0 OS1 Attachment 9 Page 3 of 15 COLR for Shearon Harris Unit 1 Cycle 4 2.0 OPERATING LIMITS The cycle-specific parameter limits for the specifications listed in Section 1.0 are presented 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 3.0 ~

2.1 Moderator Tem erature Coefficient (Specification 3/4.1.1.3)

1. The Moderator Temperature Coefficient (MTC) limits are:

The Positive MTC Limit (ARO/HZP) shall, be less positive than

+5.0 pcm/'F for power levels up to 70X RTP with a linear ramp to 0 pcm/'F at 100X RTP.

The Negative MTC Limit (ARO/RTP) shall be less negative than

-49 pcm/'F.

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.'RO 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)

1. Fully withdrawn for all shutdown rods shall be 228 steps.

2.3 Control Rod Insertion Limits (Specification 3/4.1.3.6)

The control rod banks shall be limited in physical insertion as specified in Figure 1 of this attachment. Fully withdrawn for all control rods shall be 228 steps.

2.4 Axial Flux Difference (Specification 3/4.2.1)

1. The acceptable operational space for Relaxed Axial Offset Control (RAOC) operation is specified in Figure 2 of this attachment.

2 ~ The AXIAL FLUX DIFFERENCE (AFD) target band for Base Load operation is +5X.

3 ~ The APL for Base Load operation is 85X of RATED THERMAL POWERS PLP-106 Rev. 3 Page 68 of 80

3. K(Z) is specified in Figure 3 of this attachment.

4. W(z) Curves for RAOC Operation are specified in Figure's 4 through 6 of this attachment. These W(z) curves are sufficient to determine

'he 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/MTU through the use of three point interpolation.

5 ~ W(z) Curves'or Base Load Operation are specified in Figures 7 through 9 of this attachment. 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/MTU through the use of three point interpolation.
