SUMMARY OF FINDINGS

Inspection Report 05000331/2012004, 07/01/2012 - 09/30/2012; Duane Arnold Energy Center;

Maintenance Effectiveness.

This report covers a three-month period of inspection by resident inspectors and announced baseline inspections by regional inspectors. One Green finding was identified by the inspectors.

The finding was considered an NCV of NRC regulations. The significance of most findings is indicated by their color (Green, White, Yellow, Red) using Inspection Manual Chapter (IMC) 0609, Significance Determination Process (SDP). Findings for which the SDP does not apply may be Green or be assigned a severity level after NRC management review. The NRCs program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG-1649, Reactor Oversight Process, Revision 4, dated December 2006.

NRC-Identified

and Self-Revealed Findings

Cornerstone: Mitigating Systems

Green.

A finding of very low safety significance and associated non-cited violation (NCV) of Technical Specification (TS) 5.4.1.d, Fire Protection Program Implementation, was self-revealed on June 24, 2012, for the failure of the licensee to test the diesel fire pump in accordance with established procedures recommended by the equipment manufacturer. Specifically, licensee surveillance test procedure (STP) NS13B015,

Diesel Driven Fire Pump Periodic Pump Run, did not ensure the coolant tank was completely filled with water prior to operation as recommended in the equipment manufacturers operation and maintenance manual; leading to the diesel fire pump overheating and being declared non-functional. Corrective actions by the licensee included replacing the degraded coolant reservoir tank and revising applicable procedures to implement the recommendations by the equipment manufacturer.

The inspectors determined that failing to test the diesel fire pump in accordance with established procedures recommended by the equipment manufacturer was a performance deficiency because it was the failure to meet a TS requirement, and the cause was reasonably within the licensees ability to foresee and prevent and should have been corrected. The performance deficiency was determined to be more than minor and a finding because it was associated with the Protection Against External Factors (Fire) attribute of the Mitigating Systems Cornerstone, and adversely affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. An NRC regional Senior Risk Analyst determined the finding was of very low safety significance (Green).

The inspectors determined that the contributing cause that provided the most insight into the performance deficiency was associated with the cross-cutting aspect of Problem Identification and Resolution, having Corrective Action Program components, and involving the licensee taking appropriate corrective actions to address safety issues and adverse trends in a timely manner commensurate with their safety significance and complexity. P.1(d) (Section 1R12)

Licensee-Identified Violations

A violation of very low safety significance that was identified by the licensee was reviewed by inspectors. Corrective actions planned or taken by the licensee were entered into the licensees corrective action program. The violation and corrective action tracking number is listed in Section 4OA7 of this report.

REPORT DETAILS

Summary of Plant Status

REACTOR SAFETY

Cornerstones: Initiating Events, Mitigating Systems, and Barrier Integrity

1R01 Adverse Weather Protection

.1 Summer Seasonal Readiness Preparations

a. Inspection Scope

The inspectors performed a review of the licensees preparations for summer weather for selected systems, including conditions that could lead to an extended drought.

During the inspection, the inspectors focused on plant specific design features and the licensees procedures used to mitigate or respond to adverse weather conditions.

Additionally, the inspectors reviewed the Updated Final Safety Analysis Report (UFSAR)and performance requirements for systems selected for inspection, and verified that operator actions were appropriate as specified by plant specific procedures. Specific documents reviewed during this inspection are listed in the Attachment to this report.

The inspectors also reviewed corrective action program (CAP) items to verify that the licensee was identifying adverse weather issues at an appropriate threshold and entering them into the CAP in accordance with station corrective action procedures.

The inspectors reviews focused specifically on the following plant systems:

This inspection constituted one seasonal adverse weather sample as defined in Inspection Procedure (IP) 71111.01-05.

b. Findings

No findings were identified.

.2 External Flooding

a. Inspection Scope

The inspectors evaluated the design, material condition, and procedures for coping with the design basis probable maximum flood. The evaluation included a review to check for deviations from the descriptions provided in the UFSAR for features intended to mitigate the potential for flooding from external factors. As part of this evaluation, the inspectors checked for obstructions that could prevent draining, checked that the roofs did not contain obvious loose items that could clog drains in the event of heavy precipitation, and determined that barriers required to mitigate the flood were in place and operable. Additionally, the inspectors performed a walkdown of the protected area to identify any modification to the site which would inhibit site drainage during a probable maximum precipitation event or allow water ingress past a barrier. The inspectors also walked down underground bunkers/manholes subject to flooding that contained multiple train or multiple function risk-significant cables. The inspectors also reviewed the abnormal operating procedures (AOPs) for mitigating the design basis flood to ensure the procedures could be implemented as written.

The inspectors performed this sample as a part of TI-2515/187, which is documented in Section 4OA5.

This inspection constituted one external flooding sample as defined in IP 71111.01-05.

b. Findings

No findings were identified.

.3 Readiness For Imminent Adverse Weather Condition - Extreme Heat/Drought

Conditions

a. Inspection Scope

The inspectors performed a detailed review of the licensees procedures and preparations for operating the facility during an extended period of time when ambient outside temperature was high and the ultimate heat sink was experiencing elevated temperatures and below average levels. The inspectors focused on plant specific design features and implementation of the procedures for responding to or mitigating the effects of these conditions on the operation of the facility. Inspection activities included a review of the licensees adverse weather procedures, daily monitoring of the off-normal environmental conditions, and that operator actions specified by plant specific procedures were appropriate to ensure operability of the facilitys normal and emergency cooling systems. Documents reviewed are listed in the Attachment to this report.

This inspection constituted one readiness for imminent adverse weather condition sample as defined in IP 71111.01-05.

b. Findings

No findings were identified.

1R04 Equipment Alignment

.1 Quarterly Partial System Walkdowns

a. Inspection Scope

The inspectors performed partial system walkdowns of the following risk-significant systems:

  • 4160V/480V Essential Electrical Distribution and Switchyard during Abnormal Electrical Lineup for Breaker Maintenance and Inspection; and

The inspectors selected these systems based on their risk significance relative to the Reactor Safety Cornerstones at the time they were inspected. The inspectors attempted to identify any discrepancies that could impact the function of the systems and, therefore, potentially increase risk. The inspectors reviewed applicable operating procedures, system diagrams, the UFSAR, TS requirements, outstanding work orders (WOs), condition reports (CRs), and the impact of ongoing work activities on redundant trains of equipment in order to identify conditions that could have rendered the systems incapable of performing their intended functions. The inspectors also walked down accessible portions of the systems to verify system components and support equipment were aligned correctly and operable. The inspectors examined the material condition of the components and observed operating parameters of equipment to verify that there were no obvious deficiencies. The inspectors also verified that the licensee had properly identified and resolved equipment alignment problems that could cause initiating events or impact the capability of mitigating systems or barriers and entered them into the CAP with the appropriate significance characterization. Documents reviewed are listed in the to this report.

These activities constituted three partial system walkdown samples as defined in IP 71111.04-05.

b. Findings

No findings were identified.

1R05 Fire Protection

.1 Routine Resident Inspector Tours

a. Inspection Scope

The inspectors conducted fire protection walkdowns which were focused on availability, accessibility, and the condition of firefighting equipment in the following risk-significant plant areas:

  • Area Fire Plan (AFP)-01; Torus Area and North Corner Rooms Elevation 716-9 and 735-7 1/2;
  • AFP-26; Control Building Control Room Complex;
  • AFP-27; Control Building Control Room HVAC Room;
  • AFP-16; Condensate Pump Area; and

The inspectors reviewed areas to assess if the licensee had implemented a fire protection program that adequately controlled combustibles and ignition sources within the plant, effectively maintained fire detection and suppression capability, maintained passive fire protection features in good material condition, and implemented adequate compensatory measures for out-of-service, degraded or non-functional fire protection equipment, systems, or features in accordance with the licensees fire plan.

The inspectors selected fire areas based on their overall contribution to internal fire risk as documented in the licensees Individual Plant Examination of External Events with later additional insights, their potential to impact equipment which could initiate or mitigate a plant transient, or their impact on the licensees ability to respond to a security event. Using the documents listed in the Attachment to this report, the inspectors verified that fire hoses and extinguishers were in their designated locations and available for immediate use; that fire detectors and sprinklers were unobstructed; that transient material loading was within the analyzed limits; and, that fire doors, dampers, and penetration seals appeared to be in satisfactory condition. The inspectors also verified that issues identified during the inspection were entered into the licensees CAP.

Documents reviewed are listed in the Attachment to this report.

These activities constituted five quarterly fire protection inspection samples as defined in IP 71111.05-05.

b. Findings

No findings were identified.

.2 Annual Fire Protection Drill Observation

a. Inspection Scope

On September 11, 2012, the inspectors observed a fire brigade activation following a declaration of a fire outside of the mechanical maintenance shop. Based on this observation, the inspectors evaluated the readiness of the plant fire brigade to fight fires.

The inspectors verified that the licensee staff identified deficiencies; openly discussed them in a self-critical manner at the drill debrief, and took appropriate corrective actions.

Specific attributes evaluated were:

  • proper wearing of turnout gear and self-contained breathing apparatus;
  • proper use and layout of fire hoses;
  • employment of appropriate fire fighting techniques;
  • sufficient firefighting equipment brought to the scene;
  • effectiveness of fire brigade leader communications, command, and control;
  • search for victims and propagation of the fire into other plant areas;
  • smoke removal operations;
  • utilization of pre-planned strategies;
  • adherence to the pre-planned drill scenario; and
  • drill objectives.

Documents reviewed are listed in the Attachment to this report.

These activities constituted one annual fire protection inspection sample as defined in IP 71111.05-05.

b. Findings

No findings were identified.

1R06 Flooding

.1 Internal Flooding

a. Inspection Scope

The inspectors reviewed selected risk important plant design features and licensee procedures intended to protect the plant and its safety-related equipment from internal flooding events. The inspectors reviewed flood analyses and design documents, including the UFSAR, engineering calculations, and AOPs to identify licensee commitments. In addition, the inspectors reviewed licensee drawings to identify areas and equipment that may be affected by internal flooding caused by the failure or misalignment of nearby sources of water, such as the fire suppression system. The inspectors also reviewed the licensees corrective action documents with respect to past flood-related items identified in the CAP to verify the adequacy of the corrective actions.

The inspectors performed a walkdown of the following plant area to assess the adequacy of watertight doors and verify drains and sumps were clear of debris and were operable, and that the licensee complied with its commitments:

  • Torus Room and Low Level Radioactive Waste Areas during Torus Water Temporary Storage Vault Modification.

Specific documents reviewed during this inspection are listed in the Attachment to this report.

This inspection constituted one internal flooding sample as defined in IP 71111.06-05.

b. Findings

No findings were identified.

.2 Underground Cable Vaults

a. Inspection Scope

The inspectors selected underground bunkers/manholes subject to flooding that contained cables whose failure could disable risk-significant equipment. The inspectors determined that the cables were not submerged, that splices were intact, and that appropriate cable support structures were in place. In those areas where dewatering devices were used, such as a sump pump, the device was functional and level alarm circuits were set appropriately to ensure that the cables would not be submerged. In those areas without dewatering devices, the inspectors verified that drainage of the area was available, or that the cables were qualified for submergence conditions. The inspectors also reviewed the licensees corrective action documents with respect to past submerged cable issues identified in the corrective action program to verify the adequacy of the corrective actions. The inspectors performed a walkdown of the following underground bunkers/manholes subject to flooding:

  • 1MH117/2MH216, 1MH116/2MH215, and 2MH207.

Documents reviewed are listed in the Attachment to this report.

a. Inspection Scope

The inspectors reviewed the overall pass/fail results of the Biennial Written Examination, and the Annual Operating Test, administered by the licensee from July 30 through August 31, 2012, required by 10 CFR 55.59(a). The results were compared to the thresholds established in Inspection Manual Chapter 0609, Appendix I, Licensed Operator Requalification Significance Determination Process," to assess the overall adequacy of the licensees Licensed Operator Requalification Training (LORT) program to meet the requirements of 10 CFR 55.59.

This inspection constituted one annual licensed operator requalification inspection sample as defined in IP 71111.11A.

b. Findings

No findings were identified.

.4 Biennial Review

a. Inspection Scope

The following inspection activities were conducted during the weeks of August 13 and August 20, 2012, to assess: 1) the effectiveness and adequacy of the facility licensees implementation and maintenance of its systems approach to training (SAT) based LORT program, put into effect to satisfy the requirements of 10 CFR 55.59; 2) conformance with the requirements of 10 CFR 55.46 for use of a plant referenced simulator to conduct operator licensing examinations and for satisfying experience requirements; and 3) conformance with the operator license conditions specified in 10 CFR 55.53.

The documents reviewed are listed in the Attachment to this report.

  • Problem Identification and Resolution (10 CFR 55.59(c); SAT Element 5 As Defined in 10 CFR 55.4): The inspectors evaluated the licensees ability to assess the effectiveness of its LORT program and the ability to implement appropriate corrective actions to maintain its LORT Program up-to-date.

The inspectors reviewed documents related to the plants operating history and associated responses (e.g., plant issue matrix and performance review reports; recent examination and inspection reports; licensee event reports).

The inspectors reviewed the use of feedback from operators, instructors, and supervisors as well as the use of feedback from plant events and industry experience information. The inspectors reviewed the licensees quality assurance oversight activities, including licensee training department self-assessment reports.

  • Licensee Requalification Examinations (10 CFR 55.59(c); SAT Element 4 As Defined in 10 CFR 55.4): The inspectors reviewed the licensees program for development and administration of the LORT biennial written examination and annual operating tests to assess the licensees ability to develop and administer examinations that are acceptable for meeting the requirements of 10 CFR 55.59(a).

b. Findings

(1) Diesel Fire Pump
Introduction:

A finding of very low safety significance and associated NCV of TS 5.4.1.d, Fire Protection Program Implementation, was self revealed on June 24, 2012, for the failure of the licensee to test the diesel fire pump in accordance with established procedures recommended by the equipment manufacturer.

Description:

On June 24, 2012, the licensee was performing STP NS13B015, Diesel Driven Fire Pump Periodic Pump Run. Following startup of the diesel fire pump the operator left the room and returned several minutes later to find the diesel engine overheating (coolant boiling and steaming through coolant reservoir cap) and the Water Temp Above Safe Limit light illuminated on the local alarm panel. The operator immediately tripped the engine by placing the hand switch in OFF. Additionally, the control room had received a diesel fire pump trouble light and alarm, but the operator had tripped the engine prior to the control room announcing/communicating the alarm.

The licensee determined that the cause of the engine overheating was due to a corroded coolant reservoir neck and cap that allowed engine coolant to leak and evaporate during engine shutdown (due to vibrations) while performing periodic testing.

On June 24, 2012, the engine was started with a low coolant level which contributed to the short time period that the engine ran prior to overheating. The licensee replaced the coolant reservoir, performed additional required repairs, and retested the engine on June 26, 2012.

The degraded condition of the coolant reservoir was first documented in a condition report dating back to March, 2011. Corrective actions were originally assigned to the Fix-it-Now team, but due to delays in receiving parts and other issues, the licensee delayed scheduling repairs until the third week of July, 2012. From March, 2011, until the failure of the diesel fire pump, there were seven condition reports written documenting the leak of coolant following operation of the diesel fire pump. Only one of those CRs had assigned a work request to add coolant to the reservoir. The licensee stated that normal fluid additions such as oil or coolant were not normally documented, so it is unknown how often coolant was being added to the reservoir.

The inspectors noted that the licensee had not implemented any compensatory measures or additional monitoring to ensure adequate coolant remained in the reservoir until final corrective actions could be implemented.

The licensees apparent cause evaluation identified that STP NS13B015 (as well as other testing procedures associated with the diesel fire pump), contained a step that stated, verify engine coolant is visible in the tank on top of the east end of the engine.

In order to perform this step, the operator would remove the cap on the coolant reservoir and look down into the reservoir to verify whether any coolant was visible (emphasis added). The licensee identified that the diesel fire pump engine operation and maintenance manual stated, in part, to keep cooling system filled to the operating level, keep cooling system completely filled, and add coolant as needed to completely fill the system. The inspectors determined that the STP NS13B015 did not clearly state the requirement to maintain the system full as required by the equipment manufacturer, and was contrary to the Duane Arnold Energy Center (DAEC) Fire Plan Volume 1, Section 8, which states, in part, that the fire protection systems are periodically tested and maintained in accordance with established procedures recommended by equipment manufacturers. The DAEC Fire Plan is the primary procedure by which Duane Arnold establishes, implements, and maintains the fire protection program under TS 5.4.1.d.

Analysis:

The inspectors determined that failing to test the diesel fire pump in accordance with established procedures recommended by the equipment manufacturer was a performance deficiency because it was a failure to meet a TS requirement, and the cause was reasonably within the licensees ability to foresee and prevent, and should have been corrected.

The performance deficiency was determined to be more than minor and a finding because it was associated with the Protection Against External Factors (Fire) attribute of the Mitigating Systems Cornerstone, and adversely affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, the diesel fire pump is an important piece of equipment to aid in the licensees ability to combat a fire.

In accordance with IMC 0609, Significance Determination Process, Attachment 0609.04, Phase 1 - Initial Screening and Characterization of Findings, Table 3b the inspectors determined the finding degraded the fire protection defense-in-depth strategies. The inspectors determined that Appendix F was not an effective tool in evaluating this finding. An NRC Regional Senior Risk Analyst evaluated the finding using the Duane Arnold Standardized Plant Analysis Risk External Events Model, Version 8.22, SAPHIRE Version 8.0.8.0. In accordance with the Risk Assessment of Operational Events Handbook, because the pump failed on June 24, 2012, and the last successful test was performed on June 3, 2012, the exposure period assumed was 11-days, which is one-half of the time period between the failure of the pump and its last successful test.

The Senior Risk Analyst ran the model with the diesel fire pump failed for the 11-day period and the resultant CDF was 4.5E-8/yr. The dominant sequence was a weather-related loss of offsite power initiating event, failure of suppression pool cooling, failure to recover offsite power within 10-hours, failure of shutdown cooling, failure of containment spray, and failure of late injection. The risk result represented a finding of very low risk significance (Green).

The inspectors determined that the contributing cause that provided the most insight into the performance deficiency was associated with the cross-cutting aspect of Problem Identification and Resolution, having Corrective Action Program components, and involving the licensee taking appropriate corrective actions to address safety issues and adverse trends in a timely manner commensurate with their safety significance and complexity. Specifically, the licensee had a recurring problem with coolant spilling out of the coolant reservoir during the end of diesel fire pump testing and never identified the adverse trend that required compensatory measures to ensure the coolant reservoir remained full of water. P.1(d)

Enforcement:

TS 5.4.1.d requires the licensee to establish, implement and maintain written procedures covering implementation of the Fire Protection Program. The Duane Arnold Energy Center (DAEC) Fire Plan implements the licensees fire protection program. Section 8.0 of DAEC Fire Plan, Volume 1, Section 8, Revision 61, states, in part, that, the fire protection systems are periodically tested and maintained in accordance with established procedures recommended by equipment manufacturers.

The DAEC diesel fire pump engine was manufactured by Cummins and the Operation and Maintenance Manual from Cummins states, keep the cooling system completely filled, and to, add coolant as needed to completely fill the system.

Contrary to the above, on June 24, 2012, the licensee failed to implement the requirements of the fire protection program. Specifically, STP NS13B015, Diesel Driven Fire Pump Periodic Pump Run only required that engine coolant be visible in the coolant reservoir and did not require that the diesel fire pump coolant system be completely filled. Because this violation was of very low safety significance and was entered into the licensees CAP as CR 1778882, the violation is being treated as an NCV, consistent with Section 2.3.2 of the NRC Enforcement Policy (NCV 05000331/2012004-01, Diesel Fire Pump Overheating due to Inadequate Test Procedure).

1R13 Maintenance Risk Assessments and Emergent Work Control

a. Inspection Scope

The inspectors reviewed the licensee's evaluation and management of plant risk for the maintenance and emergent work activities listed below affecting risk-significant and safety-related equipment to verify that the appropriate risk assessments were performed prior to removing equipment for work:

  • Plant Air Supply Cooling Water Valve Control Relay Failure;
  • Work Week 1230 Risk; and
  • B SBGT Heater Control Panel Blown Fuse.

These activities were selected based on their potential risk significance relative to the Reactor Safety Cornerstones. As applicable for each activity, the inspectors verified that risk assessments were performed as required by 10 CFR 50.65(a)(4) and were accurate and complete. When emergent work was performed, the inspectors verified that the plant risk was promptly reassessed and managed. The inspectors reviewed the scope of maintenance work, discussed the results of the assessment with the licensee's probabilistic risk analyst or shift technical advisor, and verified plant conditions were consistent with the risk assessment. The inspectors also reviewed TS requirements and walked down portions of redundant safety systems, when applicable, to verify risk analysis assumptions were valid and applicable requirements were met. Specific documents reviewed during this inspection are listed in the Attachment to this report.

This inspection constituted three maintenance risk assessments and emergent work control samples as defined in IP 71111.13-05.

b. Findings

No findings were identified.

1R15 Operability Determinations and Functional Assessments

.1 Operability Evaluations

a. Inspection Scope

The inspectors reviewed the following issues:

  • Prompt Operability Determination (POD) for Extent of Condition Following CR 01789290; 1VAD042B Remained Intermediate After Bleeding Off Air, and CR 01789292; 1VAD051B Remained Intermediate After Depressurizing;

The inspectors selected these potential operability issues based on the risk significance of the associated components and systems. The inspectors evaluated the technical adequacy of the evaluations to ensure that TS operability was properly justified and the subject component or system remained available such that no unrecognized increase in risk occurred. The inspectors compared the operability and design criteria in the appropriate sections of the TSs and the UFSAR to the licensees evaluations to determine whether the components or systems were operable. Where compensatory measures were required to maintain operability, the inspectors determined whether the measures in place would function as intended and were properly controlled. The inspectors determined, where appropriate, compliance with bounding limitations associated with the evaluations. Additionally, the inspectors reviewed a sampling of corrective action documents to verify that the licensee was identifying and correcting any deficiencies associated with operability evaluations. Documents reviewed are listed in the Attachment to this report.

This inspection constituted five operability evaluation samples as defined in IP 71111.15-05.

b. Findings

No findings were identified.

1R19 Post-Maintenance Testing

a. Inspection Scope

The inspectors reviewed the following post-maintenance activities to verify that procedures and test activities were adequate to ensure system operability and functional capability:

  • Testing of 1K03 CB/SBGT Instrument Air Compressor Following Corrective Maintenance;
  • Testing of SBLC System Following Corrective Maintenance;
  • Testing of B SBGT Following Pre-Planned Maintenance;
  • Testing of Diesel Fire Pump Following Pump Replacement;
  • Testing of B CBC Following Temperature Load Controller and Temperature Control Valve Replacement; and
  • Testing of Condensate Service Tank (CST) Low Level Instrument Following Corrective Maintenance.

These activities were selected based upon the ability of the structure, system, or component to impact risk. The inspectors evaluated these activities for the following (as applicable): the effect of testing on the plant had been adequately addressed; testing was adequate for the maintenance performed; acceptance criteria were clear and demonstrated operational readiness; test instrumentation was appropriate; tests were performed as written in accordance with properly reviewed and approved procedures; equipment was returned to its operational status following testing (temporary modifications or jumpers required for test performance were properly removed after test completion); and test documentation was properly evaluated. The inspectors evaluated the activities against the TSs, the UFSAR, 10 CFR Part 50 requirements, licensee procedures, and various NRC generic communications to ensure that the test results adequately ensured that the equipment met the licensing basis and design requirements. In addition, the inspectors reviewed corrective action documents associated with post-maintenance tests to determine whether the licensee was identifying problems and entering them in the CAP and that the problems were being corrected commensurate with the importance to safety. Documents reviewed are listed in the Attachment to this report.

This inspection constituted seven post-maintenance testing samples as defined in IP 71111.19-05.

b. Findings

No findings were identified.

1R22 Surveillance Testing

a. Inspection Scope

The inspectors reviewed the test results for the following activities to determine whether risk-significant systems and equipment were capable of performing their intended safety function and to verify testing was conducted in accordance with applicable procedural and TS requirements:

  • STP 3.5.1-01B; B Core Spray System Operability Test (In-Service Test);
  • STP 3.3.5.1-23; Functional Test of the Condensate Storage Tank Level (Low)

Instrumentation (Routine);

  • STP 3.8.1-06B; B Standby Diesel Generator Operability Test (Fast Start)

(Routine);

  • STP 3.5.3-02; RCIC System Operability Test (Routine).

The inspectors also observed in-plant activities and reviewed procedures and associated records to determine whether:

  • preconditioning occurred;
  • the effects of the testing were adequately addressed by control room personnel or engineers prior to the commencement of the testing;
  • acceptance criteria was clearly stated, demonstrated operational readiness, and was consistent with the system design basis;
  • plant equipment calibration was correct, accurate, and properly documented;
  • as-left setpoints were within required ranges; and the calibration frequency was in accordance with the TSs, the UFSAR, procedures, and applicable commitments;
  • measuring and test equipment calibration was current;
  • test equipment was used within the required range and accuracy; applicable prerequisites described in the test procedures were satisfied;
  • test frequencies met TS requirements to demonstrate operability and reliability; tests were performed in accordance with the test procedures and other applicable procedures; jumpers and lifted leads were controlled and restored where used;
  • test data and results were accurate, complete, within limits, and valid;
  • test equipment was removed after testing;
  • inservice testing activities were performed in accordance with the applicable version of Section XI, American Society of Mechanical Engineers code, and reference values were consistent with the system design basis;
  • test results not meeting acceptance criteria were addressed with an adequate operability evaluation or the system or component was declared inoperable;
  • safety-related instrument control surveillance test reference setting data were accurately incorporated into the test procedure;
  • actual conditions encountering high resistance electrical contacts were such that the intended safety function could still be accomplished;
  • prior procedure changes had not provided an opportunity to identify problems encountered during the performance of the surveillance or calibration test;
  • equipment was returned to a position or status required to support the performance of its safety functions; and
  • all problems identified during the testing were appropriately documented and dispositioned in the CAP.

Documents reviewed are listed in the Attachment to this report.

This inspection constituted four routine surveillance testing samples and one in-service testing sample as defined in IP 71111.22, Sections -02 and -05.

b. Findings

No findings were identified.

1EP6 Drill Evaluation

.1 Training Observation

a. Inspection Scope

The inspectors observed a simulator training evolution for licensed operators on August 15, 2012, that required emergency plan implementation by a crew of licensed operators. This evolution was planned to be evaluated and included in performance indicator data regarding drill and exercise performance. The inspectors observed event classification and notification activities performed by the crew. The inspectors also attended the post-evolution critique for the scenario. The focus of the inspectors activities was to note any weaknesses and deficiencies in the crews performance and ensure that the licensee evaluators noted the same issues and entered them into the CAP. As part of the inspection, the inspectors also reviewed the scenario package and other documents listed in the Attachment to this report.

This inspection constituted one training evolution with emergency preparedness drill aspects as defined in IP 71114.06-05.

4OA2 Identification and Resolution of Problems

Cornerstones: Initiating Events, Mitigating Systems, Barrier Integrity, Emergency Preparedness, Public Radiation Safety, Occupational Radiation Safety, and Physical Protection

.1 Routine Review of Items Entered into the Corrective Action Program

a. Inspection Scope

As part of the various baseline inspection procedures discussed in previous sections of this report, the inspectors routinely reviewed issues during baseline inspection activities and plant status reviews to verify that the issues were being entered into the licensees CAP at an appropriate threshold, that adequate attention was being given to timely corrective actions, and that adverse trends were identified and addressed. Attributes reviewed included: identification of the problem was complete and accurate; timeliness was commensurate with the safety significance; evaluation and disposition of performance issues, generic implications, common causes, contributing factors, root causes, extent-of-condition reviews, and previous occurrences reviews were proper and adequate; and that the classification, prioritization, focus, and timeliness of corrective actions were commensurate with safety and sufficient to prevent recurrence of the issue.

Minor issues entered into the licensees CAP as a result of the inspectors observations are included in the Attachment to this report.

These routine reviews for the identification and resolution of problems did not constitute any additional inspection samples. Instead, by procedure, these reviews were considered an integral part of the inspections performed during the quarter and documented in Section 1 of this report.

b. Findings

No findings were identified.

.2 Daily Corrective Action Program Reviews

a. Inspection Scope

In order to assist with the identification of repetitive equipment failures and specific human performance issues for follow-up, the inspectors performed a daily screening of items entered into the licensees CAP. This review was accomplished through inspection of the stations daily condition report packages.

These daily reviews were performed by procedure as part of the inspectors daily plant status monitoring activities and, as such, did not constitute any separate inspection samples.

b. Findings

No findings were identified.

.3 Selected Issue Follow-Up Inspection: Measuring and Test Equipment Program

a. Inspection Scope

During a review of items entered in the licensees CAP, the inspectors recognized a corrective action item documenting findings from a licensee nuclear oversight department audit of the measuring and test equipment (M&TE) program. The inspectors reviewed the condition and apparent cause evaluations to determine whether the licensee maintained proper control over M&TE by implementing procedures and associated processes. The inspectors reviewed various documents including the licensees quality assurance program and M&TE program procedures, and interviewed personnel. The inspectors also performed a review of past condition reports documenting instances of M&TE issues to verify that problems were being identified at a low threshold, appropriately evaluated, and whether corrective actions were taken.

The inspectors characterized one issue of concern as a licensee-identified Green finding and NCV of 10 CFR 50, Appendix B, Criterion XII as discussed in Section 40A7.

This review constituted one in-depth problem identification and resolution sample as defined in IP 71152-05.

b. Findings

No findings were identified.

4OA3 Follow-Up of Events and Notices of Enforcement Discretion

.1 (Closed) Licensee Event Report (LER) 05000331/2012-004-0: High Pressure Coolant

Injection (HPCI) Declared Inoperable

a. Inspection Scope

On July 2, 2012, the licensee declared HPCI inoperable due to the unexpected isolation of the HPCI outboard steam isolation valve and outboard torus suction valve. This isolation was due to a trip of the HPCI steam leak detection (SLD) system. The licensee verified that there was no steam leak in the HPCI room and the licensees investigation identified that there was a broken thermocouple wire in the SLD circuitry. Earlier in the day, the licensee had performed maintenance in the same cabinet as the broken SLD wire, however, no maintenance was performed on that particular wire. Following replacement and testing of the broken wire, the licensee declared HPCI operable.

The inspectors reviewed the licensees root cause evaluation (RCE). The licensee determined that a recorder modification (containing the broken wire) was installed in 2007. It is suspected that the broken wire was stretched at the time of installation and then it was potentially stretched even more and weakened during maintenance earlier in the day on July 2, 2012. The licensee was unable to definitively determine why the open circuit was sensed nearly 50 minutes following completion of the maintenance in the cabinet; however, according to the RCE the suspected causes were either the spring force created due to the maintenance applied to the necked wire over the 50 minute delay period causing failure or increased resistance causing localized melting of the wire and subsequent failure.

Corrective action included installing signs inside the cabinets containing these wires warning of their fragility. The licensee also planned to inspect other wires associated with the same modification for signs of necking and stretching, replacing wires as necessary, and installing wire hold-downs to provide some stress relief to the installed wires.

Documents reviewed are listed in the Attachment to this report.

This inspection constituted one event follow-up review sample as defined in IP 71153-05.

b. Findings

No findings were identified.

4OA5 Other Activities

.1 Licensee Strike Contingency Plans

a. Inspection Scope

The inspectors reviewed the licensees work stoppage plans to determine if the plans adequately addressed the areas of reactor operations, emergency planning, facility security, fire protection, technical specifications, and other regulatory requirements in the event of an employee strike or management lockout. The inspectors reviewed records and conducted interviews with licensee staff to verify that qualified personnel would be available to meet the minimum requirements for safe operation of the plant, if a strike or lockout were to occur. No actual work stoppage occurred during the inspection period.

b. Findings

No findings were identified.

.2 (Discussed) NRC Temporary Instruction (TI) 2515/187, Inspection of Near-Term Task

Force Recommendation 2.3 Flooding Walkdowns, and NRC TI 2515/188, Inspection of Near-Term Task Force Recommendation 2.3 Seismic Walkdowns

a. Inspection Scope

Inspectors accompanied the licensee on a sampling basis during their flooding and seismic walkdowns to verify that the licensees walkdown activities were conducted using the methodology endorsed by the NRC. These walkdowns were being performed at all sites in response to a letter from the NRC to licensees, entitled Request for Information Pursuant to Title 10 of the Code of Federal Regulations 50.54(f) Regarding Recommendations 2.1, 2.3, and 9.3, of the Near-Term Task Force Review of Insights from the Fukushima Dai-Ichi Accident, dated March 12, 2012 (ADAMS Accession No.

ML12053A340).

3 of the March 12, 2012, letter requested licensees to perform seismic walkdowns using an NRC-endorsed walkdown methodology. Electric Power Research Institute (EPRI) document 1025286 titled, Seismic Walkdown Guidance, (ADAMS Accession No. ML12188A031) provided the NRC-endorsed methodology for performing seismic walkdowns to verify that plant features credited in the current licensing basis for seismic events were available, functional, and properly maintained.

4 of the letter requested licensees to perform external flooding walkdowns using an NRC-endorsed walkdown methodology (ADAMS Accession No.

ML12056A050). Document NEI 12-07 titled, Guidelines for Performing Verification Walkdowns of Plant Protection Features, (ADAMS Accession No. ML12173A215)provided the NRC-endorsed methodology for assessing external flood protection and mitigation capabilities to verify that plant features credited in the CLB for protection and mitigation from external flood events were available, functional, and properly maintained.

As part of the inspection for TI 2515/187, the inspectors performed IP 71111.01, Adverse Weather, Section 02.04; as documented in Section 1R01 of this report.

Due to the scheduling of the licensees walkdowns, all inspection requirements were unable to be completed as defined in TI 2515/187 and TI 2515/188. Inspection activities (additional walkdowns of inaccessible areas and independent walkdowns by the inspectors) under TI 2515/187 and TI 2515/188 will continue into the 4th quarter of the 2012 baseline inspection period and documented when complete.

b. Findings

Findings or violations associated with the flooding and seismic walkdowns, if any, will be documented in the 4th quarter integrated inspection report.

4OA6 Management Meetings

.1 Exit Meeting Summary

On October 4, 2012, the inspectors presented the inspection results to Mr. R. Anderson, Site Vice President, and other members of the licensee staff. The licensee acknowledged the issues presented. The inspectors confirmed that none of the potential report input discussed was considered proprietary.

.2 Interim Exit Meetings

Interim exits were conducted for:

  • On August 24, 2012, the operator licensing inspectors presented the 71111.11B inspection results to Mr. R. Anderson, and other members of the licensee staff.

The licensee acknowledged the issues presented.

The inspectors confirmed that none of the potential report input discussed was considered proprietary. Proprietary material received during the inspection was returned to the licensee.

4OA7 Licensee-Identified Violations

The following violation of very low significance (Green) was identified by the licensee and is a violation of NRC requirements which meets the criteria of the NRC Enforcement Policy for being dispositioned as an NCV.

  • The licensee identified a finding of very low safety significance (Green) and an associated NCV of 10 CFR 50, Appendix B, Criterion XII, Control of Measuring and Test Equipment, on June 7, 2012, when the licensee concluded in Condition Evaluation 01781809 that Administrative Control Procedure (ACP) 1408.8, Control of Measuring and Test Equipment, Revision 21 was not adequate to ensure proper controls of M&TE at the station. This was evidenced by several instances over the prior two years where various M&TE was identified as missing during weekly verifications of M&TE inventory. Corrective actions included a revision to ACP 1408.8 to include requirements for M&TE checkout prior to removal from storage locations, and improvements to the M&TE checkout process.

The failure to establish measures to assure controls of M&TE was a performance deficiency. The performance deficiency was determined to be more than minor and a finding because, if left uncorrected, the performance deficiency would have the potential to lead to a more significant safety concern. Specifically, failing to properly control M&TE would have the potential to impact the quality of maintenance, or results of testing of safety-related equipment.

The inspectors evaluated the finding in accordance with IMC 0609, Significance Determination Process, Attachment 0609.04, Initial Characterization of Findings, and then proceeded to IMC 0609, Appendix A, The Significance Determination Process for Findings At-Power, Exhibit 2 Questions. Since the inspectors answered No to Question 4, the finding screened as very low safety significance (Green).
