CYCLE 14 CORE OPERATING LIMITS REPORT

1.0 INTRODUCTION

This report provides the cycle specific limits for _

operation of the Fort Calhoun Station Unit 1 for Cycle 14 operation.' It_ includes limits for:

1.1 TM/LP LSSS 4 Pump Operation (PvAa) 1.2 Core Inlet Temperature (Tm) i 1.3 Power Dependent Insertion Limit (PDIL) 1.4 Allowable Peak Linear Heat Rate 1.5 Excore Monitoring of LHR 1.6 Planar Radial Peaking Factor (F nJ) r 1.7 Integrated Radial Peaking Factor (Fa) 1.8 DNB Monitoring 1.9 Fa /F9 7 versus Power Trade of f curve I

1.10 Refueling Baron Concentration ,

These limits are applicable for the duration of Cycle 14.

For subsequent-cycles the limits will be reviewed and revised as necessary. In addition, this report includes a number of cycle - specific coefficients used in-the generation of certain reaccor protective system trip setpoints or allowable increases in radial peaking factors.

This report has been prepared in accordance with the-requirements of_ Technical Specification 5.9.5. The core operating limits have been developed using-the NRC methodologies listed in Technical Specification 5.9.5.b.

2.0 CQEE OPERATING LIMITS The values and limits presented within this section have been derived using the NRC - approved methodologies listed in Technical Specification 5.9.5. All values and limits in this section apply to Cycle 14 operation. Cycle 14 must be operated within the bounds of_these. limits and all others specified in the Technical Specifications.

-The maximum core inlet temperature (T i w) for Cycle 14 shall not exceed 543*F.

This limit is not applicable during either.a thermal power ramp in excess of 5% of rated thermal power per minute or a' thermal power step greater than 10% of rated thermal power.

5.0 POWER DEPE!{DJJU' INSERTION LIMIT The power dependent insertion limit is defined in Figure 2 for Cycle 14 operation.

TECHNICAL DATA BOOK PROCEDURE PAGE 7 OF 13 6.0 LINEAR HEAT RATE The allowable peak linear heat rate vs. burnup for Cycle 14 is 15.5 kW/ft for less than or equal to 7770 MWD /T, and 14.4 kW/ft for greater than 7770 MWD /T. The allowable peak linear heat-rate for Cycle 14 is shown in Figure 3.

7.0 EXCORE MONITORING OF LHR The allowable operation for power versus axial shape index for monitoring of LHR with excore detectors for Cycle 14 is shown_in Figure 4.

8.0 PEAKING FACTOR LIMITS The maximum full power values for the unrodded planar radial peaking factor ( F,yI ) and integrated radial peaking - factor Fa') -

are shown in Table 2.

1.85 Fa* l 79 9.0 DNB MONITORING The limits for DNB as a function of axial shape index and core power is snown in Figure 5.

Core power shall be maintained within the limits established by-the Better Axial Shape Selection System (BASSS) for CEA insertion of the lead bank of c65% (i.e., greater than or equal to 44.1 inches withdrawn) when BASSS is operable, or within the limits of Figure 5.

i 10.0 En M a AND CORE POWER LIMITATIONS Core power limitations versus Fa and Fnt are shown in Figure 6, i

11.0 REFUELING BORON CONCENTRATION The refueling baron concentration must be maintained with a l

boron concentration of at least 1700 ppm in the Reactor Coolant System to ensure a shutdown margin of not less than 5% with all CEAs withdrawn.
