PECO Fuel Management Section PECO-COLR-L1R4 L1R4 Core Operating Limits Report Page 3, Rev. 0 IllIRODUCTIOll A*ICLSUFMARY This repor t provides the cycle-specific parameter limits for: Average Planar Linear !!nat Generation Rate (APLHCR); Minimum Critical Pow'er Ratio (MCPR) ; Flow Adjustment Factor' (Ef ) ; Linear Heat Generation Ratn (LHGR); Rod Block Monitor flow biased upscale and high flow clamped setpoints; and Turbine Bypass Valve parameters fo: Limerick Generating titation Unit 1, Cycle 5, Reload 4. These values have been determined using NRC-approved methodology and are established such that all applicable limits of-the plant safety analynis 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 i Proceduce FM-105.

APLEGR LIMITS The limiting APLHGR value for the most limiting lattice (excluding _ natural uranium) of each fucl type as a function of average plansr exposure is given in Figuren 1 through 6. These figures aro-used when hand Lalculations are required as specified in Technical Specification 3.2.1. The reauction factor for uso during ning3e recirculation loop operatica is given in Table 1.

i MCPR LIMIIS The MCPR value for use in Technical Specification 3.2.3 for

.each fuel type la given in Figu es 7 through 13. The Kr core flow adjustment factor for use in Technical Specification 3.2.3 is given in Figure 14.

The MCPR. values shown in these figures are the bounding values for Increased Core Flow (up to 105% of rated core flow),

Rated Core Flow (100% of rated core flow), Extended Load Line

~

(down to 47% of rated core flov), Fecdwatar Temperature Reduction (up to 60 degrees f), power coastdown, and a combination of all of these-options. The curves;1aballed " Increased Core Flow and

'feedwater Temperature Reduction" represent bounding operating limit MCPAs for the ELL, RCF,-ICF, and ICF plus IHTR operatins

~

don alas. Curves are also provided for -inoperaolo Recirc Pump Trip or-inoperable Steam Bypass System.

The N value for the RBM flow bjased uy> scale and high flov clamped setpoints for use in Technical Specification 3.3.6 is given in Tabic 2.

LIJiEAR HEAT Sd;.11EBbTION RATFJ The LHGR value for use in Technical Specification 3.2.4 for each fuel type is given in Table 3

,1 STEAli BYPASS SYSTEM OPERABILITY 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 MCPR ljmitu for inoperable steam bypass system must be used.
