Enclosed are three (3) signed originals and thirty-seven (37) copies of Revision 4 to the Report on the Reanalysis of Safety Related Piping Systems for Beaver Valley No. 1 Unit.
This revision consists of replacement pages to the original report submitted to you on June 19, 1979 and includes information on the results of the analysis on certain supports that had previously not been analyzed. We have determined that one additional modification is required.
This modification consists of the removal of one support to permit the remaining existing supports to better accomodate the design loads.
We have now completed all modification work identified in the amended report and hereby request that the Nuclear Regulatory Commission terminate the March 13, 1979 Order to Show Cause.
