Public Service of Indiana AITN:
Mr. S. W. Shields Vice President - Electric Systems 1000 East Main Street Plainfield, IN 46168 Gentlemen:
This refers to the meetings held at the Marble Hill construction site on June 29, and July 7, 1979, between Mr. R. M. Brown and representatives of Public Service of Indiana, Newberg-Marble Hill and Sargent and Lundy Engineers and D. W. Hayes, C. C. Williams and others of my staff. This also refers to the meeting held in the Region III office on July 10, 1979, betweer you and I and members of my staff. The purpose of the meetings was to discuss the status of:
(1) the upgraded program for the control of concrete activities, (2) your " overview" program for concrete activities, and (3) your examination and testing program to confirm existing concrete quality.
Based on our review of your upgrsded program and its implementation in connection with portions of the Rad-Waste building and the Unit 2 Turbine building, we have concluded that the conditions outlined in Items 3 and 4 of our Imediate Action Letter (IAL) dated June 27, 1979, have been met.
As discussed in the July 7, 1979, meeting, placement of concrete for safety related structures may resume with the following understanding:
1.
The PSI " overview" program for concrete work will be fully implemented as discussed with you and as outlined in your letter to us dated July 3, 1979.
2.
The examination and testing program discussed in Item 1 of the IAL will be completed expeditiously.
3.
Identified deficiencies will be evaluated in terms of their impact on the current concrete placement program.

No concrete will be placed or other work performed that will coverup or otherwise prevent acce'ss to previously placed concrete relative to the surface and volumetric examination program.
In regard to the PSI " overview" program it is our understanding that all PSI " hold points" discussed in the Newberg-Marble Hill letter to P3I dated June 28, 1979, will apply until adequate confidence thatluture concrete activities will continue to meet requirements is established to the satisfaction of PSI and the NRC. Further, PSI quality control personnel will inspect all Category I concrete placement areas to verify requirements have been met. The PSI inspections are to be conducted af ter Newberg QC has accepted the area, but prior to placement of concrete. PSI QC personnel are also to be present full-time at all Category I pours to verify adequate contractor QC involvement and to assure proper placement and consolidation of the concrete.
Concerning Items 1 and 2 of our IAL involving the testing and evaluation or existing concrete we have concluded that:
1.
Our initial review of your identification and evaluation of concrete repairs indicates it is not yet sufficiently comprehensive.
2.
The adequacy of the preparation of concrete defective areas (honeycomb) for repair and the procedure and material in making some of the repairs continue to remain unresolved at this time.
3.
Your program for acquiring and evaluating tes ; data has not been fully developed and approved.
As discussed with you during our meeting on July 10, 1979, we understand that additional and comprehensive efforts will be made to assure all repaired areas are identified, that all material will be removed from the repaired areas and the repairs be redene. We note that some repairs were made with adeqsate QC coverage and are mot in question. Verification of the adequacy of these repairs will be made on an individual basis with both PSI and the NRC concurring in the resolution. Further, the NRC is to be notified in advance of the removal of material and rerepair so we may elect to witness the activity.
It is not intended that repairs made for cosmetics, such as tie holes be redone.
It is also our understanding that your activities for acquiring and evaluating test data relative to existing concrete is to be fully documented and controlled in accordance with your QA program with each major responsi-bility relative to the involved organizations being identified.
