River Bend Station Core Operating Limits Report - Cycle 18 Revision 0 5.0 CORE DESIGN 5.1 Reference Core Loading Pattern The Reference Core Loading pattern is presented in Reference 3.1.1. 5.2 Control Rods The River Bend core utilizes the GE design control rods, non GE design CR-82M and CR-82M-1 bottom entry cruciform control rods. These control rod designs are discussed in more detail in Reference 3.1.4, Sections 4.1 and 4.2. 6.0 AVERAGE PLANAR LINEAR HEAT GENERATION RATE (APLHGR) Per Technical Specification 3.2.1, all APLHGR values shall not exceed the exposure-dependent limits reported as follows: Fuel Type Figure GNF2 6.1-1a GEl4 6.1-1b For single loop operation (SLO) a multiplier of 0.83 [Reference 3.1.1, page 58] is applied to the APLHGR limits for all fuel types. 7.0 MINIMUM CRITICAL POWER RATIO (MCPR) Per Technical Specification 3.2.2, the MCPR values shall be equal to or greater than the operating limit. The operating limit is the maximum of the flow-dependent minimum critical power ratio (MCPRF) and the power-dependent minimum critical power ratio (MCPRp). MCPRF and MCPRp limits are provided in Sections 7.1 and 7.2 below. These limits address the different fuel types, exposure ranges and application conditions. For single recirculation loop operation (SLO), the MCPR limit is increased by 0.02 [Reference 3.1.1, page 37] to address the difference in the safety limit MCPR reported in Technical Specification 2.1.1.2. 7.1 Flow-Dependent Minimum Critical Power Ratio (MCPRF) Values: The MCPRF curves are from Reference 3.1.1, Appendix D and are found in the following figures: Application Exposure Condition(s) Fuel Type(s) Range Figure 1,2,3 GNF2 & GEl4 BOC-EOC 7.1-1 4,5,6,7 GNF2&GEl4 BOC-EOC 7.1-2 7.2 Power-Dependent Minimum Critical Power Ratio (MCPRp) Values: PAGE 7 OF 81 LAR-2013-03

For example EOC values may be used instead of the MOC values. 8.0 LINEAR HEAT GENERATION RATE (LHGR) Per Technical Specification 3.2.3, the LHGR values for any rod at any axial location shall not exceed the exposure-dependent limits multiplied by the smaller of either the power-dependent or flow-dependent LHGR factors. For single loop operation (SLO) a multiplier of 0.83 [Reference 3.1.1, page 58] is applied to the LHGR limits for all fuel types. For two recirculation loop and single recirculation loop operation the LHGR multiplier is as follows: For two recirculation loop operation: LHGRFAC = MIN(LHGRFACp, LHGRFACF) For single loop operation: LHGRFAC = MIN(LHGRFACp, LHGRFACF, 0.83) 8.1 Exposure-Dependent Linear Heat Generation Rate (LHGR) Values: GNF2 and GEi4 exposure-dependent LHGR values are considered GNF proprietary and will not be contained in the COLR. The GNF2 and GEi4 LHGR values may be found in Reference 3.1.2. 8.2 Flow-Dependent Linear Heat Generation Rate Factors (LHGRFACF) Values: There is one set flow-dependent LHGRFAC values. It is applicable to all application conditions and fuel types, from are from Reference 3. 1. 1, Appendix D and is contained in Figure 8.2-1. PAGE 8 OF 81 LAR-2013-03

For example EOC values may be used instead of the MOC values. 9.0 STABILITY The following Technical Specifications / Technical Requirements contain stability related requirements: TS 3.2.4, Fraction of Core Boiling Boundary (FCBB) TS 3.3.1.1, RPS Instrumentation (RPS) TS 3.3.1.3, Periodic Based Detection System (PBDS) TR 3.3.1.1, RPS Instrumentation (RPS) TR 3.3.2.1, Control Rod Block Instrumentation 9.1 Stability Region Boundaries and Setpoints This section contains region boundaries, setpoints and other stability related requirements. region boundaries and setpoints are as follows The stability Description Figure Monitored Region Boundary (Case 1) 9.1-1 Monitored Region Boundary (Case 2) 9.1-2 APRM Flow Biased Simulated Thermal Power - High Scram Setpoints and Restricted 9.1-3 Region Boundary (Two Recirculation Loop Operation - Case 1) APRM Flow Biased Simulated Thermal Power-High Scram Setpoints and Restricted 9.1-4 Region Boundary (Two Recirculation Loop Operation - Case 2) APRM Flow Biased Simulated Thermal Power-High Scram Setpoints and Restricted 9.1-5 Region Boundary (Single Recirculation Loop Operation - Case 1) APRM Flow Biased Simulated Thermal Power - High Scram Setpoints and Restricted 9.1-6 Region Boundary (Single Recirculation Loop Operation - Case 2) APRM Flow Biased Neutron Flux - High Rod-Block Setpoints (Two Recirculation Loop 9.1-7 PAGE 9 OF 81 LAR-2013-03

These are described as follows: Case 1 - Normal Feedwater Heating Operation or Low Reactor Power: TFW (at rated)- " T"DESIGN (at rated)- 50° F, and rated equivalent at off-rated reactor conditions OR P:_< 30% Case 2 - Reduced Feedwater Heating Operation: TFW (at rated) < TDESIGN (at rated) - 500 F AND P>30% The APRM Flow Biased Simulated Thermal Power - High scram setpoint and Restricted Region Boundary, and APRM Flow Biased Neutron Flux - High Rod-Block Setpoints are given in terms of aligned drive flow. The aligned drive flow is calculated from the input drive flow using the following relationship: 101.209 x A40 31.028 x A100 + 70.181 x W5 WD = 70.181 (A100 A40) Where: W5 = FCTR card input drive flow in percent rated, WD = Aligned drive flow in percent rated, A 40 Low flow drive flow alignment setting, and A100 = High flow drive flow alignment setting. 9.2 APRM Flow Biased Simulated Thermal Power-High Time Constant (SR 3.3.1.1.14) The simulated thermal power time constant is 6 +/- 0.6 seconds (Reference 3.1.3). Thus the maximum simulated thermal power time constant for use in meeting the surveillance requirement is 6.6 seconds. PAGE 10 OF 81 LAR-2013-03
