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 6.8.1.6.
2.1 SHUTDOWN MARGIN - MODES 1 AND 2 (Specification 3/4.1.1.1) f-2.1.1 The SHUTDOWN MARGIN shall be greater than or equal to 1.3% M/k.
I j
2.2 SHUTDOWN MARGIN - MODES 3. 4 AND 5 (Specification 3/4.1.1.2) l j
2.2.1 The SHUTDOWN MARGIN shall be greater than or equal to the limits shown in Figures 1 and 2.
l 2.3 Moderator Temnerature Coefficient (Specification 3/4.1.1.3) l 2.3.1 The Moderator Temperature Coefficient (MTC) limits are:
l The BOL/ARO/HZP - MTC shall be less positive than +0.7 x 10
)
&/k/*F for power levels up to 70% RTP with a linear ramp to 0 M/k/*F at 100% RTP.
The EOL/AR0/RTP-MTC shall be less negative than -5.5 x 10
&/k/'F 2.3.2 ' The MTC Surveillance limit is:
The 300 pps/AR0/RTP-MTC should be less negative than or equal to
-4.75 x 10' &/k/*F.*
where:
BOL stands for Beginning of Cycle Life ARO stands for All Rods Out HZP stands for Hot Zero THERMAL POWER EOL stands for End of Cycle Life RTP stands for RATED THERMAL POWER 2.4 Shutdown Rod Insertion Limit (Specification 3/4.1.3.5) 2.4.1 The shutdown rods shall be withdrawn to a position greater than or equal to 225 steps.
2.5 Control Rod Insertion Limits (Specification 3/4.1.3.6) 2.5.1 The control rod banks shall be limited in physical insertion as shown in Figure 3.
O Applicable for full-power T-average of 586.4*F.

C 1.
The Penalty Factor, to be applied to F (Z) in accordance with surveillance requirement 4.2.2.2.f, is the maximum factor by which F (Z) is expected to C
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 the burnup at which the CF (Z) was determined.
2.
Linear interpolation is adequate for intermediate cycle burnups.
3.
For All cycle burnups outside the range of the table, a penalty factor of 1.0200 shall be used.
