1 CORE OPERATING LIMITS REPORT D4. FARLEY UNIT 1 CYCLE 15 2.0 Operatine Limits i

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 6.9.1.11.

2.1 SHUTDOWN MARGIN - MODES 1. 2. 3 and 4 (Specification 3/4.1.1.1) 2.1.1 The SHUTDOWN MARGIN shall be greater than or equal to 1.77 percent Ak/k.

J 2.2 SHUTDOWN M ARGIN - MODE 5 (Specification 3/4.1.1.2) 2.2.1 The SHUTDOWN MARGIN shall be greater than or equal to 1.0 percent Ak/k.

2.3 Moderator Temnerature Coefficient (Specification 3/4.1.1.3) 2.3.1 The Moderator Temperature Coefficient (MTC) limits are:

The BOL/ARO/HZP-MTC shall be less positive than + 0.7x10" Ak/k/ F for power t

levels up to 70 percent RTP with a linear ramp to 0 Ak/k/ F at 100 percent RTP.

The EOUARO/RTP-MTC shall be less negative than - 4.3 x 10" Ak/k/ F.

2.3.2 The MTC Surveillance limit is:

The 300 ppm /ARO/RTP-MTC should be less negative than or equal to

- 3.65x10" Ak/k/ F.

The 100 ppm /ARO/RTP-MTC should be less negative than or equal to

- 4.0x10" Ak/k/ F.

where: BOL stands for Beginning of Cycle Life t

ARO stands for All Rods Out l

HZP stands for Hot Zero THERMAL POWER l

EOL stands for End of Cycle Life i

RTP stands for Rated THERMAL POWER Page 2 of 12 r

The Penalty Factor, to be applied to Fh(Z) in accordance with surveillance requirement l 1.

4.2.2.2.f, is the maximum factor by which Fh(Z) is expected to increase over a 39 EFPD interval (surveillance interval of 31 EFPD plus the maximum allowable extension not to exceed 25% of the surveillance interval per Technical Specification 4.0.2) starting from 1

- the burnup at which the Fh(Z) was determined.

2.

Linear interpolation is adequate for intermediate cycle burnup.

l 3.

For ajiburnups outside the range of the table, a penalty factor of 1.0200 shall be used.
