MSA SCBA breathing packs on wall-mounted rack with lip to prevent sliding.
Packs not strapped to rack. Per MA-QC-716-026-1001 (Seismic Housekeeping), the critical aspect ratio (height to least width) is 2.5 to I for overturning when the object is located on a fixed item. The shelf is considered a fixed item based on the mounting of the shelf to the structure. These cases have an aspect ratio less that 2.5 to 1, therefore overturning is not of concern.

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 1 OCFR50.54(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.

Quad Cities Generating Station Unit 2 12Q0108.40-R-002, 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 2 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, IRs 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 2 12Q0108.40-R-002, Rev. 3 Correspondence No.: RS-12-169 4Review of Assessment of Identified Issues Tables 5-2 and 5-3 provide a list of the issues encountered during the Unit 2 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.
