NTTF Recommendation 2.3: Seismic Response Report Watts Bar Unit 1

1. Executive Summary As a result of the Fukushima Daiichi Nuclear Power Plant accident, the U.S. Nuclear Regulatory Commission (NRC) required all US nuclear power plants to perform seismic walkdowns to identify and address degraded, non-conforming or unanalyzed conditions and to verify the current plant configuration with the current seismic licensing basis.

The NRC Near-Term Task Force (NTTF) issued a report (Reference 1) that made a series of recommendations. Subsequently, the NRC issued a 50.54(f) Letter (Reference 2) that requests information to assure that these recommendations are addressed by all U.S. nuclear power plants. This report provides guidance for conducting a seismic walkdown as required in the 50.54(f) Letter, Enclosure 3, Recommendation 2.3: Seismic. In support of conducting the NTTF-2.3 Seismic Walkdowns, the Electrical Power Research Institute (EPRI) issued a report entitled Seismic Walkdown Guidance (Reference 3) to provide instruction for uniform seismic walkdowns of all U.S. nuclear power plants. This document also includes guidance for reporting the findings of the required walkdowns. At Unit 1 of the Watts Bar Nuclear Power Plant, a total of 120 general Seismic Category I equipment items were selected from the original IPEEE Safe Shutdown Equipment List (SSEL) to fulfill the requirements of the NTTF-2.3 Seismic Walkdowns. The selected items were located in various environments and included many different types of equipment from multiple safety shutdown systems. A total of 49 areas were included for area walk-bys. The equipment walkdowns and area walk-bys were performed by two teams, each consisting of two seismic engineers and operations personnel, between July 16, 2012 and August 15, 2012. All 120 equipment items in the Seismic Walkdown Equipment List (SWEL) were completed during the walkdown phase. Eleven potential adverse seismic conditions were found and addressed through the TVA Corrective Action Program. Page 4 of 451

2. Seismic Licensing Basis The seismic licensing basis for the Watts Bar Nuclear Power Plant is derived from Reference 4 - Watts Bar Nuclear PlantLiving Final Safety Analysis Report Amendment 9.

2.1. General Plant Description The Watts Bar Nuclear Power Plant site is located on a tract of approximately 1770 acres in Rhea County on the west bank of the Tennessee River at river mile 528. The site is approximately 1-1/4 miles south of the Watts Bar Dam and approximately 31 miles north-northeast of the Sequoyah Nuclear Plant. The 1770 acre reservation is owned by the United States and is in the custody of TVA. Also located within the reservation are the Watts Bar Dam and Hydro-Electric Plant, the Watts Bar Steam Plant, the TVA Central Maintenance Facility, and the Watts Bar Resort Area. The plant is designed, built, and operated by TVA. The unit employs a four-loop Pressurized Water Reactor Nuclear Steam Supply System (NSSS) furnished by Westinghouse Electric Corporation. The unit is similar to those of the Sequoyah Nuclear Plant and other similar Westinghouse plants licensed by the U. S. Nuclear Regulatory Commission. The Watts Bar Nuclear Power Plant was designed to meet the intent of the "Proposed General Design Criteria for Nuclear Power Plant Construction Permits" published in July, 1967. The Watts Bar construction permit was issued in January, '1973. This UFSAR, however, addresses the NRC General Design Criteria (GDC) published as Appendix A to 10 CFR 50 in July, 1971, including Criterion 4 as amended October 27, 1987. 2.2. Ground Response Spectra The Watts Bar Nuclear Power Plant is located in the Southern Appalachian Tectonic Province. The Giles County, Virginia, earthquake of 1897, rated as an MMVIII, was assumed to occur at the site for purposes of defining the SSE. Vibratory ground motions are defined by two sets of site seismic design response spectra: the Modified Newmark Ground Response Spectra or Original Site Design Response Spectra for Set A and Set C analyses and the Site Specific Ground Response Spectra for Set B analyses. Set B in-structure response spectra were developed using updated seismic analysis building models and the site-specific ground response spectra. The Set B in-structure response spectra are used for verification of existing plant features. Set C in-structure response spectra were developed using the original Set A ground response spectra and the updated seismic analysis building models that were developed for Set B. The envelope of Set B and Set C in-structure response spectra are termed set B+C, and these are used for design of new plant features and modification of existing plant features. Page 5 of 451

hNTTF Recommendation 2.3: Seismic Response Report Watts Bar Unit 1 2.2.1. Original Site Ground Response Spectra (Set A & Set C) The original site seismic design response spectra which define the vibratory ground motion of the Operating Basis Earthquake (OBE) and the Safe Shutdown Earthquake (SSE) for rock supported structures are shown in Figures 1 and 2. The maximum rock acceleration for the SSE is 0.18g for horizontal motion and 0.12g for vertical motion. The OBE is equal to one-half the SSE, with maximum horizontal and vertical rock accelerations of 0.09g and 0.06g, respectively.

~i* NTTF Recommendation 2.3: Seismic Response Report Watts Bar Unit 1 2.2.2. Site Specific Ground Response Spectra (Set B) Seismic input motions for the evaluation of existing structures, systems, and components are defined by the top-of-rock SSRS shown in Figures 3 through 5. Peak SSE and OBE top-of-rock accelerations are 0.215g (horizontal SSE), 0.15g (vertical SSE), 0.09g (horizontal OBE), and 0.06g (vertical OBE). to I . I I .U . . l 1 .I-I i

NTTF Recommendation 2.3: Seismic Response Report Watts Bar Unit 1 2.4. Equipment NSSS components and equipment supplied by Westinghouse have been qualified in accordance with the applicable seismic qualification requirements. Seismic qualification requirements for Seismic Category I systems and components are consistent with IEEE Standard 344-1975/Regulatory Guide 1.100 for equipment procured after September 1, 1974, or in accordance with a program which provides as a minimum, qualification to the requirements of IEEE 344-1971 and in addition addresses the guidelines of SRP 3.10. Class I equipment and safety related piping were designed such that stress and deformation behavior were maintained within the allowable limits when subjected to normal operating conditions combined with the seismic effects resulting from the response to the OBE. In addition, the stresses that resulted from normal loads combined with the response to the SSE were limited so that no loss of function occurred, and the capability of making a safe and orderly plant shutdown was maintained. These allowable limits are defined in appropriate design standards including:

4. Selection of Structures, Systems and Components The selection of Structures, Systems and Components (SSCs) for the Recommendation 2.3 Seismic followed the guidelines provided in Reference 3 - The ElectricalPower Research Institute's "Seismic Walkdown Guidance."

4.1. SWEL Selection The development of SWEL 1 began with the Safe Shutdown Equipment List (SSEL) that was developed as part of the Individual Plant Examination for External Events (IPEEE) implementation at Watts Bar, found in Reference 5 - IPEEE Seismic Margin Evaluations- Safe Shutdown Paths and Safe Shutdown Equipment List. This list fulfills the requirements of Screens #1 through #3 found in the EPRI walkdown guidance document. The SSEL was then categorized by unit, location, system, equipment class, and safety function. These categories fulfill the Screen #4 requirements of systems, equipment types, and environments. Safety Function "0 - Support Function" was added in addition to the EPRI guidance to categorize equipment that does not perform one particular safety function but does support all five safety functions. The locations included in the SSEL include the:

   " Control Building
   " Auxiliary Building
   " Reactor Building

Diesel Generator Building
Emergency Raw Cooling Water Pump Station.

The six safety functions are:

0. Support function

1. Reactor reactivity control

2. Reactor coolant pressure control

3. Reactor coolant inventory control

4. Decay heat removal

5. Containment function This categorized list is presented in Appendix B as Base List 1. After separating the data into the previously mentioned categories, a sample was selected from Base List 1 to represent all special considerations that were required by the EPRI Walkdown Guidance. This sample was reviewed and compared to plant documentation to locate any new or modified equipment, also required by EPRI Screen #4.

In accordance with the EPRI guidance, SWEL 1 includes consideration of the importance of the contribution of risk for the SSCs. SWELl was compared to the Core Page 14 of 451

NTTF Recommendation 2.3: Seismic Response Report Watts Bar Unit 1 Damage Frequency (CDF) and Large Early Release Frequency (LERF) Rankings, and any shared equipment was noted. Some of the equipment classes that were listed in the EPRI walkdown guidance were not covered in the original IPEEE SSEL, and therefore are not present in Base List 1. However, in order to include all of the classes of equipment, the scope of the selection was expanded for this seismic walkdown to include other Category I Safety Related equipment for the classes that were not previously covered. SWEL 1 represents the full list of equipment that was selected from Base List 1 and from the Category I equipment list. SWEL 1 can be found in Appendix D. Base List 2, presented in Appendix C, is a complete list of all spent fuel pool systems and equipment. SWEL 2 is derived from this list and includes any equipment or system that could cause rapid drain-down of the pool and accidental exposures of fuel assemblies. After review of spent fuel pool layout drawings and consulting with plant personnel, it was determined that no equipment or system failure could cause rapid drain-down of the pool and accidental exposure of the fuel assemblies. SWEL 2 can be found in Appendix D. 4.2. SWEL Analysis The combined SWEL for Watts Bar Unit 1, which consists of 120 items of equipment, adequately addresses all criteria that were required for the selection of SSCs in the EPRI "Seismic Walkdown Guidance." These criteria include a distribution of environments, systems, safety functions, and classes of equipment. The following items were selected in order to address the new and improved equipment criteria of EPRI Screen #4 for Watts Bar Unit 1: UNID Description WBN-0-XSW-236-68DC2-S 125V DC TRANSFER SWITCH, BATTERY BOARDS 1/11 WBN-O-XSW-236-79DC1-S 125V DC TRANSFER SWITCH, CHARGERS 7S/9S WBN-0-CHGR-236-0001-D 125V VITAL BATTERY CHARGER I WBN-0-CHGR-236-0003-F 125V VITAL BATTERY CHARGER III WBN-0-INV-235-0001-D 120V AC VITAL INSTR INVERTER 0-1 WBN-1-INV-235-0001-D 120V AC VITAL INVERTER 1-1 WBN-1-INV-235-0002-E 120VAC VITAL INVERTER 1-11 WBN-1-INV-235-0003-F 120V AC VITAL INVERTER 1-111 Table 1 - New and Improved Equipment Page 15 of 451

5. Seismic Walkdowns and Area Walk-Bys Guidance for performing the walkdowns and walk-bys required for Fukushima NTTF Recommendation 2.3 Seismic can be found in Reference 3 - The ElectricalPower Research Institute's "Seismic Walkdown Guidance."

The walkdowns and walk-bys were conducted in accordance with this guideline and each was given a final status. If no issues were noted or only housekeeping and minor maintenance issues were noted during a walkdown or walk-by, a YES status was given to the selected piece of equipment or area. If a potentially adverse seismic condition was noted, a NO status was given and a Corrective Action Program (CAP) Entry was written to begin a functional evaluation. If any equipment was inaccessible, or if a portion of an item of equipment was unobservable, an UNKNOWN status was given. It is noted that there were no inaccessible SWEL items at Watts Bar Unit 1. 5.1. Seismic Walkdown Procedure All one hundred and twenty (120) Seismic Walkdowns Checklists (SWCs) were completed at Watts Bar Unit 1. These checklists can be found in Appendix E of this document. The primary types of potentially adverse seismic conditions that were addressed during these walkdowns include:

   " Bent, broken, missing, or loose hardware
   " Corrosion (beyond mild surface oxidation)
   " Visible cracks in surrounding concrete
   " Impact of soft targets
   " Collapsing equipment

Inadequate line flexibility Forty-nine (49) Area Walk-by Checklists (AWCs) were completed at Watts Bar Unit 1.

These checklists can be found in Appendix F of this document. The primary areas of observation for potentially adverse seismic conditions that were considered during these walk-bys include:

   " Anchorage of equipment
   " Cable/conduit raceways and HVAC ducts

Spatial interactions between equipment

   " Flooding/Spray hazards
   " Fire hazards
   " Housekeeping and temporary equipment Anchorage configuration for 55 items of equipment in Watts Bar Unit 1 was verified by drawings and/or calculations.

6. Licensing Basis Evaluations 6.1. Licensing Basis Calculations When a potentially adverse seismic condition was identified at WBN, the condition was entered into the corrective action program. No licensing basis evaluations were performed by the walkdown team per TVA expectations to communicate any potential operability concerns as soon as they were identified. Due to the nature of this process, no calculations were performed by the walkdown team for licensing basis evaluations before the CAP entry was submitted. All licensing basis determinations were performed by WBN engineering on each CAP entry.

Multiple CAP entries were generated during the seismic walkdown process at Watts Bar Unit 1. There were a total of eleven CAP entries that were considered potential seismically adverse conditions. No degraded or non-conforming conditions were found during the course of this walkdown process. 6.2. Potential Seismically Adverse Conditions The potentially seismically adverse seismic conditions summarized above are described in more detail below. 6.2.1. Potential Adverse Seismic Condition 1 During the walkdown for WBN-1-TANK-082-0160-A, it was found that the bottom connection on the south U-bolt connection to the support saddle is not tight to the restraint. On the north U-bolt connection to the support side, the bottom connection is missing the washer. A CAP entry was submitted to correct the loose and missing hardware. 6.2.2. Potential Adverse Seismic Condition 2 During the area walk-by for he Diesel Generator Room D104 (WBN-WB-001) a problem with the 1A-A Air Receiver Tank was noted. Of the two inboard anchor plates, the south anchor plate on the tank is installed such that it is resting inside the saddle. This limits it ability to function properly. A CAP entry was submitted to address the issue and site engineering performed an evaluation. 6.2.3. Potential Adverse Seismic Condition 3 During the walkdown for WBN-0-PNL-278-M026A-A and WBN-0-PNL-278-M012, it was found that one of the four visible connecting bolts on the south side of the bolted joint between MCR panels WBN-0-PNL-278-M012 and WBN-0-PNL-278-M015 was sheared off and one was missing. Two bolts were missing between panels WBN-0-PNL-278-M012 and WBN-0-PNL-278-M026D-B on the south side. A CAP entry was submitted and work was scheduled to replace the missing bolts. Page 18 of 451

hNTTF Recommendation 2.3: Seismic Response Report Watts Bar Unit 1 6.2.4. Potential Adverse Seismic Condition 4 During the area walk-by for room 1105 of the Intake Pumping Station (WBN-WB-010) it was found that temporary scaffolding near ERCW pump 0-PMP-67-32 is not adequately restrained to prevent interaction with the pump motor during a seismic event. Lateral restraint was not provided in one direction at a sufficient height to prevent tipping towards the pump motor. A CAP entry was submitted to address the issue and the scaffolding was removed. 6.2.5. Potential Adverse Seismic Condition 5 During the walkdown for WBN-1-MCC-232-B-B, it was found that a cap plate on a tube steel cable tray support was in direct contact with a conduit collar on the MCC. The conduit number in question was not legible. A CAP entry was submitted to address this issue. 6.2.6. Potential Adverse Seismic Condition 6 During the area walk by in the 480V Board Room 1A (WBN-WB-030) a fire protection sprinkler head deflector was found to be in direct contact with a four inch conduit. The conduit in question is PLC-1709, which runs into 1-JB-282-1770, and is located behind panel 10 of WBN-1-MCC-213-AO01-A. A CAP entry was submitted to address this issue. 6.2.7. Potential Adverse Seismic Condition 7 During the walkdown for WBN-0-DBD-238-0003, in the Main Control Room, a copier was observed in close proximity of the breaker side of the panel. The copier is not restrained and does not meet the overturn criteria that would indicate it would be safe from tipping during a seismic event. Additionally, there is a drawing table in the area that is not restrained but would not cause a risk to the panel. A CAP entry was submitted to address the issue and it will be evaluated by Civil Engineering in the form of a Specific Case Engineering Evaluation. 6.2.8. Potential Adverse Seismic Condition 8 During the area walk by in the Mechanical Equipment Room A924 (WBN-WB-032) a sheared anchor bolt was observed on the 480V Board Room Condenser B-B. All remaining anchor bolts appear to be in good condition with only minor to moderate surface corrosion. A CAP entry was submitted to address this issue. Page 19 of 451

NTTF Recommendation 2.3: Seismic Response Report Watts Bar Unit 1 6.2.9. Potential Adverse Seismic Condition 9 During the walkdown for WBN-0-CHR-031-0036/2-A, significant corrosion was observed on the south pedestal baseplate and anchor bolts. The amount of material reduction was approximately 1/8" or less. The north pedestal had significant corrosion as well. A CAP entry was submitted to address the issue and it was determined that sufficient material exists to meet seismic requirements. It should be noted that the anchorage was not visible during the initial walkdown of the equipment. The condition was observed during a subsequent inspection after the insulation surrounding the baseplate and anchorage was removed. 6.2.10. Potential Adverse Seismic Condition 10 During the walkdown for WBN-0-CHR-031-0049/2-B, significant corrosion was observed on the south pedestal baseplate and anchor bolts. The amount of material reduction was in excess of 1/8". The north pedestal had significant corrosion as well. A CAP entry was submitted to address the issue and it was determined that sufficient material exists to meet seismic requirements. 6.2.11. Potential Adverse Seismic Condition 11 During the walkdown for WBN-0-INV-235-0001-D, the spacing tolerance of +/- 3" is violated between the third and fourth anchor bolts on the front of the inverter. The field measured spacing between these bolts is 9-3/4". Per plant documentation, this spacing should be 1'-1-3/116", which is 3-7/16" greater than the as-installed anchor spacing. The as built dimension for one anchor bolt on the front of WBN-1-INV-235-0003-F does not match plant documentation. Per plant documentation, the first anchor spacing on the right side of the cabinet should be 15-5/8". The dimension in the field was measured to be 18-1/4". A CAP entry was submitted to address these issues and the calculation and drawings shall be revised as necessary to document the acceptability of the as-installed anchorage configuration.

7. IPEEE Vulnerabilities Resolution Report Information for the IPEEE Vulnerabilities Resolution Report is derived from Reference 5

- IPEEE Seismic Margin Evaluations- Safe Shutdown Paths and Safe Shutdown Equipment List. 7.1. IPEEE Description In Generic Letter 88-20, Supplement 4, the US Nuclear Regulatory Commission requested that the utilities for all active nuclear power plants in the United States perform an evaluation of their nuclear power generating facilities to identify any vulnerabilities associated with the occurrence of several plant-specific external events, and to access the impact of these vulnerabilities on the potential for plant core damage or radioactive material release. This program, designated the Individual Plant Examination of External Events (IPEEE), is a corollary program to the Individual Plant Examination (IPE) which focused on the vulnerabilities associated with the occurrence of external events. 7.2. IPEEE Findings and Vulnerabilities For Watts Bar Nuclear Power Plant the Response Level Earthquake (RLE) is specified as a median spectral shape from NUREG/CR-0098 anchored to a peak ground acceleration of 0.3g. Screening and evaluation of outliers is performed at the level of the RLE through the use of scaled existing amplified response spectra. The vertical ground response spectrum for the RLE is taken as 2/3 of the horizontal. The items walked down during the IPEEE program were found to be rugged and robust. The IPEEE walkdowns note whether or not the items could be screened out as a result of the walkdown observations coupled with the walkdown team knowledge of the design basis conservatism's for each item. High confidence low probability of failure (HCLPF) seismic capacity calculations were prepared for items which could not be screened by other means and in all cases, the calculated HCLPF seismic capacities are greater than 0.3g. Table 2 summarizes the WBN HCLPF calculations and results. Page 21 of 451

FACILITY RISK CONSULTANTS, INC. Structural& Seismic Engineering @Risk Management NTTF 2.3/WBN-01 November 12, 2012 PEER REVIEW REPORT Watts Bar Nuclear Plant Unit I Near-Term Task Force 2.3 Seismic Walkdowns A peer review of the Tennessee Valley Authority (TVA) Watts Bar Nuclear Plant - Unit 1 (WBN1) seismic walkdowns for Near-Term Task Force (NTTF) Recommendation 2.3: Seismic was performed in accordance with the U.S. Nuclear Regulatory Commission (NRC) 50.54 (f) letter (listed as Reference 2 in the WBN1 Seismic Response Report) and the guidance provided in Electric Power Research Institute (EPRI) Report 1025286 (listed as Reference 3 in the Seismic Response Report). A highly interactive process was utilized by the peer review team. This involved ongoing open dialog consultation with project participants throughout training, equipment selection, equipment walkdowns, area walkbys, review of potentially adverse seismic conditions and corrective action program documentation, and final report preparation. In summary, the peer review team is in full concurrence with the final results as documented in the WBN1 Seismic Response Report, and we conclude that all of the project requirements have been met and adequately documented. The following sections summarize the details of the peer review process for the major elements of the project. TRAINING The walkdown teams are described in Section 3 of the WBN1 Seismic Response Report. All of the walkdown team members successfully completed the EPRI developed training on NTTF Recommendation 2.3 - Plant Seismic Walkdowns. All of the individual team members meet the qualification requirements as defined in EPRI Report 1025286. In addition to this training, per our recommendations, all walkdown team members received additional training. The purpose of the additional training was two-fold. First, additional technical training was provided on equipment anchorage and seismic interaction evaluations, as an enhancement to the anchorage and interaction issues overview provided in the EPRI training course. Second, background information was provided on the site-specific seismic programs implemented by TVA at WBN1. This provided team members with historical background on the scope and findings of prior seismic reviews, as well as to deepened their understanding of the seismic licensing basis for WBN1. Examples of the additional plant-specific training material provided for the team members include the following:

Description of WBN1 seismic design basis including application of Set B and B+C seismic design response spectra for evaluation of existing plant features and new seismic design activity, respectively.
Overview of WBN1 seismic design criteria for structures, systems, and components and discussion of how to locate calculation packages documenting acceptance.

           - Ongoing enhanced seismic IPEEE efforts to increase plant HCLPF capacity SELECTION OF ITEMS ON THE SEISMIC WALKDOWN EQUIPMENT LIST (SWEL)

The completed SWEL as described in Section 4 of the WBN1 Seismic Response Report is in full compliance with the guidelines in EPRI Report 1025286. The SWEL 1 represents a diverse sample of selected equipment and support systems required to perform the five safety functions of reactor reactivity control, reactor coolant pressure control, reactor coolant inventory control, decay heat removal, and containment function. The SWEL 1 includes, as appropriate, various types of systems, classes of equipment, and equipment environments. The SWEL 1 includes new and replacement equipment. The WBN1 IPEEE review was performed using the EPRI margins methodology and that success path based SSEL was used as a starting point for SWEL 1. No seismic PRA has been performed for WBN1 so no information regarding dominant contributors to seismic risk was available. SWEL 1 was compared to the Core Damage Frequency (CDF) and Large Early Release Frequency (LERF) Rankings, and any shared equipment was noted. The SWEL 2 represents selected equipment related to the spent fuel pool system, including those that could cause rapid drain-down of the pool and accidental exposures of the fuel assemblies. There was considerable interaction between the peer review team, the walkdown team, and the equipment selection team during the course of the evaluation. The final SWEL, as documented in Section 4 and in Appendix D of the WBN1 Seismic Response Report, is a culmination of this Page 446 of 451 FACILITY RISK CONSULTANTS, INC.

NTTF 2.3/WBN-01 November 12, 2012 Page 3 of 7 interaction. Examples of peer review comments that were adequately addressed and resolved during the SWEL development process include the following:

In the preliminary SWEL, the safety functions were not listed for each item of equipment.

This made it very difficult to ensure that all five safety functions were adequately represented. The team updated the list to clearly include the respective safety functions.

Based on review of the update list from the above comment, it was discovered that the reactor pressure control safety function was not adequately represented on the preliminary SWEL. It was recommended that the team add additional equipment items representative of the reactor coolant pressure control safety function. Items were added as indicated in the final SWEL
In order to include representative equipment items for all of the 21 classes of equipment listed in Table B-1 of the EPRI Report 1025286, items of equipment were added to the SWEL that were not part of the IPEEE review. It was noted that this was unnecessary yet conservative, so the items remained on the SWEL.
In the preliminary SWEL there was confusion regarding the equipment class definition of distribution panels, and low and medium voltage switchgears. This is corrected in the final SWEL, such that the 120V vital instrument power board is in the distribution panel equipment class, and the 480V shutdown boards are in the low voltage equipment class.
It is noted that the final SWEL adequately includes equipment in each major building structure and encompasses mild to more severe environments.
It is noted that there were no outliers in the WBN1 seismic IPEEE review, so there were no items of equipment that had to be added to the SWEL for confirmation of seismic IPEEE upgrades.

SEISMIC EQUIPMENT WALKDOWNS AND AREA WALKBYS The peer review team spent considerable time interfacing with the walkdown team members during the WBN1 seismic equipment walkdowns and area walkbys. This included responding to questions regarding the scope and content of the reviews. This also included in-plant observations of the teams during the reviews as well as independent in-plant reviews of individual equipment components. Walkdown observations and results were reviewed and discussed on a weekly basis with the walkdown team members. Particular emphasis was given to any items preliminarily identified as potential adverse seismic conditions (see discussion in the next section). In the end, the peer review addressed over 50% of the completed walkdown documentation forms. It is noted that the in-plant activity and over 50% documentation review is above and beyond the peer review requirements as defined in EPRI Report 1025286. As a result of this effort, we are highly confident that the teams conducted the reviews in a thorough and competent manner, and that the reviews are fully in compliance with the intent of the NRC 50.54 (f) letter. Examples of seismic issues discussed and resolved during the course of the peer review process for the WBN1 equipment seismic walkdowns and area walkbys include the following:

On the RHR Pump Room Cooler 11B-B, it was confirmed that the anchorage had only minor surface rust that would not significantly impact capacity. Also, it was concluded that proximity interaction with a nearby small bore pipe was credible but not significant.

Page 447 of 451 FACILITY RISK CONSULTANTS, INC.

NTTF 2.3/WBN-01 November 12, 2012 Page 4 of 7

On the ERCW Strainer 1A-1, minor surface rust was judged to be acceptable, and proximity interaction due to vertical contact with a scaffolding pole was determined to not be significant due to massive size of strainer.
On the ERCW Pump A-A, the walkdown team observed that overhead scaffolding was in close proximity to a level indicator, but it was determined that the scaffolding is rigidly restrained and that the impact was not credible. Also, close proximity of an electrical conduit and a pre-lube throttle was deemed to be credible, but not significant, so accepted as-is.
A civil/structural feature was observed to be in close proximity (3/4" to 1") to 1-FCV-062-0093. Based on closer review, the clearance was found to be sufficient and the interaction was not credible.
Minor cracking of concrete was observed by the walkdown team at DG 1A-A Room Exhaust Fan 1A anchor bolts. The cracking in proximity to the anchors was determined to be less than 0.5mm and judged to not be a seismic concern.

" The corrosion noted by the walkdown on anchor bolts for the 480V BD Room 1A Supply AHU 1A-A was determined to be only minor surface rust and accepted. In addition, the close proximity of a cable tray support member to the AHU was determined to have sufficient clearance and was determined to be non-credible.

The walkdown team observed a potential seismic interaction flexibility concern at Electrical Board Room Chiller B-B. A 2" pipe penetrating the permanent hood continued to a rigid attachment to a 1" pipe. The screening tools in WB-DC-20-32 were implemented and the flexibility was determined to be adequate.
Scaffolding was observed by the walkdown team to be in close proximity to the 125V Vital Battery Board I Panel 1. Based upon further review, the 3/4" clearance was determined to be sufficient to preclude the interaction.
On the 125V DC Transfer Switch Select Chargers 7S/9S, the walkdown team observed that two conduit interfaces had hard connections and questioned whether flex conduit should have been used. After further consideration including implementation of screening tools from WB-DC-20-32, the configuration was determined to be acceptable.

" Minor hairline cracking at the grounding bus connection bolt for 125V Diesel Generator Battery 1B-B was identified by the walkdown team. No significant cracks were in the vicinity of the anchors and the condition was determined to not be a potential adverse seismic condition. " Temperature sensors lacking a safety cable were identified by the walkdown teams for several items of equipment. After more detailed assessment utilizing Seismic Category I(L) screening criteria of WB-DC-20-32 and WCG-2-409, these were determined to not represent a failing and falling concern.

During the walk-by of area A851 WBN-WB-030, a cable tray support end cap was found to be in close proximity to a conduit exiting MCC-213-A2. Based on the screening tools in WB-DC-20-32, the clearance was found to be adequate.
During the walkby of area A306 WBN-WB-042, 1" clearance was observed between a flow control valve and adjacent pipe support steel. Based on the screening tools in WB-DC-20-32, the clearance was found to be adequate.

NTTF 2.3/WBN-01 November 12, 2012 Page 5 of 7 In the end, the peer review team is in concurrence with the Seismic Walkdown Checklists (SWCs) and Area Walkby Checklists (AWCs) as presented in Appendices E and F, respectively, of the WBN1 Seismic Response Report. POTENTIAL ADVERSE SEISMIC CONDITIONS The peer review team spent considerable time with the walkdown teams addressing preliminary potential adverse seismic conditions identified during walkdowns. It is noted that there were very many questions early in the walkdown review process on the conservative side of issues, and these kinds of questions diminished towards the end of the project as the judgment of the teams significantly improved. Most of these early concerns were in regards to potential seismic interaction effects. In most cases, these issues were resolved by review of prior evaluations or the TVA procedures and guidance already in place at the plant. All potential adverse seismic conditions were reviewed in detail, including working with the teams to address seismic licensing basis and operability issues for the confirmed potential adverse seismic conditions that resulted in the initiation of Problem Evaluation Reports (PERs) as part of the Corrective Action Program (CAP). In the end, the peer review team is in full concurrence with all of the potential adverse seismic conditions summarized in Section 6.2 of the WBN1 Seismic Response Report. Comments regarding the individual potential adverse seismic conditions for WBN1 include the following:

Potentially Adverse Seismic Condition 1 addresses a U-bolt connection that was not tight on the Diesel Generator Engine 1A1 Start Air Receiver A. In our opinion the loose connection still provides an adequate load path for design basis seismic effects. The walkdown team conservatively noted this as a potential adverse seismic condition and entered it into the CAP.
Potentially Adverse Seismic Condition 2 addresses a similar issue noted during the walkby for Diesel Generator Room D104, where an air receiver tank is not properly aligned. We judged that that the existing configuration still provided an adequate load path for design basis seismic effects. The walkdown team conservatively noted this as a potential adverse seismic condition and entered it into the CAP.
Potentially Adverse Seismic Condition 3 addresses missing and damaged bolts connecting adjacent Diesel Generator system I&C panels. Although the present bolts were determined to be adequate to hold the adjacent panels together, the walkdown team conservatively noted this as a potential adverse seismic condition and entered it into the CAP.
Potentially Adverse Seismic Condition 4 addresses a temporary scaffold near ERCW Pump 0-PMP-67-32 (area walkby) as a seismic interaction concern. The pump was determined to be sufficiently rugged that the potential interaction was not significant.

The walkdown team noted the non-conforming scaffold as a potential adverse seismic condition and entered it into the CAP.

Potentially Adverse Seismic Condition 5 addresses a cable tray support cap plate in contact with a conduit collar on 1-MCC-232-B-B. Detailed inspections ascertained that the adjacent MCC cubicles falling within a vertical 45 degree line of the impact location Page 449 of 451 FACILITY RISK CONSULTANTS, INC.

NTTF 2.3/WBN-01 November 12, 2012 Page 6 of 7 were free of safety-related plant features. The walkdown team noted this as a potential adverse seismic condition and entered it into the CAP. Potentially Adverse Seismic Condition 6 addresses a fire protection sprinkler head in contact with a conduit in the 480V Board Room 1A (area walkby). This represents a potential water spray hazard for equipment in the area. The walkdown team noted this as a potential adverse seismic condition and entered it into the CAP. The PER review by plant operations concluded that it did not affect plant safety, and a non-essential priority work order was forwarded to plant fire protection for later resolution. The basis for the disposition of the PER was not clear. Based on our recommendations, another CAP entry was initiated to enable a more thorough review of the configuration. This corrective action is currently in process.

Potentially Adverse Seismic Condition 7 addresses an unrestrained copy machine in the vicinity of a control room panel. It is our judgment that the seismic accelerations and configuration geometry preclude overturning, and operations concluded that the potential impact condition to the panel did not adversely impact the functionality of the affected equipment. The walkdown team noted the non-conforming copy machine as a potential adverse seismic condition and entered it into the CAP.
Potentially Adverse Seismic Condition 8 addresses a sheared off anchor bolt on 480V Board Room Condenser B-B (from the area walkby). The remaining bolts were judged to possess sufficient capacity for adequate anchorage of the component. The walkdown team conservatively noted this as a potential adverse seismic condition and entered it into the CAP.
Potentially Adverse Seismic Condition 9 addresses significant corrosion on the anchorage and base pedestal of Shutdown Board Room Chiller A-A. There is evidence of some material reduction. The remaining material was determined to possess adequate margin to resist design basis seismic loads. The walkdown team noted this as a potential adverse seismic condition and entered it into the CAP.

   "  Potentially Adverse Seismic Condition 10 addresses significant corrosion on the anchorage and base pedestal of Shutdown Board Room Chiller B-B. There is evidence of some material reduction. The remaining material was determined to possess adequate margin to resist design basis seismic loads. The walkdown team noted this as a potential adverse seismic condition and entered it into the CAP.

Potentially Adverse Seismic Condition 11 addresses anchor spacing not in compliance with design output documentation for 120V AC Vital Inverters 0-1 and 1-111. The anchorage is robust and meets design basis seismic requirements by inspection, but is outside of the dimension tolerance on the drawings. The walkdown team conservatively noted this as a potential adverse seismic condition and entered it into the CAP.

SUBMITTAL REPORT The peer review team has reviewed the WBN1 submittal report in detail and we are in full concurrence with the documented observations and findings. The report is in compliance with the guidance in EPRI Report 1025286 and meets the requirements and objectives of the NRC 50.54 (f) letter. Page 450 of 451 FACILITY RISK CONSULTANTS, INC.

NTTF 2.3/WBN-01 November 12, 2012 Page 7 of 7 In our opinion, the potential adverse seismic conditions identified by the program are in general only minor issues, and this is a reflection of the adequate seismic design criteria as well as the seismic-related construction and maintenance procedures that TVA has in place at WBN1. Further evaluation is ongoing for Potential Adverse Seismic Condition 6 as noted above. Sincerely, i1onU Stephen J. Eder, P.E. John 0. Dizon, P.E.
