SUMMARY
This report provides the following cycle-specific parameter limits for Peach Bottom Atomic Power Station Unit 2 Cycle 12 (Reload 11)-
l I
Maximum Average Planar Linear Heat Generation Rate (MAPLHGR) l 1
ARTS MAPLHGR thermal limit multipliers e
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) Analytical Limits, Allowable Values and MCPR Limits Linear Heat Generation Rate (LHGR).
.' Turbine Bypass Valve Parameters l
These values have been determined using NRC-approved methodology and are established such that all applicable limits of the plant safety analysis are met.
ihis report provides the means for calculating the Operating Limit MCPR and MAPLHGR thermallimits 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 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 E,d-of-Rated (EOR) and End-of-Cycle l
(EOC) to 90' F temperature reduction The ' Allowable Values, documented in Reference 21, for feedwater temperature as a function of thermal pesver for both ~WHOOS and FWl'R are specified in the appropriate Peach Bnttom procedures.
Note that the term " EOR" refers to the cycle exposure at which o;:aration 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.
Preparation of this report was performed in accordance with PECO Energy Fue! and Services Division Procedure FM-300, " Reload 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 Analysis (ARTS /MELLLA) for
! Peach Bottem Unit 2 Cycle 12.
PECO Energy Fuel and Services Division PECO-COLR-P2C12 l P2C12 Core Operating Limits Report Page 4, Rev.6 MADLHGR LIMITS The bounding MAPLHGR limits (kW/ft) for each fuel type are provided in Figures 1 through 4. The bounding MAPLHGR lirnits 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 locatior: 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 Referencas (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 7. 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 reri ction of 90' F for FWTR operation. Figure 7 is valid for three or more (of nine) TBVs Out-of-Service (OOS) and FWTR operation of 90* F. The flow-dependent multiphers (MAFFAC(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 l from References (5), (12), (16), (19), (21), (23), and t24).
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 determi,ied 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.imit MCPRs are documented in Section 2.1.1.2 of Reference (1).
Conjol 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 positiort 36 throughout the cycle, is detennined hased 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 Opt:on B) and 1.0 (Tau Option A).
Separate MCPR values are presented herein (Table 1) for the following domains:
- Core Flow s 100% of Rated, No FWHOOS/FWTR, TB\\'s In-Service (seven or more in-service)
Core F',w > 100% of Rated, with or without FWHOOS/FWTR, TBVs in-Service Core Flow s 100% of Rated, with FWHOOS or FWTR, TBVs in-Service TBVs Out-of-Service (three or more out-of-service) with all other domains l The OLMCPR values are documented in References (2), (19), (21), 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 10,11, 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 ninc) TBVs In-Service and temperature reduction of 90* F for FWTR operation. Figure 12 is valid for three or more TBVOOS and temperature reduction of 90* F for FWTR operation. The flow-dependent MCPR limits, OLMCPR(F), are
.l provided in Figure 13. The OLMCPR(P) values below the turbine scram bypass power are d References (19), (21), and (24). OLMCPR(P, F) curves were obtained from References (5), (16), (17), (19),
(21), (23), and (24).
PECO Energy Fuel and Services Division PECO-COLR P2C12 l P2C12 Core Operating Umits Report Page 5, Rev. 6 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, all four limits are to be determined: MAPFAC(P), MAPFAC(F), OLMCPR(P), and OLMCPR(F) from Figures 5 through 13, 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 goveming 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 limits is provided in References (5), (6), (12), (16), (17), (19), (21), (23), (24) and (25).
ROD BLOCK MONITOR SETPOINTS
.The RBM power-biased Analytical Limits, Alloweble 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-cf-Cycle (BOC) to the End-of-Rated (EOR) - 2000 mwd /ST statepoint. Either Table'2 or Table 3 may be used from EOR - 2000 mwd /ST to End-of-Cycle (EOC).
j LINEAR HEAT GENER ATION RATES l
The beginning of life (maximum) LHGR values for each fuel type for use in Technical Specificatici. 3.2.3 are provided in Table 4. Conservative LHGR values as a function ci fuel exposure are provided in the process computer data bank. LHGR values are documented in References (4) and (13).
STEAM BYPAS3 SYSTEM OPERABILITY The operability requirements for the steam bypass system are govemed by Technical Specification 3.7.6 and are further discussed in Reference (10). If the requirements cannot be met, the appropriate power / flow-deoendent 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.
