SUMMARY

This report provides the cycle-sgecific parameter limits for: Average Planar Unear Heat Generation Rate (APLHGR); Minimum Critical Power Ratio (MCPR); Flow Adjustment Factor (K); i Linear Heat Generation Rate (LHGR); and Rod Block Monitor flow biased upscale and high flow clamped setpoints for Limerick Generating Station Unit 2, Cycle 2. These values have been determined using NRC'-approved methodology and are estabDshed such that all applicable limits of the plant safety analysis are met. .

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 Fuel Management Section Procedure FM-105.

APLHGR LIMIT The limiting APLHGR vMue ot each fuel type as a function of AVERAGE PLANAR EXPOSURE is given in Figt augh 6. Figures 1 through 6 are used as specified in Technical Specification 3.2.1. The reduction . .: tor for use during single recirculation loop operation is given in Table 1. These values are documented in Reference (5).

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.

These values are documented in Reference (2), an additional 0.01 was added to the EOC-2000 MWD /st to EOC MCPR Operating Limits for all GE fueltypes per Reference (7). ,

The MCPR values given are the bounding values for increased Core Flow (up to 105% flow),

Feedwater Temperature Reduction (up to 70 degrees F at rated power). Power Coastdown ;to 60% (

prwer or 321*F, whichever comes first, with FFWTR or 40% power without FFWTR), and a csr.bination of all of these opons. Curves are also provided forinoperable Recire Pump Trip or

  • inoperable Steam Bypass System. These operating domain limits are documented in References (2), (6), and (7),

b ROD BLOCK MONITOR SETPOINT The N value for the RBM flow biased upscale and high flow clamped setpoints for use in Technical Specification 3.3.6 is given in Table E. These values are documented in Reference (2).

l

i FECo Fuel Management Section PECO-COLR L2R1 L2R1 Core Operating Umits Report Page 4, Rev. 4 -

LINEAR HEAT GENERATION RATE The LHGR value for use in Technical Specifnation 3.2.4 is gi m able 3. These values are documented in References (3), (4), and (6).

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 e.re found in Table 4. If these requirements cannot be met the MCPR limits for -

inoperable steam bypass system must be used. These values are documented in References (2) and (6).

QUALIFICATION FUEL DUNDLES The MCPR values for the Advanced Nuclear Fuel Inc. (ANF) and ABB Atom inc. (ABB)

Qualification Fuel Bundles (OFBs) are founu in Figures 13-16. Appropriate corrections were made to the ANF and ARB QFBs to account for the increase in the GE fuel type limits per Reference (7).

The MAPLHGR " 'ues for use with the ABB and ANF OFEs are the values for the fuel type GE9B P8CWB325-9GZ2-80M-150 T found in Figure 5. The LHGR values are found in Table 3. The MCPR and MAPLHGR values for the GE11 OFBs are found in Figures 11-12 and 6 respectively.

The GE11 LHGR value is found in Table 3. These values are documented in References (2), (3),

and (4). ,
