- NOVEMBER 1997 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 6.9.1.9.

2.1 Moderator Tem erature Coefficient (Specification 3/4.1.1.4) 2.1.1 The 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 P.54E-4 dk/k/'F at a vessel average temperature in the range from 553'F to 557'F.-

where: ARO stands forAllRods Out RTP stands for Rated Thermal Power 2.1.2 The MTC Surveillance limitis:

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

2.3 Shutdown Rod Insertion Limit(Specification 3/4.1.3.4) 2.3.1 The shutdown rods shall be withdrawn to 225 steps.

2.4 Control Rod Insertion Limits (Specifications 3/4.1.3.5 and 3/4.1.3.1) 2.4.1 The control rod banks shall be limited in physical insertion as shown in Figure 2.

2.4.2 Successive Control Banks shall overlap by 97 steps.

The sequence for Control Bank withdrawal shall be Control Bank A, Control Bank B, Control Bank C, and Control Bank D.

2,5 AxialFlux Difference (Specification 3/4.2.1) 2.5.1 The Allowable Operation Limits are provided in Figure 3.

2.5.2 The ALGALFLUXDIFFERENCE (AFD) target band during base load operations is M%.

(not applicable for this cycle).

2.5.3 The AFD target band is+&% for a cycle average accumulated burnup > 0.0 MWD/MTU.
