CORE OPERATING LIMITS REPORT (COLR) for BRAIDWOOD UNIT 2 CYC1.E 7 2.0 OPERATING LIMITS The cycle-specific parameter hmits for the specifications listed in Section 1.0 are preser..;d in the following subsecbons. These limits are applicable for the entire cycle unless otherwise identified.

These limits have bee 19eveloped using the NRC approved methodologies specified in Technical Specification 5.6.5.

2.1 Shutdown Mamin (SDM) ,

The SDM limit for MODES 1,2,3, and 4 is:  ;

2.1.1 The SDM shall be greater than or equal to 1.3% Alvk (LCOs 3.1.1,3.1.4,3.1.5, 3.1.6. 3.1.8 and 3.3.9; TRM TLCOs 3.1.b,3.1.d. 3.1.f,3.1.h and 3.1.j). l The SDM Emits for MODE 5 are: I

. I 2.1.2.1 SDM shall to greater than or equal to 1.0% Ak/k (LCO3.1.1) l 2.1.2.2 SDM shaN be greater than or equal to 1.3% Alvk (LCO 3.3.9; TRM TLCO 3.1.1 and 3.1.j) 2.2 Moderator Temperature Coomcer.nl (LCO 3.1.3)

The Moderator Temperature Cosmcient (MTC) limits are:

2.2.1 The BOUARO/HZP MTC shall be less positive than +3.5 x 10-' Alviv'F.

2.2.2 The EOUARO/HFP MTC shall be less negative than -4.1 x 10d ak/lv'F.

2.2.3 The EOUARO/HFP-MTC Surveillance limit at 300 ppm shan be less negative than or equal to-3.2 x 10dAlvk/*F.

where: 80L 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 HFP stands for Hot FullThermal Power
