This Core Operating Limits Report (COLR) for the Perry Nuclear Power Plant (PNPP) Unit 1 is prepared in accordance with the requirements of PNPP Technical Specification Administrative Control 5.6.5. The core operating limits presented herein were determined using NRC-approved methods (Obligation 1 and Obligation 2). The core operating limits for the Global Nuclear Fuel (GNF) fuel in PNPP Unit 1 for Cycle 18 are documented in Obligations 3, 4, 5, 14, 16, 17, and 20 and summarized herein for the following PNPP Unit 1 Technical Specifications:
- 1. Average Planar Linear Heat Generation Rate (APLHGR) Limits for each fuel/lattice type, including the power and flow dependent MAPFAC multipliers with the single loop MAPLHGR reduction factor. (Technical Specification 3.2.1)
- 2. Minimum Critical Power Ratio Limit including the Operating Limit MCPR along with the power and flow dependent MCPR curves. (Technical Specification 3.2.2)
Power dependent MCPR Limit curves are provided for operation with equipment in service (EIS), one pressure regulator out of service (PROOS), and power load unbalance out of service (PLUOOS).

28 5 of 25 The oscillation power range monitor setpoint methods have been changed to NEDE-33766P-A, GEH Simplified Stability Solution (GS3). The GS3 methods are a generic approach to establishing the OPRM period - based detection algorithm setpoints. This generic approach assumes feedwater temperature reductions are limited to 120F anytime during the cycle.
Cycle 18 (Reload 17) core design was developed assuming feedwater temperature reductions of 100F during the cycle and 170F beyond the end of the normal fuel cycle. Plant operations will be limited to 100F during the cycle to account for the assumptions of the core design and 120F beyond the end of the normal fuel cycle to account for the GS3 limitation.
Calculation FM-075, Support for the Core Operating Limits Report, details the development of the various graphs contained within this COLR.

All Average Planar Linear Heat Generation Rates (APLHGRs) shall be less than or equal to the result obtained from multiplying the applicable MAPLHGR limit by the smaller of either the flow dependent APLHGR factor (MAPFACf) or the power dependent APLHGR factor (MAPFACp).
MAXIMUM APLHGR LIMIT = MAPLHGR LIMIT
- smaller (MAPFACf or MAPFACp)
MAPLHGR Limits and MAPFACf and MAPFACp are defined in Obligation 3.

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.
The 3DMONICORE computer software will automatically shift between 2 LOOPS ON and 1 LOOP ON modes of operation on transfer to Single Loop Operation.
The change in MAPFACf and MAPFACp will occur automatically. Guidance in FTI-B0012 can be used to verify proper functioning of the 3DMONICORE System. If the 3DMONICORE System is not functioning properly, FTI-B0012 will implement administrative limits until 3DMONICORE is properly calculating MAPLHGR Limits.

28 10 of 25 4.0 T.S. 3.2.2 - MINIMUM CRITICAL POWER RATIO (MCPR)
All Minimum Critical Power Ratios (MCPRs) shall be greater than or equal to the MCPR Limit. The MCPR Limit is equal to the higher of the Operating Limit MCPR, the Flow Dependent MCPR (MCPRf), and the Power Dependent MCPR (MCPRp) plus the MCPR Limit Adder.
MCPR Limit = maximum (Operating Limit MCPR, MCPRf, MCPRp) +
MCPR Limit Adder Operating Limit MCPR along with MCPRf, MCPRp, and MCPR Limit Adder are defined in Obligation 3 and Obligation 20.
4.1 OPERATING LIMIT MCPR and MCPR LIMIT ADDER For Cycle 18, the Operating Limit MCPR is a function of the fuel type and exposure. Middle of Cycle (MOC) exposure point is defined as End of Rated (EOR) exposure point minus the Cycle Delta Exposure. For Cycle 18, the EOR exposure is defined in the Cycle 18 Cycle Management Report. For Cycle 18, the Cycle Delta Exposure is set to 2993 MWd/ST. Thus, MOC is equal to EOR -
2993 MWd/ST.
The End of Rated (EOR) is defined as the cycle exposure corresponding to all rods out, 100% power / 100% flow, and rated feedwater temperature. As such, the EOR is a projection based on various assumptions such as how the previous cycle operated, current cycle operations, core loading changes during the refueling outage, inoperable control rods, suppressed fuel defects, etc. The projected EOR exposure point may have to be updated during the cycle to ensure the appropriate MCPR limits applied (Obligation 16). The changes in the EOR value are documented in supplements or revisions to the Cycle Management Report.
The Operating Limit MCPR is additionally defined by the selected Flexibility Option:
Equipment In Service (EIS)
Pressure Regulator Out Of Service (PROOS)
Power Load Unbalance Out of Service (PLUOOS)

Operating Limit EIS/PROOS MCPR /PLUOOS BOC to < MOC 1.35 MOC to EOC 1.40 For Cycle 18, the MCPR Limit Adder is equal to 0.00.
For Cycle 18, no change to MCPR limits is required for planned reduction of feedwater temperature to as low as 325.5F. Final feedwater temperature may be reduced to 305.5F after all control rods are withdrawn at the end of cycle if the OPRMs are OPERABLE.
The 3DMONICORE computer software will automatically shift the Operating Limit MCPR based on the MOC exposure point.
4.2 FLOW DEPENDENT MCPRf The Flow Dependent MCPR Limit (MCPRf) is independent of fuel type, exposure, and the selected Flexibility Option (Equipment In Service, Pressure Regulator Out Of Service, and Power Load Unbalance Out Of Service).
The Flow Dependent MCPR Limit is depicted in the following figure:
Figure 3.2.2-1, Flow Dependent MCPR Limit (MCPRf) 4.3 POWER DEPENDENT MCPRp The Power Dependent MCPR Limit (MCPRp) is independent of the fuel type and exposure but is dependent on the Flexibility Option selected. MCPRp figures are provided for Equipment In Service (EIS) and Pressure Regulator Out Of Service /
Power Load Unbalance Out Of Service.
When operating below or equal to 38% RTP, MCPRp is independent of fuel type, exposure, and flexibility option.
