16 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 Seabrook Station 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) Seabrook 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 Seabrook Station site is 0.25g horizontal ground acceleration and 0.17g vertical ground 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 ii 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).Selection of SSCs One hundred and two (102) components were selected for the walkdown effort, including spent fuel pool items. These components were selected as described 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 Seabrook Station Unit 1 were performed August 29-31, 2012 with additional walkdowns on September 14, 2012 to inspect selected electrical equipment and September 20, 2012 to inspect equipment in Containment.
The majority of the walkdown activities were conducted by two 2-person Seismic Walkdown teams.The seismic walkdown teams inspected 99 of the 102 components on the SWEL (comprised of SWEL 1 and SWEL 2). Walkdowns for 3 components were deferred due to accessibility issues resulting from energized equipment.
These 3 remaining 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 30 components. (Ref. 1) A total of 39 anchorage configurations were confirmed to be installed in accordance with the station documentation.
During the seismic walkdowns three (3) Condition Reports (CRs) were issued for conditions such as corrosion on structural supports.
After evaluation through the corrective action process, it was determined that none of the conditions identified in the CRs were adverse seismic conditions.
Seismic Licensing Basis Evaluations Conditions identified during the walkdowns were documented on the SWCs, AWCs, and entered into the CAP. For those conditions that required it seismic licensing basis evaluations were completed and documented within the CR. Tables 5-2 and 5-3 in the report provide the CR, a summary of the condition, 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).iii Peer Reviews The Peer Review of the walkdowns consisted of two teams made up of Operations and PRA representatives and structural/seismic engineers.
The structural/seismic 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 the Seabrook Station 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.Evaluations of the identified conditions are complete and documented within the CAP.These evaluations determined the Seismic Walkdowns resulted in no adverse anchorage conditions, no adverse seismic spatial interactions, and no other adverse seismic conditions associated with the items on the SWEL. 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 of long term structural integrity of supports as noted in Tables 5.2 and 5.3.The Seismic Walkdowns identified no degraded, nonconforming, or unanalyzed conditions that required either immediate or follow-on action(s).
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 3 items. These inspections are deferred because the cabinets were inaccessible due to the potential electrical hazard from energized buswork.iv 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 Energy Seabrook has committed to using this NRC-endorsed guidance as the basis for completing the walkdown effort.1.2 PLANT OVERVIEW Seabrook Station (SBK) consists of a pressurized water reactor (PWR) generating unit located in Seabrook, New Hampshire.
Seabrook has a containment building of concrete construction with a carbon steel liner. The unit is rated at 3648 MWth power, and was originally designed and constructed with joint participation by Westinghouse Electric Corporation, United Engineers
& Constructors, and Public Service Company of New Hampshire.
Seabrook began commercial operation in August 1990 (Seabrook Power Station Updated Final Safety Analysis Report (Reference 2), Section 1.1).1.3 APPROACH The EPRI Seismic Walkdown Guidance (Reference
: 1) was used for the Seabrook 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 The licensing basis for Seismic Category I (SC-1) equipment at Seabrook Station is defined in the UFSAR (Ref. 2) Section 3.7(B). Site design ground motion response spectra for the Safe Shutdown Earthquake (SSE) are provided in UFSAR Figures 3.7(B)-I, 3.7(B)-2 and 3.7(B)-3 and adhere to Regulatory Guide 1.60, Design Response Spectra for Seismic Design of Nuclear Power Plants (Reference 11). Damping values for SC-I equipment are listed in UFSAR Table 3.7(B)-i and conform to Regulatory Guide 1.61, Damping Values for Seismic Design of Nuclear Power Plants (Reference 12).As defined in UFSAR Section 2.5, the SSE is based on the postulated occurrence of a magnitude VIII(MM) earthquake located at the site. The horizontal peak acceleration associated with the maximum earthquake potential intensity VIII(MM) according to the intensity-acceleration relationship established by Trifunac and Brady (1975) is 0.25g (mean plus one sigma).Assuming that the vertical peak acceleration is two-thirds of the horizontal acceleration (Newmark and Hall, 1977), 0.167g is selected accordingly.
SC-i equipment is classified according to Regulatory Guide 1.29, Seismic Design Classification (Ref. 13), and is discussed in UFSAR Section 3.2.1, which states: "Category I structures, systems, and components are those that are important to safety and designed to remain functional in the event of a safe shutdown earthquake (SSE).These structures, systems, and components are those necessary to assure: 0 The integrity of the reactor coolant pressure boundary (RCPB).* The capability to shutdown the reactor and maintain it in a safe condition.
0 The capability to prevent or mitigate the consequences of accidents that could result in potential offsite exposures.
In addition, Seismic Category I structures, systems, and components are designed to remain functional and within applicable stress and deformation limits (elastic range of materials) when subjected to the effects of the vibratory motion of the operating basis earthquake (OBE) in combination with normal operating loads." Per UFSAR Section 3.10(B).1, SC-I electrical equipment within the UE&C scope of supply was qualified per the guidelines recommended in IEEE Standard 344-1975 and Regulatory Guide 1.100, similar to current requirements for nuclear Safety Related components.
Per UFSAR Section 3.10(N).1 SC-i electrical equipment within the Westinghouse scope of supply was qualified per IEEE Standard 344-75 (Ref. 14).Mechanical equipment was qualified per the requirements of ASME B&PV Code, Section III, Subsections NB, NC or ND, 1971, 1974 and later addenda.2 For concrete structures and components, the basic code for determining the section strengths is ACI 318-71 (Ref. 15), or later.For steel structures and components, the basic code for determining the section strengths is the AISC Steel Construction Manual, 7th Edition (Ref. 16) or later.3 3 Personnel Qualifications

SELECTION PERSONNEL The SWEL development was performed by a member of the Seabrook PRA Group. The SWEL was then independently reviewed by another member of the PRA Group, plant personnel from Operations, and finally by personnel from the Structural Engineering department at Seabrook.3.4 SEISMIC WALKDOWN ENGINEERS The seismic walkdown teams (SWT) consisted of four seismic walkdown engineers (SWEs), two from Stevenson and Associates (S&A) and two from Seabrook Station. The SWTs were lead by senior consultants from S&A, with support from Seabrook's Structural Engineering Group. For the containment walkdown, the SWT consisted of qualified Seabrook staff members.Other Seabrook professional staff participating in some of the walkdowns included those from Seabrook Operations as well as their PRA group.The lead SWE on each walkdown team was an engineer from Stevenson and Associates (S&A). S&A is recognized internationally as leading seismic consultants to the nuclear industry and as regular contributors to the advancement of earthquake engineering knowledge through funded research projects.
The professional staff has expertise and capabilities in earthquake engineering, structural dynamics, and structural design. Over the past 35 years S&A has performed seismic evaluations of US nuclear power plants using either Seismic Probabilistic Risk Assessment (SPRA) or Seismic Margin Assessment (SMA) to address US Nuclear Regulatory Commission (NRC) requests for Individual Plant Evaluation for External Events (IPEEE).3.5 LICENSING BASIS REVIEWERS The Licensing Basis Reviewers for Seabrook consisted of the four seismic walkdown engineers:
two from Seabrook and two from S&A. The Seabrook engineers had the lead in licensing basis determinations, with support from the S&A engineers.
 
===3.6 IPEEE===
REVIEWERS The IPEEE Reviewers for Seabrook consisted of two PRA engineers, who 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 In addition to the team roles listed above, one Senior Reactor Operator (SRO), participated in the SWEL review and walkdown review as the Operations representative.
The SRO from Seabrook Station who participated has numerous years of experience in various aspects of plant operations and operations training.5 Various other 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 final SWEL (both SWEL 01 & SWEL 02), as well as the Master Component List, are included in the SWEL Selection Report in Appendix B.7 5 Seismic Walkdowns and Area Walk-Bys 5.1 OVERVIEW The Seabrook Seismic Walkdowns and Area Walk-Bys were conducted by two 2-person teams of trained Seismic Walkdown Engineers, in accordance with the EPRI Seismic Walkdown Guidance (Reference 1). The majority of the walkdowns occurred on August 29 -31, 2012. An additional walkdown was performed by one 2-person team on September 14, 2012 to perform internal inspections for other adverse seismic conditions of selected electrical equipment cabinets that were not completely inspected or were not opened at all during the initial inspections.
Components in the Containment building were inspected on September 20, 2012, when radiological conditions permitted during the plant's 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
* 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 99 of the 102 items identified on the Seabrook (SBK) SWEL. The completed SWCs are provided in Appendix C of this report. 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.Seismic Walkdowns are deferred for the remaining 3 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 1 0CFR50.54(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 8 adverse seismic conditions during the Seismic Walkdowns.
 
====5.2.1 Adverse====
Anchorage Conditions Guidance for identifying an 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, including any significant comments, were documented on the SWCs, 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.
 
====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 in pipelines without separate anchorage) was not evaluated for anchorage adequacy and therefore not counted in establishing the 50%,sample size.Examples of documentation that were 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 table of contents for Appendix C indicates the anchorage verification status for components as follows: N/A: 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.
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)/2 102 42 30 39 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)" 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:
10
" 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.
The equipment Seismic Walkdowns resulted in a total of two (2) actions identified and each of these was entered into the station's CAP. All of the identified concerns were assessed and it was concluded that the condition would not prevent the associated equipment from performing its safety-related function(s).
None of the conditions identified by the SWEs during the equipment Seismic Walkdowns were concluded to be adverse seismic conditions.

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 28 AWCs were completed for SBK. 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 completed 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 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.13 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:
* 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 Seabrook is laterally braced throughout the power block and no concerns associated with fire protection piping or spray of equipment were identified.
Seabrook fire protection piping follows an installation specification developed by the architect/engineering organization for the installation of fire suppression systems which in turn follows NFPA standards for the seismic design.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 Seabrook.14
 
====5.3.1 Issue====
Identification during Area Walk-bys None of the anomalies or issues identified by the SWEs during the area walk-bys was ultimately judged to be "Potentially Adverse Seismic Conditions" because in all cases it was concluded that the anomaly or issue would not prevent the equipment from performing its safety-related function.
Table 5-3 at the end of this section shows only one (1) issue identified in the Area Walk-bys.15 Table 5-3: Table of Actions Resulting from Area Walk-by Inspections Equipment ID Potentially Adverse Seismic Resolution Entered Current Status Condition Into CAP?Walkdown / evaluation of pipe support determined that the functionality of support is PB412, PAB El.

Support member is robust and the corrosion is on the surface only. This is not a degraded condition.
16 6 Licensing Basis Evaluations As noted in Sections 5.2 and 5.3, the issues identified during the Seismic Walkdowns and Area Walk-Bys were not determined to be "Potentially Adverse Seismic Conditions" because in all cases the anomaly or issue would not prevent the equipment from performing its safety-related function.
Therefore, no formal Licensing Basis Evaluations were necessary and none were performed.
17 7 IPEEE Vulnerabilities Resolution Report The seismic assessment performed for the Seabrook IPEEE Report (Ref. 4) was reviewed and no seismic vulnerabilities were identified.
No plant improvements were required as a result of the seismic portion of the IPEEE. (See page 2 of the NRC SER on IPEEE (Ref. 10).18 8 Peer Review The Peer Review Report is included as Appendix F.

===2.3 Walkdown===
Seabrook Station November 2012 Prepared by -A" Ken Kiper (SWEL Selection Lead)Reviewed by Rich Turcotte (PRA roupF-Reviewed by Reviewed by rce'e6u on (E-ngineering)
Date Date Oat Date I Introduction This document summarizes the process for selecting the components to be included in the seismic walkdown equipment list (SWEL) for Seabrook Station. This process is consistent with guidance in EPRI-TR-1025286(REF
: 1) and meets the intent of NRC NTTF Requirement 2.3.The SWEL walkdown locations are summarized in Table 1, along with walk-by attributes.
The final Seabrook SWEL is included in Attachment A. Components were generally chosen from Train B since Train A was the protected train during the planned walkdown period.The SWEL list was revised during the seismic walkdowns in August & September 2012 based on accessibility of anchorage.
See Section 4 for details.2 Process The general process focuses first on building a Master Component List, with attributes to support the sample selection process (Section 3). Then a sample of Seismic Category 1 (SC1)components is made for the SWEL to assure the five safety functions are represented along with a variety of systems, environments, and component types.The process also includes identifying a set of plant locations around which the walkdown is organized (Section 4). The plant locations are also used to support the "walk-by" process to assess cable trays and ventilation ducts and the potential for seismic spatial interactions (Section 5).Finally, Section 6 identifies several evaluations that support the identification of targets for the walkdown and the specific attributes that need 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 need to be inspected by the walk-by.3 Master Component List The SWEL was developed starting from the components list in the Seabrook internal events pRA(REF 2) (SWEL 1). This list contains risk important components from the internal events PRA, one of the attributes from the EPRI guidance.
Other components were added that are implicitly modeled in the PRA (e.g., instrument racks).This list includes components related to the five safety functions
-reactivity control, RCS pressure control, RCS inventory control, decay heat removal, containment function -implicitly by including components from both core-damage-frequency (CDF) and large-early-release-frequency (LERF) sequences.
The five safety functions are addressed further in Section 4.1 (Screen #3).This list was expanded to include components associated with the Spent Fuel Pool (SWEL 2).The guidance described these as "SFP SCl equipment and systems" and includes specifically components associated with SFP cooling. Per the guidance, the SF pool structure is excluded from the walkdown.
Thus, this added all SFP-related components that are Seismic Cat 1, B-2 including pumps, valves, heat exchangers, ventilation fans, etc. In addition, the potential for rapid draindown of the SFP was evaluated (see Section 4.2, Screen #4). The conclusion of that evaluation was that there are no components that could lead to rapid draindown.
Thus, the list did not need to be expanded.Specific attributes were identified for each component to support the sample selection, as described below:* Seismic Class. Each component in the master list was identified as SC1 or non-SC1.The SWEL generally applies only to SCI since this is primarily a design-basis evaluation.
* System. For each component in the master list, the associated system was identified.
This attribute is used to assure that the equipment selection includes a variety of types of systems." Location.
For each component in the master list, the location (room ID) was identified.
The walkdowns are organized by plant location (see Section 4). This also assures that the equipment selection includes a variety of environments.
* Equipment Class. For each component in the master list, the "equipment class" was identified.
The equipment classes are the 21 types of equipment identified in Appendix B of the EPRI guidance document (see Table 2). This attribute is used to assure that the equipment selection includes a variety of types of equipment.
e New/Replacement Equipment.
Only one of the components in the master list was identified as major new or replacement equipment in the last 15 years -the control panel DG-CP-907-B (DG-B temperature control) in the DG Bldg. Some of the equipment has been replaced (e.g., PCCW motors), but with like-kind equipment." Equipment Enhanced from IPEEE. As described in Section 6.1, no plant improvements were made as a result of the seismic portion of the IPEEE assessment.
The Master Component List is included in Attachment B (referred to as Base List 1 & Base List 2 in Section 8 of the EPRI guidance).
4 Walkdown List (SWEL)The SWEL was created by sampling from the Master Component List, using the attributes identified in Section 3. The final SWEL is contained in Attachment A.First, plant locations are defined to support the walkdown.
A list of 11 locations (buildings or sets of rooms) were identified that contain the primary components from most of the top ten risk-important systems, as well as the Fuel Storage Bldg. Table 1 provides this list of walkdown locations.
This focuses the walkdown on risk-important systems, consistent with the guidance to"... include consideration of the importance of the contribution to risk for the SSCs." Within these 11 locations, a total of 102 components was identified from the Master Component List (98 in SWEL 1 and 4 in SWEL 2). As shown in Attachment A, this process assured that a variety of systems, environments and equipment classes are represented.
This sample was also reviewed by Operations and Engineering to assure these components were accessible and that the anchorage was visible.B-3 The SWEL list was revised during the seismic walkdowns in August & September 2012 based on accessibility of anchorage.
The following modifications were made:* 4 deletions The fans on the Cooling Tower roof (1-SW-FN-51-B
& 2-SW-FN-51-B) were examined, but only half of the bolts could be observed.
Similarly, the ventilation fan (EAH-FN-31-B) and air conditioner (EAH-AC-2-B) in the Containment Enclosure Ventilation Area were examined but anchorage could not be fully observed.* 3 substitutions Power panel EDE-PP-1 12-B was included in place of EDE-PP-1 1 -B, since PP-111-B anchorage could not be observed.
Pump CS-P-3-A was included in place of CS-P-3-B, since the access to P-3-B was more difficult.
Inside containment, AOV CC-V-1 76 was included in place of COP-V-2 due to accessibility.
* 1 addition Control panel DG-CP-907-B (DG-B temperature control) was added as a new component of the last few years.The final count of SWEL components was 102.4.1 Screening for SWEL I The screening process for SWEL 1 meets the requirements of the EPRI-TR as described below:* Screen #1 Seismic Category 1 Non-seismic-category 1 components are screened out of the Master Component List.This screening was performed using the "Safety-Related" attribute in Master Component List, since Safety Related components are also Seismic Category 1. This was verified using UFSAR Table 3.2-2 "Design of Structures, Components, Equipment, and Systems."* Screen #2 Equipment or Systems Components selected for the SWEL 1 were those that do not undergo regular inspection to confirm their configuration.
Thus, SCI structures, containment penetrations, and SC1 piping systems were excluded.
As a result, the SWEL includes mechanical and electrical equipment plus tanks and heat exchangers (as demonstrated in Screen #4, "equipment type" below).* Screen #3 Supports Five Safety Functions The SWEL includes components from all five safety functions, as follows: 1. Reactivity Control" Emergency Boration (Boric acid pump, tanks);" Support systems (AC power, DC power).2. RCS Pressure Control* Secondary pressure control (ASDV, MSIV)3. RCS Inventory Control e ECCS (SI pump, RH pump, MOVs, RWST)B-4
* Support systems (AC power, DC power, EAH ventilation, CC pumps & MOVs).4. Decay Heat Removal e Secondary heat removal (EFW pump, EFW MOVs, CST, ASDV);* RHR shutdown cooling (RHR pump & MOVs, CC pumps & MOVs, SW pumps &MOVs, heat exchangers,);
e Support systems (AC power, DC power, EFPH ventilation, EAH ventilation, SWA ventilation).
: 5. Containment Function* Containment isolation (CC valve, MSD valves)* Containment spray injection (CBS pump, RWST)* Containment spray heat removal (CBS pump, CBS heat exchanger, CC pumps &MOVs, SW pump & MOVs)* Support systems (EAH ventilation, CC pumps & MOVs, AC power, DC power).* Screen #4 Sample Considerations The SWEL includes components from various systems, environments, and types: " System. The SWEL includes components from a number of types of systems -power support systems (EDE, DG), cooling support systems (SW, CC), ventilation systems (DAH, SWA, EAH), hot shutdown systems (EFW, CO), ECCS (RH, SI), containment spray (CBS), and spent fuel cooling (SF)." Environment.
The SWEL includes components from a number of locations in most of the major SCi buildings on site -PAB, Control Bldg, DG Bldg, EFW pumphouse, Cooling Tower, Containment.
These locations involve different environments, from ventilation controlled areas (DG Bldg) to outside areas (CST, Cooling Tower roof);from areas with normally running equipment (PAB) to areas with normally standby equipment (Cooling Tower). These locations involve different environments related to elevation, from (-)61' elevation in the RHR equipment vault to (+)46' elevation in the Cooling Tower. pump room.B-5 The following table summarizes the count of components by location.SWEL Count of Location Building Name Components SWEL-01 SW Cooling Tower 11 SWEL-02 DG Bldg Train B 17 SWEL-03 CB Essential SWGR Train B 12 SWEL-04 Emergency Feedwater Pumphouse 9 SWEL-05 MS/FW Pipe Chase (East) 7 SWEL-06 RHR Equipment Vault Train B 15 SWEL-07 Refueling Water Storage Tank 3 SWEL-08 PAB 25' Elevation 17 SWEL-09 Containment Enclosure Ventilation Area 2 SWEL-1 0 Containment 5 SWEL-1 1 Fuel Storage Bldg 4 TOTAL 102 Equipment Type. The SWEL includes components from most of the 21 equipment classes. Table 2 provides a list of the 21 equipment classes. The following table shows the SWEL count by equipment class. As noted below and in Table 2, only Class 10 (air handler), Class 11 (chiller), and Class 13 (motor generator) components were not represented on the SWEL.B-6 Equipment Class Count of Components (01) 480V MCC 3 (02) 125 VDC SWGR 1 (02) 480V unit sub 2 (03) 4 KV SWGR 1 (04) transformer 2 (05) motor-driven pump 11 (06) pump (vertical drive) 2 (07) AOV 13 (07) electro-hydraulic valve 1 (07) pneumatic damper 2 (08) MOV 26 (09) fan 5 (12) compressor 1 (14) power panel 2 (15) battery 1 (16) battery charger 1 (16) inverter 1 (17) diesel generator 1 (18) instrument rack 4 (19) temperature device 5 (20) control panel 6 (21) heat exchanger 5 (21) tank 6 Note: Air conditioner EAH-AC-2-B, representing equipment classes 10 and 11 (Air Handler and Chiller) was originally on the SWEL. However, during walkdown the EAH-AC unit was examined but the anchorage could not be completely verified.
As a result, this component was removed from the walkdown scope.4.2 Screening for SWEL 2 The screening process for SWEL 2 meets the requirements of the EPRI-TR as described below:* Screen #1 Seismic Category I Non-seismic-category 1 components related to SFP cooling are screened out of the Master Component List. This screening was performed using the "Safety-Related" attribute in Master Component List, since Safety Related components are also Seismic Category 1. This was verified using UFSAR Table 3.2-2 "Design of Structures, Components, Equipment, and Systems."* Screen #2 Equipment or Systems Components selected for the SWEL 2 were those that do not undergo regular inspection to confirm their configuration.
Thus, SC1 structures including the SF Pool and SC1 B-7 piping systems were excluded.
As a result, the SWEL includes mechanical and electrical equipment plus heat exchangers (as demonstrated in Screen #3, "equipment type" below).* Screen #3 Sample Considerations The SWEL 2 includes components from a variety of systems, environments, and types: o System. The systems in SWEL 2 include SF (spent fuel) system, FAH (Fuel Storage Bldg ventilation), and CC (cooling to SF heat exchangers)." Environment.
The SWEL 2 includes components are all located in the Fuel Storage Bldg, involve different environments related to elevation, from (+)7' elevation in the SF pump area to +64' in the ventilation area.* Equipment Type. The SWEL 2 includes components from four of the 21 equipment classes.* Screen #4 Rapid Draindown The EPRI guidance requires assessment of the potential for SFP rapid draindown, specifically the identification of SFP penetrations below about 10 feet above the top of the fuel assemblies.
The only penetration in the SFP below this level 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 Bldg side. The blind flange is a passive structural member that is judged to be out of scope for this evaluation.
Thus, there are no SFP penetrations that could fail from a seismic event and lead to rapid draindown.
The EPRI guidance includes "determine how pool sloshing would reduce the initial volume of water in the SFP during a seismic event." This is required only if components related to rapid draindown were identified that could not be inspected.
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.Table 1 provides an initial assessment for each location to assist the walk-by process.B-8 6 Evaluations The following evaluations were performed prior to the walkdown to assess specific issues that may add to the walkdown scope or the inspection criteria.6.1 IPEEE Vulnerabilities The seismic assessment performed for the Seabrook IPEEE Report(REF
: 3) was be reviewed for any seismic vulnerabilities identified.
Several plant improvements were made in response to fire analysis and external flood and high winds analysis in the IPEEE. However, no plant improvements were made as a result of the seismic portion of the IPEEE. (See NRC SER on IPEEE(REF 4), page 2).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 42 SWEL components are MOVs (Class 8) or AOVs (or similar Class 7 components) which do not have anchorage, this leaves 50% of (102 -42), or at least 30 components to be included in the configuration verification.
This resulted in a total of 39 components that are identified in Attachment A. 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 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, only one new or replacement equipment was identified in the 11 walkdown locations

: 11. Have you looked for and found no adverse seismic conditions that No could adversely affect the safety functions of the equipment?
No: Impact loading is possible at top right edge of CP-108-B.Between CP-108B and MCC-631, a steel shim appears wedged into the 3/8" wide gap near the top. It is welded to roof of CP- 1 08-B (which is 96" high and shorter than adjacent MCC-631) but does not appear to be fastened to the MCC. Impact on MCC appears to be on a conduit entry box.Unknown if above is a relay chatter issue. If CP-108-B does not contain essential relays then the concern may be dismissed.

PSA (permanent storage area) #PAB-25-11 has a storage cabinet that is 72" tall and could topple onto IR 1-MM-IR-20C but there is nothing vital on rack thus no issue (to be confirmed).
Instrument Rack 1-MM-IR-20-C is not nuclear safety, not Class 1 E, and not trip critical.

Date F-1 I Introduction This report documents the peer review of the seismic walkdowns performed for Seabrook Station in August and 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 on August 29, 30, & 31, with two teams the first two days and a single team on the last day. The peer review of the walkdowns occurred in the afternoons of August 29 & 30. This portion of the peer review is documented in Section 4.One area -containment
-was walked down separately on Sept 19, during the OR1 5 refueling outage. This allowed the walkdown to occur with less radiation exposure to the walkdown team.Three components could not be examined entirely with the bus powered: essential 4KV switchgear Bus E6, and unit substations US61 & US64. Consequently, the walkdown for these components was postponed to the next scheduled outage when Bus E6 is scheduled to be removed from service for maintenance.
These inspection deferrals are being tracked by See CAP (Bus E6) and (US 61 & US64).F-2 3 Peer Review Team & Process The Seabrook Peer Review Team consisted of individuals from Seabrook operations, structural engineering, and PRA as well as structural/seismic engineers from Stevenson
& Assoc. These individuals participated in phases of preparation, performance and peer review of the seismic walkdowns.

As described below, he also F-3 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.* SWEL Preparation The SWEL was prepared by K. Kiper, who is the lead Seabrook PRA engineer, with experience and familiarity with the Seabrook IPEEE Report and Seabrook Seismic PRA.The SWEL was reviewed by a team that included a PRA engineer (R. Turcotte), design structural engineer (B. Bouton), and Operations representative (T. Cassidy).
All of these individuals are familiar with the design and layout of the plant and plant documentation." Lead -K. Kiper* PR Team for SWEL -R. Turcotte, B. Bouton, T. Cassidy* 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 two teams made up of Operations representative (T. Cassidy), PRA representatives (K. Kiper, R.Turcotte), and structural/seismic engineers (B. Bouton, S. Kenrick, W. Djordjevic, J.O'Sullivan).
The structural/seismic 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. The ultimate judgments regarding licensing basis were made by qualified Seabrook structural engineers (B. Bouton, S. Kenrick)." Seismic Walkdown Engineers (SWE):-SWE Team #1 -W.

Bouton F-4 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..(REF 2)review was based on review of the SWEL Selection Report (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 walkdowns was completed by the PR Teams on August 29 & 30, following the walkdowns for those days. Additional peer reviews were conducted following the walkdowns as documented in this report.5.1 Review of Sample Checklists
& Area Walk-bys The peer review meetings on August 29 & 30 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 that morning. This peer review meeting following the day's walkdown activities allowed for an immediate information exchange and feedback on walkdown observations between each walkdown team as well as common agreement on how observation 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 component samples represent about 25%of the total SWEL population of 102 components.
The sample includes a variety of component"types" (e.g., heat exchanger, valve, pump, tank, instrument rack, unit substation, transformer, fan, motor control center, compressor, power panel, and control panel) and variety of component "locations" (e.g., RHR vault, PAB, Tank Farm, SW cooling tower, 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 area samples represent about a third of the total AWC population of 29 rooms. These areas included the RHR vault, PAB, Tank Farm, SW cooling tower, DG Bldg, and Essential Switchgear room.Tables 5-1 and 5-2 document observations made by the walkdown teams that form the basis for the peer review. The following topics were addressed by each team: " Concrete Cracks -Cracks were observed in the concrete floors in the vicinity of where components were anchored.
Since the guidance does not give discretion for the significance of the crack, the peer review team agreed that concrete cracks located near anchorage should be recorded as "U" (unresolved) finding. Then, after follow-up review, these findings could be changed to "YES" if the crack is a minor surface crack or "NO" if the concrete crack is located near anchorage, is more than a minor surface crack, and may need further detailed evaluation." Physical Interaction
-Several of the component samples provided an example of close spacing between the SWEL component and a hard object (such as a fixed structural support or a hand rail), with the potential for seismic interaction.
In each case, the close spacing was judged to provide adequate clearance, but this did reinforce the importance of careful field examination of each component for potential seismic/spatial interaction." Seismic Housekeeping
-Seismic housekeeping was assessed in each area and found to be acceptable.
Storage boxes were tied off or physically separated from equipment in designated areas. The presence of stanchions used to display signs or to rope off protected train equipment was noted. It was agreed that these stanchions do not represent a significant seismic risk due to tipping or lateral movement because: (1) the stanchions typically have a heavy base and very low center of gravity, and (2) overall, the stanchions have relatively light weight and are adequately tethered at the base to prevent significant lateral movement during a seismic event.F-6
" Seismic Scaffolding
-Erected scaffolding was observed in a number of areas. In each case, the scaffolding was carefully and adequately braced in multiple lateral directions to prevent the scaffolding from interacting with other equipment during a seismic event. All scaffolding was erected by procedure with the controlling permit documented and displayed at each scaffolding.
This was observed by both walkdown teams." Non-safety Piping in Safety Related Buildings
-Non-safety piping in all walk-by areas was observed to be well supported with lateral restraints.
No significant issues were identified from the peer review team discussions.
 
===5.2 Review===
of Licensing Basis Evaluations
& Corrective Action Process The final report provides a list of the anomalies encountered during the Seabrook seismic walkdown inspections and how they were addressed.
The review of those anomalies demonstrates a thorough and reasonable process for addressing open issues. There were no comments offered by the peer review team.6 Review Final Submittal Report & Sign-off The final submittal report has been reviewed by Seabrook representatives from structural engineering, Operations, and the PRA Group. Comments were provided to assure the final report meets the requirements of the EPRI 1025286 -Seismic Walkdown Guidance (REF. 1)7 References

The space below each question in this checklist should be used to describe any findings identified during the peer review process and how the SWEL may have changed to address those findings.
Additional space is provided at the end of this checklist for documenting other comments.1. Were the five safety functions adequately represented in the SWEL 1 selection?
YO Nn Requirement met.Remarks: No issues identified during peer review. The SWEL development included various components that support each of the five key safety functions.
The functions include: reactivity control, RCS pressure control, RCS inventory control, decay heat removal and containment.
The linkage between safety function and component is based on insights from the Seabrook PRA and design basis information and is demonstrated in the SWEL Selection document.2. Does SWEL 1 include an appropriate representation of items having the following sample selection attributes:
: a. Various types of systems? YN ND-Requirement met.Remarks: No issues identified during peer review. The SWEL development specifically included components from various types of systems. Specifically, the components represent the major front line and support systems that are considered important from a PRA perspective such as injection, heat removal, cooling water, ventilation and power systems. Also included are components associated with spent fuel pool cooling.b. Major new and replacement equipment?
YM NO Requirement met.Remarks: No issues identified during peer review. SWEL development included a review of new or replacement equipment was performed; this review identified only one component having recent installation; this being the new DG temperature control panel DG-CP-907B.
Other major components have been replaced over the years but with like components (example CCW pump motors) and these are captured in the SWEL.F-8 Peer Review Checklist for SWEL c. Various types of equipment?
Y Requirement met. N Remarks: No issues identified during the peer review. The SWEL included components from almost all of the suggested equipment types. The only type of equipment not explicitly evaluated was the EAH-AC-2 unit (air handler/chiller).
This component was excluded because the anchorage could not be completely verified.
This not withstanding, no issues were identified during the examination.
Overall, the SWEL is comprehensive with regard to examining a variety of different types of components.
: d. Various environments?
y Requirement met. N Remarks: No issues identified during the peer review. SWEL components were located in many different areas of the plant including containment.
Many areas have roughly the same indoor environment, representative of normal operating conditions with both operating and standby equipment.
These environments are judged representative of the environments that would be expected during a random seismic event. Also, normal and accident environments are judged to play a minor role in the adequacy of seismic anchorage.
: e. Equipment enhanced based on the findings of the IPEEE (or equivalent) program? Y Requirement met. N Remarks: No issues identified during the peer review. The Seabrook Station IPEEE was independently reviewed during the peer review to confirm that there were no seismic design enhancements recommended or implemented as a result of the external events risk study.f. Were risk insights considered in the development of SWEL 1? Y Requirement met. N Remarks: No issues identified during the peer review. The SWEL was originally developed from the components list in the Seabrook internal events PRA. This list specifically identifies risk important components.
Based on peer review of the SWEL, the SWEL is judged to include a good cross section of risk significant and SC-I components representing the features important to both core damage mitigation and release mitigation.
F-9 Page 12 of 12 Peer Review Checklist for SWEL 3. For SWEL 2: a. Were spent fuel pool related items considered, and if applicable included in SWEL 2?Requirement met.Remarks: No issues identified dunng the peer review. Components associated with spent fuel pool are specifically included in the SWEL 2 walkdown list. The EPRI screening criteria were also used in the development of the SFP SWEL 2 list and addressed:
seismic category, equipment and system types, sample considerations, and potential for rapid drain down. The SWEL 2 component list represents a good sampling of the major SFP components.
: b. Was an appropriate justification documented for spent fuel pool related items not included in SWEL 2?Requirement met.Remarks: No issues identified during the peer review. SWEL 2 component selection process is essentially the same as the SWEL I selection process and is documented in the SWEL selection report.YM NO YM NE 4. Provide any other comments related to the peer review of the SWELs.Overall, the SWEL 1 and SWEL 2 component lists are comprehensive and have a reasonable basis consistent with the ERPI / industry selection process. The walkdown of SWEL I and SWEL2 components will provide a comprehensive indication of the overall seismic health status of all Seabrook Station SC-1 systems/components.
: 5. Have all peer review comments been adequately addressed in the final SWEL? YM NE Peer review comments (editorial in nature) have been incorporated into the SWEL selection document.
This did not result in any changes to the SWEL lists themselves.
