Subject:
Systematic Evaluation Program - Seismic Review R.
E. Ginna Nuclear Power Plant Docket No. 50-244
Dear Mr. Ziemann:
Enclosure I of my letter of July 3, 1979 indicated submittal dates for information relating to the mechanical systems and equipment requested by the NRC for the Systematic Evaluation Program -Seismic Review for Ginna Station.
My correspondence of July 16, 1979 indicated that because of outstanding IE Bulletin responses, it was necessary to review our current. engineering manpower commitments including SEP seismic review input.
Accordingly, enclosure I provides a new submittal schedule for the SEP mechanical systems and equipment items still outstanding.
- Also, a meeting on the SEP-seismic structural model was held at Reading, Pennsylvania on August 30, 1979 involving RG&E, Gilbert Associates, Lawrence Livermore Labs and the NRC (Mr. Tom Cheng).
As requested at that. meeting, RG6E gave Mr. Cheng a set of drawings of Ginna Station indicating the location and weight of major equipment loads.
Information was also requested relating to Cat. I equipment in the intermediate building and the structural framing on the east wall of the facade.
Enclosure II provides the requested information on the intermediate building.
A field inspection of the facade steel shows that drawing No. D-521-071 is correct as is.
To the best of our knowledge, this completes all currently outstanding structural seismic items.
