SUMMARY

Watts Bar Nuclear Plant, Unit

This integrated inspection included aspects of engineering and construction activities performed by TVA associated with the Watts Bar Nuclear (WBN) Plant Unit construction project. This report covered a seven-week period of inspections in the areas of quality assurance (QA),

identification and resolution of construction problems, construction activities, pre-operational testing, and follow-up of other activities. The inspection program for Unit construction activities is described in NRC Inspection Manual Chapter 2517, "Watts Bar Unit Construction Inspection Program." Information regarding the WBN Unit Construction Project and NRC inspections can be found at http://www.nrc.gov/info-finder/reactor/wb/watts-bar.html. Inspection Results

• The NRC identified a severity level (SL) IV non-cited violation (NCV) of Code of Federal Regulations (CFR) 50, Appendix B, Criterion V, "Instructions, Procedures, and Drawings," for failure to follow procedures. Specifically, a fastener utilized to retain a plug internal to the number two steam generator (SG) was tightened outside of the approved work process by a job-site supervisor unfamiliar with the torque wrench's operation, such that the subsequent quality control verification step did not identify a fastener tightened in excess of the design torque value. The performance deficiency was considered more than minor in accordance with Inspection Manual Chapter (IMC)2517 because it represented an improper or uncontrolled work practice that, if left uncorrected, could impact the quality or safety of a safety-related structure, system, or component. The finding was determined to be of very low safety significance in accordance with Section 6.5 of the NRC Enforcement Policy because it is does not represent a breakdown in the QA process. The applicant issued problem evaluation report 800044, and the responsible contractor initiated nonconformance report 905601-01, to address the identified conditions. A procedural cross-cutting aspect was identified in the Work Practices component within the Human Performance area H.4(c). (Section C.1.2)

• The inspectors concluded that concerns pertaining to one Inspection Follow-up Item (IFI) have been appropriately addressed for WBN Unit 2. In addition, sufficient inspections have been completed to close out five inspection procedures (IP). These items are closed.

• Other areas inspected were adequate with no findings identified. These areas included QA; piping; mechanical systems and components; electrical systems and components; fire protection; pre-operational testing activities; various NRC inspection procedures; and refurbishment activities.

a. Inspection Scope

Background: An NRC assessment of this element of the construction project quality assurance program was documented in integrated inspection reports 05000391/2010610 Agencywide Document Access and Management Systems (ADAMS) accession number ML13035A201 and 05000391/2009602 ADAMS accession number ML091210420. The 05000391/2009602 report documented that the requirements for periodic review under inspection procedure 35060, 35960, and 35100 had been satisfactorily completed.

Inspection Activities: Related to the requirements of Appendix B Criterion 1, Organization, the inspectors interviewed the Senior Advisor for Tennessee Valley Authority (TVA) Quality Assurance and the Quality Assurance Manager for Bechtel, TVA's engineering, procurement, and construction contractor for Unit 2, to determine whether substantive changes had occurred to the organizational structure since the previous NRC inspection. The discussion also addressed changes in the following areas: quality assurance staffing, quality assurance policy, quality assurance procedures and the reporting mechanism to the corporate quality assurance organizations for both TVA and Bechtel.

Both TVA and Bechtel organizational charts were reviewed to determine whether any changes to the organizations since the last NRC inspection decreased the level of commitments for both quality assurance organizations and whether independence from cost and scheduling responsibilities was maintained. In addition, the inspectors interviewed quality assurance personnel to determine whether staffing levels were adequate for the scope of work. Training records were reviewed and evaluated to determine whether individuals had the proper experience and received appropriate training to perform quality assurance and control inspections on various types of construction activities for Unit 2.

The TVA and Bechtel's quality assurance manuals were reviewed by inspectors to determine if substantive policy changes had occurred. The review also evaluated whether the quality assurance manuals identified services such as engineering, procurement, and design activities and those organizations that had responsibilities to perform such activities.

Two Bechtel procedures and one TVA procedure were evaluated to determine whether revisions to the procedures followed the control process for procedure revisions and document control. In addition, one TVA and one Bechtel audit were reviewed to evaluate whether the reporting mechanism to each other's organization and their corporate quality assurance departments communicated deficiencies and trended areas to detect problems. In addition, the inspectors evaluated whether corrective actions taken had been communicated to corporate management when instances of unacceptable performance were identified.

Documents reviewed are listed in the attachment. The following inspection procedure sections applicable to Criterion I were inspected:

• IP 35060, Section 02.02

• IP 35100, Section 02.01

• IP 35960, Section 02.01

b. Observations and Findings

No findings were identified. The review of changes to the QA program and policy, and interviews with QA program management, identified that QA program changes have been implemented since the previous inspection of this area; however, none of the changes implemented resulted in reductions in the level of commitment for the applicant's and engineering, procurement, and construction contractor's QA programs. c. Conclusion Based upon the review of activities to implement requirements for organizational structure and interaction between TVA and Bechtel quality assurance organizations, the inspectors concluded that the activities related to the above sections of the inspection procedures conformed to the applicable regulatory requirements.

The inspection was completed to verify the pump was aligned in accordance with N3602, "Installation of Rotating Equipment," Rev. 3, the approved vendor manual specifications, and that M&TE was properly controlled and calibrated.

Documents reviewed are listed in the attachment.

b. Observations and Findings

The following severity level (SL) IV non-cited violation was identified.

Introduction:

The NRC identified a severity level (SL) IV non-cited violation (NCV) of 10 CFR 50, Appendix B, Criterion V, "Instructions, Procedures, and Drawings," for failure to follow procedures. Specifically, a fastener utilized to retain a plug internal to the number two SG was tightened outside of the approved work process by a job-site supervisor unfamiliar with the torque wrench's operation, such that the subsequent quality control verification step did not identify a fastener tightened in excess of the design torque value.

Description:

On October 24, 2013, inspectors reviewed ongoing work associated with the installation of a plug into the wrapper barrel of SG 2 as described in WO 115097433. This installation activity required QC to witness the torquing of the plug fastener to within a vendor specified range of 60 in-lbs to 80 in-lbs. In the course of the inspection, the inspectors observed personnel place a torque wrench on the plug fastener and torque the fastener without a QC or authorized nuclear inspector (ANI) being present to witness the actual torque applied. Additionally, no oversight was provided for this work by the QA organization. The inspectors observed personnel using the wrench beyond its set point of 80 in-lbs, resulting in over-torquing of the plug fastener. The type of torque wrench utilized did not capture the maximum torque value applied, leaving the fastener torqued to an unknown value.

The inspectors determined that the applicant's actions outside of approved work instructions were a performance deficiency. This performance deficiency was considered more than minor in accordance with Inspection Manual Chapter (IMC) 2517, Appendix C because it was similar to an example in IMC 0613, Appendix E "Examples of minor construction issues." Example 21 of IMC 0613, Appendix E represents a more than minor example where the licensee bypassed a QC holdpoint in a procedure and the QC inspection attribute could not be verified at a later point in the construction process. This example was similar to the performance deficiency identified because personnel were observed placing a torque wrench on the plug fastener and torqueing the fastener without QC or ANI present to witness the actual torque applied. Based on the applicant's initial assessment, it was determined that the as-installed condition of the plug could not be evaluated by engineering for acceptability because the actual torque value applied to the plug fastener could not be verified. Because the plug fastener could not be accepted as-is, it was replaced. The finding was determined to be of very low safety significance in accordance with Section 6.5 of the NRC Enforcement Policy because it is does not represent a breakdown in the QA process. The applicant issued PER 800044, and the responsible contractor initiated nonconformance report (NCR) 905601-01, to address the identified conditions.

The inspectors reviewed this finding against cross-cutting area components as described in Inspection Manual Chapter (IMC) 0310 "Components Within the Cross-Cutting Areas". The failure of the applicant to ensure supervisory and management oversight of work activities, including contractors, such that nuclear safety was supported reflected the procedural aspect of the Work Practices component within the Human Performance area H.4(c). This aspect applies, because without appropriate oversight present to observe the torquing of the fastener, the actual torque value could not be determined and therefore the plug was in an indeterminate condition.

Enforcement:

10 CFR 50, Appendix B, Criterion V, "Instructions, Procedures, and Drawings," requires, in part, that, "Activities affecting quality shall be prescribed by documented instructions, procedures, or drawings, of a type appropriate to the circumstances and shall be accomplished in accordance with these instructions, procedures, or drawings." Step 9.2.8.b of WO115097433, required that the plug be torqued within 60-80 in-lbs, and that QC shall witness the torque.

Contrary to the above, on October 24, 2013, the applicant failed to install a plug into the wrapper barrel of SG 2 in accordance with WO 115097433. Specifically, the NRC witnessed personnel applying excessive torque to the plug fastener outside of the work instruction. Additionally, QC was not present during the activity and failed to verify whether the actual torque value was within the specified torque range.

Because this was a SL IV violation and it was entered into the applicant's corrective action program as PER 800044, this violation is being treated as an NCV, consistent with Section 2.3.2 of the NRC Enforcement Policy. This violation is identified as NCV 05000391/2013609-01, "Over-Torquing of Steam Generator Plug Fastener."

c. Conclusions

With the exception of the above example, the observed foreign object removal process associated with the refurbishment of SG 2 and the NDE activities were completed in accordance with the approved procedures, and the records reviewed were in compliance the ASME B&VP code 1971 edition through 1973 summer addenda.

C.1.3 Piping - Piping Work Observation (Inspection Procedure 49063)

a. Inspection Scope

The inspectors observed safety-related piping hydrostatic tests for system 074, residual heat removal piping, and system 063, safety injection piping, that is cross connected to system 074. The hydrostatic test boundary included system 074 piping from 2-RVCV 24 miniflow piping through the main 2B residual heat removal (RHR) pump piping to 2-FVC 521. In addition, the hydrostatic test boundary included system 063 piping from 2-FCV 73 through the main 2B RHR pump piping to 2-FCV 521.

• Watched for abuse of installed instrumentation such as stepping or climbing on the instrumentation that could affect the calibration or ability to function;

• Listened for the public address system announcements to determine that blind spots did not exist; i.e., cannot be heard clearly enough to be understood;

• Construction work force authorized to perform activities on systems or equipment;

• Openings were controlled in previously cleaned or flushed systems or components. Verified that cleanliness controls established during flushing have not been invalidated; and

• Reviewed log books maintained by the test group to identify problems or plant activities that may be appropriate for additional follow-up; determine that deficiencies identified by individual engineers were entered on a controlled list In addition, the inspectors witnessed the performance of component test procedures GTE-04, "Coupled/Uncoupled Motor run-In Test," Rev. 3, for the 2B containment spray uncoupled motor run; and GTE-11, "Motor Operated Valve/Damper Test," Rev. 5, for 2-FVC 0153-B (MOVATs test). The inspections were completed to verify that the testing was conducted in accordance with approved procedures and to verify the adequacy of test program records and preliminary evaluation of test results. The inspectors performed the following activities associated with these test observations:

• All test personnel were on station and had the latest revision of the procedure;

• Plant systems were in service to support the test;

• Testing equipment was installed and within calibration;

• Testing was performed in accordance with the approved procedure;

• Testing events and discrepancies were properly documented;

• Testing was executed and coordinated properly;

• Data was properly collected; and

• Testing personnel were using approved drawings and vendor manuals In addition, the inspectors observed the test to verify that the overall test acceptance was met. The inspectors conducted a review with the responsible test engineer to assure that the preliminary test evaluation was consistent with the inspectors' observations. During the test, inspectors observed important data gathering activities to ensure the data was properly gathered and recorded. A post-test cursory review of the test data was performed to verify legibility, traceability, and permanence of the data sheet entries. The inspectors conducted interviews and reviewed training records for the test director involved in the pump decoupled motor run test to verify they had received appropriate training for performing the test in accordance with procedural requirements.

02.02 (Monthly Inspection Activities): During this inspection period, the inspectors reviewed the turnover package for the Unit 2 portion of the Essential Raw Cooling Water system (System 67) as part of Startup Manual Procedure (SMP) 4.0, "System Completion and Turnover," Rev.9, to verify jurisdiction controls were appropriate and applicant procedures were followed. Additionally, the inspectors reviewed the turnover package to ensure required preventative maintenance was incorporated into a schedule for accomplishment.

The inspectors reviewed maintenance plans on safety-related equipment, to determine if the maintenance was scheduled in accordance with developed procedures and that these procedures were adequate for the maintenance being performed. The maintenance had not been performed but the methodology was discussed with the Refurbishment and Preventative Maintenance Manager to determine how systems with completed preoperational testing would be protected.

Documents reviewed are listed in the attachment.

The inspectors determined that the applicant's test procedure was written in a manner consistent with the guidance of procedure SMP-8.0, "Watts Bar Nuclear Plant Unit 2 Administration of Preoperational Test Instructions," Rev. 9. A review of the revised test procedure should be performed to ensure that any of additional acceptance criteria is complete. IV. OTHER ACTIVITES OA.1.1 (Discussed) Generic Letter 2006-03: Potentially nonconforming HEMYC and MT fire barrier configurations; Bulletin No. 1992-01: Failure of Thermo-Lag 330 Fire Barrier System to Maintain Cabling in Wide Cable Trays and Small Conduits Free from Fire Damage; Bulletin No. 1992-01 (Supplement 1): Failure of Thermo-Lag 330 Fire Barrier System to Perform Its Specified Fire Endurance Function; Generic Letter 1992-08: Thermo-Lag 330-1 Fire Barriers (Inspection Procedure 35007)

a. Inspection Scope

Background: Generic Letter (GL) 2006-03 informed licensees of required actions to address issues related to electrical raceway fire barrier system (ERFBS) material that was installed and relied upon for separation and/or safe shutdown purposes to satisfy applicable regulatory requirements. GL 92-08 informed licensees of failures in fire barrier system endurance and ampacity derating tests, installation procedures, and as-built configuration discrepancies associated with the Thermal Science, Incorporated (TSI), St. Louis, Missouri, Thermo-Lag 330-1 ERFBS that was installed to protect safe shutdown capability. The NRC initiated a series of small scale fire tests for a sample of ERFBS and issued the results of the TU Electric and NRC fire tests in Bulletins 92-01,

"Failure of Thermo-Lag 330 Fire Barrier System to Maintain Cabling in Wide Cable Trays and Small Conduits Free form Fire Damage," June 24, 1992, and 92-01 Supplement 1,

"Failure of Thermo-Lag 330-1 Fire Barrier system to Perform its Specified Fire Endurance Function," August 28, 1992. NRC inspection report (IR) 05000391/20130615 (ADAMS accession number ML13162A775) describes additional background information, Unit 1 and Unit 2 corrective actions, and initial NRC inspection activities of the Unit 2 engineering design methodology, to address the ERFBS historical issues.

Inspection Activities: The inspectors reviewed the work procedures and observed the ERFBS thermo-lag 330-1 material installations and for conduits 2PLC584 and B2PLC585B to verify that the installation activities were completed in accordance with G-98, "Installation, Modification, and Maintenance of Electrical Raceway Fire Barrier Systems," revision 9 and the approved drawings.

The inspectors also reviewed ampacity de-rating, combustible loading, and seismic loading calculations to verify that the addition of the thermo-lag material to the conduits were included in the revised design analysis, were adequate and completed in accordance with the approved procedures. In addition, the inspectors reviewed the thermo-lag 330-1 material test reports to verify the material density and shear strength test results were in compliance with the design requirements.

Documents reviewed are listed in the attachment.

b. Observations and Findings

No findings were identified.

c. Conclusions

The thermo-lag fire barrier material installations were installed in accordance with the approved procedures, and the design controls were in place to incorporate the additional material with regards to the electrical ampacity, structural supports, and fire loading area. OA.1.2 (Discussed) Historical 10CFR21 Reviews (Inspection Procedure 92701)

a. Inspection Scope

The applicant committed to perform a review of historical 10 CFR Part 21 (Part 21) issues that were applicable to WBN Unit 1 for applicability and potential resolution for WBN Unit 2. The review process was captured in applicant procedure 25402-3DP-G04G-00501, "Historical Document Review Process" and subsequently expanded upon in applicant PER 494917. The procedural guidance utilizes a review of all issues documented in the applicant's historical database (Watts Bar Nuclear Plant Unit 2 Startup Integration Task Equipment List (WITEL)) and PER 494917 outlined the methodology the applicant planned to use to quantify, qualify, and subsequently resolve issues identified from historical Part 21's. The inspectors reviewed the procedure, assessed the methodology of the review, and performed an independent verification of the applicants historical Part 21's results to ensure that the review encompassed all applicable historical issues. Additionally, the inspectors held interviews with applicant staff to understand the rationale for screening historical Part 21's for applicability to WBN Unit 2.

b. Observations and Findings

Introduction:

The inspectors identified an Unresolved Item (URI) associated with the accuracy of the review of the historical documents contained in the applicant's WITEL database.

Description:

The review of PER 494917 revealed that the applicant's intention was to "obtain a listing of all 10CFR Part 21 issues applicable to Unit 1, perform a review for Unit 2 applicability, and assign the Unit 2 applicable 10CFR21 issues to the appropriate Unit 2 design discipline." The inspectors performed an independent sample of historical items in the WITEL database and identified additional WBN Unit 1 Part 21's which were not identified by the applicant as well as WBN Unit 2 applicable Part 21's with inadequate justification for closure for WBN Unit 2. Specifically, the inspectors reviewed the 11 items the applicant screened as applicable to WBN Unit 2 and, through additional searches within the WITEL database, identified the total population of potentially applicable items as approximately 46. Along with this disparity in population was the rationale for closure of some items that were classified as applicable. Because the applicant was not aware of these items, they had not been evaluated for applicability to Unit 2. In response to the observations within this URI, the applicant has issued PER 806990 to perform an additional review of the WITEL database for potentially applicable items to WBN Unit 2 and identify any of necessary corrective actions.

Further review is needed to address the issue of concern as defined by IMC 0612, "An issue of concern about which more information is required to determine (a) if a performance deficiency exists, (b) if the performance deficiency is More-than-Minor, or (c) if the issue of concern constitutes a violation. Such a matter may require additional information from the licensee or cannot be resolved without additional guidance, or clarification/interpretation of the existing guidance." The following items will be reviewed to address the URI:

1. Review the actions associated with PER 806990; 2. Perform an independent verification of the WITEL database screening for applicability to WBN Unit 2; 3. Evaluate the corrective actions associated with those items applicable to WBN Unit 2; and 4. Review/observe additional field work, as necessary This unresolved item is identified as URI 05000391/2013609-02, Potential Inadequate Corrective Actions for Historical Issues.

c. Conclusions

The inspectors could not draw a conclusion at the time of the inspection report period.

OA.1.3 (Discussed) Temporary Instruction 2515/120, Inspection of Implementation of Station Blackout Rule Multi-Plant Action Item A-22 (Temporary Instruction 2515/120)

a. Inspection Scope

Background: On July 21, 1988, the NRC amended 10 CFR Part 50 to include 10 CFR 50.63, "Loss of All Alternating Current Power," known as the station blackout (SBO) rule.

The SBO rule requires that each light-water-cooled nuclear power plant be able to withstand and recover from an SBO of a specified duration. The SBO rule also requires licensees to submit information as defined in 10 CFR 50.63 and to provide a plan and schedule for conformance to the SBO rule. The NRC staff issued a safety evaluation (SE), dated March 18, 1993, and a supplemental SE, dated September 9, 1993 (ADAMS Accession Nos. ML073200313 and ML073200358, respectively), which concluded that TVA's response to the SBO rule was acceptable for both WBN Unit 1 and Unit 2. Although the staff issued an SE for both units, TVA did not seek an operating license for Unit 2 at that time. The NRC staff requested that TVA update or validate the original information or provide a new response addressing how WBN Unit 2 meets the SBO rule.

The NRC staff issued SE report as supplement 22 to NUREG0847 (ADAMS Accession No. ML110390197), dated January 2011, addressing updated information regarding TVA's implementation of the SBO rule.

The purpose of Temporary Instruction (TI) 2515/120 was to verify through inspection the adequacy of applicant programs, procedures, training, equipment and systems, and supporting documentation for implementing the SBO rule. Inspection Activities: The inspectors conducted walkdowns, reviewed drawings, procedures, and calculations, and performed inspections as appropriate for selected plant areas of importance to the SBO rule. Specifically, the inspectors performed the following:

• Reviewed the emergency diesel generator (EDG) battery sizing calculation, WBNEEBMSTI110062, Rev. 28, to verify that at least two field flashings were considered in the battery sizing calculation;

• Reviewed AOI-40 to ensure one EDG start attempt was reserved for the end of the SBO coping period;

• Reviewed condensate storage tank (CST) drawings to verify CST capacity is consistent with that discussed in the SE and that no credit is taken for the volume below the suction connections;

• Reviewed 0-AOI-8, Rev. 0, to verify implementation of site-specific procedures for preparing the plant for severe weather conditions to reduce the likelihood and consequences of a loss of offsite power (LOOP) and to reduce the overall risk of an SBO event;

• Reviewed AOI-40, to verify procedural guidance for restoration of shutdown alternating current power via the EDGs or backfeed from the 500-kilivolt system;

• Reviewed the applicant's SBO coping evaluation, EPMMA041592, Rev. 19, to verify TVA addressed the effects of a loss of ventilation during an SBO event at WBN Unit 2; and

• Reviewed NETP-100, Emergency Diesel Generator Reliability Program, Rev. 3, to verify that Watts Bar utilized an EDG target reliability of 0.975 and that current reliability data indicates that the EDGs were meeting that goal. Documents reviewed are listed in the Attachment.

b. Observations and Findings

No findings of significance were identified.

c. Conclusions

To date, the applicant's proposed actions taken to meet the requirements of the SBO rule are acceptable. However, modifications related to the Unit 2 SBO requirements were in progress at the time of inspection and specific procedures for coping with an SBO event had not been issued for Unit 2. Additional inspection will be required to close TI 2515/120.

OA.1.4 (Discussed) Bulletin 88-09: Thimble Tube Thinning in Westinghouse Reactors (IP 35007)

a. Inspection Scope

Background: TVA committed by letter dated March 11, 1994 (ADAMS Accession Number ML073241193), for both units to establish a program and to inspect the thimble tubes during the first refueling outage. This was established for Unit 1 by DCN 39481 and through revision of Maintenance Instruction MI-94.004 to perform eddy current testing every refueling outage. This item was identified as closed in SER 16 (ADAMS Accession Number ML073450552), Appendix EE, page 10. TVA tracked this item in its Framework Letter ADAMS Accession Number ML110210486) and Status of Generic Communications (Enclosure 3) for Unit 2 with a status of "CI," indicating they considered this item closed awaiting implementation. However, as restart for Unit 2 proceeded, TVA, in conjunction with its vendor Westinghouse, developed EDCR 52321. This EDCR was issued to install the Westinghouse In-Core Information, Surveillance, and Engineering (WINCISE) system, which employs a fixed in-core detector as opposed to the traditional moveable core detector utilized on Unit 1. Westinghouse has analyzed the new system to exhibit essentially no wear due to vibrations through its higher natural frequency and lower vibration amplitude. Additionally, Westinghouse notes that the new In-Core Instrument Thimble Assemblies (IITAs) rely on a Seal Table Swagelok fitting to ensure that even if there is a full penetration wear hole in the IITA outer sheath, there would be no direct loss of reactor coolant pressure boundary integrity into the containment building environment outside of the primary sump recirculation loop. Consequently the applicant has determined that issues addressed in NRC Bulletin (BL) 88-09 do not apply to the WINCISE system.

Inspection Activities: To address this issue for Unit 2, the inspectors performed the following:

• Reviewed the applicant's final closure package

• Interviewed engineering and management personnel for both TVA and Westinghouse familiar with the WINCISE system design and installation

• Reviewed proprietary design drawings

• Reviewed system literature

b. Observations and Findings

No findings were identified.

c. Conclusions

Based on a review of the applicant's final closure package, the inspectors concluded that the applicant has altered the design to a fixed-probe monitoring system. As these systems were not subject to a bulletin for thinning concerns, the applicant's approach that the bulletin is no longer valid appears to have merit. However, additional review of future documentation may be performed to fully understand the applicability of the BL. OA.1.5 (Closed) Inspector Follow-up Item 391/86 05: Installation of Springnuts in Unistrut (Inspection Procedure 52053)

a. Inspection Scope

Background: As documented in Inspection Report Numbers 50-390/86-14 and 50-391/86-14 (ADAMS accession number ML072500283), during a visual inspection of rework activities on instrumentation lines, inspectors noted that instrumentation devices were being fastened to supports with unistrut and springnuts. Springnuts are designed with a recessed knurled groove which fits into a lip on the unistrut and provides a locking feature to prevent slippage. At that time the inspector noted that several installed springnuts failed to be properly seated in the lip of the unistrut. Based on the inspector's observations, engineering personnel performed a walkdown and identified other areas where similar conditions existed. In 1989, the licensee initiated Construction Deficiency Report (CDR) 50-390/89-11 for Unit 1 to identify a significant deficiency pertaining to hardware found to be damaged, loose, and/or missing subsequent to QC inspection and acceptance. CDR 50-390/89-11 was closed in Inspection Report Numbers 50-390/94-35 and 50-391/94-35. A CDR was never issued for Unit 2 and IFI 391/86 05 remained open.

Inspection Activities: In order to close IFI 391/86 05 for Unit 2, inspectors performed a review the licensee's walkdown procedures used for documenting existing conditions of Seismic Category I and I(L) piping and pipe supports. These procedures were used for documenting existing conditions prior to the re-start of Unit 2 construction and were reviewed to ensure critical aspects related to the installation of springnuts in unistrut were properly addressed. Inspectors also reviewed current procedures and QC inspection attributes to ensure that the previously identified conditions were properly addressed. In addition, QC inspectors were interviewed to ensure that they understood the installation and inspection requirements. Finally, inspectors performed an independent walkdown of portions of the Residual Heat Removal, Containment Spray, Component Cooling Water and Safety Injection Systems to ensure that there were no improperly installed springnuts identified.

b. Observations and Findings

No findings of significance were identified.

c. Conclusions

Based on these actions, the inspectors determined that IFI 391/86 05 is closed. V. MANAGEMENT MEETINGS X1 Exit Meeting Summary An exit meeting was conducted on November 21, 2013, to present inspection results to Mr. Hruby and other members of your staff. The inspectors identified that no proprietary information had been received during the inspection and none would be used in the inspection report. The applicant acknowledged the observations and provided no dissenting comments.
