PECO Entrgy Fuol and Scrvicco Divisicn PECO-COLR-L1R5 L115 Ccro Optrating Limits Report P g3 3, Rev. 4 INTRODUCTION AND
SUMMARY
This report provides the cycle-specific parameter limits for:
Maximum Average Planar Linear Heat Generation Rate (MAPLHGR);
Minimum Critical Power Ratio (MCPR); ARTS MCPR. thermal limit adjustments and multipliers; ARTS MAPLHGR thermal limit multipliers; Rod Block Monitor (RBM) setpoints; 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 6.
These values have been determined using NRC-approved methodology and are established such that all applicable j
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 Fuel and Services Division Procedure FM-300.
This report contains all thermal limit parameters related to the implementation of the Mav4== Extended Load Line Limit and ARTS Improvement Program analyses (ARTS /MELLLA) for Limerick-1 Cycle 6.
This is the first application of ARTS /MELLLA at Limerick Generating Station.
Revision 4 of the Limerick-1 Cycle 6 COLR contains revised Recirculation Pump Motor-Generator (MG) Set Scoop Tube Stops and I
the corresponding MCPR (F) and MAPFAC(F)
ARTS thermal limits adjustments and multipliers. The MG Set Scoop Tube Stops are being reset to allow access to the relatively higher core flow region of the licensed operating domain (up to 110% of rated) in order to improve reactor maneuvering capability. More restrictive values of MCPR (F) and MAPFAC(F) must therefore be used for thermal limits administration to ensure compliance with fuel licensing limits in the event of a recirculation flow increase event.
e
PECO 6:rgy PuOl and'S rvicOc Divicicn PECO-COLR-L1R5 L115 Caro Optrating Limits Rep 3rt Pago 4, Rev. 4 MAPLEGR LIMITS The 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 6.
No reduction in MAPLHGR limits is required under ARTS during single loop operation (Table 2).
MCPR LIFLTS The MCPR value for use in Technical Specification 3.2.3 is given in Figures 7 through 10.
These tables are valid for'all Cycle 6 fuel types.
Information regarding the validity of these MCPR limits in various operating domains and for SLO is also' provided.
The MCPR values shown in these figures are the bounding values for all points on the power flow map including Maximum Extended Load Line Limit (MELLL) down to 75% of rated core flow during full power operation, Increased Core Flow (ICF) up to 110% of rated core flow, Rated Core Flow (RCF, the area between the MELLL and ICF operating domains), Feedwater Temperature Reduction (FWTR) up to 105'F at end of cycle, Feedwater Heater Out of Service (FWHOOS) up to 60*F feedwater temperature reduction during the cycle, and Power Coastdown operation.
Bounding MCPR values are also provided for inoperable Recirculation Pump Trip (RPTOOS) or inoperable Steam Bypass System (TBVOOS). These two options represent the Equipment Out Of Service (EOOS) conditions.
Note in these figures the term "EOC" 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) which was assumed during the cycle specific reload licensing (Reference 2).
ART!$ TEIRMAL LIMIT ADMINISTRATION 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.
The flow-dependent multiplier MAPFAC(F) and flow-dependent adjustment MCPR (F) are sufficiently generic to apply to all fuel types and operating domains.
There are two sets of power-dependent MAPLHGR multipliers for with-and without-EOOS conditions.
There are two sets of power-dependent MCPR adjustments and multipliers for with-and without-EOOS conditions.
These adjustments and multipliers are shown in Figures 11
PECO Energy Fu:1 and ServicOc Divicien PECO-COLR-L1R5 L1R5 Core Operating Limits Report Page da, Rev. 3 through 16.
I ROD BLOCK MONITOR SETPOINTS The ARTS RBM provides for power-dependent RBM trips to replace the previous flow-dependent trips.
The trip setpoints and applicable RBM signal filter time constant data are shown in Table 1.
LINEAR EEAT GENERATION RATES The LHGR value for each fuel type for use in Technical i
Specification 3.2.4 is given in Table 3.
STEAM BYPASS sisim.si OPWBAMILITY 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, the thermal limit multipliers and MCPR limits for Turbine Bypass Valve Out of Service (TBVOOS) must be used.
RECIRCULATION PUMP MOTOR-GEMT#1 TOR (MG) SET 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.
These values are cycle specific and can be found in Table 5 of this COLR.
CONTROL ROD BLOCK INSTRUMENTATION BN' TOR COOLUM' sisrrri RECIRCUTATION FLOW UPSr'au 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 3.3.6-2.
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 Trip Setpoint and Allowable Value.
