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, 2.The Negative MTC Limit (ARO/RTP)shall be less negative than-49 pcm/'F.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THERMAL POWER RTP stands for RATED THERMAL POWER 2.2 Shutdown Rod Insertion Limit (Specification 3/4.1.3.5) 1.Fully withdrawn for all shutdown rods shall be 228 steps.2.3 Control Rod Insertion Limits (Specification 3/4.1.3.6) 1.The control rod banks shall be limited in physical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Fully withdrawn for all control rods shall be 228 steps.2.4 Axial Flux Difference (Specification 3/4.2.1)2.3.The acceptable operational space for Relaxed Axial Offset Control (RAOC)operation is specified in Figure 2 of this attachment.
The AXIAL FLUX DIFFERENCE (AFD)target band for Base Load operation is+5%.The APL~for Base Load operation is 85%of RATED THERMAL POWER.PLP-106 Rev.4 Page 68 of 80 P

4.5.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.
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.
