Subject:
Oconee Nuclear Site Docket Nos. 50-269, 50-270 and 50-287 Revision to the 2001 Annual Effluent Release Report Gentlemen:
Attached are revised pages for the 2001 Oconee Annual Effluent Release Report.
The revision is due to incorrect data entry of tritium concentration values for the Unit Vent, 3RIA53, and 4RIA45 monthly effluent calculations.
The data entry corrections resulted in an additional 12.1 curies of airborne tritium for 2001.
The calculated maximum airborne organ dose increased to 3.83E-02 mrem from 3.52E-02 mrem representing less than 0.1 percent of the 45 mrem annual Selected Licensee Commitments maximum airborne organ dose limit.
Should there be questions concerning this report please contact Judy E. Smith at (864) 885-4309.
Very truly yours, 34 kU{9 t~4 R. A. Jones Site Vice President Oconee Nuclear Site Attachments www duke-energy corn
