REPORT DETAILS

Summary of Plant Status

During the inspection period covered by this report, TVA performed construction completion activities on safety-related systems and continued engineering design activities of the Watts Bar Nuclear (WBN) Plant, Unit 2.

I. QUALITY ASSURANCE PROGRAM Q.1 Quality Assurance (QA) Oversight Activities Q.1.1 Identification and Resolution of Construction Problems (Inspection Procedure [IP] 35007)

a. Inspection Scope

The inspectors continued to review problem evaluation reports (PERs), as part of the applicant's corrective action program, to verify that issues being identified under the corrective action program were being properly identified, addressed, and resolved by the applicant. The inspectors reviewed several PERs also discussed in Section C.1.2 Structural Concrete - Work Observation (IP 46053), of this report.

The inspectors also identified a number of final closure packages, which had been provided by the applicant and utilized by the NRC, to support closure of historic construction concerns. For the samples selected, the inspectors reviewed the applicant's final closure packages and supporting documentation, interviewed personnel knowledgeable of the issue, and performed walkdowns of physical plant changes. For six items that had been closed by the NRC prior to the issuance of a final closure package, the inspectors reviewed the applicant's final closure packages to ensure that actions previously identified by the applicant were properly translated into engineering and physical plant changes. Additionally, the inspectors reviewed 10 final item closure packages, which had been revised after closure by NRC staff, to verify that changes within the revision did not alter or invalidate previous conclusions. Documents reviewed are listed in the Attachment.

b. Observations and Findings

No findings were identified. The inspectors identified that most changes, to the closure packages reviewed, were minor administrative changes or increased support documentation as a result of the applicant's effort to provide for a more complete final closure package.

c. Conclusions

The issues identified in the PERs reviewed were adequately identified, addressed, and resolved.

Q.1.2 Safety Conscious Work Environment (IP 35007)

a. Inspection Scope

C.1.11 (Closed) Radiographic Examination Procedure Review/Work Observation/Record Review (IP 57090)

a. Inspection Scope

Background: A review of the historical inspection activities associated with IP 57090, as noted in IIR 050000391/2009602 (ADAMS Accession No. ML091210420), indicated that the requirements of IP 57090 had been met; however, the IP was published late in the original construction effort and many requirements were previously inspected in welding IPs. The intent of the inspection efforts had been to ensure that new construction activities (2008 - present) were performed in compliance with procedural and regulatory requirements. While no requirements were required, many of the original IP 57090 attributes were re-inspected for new work. These inspection efforts and the applicable IP sections can be found in the following IIRs:

• Section 02.01 - IIR 2010604 (ADAMS Accession No. ML103060240);

• Section 02.02 - IIR 2010605 (ADAMS Accession No. ML110410680), 2012609 (ADAMS Accession No. ML12356A073); and

• Section 02.03 - IIR 2009602 (ADAMS Accession No. ML091210420), 2009605 (ADAMS Accession No. ML100290703), 2010602 (ADAMS Accession No. ML101230144), 2010604 (ADAMS Accession No. ML103060240), 2010605 (ADAMS Accession No. ML110410680) (Section 02.03d -Digital radiographic images have not been used by the applicant or its contractors to date.) Inspection Activities: For the current inspection period, the inspectors reviewed radiographic film to determine whether the radiographic quality was in accordance with applicable procedure and ASME B&PV Code 1971 edition through 1973 addenda requirements. Specifically, the inspectors reviewed three radiographic films of the welds mentioned below for the following:

• Penetrameter type, size, and placement;

• Penetrameter sensitivity;

• Film density;

• Film identification;

• Film quality; and

• Weld coverage. The inspectors reviewed radiographic film for the following welds:

• Weld# 2-062A-D013-8E, WO# 09-952053-003, CVCS Flange to Pipe (one film)

• Weld# 2-062B-D139-35, WO# 09-951671-003, CVCS Pipe to Fitting (two films) The inspectors inspected radiographic film interpretation equipment to verify the equipment was calibrated. The inspectors also reviewed four personnel qualification records (radiographic testing (RT) examination) to verify conformance with the requirements of the contractor's written practice. The inspectors reviewed qualification records of inspection personnel to verify that they properly reflected the employer's names, persons certified, activities qualified to perform, effective period of certifications, proper signatures, basis, and annual vision acuity and periodic recertifications.

Documents reviewed are listed in the Attachment. The following samples were inspected:

• IP 57090 02.03 - one sample (2.03.a - 3 samples, 2.03.b - 4 samples)

b. Observations and Findings

No findings were identified.

c. Conclusions

The observed radiographic examination records met the applicant's procedural and ASME Code requirements. The processing of the radiographic film was conducted in accordance with procedure requirements. The radiographic personnel were certified in accordance with procedure and SNT-TC-1A requirements.

Based on the review of historical inspection activities and subsequent inspection of new work activities, this IP is considered closed; however, if major changes to the applicant's instructions and procedures are identified through observation of future work activities (including the use of digitized RT film), the inspectors will inspect those as necessary to satisfy the requirements in this procedure.

C.1.12 In-Service Inspection (ISI) - Review of Program (IP 73051), and ISI Inspection - Review of Procedures (IP 73052)

a. Inspection Scope

The inspectors reviewed the most recent revision (Rev.7) of the "Preservice Inspection Program Plan, Watts Bar Nuclear Plant Unit 2," and conducted interviews with the PSI program manager and PSI coordinator to ensure compliance with the requirements of ASME Section XI (2001 edition through the 2003 addenda), 10 CFR 50.55a, and additional commitments made to the NRC. Portions of the PSI program continued to be developed; for example, ASME Section XI, subsection IWL examinations for the containment vessel, and subsection IWF for supports; and were, therefore, unavailable for inspection. These items were also mentioned in Safety Evaluation Report (SER) as open item number 70, reviewed by NRC's Office of Nuclear Reactor Regulation (NRR) on February 2011 (ADAMS Accession No. ML11206A499).

Additionally, the inspectors reviewed "Preservice Inspection Program Plan, Watts Bar Nuclear Plant Unit 2," Rev. 7, to ensure compliance with ASME Section XI 2001 Edition through 2003 addenda. The PSI program is currently being revised, with each revision defining the welds to be examined for additional ASME Section XI examination categories. Examination categories with undefined weld populations for examination included B-K, C-A, C-B, C-C, C-D, C-F-1, C-F-2, C-G, D-A, F-A, snubbers (IWF-5000),

and containment (IWE-2000). The inspectors reviewed the results of the Authorized Nuclear Inspector (ANI) review of "Preservice Inspection Program Plan, Watts Bar Nuclear Plant Unit 2," Rev. 5, to understand the intent of the open items and completeness of the plan. The inspectors verified that "Preservice Inspection Program Plan, Watts Bar Nuclear Plant Unit 2," Rev. 7, was reviewed by appropriate applicant staff. Documents reviewed are listed in the Attachment.

b. Observations and Findings

No findings were identified. The inspectors determined that the applicant had established adequate procedures to implement the PSI requirements described in their PSI program plan; however, the inspectors noted that the PSI program plan had yet to implement all the PSI requirements required by ASME Section XI and 10 CFR 50.55a.

The inspectors confirmed that the applicant had not performed any work activities associated with the following programs:

• System leakage tests;

• IWF-5000 snubber inspections; and

• IWE and IWL inspections and tests.

c. Conclusions

The applicant's PSI program plan complied with ASME Section XI Code 2001 edition through 2003 Addenda.

The applicant's program for requalification training of personnel, anchor bolt re-training, and hanger training workshops were adequate for the current level of construction activities being performed.

IV. OTHER ACTIVITES OA.1.1 (Discussed) Construction Deficiency Report (CDR) 391/91-31: Use of Non-Dedicated Commercial Grade Electrical Devices in Safety-Related Applications (IP 35007)

a. Inspection Scope

Background: The deficiency was initially reported to the NRC on June 28, 1991, as significant corrective action report (SCAR) WBP890634SCA in accordance with 10 CFR 50.55(e). The issue was documented as CDR 390/91-31 for Unit 1 and CDR 391/91-31 for Unit 2.

The CDR dealt with the seismic qualification program for instrumentation and electrical equipment at WBN based on the requirements of Institute of Electrical and Electronics Engineers (IEEE)-344, "IEEE Recommended Practice for Seismic Qualification for Class 1E Equipment for Nuclear Power Generating Stations." Specifically, seismic sensitive electrically active (SSEA) devices were released from inventory for safety-related applications and were not procured or qualified to IEEE-344. These incidents occurred between February 1984 and January 1989.

The deficiency involved problems associated with replacement item procurement policies, procedures, and practices that did not adequately prescribe/control engineering involvement in the procurement process.

The applicant implemented the replacement items program (RIP) corrective action program (CAP) which committed, in part, to a review of inventory and installed SSEA commercial grade QA level II devices. The SSEA review consisted of 416 items in which 56 cases were determined as not satisfying IEEE-344 requirements. TVA corrective actions for Unit 1 included the replacement or an engineering disposition for the applicable installed equipment. After a review of the adequacy and effectiveness of root cause determination, extent of condition, corrective actions, recurrence controls, proper closure, and a review of the RIP CAP for Unit 1, the inspectors determined that CDR 390/91-31 was adequately resolved for Unit 1 as documented in NRC Inspection Report (IR) 50-390/94-66 (ADAMS Accession No. ML072980640) and 50-390/94-201 (ADAMS Accession No. ML072750699).

The SSEA review for Unit 1 included Unit 2 components. One component exception was noted during the review that did not meet the IEEE-344 requirements. The corrective actions for Unit 2 were documented in PER 144235. Unit 2 solid state protection system (SSPS) Train B, Midtex 156-14T300 relay K201 was identified as not meeting the requirements of IEEE-344. The relay is planned to be replaced with Westinghouse relay 2384A28H01 by WO 113314474. After a review of the Unit 2 RIP CAP, the inspectors determined the CAP was adequately implemented for Unit 2 as documented in NRC IIR 05000391/2010605 (ADAMS Accession No. ML110410680).

Remaining Unit 2 applicant actions:

• Install the K201 relay, WO 113314474; and

• Close CDR 391/91-31 and provide a final closure package to the NRC Inspection Activities: To address Unit 2 actions the inspectors performed the following:

• Reviewed PER 144235 to verify the corrective actions were implemented for Unit 2;

• Reviewed engineering closure documentation for CDR 391/91-31, dated March 29, 2012, to verify that the applicant's closure methodology adequately addressed the concern of the CDR;

• Reviewed certificate of conformance for Westinghouse SSPS Start-Up Kit, Train B, April 6, 2010, to verify the relay was purchased by a qualified vendor; and

• Reviewed Westinghouse Technical Bulletin TB 2 for SSPS Relays, January 6, 2004 and reviewed TVA WO 09-954267-001, Train B Master Relay Data Sheets, June 21, 2010, to verify that the components noted in the technical bulletin were identified by the applicant.

b. Observations and Findings

No findings were identified.

c. Conclusions

The corrective actions in place were adequate. Additional inspection activities are still planned prior to closure of CDR 50-391/91-31. Specifically, the inspectors plan to review the implementation of WO 113314474.

OA.1.2 (Discussed) CDR 391/82-80: Lack of Qualification of EDS Nuclear Incorporated (EDS) Embedment Plates (IP 35007)

a. Inspection Scope

Background: The deficiency was initially reported to the NRC on December 2, 1982, as non-conforming report (NCR) WBN CEB 8217 in accordance with 10 CFR 50.55(e). The issue was documented as CDR 390/82-84 for Unit 1 and CDR 391/82-80 for Unit 2.

The CDR concerned the lack of qualification for embedment plates. In 1978, EDS notified TVA by letter of the completion of their verification effort for TVA support embedment plates having EDS-designed pipe support loads. Several supports were identified in 1981, for the reactor coolant system (RCS) and the CCS piping at Watts Bar Nuclear Plant, which exceeded the allowable loads provided to EDS by TVA. TVA had already approved the EDS drawings and had issued them to its construction forces before the receipt of the vendor analysis was completed. Revised EDS support designs had been incorporated into the plant design under engineering change notice (ECN)-

2958.

The deficiency involved a failure by TVA design personnel to either understand or comply with the directions of TVA's Division of Engineering design engineering procedure 1.26, "Nonconformance Reporting and Handling by EN DES," which was in effect at that time.

The applicant analyzed the embedded plates that EDS had indicated as being overloaded and provided engineering justification for the design or modification of the embedment plates to reduce the plate stresses and anchor loads. Revised EDS support designs had been incorporated into the plant design under ECNs 2958 and 4241. After interviews with responsible applicant representatives and a review of the completed corrective actions for Unit 1, the inspectors determined that CDR 390/82-84 was adequately resolved for Unit 1 as documented in NRC IR 50-390/84-39 (ADAMS Accession No. ML082390462).

The review for Unit 2 associated with NCR WBN CEB 8217 required instrument support 2 A600 18 (47A600 18) to be installed in accordance with ECN 2958. Unit 2 addressed the corrective actions in PER 144186. TVA design engineering determined that support 2 A600 18 is no longer required as per calculation 290106, Rev. 2. Remaining Unit 2 applicant actions:

• Remove support 2 A600 18, WO 113775314; and

• Close CDR 391/82-80 and provide a final closure package to the NRC Inspection Activities: To address Unit 2 actions the inspectors performed the following:

• Reviewed PER 144186 to verify the corrective actions were implemented for Unit 2;

• Reviewed engineering closure documentation for CDR 391/82-80, dated November 28, 2011, to verify that the applicant's closure methodology adequately addressed the concern of the CDR;

• Interviewed design engineers and reviewed design calculation 290106, Rev. 2, to verify the adequacy of the engineering analysis; and

• Reviewed engineering document construction release (EDCR) 54251, which included DRAs 54251-205 and 206, to verify the design change included the removal of support structure 2 A600 18 (47A600 18)

b. Observations and Findings

No findings were identified.

c. Conclusions

The corrective actions in place are adequate. Additional inspection activities are planned prior to closure of CDR 50-391/82-80. Specifically, the inspectors plan to review the implementation of WO 113775314.

OA.1.3 (Discussed) CDR 391/89-06: Inadequate Qualifications for Cable Tray Supports and Fittings (IP 35007)

a. Inspection Scope

Background: The deficiency was initially reported to the NRC on June 22, 1989, as WBP 880040 and 880041 in accordance with 10 CFR 50.55(e). The issue was documented as CDR 390/89-06 for Unit 1 and CDR 391/89-06 for Unit 2.

The CDR concerned cable tray and supports that were not properly qualified for the as-built plant and the as-installed configuration of cable trays that did not match the design drawings.

The deficiency involved problems associated with three programmatic deficiencies as noted in the CAP plan for the cable tray and cable tray supports. The deficiencies included a lack of documented design qualification for cable tray hardware, installed configurations not complying with design output documents, and a lack of documentation to verify previous re-inspections. The applicant implemented the cable trays and cable tray supports CAP to correct the deficiencies for both Unit 1 and Unit 2. Unit 1 completed the following actions:

1) performed a design basis review and upgrade of the cable tray support documentation; 2) completed an evaluation of cable trays for structural integrity; 3) revised WB-DC 21.1, the design basis document for cable trays and tray supports; 4) verified the adequate thread engagement for bolting of tray fittings and hardware; 5) revised appropriate procedures to include installation, QA, and maintenance requirements; and 6) revised procedures to assure that design documents qualify cable tray hardware, the installed configuration complies with the design output, and re-inspections were properly documented. After a review of the adequacy and effectiveness of the corrective actions, a review of the cable trays and cable tray supports CAP for Unit 1, and inspections of the QA records associated with cable supports and cable tray supports, the inspectors determined that CDR 390/89-06 was adequately resolved for Unit 1 as documented in NRC IRs 50-390/94-64 (ADAMS Accession No. ML072980741), 50-390/95-69 (ADAMS Accession No. ML072610762), and 50-390/93-78 (ADAMS Accession No. ML072851292).

The corrective actions for Unit 2 were documented in PER 143986. As part of the inspections for the Unit 2 cable supports and cable tray supports CAP, the inspectors reviewed the applicant's final closure package for the CAP. The inspectors concluded that reasonable assurance exists that the programmatic aspects of the CAP, related to cable tray supports, had been adequately implemented and the inspectors were able to verify that appropriate actions had bounded and grouped cable trays and had properly identified deficiencies. The inspectors determined that further inspection would be needed to verify that work has been adequately performed to physically resolve the cable tray deficiencies identified by the CAP as documented in NRC IIR 05000391/2012602 (ADAMS Accession No. ML12087A324).

Remaining Unit 2 applicant actions:

• Implement design change packages EDCR 52934, 55045, and 55231; and

• Close CDR 391/89-06 and provide a final closure package to the NRC Inspection Activities: To address Unit 2 actions the inspectors performed the following:

• Reviewed PER 143986 to verify the corrective actions were implemented for Unit 2;

• Reviewed engineering closure documentation for CDR 391/89-06, dated January 19, 2012, to verify that the applicant's closure methodology adequately addressed the concern of the CDR; and

• Reviewed WB-D 21.1, "Design Criteria Document, Category I Cable Tray Supports", Rev. 10, to verify the design criteria included clearly defined structural requirements for cable trays.

b. Observations and Findings

No findings were identified.

c. Conclusion The corrective actions in place are adequate. Additional inspection activities are planned prior to closure of CDR 391/89-06. Specifically, the inspectors plan to review the WO implementation of EDCRs 52934, 55045, and 55231.

OA.1.4 (Closed) Supplemental Safety Evaluation Report (SSER) Appendix HH, Open Item 50, Refurbishment Inspection Commitment, Anchor Bolt Documentation and Pull Test (IP 46071)

a. Inspection Scope

Background: A letter from the NRC to the applicant dated July 2, 2010, stated that inspectors would follow up on pull tests for anchor bolts where historical records could not be retrieved. In addition, the applicant had previously stated that approximately five percent of the anchor bolts did not have QC documentation; however, at the time of the NRR review, none of the pull tests had been performed nor had all the QC documentation been retrieved. To resolve the NRC staff's comments, the applicant stated that if the pull test did not show that the anchor had adequate capacity, the anchor would be replaced.

Subsequent to the letter, the applicant had retrieved most of the QC documentation for anchor bolts which resulted in a population significantly less than the five percent as noted above.

In the fall of 2012, NRC inspectors documented their review and inspection of this item in Section OA.1.4 of NRC IIR 05000391/2012605 (ADAMS Accession No.

ML12319A368) and concluded TVA planned issuance of a revised letter reflecting actions taken to date. The inspection report also stated that the item would remain open pending a review of TVA's response. On January 24, 2013, TVA issued a letter to the NRC documenting the revised method to verify proper installation of existing concrete anchor bolts for safety-related pipe supports in those instances where pull test documentation could not be located. The letter stated that, for the hanger analysis and updated program (HAAUP) CAP, if QC pull test records are available, the documentation would be referenced in the support calculation. If the pull test documentation was not available, the support would be modified to replace existing anchors with wedge bolt or undercut anchors, including appropriate inspection and documentation. Furthermore, the letter stated a similar approach for instrumentation and components and sense line supports, with the exception that if the pull test record could not be located, a pull test would be performed for at least the design load times a safety factor of five. And, if the test failed, the anchor bolts would be replaced.

Inspection Activities: The inspectors reviewed the letter dated January 14, 2013, submitted by TVA revising their method for verifying proper installation of existing concrete anchor bolts for safety-related pipe supports. The inspectors had previously verified implementation of these actions as noted in NRC IIRs 05000391/2012605 (ADAMS Accession No. ML12319A368), 05000391/2011605 (ADAMS Accession No.

ML112201418), 05000391/2011607 (ADAMS Accession No. ML112730197),

05000391/2011608 (ADAMS Accession No. ML11311A082), and 05000391/2011609 (ADAMS Accession No. ML11350A229) which documented the replacement of self-drilling expansion shell (SSD) anchor bolt with wedge bolts. In addition, the inspectors conducted the review to verify that actions taken to date were consistent with those outlined in the January 2013 submittal. Documents reviewed are listed in the

.

b. Observations and Findings

No findings were identified.

c. Conclusions

The inspectors determined that actions inspected were performed by the applicant in accordance with their procedures and regulatory requirements. As a result, SSER Appendix HH Item 50 is closed.

OA.1.5 (Closed) CDR 50-391/93-05, Inappropriate Selection of Valve for Use as a Throttle Valve in the Safety Injection System (IP 35007)

a. Inspection Scope

Background: This issue involved the installation of 12 globe valves for throttling in the safety injection system in lieu of the needle valves required by the drawings on Unit 1. This issue was previously inspected and documented in NRC IIR 05000391/2012604 (ADAMS Accession No. ML12167A212), Section OA.1.1. During the inspection, the inspectors determined that the applicant's actions to replace the valves on Unit 2 were acceptable. This item was left open pending observation of field work.

Inspection Activities: During this inspection the inspectors observed four newly installed valves in the plant and reviewed WOs associated with the replacements to ensure field work was planned and was being tracked.

b. Observations and Findings

No findings were identified.

c. Conclusions

The applicant's actions were considered acceptable; therefore, CDR 50-391/93-05 is closed.

OA.1.6 (Closed) CDR 50-391/87-03, Potential for Valve Failure due to Key Loss (IP 35007)

a. Inspection Scope

Background: This item involved the potential for the valve stem and actuator yoke to become disengaged on quarter-turn valves. The potential scope included air-actuated butterfly valves where the valve actuator was installed below horizontal. This issue was described in NRC Information Notice 85-67, "Valve-Shaft-To-Actuator Key may Fall Out of Place when Mounted Below Horizontal Axis." This item was closed for Unit 1 in NRC IR 05000390, 391/90-27(ADAMS Accession No. ML072610322), Section 8.f.

Inspection Activities: The inspectors reviewed the documentation contained in the applicant's engineering complete package, which included the historic NRC documentation, the Unit 2 evaluation, the applicable Unit 2 EDCR, the list of affected valves, and the proposed corrective actions, to determine the applicant's corrective actions associated with this issue. In addition, the inspectors reviewed WOs associated with field work. Specifically, WOs 08-952680-000, 08-952677-000, 08-952648-000, 08-952646-000, and 11245505B, associated with 8 of the 11 affected valves, to verify the work being performed was consistent with the guidance documents. The inspectors also observed two of the installed valves, 2-FCV 0015B and 2-FCV 0037, to verify actuator physical orientation.

b. Observations and Findings

No findings were identified. The applicant determined that certain valves supplied by Posi-Seal International, Inc., were potentially affected by the problem and decided to install retention rings for those with actuators mounted at or below the horizontal plane. This was similar to the Unit 1 actions. The records showed that retention rings were appropriately installed for those valves mounted at or below horizontal. The applicant had completed most of the field work and remaining field work was being tracked.

c. Conclusions

The applicant's actions were considered acceptable; therefore, CDR 50-391/87-03 is closed.

OA.1.7 (Closed)Bulletin 88-08 and 88-08, Supplement 1, Thermal Stresses in Piping Connected to Reactor Coolant System (IP 92717)

a. Inspection Scope

Background: This item required applicant's to evaluate the potential for reactor coolant system leakage from stagnant lines due to thermal stresses. This item was previously inspected and documented in NRC IIR 05000391/2012607 (ADAMS Accession No.

ML12276A028). During that inspection the inspectors determined the applicant had credited the original bulletin (BL) response for intended actions which was not correct. In addition, the applicant's analysis appeared to imply use of an updated industry guide which had not been endorsed by the NRC.

Inspection Activities: During this inspection, the inspectors reviewed the applicant's revised intended actions contained in the applicant's update to the Regulatory Framework letter dated January 17, 2013, and reviewed applicant's procedure 2-TI-305, "Acoustic Monitoring to Detect Leakage Through 2-FCV 25 and 26," Rev. 0. In addition, the inspectors reviewed additional documentation contained in calculation 25402 V1B-WA42-00001-002, "MRP-146 Assessment of Normally Stagnant Non-Isolable Branch Lines," Rev. 1.

b. Observations and Findings

No findings were identified. The applicant had established actions to monitor leakage similar to Unit 1, that were in accordance with the latest approved guidance.

c. Conclusions

The applicant's actions were considered acceptable; therefore, BL 88-08 and 88-08 Supplement 1 are closed.

OA.1.8 (Closed) Reactor Coolant System Dissimilar Metal Butt Welds (Temporary Instruction 2515/172, Rev. 1)

a. Inspection Scope

Background: Temporary Instruction (TI)-2515/172 Rev. 1 expired on June 30, 2011, and the associated commitments of Materials Reliability Program (MRP) -139, "Primary System Piping Butt Weld Inspection and Evaluation Guidelines," July 2005, were captured in 10 CFR 50.55a(g)(6)(ii)(F) along with the associated ASME Section XI code case N

1. All inspection activities for Watts Bar 2 associated with the TI have been

completed with the exception of Section 03.06, "Inservice Inspection Program." The program requirements of Section 03.06 refer to MRP-139 which has been superseded by N

1. The new program requirements of N

1 will be incorporated into the applicant's ISI program following operations. Previous inspection activities associated with TI-2515/172 Rev. 1 can be found in IIR 2010604 (ADAMS Accession No.

ML103060240), 2010605 (ADAMS Accession No. ML110410680), and 2011608 (ADAMS Accession No. ML11311A082).

Inspection Activities: The inspectors discussed the future requirements of ASME Section XI code case N 1 with responsible applicant staff to verify the applicant's understanding of the code case.

b. Observation and Findings No findings were identified.

c. Conclusions

Based on the review of previous inspection activities, consideration of the fact that NRR has closed TI-2515/172 Rev 1 and the requirements have transitioned to 10 CFR 50.55a(g)(6)(ii)(F), and that those requirements will be inspected under IMC 2515 IP 71111.08, "Inservice Inspection Activities," TI-2515/172 Rev.1 is considered closed.

V. MANAGEMENT MEETINGS V.1 Exit Meeting Summary An exit meeting was conducted on March 7, 2013, to present inspection results to you 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.
