SUMMARY

' ~

This report provides the follcwing cycle-specific para .eter limits f:r Limerick Genera:Ing 2:stien Unit 2 Cycle 6:

  • Maximum Average Pla- cr Linear Heat Generation Rate (MAPLHGR)

Minimum Critical Fower Ratio (MCPR)

ARTS MCPR thermal limit adjustments and multipliers ARTS MAPLHGR thermal limit multipliers Rod. Block Monitor 'RBM) setpoints

  • MAPLHGR single '.ccp operation (SLO) reduction fa::or
  • Linear Heat Generation Rate (LHGR)
  • Turbine Bypass "alve parameters
  • Recirculation Fu p Motor Generator (MG) Set Scoop Tube Stops
  • Reactor Coolan System Recirculation Flow Upscale Trips These values have been determined using NRC-approved methodology,

' Reference 19, and are established such that all applicable limits f the plant safety analys:.s are met.

This report is submitted in accordance with Technical 5pecification

f. .l.9 of Reference .

Preparat:.cn of this report .;as performed in accordance with PECC ::uclear, Fuel & Services Division Procedure T.4-200.

The data presented in his report is valid for all points and domains on the operating map, including:

  • Maximum Extended ' cad Line Limit IMELLL) do'c. :o 81% of rated core ficw during full power operaticn
  • Increased Ccre F'. w (:CF) up to 110% of rated ::re flow
  • Feedwater Temperature Reduction (FWTR) up :: :5 F during cycle extens.:n :peration
  • Feedwater Heater Out of Service ( F"WHOOS ) ;p :o 60 F feedwater temperature reduction at any time furing the cycle prior Oc cycle extension.

MAPLHGR LIMITS The limiting MAFLH3R value for the most limi .ng lattice excluding natural uran:.um) of each fuel type as a function of average planar exposure is given in Figures 1 through E. References 3, 4, 5 and 6. These figures are used when hand calculations are required as specified in Technical Specification 2.2.1. ,

j For single loop Operation, a reduction f actor s used which is shown in Table 3 (Reference 13). {

each fuel type is given in Table 1, Reference 2. This table is l valid for all Cycle 6 fuel types and operating nomains. l Inf0r.ation regarding the treatment of these MCPR limits for SLO is also provided.

Sounding MCPR values are also provided for incperable Rec:.rculation Pump Trip (RPTOCS) or inoperable Steam Eypass System (TEV225). These two options represent the Equipment Out of Service (ECCS; condition.

ote that in Table 1 the term " EOR" refers to the cycle exposure at which operation at " rated conditions" is no longer poss:.hle (i.e., the cycle exposure at which cycle extension beg ns). The cycle exposure which represents " EOR" is given in the lates: verified and approved Cycle Management Report. This value can :hange during the cycle due to changes in operating strategy.

ARTS THERMAL LIMIT ADMINISTRATION ARTS provides for power- and flow-dependent thermal limit adjustments and multipliers which allow for a more reliable adm n:.stration of the MCPR and MAPLHGR thermal limits. The flow-dependent adjustment MCPR(F) :s sufficiently generic : apply to all fuel types and operating domains, Reference 18. However. there <

are : 0 sets of flow-dependen: MAPFAC(F) multipliers f:r dual-loop and s ngle-loop operation, References '8 and 11, respectively. In addi::.:n , there are also two sets of power-dependent :GPLHGR multi;;.ers for with- and withcut-EOOS conditions, References 9 and 7, respectively. Finally, there are two sets of power-dependent MCFR adjustments and multipliers for with- and  :::hout-EOOS cond:.n:ns, Reference 11.

!hese adjustments and multipliers are shown in Figures 9 thr:uph ' 5. Thermal limit monitoring must be performed c h the

~

more _ :::ing MCPR and MAPLHGR limits resulting f rom the p:wer- and ficw-nased calculation.

ROD BLOCK MONITOR SETPOINTS The ARTS RBM provides for power-dependent RBM trips. The trip setp: nts/ allowable values and applicable RBM signal filter time constan: data are shown in Table 2. These 'calues are f:r use with Tecnn . al Specification 3.3.6. The use of the setpoints specified in Table 2 is documented in References 2, 9, 10, and 14.

LINEAR HEAT GENERATION RATES l The maximum LHGR value for each fuel type for use .n Te::.a.ical Spe:. fica: ion 3.2.4 is given in Table 4. The LHGR is an exposure dependen: value. Due to the .treprietary nature of these calues only ne maximum LHGR for each fuel type is listed in Table ,. The LHGR data is listed in References 2 & 4 (GE proprietary

PECO NucicCr, Fual & ScrvicOO Divi 0 ion PECO-COLR-L2R5 L2RS Coro Oper ting Limito Report Page 5, Rev. O STEAM BYPASS SYSTEM OPERABILITY The operability requirements for the steam bypass system for use in Technical Specifications 3.7.8 and 4.7.8.C are found :.n Table 5, Reference 12. If these requirements cannot be met , the MCPR, MCPR(P) and MAPFAC(P) limits for inoperable Steam Bypass System, known as Turbine Bypass Valve Cut Of Service (TBVOOS), must be used.

RECIRCULATION PUMP TRIP OPERABILITY If the recirculation pump trip is inoperable, then the MCFR, MCPR(P) and yAFFAC (P) limits for Recirculation Pump Trip Out Of Service (RPTOCS), must be used.

RECIRCULATION PUMP MOTOR-GENERATOR (MG) SET SCOOP TUBE STOPS The electrical and mechanical s cps are set to limit the reactor core :colant flow rate during an event in which the recirculation ficw rate increases to its maximum value.

Specification Eurveillance Requirement number 4.4.1.1.2 Technical requires that each pump MG set scoop tube mechanical and electrical step shall be demonstrated OPERABLE, with cverspeed setpoints less than or equal to specified values, at least once per 24 months. The settings of these stops may be changed during the cycle in accordance with changes in. operational strategy. These values are cycle-specific and can be"found in Table 6 of this COLR. 1 I

CONTROL ROD BLOCK INSTRUMENTATION REACTOR COOLANT SYSTEM RECIRCULATION FLOW UPSCALE TRIP Technical Specification Limiting :endition for Operat.cn number 3.3.6 requires control rod bicck instrumentation channels shall be OPE 1? with their trip setp:;nts consistent with the values shown in the Trip Setpoint column f Technical Specificat:.cn Table 3.3.6-2. The Reactor Coolant System Recirculation Flcw Upscale Trip s a cycle-specific value and as such is found in Table 7 of this COLR. Table 7 lists the Nominal Trip Setpoint and Analytical Value. These setpoints are set high enough to allow full utilicati n of the enhanced ICF dcmain up to 110% of rated core flow. Reference setpoint values used.

These bundles previously res; fed in Limerick Unit 1 Cycles 5, 6 and 7 They have spent one year in the Limerick fuel pcci and have been inspected prior to being ;nserted into this cycle. These bundles are part :f a joint 3E-FE::N Lead Test Assembly LTA) pro";rram. This LTA

PECO Nuclocr, FuOl & S0rvic00 Divicion PECO-COLR-L2R5 L2R5 C:re Operating Limito Report PCge 6, Rev. O program was implemented in order to obtain fuel bundle data at high exp.osure,s (beyond the :urrent Gell licensed limit of 70 GWd/MT Peak Pellet Exposure, Reference 17).. A PECON 10CFR50.59 Review has been performed for the use of these bundles in a fourth cycle. No Unreviewed Safety 'uestions were identified. New MAPLHGR and DESLIM limits, respectively used for calculating MAPRAT and MFLPD, have been determined by the fuel vendor and are shown in Figure 6 and Table'4. See References 2, 3, 15 and 16 for more information on these bundles. i SAFETY LIMIT MINIMUM CRITICAL POWER RATIO (SLMCPR)

The Safety Limi: Minimum Critical Power Ration (SLMCPR) for Limerick 2 Cycle 6 is 1.12 for Dual Loop Operation and 1.14 for Single Loop Operation. These values are documented in Reference 2.
