1.0 INTHODUCTION .

The Core Operating Limits Report (COLR) for Plant flatch Unit 1 Cycle 17 is prepared [

in accordance with the requirements of Technical Speci0 cation 5.6.5. The core operating limits presented herein were developed using NRC approved methods (References 1 and 2)c Results flom the fuel vendor's reload analyses for the fuel in Unit 1 Cycle 17 are documented in References 3 through 8. >

3.0 APLilGit LIMITS (Technical Specification 3.2.1)

The APLilGR limit for each fuel type is given by the applicaNe rated power. rated flow APLil'R limit taken from Figures 3 3 through 3 9. multiplied by the smaller of either:

a. The flow dependent multiplier, M APFACr. from Figure 31, or

b. The power dependent multiplier, MAPFACp from Figure 3 2A or Figure 3 28. as deter.nined by Table 3 1.

For the fuel types whose APLilGR limits are shown in Figures 3 3 through 3 9 the APLilGR limit shall be applied to each axial location in the fuel assembly.

As required by GESTAR il(Reference 1),if the APLilGR values are hand calculated, all of the lattices in a multi lattice fuel bundle (i.e., GE9B P8DWB33010G7-80M 150 T, GE9B P8DWB331 10GZ-80M 150-T, GE13 P911TB327120Z-100M 146.T-LUA-RECON, GE9B P8DWB346-10GZ-80U 150 T.GE12 P10HSB3316GS.0/4G4.0100T-150-T, and GE9B P8DWB331 10GZ-80M 150-T-MAPL)must have APLilGR values less than or equal to the APLilGR limits shown in Figures 3 3,3 5,3 6. 3-7,3 8. and 3 9 respectively. When APLilGR values are determined by the process computer, the lattice-dependent APLilGR limits are used. Under these ;onditions, some axial locations may have APLllGR values exceeding the values shown in the figures.

, Plant liatch Unit I Cycle 17 Core Operating Limits Report 4.0 MCPR OPERATING LIMITS (Technical Specification 3.2.2)

The MCPR operating limit (OLMCPR) for each fuel type is a function of core power.

core flow, average scram time, number of operating recirculation loops, operability of the end of-cycle recirculation pump trip (EOC RPT) system, operability of the turbine bypass valves, and number of operating turbine pressure regulators.

With both recirculction pumps in operation (TLO), the OLMCPR for each fuel type with various combinations of equipment operability, scram times, core power and core flow is determined as follows:

a. For 25% 5 power < 30%, the power-dependent MCPR limit is given in Figure 4-1,

b. For power 2 30%, the OLMCPR is the greater of either:

1) The product of the appropriate value from Figure 4-2A or Figure 4 2B and the appropriate value from Figures 4-4A through 4-4D, as determined by Table 4-1, or O

2) The flow-dependent MCPR limit determined from the applicable maximum core flow limit line of Figure 4-3, With only one recirculation pump in operation (SLO), the OLMCPR for each fuel type is the TLO OLMCPR plus 0.01.

Operation with intermittent feedwater temperature reduction is included in the MCPR limits presented in Figures 4-4A through 4-4D.

In Figures 4-4A through 4-4D, Option A scram time MCPR limits correspond to i = 1.0, where t is determined from scram time measurements performed in accordance with Technical Specifications Surveillance Requirements 3.1.4.1 and 3.1.4.2. Option B values correspond to T = 0.0. For scram times between Option A and Option B, the MCPR limit for each fuel type corresponds to T. If t has not been determined Option A limits are to be used. Refer to Table 4-1 to detennine the applicable set of fuel-type dependent curves.
