. KIP 539

Dear Mr. Diamantstein:

Attached are the peak ground acceleration and spectral values you requested in your fax of September 27, 1993 for the Ginna and Fitzpatrick nuclear power plant sites.

These probabilistic hazard estimates were developed by Lawrence.

i Livermore National Laboratory (LLNL) in 1993. We are developing a NUREG report which will summarize the 1992/1993 LLNL probabilistic hazard work performed for the Office of Nuclear Reactor Regulation. The probabilistic hazard results for each nuclear power plant site in the Eastern United States will be included in the report a tables of dita.

If you have any questions

.j about the attached data please call me at 301-504-2738.
