Duke Energy Carolinas, LLC Oconee Nuclear Station Docket Numbers 50-269, 50-270, and 50-287 Submittal of Information in Support of the License Amendment Request to Revise the Oconee Nuclear Station Current Licensing Basis for High Energy Line Break Events Outside of the Containment Building," - License Amendment Request No.

Reference:

Letter from Dave Baxter, Site Vice President, Oconee Nuclear Station, Duke Energy Carolinas, LLC, to the U. S. Nuclear Regulatory Commission, "Proposed License Amendment Request to Revise the Oconee Nuclear Station Current Licensing Basis for High Energy Line Break Events Outside of the Containment Building," dated June 29, 2009.

On June 29, 2009, Duke Energy Carolinas, LLC (Duke) submitted a License Amendment Request (LAR) to revise the Oconee Nuclear Station (ONS) Current Licensing Basis for High Energy Line Break Events Outside of the Containment Building [Ref].

Consistent with the Unit 1 and Unit 2 HELB LAR submittals, Duke supplied the Unit 3 updates to report ONDS 351, "Analysis of Postulated High Energy Line Breaks (HELBs)

Outside Containment," that contained drawings and tables to describe breaks postulated throughout the plant. The NRC Staff identified later that some of the tables had not been received and that a Figure (9-44) had not been included in the Unit 1 HELB LAR. Both the missing tables and figure are included as an attachment to this letter.

If you have any questions in regard to this letter, please contact Stephen C. Newman, Regulatory Compliance Lead Engineer, Oconee Nuclear Station, at (864) 873-4388.
