Dear Mr. Vissing:

References 2 S 3 mentioned the availability of the subject database on the NRC website and gave access instructions. Rochester Gas 0 Electric PGSE) retrieved and reviewed the database, particularly as it pertains to the R. E. Ginna Nuclear Power Plant.

Reviewing the database, we found that for the Ginna reactor vessel (RV) limiting material, which is Heat ID 61782, Circ. Weld, SA-847, the calculated values of several parameters derived &om information submitted in Reference 1 had not been incorporated in the new version 2 of the database. These parameters are listed below:

Parameter RVID Ver.2 Current Value (per Ref. 1)

1. Chemistry Factor 158.7 F 160.7 F
2. Delta RTndt@EOL 210.4 F 213.08 F
3. RTpts @ EOL 253.9 F 256.58 F Pod sttctt0ttt08003ttt 'stt9083i PDR ADOCK 05000244 P PDR

These parameters are entered in two parts of the RVID, the Weld Detail Data Page and the PTS Summary Report Page.

Data for other welds, forgings, and plate materials are correct as we found no other discrepancies.

We request that in your next revision of the RVID, the above parameters be updated to reflect the new data that we submitted in Reference 1, as shown above. This is particularly important since the data pertains to the Ginna RV limiting weld which has been utilized to generate Ginna heat up Ec cooldown curves up to 40 EFPY (Effective Full Power Years).

We sincerely appreciate and offer our thanks for your consideration of this request.

Very t ly yours, Robert C. Mecredy xc: Mr. Guy S. Vissing (Mail Stop 8C2)
