Purpose

The lateral stiffnesses of the vertical support (two structural angles) attached to the operator of Air-OperatedValve AO-0-33-0241 D and the pipe support (square structural tubing) attached downstream of the valve atthe pipe elbow are calculated. The lateral stiffnesses of the supports are compared to help judge whetherthe valve being supported at two different locations (the diesel room wall and the top of the diesel enginebase frame) could potentially cause damage to the valve during a seismic event.

Note that angle stiffness is multiplied bytwo since there are two supports.

The lateral stiffness of the pipe support is an order of magnitude stiffer than the support at the valveoperator. Thus, if there is any differential motion between the wall of the diesel room and the diesel enginebase frame during a seismic event, the support at the valve operator will easily displace without impartingsignificant load to the valve operator. Additionally, a structural joint was not observed between the floor ofthe diesel room and the wall of the diesel room so any differential displacement between these twolocations will be very small. The diesel engine baseframe is securely attached to the floor, and the baseframe is very stiff, so the top of the base frame (where the operator support is anchored) should displacewith the floor.

E.2. ASSESSMENT OF ELECTRICAL CABINET INTERNAL INSPECTIONS

All electrical cabinets on the SWEL require assessment of the need for inspections toaddress the potential for "other adverse seismic conditions" internal to the cabinet. Thisassessment is required due to an NRC clarification of their expectations for seismicwalkdowns, which was received after the online seismic walkdowns were completed.Tables E-2 (for Unit 3) and E-3 (for Unit 0) list all electrical items that requireassessment. Accessibility of equipment, basis for accessibility determination,completion date of internal inspections, tracking number (if internal inspection has notyet been performed) and inspection results are provided in these tables.

Mr. Swanner is a degreed aerospace engineer with 20 years of nuclear plantexperience. Mr. Swanner has been trained as a Seismic Capability Engineerand EPRI Seismic Walkdown Engineer (SWE).

Mr. Butler, Ms. Schlaseman and Mr. Swanner are registered professional engineers.

F.1.3 SWEL DEVELOPMENT

The SWEL development was performed by Mr. Benjamin Frazier. The initial peer reviewof the SWEL development was performed by Mr. Butler and Mr. Swanner, and wasconducted between August 2, 2012 and August 16, 2012. There were no comments asnoted on the SWEL Peer Review Checklist and no findings were cited. The completedSWEL Peer Review Checklist is found in Attachment 1. The discussion for the SWELdevelopment peer review is provided in Section 2. Note that due to equipmentaccessibility including ALARA and electrical safety concerns, changes to the SWEL weremade as the walkdowns were conducted. The Peer Review Team did review changesmade during the walkdown and has reviewed the final SWEL included in Appendix B ofthe Walkdown Report. As noted in the SWEL Peer Review Checklist, there were noitems from EPRI Equipment Classes 11, Chillers; 12, Air Compressors; or 13, MotorGenerators. This was because there is no safety-related Seismic Class I equipment inthese classes at PBAPS Unit 3. Also, due to the significant number of modificationsperformed in the late 1990's as part of the USI A-46 (SQUG) and IPEEE programs,PBAPS Unit 3 has not made significant modifications to Seismic Class I equipmentwithin the last several years.

F.1.4 SEISMIC WALKDOWN

The on-site peer review of the seismic walkdowns was performed by Mr. Butler andMs. Schlaseman on August 30, 2012. The on-site and follow-up reviews includedapproximately 26% of the total SWCs and approximately 50% of the total AWCsapplicable to the equipment for Unit 3 and common, including checklists, photos, anddrawings where applicable. Interviews were conducted with both teams of SWEs toassess conduct of the walkdowns and adherence to the EPRI Seismic WalkdownGuidance (Reference 1). The discussion of the review of the sample of SeismicWalkdown Checklists (SWCs) and Area Walk-By Checklists (AWCs) is provided inSection 3.

The assessment of Issue Reports (IRs) with respect to current licensing basis isprovided in Sections 5 and 6 of the report. These assessments and their outcomes werealso discussed with the SWE inspection team in order to completely understand theissues.


F.2Peer Review - Selection of SSCs

F.2.1 PURPOSE

The purpose of this section is to describe the process to perform the peer review of theselected structures, systems, and components, (SSCs) that were included in the SeismicWalkdown Equipment List (SWEL).

F.2.2 PEER REVIEW ACTIVITY - SELECTION OF SSCs

The guidance in Section 3 of the EPRI Seismic Walkdown Guidance (Reference 1) wasused as the basis for this review.

This peer review of SWEL 1 was based on reviews of preliminary documents providedby the SWEL preparer, Mr. Benjamin Frazier. Additionally, the Peer Reviewers,Mr. Butler and Mr. Swanner, interviewed Mr. Frazier. Reference 1 Appendix F:"Checklist for Peer Review of SSC Selection," was used by the Peer Reviewers to guidetheir review.

For SWEL 1 development, the following actions were completed in the peer reviewprocess:

* Verification that the SSCs selected represented a diverse sample of the,equipment required to perform the following five safety functions:

o Reactor Reactivity Control

o Reactor Coolant Pressure Control

o Reactor Coolant Inventory Control

o Decay Heat Removal

o Containment Function

This peer review determined that the SSCs selected for the seismic walkdownsrepresent a diverse sample of equipment required to perform the five safety functions.

* Verification that the SSCs selected include an appropriate representation ofitems having the following sample selection attributes:

o Various types of systems

o Major new and replacement equipment (there are none)

o Various types of equipment

o Various environments

o Equipment enhanced based on the findings of the IPEEE (or USI A-46)

o Risk insight consideration


This peer review determined that the SSCs selected for the seismic walkdowns includean appropriate sample of items that represent each attribute/consideration identifiedabove. The justification for this conclusion is: a) Based on a review of the UFSAR andSWEL 1 list, it was determined that an appropriate variety of equipment and systems arerepresented (e.g., HPCI, RCIC, Core Spray, RHR, CRD Scram Hydraulic, High PressureService Water, Batteries); b) The SWEL identifies that there are no "New andReplacement" equipment; c) A variety of location environments are included (e.g., DieselRooms, Reactor Building, Drywell, Turbine Building, Screen House, Pump Structure); d)The SWEL identifies several items of equipment that were enhanced as a result ofIPEEE; and e) Risk Significant equipment items are identified on the SWEL. Additionaldetails for these conclusions are presented in Attachment 1: Peer Review Checklist forSWEL.

There are no SWEL 2 items for PBAPS Unit 3. To confirm the appropriateness of thisconclusion, the following actions were completed in the peer review process:

Verification that spent fuel pool (SFP) related Seismic Class I SSCs wereconsidered and appropriate justification was documented for why these itemswere not added to the SWEL 2.

This peer review determined that there are no spent fuel pool related items that areSeismic Class I.

Verification that the potential for rapid drain down of the SFP was consideredin accordance with the Reference 1 guidance, and appropriate justificationwas documented for no items being added to SWEL 2.

This peer review determined that appropriate consideration and justification wereprovided for there being no items identified that could result in rapid drain down. Thereare no SFP penetrations that could result in rapid draindown, and Fuel Pool Cooling andCleanup piping includes holes specifically intended to prevent siphoning and draindownof the spent fuel pool (See Section 4.3 of the Report as well as Attachment 1 to thisAppendix).

F.2.3 PEER REVIEW FINDINGS - SELECTION OF SSCs

This peer review found that the process for selecting SSCs that were added to theSWEL was consistent with the process outlined in Section 3 of Reference 1.

The Peer Review Checklist is attached to this document with additional observationsdocumented as appropriate. There were no comments or observations on the SWEL.This peer review resulted in no findings.

F.2.4 RESOLUTION OF PEER REVIEW COMMENTS - SELECTION OF SSCS

All comments requiring resolution were incorporated prior to completion of this peerreview.


F.2.5 CONCLUSION OF PEER REVIEW - SELECTION OF SSCs

This peer review concludes that the process for selecting SSCs to be included on theseismic walkdown equipment list appropriately followed the process outlined inReference 1, Section 3: Selection of SSCs. It is further concluded that the SWELsufficiently represents a broad population of plant Seismic Class I equipment andsystems to meet the objectives of the NRC 50.54(f) Letter.

F.3Review of Sample Checklist & Area Walk-Bys

The on-site and follow-up peer reviews of the seismic walkdowns were performed forPBAPS Unit 3 by Mr. Patrick Butler, Ms. Caroline Schlaseman and Mr. Craig Swanner.The Peer Review Team reviewed Seismic Walkdown Checklists (SWC) and Area Walk-by Checklists (AWC) that were performed for Peach Bottom Unit 3 and Commonequipment, and interviewed the walkdown team members regarding details in checklists.

For Unit 3, there were two walkdown teams, which each consisted of two SeismicWalkdown Engineers (SWEs). The first team consisted of Mr. Benjamin Frazier and Mr.Mojtaba Oghbaei. The second team consisted of Mr. James Wiggin and Mr. KevinGantz. During the second week of walkdowns, Mr. Craig SwannerI replacedMr. Oghbaei.

F.4Review of Licensing Basis Evaluations

There were no instances identified during the walkdowns where evaluated componentscould not readily be shown to meet the plant seismic licensing basis. Accordingly, nolicensing basis evaluations to determine if equipment complied with current seismiclicensing basis requirements were required. However, there were some anomalies orconditions adverse to quality identified during the walkdowns. Tables 5-2 and 5-3 in themain body of the report provide a list of the anomalies encountered during the Unit 3seismic walkdown inspections and how they were addressed.

Attachment 1: Peer Review Checklist for SWEL

Peer Review Checklist for SWEL - Peach Bottom Atomic Power Station Unit 3


This peer review checklist may be used to document the review of the Seismic WalkdownEquipment List (SWEL) in accordance with Section 6: Peer Review. The space below each questionin this checklist should be used to describe any findings identified during the peer review processand how the SWEL may have changed to address those findings. Additional space is provided at theend of this checklist for documenting other comments.

1. Were the five safety functions adequately represented in the SWEL 1 selection? YE NEiAll five safety functions were included in the SWEL Selection.

2. Does SWEL 1 include an appropriate representation of items having the following sampleselection attributes:

a. Various types of systems? YO NEA wide variety of systems were represented including Residual Heat Removal,Reactor Core Isolation Cooling, Core Spray, High Pressure Coolant Injection,Control Drive Hydraulic, High Pressure Service Water, 125 VDC, 120 VAC, 480VA C.

b. Major new and replacement equipment? YE N[lDue to the significant number of modifications performed in the late 1990's as partof the USI A-46 (SQUG) and IPEEE programs, PBAPS Unit 3 has not madesignificant modifications to Seismic Class I equipment within the last several years.Accordingly, SWEL I does not identify any new or replacement components.

c. Various types of equipment? YE NE]All of the EPRI equipment classes are represented with the exception of Classes#11 Chillers, #12 Air Compressors, and #13 Motor Generators. No Seismic Class Iequipment in these three classes were identified at PBAPS Unit 3.

d. Various environments? YED NREquipment in various environments including the Reactor Building, ControlStructure, Screen House, Pump Structure, Turbine Building, Diesel GeneratorBuilding and Drywell are included.

e. Equipment enhanced based on the findings of the IPEEE (or equivalent) YE NEIprogram?The Unit 3 SWEL includes a sample of equipment items that were enhanced basedon findings of the USI A-46 (SQUG) and IPEEE programs (see Sections 4.2 and 7of the Report).

f. Were risk insights considered in the development of SWEL 1? YE NEIThe plant Probabilistic Risk Assessment (PRA) was reviewed and used to guideselection of the components on SWEL 1. Specifically, the relative risk significanceof candidate components including the Risk Achievement Worth (RAW) andFussell-Vesely importance for a Loss of Off-Site Power (LOOP) scenario from theinternal plant PRA were used (See Section 4.2 of the report).

3. For SWEL 2:

a. Were spent fuel pool related items considered, and if applicable included in Y[Z NEISWEL 2?Both parts of SWEL 2, assessment of Seismic Class I spent fuel pool (SFP) relatedequipment and equipment that could potentially result in rapid drain-down of theSFP were considered. There is no equipment in either category. Seedocumentation of SFP item review in Section 4.3 of the Report.

b. Was an appropriate justification documented for spent fuel pool related items YZ NEInot included in SWEL 2?As noted in Section 4.3 of the report, there is no Seismic Class I spent fuel poolrelated equipment.

Section 4.3 also includes appropriate justification that there are no items ofequipment that could cause rapid drain-down due to lack of penetrations withinabout 10 feet above the top of the fuel racks, and there are adequate anti-syphonfeatures included in piping that terminate within a few feet of the tops of the fuelracks.

4. Provide any other comments related to the peer review of the SWELs.

The Peer Review team had no comments on the SWEL.

5. Have all peer review comments been adequately addressed in the final SWEL? YO NEI
