Th'e core Operating l Limits have been developeo using the methodology provided in reference 2.0 (1). The licensed length of Cycle 12 is 684 EFPDs.

l The following cycle-specific core Operating Limits, Protective Limit and Flux -A Flux / Flow Reactor Protection System Allowable alues 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) QUADRANTPOWERTILTlimits
8) Negative Moderator Temperature Coefficient limit
