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 rod insertion limits

2) Rod program group positions

3) Axial power shaping rod insertion limits

4) AXIAL POVER IMBALANCE operating limita and

5) QUADRANT POVER TILT limits
