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 Clinton Power 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 clarification 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.

It is noted, that SSCs identified on Table E-1 do not appear on Table E-2.E-1 Clinton Power Station 12Q0108.60-R-001 Rev. 0 Correspondence No.: RS-12-165 Table E-1. Inaccessible and Deferred Equipment List Component Reason for Action Resolution

1. The discussion for the SWEL development peer review is found in Section 2.The peer review of the seismic walkdown inspection started on September 11, 2012 with a peer check of the actual walkdowns for Unit 1. Mr. Bacon joined the walkdown team for a portion of the day's planned walkdowns to observe the conduct of walkdowns and adherence to the SWG. Interviews were conducted by Messrs. Bacon and Djordjevic with the SWE inspection team after review of a sample of the Unit 1 Seismic Walkdown Checklists (SWCs) and the Area Walk-by Checklists (AWCs) to ascertain procedural compliance with the SWG. The interviews were conducted with Mr. Dave Carter of the SWE inspection team on October 8, 2012 and with Mr. Phil Gazda of the SWE inspection team on October 26, 2012. The discussion of the sample SWCs and AWCs is provided in Section 3.No issues were identified which challenged the current licensing basis.Sheet 3 of 11 F-4 Clinton Power Station 12Q0108.60-R-001 Rev. 0 Correspondence No.: RS-12-165 2Peer Review -Selection of SSCs 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).This section documents the Peer Review -Selection of SSCs performed for Clinton Power Station -Unit 1.2.2 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, Section 3: Selection of SSCs was used as the basis for this review.This peer review was based on reviews of the following documents:

• Seismic Walkdown Interim Report, Revision 1, dated 09/18/2012 This peer review was based on interviews with the following individual who was directly responsible for development of the SWEL:* Mr. Tony Perez, Senior Mechanical Engineer This peer review utilized the checklist shown in the SWG, Appendix F: Checklist for Peer Review of SSC Selection.

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 (RRC)o Reactor Coolant Pressure Control (RCPC)o Reactor Coolant Inventory Control (RCIC)o Decay Heat Removal (DHR)o 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.

• 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 o Various types of equipment Sheet 4 of 11 F-5 Clinton Power Station 12Q0108.60-R-001 Rev. 0 Correspondence No.: RS-12-165 o Various environments o Equipment enhanced based on the findings of the IPEEE o 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.For SWEL 2 development, the following actions were completed in the peer review process:* Verification that spent fuel pool related items were considered and appropriately added to SWEL 2.This peer review determined that spent fuel pool related items were given appropriate consideration.

Portions of the spent fuel pool cooling system are classified as Seismic Category 1 (Class I) and SWEL 2 was sufficiently populated as appropriate.

• Verification that appropriate justification was documented for spent fuel pool related items that were not added to the SWEL 2.This peer review determined that an appropriate level of justification was documented for those items related to the spent fuel pool that were not added to SWEL 2.2.3 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 the SWG Section 3: Selection of SSCs.The peer review checklist is attached to this document.

This peer review resulted in no additional findings.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 the SWG, Section 3: Selection of SSCs. It is further concluded that the SWEL sufficiently represents a broad population of plant Seismic Category 1 (Class I) equipment and systems to meet the objectives of the NRC 50.54(f) letter.Sheet 5 of 11 F-6 Clinton Power Station 12Q0108.60-R-001 Rev. 0 Correspondence No.: RS-12-165 31Review of Sample Seismic Walkdown & Area Walk-Bys Checklists 3.1 OVERVIEW A peer review of the SWCs and AWCs was performed on September 11, 2012, after which an interview was conducted by Messrs.

A review of Tables 3-1 and 3-2 of the previous section show no concerns or findings in the sampling of the SWCs and AWCs. Tables 5-2 and 5-3 of the Seismic Walkdown Report (final submittal report)provide the lists of the issues encountered for the equipment seismic walkdowns and area walk-bys.

The single issue for the SWEL equipment was a documentation discrepancy for Cabinet 1 DG01JB for which an IR was written and a missing clamp support for the 1/2" tubing line to a non-seismic transmitter 1 C11N052 for which an IR was written that resulted in a work order.The scaffolding and seismic housekeeping procedures were reviewed by the SWEs in order to gain a full understanding of the plant practices in regard to those procedures.

There were no seismic concerns noted in Unit 1 with regard to scaffold erection.

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

Concerning seismic housekeeping, there were no instances found throughout the plant and it can be concluded that CPS Unit I implements their seismic housekeeping program consistently and to a very high standard.The peer reviewers consider the judgments made by the SWEs to be appropriate and in concurrence with the SWG.Sheet 9 of 11 F-I 0 12Q0108.60-R-001 Rev. 0 Correspondence No.: RS-12-165 4Review of Licensing Basis Assessments Tables 5-2 and 5-3 of the Seismic Walkdown Report provide a list of the issues encountered during the Unit 1 seismic walkdown inspections for the SWEL components and how they were addressed.

If a CPS IR request was generated it is shown in the Tables. Interviews were conducted by Messrs. Djordjevic and Bacon with the SWE inspection team on October 8 and October 26, 2012 to discuss the issues identified.

No potentially adverse seismic conditions were identified that resulted in a seismic licensing basis evaluation.

The peer reviewers concur with this outcome.Sheet 10 of 11 F-11 12Q0108.60-R-001 Rev. 0 Correspondence No.: RS-12-165 51Review Final Submittal Report & Sign-off The entire final submittal report has been reviewed by Messrs.
