PECO. Fuel Management Section PECO-COLR-L2R1 L2R1 Core. Operating Limits Report Page 3, Rev. O INTRODUCTION AND
SUMMARY
This report provides the cycle-specific parameter limits for: Average Planar Linear Heat Generation Rate (APLHGR); Minimum Critical Power Ratio (MOPR); Flow Adjustment Factor (K,); Linear Heat Generation-Rate (LHGhj. and Rod Block Monitor flow biased
)
upscale and high flow clamped setpoints for Limerick Generating i
Station Unit 2, Cycle 2.
These values have been determined using l
NRC-approved methodology and are established such-that all applicable limits of the pl&nt safety analysis are met.
l 1
This report _is submitted in accordance with Technical Specification 6.9.1 of. Reference (1).
Preparation of this report was performed in accordance with PECO Nuclear Group Procedure NP-11F122.
APLHGR LIMIT:
The limiting APLHGR value of each-fuel type as a function of AVERAGE PLANAR EXPOSUkE is given in Figures 1 through 6. Figures 1 through 6 are used as specified in Technical specification 3.2.1.
.The reduction factor for use during single recirculation loop. operation is given in Table 1.
MCPR LIMIT.
The MCPR. values for use.in Technical Specification 3.2.3 are
~
given in Figures 7 through 16.
The K, core flow adjustment factor-for-use in Technical Specification 3.2.3 is given in Figure 17.
EpD BLOCK MONITOR SETPOINI The N!value'for-theLRBM flow biased upscale and high flow
. clamped setpoints for-use in Technical Specification 3.3.6 is given in-Table 2.

OUALIFICATION FUEL __B_UNDLES The MCPR values for the Advanced Nuclear Fuel Inc. (ANF) and ABB Atom Inc. (ABB) Qualification Fuel Bundles-(QFBs) are found in Figures 13-16.
The MAPLHGR values for-use with the ABB and l
ANF QFBs are the values for the fuel type GE9B-P8CWC325-9GZ2-80M-150-T found in Figure 5.
The LHGR values are found in Table 3.
The MCPR and MAPLHGR values for the Gell QFBs are found in Figures 11-12-and 6 respectively.
The Gell-LHCR value-is found in Table 3.
