COLR for VEGP UNIT 2 CYCLE 3 2.0 OPERATING LIMITS j The cycle-specific parameter limits for the specifications listed in Section 1.0 l are presented in the following subsections. These limits have been developed l using the NRC-approved methodologies specified in Technical Specification 6.8.1.6. l r

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% ok/k. l 2.2 SHUT 00WN MARGIN - MODES 3. 4 AND 5 (Specification 3/4.1.1.2) l 2.2.1 The SHUTDOWN MARGIN shall be greater than or equal to the limits shown in Figures 1 and 2.

2.3 Moderator Temoerature Coefficient (Specification 3/4.1.1.3) -j 2.3.1 The Moderator Temperature Coefficient (MTC) limits are: '

The BOL/AR0/HZP - MTC shall be less positive than +0.7 x 10-' '

Ak/k/*F for power levels up to 70% RTP with a linear ramp to 0 ak/k/*F at 100% RTP.

The E0L/AR0/RTP-MTC shall be less negative than -5.5 x 10  !

Ak/k/*F.

  • 2.3.2 The MTC Surveillance limit is:

P The 300 ppm /AR0/RTP-MTC should be less negative than or equal to  !

-4.75 x 10~' ak/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 i 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for RATED THERMAL POWER 2.4 Shutdown Rod Insertion Limit (Specification 3/4.1.3.5) 2.4.1 The shutdown rods shall be withdrawn to a position greater than or '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. ,
