The items will be walked down during a unit outage or time when the equipment is accessible, as appropriate.

Table E-1 summarizes the reasons each item is inaccessible during normal plant operation and notes the Dresden Station Issue Report (IR) that has been written to track completion of the Seismic Walkdowns (and Area Walk-bys) for these items. It is noted that SSCs identified on Table E-1 require a complete inspection including, as applicable, internal inspections of electrical cabinets for other adverse seismic conditions, as required.Certain cabinets require supplemental internal inspection for other adverse seismic conditions as summarized in Table E-2. Supplemental internal inspections of these cabinets are required due to clarifications provided by the NRC after the online seismic walkdowns were completed.

These Supplemental inspections will be completed during a unit outage or another time when the equipment is accessible, as appropriate.

1.1 OVERVIEW

This report documents the independent peer review for the Near Term Task Force'(NTTF) Recommendation

2.3 Seismic

Walkdowns performed by Stevenson

&Associates (S&A) for Unit 2 of Dresden Generating Station. 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 Plan (CAP)* Review of the final submittal report 1.2 PEER REVIEWERS The peer reviewers for Dresden Unit 2 are Messrs. Walter Djordjevic, Bruce M. Lory, and Tribhawan K. Ram, all of S&A. Mr. Lory is designated the Peer Review Team Leader. Mr. Djordjevic served as Peer Review Team Leader for SWEL development.

Other than a peer review of "in progress" seismic walkdown inspections, none of the aforementioned engineers were directly involved in the seismic walkdown inspection of equipment so that they could maintain their independence from the project. Mr.Djordjevic is an advanced degree structural engineer and has over thirty years of nuclear seismic experience and has been trained as a Seismic Capability Engineer (EPRI SQUG training), EPRI IPEEE Add-on, Seismic Fragility and Seismic Walkdown Engineer (SWE) training.

Mr. Lory is a mechanical engineer with 33 years of experience, has been trained as a Seismic Capability Engineer (EPRI SQUG training), is instructor of the Fundamentals of Equipment Seismic Qualification training course for EPRI, and is the co-instructor of the Fukushima Seismic Walkdown training course in response to NTTF 2.3. Mr. Ram is an advanced degree nuclear engineer with over 25 years of nuclear power plant experience.

Mr. Lory led the seismic peer, review activities and Mr. Djordjevic led the SWEL selection peer review. Resumes for the peer reviewers are included in Appendix A of the report.1.3 SWEL DEVELOPMENT The SWEL development was performed by Mr. Tony Perez of S&A. The peer review of the SWEL development was concurrent with the SWEL development and any revisions to the SWEL after initial plant acceptance were peer reviewed before approval.

The completed SWEL Peer Review Checklist is found in Attachment

1. The discussion for the SWEL development peer review is found in Section 2.Sheet 2 of 13 F-3 12QO108.30-R-001, Rev. 1 Correspondence No.: RS-12-167 1.4 SEISMIC WALKDOWN INSPECTION The peer review of the seismic walkdown inspection started on July 16, 2012 with a peer check of the actual walkdowns Dresden Unit 2 by Mr. Bruce Lory. Mr. Lory joined the walkdown team for a portion of the day's planned walkdowns to observe the conduct of walkdowns and adherence to the Seismic Walkdown Guidance (SWG)l. An interview was conducted by Messrs. Djordjevic and Lory with the SWE inspection team on September 7, 2012 after review of a sample of the Unit 1 Seismic Walkdown Checklists (SWC) and Area Walk-By Checklists (AWC) to ascertain the quality and procedural compliance with the SWG. The discussion of the sample SWC and AWC is provided in Section 3.Seismic Walkdown Guidance For Resolution of Fukushima Near-Term Task Force Recommendation 2.3: Seismic, EPRI Report 1025286, June 2012.Sheet 3 of 13 F-4 12Q0108.30-R-001, Rev. 1 Correspondence No.: RS-12-167 2Peer Review -Selection of SSCs 2.1 PEER REVIEW ACTIVITY -SELECTION OF SSCS The guidance in EPRI Technical Report 1025286, Seismic Walkdown Guidance for Resolution of Fukushima Near-Term Task Force Recommendation 2.3.- Seismic, dated June 2012 {Reference 1}, Section 3: Selection of SSCs was used as the basis for this review.This peer review was based on reviews of the following documents:

UFSAR chapters 6 and 9* SWEL 1 List* P&IDs M-31 and M-50: Fuel Pool Cooling System This peer review was based on interviews with the following individual(s) who was (were) directly responsible for development of the SWEL:* Tony Perez This peer review utilized the checklist shown in Reference 1 Appendix F: Checklist for Peer Review of SSC Selection.

2.2 UNIT 2 SWEL 1 DEVELOPMENT For SWEL 1 development, the following actions were completed in the peer review process: 1. Verification that the SSCs selected represented a diverse sample of the equipment required to perform the following five safety functions:

A. Reactor Reactivity Control (RRC)B. Reactor Coolant Pressure Control (RCPC)C. Reactor Coolant Inventory Control (RCIC)D. Decay Heat Removal (DHR)E. Containment Function (CF)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.

This conclusion was based on a review of UFSAR chapters 6 and 9, and SWEL 1 which determined that all five safety functions (RRC, RCPC, RCIC, DHR, and CF) are adequately represented.

Sheet 4 of 13 F-5 12Q.108.30-R-;

O1, Rev. 1 Correspondence No.: RS-12-167 2. Verification that the SSCs selected include an appropriate representation of items having the following sample selection attributes:

A. Various types of systems B. Major new and replacement equipment C. Various types of equipment D. Various environments E. Equipment enhanced based on the findings of the IPEEE F. Risk insight consideration This peer review determined that the SSCs selected for the Seismic walkdowns include a sample of items that represent each attribute/consideration identified above. The justification for this conclusion is: a) Based on a review of UFSAR chapters referenced above and the SWEL 1 list, it was determined that appropriate variety.of equipment and systems are represented (e.g., EDG, EDG Fuel Oil Transfer, EDG Cooling Water, LPCI, HPCI, Batteries, Battery Chargers, Low and Med Vol Switchgear and MCCs); b) The "New or Replace" equipment are indicated as such; c) A variety of location environments are included:

e.g., MCCs (TB and RB), Pumps (TB and RB), Tanks and Heat Exchangers (TB and RB), and Valves (RB @ EL 476.5, 517.5, and 570); d) The IPEEE Enhancement related equipement is indicated as such; and e) The risk quantification has been included in the"Comments" column.Note: Because of accessibility reasons, some equipment has appropriately been deferred to Outage.2.3 UNIT 2 SWEL 2 DEVELOPMENT For SWEL 2 development, the following actions were completed in the peer review process: 1. Verification that SFP related items were considered and appropriately added to SWEL 2.This peer review determined that there were no spent fuel pool cooling system Seismic Category 1 items. This determination is based on a review of FSAR chapter 9 and Fuel Pool Cooling System P&lDs M-31 and M-50.2. Verification that appropriate justification was documented for spent fuel pool related items that were not added to SWEL 2.This peer review determined that an appropriate level of justification was documented for having no items on SWEL 2. The justification for not including any Seismic Category I Structure has appropriately been documented in the interim Sheet 5 of 13 F-6 12QO1O8.3O-R-OO1, Rev. 1 Correspondence No.: RS-12-167 report. There are no rapid drain down related components in SWEL 2. Appropriate justification for this item is included in the interim report as well.2.4 PEER REVIEW FINDINGS -SELECTION OF SSCs This peer review found that the process for selection for SWEL 2 SSCs was consistent with the process outlined in Reference 1 Section 3: Selection of SSCs..The peer review checklist for the SWEL is contained in Attachment 1 of this document.This peer review resulted in no additional findings.2.5 RESOLUTION OF PEER REVIEW COMMENTS -SELECTION OF SSCs All comments initiated through the peer review process were minor and were resolved.There are no outstanding issues that require resolution.

2.6 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 Category 1 equipment and systems to meet the objectives of the NRC 50.54(f) Letter.Sheet 6 of 13 F-7 12Q0108.30-R-001, Rev. 1 Correspondence No.: RS-12-167 3 1Review of Sample Seismic Walkdown & Area Walk-Bys Checklists

The scaffolding and seismic housekeeping procedures were reviewed by the SWEs in order to gain a full understanding of the plant practices.

No significant concerns were noted in Unit 2 with Sheet 9 of 13 F-1 0 12Q0108.30-R-001, Rev. 1 Correspondence No.: RS-12-167 regard to scaffold erection.

The scaffolds were properly tied off and braced, and properly tagged with respect to the procedure.

With regard to seismic housekeeping, there were instances found of open S-hooks in the plant. Generally, if they were found to not to contribute to a credible seismic interaction they were adjudged acceptable and not dispositioned to an IR. Similarly, if an item posed a potential proximity hazard to a vital component and it was removed "on the spot" in accordance with the housekeeping procedure, then it was not dispositioned to an IR. However, in all instances the Seismic Walkdown Checklist (SWC) documented the details of the occurrence, the action taken (if any) and the conclusion rendered by the SWE inspectors.

Importantly, if the situation warranted a correction then an IR was specifically generated for that component or area in the case of area walk-bys.The peer review of the SWCs included a recommendation for panels/cabinets which could be opened and inspected for loose or missing component mounting hardware.

It was recommended that a comment be put under question 11 to denote what were the results of the internal inspection.

If no loose or missing mounting hardware was found or if mounting hardware was found loose/missing, a sentence to that affect should be made in the SWC.Sheet 10 of 13 F-11 1200108.30-R-OO1, Rev. 1 Correspondence No.: RS-12-167 4Review of Licensing Basis Assessments
