DearMr.Vissing:

Initsresponse, RG&Emadeacommitment tocollateandvalidateselectedinformation forspecificsystemsandtopicsandlinkthisinformation electronically withtheUFSAR.Further,RG&Estatedthatitsscheduleforcompletion oftheaboveexamination andverification ofsystemandtopicaldesignbasesinformation hadnotbeenestablished yet,thatitintendedtodevelopafirmscheduleinthethirdquarterof1997,andthatitwouldprovidethescheduletotheNRCatthattime.RG&Ehasrecognized theneedtoputinplaceaninformation technology (IT)infrastructure tosupportcontinued maintenance ofthedatacollected fromtheUFSARverification anddesignbasisdocumentation

projects, bothofwhichareinprogress.
