SUMMARY
This report provides the following cycle-specific parameter limits for Peach Bottom Atomic Power Station Unit 2 Cycle 13 (Reload 12): )
- e Maximum Average Planar Linear Heat Generation Rate (MAPLHGR)
ARTS MAPLHGR thermallimit multipliers Single Loop Operation (SLO) MAPLHGR multipliers l Minimum Critical Power Ratio (MCPR)
ARTS MCPR thermal limit adjustments and multipliers Single Loop Operation (SLO) MCPR adjustment Rod Block Monitor (RBM) Analytical Limits, Allowable Values and MCPR Limits I Linear Heat Generation Rate (LHGR) l
. Turbine Bypass Valve Parameters Thrse 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 provides the means for calculating the Operating Limit MCPR and MAPLHGR thermallimits for th3 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
. Increased Core Flow (ICF), up to 110% of rated core flow End-of-Cycle Power Coastdown to a minimum power level of 40%
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 90* F temperature reduction The Allowable Values, documented in Reference 17, for feedwater temperature as a function of thermal p:wer for both FWHOOS and FWTR are specified in the appropriate Peach Bottom procedures.
N:te that the term " 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.
l Preparation of this report was performed in accordance with PECO Energy Fuel and Services Division Pracedure FM 300, " Reload Core Licensing". This report is submitted in accordance with Technical
!' Sp cification 5.6.5 of Reference (1) and contains all thermallimit parameters related to the implementation of tha ARTS Improvement Program and Maximum Extended Load Line Limit Analyses (ARTS /MELLLA) for Peach Bottom Unit 2 Cycle 13.
. , PECO Energy Fuel and Services DMsion PECO-COLR-P2013 l P2C13 Core Operating umits Report Page 4, Rev.1 MAPLHGR LIMITS The bounding MAPLHGR limits (kW/ft) for each fuel type are provided in Figures 1 through 5. 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 functior.
of axiallocation 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 limits are specified in References (2), (3), (15) and (16) and the process computer databank. 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 Recirculation Pump Trip (RPT) in-Service with a maximum temperature reduction of 90' F for FWTR operation. Figure 7 is valid for three or more (of nine) TBVs Out-of-Service (OOS) or RPTOOS with a maximum FWTR of 90' 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 SLO MAPLHGR multiplier (0.87) is applied through MAPFAC(F) as shown in Figure 9. MAPFAC(F)is clamped at 0.87 starting at 54.55% of rated core flow to ensure peak clad temperatures are maintained within the limits of the cycle-specific LOCA analysis for single recirculation loop operation. The power- and flow-dependent MAPLHGR multipliers were obtained from References (5), (11),
(17) and (18).
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).
Control rod scram time verification is required as 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).
Separate MCPR values are presented herein (Table 1) for the following domains:
TBVs In Service (seven or more in-service) and RPT In-Service, maximum FWTa of 90 F
. TBVs Out-of-Service (three or more out-of-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 OLMCPR values are documented in References (2) 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 Figure 10. Figure 10 is valid for all operating conditions. The flow-dependent MCPR limits, OLMCPR(F), are provided in Figure 11. Figure 11 is valid for all operating conditions. The OLMCPR(P) values below the turbine scram bypass power are documented in Reference (17). OLMCPR(P, F) curves were obtained from References (5), (11), (17) and (18).
OVERALL GOVERNING MCPR AND MAPLHGR LIMITS ARTS provides for power- and flow-dependent thermal limit adjustments and multipliers which allow for a more reliable administration of the MCPR and MAPLHGR thermallimits. At any given power / flow (P/F) state.
l
(
.. . PECO Energy Fuel and Servlees DMelon PECO-COLR-P2C13 l P2C13CoreOperaungumnsReport Page 5, Rev.1 all four limits are to be determined: MAPFAC(P), MAPFAC(F), OLMCPR(P), and OLMCPR(F) from Figures 6 throogh 11, inclusive. The most limiting MCPR and the most limiting MAPLHGR [ maximum of OLMCPR(P) 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-m@chanical and emergency core cooling system analyses. Supporting documentation for the ARTS-based limits is provided in References (5), (10), (11), (14), (17), and (18).
ROD BLOCK MONITOR SETPOINTS l The RBM power-biased Analytical Limits, Allowable Values and MCPR Limits for use in Technical '
Specification 3.3.2.1 are provided in Table 2 per Reference (5) with supporting documentation in References (2), (11), (12) and (13). '
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 3. The LHGR values as a function of fuel exposure are provided in Reference (3). The bases for the LHGR values are documented in Reference (4).
STEAM BYPASS SYSTEM OPERABILITY The operability requirements for the steam bypass system are govemed by Technical Specification 3.7.6. If the requirements cannot be met, the appropriate power dependent limits for Turbine Bypass Valves Out-of-Service (TBVOOS) must be used (Table 1 with Figure 7). - The minimum number of bypass valves to maintain system operability is seven as per References (6; and (9) and Table 4. Table 4 also includes other Turbine Bypass Valve parameters.
EOC RECIRCULATION PUMP THIP ( EOC-RPT) OPERABILITY If the EOC-RPT is inoperable, then the OLMCPR (Table 1) and MAPFAC(P) limits (Figure 7) for EOC Recirculation Pump Trip Out-of-Service (RPTOOS), must be used.
The measured EOC-RPT response time as defined in Section 1.1 of the Technical Specifications shall be :
s 0.145 seconds for TGV Fast Closure Trip (i.e. Generator Load Rejection) s 0.155 seconds for TSV Fast Closure Trip ( i.e. Turbine Trip )
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 (19) provides the basis for the RPT response time.
I CONCURRENTTBVOOS AND RPTOOS Cycle 13 is not licensed for TBVOOS and RPTOOS to occur concurrently. Therefore, concurrent TBVOOS and RPTOOS is an unanalyzed condition.

(1) These Trip Level Settings (with RBM filter) are based on a cycle-specific rated RWE MCPR limit of 1.30 and are consistent with an RBM filter time constant between 0.1 and 0.55 seconds. (2) This is the MCPR limit (given THERMAL POWER 2 28.3% and < 90% RTP) below which the RBM is required to be OPERABLE (see COLR references 2 and 5 and TS Table 3.3.2.1-1). (3) This is the MCPR limit (given THERMAL POWER 2 90% RTP) below which the RBM is required to be OPERABLE (see COLR references 2 and 5 and TS Table 3.3.2.1-1). (4) This time delay option is currently not in use at Peach Bottom Unit 2 (see COLR reference 5).
