Core Operating Limits Report 1.0 : INTRODUCTION The Core Operating Limits Report (COLR) for Plant Hatch Unit 1 Cycle 17 is prepared in accordance with the requirements of Technical Specification 5.6.5. The production of this document is documented in a DRF under QA No. NFS-96-029. The core operating limits presented herein were developed using NRC-approved methods (References 1 and 2). Results from the fuel vendor's reload analyses for the fuel in Unit 1 Cycle 17 are documented in References 3,4, and 5. l-The following cycle-specific core operating limits are included in this report:

a. Control Rod Block Instrumentation - Technical Specification 3.3.2.1
b. Average Planar Linear Heat Generation Rate (APLHGR) - Technical  ;

Specification 2.1

c. Minimum Critical Power Ratio (MCPR) - Technical Specifications 3.2.2 and 3.3.2.1 i
d. APRM Flow Biased Simulated Thermal Power' High -- Technical Specifications l Surveillance Requirement 3.3.1.1.14 2.0 ROD BLOCK MONITOR (Technical Specification 3.3.2.1) l Both Rod Block Monitor (RBM) channels shall be operable as specified in Technical Specification 3.3.2.1 and when:

1

a. Thermal Power is 2 29% and < 90% of Rated Thermal Power, and MCPR is < 1.70; l or
b. Thermal Power is 2 90% of Rated Thermal Power, and MCPR is < l.40.

Plant Hatch Unit 1 Cycle 17 j Core Operating Limits Report ,e 3.0 APLHGR LIMIT (Technical Specification 3.2.1) l l

The APLHGR limit for each fuel type is given by the applicable rated-power, rated-flow j APLHGR limit taken from Figures 3-3 through 3-8, multiplied by the smaller of either:

. a. The flow-dependent multiplier, MAPFACF, 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 3-3 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 multip lattice fuel (i.e., GE9-330, GE9-331, GE13-LUA, GE9-346, and GE12-331) must be less than or equal to the APLHGR limits shown in Figures 3-3,3-5,3-6,3-7, and 3-8, respectively. When APLHGR 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 values shown in Figures 3-3,3-5,3-6,3-7, and 3-8.

Core Operating Limits Report 4.0 ' MCPR LIMIT (Technical Specification 3.2.2) - l The MCPR operating limit (OLMCPR) is a function of core power, core flow, average 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.

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 determined as follows:

a. For 25% $ power < 30%, the OLMCPR is given in Figure 4-1.
b. For power 2 30%, the OLMCPR is the greater of either:
1) The flow-dependent MCPR limit determined from the applicable maximum core flow limit line of Figure 4-2, or L
2) The product of the values from Figure 4-1 and the applicable Figures 4-3 through )

4-6 as determined by Table 4-1. l As stated in the note on Figures 4-3 through 4-6, with one recirculation pump operating l (SLO), the calculated OLMCPR determined above is increased by 0.01. i In Figures 4-3 through 4-6, Option A scram time MCPR limits correspond to t = 1.0, l 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. IfI has not been determined, Option A limits are to  !

l be used. Refer to Table 4-1 to determine the applicable set of fuel-type dependent curves.
