i 2.0 2PERATING 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 i
specified in Technical Specifications 6.9.1.6.
2.1 Moderator Temperature Coefficient (Specification 3/4.1.1.3) 2.1.1 The Moderator Temperature Coefficient (MTC) limits are:
The BOL/ARO/HZP-MTC shall be less positive than i
+5 pcm/ F.
The EOL/ARO/RTP-MTC shall be'less negative than l
-40 pcm/ F.
l 1
2.1.2 The MTC surveillance limit is:
i The 300 ppm /ARO/RTP-MTC should be less negative j
i than or equal to -31 pcm/ F.
i l
where:
BOL stands for Beginning of Cycle Life ARO stands for All Rods Out i
HZP stands for Hot Zero THERMAL POWER i
EOL stands for End of Cycle Life RTP stands for RATED THERMAL POWER i

l 2.2 Shutdown Rod Insertion Limit (Specification 3/4.1.3.5) 2.2.1 The shutdown rods shall be fully withdrawn.
i Fully withdrawn shall be the condition where 3
shutdown rods are at a position within the interval of 222 and 231 steps withdrawn, inclusive.
2.3.
Control Rod Insertion Limits (Specification 3/4.1.3.6) 2.3.1 The control banks shall be limited in physical insertion as shown in Figure 1.
k 2.4 Axial Flux Difference (Specification'3/4.2.1) 2.4.1 The AXIAL FLUX. DIFFERENCE (AFD) target band is
+5%, -5%,
for core average accumulated burnup 5 5000 MWD /MTU.
2.4.2 The AFD target band is +3%, -9%,
for' core average accumulated burnup > 5000 MWD /MTU.
