|
| The inspection identified two apparent violations (AV), two Green noncited violations (NCV) and two unresolved items (URI). The significance of most findings is indicated by their color (Green, White, Yellow, Red) using IMC 0609 "Significance Determination Process" (SDP).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 described its program for overseeing the safe operation of commercial nuclear power reactors in NUREG-1649, "Reactor Oversight Process," Revision 3, dated July 2000.A.

| Mitigating Systems* Green. The team identified a noncited violation (NCV) for failure to comply with Technical Specification (TS) 5.4, "Procedures", in that a procedure required for post-fire safe shutdown was found to be inadequat Procedure OFN RP-014, "Hot Standby to Cold Shutdown from Outside the Control Room", was inadequate because it did not provide a method to provide sufficiently borated water to the reactor coolant system so that cold shutdown could be achieved and maintained within 72 hours after a control room fire. Procedure OFN RP-014 requires monitoring of the boron concentration in the reactor and, if necessary, starting the acid transfer pumps to draw borated Water from the boric acid tanks. However, this procedure did not include sufficient instructions for refilling and borating the Refueling Water Storage Tank for a potential loss of offsite power or fire inducted damage to circuits related to the pumps.This finding is greater than minor because it impacted the mitigating systems cornerstone objective to ensure the availability, reliability, and capability of systems that respond to external events (such as fire) to prevent undesirable consequences (i.e., core damage). The inspectors evaluated the finding using MC 0609, Appendix F, and determined that it screens as very low safety significance (Green) because it is related to the ability to achieve and maintain cold shutdown. (Section 1 R05.1.b.(1))

| * TBD. The team identified an Apparent Violation (AV) of Wolf Creek License Condition 2.C. (5) (a) concerning an inadequate alternate shutdown analysi The licensee's alternate shutdown analysis was inadequate in that it used acceptance criteria which were inconsistent with and less conservative than those required by the approved Fire Protection Program. The licensee developed Calculation Number AN-02-021, Revision 0, "OFN RP-017 "Control Room Evacuation" Consequence Evaluation", to demonstrate alternative shutdown capability for W01olf Creek in response to NRC identified noncited violation 200208-01, Inadequate alternative shutdown procedur The licensee used no fuel damage as an acceptance criteri The calculation predicted that during an alternative shutdown, the reactor coolant system subcooling margin would not maintained, significant voiding would occur in the core, and a steam void would form in Intorinatio:n in this record was; deleted Enclosure in accordance with the Freedom of Information At, exemptions

| ' G EOIA- `'--0 2S-2-the reactor vessel head. The licensee found the results of the calculation to be acceptable since it demonstrated that the void formation would be limited, natural circulation in the reactor coolant system would be maintained, sufficient decay heat removal would be maintained, and no fuel damage would occur. This is not consistent with the license condition to meet the technical requirements of 10 CFR Part 50, Appendix R. Section II.L of 10 CFR Part 50 Appendix R, "Alternative and dedicated shutdown capability", states in part, "During the postfire shutdown, the reactor process variables shall be maintained within those predicted for a loss of normal a.c. power".This finding is greater than minor because it impacted the mitigating systems cornerstone objective to ensure the availability, reliability, and capability of systems that respond to external events (such as fire) to prevent undesirable consequences (i.e., core damage). The licensee considers the spurious operation of multiple components to be outside of the plant licensing basis for the Fire Protection Program. Specifically, in this case, both pressurizer power-operated relief valves are assumed to spuriously open due to fire induced circuit damage. It is the NRC's understanding that the licensee does not consider these circuit vulnerabilities to be violations of NRC requirement The NRC staff and the industry are currently working on developing a resolution methodology to address these types of potential fire-inducted circuit failure The team concluded that this violation meets the criteria of the NRC Enforcement Manual Section 8.1.7.1 for deferring enforcement actions for postulated fire induced circuit failures. (Section 1 R05.1 .b.(2))Green. The team identified a noncited violation of License Condition 2.C.(5), Fire Protection (Section 9.5.1, SER, Section 9.5.1.8, SSER #5), for failure to ensure that redundant trains of safe shutdown systems in the same fire area were free of fire damage. The licensee credited manual actions to mitigate the effects of fire damage in lieu of providing the physical protection required by 10 CFR Part 50, Appendix R, Section III.G.2.SNUPPS FSAR Appendix 9.5E provided the design comparison between the plant's fire protection program and 10 CFR 50, Appendix R. The comparison to Section III.G, Fire Protection of Safe Shutdown Capability, states, "Redundant trains of systems required to achieve and maintain hot standby are separated by 3-hour-rated fire barriers, or the equivalent provided by III.G.2, or else a diverse means of providing the safe shutdown capabilitv exists that is unaffected by the fire." Wolf Creek has interpreted "diverse means" to mean by any reasonable means including local valve and breaker operations as long as they are within the scope of normal operator duties. The team disagrees with this interpretatio The NRC staff does not recognize the use of manual actions as meeting the technical requirements of Appendix R, Section III.G.2. The components being operated are identified as required for operation of safe shutdown systems or are subject to potential spurious operation impacting the shutdow The local manual actions are being performed due to fire damage to electrical cables related to those components and are meant to compensate for damage or maloperation of safe shutdown equipment caused by fire.Enclosure-3-This finding is greater than minor because it impacted the mitigating systems cornerstone objective to ensure the availability, reliability, and capability of systems that respond to external events (such as fire) to prevent undesirable consequences (i.e., core damage). The team found that the manual operator actions implemented to mitigate the effects of fire damage were reasonable (as defined in Enclosure 2 of NRC Inspection Procedure 71111 .05T, "Fire Protection (Triennial)"), and could be performed within the analyzed time limits. Therefore, in accordance with Enclosure 2 of NRC Inspection Procedure 71111 .05T, the finding was determined to be of very low safety significance (green), and the significance determination process was not entered.(Section 1 R05.2)TBD. The team identified an Apparent Violation (AV) of Technical Specification 5.4, Procedures, clue to an inadequate alternate shutdown procedure which is required fo implementation of the Fire Protection Program. The team found that some time critical actions required to safely shutdown the plant following a control room fire could not be accomplished within the requied time periods. Specifically, the licensee's procedure meets the recommendations by Westinghouse Owners Group for assuring RCP seal reliability and avoiding component cooling water thermal barrier water hammer concerns based on a time line assuming operators only have to respond to one spurious operation from the fire-induced damage during the scenari The team disagrees which this limitation of potential spurious operations.

| B. Licensee-identified Violations None Enclosure I S-6-.2 Protection of Safe Shutdown Capabilities a. Inspection Scope The team reviewed the licensee's piping and instrumentation diagrams, safe shutdown equipment list, safe shutdown design basis documents, and the post-fire safe shutdown analysis to verify whether the licensee's shutdown methodology had properly identified the components and systems necessary to achieve and maintain safe shutdown conditions for equipment in the fire areas selected for review. The team also reviewed and observed walkdowns of the licensee's procedures for achieving and maintaining safe shutdown in the event of a fire to verify that the safe shutdown analysis provisions were properly implemente The team focused on the following functions that must be ensured to achieve and maintain post-fire safe shutdown conditions:

|
| The team reviewed the separation of safe shutdown cables, equipment, and components within the same fire areas, and reviewed the licensee's methodology for meeting the requirements of 10 CFR 50.48, Appendix A to Branch Technical Position 9.5-1 and 10 CFR Part 50, Appendix R, Section III.G. Specifically, this was to determine whether at least one post-fire safe shutdown success path was free of fire damage in the event of a fire in the selected areas. The evaluation focused on the cabling of selected components for the chemical and volume control system, high pressure safely injection system, and the auxiliary feedwater system. A sample of components was selected whose inadvertent operation could significantly affect the shutdown capability credited in the licensee's safe shutdown analysi The specific components selected are listed in the attachmen In addition, the team reviewed license documentation, such as NRC safety evaluation reports, the Wolf Creek Updated Final Safety Analysis Report, submittals made to the NRC by the licensee in support of the NRC's review of their fire protection program, and deviations from NRC regulations to verify that the licensee met license commitments.

| The team identified a noncited violation of License Condition 2.C.(5), Fire Protection (Section 9.5.1, SER, Section 9.5.1.8, SSER #5), for failure to ensure that redundant trains of safe shutdown systems in the same fire area were free of fire damage. The licensee credited manual actions to mitigate the effects of fire damage in lieu of providing the physical protection required by 10 CFR Part 50, Appendix R, Section III.G.2. The team determined that the violation was of very low safety significance (green).Enclosure-7-Descriptio Wolf Creek License Condition 2.C. (5) (a) states "The Operating Corporation shall maintain in effect all provisions of the approved fire protection program as described in the SNUPPS Final Safety Analysis Report for the facility through Revision 17, the Wolf Creek site addendum through Revision 15, and as approved in the SER through Supplement 5, subject to provisions b & c below." SER Section 9.5.1.7, Appendix R Statement, states "The staff will condition the operating license to require the applicant to meet the technical requirements fo Appendix R to 10 CFR 50, or provide equivalent protection." Section III.G.2 of 10 CFR 50, Appendix R, describes three acceptable methods for protecting at least one safe shutdown train when redundant trains are located in the same fire area. The Section III.G.2 requirements are based on the combination of physical barriers, spacial separation, fire detection and automatic suppression systems.SNUPPS FSAR Appendix 9.5E provided the design comparison between the plant's fire protection program and 10 CFR 50, Appendix R. The comparison to Section III.G, Fire Protection of Safe Shutdown Capability, states, "Redundant trains of systems required to achieve and maintain hot standby are separated by 3-hour-rated fire barriers, or the equivalent provided by III.G.2, or else a diverse means of providing the safe shutdown capability exists that is unaffected be the fire." Wolf Creek has interpreted "diverse means" to mean by any reasonable means including local valve and breaker operations as long as they are within the scope of normal operator duties. The team disagrees with this interpretatio The NRC staff does not recognize the use of manual actions as meeting the technical requirements of Appendix R. The components being operated are identified as required for operation of safe shutdown systems or are subject to potential spurious operation impacting the shutdow The local manual actions are being performed due to fire damage to electrical cables related to those components and are meant to compensate for damage or maloperation of safe shutdown equipment caused by fire. Manual actions are not a method of satisfying Appendix R, Section III.G.2 requirement Plant specific manual actions may be acceptable based on detailed specific exemptions or deviations for each case identified.

| Analysi This finding is of greater than minor safety significance because it impacted the mitigating systems cornerstone objective to ensure the availability, reliability, and capability of systems that respond to external events (such as fire) to prevent undesirable consequence The team reviewed Procedure OFN KC-016, "Fire Response" and stepped through the manual actions directed in the procedure with licensee operations personne The team found that the manual operator actions were reasonable (as defined in Enclosure 2 of Inspection Procedure 71111 .05T), and could be performed within the analyzed time limits. Since the manual operator actions was considered reasonable, the significance determination process was not entered. The team determined that this finding is of very low safety significance (green) in accordance with the guidance in Enclosure 2 to Inspection Procedure 71111 .05T.Enforcemen The licensee's Fire Hazard Analysis states that it will comply with the technical requirements of Appendix R or utilize a diverse means to do so. Appendix R, Section III.G.2 to 10 CFR Part 50 requires that cables whose fire damage could prevent the operation or cause maloperation of safe shutdown functions be physically protected Enclosure-8-from fire damage. Contrary to this requirement, the licensee implemented a methodology that utilized manual operator actions as a diverse means to mitigate the effects of fire damage in lieu of providing physical protection from fire damage. This is a violation of Wolf Creek License Condition 2.C. (5) (a) for failing to meet the technical requirements of 10 CFR 50, Appendix R, as required by SER Section 9.5.1.7. Because this finding is of very low safety significance, this violation is being treated as a noncited violation, consistent with Section VL.A of the NRC Enforcement Policy: NCV 05000482/2005008-03, Failure to Ensure Redundant Safe Shutdown Systems Located In the Same F:ire Area Are Free of Fire Damage..3 Passive Fire Protection a. Inspection Scope For the selected fire areas, the team evaluated the adequacy of fire area barriers, penetration seals, fire doors, electrical raceway fire barriers and fire rated electrical cables. The team observed the material condition and configuration of the installed barriers, seals, doors, and cables. The team compared the as-installed configurations to the approved construction details and supporting fire tests. In addition, the team reviewed license documentation, such as NRC safety evaluation reports, and deviations from NRC regulations and the National Fire Protection Association code to verify that fire protection features met license commitments.

| The team also observed an announced site fire brigade drill and the subsequent drill critique using the guidance in Inspection Procedure 71111.05A Team members observed the fire brigade simulate fire fighting activities in plant Fire Area T-4 (Lube Oil Storage Room). 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 fire fighting equipment Enclosure c ITEMS OPENED AND CLOSED Opened 05000482/2005008-02 05000482/2005008-04 05000482/2005008-05 05000482/2005008-06 AV Failure to Maintain Reactor Coolant System Subcooling During the Alternate Shutdown (1 R05.1.b(2)) | | The inspectors completed one sample. |

| | b.FindingsFailure to Follow the Clearance Order ProcedureIntroduction: An apparent violation (AV) of Technical Specification 5.4.1a occurredwhen station personnel failed to follow Procedure AP 21E-001, "Clearance Orders," and manipulated a component inside a fire protection piping clearance boundary without instructions and authorization. The starting of a temporary fire pump resulted in water-14-Enclosurespraying on the controller of the operable diesel-driven fire pump through an open ventvalve, which rendered the pump inoperable.Description: On June 30, 2005, the motor of the electric fire pump experienced a shortin its winding which led to a fire at the motor. The plant took the appropriate compensatory measures and started parallel paths to restore the fire suppression water system within the allotted 14 days. One path involved a temporary modification to thefire protection system that installed a temporary motor-driven fire pump, which was accomplished on July 11, 2005. The temporary fire pump was tested on July 12, 2005, to verify it would provide the required flow of water suppression; however, the pump failed this test. Station fire protection personnel requested a clearance order to isolate the temporaryfire pump from the fire protection piping but failed to make station operations personnel aware of the desire to run the temporary fire pump following repairs. Once repairs to the pump were completed, the vendor under the direction of station fire protectionpersonnel started the pump believing they had authorization to operate the temporaryfire pump. This resulted in water issuing from an open vent valve which sprayed the controller of the diesel-driven fire pump. Station fire protection personnel discovered the wet controller and notified the control room. Control room personnel declared the diesel-driven fire pump inoperable. The diesel-driven fire pump was returned to service in approximately 4 hours. The inspectors reviewed Procedure AP-10-103, Fire Protection Impairment Control, Revision 19, which identified the compensatory measures for the loss of fire suppression water systems. With the motor driven and the diesel driven fire pumpinoperable (approximately 4 hours) the impairment control procedure required that abackup fire pump be provided within 24 hours. In this case, both the motor driven and the diesel driven fire pumps were restored within approximately 18 hours. This issue involved human performance crosscutting aspects associated with station personnel notfollowing a station procedure.Analysis: The failure to follow station procedures is a performance deficiency. Thefinding was determined to be more than minor because it affected the mitigating systems cornerstone objective of ensuring the availability, reliability, and capability ofsystems that respond to initiating events to prevent undesirable consequences.

| | the finding was determined to degrade the fire protecti on system suppression and wasevaluated using Appendix F, Fire Protection Significance Determination Process. This finding requires a Phase 3 analysis and is currently under evaluation. Wolf Creek Nuclear Operating Corporation entered this finding into their corrective action program as PIR 2005-2142 Enforcement: Technical Specification 5.4.1a requires procedures be implemented inaccordance with Regulatory Guide 1.33, Revision 2, Appendix A. RegulatoryGuide 1.33, Appendix A, Section 9, requires procedures for the performance of stationmaintenance. Contrary to the above, on July 13, 2005, station personnel operated-15-Enclosurecomponents inside an established fire protection piping clearance boundary withoutwork instructions or control room authorization as required by Station Procedure AP 21E-001, "Clearance Orders," Section 6.6.8. This resulted in an adjacent diesel-driven fire pump becoming inoperable. Pending determination of the final safety significance of this issue, this violation is being treated as an AV consistent with Section VI.A of the NRC Enforcement Policy: AV 05000482/0500404, manipulation ofplant component without proper authorization results in inoperable fire protection pumps.Corrective Action EffectivenessThere were no findings identified that were associated with the corrective actions for thisevent. However, the inspectors made the following observations from their review of the apparent cause evaluation and the associated corrective actions: The apparent cause evaluation states that some fire protection personnel are unfamiliar with the clearanceorder program because, for them, clearance orders are infrequently performed evolutions. Additionally, the evaluation states that some "groups" mistakenly believed itwas acceptable to work on vendor equipment inside clearance order boundaries without proper authorization or an approved procedure. These evaluation results suggest a clearance order program knowledge deficiency within the fire protection group. Yet, the corrective action for these contributing causes was counseling only the one individual involved with this event. .2Cross-References to Problem Identification & Resolution Findings DocumentedElsewhereSection 1R15 documents a condition where station personnel did not properly evaluatea condition adverse to quality regarding debris in the auxiliary feedwater flowtransmitters..3Access Control to Radiologically Significant Areas and ALARA InspectionsSection 2OS1 evaluated the effectiveness of WCNOC's problem identification andresolution processes regarding access controls to radiologically significant areas and radiation worker practices.

4.OTHER ACTIVITIES4OA2Identification and Resolution of ProblemsResident Inspector Annual Sample Review a.Inspection ScopeThe inspectors evaluated the effectiveness of WCNOC's corrective action program asapplied to corrective action document PIR 2005-2142. This document was initiated to address the conditions and events that led to the inoperability of both site fire protectionpumps. Attributes considered during this review included the following: *Completeness, accuracy, and timeliness of problem identification *Operability and reportability evaluation *Extent of condition evaluation
- Apparent cause evaluation
- Corrective action effectiveness
The inspectors completed one sample.
b.FindingsFailure to Follow the Clearance Order ProcedureIntroduction: An apparent violation (AV) of Technical Specification 5.4.1a occurredwhen station personnel failed to follow Procedure AP 21E-001, "Clearance Orders," and manipulated a component inside a fire protection piping clearance boundary without instructions and authorization. The starting of a temporary fire pump resulted in water-14-Enclosurespraying on the controller of the operable diesel-driven fire pump through an open ventvalve, which rendered the pump inoperable.Description: On June 30, 2005, the motor of the electric fire pump experienced a shortin its winding which led to a fire at the motor. The plant took the appropriate compensatory measures and started parallel paths to restore the fire suppression water system within the allotted 14 days. One path involved a temporary modification to thefire protection system that installed a temporary motor-driven fire pump, which was accomplished on July 11, 2005. The temporary fire pump was tested on July 12, 2005, to verify it would provide the required flow of water suppression; however, the pump failed this test. Station fire protection personnel requested a clearance order to isolate the temporaryfire pump from the fire protection piping but failed to make station operations personnel aware of the desire to run the temporary fire pump following repairs. Once repairs to the pump were completed, the vendor under the direction of station fire protectionpersonnel started the pump believing they had authorization to operate the temporaryfire pump. This resulted in water issuing from an open vent valve which sprayed the controller of the diesel-driven fire pump. Station fire protection personnel discovered the wet controller and notified the control room. Control room personnel declared the diesel-driven fire pump inoperable. The diesel-driven fire pump was returned to service in approximately 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />. The inspectors reviewed Procedure AP-10-103, Fire Protection Impairment Control, Revision 19, which identified the compensatory measures for the loss of fire suppression water systems. With the motor driven and the diesel driven fire pumpinoperable (approximately 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />) the impairment control procedure required that abackup fire pump be provided within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. In this case, both the motor driven and the diesel driven fire pumps were restored within approximately 18 hours2.083333e-4 days <br />0.005 hours <br />2.97619e-5 weeks <br />6.849e-6 months <br />. This issue involved human performance crosscutting aspects associated with station personnel notfollowing a station procedure.Analysis: The failure to follow station procedures is a performance deficiency. Thefinding was determined to be more than minor because it affected the mitigating systems cornerstone objective of ensuring the availability, reliability, and capability ofsystems that respond to initiating events to prevent undesirable consequences. Usingthe Phase 1 worksheets in Manual Chapter 0609, "Significance Determination Process,"
the finding was determined to degrade the fire protecti on system suppression and wasevaluated using Appendix F, Fire Protection Significance Determination Process. This finding requires a Phase 3 analysis and is currently under evaluation. Wolf Creek Nuclear Operating Corporation entered this finding into their corrective action program as PIR 2005-2142 Enforcement: Technical Specification 5.4.1a requires procedures be implemented inaccordance with Regulatory Guide 1.33, Revision 2, Appendix A. RegulatoryGuide 1.33, Appendix A, Section 9, requires procedures for the performance of stationmaintenance. Contrary to the above, on July 13, 2005, station personnel operated-15-Enclosurecomponents inside an established fire protection piping clearance boundary withoutwork instructions or control room authorization as required by Station Procedure AP 21E-001, "Clearance Orders," Section 6.6.8. This resulted in an adjacent diesel-driven fire pump becoming inoperable. Pending determination of the final safety significance of this issue, this violation is being treated as an AV consistent with Section VI.A of the NRC Enforcement Policy: AV 05000482/0500404, manipulation ofplant component without proper authorization results in inoperable fire protection pumps.Corrective Action EffectivenessThere were no findings identified that were associated with the corrective actions for thisevent. However, the inspectors made the following observations from their review of the apparent cause evaluation and the associated corrective actions: The apparent cause evaluation states that some fire protection personnel are unfamiliar with the clearanceorder program because, for them, clearance orders are infrequently performed evolutions. Additionally, the evaluation states that some "groups" mistakenly believed itwas acceptable to work on vendor equipment inside clearance order boundaries without proper authorization or an approved procedure. These evaluation results suggest a clearance order program knowledge deficiency within the fire protection group. Yet, the corrective action for these contributing causes was counseling only the one individual involved with this event. .2Cross-References to Problem Identification & Resolution Findings DocumentedElsewhereSection 1R15 documents a condition where station personnel did not properly evaluatea condition adverse to quality regarding debris in the auxiliary feedwater flowtransmitters..3Access Control to Radiologically Significant Areas and ALARA InspectionsSection 2OS1 evaluated the effectiveness of WCNOC's problem identification andresolution processes regarding access controls to radiologically significant areas and radiation worker practices. The inspectors reviewed corrective action documents for root cause/apparent cause analysis against WCNOC's PI&R process. No findings of significance were identified.Section 2OS2 evaluated the effectiveness of WCNOC's PI&R processes regardingexposure tracking, higher than planned exposure levels, and radiation worker practices.
The inspector reviewed the corrective action documents listed in the attachment against WCNOC's PI&R program requirements. No findings of significance were identified.
