SUBJECT:
R.E. GINNA NUCLEAR POWER PLANT, LLC - NRC BIENNIAL PROBLEM IDENTIFICATION AND RESOLUTION INSPECTION REPORT 05000244/2018011
Dear Mr. Hanson:
On March 22, 2018, the U.S. Nuclear Regulatory Commission (NRC) completed on-site inspection activities at your R.E. Ginna Nuclear Power Plant, LLC (Ginna) and discussed the results of this inspection with Mr. William Carsky, Site Vice President, and other members of the Ginna staff. During that discussion your staff requested to provide additional information for consideration. In-office review of the additional information continued by the NRC, and a telephonic exit meeting was conducted on April 19, 2018, with Kyle Garnish, Ginna Regulatory Assurance Manager and other members of the Ginna staff. The results of this inspection are documented in the enclosed report.
The NRC inspection team reviewed the stations corrective action program and the stations implementation of the program to evaluate its effectiveness in identifying, prioritizing, evaluating, and correcting problems, and to confirm that the station was complying with NRC regulations and licensee standards for corrective action programs. Based on the samples reviewed, the team determined that your staffs performance in each of these areas adequately supported nuclear safety. The team identified two findings in the area of Corrective Action Program, Problem Identification.
The team also evaluated the stations processes for use of industry and NRC operating experience information and the effectiveness of the stations audits and self-assessments.
Based on the samples reviewed, the team determined that your staffs performance in each of these areas adequately supported nuclear safety.
Finally the team reviewed the stations programs to establish and maintain a safety-conscious work environment, and interviewed station personnel to evaluate the effectiveness of these programs. Based on the teams observations and the results of these interviews, the team found no evidence of challenges to your organizations safety-conscious work environment.
Your employees appeared willing to raise nuclear safety concerns through at least one of the several means available.
NRC inspectors documented two findings of very low safety significance (Green) in this report.
Both of these findings involved violations of NRC requirements and are being treated as non-cited violations (NCVs) consistent with Section 2.3.2.a of the Enforcement Policy. If you contest the violations or significance, you should provide a response within 30 days of the date of this inspection report, with the basis for your denial, to the U.S. Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington DC 20555-0001; with copies to the Regional Administrator, Region I; the Director, Office of Enforcement, U.S. Nuclear Regulatory Commission, Washington, DC 20555-0001; and the NRC Resident Inspectors at Ginna.

SUMMARY
The U.S. Nuclear Regulatory Commission (NRC) continued monitoring Exelons performance at
Ginna by conducting the biennial problem identification and resolution inspection in accordance with the Reactor Oversight Process. The Reactor Oversight Process is the NRCs program for overseeing the safe operation of commercial nuclear power reactors. Refer to https://www.nrc.gov/reactors/operating/oversight.html for more information.
Based on the samples selected for review, the inspection team concluded that Exelon was generally effective in identifying, evaluating, and resolving problems and that the Exelon effectively used operating experience and self-assessments. The inspectors found no evidence of significant challenges to Exelons safety conscious work environment at Ginna and concluded that the staff are willing to raise nuclear safety concerns through at least one of the several means available.
NRC identified and self-revealing findings and violations are summarized in the table below.

Potential Preconditioning of Turbine Driven Auxiliary Feedwater Surveillance Testing Cornerstone Significance Cross-Cutting Aspect Report Section Reactor Safety - Mitigating Systems
Green NCV 05000244/2018011-01 Closed None.
71152B The NRC identified a Green NCV of 10 CFR Part 50, Appendix B, Criterion XI, Test Control,"
because Exelon established unevaluated preconditioning, with a reasonable doubt of whether the preconditioning was acceptable, prior to testing of the turbine driven auxiliary feedwater pump. This results in the loss of as-found conditions which challenge the capability of the test to assure that the turbine driven auxiliary feedwater pump will perform satisfactorily in service.
Description:
The inspectors observed implementation of licensee Procedure STP-O-16-COMP-T, Auxiliary Feedwater Turbine Pump - Comprehensive Test, on March 7, 2018.
During review of licensee Procedure STP-O-16-COMP-T and the quarterly test, Procedure STP-O-16QT, Auxiliary Feedwater Turbine Pump - Quarterly, the inspectors found that immediately prior to the cold pump start, Exelon altered, manipulated, and adjusted a number turbine driven auxiliary feedwater pump train components as directed by the surveillance procedures. These included flushing the condensate storage tank water aligned to the pump suction through the pump to a drain at the pump discharge for approximately 30 minutes, removing and cleaning the auxiliary feedwater pump lubricating oil cooling water (service water) strainer, validating the functionality of the lubricating oil cooling water (service water)strainer bypass valve and bypass valve controlling differential pressure pressure switch, stopping and starting the alternating current and direct current lubricating oil pumps, and verifying the low oil pressure trip functionality of the turbine trip and throttle valve which fully cycles the trip and throttle valve as well as the governor control valve under no load conditions. Consistent with NRC Inspection Manual Part 9900: Technical Guidance, Maintenance - Preconditioning of Structures, Systems and Components before Determining Operability, the inspectors identified these activities, executed immediately prior to cold pump start, as potential preconditioning and discussed the observations with Exelon staff.
Exelon established processes associated with the assessment of preconditioning under Procedures IP-IIT-2, Inservice Testing Program for Pumps and Valves, and CTP-IST-001, Corporate Technical Position - Preconditioning of Inservice Testing Program Components, which states in part, Preconditioning SHALL be avoided unless an evaluation has been performed to determine that the preconditioning is acceptable. The inspectors asked the licensee if a preconditioning evaluation for Procedures STP-Q-16-COMPT or STP-O-16QT was conducted.
After the pump run on March 7, Exelon chose to perform an evaluation of preconditioning acceptability for the flushing of the pump. The justification for acceptability of this preconditioning was protection of the steam generators from low quality water sitting within the pump. Exelon asserted that impact on the pump test results are negligible without providing the details of the potential as-found conditions masked, failure mechanisms against which the activity was evaluated, or why the lower quality water, which is always with the pump while in a standby lineup, is acceptable for event mitigation.
Exelon discovered a preconditioning evaluation had been performed for the cycling of the turbine trip mechanism on April 13, 2010. The inspectors determined this 2010 preconditioning evaluation was narrowly focused on governor control valve stem binding and did not address any other pump parameters or failure modes that could be masked due to cycling the low oil trip or the cycling of the trip mechanism prior to the surveillance test.
Since Exelon performed a technically inadequate preconditioning evaluation associated with low oil trip testing of the turbine trip function and Exelon had not performed preconditioning evaluations of the impact of flushing water through the pump, the lubricating oil cooling water (service water) activities, or stopping and starting of the lubricating oil pumps in advance of the surveillance as of the end of the inspection, the inspectors have concluded that the activities performed immediately prior to cold pump start during comprehensive and quarterly turbine driven auxiliary feedwater pump surveillance testing are examples of unevaluated preconditioning with a reasonable doubt of whether the preconditioning was acceptable, consistent with NRC Inspection Manual Part 9900 Technical Guidance and Exelon program guidance.
Corrective Actions: Exelon entered this concern into the corrective action program for prioritization, assessment, and resolution. This included a preconditioning evaluation of all of the identified issues. Exelon concluded there was no unacceptable preconditioning and that the operability of the turbine driven auxiliary feedwater system was not adversely affected.
The inspectors have no current operability concerns. This evaluation will be fully reviewed under the baseline inspection program.
Corrective Action Reference: Action requests (ARs) 4111709 and 04119043
Performance Assessment:
Performance Deficiency: The inspectors determined that Exelon did not adequately evaluate pre-test activities for the turbine driven auxiliary feedwater pump comprehensive and quarterly tests for preconditioning as discussed in NRC Inspection Manual Part 9900 Technical Guidance, and required by Ginnas Inservice Test Program guidance and Exelons corporate technical position on preconditioning; and failed to identify that those activities may have constituted unacceptable preconditioning. This performance deficiency was reasonably within the licensees ability to foresee and correct and should have been prevented.
Screening: This finding was more than minor in accordance with IMC 0612, Power Reactor Inspection Reports, Appendix B, Issue Screening, dated January 1, 2018, because the performance deficiency is associated with the Equipment Performance attribute of the Mitigating Systems cornerstone and adversely affects the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. This is also similar to IMC 0612 Appendix E, Examples of Minor Issues, examples 3J and 3K. Specifically, preconditioning of components could mask the actual as-found conditions of the system resulting in an inability to verify operability of the system.
Significance: The inspectors assessed significance of this condition using IMC 0609, 4, Phase 1 - Initial Screening and Characterization of Findings worksheet, which directs the user to IMC 0609 Appendix A, The Significance Determination Process (SDP) for Findings At-Power. In accordance with IMC 0609, Appendix A, Exhibit 2, Mitigating Systems Screening Questions, Section A, Mitigating Systems, Structures or Components and Functionality, the finding screened to be of very low safety significance (Green), because the performance deficiency did not affect system design or qualification, did not result in a loss of safety function, and did not result in the turbine driven auxiliary feedwater train to be out of service for greater than its technical speciation allowed outage time.
Cross Cutting Aspect: No cross cutting aspect was assigned to this finding because the inspectors determined the finding did not reflect present licensee performance.
Enforcement:
Violation: Title 10 CFR Part 50, Appendix B, Criterion XI, Test Control, states, in part, that a test program shall be established to assure that all testing required to demonstrate that structures, systems, and components will perform satisfactorily in service is identified and performed in accordance with written test procedures which incorporate the requirements and acceptance limits contained in applicable design documents.
Contrary to the above, from April 13, 2010 to present, Exelon did not establish an adequate test program, which assured that all testing required to demonstrate the turbine driven auxiliary feedwater system will perform satisfactorily in service, due to potential preconditioning.
Disposition: This violation is being treated as a NCV, consistent with Section 2.3.2 of the Enforcement Policy.
Failure to Procedurally Verify Fuel Transfer Cart Results in Fuel Interference Event Cornerstone Significance Cross-Cutting Aspect Report Section Reactor Safety - Barrier Integrity
Green NCV 05000244/2018011-02 Closed H.12 - HU - Avoid Complacency 71152B A self-revealing Green NCV of Technical Specification 5.4.1.a, Procedures, was identified for the failure of Exelon to operate refueling equipment in accordance with technical procedures in April and May of 2017, which resulted in a fuel interference event, damage to the rod cluster control assembly, and the need for a detailed inspection of a fuel assembly.
Description:
The inspectors identified two examples of failure to follow a required procedure.
Specifically, Exelon Procedures RF-200, Fuel Handling System Checkouts, and RF-302, Fuel Handling Tool Checkout and Operation in Containment, were not followed as discussed below.
- (1) In advance of the Spring 2017 refueling outage on April 20, 2017, Exelon implemented a modification to the fuel transfer system to improve fuel moves between containment and the spent fuel pool. This modification changed the alignment of the transfer cart rails, which resulted in a change to the match-mark locations where the encoder stops the fuel assembly.
The licensee failed to perform adequate post modification testing including verification of fuel transfer cart to rail alignment at these match-marked locations in accordance with Steps 6.2.4.16 and 6.2.4.20 of licensee Procedure RF-200.
- (2) During the Spring 2017 refueling outage, Exelon performed a complete core offload of all 121 fuel assemblies using the modified fuel transfer system in accordance with Procedure RF-302, Attachment 3, Fuel Transfer System Operating Instructions. The licensee did not perform Step 4.6.4 of Procedure RF-302, Attachment 3, which required the operators to verify pointer and target match-marks to confirm fuel transfer cart to rail alignment on the spent fuel pool side. During core reload on May 4, 2017, upon sending the fifth fuel assembly, which was a new fuel assembly, from the spent fuel pool to the reactor side, the fuel transfer system operator confirmed location of the fuel assembly using the encoder position as provided by a lit indication instead of the pointer and target match-marks as required by Step 4.5.4 of Procedure RF-302, Attachment 3. When the fuel transport system operator up-ended the fuel assembly on the reactor side, the rod cluster control assembly installed with the fuel assembly struck the fuel transport tube. The fuel assembly and rod cluster control assembly were immediately sent back to the spent fuel pool for evaluation of potential damage.
Exelon found the affected rod cluster control assembly to be damaged and was removed from service. The licensee performed a detailed inspection of the associated fuel assembly and determined the fuel cladding remained operable. The NRC inspectors reviewed Exelons apparent cause evaluation for this issue and determined that while applicable sections of Procedures RF-200 and RF-302 were documented as completed, fuel handlers did not use cart alignment match-marks to verify fuel assembly position. They had instead relied upon the encoder position of the cart as provided by a lit indication.
Corrective Actions: Exelon revised Procedures RF-200 and RF-302 requiring verification of match-marks via remote visual observation (e.g., camera), including staff signatures for all steps that verify cart fuel and target match-marks, and added a caution identifying the lit encoder position indication as not a valid indication of cart position.
Corrective Action Reference: AR 04006765
Performance Assessment:
Performance Deficiency: Inspectors found that Exelon did not operate refueling equipment in accordance with l Procedures, RF-200 and RF-302, during pre-outage activities, core offload, and core reload in April and May of 2017, which resulted in a fuel interference event, damage to the rod cluster control assembly, and the need for a detailed inspection of a fuel assembly.
This performance deficiency was reasonably within the licensees ability to foresee and correct and should have been prevented.
Screening: This finding was more than minor in accordance with IMC 0612, Power Reactor Inspection Reports, Appendix B, Issue Screening, dated January 1, 2018, because if left uncorrected, the performance deficiency would have the potential to lead to a more significant safety concern. Specifically, the repetitive failure to perform the procedurally required fuel transfer cart position verifications, which resulted in the interference event, the actual damage sustained by the rod cluster control assembly, and the need for a detailed inspection of the fuel assembly, if left uncorrected, would have the potential to result in actual damage to a spent fuel assembly which could challenge the ability of the fuel cladding to remain intact.
Significance: The inspectors assessed significance of this condition using IMC 0609, 4, Phase 1 - Initial Screening and Characterization of Findings worksheet, which directs the user to IMC 0609 Appendix G, Shutdown Operations Significance Determination Process. However, criteria for evaluating fuel handling issues are only contained in IMC 0609 Appendix A, The Significance Determination Process (SDP) for Findings At-Power. Since no criteria exist to evaluate this issue in IMC, Appendix G, the inspectors used the most applicable screening criteria available to make a bounding case and characterize this finding as allowed by IMC 0609, Appendix M, Significance Determination Process Using Qualitative Criteria. The inspectors assessed significance of this fuel handling event in accordance with IMC 0609, Appendix A, Exhibit 3, Barrier Integrity Screening Questions, Section D, Spent Fuel Pool. The finding was determined to be of very low safety significance (Green), because the performance deficiency did not affect fuel pool temperature or level, did not affect neutron absorber capability or result in a fuel bundle being misplaced, and although the performance deficiency resulted in fuel handling errors, it did not cause mechanical damage to fuel clad and a detectible release of radionuclides.
Cross Cutting Aspect: This finding in accordance with IMC 0310, Aspects within the Cross-Cutting Areas, dated December 04, 2014, has a cross-cutting aspect in the area of Human Performance associated with Avoid Complacency, in that Exelon fuel transfer system operators did not recognize and plan for the possibility of mistakes, latent issues, and inherent risk, even while expecting successful outcomes. Specifically, operators failed to recognize the latent issues associated with misalignment of the fuel transfer cart and the inherent risk incurred by the inappropriate cart position verification method used, and did not complete the appropriate procedure step a number of times prior to the interference event occurring. (H.12)
Enforcement:
Violation: Technical Specification 5.4.1.a, Procedures, states in part, Written procedures shall be established, implemented, and maintained covering the following activities: The applicable procedures recommended in Regulatory Guide 1.33, Revision 2, Appendix A, February 1978. Regulatory Guide 1.33, Revision 2, Appendix A, Section 2.k, identifies Refueling Equipment Operation, as a recommended procedure. Exelon Procedures RF-200, Fuel Handling System Checkouts, and RF-302, Fuel Handling Tool Checkout and Operation in Containment, implement this requirement.
Contrary to the above, from April 20, 2017 to May 4, 2017, Exelon staff did not properly implement written procedures RF-200 and RF-302, which resulted in a fuel interference event on May 4, 2017, damage to the rod cluster control assembly, and the need for a detailed inspection of a fuel assembly.
Disposition: This violation is being treated as a NCV, consistent with Section 2.3.2 of the Enforcement Policy.
Observations and Minor Violations/Performance Deficiencies 71152B Corrective Action Program: The team concluded that Exelons corrective action program was generally effective. However, some observations were noted; particularly, a number of issues in the MR program. Specifically,
1. The inspectors reviewed maintenance preventable functional failures (MPFFs) that
occurred on the service air system since 2016. The inspectors noted that diesel driven service air compressor failures on January 12 and December 27, 2017, were documented by Ginna to be the result of vendor guidance not being used correctly in the development of online monitoring of equipment. Based on Ginnas documentation, the inspectors determined that Ginnas basis for the December 2017 failure not being a repetitive MPFF was not adequately justified. Ginna presented the inspectors additional analysis and evaluation of the failure from December 2017, that had not been documented originally, which showed that the maintenance related cause was different than the cause of the failure in January 2017. Therefore, the issue was not a repetitive MPFF and did not constitute a violation of 10 CFR 50.65 (a)(2). Exelon documented the inspectors observation concerning adequate documentation of MPFF causes in AR 04122176. This observation is related to the assessment of the Corrective Action Program Area of Problem Evaluation.
2. The inspectors reviewed 22 maintenance rule functional failures (MRFFs) that
occurred over the last two years, 13 of which were determined to be not maintenance preventable, 9 MPFFs, and zero were repetitive MPFFs. The inspectors determined that three of the 13 issues that Exelon determined were not MPFFs, were maintenance preventable (ARs 02625128, 02630466, and 02633768). The inspectors also noted inconsistencies regarding Exelons documented basis for why MPFFs were or were not determined to be repeat MPFFs. The inspectors determined that all of these MR issues represented performance deficiencies because Exelon was not following their MR performance monitoring Procedure, ER-AA-310-1004. Exelon documented the issue in ARs 04117878 and 04118265. The inspectors determined that these issues do not constitute a violation of 10 CFR 50.65 (a)(2) per the guidance in the NRC Enforcement Manual because the additional MPFFs did not cause any of Exelons MR systems to exceed their performance criteria and the performance deficiency was minor because the issues did not represent a significant programmatic deficiency within the MR program This observation is related to the assessment of the Corrective Action Program Area of Problem Evaluation.
3. The inspectors reviewed two failures of the B containment hydrogen monitor
(ARs 02630466 and 02633768) that occurred in February 2016. The failures were the result of failed 480 VAC current voltage transformers that had internal non-electrolytic capacitors fail due to age. Exelons evaluation of the failures determined that their procurement procedure for the tracking of component shelf-life, PES-S-002, had not been revised to include updated industry guidance that would ensure the appropriate shelf-life of safety-related and augmented quality components are appropriately tracked. The inspectors determined that Exelons corrective action to revise the procedure had not been completed yet and had been extended multiple times leaving the program vulnerable to the same failure mode. The inspectors also determined that no extent of condition had been performed on other components tracked by the shelf-life program. This performance deficiency is of minor risk significance because the aged components either were not yet installed in the plant, failures were identified during post maintenance testing, and the equipment failures did not impact the Barrier Integrity cornerstone objective. Exelon documented these issues in ARs 02657276 and 02657285. This observation is related to the assessment of the Corrective Action Program Area of Problem Evaluation.
4. The inspectors reviewed corrective actions associated with NCV
05000244/2015002-02, Inadequate Procedure Implementation Results in Inadvertent Entry into 72-Hour Technical Specification Action Statement. Exelons evaluation of the event determined that improper tool usage, while lifting leads to support a power supply replacement, caused the inverter swap. Exelons corrective actions included revising Procedure M-71.4, Removal and/or Installation of Modules Within Defeated or Out of Service Instrument Loops, to provide clear direction that only nonconductive tools should be used to perform the activity. The inspectors determined that the 2015 procedure included the caution, however subsequent versions did not include this caution, and that there were no procedure change request forms that accounted for the revisions not including the caution. The inspectors reviewed this issue using IMC 0612, Appendix B, Issue Screening, and determined this issue was a minor violation of Technical Specification 5.4.1.a, Procedures, because the issue was administrative in nature, workers had knowledge of the precaution due to previously completed corrective actions, and the issue had not repeated. Exelon documented the issue in AR 04114953. This observation is related to the assessment of the Corrective Action Program Area of Timely and Effective Corrective Actions.
Observation and Minor Performance Deficiency 71152B Operating Experience: The team identified some issues in Exelons incorporation of lessons learned from industry and NRC operating experience into station programs, processes, and procedures. This observation also supports the assessment of the MR.
The inspectors reviewed two equipment failures in the service air system (ARs 02639792 and 03962433) both of which had similar industry operating experience that were determined to have not been reviewed by Exelon prior to each failure. Exelon documented the issue in the ARs noted above. For these failures, Exelon identified that valid operating experience had not been evaluated; however, the failures were appropriately classified as MRFFs when this fact was identified. The failures did not result in a loss of system or train function. Therefore this does not constitute a violation of NRC requirements and the performance deficiency is minor.
Observation 71152B Self-Assessments and Audits: The team identified some issues in Exelons use of audits and self-assessments. These issues support the observation of weakness in the MR program.
1. Maintenance Rule Program Focused Area Self-Assessment (FASA) dated
June 30, 2016 (FASA 02565710) - The inspectors noted that the FASA did not meet Objective #3 of the self-assessment, to review equipment failures of two MR systems since the last FASA, specifically only one system was reviewed. Exelon documented the issue in AR 04117874.
2. Nuclear Oversight (NOS) Corrective Action Program Audit dated March 29, 2017
(AR 3977544) - The inspectors noted the audit did not include a review of the MR program and that the audits corrective actions did not address that three of eight operating experience reviews contained errors related to accurate documentation.
Exelon documented the issue in AR 04117882.
Observation 71152B Safety Conscious Work Environment: The team found no evidence of challenges to Exelons organizations safety-conscious work environment. Site employees appeared willing to raise nuclear safety concerns through at least one of the several means available.
Observation 71152B Review of Corrective Actions Related to Greater-than-Green Findings That Were Not Completed by the End of the Associated Supplemental Inspection: The team reviewed the corrective actions, open at the time of completion of the documented IP 95001 Supplemental Inspection (ML16333A024), dated November 28, 2016, associated with a White NOV in the Emergency Preparedness Cornerstone. The team verified these corrective actions had been completed as scheduled. The team did not identify any new performance deficiencies and did not document any additional observations.
EXIT MEETINGS AND DEBRIEFS
On March 22, 2018, the inspectors presented the biennial problem identification and resolution initial inspection results to Mr. William Carsky, Site Vice President, and other members of the Ginna staff. During that discussion your staff requested to provide additional information for consideration. In-office review of the additional information continued by the NRC, and a telephonic exit meeting was conducted on April 19, 2018 with Kyle Garnish, Ginna Regulatory Assurance Manager and other members of the Ginna staff. Inspectors verified no proprietary information was retained or documented in this report.
