1.0 INTRODUCTION

The Core Operating Limits Report (COLR) for Plant Hatch Unit 2 Cycle 25 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 6). Results from the reload analyses for the fuel in Unit 2 Cycle 25 are documented in References 2 through 4. 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 allow operation with dome pressure down to 40 psi below nominal. Also included in this report are the licensed scram setpoints 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 2 operation. TABLE 1-1 Main Turbine Bypass System Operability .. *sysiern . ! . .

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 Table 3-2, 2) The power-dependent MCPR limit, MCPRp, as determined by Table 3-3. b. For core power> 45%, the greater of either: 1) MCPRF, as determined by Table 3-2, 2) The product of the power-dependent multiplier, Kp, as determined by Table 3-4, and the rated-power OLMCPR, as determined by Table 3-5. 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 +/-1 O 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. 14 Plant Hatch Unit 2 Cycle 25 Non-Proprietary Information Core Operating Limits Report Version 1.0 In the 3-4A and 3-48 figures, Option A scram time OLMCPRs 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 rated-power OLMCPR corresponds to 't. If 't has not been determined, Option A limits must be used. The average scram time of the control rods, 't , is defined as: = 0, OR , whichever is greater. where: '!A = 1.08 sec (Technical Specification 3.1.4, Table 3.1.4-1, scram time limit to notch 36).

The flow-dependent multiplier, LHGRFACF, as determined by Table 4-2, b. The power-dependent multiplier, LHGRFACp, as determined by Table 4-3. 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 +/-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 LHGR operating limit defined in this section.
