Plan for Future Seismic Walkdown of Inaccessible Equipment Ten (10) items could not be walked down during the 180-day period following the issuance of the 10CFR50.54(f) letter due to their being inaccessible. The items will be walked down during a unit outage or another time when the equipment is accessible, as appropriate. Table E-1 summarizes the reason(s) each item is inaccessible during normal plant operation and notes the Quad Cities Station Issue Report (IR) that has been written to schedule the Seismic Walkdowns (and Area Walk-bys) for the item.
In addition, certain cabinets require internal inspection for other adverse seismic conditions as summarized in Table E-2. Supplemental internal inspections of these cabinets are required due to clarification informally provided to the industry after the online seismic walkdowns were completed. These supplemental inspections will be completed during a unit outage or time when the equipment is accessible, as appropriate.

Review of the final submittal report The peer reviewers for QCNS, Unit 1 are Messrs. Walter Djordjevic, Todd A. Bacon, and Tribhawan K. Ram, 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 25 years of nuclear engineering experience and received the Seismic Walkdown Engineer (SWE) training. Mr. Ram is an advanced degree nuclear engineer with over 25 years of nuclear power plant experience. Mr. Djordjevic led the seismic peer review activities and Mr. Ram led the SWEL selection peer review. Mr. Djordjevic, as Peer Review Team Leader, has participated in all phases of the peer review process for Quad Cities, Unit 1.
The SWEL development was performed by Mr. Tony Perez of S&A. There were a few observations noted on the SWEL Peer Review Checklist which were resolved. No findings were cited. The completed SWEL Peer Review Checklist is found in. The discussion for the SWEL development peer review is found in Section 2.

Quad Cities Generating Station Unit 1 12Q0108.40-R-001 Rev. 3 Correspondence No.: RS-12-169 The peer review of the seismic walkdown inspection started on August 7, 2012 with a peer check of the actual walkdowns for Quad Cities, Unit 2. Mr. Djordjevic 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)'. No additional peer review site visits were made for the Unit 1 walkdown as the same procedures were implemented and nearly the same SWEL equipment was inspected. However, an interview was conducted by Messrs. Djordjevic and Bacon with the SWE inspection team on September 7, 2012 after review of a sample of the Unit 1 Seismic Walkdown Checklists (SWCs) and Area Walk-By Checklists (AWCs) to ascertain the procedural compliance with the SWG. The discussion of the sample SWCs and AWCs is provided in Section 3.
No issues were identified which challenged the current licensing basis.

Quad Cities Generating Station Unit 1 12Q0108.40-R-001 Rev. 3 Correspondence No.: RS-12-169 3.3 EVALUATION OF FINDINGS There were no findings that challenged the licensing basis. The plant was found to have some seismic housekeeping and maintenance (concerning loose screws and fasteners) issues. 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 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, 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, it was still dispositioned to an IR. A generic IR (IR No. 01405922) was written addressing instances of seismic housekeeping.
The instances of loose screws and fasteners are seen as simple general maintenance issues and none of them were adjudged a concern from the seismic performance viewpoint. However, I Rs were generated to repair the affected components.
There were instances of partially open s-hooks on light fixtures but they were isolated and not "clustered" around a single fixture.
In most cases they were adjudged not to be immediate seismic interaction hazards to the equipment in their general proximity.
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.
In all instances 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.

Quad Cities Generating Station Unit 1 12Q0108.40-R-001 Rev. 3 Correspondence No.: RS-12-169 41Review of Assessment of Identified Issues Tables 5-2 and 5-3 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 Quad Cities IR request was generated it is shown in the Tables. An interview was conducted by Messrs. Djordjevic and Bacon with the SWE inspection team on September 7, 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.
