SUMMARY

The CORE OPERATING LIMITS REPORT is the Clinten-specific document that provides the values of the AVERAGE PLANAR LINEAR HEAT CENERATION RATE (APLHCR) limits, the core flow dependent MINIMUM CRITICAL P0k'ER RATIO (MCPR) limits (MCPR f ), the thermal power dependent MCPP, limits (MCPR p ), and the 1.INEAR HEAT GENERATION RATE (LHCR) litnits for the current operating reload cycle, These cycle-specific core operati..o _

limits are determined for each reload cycle in accordance with Technical Specification 6.9.1.9. Per the Technical Specification, these values have been deterrained using NRC - approved methodology and are established such that all applicable limits of the plant safety analysis are met. Plant operatton within these operating ,

liinits is addressed in the applicable Technical Specifications.

A

LIMITS APPLICABL/ TO TECIINICAL SPECIFICATION 3/4.2.1 POk'ER lilSTRIBUTION LIMITS AVERACE PLANAR LINEARJIqT GENERATION RATE All AVERAGE PLANAR LINEAR llEAT GENERATION RATES (APulGRs) for each type of fuel as a function of axial location and AVERAGE PIANAR EXPOSURE. shall not exceed limits based on applicable MAPulGR limit values which have been approved for the particular fuel type and axial region (lattice). The MAPLilGR limits for each fuel type are contained in Referance 4 k' hen manual calculations are required, all APUlGRs for each type of fuel as a function of AVERAGE PIANAR EXPOSURE shall not exceed the limits as determined below:

a. During two-recirculation loop operation - the limits shown in Figares 2.1-3 through 2,1-7 multiplied by the smaller of either the flow-dependent MAPulGR factor (MAPFACr) of Figure 2.1-1 or the power-dependent MAPulGR factor (MAPFAC p ) of Figure 2.1-2.
b. During single recirculation loop operation - the limits shown in Figures 2.1-3 through 2.1-7 nultiplied by the smallest of MAPFACg, MAPFACp or a factor of 0.78.
