fAe 02-41P Purpose The lateral stiffnesses of the vertical support (two structural angles) attached to the operator of Air-Operated Valve AO-0-33-0241 D and the pipe support (square structural tubing) attached downstream of the valve at the pipe elbow are calculated. The lateral stiffnesses of the supports are compared to help judge whether the valve being supported at two different locations (the diesel room wall and the top of the diesel engine base frame) could potentially cause damage to the valve during a seismic event.

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

E Plan for Walkdown of Inaccessible Equipment and Assessment of Electrical Cabinet Internal Inspections E.1.

PLAN FOR WALKDOWN OF INACCESSIBLE EQUIPMENT As shown in the SWEL for PBAPS Unit 2 in Appendix B (Table B-3), one item has been deferred until a future electrical outage. Table E-1 describes the deferred item and the reason it is inaccessible during normal plant operation. PBAPS Issue Report (IR)

01426027 has been written to schedule the Seismic Walkdown (and Area Walk-By) for this item in the third quarter of 2013.

Table E-1. Summary of Inaccessible Equipment Reason for Component ID Description Inaccessibility 00B094 480V Bus E13A4 Requires 4KV Bus Outage E.2.

ASSESSMENT OF ELECTRICAL CABINET INTERNAL INSPECTIONS All electrical cabinets on the SWEL require assessment of the need for inspections to address the potential for "other adverse seismic conditions" internal to the cabinet. This assessment is required due to an NRC clarification of their expectations for seismic walkdowns, which was received after the online seismic walkdowns were completed.

Tables E-2 (for Unit 2) and E-3 (for Unit 0) list all electrical items that require assessment. Accessibility of equipment, basis for accessibility determination, completion date of internal inspections, tracking number (if internal inspection has not yet been performed) and inspection results are provided in these tables.

F.1 Introduction F.1.1 OVERVIEW This report documents the independent peer review for the Near Term Task Force (NTTF) Recommendation 2.3 Seismic Walkdowns performed by MPR Associates, Inc.

for Unit 2 of Peach Bottom Atomic Power Station (PBAPS). The peer review addresses the following activities:

Review of the selection of the structures, systems, and components, (SSCs) that are included in the Seismic Walkdown Equipment List (SWEL),

Review of a sample of the checklists prepared for the Seismic Walkdowns &

Walk-Bys, Review of any licensing basis evaluations, Review of the decisions for entering the potentially adverse conditions in to the plant's Corrective Action Program (CAP), and Review of the final submittal report.

F.1.2 PEER REVIEWERS The Peer Reviewers are Patrick Butler, Caroline Schlaseman and Craig Swanner.

Mr. Butler is the Peer Review Team Leader, per the EPRI Seismic Walkdown Guidance (Reference 1). As Peer Review Team Leader, he was responsible for the entire peer review process, including completion of the final peer review documentation in this report.

Peach Bottom Atomic Power Station Unit 2 F-4 MPR-3815, Revision 3 Correspondence No.: RS-12-173

Mr. Swanner is a degreed aerospace engineer with 20 years of nuclear plant experience. Mr. Swanner has been trained as a Seismic Capability Engineer and 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 review of the SWEL development was performed by Mr. Butler and Mr. Swanner, and was conducted between August 2, 2012 and August 16, 2012. There were no comments as noted on the SWEL Peer Review Checklist and no findings were cited. The completed SWEL Peer Review Checklist is found in Attachment 1. The discussion for the SWEL development peer review is provided in Section 2. Note that due to equipment accessibility including ALARA and electrical safety concerns, changes to the SWEL were made as the walkdowns were conducted. The Peer Review Team did review changes made during the walkdown and has reviewed the final SWEL included in Appendix B of the Walkdown Report. As noted in the SWEL Peer Review Checklist, there were no items from EPRI Equipment Classes 11, Chillers; 12, Air Compressors; or 13, Motor Generators. This was because there is no safety-related Seismic Class I equipment in these classes at Peach Bottom Unit 2. There is no Class 2, Low Voltage Switchgear (LVS) equipment in the Unit 2 SWEL, but there is one Class 2 LVS in the Unit 0 (common) SWEL, which has been deferred. Also, due to the significant number of modifications performed in the late 1990's as part of the USI A-46 (SQUG) and IPEEE programs, PBAPS Unit 2 has not made significant modifications to Seismic Class I equipment within the last several years.

F.A.4 SEISMIC WALKDOWN The on-site peer review of the seismic walkdowns was performed by Mr. Butler and Ms. Schlaseman on August 30, 2012. The on-site and follow-up reviews included approximately 31% of the SWCs and approximately 43% of the AWCs applicable to the equipment for Unit 2 and common, including checklists, photos, and drawings where applicable. Interviews were conducted with both teams of SWEs to assess conduct of the walkdowns and adherence to the EPRI Seismic Walkdown Guidance (Reference 1).

The discussion of the review of the sample of Seismic Walkdown Checklists (SWCs) and Area Walk-By Checklists (AWCs) is provided in Section 3.

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

F.2 Peer Review - Selection of SSCs F.2.1 PURPOSE The purpose of this section is to describe the process to perform the peer review of the selected structures, systems, and components, (SSCs) that were included in the Seismic Walkdown 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) was used as the basis for this review.

This peer review of SWEL 1 was based on reviews of preliminary documents provided by 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 guide their review.

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

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

o Reactor Reactivity Control 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 walkdowns represent a diverse sample of equipment required to perform the five safety functions.

Verification that the SSCs selected include an appropriate representation of items 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 Peach Bottom Atomic Power Station Unit 2 F-6 MPR-3815, Revision 3 Correspondence No.: RS-12-173

This peer review determined that the SSCs selected for the seismic walkdowns include an appropriate sample of items that represent each attribute/consideration identified above. The justification for this conclusion is: a) Based on a review of the UFSAR and SWEL 1 list, it was determined that an appropriate variety of equipment and systems are represented (e.g., HPCI, RCIC, Core Spray, RHR, CRD Scram Hydraulic, High Pressure Service Water, Batteries); b) The SWEL identifies that there are no "New and Replacement" equipment; c) A variety of location environments are included (e.g., Diesel Rooms, Reactor Building, Drywell, Turbine Building, Screen House, Pump Structure); d)

The SWEL identifies several items of equipment that were enhanced as a result of IPEEE; and e) Risk Significant equipment items are identified on the SWEL. Additional details for these conclusions are presented in Attachment 1: Peer Review Checklist for SWEL.

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

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

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

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

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

F.2.3 PEER REVIEW FINDINGS - SELECTION OF SSCs This peer review found that the process for selecting SSCs that were added to the SWEL was consistent with the process outlined in Section 3 of Reference 1.

The Peer Review Checklist is attached to this docurnent with additional observations documented 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 peer review.

2.5 CONCLUSION

OF PEER REVIEW - SELECTION OF SSCs 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, Section 3: Selection of SSCs. It is further concluded that the SWEL sufficiently represents a broad population of plant Seismic Class I equipment and systems to meet the objectives of the NRC 50.54(f) Letter.

F.4 Review of Licensing Basis Evaluations There were no instances identified during the walkdowns where evaluated components could not readily be shown to meet the plant seismic licensing basis. Accordingly, no licensing basis evaluations to determine if equipment complied with current seismic licensing basis requirements were required. However, there were some anomalies or conditions adverse to quality that were identified during the walkdowns. Tables 5-2 and 5-3 in the main body of the report provide a list of the anomalies encountered during the Unit 2 seismic walkdown inspections and how they were addressed.

b. Was an appropriate justification documented for spent fuel pool related items not included in SWEL 2?

As noted in Section 4.3 of the report, there is no Seismic Class I spent fuel pool related equipment.

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