SUMMARY

This report provides Cycle 13 values for the following Technical Specifications:

1. AVERAGE PLANAR LINEAR HEAT GENERATION RATE (APLHGR) limits,

2. MINIMUM CRITICAL POWER RATIO (MCPR) limits,

3. LINEAR HEAT GENERATION RATE (LHGR) limits,

4. FRACTION OF CORE BOILING BOUNDARY (FCBB),

5. REACTOR PROTECTION SYSTEM (RPS) APRM Flow Biased Simulated Thermal Power - High Allowable Values,

6. REACTOR PROTECTION SYSTEM (RPS) APRM Flow Biased Simulated Thermal Power time constant.

7. PERIOD BASED DETECTION SYSTEM (PBDS) region boundaries.

Technical Specification section 5.6.5 requires these values be determined using NRC-approved methodology and are established such that all applicable limits of the plant safety analysis are met. The references for the pertinent methodology used by FANP are listed in the section titled Analytical Methods Documents.

This report also provides Cycle 13 values for the following Technical Requirements:

1. REACTOR PROTECTION SYSTEM (RPS) APRM Flow Biased Neutron Flux Power - High Allowable Values and Nominal Trip Setpoints',

2. CONTROL ROD BLOCK INSTRUMENTATION APRM Flow Biased Neutron Flux High limits.

In some cases limits in the COLR differ from the limits in the core monitoring system.

This is sometimes due to limitations in the core monitoring system to model the actual limits, in which case the core monitoring limits may be more conservative than the COLR limit at the given conditions. In other cases the limits in the COLR are presented in less detail than in the core monitoring system.

The Cycle 13 COLR supports power operation with FHOOS, FFWTR, PROOS, SLO and Loop Manual Operation. In addition to the specific requirements listed in the Sections 3.2.1 to 3.2.4, the MCPRp and LHGRFAC-p limits as shown in Appendix A shall be used for the applicable modes of operation. For Loop Manual Operation, the MCPRf as shown in Appendix A shall be used. Figures 42 and 43 are applicable to FHOOS or PROOS but not for simultaneous FHOOS and PROOS.

The reload analyses were performed in accordance with FANP methodology and its applicability to Cycle 13 was confirmed by Reference 5.

'Note that for Figures 30 to 37, the Nominal Setpoints should be used for indicating the entry into a particular stability region as allowed and appropriate actions be taken prior to the entry

Page 5 of 63 RBS CYCLE 13 COLR Revision 0 TECHNICAL SPECIFICATION 3.2.1 POWER DISTRIBUTION LIMITS AVERAGE PLANAR LINEAR HEAT GENERATION RATE (APLHGR)

The limiting APLHGR (sometimes referred to as Maximum APLHGR, or MAPLHGR) value for the most limiting lattice (excluding natural uranium) of each fuel type as a function of AVERAGE PLANAR EXPOSURE is given in Figures 2 through 7. Two sets of MAPLHGR are provided herein for ATRIUM-10 and GE-I 1. The GE-I set was determined with the SAFER/GESTR LOCA and GESTR-Mechanical methodology described in GESTAR-II (Reference 1).

The ATRIUM-10 set was determined with the FANP methodology (Reference 5).

The ATRIUM-10 APLHGR is further divided into two subsets: the reconstituted (marked by the designator KAN listed in the relevant figure), and the regular ATRIUM-l0. Core location by fuel type is provided in Figure 1 and is the reference core loading pattern in reference 5. The limits of these figures shall be reduced to a value of 0.79 and 0.83 times the two recirculation loop operation limit when in single loop operation for GE-il and ATRIUM-10, respectively (Reference 5). Thermal power and core flow dependent multipliers are provided.

The value of the exposure dependent limit is reduced by the value of the multiplier at a given offrated power or flow condition. The multipliers for single loop operation are shown in Appendix A.

The APLHGR limits for GE-i1 in the core monitoring system are in more detail than the limits that appear in the COLR due to their proprietary nature. The core monitoring system has APLHGR limits for each lattice in a bundle rather than listing only the most limiting value for the entire bundle. References 4 and 5 list the core monitoring system limits.

Page 6 of 63 RBS CYCLE 13 COLR Revision 0 TECHNICAL SPECIFICATION 3.2.2 POWER DISTRIBUTION LIMITS MINIMUM CRITICAL POWER RATIO (MCPR)

The MCPR limits for use in Technical Specification 3.2.2 for flow dependent MCPR (MCPRF) (Reference 5), power dependent MCPR (MCPRp) (Reference 5) are shown in Figures 13 and 14 and Figures 17 to 24, respectively. Figures 46 and 47 are used in lieu of Figures 13 and 14 when the Reactor Recirculation System is operating in Loop Manual Mode. The most limiting value from the applicable MCPRf and MCPRp figures is the operating limit. These values were determined with FANP methodology as described in Reference 5 and are consistent with a Safety Limit MCPR from Technical Specification 2.0.

At a power level greater than 40%, the power dependent MCPRp (Figures 23 and 24) shall be increased by 0.02 for Single Loop Operation. At a power lower than 40%, the most limiting MCPRp value is the operating limit, and it shall be increased by 0.02 for Single Loop Operation.

Page 7 of 63 RBS CYCLE 13 COLR Revision 0 TECHNICAL SPECIFICATION 3.2.3 POWER DISTRIBUTION LIMITS LINEAR HEAT GENERATION RATE (LHGR)

The limiting LHGR value for ATRIUM-10 and for the most limiting lattice of each GE-I 1 fuel type as a function of AVERAGE PLANAR EXPOSURE is given in Figures 8 through 12. Core location by fuel type is provided in Figure 1 and is the reference core loading pattern in reference 5. The LHGR limits for GE-11 and ATRIUM-10 in the core monitoring system are in more detail than the limits that appear in the COLR due to proprietary nature (References 9 and 10).

Thermal power and core flow dependent multipliers for ATRIUM-10 and GE-Il are provided in Figures 25, 26 & 27 and Figures 15 & 16, respectively. The value of the exposure dependent limit is reduced by the value of the multiplier at a given offrated power or flow condition.

SUMMARY

This report provides Cycle 13 values for the following Technical Specifications:

1. AVERAGE PLANAR LINEAR HEAT GENERATION RATE (APLHGR) limits,

2. MINIMUM CRITICAL POWER RATIO (MCPR) limits,

3. LINEAR HEAT GENERATION RATE (LHGR) limits,

4. FRACTION OF CORE BOILING BOUNDARY (FCBB),

5. REACTOR PROTECTION SYSTEM (RPS) APRM Flow Biased Simulated Thermal Power - High Allowable Values,

6.

REACTOR PROTECTION SYSTEM (RPS) APRM Flow Biased Simulated Thermal Power time constant.

7.

PERIOD BASED DETECTION SYSTEM (PBDS) region boundaries.

Technical Specification section 5.6.5 requires these values be determined using NRC-approved methodology and are established such that all applicable limits of the plant safety analysis are met. The references for the pertinent methodology used by FANP are listed in the section titled Analytical Methods Documents.

This report also provides Cycle 13 values for the following Technical Requirements:

1. REACTOR PROTECTION SYSTEM (RPS) APRM Flow Biased Neutron Flux Power - High Allowable Values and Nominal Trip Setpoints',

2. CONTROL ROD BLOCK INSTRUMENTATION APRM Flow Biased Neutron Flux High limits.

In some cases limits in the COLR differ from the limits in the core monitoring system.

This is sometimes due to limitations in the core monitoring system to model the actual limits, in which case the core monitoring limits may be more conservative than the COLR limit at the given conditions. In other cases the limits in the COLR are presented in less detail than in the core monitoring system.

The Cycle 13 COLR supports power operation with FHOOS, FFWTR, PROOS, SLO and Loop Manual Operation.

In addition to the specific requirements listed in the Sections 3.2.1 to 3.2.4, the MCPRp and LHGRFAC-p limits as shown in Appendix A shall be used for the applicable modes of operation. For Loop Manual Operation, the MCPRf as shown in Appendix A shall be used. Figures 42 and 43 are applicable to FHOOS or PROOS but not for simultaneous FHOOS and PROOS.

The reload analyses were performed in accordance with FANP methodology and its applicability to Cycle 13 was confirmed by Reference 5.

'Note that for Figures 30 to 37, the Nominal Setpoints should be used for indicating the entry into a particular stability region as allowed and appropriate actions be taken prior to the entry

Page 4of63 RBS CYCLE 13 COLR Revision 1 CONTROL RODS The River Bend core utilizes both GE control rods and ABB CR-82M bottom entry cruciform control rods.

These Control Rod designs are discussed in more detail in Reference 7.

DEFINITIONS MOC - Middle of Cycle (Core Exposure 25,921 MWd/MTU).

EEOC - Extended cycle with Increased Core Flow (Core Exposure 27,341 MWd/MTU).

EEEOC - Extended cycle with Increased Core Flow and Final Feedwater Temperature Reduction (Core Exposure 27,881 MWd/MTU).

FFWTR - Final Feedwater Temperature Reduction.

FHOOS - Feedwater Heater Out of Service.

PROOS - Pressure Regulator Out of Service.

SLO - Single Loop Operation.

FANP - Framnatome ANP KAN - The designator for the reconstituted ATRIUM-1 0 assemblies.

REFERENCE CORE LOADING PATTERN - The Core Loading Pattern Used for Reload Licensing Analysis.

REVISION HISTORY Revision 0 is to provide the thermal limits for Cycle 13 power operation.

Revision I changes the MOC, EOC, EEOC and EEEOC exposure points consistent with Reference 11.

Page 5 of 63 RBS CYCLE 13 COLR Revision I TECHNICAL SPECIFICATION 3.2.1 POWER DISTRIBUTION LIMITS AVERAGE PLANAR LINEAR HEAT GENERATION RATE (APLHGR)

The limiting APLHGR (sometimes referred to as Maximum APLHGR, or MAPLHGR) value for the most limiting lattice (excluding natural uranium) of each fuel type as a function of AVERAGE PLANAR EXPOSURE is given in Figures 2 through 7. Two sets of MAPLHGR are provided herein for ATRIUM-10 and GE-I 1. The GE-1I set was determined with the SAFER/GESTR LOCA and GESTR-Mechanical methodology described in GESTAR-II (Reference 1).

The ATRIUM-1 0 set was determined with the FANP methodology (Reference 5).

The ATRIUM-10 APLHGR is further divided into two subsets: the reconstituted (marked by the designator KAN listed in the relevant figure), and the regular ATRIUM-10. Core location by fuel type is provided in Figure 1 and is the reference core loading pattern in reference 5. The limits of these figures shall be reduced to a value of 0.79 and 0.83 times the two recirculation loop operation limit when in single loop operation for GE-Il and ATRIUM-10, respectively (Reference 5). Thermal power and core flow dependent multipliers are provided.

The value of the exposure dependent limit is reduced by the value of the multiplier at a given offrated power or flow condition. The multipliers for single loop operation are shown in Appendix A.

The APLHGR limits for GE-1I in the core monitoring system are in more detail than the limits that appear in the COLR due to their proprietary nature. The core monitoring system has APLHGR limits for each lattice in a bundle rather than listing only the most limiting value for the entire bundle. References 4 and 5 list the core monitoring system limits.

Page 6 of 63 RBS CYCLE 13 COLR Revision i TECHNICAL SPECIFICATION 3.2.2 POWER DISTRIBUTION LIMITS MINIMUM CRITICAL POWER RATIO (MCPR)

The MCPR limits for use in Technical Specification 3.2.2 for flow dependent MCPR (MCPRF) (Reference 5), power dependent MCPR (MCPRp) (Reference 5) are shown in Figures 13 and 14 and Figures 17 to 24, respectively. Figures 46 and 47 are used in lieu of Figures 13 and 14 when the Reactor Recirculation System is operating in Loop Manual Mode. The most limiting value from the applicable MCPRf and MCPRP figures is the operating limit. These values were determined with FANP methodology as described in Reference 5 and are consistent with a Safety Limit MCPR from Technical Specification 2.0.

At a power level greater than 40%, the power dependent MCPRp (Figures 23 and 24) shall be increased by 0.02 for Single Loop Operation. At a power lower than 40%, the most limiting MCPRp value is the operating limit, and it shall be increased by 0.02 for Single Loop Operation.

Page 7 of 63 RBS CYCLE 13 COLR Revision 1 TECHNICAL SPECIFICATION 3.2.3 POWER DISTRIBUTION LIMITS LINEAR HEAT GENERATION RATE (LHGR)

The limiting LHGR value for ATRIUM-10 and for the most limiting lattice of each GE-1I fuel type as a function of AVERAGE PLANAR EXPOSURE is given in Figures 8 through 12. Core location by fuel type is provided in Figure 1 and is the reference core loading pattern in reference 5. The LHGR limits for GE-I l and ATRIUM-lO in the core monitoring system are in more detail than the limits that appear in the COLR due to proprietary nature (References 9 and 10). Thermal power and core flow dependent multipliers for ATRIUM-10 and GE-i1 are provided in Figures 25, 26 & 27 and Figures 15 & 16, respectively. The value of the exposure dependent limit is reduced by the value of the multiplier at a given offrated power or flow condition.

Page 8 of 63 RBS CYCLE 13 COLR Revision I TECHNICAL SPECIFICATION 3.2.4 POWER DISTRIBUTION LIMITS FRACTION OF CORE BOILING BOUNDARY (FCBB)

Restricted Region Boundary Note: The boundary of the Restricted Region is established by analysis in terms of thermal power and core flow. The Restricted Region boundary is defined by the "non-setup" APRM Flow Biased Simulated Thermal Power - High Control Rod Block Setpoints, which are a function of reactor recirculation drive flow.

The Restricted Region boundaries as a function of aligned drive flow are given in Figures 30 through 33 in terms of aligned drive flow. The aligned drive flow is calculated from the input drive flow using the relationship given in Table 1.

Flow Biased Simulated Thermal Power - High Limits The APRM Flow Biased Simulated Thermal Power - High Scram setpoints as a function of aligned drive flow are given in Figures 30 through 33. The aligned drive flow is calculated from the input drive flow using the relationship given in Table 1.

a. Case I - Normal Feedwater Heating Operation or Low Reactor Power:
