PEco Fuel Managonent Section PEco-CoLR-PD2 R8 PB2R8 Core Operating Limits Report Pago 3, Rev. O IllTRODUCTIOli AND SUMMAfd This report provides the cycle-specific paramotor limits fort Average Planar Lincur Heat Generation Rato (APLHGR); Minimum Critical Power Ratio (MCPR); Flow Adjustment Factor (Kr); Linear Heat Generation Rate (LHGR); and Rod Block Monitor flow biased upscale setpoints for Peach Bottom Atomic Power Station Unit 2, Cycle 9, Roload 8. These values have been determined using NRC-approved methodology and are established such that all applicable limits of the plant safety analysis are met.

This report is submitted in accordance with Technical Specification 6.9.1.e of Reference (1). Preparation of this report was performed in nccordance with PEco Nuclear Group Proceduro NP-11F122.

APLHGR LIMITS The limiting APLHGR value for the most limiting lattice (excluding natural uranium) of each fuel type as a function of AVERAGE PLANAR EXPOSURE is given in Figuros 1 through 8. Figures 1 through 8 are used when hand calculations aro required as specified in Technical Specification 3.5.I. The reduction factors for uso during single recirculation loop operation are shown in Table 1.

MCPR_ LIMITS The MCPR values for use in Technical Specification 3.5.K for each fuel type are given in Figures 9 through 15 and in Tables 2 and 3. Table 2 is used when the requirement of 4.5.K.2.a is met, when this requirement cannot be met the Operating Limit MCPR values as a function of TAU are given in Figuros 9 through 15.

At times when the surveillance requirement of specification 4.5.K.2 is not performed Table 3 is used. The Kr core flow adjustment factor for use in Technical Specification 3.5.K is given in Figure 16.

The MCPR limits to be used during cycle extension (Increased Core Flow (ICF), Final Foodwater Temperature Roduction, and Power Coastdown) following EOC are the EoC-2000 Mwd /st to EOC, Increased Core Flow limits.

e PECO Tuul Management Section PECO-CO LR-PB2 R8 PB2R8 Coro Operating Limits Report Page 4, Rov. O B.OD BLOCK MONITOR SETPOINTS The N value for the RBM flow biased upscale sotpoints for uno in Technical Specification 3.2.C is given in Table 4.

LINEldlJ1 EAT GENERATION RATES The LHGR value for uso in Technical Specification 3.5.J for each fuel typo is given in Table 5.

( OUALIFICATIQN FUEL BUNDLES

'4 The thermal limits for the Advanced Nuclear Fuels and the ABB Atom Inc. Qualification Fuel Bundlos (QFDs) are determined by comparison to the cyclo 9 reload bundle (Fuol Type P80WB320, GE8X8HB) . The results of those comparisons demonstrato that the QFBs are bounded by the reload bundle thermal limits with the exception of Critical Power Ratio (CPR). Thorofore, the thermal limits of the GE8X8NB bundle will be applied to the QFDs for all limits except the CPR. The Minimum CPR valuon for the QFBs are found in Figures 14 and 15 and in Tables 2 and 3. Specific values for all thermal limita are given for the Gell QFB (LUA307).
