==1.0     INTRODUCTION==

The Core Operating Limits Report (COLR) for Plant Hatch Unit 1 Cycle 29 is prepared in accordance with the requirements of Technical Specification 5.6.5. The core operating limits presented herein were developed using NRG-approved methods (References 1 through 8).
Results from the reload analyses for the fuel in Unit 1 Cycle 29 are documented in References 2 through 4.
GNF2 fuel limits in this report are applicable to ARMOR and Ironclad Lead Test Assemblies (References 7 and 8).
The following core operating limits are included in this report:
: a. Average Planar Linear Heat Generation Rate (APLHGR) - Technical Specification 3.2.1
: b. Minimum Critical Power Ratio (MCPR) - Technical Specification 3.2.2
: c. Linear Heat Generation Rate (LHGR) - Technical Specification 3.2.3 This report includes reduced thermal limit ratios which may be used in conjunction with the standard core operating limits to all<;>w operation with dome pressure down to 40 psi below nominal. Also included in this report is the licensed scram setpoint for the Period Based Detection Algorithm (PBDA) in the Oscillation Power Range Monitor (OPRM).
Based upon the reload analyses for this cycle, the following operability requirement is defined for Unit 1 operation.

For both two loop operation (TLO) and single loop operation (SLO), the APLHGR limit for each six inch axial segment of each fuel assembly in the core is the applicable fuel-type-specific APLHGR limit in Figure 2-2 multiplied by the fuel-type-specific flow-dependent multiplier, MAPFACF, taken from either:
: a. Figure 2.-1A for GE14C fuel
: b. Figure 2-1 B for GNF2 fuel 9

The MCPR operating limits (OLMCPRs) for each fuel type are a function of core power, core flow, average scram time, number of operating recirculation loops, EOC-RPT system status, operability of the main turbine bypass system, the status of the main turbine pressure regulator system, and cycle exposure. Cycle exposures are defined in Table 3-1.
The OLMCPRs for both two loop operation (TLO) and single loop operation (SLO) are determined as follows:
: a. For 24% ::; core power::; 45%, the greater of either:
: 1) The flow-dependent MCPR limit, MCPRF, as determined by Figure 3-1,
: 2) The power-dependent MCPR limit, MCPRP, as determined by Table 3-2.
: b. For core power> 45%, the greater of either:
: 1) MCPRF, as determined by Figure 3-1 OR
: 2) The product of the power-dependent multiplier, KP, as determined by Table 3-3, and the rated-power OLMCPR, as determined by Table 3-4.
These limits apply to all operating conditions with normal feedwater temperature, as well as with feedwater temperature reduction.
These limits apply to operation with vessel dome pressure within +/- 10 psi of nominal. pressure, as defined by the Region I pressure band shown in Figure 5-1. With all equipment in service or with the EOC-RPT system out of service, operation with vessel dome pressure down to 40 psi below nominal is licensed provided the additional restrictions identified in Section 5.0 are applied with the MCPR operating limit defined in this section.

Option B values correspond to T = 0.0. For scram times between Option A and Option B, the rated-power OLMCPR corresponds to T. If T has not been determined, Option A limits must be used.

For both two loop operation (TLO) and single loop operation (SLO), the LHGR operating limit for each six inch axial segment of each fuel rod in the core is the applicable rated-power, rated-flow LHGR limit taken from Table 4-1 multiplied by the smaller of either:
: a. The flow-dependent multiplier,.LHGRFACF, as determined by Table 4-2, OR
: b. The power-dependent multiplier, LHGRFACp, as determined by Figure 4-2.
Table 4-1 shows the exposure-dependent LHGR limits for all fuel types in the core, as a function of initial gadolinium concentration in a six inch segment of a fuel rod. For exposures between the values shown in Table 4-1, the LHGR limit is based on linear interpolation. For illustration purposes, Figures 4-3A and 4-38 show the LHGR limits for fuel segments with the lowest (U02) and highest (U02+Gd203) initial Gd concentrations.
These limits apply to operation with vessel dome pressure within +/- 1O psi of nominal pressure, as defined by the Region I pressure band shown in Figure 5-1. With all equipment in service or with the EOC-RPT system out of service, op_eration with vessel dome pressure down to 40 psi below nominal is licensed provided the additional restrictions identified in Section 5.0 are applied with the LHGR operating limit defined in this section.

For operation in each of these regions, the following restrictions apply:
: a. For Region I operation:
The core operating limits from Sections 2.0 through 4.0 are applicable.
: b. For Region II and Region Ill operation:
: 1) The OPRM System must be operable
: 2) The core operating limits from Section 2.0 are applicable
: 3) The MFLCPR and MFLPD thermal limit ratios must remain below the maximum values determined by Table 5-1.
The MFLCPR and MFLPD thermal limit ratios are defined in terms of the core operating limits defined in Section 3.0 and Section 4.0.
The MFLCPR thermal limit ratio is the most limiting (maximum) value of the Fraction of Limiting Critical Power Ratio (FLCPR) in the core. The FLCPR is defined for each fuel assembly in the core as:
MCPRumit FLCPR         =
Fuel Assembly Minimum Critical Power Ratio where:      MCPRumit      =    MCPR operating limit defined in Section 3.0 47

The FLPD is defined for each six inch axial segment of each fuel rod in the core as:
Peak kW/ft power generated in a fuel rod segment FLPD              =
LHGRumit where:          LHGRumit          =   LHGR operating limit defined in Section 4.0 The licensed equipment conditions for operation with dome pressures in Region 11 and Region Ill of Figure 5-1 are defined in Table 5-1.
