SUMMARY
This report provides the cycle-specific parameter limits for:
Maximum Average Planar Linear Heat Generation Rate (MAPLHGR);
j Minimum Critical Power Ratio (MCPR);
ARTS MCPR thermal limit adjustments and multipliers; ARTS MAPLHGR thermal limit multipliers; Rod Block Monitor (RBM) data; MAPLHGR single loop operation (SLO) reduction factor; Linear Heat Generation Rate (LHGR); Turbine Bypass Valve parameters; Recirculation Pump Motor Generator (MG) Set Scoop Tube Stops; and Reactor Coolant System Recirculation Flow Upscale Trips for Limerick Generating Station Unit 1,
Cycle 7.
These 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 is submitted in accordance with Technical Specification 6.9.1.9 of Reference 1.
Preparation of this report was performed in accordance with PECO Energy Company, Fuel &
Services Division Procedure FM-300.
The cycle-specific parameter limits presented in this report are applicable for operation at a rerated power level of 3458 MWt.
This is the first cycle of power rerate operation at Limerick-1.
The data presented in this report is valid for all points and domains on the operating map including Maximum Extended Load Line Limit (MELLL) down to 81% of rated core flow during full power operation, Increased Core Flow (ICF) up to 110% of rated core flow, Feedwater Temperature Reduction (FWTR) up to 105'F during cycle extension operation and Feedwater Heater Out of Service (FWHOOS) up to 60*F feedwater temperature reduction at any time during the i
cycle prior to cycle extension operation.
MAPLHGR LIMITS MAPLHGR curves for each Cycle 7 fuel type as a function of average planar exposure are given in Figures 1-5.
No reduction in MAPLHGR limits is required under ARTS during single loop operation (Table 3).
MCPR LIMITS The MCPR value for use in Technical Specification 3.2.3 is given in Table 1.
This table is valid for all Cycle 7 fuel types and operating domains.
Information~ regarding the validity of these MCPR limits for SLO is also provided.
Bounding MCPR values are provided for inoperable Recirculation Pump Trip (RPTOOS) and for inoperable Steam Bypass System (TBVOOS).
These two options represent the Equipment Out of Service (EOOS) condition.
Note in this table the term " EOR" refers to the cycle exposure at which operation at " rated conditions" is no longer possible (i.e.,
the cycle exposure at which cycle extension begins).
The cycle exposure which represents
" EOR" is given in the latest revision of the Cycle Management Report.
This value can change
P2CO Entrgy Fu3l & SOrvic30 Divicien PCCO-COLR-LlR6 LlR6 Core Operating Limits Report Page 4, Rev. O during the cycle due to changes in operating strategy.
1 ARTS TEERMAL LIMIT ADMINISTRATION i
ARTS provides for power-and flow-dependent thermal limit l
adjustments and multipliers which allow for a more reliable j
administration of the MCPR and MAPLHGR thermal limits.
The flow-i dependent multiplier MAPFAC(F) and flow-dependent adjustment
'i MCPR(F) are sufficiently generic to apply to all fuel types and operating domains.
The appropriate value of these flow-dependent parameters is chosen based on the maximum allowable core flow setting (for the mechanical stop) presented in Table 5.
There are.
two sets of power-dependent MAPLHGR multipliers for with-and without-EOOS conditions.
- Also, there are two sets of power-t dependent MCPR adjustments and multipliers for with-and without-EOOS conditions.
These adjustments and multipliers are shown in Figures 6 i
1 through 11.
Thermal. limits monitoring must be performed with the more limiting MCPR and MAPLHGR limit resulting from the power-/ flow-biased calculation.
ROD BLOCK MONITOR SETPOINTS The ARTS RBM provides for power-dependent RBM trips to replace the previous flow-dependent trips.
The trip setpoints/ allowable values and applicable RBM signal filter time constant data are shown in Table 2.
LINEAR REAT GENERATION RATES The LHGR value for each fuel type for use in Technical Specification 3.2.4 is given in Table 7.
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 in Table 4.
If these requirements cannot be met, then the MCPR, MCPR(P) and MAPFAC(P) limits for TBVOOS must be used.
l RECIRCULATION PUMP TRIP OPERABILITY If the recirculation pump trip is inoperable, then the MCPR, MCPR(P) and MAPFAC(P) limits for RPTOOS must be used.
PZCD En Ngy Fuol & SOrvicto Divicicn PECO-COLR-L1R6 L1R6 Core Operating Limits Report Page 5, Rev. O RECIRCULATION PUMP MOTOR-GENERATOR (MG) SET SCOOP TUBE STOPS The electrical and mechanical stops are set to limit the reactor core coolant flow rate during an event in which the recirculation flow rate increases to its maximum value.
Technical Specification Surveillance Requirement number 4.4.1.1.2 requires that each pump MG set scoop tube mechanical and electrical stop shall be demonstrated OPERABLE, with overspeed 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 i
l accordance with changes in operational strategy.
The values of-these settings can be found in Table 5 of this COLR.
CONTROL ROD BLOCK INSTRUMENTATION REACTOR COOLANT SYSTEM RECIRCULATION FLOW UPSCALE TRIP Technical Specification Limiting Condition for Operation number 3.3.6 requires control rod block instrumentation channels shall be OPERABLE with their trip setpoints consistent with the values shown in the Trip Setpoint column of Technical Specification Table 2.3.6-2.
The Reactor Coolant System Recirculation Flow Upscale Trip is a cycle-specific value and as such is found in Table 6 of this COLR.
Table 6 lists the Nominal Trip Setpoint and Allowable Value.
These setpoints are set high enough to allow full utilization of the enhanced ICF domain up to 110% of rated core flow.
