Engelken, Director U.

Dear Mr. Engelken:
Supplement No. 4 to LER 79-15, which contained the pro-posed criteria to be used in the analysis of the out-of-plane behavior of heavyweight double wythe masonry walls, was submitted to you by my letter dated June 10, 1980.
In meetings held on June 19-20 and June 25-28 with the NRC Staff agreement was reached on revised criteria, which have been expanded in scope to include all casonry walls having safety significance.
The enclosed attachments and tables reflect the agreed-upon revisions to the criteria.
As also agreed to at the meetings, all masonry walls in the Plant will be evaluated in accordance with the revised criteria, except that the allowable collar joint shear stress for standard weight and heavyweight double wythe walls in areas which are accessible during Plant operation shall be 24 psi and 12 psi, respectively.
Based on the results of these evaluations the following actions will be taken prior to resumption of power operation for walls having safety significance which do not satisfy the criteria:
1)
For multiple wythe walls for which the interface stress criteria are exceeded, wall delamination will be assumed and a determination will be made as to whether the assumed delamination would adversely impact the function of safety-related systems, attached to the wall or in its area of influence (2 feet) in accordance with "3)" below.
' "- - '-* ed systems would be adversely
-~
ill be modified.
