Dear Mr . Grier:

This is in response to your letter of May 9, 1980, which forwarded IE Bulletin 80-11, "Masonr y Wall Design" . Our letter dated July 2, 1980, contained responses to items 1, 2a , and 3 of the Bulletin and our letter dated November 3, 1980, contained an interim response to item 2b of the Bulletin.

! Attached is our complete report on the re-evaluation of I

concrete mesonry walls at Peach Bottom Atomic Power Station as I

required by the Bulletin. This report includes the information submitted in our first two responses with modifications made

where appropriate.

Fo ur walls were identified during this re-evaluation which did not fully meet the requirements of the re-evaluation l

criteria. Recommended modifications have been completed on the two walls asociated with Unit 2 and will be completed on the Unit 3 walls during the current refueling outage.
