E-1 12Q4116-RPT-001 Rev. 0 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. 5) In particular, this report provides information requested to address Enclosure 3, Recommendation 2.3: Seismic, of the March 12, 2012 letter. (Ref. 5)The 50.54(f) letter requires, in part, all U.S. nuclear power plants to perform seismic walkdowns to identify and address degraded, non-conforming or unanalyzed conditions and to verify the current plant configuration is within the current seismic licensing basis. This report documents the seismic walkdowns performed at St. Lucie Plant Unit 1 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. 5) 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) St. Lucie 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 Licensinq Basis The design basis earthquake (DBE) for the St. Lucie Plant site is 0. 1Og horizontal ground acceleration.

The vertical earthquake is defined as 2/3 of the horizontal earthquake acceleration. (Ref. 2 section 3.7)Personnel Qualifications The walkdown team consisted of experienced site personnel with Civil, Operations and PRA backgrounds.

The site personnel were supplemented by two vendors with significant experience in the areas 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). Personnel qualifications are discussed in Section 3 of this report.ii 12Q4116-RPT-001 Rev. 0 Selection of SSCs One hundred (100) components were selected for the walkdown effort, including spent fuel pool items.These components were selected as 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 St. Lucie Plant Unit 1 were performed October 1-5, 2012. The walkdown team consisted of two 2-person Seismic Walkdown Engineer (SWE) teams.The seismic walkdown team inspected 88 of the 100 components on the SWEL (comprised of SWEL 1 and SWEL 2). Walkdowns for 11 components were deferred due to accessibility issues relating to energized equipment or equipment being located within containment.

These 11 remaining Unit 1 items will be walked down during a unit outage or another time when the equipment is accessible, as appropriate.

Anchorage verification was required for a minimum of 39 components. (Ref. 1) A total of 42 anchorage configurations were confirmed to be installed in accordance with the station documentation.

During the seismic walkdowns at St. Lucie Unit 1, several Action Requests (ARs) were issued for a variety of conditions, which are detailed in Tables 5-2 and 5-3. After evaluation through the Corrective Action Program (CAP), it was determined that none of the conditions identified in the ARs were adverse seismic conditions that challenged the plant licensing basis.Seismic Licensing Basis Evaluations Conditions identified during the walkdowns were documented on the SWCs, AWCs, and entered into the CAP. Conditions that required seismic licensing basis evaluations were completed and documented within Section 6: Licensing Basis Evaluations of this report. Tables 5-2 and 5-3 in the report provide a summary of the conditions and the action completion status.IPEEE Vulnerabilities No vulnerabilities were identified as a result of the effort that addressed the Individual Plant Examination of External Events (IPEEE).Peer Reviews The Peer Review of the walkdowns consisted of one team made up of two representatives and two structural/seismic engineers.

The structural/seismic engineers made up the SWE team, but also served to peer review each other's work. Section 8 and 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 the St. Lucie Plant Unit 1 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.iii 12Q4116-RPT-001 Rev. 0 Evaluations of the identified conditions are complete and documented within the CAP. These evaluations determined the Seismic Walkdowns resulted with no adverse anchorage conditions, no adverse seismic spatial interactions, and no other adverse seismic conditions associated with the items on the SWEL that challenged the plant licensing basis. Similarly, the Area Walk-Bys resulted with no adverse seismic conditions associated with other SSCs located in the vicinity of the SWEL item(s).The Seismic Walkdowns identified several minor issues predominantly pertaining to maintenance and housekeeping.

No planned or newly identified protection or mitigation features have resulted from the efforts to address the 50.54(f) letter.Follow-on activities required to complete the efforts to address Enclosure 3 of the 50.54(f) letter include inspection of 11 items that could not be inspected at the time of the walkdown.

Of the 11 items, 6 were electrical cabinets that could not be opened due to potential electrical hazard from energized buswork and 5 were items that are located within containment.

These 11 items will be inspected during a future outage.iv 12Q4116-RPT-001 Rev. 0 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. St. Lucie has committed to using this NRC-endorsed guidance as the basis completing the walkdown effort.1.2 Plant Overview Florida Power & Light Company's (FPL) St. Lucie site consists of two pressurized water reactor (PWR)generating units located on Hutchinson Island in St. Lucie County, Florida approximately 7 miles to the south of the city of Ft. Pierce. The eastern boundary of the site is the Atlantic Ocean and the western boundary is the Indian River, a tidal lagoon. Other prominent natural features within 50 miles of the site include Lake Okeechobee, 30 miles to the west-southwest of the site and a portion of the Everglades approximately 24 miles to the south of the site. The plant's nuclear steam supply system (NSSS) is a pressurized water reactor designed by Combustion Engineering Incorporated.

The net electrical output is approximately 890 Mwe per unit. The containment structure and balance of plant are designed by Ebasco Services Incorporated.

1.3 Approach

The EPRI Seismic Walkdown Guidance (Reference

1) was used for the St. Lucie 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* Seismic Licensing Basis Evaluations

• IPEEE Vulnerabilities Resolution Report* Peer Review 1 12Q4116-RPT-001 Rev. 0 2 Seismic Licensing Basis The licensing basis for Seismic Class I (SC-1) equipment at St. Lucie Plant is defined in the UFSAR (Ref.2) Section 3.7. Site design ground motion response spectra for the Operating Basis Earthquake (OBE)and Design Basis Earthquake (DBE) are based on the Housner spectral shape provided in UFSAR Figures 3.7-1 and 3.7-2. The DBE is that which could produce the maximum vibratory acceleration at the site as determined from evaluation of seismic and geologic information.

The OBE and DBE damping values for buildings, piping and SC-i equipment are listed in UFSAR Section 3.7.1.3.The entire state of Florida is by all accounts a low seismicity region of the United States having been a Zone 0 area by the Uniform Building Code [Ref. 2.3] which means no seismic design loads for"conventional" buildings.

The original design operating basis earthquake was conservatively set to a horizontal 0.05g peak ground acceleration (PGA) and the design basis earthquake (DBE) was set to 0. 1Og by requirement of 1OCFR100, Appendix S. The vertical earthquake is 2/3 of the horizontal component and applied simultaneously with one horizontal component.

The term "Seismic Class I" as used herein corresponds to the term "Category I" as used in the "Standard Format and Content of Safety Analysis Reports for Nuclear Power Plants", February 1972. No seismic classifications are made on the basis of plant operability, hence no additional seismic classes or categories have been established.

Seismic Class I structures, systems and components have been designed to withstand loadings due to the design basis earthquake (DBE):* without loss of function or fluid boundary integrity if they are needed for safe plant shutdown or to mitigate the effects of a LOCA* without failure of fluid boundary integrity if such failure could result in significant uncontrolled releasez of radioactivity to the emnvironment" without loss of function if such function is needed to detect or prevent potential significant uncontrolled release of radioactivity to the environment or if such function is needed to detect conditions requiring plant shutdown.Per UFSAR Section 3.9 Mechanical equipment was qualified by testing and analysis.

Manufacturers were required to test equipment to floor response spectra provided for the location where the equipment was located or by analysis where stresses were limited to 90% of material yield stress for the DBE loading cases or by experience demonstrating the sufficient margin. Seismic static factors for various equipment are given in Table 3.9-1. For active Code Class 1, 2 and 3 mechanical components St. Lucie followed Regulatory Guide 1.48 for testing pumps and valves to demonstrate operability for loadings which included seismic. St. Lucie followed the requirements of the draft ASME Code for Pumps and Valves (Ref. 3). Valve motor operators supplied on St. Lucie 1 were manufactured by Limitorque.

These operators are representative of the prototype units that were successfully seismically tested in accordance with Ogden Technology Laboratories Report No. 7192-9 dated 9/26/72 and Lockheed Electronics Company Test Report No. 2120-4594 dated July 31, 1968, and No. 2539A-4723 dated 2 12Q4116-RPT-001 Rev. 0 September 23, 1973. These reports show that the operators comply with the intent of IEEE Standard 344-1971 requirements.

For Code Class 1, 2 and 3 piping St. Lucie 1 performed dynamic analysis and followed the requirements and stress limits of ANSI B31.7.For electrical equipment purchase specifications for seismic Class I instrumentation and electrical equipment contain horizontal and vertical seismic acceleration values based on the DBE spectra for the equipment location.

Where there is a possibility of amplification or the floor response acceleration due to equipment supports, the specified acceleration values are increased to account for such amplification.

Manufacturers were also supplied the floor response spectra for the equipment location.

It was required to ensure that the natural period of vibration of the component did not fall within the critical frequency range of the floor response spectra. Qualification documentation was required to demonstrate that the component was capable of functioning under the specified seismic loadings.

The qualification data could consist of prototype test results, mathematical analysis or operational experience.

Per UFSAR Section 3.10, SC-1 electrical equipment was qualified per follow the guidelines recommended in IEEE Standard 344-1971, "IEEE Guide for Seismic Qualification of Class 1 E Electric Equipment for Nuclear Power Generating Stations" even though it was not in existence at the time the construction permit was granted.For concrete structures and components, the basiccode for determining the section strengths is ACI 318-63, Part IVB for Ultimate Strength Design (USD). Steel design and construction followed AISC,"Specification for the Design, Fabrication and Erection of Structural Steel for Buildings," 1969.3 12Q4116-RPT-001 Rev. 0 3 Personnel Qualifications

5 12Q4116-RPT-001 Rev. 0 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 final SWEL (both SWEL 01 & SWEL 02) is included in the SWEL Selection Report in Appendix B.6 12Q4116-RPT-001 Rev. 0 5 Seismic Walkdowns and Area Walk-by's 5.1 Overview The St. Lucie Seismic Walkdowns and Area Walk-Bys were conducted by two trained Seismic Walkdown Engineers in accordance with the EPRI Seismic Walkdown Guidance (Reference 1). The walkdowns occurred October 1-5, 2012. Selected electrical equipment cabinets that were not completely inspected or were not opened at all during the inspections due to unavailability were deferred to a future unit outage or another time when the equipment is accessible, as appropriate.

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 and a SWC completed for 88of the 100 items identified on the St. Lucie Plant Unit 1 SWEL. The completed SWCs along with any comments are provided in Appendix C of this report. Drawings andother 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.Seismic Walkdowns are deferred for the remaining 11 items until safe access conditions can be provided.These items could not be walked down during the 180-day period following the issuance of the 10CFR50.54(f) letter due to their being inaccessible because they were energized and required for safe plant operation.

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 7 12Q4116-RPT-001 Rev. 0 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.

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:

• Design drawings" Seismic qualification reports of analyses or shake table tests The table of contents for Appendix C indicates the anchorage verification status for components as follows: NIA: components that are line-mounted and/or are not anchored to the civil structure and therefore do not count in the anchorage confirmation total.Y: components that are anchored to the civil structure which were confirmed.

to be consistent with design drawings and/or other plant documentation N: components which had anchorage but were not chosen for anchorage configuration confirmations.

8 12Q4116-RPT-001 Rev. 0 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 drawings used in each confirmation.

Table 5-1: Anchorage Configuration Confirmation Total SWEL SWEL Items Minimum Total Items Items without Required to Confirmed Anchorage (NIA) Confirm A B (A-B)/2 100 23 39 42 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 earthquakel 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)" 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.

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" Other adverse conditions Any identified other adverse seismic conditions are documented on the items' SWC and Table 5-2, as applicable.

5.2.5 Issues

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 35 AWCs were completed for St.Lucie 1. It is noted that additional AWCs will be completed, as required, as deferred and supplemental 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 to meet the station administrative procedure for the control of scaffolding.

Seismic housekeeping was examined to meet the station procedure for the control of temporary equipment, temporary power, job setup, and plant storage.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.MUUILIUIdCAI Utdalls Wor evdludully otený JULUtial for adverse seismic interactions that could cause flooding, spray, or fire in the area are provided in the following two subsections.

Seismically-Induced Flooding/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 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:

13 12Q4116-RPT-001 Rev. 0" 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 Class I tanks The SWEs exercised their judgment to identify only those seismically-induced interactions that could lead to flooding or spray. No concerns associated with fire protection piping or spray of equipment were identified at St. Lucie 1.Seismically-Induced Fire Interactions Seismically-induced fire interactions can occur when equipment or systems containing hazardous/flammable material fail or rupture. 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.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 such interactions were found at St. Lucie 1.5.3.1 Issues Identification during Area Walk-bys Table 5-3 provides a summary of issues identified during the Area Walk-bys.

The Area Walk-bys resulted in several conditions requiring action and each of these was entered into the station's CAP by St. Lucie Plant site personnel (PSL).

St. ituce :Ngcb~ar $tatitim R evision 0 Noveiber' 2D1-?rqcparWd by.Reviewed by Reviee -.by-, Dale D.ate Sharanr*Ra-miimi' (Eng dog), B-I 12Q4116-RPT-001 Rev. 0 1 Introduction This document contains the information used to develop the Seismic Walkdown Equipment List (SWEL)at St. Lucie (PSL) 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 sequenced by first providing the screening criteria requirements, and then applying the screening criteria to the development and implementation of the seismic walkdown equipment list (SWEL).2 Process The general p.rocess 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 PSL 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 approximately 100 items for each Unit.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 included representatives from PRA, Operations, and Engineering.

3 SWEL 1 Screening Criteria The final SWEL 1 is listed in Attachment

1.3.1 Screening

Criteria I -Seismic Category i 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.

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 An equipment list from the PSL equipment database was obtained via a Nuclear Asset Management System (NAMS) query. The Seismic Class 1 SSCs were queried from the report by choosing only those SSCs designated as Seismic Class I.3.2 Screening Criteria 2 -Equipment or Systems B-2 12Q4116-RPT-001 Rev. 0 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.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" 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 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 identical to that of screening criteria 1,2, and 4 for SWEL 1, respectively.

The final SWEL 2 is incorporated into the PSL1 & PSL 2 SWEL.B-3 12Q4116-RPT-001 Rev. 0 4.1 Screening Criteria 4 -Cause Rapid Drain-Down Requirement The EPRI guidance requires assessment of the potential for Spent Fuel Pool (SFP) rapid drain down, specifically the identification of SFP penetrations below approximately 10 feet above the top of the fuel assemblies.

Application Components were included in this screening based on their importance in maintaining spent fuel pool inventory and cooling.5 Walk-By Table Each location was also subjected to a walk-by, an examination (in less detail) of the other SSCs, 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 flobd. 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.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 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.

6.2 New Equipment The EPRI Guidance directs that theSWEL 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.

B-4 12Q4116-RPT-O01 Rev. 0 6.3 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.

Yes 3. Is the anchorage free of corrosion that is more than mild surface oxidation?

No Moderate surface corrosion on nuts & bolts wino indication of strength loss.At bottom, however, steel mounting bracket has lost area so bottom bolt is ineffective.

Three other bolts remain effective and given low mass of FT, no loss of functionality for seismic event, kicker brace is degraded at connection to structure steel. Given fixed connection of FT vertical members & low mass, kicker brace judged to be acceptable for functionality of FT during seismic event. PSL generated AR and WR to address issue.4.

Introduction

.This report documents the peer review of the seismic walkdowns performed for St. Lucie Plant, Unit 1, 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 August and finalized in October, 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 on October 1-5, 2012. One member of the peer review team was present for all of the seismic walkdowns.

This portion of the peer review is documented in Section 4.Six components could not be examined entirely with the bus powered: 1. 4.16KV Switchgear 1A3-1 2. 480V Pressurizer Bus 1A3 3. 480V Motor Control Center 1A7 4. 480V Switchgear 1 B2 5. 480V Switchgear lAB 6. 4.16KV Switchgear lAB Five components were located inside Unit 1 containment, which is currently in operation.

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 12Q4116-RPT-001 Rev. 0 5. Peer Review -Seismic Walkdown The peer review of the seismic walkdown was performed by the individual PR Team members on each day of the walkdowns.

The Seismic Walkdown Engineers (SWE) were accompanied by at least one member of either the Operations or Engineering Peer Review team during the walkdown.

Additional peer review occurred following the walkdowns as documented in this report.5.1 Review of Sample Checklists

& Area Walk-bys The peer review meetings were performed on the following morning for the walkdowns that were performed the previous day. The SWE presented samples from their Seismic Walkdown Checklist (SWC) and Area Walk-by Checklist (AWC) that they had completed that morning. This peer review meeting following the previous day's walkdown activities allowed for immediate feedback between each walkdown team. as well as common agreement on how issues would be addressed.

Table 5-1 lists the sample of 25 components from the Seismic Walkdown Checklist (SWC) that were discussed in the peer review meetings.

These samples represent about 25% of the total SWEL population of 100 components.

The sample includes a variety of types of components (heat exchanger, valve, pump, tank, instrument rack, transformer, fan, MCC, compressor, power panel, and control panel) and component locations (Reactor Aux Bldg, Steam Trestle, Refueling Water Tank, DG Bldg, and Essential Switchgear room).Table 5-2 lists the sample of 10 areas from the Area Walk-by Checklist (AWC) that were discussed in the peer review. These samples represent about 25% of the total AWC population.

These areas included Reactor Aux Bldg, Steam Trestle, Refueling Water Tank, DG Bldg, and Essential Switchgear room.These tables document observations from the walkdown teams that formed the basis for the peer review. The following topics were addressed: " Seismic Housekeeping

-Seismic housekeeping was assessed in each area and found to be acceptable.

In areas where equipment was in-service, work carts were tied off or separated from equipment in designated areas.The presence of stanchions and signs to identify protected train equipment was also noted. In most cases 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.

At one location the sign was identified as being significant enough to be seismically adverse and was removed immediately by the Operations team member.A number of panels were identified With missing and or loose bolting or latches. In most cases these were not considered to be seismically adverse." Concrete cracks -Minor concrete cracks were observed in the concrete floors or grout pads where components were anchored.

The location, cause of the cracking, and potential impact on the seismic capacity VVa ,Nu conditions were identified that adverseiy impacted the seismic capacity.

Corrosion of anchors or welds was identified on a couple of items. Due to the available design margin the identified corrosion was not considered to adversely impact the design basis of the component.

These issues were entered into the corrective action program to remove the existing corrosion, perform detailed inspection and repair to restore design margin as required.e Physical interaction

-Several of the samples were examples of close spacing between the SWEL component and a hard object (such as a concrete/block walls), 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 scaffolding

-A number of areas had scaffolding.

In each case, the scaffolding was noted to be 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.

No significant issues were identified from the peer review team discussions.
