Dear Mr. Dolan:
DISTRIBUTION NRC PDR Local PDR ORB 1 File D. Eisenhut OELD E. Jordan D. Wigginton C. Parrish J. Taylor ',
ACRS (10)
We have completed our review of the Indiana and Michigan Electric Company (IMEC) responses to IE Bulletin 80-11, Masonry Wall Design, for the Donald C.
Cook Nuclear Plant, Unit Nos.
1 and 2.
Our Safety Evaluation and our contractor Technical'valuation Report are provided in the enclosure.
In our review, we have determined that the IMEC evaluations and modifica-tions of masonry walls at the Donald C.
Cook Nuclear Plant are acceptable except for five walls where IMEC has relied upon joint reinforping in qualifying unreinforced masonry walls.
The structural significance of joint reinforcement in masonry walls is not well established, and therefore, its use as a structural element is not acceptable.
Our staff position on the use of joint reinforcing in qualifying unreinforced masonry walls is also enclosed.
We request that IMEC inform us of actions planned and the schedule for completion of wall modifications in conformance with the wall design criteria (Appendix A to the Technical Evaluation Report).
Your response should be made in accordance with 10 CFR 50.54(f).
We also request that this response be made within 30 days of receipt of this letter.
If you have any questions, please contact the Operating Reactor Project Manager for your plant.

Dear Mr. Dolan:
We have completed our review of the Indiana and Michigan Electric Company
( IMEC) responses to IE Bulletin 80-11, Masonry Wall Design, for the Donald C.
Cook Nuclear Plant, Unit Nos.
1 and 2.
Our Safety Evaluation and our contractor Technical Evaluation Report are provided in the enclosure.
In our review, we have determined that the IMEC evaluations and modifica-tions of masonry walls at the Donald C.
Cook Nuclear Plant are acceptable except for fine walls where IMEC has relied upon joint reinforcing in qualifying unreinforced masonry walls.
The structural signifidance of joint reinforcement in masonry walls is not well established, and therefore, its use as a structural element is not acceptable.
Our staff position on the use of joint reinforcing in qualifying unreinforced masonry walls is also enclosed.
We request that IMEC inform us of actions planned and the schedule for completion of wall modifications in conformance with the wall design criteria (Appendix A to the Technical Evaluation Report).
Your response should be made in accordance with 10 CFR 50.54(f).
We also request that this response be made within 30 days of receipt of this letter.
