SHEARON HARRIS UNIT 1 CYCLE 4 CORE OPERATING LIMITS REPORT 1 of 15 (Rev. 1) 9iii2i008i PDR 5iiii2 ADOCK 05000400 P PDR

COI.R for SHEARON HARRIS U 1 CYCLE 4 LO CORE OPERATING LIMITS REPORT 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 Moderator Temperature Coefficient 3/4.1.3.5 Shutdown Rod Insertion Limit 3/4.1.3.6 Control Rod Insertion Limits 3/4.2.1 Axial Flux Difference 3/4.2.2 Heat Flux Hot Channel Factor - F<(Z) 3/4.2.3 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 MTC Limit (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 MTC Limit (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 All Rods Out HZP stands for Hot Zero THERMAL POWER RTP stands for RATED THERMAL POWER 2.2 Shutdown Rod Insertion Limit (Specification 3/4.1.3.5) 2.2.1 Fully withdrawn for all shutdown rods shall be 228 steps.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 Fully withdrawn for all control rods shall be 228 steps.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 AXIAL FLUX 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.

3 of 15 (Rev. l)

COLR for SHEARON HARRIS U 1 CYCLE 4 2.5 Heat Flux Hot Channel Factor - F<(Z) (Specification 3/4.2.2) 2.5.1 F<(Z) ( P

+ K(Z) for P ) 0.5 F<(Z) < Q 0.5

~ K(Z) for P < 0.5 where: P = THERMALPOWER RATED THERMAL POWER 2.5.2 = 2.45

~Q 2.5.3 K(Z) is specified in Figure 3.

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.
