1.0 Core Operating Umits Report This Core Operating Limits Report for Cycle 26 has been prepared in accordance with the requirements of Technical Specification 5.6.5 and is applicable to operation for which rated thermal power is 1912 MWt. The core operating limits have been developed using NRC-approved methodology (Reference 1) and are established such that all applicable limits of the plant safety analysis are met.

The Cycle 26 values for the core operating limits are provided in Section 3.0 of this report.

1. Average Planar Linear Heat Generation Rate (APLHGR) - TS 3.2.1
a. The Maximum APLHGR (MAPLHGR) applicable to all fuel types as a
  • function of Planar Average Exposure (PAE) shall not exceed the limiting' curves defined by Table 1, multiplied by the smaller of the two MAPFAC/LHGRFAC factors determined from Figures 2a and 3 [also use Figures 2a and 3 for Recirculation Pump Trip Out-of-Service (RPTOOS); Figures 2b and 3 for Turbine Bypass Valves Out-of-Service (TBVOOS); Figures 2c and 3 for RPTOOS and TBVOOS]. Figure 1 plots the MAPLHGR curve co~responding to Table 1.
b. The Maximum Linear Heat Generation Rate (MLHGR) applicable to all fuel rods for all fuel types as a function of Peak Pellet Exposure (PPE) shall not exceed the curves defined by Table 2, multiplied by the smaller of the two MAPFAC/LHGRFAC factors determined from Figures 2a and 3 [also use Figures 2a and 3 for Recirculation Pump Trip_Out-of-Service (RPTOOS); Figures 2b and 3 for Turbine Bypass Valves Out-of-Service (TBVOOS); Figures 2c and 3 for RPTOOS and TBVOOS].
c. During Single Loop Operation (SLO), the actual MAPLHGR applicable to all fuel types as a function of planar average exposure shall not exceed the limiting curves defined by Table 1, multiplied by the smaller of the two MAPFAC/LHGRFAC factors determined from Figures 2a and 4 [also use Figures 2a and 4 for Recirculation Pump Trip Out-of-Service (RPTOOS); Figures 2b and 4 for Turbine Bypass Valves Out-of-Seri/ice (TBVOOS); Figures 2c and 4 for RPTOOS and TBVOOS].
d. During Single Loop Operation (SLO), the actual MLHGR applicable to all fuel rods for all fuel types as a function of peak pellet exposure shall not exceed the limiting curves deffned by Table 2, multiplied by the smaller of the two MAPFAC/LHGRFAC factors determined from Figures 2a and 4 [also use Figures 2a and 4 for Recirculation Pump Trip Out-of-Service (RPTOOS); Figures 2b and 4 for Turbine Bypass Valves Out-of-Service (TBVOOS); Figures 2c and 4 for RPTOOS and TBVOOS].

The above MAPLHGR limits are from the Emergency Core Cooling requirements of the Loss-of-Coolant Accident (LOCA) analyses. The above MLHGR limits are from the fuel thermal-mechanical performance limits. The individual MAPLHGR and MLHGR limits, as discussed in the BASES for TS 3.2.1, are modeled in the process computer. The above can be used to determine the TS MAPLHGR or MLHGR limits in the event the process computer is not available.

2. Minimum Critical Power Ratio (MCPR) - TS 3.2.2
a. The MCPR shall be equal to or greater than the Operating Limit MCPR (OLMCPR), which is a function of Core Thermal Power, Core Flow, and Scram Time (Tau). For Core Thermal Power greater than or equal to 21.7% of rated and less than 40% of rated (21.7% ::> P < 40%), the OLMCPR is given by Figure Sa [also use Figure Sa for Recirculation Pump Trip Out-of-Service (RPTOOS); Figure Sb for Turbine Bypass Valves Out-of-Service (TBVOOS); Figure Sc for RPTOOS and TBVOOS].

For Core Thermal Power greater than or equal to 40% of rated (P;:: 40%),

the OLMCPR is the greater of either:

i) The applicable flow-dependent OLMCPR determined from Figure 6, or ii) The appropriate Rated Power OLMCPR from Figure 7 or 8 [Figure 9 for Recirculation Pump Trip Out-of-Service (RPTOOS); Figure 1O for Turbine Bypass Valves Out-of-Service (TBVOOS); Figure 11 for RPTOOS and TBVOOS], multiplied by the applicable power-dependent OLM CPR multiplier determined from Figure Sa [also use Figure 5a for Recirculation Pump Trip Out-of-Service (RPTOOS);

Figure Sb for Turbine Bypass Valves Out-of-Service (TBVOOS);

Figure Sc for RPTOOS and TBVOOS].

b. During SLO with Core Thermal Power greater than or equal to-21.7% of rated, the SLO OLMCPR is the greater of either:

i) adding 0.03 to the OLMCPR determined above, or ii) a rated OLMCPR of 1.43, multiplied by the applicable power-dependent OLMCPR multiplier determined from Figure Sa [also use Figure Sa for Recirculation Pump Trip Out-of-Service (RPTOOS);

Figure Sb for Turbine Bypass Valves Out-of-Service (TBVOOS);

Figure Sc for RPTOOS and TBVOOS].

The above can be used to determine the TS OLM CPR limits in the event the process computer is not available.
