Plan for Future Seismic Walkdown of Inaccessible Equipment Sixteen (16) items could not be walked down during the 180-day period following the issuance of the 1 OCFR50.54(f) letter due to their being inaccessible. 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 Oyster Creek 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.

Associates (S&A) for Unit 1 of the Oyster Creek Generating Station (OCGS). 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).
Observation of the seismic walkdowns on August 23, 2012 and adherence to the Seismic Walkdown Guidance (SWG)1 by Mr. Todd Bacon.
Review of a sample of the checklists prepared for the Seismic Walkdowns & Walk-Bys.
Review of licensing basis evaluations, as applicable.
Review of the decisions for entering the potentially adverse conditions into the plant's Corrective Action Plan (CAP).
Review of the final submittal report The peer reviewers for OCGS, Unit 1 are Messrs. Walter Djordjevic, Todd A. Bacon, and Tony Perez, all of S&A. Mr. Djordjevic is designated the Peer Review Team Leader.
None of the aforementioned engineers is involved in the seismic walkdown inspection process so that they can maintain their independence from the project. Mr. Djordjevic is an advanced degree structural engineer, 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). Mr. Bacon is a civil-structural engineer with over thirty years of nuclear engineering experience and has received the Seismic Walkdown Engineer (SWE) training. Mr. Perez is a mechanical engineer with 15 years of experience and a trainee in a 9 month Senior Reactor Operator Certificate training program. Mr. Djordjevic, as Peer 1 EPRI Technical Report 1025286, Seismic Walkdown Guidance for Resolution of Fukushima Near-Term Task Force Recommendation 2.3: Seismic, dated June 2012.

12Q0108.80-R-001, Rev. 1 Correspondence No.: RS-12-177 Review Team Leader, has participated in all phases of the peer review process for OCGS Unit 1.
The SWEL development was performed by Mr. T. K. Ram of S&A. No findings were cited on the peer review checklist. The completed SWEL Peer Review Checklist is found in Attachment 1. The discussion for the SWEL development peer review is found in Section 2.
The peer review of the seismic walkdown inspection started on August 23, 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. Mark Etre of the SWE inspection team on October 1, 2012 and Mr. Seth Baker of the SWE walkdown inspection team on October 2, 2012. The discussion of the sample SWCs and AWCs is provided in Section 3.
No issues were identified which challenged the current licensing basis.

12Q0108.80-R-001, Rev. 1 Correspondence No.: RS-12-177 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 Oyster Creek Generating 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 2, dated 08/10/2012 This peer review was based on interviews with the following individual who was directly responsible for development of the SWEL:
- Mr. Tribhawan (TK) Ram, 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:

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. There were items identified as potentially related to rapid drain down and these items were added to SWEL 2 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 with additional findings documented as appropriate.
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.

Tables 5-2 and 5-3 of the Seismic Walkdown Report (final submittal report) provide the lists of the issues identified for the equipment seismic walkdowns and area walk-bys.
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 was one instance found throughout the plant concerning ladder storage adjacent to a tank. It can be concluded that OCGS, Unit 1 implements their seismic housekeeping program consistently and to a high standard.
Items identified during the Seismic Walkdowns and Area Walk-bys were ultimately not judged to be "Potentially Adverse Seismic Conditions", as summarized in Sections 5.2 and 5.3 of the Seismic Walkdown Report. There were minor instances of loose hardware (bolts/nuts) and a few bent hanger rods. There was an instance of an open s-hook on a light fixture. In all instances issues identified were judged that they would not prevent the equipment from performing its safety-related function.
The Seismic Walkdown Checklists document the details of all issues identified, the action taken and the conclusion rendered by the SWE inspectors.
The peer reviewers consider the judgments made by the SWEs to be appropriate and in concurrence with the SWG.
