1.0 INTRODUCTION

The Core Operating Limits Report (COLR) for Plant Hatch Unit 2 Cycle 19 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, 2, 3, 4, and 5). Results from the reload analyses for the fuel in Unit 2 Cycle 19 are documented in References 3, 4, 5, 6, and 7.

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 From a fuel thermal limits perspective, the following limitations are placed on Unit 2 operation.

Equipment / Condition Limitation EOC-RPT Out of Service AND Not analyzed Turbine Bypass Valves Inoperable Simultaneously High Pressure Feedwater Heater(s) Out of Service AND Not analyzed Pressure Regulator Inoperable Simultaneously

• 2000 MWt Single-Loop Operation (SLO) *

• 56% Core Flow Option B Scram Speeds Pressure Regulator Inoperable Met (in place)

Also included in this report are the maximum allowable scram setpoints for the Period Based Detection Algorithm (PBDA) in the Oscillation Power Range Monitor (OPRM).

Plant Hatch Unit 2 Cycle 19 Core Operating Limits Report 3.0 MCPR OPERATING LIMITS (Technical Specification 3.2.2)

The MCPR operating limit (OLMCPR) is a function of core power, core flow, average scram time, number of operating recirculation loops, EOC-RPT system status, operability of the turbine bypass valves, and whether both pressure regulators are operable.

With both recirculation pumps in operation (TLO), the OLMCPR is determined as follows:

a. For 24% < power < 28%, the power-dependent MCPR limit, MCPRp, as determined by Table 3-1.

b. For power 2 28%, the OLMCPR is the greater of either:

1) The flow-dependent MCPR limit, MCPRF, from Figure 3-2, or

2) The product of the power-dependent multiplier, Kp, and the rated-power, rated-flow OLMCPR, as determined by Table 3-1.

With only one recirculation pump in operation (SLO), the OLMCPRs in Figures 3-1A, 3-1B, 3-4A and 3-4B must be increased by 0.02.

These limits apply to all modes of operation with intermittent feedwater temperature reduction, as well as operation with normal feedwater temperatures.

In Figures 3-4A and 3-4B, Option A scram time OLMCPRs correspond to T = 1.0, where Xis 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 X= 0.0. For scram times between Option A and Option B, the rated-power, rated-flow OLMCPR corresponds to T. If Xhas not been determined, Option A limits are to be used.

Plant Hatch Unit 2 Cycle 19 Core Operating Limits Report 4.0 LHGR LIMITS (Technical Specification 3.2.3)

The LHGR 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 Figure 4-3 or 4-4, multiplied by the smaller of either:

a. The flow-dependent multiplier, LHGRFACF, from Figure 4-1, or

b. The power-dependent multiplier, LHGRFACp, as determined by Table 4-1.

Figures 4-3 and 4-4 show the LHGR limits for both U02 rods (which contain no gadolinium) and the most limiting gadolinium-bearing rods for GE13 and GE14 fuel types, respectively. Other gadolinium-bearing rods may have proprietary LHGR limits which lie between these two curves. Compliance with the proprietary limits will be monitored by the plant's process computer, in which case some gadolinium-bearing rods may operate at power levels above the more restrictive limits shown on these curves.
