1 OS2 Attachment 9 Page 2 of 14 Shearon Harris Unit 1 Cycle 5 Core Operating Limits Report - Rev. 0 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)

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 70% RTP with a linear ramp to O,pcm/'F at 100% 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: 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)

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 Fully withdrawn for all shutdown rods shall be 228 steps.

2.3 Control Rod Insertion Limits (Specification 3/4.1.3.6)

1. 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 Fully withdrawn for all control rods shall be 228 steps.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)

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 +5%.

3. The APL~ for Base Load operation is 85% of RATED THERMAL POWER.

2. g = 2.45 K(Z) is specified in Figure 3 of this attachment.

4. W(z) Curves for RAOC Operation are specified in Figures 4 through 6 of this attachment. These W(z) curves are sufficient to determine'he RAOC W(z) versus core height for Cycle 5 burnups through the end of full,power reactivity plus a power coastdown of up to 1245 MWD/MTU through the use of three point interpolation.

5. W(z) Curves for 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 5 burnups through the end of full power reactivity plus a power coastdown of up to 1245 MWD/MTU through the use of three point interpolation.

c. PF~= 0.3 for LOPAR fuel

d. PF>> = 0.35 for VA1FZAGE-5 fuel 2.7 Boron Concentration for Refuelin 0 erations (Specification 3/4.9 '.a) .

Through the end of Cycle 5, the boron concentration required to maintain K,~~

less than or equal to .95 is less restrictive than the'000 ppm boron requirement. Boron concentration must be maintained greater than or equal to 2000 ppm during refueling operations.
