COI.R for SHEARON HARRIS U 1 CYCLE 4 LO CORE OPERATING LIMITSREPORT This Core Operating Limits Report (COLR) for Shearon Harris Unit 1 Cycle 4 has been prepared in accordance with the requirements of Technical Specification 6.9.1.6 The Technical Specifications affected by this report are listed below:

3/4.1.1.3 3/4.1.3.5 3/4.1.3.6 3/4.2.1 3/4.2.2 3/4.2.3 Moderator Temperature Coefficient Shutdown Rod Insertion Limit Control Rod Insertion Limits Axial Flux Difference Heat Flux Hot Channel Factor - F<(Z)

Nuclear Enthalpy Rise Hot Channel Factor-F, 2 of 15 (Rev. l)

COLR for SHEARON HARRIS U 1 CYCLE 4 2.0 OPERATING LIMITS The cycle-specific parameter limits for the specifications listed in Section 1.0 are prcseni<<d in the following subsections.

These limits have been developed using the NRC-approved methodologies specified in Technical Specification 6.9.1.6 and given in Section 3.

2.1 Moderator Tem erature Coefficient (Specification 3/4.1.1.3) 2.1.1 The Moderator Temperature Coefficient (MTC) limits are:

The Positive MTCLimit(ARO/HZP) shall be less positive than +5.0 pcm/'

for power levels up to 70% RTP with a linear ramp to 0 pcm/'F at 100olc RTP.

The Negative MTCLimit(ARO/RTP) shall be less negative than -49 pcmi'.

2.1.2 The MTC Surveillance limit is:

The 300 ppm/ARO/RTP-MTC should be less negative than or equal to

-41.5 pcm/'F.

where: ARO stands for AllRods Out HZP stands for Hot Zero THERMALPOWER RTP stands for RATED THERMALPOWER 2.2 Shutdown Rod Insertion Limit (Specification 3/4.1.3.5) 2.2.1 Fully withdrawn for all shutdown rods shall be 228 steps.

2.3 Control Rod Insertion Limits (Specification 3/4.1.3.6) 2.3.1 The control rod banks shall be limited in physical insertion as specified in Figure 1. Fully withdrawn for all control rods shall be 228 steps.

2.4 Axial Flux Difference (Specification 3/4.2.1) 2.4.1 The acceptable operational space for Relaxed Axial Offset Control (RAOC) operation is specified in Figure 2.

2.4.2 The AXIALFLUX DIFFERENCE (AFD) target band for Base Load operation is +5%.

2.4.3 The APL"0 for Base Load operation is 85% of RATED THERMAL POWER.

2.5.4 W(z) Curves for RAOC Operation are specified in Figures 4 through 6.

These W(z) curves are sufficient to determine the RAOC W(z) versus core height for Cycle 4 burnups through the end of full power reactivity plus a power coastdown of up to 1219 MWD/MTUthrough the use of three point interpolation.

2.5.5 W(z) Curves for Base Load Operation are specified in Figures 7 through 9.

These W(z) curves are sufficient to determine the Base Load W(z) versus core height for Cycle 4 burnups through the end of full power reactivity plus a power'coastdown of up to 1219 MWD/MTUthrough the use of three point interpolation.
