Data Point Library Modifications Ladies and Gentlemen:
In accordance with the requirements of 10 CFR 50, Appendix E.Section VI, Item 3a, Southern Nuclear Operating Company is submitting changes to the Vogtle Electric Generating Plant Unit 1 Emergency Response Data System (EROS) data point library. Data points UV0403 (Steam Generator 1 Main Feedwater Flow),
UV0423 (Steam Generator 2 Main Feedwater Flow), UV0443 (Steam Generator 3 Main Feedwater Flow). and UV0463 (Steam Generator 4 Main Feedwater Flow) were revised as a result of the Unit 1 Measurement Uncertainty Recapture (MUR)
Power Uprate implementation during the Unit 1 spring 2008 refueling outage.
The changes were completed on April 30. 2008.
This letter contains no NRC commitments. If you have any questions, please advise. Y
