rrr NTTF Recommendation 2.3: Seismic Response SequoyahReport Unit 2

1. Executive Summary As a result of the Fukushima Daiichi Nuclear Power Plant accident, the U.S. Nuclear Regulatory Commission 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 2 of the Sequoyah Nuclear Power Plant, a total of 119 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 systems. A total of 50 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 13, 2012 and November 9, 2012.

All 119 equipment items in the Seismic Walkdown Equipment List (SWEL) were completed during the walkdown phase. Ten potentially adverse seismic conditions were found and addressed through the TVA Corrective Action Program.

2. Seismic Licensing Basis The seismic licensing basis for the Sequoyah Nuclear Power Plant is derived from Reference 4 - Sequoyah Nuclear Plant Living Final Safety Analysis Report Amendment 24.

2.1. General Plant Description The Sequoyah Nuclear Power Plant site is located near the geographical center of Hamilton County, Tennessee, on a peninsula on the western shore of Chickamauga Lake at Tennessee River mile (TRM) 484.5. The Sequoyah site is approximately 7.5 miles northeast of the nearest city limit of Chattanooga, Tennessee, 14 miles west-northwest of Cleveland, Tennessee, and approximately 31 miles south-southwest of TVA's Watts Bar Nuclear Power Plant. The plant has been designed, built, and is operated by TVA and contains two identical units. Each of the two units employs a Pressurized Water Reactor Nuclear Steam Supply System with four coolant loops, furnished by Westinghouse Electric Corporation. Unit 2 began commercial operation on June 1, 1982.

2.2. Ground Response Spectra The seismic design basis for Sequoyah Nuclear Power Plant is the 0.18g horizontal peak ground acceleration represented by the modified Housner-shape spectrum for Safe Shutdown Earthquake (SSE). Operating Basis Earthquake (OBE) is one-half of SSE ground acceleration. Vertical ground acceleration is two-thirds of the horizontal ground acceleration.

Figure 1 illustrates the relationship between the 5% damped minimum design response spectra and the actual site seismic design response spectra for the SSE used in the design of rock-supported structures.

fi* NTTF Recommendation 2.3: Seismic Response Report Sequoyah Unit 2 Seismic Category I mechanical equipment has been qualified in accordance with the applicable seismic qualification requirements contained in Reference 4.

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. The 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 walkdowns followed the guidelines provided in Reference 3 - The Electrical Power 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 Sequoyah, found in Reference 5 - Seismic Capability Walkdown for IPEEE. 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 Damage Frequency (CDF) and Large Early Release Frequency (LERF) Rankings, and any shared equipment was noted.

Page 11 of 444

i71 NTTF Recommendation 2.3: Seismic Response Report Sequoyah Unit 2 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 Sequoyah Unit 2, which consists of 119 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 Sequoyah Unit 2:

5. Seismic Walkdowns and Area Walk-Bys Guidance for performing the walkdowns and walk-bys required for Fukushima NTTF Recommendation 2.3 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. Ifa potentially adverse seismic condition was noted, a NO status was given and a Corrective Action Program (CAP) entry was written. 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 Sequoyah Unit 2.

5.1. Seismic Walkdown Procedure One hundred and nineteen (119) Seismic Walkdowns Checklists (SWCs) were completed at Sequoyah Unit 2. 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 that is more than moderate

• Visible cracks in surrounding concrete

" Impact of soft targets

• Collapsing equipment

" Inadequate line flexibility Fifty (50) Area Walk-by Checklists (AWCs) were completed at Sequoyah Unit 2. 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 Sequoyah Unit 2 was verified by drawings and/or calculations.

irr NTTF Recommendation 2.3: Seismic Response Sequoyah Report Unit 2 For cabinets and panels that were selected for walkdown, NRC guidance was followed to determine which could and could not be opened for internal inspection. Undue safety hazards, operational hazards, or cabinets that required extensive disassembly were documented and only observable anchorage was included in those walkdowns.

5.2. SWC & AWC Summary The results documented by the SWCs and AWCs for Sequoyah Unit 2 is summarized below:

6. Licensing Basis Evaluations 6.1. Licensing Basis Calculations When a potentially adverse seismic condition was identified at SQN, 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 SQN engineering on each CAP entry.

Multiple CAP entries were generated during the seismic walkdown process at Sequoyah Unit 2. There were a total of ten 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. Potentially Adverse Seismic Condition 1 During the walk-by for the Surge Tank B Area, a Radiation Control Cabinet was found chained at a single point to a steel column. To prevent sliding or tipping into the air compressor, it was recommended that the cabinet be anchored in a second location. A CAP entry was submitted to address this issue, and the cabinet was secured to prevent movement during a seismic event.

6.2.2. Potentially Adverse Seismic Condition 2 A temporary cooling fan was noted to be improperly restrained in the 480V Board Room 2A. This fan was secured with a chain to an appropriate structure, but the restraint was in a location that would allow the fan to move and tip in a manner that could cause it to strike a nearby electrical cabinet, 2-BDC-201-GM-A. Since many of the relays contained in this cabinet are sensitive, this condition was considered to be potentially seismically adverse. A CAP entry was submitted to address this issue and the fan was removed.

571 NTTF Recommendation 2.3: Seismic Response Report Sequoyah Unit 2 6.2.3. Potentially Adverse Seismic Condition 3 During the walkdown for equipment in the 125V Vital Battery Room IV and the 480V Board Room 2B, a crack was noted in a common masonry block wall. The crack was observed at the top of the wall, directly beneath the steel angle used to connect the wall to the ceiling. The crack is approximately 6' long and was visible on both sides of the masonry wall. This crack was judged to pose a potentially adverse seismic condition to three different items of equipment including the 120V AC Vital Inverter 2-IV and 125V DC Vital Battery Charger IV in the 480V Board Room and battery racks 1-20 and 21-40 in the 125V Vital Battery Room IV. A CAP entry was submitted to address the issue and the wall was deemed adequate to perform its intended function.

6.2.4. Potentially Adverse Seismic Condition 4 During the equipment walkdown for SQN-2-LOCL-500-0222B and the area walk-bys for Area 25 - RHR Pump Area, Area 38 - Auxiliary Feed water Pump B Area, and Area 43 -

SI Pump Area, it was noted that 55-gallon drums in the vicinity of the equipment were not properly restrained. Per TVA Procedure, the geometry of these drums require seismic restraint. A CAP entry was submitted to address the issue and the drums were removed from the affected areas.

6.2.5. Potentially Adverse Seismic Condition 5 During the area walk-by associated with 125V Battery Room Ill, it was observed that the sink cabinet in this room was not restrained. During a seismic event, the cabinet could move away from the wall, causing the water supply line to rupture and cause a spray hazard onto the battery racks. A CAP entry was submitted to address this issue and a calculation was found that determined the unrestrained cabinet is not a seismic concern and would not cause a spray hazard in case of a seismic event. No further action required.

6.2.6. Potentially Adverse Seismic Condition 6 An anchor bolt was noted to be missing from a duct support above the Control Rod Drive Generator 2B (2-GEND-085-DH/3B) in the Control Rod Drive Mechanism Room.

The duct support with the missing bolt is a frame support, cantilevered from the wall, with two baseplates connecting it to the concrete. These baseplates have four bolt holes each, one of which is missing a bolt in the top plate. A CAP entry was submitted to address this issue and the support was deemed adequate to perform its intended function.

Page 16 of 444

EiI NTTF Recommendation 2.3: Seismic Response Report Sequoyah Unit 2 6.2.7. Potentially Adverse Seismic Condition 7 A scaffold with potentially inadequate restraint was noted in the 6.9kV Shutdown Board Room B. This scaffolding was found in front of compartments 10 and 11 of the Unit 2 6900V Shutdown Board (2-BDB-202-CP) and was observed to be anchored at only one point by a loosely hung chain and could tip into overhead lighting and the shutdown board. A CAP entry was submitted to address this issue. The scaffolding was later observed to be adequately restrained on its upper corner to a permanent pipe support cantilevered from the ceiling. No further action required.

6.2.8. Potentially Adverse Seismic Condition 8 During the area walk-by of the ECRW Pump Room 2A-A, a flammable materials cabinet was noted to have a broken latch on its door. It was also not anchored to the floor or wall. During a seismic event, the door could open or the cabinet could tip, causing the enclosed flammable material to spill from the cabinet. This would present a potential fire hazard in the area. A CAP entry was submitted to address this issue and a hasp and lock was verified to have been installed by mechanical maintenance. No further action required.

6.2.9. Potentially Adverse Seismic Condition 9 While performing the walk-by for the Control Building El. 669 Mechanical Room, a bolt and nut were observed to be not fully engaged on a System 26 Fire Protection pipe hanger. The hanger is located 12 feet above the floor, on the east side, between the A and B EBR AHU's, just above the cross connection between the AHU's, closer to the A AHU. A CAP entry was submitted to address the issue and the pipe hanger was deemed adequate to perform its intended function and was corrected by work order.

6.2.10. Potentially Adverse Seismic Condition 10 While performing the walkdown for the Rod Drive Cooling Unit C-A, SQN-2-AHU-030-0088, a missing bolt was observed that connects the cooling unit to the steel support frame. A CAP entry was submitted to address the issue and work is planned to replace the missing bolt.

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

- Seismic Capability Walkdown for IPEEE and Reference 6 - Sequoyah Nuclear Plant (SQN) - Units I and 2 - Response to Request for Additional Information on the Individual Plant Examination of External Events.

7.1. IPEEE Description In Generic Letter 88-20, Supplement 4, the US Nuclear Regulatory Commission (NRC) 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.

After NRC review of the Sequoyah IPEEE Report, it was found that the review level earthquake (RLE) was characterized in a manner that was inconsistent with NUREG-1407, the governing document for IPEEE seismic events. The intent of NUREG-1407 is that the RLE control motion for SQN (which is predominantly a rock site) should be specified at rock outcrop as the NUREG/CR-0098 median 5% damped spectral shape for rock, anchored to a PGA of 0.30g at rock outcrop. The SQN IPEEE appropriately specified the RLE spectral shape as the NUREG/CR-0098 median rock spectrum at rock outcrop, but inappropriately specified the RLE PGA of 0.30g as occurring at the free-field soil surface.

7.2. IPEEE Findings and Vulnerabilities The IPEEE Report for the Sequoyah Nuclear Plant addressed multiple vulnerabilities that were identified during the original IPEEE walkdown process. A full list of these vulnerabilities can be found in Reference 5 - Seismic Capability Walkdown for IPEEE.

A sample of this list was selected for Recommendation 2.3 walkdowns, and this equipment was added to the SWEL for Sequoyah Unit 2. These selected items of equipment, the issues noted, and the resolutions can be found in Table 2.

NRC IPEEE Review Subsequent to these original SQN high confidence low probability of failure (HCLPF) capacity bounding evaluations and during the NRC Request for Additional Information (RAI) process related to the definition of RLE control motion, the SQN IPEEE RLE was redefined from the free-field soil surface to rock outcrop. As a result, all of the HCLPF capacities as determined by the conservative bounding evaluations were scaled down by a factor of 0.75. Due to this scaling, the HCLPF capacity for many items dropped to below 0.30g (for RLE defined at rock outcrop). However, at that time no additional effort was expended to review in more detail and improve (increase) these HCLPF capacities, especially by eliminating some of the simplifying conservative approximations as used in the original bounding evaluations.

1. Does anchorage of equipment in the area appear to be free of YZ NEI U[I N/AZ potentially adverse seismic conditions (if visible without necessarily opening cabinets)?

It was noted that a few of the HVAC supports attached to the ceiling had at first appearedto have missing bolts. The HVAC base plates consisted of a 4 bolt pattern plate bolted to the ceiling. Not all of the bolts had been installed. In the location without the bolts the cornerof the base plate was welded to an embed plate. In most cases only one bolt was missing. Given that there was a comer weld to account for the missing bolt as well as the robustness of the connection (even when neglecting the weld) compared to the size of the ductwork this is deemed to be acceptable.

The posts supporting the two sets ofstairs to the elevated office are poorly anchored. The posts are not anchoredto the floor and bolts are missing between the posts and upperplatforms. A temporaryganty crane, with locked wheels, is anchoredto one of these posts. Since there is no equipment related to safe shutdown or operations in the area, this issue is not consideredseismically adverse.

There is moderate mineral buildup /corrosion on conduit (and associatedanchorage),conduit support steel baseplate, and electrical cabinet behindpipe on wall near 0-CHR-311-171.

There appearsto be some type of leak near the ceiling. This condition is not considered to be seismically adverse, but it should be monitoredforfuture degradation.

Control Bldg Elec Bd Rm Alt Fan A-A Mtr (O-MTRB-311-0027) has one mounting nut that is notfully engaged (appearsto be about 50% engaged). The loose nut is on one (of two) of the all thread rods at the base of the motor mountingframe (on the mounting rod that does not have a sleeve). This is not considered to be seismically adverse because it appearsthat this condition has not developedfrom the nut "backing off' (or any other kind of damage). It appears that this condition is the result of the base rod being too short.

FACILITY RISK CONSULTANTS, INC.

Structural& Seismic Engineering &Risk Management NTTF 2.3/SQN-02 November 12, 2012 PEER REVIEW REPORT Sequoyah Nuclear Plant Unit 2 Near-Term Task Force 2.3 Seismic Walkdowns A peer review of the Tennessee Valley Authority (TVA) Sequoyah Nuclear Plant - Unit 2 (SQN2) 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 SQN2 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 SQN2 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 SQN2 Seismic Response Report. All of the walkdown team members successfully completed the EPRI developed training on NTTF Recommendation 2.3 - Seismic Walkdown Guidance. All of the individual team members meet the qualification requirements as defined in EPRI Report 1025286. In addition to this EPRI 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 SQN. This provided team members with historical background on the scope and findings of prior seismic reviews, as well as to deepen their understanding of the seismic licensing basis for SQN.

Examples of the additional plant-specific training material provided for the team members include the following:

• Description of SQN seismic design basis 0.18g Housner-shaped ground motion response spectrum

• Scope of the Nuclear Performance Plan (NPP, NUREG 1232, Volume 2) commitments at SQN. This included the following major civil/seismic programs:

- Scaffolding -- MMTP-102

- Seismic Interaction Commodity Clearance Requirements -- M&AI-28 and N2C-948 SELECTION OF ITEMS ON THE SEISMIC WALKDOWN EQUIPMENT LIST (SWEL)

The completed SWEL as described in Section 4 of the SQN2 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 SQN IPEEE review was performed using the EPRI margins methodology and that success path based SSEL associated with SQN2 was used as a starting point for SWEL 1. No seismic PRA has been performed for SQN2 so no information regarding dominant contributors to Page 439 of 444 FACILITY RISK CONSULTANTS, INC.

NTTF 2.3/SQN-02 November 12, 2012 Page 3 of 7 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 SQN2 Seismic Response Report, is a culmination of this interaction. Examples of peer review comments that were adequately addressed and resolved during the SWEL development process include the following:

• During the development of the preliminary SWEL, there was confusion regarding the equipment class definition, in particular, instrument racks (18), temperature sensors (19),

distribution panels (14) and medium voltage switchgears (03). These were clarified and corrected in the final SWEL. As such, the 120VAC vital instrument power boards are in the distribution panel equipment class, and the 6.9kV shutdown boards are added to the medium voltage switchgear equipment class.

• 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.

• During the initial phase of the SWEL development, it was noted that no equipment were selected inside the Reactor Building. Subsequently, selected equipment items in the Reactor Building were added to the final list.

" Selected SQN2 equipment items identified as outliers in SQN seismic IPEEE review were added to the SWEL for confirmation of seismic IPEEE upgrades. This is to address reporting of the evaluations related to seismic vulnerabilities identified during that program.

" It is noted that the final SWEL adequately includes equipment in each major building structure and encompasses mild to more severe environments.

SEISMIC EQUIPMENT WALKDOWNS AND AREA WALKBYS The peer review team spent considerable time interfacing with the walkdown team members during the SQN2 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 Page 440 of 444 FACILITY RISK CONSULTANTS, INC.

NTTF 2.3/SQN-02 November 12, 2012 Page 4 of 7 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 walkdown team observations and seismic issues discussed and resolved during the course of the peer review process for the SQN2 equipment seismic walkdowns and area walkbys include the following:

• The walkdown teams diligently verified presence of safety cables or wires on miscellaneous overhead features (such as lights and speakers) and spring locks on florescent light tubes for all electrical equipment panels. Any exceptions were carefully reviewed and discussed.

• The walkdown teams diligently noted all cracks including minor hairline cracks in floors in the vicinity of equipment and even in structural walls. Each instance was discussed at length and resolved, and no items were found to be significant. For the masonry walls, all of cases were verified to be Seismic Category I reinforced block wall structures, and that hairline cracks were insignificant.

• The walkdown teams diligently verified seismic adequacy issues associated with equipment anchor condition and anchorage load path, such as bent, missing or loose hardware, anchor edge distance and rust conditions. Each instance was reviewed and discussed thoroughly. Conditions were generally determined to be insignificant, thus did not affect seismic capacity and were accepted as-is. Others were qualified as-is based on existing documentation.

• The walkdown teams diligently noted instances of unusual supports on overhead systems, such as bent rod hangers and missing anchor bolts. Based on further discussion, in all cases it was determined that the vertical load carrying capability of the overhead supports was not compromised, thus did not pose as a seismic falling interaction hazard.

• The walkdown teams diligently noted instances of potential seismic interaction sources to assess their effects on the nearby safety related equipment items. Examples include fire extinguishers, frisker on unanchored table, unanchored barrier posts and cantilevered fire barrier wall. Based on further discussion and review, in all cases it was determined that the potential source was either evaluated and qualified previously as documented in calculation, or deemed to be insignificant.

• At the DG 2A-A Battery Rack, the walkdown teams noted an emergency eye wash station was not adequately restrained and could potentially roll and topple over during a seismic event and spill or spray water in the room. This was determined not to represent a significant hazard to the batteries, but the eye wash was subsequently restrained.

• The skids for each of the diesel generators were inspected in detail by the walkdown teams, and they had preliminary concerns that the base frames for the engine and the generator were not linked together by steel members as shown on the original design drawings. After considerable discussion and reviewing the load paths, it was concluded that the base frames are very rigid, and that these are each anchored to the same rigid massive concrete base, so that it was not possible for the engine and the generator to experience any differential seismic movement.

" On electrical panel line-up inspections, the walkdown teams checked for bolting between adjacent panels. In one case, for the DG 2A-A Control Panel, they observed that 1 of 8 bolts was missing in the cabinet-to-cabinet connection. It was agreed that the one missing bolt was insignificant.

• During the area walkbys, the teams noted cases where conduit exiting top of MCCs were in proximity to overhead rigidly supported cable trays. Examples areas include the DG 2A and 2B Board Rooms. Simple conservative equations were used to estimate deflection, and in all cases it was confirmed that the clearance was adequate for the component design basis earthquake deflections.

" During the area walkbys, the teams noted isolated instances of not full thread engagement at bolted connection and misaligned unistrut channel nut connection. Each instance was reviewed and discussed thoroughly, and considered acceptable based on its as-installed configuration.

• During the area walkbys, the teams noted a variety of temporary equipment and installations such as scaffoldings, ladders, tools and tool boxes. In all cases, conditions were assessed and determined to be acceptable as-is.

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 SQN2 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 Sections 6.2 and 6.3 of the SQN2 Seismic Response Report.

Comments regarding the individual potential adverse seismic conditions for SQN2 include the following:

Potentially Adverse Seismic Condition 1 addresses a radiation protection cabinet that was marginally restrained in the Auxiliary Building Surge Tank B area at El. 734'. The cabinet was restrained on one of the two eye hook locations and in the current configuration it did not present a credible seismic interaction hazard to nearby safety related equipment. The walkdown team conservatively noted this as a potential adverse seismic condition and entered it into the CAP, and subsequently the cabinet was adequately restrained.

• Potentially Adverse Seismic Condition 2 addresses a temporary ventilation fan in the 480V Board Room 2A, in the vicinity of motor control center 2-BDC-201-GM-A. The floor fan was secured with chain and did not appear to be a credible interaction hazard given the position of the fan and the distance to the MCC cabinet. The walkdown team conservatively noted this as a potential adverse seismic condition and entered it into the CAP, and subsequently the fan was removed.

" Potentially Adverse Seismic Condition 3 addresses a crack noted at the top of a block wall next to the angle restraint that is common to the 125V Vital Battery Room IV and the 480V Board Room 2B. Bounding analyses, in consideration of the steel reinforcing in the wall, were performed to demonstrate that the as-found condition had sufficient margin to withstand design basis seismic loading. The walkdown team conservatively noted this as a potential adverse seismic condition and entered it into the CAP. Further engineering evaluation determined that the condition is acceptable.

• Potentially Adverse Seismic Condition 4 addresses unrestrained 55-gallon drums in the vicinity of safety-related instrument racks in the walkbys in the RHR, AFW and SI pump areas. In all cases, toppling or sliding of the drums would not compromise the safety function of instrument racks. The unrestrained drums however do not comply with applicable TVA procedures for restraint of temporary items. The walkdown team noted these cases as a potential adverse seismic condition. A CAP entry was submitted to address this issue, and the temporary equipment (drums) were removed from the areas.

• Potentially Adverse Seismic Condition 5 addresses a sink cabinet in the 125V Battery Room III that was not anchored in the same manner as the other battery rooms. Given its location with respect to the safety related equipment in the room, it was judged that the sink does not pose a seismic interaction and spray concern. The walkdown team noted this as a potential adverse seismic condition and entered it into the CAP.

Subsequently, the design calculation for the current configuration was retrieved, which indicates that the unrestrained cabinet is not a seismic concern nor spray hazard and is acceptable as-is.

Potentially Adverse Seismic Condition 6 addresses a missing bolt on a duct support above the Control Rod Drive Generator 2B (2-GEND-085-DH/3B) in the CRDM Room.

The duct and support configuration is judged to be robust and rugged and in the current configuration it did not present a credible seismic falling interaction hazard to nearby safety related equipment. The walkdown team noted this as a potential adverse seismic condition and entered it into the CAP. Further engineering evaluation determined that the condition is acceptable.

Potentially Adverse Seismic Condition 7 addresses a temporary scaffold near Unit 2 6.9kV Shutdown Board 2B-2 (2-BDB-202-CP). The walkdown team observed the scaffolding to be anchored only at one location at the top, noted the non-conforming scaffold as a potential adverse seismic condition, and entered it into the CAP.

Subsequently, the scaffolding was observed to be adequately restrained on its upper corner to a permanent plant feature. The temporary scaffold is found to be in compliance with TVA procedures.

NTTF 2.3/SQN-02 November 12, 2012 Page 7 of 7 Potentially Adverse Seismic Condition 8 addresses an unanchored cabinet with broken latch on the cabinet door for flammable materials during the area walkby of the ERCW Pump Room 2A-A. Given the location of the cabinet, it does not represent a direct seismic interaction source for any safety related equipment. The walkdown team conservatively noted this as a potential adverse seismic condition and entered it into the CAP, and subsequently the door lock was repaired to provide positive enclosure of the flammable materials within the cabinet.

• Potentially Adyerse Seismic Condition 9 addresses a nut and bolt not fully engaged on a fire protection pipe hanger in the vicinity of the Electrical Board Room Chillers. The walkdown team was concerned that the nut could loosen and become free during a seismic event. This is not considered to be a credible failure mode, and further evaluations indicated that the pipe hanger was able to perform its intended function.

The walkdown team conservatively noted this as a potential adverse seismic condition and entered it into the CAP.

• Potentially Adverse Seismic Condition 10 addresses a missing bolt attaching the axial fan of the Control Rod Drive Cooling Unit 2-AHU-030-0088 to its skid framework. The as-found configuration is stable and has sufficient margin to withstand design basis seismic loading -- 5 out of 6 bolts are sufficient to resist seismic demand shear loads; the flanged attachment of the fan to the AHU resists overturning moment. 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 SQN2 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.

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 sufficiently rigorous seismic-related construction and maintenance procedures that TVA has in place at SQN2. The walkdown demonstrates that the current plant configuration is in compliance with the current seismic licensing basis. Furthermore, the walkdown demonstrates that that TVA has maintained or improved the seismic IPEEE HCLPF capacity of the plant.
