h V. C. SUMMER CYCLE 11 APRIL 1998 SCE&Q 1.0 Core Operating Limits Report This Core Operating Limits Report (COLR) for V. C. Summer Station Cycle 11 has been prepared in accordance with the requirements of Technical Specification 6.9.1.11. The COLR was revised to remove the 7,000 MWD /MTU core average burnup limit imposed for gap reopening. j The Technical Specifications affected by this report are listed below:

3.1.1.3 MODERATOR TEMPERATURE COEFFICIENT 3.1.3.5 SIIUTDOWN ROD INSERTION LIMITS 3.1.3.6 CONTROL ROD INSERTION LIMITS 3.2.1 AXIAL FLUX DIFFERENCE 3.2.2 IIEAT FLUX liOT CliANNEL FACTOR 3.2.3 RCS FLOW RATE and NUCLEAR ENTliALPY RISE liOT CliANNEL FACTOR l

1 Revision I

V. C. SUMMER CYCLE 11 NOVEMBER 1997 2.0 Operating Limits The cycle-specific parameter limits for the specifications listed in Section 1.0 are presented in the 1 subsections which follow. These limits have been developed using the NRC-approved methodologies

, specified in Technical Specification 6.9.1.11.

i i l 2.1 MODERATOR TEMPERATURE COEFFICIENT (Specification 3.1.1.3):

l

1

2.1.1 The Moderator Temperature Coefficient (MTC) limits are

l The BOUARO-MTC shall be less positive than the limits shown in Figure 1.

4 l The EOUARO/RTP-MTC shall be less negative than -5x10 Ak/k/ F.

l 2.1.2 The MTC Surveillance limit is:

4 The 300 ppm /ARO/RTP-MTC should be less negative than or equal to -4.1x10 Ak/k/ F.

l where: BOL stands for Beginning-of-Cycle-Life ARO stands for All-Rods-Out l RTP stands for RATED THERMAL POWER l EOL stands for End-of-Cycle-Life l 2.2 SHUTDOWN ADD INSERTION LIMITS (Specification 3.1.3.5):

l The shutdown rods shall be withdrawn to at least 228 steps.

2.3 CONTROL ROD INSERTION LIMITS (Specification 3.1.3.6):

The Control Bank Insertion Limits are specified by Figure 2.

2.4 AXIAL FLUX DIFFERENCE (Specification 3.2.1):

2.4.1 The Axial Flux Difference (AFD) Limits for RAOC operation for Cycle 11 are shown in Figure 3. l 2.4.2 The Axial Flux Difference (AFD) target band during base load operations for Cycle 11 is:

BOL - EOL (0 - 22,480 MWD /MTU): 2 5% about a measured target value.

k 2.4.3 The minimum allowable power level for base load operation, APL ,is 85% of RATED THERMAL POWER.
