2.0 OPERATING LIMITS l
The cycle-specific parameter limits for the specifications listed in section 1.0 i
are presented in the following subsections. These limits have been developed i
using the NRC-approved methodologies specified in Technical Specification 6.B.1.6 2.1 SHUTDOWN MARGIN - MODES 1 AND 2 (Specification 3/4.1.1.1) 2.1.1 The SHUTDOWN MARGIN shall be greater than or equal to l.3 percent M /k.
)
2.2 SHUTDOWN MARGIN - MODES 3. 4 AND 5 (Specification 3/4.1.1.2)
I 2.2.1 The SHUTDOWN MARGIN shall be greater than or equal to the limits shown in figures I and 2.
2.3 Moderator Temperature Coefficient (Specification 3/4.1.1.3) 2.3.1 The Moderatar Temperature Coefficient (MTC) limits are:
The BOL/AR0/HZP - MTC shall be less positive than 40.7 x 10-' &/k/*F for power levels up to 70 percent RTP with a linear ramp to 1
0 m/k/*F at 100 percent RTP, The E0L/AR0/RTP-MTC shall be less negative than
-5.45 x 10" M/k/*F.*
s 2.3.2 The MIC Surveillance limit is:
The 300 ppm /AR0/RTP-MTC should be less negative than or equal to -4.70 x 10-* M/k/*F.*
]
where:
BOL stands for Beginning of Cycle Life i
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for RATED THERMAL POWER 2.4 Shutdown Rod Insertion limit (Specification 3/4.1.3.5) 2.4.1 The shutdown rods shall be withdrawn to a position greater than or equal to 225 steps.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 '
trol rod banks shall be limited in physical insertion as shown in figure 3.
- Based on full-power T-average in the range of 583.4 to 585.4*F, inclusive.
