  • Maximum Average Planar Linear Heat Generation Rate (MAPLHGR)

+ ARTS MAPLHGR thermallimit 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 Th:se values have been determined using NRC approved methodology and are established such that all cpplicable limits of the plant safety analysis are met.

This report provides the means for calculating the Operating Limit MCPR and MAPLHGR thermal limits for th; following conditions:

  • all points in the operating reglon of the power / flow map including Maximum Extended Load Line Limit (MELLL) down to 81% of rated core flow dwing 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) or Feedwater Temperature Reduction (FWTR) to a temperature reduction of 55 'F This rcport 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.

This r: port is submitted in accordance with Technical Specification 5.6.5 of Reference (1). Preparation of this report was performed in accordance with PECO Energy Fuel and Services Division Procedure FM 300,' Reload Core Licensing".

PECO Energyfuel and Services Divlelon PECO COLR P2012 l P2C12 Core Opersting Umits Report Page 4, Rev.3 MAPLHGR LIMITS Tha bounding 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 us:d when hand calculations are required as specified in Reference (4). All MAPLHGR values for each fu:1 type as a function of axiallocation and average planar exposure shall be less than or equal to the cpplicable MAPLHGR limits for the respective fuel ar'd lattice types to be in compilance w:th Technical Specification 3.2.1. These MAPLHGR limits are specified in References (2), (3), (7) and (20) and the process computer databat. No reduction in the standard MAPLHGR limits is required under ARTS during single Inop operation . SLO MAPLHGR multipiler - 1.0). The ARTS based MAPLHGR power-

- dependent multipliers (MAPFAC(P)) are provided in Figures 5 and 6. Figure 5 is valid for seven or more (of nine) Turbine Oypass Valves (TBVs) In Service. Figure 6 is valid for three or more (of nine) TBVs Out-of S:rvice (OOS). The flow dependent multipliers (MAPFAC(F)) are provided in Figures 7 and 8 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) and (19).

MCPR LIMITS Tho 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 Scf:ty 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 Tim:s". Tau, a measure of scram time performance to notch position 36 throughout the cycle, is d:t:rmined based on the cumulative scram time test results. The calculation of Tau shall be performed in cccordance with site procedures. Linear interpolation shall be used to calculate the OLMCPR value if Teu is between 0.0 (Tau Option B) and 1.0 (Tau Option A).

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

  • Core Flow s 100% of Rated, No FWHOOS/FWTR, TBVs In Service (seven or more in service)

+ Core Flow > 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 Tha OLMCPR values are documented in References (2) and (19) 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 9 and 10. Figure 9 is valid for seven or more TBVs In Service. Figure 10 is valid for three or more.TBVOOS. The flow dependent MCPR limits OLMCPR(F),--are provided in Figure 11.

The OLMCPR(P) values below the turbine scram bypass power are documented in Reference (19).

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

Not] that in the aforementioned OLMCPR table the term " EOR" refers to the cycle exposure at which operction 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 l P2012 Core Operating Limits Report Pope 5, Rev. 3 OVERALL GOVERNING MCPR AND MAPLHOR. LIMITS ARTS provides for power and flow dependent thermallimit adjustments and multipliers which allow for a more reliable administration of the MCPR and MAPLHGR thermallimits. At any given power / flow (P/F) st:to, all four limits are to be determined: MAPFAC(P), MAPFAC(F), OLMCPR(P), and OLMCPR(F) from i Figures 5 through 11, inclusive. The moct limiting MCPR and the most limiting MAPLHGR [ maximum of l

- OLMCPR(P) and OLMCPR(F) and minimum of MAPLHGR(P) and MAPLHOR(F)) for a given (P,F) ,

condition will be the governing limits. The OLMCPR for each fuel type is determined by the cycle specific 6

fu:1 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) and (19).

ROD BLOCK. MONITOR SETROINTS The RBM power blased 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 Ref:rences (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 mwd /ST to End of Cycle (EOC).

UNEAR HEAT. GENERATION RATES Tha 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 proc:ss computer data bank. LHGR values are documented in References (4) and (13).

STEAM BYPASS SYSTEM OPER ABILITY 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 l pow uflow-dependent limits for TBVOOS must be used (Table 1 with Figures 6 and 10). The minimum number of bypass valves to maintain system operability is seven as per References (9) and (10) and Tcblo 5. Table 5 also includes other Turbine Bypass Valve parameters.
