'Ihe cycle-specific parameter limits for the specifications listed in Section 1.0 are presented in the subsections which follow.These limits have been developed using the NRC approved methodologies speciGed in Technical Specification 6.9.1.11.

2.1 hinderator Temperature Coe@iit01(SpeciGcation 3.1.1.3) 2.1.1 *Ihe hinderator Temperature Coefficient (htTC) limits are:

1he llOlJARO h1TC shell be less positive than the limits shown in Figure 1.

The EOl/APO/RTP htTC shall be less negative than .5x10d Ak/k/* F.

2.1.2 1he h1TC Surveillance limit is:

The 300 ppm /ARO/RTP htTC should be less negative than or equal to .4.1x10 d Ak/k/* F.

where: BOL stands for Beginning of Cycle Life ARO stands for All Rods Out RTP stands for RATED TilERMAL POWER EOL stands for End of Cycle Life Virgil C. Summer 2 Core Operating Limits Report Cycle 7. Revision 0

This information is sufficient to determine W(z) versus core height in th range of 0 MWD /MTU to EOL burnup. Three point interpolation of the data in Figures 7 through 9 is sufficient to determine RAOC W(z) versus core height between a Cycle burnop of 0 to 4000 MWD /MTU. For Cycle burnups between 4000 MWD /MTU and EOL burnup, W(z) versus core height may be obtained through three point interpolation of the data in Figures 8 through 10.

2.5.4 Elevation dependent W(z)BL values for base load operation between 85 and 100% of rated thermal power with the item 2.4.2 specified target band about a measured target value at 150, 8000, and 16000 MWD /MTU are shown in Figures 11 through 13, respectively. This information is sufficient to determine W(z)3t versus core height for burnups in the range of 0 MWD /MTU to EOL burnup through the use of three point interpolation.
