Uynam1c Web S ite yes to the following question: Does the finding pertain to operations, and event, or a degraded condition while the plant was shut down? As a result, the inspectors were directed to use IMC 0609 Appendix G, Shutdown Operations Significance Determination Process. Using Appendix G the inspectors determined that the finding did need a quantitative assessment because the finding degrades the licensee s ability to recover decay heat removal once it is lost. As a result, the fmding was forwarded to a Senior Reactor Analyst for further quantitative analysis.

The finding represented a potential loss of the intake structure due to flooding, therefore, a Phase 3 evaluation by a senior reactor analyst was necessary. The senior reactor analyst evaluated a bounding risk analysis case which assumed that the raw water system and offsite power were lost. This bounding case had an incremental conditional core damage probability of 5.0 x 10-7, and therefore the finding was determined to have very low safety significance (Green). The inspectors determined the Green finding had a cross-cutting aspect in the area of problem identification and resolution because the licensee did not take appropriate corrective action to address safety issues and adverse trends in a timely manner, commensurate with their safety significance and complexity [P.l(d)].

Open: ML13 I44A772 (PIM) Inadequate functionality evaluation of the raw water pump anchor bolts The inspection team identified a finding of very low safety sigruficance involving the licensee s failure to meet the requirements of the American Concrete lnstitute (ACI) 349-0 l. Specifically, the licensee s past functionality calculation failed to ensure the raw water pump anchorage met ACI. 349-01 requirements. This finding was entered into the licensee s corrective action program. No violation ofNRC requirements was identified. The performance deficiency was detennincd to be more than minor because it was associated with the design control attribute of the Mitigating Systems Cornerstone and adversely affected the cornerstone objective of ensuring the reliability, availability, and capability of systems that respond to initiating events to prevent undesirable consequences. The finding screened as very low safety significance (Green) because the finding did not ultimately affect the operability or functionality of the anchorage. This finding had a cross-cutting aspect in the Decision-Making component of the Human Perfonnance cross-cutting area because the licensee used non-conservative assumptions in a functionality evaluation of raw water pump anchorage. Specifically, the licensee failed to use strength reduction factors as required by ACI 349-01 in the evaluation ofraw water pump anchorage [H.l(b)].

Open: ML I3 I92A50 L (PIM) Failure to Perform Extent of Condition Evaluation The inspectors identified a finding for the licensee s failure to follow their corrective action program procedures and perfonn an extent of condition evaluation. Specifically, the licensee failed to perform an extent of condition evaluation on emergency operating and abnormal operating procedures as required by procedure FCSG-24-5, "Cause Evaluation Manual" to identify other procedural deficiencies similar to those identified in non-cited violations NCV 05000285/2012301-0l, NCV 05000285/2012301-04, and NCV 05000285/2012301-06. The licensee's failure to perform an extent of condition review in accordance with FCSG-24-5 was a performance deficiency. The finding is more than minor because the failure to adequately implement corrective actions associated with identified procedural deficiencies affects the procedural quality attribute of the Mitigating Systems Cornerstone and affects the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Using the Mitigating Systems Screening Questions in Manual Chapter 0609, Appeodjx A, Exhibit 2, the finding is not a deficiency that resulted in a loss of operability or functionality of a safety significant component. Therefore, the finding is of very low safety significance. The finding has a cross-cutting aspect in the area of the problem identification and resolution associated with the corrective action program because the licensee failed to take appropriate corrective actions to address safety issues and adverse trends in a timely manner, commensurate with their safety significance and complexity.

Open: ML13197A26l (PIM) Frazil lee Monitor Not Operational The team identified a finding for the licensee's failure to maintain their frazil ice detector operational. The detector was sampling a non-representative water temperature which would not have warned operators of the presence of conditions favorable for the formation of frazil ice on intake structure components. The licensee entered the issue into the corrective action program as Condition Report CR 2013-04310 and switched the points they monitored for potential frazil ice formation. This performance deficiency is more than minor, and therefore a finding, because it is associated with the configuration control attribute of the Mitigating Systems Cornerstone and affected the associated cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Using rnspection Manual Chapter 0609, Appendix G, Shutdown Operations Significance Determination Process, Attachment 1, Checklist 4, PWR Refueling Operation: RCS level> 23' OR PWR Shutdown Operation with Time to Boil > 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> And Inventory in the Pressurizer, the finding is determined to have very low safety significance (Green) because the finding did not increase the likelihood of a loss of RCS inventory; did not degrade the licensee s ability to terminate a leak path or add RCS inventory; and did not degrade the licensee s ability to recover decay heat removal, this finding did not require a Phase 2 or 3 analysis as stated in Checklist 4. This finding has a cross~cutting aspect in the area of problem identHication and resolution associated with the corrective action program component because the licensee did not take appropriate corrective actions to address a similar condition during the winter of 2011-2012 in a timely manner, commensurate with the safety signjficance and complexity.

Open: MLJ4134A4IO (PIM) Failure to Follow Procedures for Classifying Component Failures The inspectors identified a Green finding for the licensee s failure to follow a procedure for classifying component failures. Specifically, the licensee s failure to follow Procedure FCSG-69-5, Failure Identification and Reporting, is a performance deficiency. As a result, the failure of the Turbine-Driven Auxiliary Feedwater Pump, FW-10, to start on demand was not identified as a functional failure. Subsequently, the licensee properly evaluated the system perfonnance taking into consideration the functional failure. The licensee documented the finding in the corrective action program as Condition Report 2014-04217. The performance deficiency is more than minor, and therefore a finding, because ifleft uncorrected the performance deficiency could have the potential to lead to a more significant safety concern. The inspectors evaluated the finding using Inspection Manual Chapter 0609, Appendix A, The Significance Determination Process For Findings At-Power, Exhibit 2, Mitigating Systems Screening Questions, dated June 19, 2012. The finding is of very low safety significance (Green) because it did not affect the design or qualification of a mitigating system, structure, or component (SSC), represent a loss of system function, or loss of function of single or multiple trains of equipment. The finding had a human performance cross-cutting aspect associated with training because the licensee failed to provide adequate training to the engineering staff.

VJJ14UUI,;. VVCU .:>HQ water pump AC-1 OC. The licensee subsequently implemented these changes. The performance deficiency is more than minor because it is related to the Equipment Performance attribute of the Mitigating Systems cornerstone and adversely affected the cornerstone objective to ensure the reliability of systems that respond to initiating events to prevent undesirable consequences, in that the failure to implement the required procedure and setpoint changes increased the likelihood that the affected raw water pump cable would become inoperable after significant rainfall or flooding. The inspectors performed an initial screening of the finding in accordance with NRC Manual Chapter IMC 0609, Appendix A, The Significance Determination Process (SDP) for Findings At-Power. Using IMC 0609, Appendix A, Exhibit 2, Mitigating Systems Screening Questions, dated July I, 2012, this finding is of very low safety significance (Green) because it: ( l) was not a deficiency affecting the design or qualification of a mitigating system; (2) did not represent a loss of system and/or function; (3) did not represent an actual loss of function of a single train for greater than its technical specification allowed outage time; and (4) does not represent an actual loss of function of one or more non-technical specification trains of equipment designated as high safety-significant in accordance with the licensee s maintenance rule program for greater than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. The finding has a cross-cutting aspect in the Human Performance area associated with the Avoiding Complacency aspect because operators did not recognize and plan for the possibility of mistakes and assumed that the necessary procedural and alann setpoint changes had been made.

Open: ML15!28AJ80 (PIM) Failure to Conduct and Evaluate Simulator Testing In Accordance with ANSI/ANS-3.5-2009 The inspectors identified a Green finding with four examples for failing to conduct and evaluate simulator performance testing in accordance with the standards of ANSI/ANS-3.5-2009. Specifically, the licensee failed to do the following: Set initial reactor power at 15 percent in accordance with plant design for all performances between 1990 and 2014 of Transient (6), Main Turbine Trip from Maximum Power Level That Does Not Result in Immediate Reactor Trip Set the instantaneous main turbine load reduction to 10 percent as supported by design basis data in the 20 L4 performance of Transient ( 11 ), Maximum Design Load Rejection Evaluate the results of the 100 percent power Steady-State Perfonnance Test using the correct acceptance criteria in accordance with the standard, Appendix B, Section B.1.1 Evaluate all transient test results versus acceptance criteria 4.1.4(1) in accordance with the standard, Appendix B, Section B.1.2 After NRC identification of the transient test issues, licensee evaluation revealed that the initial conditions for Transients (5) and (10) were in error as well. The licensee initiated corrective action documented in condition reports 2014-14190, 2014-14208; and 2015-02547. The licensee s failure to conduct and evaluate perfom1ance testing in accordance with the ANST/ANS-3.5-2009 standard as endorsed by Regulatory Guide 1.149, Revision 4, was the performance deficiency. Per licensee Procedure TQ-AA-306, Simulator Management, the licensee uses ANSI/ANS-3.5-2009 as the standard for their simulator testing.

The perfonnance deficiency is more than minor because if left uncorrected, the perfonnance deficiency could have become more significant in that not completing the required simulator testing correctly can lead to not detecting and correcting errors in the simulator so it actually models the plant correctly. This can both leave the potential for negative training of licensed operators and call into question the ability to conduct valid licensing examinations with the simulator. Using Manual Chapter 0609, Significance Determination Process, Attachment 4, Tables 1 and 2 worksheets, and the corresponding Appendix I, Licensed Operator Requalification Significance Determination Process (SDP), Flowchart Block No.14, the finding was detennincd to have very low safety significance (Green) because it dealt with deficiencies associated with simulator testing, modification, and maintenance and there was no evidence that the plant-referenced simulator does not demonstrate the expected plant response or have uncorrected modeling and hardware deficiencies. This finding has a cross-cutting aspect in the change management area of human performance, associated with leaders using a systematic process for evaluating and implementing change so that nuclear safety remains their overriding priority. There were efforts on-site to change to the 2009 version of the standard as early as 2011, but the efforts were rescinded by plant management in December 2011 for unknown reasons. When they officially switched from the 1985 to the 2009 version of the standard (on March l , 2013), there is no evidence an effective change management plan was implemented. Efforts to transition between the testing and maintenance requirement djfferences were complicated by lack of allocating necessary resources to support this

uynam1c weo :)Jte effort. There was minimal simulator staffing during the extended plant outage (April 2011 to December 2013), and no effective plan to deal with knowledge management to compensate for simulator employee turnover. Internal audits in May 2014 and October 2014 found numerous issues with their simulator testing and configuration management program, many of which could have been averted or addressed earlier with an effective transition plan in place.

Open: MLl5l06A89 1 (PIM) Failure to Account for Elevated Battery Room Temperature Effects on Battery Service Life Green. The team identified a Green finding for the licensee s failure to verify or check the adequacy of design of the 125 Vdc batteries from environmental effects. Specifically, the licensee failed to account for the effects of elevated battery room temperature on expected battery service life, in accordance with EPRI Standard TR-100248, Stationary Battery Guide: Design Application, and Maintenance, Revision 2. Tn response to this issue, the licensee performed an immediate operability determination to evaluate the effects of the elevated battery room temperatures and to determine when to modify the testing frequency based on the shorter life of the batteries. This finding was entered into the licensee s corrective action program as Condition Report CR 2015 02390. The team determined that the failure to account for elevated battery room temperature effects on battery sernce life was a performance deficiency. This finding was more than minor because it was associated with the design control attribute of the Mitigating Systems cornerstone and adversely affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to events to prevent undesirable consequences. Specifically, if left uncorrected, it could lead to a more significant safety concern in that the batteries could fail to maintain sufficient capacity and go undetected when testing at the normal 5 year interval. 1n accordance with Inspection Manual Chapter 0609, Appendix A, The Significance Determination Process (SDP) for Findings At-Power, dated June 19, 2012, Exhibit 2, Mitigating Systems Screening Questions, the issue screened as having very low safety significance (Green) because it was a design or qualification deficiency that did not represent a loss of operability or functionality; did not represent an actual loss of safety function of the system or train; did not result in the loss of one or more trains of non-technical specification equipment; and did not screen as potentially risk significant due to seismic, flooding, or severe weather. This finding had a crosscutting aspect in the area of problem identification and resolution associated with operating experience because the licensee failed to evaluate and implement the EPRI standard based on industry experience when measuring room temperature readings above the optimal battery room temperature.

Open: ML l3221A584 (PIM) Failure to Adequately Plan and Control Work Activities to Maintain Doses ALA.RA The inspectors reviewed a self-revealing finding of very low safety significance involving the licensee s failure to adequately plan and control work activities relating to the Chemical Volume Control System piping to maintain doses ALARA. Specifically, the work was fast-tracked, which caused issues with the understanding of the work scope and led to the mismanagement of foreseeable aspects in the ALARA planning process. In response, the licensee evaluated their ALA.RA process and entered the issue into their corrective action program as Condition Report 2012-20825. The failure to maintain doses ALARA due to inadequate planning was a performance deficiency. The performance deficiency is more than minor because it negatively affected the Occupational Radiation Safety Cornerstone, in that inadequate planning led to increased collective radiation dose for occupational workers. This resulted in a finding because no violation of regulatory requirements occurred, but the licensee failed to meet a self-imposed standard. The Occupational Radiation Safety Cornerstone was affected; therefore, the inspectors used Manual Chapter 0609, Appendix C, Occupational Radiation Safety Significance Determination Process, dated August 19, 2008, to determine the significance of the finding. The finding had very low safety significance because although the fmding involved ALARA planning and work controls, the licensee s latest three-year rolling average collective dose was less than 240 person-rem. This finding had a cross-cutting aspect in the human performance area, 1ttn://cioQ.nrc.t>nv/nrr-nffice/ms/clvn/rrm irl .cfmf06/17/201 S 4:~0: 17 PMl

Open: MLl2079A224 (PIM) Fort Calhoun Station, 2011, Biennial Problem Identification and Resolution Inspection Summary Overall, the NRC noted deficiencies in all three areas of the problem identification and resolution process. Most significantly, the licensee sown root cause assessment of the external flood protection violation concluded that they had not been effective in ensuring that the associated performance deficiencies were adequately identified, evaluated, and resolved, and that these same performance deficiencies also extended into other station activities and could impact overall station performance a significant condition adverse to quality. This is a concern because problem identification and resolution is one of the primary reactor oversight process crosscutting areas that the NRC defines as the fundamental performance attribute that extends across all cornerstones of safety. The NRC identified that the licensee failed to correct this condition, identify the cause, and preclude recurrence as required. The team noted that while the licensee was identifying and placing a large number of adverse conditions into the corrective action process (nearly 21,000 in two and a half years), the associated corrective actions were often narrowly focused and failed to adequately identify the extent of cause and extent of condition, where required. The team also identified that due to the lack of an effective trending program, the licensee failed to identify degrading performance and therefore was unable to take action prior to the manifestation of conditions adverse to quality. Furthermore, the team identified numerous condition reports whose prioritization was inconsistent with the condition described. Examples included inoperable safety related equipment classified as broke-fix, contrasted with a minor personal injury, which resulted in an extensive root cause analysis. Several workers commented that everything was classified a priority, and therefore; nothing was a priority. In fact, the licensee classified 65 condition reports as significant conditions adverse to quality during the inspection period. roughly four times the typical number. Additionally, the team found examples of repetitive failures that were indicative of programmatic inadequacies. These examples included the failure to adequately utilize industry operating experience, inadequacies in the implementation of the corrective action program which was narrowly focused on resolving discrete conditions, and limited use of 10 CFR Part 21 reportability issues, which were typically closed without appropriate systematic equipment evaluation considerations.

Non-Cited Violation Initiating Events 02/02/2012 FCS *SCWE:N *HP:Y *PIR: N Docket/Status: 05000285 (C)

Open: MLl2079A224 (PIM) Failure to Follow Housekeeping Program Requirements The NRC identified a Green non-cited violation of l OCFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, for the failure to properly implement procedural requirements to control transient equipment and materials. Specifically, on November 14, 2011, the team identified loose maintenance carts, improperly stored ladders, excessive transient combustible material, inadequately evaluated scaffolding being stored near safety-related equipment, and a procedure which failed to provide gujdance for inspection and removal of foreign material in the spent fuel pool as a result of a non-functional skimmer. The repeated failures of plant personnel to follow the procedural requirements for the control of transient materials were perfonnance deficiencies.

The finding was more than minor because if left uncorrected, the deficiencies could lead to a more significant safety concern. The finding is of very low safety significance because it did not represent a loss of system safety function, did not represent the actual loss of safety function of a single train for greater than its technical specification allowed outage time, and did not screen as potentially risk significant due to a seismic, flooding, or severe weather initiating event. This finding has a crosscutting aspect in the corrective action program component of the problem identification and resolution area because the licensee failed to track and trend information from the corrective action program hftn://cio9.nrc.1>ov/nrr-nffice/ms/clvn/ron irl .cfmf06/ 17/20 l .'i 4:JO: 17 PM1

Open: MLI2l87A79Q (PIM) TNADEQUATE PROCEDURES WITH FIVE EXAMPLES FOR THE INITTATTNG EVENTS CORNERSTONE The team identified a finding of very low safety significance involving a non-cited violation of Title 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, with five examples. Example 1: Alarm Response Procedure ARP-CB-10, 11/A 12 for a main feed water pump trip does not provide guidance that the auxiliary lube oil pump must be started prior to starting the main feed water pump. After identification, the licensee entered the issue into the corrective action program as Condition Report 2012-03140. Example 2: Alarm Response Procedure ARP-CB-l ,2,3/A2 provides inadequate instructions for restoration of letdown following a controller or instrument failure that causes letdown isolation. After identification, the licensee entered the issue into the corrective action program as Condition Report 2012-03140. Example 3: Alarm Response Procedure ARP-AI-66A/A66A does not contain guidance to determine if an auxiliary feed water actuation is inadvertent nor does it contain guidance to enter AOP-28, Auxiliary Feed water System Malfunctions, if the operators determine that the actuation is inadvertent. After identification, the licensee entered the issue into the corrective action program as Condition Report 2012-03140. Example 4: Alarm Response Procedure ARP-CB-1,2,3/AJ does not contain guidance for entering AOP-35, "Reactor Coolant Pump Malfunctions," when there is a seal cooler leak. After identification, the licensee entered the issue into the corrective action program as Condition Report 2012-03140. Example 5: Alarm Response Procedure ARP-CB-l,2,3/A2 does not contain any procedural guidance for a failure of the VCT level instrument.

After identification, the licensee entered the issue into the corrective action program as Condition Report 2012-03140. These failures to prescribe activities affecting quality by procedures or to include appropriate acceptance criteria are performance deficiencies. Each example is more than minor and therefore a finding because it adversely affects the procedure quality attribute of the initiating events cornerstone objective to limit the likelihood of those events that upset plant stability and challenge critical safety functions during shutdown as well as power operations.

These examples either could have significantly affected, or were shown during examination preparation and administration to have actually affected the operator s ability to perform the activity affecting quality. In accordance with Inspection Manual Chapter 0609, Attachment 4, Phase 1 Initial Screening and Characterization of Findings, a phase l screening was performed and each example except for Example l was determined to be of very low safety significance (Green) because each example does not contribute to both the likelihood of a reactor trip and

  • the likelihood that mitigation equipment or functions will not be available. For Example 1, a phase 1 screening was performed and the finding was determined to contribute to both the likelihood of a reactor trip and the likelihood that mitigation equipment or functions will not be available and required a phase 3 analysis. A senior reactor analyst determined that the finding was of very low safety significance because the calculated bounding delta core damage frequency was 1.4 E-7. The finding has a cross-cutting aspect in the area of problem identification and resolution associated with the corrective action program component because the licensee did not implement a corrective action program with a low threshold for identifying issues in that licensed operators deviate from procedures when procedw-es cannot be implemented as written without writing necessary condition reports to fix the deficient procedures.

Open: ML12118A34I (PIM) Untimely Corrective Actions for 480 VAC Breaker Issues The NRC identified a noncitcd violation (NCV) of 10 CFR Part 50, Appendix B, Criterion XVI, Corrective Actions, for the failure to take timely corrective actions with respect to nonconforming conditions in several circuit breakers. These conditions were determined to have been the cause of the 1B4A bus bar failure that initiated a fire on httn://cin9.nrc.o-nv/nrr-nffice/m~clvn/ron irl .cfml 06/17/201 'i 4 :10: 17 PMl

Dynamic Web Site June 7, 2011. These conditions were not corrected in a timely manner and the licensee continued to operate with a degraded breaker for nine months after the breaker tripped unexpectedly during the June 7, 2011, fire event. The licensee entered this issue into their corrective action program as CRs 2012-01884 and 201 l-5414. The violation was detennined to be more than minor because it affected the Initiating Events Cornerstone attribute of protection against external events (i.e., fire). The issue adversely affected the associated cornerstone objective of limiting the likelihood of those events that upset plant stability and chalJenge critical safety functions during shutdown as well as power operations because the condition that contributed to the fire event was left uncorrected. The finding screened to Green in accordance with IMC 0609, Appendix G because RCS makeup capability was not degraded.The inspectors detennined that the issue had a cross-cutting aspect in the area of Human Performance, Decision Making, in that the licensee failed to use conservative assumptions and adopt a requirement to demonstrate that the proposed action is safe in order to proceed rather than a requirement to demonstrate that it is unsafe in order to disapprove the action (H.l.b).

Open: ML1304'i8055 (PIM) Hot Work Procedures Allowed a Roving Fire Watch The inspectors identified a Green non-cited violation of Technical Specification 5.8. J.c for the failure to maintain written procedures covering fire protection program implementation. Specifically, the licensee changed the hot work procedure to allow a roving fire watch in lieu of the continuous fire watch required by the fire protection program.

The licensee entered this issue into their corrective action program as Condition Report 2012-19945. The failure to maintain written procedures covering fire protection program implementation was a performance deficiency. This finding was more than minor because it was associated with the procedure quality attribute of the Initiating Events cornerstone and it adversely affected the cornerstone objective oflimiting the likelihood of events that upset plant stability and challenge critical safety functions during shutdown as well as power operations. The inspectors evaluated the risk significance of this finding using Manual Chapter 0609, Appendix F, Fire Protection Significance Determination Process, because the performance deficiency involved a failure to adequately implement fire prevention and administrative controls for hot work activities. A senior reactor analyst performed a limiting Phase 3 evaluation and determined this finding had very low risk significance (Green). The finding did not have a cross-cutting aspect since it was not indicative of present performance.

Open: MI ,I 3192A501 (PIM) HPSI Pump Flow Imbalance The NRC identified a non-cited violation of Technical Specification 5.8.1.a for failure to establish, implement, and maintain a procedure recommended in Regulatory Guide 1.33, Revision 2, Appendix A. Specifically, the licensee failed to establish a procedure for changing load on the Main Turbine as required by Section 2.f, Changing Load or Load Follow. The licensee entered this into their corrective action program as Condition Report 2013-08572.

Failure to comply with technical specifications is a performance deficiency. The finding is more than minor because it adversely affects the Procedure Quality attribute of the Initiating Events Cornerstone objective to limit the likelihood of events that upset plant stability and challenge critical safety functions during shutdown as well as power operations. Using the Initiating Events Screening Questions in Manual Chapter 0609, Appendix A, Exhibit 1, the finding was determined to not contribute to both the likelihood of a reactor trip and the likelihood that mitigation equipment or functions would not be available; therefore, the finding is of very low safety significance. This finding was determined to have a cross-cutting aspect in the area of human performance, associated with resources, because the licensee failed to ensure that procedures are available and adequate to assure nuclear safety. Specifically, the licensee did not establish a quality procedure for changing load on the Main Turbine as recommended by Regulatory Guide 1.33, Revision 2, Appendix A.

Open: ML12079A224 (PIM) Failure to Establish Adequate Measures to Maintain Vendor Manual Design Control Information The NRC identified a non-cited violation of 10 CFR Part 50, Appendix B, Criterion III, Design Control, for the failure to establish adequate measures for the selection and review for suitability of application of parts equipment, and processes that are essential to the safety-related function of structures, systems, and components. Specifically, the team identified numerous condition reports involving inadequate implementation of vendor manual infonnation that affected the suitability of application of parts equipment, and processes that are essential to the safety-related function of structures, systems, and component repair and refurbishment activities over an extended period. The failure to properly maintain design information associated with vendor manuals to ensure information, which affected the suitability of application of parts equipment, and processes, essential to the safety-related function of structures, systems, and component repair and refurbishment activities, was a performance deficiency. The performance deficiency was detennined to be more than minor because it was associated with the design control attribute of the Mitigating Systems Cornerstone, and affected the associated cornerstone objective to ensure availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences, and was therefore a finding. The finding has very low safety significance because it did not represent a loss of system safety function, did not represent the actual loss of safety function of a single train for greater than its technical specification allowed outage time, and did not screen as potentially risk significant due to a seismic, flooding, or severe weather initiating event. This finding has a crosscutting aspect in the decision making component of the human performance area because the licensee failed to make safety-significant decision using a systemic process which included formally defining the authority and roles for decisions in that the licensee chose not to fill key positions responsible for the program for several years.

Specifically, on December 1, 2011, the team identified a deficiency regarding the licensee s inability to implement adequate procedures for gathering, analyzing, and commtmicatiog information related to low-level perfonnance vulnerabilities and repeat occurrences prior to the emergence of more significant events. The failure to implement adequate procedures to trend conditions adverse to quality is a performance deficiency. The finding affected the Mitigating Systems Cornerstone and was more than minor because if left uncorrected, the deficiency could lead to a more significant safety concern. The finding has very low safety significance because it did not represent a loss of system safety function, c.tid not represent the actual loss of safety function of a single train for greater than its technical specification allowed outage time, and did not screen as potentially risk significant due to a seismic, flooding, or severe weather initiating event. This finding has a crosscutting aspect in the corrective action program component of the problem identification and resolution area because the licensee failed to thoroughly evaluate problems associated with the trending program such that the resolutions address causes and extent of conditions, as necessary.

Open: ML12165A258 (PIM) ALTERNATE SHUTDOWN PROCEDURE DOES NOT ACCOUNT FOR SINGLE WORST CAST SPURIOUS ACTUATIONS The inspectors identified a non-cited violation with two examples related to the failure to establish an alternate shutdown capability that met the requirements of License Condition 3.D and the performance criteria in 10 CFR Part 50, Appendix R, Section III.L. Specifically, the licensee failed to establish an alternate shutdown capability that accounted for the effects of an inadvertent safety injection actuation signal and failed to ensure the plant parameters remained similar to those experienced during a loss of normal a.c. power following single spurious component actuations. The failure to meet the performance goals prescribed by the alternate shutdown capability was a performance deficiency. The perfonnance deficiency was more than minor because it was associated with the protection against external events (fire) attribute of the Mitigating Systems Cornerstone and it adversely affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. The inspectors evaluated this deficiency using Inspection Manual Chapter 0609, Appenclix F, Fire Protection Significance Determination Process. The perfonnance deficiency affected the fire protection defense-"iU depth strategies involving post-fire safe shutdown systems. Because Appendix F does not address control room fire scenarios, a senior reactor analyst evaluated the significance of this performance deficiency. This findirtg was evaluated using the process in Inspection Manual Chapter 0609, Attachment 4, Phase I Initial Screening and Characterization of Findings, and was determined to be of very low safety significance because the finding was not a design deficiency, confirmed not to result in loss of functionality, d1d not result in loss of a system safety function, did not result in loss of the safety function for a single train, did not result in loss of safety function for maintenance rule equipment, and did not potentially affect risk significant external initiating events. Because the *original failure to comply with the regulations had occurred longer than three years prior to this inspection, this finding did not reflect current licensee perfomiance.

Specifically, the licensee rev1sed procedure steps to open the breakers for the reactor coolant gas vent system valves in response to Non-cited Violation 05000285/2008009 02; however, the licensee did not revise the procedures until March 24, 2012, after the inspectors requested to review the corrective actions for the 2008 violation. The failure to take timely corrective action to address inadequate procedure guidance to safely shutdown the plant following a fire was a performance deficiency. The finding was more than minor because it was associated with the protection against external events (fire) attribute of the Mitigating Systems Cornerstone and it adversely affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to in1tiating events to prevent undesirable consequences. This finding was evaluated using the Fire Protection Significance Detcnnination Process and was detem1ined to be of very low safety significance because of the design of the vent system valves (i.e., three spurious actuations needed to exceed charging pump capability), availability of reliable reactor coolant system pressure and pressurize level indications in the control room, and the ability of the operator to compensate for the deficiency because of their experience and familiarity. This finding had a cross-cutting aspect in the area of human performance associated with decision making because the licensee did not use a systematic process to correct fire protection procedure deficiencies in response to a violation in 2008.

Failure to comply with technical specifications was a performance deficiency. The perfonnance deficiency is more than minor and therefore a finding because it adversely impacted the equipment performance attribute of the Mitigating Systems Cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Using the Significance Determination Process Phase 1 and 2 Worksheets, the finding was determined to affect the loss of system safety function and required entry into Appendix A of this process for screening. The senior reactor analyst screened the issue based on a less than one-hour exposure time and determined that the finding was of very low safety significance (Green) because the calculated bounding delta core damage frequency was 1 E-8. The finding has a cross-cutting aspect in the area of work control because the licensee failed to plan work activities to support long-term equipment reliability by not limiting safety system unavailability, specifically the Safety Injection Tanks.

Example 1: There is no procedure guidance provided for tripping b1stabtes on a trip unit if required for any instrument failure other than nuclear instrumentation. The annunciator response procedures only provide guidance to bypass the trip unit. After identification, the licensee entered the issue into the corrective action program as Condition Report 2012-03140.

Example 2: Abnormal Operating Procedure AOP-15, Loss of Flux Indication or Flow Streaming does not provide guidance during a nuclear instrument failure for tripping only those trip units that need to be tripped and bypassing the others. After identification, the licensee entered the issue into the corrective action program as Condition Report 2012-03141.

Example 5: Operating Instruction OI-SI-1 , Safety Injection Normal Operation, Attachment 4, Filling SI Tank(s) Using HPS1 Pumps, does not contain sufficient guidance for operators to successfully fill the safety injection tank using high pressure safety injection pumps. After identification, the licensee entered the issue into the corrective action program as Condition Report 2012-03139.

Example 6: The licensee failed to include directions in Alarm Response Procedure ARP-CB- I 0, 11 /A 12, to set the 43FW switch to OFF prior to attempting a manual start of the standby condensate pump when the auto-start feature fails to start the standby pump. This switch must be placed in OFF before the standby condensate pump can be started.

These goals shall be established commensurate with safety and, where practical, take into account industry-wide operating experience. Specifically, from March of 2012 until October of 2012, the licensee allowed the maintenance rule program to deteriorate by not performing initial screenings in a timely fashion (some were being done months later) and the actual evaluation of the equipment status was not being done at all for eight months.

Consequently, several components including electrical relays and electrical load centers were not characterized in a timely fashion. Also, the licensee was not implementing the operating experience program as required by this regulation. The licensee chose to stop perfom1ance of level 1 and level 2 operating experience evaluations by direction from the senior management in August of 2012 because of concerns over resources for recovery. Several examples where operating experience was not done correctly that subsequently led to equipment issues included the containment spray pump low oil issues (ACA 2008-5695), vendor manual updates, and loose fasteners (both electrical and mechanical) from San Onofre Nuclear Generating Station Licensee Event Reports 3612007005, 3612007006, and 3612008006. This finding was entered into the licensee s corrective action program as Condition Report CR 2012-17572. The team determined that the failure to adequately implement the maintenance rule was a performance deficiency.

Open: ML13070A399 (PIM) Two Examples of Failure to Obtain Prior NRC Approval for Flooding Mitigation Strategies The inspectors identified two examples of a Severity Level IV violation of 10 CFR 50.59, Changes, Tests and Experiments, and associated Green findings for the licensees failure to appropriately perform written evaluations for two changes for flooding mitigation strategies. In the first example, the licensee changed the Updated Safety Analysis Report and Abnormal Operating Procedure 01 (AOP-01), Acts of Nature, to incorporate use of back.flow through the circulating water system for a flow path for raw water. In the second example, the licensee was implementing a flooding mitigation modification which would have used components which did not meet full quality requirements for their Safety Class 3 designated function. Had the licensee appropriately evaluated these two changes, they would have determined that a license amendment was required for implementation of both changes since both resulted in more than a minimal increase in the likelihood of occurrence of a malfunction of a system, structure, or component important to safety. The failure to perform adequate written evaluations of changes in accordance with 10 CFR 50.59(d)(l) was a performance deficiency. This performance deficiency was of more than minor safety significance because it was associated with the human perfonnance attribute of the mitigating systems cornerstone and it adversely affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. In accordance with the NRC Enforcement Policy, the inspectors used MC 0609, Significance Determination Process, Appendix A, Exhibit 2, to determine the final significance of the finding. For the back flow through the circulating water system example, the finding represented a potential loss of the intake structure due to flooding; therefore, a Phase 3 evaluation by a senior reactor analyst was necessary. The senior reactor analyst evaluated a bounding risk analysis case which assumed that the raw water system and offsite power were lost. This bounding case had an incremental conditional core damage probability of 5.0 x L0-7, and therefore the finding was determined to have very low safety significance (Green). For the trash rack blowdown modification example, the inspectors determined the finding was of very low safety significance (Green) because the finding was a design deficiency that did not result in the loss of functionality. The NRC s significance determination process (SDP) considers the safety significance of findings by evaluating their potential safety consequences. The traditional enforcement process separately considers the significance of willful violations, violations that impact the regulatory process, and violations that result in actual safety consequences. Traditional enforcement applied to this finding because it involved a violation that impacted the regulatory process. Assessing the violation in accordance with Enforcement Policy, the inspectors determined it to be of Severity Level IV because it resulted in a condition evaluated by the SDP as having very low safety significance (Example 6.1.d.2 of the NRC Enforcement Policy). The inspectors determined the Green finding had a cross-cutting aspect in the area of problem identification and resolution because the licensee failed to thoroughly evaluate problems such that resolutions address the causes and extent of condition specifically associated with deficiencies involving the Acts of Nature procedural guidance P.1(c)

(I) was not a deficiency affecting the design or 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 arnowed outage time; (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 licensee s maintenance rule program; and (5) did not involve the loss or degradation of equipment or function specifically designed to mitigate a seismic, flooding or severe weather event. This finding has a cross-cutting aspect in the area of human performance associated with the decision-making component because the licensee failed to use conservative assumptions in decision-making and adopt a requirement to demonstrate that the proposed action is safe in order to proceed rather than a requirement to demonstrate it is unsafe in order to disapprove the action .

Specifically, prior to March l ,

2013, the licensee failed to correct the procedural inadequacies associated with Procedure FCSG-24-3, Condition Report Screening, Revision 3, as identified in the root cause analysis for Condition Report CR 2012-09494. This issue has been entered into the corrective action program as Condition Report CR 2013-04380. This performance deficiency is more than minor, and therefore a finding, because if left uncorrected, inadequate corrective action program procedures could become a more significant safety concern. This finding is associated with the Mitigating Systems Cornerstone. Since the finding was discovered while in a shutdown condition, the team used Manual Chapter 0609, Appendix G, Shutdown Operations Significance Determination Process, and determined tl1e finding to have very low safety significance (Green) because the finding did not increase the likelihood of a loss of RCS inventory, the finding did not degrade the licensee s ability to terminate a leak path or add RCS inventory when needed, and the finding did not degrade tbe licensee s ability to recover decay beat removal once it was lost.

This finding has a cross-cutting aspect in the area of problem identification and resolution associated with the corrective action program component because the licensee failed to implement a corrective action program with a sufficiently low threshold. Specifically, although the licensee identified significant flaws in FCS procedures while perfonning the RCA for Condition Report CR 2012-09494, the licensee failed to initiate the appropriate corrective action documents to drive the necessary procedure changes.

The team identified a non-cited violation of 10 CFR 50.55a, Codes and Standards, for the failure of the licensee to follow the ASME Code when establishing new reference curves as corrective action to address the performance of component cooling water pump AC-3A within the low required action range of the inservice testing program.

Specifically, on July 29, 2011 , the licensee failed to follow ASME Code, Subsection ISTB 6200(c), in that, the new reference curves were established without performing an analysis which included verification of the pump s operational readiness at a pump level and a system level, without determining the cause of the change in pump performance, and without an evaluation of all trends indicated by available data. The team confirmed that while the pump was inoperable from an inservice testing perspective during this period, required surveillance testing showed that pump flows and differential pressures were still sufficient to meet the assumptions used in the FCS safety analysis. This issue has been entered into the corrective action program as Condition Report CR 2013-04010. This performance deficiency is more than minor, and therefore a finding, because it is associated with the human perfoimance attribute of the Mitigating Systems Cornerstone, and affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences.

The licensee modified Calculation EA-FC~92-072 to address the team s concerns. This issue has been entered into the corrective action program as Condition Report CR 2013-09817. The performance deficiency is more than minor, and therefore a finding, because it is associated with the equipment performance attribute of the Mitigating Systems Cornerstone and adversely affected the cornerstone objective to ensure the availability, reliability and capability of systems that respond to initiating events to prevent undesirable consequences. Because this performance deficiency affected the calculation used to determine the require diesel fuel oil inventory for an accident or a loss of offsite power occurring from at power conditions, the team used Manual Chapter 0609, Appendix A, The Significance Determination Process for Findings At-Power, and determined the finding to have very low safety significance (Green) because it: (1) was not a deficiency affecting the design or 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; (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 licensee s maintenance rule program; and (5) did not involve the loss or degradation of equipment or function specifically designed to mitigate a seismic, flooding or severe weather event. This finding has a cross-cutting aspect in the area of problem identification and resolution associated with the corrective action program component because the licensee failed to thoroughly evaluate the condition identified in Condition Report CR 2013,04594 to detennine its impact to emergency diesel generator fuel oil consumption.

Specifically, from June 7, 2011, to the present, the licensee failed to monitor the performance of the 480 Vac busses in a manner sufficient to provide reasonable assurance that they are capable of fulfiJling their intended safety functions. This issue has been entered into the corrective action program as Condition Report CR 2013-04352. This performance deficiency is more than minor, and therefore a finding, because it is associated with the equipment performance attribute of the Mitigating Systems Cornerstone and affected the associated cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences.

Technical Specification 2.7, Electrical Systems, stated that the reactor shall not be heated up or maintained at temperatures above 300 degrees Fahrenheit unless the electrical systems listed in that section [includes the 480 V bussesJare operable. Because the plant was maintained below 300 degrees during the exposure period, the team determined that power availability Technical Specifications were being met as discussed in Checklist 4. Because the finding did not increase the likelihood of a loss of RCS inventory; did not degrade the licensee s ability to terminate a leak path or add RCS inventory; and did not degrade the licensee s ability to recover decay heat removal, this finding did not require a Phase 2 or 3 analysis as stated in Check.list 4. Therefore, the finding is determined to have very low safety significance (Green). This finding has a cross-cutting asp~ct in the area of human performance associated with the decision-making component because the licensee failed to use conservative assumptions in decision-making and adopt a requirement to demonstrate that the proposed action is safe in order to proceed rather than a requirement to demonstrate it is unsafe in order to disapprove the action.

Specifically, from June 2008, the licensee did not evaluate a change that would permanently substitute manual actions for an automatic action to add water and nitrogen gas to the component cooling water surge tank, which is an updated safety analysis report described design function for the component cooling water system. The licensee entered this condition into their corrective action program and planned to perform an evaluation to determine if prior NRC review and approval is needed for this design change. This issue has been entered into the corrective action program as Condition Report CR 2013-04417. The team determined that it was reasonable for the licensee to be able to foresee and prevent the occurrence of this deficiency. The team evaluated this performance deficiency as both a traditional enforcement violation, and a reactor oversight process finding. The violation of 10 CFR Part 50.59 was more than minor because it involved a change to an updated safety analysis report design function in that there was a reasonable likelihood that the change would require NRC review and approval. This finding is associated with the Mitigating Systems Cornerstone. The team used the NRC Enforcement Manual and Inspection Manual Chapter 0609, Attachment 4, Initial Characterization of Findings, to evaluate this issue. The finding is determined to have very low safety significance (Green) because it was a design deficiency confirmed not to result in the loss of operability or functionality. The violation of 10 CFR 50.59 impacted the ability of the NRC to perform its regulatory oversight function and was determined! to be Severity Level IV because the resulting changes were evaluated by the significance determination process as having very low safety significance, in accordance with the NRC Enforcement Policy. The NRC concluded that the finding did not reflect current licensee performance.

Open: MLl3197A261 (PIM) Inadequate Root Cause for a Significant Condition Adverse to Quality The team identified a non-cited violation of 10 CFR Part 50, Appendix B, Criterion XVI, Corrective Action, associated with the licensee s failure to promptly identify, correct, and prevent recurrence of a significant condition adverse to quality. Specifically, from November 2009 to present, measures established by the licensee failed to assure that the cause of an identified significant condition adverse to quality was corrected and corrective actions taken would preclude repetition. This issue has been entered into the corrective action program as Condition Report Condition Report CR 2013-04037. The performance deficiency is more than minor, and therefore a finding, because it is associated with the protection against external factors attribute of the Mitigating Systems Cornerstone, and affected the associated cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Additionally, if left uncorrected, the licensee s RCA will not provide assurance that effective corrective actions are taken to preclude recurrence of a breaker trip failure.

Technical Specification 2.7, Electrical Systems, states that the reactor shall not be heated up or maintained at temperatures above 300 degrees Fahrenheit unless the electrical systems listed in that section [includes the 480 V busses] are operable. Because the plant was maintained below 300 degrees during the exposure period, the team determined that power availability technical specifications were being met as discussed in Checklist 4. Because the finding did not increase the likelihood of a loss of RCS inventory; did not degrade the licensee s ability to terminate a leak path or add RCS inventory; and did not degrade the licensee s ability to recover decay heat removal, this finding did not require a Phase 2 or 3 analysis as stated in Checklist 4. Therefore, the finding is determined to have very low safety significance (Green).

Specifically, during the course of the inspection, the team identified four specific examples where licensee staff failed to conduct a thorough operating experience review while performing a root cause analysis to determine whether the same or similar problems have occurred at Fort Calhoun or within the industry. Therefore, this finding is indicative of a programmatic issue. Thorough operating experience reviews are important for the construction of corrective actions to prevent the issues from recurring and help determine extent of condition and/or generic implications from the issue. This issue was entered into the licensee s corrective action program as Condition Report CR 2013-14205. The licensee s programmatic failure to conduct adequate operating experience reviews for root cause evaluations was a performance deficiency. This performance deficiency is more than minor, and therefore a finding, because if left uncorrected it has the potential to lead to a more significant safety concern.

Specifically, if thc licensee does not thoroughly evaluate operating experience to determine whether the same or similar problems have occurred at the Fort Calhoun Station or within the industry, then effective corrective actions to prevent the issues from recurring may not be implemented and an adequate extent of condition and/or generic implications from the issue may not be identified.

The licensee did not protect the cables for both pumps AC-1 OA and AC-1OB from any credible fire in the intake structure. This issue was entered into the licensee s corrective action program as Condition Report CR 2013-16201. The failure to translate Appendix R license exemptions into the fire protection program design was a performance deficiency. This performance deficiency was more than minor, and therefore a finding, because it was associated with the protection against external factors attribute of the Mitigating Systems Cornerstone and affected the associated objective to ensure availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Using Inspection Manual Chapter 0609, Appendix F, Fire Protection Significance Determination Process, dated September 20, 2013, Step 1.3, the team determined that the reactor would have been able to reach and maintain cold shutdown, therefore, this finding was determined to have very low safety significance (Green).

There was no cross-cutting aspect assigned to this finding because the original license exemption request and grant was over three years ago and this issue does not reflect present licensee performance.

Specifically the U-bolt design was non-conservative with respect to the design basis requirements. The licensee entered these issues into the corrective action program as CR 2013-03 722. The licensee revised the calculation to support operability. in addition, the licensee generated engineering change EC59570 to fix the degraded VAS-I and VAS-2 supports.

Open: MLl 4 128A3 14 (PIM) Failure to Maintain Design Control of HPSI Injection Valve (Section 40A3.4)

Two examples of a non-cited violation of IO CFR 50, Appendix B, Criterion lll, Design Control, were identified.

The first example involved the failure to establish procedures or Technical Specifications to accomplish required HPSI injection flow balancing. The second example involved the failure to provide controls or testing to ensure that replacement parts for HPSI injection valves were suitable for the application and were capable of supporting the safety-related functions of the HPSI system. The licensee has since implemented Engineering Change 59874 which included throttling of the HPSl loop injection valves. This change was completed on August 20, 2013, restoring the original plant design and overcoming the configuration control errors introduced on three of the eight injection valves. Post-work testing for the completed modification included flow balance testing for the HPSJ loop injection lines. The inspectors reviewed the results of this testing and detennined that the UFSAR assumptions regarding balanced loop flows were adequately addressed by licensee corrective actions. This finding was more than minor because it adversely impacted the design control attribute of the Mitigating Systems Cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. The inspectors reviewed NRC IMC 0609, Attachment 4, Initial Characterization of Findings, Table 3 SDP Appendix Router. While this issue was identified during a refueling outage, the inspectors determined that the majority of the exposure time for this violation occurred with the reactor at power. As such, the inspectors determined the finding could be evaluated using the SDP in accordance with IMC 0609, The SOP for Findings at-Power, Appendix A, Exhibit 2, Mitigating Systems Screening Questions. The inspectors answered yes to the question of Does the finding represent a loss of system and/or function? The inspectors determined the finding required a detailed risk evaluation per I MC 0609 Paragraph 6.0, because the operability of the high pressure safety injection system (both trains) was in question. A Region IV senior reactor analyst performed a detailed risk evaluation and determined the flow imbalance did not result in a loss of safety function. Since the high pressure safety injection system was capable of meeting the functional success criteria, there was no quantifiable change to the core damage frequency and therefore was determined to be of very low safety significance (Green).

Open: MLl4128A314 (PlM) Failure to Request a License Amendment for Required Change to Technical Specifications (Section 40A3.4)

A Severity Level IV non-cited violation of IO CFR 50.59, Changes, Tests, and Experiments, and an associated Green finding was identified involving the failure to request a license amendment for a faci lity change tlhat required a change to the Technical Specifications. This issue is also associated with a Green finding related to the licensees failure to follow Procedure NOD-QP-3, 10 CFR 50.59 and IOCFR 72.48 Reviews, and Procedure FCSG-23, IO CFR 50.59 Resource Manual, both of which require submittal of a license amendment request prior to making a facility change that requires a change to Technical Specifications. The licensee initiated CR 20 14-01029 on January 23, 20 14, to document this violation and track corrective actions. This performance deficiency was considered to be of more than minor safety significance because it was associated with the procedure quality attribute of the mitigating systems cornerstone and it adversely affected the cornerstone objective to ensure the availability, reliability, and capability of systen1s that respond to in.itiating events to prevent undesirable consequences. Speci-fically, the failure to follow station procedures for the IOCFR 50.59 process caused the Technical Specifications to become insufficient to ensure that the limiting conditions for operation will be met. Using Inspection Manual Chapter 0609 Appendix G, Checklist 4, the inspectors detem1ined that the finding did not result in the loss of any accident mitigation capability and did not requ ire a quantitative risk assessment. This finding was determined to be of very low risk significance.

Th is performance deficiency was also determined to be subject to traditional enforcement because it impeded the regulatory process, in that the failure to submit a license amendment and add req uired surveillance testing was in violation of 10 CFR 50.59(c)(l)(i) and caused the NRC-approved Technical Specifications to be o ut of alignment with the safety analysis for the faci lity. This violation is associated with a finding that has been evaluated by the SDP and communicated with an SOP color reflective of the safety impact of the deficient licensee perfonnance. The SDP, however, does not specifically consider the regulatory process impact. Thus, although related to a common regulatory concern, it is necessary to address the violation and finding using different processes to con-ectly reflect both the regulatory importance of the violation and the safety significance of the associated finding. This violation was determined to be a Severity Level JV violation, because it is consistent with the examples in Paragraph 6. 1.d of the NRC Enforcement Policy. The finding had a cross-cutting aspect in the training aspect of the human perfom1ance cross-cut6ng area because the licensee s staff failed to understand and misapplied NRC generic guidance related to discovery of inadequate Technical Specifications.

A non-cited violation of 10 CFR 50, Appendix B, Criterion lll, Design Control, was identified involving the failure to translate the High Pressure Safety Injection (HPSI) pump design and runout characteristics to design documents such as the Updated Safety Analysis Report or design calculations. On June 2 1, 2013, the licensee completed Engineering Change 59874, which permanently installed flow-limiting orifices in the discharge line of each pump, effectively preventing HPSI runout condi tions from occurring for all plant conditions. This finding was more than minor because it adversely impacted the design control attribute of the Mitigating Systems Cornerstone objective of ensuring the availability, reliabili ty, and capability of systems that respond to initiating events to prevent undesirable consequences. The inspectors reviewed NRC lMC 0609, Attachment 4, Initial Characterization of Findings, Table 3 SOP Appendix Router. While this issue was identified during a refueling outage, the inspectors determined that the majority of the exposure time for this violation occurred with the reactor at power. As

Dynamic Web Site such, \he inspectors detennined \he finding should be evaluated using the SOP in accordance with IMC 0609, The Significance Determination Process (SOP) for Findings at-Power, Appendix A, Exhibit 2, Mitigating Systems Screening Questions. The finding required a detailed risk evaluation because the high pressure safety injection system was inoperable for some of the large break loss of coolant accident scenarios (at reactor pressures less than 100 psi). A Region IV senior reactor analyst performed a bounding detailed risk evaluation. The change to the core damage frequency was 8E-8/year and, therefore, detenn ined to be of very low safety significance (Green). The dominant core damage sequences included loss of coolant accidents where the high and low pressure safety injection systems fa iled during recirculation. The non-degraded low pressure safety injection system contributed to minimize the risk. The inspectors detennined there was no cross-cutting aspect associated with this finding because events related to identification of needed procedures and specifications occurred in the 1970 sand are not indicative of current performance. (Section 40A3.2).

Open: ML14128A3 l4 (PIM) Inadequate IO CFR 50.59 Screening for Containment Spray Design Change (Section 40A3.8 A non-cited violation of IO CFR 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings was identified involving the licensee s failure to complete a IO CFR 50.59 screening that met the requirements of Procedure NOD-QP-3, 10 CFR 50.59 and IO CFR 72.48 Reviews, Revision 37. The licensee s staff subsequently re-perfonned the 50.59 screening on November 29, 2013, and dete.n nined that a IO CFR 50.59 evaluation was requi red. The NRC staff reviewed the IO CFR 50.59 screening and evaluation and detennined that they had been properly perfonned, and that a license amendment request was not required prior to implementation of the activity. The li censee documented this procedural violation in CR 2014-01357 on January 29, 2014. This perfonnance deficiency was considered to be of more than minor safety significance because it was associated with the design control attribute of the mitigating systems cornerstone and it adversely affected the cornerstone objective to ensure the availabili ty, reliabili ty, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifi cally, the fai lure to follow station procedures for the 10 CFR 50.59 process prevented the licensee s staff from evaluating the adverse impacts of the change on the facility. Using Inspection Manual Chapter 0609 Appendix G, Check list 4, the inspectors detennined that the finding did not result in the loss of any accident mitigation capability and did not require a quantitative risk assessment. This finding was detennined to be of very low risk significance. The inspectors determined that this finding had a cross-cutting aspect of conservative bias in the human performance area, because the licensee s staff ensured that the proposed design change was safe in order to proceed rather than unsafe to stop [H.14]. (Section 40A3.8).

Open: MLl4l 15A41 l (PIM) Fai lure to Follow Operability Procedure The inspectors identified two examples of a non-ci ted violation of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, associated with the licensee s failure to follow Station Procedure NOD-QP-31, Operability Detennination Process, when evaluating deficiencies associated with inadequate tornado missile protection for required components. Specifically, Step 4.3. 15 required, in part, that, A positive detennination of operabi lity must be justified, including a technical discussion of why the concern identified does not prevent the item from fulfilling its intended safety function. In each example, the team identified that the operability detennination Jacked adequate technical justification for why the item was operable with the degraded or nonconfonning condition. The licensee addressed these issues by taking corrective actions that provided adequate tornado missile protection in accordance with design basis requirements. The licensee entered this deficiency into its conective* action program for resolution as Cond ition Reports CR 20 I 3-15429 and 2013-14006.

This perfonuance deficiency is more than minor, and therefore a finding, because it is associated with the equipment performance attribute of the Mitigating Systems Cornerstone, and affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Since the finding involving inadequate operability determinations occurred while in a shutdown condition, the team used Manual Chapter 0609, Appendix G, Shutdown Operations Significance Determination Process, and determined the finding to have very low safety significance (Green) because the finding did not increase the likelihood of a loss of reactor coolant system inventory, the finding did not degrade the licensee s ability to tenninate a leak path or add reactor coolant system inventory when needed, and the finding did not degrade the licensee s ability to recover decay heat removal once it was lost. This finding has a cross-cutting aspect in the area of human performance associated with the decision-making component because the licensee failed to use conservative assumptions in decision making when performing operability determinations.

Open: ML14 11 5A41 l (PIM) Failure to Promptly Identify and Correct a Condition Adverse to Quality The team identified a non-cited violation of 10 CFR Part 50, Appendix B, Criterion XVI, Corrective Actions, involving the failure to promptly identify and correct a condition adverse to quality. Specifically, from August 2005 to July 15, 2013 the licensee failed to promptly identify and correct inadequate Class 1 structures wall thickness deficiencies to protect systems and components contajned within from tornado generated missiles. The Jicensee resolved this issue by implementing changes to the facility through a licensing amendment that was reviewed and approved by the NRC. This issue has been entered into the corrective action program as Condition Report CR 2013-14363. The licensee s failure to promptly identify and correct conditions adverse to quality was a performance deficiency. This performance deficiency is more than minor, and therefore a finding, because it is associated with the design control attribute of the Mitigating Systems Cornerstone, and affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Using Inspection Manual Chapter 0609, Appendix A, The Significance Determination Process for Findings at Power, the finding was determined to have very low safety significance (Green) because it: (1) was not a deficiency affecting the design or 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; (4) did not represent an actual loss of function of one or more non-technical specification trains of equipment designated as high safety-significance in accordance with the licensee s maintenance rule program; and (5) did not involve the loss or degradation of equipment or function specifically designed to mitigate a seismic, flooding, or severe weather event.

The team determined this finding has a cross-cutting aspect in the area of human performance associated with the decision-making component involving the failure to use conservative assumptions in decision-making and adopt a requirement to demonstrate that the proposed action is safe in order to proceed rather than a requirement to demonstrate it is unsafe in order to disapprove the action. Specifically, in 2005 the licensee identified that wall thicknesses for areas of the auxiliary building and intake structure were less than design requirements. The licensee failed to enter this deficiency into the corrective action process and inappropriately used an alternate acceptance criteria that was not part of the facility licensing basis.

Open: ML14318A886 (PIM) Failure to Initiate Condition Reports for Gaps Identified in Resolving NRC Non-Cited Violations A non-cited violation of 10 CFR Part 50, Appendix B, Criterion V, Instruction, Procedures, and Drawings, was identified involving the failure to follow procedures to initiate condition reports to enter conditions adverse to quality into the corrective action program. Specifically, the licensee failed to initiate condition reports in accordance with Procedure FCSG 24-1 , Condition Report Initiation, Step 4.1.1.G, when deficiencies related to the station s corrective actions implemented for NRC violations were identified. The licensee entered this issue into its corrective action program as Condition Report 2014-09063 and initiated action to write condition reports for identified gaps related to previous NRC violations. This perfom1ance deficiency was more than minor, and therefore a finding, because if left uncorrected, it would have the potential to lead to a more significant safety concern. The team performed an initial screening of the finding in accordance with NRC Manual Chapter IMC 0609, Appendix A, The Significance Determination Process (SOP) for Findings At-Power. Using IMC 0609 Appendix A, Exhibit 2, Mitigating Systems Screening Questions, dated July 1, 2012, this finding was of very low safety significance (Green) because it did not involve a loss or degradation of equipment or function specifically designed to mitigate a seismic, flooding, or severe weather initiating event.

Specifically, the licensee failed to maintain available a flexible suction hose related to the reactor coolant system beat removal mitigating strategy. The licensee initiated Condition Report 2014-08876 to address this deficiency and initiated action to procure and replace the missing flexible suction hose. This perfonnance deficiency was more than minor, and therefore a finding, because it was associated with the equipment performance attribute of the Mitigating Systems Cornerstone, and adversely affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences (i.e. core damage). The NRC detennined that this finding was of very low safety significance (Green) using NRC Manual Chapter IMC 0609, Appendix L, B.5.b Significance Determination Process, because it resulted in an unrecoverable unavailability of an individual mitigating strategy but did not result in multiple unavailable mitigating strategies such that reactor coolant system heat removal could not occur. This finding has a crosscutting aspect in the area of human performance in that the licensee s inadequate B.5.b inventory procedure contributed to the lack of recognition that the degraded flexible suction hose was required to implement mitigating strategies.

Open: ML14329B361 (PIM) Failure to Maintain Design Control of the Auxiliary Feedwater System The team identified a non-cited violation of 10 CFR Part 50, Appendix B, Criterion Ill, Design Control, associated with the licensee s failure to maintain design control of the auxiliary feedwater system. Specifically, the licensee implemented a modification to the facility that involved the installation of flood.barriers surrounding the guard pipes and portions of the steam driven auxiliary feedwater pump steam supply Jines that are below the evaluated flood height in Room 81. This modification would have acted like a catch basin and potentially caused the steam driven auxiliary feedwater pump (FW-10) to be inoperable during a high energy line break event. The licensee implemented a facility modification to protect the steam supply piping and vent holes from water intrusion. The licensee entered this deficiency into their corrective action program for resolution as Condition Report CR 2013-22770. The failure to maintain design control of the auxiliary feedwater system was a performance deficiency. The performance deficiency was more than minor, and therefore a finding, because it was associated with the design control attribute of the Mitigating Systems Cornerstone and affected the associated objective to ensure availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences.

Specifically, the flood barrier installed only protected the FW-10 steam supply from flood waters rising from the floor; however, this water is postulated from a high energy line break, which would both spill onto the floor and spray into Room 81 without regard for direction. This resulted in a condition where the steam driven auxiliary feedwater pump may not have been able to perform its specified safety function. The team evaluated the finding using Inspection Manual Chapter (IMC) 0609, Appendix A, The Significance Determination Process (SOP) for Findings at Power, dated June 19, 2012, and determined that this finding required a detailed risk evaluation because the turbine driven auxiliary feedwater pump was inoperable for longer than the technical specification allowed outage time. A regional senior reactor analyst performed a detailed risk evaluation and determined that the finding was of very low safety significance (Green) because the bounding change to the core damage frequency was approximately 1.2£-9/year. The dominant core damage sequences included feedwater and main steam line breaks with the consequential failure of the turbine driven auxiliary feedwater pump combined with other random failures of Train A and B equipment trains. Equipment that helped mitigate the risk included the diesel driven and motor-driven auxiliary feedwater pumps, which remained functional for the vast majority of sequences. The finding was determined to have a cross-cutting aspect in the area ofproblem identification and resolution associated with the corrective action compone11t because the licensee did not take appropriate corrective actions to address safety issues, in that, an additional modification was required to protect the FW-10 steam supply from the effects of a high energy line crack or break.

Dynamic Wei> Si'te The team identified a non-cited violation of 10 CFR Part 50, Appendix B, Criterion XVI, Corrective Actions, associated with the licensees failure to adequately evaluate and take prompt corrective actions to address an identified condition adverse to quality related to the internal flooding analysis for Room 81 of the Auxiliary building.

SpecificaHy, the team could not 1ocate the analyses for water level in Room 81 following a high energy line break in the room. This deficiency had previously been identified by the licensee and entered into its corrective action program, however, it was improperly closed without completing the analysis. The licensee performed operability assessments for the affected areas that established a reasonable expectation for operability pending final resolution of the problems. The licensee entered this deficiency into their corrective action program for resolution as Condition Report CR 2013-11831. The licensees failure to adequately evaluate and take prompt corrective ac6ons to address an identified condition adverse to quality related to the internal flooding analysis for Room 81 was a performance deficiency. The performance deficiency was more than minor, and therefore a finding, because it was associated with the design control attribute of the Mitigating Systems Cornerstone and affected the associated objective to ensure availability, reliability, and capability of systems that responds to initiating events to prevent undesirable consequences. Spedfically, the licensee failed to take prompt corrective actions to address an identified condition adverse to quality related to the internal flooding analysis for Room 81 of the Auxiliary building. Using Inspection Manual Chapter 0609, Appendix A, The Significance Determination Process (SOP) for Findings At-Power, Exhibit 2, Mitigating Systems Screening Questions, dated July l , 2012, inspectors 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 allowed outage time, or two separate safety systems out-of-service for longer than their technical specification allowed outage time; and (4) does not represent an actual loss of function of one or more non-technical specification trains of equipment designated as high safety-significant for greater than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> in accordance with the licensee s maintenance rule program.

Open: ML14329B361 (PIM) Failure to Recognize Adverse Design Changes The team identified a non-cited violation of 10 CFR Part 50, Appendix B, Criterion III, Design Control, associated with the licensee s failure to maintain design control of the auxiliary feedwater system. Specifically, the licensee implemented a modification to the facility that placed vent holes in the steam supply line guard piping for the steam driven auxiliary feedwater pump which were located below the evaluated flood height in Room 81 and potentially rendered the pump inoperable. The licensee implemented a facility modification to protect the vent holes from water intrusion. The licensee entered this deficiency into their corrective action program for resolution as Condition Reports CR 2013-18308 and CR 2013-18605. The failure to ensure that design requirements were correctly translated into installed plant equipment was a performance deficiency. The performance deficiency was more than minor, and therefore a finding, because it was associated with the design control attribute of the Mitigating Systems Cornerstone and affected the associated objective to ensure availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, the licensee s failure to translate the design requirements into insta1led plant equipment resulted in a condition where the steam driven auxiliary feedwater pump may not have been able to perform its specified safety function. The team evaluated the finding using Inspection Manual Chapter (IMC) 0609, Appendix A, The Significance Determination Process (SOP) for Findings at Power, dated June 19, 2012, and determined that this finding required a detailed risk evaluation because the turbine driven auxiliary feedwater pump was inoperable for longer than the technical specification allowed outage time. A regional senior reactor analyst performed a detailed risk evaluation and determined this finding to be of very low safety significance (Green) because the bounding change to the core damage frequency was approximately l .2E-9/year.

Specifically, the licensee failed to verify that all inputs used in the thermal lag analysis for the environmental qualification program were representative of the most limiting condition. The licensee perfonned an operability determination for the affected areas that established a reasonable expectation for operability pending resolution of the problems. The licensee entered this deficiency into their corrective action program for resolution as Condition Report CR 2013-14504, and CR 2013-14168. The failure to verify that all inputs used in the thermal lag analysis for the environmental qualification program were representative of the most limiting condition was a performance deficiency. The performance deficiency was more than minor, and therefore a finding, because it was associated with the design control attribute of the Mitigating Systems Cornerstone and affected the associated objective to ensure availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, the performance deficiency called into question the availability and reliability of components required to mitigate the effects of a high energy line break. Using Inspection Manual Chapter 0609, Appendix A, The Significance Determination Process (SDP) for Findings At-Power, Exhibit 2, Mitigating Systems Screening Questions, dated July 1, 2012, inspectors determined that the finding was of very low safety significance (Green) because the finding: (l) was not a deficiency affecting the design and qualification of a mitigating structure, system, or component, and did not result in a Joss 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 allowed outage time, or two separate safety systems out-of-service for longer than their technical specification allowed outage time; and (4) does not represent an actual loss of function of one or more non-technical specification trains of equipment designated as high safety-significant for greater than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> in accordance with the licensee s ma1ntenance ruJe program.

Open: MLl4329B361 (PlM) Use of Non-conservative Values in Design Analyses The team identified two examples of a non-cited violation of l OCFR Part 50, Appendix B, Criterion III, Design Control, associated with non-conservative errors identified in station calculations. Specifically, the licensee failed to use the yield strength for the most limiting type steel installed in the facility when evaluating changes to the chemical and volume control system, and failed to ensure that the acceptance criteria used for seismic anchors and supports verified that they were within the design requirements. The licensee perfonned an operability determination for the affected areas that established a reasonable expectation for operability pending final resolution of the problems. This issue was entered into the licensee s corrective action program as Condition Report CR 2013-2857.

The use of non-conservative values in station design analyses is a perfom1ance deficiency. This performance deficiency was more than minor, and therefore a finding, because it is associated with the design control attribute of the Mitigating Systems Cornerstone and affected the associated objective to ensure availability, reliabil.ity, and httn://cinQ.nrc.('ov/nrr-oflice/m!\/ctvn/ron irl cfmr06/l 7/201.'i 4:JO: 17 PMl

Dynamic Web Site capabihty of systems that respond to initiating events to prevent undesirable consequences. SpecificaJJy, the licensee s use of non-conservative yield strength to analyze the pipe break loads during a high energy line break resulted in a condition where structures, systems, and components necessary to mitigate the effects of a high energy pipe break may not have functioned as required. Additionally, the failure to use appropriate acceptance criteria resulted in a condition where structures, systems and components may not have functioned as designed during a seismic event. Using Inspection Manual Chapter 0609, Appendix A, The Significance Determination Process (SDP) for Findings At-Power, Exhibit 2, Mitigating Systems Screening Questions, dated July 1, 2012, the inspectors 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 allowed outage time, or two separate safety systems out-of-service for longer than their technical specification allowed outage time; and (4) does not represent an actual loss of function of one or more non-technical specification trains of equipment designated as high safety-significant for greater than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> in accordance with the licensee s maintenance rule program. The finding has a cross-cutting aspect in the area of human performance associated with the resources component because the licensee failed to maintain long tenn plant safety by maintenance of design margins. Specifically, Calculation FC 07885 failed to use the most limiting yield strength when detennining potential pipe break loads which resulted in a reduction of design margin.

Open: MLI5043A423 (PIM) Failure to Establish Appropriate Preventive Maintenance and Failure to Identify Raw Water SSC Maintenance Rule Performance Criteria Exceeded and thereby establish Monitoring Requirements for the SSC The inspectors identified an NCV of very Jow safety significance of 10 CFR 50.65 paragraph (a)(2) Requirements for Monitoring the Effectiveness of Maintenance of Nuclear Power Plants, because the licensee did not demonstrate that performance of an SSC was being effectively controlled through appropriate preventive maintenance and did not monitor the performance of the SSC against licensee-established goals to provide reasonable assurance that the SSC was capable of fulfilling its intended function. Specifically, the licensee failed to demonstrate that tbe performance of HCV-2875A was being effectively controlled through appropriate preventive maintenance and failed to monitor HCV-2875A perfoIDJance against Jfoensee established goals when performance criteria were exceeded. Corrective actions taken for this violation included revising the Maintenance Rule perfonnance criteria assessment for this SSC, classifying the SSC as 10 CFR 50.65 (a)(l), and specifying goals, corrective actions and monitoring for the system.

The inspectors determined that the licensee s failure to demonstrate SSC performance through appropriate preventive maintenance and the failure lo identify that system perfonnance criteria had been. exceeded and, as a result, the failure to perfonn an evaluation of the system for 50.65 (a)(l) goals, corrective actions, and monitoring, was a performance deficiency within tl1e licensee s ability to foresee and correct and should have been prevented.

Traditional enforcement did not apply as the issue did not have actual or potential safety consequences, had no willful aspects, and did not impact the NRC s ability to perform its regulatory function. A review of NRC Inspection Manual Chapter (IMC) 0612, Appendix E, Minor Examples, revealed that no minor examples are applicable to this finding. The finding is more than minor because it is associated with the Equipment Performance attribute of the Mitigating Systems cornerstone and adversely affected the Cornerstone objective to ensure the reliability of systems that respond to initiating events to prevent undesirable consequences. Specifically, the failure to demonstrate HCV-2875A performance through appropriate preventive maintenance had a direct impact on HCV-2875A performance and the reliability of the raw water system. In addition, the failure to identify that HCV-2875A performance criteria had been exceeded and thereby the failure to perform an evaluation for 50.65 (a)(l) goals and to specify corrective actions and implement monitoring when the functional failure was first identified, resulted in a delayed assessment of this SSC and additional failures occurred in the intervening timeframe which adversely affected the reliability of the raw water system. The inspectors performed an initial screening of the finding in accordance with NRC IMC 0609, Appendix A, the Significance Determination Process (SDP) for Findings at Power. Using IMC 0609, Appendix A, Exhibit 2, Mitigating Systems Screening Questions, dated July 1, 2012, this finding is of very low safety ht1n://cio9.nrc gov/nrr-office/ms/<ivn/rnn ir I .cfmron/17/201 'i 4:10: 17 PMl

Specifically, the licensee failed to complete an operability determination related to Condition Report 2014-13202 in accordance with Procedure OP-FC-108-1 I 5, Operability Detenninations, Revision l. Consequently, after discovering dry boric acid accumulation at a welded joint on the high pressure safety injection pump discharge casing vent valve piping, the licensee exited the operability detennination procedure prematurely, without performing an engineering evaluation for potentially degraded safety-related piping. The failure to perform operability determinations in accordance with documented procedures is a performance deficiency. This performance deficiency is more than minor, and therefore a finding, because it affected the human performance attribute of the Mitigating Systems cornerstone objective to ensure the availabrnty, reliability, and capability of systems that respond to initiating events. Using Inspection Manual Chapter 0609, Appendix A, Exhibit 2, Mitigating Systems Screening Questions, the team determined that the finding was of very low safety significance (Green) because all questions in Exhibit 2 could be answered in the negative. The team determined that the most significant contributor to the finding was that the licensee failed to stop when faced with the uncertain condition of the boric acid accumulation on the pump vent valve piping and resolve the issue prior to continuing (H.11 ).

On October 27, 2014, a condition report was written to investigate dry boric acid on the high pressure safety injection Pump SI-2B vent valve piping. The initial investigation concluded that no degraded or nonconforming condition existed. On October 29, 2014, the Boric Acid Corrosion Control Program engineer conducted a review of the dry boric acid residue. The engineer identified the boric acid appeared to originate from a weld and needed to be cleaned and repaired; however, the engineer failed to initiate a condition report documenting this condition adverse to qualilty. The failure to promptly identify and correct a condition adverse to quality in accordance with IO CFR Part 50, Appendix B, Criterion XVI, Corrective Action, was a perfonnance deficiency.

The licensee failed to include the raw water pumps discharge check valves allowable back leakage acceptance criteria into the design calculation. In response to this issue, the licensee performed an operability determination and verified that with the current back leakage flow rates all downstream safety related loads would be properly cooled. This finding was entered into the licensee s corrective action program as Condition Reports CR 2015-01801, and CR 2015-01835. The team determined that the failure to verify the adequacy of the raw water system design through calculational methods or through a suitable test program was a perfonnance deficiency. This finding was more than minor because it was associated with the design control attribute of the Mitigating Systems Cornerstone and adversely affected the cornerstone objective to ensure the reliability, availability and capability of systems that respond to initiating events to prevent undesirable consequences.

The team identified two examples of a Severity Level IV, Green, non-cited violation, of 10 CFR 50.59, Changes, Tests and Experiments, for the licensee s failure to obtain a license amendment prior to implementing a change if the change would result in a departure from a method of evaluation described in the updated safety analysis report. Specifically, on February 23, 2015, and March 10, 2015, the licensee changed the facility to incorporate increased seismic damping for use in the intake crane and intake superstructure seismic analysis and seismic design; and in the raw water piping seismic analysis, respectively. ln response to this issue, the licensee declared the intake structure as operable but non-conforming pending resolution of a license amendment request to permit the use of the increased damping value; and declared the raw water system as operable but non-conforming pending completion of the corrective actions to determine what actions are necessary to restore compliance to the licensing basis. This finding was entered into the licensee s corrective action program as Condition Reports CR 2015-02224 and CR 2015-02842. The team determined that the failure to identify that the proposed change to incorporate increased seismic damping for use in the intake crane and intake superstructure seismic analysis and seismic design; and in the raw water piping seismic analysis, was a perfonnance deficiency.

This finding was also evaluated using traditional enforcement because it had the potential for impacting the NRC s ability to perform its regulatory function. This finding was more than minor because it was associated with the design control attribute of the Mitigating Systems cornerstone and adversely affected the cornerstone objective to ensure the reliability, availability and capability of systems that respond to initiating events to prevent undesirable consequences; and there was a reasonable likelihood that the change would have required NRC review and approval prior to implementation. Specifically, the licensee failed to determine that the proposed updated safety analysis report change, and associated design calculations, did involve a change to a structure, systems, or components such that it did adversely affect an updated safety analysis report described design function; less conservative seismic damping values, which required an evaluation to be performed. In accordance with Inspection Manual Chapter 0609, Appendix A, The Significance Determination Process (SOP) for Findings At-Power, dated June 19, 2012, Exhibit 2, Mitigating Systems Screening Questions, the issue screened as having very low safety significance (Green) because it was a design or qualification deficiency that did not represent a loss of operability or functionality; did not represent an actual loss of safety function of the system or train; did not result in the loss of one or more trains of non-technical specification equipment; and did not screen as potentially risk significant due to seismic, flooding, or severe weather. Since the vioJation is associated with a Green reactor oversight process violation, the traditional enforcement violation was determined to be a Severity Level IV violation, consistent with the example in paragraph 6.l.d(2) of the NRC Enforcement Policy. This finding had a crosscutting aspect in the area of human performance associated with design margins because individuals failed to ensure margins were carefully guarded and changed only through a systematic and rigorous process.

SpecificaJJy, prior to March 13, 2015, the Hcensee failed to perform an adequate design review to upgrade the auxiliary building single failure proof crane capacity, by failing to comply with ASME NOG-1-2004, Rules for Construction of Overhead and Gantry Cranes (Top Running Bridge, Multiple Girder). In response to this issue, the licensee perfonned an operability determination and concluded that the crane was operable but non-confonning, and limited the use of the main hook to the original 75 ton value until the long term actions can be completed to restore the crane to fully operable. This finding was entered into the licensee s corrective action program as Condition Report CR 2015-02718. The team determined that the failure to perform an adequate design review to upgrade the auxiliary building single failure proof crane capacity was a performance deficiency. This finding was more than minor because it was associated with the design control attribute of the Mitigating Systems cornerstone and adversely affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to events to prevent undesirable consequences. Specifically, the licensee failed to comply with ASME NOG l 2004 requirements to ensure the auxiliary building crane remained elastic when subjected to design loads for safe load handling of heavy loads. In accordance with Inspection Manual Chapter 0609, Appendix A, The Significance Determination Process (SDP) for Findings At-Power, dated June I9, 2012, Exhibit 2, Mitigating Systems Screening Questions, the issue screened to Exhibit 4, External Events Screening Questions, because it was a function specifically design to mitigate a seismic event. Per Exhibit 4 the issue screened to a more detailed risk evaluation because if the seismic function were assumed to be completely failed and a load were dropped it would impact the spent fuel pool cooling or the safety injection refueling water storage tank functions. Therefore, the Region IV senior reactor analyst performed a more detailed risk evaluation.

Given that the frequency of the initiating event is less than 1 x 10-6, the analyst determined that the finding was of very low safety significance (Green). The team determined that this finding did not have a crosscutting aspect because the most significant contributor did not reflect current licensee performance.

Specifically, prior to February 25, 2015, the licensee failed to follow Procedure FCSG-56, Time Critical Operation Standard, to ensure aU time critical operator actions were validated and verified. In response to this issue, the licensee determined that the continual training of job performance measures tJ1at test competency in completing many of the time critical actions provides a basis that all times are achievable. This finding was entered into the licensee s corrective action program as Condition Report CR 2015-02443. The team determined that the inadequate implementation of Procedure FCSG-56 for validation and verification of operator time critical actions was a performance deficiency. This finding was more than minor because it was associated with the human performance attribute of the Mitigating Systems cornerstone and adversely affected the cornerstone objective.to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, the licensee did not adequately implement Procedure FCSG-56 to ensure that all operator time critical actions listed in Attachment 1 were properly validated and verified; therefore the licensee could not demonstrate that all operator time critical actions could be executed in accordance with the design pasis.

Open: ML15128A180 (PIM) Failure to Implement Risk Management Actions for Planned Maintenance Activities Green. The inspectors identified an NCV of very low safety significance of 10 CFR 50.65 paragraph (a)(4)

Requirements for Monitoring the Effectiveness of Maintenance of Nuclear Power Plants, because the licensee did not effectively manage the increase in risk that resulted from maintenance activities. Specifically, the licensee failed to implement key risk management actions outlined in site risk assessment and management guidance for diesel driven auxiliary feedwater (AFW) pump maintenance that resulted in a Yellow risk configuration. This violation was entered into the licensee s corrective action program and actions taken for this violation included verifying that all remaining online work prior to the scheduled refueling outage was properly screened and assessed in accordance with site risk management procedures. In addition, the licensee conducted training on risk management guidance that had been recently implemented during corporate alignment for personnel involved with scheduling and operations.

The inspectors determined that the licensee s failure to implement key risk management actions outlined in site risk assessment and management guidance for diesel driven AFW pump maintenance was a performance deficiency within the licensee s ability to foresee and correct and should have been prevented. The finding is more than minor because it is associated with the Equipment Performance attribute of the Mitigating Systems cornerstone and adversely affected the cornerstone objective to ensure the availability of systems that respond to initiating events to prevent undesirable consequences. Specifically, the failure to perform maintenance on a continuous work schedule as required by site procedures resulted in a longer unavailability time of the equipment and an extended Yellow risk condition. Using NRC IMC 0609, Appendix K, Maintenance Risk Assessment and Risk Management Significance Determination Process , dated May 19, 2005, Flowchart 2, Assessment of [Risk Management Actions] , the inspectors determined the incremental core damage probability (!CDP) associated with the maintenance activity to be approximately lE-7, and therefore was determined to have a very low safety significance (Green), since the calculated ICDP was less than lE-6. Because the licensee did not use a systematic process to ensure that nuclear safety remained the overriding priority while they implemented a corporate alignment, the finding has a cross-cutting aspect in the area of Human Perfonnance, Change Management (H.3).

Open: MI, J 2l 87A790 (PIM) FAILURE TO CORRECTLY TRANSLATE THE DESIGN BASIS FOR THE CONTAINMENT SPRAY SYSTEM The team identified a*finding of very low safety significance involving a non-cited violation of Title 10 CFR Part 50, Appendix B, Criterion III, Design Control, in that, design control measures did not assure that the design basis for safety related systems were correctly translated into procedures. SpecificaHy, the licensee faiJed to correctly translate the design basis of the containment spray system into Technical Basis Document Procedure TBD-EOP-05, Uncontrolled Heat Extraction. After identification, the licensee entered this issue in the corrective action program as Condition Report 2011-06802. The failure to correctly translate the design basis of the containment spray system into an emergency operating procedure technical basis document is a performance deficiency. It is more than minor and therefore a finding because it adversely affects the procedure quality attribute of the barrier integrity cornerstone objective to provide reasonable assurance that physical design barriers protect the public from radionuclide releases caused by accidents or events. The incorrect guidance in the emergency operating procedure basis document could result in a licensed operator taking incorrect action to secure containment spray based on a faulty understanding of the expected system response. Securing containment spray during a main steam line break would challenge the safety function of the containment building, increasing the risk to public health and safety. Traditional enforcement does not apply because the issue did not have any actual safety consequences or potential for impacting the NRC's regulatory function, and was not the result of any willful violation ofNRC requirements. In accordance with Inspection Manual Chapter 0609, Attachment 4, Phase 1 Initial Screening and Characterization of Findings, a phase 1 screening was performed and the finding was determined to be of very low safety significance (Green) because the finding: (1) did not represent only a degradation of the radiological barrier function provided for the control room, or auxiliary bui !ding, or spent fuel pool; (2) did not represent a degradation of the barrier function of the control room against smoke or a toxic atmosphere; (3) did not represent an actual open pathway in the physical integrity ofreactor containment system, containment isolation system, and heat removal components; and (4) did not involve an actual reduction in function of hydrogen igniters in the reactor contairunent. There was no cross-cutting aspect assigned to this performance deficiency because it was not indicative of current plant performance.

Open: ML12187A790 (PIM) INADEQUATE PROCEDURES WlTH FOUR EXAMPLES FOR THE BARRIER INTEGRITY CORNERSTONE The team identified a finding of very low safety significance involving a non-cited violation of Title JO CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, with four examples. Example 1. The normal operating instruction for reactor coolant pumps, OI-RC-9, Reactor Coolant Pump Operation, contains pump trip requirements that conflict with the pump trip requirements provided in the Abnormal Operating Procedure AOP-35, Reactor Coolant Pump Malfunctions. After identification, the licensee entered this issue in the corrective action program as Condition Report 2012-03145. Example 2: Annunciator Response Procedure ARP-DCS-SCEAPIS incorrectly directs the operators to restore a control element assembly group to within proper overlap using manual group mode, instead of manual individual mode. After identification, the licensee entered the issue into the corrective action program as Condition Report 2011-07172. Example 3: Neither the Annunciator Response Procedure ARP-DCS-SCEAPIS, nor the control element assembly Abnormal Operating Procedure AOP-02, CEA and Control System Malfunctions, address excessive overlap between control element assembly groups caused by operator error instead of a digital control system failure. After identification, the licensee entered the issue into the corrective action program as Condition Report 2011-09653. ExampJe 4: The licensee s Abnormal Operating Procedure AOP-21, Reactor Coolant System High Activity, bas multiple values for high reactor coolant system activity requirements that conflict on whether or not it is necessary to initiate a plant shutdown. Additionally, this procedure is not current with the most recent action levels contained in S0-0-43 Fuel Reliability Management Plan. This fuel reliability httn://cio9.nrc.11ov/nrr-office/ms/clvn/rnn irl .cfmfOl'i/17/201 :'i 4:]0: 17 PMl

Dynamic Web Site management plan currently lists four action levels, while the actions in the abnormal operating procedure are based on five action levels. The fifth action level actions would not be perfonned since no fifth action level is defined in S0-0-43. After identification, the licensee entered the issue into the corrective action program as Condition Report 2012~03143. These failures to prescribe activities affecting quality by procedures or to include the appropriate acceptance criteria are performance deficiencies. Each example is more than minor and is therefore a finding because it adversely affects the procedure quality attribute of the barrier integrity cornerstone objective to provide reasonable assurance that physical design barriers protect the public from radionuclide releases caused by accidents or events.

These examples either could have significantly affected, or were shown during examination preparation and administration to have actually affected the operator's ability to perform the activity affecting quality. In accordance with Inspection Manual Chapter 0609, Attachment 4, Phase 1 Initial Screening and Characterization of Findings, a phase 1 screening was performed and each example except for Example 1 was determined to be of very low safety significance (Green) because the fuel cladding barrier was affected but did not affect the reactor coolant system or containment barriers. Example 1 was determined to be of very low safety significance (Green) because the finding: (1) did not represent only a degradation of the radiological barrier function provided for the control room, or auxiliary building, or spent fuel pool; (2) did not represent a degradation of the barrier function of the control room against smoke or a toxic atmosphere; (3) did not represent an actual open pathway in the physical integrity ofreactor containment system, containment isolation system, and heat removal components; and (4) did not involve an actual reduction in function of hydrogen ignitors in the reactor containment. The finding bas a cross-cutting aspect in the area of problem identification and resolution associated with the corrective action program component because the licensee did not implement a corrective action program with a low threshold for identifying issues in that licensed operators deviate from procedures when procedures cannot be implemented as written without writing necessary condition reports to fix the deficient procedures.

The inspectors identified a non-cited violation of very low safety significance of Technical Specification 2.8.3(4), the limiting condition for refueling operations in the spent fuel pool. 1n December 2009, the licensee performed refueling operations with the Spent Fuel Pool Area Charcoal Filtration System, V A-66, declared inoperable. The failure to establish an operable Spent Fuel Pool Area Charcoal Filtration System, VA-66, before moving spent fuel was a performance deficiency and a violation of Technical Specification 2.8.3(4). The licensee entered this issue into the corrective action program as Condition Reports 2012~08521, 2012-0836 and Licensee Event Report 2012-008-0. The perfonnance deficiency was detennined to be more than minor because it adversely impacted the attribute of the Barrier Integrity Cornerstone objective to maintain radiological filtration functionality during operations in the spent fuel pool to protect the public from radionuclide releases caused by accidents or events. Using IMC 0609 Appendix A, Barrier Integrity Significance Determination Process, the inspectors determined this finding to be of very low safety significance (Green). Although fuel movements were contrary to the licensee s technical specifications limiting condition for refueling operations, the finding represented a degradation of the radiological barrier function provided for the spent fuel pool fuel building. This finding has a cross-cutting aspect in the area of problem identification and resolution because the licensee did not effectively incorporate internal operating experience and lessons learned from previous VA-66 ventilation system failures during spent fuel pool refueling operations and plant safety. Specifically, the licensee failed to systematically collect, evaluate, and communicate to affected internal stakeholders in a timely manner relevant internal and external operating experience, P2(a)

Dynamic Web Site The NRC identified a non-cited violation of Title l OCPR Part 50, Appendix B, Criterion V, Procedures, for the failure to perfonn an adequate operability detennination as required by FCS Procedure NOD-QP-31 , Operability Determination Process. Specifically, the licensees op~rability determination for non-conforming containment internal structures failed to address that a section of the containment internal structures exceeded the allowable working stress criteria. The licensee entered this issue into its corrective action program for evaluation and review. Inspectors found that the failure to perform an adequate operability determination to specifically evaluate that the containment internal structures did not meet the design code of record was a performance deficiency. This violation is more than minor because it is associated with the desigo control attribute of the barrier integrity cornerstone and has the potential to adversely affect the cornerstone objective. The inspectors used Inspection Manual Chapter 0609, Appendix G Shutdown Operations Significance Detennination Process , to determine that the issue screened as very low safety significance (green) because it did not require a quantitative assessment per Checklist 4. This violation was determined to have a crosscutting aspect in the area of human performance associated with decision making (H.1.bJ.

Specifically, from initial construction to present, the licensee did not perform adequate analysis and/or post-accident condition functional testing of the teflon insulated and teflon sealed Conax. electrical penetration assemblies to detennine if they were suitable for expected post accident conditions. The licensee has decided to replace or cap all Teflon-insulated containment electrical penetration assemblies prior to returning to power operations. This issue has been entered into the corrective action program as Condition Report CR 2013 03571. This perfonnance deficiency is more than minor, and therefore a finding, because it is associated with the design control attribute of the Barrier Integrity Cornerstone and affected the associated cornerstone objective to provide reasonable assurance that physical design barriers (fuel cladding, RCS, and containment) protect the public from radionuclide releases caused by accidents or events. Using Inspection Manual Chapter 0609, Appendix A, The Significance Determination Process for Findings At-Power, the finding is determined to have very low safety significance (Green) because it did not represent an actual open pathway in the physical integrity of reactor containment, containment isolation system, and heat removal components. This finding has a cross-cutting aspect in the area of problem identification and resolution associated with the corrective action program component because the licensee failed to implement a corrective action program with a low threshold for identifying issues and identify such issues completely, accurately, and in a timely manner commensurate with their safety significance.

Dynamic Web Site requires procedures for performing maintenance that can affect the perfonnance of safety related equipment. The licensee documented this event in the corrective action program as Condition Report 2013-07253. The failure to follow maintenance work control procedures was a performance deficiency. The perfonnance deficiency is more than minor because it impacted the human performance attribute of the Barrier Integrity Cornerstone and affected the cornerstone objective to provide reasonable assurance that physical design barriers protect the public from radionuclide releases caused by accidents or events. At the time of the event, the raw water system was the ultimate heat sink connection to the spent fuel pool containing a full core off-load as well as previous core load spent fuel.

Using Manual Chapter 0609, Appendix G, 11 Shutdown Operations Significance Detennination Process," this finding was ofvery low safety significance because the event did not increase d1e likelihood of reactor coolant system inventory loss, did not degrade the licensee's ability to terminate a leak path or add reactor coolant system inventory when needed, and did not degrade the licensee's ability to recover decay heat removal once it was lost. The fmding has a cross-cutting aspect in the area of human performance because the licensee failed to make safety~significant decisions using a systematic process to ensure safety is maintained.

This performance deficiency is more than minor, and therefore a finding.., because it is associated with emergency response organization performance attribute of the Emergency Preparedness Cornerstone and affected the associated cornerstone objective to ensure that the licensee is capable of implementing adequate measures to protect the health and safety of the public in the event of a radiological emergency. Specifically, inaccurate emergency action levels degrade the licensee s ability to implement adequate measures to protect public health and safety. The finding was evaluated using the Emergency Preparedness Significance Determination Process, and was determined to be of very low safety significance (Green) because the finding was not a lost or degraded risk significant planning function. The planning standard function was not degraded because the Notification of Unusual Event and Alert emergency classifications would have been declared although potentially in a delayed manner. This finding was not assigned a cross-cutting aspect because the performance deficiency is not reflective of current performance.

Open: ML 131 64A i59 (PIM) Failure to Perfonn Siren Maintenance as Required by the Alert and Notification System Design Report The inspectors identified a noncited violation of 10 CFR 50.54(q)(2) for failure to follow an emergency plan meeting the planning standards of 10 CFR 50.47(b). Specifically, the licensee did not meet 50.47(b).(5) because they failed to fully implement preventative maintenance requirements of Design Report for the Outdoor Public Warning System, Revision 1, as determined by Federal Emergency Management Agency Region VII. The failure to fully implement requirements of the Federal Emergency Management Agency-approved alert and notification system design report was a performance deficiency within the licensee s control. The finding had a credible impact on the Emergency Preparedness Cornerstone objective because it involved the ability to warn the public using the primary alert and notification system. The finding is more than minor because it affected the equipment and facilities and offsite emergency preparedness cornerstone attributes. The finding was evaluated using the emergency preparedness significance determination process and detennined to be of very low safety significance because it was not a loss of the planning standard function. It was not a loss of planning standard function because deficiencies in maintenance of the alert and notification system did not degrade system performance. This finding was assigned a cross-cutting aspect of Documentation H.2(c) because the licensee did not incorporate up-to-date design documentation into working procedures.

Specifically, the licensee failed to correct deficiencies associated with team briefing and tracking in the Operations Support Center (OSC) identified as a result of exercises conducted March 27, 2012; July 17, 2012; March 5, 2013; and May 7, 2013. The inspectors determined that the licensees failure to correct deficiencies identified by licensee evalutors is a performance deficiency within the licensees control. This finding is more than minor because it affected the emergency preparedness cornerstone objective and the Emergency Response Organization Performance cornerstone attribute. This finding was evaluated using the Emergency Preparedness Significance Determination Process and was determined to be of very low safety signillcance because jt was a failure to comply with NRC requirements, was not a risk significant planning standard function, and was not a loss of planning standard function.

The finding was not a loss of planning standard function because the licensee adequately corrected some deficiencies identified in exercises conducted in 2012 and 2013. The finding was entered into the licensee s corrective action system as Condition Report 2013-22495. The fmding was assigned a cross-cutting aspect of Problem Identification and Resolution because the finding was reflective of current performance and the licensee did not take appropriate corrective action to address safety issues and adverse trends [P.l{d)].

This finding is more than minor because the issue js associated with procedure quality and offsite Emergency Preparedness cornerstone attributes and adversely affected the Emergency Preparedness cornerstone objective. The finding was evaluated using Manual Chapter 0609, Appendix B, Emergency Preparedness Significance Determination Process, dated February 24, 2014, and was determined to be of very low safety significance (Green) because it was a failure to comply with NRC requirements, was not a loss of planning standard function, and was not a degraded planning standard function. The planning standard function was not degraded because including state and local 2013 data would not have required the current emergency planning zone time estimate to be updated. Appendix E to 10 CFR 50, Section IV.5, states, in part, that during the years between decennial censuses, nuclear power reactor licensees shall estimate emergency planning zone pennanent resident population changes once a year using the most recent U.S. Census Bureau annual resident population estimate and State/local government population data, if available. Contrary to the above, Fort Calhoun Station failed in 2013 to estimate emergency planning zone permanent resident population changes using the most recent U.S. Census Bureau annual resident population estimate and State/local government population data, if available. Specifically, Fort Calhoun Station failed to determine whether State and local government population data was available prior to performing the analysis. This finding was assigned a cross-cutting aspect in the area of human performance associated with work management because the licensee failed to understand the scope of work performed by a contractor on their behalf, and failed to ensure the contractor fully complied with regulatory requirements.

Dynamic Web Site Open: MLL2366A158 (PIM) Failure to Follow Radiation Work Permit Requirements Inspectors reviewed a seJf-reveaJing Green noncited violation of Technical Specification 5.8. l.a for the failure to follow procedure requirements related to radiation work permit requirements. Specifically, workers unexpectedly created a high radiation area when working with tri nuke filter hosing while on a radiation work permit that did not allow access into a high radiatiO.\l area. Both workers received alarms on their dosimeters. The licensee entered the issue into its corrective action program for evaluation and review. The failure to foJlow a procedure was a performance deficiency. The finding was more than minor because it negatively impacted the Occupational Radiation Safety cornerstone s attribute of program and process, in that not following the requirements of the radiation work permit led to workers unplanned, unintended dose. Using NRC Manual Chapter 0609, Appendix C, Occupational Radiation Safety Significance Determination Process, the finding was determined to be of very low safety significance because: (1) it was not associated with as low as is reasonably achievable (ALARA) planning or work controls, (2) there was no overexposure, (3) there was no substantial potential for an overexposure, and (4) the ability to assess dose was not compromised. The finding has a problem identification and resolution crosscutting component associated with operating experience because the licensee didn t implement operating experience through changes to station procedures. Specifically, there was operating experience which could have prevented the issue if it had been discussed at the pre-job brief.

Open: ML1322lA584 (PIM) Failure To Post A High Radiation Area Resulting In A Dose Rate Alarm The inspectors reviewed a self-revealing non-cited violation of Technical Specification 5.11.1, which was the result of a radiation protection technician failing to monitor changing radiological conditions and post a high radiation area.

As a result, an operator entered a high radiation area with dose rates greater than 100 millirems per hour without knowing the dose rates in the area. In response, licensee representatives immediately surveyed the affected areas, posted the area as a high radiation area, documented the occurrence in the corrective action program as Condition Report 2013-02603, and prepared an Apparent Cause Analysis Report. The failure to post a high radiation area with dose rates greater than 100 millirems per hour is a performance deficiency. The perfonnance deficiency was more than minor because it was associated with the Occupational Radiation Safety Cornerstone attribute of program and process (exposure control) and adversely affected the cornerstone objective of ensuring adequate protection of worker health and safety from exposure to radfation because the failure exposed workers to higher than anticipated radiation dose rates. The Occupational Radiation Safety Cornerstone was affected; therefore, the inspectors used Manual Chapter 0609, Appendix C, Occupational Radiation Safety Significance Determination Process, dated August 19, 2008, to determine the significance of the violation. The violation had very low safety significance because: (1) it was not an as low as is reasonably achievable finding, (2) there was no overexposure, (3) there was no substantial potential for an overexposure, and (4) the ability to assess dose was not compromised. This violation had a cross-cutting aspect in the human performance area, work practices component, because the licensee failed to hold proper pre-job briefings and follow station procedures requiring monitoring of changing radiological conditions to ensure personnel did not proceed in the face of unexpected circumstances.

The failure to perform a sun,ey to evaluate the radiological conditions and potential hazard from airborne radiation is a performance deficiency. The licensee had the ability to foresee a possible intake if the survey had been properly performed. The performance deficiency was more than minor because it was associated with the Occupational Radiation Safety Cornerstone attribute of program and process (exposure control) and adversely affected the cornerstone objective of ensuring adequate protection of worker health and safety from exposure to radiation from radioactive material during routine civilian nuclear reactor operation. The Occupational Radiation Safety Cornerstone was affected; therefore, the inspectors used Manual Chapter 0609, Appendix C, Occupational Radiation Safety Significance Determination Process, dated August 19, 2008, to determine the significance of the violation. The violation had very low safety significance because: ( l) it was not an as low as is reasonably achievable finding, (2) there was no overexposure, (3) there was no substantial potential for an overexposure, and (4) the ability to assess dose was not compromised. This violation had a cross-cutting aspect in the human perfonnance area, work control component, because the licensee failed to maintain commun:ication during activities in which interdepartmental coordination was necessary to assure plant and human perfonnance, such as the need to keep personnel apprised of changing radiological conditions that affected work activities.

Open: ML14294A801 (PIM) Failure to Control an Entry to a High Radiation Area Resulting in a Dose Rate Alarm The inspectors reviewed a self-revealing, non-cited violation of Technical Specification 5.11.1. b, which resulted from an individual entering a high radiation area without being aware of the radiological conditions. Specifically, on July 19, 2013, an operator was performing valve lineup work in the reactor building. Although the operator was on a radiation work pennit that allowed access to high radiation areas, access was only allowed with knowledge of the dose rates in the areas entered. As immediate corrective actions, the radiation protection supervisors coached the operator on properly informing Radiation Protection of his plaJU1ed work areas and coached the radiation protection technician on having a more intrusive questioning attitude during briefings so that radworkers are properly infonned of all hazards and radiological conditions. This issue was documented in the licensee s corrective action program as Condition Report CR 2014-14693. The entry into a high radiation area without knowledge of the* radiological conditions is a performance deficiency and is a violation of Technical Specification 5. l l. l .b. The performance deficiency is more than minor because it is associated with the Occupational Radiation Safety cornerstone attribute of program and process (exposure control) and adversely affects the cornerstone objective of ensuring adequate protectioJJ of worker health and safety from exposure to radiation. Using Inspection Manual Chapter 0609, Appendix C, Occupational Radiation Safety Significance Determination Process, dated August 19, 2008, the inspectors determined the violation has very low safety significance because: (1) it was not an as low as is reasonably achievable finding, (2) there was no overexposure, (3) there was no substantial potential for an overexposure, and (4) the ability to assess dose was not compromised. This violation has a cross-cutting aspect in the human performance area, associated with teamwork, because the operator did not properly communicate his work locations to the radiation protection technician for briefing and the technician did not display a questioning attitude to understand the work locations for the operator to properly brief him and ensure nuclear safety was maintained.

The licensee entered these issues into the corrective action program as Condition Reports 2012-05658, 2012-05724 and 2012-05777 . The failure to establish, implement, and maintain procedures to ensure the meteorological monitoring equipment is operable and required meteorological data is reported was a perfonnance deficiency. This finding is more than minor because it affected the Public Radiation Safety cornerstone attribute of program and process. The failure to have and use applicable procedures to ensure the operability of the meteorological monitoring system and the accuracy of the Annual Radiological Effluent Release Report has the potential to impair public dose assessments of routine and accidental radioactive effluent releases. Using IMC 0609 Appendix D, Public Radiation Safety Significance Determination Process, the inspectors determined this finding to be of very low safety significance because the finding did not represent a significant degradation of the ability to assess dose to members of the public and the actual releases were well below established limits for members of the public. This fmding has a cross-cutting aspect in the human perfonnance area associated with the resources component because the licensee failed to ensure that personnel, procedures, and other resources were adequate for the operability of the meteorological monitoring system and implementation of Offsite Dose Calculation Manual requirements related to the annual effluent report, H.2(c)J Physical Protection 10/12/2012 FCS *SCWE:N *HP:Y *PIR: N Docket/Status: 05000285 (C)

Open: ML12314A408 (PIM) Failure to Adequately Compensate for a Degraded Intrusion Detection System The NRC identified a noncited violation of 10 CFR 73.55(0)(2) for the failure to establish adequate compensatory measures for a degraded Intrusion Detection System (IDS). Specifically, while testing the licensee s IDS for their 20 foot OCA barrier, the inspectors observed that the licensee had not installed TDS sensors on two OCA barrier swing gates. Due to the absence of IDS sensors on the gates, the licensee had implemented compensatory measures for the OCA barrier. However, the inspectors determined that the licensee s compensatory measures were inadequate because the time required for an adversary to penetrate the barrier was less than the frequency that the gates were being observed by security force personnel. Upon notification, the licensee immediately implemented compensatory measures that provided a level of protection necessary to detect attempted penetration of the gates and entered the issue into their corrective action program as Condition Report CR2012 07006. The finding is more than minor because it is associated with the physical protection attribute and adversely affected the security cornerstone objective to provide assurance that the licensee s security system uses a defense in-depth approach and can protect against the design basis threat of radiological sabotage from external and internal threats. It adversely affected the cornerstone objective because the failure to adequately compensate for degraded IDS on this OCA barrier constitutes a failure of the barrier s intended function and denies the security force the ability to detect, assess, and interdict a threat prior to detection at the PA barrier. In addition, the finding has a human performance cross-cutting aspect associated with decision making because the licensee did not use conservative assumptions when detennining the appropriate compensatory measures for the absence of IDE on the OCA barrier gates [Hl.(b)]

Open: MLl3115A095 (PIM) Failure to Ensure that an Unattended Opening On February 14, 2013, the NRC identified a non cited violation of 10 CFR 73 .55(i)(5)(iii) for the failure to ensure that unattended openings that intersect a security boundary such as underground pathways are protected by a physical barrier and monitored by intrusion detection equipment or observed by security personnel at a frequency sufficient to detect exploitation. Specifically, the licensee failed to account for the accuracy and precision of the instrumentation used to measure the river level resulting in the potential failure to ensure that a traversable unattended opening was observed at a frequency to detect exploitation. Upon notification of the violation, the licensee took immediate corrective actions by changing their compensatory measures procedure to take instrument margin of error into account to ensure that compensatory measures to monitor the unattended opening would be in place before the pathway became traversable. The licensee entered the issue into their corrective action program as CR 2013-02205.

The finding is more than minor because it is associated with the Physical Protection and Contingency Response attributes and adversely affected the Security cornerstone objective to provide assurance that the licensee s security system uses a defense-in-depth approach and can protect against the design basis threat ofradiological sabotage from external and internal threats. It adversely affected the cornerstone objective because the failure to adequately monitor an unattended opening could result in the failure to detect adversaries entering the PA. Tn addition, this finding has a cross-cutting aspect in the area of Problem Identification and Resolution, Corrective Action Program, because the licensee failed to thoroughly evaluate the protection of an unattended opening.

Introduction:

The NRC identified a Green NCV of 10 CFR 73.55(o)(2), because the licensee failed to have compensatory measures that provided the level of protection that is equivalent to the protection that was provided by the degraded components. (OUO ~.lU)

Analysis: The failure to have compensatory measures that provide the level of protection that is equivalent to the protection that was provided by the degraded component is a performance deficiency. It is a perfonnance deficiency because it was within the licensee s ability to foresee and correct. The performance deficiency was more than minor because it was associated with the Physical Protection System attribute and affected the security cornerstone objective to provide assurance that the licensee security system uses a defense-in-depth approach and can protect against the DBT of radiological sabotage from external and internal threats. Security findings are processed for significance through IMC 0609 Appendix, Part l. In accordance with the Baseline Security Significance Determination Process for power reactors, all findings associated with attributes of Physical Protection are processed using the significance screen for physical protection in section 0609EI-06 and figure 4. This finding did not meet the criteria listed in the significance screen and the finding was evaluated using the Physical Protection Significance Determination Process, Figure 5. The inspectors determined that the total for the finding was zero points due to no Tier elements being listed in figure 5. The inspectors detennined the finding to be of very low security significance because the calculated point did not exceed the range for a Green determination (0 to 6 points). In addition, this finding was detennined to have an associated cross-cutting aspect in Problem Identification and Resolution within the area of CAP, because the licensee failed to conduct a review of corrective actions to ensure the problems are resolved (P.l(c)]. (QPO SBQ Enforcement: Paragraph 73.55(0)(2) of 10 CFR, states in part, that compensatory measures must provide a level of protection that is equivalent to the protection that was provided by the degraded components.

Contrary to the above, the licensee did not have compensatory measures that were equivalent to the protection that was provided by the degraded components. Because this violation was of very low security significance and it was entered into the licensee. s CAP, this finding is being treated as an NCV, consistent with Section 2.3.2 of the NRC Enforcement Policy.

Open: ML13254A412 (PIM) Failure to Correct a Deficiency in the Testing of Explosive Detectors On June 19, 2013, the NRC identified a noncited violation of 10 CFR 73.55(b)(10) for the failure to use the site corrective action program to correct deficiencies in the physical protection program. Specifically, foJJowing an NRC identified violation for the failure to test portal explosive detectors in accordance with the manufacturer s specifications on February I , 2013, the licensee failed to implement adequate corrective actions. Upon notification of the violation, the licensee implemented immediate corrective actions to ensure that the machines would be tested in accordance with site procedures and entered the issue into their corrective action program as CR 2013-12755. The finding is more than minor because it is associated with the access control attribute and adversely affected the security cornerstone objective to provide assurance that the licensee s security system uses a defense in-depth approach and can protect against the design basis threat of radiological sabotage from external and internal threats. It adversely affected the cornerstone objective, because the failure to correct deficiencies involving the testing of explosive detector search equipment could result in the equipment becoming degraded without the licensee s knowledge and could subsequently result in the undetected introduction of explosive material into the protected area.

In addition, this finding has a cross-cutting aspect in the area of Problem Identification and Resolution associated with corrective actions. Specifically, the licensee failed to take appropriate corrective actions for an event which occurred on February 1, 2013, involving the failure to test explosive detectors in accordance with the manufacturer s specifications.

Dynamic Web Site Open: ML14!22A355 (PIM) Failure To Complete Required Searches The inspectors identified a Green non-cited violation of 10 CFR 73.55(h)(3)(i) for failure to accomplish a visual and physical search of personnel before granting access to the protected area. Specifically, the licensee was conducting ao additional visual search of headgear due to as found limitations of the walk-through explosive detectors.

However, the visual search employed was not effective and an additional, more detailed visual and physical search of headgear, or an additional detection equipment search was required to ensure personnel were adequately searched and items clearly identified before granting access to protected areas. For immediate corrective actions to restore compliance, the licensee put an interim visual and physical headgear search in place and briefed the security force on the process. The licensee entered this event into the Fort Calhoun Station corrective action program as CR 2014-03566. The finding is more than minor because it was associated with the Access Control attribute and adversely affected the Safeguards/Security cornerstone objective to provide assurance that the licensee s security system uses a defense-in-depth approach and can protect against the design basis threat of radiological sabotage from external and internal threats. It adversely affected the cornerstone objective because it could have resulted in undetected explosives being allowed into the protected area. The finding is not Greater than Green because no actual introduction of explosives into the protected area occurred. In addition, this finding has a cross-cutting aspect associated with Human Performance, Resources.

For immediate corrective actions the licensee added this issue to the daily pre-shift briefing. Specifically, the shift supervisor will ask the security officers to check to ensure they are carrying the correct size mask before proceeding to on-duty status. The licensee entered this event into the Fort Calhoun Station corrective action program as CR 2014-03600. The finding is more than minor because it was associated with the Response to Contingency Events attribute and adversely affected the Safeguards/Security cornerstone objective to provide assurance that the licensee s security system uses a defense-in-depth approach and can protect against the design basis threat of radiological sabotage from external and internal threats. It adversely affected the cornerstone objective because it could have resulted in the failure of contingency equipment to protect officers as designed. The finding was not Greater than Green because no actual need to utilize the gas mask occurred. In addition, this finding has a cross-cutting aspect associc1;ted with Human Perfonnance, Change Management.

Specifically, the licensee failed to periodically test installed physical security barriers which are a part of the internal plant protective strategy. For immediate corrective actions to restore compliance the licensee successfully tested the security equipment to verify operability and provided the security organization with interim guidance for periodic testing. The licensee entered this event into the Fort Calhoun Station corrective action program as Condition Report CR 2014-03590. The finding is more than minor because, it is associated with the Physical Protection System attribute and adversely affected the Safeguards/Security cornerstone objective to provide assurance that the licensee s security system uses a defense-in-depth approach and can protect against the design basis threat of httn:/lcin<l.nrc.1mv/nrr-office/ms/rlvn/rnn ir1.cfmro9.nrc.vnvl nrr-<1ffice!m.~/rlvn! mn ir J .cfmf()f,/ J7/2() l .5 4:1(): l 7 J>Ml

The licensee entered th is deficiency into their corrective action program for resolution as Condition Reports CR 2013-2863 and 20 12-03796. The team detennined that the failure to make a required Licensee Event Report was a vio lation of 10 CFR 50.73. The violation was evaluated using Section 2.2.4 of the NRC Enforcement Policy because the failure to submit a required licensee event report may impact the ability of the NRC to perform its regulatory oversight function. As a result, this violation was evaluated using traditional enforcement. In accordance with Section 6.9 of the NRC Enforcement Policy, this violation was determined to be a Severity Level IV non-cited violation. The team determined that a cross-cutting as pect was not applicable to this performance deficiency because the failure to make a required report was strictly associated with a traditional enforcement violation.

Open: MLl4128A3l4 (PIM) Failure to Make Required 10 CFR 50.46 Report Within Required Time (Section 40A3.2)

A Severity Level IV non-cited violation of IO CFR 50.46, Acceptance criteria for emergency core cooling systems (ECCS) for light-water nuclear power reactors, was identified involving the failure to submit a report within 30 days of discovery of a significant change in the application of the ECCS model that affected the peak cladding temperature. The licensee submitted the required IOCFR 50.46 report late on September 20, 2013 (ML13266A108).

This report was subsequently reviewed by the NRC staff date October 2, 20 13, and detennined to be acceptable. The NRC staff determ ined that while the configuration change to the HPSl system resulted in a higher peak cladding temperature, it is within the regulatory requirements of 10 CFR 50.46(b)(I). The licensee initiated CRs-20 14-00674 and 2014-01356 to address issuance of the late report. This performance deficiency was determined to be subject to traditional enforcement because it impeded the regulatory process, in that the failure to submit a timely report of significant ECCS analytical changes prevented the NRC technical staff from independently evaluating the potential safety implications ofreductions in safety injection flow into the reactor during an accident. This violation was determined to be a Severity Level IV violation because it is consistent with the examples in Paragraph 6.9.d of the NRC Enforcement Policy. Because this violation is subject to traditional enforcement, no cross-cutting aspects have been assigned. (Section 40A3.2).

Dynamic Web Site Open: ML14115A411 (PIM) Failure to Obtain Prior NRC Approval for a Change in Method of Evaluation The team identified three examples of a non-cited violation of 10 CFR 50.59, Changes, Test, and Experiments, associated with the licensee s failure to adequately evaJuate changes to detennine if prior NRC approval is required.

Specifically, from April 19, 2011, through August 17, 2012, the licensee failed to obtain a license amendment pursuant to Section 50.90 prior to implementing a proposed change, test, or experiment if the change, test, or experiment would result in a departure from a method of evaluation described in the Updated Safety Analysis Report.

The licensee addressed these issues by submitting a license amendment which was reviewed and approved by the NRC. This issue has been entered into the licensee s corrective action program as Condition Reports CR 2013-03839, 2013-04266, 2013-05210, 2013-14363, and 2013-14665. The licensee s failure to implement the requirements of 10 CFR 50.59 and adequately evaluate changes to requirements for tornado missjJe protection described in the Updated Safety Analysis Report was a performance deficiency. Because this performance deficiency had the potential to impact the NRC s ability to perform its regulatory function, the team evaluated the performance deficiency using traditional enforcement. In accordance with Section 2.1.3.E.6 of the NRC Enforcement Manual, the team evaluated this finding using the significance detennination process to assess its significance. Using Inspection Manual Chapter 0609, Appendix A, The Significance Determination Process for Findings At-Power, the finding was determined to have very low safety significance (Green) because it: (1) was not a deficiency affecting the design or 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 Joss 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; (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 licensee s maintenance rule program; and (5) did not involve the loss or degradation of equipment or function specifically designed to mitigate a seismic, flooding, or severe weather event. Therefore, in accordance with Section 6.1.d.2 of the NRC Enforcement Policy, the team characterized this performance deficiency as a Severity Level lY violation. The team determined that a cross-cutting aspect was not applicable to this performance deficiency because the failure to adequately evaluate changes in accordance with 10 CFR 50.59 was strictly associated with a traditional enforcement violation.

Specifically, the licensee failed to update station calculations to incorporate actual test data for sluice gate leakage to ensure design basis flood levels do not adversely affect equipment important to safety. The licensee entered this issue into its corrective action program as Condition Report 2014-09156 and initiated actions to update station calculations. This finding was more than minor, and therefore a finding, because if left uncorrected, the fmding would have the potential to lead to a more significant safety concern. Specifically, failure to complete accurate calculations that support engineering modifications for mitigating the consequences of an external flooding event could lead to unanalyzed conditions adversely affecting safety related systems or components. The NRC performed an initial screening of the finding in accordance with NRC Manual Chapter IMC 0609, Appendix A, The Significance Determination Process (SDP) for Findings At-Power.

Specjfically, the licensee failed to take effective corrective action to establish an appropriate monitoring :frequency, which took into account variable environmental conditions to mitigate potential common mode failure of raw water 4160 V motor cables in underground ducts and manholes identified during the Component Design Basis Inspection performed in 2009. The violation is being cited because the licensee had failed to restore compliance in a reasonable period foJlowing documentation of the issue as a non-cited violation issued December 30, 2009. The failure to take effective corrective action to ensure the reliability and capability of the safety-related cables powering tbe raw water pump motors was a perfonnance deficiency. Furthermore, the finding was within the licensee's ability to foresee and correct because the licensee had multip]e opportunities to correct the continuing challenge to the safety~related cables and raceways for the raw water system over an extended period. The finding was more than minor because it adversely affected the Mitigating Systems Cornerstone attribute of design control for ensuring the availability, reliability, and capability of systems that respond to Initiating Events to prevent undesirable consequences. The finding is of very low safety significance because it was a design deficiency that did not result in loss of operability or functionality. This finding has a crosscutting aspect in the decision-making program component of the human performance area because the licensee failed to use conservative assumptions in decision-making and 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.

Open: ML1210JA193 Discussed: MLl4094A052 (PIM) Failure to Ensure that the 480 Vac Electrical Power Distribution System Design Requirements were Implemented and Maintained The failure to ensure that the 480 Vac electrical power distribution system design requirements were properly implemented and maintained through proper maintenance, modification, and design activities led to a catastrophic fire in a switchgear impacting the required safe shutdown capability of the plant. Three self-revealing apparent violations were identified with this perfonnance deficiency: A violation of 10 CFR Part 50, Appendix B, Criterion lll, Design Control, for the failure to ensure that design changes were subject to design control measures commensurate with those applied to the original design and that measures were established to assure that applicable regulatory requirements and the design basis for those safety-related structures, systems, and components were correctly translated into specifications, drawings, procedures, and instructions; A violation of 10 CFR Part 50, Appendix B, Criterion XVI Corrective Action, for the failure to establish measures to assure that a significant condition adverse to quality was promptly identified and corrected, and measures taken to preclude repetition; A violation of License Condition 3.D, Fire Protection Program, for the failure to ensure that the electrical protection and physical design of the 480 Vac electrical power distribution system provided the electrical bus separation required by the fire protection program. Specifically: (1) design reviews and work planning for a modification to install twelve new 480 Vac load center breakers failed to ensure that the cradle adapter assemblies had a low-resistance connection with the switchgear bus bars by establishing a proper fit and requiring low resistance connections; (2) preventive maintenance activities were inadequate to ensure proper cleaning of conductors, proper torquing of bolted conductor and bus bar connections, or adequate inspection for abnormal connection temperatures; and (3) design reviews of the electrical protection and train separation of the 480 Vac electrical power distribution system were inadequate to ensure that a fire in load center l B4A would not adversely impact operation of redundant safe shutdown equipment in load center IB3A, as required by the fire protection program. The licensee entered these issues into their corrective action progrtlJJl under numerous condition report numbers, which are described in the body of this report. The performance deficiency was determined to be more than minor because it affected the Initiating Events Cornerstone and was associated with both the protection against external events attribute (i.e., fire) and the design control attribute. The finding affected the cornerstone objective of limiting the likelihood of those events that upset plant stability and challenge critical safety functions during shutdown as well as power operations. Manual Chapter 0609.04, Phase I Initial Screening and Characterization of Findings, Table 4a, directed the process to a Phase 3 analysis because the finding increased the likelihood of an external event (fire), and impacted mitigating systems needed to respond to that initiating event. A Phase 3 analysis was completed using the plant-specific Standardized Plant Analysis Risk Model for Fort Calhoun, Revision 8.15, the Individual Plant Evaluation of External Events (IPEEE), and hand calculations. The analysis covered the risk affected by the performance deficiency for postulated fires of any of the remaining nine continuously energized breakers including the potential for multiple fire initiators. Additionally, seismically-induced fires were postulated based on the characteristics of the performance deficiency. Based in the best available information the performance deficiency was preliminarily characterized as a finding of high safety significance (Red). This performance deficiency had a crosscutting aspect in the area of human performance associated with the resources component because the licensee did not ensure that personnel, equipment, procedures, and other resources were adequate to assure nuclear safety. Specifically, the licensee did not ensure that design documentation, procedures, and work packages were adequate to assure that design margins were maintained.

Open: ML13197A26 l Discussed: ML I5071 Al 15 (PIM) Failure to Promptly Identify and Correct a Condition Adverse to Quality (Initial Entry) The team identified a violation of 10 CFR Part 50, Appendix B, Criterion XVI, Corrective Actions, associated with the licensee s failure to promptly identify and correct a condition adverse to quality. Specifically, from l 991 to present, the licensee failed to properly evaluate a 4160 Vac/480 Vac transformer fault or a 480 Vac load center bus fault and the potential effect on system operability. This issue has been entered into the corrective action program as Condition Report CR 2013--05631. This finding is related to the Red finding issued on April 10, 2012, regarding a significant internal fire event in the 480 Vac safety-related switchgear. The performance deficiency is more than minor, and therefore a finding, because it was associated with both the design control and protection against external factors attribute of the Mitigating Systems Cornerstone, and affected the associated cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. The significance of this finding is bounded by the significance of a related Red finding regarding a fire in the 480 Vac safety-related switchgear in June 20 I 1 (NRC Inspection Report 05000285/2012010).

The team determined that although the performance deficiency occurred in 1991, this finding is indicative of current plant performance because the performance characteristic has not been corrected or eliminated. Specifically, the licensee continued to display the same behaviors with regard to decision-making. Therefore, this finding has a cross-cutting aspect in the area of human performance associated with the decision-making component because the licensee failed to use conservative assumptions in decision-making and adopt a requirement to demonstrate that the proposed action is safe in order to proceed rather than a requirement to demonstrate it is unsafe in order to disapprove the action. (IR# 05000285/2013008 dated July 16, 2013) (Update and Closure)The inspection team reviewed the licensee s corrective actions to address VIO 05000285/2013008-14, Failure to Promptly Identify and Correct a Condition Adverse to Quality, involving a breaker/fuse coordination study and potential vulnerabilities of the 4160-volt and 480-voJt e]ectrica] distribution systems.

Open: MLl41 l5A411 (PIM) Failure to Ensure Tornado MissjJe Protection for Site Components The team identified multiple examples of a violation of 10 CFR 50, Appendix B, Criterion III, Design Control, involving the failure to establish applicable tornado missile protection design requirements for components needed to ensure the capability to shut down the reactor and maintain it in a safe shutdown condition. Specific examples included the steam driven auxiliary feedwater pump exhaust stack, auxiliary feedwater components located in Room 81, raw water pump electrical pull boxes PB-128T and PB-I 29T, and diesel generator fuel oil storage tank fill and vent lines. The licensee implemented plant modifications to adequately protect all affected equipment from tornado generated missiles and entered the deficiencies into its corrective action program for resolution as Condition Reports CR 2013-03839, 2013-03842, 2013-14117, and 2013-14246. The failure to ensure that station components were adequately protected from tornado missiles was a performance deficiency. ln accordance with NRC Inspection Manual Chapter 0612, Appendix B, Issue Screenjng, the performance deficjency was detcnnined to be more than minor, and therefore a finding, because it was associated with the design control attribute of the Mitigating Systems Cornerstone, and affected the associated cornerstone objective to ensure availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, the finding affected the reliability of required components following a postulated tornado-generated missile impact. The team evaluated the finding using lnspection Manual Chapter (IMC) 0609, Appendix A, The Significance Detennination Process (SDP) for Findings at Power, Exhibit 4, External Events Screening Questions. The finding required a detailed risk evaluation because it involved the lack of equipment specifically designed to mitigate a severe weather initiating event (tornado) and could have degraded two or more trains of a multi-train system. The Region 1V senior reactor analyst performed a detailed risk evaluation in accordance with Appendix A, Section 6.0, Detailed Risk Evaluation. The NRC concluded the finding was characterized as having low to moderate safety significance (White). The calculated change in core damage frequency of 2.6 x 10-6 was dominated by a tornado-induced non-recoverable loss of offsite power with the failure of the emergency power supply system. The analyst determined that the finding did not affect the internal events initiator risk and would not involve a significant increase in the risk of a large early release ofradiation. The finding has a cross-cutting aspect in the area of problem identification and resolution associated with the corrective action program component because the licensee failed to thoroughly evaluate problems such that the resolutions address the causes. The NRC has concluded that the infonnation regarding the reason for the violation, the corrective actions implemented to correct the violation and prevent recurrence, and the date when full compliance was achieved was obtained by the NRC during our inspection activities. Therefore, the licensee is not required to respond to this letter unless the description contained in the enclosed report does not accurately reflect corrective actions or the licensee's position. Additionally, since this issue was identified and resolved by the station during the extended shutdown, under increased NRC oversight of the Inspection Manual Chapter 0350 Process, this issue will not be used for future plant performance assessment inputs and is considered closed.

Dynamic Web Site (Initial Entry) A cited violation of 10 CFR Part 50, Appendix B, Criterion lll, Design Control, was identified involving the failure to assure that applicable regulatory requirements and design bases were correctly translated into specifications, drawings, procedures, and instructions. Specifically, the licensee failed to properly evaluate NRC Bulletin 88-04, Potential Safety-Related Pump Loss, for strong pump weak pump interaction regarding auxiliary fecdwater pumps FW-6 and FW-10. The evaluation failed to consider pump-to-pump interaction that may result due to pump discharge check valve leakage. In addition, the licensee failed to re-evaluate the condition after surveillance testing performed on November 28, 2010, and September 1, 2012, identified leakage past both pump discharge check valves. The licensee entered this issue into its corrective action program as Condition Report 2014-08381 and initiated actions to re-evaluate NRC Bulletin 88-04. This performance deficiency was more than minor, and therefore a finding, because it was associated with the equipment attribute of the Mitigating Systems Cornerstone, and affected the associated cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. The NRC performed an initial screening of the finding in accordance with NRC Manual Chapter IMC 0609, Appendix A, The Significance Determination Process (SDP) for Findings At-Power. Using IMC 0609, Appendix A, Exhibit 2, Mitigating Systems Screening Questions, dated July l ,

2012, the finding was of very low safety significance (Green) because it: (1) was not a deficiency affecting the design or 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 non-technical specification trains of equipment designated as high safety-significant in accordance with the licensees maintenance rule program. This finding has a cross-cutting aspect in the area of human performance because the licensee failed to demonstrate a conservative bias in decision making-practices.

Specifically, the licensees etermination that the event is not credible failed to consider documented check valve leakage in the auxiliary feedwater system. (IR# 05000285/2014009 dated September 18, 2014) (Update and Closure)

Specifically, from initial construction through October 2013, the licensee failed to fully incorporate applicable design requirements for components needed to ensure the capability to shut down the reactor and maintain it in a safe shutdown condition following a high energy line break. The licensee addressed this deficiency by reconstituting the design analysis associated with the high energy line break and environmental qualification programs, receiving a change to the facilities licensing basis, and implementing plant modifications. This issue was entered into the licensee s corrective action program as Condition Report CR 2013-2857. The failure to ensure that design requirements were correctly translated into installed plant equipment was a performance deficiency. This performance deficiency was more than minor, and therefore a finding, because it is associated with the equipment performance attribute of the Mitigating Systems Cornerstone and affected the associated objective to ensure availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, the licensee s failure to translate the design requirements into installed plant equipment resulted in a condition where structures, systems, and components necessary to mitigate the effects of a high energy line break may not have functioned as required.

Dynamic Web Site Determination Process (SDP) for Findings At-Power, dated June 19, 2012, and determined that this finding required a detailed risk evaluation because it was a deficiency affecting the design and qualification of a mitigating structure, system, or component that resulted in a loss of operability or functionality and represented a loss of system and/or function. The Region IV senior reactor analyst performed a detailed risk evaluation in accordance with Appendix A, Section 6.0, Detailed Risk Evaluation. The detailed risk evaluation concluded the finding was best characterized as having low to moderate safety significance (White). The minimum calculated change in core damage frequency of 4.1 x 10-6 was dominated by a reactor coolant pump seal cooler loss of coolant accident followed by the failure of four containment isolation valves that were not properly qualified for a harsh environment. The upper bound was shown quantitatively and/or qualitatively to be less than 1.0 x 10-5. The analyst determined that the finding did not affect the external events initiator risk and would not involve a significant increase in the risk of a large early release of radiation. The team determined that this finding does not have a cross-cutting aspect because the most significant contributor of this finding would have occurred more than three years ago, and therefore, does not reflect current licensee performance.

Specifically, the licensee failed to restore compliance following NRC identification of the licensee s failure to correct a runout condition of the containment spray system (CS) documented in NCV 05000285/2008003-05, in August 2008. Licensee corrective actions to correct the issue included completion of an analysis of containment spray pump operation during the main steam line break (MSLB) event; revision of CS design documentation; analysis of motor perfom1ance by an electrical vendor; and completion of a temporary modification to throttle the CS pump discharge valves to provide additional system resistance preventing pump runout. Future corrective actions include a permanent design change to prevent CS pump runout. The licensee initiated CR 2014-02242 on February 19, 2014, to document this failure to restore compJfance. This fmd1ng was more than minor because it adversely impacted the Barrier Integrity cornerstone objective to provide reasonable assurance that physical design barriers (containment) protect the public from radionuclide releases caused by accidents or events. The inspectors reviewed NRC IMC 0609, Attachment 4, Initial Characterization of Findings , Table 3 SDP Appendix Router. While this issue was identified during a refueling outage, the inspectors determined that the majority of the exposure time for this violation occurred with the reactor at power and should be evaluated using the Significance Determination Process in accordance with IMC 0609, The Significance Determination Process (SOP) for Findings at-Power, Appendix A, Exhibit 3, Barrier Integrity Screening Questions. The inspectors detennined that the finding did not represent an actual open pathway in containment or containment isolation logic, nor did the finding represent an actual reduction in the function of containment hydrogen igniters. Based on the guidance in the Exhibit 3 checklist the inspectors determined that the finding was of very low safety significance. The inspectors detennined that the finding had a cross-cutting aspect of avoiding complacency in the human performance area, because the licensee s staff failed to recognize latent issues even while expecting successful outcomes. (IR# 05000285/2014002 dated March 19, 2014) (Update and Closure)

Specifically, the licensee established an Alert low river level emergency classification criteria that was below the raw water pump s mirumum suction requirements, contrary to the standard emergency action level scheme. The licensee entered this issue into its corrective action program as Condition Report 2014-08757 which included actions to re-evaluate the capability of the raw water pumps to operate at low river levels. This finding was more than minor, and therefore a finding, because it was associated with the emergency response organization performance attribute of the Emergency Preparedness Cornerstone and affected the associated cornerstone objective to ensure that the licensee is capable of implementing adequate measures to protect the health and safety of the public in the event of a radiological emergency. Specifically, inaccurate emergency actions levels degrade the licensee s ability to implement adequate measures to protect public health and safety. The finding was evaluated using the Emergency Preparedness Significance Determination Process, and was determined to be of very ]ow safety significance (Green) because the finding was not a lost or degraded risk significant planning function. The planning standard function was not degraded because the emergency classifications would have been declared although potentially in a delayed manner. This finding has a cross-cutting aspect in the area of human performance in that the licensee did not ensure that personnel, equipment, procedures and other resources are available and adequate to support nuclear safety.

(PIM) Failure to Correct SGI Control Deficiencies An apparent violation of 10 CFR 73.55{b)(l0) was identified involving two examples where the licensee corrective action program failed to correct deficiencies associated with the physical protection program. Specifically, following identification of uncontrolled SGI on May 24, 2011, the licensee failed to identify that tapes used by the site to backup system on both the local area network (LAN) and STELLANT database systems contained the SGl information, and these backup tapes were not properly controlled for storage of the SGl information. Additionally, the NRC identified that the licensee s method for purging the electronic SGI from the STELLANT database was inappropriate and therefore failed to adequately remove the SGI from the tapes. The licensee entered these issues into their corrective action program as CR 2011-7700 and 2011-7849. The finding is more than minor because jf left uncorrected it could become a more significant safety concern. Specifically, the failure to correct SGI storage and control deficiencies increases the vulnerability of the information to be subject to unauthorized disclosure. The finding was assessed using Physical Protection Significance Determination Process (PPSDP) described in IMC 0609, Appendix E, Figure 3, and was preliminarily determined to be of low to moderate security significance (White). The finding had a crosscutting aspect in the area of problem identification and resolution related to corrective actions.

Specifically, after the licensee identified improperly controlled safeguards information they failed to implement appropriate corrective actions to control the information [P l.d].

The licensee s evaluation and corrective actions were documented in their corrective action program as CR 201 l 0299. The finding is more than minor because if left uncorrected, the failure to protect SGI increases its likelihood of compromise and the potential for its disclosure to unauthorized individuals. The finding was assessed using Physical Protection Significance Determination Process (PPSDP) described in IMC 0609, Appendix E, Figure 3, and was preliminarily determined to be of low to moderate security significance (White). In addition, the finding had a crosscutting aspect in the area of problem identification and resolution associated with problem evaluation. Specifically, the licensee failed to thoroughly evaluate a previous loss of control of SGI event such that resolutions effectively addressed the causes and the extent of conditions that lead to this event [P J.c]

Specifically, from November 29, 2011, to June 25, 2012, the licensee failed to properly evaluate equipment used to reproduce Safeguards Information to ensure that unauthorized individuals could not access Safeguards Information on the equipment. The licensee implemented immediate compensatory measures and entered the issue into the site corrective action program as Condition Report CR 2012-05931. This fmding and its corrective actions will be managed by the NRC s Inspection Manual Chapter 0350 Oversight Panel. The finding is more than minor because if left uncorrected it could become a more significant safety concern. Specifically, the failure to adequately protect SGI increases its likelihood of compromise and the potential for its disclosure to unauthorized individuals. The significance of this finding is bounded by the significance of the White violations documented in Inspection Report 05000285/2011406. In addition, the finding has a cross-cutting aspect in the decision-making component, conservative assumptions aspect, because the licensee failed to identify the possible unintended consequences of not ensuring the plotter did not have a hard drive.

Dynamic Web Site Information, and an associated reactor oversight program finding (NCV 05000285/2013013-J 9, Failure to Translate Appendix R License Exemptions into the Plants Fire ProtJection Program Design ), for the licensee s failure to provide information to the Commission that ~as complete and accurate in a)) material respects.

Specifically, when responding to a request for additional information, the licensee supplied incorrect information to the NRC and this information was subsequently used by the NRC to support a license amendment for the station.

  • This issue was entered into the station s corrective action program as Condition Report CR 2013-15021. The failure to provide the NRC with complete and accurate information when responding to a request for additional information was a performance deficiency. Using Inspection Manual Chapter 0612, Appendix B, Issue Screening, Figure 1, dated September 7, 2012, the team determined that the failure to provide complete and accurate information was a performance deficiency that required evaluation under both traditional enforcement and the reactor oversight program. The performance deficiency was determined to be more than minor because: (1) the information was considered material to the NRC s decision making process; and (2) it affected the equipment performance attribute of the Mitigating Systems Cornerstone with regard to availability, reliability, and capability of the raw water pumps to perform their safety function during a fire in the intake structure. Using Inspection Manual Chapter 0609, Appendix F, Fire Protection Significance Determination Process, the team detennined the finding to have very low safety significance (Green) because it only affected the ability to reach and maintain cold shutdown conditions.

Under the traditional enforcement review, the team determined that in accordance with Section 6.9.c.1 of the NRC Enforcement Policy, this finding represented a Severity Level III violation. Specifically, the team determined that if this information had been completely and accurately provided, it would likely have caused the NRC to undertake a substantial further inquiry. The NRC takes the issue of complete and accurate license submHtals very seriously. For this reason, the NRC considered citing this as a Severity Level III violation, as discussed in the Enforcement Policy, as the NRC had approved a licensing action based on the incorrect information. However, after consideration by NRC management, and with the approval of the Director of the Office of Enforcement, it was determined that a Severity Level IV, cited violation was appropriate. This decision was based on the very low safety significance (Green) of the associated reactor oversight program finding (05000285/2013013~19). There was no cross-cutting aspect assigned to this finding because the inaccurate information was provided over three years ago and this issue does not reflect present licensee performance. (IR# 05000285/2013013 dated April 3, 2014) (Update and Closure)

The team reviewed the licensee s corrective actions to address deficiencies related to VIO 05000285/2013013-20, Failure to Provide Complete and Accurate Information to the NRC. The licensee s corrective actions are documented in a letter to the NRC, dated October 8, 2013 (ML13282A557). Specifically, the letter documents that inaccurate information was provided to the NRC and clarifies the inaccurate information. The team reviewed these corrective actions and determined them to be adequate to correct the deficiency; therefore, VlO 05000285/2013013-20 is closed. (IR# 05000285/2015008 dated March 12, 2015)

Open: ML14128A314 Discussed: ML14318A886 (PIM) Untimely Submittal of Required Licensee Event Reports Two examples of a cited Severity Level IV violation of 10 CFR 50.73, Immediate Notification Requirements for Operating Nuclear Power Reactors, were identified involving the failure to submit a required licensee event report (LER) within 60 days following discovery of an event requiring a report. In the first example, LER 2013-010-0 was submitted on July 2, 2013, seventy-nine days after the flow imbalance was observed by the licensee s staff. In the second example, LER 2013-017-0 was submitted to the NRC on December 27, 2013, 62 days after the event date on the licensee s reportability evaluation and sixty-six days after a condition report documented the reportable condition. The licensee initiated CR 2014-01358 on January 29, 2014 to document this repetitive violation. The violation was evaluated using Section 2.2.4 of the NRC Enforcement Policy, because the failure to submit a required LER may impact the ability of the NRC to perfonn its regulatory ov,ersight function. As a result, this violation was evaluated using traditional enforcement In accordance with Section 6.9(d)(9) of the NRC Enforcement Policy, this violation was determined to be a Severity Level IV violatfon. Tbe inspetors determined that a cross-cutting aspect was not applicable to this performance deficiency because the failure to make a required report was strictly associated with a traditional enforcement violation.

Open: ML14318A886 (PIM) Failure to Perform Evaluation for Design Change A cited violation of 10 CFR 50.59, Changes, Tests, and Experiments, was identified involving the failure to evaluate if a change to the facility as described in the Updated Safety Analysis Report would require prior NRC review and approval. Specifically, the licensee did not evaluate a change that would permanently substitute a manual action for an automatic action to add water and nitrogen gas to the component cooling water surge tank. The licensee entered this issue into its corrective action program as Condition Report 2014-09080 and initiated action to evaluate the change to the component cooling water system. The NRC determined that the licensees failure to perfonn an evaluation prior to implementing a proposed change described in the Updated Safety Analysis Report was a violation of 10 CFR 50.59. Because this performance deficiency had the potential to impact the NRCs ability to perform its regulato.r y function, the NRC evaluated the performance deficiency using traditional enforcement. In accordance with Section 2.1.3.E.6 of the NRC Enforcement Manual, the team evaluated this finding using the significance determination process to assess its significance. The NRC performed an initial screening of the finding in accordance with NRC Manual Chapter IMC 0609, Appendix A, The Significance Determination Process (SOP) for Findings At-Power. Using IMC 0609, Appendix A, Exhibit 2, Mitigating Systems Screening Questions, dated July 1, 2012, the finding was of very low safety significance (Green) because it: (I) was not a deficiency affecting the design or qualification of a mitigating structure, system, or component, and did not result in a loss of operability or fW1ctionality; (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 non-technical specification trains of equipment designated as high safety~significant in accordance with the licensee s maintenance rule program. Therefore, in accordance with Section 6.1.d.2 of the NRC Enforcement Policy this performance deficiency is being characterized as a Severity Level IV violation. The team determined that a cross-cutting aspect was not applicable to this finding because the issue was strictly associated with a traditional enforcement violation.
