Th:s3 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 thermal limits 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 a maximum feedwater temperature reduction of 55 F Feedwater Tempt.rature Reduction (FWiR), to a maximum feedwater temperature reduction of 55 F This r port contains all thermallimn parameters related to the implementation of the ARTS Improvement Pr:grrm and Maximum Extended Load Line Limit Analyses (ARTS /MELLLA) for Peach Bottom Unit 3

' l Cycl 312.

MAPLHGR LIMIT'S i

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 uran; which comprise a given fuel type as a function of average planar exposure. The MAPLHGR figuresi ar] used when hand calculations are required as specified in Reference (6). All MAPLHGR values for ccch fuel type as a function of axiallocation and average planar exposure shall be less than or equal th3 applicable MAPLHGR limits for the respective fuel and lattice types to be in compliance with Tcchnical Specification 3.2.1. These MAPLHGR limits are specified in References (3), (4), (5), (16) an the process computer databank. The SPC LFAs will be monitored to the modified GE98-P8DWB320-10GZ (Peach Bottom 2 Reload 8 bundle) MAPLHGR limits per References (10) and (16). The ARTS-4 bas:d MAPLHGR power-dependent multipliers (MAPFAC(P)) are provided in Figures 5 and 6. Figure is vzlid for seven or more (of nine) Turbine Bypass Valves (TBVs) In-Service. Figure 6 is valid for three cr more (of nine) TBVs Out-of-Service (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 flow-d: pendent MAPLHGR multipliers were obtained from Reference (15). The power-dependent MAPLHGR multipliers were obtained from Reference (18).

MCPR LIMITS Tha Operating Limit MCPR (OLMCPR) for use in Technical Specification 3.2.2 for each fuel type is give l

in Table 1. These values are determined by the cycle-specific fuel reload analyses in Reference (2). Th OLMCPR is increased by 0.01 when operating in SLO (due to the safety limit MCPR increase).

Control rod scram time verification is required as per Technical Specification 3.1.4, " Control Rod Scram 1 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 Eccordance with site procedures.

S:parate MCPR values are presented herein for the following domains:

Core Flow s 100% of Rated, No FWHOOS/FWTR, TBVs in-Service Core Flow > 100% of Rated, up to 110% of Rated, With or Without FWHOOS/FWTH, TBVs in-Service Core Flow s 100% of Rated, FWHOOS/FWTR, TBVs in-Service Turbine Bypass Valves Out-of-Service (TBVOOS), 3 or more out-of-service, With All Other Domains The OLMCPR values are documented in Reference (2) for the GE11 and GE13 fuel designs and

-l R:f:rences (10) and (20) for the SPC LFAs.

The ARTS-based power-dependent MCPR limits,.0LMCPR(P), for use in Technical Specification 2.2 m provided in Figures 9 and 10. Figure 9 is valid for seven or more TBVs in-Service. Figure 10 is valid f:r three or more TBVOOS. The flow-dependent MCPR limits, OLMCPR(F), are provided in Figure 11.

The flow-dependent OLMCPR curves were obtained from Reference (15). The power-dependent

i-OVERAIi GOVERNING MCPR AND MAPLHGR UnalTS ARTS provides for power- and flow-dependent thermalIimit adjustments and multipliers which allow for a m:ra reliable administration of the MCPR and MAPLHGR thermallimits. At any given power / flow (P/F) stat), all four limits are to be determined: MAPFAC(P), MAPFAC(F), OLMCPR(P), and OLMCPR(F) from

' Figurcs 5 through 11, inclusive [per References (7), (15) and (18)). The most limiting MCPR and the -

most limiting MAPLHGR [ maximum of OLMCPR(P) and OLMCPR(F) and minimum of MAPLHGR(P) and 4 MAPLHGR(F)) for a given (P,F) condition will be the governing limits. The OLMCPR for each fuel typ d t:rmined 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 coothig systnm analyses. Supporting documentation for the ARTS-based limits is provided in Reference (6).

' Th3 RBM' power-biased Analytical Limits, Allowable Values and MCPR Limits for. Use in Technical Sp:cification 3.3.2.1 are provided in Table 2 per References (7) and (8) with supporting documentation in {

Ref:rances (2),'(11) and (12). i I

' LINEAR HEAT GENERATION RATES Tha btginning of life (maximum) design LHGR limits for each fuel type for use in Technical Specification i

3.2.3 are provided in Table 3. Conservative LHGR values as a function of fuel evow.m are provided in ths process computer data bank and References (3) and (19). The bases for these LH7R values are

, d cumented in References (6) and (10).

STEAM BYPASS SYSTEM OPERABILITY

. - Tho operability requirements for the steam bypass system are governed by Technical Specification 3.7.6 j

. and are further discussed in Reference (9). If the requirements cannot be met, the' appropriate l powar/ flow-dependent limits for TBVOOS must be used (Table 1 with Figures 6 and 10). The minimum l number of bypass valves to maintain system operability is seven as per References (2) and (9) and Table -

4. Table 4 also includes other Turbine Bypass Valve parameters.

l (1) These Trip Level Settings (with RBM filter) are based on the rated RWE MCPR limit which is less than or equal to the minimum cycle OLMCPR (see COLR references 1,7 and 11).

l (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 reference 7 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 reference 7 and TS Table 3.3.2.1-1).

(4) This time delay option is currently not in use at Peach Bottom Unit 3 (see COLR reference 7).
