This report provides cycle-specific Operating Limit MCPR, LHGR, MAPLHGR thermal limits, and related information for the following conditions:

" All points in the operating region of the power/flow map including Maximum Extended Load Line Limit (MELLL) down to 82.8% of rated core flow during full power (3514 MWt) operation

" Increased Core Flow (ICF), up to 110% of rated core flow

• Feedwater Heaters Out of Service (FWHOOS) to 55 'F temperature reduction

• Final Feedwater Temperature Reduction (FFWTR) between End-of-Rated (EOR) and End-of-Cycle (EOC) to 90 'F temperature reduction maintaining < 100% load line

• Asymmetric Feedwater Temperature Operation (AFTO)

ARTS provides for power-and flow-dependent thermal limit adjustments and multipliers that allow for a more reliable administration of the MCPR and LHGR thermal limits. The OLMCPR is determined by the cycle-specific reload analyses in Reference 2. Rated LHGR values are obtained from the bundle-specific thermal-mechanical analysis. Supporting documentation for the ARTS-based limits is provided in Reference 2. The allowable values for feedwater temperature as a function of thermal power for both FWHOOS and FFWTR are specified in the appropriate Peach Bottom procedures and Reference 2.

Also note that the following description of MAPLHGR, LHGR and MCPR limits pertain to NON - AFTO conditions. A separate description of AFTO limits and their associated ARTS tables is located in Section 10.

Preparation of this report was performed in accordance with Exelon Nuclear procedures. This report is submitted in accordance with Technical Specification 5.6.5 of Reference I and contains all thermal limit parameters related to the implementation of the ARTS Improvement Program and Maximum Extended Load Line Limit Analyses (ARTS/MELLLA) for Peach Bottom Unit 3 Cycle 19.

The MAPLHGR limits are provided for a given fuel type as a function of average planar exposure. The MAPLHGR tables are used when hand calculations are required. All MAPLHGR values for each fuel type as a function of axial location and average planar exposure shall be less than or equal to the applicable MAPLHGR limits for the respective fuel and lattice types. These MAPLHGR limits are specified in Reference 2 and are loaded in the process computer databank. The SLO MAPLHGR reduction factor is applied as shown in Table 3-3 per Reference 2. This value is applicable to the GE14 and GNF2 product lines. The impact of AFTO on MAPLHGR is addressed in Section 10. MAPFAC(P) and MAPFAC(F) are 1.0 for all conditions.

Table 4-1 is valid for all fuel types in the core. OLMCPRs are the maximum values obtained from analysis of pressurization events, non-pressurization events, and Option III stability evaluation. MCPR values are determined by the cycle-specific fuel reload analyses in Reference 2. Control rod scram time verification is required per Technical Specification 3.1.4, "Control Rod Scram Times." Tau, a measure of scram time performance to notch position 36 throughout the cycle, is determined based on the cumulative scram time test results. The calculation of Tau shall be performed in accordance with site procedures.

Linear interpolation shall be used to calculate the OLMCPR value if Tau is between 0.0 (Tau Option B) and 1.0 (Tau Option A), per Methodology Reference 1.

Separate OLMCPR values are presented in Table 4-I for the following domains:

" TBVs In-Service (seven or more in-service) and RPT In-Service, maximum FWTR of 90'F "TBVs Out-of-Service (six or less in-service) and RPT In-Service, maximum FWTR of 90'F "TBVs In-Service (seven or more in-service) and RPT Out-of-Service, maximum FWTR of 90'F The ARTS-based power-dependent MCPR limits and multipliers are provided in Table 4-2. Table 4-2 is valid for a maximum temperature reduction of 90 'F for FWTR operation. The flow-dependent MCPR limits are provided in Table 4-3. Flow-dependent MCPR limits for single loop operation (SLO) are provided in Table 4-4. Tables 4-2, 4-3, and 4-4 are valid for all fuel types in the core. The impact of AFTO on MCPR is addressed in Section 10.

If the requirements cannot be met, the appropriate power and flow dependent limits for EOC Recirculation Pump Trip (RPTOOS) must be used. Additionally the OLMCPR for RPTOOS must be applied.

A total RPT response time of 0.175 seconds is assumed in the safety analysis for both trips and is defined as the time from the turbine valves (TCV or TSV) start to close until complete arc suppression of the EOC-RPT circuit breakers. Reference 8 provides the basis for the RPT response time.

Asymmetric feedwater heating (resulting from removing a heater string, or individual feedwater heaters, from operation) is the result of the specific configuration of the feedwater lines at Peach Bottom. A reduction in heating in either the 'A' or the 'C' heater strings will result in a temperature mismatch between the feedwater flows entering the opposite sides of the reactor vessel. This temperature mismatch may result in errors in the thermal limit values calculated by the core monitoring system. Thermal limit values for all conditions and events are impacted by these errors. Asymmetric feedwater temperature operation (AFTO) is defined as operation in a feedwater heater/string configuration that results in a specified threshold difference as described in Reference 11.

The threshold values are incorporated in the station procedures that govern AFTO.

LHGR LIMITS The ARTS-based LHGR power-dependent multipliers for AFTO operation are provided in Tables 10-2, 10-3, and 10-4. The flow-dependent multipliers for AFTO are provided in Tables 10-5, 10-6, and 10-7 as a function of the number of recirculation loops in operation only. The power and flow-dependent LHGR multipliers were obtained from Reference 2 and were adjusted with the appropriate penalties displayed in Table 10-1 per Reference 11. The SLO multiplier and the AFTO multiplier must be simultaneously applied. The maximum feedwater temperature difference allowed without a thermal limit penalty is 20 OF. Once the temperature difference exceeds 20 OF, the graduated penalties from Table 10-1 are applied to the thermal limits. Tables 10-2 through 10-7 are applicable for all fuel types in the core.

Per Table 10-1, a 2% penalty was applied to MCPR values for a feedwater temperature difference greater than 30 OF. The ARTS-based power-dependent MCPR limits for use during AFTO conditions are provided in Table 10-9. The flow-dependent MCPR limits for AFTO are provided in Table 10-10. Flow-dependent MCPR limits for AFTO and SLO are provided in Table 10-

11. The power and flow-dependent OLMCPR curves were obtained from Reference 2 and were adjusted with a 2% penalty for feedwater temperature difference greater than 30 OF as displayed in Table 10-1 per Reference 11.

No MCPR penalties are required for asymmetric temperature differentials less than or equal to 30 °F. Tables 10-8 through 10-11 are valid for all fuel types in the core.

OLMCPR is set to reflect two loop operation OPRM amplitude setpoint of 1.12.

(3) For single loop operation, the OLMCPR is 0.03 greater than the two loop limit (with the exception of the OPRM based OLMCPR, which remains the same). However, a minimum value of 1.44 is required to obtain an OLMCPR set by the Single Loop Operation Recirculation Pump Seizure event (Reference 2).

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 Peach Bottom Unit 3 -for Cycle 19. 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.
