DearMr.Vissing:
Recenttelephone conversations betweentheNRCandRG&Ediscussed concernsregarding highIn-structure ResponseSpectrashowninRochester Gas&Electric's January1997USI-A46submittal.
Rochester Gas&Electricprovidedexplanations inresponses totheNRCRAI's(Ref.A&C)on5/27/98and2/2/99(Ref.B&D).Thesediscussions focusedonwhetherGinnastructures, suchasthedieselgenerator
- building, couldbeconsidered "typicalnuclearstructures".
RG&Eagreedtosupplement ourFebruary1999submittal regarding qualitative explanations ofseismicresponsespectramarginswithsomequantitative examples.
