1 Desmption of Information: Attached is the Byron Unit 1 Cycle 10 Core Operating Limits Repat (COLR) in the ITS fornut and W(z) function.

Purpose ofInfarrnauon: The COLR incorporates the ITS farnat and W(Z) function. Byron Station is requested to perform a Plant Review of this docurnent. Upon completion of the Plant Review, Byron Stauon is to tramrrut the COLR partion to the Nuclear Regulatory Comnussion pursuant to l Technical Speedicauon 5.6.5. Please provide NFM (Erich Wurz) with a cxyy of Byron Station's corrpleted Plant Review and COLR submittal to the NRC.

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 are applicable for the entire cycle unless otherwise identified. These limits have been developed using the NRC-approved methodologies specified in Technical Specification 5.6.5.

I 2.1 Shutdown Marain (SDM)

The SDM limit for MODES 1,2,3, and 4 is: l 2.1.1 The SDM shall be greater than or equal to 1.3% AWk (LCOs 3.1.1,3.1.4,3.1.5,  ;

3.1.6, 3.1.8, 3.3.9; TRM TLCOs 3.1.b, 3.1.d. 3.1.f, 3,1.h, and 3.1.j).

The SDM limits for MODE 5 are:

2.1.2.1 SDM shall be greater than or equal to 1.0% AWk (LCO 3.1.1) 2.1.2.2 SDM shall be greater than or equal to 1.3% Ak/k (LCO 3.3.9; TRM TLCO 3.1.1 and 3.1.j) 2.2 Moderator Temoerature Coefficient (LCO 3.1.3)

The Moderator Temperature Coefficient (MTC) limits are:

2.2.1 4 The BOUARO/HZP-MTC shall be less positive than +3.8 x 10 Ak/k/'F.

2.2.2 The EOUARO/HFP-MTC shall be less negative than -4.1 x 10" Ak/k/*F.

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