1.0 INTRODUCTION
The Core Operating Limits Report (COLR) for Plant Hatch Unit 2 Cycle 24 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 2 Cycle 24 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 is the maximum allowable scram setpoint 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 2 operation. TABLE 1-1 Main Turbine Bypass System Operability System Operability Requirement Main Turbine Bypass System Operable At least two bypass valves must be (Technical Specification 3.7.7) operable-1 I 1 Version 1 Plant Hatch Unit 2 Cycle 24 Core Operating Limits Report Non-Proprietary Information From a fuel thermal limits perspective, the following limitations are placed on Unit 2 operation. TABLE 1-2 Equipment-Out-of-Service Limitations Equipment I Condition Limitation e CTP must be _ 2000 MWth Single-Loop Operation (SLO)

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 MCPR limit, MCPRF, as determined by Table 3-2, OR 2) The power-dependent MCPR limit, MCPRp, as determined by Table 3-3.b. For power _ 45%, the OLMCPRs are the greater of either: 1) MCPRF, as determined by Table 3-2, OR 2) The product of the power-dependent multiplier, Kp, as determined by Table 3-4, and the rated-power OLMCPR, as determined by Table 3-5.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 3-4B figures, Option A scram time OLMCPRs correspond to t = 1.0, where -c 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.7 Version 1 Plant Hatch Unit 2 Cycle 24 Core Operating Limits Report Non-Proprietary Information The average scram time of the control rods, t, is defined as: Tave -TB= 0, OR , whichever is greater.TA -TB where: TA = 1.08 sec (Technical Specification 3.1.4, Table 3.1.4-1, scram time limit to notch 36).TB + ji1.65 -a1 where: jt = 0.822 sec (mean scram time used in the transient analysis). a = 0.018 sec (standard deviation of ji).N 1 = total number of active rods measured in Technical Specifications Surveillance Requirement 3.1.4.1.n = number of surveillance tests performed to date in the cycle.Ni = number of active control rods measured in the ith surveillance test.-1=1r Tave -wErN, i=1 where: Ti =average scram time to notch 36 of all rods in the ith surveillance test.8 Version 1 Plant Hatch Unit 2 Cycle 24 Core Operating Limits Report Non-Proprietary Information TABLE 3-1 Exposure Definitions Exposure Label Cycle Exposure Definition BOC Beginning of Cycle 0 MWd/ST Exposure MOC1 First Middle of Cycle EOR -7945 MWd/ST Exposure MOC2 Second Middle of Cycle EOR -4945 MWd/ST Exposure Projected end of rated power with all control rods out at EOR End of Rated Exposure rated core flow and rated feedwater temperature EOC End of Cycle Exposure Exposure at cycle shutdown 9 Version 1 Plant Hatch Unit 2 Cycle 24 Core Operating Limits Report Non-Proprietary Information TABLE 3-2 Flow-Dependent MCPR Operating Flexibility Options MCPRF Equipment In or Out of Service EOC-RPT Main Turbine Main Turbine High Pressure Figure#System In Bypass System Pressure Regulator Feedwater Heaters Service Operable* System Status In Service Yes/No Yes/No TLCO 3.3.13.a or b Yes/No 3-1 Yes/No Yes/No TLCO 3.3.13.c Yes 3-1 Yes/No Yes/No TLCO 3.3.13.c No Not Licensed TABLE 3-3 Power-Dependent MCPR Operating Flexibility Options MCPRp from > 24% to < 45% Power Equipment In or Out of Service EOC-RPT Main Turbine Main Turbine High Pressure Figure #System In Bypass System Pressure Regulator Feedwater Service Operable* System Status Heaters In Service Yes/No Yes TLCO 3.3.13.a or b Yes/No 3-2A Yes/No No TLCO 3.3.13.a or b Yes/No 3-28 Yes/No Yes/No TLCO 3.3.13.c Yes 3-28 Yes/No Yes/No TLCO 3.3.13.c No Not Licensed TABLE 3-4 Power-Dependent Multiplier Flexibility Options Kp for Power > 45% of Rated Equipment In or Out of Service EOC-RPT Main Turbine Main Turbine High Pressure Figure #System In Bypass System Pressure Regulator Feedwater Heaters Service Operable* System Status In Service Yes/No Yes/No TLCO 3.3.13.a or b Yes 3-3A Yes/No Yes/No TLCO 3.3.13.a or b No 3-31 Yes/No Yes/No TLCO 3.3.13.c Yes 3-3C Yes/No Yes/No TLCO 3.3.13.c No Not Licensed* At least two bypass valves must be operable 10 Version 1 Plant Hatch Unit 2 Cycle 24 Core Operating Limits Report Non-Proprietary Information TABLE 3-5 Rated-Power MCPR Operating Flexibility Options Rated-power OLMCPRs Equipment TLO SLO In/Out of Service Equipment In Service 1 Figure 3-4A-1 Figure 3-4B-1 EOC-RPT Out of Service 1 Figure 3-4A-2 Figure 3-4B-2 Main Turbine Bypass Figure 3-4A-3 Figure 3-4B-3 System Inoperable 1 EOC-RPT Out of Service &Main Turbine Bypass Figure 3-4A-4 Figure 3-4B-4 System Inoperable 1 Main Turbine Pressure Regulator System in TLCO Table 3-6A Table 3-6B 3.3.13. c 2 1.

The flow-dependent multiplier, LHGRFACF, as determined by Table 4-2, OR b. The power-dependent multiplier, LHGRFACp, as determined by Table 4-3.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 4-3B show the LHGR limits for fuel segments with the lowest (UO 2) and highest (U0 2+Gd 2 O 3) initial Gd concentrations.
