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?3. Is the anchorage free of corrosion that is more than mild surface oxidation?

W PROCESS ANALOG PROTECTION SET CAB-04 Interaction Effects 7. Are soft targets free from impact by nearby equipment or structures?
SWT noted cable tray with 1/4" vertical clearance to top of cabinet support modification.
Concern is that differential movement between the floors can cause equipment to spatially interact and cause change of state in SB041.Both pieces can be taken as rigid in the vertical direction.
Verify from In-Structure Response Spectra whether clearance is acceptable.
Licensing Basis Evaluation:
Inspection of vertical response spectra at this level confirms that 1/4" is more than adequate separation for vertically rigid components.
No adverse seismic concern.8. Are overhead equipment, distribution systems, ceiling tiles and lighting, and masonry block walls not likely to collapse onto the equipment?
- 9. Do attached lines have adequate flexibility to avoid damage?10. Based on the above seismic interaction evaluations, is equipment free of potentially adverse seismic interaction effects?Yes Yes Yes Yes Other Adverse Conditions
- 11. Have you looked for and found no adverse seismic conditions that could Yes adversely affect the safety functions of the equipment?
Cabinets RPO 18, SB041, and SB042 are bolted at their tops. This appears to be a modification not included in original equipment qualifications.
Verify whether modification documents the qualification reconciliation of individual equipment.
Licensing Basis Evaluation:
Condition is analyzed per WCNOC Calc XX-FH-009-002. No adverse seismic concern.Comments WCAP-17678-NP November 2012 Revision 0 A-354 Status: i- N U Seismic Walkdown Checklist (SWC)Equipment ID No.: SB041 Equipment Class: (20) Instrumentation and Control Panels and Cabinets Equipment

SWT noted tubing/piping support mounted off of AHU that does not appear to be included in original equipment qualification (possibly from later modification).
Verify whether modification is documented and AHU equipment qualification reconciliation was addressed.
Licensing Basis Evaluation:
SWT inspected WCNOC DCP #09879, which states that the connecting equipment between the more recently installed condenser and the AHU does not invalidate the individual equipment seismic qualifications and that the qualification of the AHU remains valid. Therefore, no adverse seismic concern.Comments WCAP-17678-NP November 2012 Revision 0 A-388 Status: Y N U Seismic Walkdown Checklist (SWC)Equipment ID No.: SGK05B Equipment Class: (10) Air Handlers Equipment

SWT observed scaffolding in zone of influence of the tank soft targets (site glass) with no bracing or wall anchorage at top bay (3 bays total). Members appear suitable to withstand moment so as to preclude collapse, but verification is required from scaffolding documentation on site. Also, scaffolding is braced to tank legs. While the tank legs and anchorage appear adequate to withstand relatively light added scaffold lateral load, verification is required to confirm equipment qualification for tank was reconciled.
Licensing Basis Evaluation:
SWT received WCNOC Scaffolding Evaluation (Scaffold Request # 12-SO189, Work Order # 11-345393) that validates scaffold installation in accordance with procedure.
SWT concludes from engineering judgment that scaffolding is acceptable given negligible additional loading due to SSE on rugged tank legs.WCAP-17678-NP November 2012 Revision 0 A-407 Status: N U Seismic Walkdown Checklist (SWC)Equipment ID No.: TEG01B Equipment Class: (21) Tanks and Heat Exchangers Equipment

CLASS 1E LOAD CENTER TRANSFORMER Interaction Effects 7. Are soft targets free from impact by nearby equipment or structures?
Yes XNG02 and NGO02 are visually confirmed to be bolted together.
Therefore there is no equipment chattering concern.The SWT also noted a light fixture in close proximity with a partially open S-hook. Given depth of S-hook and that it is not open enough to allow light to fall under SSE excitation, there is no adverse seismic concern.8. Are overhead equipment, distribution systems, ceiling tiles and lighting, and Yes masonry block walls not likely to collapse onto the equipment?
See Note 7 above. No hazard.9. Do attached lines have adequate flexibility to avoid damage? Yes 10. Based on the above seismic interaction evaluations, is equipment free of Yes potentially adverse seismic interaction effects?Other Adverse Conditions
- 11. Have you looked for and found no adverse seismic conditions that could Yes adversely affect the safety functions of the equipment?
SWT observed bolting from XNG02 to adjacent and flush cabinet NGO02.While it was confirmed that adequate bolting was provided to preclude chatter, one bolt hole was noted to be empty without a bolt. Verify whether bolt is required from configuration documentation.
Licensing Basis Evaluation:
The SWT concluded that the presence of bolting is not required to preclude seismic chatter; therefore no adverse seismic condition.

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)?
Yes 2. Is the anchorage free of bent, broken, missing or loose hardware?Supplier document indicates base channels are with 8 holes for plug welding.Although plug welds are grinded flush and painted SW- confirmed that holes have been filled and plug welds are present.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.)
The supplier document calls for base channels welded to embeds with 8 no.plug welds. Although plug welds are grinded flush and painted, the SWT confirmed that holes have been filled on the vendor supplied base channels;therefore plug welds are present and the anchorage is acceptable.
- 6. Based on the above anchorage evaluations, is the anchorage free of potentially adverse seismic conditions?
