There is degradation at the joint at the containment.
The joints in question are made up of some sort of compressible/flexible material.
Since the containment structure is a standalone structure and is analyzed and designed that way there is a gap- between it and an adjacent structure (like the MSIV rooms). The gap is sized to allow seismic movements of each structure and is filled with the flexible material.
The material is only there to close the opening and has no structural or seismic significance.

Additional space is provided at the end of this checklist for documenting other comments.Anchoraqge
- 1. Is anchorage configuration verification required (i.e., is the item one of the 50% No 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 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
- 6. Based on the above anchorage evaluations, is the anchorage free of potentially adverse seismic conditions?
See discussion in Section 5 of report to address cove molding at anchorage detail. Anchorage is judged to be acceptable.
