(Technical Specification 3.2.2)

Additional power dependent MCPR curves for Two Loop Operation and Single Loop Operation are provided for operation with one pressure regulator out of service.

3. Linear Heat Generation Rate (LHGR) Limits for each fuel/lattice type, including the power and flow dependent MAPFAC curves with the single loop MAPLHGR reduction factor. (Technical Specification 3.2.3)

PERRY UNIT I CYCLE 11 CORE OPERATING LIMITS REPORT

PDB-FO001 Page: 5 Rev.: 13 AVERAGE PLANAR LINEAR HEAT GENERATION RATE (TS 3.2.1)

All AVERAGE PLANAR LINEAR HEAT GENERATION RATES (APLHGRs) shall not exceed the result obtained from multiplying the applicable MAPLHGR limits* by the smaller of either the flow dependent MAPLHGR factor (MAPFACf) Figure 3.2.1-1 or the power dependent MAPLHGR factor (MAPFACp) Figure 3.2.1-2.

The following table lists the MAPLHGR limits as a function of exposure for GE14 fuel:

Exposure (GWD/st) ECCS MAPLHGR Limit (KW/FT) 0.00 12.82 14.51 12.82 19.13 12.82 57.61 8.00 63.50 5.00 NOTE: MAPLHGR Limits are defined in Reference 3. MAPFACf and MAPFACp are defined in Reference 15.

NOTE: The Single Loop Operation limits take effect when reset for single loop operation per LCO 3.4.1,"Recirculation Loops Operating". This is consistent with note "(b)" to Table 3.3.1.1-1 of the Technical Specifications. Use FTI-B0012 Single Loop Operation to implement the revised MAPLHGR Limits.

These applicable MAPLHGR limits are:

1. Those for the respective fuel as a function of the average planar exposure (as described by the NRC approved methodology described in GESTAR-II) or,

2. When hand calculations are required, the MAPLHGR limit as a function of the average planar exposure as shown in Figures 3.2.1-3 (GEl4).

Figure 3.2.1-3 PERRY UNIT 1 CYCLE II CORE OPERATING LIMITS REPORT

PDB-FO001 Page: 9 Rev.: 13 MINIMUM CRITICAL POWER RATIO (TS 3.2.2)

The MINIMUM CRITICAL POWER RATIO (MCPR) shall be equal to or greater than the higher of the MCPRf and MCPR, limits at the indicated core flow and THERMAL POWER as specified in Figures 3.2.2-1 and 3.2.2-2 for Two Loop Operation and Figures 3.2.2-3 and 3.2.2-4 for Single Loop Operation.

The MCPR Safety Limit for Cycle 11 is 1.08 and the MCPR Safety Limit for Single Loop Operation is 1.10 <TECHNICAL SPECIFICATIONS 2.1.1.2> (Reference 3 and 17). During Single Loop Operation with 3D MONICORE monitor in "2 LOOPS ON" mode, the Maximum Fraction of Limiting Critical Power Ratio (MFLCPR) shall be equal to or less than 0.98. Use FTI-B0012 Single Loop Operation to implement this revised MFLCPR.

NOTE 1: For Cycle 11 no change to MCPR limits is required for planned reduction of feedwater temperature to as low as 325.5 0 F. Final feedwater temperature may be reduced to 255.5*F after all control rods are withdrawn at the end of cycle if the OPRMs are OPERABLE.

NOTE 2: Planned reduction of rated feedwater temperature from nominal rated feedwater temperature is not permitted during plant operation with the reactor recirculation system in Single Loop Operation, if the OPRMs are operable.

NOTE 3: Figures 3.2.2-1 and 3.2.2-2 depict the limiting fuel type for Two Loop Operation. Figures 3.2.2-3 and 3.2.2-4 depict the limiting fuel type for Single Loop operation. Specific values are found in References 3 and 15.

Figures 3.2.2-5 and 3.2.2-6 depict power dependent MCPR curves for Two Loop Operation and Single Loop Operation for operation with one pressure regulator out of service. This may be implemented as either a change to the core monitoring software or appropriate administrative limit.

Figure 3.2.2-7 depicts implementing an administrative limit to the Maximum Fraction Limiting Critical Power Ratio with One Pressure Regulator Out Of Service.

In the case where a Pressure Regulator is out of service and the plant is in Single Loop Operations, limit MFLCPR to the smaller of 0.98 and Figure 3.2.2-7, MFLCPR Limit With One Pressure Regulator Out Of Service.

NOTE 4: There are a total of 19 safety/relief valves, the two lowest setpoint valves are assumed to be out-of-service in the transient analysis.

NOTE 5: The MCPR operating limit is increased 0.02 to account for the increase in the single loop MCPR safety limit with the reactor recirculation system in Single Loop Operation.

PERRY UNIT 1 CYCLE 11 CORE OPERATING LIMITS REPORT

PDB-F0001 Page: 10 Rev.: 13 NOTE 6: The Single Loop Operation limits take effect when reset for Single Loop Operation per LCO 3.4.1, "Recirculation Loops Operating". This is consistent with note "(b)" to Table 3.3.1.1-1 of the Technical Specifications.

NOTE 7: The standard off-rated limits established as part of the GEl4 new fuel introduction from Cycle 9 are applicable for the current Cycle 11 with the appropriate scaling. The SLMCPR basis for MCPR(P) limits below Pbypass for GEl4 is 1.10, and the MCPR(F) coefficients are based on a SLMCPR of 1.07. Therefore, scaling of (1.08/1.10) was applied to the MCPR(P) graphs and scaling of (1.08/1.07) is applied to MCPR(F) coefficients to account for the changes in the SLMCPR (Reference 3).
