4 COLR for VEGP UNIT 2 CYCLE 3 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) 2.1.1 The SHUTDOWN MARGIN shall be greater than or equal to 1.3% & /k.
- 2.2 SHUTDOWN MARGIN - MODES 3. 4 AND 5 (Specification 3/4.1.1.2) 2.2.1 The SHUTDOWN MARGIN shall be greater than or equal to the limits shown in figures 1 and 2.
2.3 Moderator Temperature Coefficient (Specification 3/4.1.1.3) 2.3.1 The-Moderator Temperature Coefficient (MTC) lin11ts are:
The BOL/AR0/H7P - MTC shall be less positive than +0.7 x 10
M/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 thar -5.6 x 10
M/k/*F.*
2.3.2 The MTC Surveillance limit is: ,
The 300 ppm /AR0/RTP-MTC should be less negative than or equal to
-4.85 x 10 &/k/*F.*
where: BOL stands for Beginning of Cycle Life AR0 stands for All Rods Out HZP stands for Hot Zero THERMAL POWER E0L stands for End of Cycle Life RTP stands for RATED THERMAL POWER
- 2,4 Shutdown ~ Rod Insertion Limit.(Specification 3/4.1.3.5) l- 2.4.1- The shutdown rods shall be withdrawn to a position greater than or i' equal to 225 steps.
2 '. 5 -Control Rod Insertion limill (Specification 3/4.1.3.6) l 2.5.1 The control rod banks shall be limited in physical insertion as shown in Figure 3.
Based on full-power T-average of 586.4"F.
