No: 3-GRAPH-RPC-16 Rev: 7 CORE OPERATING LIMITS REPORT Page 4 of 12 NOTE The data presented in this report applies to Cycle 19 ONLY and may NOT be used for other cycles of operation. Also, it applies only to operation at a maximum power level of 3188.4 MWt. Any technical change to this document may require a Safety Evaluation to be performed in accordance with 10 CFR 50.59.
TS 2.1.1 Reactor Core SLs In MODE 1 and 2, the combination of thermal power level, pressurizer pressure, and Reactor Vessel inlet temperature SHALL not exceed the limits shown in Figure 1. The safety limit is exceeded if the point defined by the combination of Reactor Vessel inlet temperature and power level is at any time above the appropriate pressure line.
TS 3.1.1 Shutdown Marain (SDM)
The shutdown margin SHALL be greater than or equal to 1.3% Ak/k.
TS 3.1.3 Moderator Temperature Coefficient (MTC)
The MTC upper limit SHALL be : 0.0 Ak/k/lF at hot zero power.
The MTC lower limit SHALL be less negative than or equal to:

-44.5 pcm/°F @ 60 ppm
-47.0 pcm/°F @ 0 ppm
No: 3-GRAPH-RPC-16 Rev: 7 CORE OPERATING LIMITS REPORT Page 5 of 12 TS 3.1.5 Shutdown Bank Insertion Limits The Shutdown Banks SHALL be fully withdrawn when the reactor is in MODE 1 and MODE 2. Shutdown Banks with a group step counter demand position _> 225 steps are considered fully withdrawn because the bank demand position is above the top of the active fuel.
TS 3.1.6 Control Bank Insertion Limits The Control Bank Insertion Limits for MODE 1 and MODE 2 with keff > 1.0 are as indicated in Figure 2. Control Bank Insertion Limits apply to the step counter demand position.
Each control bank shall be considered fully withdrawn at > 225 steps.

NOTE
- P is the fraction of Rated Thermal Power (RTP) at which the core is operating.
- K(Z) is the fraction given in Figure 3 and Z is the core height location of FQ.
