SUMMARY

~

This report provides the cycle-specific parameter limits for: Maximum Average Planar Linear Heat Generation Rate (MAPLHGR); Minimum Cruical Power Ratio (MCPR); ARTS MCPR thermallimit adjustments and multipliers; ARTS MAPLHGR thermal limit multipliers; Linear Heat Generation Rate (LHGR); and Rod Block Monitor (RBM) Setpoints; and a Single Loop Operation (SLO) MCPR

! adjustment for Peach Bottom Atomic Power Station Unit 2 Cycle 11 (Reload 10). These values have i

been determined using NRC-approved methodology and are established such that all applicable limits j

of the plant safety analysis are met.

J This report provides the means for calculating the Operating Limit MCPR and MAPLHGR thermal limits for all points in the operating region of the power / flow (105% rerated power) map including Maximum Extended Load Line Limit (MELLL) down to 81% of rated core flow during full power operation, Increased Core Flow (ICF), End-of-Cycle Power Coastdown and intermediate points, as well as for Feedwater Temperature Reduction (FWTR) to a temperature reduction of 55 F at end of cycle and Feedwater Heater Out of Service (FWHOOS) to a 55 F reduction at any time during the cycle.

The thermal limits in this report support ICF up to 110% of rated flow. However, ICF operation will be
limited to 105% of rated flow until the current Technical Specifications (TS) are revised or replaced by l Improved TS.

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 and Services Division Procedure FM-105, " Reload Licensing Documentation".

This report contains all thermal limit parameters related to the implementation of the Maximum Extended Load Line Limit and ARTS Imprnvement Program analyses (ARTS /MELLLA) for Peach Bottom Unit 2 Cycle 11. This is the first appl!c.fion of ARTS /MELLLA at Peach Bottom Unit 2.

ROD BLOCK MONITOR SETPOINTS The RBM power-biased setpoints for use in Technical Specification 3.2.C is given in Table 3 per Reference (5) with supporting documentation in Reference (10) and Reference (11).

MAPLHGR LIMITS 1

l The standard limiting MAPLHGR value for the most limiting lattice (excluding natural uranium) of each fuel type as a function of average planar exposure is given in Figures 1 through 8. These figures are used when hand calculations are required as specified in Technical Specification 3.5.l.

These values were obtained from References (2),(3) and (9). The Siemens Power Corporation (SPC) and Asea Brown Boveri (ABB) Atom Lead Use Assemblies (LUAs) will be monitored to modified GE98-P8DWB320-10GZ (Reload 8 bundle) MAPLHGR limits per References (12) and (13). The MAPLHGR power and flow multipliers are given in Figures 12 and 13, respectively. No reduction in MAPLHGR Umits is required under ARTS during single loop operation (SLO MAPLHGR multiplier = 1.0).

.MCPR LIMITS The rated (100% power) Operating Limit MCPR (OLMCPR) for use in Technical Specification (TS) 3.5.K for each fueltype is given in Figures 9 through 11 and in Tables 1 and 2. These values are determined by the cycle-specific fuel reload analyses in Reference (2). Table 1 is used when the requirement of TS 4.5.K.2.a is met. When this requirement cannot be met, the OLMCPR values as a function of TAU are given in Figures 9 through 11. At times when the surveillance requirement of specification 4.5.K.2 is not performed, Table 2 is used. The OLMCPR is increased by 0.01 when operating in SLO (due to the safety limit increase). All MCPR values presented herein are for the Recirculation Pump Trip Out-of-Service (RPTOOS) condition. The OLMCPR values are documented in Reference (2) for the GE88, GE9B and GE11 fuel designs, Reference (7) for SPC LUAs and Reference (8) for ABB LUAs. The ARTS-based MCPR(P) power adjustment factor for use in Technical Specification 3.5.K is given in Figure 14 and the MCPR(F) flow dependent limit is given in Figure 15.

, The MCPR(P) values below the turbine scram bypass power are documented in Reference (6). The values are conservatively based on a 10 inch increase (actual 6 inch)in the analytical limit for the high (L8) water level feedwater and main turbine trip setpoint, j

i Note in the aforementioned figures and tables that the term "EOC" refers to the cycle exposure at which operation at " rated conditions" is no longer possible (Le., the cycle exposure at which cycle extension begins) as assumed during the cycle-specific reload licensing analyses in Reference 2.

AVERALL 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 thermal limits. At any given power / flow state (P,F), all four limits are to be determined
MAPFAC(P), MAPFAC(F), MCP,R(P), and MCPR(F) from Figures 12,13,14 and 15, respectively [per Reference (5)]. The most limitin' MCPR g

and the most limiting MAPLHGR [ maximum of MCPR(P) and MCPR(F) and minimum of MAPLHGR(P) and MAPLHGR(F)] for a given (P,F) condition will be the governing limits. The rated OLMCPRs are 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. See Reference (5) for further details.

i LINEAR HEAT GENERATION RATES The LHGR value for use in Technical Specification 3.5.J for each fuel type is given in Table 4.

These values are documented in References (4), (7) and (8).
