The cycle-specific pammeter 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 specitled in Technical Specification 6.9.1.11.
2.1 SHUTDOWN MARGIN - MODES 1. 2,3 and 4 (Specification 3/4.1.1.1) 2.1.1 The SHUTDOWN MARGIN shall be greater than or equal to 1.77 percent ak/k.
2.2 SHUTDOWN MARGIN - MODE 5 (Specification 3/4.1.1.2) 2.2.1 The SHUTDOWN MARGIN shall be greater than or equal to 1.0 percent ak/t.
2.3 Moderator Temperature Coefficient (Specification 3/4.1.1.3) 2.3.1 The Moderator Temperature Coefficient (MTC) limits are:
The BOUARO/HZP-MTC shall be less than or equal to + 0.7x10-4 aket/*F for power levels up to 70 percent RTP with a linear ramp to 0 aluk/*F at 100 percent RTP.
The EOUARO/RTP-MTC shall be less negative than - 4.3 x 10-4 Ak/k/'F.
2.3.2 The MTC Surveillance limit is:
The 300 ppm /ARO/RTP-MTC should be less negative than or equal to -3.65x10-4 Ak/b* F.
The 100 ppm /ARO/RTP-MTC should be less negative than - 4.0x10-4 Ak/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for RATED THERMAL POWER 2.4 Shutdown Rod Insertion Limit (Specification 3/4.1.3.5) 2.4.1 The shutdown rods shall be withdrawn to a position greater than or equal to 225 steps.
