Additional space is provided at the end of this checklist for documenting other comments.Anchorage l. Is the anchorage configuration verification required (i.e., is the item one of the 50%o of SWEL items requiring such verification)? Long heat exchanger on two saddles hungfrom the ceiling. Fixed support qt ceiling is anchoredwith 28-1 I/2" diam anchor bolts. Sliding end is anchoredwith 24-l I/2" diam amchors.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?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 50Yo forwhich an anchorage configuration verification is required.)Anchorage configuration confirmed per Drawings RV-0076A and RV-00768 6.

Is the anchorage configuration verification required (i.e., is the item oneof the 50o/o of SWEL items requiring such verification)?Anchoredwith 14-1 l/4" diam anchor bolts. 6 of l4 anchors are below the engine block and there is a gap of -l/2" betweenfloor and base of DG skid. Other anchors have grout pads. It is judged that the skid has adequate capacityfor the demand loads.Also it is judged that bolt bending is not a concern due to gap of -l I/2". (see alsocalculation 5 2 2 3 3-C-0 I 8)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?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.)Calculation 52233-C-018, page 4/17 confirms the anchorage configurotion.

6. Based on the above anchorage evaluations, is the anchorage free of potentially adverse seismic conditions?The support beams for the EDG skids were identified not to be groutedfor their entirelength. SQUG and design basis documentation provides justificationfor thisfinding.

The space below each of the following questions may be used to record the results ofjudgments and findings. Additional space is provided at the end of this checklist for documenting other comments.Anchoragel. Is the anchorage configuration verification required (i.e., is the item oneof the 50o/o of SWEL items requiring such verification)?The switchboard is attached to three sill channels at base with six l/2" diameter bolts.The sill channels are anchored to concrete floor with six I/2" diameter anchor bolts (2 atfront, 2 at middle and 2 at back). Component identified not to be attached to adjacent DC Battery SWGR No.3 panel. No essential relays identified therefore judged not a concern. DC Battery SWGR No.3 Panel identified to be anchoredwith 2-1/2" diam anchors atfront and l-l/2" diam anchor at back ofpanel. Typicalc onfiguration for all SWB D's.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?

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 50o/o forwhich an anchorage configuration verification is required.)Both SEWS and calc. 52233-C-014 identify four attachment points.for this switchboard. The referenced calculation conservatively shows anchor bolt adequacy based onfour bolt pattern.6. Based on the above anchorage evaluations, is the anchorage free of potentially adverse seismic conditions?

Additional space is provided at the end of this checklist for documenting other comments.Anchoragel. Is the anchorage configuration verification required (i.e., is the item oneof the 50% of SWEL items requiring such verification)?MCC composed of 5 sections. MCC base channel is welded to embed steel with an average of -5" of I/4" weld at front of each MCC section. The weld on the back cannot be verified since MCC is too close to wall. Typically MCCs that are too closeto awall have their rear mounting channels welded to embed steel by welding thechannelflange that is inside the MCC (as opposed to theflange outside of the I,ICC and closer to the wall). For this MCC the base of the unit could not be accessed and presense o the backwelds was not verified.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?4. Is the anchorage free of visible cracks in the concrete near the anchors?
