- 2.0 OPERATING LIMITS 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 Temperature Coefficient (Specification 3/4.1.1.4) 2.1.1 The Moderator Temperature Coefficient (MTC) limits are:
The BOL/ARO/HZP-MTC shall be less positive than 0 &/k/°F.
The EOL/ARO/RTP-MTC shall be less negative than -4.4 x 104 &/k/°F.
2.1.2 The MTC Surveillance limit is:
The 300 pprn/ARO/RTP-MTC should be less negative than or equal to -3.7xl0 4 &/k/°F.

- Attachment 1 2.2 Contr~l Rod Insertion Limits (Specification 3/4.1.3.5) 2.2.1 The control rod banks shall be limited in physical insertion as shown in Figure 1.
2.3 Axial Flux Difference (Specification 3/4.2.1)
[Constant Axial Offset Control (CAOC) Methodology]
2.3.1 The Axial Flux Difference (AFD) target band is +6%, -9%.
2.3.2 The AFD Acceptable Operation Limits are provided in Figure 2.
2.4 Heat Flux Hot Channel Factor - FQ(Z) (Specification 3/4.2.2)
[Fxy Methodology]
- K(Z) for P > 0.5 FRTP Q
- K(Z) for P::; 0.5 0.5 THERMAL POWER where: p RATED THERMAL POWER 2.4.1 FtTP = 2. 40 2.4.2 K(Z) is provided in Figure 3.

2.4.3 where
F~TP =1. 77 for the unrodded core planes 2.13 for the core plane containing Bank D control rods 2.5 Nuclear Enthalpy Rise Hot Channel Factor - fNt-H (Specification 3/4.2.3)
F~ = FftP [1.0 + PFlili (1.0 - P)]
Operation with FNt.H values equal to or less than those given by the above equation are acceptable.
THERMAL POWER where: P RATED THERMAL POWER 2.5.1 FftP = 1.65 2.5.2 PFlili = 0.3 Page 4 of 7
