ONEI-0400-70 Rev 31 Page 4 of 33 Oconee 3 Cycle 26 1.0 Error Adjusted Core Operating Limits The Core Operating Limits Report for 03C26 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.

The RPS protective limits and maximum allowable setpoints are documented in References 12 through 14. These limits are validated for use in O3C26 by References 15 through 17. The 03C26 analyses assume a design flow of 108.5% of 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 for 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 report incorporate all necessary uncertainties and margins required for operation of the 03C26 reload core.
