h COLR for-VEGP UNIT 1 CYCLE 5 2.0 QPERATING 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 percent M /k.

2.2 SHUTDOWN MARGIN - MODES 3. 4 AND 5 (Specification 3/4.1.1.2) j 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) limits are
[

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

for power levels up to 70 percent RTP with a linear ramp to 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.* .

o 2.3.2 The MTC 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 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2.4.1 The shutdown rods shall be withdrawn to a position greater than or equal to 225 steps.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.

  • Based on full-power 1-average in the range of 583.4 to 586.4*F, inclusive.
