Subject:

Response to Pending Duke Power Concern The comment on page 2 of Reference 2 (forwarded to NRC via Reference 4) correctly noted that no reference wdu made to the honeycomb concrete around one of the watertit;ht dotrs.

An NCR was issued on 7/16/84 identifying the honeycomb around door R-1-8 and was subsequently dispositioned on 7/18/84.

The disposition required chipping out the defective concrete around the door and then performini a QA/ Engineering inspection.

After a successful inspectioni j

the area will be grouted.

In addition to cadre,ctiol of door R-1-8, the NCR disposition requires soundinJ tre concrete around all remaining doors in the Auxiliary Buildincl for volds.

If more voids are found, the NCR requirec\\0.cther reevaluation and corrective action.
