SUMMARY

This report provides the following cycle-specific parameter limits for Peach Bottom Atomic Power Station Unit 2 Cycle 12 (Reload 11);

. Maximum Average Planar Linear Heat Generation Rate (MAPLHGR)

. ARTS MAPLHGR thermal limit multipliers e Single Loop Operation (SLO) MAPLHGR multipliers L

Minimum Critical Power Ratio (MCPR) e ARTS MCPR thermal limit adjustments and multipliers

. Single Loop Operation (SLO) MCPR adjustment e Rod Block Monitor (RBM) Analytical Limits, Allowable Values and MCPR Limits e

Linear Heat Generation Rate (LHGR) .

.- Turbine Bypass Valve Parameters These values have' been determined using NRC-approved methodology and are established such that all applicab!e limits of the plant safety analysis are met.

This report provides the means for calculating the Operating Limit MCPR and MAPLHGR thermal limits for the

. following conditions:

All points in the operating region of the power / flow map including Maximum Extended Load Line Limit

. (MELLL) down to 81% of rated core flow during full power (3458 MWt) operation e increased Core Flow (ICF), up to 110% of rated core flow i

e End-of-Cycle Power Coastdown to a minimum power level of 40%

e Feedwater Heaters Out of Service (FWHOOS) to 55' F temperature reduction Final Feedwater. Temperature Reduction (FWTR) between End-of-Rated (EOR) and End-of-Cycle (EOC) to 80* F temperature reduction The Allowable Values, documented in Reference 21. for feedwater temperature as a function of thermal power for both FWHOOS and FWTR are specified in the appropriate Peach Bottom procedures.

Note that the term 'l EOR" refers to the cycle exposure .at which operation at " rated conditions" is no longer-!

possible (i.e., the' cycle exposure at which cycle extension begins) based on the EOR point as documented in the' !

. current revision of the Cycle Management Report.

i Preparation of this report was performed in accordance with PECO Energy Fuel and Services Division Procedure '

t FM-300 TReload Core Licensing". This report is submitted in accordance with Technical Specification 5.6.5 of Reference (1) 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 2 Cycle 12. <

. ]AEkHGR LIMITS The bwnding MAPLHGR limits (kW/ft) for each fuel type are provided in Figures 1 through 4. The~ bounding MAPLHGR limits are the lowest kW/ft limits of the fuel lattices (excluding natural uranium) which comprise a given fuel type as a function of' average planar exposure. - The MAPLHGR figures are used when hand calculations are required as specified in Reference (4). 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 to be in compliance with Technical Specification 3.2.1. These MAPLHGR limit 2 are specified in References (2), (3),-(7) and (20) and the process computer databank. No reduction in the.

standard MAPLHGR limits is required under ARTS during_ single loop operation (SLO MAPLHGR multiplier =

1.0). The ARTS-based MAPLHGR power-dependent multipliers (MAPFAC(P)) are provided in Figures 5,6 and g 7J Figure 5 is-valid for.seven or more (of nine) Turbine Bypass Valves (TBVs) In-Service and temperature reduction of 55' F for FWTR operation._ Figure 6 is valid for seven or more (of nine) Turbine Bypass Valves (TBVs) In-Service and temperature reduction of 80' F for FWTR operation. Figure 7 is valid for three or more (of nine) TBVs Out-of-Service (OOS) and FWTR operation of 80* F. The flow-dependent multipliers (MAPFAC(F))

are provided in Figures 8 and 9 as a function of the number of recirculation loops in operation only. The power-and flow-dependent MAPLHGR multipliers were obtained from References (5), (12), (16), (19), (23), and (24).

MCPR LIMITS The Operating Limit MCPR (OLMCPR) for use in Technical Specification 3.2.2 for each fuel type is provided in Table 1. These values are determined by the cycle-specific fuel reload analyses in Reference (2). The OLMCPR is increased by 0.02 when operating in SLO (due to the safety limit increase). The Safety Limit MCPRs are

, documented in Section 2.1.1.2 of Reference (1).  ;

h Control rod scram time verification is required as per Technical Specification 3.1.4, " Control Rod Scram Times". l 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 i 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).

Separate MCPR values are presented herein (Table 1) for the following domains:

o Core Flow s 100% of Rated, No FWHOOS/FWTR, TBVs In-Service (seven or more in-service) o Core Flow > 100% of Rated, with or without FWHOOS/FWTR, TBVs In-Service o Core Flow 5100% of Rated, with FWHOOS or FWTR, TBVs in-Service o 'TBVs Out-of-Service (three or more out-of-service) with al! other domains h The OLMCPR values are documented in References (2), (19), and (25) for the GE11 and GE13 fuel designs.

The_ ARTS-based power-dependent MCPR limits, OLMCPR(P), for use in Technical Specification 3.2.2 are

-provided in Figures 10c 11, and 12, Figure 10 is valid for seven or more TBVs in-Service and temperature

' reduction of 55' F for FWTR operation. Figure 11 is valid for seven or more (of nine) TBVs In-Service and temperature. reduction _ of 80' F for FWTR operation. Figure 12 is valid for three or more TBVOOS and temperature reduction *of 80* F for FWTR operation. The flow-dependent MCPR limits, OLMCPR(F), are provided in Figure 13. The OLMCPR(P) values below the turbine scram bypass power are documented in

Reference (19) and'(24). OLMCPR(P, F) curves were obtained from References (5), (16), (17), (19), (23), and .

'VERALL GOVERNING MCPR AND MAPLHGR LIMITS

,4RTS provides for power- and flow-dependent thermal limit adjustments and multipliers which allow for a ,

more reliable administration of the MCPR and MAPLHGR thermal limits. At any given power / flow (P/F) state, I all four limits are to be determined: MAPFAC(P), MAPFAC(F), OLMCPR(P), and OLMCPR(F) from Figures 5 l' through 13, inclusive. The most limiting MCPR and the most limiting MAPLHGR [ maximum of O and OLMCPR(F) and minimum of MAPLHGR(P) and MAPLHGR(F)] for a given (P,F) condition will be the governing limits. The OLMCPR for each fuel type is determined by the cycle-specific fuel reload analyses in Reference (2). Rated MAPLHGR values are a composite of results obtained from bundle-specific thermal-mechanical and emergency core cooling system analyses. Supporting documentation for the ARTS-based j limits is provided in References (5), (6), (12), (16), (17), (197, (23), (24) and (25).

. ROD BLOCK MONITOR SETPOINTS I The RBM power-biased Analytical Limits, Allowable Values and MCPR Limits for use in Technical Specification 3.3.2.1 are provided in Tables 2 and 3 per Reference (5) with supporting documentation in References (2), (8), (14), (15) and (18). Table 2 must be utilized from Beginning-of-Cycle (BOC) to the End-of-Rated (EOR) - 2000 mwd /ST statepoint. Either Table 2 or Table 3 may be used from EOR - 2000 1 mwd /ST to End of-Cycle (EOC).  !

. LINEAR HEAT GENERATION RATES

-The beginning of life (maximum) LHGR values for each fuel type for use in Technical Specification 3.2.3 are provided in Table 4. Conservative LHGR values as a function of fuel exposure are provided in the process-omputer data bank. LHGR values are documented in References (4) and (13).

STEAM BYPASS SYSTEM OPERABILITY The operability requirements for the steam bypass system are governed by Technical Specification 3.7.6 and are further discussed in Reference (10). If the requirements cannot be met, the appropriate power / flow-l dependent limits for TBVOOS must be used (Table 1 with Figures 7 and 12). The minimum number of bypass valves to maintain system operability is seven as per References (9) and (10) and Table 5. Table 5 also includes other Turbine Bypass Valve parameters.- l REFERENCES
