2.0

- Operatine Limits ne 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 6.9.1.9.

2.1 Moderator Temocrature CoefTicient (Specification 3/4.1.1.4) r 2.1.1 ne Moderator Temperature Coefficient (MTC) limits are:

The MTC shall be less positive than the value given in Figure 1.

The ARO/RTP-MTC shall be less negative than -4.54E-4 Ak/k/ F at a vessel average s

temperature in the range from 553*F to 557 F.

where: ARO stands for All Rods Out RTP stands for Rated Thermal Power 3

2.1.2 The MTC Surveillance limit is:

The 300 ppm /ARO/RTP-MTC should be less negative than or equal to -3.84E-4 Ak/k/ F at a vessel average temperature in the range from 553*F to 557'F.
