INTRODUCTION AND

SUMMARY

I 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 Upscala 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 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 Maximum 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 3 of the Limerick-1 Cycle 6 COLR addresses three issues related to thermal limits monitoring for the remainder of Cycle 6:

(a) validity of the original reload licensing analyses following the August, 1995 core reconfiguration, (b) incorporation of revised MAPLHGR limits to improve thermal margin, and (c) deletion of the previous revision of this document (Revision 2).

Further explanation of these issues follows.

(a)

The original reload licensing analyses for Cycle 6 were presented in Reference 2.

Discharge and replacement of failed fuel and a

subsequent core reconfiguration occurred during the August, 1995 Fuel Replacement Outage.

The Reference 9 analyses demonstrate that the original Reference 2 licensing analyses remain valid for the new core loading pattern.

(b)

New MAPLHGR data for fuel type D8CWB319 has been regenerated to provide improved therrral margin (Reference 4).

Figure 4 has been revised to reflect this new MAPLHGR curve.

(c)

Certain other data had been provided in Revision 2 of this document.

Revision 2 received PORC approval; however, it was later concluded that the new data in this revision would not immediately be required.

Therefore, for clarity, Revision 2 shall be deleted.

When this

PECO Encrgy Fuol cud Servicno Division PECO-COLR-L1R5 L1R5 Core Operating Limits Report Page 4, Rev. 3 thermal limit data is required it will be presented in a new revision to this document.

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 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 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).

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-EOOS conditions.

These adjustments and multipliers are shown in Figures 11

through 16.

l BOD BLOCK MONITOR SETPOINTS 1

l The ARTS RBM provides for power-dependent RBM trips to replace j

the previous flow-dependent trips.

The trip setpoints and applicable RBM signal filter time constant data are shown in Table 1.

l 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 The operability requirements for the steam bypass system for use in Techn3 cal 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-GENERATOR (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 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 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.
