The hazard assessment program, including a review of the licensees evaluations of changes in plant operations and radiological surveys to detect dose rates, airborne radioactivity, and surface contamination levels
- Instructions and notices to workers, including labeling or marking containers of radioactive material, radiation work permits, actions for electronic dosimeter alarms, and changes to radiological conditions
- Programs and processes for control of sealed sources and release of potentially contaminated material from the radiologically controlled area, including survey performance, instrument sensitivity, release criteria, procedural guidance, and sealed source accountability
- Radiological hazards control and work coverage, including the adequacy of surveys, radiation protection job coverage, and contamination controls; the use of electronic dosimeters in high noise areas; dosimetry placement; airborne radioactivity monitoring; controls for highly activated or contaminated materials (non-fuel) stored within spent fuel and other storage pools; and posting and physical controls for high radiation areas and very high radiation areas
- Radiation worker and radiation protection technician performance with respect to radiation protection work requirements
- Audits, self-assessments, and corrective action documents related to radiological hazard assessment and exposure controls since the last inspection Specific documents reviewed during this inspection are listed in the attachment.
These activities constitute completion of the one required sample as defined in Inspection Procedure 71124.01-05.
b. Findings
No findings were identified.
2RS2 Occupational ALARA Planning and Controls
a. Inspection Scope
This area was inspected to assess performance with respect to maintaining occupational individual and collective radiation exposures as low as is reasonably achievable (ALARA). The inspectors used the requirements in 10 CFR Part 20, the technical specifications, and the licensees procedures required by technical specifications as criteria for determining compliance. During the inspection, the inspectors interviewed licensee personnel and reviewed the following items:
- Site-specific ALARA procedures and collective exposure history, including the current 3-year rolling average, site-specific trends in collective exposures, and source-term measurements
- ALARA work activity evaluations/postjob reviews, exposure estimates, and exposure mitigation requirements
- The methodology for estimating work activity exposures, the intended dose outcome, the accuracy of dose rate and man-hour estimates, and intended versus actual work activity doses and the reasons for any inconsistencies
- Records detailing the historical trends and current status of tracked plant source terms and contingency plans for expected changes in the source term due to changes in plant fuel performance issues or changes in plant primary chemistry
- Radiation worker and radiation protection technician performance during work activities in radiation areas, airborne radioactivity areas, or high radiation areas
- Audits, self-assessments, and corrective action documents related to ALARA planning and controls since the last inspection Specific documents reviewed during this inspection are listed in the attachment.
These activities constitute completion of the one required sample as defined in Inspection Procedure 71124.02-05.

4OA2 Problem Identification and Resolution
.1 Routine Review of Identification and Resolution of Problems
a. Inspection Scope
As part of the various baseline inspection procedures discussed in previous sections of this report, the inspectors routinely reviewed issues during baseline inspection activities and plant status reviews to verify that they were being entered into the licensees corrective action program at an appropriate threshold, that adequate attention was being given to timely corrective actions, and that adverse trends were identified and addressed. The inspectors reviewed attributes that included the complete and accurate identification of the problem; the timely correction, commensurate with the safety significance; the evaluation and disposition of performance issues, generic implications, common causes, contributing factors, root causes, extent of condition reviews, and previous occurrences reviews; and the classification, prioritization, focus, and timeliness of corrective actions. Minor issues entered into the licensees corrective action program because of the inspectors observations are included in the attached list of documents reviewed.
These routine reviews for the identification and resolution of problems did not constitute any additional inspection samples. Instead, by procedure, they were considered an integral part of the inspections performed during the quarter and documented in Section 1 of this report.
b. Findings
No findings were identified.
.2 Daily Corrective Action Program Reviews
a. Inspection Scope
In order to assist with the identification of repetitive equipment failures and specific human performance issues for follow-up, the inspectors performed a daily screening of items entered into the licensees corrective action program. The inspectors accomplished this through review of the stations daily corrective action documents.
The inspectors performed these daily reviews as part of their daily plant status monitoring activities and, as such, did not constitute any separate inspection samples.
b. Findings
No findings were identified.
.3 Selected Issue Follow-up Inspection
a. Inspection Scope
During a review of items entered in the licensees corrective action program, the inspectors recognized a corrective action item documenting residual heat removal Division II residual heat removal pump B, minimum full valve RHR-MOV-16B, and reactor building southwest quad fan coil unit issues due to a relay failure.
During a review of items entered in the licensees corrective action program, the inspectors recognized a corrective action item dealing with residual heat removal system Division II. The inspectors considered the following, as applicable, during the review of the licensees actions:
- (1) complete and accurate identification of the problem in a timely manner;
- (2) evaluation and disposition of operability/reportability issues;
- (3) consideration of extent of condition, generic implications, common cause, and previous occurrences;
- (4) classification and prioritization of the resolution of the problem;
- (5) identification of apparent causes and contributing causes of the problem;
- (6) identification of corrective actions; and
- (7) completion of corrective action in a timely manner.
These activities constitute completion of one in-depth problem identification and resolution sample, as defined in Inspection Procedure 71152-05.

The inspectors noted that the actions implemented by the licensee involved testing of one diesel generator, and generation of an acceptable analysis demonstrating compliance for the other diesel generator. The inspectors determined that these actions have addressed the concerns expressed in the violation. This violation is closed.
4OA6 Meetings, Including Exit
Exit Meeting Summary
On June 28, 2013, the inspector presented the results of the onsite inspection of the licensees emergency preparedness program to Mr. K. Higginbotham, General Plant Manager, Operations, and other members of the licensees 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.
On August 8, 2013, the inspectors presented the results of the radiation safety inspections to Mr. D. Buman, Director, Engineering, and other members of the licensee staff. The licensee acknowledged the issues presented. The inspectors asked the licensee whether any materials examined during the inspection should be considered proprietary. One document was identified as proprietary by licensee personnel, so the document was returned to the licensee after the inspectors review.
On October 7, 2013, the inspectors presented the inspection results to Mr. O. Limpias, Vice President-Nuclear and Chief Nuclear Officer, 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.
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 meets the criteria of the NRC Enforcement Policy for being dispositioned as a non-cited violation.
Emergency Response Organization Position not Staffed Title 10 CFR 50.54(q)(2), requires that a power reactor licensee follow an emergency plan that meets the requirements of 10 CFR 50.47(b) and Appendix E to Part 50.
Title 10 CFR 50.47(b)(1), requires that a licensee have staff to augment its initial emergency response. Section 5.3.1 of the Cooper Nuclear Station Emergency Plan, Revision 63, requires Joint Information Center management to be supported by the Joint Information Center Facility Manager. Contrary to the above, between approximately May 1 and July 10, 2012, the Cooper Nuclear Station did not follow an emergency plan that met the requirements of 10 CFR 50.47(b) and Appendix E to Part 50. Specifically, it did not follow emergency plan Section 5.3.1 of the Cooper Nuclear Station Emergency Plan because there were no qualified staff assigned to the position of Joint Information Center Facility Manager. This finding was more than minor because it affected the emergency response organization readiness cornerstone attribute (duty roster). The finding was evaluated by the Emergency Preparedness Significance Determination Process and determined to be of very low safety significance (Green) because it was a failure to comply with NRC requirements, and was not a loss of planning standard function. The planning standard function was not lost because the Joint Information Center would have been able to perform its emergency function without a Joint Information Center Facility Manager, although in a degraded manner. This finding was entered into the licensees corrective action program as Condition Report CR-CNS-2012-04492.
