Exelon Nuclear - Nuclear Fuels Doc ID: COLR Limerick 1, Rev. 9 Core Operating Limits Report Non-Proprietary Information Submitted in Accordance with 10 CFR 2.390 2.0 General Information This report provides the following cycle-specific parameter limits for Limerick Generating Station Unit I Cycle 15:

  • Maximum Average Planar Linear Heat Generation Rate (MAPLHGR)
  • Minimum Critical Power Ratio (MCPR)
  • Single Loop Operation (SLO) MCPR adjustment
  • ARTS MCPR thermal limit adjustments and multipliers (MCPR(P) or MCPR(F))
  • ARTS LHGR thermal limit multipliers (LHGRFAC(P) or LHGRFAC(F))
  • Rod Block Monitor (RBM) setpoints
  • MAPLHGR single loop operation reduction factor
  • LHGR single loop operation reduction factor
  • Linear Heat Generation Rate (LHGR)
  • Turbine Bypass Valve parameters
  • Reactor Coolant System Recirculation Flow Upscale Trips
  • Oscillation Power Range Monitor Period Based Detection Algorithm (OPRM PBDA) Trip Setpoints This report is prepared in accordance with Technical Specification 6.9.1.9 of Reference 1. Power and flow dependent limits are listed for various power and flow levels. Linear interpolation is to be used to find intermediate values.

The data presented in this report is valid for all licensed operating domains on the operating map, including:

  • Maximum Extended Load Line Limit down to the minimum licensed core flow during full power operation
  • Increased Core Flow (ICF) up to 110% of rated core flow
  • Final Feedwater Temperature Reduction (FFWTR) up to 105.0°F during cycle extension operation
  • Feedwater Heater Out of Service (FWHOOS) up to 60.0°F feedwater temperature reduction at any time during the cycle prior to cycle extension.

Further information on the cycle-specific analyses for Limerick Unit I Cycle 15 and the associated operating domains discussed above is available in Reference 2. Page 6 of 57

Exelon Nuclear - Nuclear Fuels Doc ID: COLR Limerick 1, Rev. 9 Core Operating Limits Report Non-Proprietary Information Submitted in Accordance with 10 CFR 2.390 3.0 MAPLHGR Limits 3.1 Technical Specification Section 3.2.1 3.2 Description The limiting MAPLHGR value for the most limiting lattice (excluding natural uranium) of each fuel type as a function of average planar exposure is given in Tables 3-1 and 3-2. For single loop operation, a reduction factor is used, which is shown in Table 3-3. The power and flow dependent multipliers for MAPLHGR have been removed and replaced with LHGRFAC(P) and LHGRFAC(F); therefore, MAPFAC(P) and MAPFAC(F) are equal to 1.0 for all power and flow conditions (Reference 2). LHGRFAC(P) and LHGRFAC(F) are addressed in Section 5.0. Table 3-1 MAPLHGR Versus Average Planar Exposure - GE14 (Reference 2) Average Planar Exposure MAPLHGR Limit (GWD/ST) (kW/ft) 0.0 12.82 19.13 12.82 57.61 8.00 63.50 5.00 Table 3-2 MAPLHGR Versus Average Planar Exposure - GNF2 (Reference 2) Average Planar Exposure MAPLHGR Limit (GWD/ST) (kW/ft) 0.0 13.78 17.52 13.78 60.78 7.50 63.50 6.69 Table 3-3 MAPLHGR SLO Reduction Factor - All Fuel Types (Reference 2) SLO Reduction Factor 1 0.80 Page 7 of 57

Exelon Nuclear - Nuclear Fuels Doc ID: COLR Limerick 1, Rev. 9 Core Operating Limits Report Non-Proprietary Information Submitted in Accordance with 10 CFR 2.390 4.0 MCPR Limits 4.1 Technical Specification Section 3.2.3 4.2 Description Tables 4- 1 and 4-2 are derived from Reference 2 and are valid for all Cycle 15 operating domains. Table 4-1 is valid for GE14 fuel and Table 4-2 is valid for GNF2 fuel. Tables 4-1 and 4-2 include treatment of these MCPR limits for all conditions listed in Section 9.0, Modes of Operation. Limerick Unit 1 Cycle 15 was analyzed with no mid-cycle MCPR breakpoint. ARTS provides for power and flow dependent thermal limit adjustments and multipliers, which allow for a more reliable administration of the MCPR thermal limit. The flow dependent adjustment MCPR(F) is sufficiently generic to apply to all fuel types and operating domains. The power dependent adjustment MCPR(P) is independent of recirculation pump trip operability. MCPR(P) and MCPR(F) are independent of Scram Time Option. In addition, there are six sets of power dependent MCPR multipliers (Kp) for use with the BASE, TBVOOS, RPTOOS, DLO and SLO conditions. The PLUOOS condition is included in the BASE MCPR(P) and MCPR(F) limits and Kp multipliers and is bounded by the TBVOOS limits and multipliers; therefore, no additional adjustments are required for PLUOOS in those operating conditions. The PLUOOS condition has not been analyzed concurrent with the RPTOOS operating condition. Operation in the PLUOOS condition concurrent with the RPTOOS condition requires core thermal power < 55% of rated (Reference 3). Section 7.0 contains the conditions for Turbine Bypass Valve Operability. MCPR(P) and MCPR(F) adjustments for all fuel types are provided in Table 4-3 and 4-4, respectively. The OLMCPR is determined for a given power and flow condition by evaluating the power dependent MCPR and the flow dependent MCPR and selecting the greater of the two. Page 8 of 57

However, a minimum value of 1.46 for GE14 fuel and 1.58 for GNF2 fuel is required to obtain an OLMCPR limit set by the Single Loop Operation Recirculation Pump Seizure Event (Reference 2).

Exelon Nuclear - Nuclear Fuels Doc ID: COLR Limerick 1, Rev. 9 Core Operating Limits Report Non-Proprietary Information Submitted in Accordance with 10 CFR 2.390 5.0 LHGR Limits 5.1 Technical Specification Section 3.2.4 5.2 Description The LHGR limit is the product of the exposure dependent LHGR limit (from Table 5-1 for U02 fuel rods and Table 5-2 for Gadolinia fuel rods) and the minimum of: the power dependent LHGR Factor, LHGRFAC(P), and the flow dependent LHGR Factor, LHGRFAC(F). For single loop operation, a reduction factor is used, which is shown in Table 5-3 and applied in Table 5-5. No further Single Loop Operating reduction factors need to be applied to the values in Tables 5-4 and 5-5. ARTS provides for power and flow dependent thermal limit multipliers, which allow for a more reliable administration of the LHGR thermal limits. There are two sets of flow dependent LHGR multipliers for dual-loop and single-loop operation. In addition, there are six sets of power dependent LHGR multipliers for use with the BASE, TBVOOS, RPTOOS, DLO and SLO conditions. The PLUOOS condition is included in the BASE LHGRFAC(P) and LHGRFAC(F) multipliers and is bounded by the TBVOOS multipliers; therefore, no additional adjustments are required for PLUOOS in those operating conditions. The PLUOOS condition has not been analyzed concurrent with the RPTOOS operating condition. Operation in the PLUOOS condition concurrent with the RPTOOS condition requires core thermal power 

           < 55% of rated (Reference 3). Tables 5-4 and 5-5 for LHGRFAC(P) and LHGRFAC(F),

respectively, are applicable to both GE14 and GNF2 fuel types. Section 7.0 contains the conditions for Turbine Bypass Valve Operability. Linear interpolation should be used for points not listed in Appendix A. Thermal limit monitoring must be performed with the more limiting LHGR limit resulting from the power and flow biased calculation. The LHGRFAC(P) curves are independent of recirculation pump trip operability.

Technical Specification 3.3.6 states control rod block instrumentation channels shall be OPERABLE with their trip setpoints consistent with the values shown in the Trip Setpoint column of Technical Specification Table 3.3.6-2. The trip setpoints/allowable values and applicable RBM signal filter time constant data are shown in Table 6-1. The Reactor Coolant System Recirculation Flow Upscale Trip is shown in Table 6-2. These setpoints are set high enough to allow full utilization of the enhanced ICF domain up to 110% of rated core flow.

1. Introduction and Summary This report, which supplements the Supplemental Reload Licensing Report, contains thermal-mechanical linear heat generation rate (LHGR) limits for the GNF-A fuel designs to be loaded into Limerick 1 for Cycle 15. These LHGR limits are obtained from thermal-mechanical considerations only. Approved GNF-A calculation models documented in Reference 1 were used in performing this analysis.

LHGR limits as a function of exposure for each bundle of the core design are given in Appendix A. The LHGR values provided in Appendix A provide upper and lower exposure dependent LHGR boundaries which envelope the actual gadolinia dependent LHGR limits. The LHGRs reported have been rounded to two places past the decimal. Appendix B contains a description of the fuel bundles. Table B-1 contains a summary of bundle-specific information, and the figures provide the enrichment distribution and gadolinium distribution for the fuel bundles included in this appendix. These bundles have been approved for use under the fuel licensing acceptance criteria of Reference 1. Page 3 COLR Page 20 of 57
