Enclosed are three (3) signed originals and thirty-seven (37) copics of Revision 2 to the " Report on the Reanalysis of Safety Related Piping Systems for Ecaver Valley No. 1 Unit". This revision consists of replacement pages to the original rcport submitted to you on June 19, 1979 and includes responses to certain questions received from the staff in a telephone conversation on July 13, 1979. The changes included herein resolve four (4) minor inconsistencies fc,und in the report.

It is our understanding that upon receipt of this revision to the report, all of the staff's concerns with respect to the reanalysis effort will be satisfied, and we, therefore, request that so much of the Commission's March 13, 1979 Order which requires the plant to remain in a shutdown condition be modified at this time to permit interim operation of the unit until the time for refueling.

Very truly yours,
