Callaway Cycle 14 COLR Rev. 2 l CALLAWAY CYCLE 14 CORE OPERATING LIMITS REPORT (Revision 2) l May 2004

Callaway Cycle 14 COLR Rev. 2 l 1.0 CORE OPERATING LIMITS REPORT This Core Operating Limits Report (COLR) for Callaway Plant Cycle 14 has been prepared in accordance with the requirements of Technical Specification 5.6.5.

The Core Operating Limits affecting the following Technical Specifications are included in this report.

3.1.1, 3.1.4, 3.1.5, 3.1.6, 3.1.8 Shutdown Margin 3.1.3 Moderator Temperature Coefficient 3.1.5 Shutdown Bank Insertion Limits 3.1.6 Control Bank Insertion Limits 3.2.1 Heat Flux Hot Channel Factor 3.2.2 Nuclear Enthalpy Rise Hot Channel Factor 3.2.3 Axial Flux Difference 1

Callaway Cycle 14 COLR Rev. 2 1 2.0 OPERATING LIMITS The cycle-specific parameter limits for the specifications listed in Section 1.0 are presented in the subsections which follow. These limits have been developed using the NRC-approved methodologies specified in Technical Specification 5.6.5.

2.1 Shutdown Margin (Specifications 3.1.1, 3.1.4, 3.1.5. 3.1.6, and 3.1.8) 2.1.1 The Shutdown Margin in MODES 1-4 shall be greater than or equal to 1.3% Akfk.

2.1.2 The Shutdown Margin prior to blocking Safety Injection below P-Il in MODES 3 and 4 shall be greater than 0% Ak/k as calculated at 2000F.

2.1.3 The Shutdown Margin in MODE 5 shall be greater than or equal to 1.0%o Ak/k.

2.2 Moderator Temperature Coefficient (Specification 3.1.3) 2.2.1 The Moderator Temperature Coefficient shall be less positive than the limits shown in Figure 1. These limits shall be referred to as upper limit.

The Moderator Temperature Coefficient shall be less negative than -47.9 pcm/"F.

This limit shall be referred to as the lower limit.

2.2.2 The MTC 300 ppm surveillance limit is 40.4 pcmflF (all rods withdrawn, Rated Thermal Power condition).

2.2.3 The MTC 60 ppm surveillance limit is -45.5 pcmPF (all rods withdrawn, Rated Thermal Power condition).

The shutdown banks shall be withdrawn to at least 225 steps.

2.4 Control Bank Insertion Limnits (Specification 3.1.6) 2.4.1 Control Bank insertion limits ae specified by Figure 2.

2.4.2 Control Bank withdrawal sequence is A-B-C-D. The insertion sequence is the reverse of the withdrawal sequence.

2.4.3 The difference between each sequential Control Bank position is 115 steps when not fully inserted and not fully withdrawn.

  • K(Z) for P < 0.5 0.5 THERMAL POWER where: P =

RATED THERMAL POWER 2.5.1 FQRWt = 2.45 for all Cycle 14 burnups less than 8000 MWD/MTU, and FQRw = 2.50 for all Cycle 14 burnups greater than or equal to 8000 MWD/MTU.

2.5.2 K(Z) is provided in Figure 3.

2.5.3 The W(z) functions that are to be used in Technical Specification 3.2.1 and Surveillance Requirement 3.2.1.2 for determining FQW(z) are shown in Figures 4 through 8.

The W(z) values have been determined for several burnups up to 18000 MWD/MTU in Cycle 14. This permits determination of W(z) at any cycle burnup up to 18000 MWD/MTU through the use of three point interpolation. For cycle burnups greater than 18000 MWD/MTU, use of 18000 MWD/MTU W(z) values without interpolation or extrapolation is conservative. The W(z) values were determined assuming Cycle 14 operates with RAOC strategy. Also included is a W(z) function that bounds the W(z) Curve for all Cycle 14 burnups. Use of the bounding W(z) curve will be conservative for any Cycle 14 burnup; however, additional margin may be gained by using the burnup dependent W(z) values.

The W(z) values are provided for 73 axial points within the core height boundaries of 0 and 12 feet at intervals of 0.167 feet.

Table A.1 shows the burnup dependent FQ penalty factors for Cycle 14. These values shall be used to increase FQW(z) when required by Technical Specification Surveillance Requirement 3.2.1.2. A 2% penalty factor should be used at all cycle burnups that are outside the range of Table A.1.
