1.0 CORE OPERATII\G LIMITS REPORT This Core Operating Limits Repgrt (COLR) for Watts Bar Unit I Cycle l6 has been prepared in accordance with the requirements of the Technical Specifications (TS) 5.9.5.

The Technical Specifications affected by this report are listed below:

3.1.4 Moderator Temperature Coefficient (MTC) 3.1.5 Rod Group Alignment Limits 3.1.6 Shutdown Bank lnsertion Limits 3.1.7 Control Bank lnsertion Limits 3.2.1 Heat Flux Hot Channel Factor (F,t(Z))

3.2.2 Nuclear Enthalpy Rise Hot Channel Factor (F^r*)

3.2.3 Axial Flux Difference (AFD) 3.9. I Boron Concentration 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 the Technical Specifications Section 5.9.5.

The following abbreviations are used in this section:

BOL Beginning of Cycle Life ARO All Rods Out HZP Hot Zero Thermal Power EOL End of Cycle Life RTP Rated Thermal Power 2.1 MODERATOR TEMPERATURE COEFFTCTENT - MTC (LCO 3.1.4) 2.1.1 The MTC limits are:

The ARO/HZP - MTC shall be less positive than or equal to 0 Ak/ld'F (upper limit).

With the measured BOL/ARO/HZP - MTC more positive than -3.277 x 10 5 AVld"F (as-measured MTC limit), establish control rod withdrawal limits to ensure the MTC remains less positive than or equal to 0 Ak/ld'F (upper limit) for all times in core life.

The EOLIARO/RTP - MTC shall be less negative than or equal to

-4.5 x l0-aAk/V"F (lower limit).

2.1.2 The 300 ppm surveillance limit is:

The measured 300 ppm IARO/RTP-MTC should be less negative than or equal to -3.75 x l0-a Ak/k/"F.

2.1.3 The 60 ppm surveillance limit is:

The measured 60 ppm /ARO/RTP-MTC should be less negative than or equal to -4.28 x 104 Ak/k/"F.

2.2.2 For TS 3.1.6, SDM shall be > 1.6% Ak/k in MODE I and MODE 2.

2.2.3 For TS 3.1.7, SDM shall be > I .6% Ak/k in MODE I and MODE 2 with keff> 1.0.

2.3 SHUTDOWN BAr\K TNSERTION LIMTTS (LCO 3.r.6) 2.3.1 The shutdown banks shall be withdrawn to a position greater than or equal to 225 steps withdrawn.

2.4 CONTROL BANK TNSERTTON LIMTTS (LCO 3.1.7) 2.4.1 The control banks are fully withdrawn or shall be limited in physical insertion as shown in Figure l.

2.4.2Each confrol bank shall be considered fully withdrawn from the core at greater than or equal to 225 steps.

2.4.3 T\e confrol banks shall be operated in sequence by withdrawal of Bank A, Bank B, Bank C, and Bank D. The control banks shall be sequenced in reverse order upon insertion.

2.4.4 Each control bank not fully withdrawn from the core shall be operated with the following overlap as a function of park position.
