Instructions for Completing Checklist This checklist may be used to document the results of the Seismic Walkdown of an item of equipment on the SWEL. The space below each of the following questions may be used to record the results of judgments and findings.

Additional space is provided at the end of this checklist for documenting other comments.Anchorage 1. Is anchorage configuration verification required (i.e., is the item one of the 50%of SWEL items requiring such verification)?

No 2. Is the anchorage free of bent, broken, missing or loose hardware?Not Applicable

3. Is the anchorage free of corrosion that is more than mild surface oxidation?
4. Is the anchorage free of visible cracks in the concrete near the anchors?5. Is the anchorage configuration consistent with plant documentation? (Note: This question only applies if the item is one of the 50% for which an anchorage configuration verification is required.)

Not Applicable Not Applicable Not Applicable

6. Based on the above anchorage evaluations, is the anchorage free of potentially adverse seismic conditions?

The insertion accumulator is an in-line component that is adequately restrained to the CRD/HCU support frame.Yes C-119 Dresden Generating Station Unit 3 12QO108.30-R-002, Rev. 2 Correspondence No.: RS-12-167 Sheet 2 of 2 Status: FY7 N U Seismic Walkdown Checklist (SWC)Equipment ID No.: D03-0305-0058-0023-0125-A10 Equipment Class: (21) Tanks and Heat Exchangers Equipment

All panel doors opened. No other adverse seismic conditions.

IR 1394831: Panel with doors that do not latch While performing NRC-required NTTF seismic walkdowns, Panel 903-28 was found unlocked and unlatched.

The opening device is a push button lock without a handle, which makes it impossible to engage the latches without a key. Upon discovery, Operations was dispatched to find a key, but they were unsuccessful in finding one.As an interim measure, the doors have been secured (taped shut) to prevent movement during a seismic event. In addition, a satisfactory "tug test" on the secured doors was performed by two SQUG-qualified engineers.

This interim solution is judged to be acceptable and has been accepted by Operations (Shift Manager).C-148 Dresden Generating Station Unit 3 12Q0108.30-R-002, Rev. 2 Correspondence No.: RS-12-167 Sheet 3 of 5 Status: Y-7 N U Seismic Walkdown Checklist (SWC)Equipment ID No.: Equipment Class: Eauipment
