ENTERGY OPERATIONS 9

ARKANSAS NUCLEAR ONE - UNIT ONE CYCLE 13 .

CORE OPERATING LIMITS REPORT l 1.0 CORE OPERATING LIMITS This Core Operating Limits Repon for ANO-1 Cycle 13 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  !

report:

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) KW/ft limit for axial power imbalance protective limits,
7) Minimum shutdown margin,
8) Axial power shaping rod insertion limits,
9) Quadrant power tilt limits.
