1.0 INTRODUCTION
' i The Core Operating Limits Repon (COLR) for Plant Hatch Unit 2 Cycle 13 is prepared in '
accordance with the requirements of Technical Specification 5.6.5. The core operating limits presented herein were developed using NRC-approved methods (References 1 l
t.nd 2). Results from the fuel vendor's reload analyscs for the fuel in Unit 2 Cycle 13 are !
documented in References 3 and 4.
The following cycle-specific' core operating limits are included in this repon:

- b. Average Planar Linear Heat Generation Rate (APLHGR) -- Technical l

APLHGR LIMIT (Technical Specification 3.2.1)
The APLHGR limit for each fuel type is given by the applicable rated-power, rated-flow APLHGR limit taken from Figures 3-3 through 3-8, multiplied by the smaller of either:
- a. The flow-dependent multiplier, MAPFAC F, from Figure 3-1, or
- b. The power-dependent multiplier, MAPFACp, from Figure 3-2.
For the fuel types whose APLHGR limits are shown in Figures 1-3 through 3-8, the APLHGR limit shall be applied to each axial location in the fuel assembly.
As required by GESTAR (Reference 1), the hand-calculated APLHGR values for a multi-lattice (i.e., GE13-LUA or GE9B-P8DWB330-10GZ-80M-150-T) fuel must be less than or equal to the APLHGR limits shown in Figures 3-6 and 3-7. When APLHOR values are determined by the process computer, the lattice-dependent APLHGR limits are used.
Under these conditions, some axial locations may have APLHGR values exceeding the g
values shown in Figures 3-6 and 3-7.

- scram time, fuel type, number of operating recirculation loops, operability of the end-of-cycle recirculation pump trip (EOC-RPT) system, and operability of the turbine bypass
- valves.
i With both recirculation pumps in operation (TLO), the OLMCPR for each fuel type with
- various combinations of equipment operability, scram times, core flow and core power is l
- determined as follows
- !
i
- a. For 25% :s power < 30%, the OLMCPR is given in Figure 4-1.
i b. For power 2: 30%, the OLMCPR is the greater of either: l j 1) The flow-dependent MCPR limit determined from the applicable maximum core flow limit line of Figure 4-2, O or l
- 2) The product of the values from Figure 4-1 and the applicable Figures 4-3 and 4-4 as duermined by Table 4-1.
As stated in the note on Figures 4-3 and 4-4, with one recirculation pump operating (SLO), the calculated OLMCPR determined above is increased by 0.01.
In Figures 4-3 and 4-4, Option A scram time MCPR limits correspond to t = 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 determineA, Option A limits are to be used. Refer to Table 4-1 to determine the applicable set of fuel-type dependent curves.
