41 iii Executive Summary The purpose of this report is to provide information as requested by the Nuclear Regulatory Commission (NRC) in its March 12, 2012 letter issued to all power reactor licensees and holders of construction permits in active or deferred status. (Ref. 12) In particular, this report provides information requested to address Enclosure 3, Recommendation 2.3: Seismic, of the March 12, 2012 letter. (Ref. 12)The 50.54(f) letter requires, in part, all U.S. nuclear power plants to perform seismic walkdowns to verify the current plant configuration is within the current seismic licensing basis and identify and address degraded, non-conforming or unanalyzed conditions found. This report documents the seismic walkdowns performed at Turkey Point Unit 3 in response, in part, to the 50.54(f) letter issued by the NRC.The Nuclear Energy Institute (NEI), supported by industry personnel, cooperated with the NRC to prepare guidance for conducting seismic walkdowns as required in the 50.54(f) letter, Enclosure 3, Recommendation 2.3: Seismic. (Ref.12).
The guidelines and procedures prepared by NEI and endorsed by the NRC were published through the Electric Power Research Institute (EPRI) as EPRI Technical Report 1025286, Seismic Walkdown Guidance for Resolution of Fukushima Near-Term Task Force Recommendation 2.3: Seismic, dated June 2012; henceforth, referred to as the "EPRI guidance document." (Ref. 1) Turkey Point has utilized this NRC endorsed guidance as the basis for the seismic walkdowns and this report. (Ref. 1)The EPRI guidance document was used to perform the engineering walkdowns and evaluations described in this report. In accordance with the EPRI guidance document, the following topics are addressed in the subsequent sections of this report." Seismic Licensing Basis* Personnel Qualifications
* Selection of Systems, Structures, and Components (SSC)* Seismic Walkdowns and Area Walk-Bys* Seismic Licensing Basis Evaluations" IPEEE Vulnerabilities Resolution Report" Peer Review Seismic Licensing Basis The safe shutdown earthquake for the Turkey Point site is 0.1 5g horizontal ground acceleration and 0.10 g vertical ground acceleration. (Ref. 2, Section 2)iv Personnel Qualifications The walkdown team consisted of experienced site personnel with Civil/Structural or Mechanical Engineering, Operations and PRA backgrounds.
Tile site personnel were supplemented by two vendors with significant experience in the area of seismic design and the performance of seismic walkdowns.
The personnel who performed the key activities required to fulfill the objectives and requirements of the 50.54(f) letter are qualified and trained as required in the EPRI guidance document (Ref. 1).Selection of SSCs One hundred (100) components were selected for the walkdown effort, including spent fuel pool items. These components were selected using the process described in detail in the EPRI guidance document, Section 3: Selection of SSCs. (Ref. 1)Seismic Walkdowns and Area Walk-Bys Section 5, Appendix C, and Appendix D of this report documents the equipment Seismic Walkdowns and the Area Walk-Bys.
The online seismic walkdowns for Turkey Point Unit 3 were performed September 10-14, 2012. The walkdown team consisted of two 2-person Seismic Walkdown Engineer (SWE) teams.The seismic walkdown team inspected 90 of the 100 components on the seismic walkdown equipment list (comprised of SWEL 1 and SWEL 2). Ten components were inaccessible and future walkdowns are planned for these items. Follow-up inspections are also to be performed on electrical panels that could not be opened at the time of the initial walkdown.Equipment Seismic Walkdowns included anchorage inspections and checks to verify as-found anchorages are consistent with design documents.
The walkdown found cases where the as-found anchorage was not consistent with the design document.
In other cases the document identifying anchorage design could not be identified.
Instances of anchor corrosion were cited, but the extent of corrosion is not a seismic capacity concern at this time. Except for the item E16B air handling unit (AH U), no concerns with overall anchorage strength were identified.
The E16B AHU was found to be lacking positive base anchorage.
The operability of the unit was addressed and the unit was found to be operable.Potential seismic interaction concerns were identified but none of the issues were considered to be hazards that rendered equipment inoperable.
Other equipment interaction issues are related to clearances between equipment and adjacent items and improper seismic housekeeping.
Loose or missing hardware, such as loose thumbscrews or latches, were found and cited under "Other" potentially adverse conditions.
Area Walk-Bys identified potentially adverse conditions -relate to improper seismic housekeeping.
Potential seismic interaction concerns were also identified but none of the issues were considered to be significant immediate hazards. In some cases potential relay chatter due to bumping of equipment is cited. Potential relay chatter issue is undesirable but the overall plant hazard related to relay chatter is typically low.For the Turkey Point USI A-46 evaluation (Reference 9), relay chatter was dismissed as a concern. One potential seismically-induced spray hazard was cited as requiring evaluation.-
v Seismic Licensing Basis Evaluations Conditions identified during the walkdowns were documented on the Seismic Walkdown Checklists (SWCs) and the Area Walkdown Checklists (AWCs), and entered into the CAP. For those conditions that operability or functionality could not be screened as acceptable, evaluations were initiated to demonstrate that the current licensing basis was met. Tables 5-2 and 5-3 in the report provide a summary of the conditions and the actions taken.IPEEE Vulnerabilities In lieu of a full IPEEE seismic analysis, FPL opted to submit a "scaled back" program to resolve USI A-46 and Generic Letter 87-02 as allowed by the NRC in a letter dated November 4, 1998 (Ref. 13) issued for the review of Turkey Point IPEEE evaluations.
The final results of this scaled back program for the A-46 program were submitted in a letter to the NRC, L-93-155, "Final Report of Plant Specific Seismic Adequacy Evaluation of Turkey Point Units 3 and 4 to Resolved USI A-46 and GL 87-02" (Ref. 14). The components selected for this analysis were also included in the SWEL in order to verify no outlier issues persisted.
Peer Reviews The Peer Review of the walkdowns consisted of two teams made up of Operations and PRA representatives and engineers with knowledge and experience in seismic inspections and assessments.
The engineers made up the SWE teams, but also served to peer review each other's work. The Operations and PRA representatives also participated in some of the walkdowns for logistical support as well as peer review.Appendix F of this report contains a summary of the Peer Review. The Peer Review determined that the objectives and requirements of the 50.54(f) letter are met. Further, it was concluded by the peer reviews that the efforts completed and documented within this report are in accordance with the EPRI guidance document.Summary In summary, seismic walkdowns have been completed at Turkey Point Unit 3 in accordance with the NRC endorsed walkdown methodology.
All potentially degraded, nonconforming, or unanalyzed conditions identified as a result of the seismic walkdowns have been entered into the corrective action program. None of the conditions found resulted in loss of operability or functionality of any structures, systems or components.
Follow-on activities required to complete the efforts to address Enclosure 3 of the 50.54(f) letter include inspection of items deferred due to inaccessibility along with supplemental inspections of electrical cabinets.
Area Walk-Bys will be complete, as required, during these follow-on activities.
vi I Introduction
 
==1.1 BACKGROUND==
 
In response to Near-Term Task Force (NTTF) Recommendation 2.3, the Nuclear Regulatory Commission (NRC) issued a 10CFR50.54(f) letter on March 12, 2012 requesting that all licensees perform seismic walkdowns to identify and address plant degraded, non-conforming, or unanalyzed conditions, with respect to the current seismic licensing basis. The Nuclear Energy Institute (NEI), through the Electric Power Research Institute (EPRI), prepared industry guidance to assist licensees in responding to this NRC request. The industry guidance document, EPRI Technical Report 1025286, Seismic Walkdown Guidance for Resolution of Fukushima Near-Term Task Force Recommendation 2.3: Seismic, dated June 2012 (Reference 1), was endorsed by the NRC on May 31, 2012. NextEra/Florida Power & Light Company (FPL) has committed to using this guidance as the basis for completing the walkdown effort.1.2 PLANT OVERVIEW The Turkey Point (PTN) site is located on the west shore of Biscayne Bay in Dade County, Florida. The site is 25 miles south of Miami and eight miles east of Florida City.The site contains two fossil units (Unit 1 and 2), two nuclear units (Units 3 and 4), and one combined cycle gas-powered unit (Unit 5). The plant's nuclear steam supply system (NSSS). was designed by Westinghouse Electric Corporation.
The Containment structure and balance of plant was designed by Bechtel Corporation.
The general description of the plant given above is based on the information in the UFSAR (Reference 2).1.3 APPROACH The EPRI Seismic Walkdown Guidance (Reference
: 1) was used for the seismic walkdowns and evaluations described in this report. In accordance with Reference 1, the following topics are addressed in the subsequent sections of this report: " Seismic Licensing Basis* Personnel Qualifications" Selection of SSCs" Seismic Walkdowns and Area Walk-Bys" Licensing Basis Evaluations
* IPEEE Vulnerabilities Resolution Report" Peer Review 1 2 Seismic Licensing Basis 2.1 SITE SEISMICITY Site seismicity is discussed in UFSAR (Reference
: 2) Section 2. On the basis of historical or statistical seismic activity, Turkey Point is located in a seismically inactive area, far from any recorded damaging shocks. Even though several of the larger historical earthquakes may have been felt in southern Florida, the amount of ground motion caused by them was not great enough to cause damage to any moderately well-built structure.
Predicated on history, building codes, geologic conditions, and earthquake probability, the design earthquake was conservatively established as 0.05 g horizontal ground acceleration.
The nuclear units have also been evaluated for a 0.15 g ground acceleration to assure no loss of function of the vital systems and structures.
Vertical acceleration is taken as 2/3 of the horizontal value and is considered to act concurrently.
 
===2.2 SEISMIC===
DESIGN BASIS The seismic design was based on the acceleration ground response spectrum curves shown in UFSAR Figures 5A-1 and 5A-2. The curves were derived from the "Housner Spectrum" normalized to 0.05g for the design earthquake and 0.15g for the maximum earthquake.
The UFSAR commitment for a maximum earthquake was determined at a time when probabilistic definition of seismic input had not been developed with any degree of consistency or confidence.
Therefore, the 0.15g PGA was conservatively estimated based on very limited data available at the time.The original design basis commits Turkey Point to the 1967 proposed version of General Design Criterion (GDC) Number 2 that relates to earthquake natural phenomena as identified below and is as follows: "Those systems and components of reactor facilities which are essential to the prevention or to the mitigation of the consequences of nuclear accidents which could cause undue risk to the health and safety of the public shall be designed, fabricated, and erected to performance standards that will enable such systems and components to withstand, without undue risk to the health and safety of the public the forces that might reasonably be imposed by the occurrence of an extraordinary natural phenomenon such as earthquake, tornado, flooding condition, high wind or heavy ice.The design bases so established shall reflect: (a) appropriate consideration of the most severe of these natural phenomena that have been officially recorded for the site and the surrounding area and (b) an appropriate margin for withstanding forces greater than those recorded to reflect uncertainties about the historical data and their suitability as a basis for design." 2 AEC Publication TID-7024 (Reference
: 4) was used as the basic design guide for earthquake analysis.
Floor response spectra were developed from the ground spectra for the Containment Buildings and Control Building to evaluate structures, systems, and components at the various elevations of those structures.
Earthquake forces were applied simultaneously in the vertical and any horizontal direction.
The vertical component of acceleration at any level was taken as two-thirds of the horizontal ground acceleration.
The damping factors for various types of construction are listed in Reference 2, Appendix 5A.For concrete structures and components, the basic code for determining the section strengths for original design was ACI 318-63 (Reference 5). For steel structures and components, the basic code for determining the section strengths was the AISC Steel Construction Manual, 6th Edition (Reference 6). Later codes were used for plant upgrades.
Design requirement for equipment varied by equipment type. The mechanical and electrical equipment were purchased under specifications that include a description of the seismic design criteria for the plant. Motor control centers and load centers were shake table tested to demonstrate no-loss-of-function capacity under the maximum hypothetical earthquake.
The Turkey Point units were within the scope of NRC unresolved safety issue (USI) A-46 (Reference 7), which required a re-evaluation of safety-related mechanical and electrical equipment.
At about the same time the NRC asked all operating power plants to undertake an investigation of design capability to extreme external events (Reference 8).Turkey Point resolved these issues as discussed in the next section. Resolution included implementation of seismic design improvements.
2.3 USI A-46 AND SEISMIC IPEEE Generic Letter 87-02, "Verification of Seismic Adequacy of Mechanical and Electrical Equipment in Operating Reactors, Unresolved Safety Issue (USI) A-46" (Reference 7)addressed seismic adequacy of equipment at older nuclear plants. Turkey Point Units 3 and 4 were within the scope of USI A-46.The evaluation of Turkey Point for resolution of USI A-46 is reported in Reference 9.FPL developed and implemented a plant specific program to satisfy requirements of USI A-46 as agreed between FPL and the USNRC. The program consisted of developing a walkdown procedure that concentrated on anchorage concerns of USI A-46, the seismic spatial interaction concerns of USI A-17 and the design concerns for large tanks in USI A-40. The program was developed by FPL to be appropriate and cost effective for addressing GL87-02 concerns at its low seismic sites. The basic requirement for the walkdown was that the equipment be able to withstand the design basis SSE at the plant and still provide its safe shutdown function.
The procedure used relied on the judgment of an expert team to meet the basic requirement.
A success path of equipment using safety and non-safety equipment was selected for achieving hot shutdown of the plant within a period of 8 hours.An assessment of the anchorage adequacy was performed on each equipment item included on the safe shutdown list. This included an assessment of the seismic demand on the equipment anchorage (forces and stresses on the anchorage), the seismic capacity of the anchorage components (attachment of the equipment to the anchorage, 3 the anchorage itself, and the development of the anchorage to the foundation), and whether the capacity of the weak link of the anchorage system exceeded the demand.A seismic spatial interaction assessment was performed on each equipment item included on the safe shutdown list. The following seismic spatial interaction issues were evaluated:
: 1) heavy objects falling (sometimes referred to as II over .I interactions), 2)heavy objects sliding, swinging, vibrating or tipping (proximity interactions) and 3)inadequate flexibility of lines to accommodate seismic-induced relative movements between utility support points. An assessment was made as to whether possible interactions existed, and if it did, could the interaction preclude the equipment item from performing a safe shutdown function.
Those interactions identified as possibly precluding the equipment item's safe shutdown function were identified as outliers.The walkdown resulted in the identification of outlier equipment items with the majority of the outliers being lack of anchorage for electrical cabinets which were not previously required to be anchored.
FPL addressed all outlier issues listed and the actions taken are listed in Reference 9 Table 5.0. In many cases, FPL engineering generated Plant Change/Modification (PC/M) Packages which provided for physical modification to plant equipment resulting in additional seismic "hardening" of the equipment.
Generic Letter 88-20, Supplement 4, "Individual Plant Examination of External Events (IPEEE) for Severe Accident Vulnerabilities" (Reference
: 8) addressed plant-specific vulnerabilities to severe accidents.
For implementation of the IPEEE, Turkey Point was classified as a "reduced scope" plant per NUREG-1407 (Reference1O).
As such, the review level earthquake was equal to the site SSE and completion of the USI A-46 assessment largely satisfied the seismic IPEEE requirements.
FPL informed the NRC that the plant specific program developed for USI A-46 would be used to resolve GL 88-20 Supplement 4 at Turkey Point (see Reference 11).4 3 Personnel Qualifications

SELECTION PERSONNEL The SWEL development was performed by the Peer Review Team Lead member of the PRA Group. The SWEL was then independently reviewed by another member of the PRA Group, by Operations, and finally by Peer Reviewers from Engineering.
 
===3.4 SEISMIC===
WALKDOWN ENGINEERS The seismic walkdowns were performed by four seismic walkdown engineers (SWEs)grouped into two seismic walkdown teams (SW-Ts).The lead SWEs are engineers from Stevenson and Associates (S&A). S&A is recognized internationally as a leading seismic consultant to the nuclear industry and as a regular contributor to the advancement of earthquake engineering knowledge through funded research projects.
The professional staff has expertise and capabilities in earthquake enginee.ing, -structural dynamics, and structural design. S&A has performed seismic evaluatiblis of US nuclear power plants, using either Seismic Probabilistic Risk Assessment (PRA) or Seismic Margin Assessment, to address US Nuclear Regulatory Commission (NRC) Individual Plant Evaluation for External Events (IPEEE) for over 35 US and European plants.3.5 LICENSING BASIS REVIEWERS The Licensing Basis Reviewers consisted of the four seismic walkdown engineers.
The FPL engineers had the lead in licensing basis determinations, with support from the S&A engineers.
 
===3.6 IPEEE===
REVIEWERS IPEEE reviewers were engineers familiar with implementation of IPEEE at the Turkey Point site. The IPEEE Reviewers also participated in the SWEL preparation and seismic walkdowns.
3.7 PEER REVIEW TEAM The Peer Review Team is listed, along with their roles and qualifications, in the Peer Review Report included in Appendix F.3.8 ADDITIONAL PERSONNEL Operations personnel also provided support to the walkdown by reviewing the list of components for accessibility and accompanying the SWTs to open cabinet doors for accessibility to anchorage.
6 4 Selection of SSCs The Seismic Walkdown Equipment List is documented in the SWEL Selection Report, provided in Appendix B. This report describes how the SWEL was developed to meet the requirements of EPRI Seismic Walkdown Guidance (Reference 1). The summary of the Seismic Walkdown Equipment List is included in Appendix C under Table C-1 Summary of Seismic Walkdown Checklists.
The final SWEL (both SWEL 01 & SWEL 02)which details all of the component attributes used in the screening process, as well as the Master Component List, are on-file.7 5 Seismic Walkdowns and Area Walk-Bys 5.1 OVERVIEW The Seismic Walkdowns and Area Walk-Bys were conducted by 2-person teams of trained Seismic Walkdown Engineers, in accordance with the EPRI Seismic Walkdown Guidance (Reference 1). The walkdowns occurred on September 10-14, 2012.Components in the Containment building were inaccessible and will be inspected during the next refueling outage, currently scheduled for early 2014. The Seismic Walkdowns and Area Walk-Bys are discussed in more detail in the following sections.5.2 SEISMIC WALKDOWNS The Seismic Walkdowns focused on the seismic adequacy of the items on the SWEL as provided in Appendix B of this report. The Seismic Walkdowns also evaluated the potential for nearby SSCs to cause adverse seismic interactions with the SWEL items.The Seismic Walkdowns focused on the following adverse seismic conditions associated with the subject item of equipment: " Adverse anchorage conditions" Adverse seismic spatial interactions" Other adverse seismic conditions The results of the Seismic Walkdowns have been documented on the Seismic Walkdown Checklist (SWC) provided in the EPRI guidance document, Appendix C.Seismic Walkdowns were performed for 90 of the 100 items identified on the Turkey Point Unit 3 SWEL. The remaining items will be inspected in the refueling outage as previously noted. The associated SWCs are provided in Appendix C of this report.Additionally, photos have been included with most SWCs to provide a visual record of the item along with any comments noted on the SWC. These photos are not included to limit the size of this report but are on file. Drawings and other plant records are cited in some of the SWCs, but are not included with the SWCs because they are readily retrievable documents through the station's document management system.Inspection for certain items could not be completed due to access restrictions.
Appendix E of this report identifies the inaccessible equipment along with the plan for future Seismic Walkdowns.
The following subsections describe the approach followed by the SWEs to identify potentially adverse anchorage conditions, adverse seismic interactions, and other adverse seismic conditions during the Seismic Walkdowns.

====5.2.1 Adverse====
Anchorage Conditions
* Guidance for identifying anchorage that could be degraded, non-conforming, or unanalyzed relied on visual inspections of the anchorage and verification of anchorage configuration.
Details for these two types of evaluations are provided in the following two subsections.
The evaluation of potentially adverse anchorage conditions described in this subsection applies to the anchorage connections that attach the identified item of equipment to the civil structure on which it is mounted. For example, the welded connections that secure the base of a Motor Control Center (MCC) to the steel embedment in the concrete floor would be evaluated in this subsection.
Evaluation of the connections that secure components within the MCC is covered later in the subsection "Other Adverse Seismic Conditions." Visual Inspections The purpose of the visual inspections was to identify whether any of the following potentially adverse anchorage conditions were present:* Bent, broken, missing, or loose hardware" Corrosion that is more than mild surface oxidation" Visible cracks in the concrete near the anchors* Other potentially adverse seismic conditions Based on the results of the visual inspection, the SWEs judged whether the anchorage was potentially degraded, non-conforming, or unanalyzed.
The results of the visual inspection were documented on the SWC, as appropriate.
If there was clearly no evidence of degraded, nonconforming, or unanalyzed conditions, then it was indicated on the checklist and a licensing basis evaluation was not necessary.
However, if it was not possible to judge whether the anchorage is degraded, nonconforming, or unanalyzed, then the condition was entered into the Corrective Action Program as a potentially adverse seismic condition for further evaluation.
Additionally, any significant comments are noted on the SWCs. Drawings and other plant design documents are cited in some of the SWCs, but they are not included with the SWCs because they are readily available in the plant's electronic document management system.5.2.2 Anchorage Configuration Confirmation As required by the EPRI Seismic Walkdown Guidance (Reference 1, page 4-3), at least 50% of the items were confirmed to be anchored consistent with design drawings.
Line-mounted equipment (e.g., valves mounted on pipelines without separate anchorage) was not evaluated for anchorage adequacy and was not counted in establishing the 50%sample size.Examples of documentation that was considered to verify that the anchorage installation configurations are consistent with the plant documentation include! the following:

N: component which had anchorage but was not chosen for anchorage configuration confirmation.

An inspection was performed in the area adjacent to and surrounding the SWEL item to identify any seismic interaction conditions that could adversely affect the capability of that SWEL item to perform its intended safety-related functions.
The three types of seismic spatial interaction effects that were considered are: o Proximity a Failure and falling of SSCs (Seismic II over I)* Flexibility of attached lines and cables Detailed guidance for evaluating each of these types of seismic spatial interactions is described in the EPRI guidance document, Appendix D: Seismic Spatial Interaction.
The Seismic Walkdown Engineers exercised their judgment to identify seismic interaction hazards. Section 5.2.5 provides a summary of issues identified during the Seismic Walkdowns.
 
====5.2.4 Other====
Adverse Seismic Conditions In addition to adverse anchorage conditions and adverse seismic; interactions, described* above, other potentially adverse seismic conditions that could challenge the seismic adequacy of a SWEL item were evaluated.
These inspections were mostly associated 10 with in-cabinet inspections of selected electrical equipment.
Examples of the types of conditions that could pose potentially adverse seismic conditions include the following:
* Degraded conditions
* Loose or missing fasteners that secure internal or external components to equipment* Large, heavy components mounted on a cabinet that are not typically included by the original equipment manufacturer
* Cabinet doors or panels that are not latched or fastened Any identified other adverse seismic conditions are documented on the items' SWC and Table 5-2, as applicable.
 
====5.2.5 Issues====
Identification during Seismic Walkdowns Table 5-2 provides a summary of issues identified during the equipment Seismic Walkdowns and recorded on SWCs. The tracking of issue resolution is identified in the table. Items are grouped based on the walkdown issue cited: " Anchorage issues* Seismic interaction issues" Other conditions
* Anchorage documentation not available* Anchorage inspection could not be fully completed The majority of potentially adverse anchorage conditions found are related to documentation of as-found anchorage.
In those cases either the as-found anchorage was not consistent with the available document, or the document identifying the anchorage design could not be identified.
Except for the item E16B air handling unit (AHU), no concerns with overall anchorage strength were identified.
There was one instance where anchor corrosion was cited, but the extent of corrosion is minor at this time. The E16B AHU was found to be lacking positive base anchorage.
Low seismic ruggedness of attached piping was also cited as a concern. The operability of the unit was addressed and the unit was found to be operable.Potential seismic interaction concerns were identified but none of the issues were considered to be significant hazards but will be addressed to reduce risk. Most equipment interaction issues are related to clearances between equipment and adjacent items and improper seismic housekeeping.
Under good seismic housekeeping practice, transient and moveable items (e.g., ladders) should be restrained or stowed such that they will not slide into or fall against important plant equipment.
Items considered minor maintenance issues, such as loose or missing thumbscrews or latches, were found and cited under "Other" potentially adverse conditions.
In addition, these items were entered into the Corrective Action Program under separate Action Requests (ARs). None of these items affect component anchorage.
For items requiring anchorage verification, the SWC anchorage verification checklist item was set to "Unknown" if an anchorage design document could not be found.Notwithstanding, the configuration was assessed to ensure that there was no immediate 11 operability concern. Also, anchorage checklist items were set to "Unknown" when the walkdown team could not see all anchors., For example, some anchors (relatively few)of control cabinets were covered by wiring. A comment is included on the corresponding SWC to explain that certain anchors out of the group could not be seen. Again, the configuration was assessed to establish that there was no immediate operability concern.12 Table 5-2: Table of Actions Resulting from Seismic Walkdown Inspection Entered Equipment ID Potentially Adverse Seismic Condition Resolution into CAP Current Status Anchorage issues As-found anchorage determined to be 3B EDG FAN Anchorage does not match pattern adequate given the size and geometry ASSEMBLIES shown on drawing 5610-C-379 Sh. 1. of fan assemblies.

30 5.3 AREA WALK-BYS The purpose of the Area Walk-Bys is to identify potentially adverse seismic conditions associated with other SSCs located in the vicinity of the SWEL items. Vicinity is generally defined as the room containing the SWEL item. If the room is very large (e.g., Turbine Hall), then the vicinity is identified based on judgment, e.g., on the order of about 35 feet from the SWEL item. This vicinity is described on the Area Walk-By Checklist (AWC), shown in Appendix D of this report. A total of 45 AWCs were completed for Turkey Point Unit 3. Note that additional AWCs will be completed, as required, when deferred inspections are completed.
The key examination factors that were considered during Area Walk-Bys include the following:
* Anchorage conditions (if visible without opening equipment)
* Significantly degraded equipment in the area" A visual assessment (from the floor) of cable/conduit raceways and HVAC ducting (e.g., condition of supports or fill conditions of cable trays)" Potentially adverse seismic interactions including those that could cause flooding, spray, and fires in the area* Other housekeeping items that could cause adverse seismic interaction (including temporary installations and equipment storage)* Scaffold construction was inspected for adequate bracing and anchorage" Hazards from temporary equipment were evaluated and overall seismic housekeeping was evaluated The Area Walk-Bys are intended to identify adverse seismic conditions that are readily identified by visual inspection, without necessarily stopping to open cabinets or taking an extended look. If a potentially adverse seismic condition was identified during the Area Walk-By, then additional time was taken, as necessary, to evaluate adequately whether there Was an adverse condition and to document any findings.The results of the Area Walk-Bys are documented on the AWCs included:
in Appendix D of this report. A separate AWC was filled out for each area inspected.
A single AWC was completed for areas where more than one SWEL item was located.Additional details for evaluating the potential for adverse seismic interactions that could cause flooding, spray, or fire in the area are provided in the following two subsections.
Seismically-Induced Floodinc/Spray Interactions Seismically-induced flooding/spray interactions are the effect of possible ruptures of vessels or piping systems that could spray, flood or cascade water into the area where SWEL items are located. This type of seismic interaction was considered during the IPEEE program. Those prior evaluations were considered, as applicable, as information for the Area Walk-Bys.One area of particular concern to the industry is threaded fire protection piping with long unsupported spans. If adequate seismic supports are present or there are isolation valves near the tanks or charging sources, flooding may not be a concern. Numerous 31 failures have been observed in past earthquakes resulting from sprinkler head impact.Less frequent but commonly observed failures have occurred due to flexible headers and stiff branch pipes, non-ductile mechanical couplings, seismic anchormotion and failed supports.Examples where seismically-induced flooding/spray interactions could occur include the following:
* Fire protection piping with inadequate clearance around fusible-link sprinkler heads* Non-ductile mechanical and threaded piping couplings can fail and lead to flooding or spray of equipment" Long, unsupported spans of threaded fire protection piping* Flexible headers with stiffly supported branch lines" Non-Seismic Category I tanks The SWEs exercised their judgment to identify only those seismically-induced interactions that could lead to flooding or spray. Fire protection piping at Turkey Point Unit 3 was found to be sufficiently restrained in areas where SC-I equipment items are located and no concerns were identified with fire protection piping.One potential seismic-induced spray interaction was identified at Turkey Point Unit 3 and included as an issue to be resolved.
This is related to the E16B AHU discussed in Section 5.2.Seismically-Induced Fire Interactions Seismically-induced fire interactions can occur when equipment or systems containing hazardous/flammable material fail or rupture. Examples where seismically-induced fire interactions could occur include the following: , Hazardous/flammable material stored in inadequately anchored drums, inadequately anchored shelves, or unlocked cabinets* Natural gas lines and their attachment to equipment or buildings* Bottles containing acetylene or similar flammable chemicals* Hydrogen lines and bottles Another example where seismically-induced fire interaction could occur is when there is relative motion between a high voltage item of equipment (e.g., 4160 volt transformer) and an adjacent support structure when they have different foundations.
This relative motion can cause high voltage busbars,ý which pass between the two, to short out against the grounded bus duct surrounding the busbars and cause a fire.The Seismic Walkdown Engineers exercised their judgment to identify only those seismically-induced interactions that could lead to fires.One potential seismic-fire interaction was identified at Turkey Point Unit 3 and included as an issue to be resolved.
Valve POV-3-4883 is located in the vicinity of a main station transformer and the transformer is considered a potential fire source.32 Area Walk-By Results Table 5-3 provides a summary of issues identified during the Area Walkdowns and recorded on AWCs. The tracking of issue resolution is identified in the table. Items are grouped based on the walkdown issue cited: " Seismic housekeeping issues* Other seismic interaction issues" Other conditions The majority of potentially adverse conditions found are related to seismic housekeeping.
Potential seismic interaction concerns were identified but none of the issues were considered to be significant immediate hazards. III some cases potential relay chatter due to bumping of equipment is cited. Potential relay chatter issue is undesirable but the overall plant hazard related to relay chatter is typically low. For the Turkey Point USI A-46 evaluation (Reference 9), relay chatter was dismissed based on the low probability along with being able to manage the effects if they were to occur. As stated, one potential seismic-induced spray hazard and one potential seismic-induced fire hazard are cited as items requiring evaluation.

For those conditions that required a seismic licensing basis evaluation, an operability screening has been performed and an evaluation will be performed to provide the final resolution to be documented within the corresponding condition reports. Table 5-2 and 5-3 of this report provide the status of the subject evaluations as applicable.
39 IPEEE Vulnerabilities Resolution Report As discussed in previously Section 2.3, for implementation of the IPEEE Turkey Point was classified as a "reduced scope" plant per NUREG-1407 (Ref. 10). As such, the review level earthquake was equal to the site SSE and completion of the USI A-46 assessment largely satisfied the seismic IPEEE requirements.
In lieu of a full IPEEE seismic analysis, FPL opted to submit a "scaled back" program to resolve USI A-46 and Generic Letter 87-02 as allowed by the NRC in a letter dated November 4, 1998 (Ref. 13) issued for the review of Turkey Point IPEEE evaluations.
The final results of this scaled back program for the A-46 program were submitted in a letter to the NRC, L-93-155, "Final Report of Plant Specific Seismic Adequacy Evaluation of Turkey Point Units 3 and 4 to Resolved USI A-46 and GL 87-02" (Ref. 14). The components selected for this analysis were also included in the SWEL in order to verify no outlier issues persisted.

Date Dafe Date Sh/I/ I l.Date B-1 1 Introduction This document contains the information used to develop the Seismic Walkdown Equipment List (SWEL) at Turkey Point (PTN) in accordance with EPRI Report 1025286, "Seismic Walkdown Guidance," dated June 2012 [1].The selection process was completed by applying separate screening criteria to develop SWELs 1 and 2. The documentation is laid out by first providing the screening criteria requirements, and then providing the implementation of how PTN applied that screening criteria.2 Process The general process focused first on building a Master Component List, with attributes to support the sample selection process (Sections 3 and 4). This list was obtained by generating a NAMS query of the entire PTN Equipment Database for all components along with data such as system code, component type, location, etc. Then the screening criteria below were applied to arrive at a final SWEL 1 and SWEL 2 comprised of about 92 items and 8 items, respectively.
The process also included identifying a set of plant locations around which the walkdown was organized (Section 5). The plant locations were also used to support the "walk-by" process to assess cable trays and ventilation ducts and the potential for seismic spatial interactions (Section 6).Finally, Section 6 identifies several evaluations that supported the identification of targets for the walkdown and the specific attributes that needed to be examined.Because the SWEL needs to address a number of attributes, the selection was performed and reviewed by a team that includes representatives from PRA, Operations, and Engineering.
This was done systematically by performing table-top virtual walkdowns and pre-walkdowns of each location to identify candidates for the SWEL as well as other issues (e.g., seismic-flood) that needed to be inspected by the walk-by.3 SWEL 1 Screening Criteria The final SWEL 1 is contained in the Microsoft Excel workbook, "U3 (U4) PTN Fukushima SWEL" [2], in the "SWEL 1" spreadsheet on file. Each iteration of the screening process described below is contained in the Microsoft Access database, "SWEL 1"[3]. These final SWEL (both SWEL 01 & SWEL 02), as well as the Master Component List, are available in. Excel format on file at Turkey Point.3.1 Screening Criteria 1 -Seismic Category I Requirement The scope of SSCs (Systems, Structures, and Components) in the plant ýare limited to those that are designed to Seismic Category (SC) I requirements.
This is done because only such items have a defined seismic licensing basis against which to evaluate the as-installed configuration.
B-2 Selecting these items is intended to comply with the request in the NRC 50.54(f) Letter, under the "Requested Actions" section, to "verify current plant configuration with the current license basis." Application Seismic Class 1 SSCs include over 20,000 items in the PTN equipment database.
A complete equipment list from the PTN equipment database was obtained via a NAMS query ran in June 2012. The Seismic Class 1 SSCs were queried from the report by choosing only those SSCs where the Seismic Class was designated with an I.3.2 Screening Criteria 2 -Equipment or Systems Requirement The scope of SSCs included selecting only those that do not regularly undergo inspections to confirm that their configuration continues to be consistent with the plant licensing basis.Cable/conduit raceways and HVAC ductwork were not included as "equipment" in the SWEL 1, and were instead left to be reviewed during area walk-bys of the spaces containing items on the SWEL 1. Also omitted were SC 1 structures, containment penetrations, and SC1 piping systems.Application The list of all SCI SSCs was further reduced by including only "active" components, removing all items classified as "design" or "non-equip".
 
===3.3 Screening===
 
Criteria 3 -Supports 5 Safety Functions Requirement The scope of SSCs to be included in SWEL 1, are those SSCs associated with maintaining the five safety functions.
These five safety functions include the four safe shutdown functions (reactor reactivity control, reactor coolant pressure control, reactor coolant inventory control, and decay heat removal, which includes the Ultimate Heat Sink), plus the containment functions.
Application Since the PRA risk model represents the five safety functions listed above, a list of all PRA component tags was compared to the remaining SSCs. Items not included in the PRA model were removed.3.4 Screening Criteria 4 -Sample Considerations Requirement It was expected that SWEL 1, taken as a whole, would include representative items from some of the variations within each of the following five attributes:
A variety of types of systems B-3 Major new and replacement equipment* A variety of types of equipment* A variety of environments
* Equipment enhanced due to vulnerabilities identified during the IPEEE program Application The seismic aspects of the PTN IPEEE were resolved by the use of the FPL site-specific Seismic Program associated with Unresolved Safety Issue (USI) A-46 [4]. The equipment analyzed in this program was used as a base and compared to the screening criteria above.The remaining components in the Master Component List were reordered according to system code, component type, and then location in order to obtain a broad sample. Operations personnel were consulted with to identify new or replaced equipment that were on the truncated Master Component List.4 SWEL 2 Screening Criteria SWEL 2 began with the same Master Component List as SWEL 1. An initial screening was done retaining only SSCs related to the Spent Fuel Pool system. Screening criteria 1, 2, and 3 for SWEL 2 were performed identically to that of screening criteria 1,2, and 4 for SWEL 1, respectively.
The final SWEL 2 is contained in the Microsoft Excel workbook, "U3 (U4) PTN Fukushima SWEL" [2], in the "SWEL 2" spreadsheet on file. Each iteration of the screening process is contained in the Access database, "SWEL 2" [5]. These Microsoft Excel Workbooks, as well as the Master Component List are available in Excel format on file at Turkey Point.4.1 Screening Criteria 4- Cause Rapid Drain-Down Requirement The EPRI guidance requires assessment of the potential for Spent Fuel Pool (SFP) rapid draindown, specifically the identification of SFP penetrations below about 10 feet above the top of the fuel assemblies.
Application There are only two penetrations in the SFP below this level. One is a lower suction valve (*-797), the other is the fuel transfer tube, used to move fuel from containment to the SFP. During normal operation, this tube is isolated by a blind flange on the containment side and a manual valve on the Fuel Storage Building side. Other components were included in this screening based on their importance in maintaining spent fuel pool inventory and cooling.B-4 5 Walk-By Table Each location will also be subject to a walk-by, an examination (in less detail) of the other PRA components, as well as an inspection for other seismic issues:* Several other passive component types: cable trays & ventilation ducts.* Seismic-induced fire. This includes all flammable materials in each location such as hydrogen lines, gas bottles (acetylene, hydrogen), natural gas lines, and hazardous/flammable material stored in the location.* Seismic-induced flood. This includes all flood/spray sources (tanks, piping) originating in each location, based on the Internal Flood PRA. Note, the flood sources of interest are only those originating in the location, not those coming from another location.
The potential for flood propagation will be addressed in the seismic/flood analysis.* Spatial interactions (2 / 1). This includes adverse physical interaction due to proximity, failing of other components or structures (e.g., cranes), and flexibility of attached lines and cables.The final Walk-By Table is contained in the Microsoft Excel workbook, "U3 PTN Fukushima SWEL" [21, in the "Walkby Table" spreadsheet as well as the Master Component List are available in Excel format at Turkey Point on file.6 Evaluations The following evaluations were performed prior to and during the walkdown to assess specific issues that may add to the walkdown scope or the inspection criteria.6.1 IPEEE or USI A-46 Vulnerabilities The seismic assessment performed for PTN USI A-46 was reviewed for any seismic vulnerability identified.
These issues were included in the SWEL table.6.2 Configuration Verification The EPRI guidance identifies two types of inspection for the walkdown: (a) visual inspection and (b) configuration verification.
Visual inspection is typically what is performed in a walkdown, looking for obvious degraded conditions in equipment anchorage.
However, configuration verification is a more involved inspection consistent with the existing plant documentation of the design basis. This is required in at least 50% of the SWEL items with anchorage.
Since 28 SWEL components are MOVs (Class 8) or AOVs (or similar Class 7 components) which do not have anchorage, this leaves 50% of 72, or at least 36 components to be included in the configuration verification.
For those components, the design basis was reviewed and the key attributes included in the walkdown forms to assist the inspection.
6.3 New Equipment B-5 The EPRI Guidance directs that the SWEL should include a "robust sampling of the major new or replacement equipment installed within the past 15 years (i.e., since the approximate completion of the seismic IPEEE evaluation)".
Based on discussion with Operations and Engineering, major new or replacement equipment was identified and noted as such in the SWEL spreadsheet.

The walkdown team allowed for changes to be made to the SWEL mid-walkdown.
Many components were changed from 'B' train to 'A' train as the former was the protected train, precluding the thorough inspection of some components.
Various items were also replaced or removed because they were common components already on the other unit's SWEL or the component was no longer installed in the plant.7 References

: 1. INTRODUCTION This report documents the peer review of the seismic walkdowns performed for Turkey Point Nuclear Station in September 2012, in support of the NRC Near Term Task Force (NTTF)Recommendation 2.3. This document describes the peer review team and process (Section 3), the peer review of the SWEL selection (Section 4), and the peer review of the seismic walkdown (Section 5).The peer review was performed consistent with Section 6 of the EPRI-TR-1 025286 (REF 1)guidance document and addresses the following specific activities:
* Review of the selection of components for the Seismic Walkdown Equipment List (Section 4)" Review of a sample of the checklists prepared for the Seismic Walkdowns
& Walk-Bys (Section 5.1)" Review of any licensing basis evaluations (Section 5.2)" Review of the decisions for entering the potentially adverse conditions in to the plant's Corrective Action Program (Section 5.2)* Review of the final submittal report (Section 6).2. BACKGROUND This peer review covers three portions of the seismic walkdown: (a) the preparation of the SWEL, (b) the actual walkdown, and (c) the final submittal report.The Seismic Walkdown Equipment List (SWEL) was prepared in July and August and finalized in September, based on revisions that occurred during the walkdowns.
Section 3 describes the process of peer reviewing the SWEL.The vast majority of the seismic walkdowns occurred September 11 through September
: 20. The peer review of the walkdowns occurred in the afternoons of those same dates. This portion of the peer review is documented in Section 4.Two entire areas -the containments
-were deferred for each unit for completion during each following respective outage. This allowed the walkdown to occur with less radiation exposure to the walkdown team.Four components could not be examined entirely with the bus powered: Essential 4KV switchgear Buses 3AB and 4AB, and the protected sequencers during walkdowns which were 3C23B and 4C23B. Consequently, the walkdowns for these components were postponed until the next scheduled outage when they. can be scheduled to be removed from service for maintenance.
These inspection deferrals are being tracked under the Corrective Action Program (CAP) by two separate Actions Requests, one for each unit.F-2
: 3. PEER REVIEW TEAM & PROCESS The Turkey Point (PTN) Peer Review Team consisted of individuals from PTN operations, civil engineering, licensing, and PRA as well as structural/seismic engineers from Stevenson
&Associates.
These individuals participated in phases of preparation, performance, and peer review of the seismic walkdowns.
This section documents the peer review process and how the Peer Review Team interacted with the Seismic Walkdown Engineering Teams.3.1 Peer Review Team The affiliation, role, and qualifications for each Peer Review Team member are summarized in the following table.Name Group Role

Restrepo served as the Peer Review Team Lead. In that role, he was responsible for coordinating the peer review and assembling this report. As described below, he also performed some additional roles as part of the walkdown team PR. He also had the lead in the SWEL preparation, so he was not part of that PR process. As such, the SWEL was independently reviewed by a PRA Engineer from PSL, a Senior License Operator from PTN and one of the Peer Reviewers from PTN. Finally, he did not participate as an active team member during the seismic walkdown process and did not perform any other work besides the one described above. Therefore, his roll as the lead pear reviewer is considered acceptable F-3 SWEL Preparation The SWEL was prepared by A. Restrepo, who is a PTN PRA engineer, with PTN Operations experience and familiarity with the PTN IPEEE Report and the PTN PRA model.The SWEL was reviewed by a team that included a PRA engineer (G. Tullidge), a licensing engineer (T. Satyan Sharma), a civil engineer (A. Figueroa), and an Operations representative (T. Jones). All of these individuals are familiar with the design and layout of the plant and plant documentation.
Seismic Walkdown The primary seismic walkdown was conducted with two teams, each with two qualified structural/seismic engineers.
The Peer Review of the walkdowns consisted of a Peer Review Team Lead with Operations and PRA knowledge, and structural/seismic engineers.
The structural/seismic engineers made up the SWE teams, but also served to peer review each other's work. The Peer Review Team Lead also participated in many of the walkdowns for logistical support as well as peer review. The ultimate judgments regarding licensing basis were made by qualified PTN structural engineers.

: 4. PEER REVIEW -SELECTION OF COMPONENTS FOR SWEL The purpose of this section is to describe the process to perform the peer review of the selected components that were included in the Seismic Walkdown Equipment List (SWEL). This peer review was based on review of the SWEL Selection Report (REF 2)The guidance in Section 3: Selection of SSCs of the EPRI Technical Report (REF 1) was used as the basis for this review. Specifically, this peer review utilized the checklist in Appendix F: Checklist for Peer Review of SSC Selection of the EPRI Technical Report in Reference 1.Attachment 1 of this peer review report documents the completed checklist.
This peer review determined that the SSCs selected for the SWEL 1 seismic walkdowns represent a diverse sample of equipment required to perform the five safety functions and to meet the sample selection attributes, including: " Various types of systems" Major new and replacement equipment" Various types of equipment* Various environments" Equipment enhanced based on the findings of the IPEEE" Risk insight consideration For SWEL 2 development, the peer review determined that spent fuel related items were adequately considered and were appropriately included or excluded.This peer review resulted in no additional findings.
All peer review comments requiring resolution were incorporated prior to completion of the SWEL Selection Report.This peer review concludes that the process for selecting SSCs to be included on the Seismic Walkdown Equipment List appropriately followed the process outlined in Reference
: 1. It is further concluded that the SWEL sufficiently represents
: a. broad population of plant Seismic Category 1 equipment and systems to meet the objectives of the NRC 50.54(f) Letter.F-5
: 5. PEER REVIEW -SEISMIC WALKDOWN The peer review of the seismic walkdown was performed by the PR Teams on September 11-20, following the walkdowns for those days. Additional peer reviews occurred following the walkdowns as documented in this report.5.1 Review of Sample Checklists
& Area Walk-bys The peer review meetings consisted of each SWE Team (#1 and #2) presenting samples from their Seismic Walkdown Checklist (SWC) and Area Walk-by Checklist (AWC) that they had completed earlier that day. This peer review meeting following the day's walkdown activities allowed for immediate feedback between each walkdown team as well as common agreement on how some issues would be addressed.
Table 5-1 lists the sample of 14 components from each unit from the Seismic Walkdown Checklist (SWC) that were discussed in the peer review meetings.
These samples represent about 14% of each unit's SWEL population of 100 components.
The sample includes a variety of types of components (heat exchanger, valve, pump, tank, instrument rack, unit sub, transformer, fan, MCC, compressor, power panel, and control panel) and component locations (RHR pits, intake, RCA, DG Bldg, and Essential Switchgear room).Table 5-1 also lists the sample of 6 areas per unit from the Area Walk-by Checklist (AWC) that were discussed in the peer review. These samples represent about 20% of the total AWC population of 30 areas.When reviewing the components and areas during the afternoon peer review sessions, the following topics were addressed:
* Concrete cracks -For each team, concrete cracks were observed in the concrete floors where components were anchored.
Since the guidance does not give discretion for the significance of the crack, the peer review team agreed that the concrete cracks near anchorage should be recorded as "U" (unresolved).
Then, following further review, these findings could be changed to "YES" for minor surface cracks or "NO" for concrete crack near anchorage that may need further review." Physical interaction
-Several of the samples were examples of close spacing between the SWEL component and a hard object (such as a hand rail), with the potential for interaction.
In each case, the spacing was judged adequate, but this did reinforce the importance of careful field examination of each component." Seismic housekeeping
-Seismic housekeeping was assessed in each area and found to be acceptable.
Storage boxes were tied off or separated from equipment in designated areas.The presence of stanchions to rope off the protected train equipment was noted. It was agreed that these do not represent significant seismic risk due to the weight distribution (heavy base) and the light-weight nature of these stanchions.
F-6
" Seismic scaffolding
-A number of areas had scaffolding.
In each case, the scaffolding.
was carefully braced to provide seismic strength and documented on the scaffolding.
This was observed by both walkdown teams." Non-safety piping in SR buildings
-NS piping in all walk-by areas was observed to be well supported.

36 iii Executive Summary The purpose of this report is to provide information as requested by the Nuclear Regulatory Commission (NRC) in its March 12, 2012 letter issued to all power reactor licensees and holders of construction permits in active or deferred status. (Ref. 12) In particular, this report provides information requested to address Enclosure 3, Recommendation 2.3: Seismic, of the March 12, 2012 letter. (Ref. 12)The 50.54(f) letter requires, in part, all U.S. nuclear power plants to perform seismic walkdowns to verify the current plant configuration is within the current seismic licensing basis and identify and address degraded, non-conforming or unanalyzed conditions found. This report documents the seismic walkdowns performed at Turkey Point Unit 4 in response, in part, to the 50.54(o letter issued by the NRC.The Nuclear Energy Institute (NEI), supported by industry personnel, cooperated with the NRC to prepare guidance for conducting seismic walkdowns as required in the 50.54(f) letter, Enclosure 3, Recommendation 2.3: Seismic. (Ref.12).
The guidelines and procedures prepared by NEI and endorsed by the NRC were published through the Electric Power Research Institute (EPRI) as EPRI Technical Report 1025286, Seismic Walkdown Guidance for Resolution of Fukushima Near-Term Task Force Recommendation 2.3: Seismic, dated June 2012; henceforth, referred to as the "EPRI guidance document." (Ref. 1) Turkey Point has utilized this NRC endorsed guidance as the basis for the seismic walkdowns and this report. (Ref. 1)The EPRI guidance document was used to perform the engineering walkdowns and evaluations described in this report. In accordance with the EPRI guidance document, the following topics are addressed in the subsequent sections of this report.* Seismic Licensing Basis" Personnel Qualifications
* Selection of Systems, Structures, and Components (SSC)* Seismic Walkdowns and Area Walk-Bys* Seismic Licensing Basis Evaluations" IPEEE Vulnerabilities Resolution Report" Peer Review Seismic Licensing Basis The safe shutdown earthquake for the Turkey Point site is 0.15g horizontal ground acceleration and 0.10 g vertical ground acceleration. (Ref. 2, Section 2)iv Personnel Qualifications The walkdown team consisted of experienced site personnel with Civil/Structural or Mechanical Engineering, Operations and PRA backgrounds.
The site personnel were supplemented by two vendors with significant experience in the area of seismic design and the performance of seismic walkdowns.
The personnel who performed the key activities required to fulfill the objectives and requirements of the 50.54(f) letter are qualified and trained as required in the EPRI guidance document (Ref. 1).Selection of SSCs Ninety-eight (98) components were selected for the walkdown effort, including spent fuel pool items. These components were selected using the process described in detail in the EPRI guidance document, Section 3: Selection of SSCs. (Ref. 1)Seismic Walkdowns and Area Walk-Bys Section 5, Appendix C, and Appendix D of this report documents the equipment Seismic Walkdowns and the Area Walk-Bys.
The online seismic walkclowns for Turkey Point Unit 4 were performed September 17-21, 2012. The walkdown team consisted of two 2-person Seismic Walkdown Engineer (SWE) teams.The seismic walkdown team inspected 88 of the 98 components on the seismic walkdown equipment list (comprised of SWEL 1 and SWEL 2). Ten components were inaccessible and future walkdowns are planned for these items. Follow-up inspections are also to be performed on electrical panels that could not be opened at the time of the initial walkdown.Equipment Seismic Walkdowns included anchorage inspections and checks to verify as-found anchorages are consistent with design documents.
The walkdown found cases where the as-found anchorage was not consistent with the design document.
In other cases the document identifying anchorage design could not be identified.
Instances of anchor corrosion were cited, but the extent of corrosion is not a seismic capacity concern at this time. Except for the item E16A air handling unit (AH U), no concerns with overall anchorage strength were identified.
The E16A AHU was found to be lacking positive base anchorage.
The operability of the unit was addressed and the unit was found to be operable.Potential seismic interaction concerns were identified but none of the issues were considered to be hazards that rendered equipment inoperable.
Other equipment interaction issues are related to clearances between equipment and adjacent items and improper seismic housekeeping.
Loose or missing hardware, such as loose thumbscrews or latches, were found and cited under "Other" potentially adverse conditions.
Area Walk-Bys identified potentially adverse conditions relate to improper seismic housekeeping.
Potential seismic interaction concerns were also identified but none of the issues were considered to be significant immediate hazards. In some cases potential relay chatter due to bumping of equipment is cited. Potential relay chatter issue is undesirable but the overall plant hazard related to relay chatter is typically low.For the Turkey Point USI A-46 evaluation (Reference 9), relay chatter was dismissed as a concern. One potential seismically-induced spray hazard was cited as requiring evaluation.
v Seismic Licensina Basis Evaluations Conditions identified during the walkdowns were documented on the Seismic Walkdown Checklists (SWCs) and the Area Walkdown Checklists (AWCs), and entered into the CAP. For those conditions that operability or functionality could not be screened as acceptable, evaluations were initiated to demonstrate that the current licensing basis was met. Tables 5-2 and 5-3 in the report provide a summary of the conditions and the actions taken.IPEEE Vulnerabilities In lieu of a full IPEEE seismic analysis, FPL opted to submit a "scaled back" program to resolve USI A-46 and Generic Letter 87-02 as allowed by the NRC in a letter dated November 4, 1998 (Ref. 13) issued for the review of Turkey Point IPEEE evaluations.
The final results of this scaled back program for the A-46 program were submitted in a letter to the NRC, L-93-155, "Final Report of Plant Specific Seismic Adequacy Evaluation of Turkey Point Units 3 and 4 to Resolved USI A-46 and GL 87-02" (Ref. 14). The components selected for this analysis were also included in the SWEL in order to verify no outlier issues persisted.
Peer Reviews The Peer Review of the walkdowns consisted of two teams made up of Operations.
and PRA representatives and engineers with knowledge and experience in seismic inspections and assessments.
The engineers made up the SWE teams, but also served to peer review each other's work. The Operations and PRA representatives also participated in some of the walkdowns for logistical support as well as peer review.Appendix F of this report contains a summary of the Peer Review. The Peer Review determined that the objectives and requirements of the 50.54(f) letter are met. Further, it was concluded by the peer reviews that the efforts completed and documented within this report are in accordance with the EPRI guidance document.Summary In summary, seismic walkdowns have been completed at Turkey Point Unit 4 in accordance with the NRC endorsed walkdown methodology.
All potentially degraded, nonconforming, or unanalyzed conditions identified as a result of the seismic walkdowns have been entered into the corrective action program. None of the conditions found resulted in loss of operability or functionality of any structures, systems or components.
Follow-on activities required to complete the efforts to address Enclosure 3 of the 50.54(f) letter include inspection of items deferred due to inaccessibility along with supplemental inspections of electrical cabinets.
Area Walk-Bys will be complete, as required, during these follow-on activities.
vi 1 Introduction
 
==1.1 BACKGROUND==
 
In response to Near-Term Task Force (NTTF) Recommendation 2.3, the Nuclear Regulatory Commission (NRC) issued a 10CFR50.54(f) letter on March 12, 2012 requesting that all licensees perform seismic walkdowns to identify and address plant degraded, non-conforming, or unanalyzed conditions, with respect to the current seismic licensing basis. The Nuclear Energy Institute (NEI), through the Electric Power Research Institute (EPRI), prepared industry guidance to assist licensees in responding to this NRC request. The industry guidance document, EPRI Technical Report 1025286, Seismic Walkdown Guidance for Resolution of Fukushima Near-Term Task Force Recommendation 2.3: Seismic, dated June 2012 (Reference 1), was endorsed by the NRC on May 31, 2012. NextEra/Florida Power & Light Company (FPL)has committed to using.this guidance as the basis for completing the walkdown effort.-1.2 PLANT OVERVIEW The Turkey Point (PTN) site is located on the west shore of Biscayne Bay in Dade County, Florida. The site is 25 miles south of Miami and eight miles east of Florida City.The site contains two fossil units (Unit 1 and 2), two nuclear units (Units 3 and 4), and one combined cycle gas-powered unit (Unit 5). The plant's nuclear steam supply system (NSSS) was designed by Westinghouse Electric Corporation.
The Containment structure and balance of plant was designed by Bechtel Corporation.
The general description of the plant given above is based on the information in the UFSAR (Reference 2).1.3 APPROACH The EPRI Seismic Walkdown Guidance (Reference
: 1) was used for the seismic walkdowns and evaluations described in this report. In accordance with Reference 1, the following topics are addressed in the subsequent sections of this report: " Seismic Licensing Basis* Personnel Qualifications" Selection of SSCs" Seismic Walkdowns and Area Walk-Bys* Licensing Basis Evaluations
* IPEEE Vulnerabilities Resolution Report" Peer Review 1 2 Seismic Licensing Basis 2.1 SITE SEISMICITY Site seismicity is discussed in UFSAR (Reference
: 2) Section 2. On the basis of historical or statistical seismic activity, Turkey Point is located in a seismically inactive area, far from any recorded damaging shocks. Even though several of the larger historical earthquakes may have been felt in southern Florida, the amount of ground motion caused by them was not great enough to cause damage to any moderately well-built structure.
Predicated on history, building codes, geologic conditions, and earthquake probability, the design earthquake was conservatively established as 0.05 g horizontal ground acceleration.
The nuclear units have also been evaluated for a 0.15 g ground acceleration to assure no loss of function of the vital systems and structures.
Vertical acceleration is taken as 2/3 of the horizontal value and is considered to act concurrently.
 
===2.2 SEISMIC===
DESIGN BASIS The seismic design was based on the acceleration ground response spectrum curves shown in UFSAR Figures 5A-1 and 5A-2. The curves were derived from the "Housner Spectrum" normalized to 0.05g for the design earthquake and 0.15g for the maximum earthquake.
The UFSAR commitment for a maximum earthquake was determined at a time when probabilistic definition of seismic input had not been developed with any degree of consistency or confidence.
Therefore, the 0.15g PGA was conservatively estimated based on very limited data available at the time.The original design basis commits Turkey Point to the 1967 proposed version of General Design Criterion (GDC) Number 2 that relates to earthquake natural phenomena as identified below and is as follows: "Those systems and components of reactor facilities which are essential to the prevention or to the mitigation of the consequences of nuclear accidents which could cause undue risk to the health and safety of the public shall be designed, fabricated, and erected to performance standards that will enable such systems and components to withstand, without undue risk to the health and safety of the public the forces that might reasonably be imposed by the occurrence of an extraordinary natural phenomenon such as earthquake, tornado, flooding condition, high wind or heavy ice.The design bases so established shall reflect: (a) appropriate consideration of the most severe of these natural phenomena that have been officially recorded for the site and the surrounding area and (b) an appropriate margin for withstanding forces greater than those recorded to reflect uncertainties about the historical data and their suitability as a basis for design." 2 AEC Publication TID-7024 (Reference
: 4) was used as the basic design guide for earthquake analysis.
Floor response spectra were developed from the ground spectra for the Containment Buildings and Control Building to evaluate structures, systems, and components at the various elevations of those structures.
Earthquake forces were applied simultaneously in the vertical and any horizontal direction.
The vertical component of acceleration at any level was taken as two-thirds of the horizontal ground acceleration.
The damping factors for various types of construction are listed in Reference 2, Appendix 5A.For concrete structures and components, the basic code for determining the section strengths for original design was ACI 318-63 (Reference 5). For steel structures and components, the basic code for determining the section strengths was the AISC Steel Construction Manual, 6th Edition (Reference 6). Later codes were used for plant upgrades.
Design requirement for equipment varied by equipment type. The mechanical and electrical equipment were purchased under specifications that include a description of the seismic design criteria for the plant. Motor control centers and load centers were shake table tested to demonstrate no-loss-of-function capacity under the maximum hypothetical earthquake.
The Turkey Point units were within the scope of NRC unresolved safety issue (USI) A-46 (Reference 7), which required a re-evaluation of safety-related mechanical and electrical equipment.
At about the same time the NRC asked all operating power plants to undertake an investigation of design capability to extreme external events (Reference 8).Turkey Point resolved these issues as discussed in the next section. Resolution included implementation of seismic design improvements.
2.3 USI A-46 AND SEISMIC IPEEE Generic Letter 87-02, "Verification of Seismic Adequacy of Mechanical and Electrical Equipment in Operating Reactors, Unresolved Safety Issue (USI) A-46" (Reference 7)addressed seismic adequacy of equipment at older nuclear plants. Turkey Point Units 3 and 4 were within the scope of USI A-46.The evaluation of Turkey Point for resolution of USI A-46 is reported in Reference 9.FPL developed and implemented a plant specific program to satisfy requirements of USI A-46 as agreed between FPL and the USNRC. The program consisted of developing a walkdown procedure that concentrated on anchorage concerns of USI A-46, the seismic spatial interaction concerns of USI A-17 and the design concerns for large tanks in USI A-40. The program was developed by FPL to be appropriate, and cost effective for addressing GL87-02 concerns at its low seismic sites. The basic requirement for the walkdown was that the equipment be able to withstand the design basis SSE at the plant and still provide its safe shutdown function.
The procedure used relied on the judgment of an expert team to meet the basic requirement.
A success path of equipment using safety and non-safety equipment was selected for achieving hot shutdown of the plant within a period of 8 hours.An assessment of the anchorage adequacy was performed on each equipment item included on the safe shutdown list. This included an assessment of the seismic demand on the equipment anchorage (forces and stresses on the anchorage), the seismic capacity of the. anchorage components (attachment of the equipment to the anchorage, 3 the anchorage itself, and the development of the anchorage to the foundation), and whether the capacity of the weak link of the anchorage system exceeded the demand.A seismic spatial interaction assessment was performed on each equipment item included on the safe shutdown list. The following seismic spatial interaction issues were evaluated:
: 1) heavy objects falling (sometimes referred to as II over I interactions), 2)heavy objects sliding, swinging, vibrating or tipping (proximity interactions) and 3)inadequate flexibility of lines to accommodate seismic-induced relative movements between utility support points. An assessment was made as to whether possible interactions existed, and if it did, could the interaction preclude the equipment item from performing a safe shutdown function.
Those interactions identified as possibly precluding the equipment item's safe shutdown function were identified as outliers.The walkdown resulted in the identification of outlier equipment items with the majority of the outliers being lack of anchorage for electrical cabinets which were not previously required to be anchored.
FPL addressed all outlier issues listed and the actions taken are listed in Reference 9 Table 5.0. In many cases, FPL engineering generated Plant Change/Modification (PC/M) Packages which provided for physical modification to plant equipment resulting in additional seismic "hardening" of the equipment.
Generic Letter 88-20, Supplement 4, "Individual Plant Examination of External Events (IPEEE) for Severe Accident Vulnerabilities" (Reference 8), addressed plant-specific vulnerabilities to severe accidents.
For implementation of the IPEEE, Turkey Point was classified as a "reduced scope" plant per NUREG-1407 (Reference1O).
As such, the review level earthquake was equal to the site SSE and completion of the USI A-46 assessment largely satisfied the seismic IPEEE requirements.
FPL informed the NRC that the plant specific program developed for USI A-46 would be used to resolve GL 88-20 Supplement 4 at Turkey Point (see Reference 11).4 3 Personnel Qualifications

The summary of the Seismic Walkdown Equipment List is included in Appendix C under Table C-1 Summary of Seismic Walk~down Checklists.
The final SWEL (both SWEL 01 & SWEL 02)which details all of the component attributes used in the screening process, as well as the Master Component List, are on-file.7 5 Seismic Walkdowns and Area Walk-Bys 5.1 OVERVIEW The Seismic Walkdowns and Area Walk-Bys were conducted by 2-person teams of trained Seismic Walkdown Engineers, in accordance with the EPRI Seismic Walkdown Guidance (Reference 1). The walkdowns occurred on September 17-21, 2012.Components in the Containment building were inaccessible and will be inspected prior to the end of the first quarter in 2013 which falls within the window of the next refueling outage. The Seismic Walkdowns and Area Walk-Bys are discussed in more detail in the following sections.5.2 SEISMIC WALKDOWNS The Seismic Walkdowns focused on the seismic adequacy of the items on the SWEL as provided in Appendix B of this report. The Seismic Walkdowns also evaluated the potential for nearby SSCs to cause adverse seismic interactions with the SWEL items.The Seismic Walkdowns focused on the following adverse seismic conditions associated with the subject item of equipment:
* Adverse anchorage conditions
* Adverse seismic spatial interactions a Other adverse seismic conditions The results of the Seismic Walkdowns have been documented on the Seismic Walkdown Checklist (SWC) provided in the EPRI guidance document, Appendix C.Seismic Walkdowns were performed for 88 of the 98 items identified on the Turkey Point Unit 4 SWEL. The remaining items will be inspected in the refueling outage as previously noted. The associated SWCs are provided in Appendix C of this report.Additionally, photos have been included with most SWCs to provide a visual record of the item along with any comments noted on the SWC. These photos are not included to limit the size of this report but are on file. Drawings and other plant records are cited in some of the SWCs, but are not included with the SWCs because they are readily retrievable documents through the station's document management system.Inspection for certain items could not be completed due to access restrictions.
Appendix E of this report identifies the inaccessible equipment along with the plan for future Seismic Walkdowns.
The following subsections describe the approach followed by the SWEs to identify potentially adverse anchorage conditions, adverse seismic interactions, and other adverse seismic conditions during the Seismic Walkdowns.

====5.2.1 Adverse====
Anchorage Conditions Guidance for identifying anchorage that could be degraded, non-conforming, or unanalyzed relied on visual inspections of the anchorage and verification of anchorage configuration.
Details for these two types of evaluations are provided in the following two subsections.
The evaluation of potentially adverse anchorage conditions described in this subsection applies to the anchorage connections that attach the identified item of equipment to the civil structure on which it is mounted. For example, the welded connections that secure the base of a Motor Control Center (MCC) to the steel embedment in the concrete floor would be evaluated in this subsection.
Evaluation of the connections that secure components within the MCC is covered later in the subsection "Other Adverse Seismic Conditions." Visual Inspections The purpose of the visual inspections was to identify whether any of the following potentially adverse anchorage conditions were present:* Bent, broken, missing, or loose hardware* Corrosion that is more than mild surface oxidation* Visible cracks in the concrete near the anchors* Other potentially adverse seismic conditions Based on the results of the visual inspection, the SWEs judged whether the anchorage was potentially degraded, non-conforming, or unanalyzed.
The results of the visual inspection were documented on the SWC, as appropriate.
If there was clearly no evidence of degraded, nonconforming, or unanalyzed conditions, then it was indicated on the checklist and a licensing basis evaluation was not necessary.
However, if it was not possible to judge whether the anchorage is degraded, nonconforming, or unanalyzed, then the condition was entered into the Corrective Action Program as a potentially adverse seismic condition for further evaluation.
Additionally, any significant comments are noted on the SWCs. Drawings and other plant design documents are cited in some of the SWCs, but they are not included with the SWCs because they are readily available in the plant's electronic document management system.5.2.2 Anchorage Configuration Confirmation As required by the EPRI Seismic Walkdown Guidance (Reference 1, page 4-3), at least 50% of the items were confirmed to be anchored consistent with design drawings.
Line-mounted equipment (e.g., valves mounted on pipelines without separate anchorage) was notevaluated for anchorage adequacy and was not counted in establishing the 50%sample size.Examples of documentation that was considered to verify that the anchorage installation configurations are consistent with the plant documentation include the following:
* Design drawings" Seismic qualification reports of analyses or shake table tests 9 The SWC listed in Appendix C indicate the anchorage verification status for components as follows: N/A: component that is line-mounted and/or is not anchored to the civil structure and therefore does not count in the anchorage confirmation total.Y: component that is anchored to the civil structure and was chosen for anchorage configuration confirmation.
N: component which had anchorage but was not chosen for anchorage configuration confirmation.
See Table 5-1 below for the accounting of the 50% anchorage configuration confirmations, and the individual SWC forms in Appendix C for the specific documents used in each confirmation.
Total Items Chosen includes two deferred items.Table 5-1 :Anchorage Configuration Confirmation Total SWEL SWEL Items Minimum Total Items Items without Required Chosen Anchorage (N/A)98 29 35 37 5.2.3 Adverse Seismic Spatial Interactions An adverse seismic spatial interaction is the physical interaction between the SWEL item and a nearby SSC caused by relative motion between the two during an earthquake.
An inspection was performed in the area adjacent to and surrounding the SWEL item to identify any seismic interaction conditions that could adversely affect the capability of that SWEL item to perform its intended safety-related functions.
The three types of seismic spatial interaction effects that were considered are: " Proximity" Failure and falling of SSCs (Seismic II over I)o Flexibility of attached lines and cables Detailed guidance for evaluating each of these types of seismic spatial interactions is described in the EPRI guidance document, Appendix D: Seismic Spatial Interaction.
The Seismic Walkdown Engineers exercised their judgment to identify seismic interaction hazards. Section 5.2.5 provides a summary of issues identified during the Seismic Walkdowns.
 
====5.2.4 Other====
Adverse Seismic Conditions In addition to adverse anchorage conditions and adverse seismic interactions, described above, other potentially adverse seismic conditions that could challenge the seismic adequacy of a SWEL item were evaluated.
These inspections were mostly associated 10 with in-cabinet inspections of selected electrical equipment.
Examples of the types of conditions that could pose potentially adverse seismic conditions include the following: " Degraded conditions" Loose or missing fasteners that secure internal or external components to equipment" Large, heavy components mounted on a cabinet that are not typically included by the original equipment manufacturer
* Cabinet doors or panels that are not latched or fastened Any identified other adverse seismic conditions are documented on the items' SWC and Table 5-2, as applicable.
 
====5.2.5 Issues====
Identification during Seismic Walkdowns Table 5-2 provides a summary of issues identified during the equipment Seismic Walkdowns and recorded on SWCs. The tracking of issue resolution is identified in the table. Items are grouped based on the walkdown issue cited: " Anchorage issues* Seismic interaction issues" Other conditions
* Anchorage documentation not available" Anchorage inspection could not be fully completed Many of the potentially adverse anchorage conditions found are related to documentation of as-found anchorage.
In those cases either the as-found anchorage was not consistent with the available document, or the document identifying the anchorage design could not be identified.
Except for the item E16A air handling unit (AHU), no immediate concerns with overall anchorage strength were identified.
There are instances where anchor corrosion is cited, but the extent of corrosion is not an immediate seismic capacity concern. The E16A AHU was found to be lacking positive base anchorage.
Low seismic ruggedness of attached piping was also cited as a concern. The operability of the unit was addressed and the unit was found to be operable.Potential seismic interaction concerns were identified but none of the issues were considered to be significant hazards but will be addressed to reduce risk. Most equipment interaction issues are related to clearances between equipment and adjacent items and improper seismic housekeeping.
Under good seismic housekeeping practice, transient and moveable items (e.g., ladders) should be restrained or stowed such that they will not slide into or fall against important plant equipment.
Loose or missing hardware, such as loose thumbscrews or latches, were found and cited under "Other" potentially adverse conditions.
For items -requiring anchorage verification, the SWC anchorage verification checklist item was set to "Unknown" if an anchorage design document could not be found.Notwithstanding, the configuration was assessed to ensure that there was no immediate operability concern. Also, anchorage checklist items were set to "Unknown" when the walkdown team could not see all anchors. For example, some anchors (relatively few)11 of control cabinets were covered by wiring. A comment is included on the corresponding SWC to explain that certain anchors out of the group could not be seen. Again, the configuration was assessed to establish that there was no immediate operability concern.12 Table 5-2: Table of Actions Resulting from Seismic Walkdown Inspection Potentially Adverse Seismic Entered Equipment IDndition Resolution Current Status Condition into CAP Anchorage Issues This is a top supported MCC located at a low elevation.

28 5.3 AREA WALK-BYS The purpose of the Area Walk-Bys is to identify potentially adverse seismic conditions associated with other SSCs located in the vicinity of the SVVEL items. Vicinity is generally defined as the room containing the SWEL item. If the room is very large (e.g., Turbine Hall), then the vicinity is identified based on judgment, e.g., on the order of about 35 feet from the SWEL item. This vicinity is described on the Area Walk-By Checklist (AWC), shown in Appendix D of this report. A total of 47 AWCs were completed for Turkey Point Unit 4. Note that additional AWCs will be completed, as required, when deferred inspections are completed.
The key examination factors that were considered during Area Walk-Bys include the following:
* Anchorage conditions (if visible without opening equipment)
* Significantly degraded equipment in the area" A visual assessment (from the floor) of cable/conduit raceways and HVAC ducting (e.g., condition of supports or fill conditions of cable trays)* Potentially adverse seismic interactions including those that could cause flooding, spray, and fires in the area* Other housekeeping items that could cause adverse seismic interaction (including temporary installations and equipment storage)* Scaffold construction was inspected for adequate bracing and anchorage" Hazards from temporary equipment were evaluated and overall seismic housekeeping was evaluated The Area Walk-Bys are intended to identify adverse seismic conditions that are readily identified by visual inspection, without necessarily stopping to open cabinets or taking an extended look. If a potentially adverse seismic condition was identified during the Area Walk-By, then additional time was taken, as necessary, to evaluate adequately whether there was an adverse condition and to document any findings.The results of the Area Walk-Bys are documented on the AWCs included in Appendix D of this report. A separate AWC was filled out for each area inspected.
A single AWC was completed for areas where more than one SWEL item was located.Additional details for evaluating the potential for adverse seismic interactions that could cause flooding, spray, or fire in the area are provided in the following two subsections.
Seismically-Induced Floodinq/Spray Interactions Seismically-induced flooding/spray interactions are the effect of possible ruptures of vessels or piping systems that could spray, flood or cascade water into the area where SWEL items are located. This type of seismic interaction was considered during the IPEEE program. Those prior evaluations were considered, as applicable, as information for the Area Walk-Bys.One area of particular concern to the industry is threaded fire protection piping with long unsupported spans. If adequate seismic supports are present or there are isolation valves near the tanks or charging sources, flooding may not be a concern. Numerous 29 failures have been observed in past earthquakes resulting from sprinkler head impact.Less frequent but commonly observed failures have occurred due to flexible headers and stiff branch pipes, non-ductile mechanical couplings, seismic anchor motion and failed supports.-
Examples where seismically-induced flooding/spray interactions could occur include the following: " Fire protection piping with inadequate clearance around fusible-link sprinkler heads* Non-ductile mechanical and threaded piping couplings, can fail and lead to flooding or spray of equipment" Long, unsupported spans of threaded fire protection piping" Flexible headers with stiffly supported branch lines" Non-Seismic Category I tanks The SWEs exercised their judgment to identify only those seismically-induced interactions that could lead to flooding or spray. Fire protection piping at Turkey Point Unit 4 was found to be sufficiently restrained in areas where SC-I equipment items are located and no concerns were identified with fire protection piping.One potential seismic-induced spray interaction was identified at Turkey Point Unit 4 and included as an issue to be resolved.
This is related to the E16A AHU discussed in Section 5.2.Seismically-Induced Fire Interactions Seismically-induced fire interactions can occur when equipment or systems containing hazardous/flammable material fail or rupture. Examples where seismically-induced fire interactions could occur include the following: " Hazardous/flammable material stored in inadequately anchored drums, inadequately anchored shelves, or unlocked cabinets* Natural gas lines and their attachment to equipment or buildings* Bottles containing acetylene or similar flammable chemicals* Hydrogen lines and bottles Another example where seismically-induced fire interaction could occur is when there is relative motion between a high voltage item of equipment (e.g., 4160 volt transformer) and an adjacent support structure when they have different foundations.
This relative motion can cause high voltage busbars, which pass between the two, to short out against the grounded bus duct surrounding the busbars and cause a fire.The Seismic Walkdown Engineers exercised their judgment to identify only those seismically-induced interactions that could lead to fires. No potential seismic-fire interactions were identified for Turkey Point Unit 4.Area Walk-By Results Table 5-3 provides a summary of issues identified during the! Area Walkdowns and recorded on AWCs. The tracking of issue resolution is identified in the table. Items are grouped based on the walkdown issue cited: 30
* Seismic housekeeping issues" Other seismic interaction issues* Other conditions The majority of potentially adverse conditions found are related to seismic housekeeping.
Potential seismic interaction concerns were identified but none of the issues were considered to be significant immediate hazards. In some cases potential relay chatter due to bumping of equipment is cited. Potential relay chatter issue is undesirable but the overall plant hazard related to relay chatter is typically low. For the Turkey Point USI A-46 evaluation (Reference 9), relay chatter was dismissed based on the low probability along with being able to manage the effects if they were to occur. As stated, one potential seismic-induced spray hazard was cited as an item requiring evaluation.

For those conditions that required a seismic licensing basis evaluation, an operability screening has been performed and an evaluation will be performed to provide the final resolution to be documented within the corresponding condition reports. Table 5-2 and 5-3 of this report provide the status of the subject evaluations as applicable.
34 7 IPEEE Vulnerabilities Resolution Report As discussed in previously Section 2.3, for implementation of the IPEEE Turkey Point was classified as a "reduced scope" plant per NUREG-1407 (Ref. 10). As such, the review level earthquake was equal to the site SSE and completion of the USI A-46 assessment largely satisfied the seismic IPEEE requirements.
In lieu of a full IPEEE seismic analysis, FPL opted to submit a "scaled back" program to resolve USI A-46 and Generic Letter 87-02 as allowed by the NRC in a letter dated November 4, 1998 (Ref. 13) issued for the review of Turkey Point IPEEE evaluations.
The final results of this scaled back program for the A-46 program were submitted in a letter to the NRC, L-93-155, "Final Report of Plant Specific Seismic Adequacy Evaluation of Turkey Point Units 3 and 4 to Resolved USI A-46 and GL 87-02" (Ref. 14). The components selected for this analysis were also included in the SWEL in order to verify no outlier issues persisted.

Date Date Date 1%/I/ IR-Date B-1 1 Introduction This document contains the information used to develop the Seismic Walkdown Equipment List (SWEL) at Turkey Point (PTN) in accordance with EPRI Report 1025286, "Seismic Walkdown Guidance," dated June 2012 [1].The selection process was completed by applying separate screening criteria to develop SWELs 1 and 2. The documentation is laid out by first providing the screening criteria requirements, and then providing the implementation of how PTN applied that screening criteria.2 Process The general process focused first on building a Master Component List, with attributes to support the sample selection process (Sections 3 and 4). This list was obtained by generating a NAMS query of the entire PTN Equipment Database for all components along with data such as system code, component type, location, etc. Then the screening criteria below were applied to arrive at a final SWEL 1 and SWEL 2 comprised of about 92 items and 8 items, respectively.
The process also included identifying a set of plant locations around which the walkdown was organized (Section 5). The plant locations were also used to support the "walk-by" process to assess cable trays and ventilation ducts and the potential for seismic spatial interactions (Section 6).Finally, Section 6 identifies several evaluations that supported the identification of targets for the walkdown and the specific attributes that needed to be examined.Because the SWEL needs to address a number of attributes, the selection was performed and reviewed by a team that includes representatives from PRA, Operations, and Engineering.
This was done systematically by performing table-top virtual walkdowns and pre-walkdowns of each location to identify candidates for the SWEL as well as other issues (e.g., seismic-flood) that needed to be inspected by the walk-by.3 SWEL 1 Screening Criteria The final SWEL 1 is contained in the Microsoft Excel workbook, "U3 (U4) PTN Fukushima SWEL" [2], in the "SWEL 1" spreadsheet on-file. Each iteration of the screening process described below is contained in the Microsoft Access database, "SWEL 1 "[3].These final SWEL (both SWEL 01 & SWEL 02), as well as the Master Component List, are available in Excel format on-file at Turkey Point.3.1 Screening Criteria I -Seismic Category 1 Requirement The scope of SSCs (Systems, Structures, and Components) in the plant are limited to those that are designed to Seismic Category (SC) I requirements.
This is done because only such items have a defined seismic licensing basis against which to evaluate the as-installed configuration.
B-2 Selecting these items is intended to comply with the request in the NRC 50.54(f) Letter, under the "Requested Actions" section, to "verify current plant configuration with the current license basis." Application Seismic Class 1 SSCs include over 20,000 items in the PTN equipment database.
A complete equipment list from the PTN equipment database was obtained via a NAMS query ran in June 2012. The Seismic Class 1 SSCs were queried from the report by choosing only those SSCs where the Seismic Class was designated with an I.3.2 Screening Criteria 2 -Equipment or Systems Requirement The scope of SSCs included selecting only those that do not regularly undergo inspections to confirm that their configuration continues to be consistent with the plant licensing basis.Cable/conduit raceways and HVAC ductwork were not included as "equipment" in the SWEL 1, and were instead left to be reviewed during area walk-bys of the spaces containing items on the SWEL 1. Also omitted were SC 1 structures, containment penetrations, and SC1 piping systems.Application The list of all SC1 SSCs was further reduced by including only "active" components, removing all items classified as "design" or "non-equip".
 
===3.3 Screening===
 
Criteria 3- Supports 5 Safety Functions Requirement The scope of SSCs to be included in SWEL 1, are those SSCs associated with maintaining the five safety functions.
These five safety functions include the four safe shutdown functions (reactor reactivity control, reactor coolant pressure control, reactor coolant inventory control, and decay heat removal, which includes the Ultimate Heat Sink), plus the containment functions.
Application Since the PRA risk model represents the five safety functions listed above, a list of all PRA component tags was compared to the remaining SSCs. Items not included in the PRA model were removed.3.4 Screening Criteria 4- Sample Considerations Requirement It was expected that SWEL 1, taken as a whole, would include representative items from some of the variations within each of the following five attributes:
A variety of types of systems B-3 Major new and replacement equipment A variety of types of equipment A variety of environments
* Equipment enhanced due to vulnerabilities identified during the IPEEE program Application The seismic aspects of the PTN IPEEE were resolved by the use of the FPL site-specific Seismic Program associated with Unresolved Safety Issue (USI) A-46 [4]. The equipment analyzed in this program was used as a base and compared to the screening criteria above.The remaining components in the Master Component List were reordered according to system code, component type, and then location in order to obtain a broad sample. Operations personnel were consulted with to identify new or replaced equipment that were on the truncated Master Component List.4 SWEL 2 Screening Criteria SWEL 2 began with the same Master Component List as SWEL 1. An initial screening was done retaining only SSCs related to the Spent Fuel Pool system. Screening criteria 1, 2, and 3 for SWEL 2 were performed identically to that of screening criteria 1,2, and 4 for SWEL 1, respectively.
The final SWEL 2 is contained in the Microsoft Excel workbook, "U3 (U4) PTN Fukushima SWEL" [2], in the "SWEL 2" spreadsheet on-file. Each iteration of the screening process is contained in the Access database, "SWEL 2" [5].These Microsoft Excel Workbooks, as well as the Master Component List are available in Excel format on-file at Turkey Point.4.1 Screening Criteria 4 -Cause Rapid Drain-Down Requirement The EPRI guidance requires assessment of the potential for Spent Fuel Pool (SFP) rapid draindown, specifically the identification of SFP penetrations below about 10 feet above the top of the fuel assemblies.
Application There are only two penetrations in the SFP below this level. One is a lower suction valve (*-797), the other is the fuel transfer tube, used to move fuel from containment to the SFP. During normal operation, this tube is isolated by a blind flange on the containment side and a manual valve on the Fuel Storage Building side. Other components were included in this screening based on their importance in maintaining spent fuel pool inventory and cooling.B-4 5 Walk-By Table Each location will also be subject to a walk-by, an examination (in less detail) of the other PRA components, as well as an inspection for other seismic issues:* Several other passive component types: cable trays & ventilation ducts.* Seismic-induced fire. This includes all flammable materials in each location such as hydrogen lines, gas bottles (acetylene, hydrogen), natural gas lines, and hazardous/flammable material stored in the location.,* Seismic-induced flood. This includes all flood/spray sources (tanks, piping) originating in each location, based on the Internal Flood PRA. Note, the flood sources of interest are only those originating in the location, not those coming from another location.
The potential for flood propagation will be addressed in the seismic/flood analysis.* Spatial interactions (2 / 1). This includes adverse physical interaction due to proximity, failing of other components or structures (e.g., cranes), and flexibility of attached lines and cables.The final Walk-By Table is contained in the Microsoft Excel workbook, "U3 PTN Fukushima SWEL" [2], in the "Walkby Table" spreadsheet as well as the Master Component List are available in Excel format at Turkey Point on-file.6 Evaluations The following evaluations were performed prior to and during the walkdown to assess specific issues that may add to the walkdown scope or the inspection criteria.6.1 IPEEE or USI A-46 Vulnerabilities The seismic assessment performed for PTN USI A-46 was reviewed for any seismic vulnerability identified.
These issues were included in the SWEL table.6.2 Configuration Verification The EPRI guidance identifies two types of inspection for the walkdown: (a) visual inspection and (b) configuration verification.
Visual inspection is typically what is performed in a walkdown, looking for obvious degraded conditions in equipment anchorage.
However, configuration verification is a more involved inspection consistent with the existing plant documentation of the design basis. This is required in at least 50% of the SWEL items with anchorage.
Since 28 SWEL components are MOVs (Class 8) or AOVs (or similar Class 7 components) which do not have anchorage, this leaves 50% of 72, or at least 36 components; to be included in the configuration verification.
For those components, the design basis was reviewed and the key attributes included in the walkdown forms to assist the inspection.
6.3 New Equipment B-5 The EPRI Guidance directs that the SWEL should include a "robust sampling of the major new or replacement equipment installed within the past 15 years (i.e., since the approximate completion of the seismic IPEEE evaluation)".
Based on discussion with Operations and Engineering, major new or replacement equipment was identified and noted as such in the SWEL spreadsheet.
 
===6.4 Modifications===
The walkdown team allowed for changes to be made to the SWEL mid-walkdown.
Many components were changed from 'B' train to 'A' train as the former was the protected train, precluding the thorough inspection of some components.
Various items were also replaced or removed because they were common components already on the other unit's SWEL or the component was no longer installed in the plant.7 References

The tables below address three categories of equipment:
Table E-1 Item was completely inaccessible due to radiological, safety or other issues. Area corresponding to the item was also inaccessible.
Table E-2 Anchorage of item was internal and team was denied permission to open due to personnel hazard or hazard to plant operation.
Table E-3 Status of inspections of electrical cabinet for "Other Adverse Conditions" under SWC Check 11. For some cabinets, inspection did not include all compartments/sections because of safety concerns or hazard to plant operation.
The inspections for Turkey Point Unit 4 deferred components and inaccessible components will be performed prior to the end of the first quarter in 2013 which falls within the window of the next refueling outage. An action request (AR) has been issued to plan for and implement additional cabinet internal inspections.

f Date Date F-1
: 1. INTRODUCTION This report documents the peer review of the seismic walkdowns performed for Turkey Point Nuclear Station in September 2012, in support of the NRC Near Term Task Force (NTTF)Recommendation 2.3. This document describes the peer review team and process (Section 3), the peer review of the SWEL selection (Section 4), and the peer review of the seismic walkdown (Section 5).The peer review was performed consistent with Section 6 of the EPRI-TR-1 025286 (REF 1)guidance document and addresses the following specific activities: " Review of the selection of components for the Seismic Walkdown Equipment List (Section 4)" Review of a sample of the checklists prepared for the Seismic Walkdowns
& Walk-Bys (Section 5.1)" Review of any licensing basis evaluations (Section 5.2)" Review of the decisions for entering the potentially adverse conditions in to the plant's Corrective Action Program (Section 5.2)* Review of the final submittal report (Section 6).2. BACKGROUND This peer review covers three portions of the seismic walkdown: (a) the preparation of the SWEL, (b) the actual walkdown, and (c) the final submittal report.The Seismic Walkdown Equipment List (SWEL) was prepared in July and August and finalized in September, based on revisions that occurred during the walkdowns.
Section 3 describes the process of peer reviewing the SWEL.The vast majority of the seismic walkdowns occurred September 11 through September
: 20. The peer review of the walkdowns occurred in the afternoons of those same dates. This portion of the peer review is documented in Section 4.Two entire areas -the. containments
-were deferred for each unit for completion during each following respective outage. This allowed the walkdown to occur with less radiation exposure to the walkdown team.Four components could not be examined entirely with the bus powered: Essential 4KV switchgear Buses 3AB and 4AB, and the protected sequencers during walkdowns which were 3C23B and 4C23B. Consequently, the walkdowns for these components were postponed until the next scheduled outage when they can be scheduled to be removed from service for maintenance.
These inspection deferrals are being tracked under the Corrective Action Program (CAP) by two separate Actions Requests, one for each unit.F-2
: 3. PEER REVIEW TEAM & PROCESS The Turkey Point (PTN) Peer Review Team consisted of individuals from PTN operations, civil engineering, licensing, and PRA as well as structural/seismic engineers from Stevenson
&Associates.
These individuals participated in phases of preparation, performance, and peer review of the seismic walkdowns.
This section documents the peer review process and how the Peer Review Team interacted with the Seismic Walkdown Engineering Teams.3.1 Peer Review Team The affiliation, role, and qualifications for each Peer Review Team member are summarized in the following table.Name Group Role

Restrepo served as the Peer Review Team Lead. In that role, he was responsible for coordinating the peer review and assembling this report. As described below, he also performed some additional roles as part of the walkdown team PR. He also had the lead in the SWEL preparation, so he was not part of that PR process. As such, the SWEL was independently reviewed by a PRA Engineer from PSL, a Senior License Operator from PTN and one of the Peer Reviewers from PTN. Finally, he did not participate as an active team member during the seismic walkdown process and did not perform any other work besides the one described above. Therefore, his roll as the lead pear reviewer is considered acceptable F-3 SWEL Preparation The SWEL was prepared by A. Restrepo, who is a PTN PRA engineer, with PTN Operations experience and familiarity with the PTN IPEEE Report and the PTN PRA model.The SWEL was reviewed by a team that included a PRA engineer (G. Tullidge), a licensing engineer (T. Satyan Sharma), a civil engineer (A. Figueroa), and an Operations representative (T. Jones). All of these individuals are familiar with the design and layout of the plant and plant documentation.
Seismic Walkdown The primary seismic walkdown was conducted with two teams, each with two qualified structural/seismic engineers.
The Peer Review of the walkdowns consisted of a Peer Review Team Lead with Operations and PRA knowledge, and structural/seismic engineers.
The structural/seismic engineers made up the SWE teams, but also served to peer review each other's work. The Peer Review Team Lead also participated in many of the walkdowns for logistical support as well as peer review. The ultimate judgments regarding licensing basis were made by qualified PTN structural engineers." Seismic Walkdown Engineers (SWE):-SWE Team #1 -J. O'Sullivan (team lead), T.

PEER REVIEW -SELECTION OF COMPONENTS FOR SWEL The purpose of this section is to describe the process to perform the peer review of the selected components that were included in the Seismic Walkdown Equipment List (SWEL). This peer review was based on review of the SWEL Selection Report (REF 2)The guidance in Section 3: Selection of SSCs of the EPRI Technical Report (REF'I) was used as the basis for this review. Specifically, this peer review utilized the checklist in Appendix F: Checklist for Peer Review of SSC Selection of the EPRI Technical Report in Reference 1.Attachment 1 of this peer review report documents the completed checklist.
This peer review determined that the SSCs selected for the SWEL 1 seismic walkdowns represent a diverse sample of equipment required to perform the five safety functions and to meet the sample selection attributes, including: " Various types of systems" Major new and replacement equipment" Various types of equipment" Various environments" Equipment enhanced based on the findings of the IPEEE* Risk insight consideration For SWEL 2 development, the peer review determined that spent fuel related items were adequately considered and were appropriately included or excluded.This peer review resulted in no additional findings.
All peer review comments requiring resolution were incorporated prior to completion of the SWEL Selection Report.This peer review concludes that the process for selecting SSCs to be included on the Seismic Walkdown Equipment List appropriately followed the process outlined in Reference
: 1. It is further concluded that the SWEL sufficiently represents a broad population of plant Seismic Category 1 equipment and systems to meet the objectives of the NRC 50.54(f) Letter.F-5
: 5. PEER REVIEW -SEISMIC WALKDOWN The peer review of the seismic walkdown was performed by the PR Teams on September 11-20, following the walkdowns for those days. Additional peer reviews occurred following the walkdowns as documented in this report.5.1 Review of Sample Checklists
& Area Walk-bys The peer review meetings consisted of each SWE Team (#1 and #2) presenting samples from their Seismic Walkdown Checklist (SWC) and Area Walk-by Checklist (AWC) that they had completed earlier that day. This peer review meeting following the day's walkdown activities allowed for immediate feedback between each walkdown team as well as common agreement on how some issues would be addressed.
Table 5-1 lists the sample of 14 components from each unit from the Seismic Walkdown Checklist (SWC) that were discussed in the peer review meetings.
These samples represent about 14% of each unit's SWEL population of 100 components.
The sample includes a variety of types of components (heat exchanger, valve, pump, tank, instrument rack, unit sub, transformer, fan, MCC, compressor, power panel, and control panel) and component locations (RHR pits, intake, RCA, DG Bldg, and Essential Switchgear room).Table 5-1 also lists the sample of 6 areas per unit from the Area Walk-by Checklist (AWC) that were discussed in the peer review. These samples represent about 20% of the total AWC population of 30 areas.When reviewing the components and areas during the afternoon peer review sessions, the following topics were addressed: " Concrete cracks -For each team, concrete cracks were observed in the concrete floors where components were anchored.
Since the guidance does not give discretion for the significance of the crack, the peer review team agreed that the concrete cracks near anchorage should be recorded as "U" (unresolved).
Then, following further review, these findings could be changed to "YES" for minor surface cracks or "NO" for concrete crack near anchorage that may need further review." Physical interaction
-Several of the samples were examples of close spacing between the SWEL component and a hard object (such as a hand rail), with the potential for interaction.
In each case, the spacing was judged adequate, but this did -reinforce the importance of careful field examination of each component." Seismic housekeeping
-Seismic housekeeping was assessed in each area and found to be acceptable.
Storage boxes were tied off or separated from equipment in designated areas.The presence of stanchions to rope off -the protected train equipment was noted. It was agreed that these do not represent significant seismic risk due to the weight distribution (heavy base) and the light-weight nature of these stanchions.
F-6
" Seismic scaffolding
-A number of areas had scaffolding.
In each case, the scaffolding was carefully braced to provide seismic strength and documented on the scaffolding.
This was observed by both walkdown teams." Non-safety piping in SR buildings
-NS piping in all walk-by areas was observed to be well supported.
