July 23, 2010 NG-10-0376 10 CFR 50.36a U.S. Nuclear Regulatory Commission Attn: Document Control Desk Washington, D.C. 20555-0001 Duane Arnold Energy Center Docket 50-331 License No. DPR-49

Reference:

Letter from Christopher R. Costanzo (NextEra Energy Duane Arnold) to Document Control Desk (USNRC) dated April 30, 2010, "2009 Annual Radioactive Material Release Report" and "Annual Radiological Environmental Operating Report," NG-10-0265 (ML101270480)

Revision to Annual Radioactive Material Release Report In the referenced letter, NextEra Energy Duane Arnold, LLC (hereafter, NextEra Energy Duane Arnold) submitted the Annual Radioactive Material Release Report as Enclosure 1. This report satisfies the requirements of Offsite Dose Assessment Manual (ODAM) Section 8.2.1 and Technical Specification Section 5.6.3.

A recent review of the referenced submittal by NextEra Energy Duane Arnold revealed that certain data on Page 14 of the report is incorrect. The Site Historical Comparison data table is hereby corrected to specify that the activity for 2008 is 134 Curies (Ci) instead of 1.34E+05 Ci and the activity for 2009 is 58.2 Ci instead of 5.82E+04 Ci. The title of the table provided on Page 16 of the report is also being corrected to specify "Summary of Radioactive Solid Waste - Contaminated Liquids" instead of "Summary of Radioactive Solid Waste - Class C" to reflect the actual content of the table. The enclosure to this letter provides replacement pages 14 and 16 of the 2009 Annual Radioactive Material Release Report.

NextEra Energy Duane Arnold regrets these errors and we sincerely apologize for any inconvenience this may cause the Staff.

If you have any questions, please contact Steve Catron at (319) 851-7234.
