1.0 INTRODUCTION
Non-Proprietary Information Core Operating Limits Report The Core Operating Limits Report (COLR) for Plant Hatch Unit 1 Cycle 28 is prepared in accordance with the requirements of Technical Specification 5.6.5. The core operating limits presented herein were developed using NRC-approved methods (References 1 through 6). Results from the reload analyses for the fuel in Unit 1 Cycle 28 are documented in References 3 through 5.
The following core operating limits are included in this report:.
- a. Average Planar Linear Heat Generation Rate (APLHGR)- Technical Specification 3.2.1
- b. Minimum Critical Power Ratio (MCPR) - Technical Specification 3.2.2
- c. Linear Heat Generation Rate (LHGR) - Technical Specification 3.2.3 Also included in this report are the licensed scram setpoints for the Period Based.
Detection Algorithm (PBDA) in the Oscillation Power Range Monitor (OPRM).
Based upon the reload analysis for this cycle, the following operability requirement is defined for Unit 1 operation.

Core Operating Limits Report For both two loop operation (TLO) and single loop operation (SLO), the APLHGR limit for each six inch axial segment of each fuel assembly in the core is the applicable fuel-type-specific APLHGR limit in Figure 2-2 multiplied by the fuel-type-specific flow-dependent multiplier, MAPFACF, taken from either:
- a. Figure 2-1A for GE14C fuel
- b. Figure 2-1 B for GNF2 fuel.

Version 1
Plant Hatch Unit 1 Cycle 28 Non-Proprietary Information 3.0 MCPR OPERA TING LIMITS (Technical Specification 3.2.2)
Core Operating Limits Report The MCPR operating limits (OLMCPR) for each fuel type are a function of core power, core flow, average scram time, number of operating recirculation loops, EOC-RPT system status, operability of the main turbine bypass system, the status of the main turbine pressure regulator system, and cycle exposure. Cycle exposures are defined in Table 3-1.
The OLMCPRs for both two loop operation (TLO) and single loop operation (SLO) are determined as follows:
a: For 24% ~power< 45%, the greater of either:
- 1) The flow-dependent MCPRlimit, MCPRF, as determined by Figure 3-1, OR
- 2) The power-dependent MCPR limit, MCPRp, as determined by Table 3-2.
- b. For power~ 45%, the *greater of either:
- 1) MCPRF, as determined by Figure 3-1, OR
- 2) The product of the power-dependent multiplier, Kp, as determined by Table 3-3, and the rated-power OLMCPR, as determined by Table 3-4.
These limits apply to all modes of operation with feedwater temperature reduction, as well as operation with normal feedwater temperatures.
In the 3-4A and 3-48 figures, Option A scram time OLMCPRs correspond to 't = 1.0, where 't is determined from scram time measurements performed in accordance with Technical Specifications Surveillance Requirements 3.1.4.1 and 3.1.4.2. Option B values correspond to 't = 0.0. For scram times between Option A and Option B; the rated-power OLMCPR corresponds to 't. If 't has not been determined, Option A limits must be used.

Plant Hatch Unit 1 Cycle 28 Non-Proprietary Information Core Operating Limits Report 4.0 LHGR LIMITS (Technical Specification 3.2.3)
Fuel For both two loop operation (TLO) and single loop operation (SLO), the LHGR limit for each six inch axial segment of each fuel rod in the core is the applicable rated-power, rated-flow LHGR limit taken from Table 4-1 multiplied by the smaller of either:
- a. The flow-dependent multiplier, LHGRFACF, as determined by Table 4-2,
- c. The power-dependent multiplier, LHGRFACp, as determined by Figure 4-2.
Table 4-1 shows the exposure-dependent LHGR limits for all fuel types in the core, as a function of initial gadolinium concentration in a six inch segment of a fuel rod. For exposures between the values shown in Table 4-1, the LHGR limit is based on linear interpolation. For illustration purposes, Figures 4-3A and 4-38 show the LHGR limits for fuel segments with the lowest (U02) and highest (U02+Gd203) initial Gd concentrations.

1.0 INTRODUCTION
Non-Proprietary Information Core Operating Limits Report The Core Operating Limits Report (COLR) for Plant Hatch Unit 1 Cycle 28 is prepared in accordance with the requirements of Technical Specification 5.6.5. The core operating limits presented herein were developed using NRC-approved methods (References 1 through 6). Results from the reload analyses for the fuel in Unit 1 Cycle 28 are documented in References 3 through 5.
The following core operating limits are included in this report:.
- a. Average Planar Linear Heat Generation Rate (APLHGR)- Technical Specification 3.2.1
- b. Minimum Critical Power Ratio (MCPR) - Technical Specification 3.2.2
- c. Linear Heat Generation Rate (LHGR) - Technical Specification 3.2.3 Also included in this report are the licensed scram setpoints for the Period Based.
Detection Algorithm (PBDA) in the Oscillation Power Range Monitor (OPRM).
Based upon the reload analysis for this cycle, the following operability requirement is defined for Unit 1 operation.

Version 1
Plant Hatch Unit 1 Cycle 28 Non-Proprietary Information 3.0 MCPR OPERA TING LIMITS (Technical Specification 3.2.2)
Core Operating Limits Report The MCPR operating limits (OLMCPR) for each fuel type are a function of core power, core flow, average scram time, number of operating recirculation loops, EOC-RPT system status, operability of the main turbine bypass system, the status of the main turbine pressure regulator system, and cycle exposure. Cycle exposures are defined in Table 3-1.
The OLMCPRs for both two loop operation (TLO) and single loop operation (SLO) are determined as follows:
a: For 24% ~power< 45%, the greater of either:
- 1) The flow-dependent MCPRlimit, MCPRF, as determined by Figure 3-1, OR
- 2) The power-dependent MCPR limit, MCPRp, as determined by Table 3-2.
- b. For power~ 45%, the *greater of either:
- 1) MCPRF, as determined by Figure 3-1, OR
- 2) The product of the power-dependent multiplier, Kp, as determined by Table 3-3, and the rated-power OLMCPR, as determined by Table 3-4.
These limits apply to all modes of operation with feedwater temperature reduction, as well as operation with normal feedwater temperatures.
In the 3-4A and 3-48 figures, Option A scram time OLMCPRs correspond to 't = 1.0, where 't is determined from scram time measurements performed in accordance with Technical Specifications Surveillance Requirements 3.1.4.1 and 3.1.4.2. Option B values correspond to 't = 0.0. For scram times between Option A and Option B; the rated-power OLMCPR corresponds to 't. If 't has not been determined, Option A limits must be used.

Plant Hatch Unit 1 Cycle 28 Non-Proprietary Information Core Operating Limits Report 4.0 LHGR LIMITS (Technical Specification 3.2.3)
Fuel For both two loop operation (TLO) and single loop operation (SLO), the LHGR limit for each six inch axial segment of each fuel rod in the core is the applicable rated-power, rated-flow LHGR limit taken from Table 4-1 multiplied by the smaller of either:
- a. The flow-dependent multiplier, LHGRFACF, as determined by Table 4-2,
- c. The power-dependent multiplier, LHGRFACp, as determined by Figure 4-2.
Table 4-1 shows the exposure-dependent LHGR limits for all fuel types in the core, as a function of initial gadolinium concentration in a six inch segment of a fuel rod. For exposures between the values shown in Table 4-1, the LHGR limit is based on linear interpolation. For illustration purposes, Figures 4-3A and 4-38 show the LHGR limits for fuel segments with the lowest (U02) and highest (U02+Gd203) initial Gd concentrations.
