SUMMARY

This report provides the cycle-specific parameter limits for: Average Planar Linear Heat Generation Rate (APLHGR); Minimum Critical Power Ratio (MCPR) ; Flow Adjustment Factor (Eg) ; Linear Heat Generation Rate (LHGR); and Rod Block Monitor flow biased upscale and high flow clamped setpoints for Limerick Generating

. Station Unit 1, Cycle 3, Reload 2. 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 of-Reference (1). Preparation of this report was_ performed in accordance with PECO_ Nuclear Group Procedure NP-11F122.

APLHGR LIMITS The limiting APLHGR 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 8. Figures 1 through 8 are used when hand calculations are required as specified in Technical Specification 3.2.1. The reduction factor for use during' single recirculation loop operation is given in Table 1.

MCPR LIMITS The MCPR value for use in Technical Specification 3.2.3 for each fuel type is given in Figures 9 through 12. The Kg core flow adjustment factor for use in-Technical Specification 3.2.3 is-given=in. Figure 13.

ROD BLOCK MONITOR'SETPOINTS 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 2.
