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 six-week period of inspections in the areas of quality assurance, identification and resolution of construction problems, construction activities, fire protection, and follow-up of other activities. The inspection program for Unit construction activities is described in NRC Inspection Manual Chapter 2517. Information regarding the WBN Unit Construction Project and NRC inspections can be found at http://www.nrc.gov/reactors/plant-specific-items/watts-bar.html.

Inspection Results

A Severity Level (SL) IV non-cited violation (NCV) of Code of Federal Regulations (CFR) Part 50, Appendix B, Criterion XVI, "Corrective Action" was identified for inadequate measures to assure that conditions adverse to quality were identified and corrected. Specifically, a nonconformance identified by quality control (QC) and associated with anchor bolt spacing on a pipe support was not corrected. (Section C.1.7)

A SL IV NCV of CFR Part 50, Appendix B, Criterion III, "Design Control," was identified for the failure to include all material requirements for swing check valves into design specifications. Specifically, the design specifications failed to include the material requirements for internal bolting, shafts, and pins for swing check valves. (Section OA.1.6)

The inspectors concluded that concerns pertaining to several Three Mile Island (TMI) action items, Bulletins (BL), Generic Letters (GL), and construction deficiency reports have been appropriately addressed for WBN Unit 2. These items are closed.

Quality assurance requirements for preoperational testing were established and were being met for this stage of the preoperational test program. TVA has established adequate programmatic controls for preoperational testing. These controls were in accordance with applicable commitments and regulatory requirements.

Other areas inspected were adequate with no findings of significance identified. These areas included various Unit Corrective Action Programs (CAPs)/Special Programs (SPs); electrical systems and components; mechanical systems and components; nuclear welding; structural concrete; nondestructive examination (NDE), and in-service inspection activities; refurbishment; environmental activities; and fire protection.

b. Observations and Findings

The inspectors identified the following non-cited violation (NCV):

Introduction:

On April 26, 2011, the inspectors identified a violation of 10 CFR 50, Appendix B, Criterion XVI, "Corrective Action," for inadequate measures to assure that conditions adverse to quality were identified and corrected. Specifically, a nonconformance identified by QC and associated with anchor bolt spacing on a pipe support was not corrected.

Description:

On April 20, 2011, the inspectors performed a walkdown of newly installed pipe supports to determine whether the as-installed configurations matched those specified by the applicable DRAs. The inspectors identified an example where the configuration did not meet the minimum spacing requirements for a wedge bolt anchor installed in the baseplate of support 2-47A465 014 for the safety-related reactor coolant system (RCS). Specifically, the inspectors identified that pipe support 2-47A465 014, as shown in DRA 53123-055, required a 51/2-inch spacing between a 3/4-inch wedge bolt and a 1/4-inch expansion shell anchor (SSD/SDI anchors), and the as-built configuration measured had a 4-inch spacing. This did not meet the minimum spacing requirements, specified in Modification and Addition Instruction (MAI)-5.1B, "Wedge Bolt Anchor Installation," Rev 19. During the inspection, the applicant informed the inspectors that the spacing discrepancy had been previously addressed in the corrective action program and documented in PER 229082.

On April 26, 2011, the inspectors reviewed PER 229082, "Anchor Bolt Spacing Violation," and discovered that the PER and associated actions were closed and archived on September 8, 2010. PER 229082 was initiated on May 8, 2010, to document discrepancies identified between MAI-5.1B, Table 6.2.3D and the installed conditions of support 2-47A465 014 as noted in WO 09-952202-011, engineering document construction release (EDCR) 53123, and DRA 53123-055. During that time, QC rejected the installed configuration for the support due to a 4-inch spacing between a 3/4-inch wedge bolt and a 1/4-inch SSD/SDI anchor, when 51/2-inch spacing was required per MAI-5.1B Table 6.2.3D. The corrective action plan specified in PER 229082 was misleading and included rework of support 2-47A465 014 to obtain the proper gap; however, the anchor bolt spacing was never addressed or corrected. On May 2, 2011, the applicant issued PER 364388 to document the inappropriate closure of PER 229082.

This finding was determined to be more than minor because it represented an improper or uncontrolled work practice that could impact the quality or safety of a safety-related pipe support, in that the failure to appropriately disposition the non-conforming condition led to the inadvertent use of anchor bolts that did not meet the required spacing requirements. The finding was of very low safety significance because the engineering evaluation and reanalysis of the as-built pipe support determined it to be acceptable. No cross-cutting aspect was identified.

Enforcement:

10 CFR 50, Appendix B, Criterion XVI, "Corrective Action," requires, in part, that measures shall be established to assure that conditions adverse to quality, such as deficiencies, deviations, defective materials, and nonconformances are promptly identified and corrected.

Contrary to the above, corrective actions documented in PER 229082 failed to assure that a nonconformance identified by QC, specifically an anchor bolt spacing violation, was corrected.

The PER was closed inappropriately after inadequate corrective actions had been completed without correcting the as-built nonconforming configuration. This finding was determined to be a SL IV violation using Section 6.5 of the Enforcement Policy. Because this SL IV violation was entered into the corrective action program as PER 364388, this violation is being treated as an NCV consistent with Section 2.3.2 of the NRC Enforcement Policy: NCV 05000391/2011604-01: Failure to Correct a Nonconformance.

c. Conclusions

The inspected activities associated with NCV 05000391/2011604-01 discussed above were not performed in accordance with applicant procedures and NRC regulations; however, other activities observed were performed in accordance with applicable procedures. C.1.8 Containment Penetrations (Mechanical) - Work Observation (IP 53053)

a. Inspection Scope

Background: The purpose of this IP was to confirm adequate installation of mechanical penetrations. This IP covers material certification, method of assembly, protection, installation activities, nondestructive examination, and inspection as well as a semi-annual requirement to observe installation and confirm adequacy of documents used for installation. A reconstitution of historic Unit 2 inspection results identified that inspection requirements were not met and that only minimal samples were noted. Because of this, it was recommended that inspection efforts look at a minimum of three penetrations, if possible. A majority of the mechanical containment penetrations were previously installed prior to initial suspension of the Unit 2 construction effort.

Inspection Activities: The inspectors observed construction activities associated with the installation of anchor sleeves for mechanical containment penetrations of the safety injection (SI) system.

The inspectors reviewed the work instructions, design drawings, and material traceability and transfer records to ensure that the work was planned to occur with the proper materials on the proper component. The inspectors also reviewed work instructions, nondestructive examination (NDE) acceptance documents, and personnel qualification records to ensure that the work was performed in accordance with accepted procedures, by qualified personnel, and ultimately accepted by the QC organization. Additional documents reviewed are included in the attachment.

The following work was inspected:

Penetration X-20A , SI System Pump Discharge, Anchor Sleeve

Penetration X-20B , SI System Pump Discharge, Anchor Sleeve The following sample was inspected:

IP 53053 Section 02.01 - 2 samples

b. Observations and Findings

No findings of significance were identified.

c. Conclusions

Work associated with containment mechanical penetrations X-20A and X-20B was performed per the associated WO and test package instructions.

C.1.9 Nuclear Welding General Inspection Procedure (IP 55050)

a. Inspection Scope

Background: The welding CAP was initiated in the mid-1980s to address several welding related issues. Sub-Issue 2, "Radiographs for ASME Piping Welds," was initiated when radiographs showing rejectable indications were found to have been accepted by the film interpreter. The corrective actions on Unit 1 consisted of a complete review of all radiographs (representing over 2700 welds), 350 of which were subsequently rejected and repaired.

For Unit 2 a complete review of all historical radiographs and records was performed resulting in 282 welds and their radiographs being rejected for indications or unacceptable film quality. Approximately 80 of the 282 welds were found rejectable and required repair or cut-out. These Unit 2 actions are controlled under PER 170933.

Inspection Activities: NRC's Integrated Inspection Report (IIR) 0500391/2010603, Section C.1.15, documents the programmatic inspection of Bechtel's welding program. The inspectors reviewed field weld records and observed piping internal welds to verify Bechtel's control of production welding activities on the SI piping system. The inspectors reviewed the historical radiographs that were rejected due to an unacceptable flaw size for one of the historical welds joining the elbow fitting and pipes. The original welds to the existing elbow fitting were both cut-out. The welding inspection was performed for the new replacement elbow fitting and adjoining pipe sections. This safety-related welding was inspected to verify compliance with the requirements of the ASME Section III, Subsection NC code for Class 2 (TVA Class B) components.

The inspectors reviewed Bechtel records and observed the two completed stainless steel welds to the new elbow fitting, identified as field weld numbers (FW-No.) 23 and 26, documented as 2-063A-D124-23 Cut out # and Repair # (C0R0) and 2-063A-D124-26 C0R0. These two welds join a new replacement 8-inch diameter long radius 90 degree elbow fitting with two pipe sections. The internal root pass of completed welds was accepted by Bechtel's QC for both open-butt joints and was accessible for inspection by the NRC. The inspectors reviewed Bechtel's weld map FSK-M-3009 to verify that weld records correspond with assigned field weld numbers.

The inspectors reviewed Bechtel's field welding checklists (Form WR-5) for FW-No. 23 and 26 to verify these records met the requirements of Bechtel's WD-1 welding standard for documentation of welds. The inspectors also reviewed the contents of form WR-5 to determine if the recorded welding procedure, pipefitter-welder qualifications, and certified material test report (CMTR) with traceable heat numbers for the new elbow fitting, adjoining pipe sections, weld filler metals, and QC hold points met the requirements of Bechtel's Special Process Manual (SPM) and General Welding Standard, (GWS) 1 and ASME code of record. Documents reviewed are listed in the attachment.

b. Observations and Findings

No findings of significance were identified.

c. Conclusions

The observation and review of associated records for two pipe field welds that join a new replacement fitting with two pipe sections met the requirements of 10 CFR Part 50, Appendix B; Bechtel's Quality Assurance and SPM; and the applicant's quality assurance manual for the code of record.

C.1.10 Reactor Vessels Internals (Welding) Observation of Welding and Associated Activities (IP 55093)

a. Inspection Scope

The inspectors reviewed field weld records and observed reactor pressure vessel (RPV) internal welds to verify Bechtel's control of production welding activities beneath the upper head of the reactor vessel. The inspection was performed for fillet welds joining the 3-inch diameter portion of the conical shape funnel guides and the thermal sleeve tubes. This safety-related nonpressure boundary welding was inspected to verify compliance to the requirements of the ANSI B31.1 code of record.

The inspectors reviewed Bechtel records and observed six completed stainless steel weld locations identified and documented as FW-Nos. 7, 11, 14, 32, 37, and 48. These typical fillet welds consisted of 1/8-inch leg size with lengths ranging between 2 and 21/2-inches for two locations spaced 150° to 180° apart. The smooth weld area surfaces were free of deleterious materials and aligned as indicated on the Bechtel's DRA 54835-003.

The inspectors reviewed Bechtel's weld map WM-M-007 to verify that weld records corresponded with 6 of the 57 assigned field weld identification numbers.

The inspectors reviewed Bechtel's miscellaneous and structural field welding checklists (Form WR-5C) for FW-Nos. 1 through 48 to verify these records met the requirements of Bechtel's WD-1 welding standard for documentation of welds. The inspectors reviewed the contents of the WR-5C for the above six field welds to determine whether the recorded welding procedure, weld joint alignment, welder qualifications, control of weld filler metals, QC hold points, and final weld dimensions and surface appearance met the requirements of Bechtel's SPM and GWS-1 general welding standard, and the ANSI code of record.

Visual examination (VT) of the completed fillet welds was performed in accordance with Bechtel's Nondestructive Examination Standard Visual Examination, VT - ANSI B31.1 1973. This Bechtel NDE-VT standard for visual examination of welds was reviewed for compliance to the applicable requirements of ANSI B31.1, Chapters V and VI. Documents reviewed are listed in the attachment. The inspectors performed the following samples:

IP 55093 02.01 - six samples

IP 55093 02.02 - six samples

IP 55093 02.03 - two samples

IP 55093 02.04 - six samples

b. Observations and Findings

No findings of significance were identified.

c. Conclusions

The observation of six field welds and review of associated weld records of 48 field welds met the requirements of 10 CFR Part 50, Appendix B; Bechtel's quality assurance and special processes manuals; and TVA's quality assurance manual for the code of record. C.1.11 Nuclear Welding General Inspection Procedure (IP 55050)

a. Inspection Scope

The inspectors reviewed Westinghouse Electric Corporation (WEC) Drawing No. 1546E86 for the steam generator upper internal drain lines to verify the adequacy of welding symbols associated with these lines. A September 15, 1986, revision to the drawing changed the welding symbols from full penetrations welds to partial penetration welds for 6-inch and 4-inch diameter schedule 40 pipes.

Documents reviewed are listed in the attachment.

b. Observations and Findings

No findings of significance were identified.

c. Conclusions

The revision to the drawing met the requirements of 10 CFR Part 50, Appendix B, and TVA's quality assurance manual.

IV.

OTHER ACTIVITIES

OA.1.1 (Discussed) Instrument Line CAP (TI 2512/026, IPs 49063 and 49065)

a. Inspection Scope

The inspectors reviewed the applicant's implementation plan for the Unit 2 instrument line CAP and discussed the plan with the CAP owner to determine if the plan for Unit 2 was consistent with the Unit 1 approach. The inspectors reviewed procedures for installing instrument lines to determine if appropriate recurrence controls remained in place. The inspectors reviewed the applicant's actions to verify the proper slope of instrument lines. The inspectors reviewed drawings and specifications to identify the scope of instrument lines with associated slope requirements. From that review, the inspectors selected 150 instruments to determine if their associated lines were included in the applicant's scope for slope verification and whether the slope verification criteria provided in the associated EDCRs was consistent with engineering specifications.

The inspectors walked down accessible portions of 16 safety-related instrument lines from the process pipe connection to the instrument panel in the essential raw cooling water (ERCW) system that were installed under EDCR 53630 and WO 110692086 to determine if the completed installation conformed to:

Applicable construction/installation specifications;

QC inspection requirements;

Work performance procedures; and,

Applicable field drawings contained in the WO Specifically, the inspectors measured the instrument lines to determine if they were properly sloped and supported, the correct pipe size, and if the actual field configuration matched the isometric drawings. The inspectors reviewed the completed WO to determine if welding was performed in accordance with ASME Section III requirements. The inspectors reviewed 13 related audits to determine if:

The audits were reported in sufficient detail to permit a meaningful assessment by those responsible for corrective action, final disposition, and trending;

The applicant had taken proper follow-up action on identified deficiencies; and,

Any trends existed which could indicate inadequate corrective actions.

Specific documents reviewed are listed in the attachment. The following samples were inspected:

IP 49063 Section 02.02 - one sample

IP 49063 Section 02.03 - one sample

IP 49065 Section 02.03 - one sample

b. Observations and Findings

No findings of significance were identified.

c. Conclusions

The instrument sensing line CAP activities observed were adequate and completed in accordance with applicable drawings and specifications. The inspectors did not identify any discrepancies between actions planned for Unit 2 and actions committed to in the September 26, 2008 regulatory framework letter. Based on this limited review and the outstanding actions by the applicant, no additional conclusion is warranted for this inspection. OA.1.2 (Discussed) Environmental Qualification (EQ) SP (TI 2512/036)

a. Inspection Scope

The inspectors reviewed the applicant's program of 10 CFR 50.49, "Environmental qualification of electric equipment important to safety for nuclear power plants," by examining various EQ documents, drawings, and procedures associated with WBN Unit 2. Additionally, the inspectors reviewed several open items associated with the EQ program that were identified in Supplemental Safety Evaluation Report (SSER) 22 for WBN Unit 2, specifically open items 18, 19, 20, 23, and 24 of Appendix HH of SSER 22. The inspectors reviewed 25402-3DP-GEE-00001, "WBN Unit 2 Equipment Environmental Qualification Program," Rev. 1, to verify the definition of a harsh environment was in compliance with 10 CFR 50.49. The inspectors selected a sample of ERCW system EQ components from calculation EDQ002999-20090011, "Appendix A - WBN Unit 2, List of 10CFR50.49 Components by System." Specifically, the inspectors selected Motor Operated Valves (MOVs), 2-MVOP 0091B, 0096B, 0099A, and 0104A from the list and visually inspected the MOVs to verify the components were located in the area identified in the calculation. The inspectors reviewed the associated environmental data drawings 2-47E235-41 and 42 to verify the harsh environmental data was identified. The inspectors reviewed procurement packages for cables (PO103131-MRA-EWG2-00002, EWE 00034, WB2 0230) and Namco limit switches (PO 26088) to verify that the EQ requirements were included.

The inspectors reviewed the following sections of the EQ binder for Namco EC290 series connectors, WBNEQ-CSC-005, to verify qualification was adequately documented including periodic maintenance requirements to maintain qualification and a positive statement that the documentation had been reviewed and approved and that the equipment was determined to be qualified for its application:

Tab B, Checklist for Environmental Qualification

Tab C, Analyses and Justification Documents reviewed are listed in the attachment.

b. Observations and Findings

No findings of significance were identified.

c. Conclusions

The inspectors determined that the samples associated with the EQ SP were in compliance with requirements. EQ activities are still in process and will require further inspection. OA.1.3 (Discussed) SSER 22 Appendix HH: Open Item 20

a. Inspection Scope

The inspectors reviewed Open Item 20 in SSER 22, Appendix HH for WBN Unit 2 which is identified as follows: Resolve whether or not routine maintenance activities should result in increasing the EQ of the 6.9 kilovolt motors to Category I status in accordance with 10 CFR 50.49.

The inspectors interviewed the EQ program owners to determine the basis of maintaining the 6.9 kV motors as EQ Category II as opposed to upgrading the motors to EQ Category I requirements in accordance with 10 CFR 50.49(l). The inspectors reviewed calculation SS-E18.10.01, "Environmental Qualification Requirements for Safety Related Electrical Equipment" to evaluate the applicant's EQ assessment of the motors.

b. Observations and Findings

The inspectors determined that the impact of the layup period on the 6.9 kV Westinghouse motors was adequately addressed. The inspectors were unable to confirm the applicant was properly addressing the 10 CFR 50.49(l) upgrade requirements as a result of refurbishment/maintenance activities performed on these motors.

c. Conclusions

Further inspection will be required to verify the applicant is addressing the 10 CFR 50.49(l) upgrade requirements as a result of refurbishment/maintenance activities performed on the 6.9 kV motors. Therefore, SSER22 Appendix HH open item 20 remains open. OA.1.4 (Discussed) SSER 22 Appendix HH: Open Item 23

a. Inspection Scope

The inspectors reviewed Open Item 23 in SSER 22, Appendix HH for WBN Unit 2 which is identified as follows: Resolve whether or not TVA's reasoning for not upgrading the main steam isolation valve solenoid valves to Category I is a sound reason to the contrary, as specified in 10 CFR 50.49(l). 10 CFR 50.49(l) requires replacement EQ components to be qualified to Category I requirements unless there are sound reasons to the contrary. The inspectors conducted interviews with the EQ program owners to evaluate the applicant's basis for not upgrading the main steam isolation valve solenoid valve to Category I requirements.

b. Observations and Findings

An interview with the EQ program owners identified that the applicant has submitted a service requisition for EQ testing to qualify the main steam isolation valve solenoid valve to EQ Category I requirements. The persons interviewed stated that all other EQ components being replaced or refurbished at WBN Unit 2 are being upgraded to the Category I requirements. The inspectors reviewed the service requisition 25402 SRA-NEE0-00002 and confirmed that the EQ requirements were identified.

c. Conclusions

Further inspection will be required to verify the adequacy and results of the environmental qualification test report for the main steam isolation valve solenoid valves. Therefore, SSER22 Appendix HH open item 23 remains open.

OA.1.5 (Discussed) SSER 22 Appendix HH: Open Item 24

a. Inspection Scope

The inspectors reviewed Open Item 24 in SSER 22, Appendix HH for WBN Unit 2 which is identified as follows:

The NRC staff requires supporting documentation from TVA to justify its establishment of a mild environment threshold for total integrated dose of less than 1x103 rads for electronic components such as semiconductors or electronic components containing organic material.

The inspectors reviewed calculation 72186 RDM, "A Review of Electronic Components in a Radiation Environment of 5x104 rads", to determine the adequacy of the radiation threshold for electronic components such as semiconductors or electronic components containing organic material.

b. Observations and Findings

No findings of significance were identified.

c. Conclusions

Further inspection will be required to verify the adequacy of the applicant's radiation threshold for electronic components that are more sensitive to the effects of radiation. Therefore, SSER22 Appendix HH Open Item 24 remains open. OA.1.6 (Discussed) NRC BL 89-02: Stress Corrosion Cracking of High-Hardness Type 410 Stainless Steel Internal Preloaded Bolting in Anchor Darling Model S350W Swing Check Valves or Valves of Similar Design (IP 50073)

a. Inspection Scope

The inspectors observed maintenance and reviewed documents related to the applicant's implementation of BL 89-02 at Watts Bar Unit 2. The inspectors observed work on one check valve, 2-CKV 0580C, under WO 08-953588-000 to determine if:

Appropriate drawings and work procedures were available to the installers;

Installation requirements, construction drawings, specifications, and work procedures were technically adequate and of the latest approved issue;

Appropriate replacement parts were specified;

The applicant properly pre-planned the work; and,

The applicant performed the work in accordance with the work instructions. During an in-office review, the inspectors reviewed the applicant's final closure report for the BL to determine if the licensee adequately addressed all of the issues discussed in the BL. To determine this, the inspectors:

Reviewed the applicant's efforts to identify all applicable safety-related check valves with either internal pins, shafts, or bolting made of materials susceptible to stress corrosion cracking;

Reviewed corrective actions taken or planned to determine if they were consistent with the actions taken for Unit 1;

Reviewed documentation to determine if recurrence controls remained in place; and,

Reviewed issues entered into the corrective action program to determine if appropriate corrective actions were either taken or planned.

During the in-office review, the inspectors randomly sampled four safety-related check valves and reviewed procurement documents and vendor drawings for each valve. The inspectors identified the materials of construction of the internal pins, shafts, and bolting for each valve to determine if any materials susceptible to stress corrosion cracking were used and to evaluate the adequacy of the applicant's scope of review. Documents reviewed are listed in the attachment. The following sample was inspected:

IP 50073 Section 02.02c - one (safety-related check valve outside the reactor coolant pressure boundary

b. Observations and Findings

Introduction:

The inspectors identified a SL IV NCV of 10CFR50, Appendix B, Criterion III, "Design Control," for the failure to include all material requirements for swing check valves into design specifications.

Description:

During their BL 89-02 review for Unit 1, the applicant determined that the material requirements for internal bolting also applied to internal shafts and pins and that one of the prohibited materials for these parts was high-hardness American Society of Testing and Materials (ASTM) A276-410T. The applicant intended to use various specifications to provide material requirements for Unit 2 swing check valves but failed to incorporate the material requirements for internal bolting, shafts, and pins into all of the specifications. One of the specifications that failed to include these requirements was WBNP-DS-501433-0904.

As part of the refurbishment program, the applicant procured new swing check valves for 2-CKV 0679, Component Cooling System Thermal Barrier Supply Check Valve, and 2-CKV 0873, Auxiliary Feedwater Loop 1 Check Valve. The applicant used WBNP-DS-501433-0904 to provide the procurement material requirements for both valves. Because the specification did not provide the hinge pin material requirements, the manufacturers used their standard material, high-hardness ASTM A276-410T for both valves. The applicant discovered the improper hinge pin material for 2-CKV 0679 on or about December 21, 2010, and later installed an appropriate hinge pin but failed to enter the issue into their corrective action program. This failure contributed to the applicant improperly approving submittal drawing 09-56866-02 for 2-CKV 0873 on February 15, 2011, which identified the hinge pin material as "A276-410T." During subsequent BL 89-02 reviews, the applicant identified the improper hinge pin material for this valve on or about April 5, 2011. The applicant contacted the manufacturer to modify the hinge pin material.

On April 13, 2011, the applicant discussed the final results of their BL 89-02 review with the inspectors. The inspectors learned that the applicant did not enter either hinge pin deficiency into their corrective action program and were not planning to do so at the time. The inspectors questioned if the design specifications properly specified the material requirements for their swing check valves. As a result of the inspectors' questions, the applicant determined that at least three design specifications, including WBNP-DS-501433-0904, failed to provide all material requirements for swing check valves. The applicant entered these issues into their corrective action program as PER 356559 to review and correct the cause of the deficient design specifications, the extent of condition, and the failure to initiate a timely PER to document conditions adverse to quality. This issue was NRC-identified because the applicant failed to identify the inadequate design specifications and failed to enter the issues into their corrective action program until after questioned by the inspectors. The finding was more than minor because it represented an inadequate process that, if left uncorrected, could adversely affect the quality of the fabrication, construction, testing, analysis, or records of a safety-related structures, systems, and components. Specifically, design specifications failed to include all material requirements for swing check valves. The finding is of very low safety significance because the incorrect material was not included in permanently installed safety-related equipment.

The apparent cause of this finding has a cross-cutting aspect related to ineffective implementation of a corrective action program with a low threshold for identifying issues. (P.1(a)). Specifically, the failure to enter the hinge pin deficiency into the corrective action program in December 2010 contributed to the failure to take comprehensive corrective actions that could have prevented the improper vendor submittal drawing approval in February 2011.

Enforcement:

Appendix B, Criterion III, "Design Control" of 10 CFR Part 50, states, in part, that: "Measures shall be established to assure that applicable regulatory requirements and the design basis- are correctly translated into specifications, drawings, procedures, and instructions." Contrary to the above, prior to April 5, 2011, the applicant failed to correctly translate all design basis requirements into specification WBNP-DS-501433-0904. Because this was a SL IV violation and the violation and was entered into the applicant's corrective action program, this violation is being treated as an NCV, consistent with Section 2.3.2 of the NRC Enforcement Policy,05000391/2011604-02, "Failure to Maintain Adequate Design Specifications."

c. Conclusions

With the exception of NCV 05000391/2011604-02, applicant actions taken or planned were adequate to ensure the commitments made for BL 89-02 have been met and conformed to applicable regulatory requirements. BL 89-02 remains open pending review of all completed actions related to the bulletin.

OA.1.7 (Closed) NRC Bulletin (BL) 80-18: Maintenance of Adequate Minimum Flow thru Centrifugal Charging Pumps (CCPs) Following Secondary Side High Energy Line Rupture (IP 92717)

a. Inspection Scope

Background: BL 80-18 notified licensees that, under certain conditions, the CCPs could be damaged due to a lack of minimum flow before SI termination criteria were met. The particular circumstances that could result in damage involved unavailability of the pressurizer power operated relief valves (PORVs), with operation of one or more CCPs repressurizing the reactor during a safety injection, following a secondary system high energy line break. Since the SI signal automatically isolates the CCP mini-flow return line, the flow through the CCPs is determined by the individual pump characteristic head vs. flow curve, the pressurizer safety valve setpoint, and the flow resistances and pressure losses in the piping and in the reactor core. That minimum flow might not be adequate to ensure pump cooling, and resulting pump damage could violate design criteria before current SI termination criteria were met. The applicant accomplished the necessary actions for BL 80-18 for Unit 1 and the results were verified in IR 50-390/82-41, dated January 12, 1982, and IR 50-390/85-60, dated December 6, 1985.

Inspection Activities: The inspectors reviewed historical documentation to verify that the proposed actions for Unit 2 were consistent with those completed on Unit 1. Specifically, the inspectors reviewed commitment closure document NCO080008044 which outlined the method for Unit 2 completion of BL 80-18 actions. These actions consist of implementation of EDCR 52328, to remove the automatic closure signals to valves in the CCP mini-flow recirculation line, and procedural changes to emergency operating instructions and system operator instructions, that will maintain the valves in the proper position to protect the CCPs from the scenario identified in BL 80-18. Specific documents reviewed are listed in the attachment to this report.

b. Observations and Findings

No findings of significance were identified.

c. Conclusions

The inspectors determined that the proposed actions are consistent with those implemented for Unit 1 and would satisfy the applicable requirements in BL 80-18.

Therefore, inspection efforts associated with BL 80-18 are complete and closed. OA.1.8 (Closed) NRC BL 80-20: Failure of Westinghouse Type W-2 Spring Return to Normal Control Switches (IP 92717)

a. Inspection Scope

Background: BL 80-20 notified licensees that, even though the subject switches were in the proper position, loss of continuity through the neutral position contact could remain undetected until the equipment associated with the switch were called upon to operate. This condition would be equivalent to bypassing the system associated with the switch. Recommendations were to re-wire the switch to alleviate this issue. Expected actions were to identify where these switches were installed in safety-related applications and re-wire or replace the switches. In a letter to the NRC dated June 2, 1982, TVA identified 67, Unit 1 and Unit 2, safety-related switches in need of modification and subsequently addressed them in Calculation E27885081201 and associated design packages. Additionally, in a letter to the NRC dated August 31, 1989, TVA identified an additional six switches ( four for Unit 1 and two for Unit 2) affected by BL 80-20 and committed to correct these prior to fuel load of the respective unit. Calculation E27885081201 was revised and the additional six switches were appropriately modified. The results of TVA's actions for BL 80-20 were verified in IR 50-390,391/94-35. Inspection Activities: The inspectors reviewed historical documentation to verify that the required actions were completed. Specifically, the inspectors reviewed commitment closure document NCO850423004 which outlined the method for completion of BL 80-20 actions. As mentioned above, Calculation E27885081201 was the governing document for the classification and correction of applicable switches. The inspectors reviewed the calculation to verify that switches were appropriately screened for safety significance and also reviewed the justification for either repair or replacement. Additionally, the inspectors sampled various affected switches by reviewing the schematic diagrams and switch contact developments to ensure that the repairs were appropriately performed and documented. Additional field inspection of main control room equipment installation was performed as documented in NRC IIR 05000391/2010605 (Section OA.1.4). Specific documents reviewed are listed in the attachment to this report.

b. Observations and Findings

No findings of significance were identified.

c. Conclusions

The inspectors determined that the actions were consistent with those implemented for Unit 1 and satisfy the applicable requirements in BL 80-20. Therefore, inspection efforts associated with BL 80-20 are complete and closed. OA.1.9 (Closed) NRC Generic Letter (GL) 93-04: Rod Control System Failure and Withdrawal of Rod Control Cluster Assemblies (IP 92717)

a. Inspection Scope

Background: GL 93-04 notified licensees about a single failure vulnerability within the Westinghouse solid state rod control system that could cause an inadvertent withdrawal of control rods in a sequence resulting in a power distribution not considered in the design basis analyses. The Westinghouse owners group (WOG) met and published documents validating the NRC concern and proposing methodologies to correct the issue. NRC letter to TVA dated December 9, 1994, identified that the NRC approved of the WOG approach to resolve the concern and reiterated TVA's commitment to resolve the issue for Watts Bar Unit 1 prior to initial criticality. Watts Bar Unit 1 subsequently modified the rod control system logic (design change notice [DCN] W-34191-A) by making current order timing adjustments to prevent any uncontrolled asymmetric rod withdrawal in the event of a system failure. SER Supplement 16, dated September 1995, indicated that the NRC staff was satisfied with TVA's commitments to resolve the concerns surrounding GL 93-04 and closed the issue for Unit 1.

Inspection Activities: The inspectors reviewed historical documentation to verify that the required actions for Unit 1 were completed. Additionally, the inspectors reviewed commitment closure document NCO930239004, which outlined the method for completion of GL 93-04 actions on Unit 2. This methodology consisted of contracting Westinghouse, the designer of both Unit 1 and Unit 2 systems, to refurbish the Unit 2 rod control system to be functionally the same as that in use on Unit 1. The inspectors reviewed the contract order to Westinghouse, communications between Westinghouse and TVA regarding system board upgrades and compatibility, EDCR 52324, and applicable WOs to verify that the Unit 2 rod control system will be functionally identical to that of Unit 1 and satisfy the requirements of GL 93-04. Specific documents reviewed are listed in the attachment to this report.

b. Observations and Findings

No findings of significance were identified.

c. Conclusions

The inspectors determined that the proposed actions are consistent with those implemented for Unit 1 and would satisfy the applicable requirements in GL 93-04. Therefore, inspection efforts associated with GL 93-04 are complete and closed. OA.1.10 (Closed) Inspection of 10 CFR Part 21 and 10 CFR50.55(e) Programs for Reporting Defects and Noncompliance (IP 36100)

a. Inspection Scope

The purpose of this IP was to verify that Watts Bar Unit 2 had established a program and procedures to effectively implement 10 CFR Part 21 and 10 CFR5 0.55(e) requirements for reporting defects and failures associated with a substantial safety hazard. Reconstitution of this IP was determined to be unnecessary because the programs, instructions, and procedures were common during initial construction of both units, and the Unit 1 reconstitution effort documented in NUREG-1528, "Reconstitution of the Manual Chapter 2512 Construction Inspection Program for Watts Bar Unit 1," Appendix C, "Organization and Administration," confirmed adequate reviews were completed. However, a sample of new procedures, in the area of reporting requirements, covered by this IP, were inspected and the results are documented in this report. This program was initially inspected at the beginning of resuming the WBN2 construction project and is documented in IIR 05000391/2008009, Section E.1.3.

The inspectors reviewed the applicant's process for identifying and evaluating deviations and failures. This consisted of reviewing corrective action program procedures to ensure that measures existed for review and timely processing of potential deviations. The inspectors reviewed QA audit results focused on defect identification and evaluation and also reviewed a sample of completed deviation evaluations, that did not result in the identification of a defect or failure to comply, to ensure that items were properly documented, screened, and evaluated. The inspectors reviewed WBN2 procedure NGDC PP-13, "NRC Reporting Requirements", to ensure that the applicant's program identified the proper time frames for directors or responsible officers to notify the NRC of identified defects. The procedure was also reviewed to verify that guidance was provided on what information was necessary when providing a submittal to the NRC. While no notifications of defect have occurred, the inspectors reviewed the available documentation to ensure that the procedure provided guidance regarding a potential significant breakdown of the 10 CFR Part 50 Appendix B QA program.

The inspectors reviewed a number of procurement documents to ensure that each applicable procurement document specified the proper applicability to 10 CFR Part 21 and identified the length of time the records were to be maintained. These aspects are also routinely reviewed by inspectors when implementing the receipt, storage, and installations sections of applicable IPs.

The inspectors reviewed documentation to ensure that proper posting requirements were prescribed and witnessed the presence of current postings at conspicuous locations to ensure that they contained the information required by 10 CFR 21.6 and 10 CFR 50.55(e)(2).

The following samples were inspected during this inspection period:

IP 36100 Section 02.01 - one sample

IP 36100 Section 02.02 - one sample

IP 36100 Section 02.03 - one sample

IP 36100 Section 02.04 - one sample

IP 36100 Section 02.05 - one sample Specific documents reviewed are listed in the attachment.

b. Observations and Findings

No findings of significance were identified. A number of qualified programs and procedures are implemented to satisfy the requirements of IP 36100. Many of these programs receive routine inspection and have not been identified as being deficient in procedure or process.

c. Conclusions

The procedures and records reviewed during this inspection period, associated with defect and noncompliance reportability, were found to conform to the applicable regulatory requirements. This IP is considered closed; however, if major changes to the applicant's instructions and procedures are identified through observation of future work activities, the inspectors will inspect those as necessary to satisfy the requirements in this procedure.

OA.1.11 (Closed) TMI Action Item II.F.1.2.d, Verify Installation of Containment Pressure Monitors (IP 92717)

a. Inspection Scope

Background: As a result of the accident at TMI-2, the NRC created a number of action items designed to improve a plant's ability to minimize accident occurrence and accident consequences. These TMI action items were initially outlined in NUREG-0660, "NRC Action Plan Developed as a Result of the TMI-2 Accident" and later clarified in NUREG-0737, "Clarification of TMI Action Plan Requirements." TMI Action Item II.F.1.2.d was created to ensure that a mechanism existed to measure and continuously monitor primary containment pressure from the MCR. Regulatory Guide 1.97, "Criteria for Accident Monitoring Instrumentation for Nuclear Power Plants" was referenced as the guide for the design and qualification of the containment pressure monitor. Subsequently, Watts Bar Unit 1 installed the required equipment, and it was discussed in NUREG-0847, "Safety Evaluation Report related to the operation of Watts Bar Nuclear Plant, Units 1 and 2," Supplement 5. This Safety Evaluation Report identified, in part, that "The staff has verified that the applicant has installed these monitors (see Inspection Report 50-390/84-59, dated November 7, 1984)." Inspection Activities: Based on the information provided in the background section, the objective of this inspection was to gather and evaluate sufficient information to make a determination as to whether TVA had adequately addressed TMI Action Item II.F.1.2.d for WBN2. The inspection focused on a review of various documents describing the methodology the applicant has initiated to satisfy the TMI action item. Differences between the Unit 1 completion and Unit 2 resolution were identified by the applicant and reviewed by the inspectors. Primarily, these differences are a result of the applicant taking advantage of improved equipment through obsolescence of original equipment.

The projected equipment meets NRC regulatory requirements and satisfies the intent of the TMI action item regarding containment pressure monitoring. The justification for the change from Unit 1 equipment, applicable regulatory requirements, work instructions, purchase memorandum forms, and procurement specifications were all reviewed to verify that the intent of the TMI action item was satisfied. Additional field inspection of MCR equipment installation was performed as documented in NRC IIR 05000391/2010605, Section OA.1.4. Specific documents reviewed are listed in the Attachment to this report.

b. Observations and Findings

No findings of significance were identified.

c. Conclusions

The inspectors reviewed various completed actions associated with TMI Action Item II.F.1.2.d to verify the adequacy of the applicant's actions. The inspectors concluded that the applicant's efforts were sufficient to satisfy the intent of the respective TMI action item. TMI Action Item II.F.1.2.d is considered closed. OA.1.12 (Closed) TMI Action Item II.F.1.2.f, Verify Installation of Containment Hydrogen Accident Monitoring Equipment (IP 92717)

a. Inspection Scope

Background: As a result of the accident at TMI-2, the NRC created a number of action items designed to improve a plant's ability to minimize accident occurrence and accident consequences. These TMI action items were initially outlined in NUREG-0660, "NRC Action Plan Developed as a Result of the TMI-2 Accident" and later clarified in NUREG-0737, "Clarification of TMI Action Plan Requirements." TMI Action Items II.F.1.2.f was created to ensure that a mechanism existed to measure and continuously monitor primary containment hydrogen concentration from the MCR. Regulatory Guide 1.97, "Criteria for Accident Monitoring Instrumentation for Nuclear Power Plants" was referenced as the guide for the design and qualification of the containment hydrogen monitor. Subsequently, Watts Bar Unit 1 installed the required equipment and it was discussed in NUREG-0847, "Safety Evaluation Report related to the operation of Watts Bar Nuclear Plant, Units 1 and 2," Supplement 5. This Safety Evaluation Report identified that "The staff has verified that the applicant has installed these monitors (see Inspection Report 50-390/84-85, dated January 8, 1985)."

Additionally, IR 50-390/95-74 "verified that the hydrogen monitoring system had been tested under the preoperational test program and that there were no deficiencies or open conditions associated with the hydrogen monitoring system." Inspection Activities: Based on the information provided in the background section, the objective of this inspection was to gather and evaluate sufficient information to make a determination as to whether TVA had adequately addressed TMI Action Item II.F.1.2.f for WBN2. The inspection focused on a review of various documents describing the methodology the applicant has initiated to satisfy the TMI ation item. Differences between the Unit 1 completion and Unit 2 resolution were identified by the applicant and reviewed by the inspectors. Primarily, these differences are a result of the applicant taking advantage of updated NRC requirements on equipment quality, quantity, and operation. The projected equipment meets NRC regulatory requirements and satisfies the intent of the TMI action item regarding hydrogen concentration monitoring. The justification for the change from Unit 1 equipment, applicable regulatory requirements, work instructions, material requisition forms, and procurement specifications were all reviewed to verify that the intent of the TMI action item was satisfied. Additional field inspection of MCR equipment installation was performed as documented in NRC IIR 05000391/2010605, Section OA.1.4. Specific documents reviewed are listed in the attachment to this report.

b. Observations and Findings

No findings of significance were identified.

c. Conclusions

The inspectors reviewed various completed actions associated with TMI Action Item II.F.1.2.f to verify the adequacy of the applicant's actions. The inspectors concluded that the applicant's efforts were sufficient to satisfy the intent of the respective TMI action item. TMI Action Item II.F.1.2.f is considered closed.

OA.1.13 (Closed) Geotechnical/Foundation Activities Procedure Review (IP 45051)

a. Inspection Scope

The purpose of this IP was to determine if the Watts Bar Unit 2 geotechnical/foundation requirements in the SAR were adequately addressed in the construction specifications and work procedures. A review, called the reconstitution process, of historical NRC inspection reports was completed to determine the status of previously performed inspections in satisfying the requirements specified in the construction inspection procedures. This review was documented in NRC's IIR 05000391/2009602.

Reconstitution of this IP was determined to be unnecessary because the geotechnical/foundation programs, instructions and procedures were common during initial construction of both units, and Unit 1 reconstitution effort confirmed adequate reviews were completed. Unit 1 reconstitution effort was documented in NUREG-1528, "Reconstitution of the Manual Chapter 2512 Construction Inspection Program for Watts Bar Unit 1," Appendix E, "Geotechnical/Foundation Activities."

The majority of the geotechnical/foundation activities were completed during the initial construction period. Based on discussions with TVA, it was concluded that no future geotechnical/foundation work is planned during the current construction phase.

b. Observations and Findings

No findings of significance were identified. The construction specifications and work procedures addressed by this IP were previously inspected under Unit 1 inspection activities. No additional inspections were required for this IP.

c. Conclusions

IP 45051 is considered closed; however, if future work activities arise that are outside of IMC 2517, Watts Bar Unit 2 Construction Inspection Program, the inspectors will inspect those as necessary to satisfy the requirements in this procedure. OA.1.14 (Closed) Geotechnical/Foundation Activities Work Observation (IP 45053)

a. Inspection Scope

The inspectors reviewed Open Item 24 in SSER 18, Appendix HH for WBN Unit 2 which is identified as follows: Based on the extensive layup period of equipment within WBN Unit 2, the NRC staff must review, prior to fuel load, the assumptions used by TVA to re-establish a baseline for the qualified life of equipment The inspectors selected a sample of the applicant's aging calculations for EQ components to verify that the effects of environmental conditions during the layup period were adequately addressed. The inspectors selected the sample to include the majority of EQ components that had been subject to the layup period. Specifically, the inspectors reviewed:

WBNEQ-CABL-064, Material Aging Calculation for Okonite Cables

WBNEQ-MOT-001, EQ Calculation for Westinghouse Motors

WBNEQ-JBOX-001 EQ Binder Tab B, GE Terminal Blocks

GE Memorandum Dated February 24, 1978 Re: Qualification of EB Terminal Board

EDQ00299920110003, Material Aging Calculation to Assess the Impact of the Layup Period on the Unit 2 EQ Cable Qualified

b. Observations and Findings

No findings of significance were identified. The inspectors determined that the applicant utilized the Arrhenius equation, a commonly used formula for the temperature dependence of the reaction rate constant, to determine the effect of the layup period on EQ-qualified life of components and that the thermal values were based on historical plant data and the applicant's heat transfer calculations. The inspectors noted that the effects of radiation and pressure were appropriately not addressed in the aging calculation because the selected EQ components were not exposed to these conditions during the extensive layup period.

c. Conclusions

The inspectors determined that the applicant's EQ calculations evaluated the environmental impact of the extensive layup period on EQ components. The inspectors concluded that the applicant's assumptions for re-establishing a baseline for the qualified life of EQ components were consistently applied and adequate. Therefore, the inspection efforts associated with SSER22 Appendix HH Open Item 18 are complete and closed. OA.1.17 (Closed) SSER 22 Appendix HH: Open Item 19

Therefore, the inspection efforts associated with SSER22 Appendix HH Open Item 19 are complete and closed. OA.1.18 (Closed) Construction Deficiency Report (CDR) 391/81-26 and 391/81-66: Reinspection, Reevaluation & Revision of Pipe Whip and Jet Impingement Protective Devices (PDs) (IP 35007)

a. Inspection Scope

Background: In 1981, the applicant reported to the NRC, in accordance with 10 CFR 50.55(e), deficiencies associated with the documentation, fabrication, and installation of all pipe whip and jet impingement PDs.

The PDs provide protection, as required, to safety systems and components, from the effects of postulated high energy pipe breaks. The nonconformance reports (NCRs)described deficiencies associated with documentation of welding, fit-up, bolting, and PD locations.

Inspection Activities: To address these deficiencies, the applicant reinspected and evaluated all PDs. Weld repairs were made, as required, and all welds were documented. The location was established and the configuration and clearances were verified for all PDs. Anchor bolts were inspected, tested, and documented. A log of all design changes was generated and maintained. Inspection Report 50-390/83-27 and 50-391/83-19 documented the NRC acceptance of the corrective actions, for Unit 1, associated with these NCRs.

The inspectors observed walk-downs of seven randomly selected Unit 2 PDs. The PDs were associated with four different systems at three different locations. The inspectors observed numerous measurements at each PD against the design drawings. All attributes associated with welds, fit-up, bolting, and PD locations were found to be within design tolerances.

The inspectors reviewed the applicant's Unit 2 closure package form NGDC PP 2 with tracking document PER 172651. Documents reviewed are listed in the attachment.

b. Observations and Findings

No findings of significance were identified.

c. Conclusions

The documents reviewed and PDs inspected for CDR 391/81-26 and 391/81-66 met the requirements of 10 CFR 50, Appendix B. This item is closed.
