PDB-FOO01 Page: 3 Rev.: 10 INTRODUCTION AND REFERENCES INTRODUCTION This Core Operating Limits Report for PNPP Unit 1 Cycle 10 is prepared in accordance with the requirements of PNPP Technical Specification Administrative Controls 5.6.5. The core operating limits presented were developed using NRC-approved methods (Reference 2). Results from the reload analysis for the General Electric fuel in PNPP Unit 1 for Cycle 10 are documented in References 3, 4 and 15.

The cycle-specific core operating limits for the following PNPP Unit 1 Technical Specifications are included in this report:

1. Average Planar Linear Heat Generation Rate (APLHGR) Limits for each fuel/lattice type, including the power and flow dependent MAPFAC curves with the single loop MAPLHGR reduction factor. (Technical Specification 3.2.1)

2. Minimum Critical Power Ratio Operating Limit including the power and flow dependent MCPR curves for Two Loop Operation and Single Loop Operation.

(Technical Specification 3.2.2) For Single Loop Operation the MCPR operating limits are increased by 0.01. (Reference 3)

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. (Technical Specification 3.2.3)

4. The simulated thermal power time constant. (Technical Specification 3.3.1.1, SR 3.3.1.1.14)

5. Oscillation Power Range Monitor (OPRM) Instrumentation. (Technical Specification 3.3.1.3)

PERRY UNIT 1 CYCLE 10 CORE OPERATING LIMITS REPORT

PDB-FOO01 Page: 5 Rev.: 10 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 values* 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 The following table lists the MAPLHGR limits as a function of exposure for GE12 fuel:

Exposure (GWD/st) ECCS MAPLHGR Limit (KW/FT) 0.00 10.90 13.24 10.90 21.61 10.90 63.50 6.39 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.

• These applicable MAPLHGR values 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 (GE12) and Figure 3.2.1-4 (GE14) for the applicable type of fuel.

PDB-FOO01 Page: 10 Rev.: 10 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 MCPRp 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 10 is 1.10. The MCPR Safety Limit for Single Loop Operation is 1.11 <TECHNICAL SPECIFICATIONS 2.1.1.2>. During Single Loop Operation, the Maximum Fraction of Limiting Critical Power Ratio (MFLCPR) shall be equal to or less than 0.99. Use FTI-B12 Single Loop Operation to implement this revised MFLCPR.

NOTE 1: For Cycle 10 no change to MCPR limits is required for planned reduction of feedwater temperature to as low as 325.5 0F. Final feedwater temperature may be reduced to 255.5 0F after all control rods are withdrawn at the end of cycle.

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.

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 are provided 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.

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 0.01 to account for the increase in the single loop MCPR safety limit with the reactor recirculation system in Single Loop Operation.

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.
