This report is prepared in accordance with Technical Specification 6.9.1.9 of Reference 1 , Preparation of this report was perf%med in accordance with Exetan Nuclear, Nuclear Fuel Management Procedure NF-AB- 120.
The data presented in this report is valid for all Licensed operating domains on the operating map, including:
Maximum Extended Load Line Limit down to 81% of rated core flow during full power operation hcreased Core Flow /KFj up to 1 lo%of rated core Bow Finai Feedwater Temperature Reduction (FTWTR) up to 105OF during cycle extension operation Feedwater Heater Out of Service CFWHOOSj up to 60°F feedwater tetnperature reduction at any time during the cycle prior to cycle extension.
Further infomation on the cycle specific analyses for Limerick 1 Cycle I t and the associated operating doniains discussed above is available in Reference 2.
Limerick Unit 1 Cycle 11 COLR COLK Limerick 1, Rev. 3 1 Page 8 The MAPLHGR limits provided in Tables 4-I through 4-8 are referenced in Technical Specifications 3.2. f .
The limiting MVLHGR value for the most limiting lattice (excluding natural uranium) of each fuel type as a function of average planar exposure is given in Tables 4- 1 through 4-7 (References 3 and 4). Tables 4-1 through 4-7 are used when hand calculations are required as specified in Technical Specification 3.2. I . For single loop operation, a reduction factor is used which is shown in Table 4-8 (Reference 2).
ARTS provides for povcec- and flow-dependent thermal limit multipliers, which allow for a more reliable administration of the MAPLHGK thermal limits. There are two sets of flow-dependentMAPLGHX multipliers for duaf-loop and single-loop operation (References 2, 5 and 8j. fn addition, there are atso two sets of power-dependent MAPLNGR multipliers for use with the Turbine Bypass Valves in service and TBVOOS conditions (Reference 13). Section 8.0 contains the conditions for Turbine Bypass Valve I Operability. The RilAPLHGR multipliers are shown in Figures 4-1 through 4-4 and are referred to by Technical Specification 3.21. Thermal Limit monitoring must be performed with the more limiting MAPLHGR limit resulting from the power- and flow-biased calculation. The W F A C ( P ) c w e s are independent of recirculation pump trip operability (Reference 13). 1

The Row-dependent adjustment MCPR(F) is sufficiently generic to apply to all fuel types and operating domains (References 2 and 8). In addition, there are also two sets of power-dependent MCPR multipliers for use with the Turbine Bypass Valves in service and TBVOOS conditions (Reference 13). Section 8.0 contains the conditions for Turbine Bypass I Valve Operability. These adjustments and muitipliers are shown in Figures 5-1 through 5-3 and are referred to by Technical Specification 3.2.3.
