' ANO Unit 1 Cycla 16 COLR CALC-98-R-1020-04 Rrav. O ENTERGY OPERATIONS ARKANSAS NUCLEAR ONE - UNIT ONE CYCLE 16 CORE OPERATING LIMITS REPORT 1.0 CORE OPERATING LIMITS This Core Operating Limits Report for ANO-1 Cycle 16 has been prepared in accordance with the requirements of Technical Specification 6.12.3. The core operating limits have been developed using the methodology provided in the references.

The following cycle - specific core operating limits are included in this repon:

1) Regulating control rod position setpoints,
2) Reactor power imbalance setpoints,
3) LOCA limited maximum allowable linear heat rate limits,
4) Axial power imbalance protective limits,
5) Protection system maximum allowable setpoints for axial power imbalance,
6) Variable Low RCS Pressure-Temperature (P-T) Protective Limits,
7) RCS Pressure-Temperature (P-T) Protective Maximum Allowable Setpoints,
8) KW/ft limit for axial power imbalance protective limits,
9) Minimum shutdown margin,
10) Axial power shaping rod insertion limits and setpoints,
11) Quadrant power tilt limits,
12) Design Nuclear Power Peaking Factors.
