SUMMARY

This report provides the following cycle-specific parameter limits for Peach Bottom Atomic Power Station Unit 3 Cycle 11 (Reload 10): Maximum Average Planar Linear Heat Generation Rate (MAPLHGR) ARTS MAPLHGR thermallimit multipliers J Single Loop Operation (SLO) MAPLHGR multipliers

  • Minimum Critical Power Ratio (MCPR)
  • ARTS MCPR thermallimit adjustments and multipliers Single Loop Operation (SLO) MCPR adjustment Rod Block Monitor (RBM) Setpoints
  • Linear Heat Generation Rate (LHGR)

Thrae values have been determined using NRC-approved methodology and are established such that all applicable limits of the plant safety analysis are met. a This r; port provides the means for calculating the Operating Limit MCPR and MAPLHGR thermallimits for th] following conditions: all points in the operating region of the power / flow (105% rerated power,3458 MWt) mapincluding Maximum Extended Load Line Limit (MELLL) down to 81% of rated core flow during full power operation Increased Core Flow (ICF), up to 110% of rated core flow End-of-Cycle Power Coastdown (minimum power level of 40%) and intermediate points Feedwater Temperature Reduction (FWTR), to a temperature reduction of 55 F between EOR a and EOC Feedwater Heaters Out of Service (FWHOOS), to a 55 F reduction at any time during tne cycle. This report contains all thermallimit parameters related to the implementation of the ARTS Improvement l Program and Maximum Extended Load Line Limit Analyses (ARTS /MELLLA) for Peach Bottom Unit 3 Cycb 11. I NOTE: Until the Peach Bottom Unit 3 Cycle 11 cycle-specific ARTS curves are developed and L validated, the generic ARTS curves, as reported in Reference (8), will be used. This report is submitted in accordance with Technical Specification 6.9.1.e of Reference (1). Preparation .of this report was performed in accordance with PECO Energy Fuel.snd Services Division Procedure - FM-300, " Reload Core Licensing". I

T J. PE00 Energy Fuel and Services Division . PECO COLR-P3C11 P3C1f Coreoperating Limits Report Page 4, Rev. 0 - @1APLHGR LIMITS Th3 standard limiting MAPLHGR value for the most limiting lattice (excluding natural uranium) of each fuel type es a function of average planar exposure is provided in Figures 1 through 5. These figures are used wh:n hand calculations are required as specified in Technical Specification 3.5.1. These values were ~ btained from References (3), (4), (5), (6), (13) and (14). The Siemens Power Corporation (SPC) Lead o Fuel Assemblies (LFAs) will be monitored to the modified GE98-P8DWB320-10GZ (Peach Bottom 2 Reload 8 bundle) MAPLHGR limits per References (6) and (13). No reduction in the standard MAPLHGR limits -is required under ARTS during single loop opration (SLO MAPLHGR multiplier = 1.0). The ARTS-based MAPLHGR power-dependent multipliers (MAPFAC(P)) are provided in Figures 6 and 7. Figure 6 is valid for seven or more (of nine) Turbine Bypass Valves (TBVs) In-Service and Two Loop Recirculation Flow while Figure 7 is valid for three or more (of nine) TBVs Out-of-Service (OOS) or Single Loop Recirculation - Flow. 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. MCPR LIMITS Tha' Operating Limit'MCPR (OLMCPR) for use in Technical Specification 3.5.K for each fuel type is given in Tcble 1. These values are determined by the cycle-specific fuel reload analyses in Reference (2). The OLMCPR is !ncreased by 0.01 when operating in SLO (due to the safety limit increase). NOTE:; At times when the surveillance requirement of specification 4.5.K.2 is not performed, the J6 OLMCPR value corresponding to Tau =1, Opt. A in Table 1, must be used. t .Srparate MCPR values are presented herein for the following domains: 1 l

  • Core Flow Less Than or Equa! to 100% of Rated y

Core Flow Greater Than 100% of Rated, up to 110% of Rated

  • Core Flow Less Than or Equal to 100% of Rated With FWHOOS/FWTR i

Turbine Bypass Valves Out-of-Service (TBVOOS),3 or more out-of-service l Tha OLMCPR values are documented in Reference (2) for the GE9B and GE11 fuel designs and References (13) and (14) for the SPC LFAs. ! ' Tha ARTS-based power-dependent MCPR limits, OLMCPR(P), for use in Technical Specification 3.5.K are i provided in Figures 10 and 11.. Figure 10 is valid for seven or more TBVs In-Service while Figure 11 is l valid for three or more TBVOOS. The flow-dependent MCPR limits, OLMCPR(F), are provided in Figure 12. L The OLMCPR(P) values below the turbine scram bypass power are documented in Reference (9). The L values are conservatively based on a 10 inch increase (actual 6 inch) in the analytical limit for the high (L8) L.wat::r level feedwater and main turbine trip setpoint. ikgNota that in the aforementioned OLMCPR table the term " EOR" refers to the cycle ex peration at " rated conditions" is no longer possible (i.e., the cycle exposure at which cycle extension begins) based on the actual EOR point as documented in the current revision of the Cycle Management i - R:: port. i l 1

g e PECO Energy fuel and Services Division PECO-COLR P3011 P3C1f Core Operating 1.lmits Report Page 5, Rev. 0 @VERALL GOVERNING MCPR AND MAPLHCR LIMITS v ARTS provides for power-and flow-dependent the mal 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, all four limits are to be determined: MAPFAC(P), MAPFAC(F), OLMCPR(P), and OLMCPR(F) from Figures 6 through 12, inclusive [per Reference (8)]. Tha inost limiting MCPR and the most limiting MAPLHGR [ maximum of OLMCPR(P) and OLMCPR(F) & minimum of MAPLHGR(P) and MAPLHGR(F)] for a given (P,F) condition will be the governing limits. ine 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 limits is provided in References (8), (9) and (12). ROD BLOCK MONITOR SETPOINTS The RBM power-blased setpoints for use in Technical Specification 3.2.C is given in Table 2 per R:ferences (8) and (10) with supporting documentation in Reference (2). LINEAR HEAT GENERATION RATES Th3 LHGR value for use in Technical Specificmion 3.5.J for each fuel type is given in Table 3. These gilues are documented in References (7) and (13). ] STEAM BYPASS SYSTEM OPERABILITY Tha operability requirements for the steam bypass system are governed by site administrative controls as discussed in Reference (11). If the requirements cannot be met, the appropriate power / flow # ependent -d limits for TBVOOS must be used (Figures 7 and 11). The minimum number of bypass valves to maintain systam operability is seven as per References (2) and (11). TECHNICAL SPECIFICATIONS During the operation of Peach Bottom Unit 3 Cycle 11 (approximately January 1996), a change will be made from the current Technical Specifications (CTS), Reference (1), to improved Technical Specifications (ITS), Reference (15). The reload licensing for this cycle, Reference (2), was performed based on ITS. It is documented in Reference (16) that the licensing is bounding for the use of CTS until ITS is implemented. When ITS is implemented this COLR will be revised. All references to CTS will be replaced with the appropriate ITS references. This will be considered an editorial change since the licensing for PBAPS Unit 3 Cycle 11 was based on ITS.
