Is anchorage configuration verification required (i.e., is the item one of the 50%

Yes of SWEL items requiring such verification)?

2.

Is the anchorage free of bent, broken, missing or loose hardware?

Yes

3.

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

Yes

4.

Is the anchorage free of visible cracks in the concrete near the anchors?

Yes Tank has hair line crack at 10 of 16 anchor bolts. The cracks do not extend into base slab and are only in the approximately.1' high pad. Anchor is embedded in base slab greater than 1' in depth and pad is reinforced in area of cracks so cracks will not propagate. Cracks will not impact anchor strength and are not a structural/seismic issue. IR 1396566 was generated to document issue.

5.

Is the anchorage configuration consistent with plant documentation? (Note:

Yes This question only applies if the item is one of the 50% for which an anchorage configuration verification is required.)

Scaffold/robust barrier is built around rack 2PL84JB. Portions of scaffold are very near to instrument air lines and other components of rack. Discussed with scaffolding personnel who proceeded to modify scaffold to provide more clearance and complete stand-offs so scaffold/robust barrier cannot move into rack.
