Cycle 15 COLR Page 4 of31 Revision 0 FIRSTENERGY NUCLEAR OPERATING COMPANY DAVIS-BESSE UNIT 1 CYCLE 15 CORE OPERATING LIMITS REPORT 1.0 Core Operating Limits This CORE OPERATING LIMITS REPORT for DB-1 Cycle 15 has been prepared in accordance with the requirements of Technical Specification 6.9.1.7. The Core Operating Limits have been developed using the methodology provided in reference 2.0 (1). The licensed length of Cycle 15 is 711.36 EFPDs (based on a reactor thermal rating of 2772 MWt).

The following cycle-specific core Operating Limits, Protective Limit and Flux -AFlux/Flow Reactor Protection System Allowable Values are included in this report:

1) Regulating Group Position Alarm Setpoints (error adjusted Operating Limits) and Xenon reactivity "power level cutoff'
2) Rod program group positions (Control Rod Core locations and group assignments)
3) Axial Power Shaping Rod Alarm Setpoints (error adjusted Operating Limits)
4) AXIAL POWER IMBALANCE Alarm Setpoints (error adjusted Operating Limits)
5) AXIAL POWER IMBALANCE Protective Limits
6) Flux-AFlux/Flow (or Power/Imbalance/Flow) Allowable Values.
7) QUADRANT POWER TILT limits
8) Negative Moderator Temperature Coefficient limit
9) Nuclear Heat Flux Hot Channel Factor, FQ and
10) Nuclear Enthalpy Rise Hot Channel Factor, FN,,
