Nuclear Regulatory Commission ATTN: Document Control Desk Washington, D. C. 20555-0001 Edwin I. Hatch Nuclear Plant Unit I Cycle 21 Core Operating Limits Report (COLR), Revision 2 Ladies and Gentlemen:

In accordance with Technical Specification 5.6.5, Southern Nuclear Operating Company (SNC) hereby submits the Edwin I. Hatch Nuclear Plant Unit I Cycle 21 Core Operating Limits Report, Revision 2.

This revision is needed to reflect the fact that power distribution limits monitoring will be required at core thermal power levels greater than or equal to 24% of rated core thermal power when the 1.5% Thermal Power Optimization (TPO) uprate is implemented on Unit 1.

Also, due to recent changes in the Oscillation Power Range Monitor (OPRM) setpoints on Unit 1, Revision 2 of the Hatch-l Cycle 21 COLR is being updated to include additional Period Based Detection Algorithm (PBDA) amplitude setpoints in Section 4.0.

This letter contains no NRC commitments. If you have any questions, please advise.

Sincerely, H. L. Sumner, Jr.

Plant Hatch Unit 1 Cycle 21 Core Operating Limits Report

1.0 INTRODUCTION

The Core Operating Limits Report (COLR) for Plant Hatch Unit 1 Cycle 21 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 (Reference 1). Results from the reload analyses for the fuel in Unit 1 Cycle 21 are documented in References 2, 3, and 4. These analyses are supplemented for the mid-cycle Thermal Power Optimization (TPO) uprate by References 8 and 9. Results from the most recent cycle independent analyses are documented in Reference 5. Revised APLHGR limits for GE1 3 fuel are documented in References 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. Maximum allowable scram setpoints for the Period Based Detection Algorithm (PBDA) in the Oscillation Power Range Monitor (OPRM) system.

From a fuel thermal limits perspective, the following limitations are placed on Unit 1 operation with equipment out of service.

Equipment/ Condition Limitation EOC-RPT Out of Service AND Not analyzed Turbine Bypass Valves Inoperable Simultaneously Single-Loop Operation (SLO)

• s 2000 MWt

• < 56% Core Flow 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).

1 Revision 2

Plant Hatch Unit 1Cycle 21 Core Operating Limits Report 2.0 APLHGR LIMITS (Technical Specification 3.2.1)

The APLHGR limit for each fuel assembly is the applicable rated-power, rated-flow APLHGR limit taken from Figures 2-3 through 2-8, multiplied by the smaller of either:

a. The flow-dependent multiplier, MAPFACF, from Figure 2-1, or

b. The power-dependent multiplier, MAPFACp, as determined by Table 2-1.

Since every assembly in the core contains more than one enriched lattice, GESTAR-I1 (Reference 1) requires that the appropriate APLHGR limit from Figures 2-3 through Figures 2-8 be applied to every axial location in the fuel assembly, when APLHGR values are hand-calculated. The limits shown in those figures are the values for the most limiting enriched lattice in each fuel bundle as a function of average planar exposure.

When APLHGR values are determined by the process computer, the lattice type-dependent APLHGR limits are used. Under these conditions, some axial locations may have APLHGR Values exceeding the values shown in the figures.

Plant Hatch Unit 1 Cycle 21 Core Operating Limits Report 3.0 MCPR OPERATING LIMITS (Technical Specification 3.2.2)

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

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

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

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 MCPR limit as determined by Table 3-1A or 3-1 B.

With only one recirculation pump in operation (SLO), the OLMCPR for each fuel type is the TLO OLMCPR plus 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 34A through 3-4E, Option A scram time MCPR limits correspond to X=

1.0, where r 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 r = 0.0. For scram times between Option A and Option B, the MCPR limit for each fuel corresponds to x. If Xrhas not been determined, Option A limits are to be used. Refer to Table 3-1A or 3-1 B to determine the applicable set of fuel-type dependent curves.

Plant Hatch Unit 1 Cycle 21 Core Operating Limits Report 4.0 PBDA AMPLITUDE SETPOINT The amplitude trip setpoint in the Period Based Detection Algorithm in the OPRM system shall not exceed the values reported in the Table below. This applies to instruments 1C51 K615 A, B, C, and D. These are the nominal trip setpoint values, not the allowable values. Projected Figure of Merit (FOM) value(s) throughout the cycle will be supplied by the Hatch Core Analysis Group.
