Dear Mr. Paulson:

Subject:

Oyster Creek Nuclear Generating Station Docket No. 50-219 SEP Topic No. III-6 Seismic Design Considerations During the integrated assessment of the subject SEP topic, the NRC staff requested GPUN to verify the design adequacy of the piping supports for the two large piping systems analyzed by the NRC (i.e., the main steam and feed water lines).

The attached report presents the results of a seismic reanalysis of Oyster Creek's main steam and feedwater piping supports inside containment. In this report, the seismic reanalysis of main steam and l feedwater piping supports inside containment was performed in accordance with the requirements of the 1980 Edition (including Winter 1982 addenda) of the ASME Code,Section III, Division 1, Subsection NF for component supports.
