SUMMARY

This report provides Cycle 15 values for the following Technical Specifications:

1. AVERAGE PLANAR LINEAR HEAT GENERATION RATE (APLHGR) limuits,
2. MINIMUM CRITICAL POWER RATIO (MCPR) limits,
3. LINEAR HEAT GENERATION RATE (LHGR) limits,
4. FRACTION OF CORE BOILING BOUJNDARY (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 AREVA are listed in the section t'itled Analytical Methods Documents.

This report also provides Cycle 15 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.

The Cycle 15 COLR supports power operation with FHOOS, FFWTR, PROOS, SLO, EOC-RPT INOPERABLE and Loop Manual Operation. In addition to the specific requirements listed in the Sections 3.2.1 to 3.2.4, the APLHGR, MCPRp and LHGR-p limits as shown in Appendix A shall be used for the applicable modes of operation. For Loop Manual Operation, the MCPR-f as shown in Appe ndix A shall be used.

The reload analyses were performed in accordance with AREVA methodology and its applicability to Cycle 15 was confirmed by Reference 1.

'Note that for Figures 13 to 20, 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 4 of43 RBS CYCLE 15 COLR Revision 0 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.

The limiting APLHGR (sometimes referred to as Maximum APLHGR, or MAPLHGR) as 'a function of AVERAGE PLANAR EXPOSURE is given in Figure 2. They were'determined with the AREVA methodology (Reference 1).

Core location by fuel type is provided in Figure 1 and is the reference core loading pattern in Reference 1.

Page 6 of43 RBS CYCLE 15 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) and power dependent MCPR (MCPRp) (Reference 1) are shown in Figure 4, 5, 6 and 7, respectively. Figure 27 is used in lieu of Figure 4 when the Reactor Recirculat ion 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 AREVA methodology as described in Reference 1 and are consistent with a Safety Limit MCPR from Technical Specification 2.0.

Page 7 of43 RBS CYCLE 15 COLR Revision 0 TECHNICAL SPECIFICATION 3.2.3 POWER DISTRIBUTION LIMITS LINEAR HEAT GENERATION RATE (LHGR)

The limiting LHGR value for ATRIUM- 1 as a function of PELLET EXPOSURE is given in Figure 3. Core location by fuel type is provided in Figure 1 and is the reference core loading pattern in reference 1. Thermal power and core flow dependent multipliers for ATRIUM- 10 are provided i'nFigures 8, 9 and Figure 10, 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 36 of 43 RBS CYCLE 15 COLR Revision 0 APPENDIX A OPERATING LIMITS FOR EQUIPMENT OUT OF SERVICE OR LOOP MANUAL MODE The operating limits listed in this appendix shall be used as indicated when operating in any of the following conditions:

- Feedwater Heater Out of Service (FHOOS)

- Pressure, Regulator Out of Service (PROOS) (2)

- Reactor Recirculation System in Loop Manual control.

- End of Cycle Recirculation Pump Trip (EOC-RPT) Inoporable '

- Single-Loop Operation (SLO)

SPower dependent MCPR and LHGR limits are presented in Figures 21, 22 and 23. Flow dependent LHGR and MCPR limits are presented in Figures 10, 4 for ioop auto and 10, 27 for ioop manual.

(2) Power dependent MCPR and LHGR limits are presented in Figures 24, 25, and 26. Flow dependent LHGR and MCPR limits are presented in Figures 10, 4 for ioop auto;' and 10, 27 for loop manual.

()The power dependent MCPRp for normal operation (Figures 5, 6.and 7) and equipment out of services (EOOS) described in (1) and (2) above shall be increased by 0.02 for SLO. The limits of APLHGR (Figure 2) shall be reduced to a value of 0.95 times the two recirculation loop operation limit when in single loop operation (Reference 1).

Note: Power dependent MCPR and LHGR limits for an operating mode at EEEOC exposure point may be used to bound all cycle exposures
