1.0 INTRODUCTION

The Core Operating Limits Report (COLR) for Plant Hatch Unit 1 Cycle 22 is prepared inaccordance with the requirements of Technical Specification 5.6.5. The core operatinglimits presented herein were developed using NRC-approved methods (References 1, 2,3, and 4). Results from the reload analyses for the fuel in Unit 1 Cycle 22 aredocumented in References 3, 4, 5 and 6.

The following core operating limits are included in this report:

a. Average Planar Linear Heat Generation Rate (APLHGR) - Technical Specification3.2.1

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 1operation with equipment out of service.

3.0 MCPR OPERATING LIMITS (Technical Specification 3.2.2)

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

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

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

b. For power Ž 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 OLMCPR is the TLO OLMCPRplus 0.02.

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

In Figures 3-4A and 3-4B, Option A scram time OLMCPRs correspond to r = 1.0, whereX is determined from scram time measurements performed in accordance with TechnicalSpecifications Surveillance Requirements 3.1.4.1 and 3.1.4.2. Option B valuescorrespond to X = 0.0. For scram times between Option A and Option B, the rated-power, rated-flow OLMCPR corresponds to T. If X has not been determined, Option Alimits are to be used.

6 Version 1


The average scram time of the control rods, T, is defined as:

Tave - TB

= 0, or , whichever is greater.TA - TB

where: TA = 1.08 sec (Technical Specification 3.1.4, Table 3.1.4-1, scram timelimit to notch 36).

112

TB= + 1.65 * a *[ Ni

EMei-1

where: j = 0.822 sec (mean scram time used in the transient analysis).

a = 0.018 sec (standard deviation of g).

n

Tave = 'NI

ZNi

where: n = number of surveillance tests performed to date in the cycle.

N. = number of active control rods measured in the ith surveillance test.

Tj = average scram time to notch 36 of all rods in the ith surveillance test.

N. = total number of active rods measured in Technical SpecificationsSurveillance Requirement 3.1.4.1.

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 theapplicable rated-power, rated-flow LHGR limit taken from Figure 4-3 or 4-4, multiplied bythe 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 nogadolinium) and the most limiting gadolinium-bearing rods for GE13 and GE14 fueltypes, respectively. Other gadolinium-bearing rods may have proprietary LHGR limitswhich lie between these two curves. Compliance with the proprietary limits will bemonitored by the plant's process computer, in which case some gadolinium-bearing rodsmay operate at power levels above the more restrictive limits shown on these curves.
