/ Oconee 1 Cycle 26 1.0 Error Adjusted Core Operating Limits The Core Operating Limits Report for 01C26 has been prepared in accordance with the requirements of TS 5.6.5. The core operating limits within this report have been developed using NRC approved methodology reports identified in References 1 through 11. See the discussion below pertaining to References 2 through 8.

01C26 is the third reload of the AREVA Mark-B-HTP fuel design. Revisions to seven NRC-approved Duke methodology reports (References 2 through 8) were submitted to NRC for review and approval to support the transition to the Mark-B-HTP fuel. These revisions were combined into one new methodology report, DPC-NE-2015-P, "Mark-B-HTP Fuel Transition Methodology". The DPC-NE-2015-P. methodology report was approved by the NRC in a Safety Evaluation Report (SER) dated October 29, 2008. This SER allows Duke to incorporate the NRC's previously reviewed & approved HTP-related changes into References 2 through 8.

The core operating limits have been developed using the methodologies from revised References 2, 4, 5, and 6 and existing References 3, 7, and 8 with the NRC-approved changes.resulting from the NRC approval of the DPC-NE-2015-P report.

The RPS protective limits and maximum allowable setpoints are documented in References 12 through 14. These limits are validated for use in 01C26 by References 15 through 17. The 01C26 analyses assume a design flow of 108.5%

of 88,000 gpm per RCS pump, a radial local peaking (FAh) of 1.714, an axial peaking factor (Fz) of 1.5, and an EOC

(< 100 ppmB) Tavg reduction fo up to 10°F provided 4 RCPs are in operation and Tavg does not decrease below 569°F.

The error adjusted core operating limits included in section 1 of the reportincorporate all necessary uncertainties and margins required for operation of the 01C26 reload core.
