1 sample)

a. Inspection Scope

The inspectors conducted a review of NextEras implementation of inservice inspection (ISI) program activities for monitoring degradation of the reactor coolant system (RCS) boundary, risk significant piping and components, and containment systems during the Seabrook Unit 1, OR17. Inspection sample selection was based on the inspection procedure objectives and risk priority of those pressure retaining components in systems where degradation would result in a significant increase in risk. The inspectors observed in-process non-destructive examinations (NDE), reviewed documentation, and interviewed NextEra personnel to verify that the NDE examination activities performed as part of the Seabrook Unit 1 ISI program were being conducted during the Seabrook Interval 3, Period 2, 2nd Outage, ISI in accordance with the requirements of American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code Section XI, 2004 Edition, no Addenda. Non-destructive Examination and Welding Activities (Inspection Manual Chapter (IMC) Section 02.01) The inspectors performed direct observations of select NDE activities, and reviewed records of the NDEs listed below. The inspectors reviewed certifications of the NDE technicians performing the examinations. The inspectors verified that the examinations were performed in accordance with approved procedures and that the results were reviewed and evaluated by certified Level III NDE personnel. ASME Code Required Examinations The inspectors observed the remote, bare-metal visual (VT-2) examination of the reactor vessel upper closure head and control rod drive mechanism (CRDM) nozzle penetrations.

The inspectors reviewed the VT-3 direct visual examination data from NextEra examination of the CRDM structural supports to determine whether all results were satisfactory.

The inspectors reviewed the examination data sheets for the post mechanical stress improvement process phased array, outside diameter ultrasonic test inspections and the eddy current (EC), inside weld surface inspections of seven reactor vessel hot leg and cold leg nozzle dissimilar metal safe-end welds. The inspectors verified the examinations were completed in accordance with the applicable Seabrook TSs, ASME Boiler and Pressure Vessel Code,Section XI, 2004 Edition, Title 10 of the Code of Federal Regulations (10 CFR) 50.55a(b)(2)(xiv, xv and xiv), Code Case N-770-1 and the Examination Program Plan (Scan Plan) WDI-PJF-1312142-EPP-001, Revision 0, as submitted to, and reviewed by, the NextEra staff. The inspectors determined whether the examination results were dispositioned in accordance with the applicable requirements for the weld records identified in the list of documents reviewed section of this report.

The inspectors reviewed the data records from the visual examinations of the containment liner concrete pad and floor plugs. The inspectors determined whether NextEra personnel documented the conditions for investigation, repair, and monitoring in accordance with their program requirements.

The inspectors observed the ultrasonic test examination of two ASME Class 2 feedwater nozzle-to-pipe welds (FW 4607-04-19 and FW 4607-04-20) to determine whether the examinations were performed to check for indications of thermal fatigue in the welds and whether the results were properly dispositioned. No new indications were detected, and previously detected indications were confirmed to show that no changes had occurred.

The inspectors reviewed the documentation for a containment liner anomaly on the inside surface of the containment dome. NextEra staff completed a VT-1 remote, visual examination on October 2, 2015. This indication, identified as IWE-15-159-176, was first documented in October 2009, and re-examined in October 2012 and April 2014. NextEra engineering staff evaluated the results and did not identify measureable changes in the length, width, contour or color of the anomaly from 2009 thru 2015. The inspectors noted that NextEra engineers were not able to accurately measure the height of the anomaly due to limitations of their imaging equipment. NextEra staff initiated plans to perform an examination during the next refueling outage. The inspectors determined NextEra staff tracked and dispositioned this indication in accordance with their program requirements. Review of Originally Rejectable Indications Accepted by Evaluation The inspectors determined there were no samples available for review during this inspection that involved examinations with recordable indications that had been accepted for continued service after evaluation. Repair/Replacement Consisting of Welding Activities The inspectors reviewed WO 4036801501, which provided direction to fabricate a diesel fuel system connection to implement design change EC282581. The inspectors reviewed the WO to determine whether welding was completed in accordance with ASME Code welding requirements. Specifically, the inspectors determined whether approved plant welding procedures and parameters were specified and that post-weld quality control examinations were identified. The inspectors verified that the WO contained completed weld traveler information, documentation of completed examinations, and appropriate documentation of the work steps completed by NextEra personnel.

Pressurized Water Reactor Vessel Lower Head Penetration Inspection Activities (IMC Section 02.02) The inspectors reviewed visual inspection records of the bare-metal visual examination (VT-2) of the exterior surface of the Unit 1 lower reactor vessel head surface and instrument penetrations for indications of boric acid leakage in order to confirm appropriate inspection coverage was achieved and to verify that no boric acid leakage or wastage had been observed. The inspectors further verified that NextEra staff took actions, tracked in their CAP, to ensure the lower head surface was sufficiently clean to accurately observe the annulus between the penetrations and the openings in the lower head. The inspectors reviewed the examination records to verify that there was no evidence of boric acid.

Steam Generator (SG) Tube Inspection Activities (IMC Section 02.04) The inspectors reviewed the NextEra degradation assessment report for OR17, and reviewed records associated with a sample of SG tube examinations completed from all four SGs. The inspectors determined the following activities were planned: 1. Base scope of 100 percent full length bobbin coil examinations in all SGs to inspect general tube conditions; 2. Hot and cold leg tube support plate to tube intersections examinations in high stress diameter stress corrosion cracking due to tube bulges and tube expansion transitions near the top of the tube sheet; 3. Examinations of all SGs ubobbin probes, such as small radius U-bends and local profile anomalies; 4. Inspection of cracking near the top of the tube sheet; and 5. Examination of large residual noise tube support plate locations on high-stress tubes for outside diameter stress corrosion cracking and primary water stress corrosion cracking, as well as regions not inspectable with bobbin probes, such as small radius U-bends and local profile anomalies. The inspectors reviewed the scope of the EC examinations to verify that known and potential areas of tube degradation were inspected. The inspectors also verified that examination scope expansion criteria were implemented based upon inspection results, Steam Generator Examination Guidelines. The inspectors verified compliance of these examinations with the Seabrook TSs, the ASME Code,Section XI, and Nuclear Energy Institute (NEI) 97-06, Steam tubes with identified wall wear of 40 percent or greater were plugged. The inspectors reviewed EC examination records and determined NextEra staff identified a single axial indication in SG A, row 20, column 80 that was subsequently plugged in accordance with program requirements. NextEra staff review of EC examination results also identified a defect, due to anti-vibration bar wear in SG A, row 50, column 79, which was plugged during the refueling outage to remove it from service. EC examination results further showed a single axial indication in SG C, row 39, column 46, below the top of the tube sheet in the hot leg, which was plugged in accordance with program requirements. The inspectors determined NextEra staff developed and completed an expansion plan for all four SGs without discovery of further indications. The inspectors verified that NextEra staff completed condition monitoring evaluations for these indications to properly determine, in accordance with program requirements, that in-situ pressure testing was not required in these tubes.

Boric Acid Corrosion Control Inspection Activities (IMC Section 02.03) The components. The inspectors verified the adequacy of VT-2 visual examination results of the bare-metal examination of the Unit 1 reactor pressure vessel lower head penetration nozzle welds that was performed by NextEra personnel during OR17. The inspectors reviewed a sample of photographs and visual inspection documentation records to verify whether indications of boric acid leakage were identified. The inspectors verified that potential deficiencies identified were entered into the CAP and reviewed evaluations of selected deficiencies documented in CRs to verify that the corrective actions were consistent with the requirements of the ASME Code and 10 CFR 50, Appendix B, Criterion XVI. The inspectors also reviewed a sample of engineering evaluations for the above CRs to verify that equipment or components that were wetted or impinged upon by boric acid solutions were properly analyzed for degradation that might impact their function. Identification and Resolution of Problems (IMC Section 02.05) The inspectors reviewed a sample of CRs since the previous refueling outage, and verified that non-conforming conditions associated with ISI and SG inspections were properly identified, evaluated, dispositioned, and appropriately entered into the CAP.

.1 Routine Review of Problem Identification and Resolution Activities

a. Inspection Scope

inspectors routinely reviewed issues during baseline inspection activities and plant status reviews to verify NextEra entered issues into the CAP at an appropriate threshold, gave adequate attention to timely corrective actions, and identified and addressed adverse trends. 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 CAP and periodically attended CR screening meetings. The inspectors also confirmed, on a sampling basis, that, as applicable, for identified defects and non-conformances, NextEra performed an evaluation in accordance with 10 CFR Part 21.

b. Findings

No findings were identified.

.2 Semi-Annual Trend Review

a. Inspection Scope

The inspectors performed a semi-annual review of site issues, as required by Inspection indicate the existence of more significant safety issues. In this review, the inspectors included repetitive or closely-related issues that may have been documented by NextEra outside of the CAP, such as trend reports, PIs, major equipment problem lists, system health reports, MR assessments, and maintenance or CAP backlogs. The inspectors assess CRs written in various subject areas (equipment problems, human performance eview (Section 4OA2.1). Evaluation and Trending Analysis report for the second quarter of 2015, conducted under PI-AA-207-1000, Station Self-Evaluation and Trending Analysis, Revision 5, to verify that NextEra personnel were appropriately evaluating and trending adverse conditions in accordance with applicable procedures. The inspectors evaluated a sample of departments that are required to provide input into the quarterly trend reports, which included the operations and maintenance departments. This review included a sample of issues and events that occurred over the course of the past two quarters to objectively determine whether issues were appropriately considered or determined to be emerging or adverse trends, and in some cases, verified the appropriate disposition of resolved trends. The inspectors verified that these issues were addressed within the scope of the CAP, or through department review and documentation in the quarterly trend report for overall assessment.

b. Findings and Observations

No findings were identified. The inspectors noted that on occasion, potential adverse trends were identified through:

(1) the use of statistical tools available to staff and utilized throughout the quarter to identify statistically significant issues that reach a predetermined threshold, or

(2) cognitive trends by staff or collectively during review by the Management Review Committee (MRC) while screening action requests (ARs). In general, the inspectors noted that new and existing adverse trends, as well as management awareness areas, were consistent with those identified by the NRC through daily CR reviews, including those trends identified as cognitive trends during MRC reviews. For example, the inspectors had identified several issues associated with Maintenance Department -assessments were independently initiated by maintenance personnel to evaluate potential causes of the rework.

.3 Annual Sample: Transmitter Failures

a. Inspection Scope

The inspectors performed an in-actions associated with multiple transmitter spurious indications and failures occurring on site. The entification threshold, problem analysis, extent of condition reviews, compensatory actions, and the prioritization and timeliness of corrective actions to determine whether NextEra was appropriately identifying, characterizing, and correcting problems associated with these transmitter issues and whether the planned or completed corrective actions were appropriate. The basis, and other requirements. The inspectors interviewed engineering and operations personnel to assess the effectiveness of the implemented corrective actions, reasonableness of the planned corrective actions, and to evaluate the extent of any on-going problems.

The inspectors evaluated seven ARs (see below) documenting various transmitter malfunctions and failures. The transmitter issues spanned multiple systems and occurred over a timeframe of approximately 18 months. The review focused on various aspects of the corrective actions and operability process to assess the effectiveness and scope of corrective actions, including trending, and the bases and supporting information for immediate operability evaluations, as applicable. Associated documentation and bases, as well as the MRCs review of operability statements and actions to address weaknesses were assessed as well. The ARs that were reviewed included: Volume control tank level transmitter spurious indication (AR 01972065) Containment building sump level transmitter spiking (AR 01999679) SW jacket water cooling flow transmitter out of tolerance low (AR 01995588) Thermal barrier heat exchanger head pipe level transmitter erratic (AR 02002668) SW jacket water cooling flow transmitter discolored water during calibration (AR 02013241) Volume control tank level deviations (AR 01991967) reactor coolant pump hi-range leakage flow transmitter noisy condition (AR 02011136)

b. Findings and Observations

No findings were identified.

Based on the documents reviewed and discussions with NextEra personnel, the commensurate with their safety significance, and that the actions completed and planned were reasonable to address the issues identified.

.4 Annual Sample:

Motor Control Center Breaker Failure to Trip

a. Inspection Scope

The inspectors performed an in-with CR 1998220, Breaker at 1-EDE-MCC-512 for 1-AS-V-175 Would Not Close. Specifically, a breaker failed to reset several times following manual trip actions during the performance of breaker preventive maintenance.

cause analyses, extent of condition reviews, and compensatory actions, as well as the prioritization and timeliness of corrective actions to determine whether NextEra was appropriately identifying, characterizing, and correcting problems associated with this issue and whether the planned or completed corrective actions were appropriate. The CAP and 10 CFR 50, Appendix B. In addition, the inspectors performed field walkdowns and interviewed appropriate personnel to assess the effectiveness of the implemented corrective actions.

b. Findings and Observations

No findings were identified. NextEra originally suspected a well-known industry phenomenon of hardened grease as the cause of the breaker to not operate as expected during implementation of breaker preventive maintenance in October 2014, under WO 40274287. The inspectors noted that the preventive maintenance included an activity to assess the quality of the grease consistent with the grade characteristics of the National Lubricating Grease Institute, and ision 10. The as-found grease condition of Grade 2 was consistent with grease that is new, and therefore, was not the probable cause of the breaker failure to operate. Subsequent inspections resulted in the replacement of a unitized starter associated with the breaker circuitry. Following successful replacement of the starter, the post-maintenance testing was performed and the breaker operated as designed.

.5 Annual Sample:

Review of Corrective Actions for Alkali-Silica Reaction (ASR) Affected Structures

a. Inspection Scope

During this inspection period, a region-based inspector accompanied Office of Nuclear Reactor Regulation, Division of Engineering and Division of License Renewal staff Austin, Ferguson Structural Engineering Laboratory (FSEL). The audit was conducted to suppotesting program.

The inspectors also conducted an in-(RCE) and corrective actions related to the identification of differential movement, or deformation, of the containment enclosure building (CEB). This condition is described in an NRC inspection report, dated August 25, 2015 (Agencywide Documents Access and Management System (ADAMS) Ascension No. ML15217A256). In addition, inspectors reviewed evaluations related to discrete cracks identified in below grade, internal walls in the RHR and containment spray (CS) equipment vault structure. This condition was previously described in an NRC inspection report dated August 5, 2014 (ADAMS Accession No. ML14212A458).

The inspectors assessed the problem identification threshold, operability and functionality assessments, extent of condition reviews, and the prioritization and timeliness of corrective actions to determine whether NextEra personnel were appropriately identifying, characterizing, and correcting problems associated with the ASR-compliance with the CAP procedure and 10 CFR 50, Appendix B requirements. The resident inspectors continued to conduct routine walk downs of Seabrook Station ASR-affected structures, focusing on the identification of any changes that have the potential for further degrading the functional performance of these structures or associated systems and components.

b. Findings and Observations

During the week of October 26, 2015, the NRC audit team observed the last planned large-scale specimen testing at FSEL, reviewed test program results and analyses completed, to date, and interviewed NextEra staff and their consultants. Audit team activities and conclusions are documented in an NRC audit report (ADAMS Accession No. ML15307A019) dated December 17, 2015. No significant observations or concerns were identified related to the conduct of testing to appropriate quality assurance criteria. NextEra staff planned to have the test data analyses completed by the end of 2015, in support of submitting to the NRC a license amendment request in 2016, to address an ASR-related non-conforming condition with the current licensing basis. NRC inspectors conducted in-office reviews of the root cause evaluation for the 3, dated March 17, 2015. CEB deformation, NextEra staff concluded that internal expansion (strain) produced by ASR in the CEB concrete (in-plane direction of the CEB shell) and ASR expansion in the backfill concrete, coincident with a unique building configuration, resulted in CEB deformation. Second, regarding NRC identification of this issue, NextEra concluded this was not identified by plant staff due to an organizational mindset that viewed conditions such as concrete cracks, water infiltration, and misalignment issues as acceptable and inconsequential. Additionally, the RCE identified that NextEra staff did not perform and document comprehensive evaluations of building conditions that could have potentially revealed more significant underlying conditions, such as localized deformation of the CEB. These NRC-identified performance deficiencies were previously dispositioned as non-cited violation (NCV) 2015002-01 and NCV 2015002-02 in NRC inspection report 05000443/2015002 (ADAMS Accession No. ML15217A256).

The inspectors determined NextEra corrective actions to address these problems included: 1) a revision to their design control procedures to require pozzolanic materials like fly ash or slag cement to be added to concrete mixes to prevent ASR in any new concrete structures; and, 2) the implementation of multiple training and program changes to correct the organizational mindset issues and strengthen individual responsibilities and accountability for implementation of the Seabrook Structures Monitoring Program. The inspectors concluded the RCE was reasonably thorough and utilized a cause and effect methodology that was appropriate to the problem statement.

HowNRC inspectors, and not plant staff, identified the presence of localized ASR-induced viewed conditions such as concrete cracks, water infiltration, and misalignment issues as acceptable and inconsequential. The inspectors concluded the RCE was reasonably thorough and utilized a cause and effect methodology that was appropriate to the problem statement. The planned and in-process organizational and program related corrective actions appeared appropriately focused on the identified causes of the problem. However, the inspectors concluded that the corrective actions, taken to date, to implement multiple training, program and oversight changes to correct the organizational mindset issues and strengthen individual responsibilities and accountability for implementation of the Seabrook Structures Monitoring Program have either not been implemented or are not yet effective and thus require additional management attention near-term. The inspectors noted that the CEB RCE referenced the results of a Finite Element Analysis (FEA) model of the CEB. The FEA and results were documented in FP 100985. The inASR expansion to assess the impact of expansion induced deformation on the structural performance of the CEB. The FEA evaluated CEB design capacity against assumed loading, based on ACI 318-71 criteria, including simulated loads associated with the as-deformed condition. As documented in FP 100985, the FEA model also simulated the impact of the external structural loading due to ASR expansion of the backfill concrete.

Based upon the review of the CEB structural assessment described in FP 100985 and the limited structural analysis of the RHR/CS vault documented in FP100903, the inspectors had multiple follow-up questions regarding the CEB and RHR/CS vault structural assessments and the open Immediate Operability Determinations and Prompt Operability Determinations (PODs) for these ASR-affected structures (reference AR 01664399, AR 01929460, AR 01977456, AR 02004749, and AR 02044627). The follow-up questions were developed via a collegial review by the Region 1 Senior Reactor Analyst and structural engineers from NRC Offices of Nuclear Reactor Regulation and Region 2, under the auspices of the Seabrook ASR Technical Team (ADAMS Accession No. ML14014A378). The questions were documented and shared with the NextEra staff on December 23, 2015 (ADAMS Accession No. review are planned for the first quarter of 2016 and will be documented in an NRC inspection report.

Following the guidance of IMC Structures Monitoring Program. Specifically, the structural evaluations, performed by contractors and accepted by NextEra staff via the FP process, included discussions that identified the potential to exceed limits in the applicable design code (ACI 318-71) for specific locations in the CEB and RHR/CS vault walls. The evaluations further recommended actions to determine whether this was the case. The inspectors noted that the Seabrook staff screened or reviewed these evaluations without documenting a justification in a revision or update to the open PODs for these structures. The additional information requested on December 23, 2015 is required for the inspectors to determine whether this issue involves a performance deficiency. As a result, the NRC opened an unresolved item (URI). Introductionimplementation of the Seabrook structures monitoring program and acceptance of evaluations via the FP and CAP.

Description.

Additional inspection is warranted to determine whether a performance FP 100903 for the RHR/CS vault condition. Specifically, further inspection is warranted to determine whether NextEra staff properly implemented the Seabrook structures monitoring program for the acceptance and review of structural evaluations potentially impacting the functionality of the CEB and RHR/CS vault, as currently documented in open PODs.
