SUMMARY

Integrated Inspection Report 05000261/2017001; January 1, 2017, through March 31, 2017; Duke Energy Progress, Inc., H. B. Robinson Steam Electric Plant, Unit 2, Refueling and Other

Outage Activities.

The report covered a 3-month period of inspection by resident inspectors and five regional inspectors. There were two NRC-identified violations documented in this report. The significance of inspection findings are indicated by their color (i.e., greater than Green, or Green, White, Yellow, Red) and determined using Inspection Manual Chapter (IMC) 0609,

"Significance Determination Process" (SDP), dated April 29, 2015. The cross-cutting aspects are determined using IMC 0310, "Aspects within the Cross-Cutting Areas," dated December 4, 2014. All violations of NRC requirements are dispositioned in accordance with the NRC's Enforcement Policy, dated November 1, 2016. The NRC's program for overseeing the safe operations of commercial nuclear power reactors is described in NUREG-1649, "Reactor Oversight Process (ROP)," Revision 6.

Cornerstone: Barrier Integrity

Green.

An NRC-identified Green non-cited violation (NCV) of 10 CFR Part 50.55a, "Codes and Standards," was identified for the failure to perform general visual examinations of moisture barriers in the containment leak-chase channel test connections in accordance with the American Society of Mechanical Engineers Boiler and Pressure Vessel Code (ASME BPVC),Section XI, Subsection IWE,

Requirements for Class MC and Metallic Liners of Class CC Components of Light-Water Cooled Plants

. Following the inspectors' identification of this issue, the licensee initiated actions to conduct the required visual examinations during the March 2017 refueling outage and initiated actions to revise the containment inservice inspection (ISI) plan such that the required examinations will be performed in the future. This issue was entered into the licensee's corrective action program (CAP)as nuclear condition report (NCR) 02109909.

The failure to conduct the required visual examination of moisture barrier material in accordance with the ASME BPVC,Section XI, Subsection IWE, was a performance deficiency (PD). The finding was of more than minor significance because, if left uncorrected, it had the potential to lead to a more significant safety concern.

Specifically, visual examinations of moisture barriers associated with the containment leak-chase channel test connections provide assurance that the containment metal liner and liner seam welds remain capable of performing its intended safety function. In the absence of such examinations, corrosive conditions at the moisture barrier (concrete-to-tubing interface) could go undetected. As a result, degradation of inaccessible portions of the containment liner could progress to challenge the containment operational capability. Using IMC 0609, Attachment 4, "Initial Characterization of Findings," the finding was determined to affect the Barrier Integrity Cornerstone because it involved ISI program examinations designed to identify degradation of the containment metal liner. The inspectors screened the finding using IMC 0609, Appendix A, "The Significance Determination Process (SDP) For Findings At-Power," "Exhibit 3 - Barrier Integrity Screening Questions," and determined that the finding was of very low safety significance (Green) because it did not represent an actual open pathway in the physical integrity of the containment.

The inspectors reviewed this performance deficiency for cross-cutting aspects as required by IMC 0310, "Components With Cross-Cutting Aspects." The finding was determined to be reflective of present licensee performance because in 2014, the licensee did not take effective corrective actions to implement the ASME BPVC requirements in the Subsection IWE Program, when a reasonable opportunity was available through the review of NRC Information Notice (IN) 2014-07, which highlighted this industry-wide problem. Therefore, the finding was assigned a cross-cutting aspect in the resolution component of the problem identification and resolution cross-cutting area (P.3). (Section 1R20)

• Severity Level IV. An NRC-identified severity level IV (SL IV) NCV of 10 CFR 50.9(a), "Completeness and Accuracy of Information," was identified for the licensee's failure to provide complete and accurate information in a license amendment request (LAR), dated November 19, 2015, requesting extension of the containment leak rate test frequencies required by various containment technical specifications (TSs). In this LAR, the licensee incorrectly stated that they had revised their ASME BPVC,Section XI, Subsection IWE program to include visual examinations of the test connections in the leak-chase channel penetration pressurization system (PPS), when in fact, the program had not been revised and the examinations had not been performed. This information was material to the NRC because it was used, in part, as the basis for the approval and issuance of License Amendment 247, dated October 11, 2016, extending the TS containment leak rate test frequencies. The licensee's corrective actions included conducting the visual examinations of the test connections in the leak-chase channel PPS during the ongoing refueling outage in March 2017 and initiating actions to add the visual examination requirements to their Subsection IWE program. This issue was entered into the licensee's CAP as NCR 02110516.

The failure to provide complete and accurate information in accordance with 10 CFR 50.9(a) for the LAR associated with License Amendment 247 is a violation of NRC requirements. This violation was screened against the ROP guidance in IMC 0612,

Appendix B, "Issue Screening," and no associated ROP finding was identified. The inspectors evaluated this issue using the Traditional Enforcement process because it had the potential to impact the NRC's ability to perform its regulatory function. Specifically, the violation impacted the regulatory process, in that the inaccurate information was material to the NRC's review and acceptance of licensee actions to address the industry-wide operating experience discussed in NRC IN 2014-07. Based on licensee inaccurate information that they had addressed IN 2014-07 by revising their containment ISI program to perform visual inspections of accessible tubing in the containment leak-chase channel PPS system, the NRC staff concluded that the licensee was properly implementing the ASME BPVC,Section XI, Subsection IWE program.

In accordance with the guidance in Sections 2.2 and 6.9 of the NRC Enforcement Policy, the inspectors determined this is an SL IV violation, because had the information been complete and accurate at the time provided, it likely would have resulted in the need for further clarification of the licensee's actions to address NRC IN 2014-07, but would not have caused the NRC to change its decision to issue the license amendment or resulted in substantial further inquiry. Also, on March 23, 2017, the licensee completed the visual examinations of the subject tubing in the leak-chase channel system and did not identify any significant degradation. In accordance with IMC 0612, Appendix B, traditional enforcement issues are not assigned a cross-cutting aspect. (Section 1R20)

A violation of very low safety significance that was identified by the licensee has been reviewed by the NRC. Corrective actions taken or planned by the licensee have been entered into the licensee's corrective action program (CAP). This violation and corrective action tracking number is listed in Section 4OA7 of this report.

• PT, Work Order 13528492-01, Rejectable Indication Discovered on Weld 245/29, ASME Code Class 1.

Pressurized Water Reactor Vessel Upper Head Penetration Inspection Activities The inspectors verified that for the Unit 2 reactor vessel closure head, a bare metal visual examination based on ASME Code Case N-729-1, combined with a sample of examination results from the 2015 examination efforts, was not required this outage.

The inspectors also concluded that based on H.B. Robinson Relief Request No. 11, a volumetric examination of the reactor closure head penetrations was not required during this outage, in accordance with the requirements of ASME Code Case N-729-1 and 10 CFR 50.55a(g)(6)(ii)(D).

The licensee did not identify any relevant indications that were accepted for continued service on the vessel head. Additionally, the licensee did not perform any welding repairs to the vessel head penetrations since the beginning of the last Unit 2 refueling outage; therefore, no NRC review was completed for these inspection procedure (IP)

attributes.

Boric Acid Corrosion Control Inspection Activities The inspectors reviewed the licensee's boric acid corrosion control (BACC) program activities to determine if the activities were implemented in accordance with the commitments made in response to NRC Generic Letter 88-05, "Boric Acid Corrosion of Carbon Steel Reactor Pressure Boundary Components in PWR Plants," and applicable industry guidance documents. Specifically, the inspectors performed an onsite records review of procedures and the results of the licensee's containment walkdown inspections performed during the current refueling outage. The inspectors also interviewed the BACC program owner, conducted an independent walkdown of containment to evaluate compliance with licensee's BACC program requirements, and verified that degraded or non-conforming conditions, such as boric acid leaks, were properly identified and corrected in accordance with the licensee's BACC and CAPs.

The inspectors reviewed the following engineering evaluations, completed for evidence of boric acid leakage, to determine if the licensee properly applied applicable corrosion rates to the affected components; and properly assessed the effects of corrosion induced wastage on structural or pressure boundary integrity in accordance with the licensee procedures.

.1 Failure to Conduct Visual Examinations of Containment Moisture Barriers

Introduction:

The NRC identified a Green NCV of 10 CFR Part 50.55a, "Codes and Standards," for the licensee's failure to conduct general visual examinations of accessible test connections in the containment leak-chase channel PPS that provided a moisture barrier to the containment basemat liner seam welds in accordance with ASME BPVC,Section XI, Subsection IWE.

Description:

During the refueling outage, the inspectors conducted an inspection of accessible components in the licensee's c ontainment leak-chase channel PPS. This system consists of steel channel sections that are welded continuously over the entire containment basemat metallic shell and liner plate seam welds that were embedded in the 3 to 4 feet thick concrete floor during construction. The network of channels are subdivided into zones, with a test connection for each zone. These test connections consist of 1/4-inch carbon steel tubes that penetrate through the back of the channel and is seal welded to the channel. The tubes extend up through the concrete floor slab to a height of 3 to 4 feet above the floor elevation and are connected to a series of piping

manifolds that are part of the PPS. This sy stem allows for pressure testing of the containment seam welds for leak-tightness during original plant construction and during operation. Since these test connection tubes are at the concrete-to-metal interface of the containment floor and are prone to being wetted, they are susceptible to experiencing corrosion. If such degradation were to occur, this could allow moisture intrusion into the leak-chase channels and corrosion degradation of inaccessible areas of the containment shell/liner within the channels.

In May 2014, the NRC issued IN 2014-07, which discussed the applicability of the ASME BPVC,Section XI, Subsection IWE requirements to the leak-chase channel system.

Beginning with the 1998 Edition with the 2000 Addenda,Section XI of the ASME BPVC, Subsection IWE, Table IWE-2500-1, Category E-A, "Containment Surfaces," Item E1.30, "Moisture Barriers," specifically requires a general visual examination of 100 percent of moisture barriers every inspection period. This general visual examination includes moisture barrier materials intended to prevent intrusion of moisture against inaccessible areas of the pressure retaining metal containment shell or liner at concrete-to-metal interfaces and at metal-to-metal interfaces which are not seal welded. Based on review of the licensee's leak-chase system configuration, the inspectors determined that the licensee was required to conduct general visual examinations of the test connections at the concrete-to-tube floor interface to ensure there was no corrosion or breach that could allow a pathway for moisture into the leak-chase channel system.

Based on review of the licensee's containment ISI inspection program found in document RNP-PM-006, "Second Ten-Year Interval Inservice IWE/IWL Inspection Program," Rev. 3, the inspectors noted that visual examination of the test connections was not being performed. The inspectors subsequently reviewed the licensee's response to IN 2014-07, which was documented in Action Request (AR) 00686620. The AR was closed (with status as complete) on November 5, 2014. The AR evaluation recognized that the licensee's Containment (Subsection IWE) ISI program did not currently include visual examination of the leak-chase connections and stated that actions would be taken to add these examinations to the program and schedule the examinations during the upcoming May 2015 refueling outage. However, neither of these intended items were assigned formal action assignments and as a result, had not been completed as intended. Since the licensee had no evidence that any other past inspections of the leak-chase channel test connections had been performed, the current condition of the test connections was called into question. This issue was considered an outstanding operability concern that required resolution prior to the unit re-entering Mode 4 from the ongoing refueling outage. The licensee took immediate actions to develop ISI visual examination procedures and conducted the visual examinations on March 23, 2017. The inspectors reviewed the results of the examinations. While many of the tubes at the concrete floor interface had lost some portion of their exterior protective coating, exhibited dark discoloration of the bare metal surfaces, or had evidence of surface irregularities, none of the tubes were degraded to the extent that would have allowed moisture intrusion. Based on this, the inspectors concluded that the licensee had adequately resolved any containment operability concerns.

Analysis:

The licensee's failure to conduct general visual examinations of moisture barrier material in the containment leak-chase channel test connections in accordance with the ASME BPVC,Section XI, Subsection IWE, was a PD. The inspectors determined that this PD was of more than minor significance because, if left uncorrected, it had the potential to lead to a more significant safety concern. Specifically, visual examinations of moisture barriers associated with the containment leak-chase channel test connections provide assurance that the containment metal liner and liner seam welds remain capable of performing its intended safety function. In the absence of such examinations, corrosive conditions at the moisture barrier (concrete-to-tubing interface) could go undetected. As a result, degradation of inaccessible portions of the containment liner could progress to challenge the containment operational capability.

Using IMC 0609, Attachment 4, "Initial Characterization of Findings," the finding was determined to affect the Barrier Integrity Cornerstone because it involved ISI program examinations designed to identify degradation of the containment metal liner. The inspectors screened the finding using IMC 0609, Appendix A, "The Significance Determination Process (SDP) For Findings At-Power," "Exhibit 3 - Barrier Integrity Screening Questions," and determined that the finding was of very low safety significance (Green) because it did not represent an actual open pathway in the physical integrity of the containment. The inspectors reviewed this performance deficiency for cross-cutting aspects as required by IMC 0310, "Components With Cross-Cutting Aspects." The finding was determined to be reflective of present licensee performance because in 2014, the licensee did not take effective corrective actions to implement the ASME BPVC requirements in the Subsection IWE Program when a reasonable opportunity was available through the review of NRC IN 2014-07, which highlighted this industry-wide problem. Therefore, the finding was assigned a cross-cutting aspect in the "Resolution" component of the Problem Identification and Resolution cross-cutting area

(P.3).

Enforcement:

Title 10 of CFR 50.55a, "Codes and Standards," as modified by NRC Final Rule-Making published in the Federal Register dated August 8, 1996, states, in part, that the examination of metallic liners in concrete containments shall satisfy the requirements of ASME BPVC,Section XI, Subsection IWE of the 1992 Edition with the 1992 Addenda through the latest edition, and addenda incorporated by reference in paragraph 10 CFR 50.55a(b)(2). The first containment ISI inspection interval for Robinson for Subsection IWE, effective September 9, 1998, through September 2008, utilizing the 1992 Edition with the 1992 Addenda of ASME Section XI; as well as the current, second containment ISI inspection interval, effective September 9, 2008, through September 8, 2018, utilizing the 2001 Edition with the 2003 Addenda of ASME Section XI, required examination of moisture barriers in concrete containments. Specifically, Subsection IWE, Table IWE-2500-1, Category E-A, "Containment Surfaces," Item E1.30, "Moisture Barriers,

" required a general visual examination of 100 percent of moisture barriers intended to prevent intrusion of moisture against inaccessible areas of the pressure retaining metal containment shell or liner at concrete-to-metal interfaces and at metal-to-metal interfaces.

Contrary to the above, from 1998 to March 2017, for the first and second containment ISI intervals, the licensee failed to perform general visual examinations of 100 percent of moisture barrier material intended to prevent intrusion of moisture through the leak-chase channel test connections to inaccessible areas of the pressure retaining metal containment shell. On March 23, 2017, following identification of the violation by the NRC, the licensee performed visual examinations of required leak-chase test connections during the ongoing refueling outage in accordance with Subsection IWE.

The visual examination did not identify any significant degradation or indications of moisture intrusion into the test connections leading to the leak-chase channels. The licensee planned to revise the Containment ISI Plan to reflect the applicable Subsection IWE requirements. Because this finding is of very low safety significance and has been entered into the licensee's CAP as NCR 02109909, this violation is being treated as an NCV, consistent with Section 2.3.2.a of the Enforcement Policy.

.2 Failure to Provide Complete and Accurate Information Involving LAR

Introduction:

The NRC identified a SL IV NCV of 10 CFR 50.9, "Completeness and Accuracy of Information," for the licensee's failure to provide complete and accurate information in a LAR, dated November 19, 2015, requesting extension of the containment leak rate test frequencies required by various containment related TSs. In

this LAR, the licensee incorrectly stat ed that they had revised their ASME BPVC,Section XI, Subsection IWE program to include visual examinations of the test connections in the leak-chase channel PPS, when in fact, the program had not been revised and the examinations had not been completed.

Description:

On October 11, 2016, the NRC issued License Amendment 247 to Renewed Facility Operating License No. DPR-23, for the H. B. Robinson Steam Electric Plant, Unit No. 2, in part, approving the licensee's request to extend various containment leak rate test frequencies associated with TS 5.5.16, "Containment Leakage Rate Testing Program," TS 3.6.1, "Containment," and TS 3.6.2, "Containment Air Lock." By Duke Energy letter, RNP-RA/15-0090, dated November 19, 2015, the licensee submitted the LAR for the proposed TS changes. While reviewing this amendment and the licensee's associated LAR, the inspectors identified a discrepancy in the licensee's

statements addressing their impact assessment of NRC IN 2014-07. Specifically, the licensee stated the following in their LAR:

"The piping/tubing that go through the concrete have not been previously included in the IWE inspection program to verify that there is no corrosion or a breach near the floor level which would allow moisture to enter in a manner like the plants described

in the IN. The PPS to weld channels was abandoned in the mid-1970s and per the 10 CFR 50.55(b)(2)(ix)(A) requirement; the piping/tubing should be examined closely enough to say that there is not a breach. To provide reasonable assurance that aging effects of the containment liner are being managed, the IWE program was revised to perform visual inspections of accessible tubing in the PPS system from manifold to floor of the Containment."

As previously discussed in Section 1R20.b.1 of this report, the inspectors identified that the licensee had not revised their Subsection IWE program to perform the visual inspections of accessible tubing in the PPS system, as intended, due to the oversight in 2014 involving the failure to implement the corrective actions associated with AR 00686620. Therefore, the statement provided in the LAR was inaccurate and constituted a violation of 10 CFR 50.9, "Completeness and Accuracy of Information."

The licensee initiated NCR 02110516 to address this discrepancy.

Analysis:

The licensee's failure to provide complete and accurate information in accordance with 10 CFR 50.9(a) for the LAR associated with License Amendment 247 is a violation of NRC requirements. This violation was screened against the ROP guidance in IMC 0612, Appendix B, "Issue Screening," and no associated ROP finding was identified. The inspectors evaluated this issue using the Traditional Enforcement process because it had the potential to impact the NRC's ability to perform its regulatory function. Specifically, the violation impacted the regulatory process, in that, the inaccurate information was material to the NRC's review and acceptance of licensee actions to address the industry-wide operating experience discussed in IN 2014-07.

Based on licensee inaccurate information that they had addressed IN 2014-07 by revising their Subsection IWE program to perform visual inspections of accessible tubing in the containment leak-chase channel PPS system, the NRC staff concluded that the licensee was properly implementing the ASME Code,Section XI, Subsection IWE

program. In accordance with the guidance in Sections 2.2 and 6.9 of the NRC Enforcement Policy, the inspectors determined this is a SL IV violation, because had the information been complete and accurate at the time provided, it likely would have resulted in the need for further clarification of the licensee's actions to address IN 2014-07, but would not have caused the NRC to change the decision to issue the license amendment or resulted in substantial further inquiry. Also, on March 23, 2017, the licensee completed the visual examinations of the subject tubing in the leak-chase channel system and did not identify any significant degradation. In accordance with the IMC 0612, Appendix B, traditional enforcement issues are not assigned a cross-cutting aspect.

Enforcement:

Title 10 of CFR 50.9(a), "Completeness and Accuracy of Information," states, in part, that information required by the NRC's regulations, orders, and license conditions shall be complete and accurate in all material aspects. Contrary to the above, on November 19, 2015, the licensee failed to ensure that information provided to the NRC was complete and accurate in all material respects associated with a license amendment request to extend the containment leak rate test frequencies required by TS 5.5.16, "Containment Leakage Rate Testing Program," TS 3.6.1, "Containment," and TS 3.6.2, "Containment Air Lock." Specifically, the licensee stated that they had revised their ASME BPVC,Section XI, Subsection IWE program to include visual examinations of accessible test connections in the leak-chase channel PPS to address industry-wide operating experience discussed in NRC IN 2014-07, when in fact, the examinations had not been added to the Subsection IWE program. This information was material to the

NRC's approval of License Amendment 247. The licensee's corrective actions include conducting the visual examinations of the leak-chase test connections and initiating actions to add the examinations to the Subsection IWE inspection program. In accordance with the guidance in Sections 2.2 and 6.9 of the NRC Enforcement Policy, the inspectors determined this is a SL IV violation, because had the information been complete and accurate at the time provided, it likely would have resulted in the need for further clarification of the licensee's actions to address NRC IN 2014-07, but would not have caused the NRC to change the decision to issue the license amendment or resulted in substantial further inquiry. Because the violation was of SL IV significance and was entered into the licensee's CAP as NCR 02110516, this violation is being treated as a NCV consistent with Section 2.3.2.a of the Enforcement Policy.

Cornerstones: Occupational Radiation Safety and Public Radiation Safety

2RS1 Radiological Hazard Assessment and Exposure Controls

a. Inspection Scope

Hazard Assessment and Instructions to Workers During facility tours, the inspectors directly observed radiological postings and container labeling for areas established within the radiologically controlled area (RCA) of the reactor building, auxiliary building and radiological waste (radwaste) building, and radwaste processing and storage locations. The inspectors directly observed measured radiation dose rates verifying licensee radiation surveys for selected RCA areas. The inspectors reviewed survey records for several plant areas including surveys for airborne radioactivity, gamma surveys with a range of dose rate gradients, surveys for alpha- emitters and other hard-to-detect radionuclides, and pre-job surveys for upcoming tasks. The inspectors also discussed changes to plant operations that could contribute to changing radiological conditions since the last inspection. The inspectors attended pre- job briefings and reviewed Radiation Work Permit (RWP) details to assess communication of radiological control requirements and current radiological conditions to workers.

Control of Radioactive Material The inspectors observed surveys of material and personnel being released from the RCA using small article monitor, personnel contamination monitor, and portal monitor instruments. The inspectors discussed equipment sensitivity, alarm setpoints, and release program guidance with licensee staff. The inspectors also reviewed records of leak tests on selected sealed sources and discussed nationally tracked source transactions with licensee staff.

Hazard Control The inspectors evaluated access controls and barrier effectiveness for selected High Radiation Area (HRA), Locked High Radiation Area (LHRA), and Very High Radiation Area (VHRA) locations and discussed changes to procedural guidance for LHRA and VHRA controls with Radiation Protection (RP) supervisors. The inspectors reviewed implementation of controls for the storage of irradiated material within the spent fuel pool. Established radiological controls, including airborne controls and electronic dosimeter (ED) alarm setpoints, were evaluated for selected Refueling Outage 30 tasks.

In addition, the inspectors reviewed licensee controls for areas where dose rates could change significantly as a result of plant shutdown and refueling operations. The inspectors also reviewed the use of personnel dosimetry including extremity dosimetry and the possible use of multibadging in high dose rate gradients.

Radiation Worker Performance and RP Technician Proficiency

Occupational workers' adherence to selected RWPs and RP technician proficiency in providing job coverage were evaluated through direct observations and interviews with licensee staff. Jobs observed included steam generator work, radiography, and work conducted in the reactor building in high radiation and contaminated areas. The inspectors also evaluated worker responses to dose and dose rate alarms during work activities in high radiation areas.

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

(Closed) Licensee Event Reports (LERs) 05000261/2016-005-00 and 05000261/2016-005-01, Reactor Trip and Automatic System Actuation Due to Weather-Related Loss of Offsite Power

a. Inspection Scope

This LER and its supplement was associated with the events that occurred on

October 8, 2016, associated with a momentary loss of offsite power (LOOP) event and automatic reactor trip on undervoltage due to a grid voltage disturbance during adverse weather conditions associated with Hurricane Matthew. The inspectors reviewed the LERs, the associated CAP reports documenting the event, and discussed the issue with licensee staff. Details of the initial event response were previously evaluated and discussed in Section 4OA3.1 of NRC Inspection Report 05000261/2016004.

The cause of the voltage drop in the Robinson switchyard was due to a fault on a 230 kilovolt switchyard transmission line that was not immediately isolated due to a failed non-safety related fault detection relay that was common to the primary and secondary fault detection circuitry for the transmission line. This relay was subsequently replaced and a design change was initiated to install two fault detection relays, one in the primary and one in the secondary fault detection circuitry, to eliminate the vulnerability. Since this issue involved non-safety related equipment and there was no weakness identified in the existing transmission preventive maintenance relay replacement program, no finding or violation of NRC requirements was identified.

The cause of the inadvertent auxiliary feedwater actuation during post-event recovery actions was due to inadequate guidance in the operations electrical alignment procedure OP-603, "Electrical Distribution." The procedure was revised to provide additional guidance for the infrequently performed condition of restoring power to vital buses following a LOOP event. The inspectors concluded that this inadequate procedure was a violation of 10 CFR 50, Appendix B, Criterion V, "Instructions, Procedures, and Drawings," which requires procedures affecting quality be appropriate to the circumstances. Due to the fact that no actual loss of auxiliary feedwater occurred during the incident and there was no adverse impact on plant operation, the failure to comply with this requirement constituted a violation of minor safety significance that was not subject to enforcement action in accordance with the NRC's Enforcement Policy.

The licensee entered this issue into their CAP as NCR 02068565.

LERs 05000261/2016-005-00 and 05000261/2016-005-01 are closed.

b. Findings

.2 (Closed) Temporary Instruction (TI) 2515/192, Inspection of the Licensee's Interim Compensatory Measures Associated with the Open Phase Condition Design

Vulnerability in Electric Power Systems

a. Inspection Scope

The objective of this performance based TI is to verify implementation of interim compensatory measures associated with an open phase condition (OPC) design vulnerability in electric power systems for operating reactors. The inspectors conducted an inspection to determine if the licensee had implemented the following interim compensatory measures. These compensatory measures are to remain in place until permanent automatic detection and protection schemes are installed and declared operable for OPC design vulnerability. Documents reviewed are listed in the attachment. The inspectors verified the following:

• The licensee had identified and discussed with plant staff the lessons-learned from the OPC events at the U.S. operating plants including the Byron station OPC event and its consequences. This includes conducting operator training for promptly diagnosing, recognizing consequences, and responding to an OPC event.

• The licensee had updated plant operating procedures to help operators promptly diagnose and respond to OPC events on offsite power sources credited for safe shutdown of the plant.

• The licensee had established and continue to implement periodic walkdown activities to inspect switchyard equipment such as insulators, disconnect switches, and transmission line and transformer connections associated with the offsite power circuits to detect a visible OPC.

• The licensee had ensured that routine maintenance and testing activities on switchyard components had been implemented and maintained. As part of the maintenance and testing activities, the licensee assessed and managed plant risk in accordance with 10 CFR 50.65(a)(4) requirements.

b. Findings

The inspectors verified the criteria were met and identified no findings.

4OA6 Meetings, Including Exit

On April 17, 2017, the resident inspectors presented the inspection results to Mr. Kapopoulos and other members of the licensee's staff. The inspectors confirmed that no proprietary information was retained by the inspectors or documented in this

report.

4OA7 Licensee-Identified Violations

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

• 10 CFR Part 50, Appendix B, Criterion XVI, "Corrective Action," states, in part, that measures shall be established to assure that conditions adverse to quality, such as failures, malfunctions, deficiencies, deviations, defective material and equipment, and non-conformances are promptly identified. Contrary to the above, in March 2014, while performing examinations in steam generator 'C' during forced shutdown RFO229F3, the licensee failed to identify a loose part lodged in contact with tube R37C22. The licensee identified the loose part in March 2017 during refueling outage RO30. The licensee verified that indications of the part were detectable during RFO229F3, retrieved the part, verified that degradation caused by the part met all structural integrity requirements, plugged the tube, and removed it

from service. This issue was identified in the licensee's CAP as NCR 0210725. The inspectors evaluated this violation using IMC 0609, "Significance Determination Process," Attachment 0609.04, "Initial Characterization of Findings," and 0609 Appendix A, "The Significance Determination Process (SDP) for Findings At-Power," and determined that the violation was of very low safety significance (Green)because evaluations demonstrated that the tube could sustain three times the differential pressure across it during normal full power steady state operation and that the steam generator did not violate the accident leakage performance criterion.
