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; Id o ur Heat Generation Rate (LHGR) ; and Turbine Bypass Valve parameters for Limerick Generating Station Unit 1, Cycle 6.
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 Fuel and Services Section Procedure FM-105.
This report contains all thermal limit parameters related to i
the implementation of the Maximum Extended Load Line Limit and ARTS i
Improvement Program analyses (ARTS /MELLLA) f or Limerick-1 Cycle 6.
This is the first application of ARTS /MELLLA at Limerick Generating Station.
MAPLHGR 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 operatior. (Table 2).
MCPR LIMITS 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 thess 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 1050F at end of cycle, Feedwater Heater Out of Service ( FWHC+0S ) up to 600F f eedwater temperature reduction during the cycle, and Power Coastdown operation.
Bounding MCPR values are also provided for inoperable 4
i
.PECO Fuel and Services Section PECO-COLR-L1R5 L1R5 Core Operating Limits Report Page 4, Rev. 0 Recirculation Pump Trip (RPTOOS) or inoper.able Steam Bypass System (TBVOOS). These two options represent the Equipment Out Of Service (EOOS) conditions.
i 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).
ARTS THERMAL 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-EOO." conditions.
These adjustments and multipliers are shown in Figures 11 through 16.
ROD BLOCK MONITOR SETPOINTS t
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 constanF data are shown in Table 1.
LINEAR HEAT GENERATION RATES The LHGR value for each fuel type for use in Technical Specification 3.2.4 is given in Table 3.
STEAM BYPASS SYSTEM OPERABILITY I
i 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.
