• 1.0 OPERATING LIMITS REPORT This Operating Limits Report (OLR) for Braidwood Station Unit 1 Cycle 8 has been prepared in accordance with the requirements of Technical Specification 6.9.1.9.

The Technical Specifications affected by this report are listed below:

3/4.1.1.3 Moderator Temperature Coefficient 3/4.1.3.5 Shutdown Rod Insertion Limit 3/4.1.3.6 Control Rod Insertion Limits 3/4.2.1 Axial Flux Difference 3/4.2.2 Heat Flux Ho.t Channel Factor 3/4.2.3 Nuclear Enthalpy Rise Hot Channel Factor 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 6.9.1.9.

,q 2.1 Moderator Temperature Coefficient (Specification 3/4.1.1.3) 2.1.1 The Moderator Temperature Coefficient (MTC) limits are:

a. The BOUARO/HZP-MTC shall be less positive than +3.8 x 104 Ak/k/*F.

b. The EOUARO/RTP-MTC shall be less negative than -4.1 x 10d Ak/k/*F.

2.1.2 The EOUARO/RTP-MTC Surveillance limit is:

The 300 ppm /ARO/RTP-MTC should be less negative than or equal to -3.2 x 10d 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
