Dear Mr. Stolz:

As described in the Reference (1) transmittal, we have been continuing our efforts on the torus attached piping modifications which completes the Mark I activities for Peach Bottom. All original scope modifications for Units 2 and 3 as described in the Reference (2) meeting have been ccmpleted. The remaining activities for both units are the ccmpletion of the equipment nozzle evaluations and the as-built reconcillation of the modifications. The evaluations and reconciliation' to date have indicated the need for semo additional modifications which are in progress.

Our Plant Unique Analysis Report will be updated to reflect the modifications required on the piping systems attached to the torus.

The final report was tentatively scheduled for June, 1984; however, we now expect this final report to be ready for submittal by December 1985 pending completton of any modifications resultIng from the nozzle evaluations and the as-built reconciliation.

Sincerely, 8506180444 850613 PDR ADOCK 05000277 l
