In the Matter of
)
Docket No.50-390 Tennessee Valley Authority WATTS BAR NUCLEAR PLANT (WBN) UNIT 1-CORE OPERATING LIMITS REPORT FOR CYCLE 6, REVISIONS 3 AND 4 The purpose of this letter is to provide the Cycle 6 Core Operating Limits Report (COLR) in accordance with WBN Technical Specification 59.5.d.
Enclosed are Revisions 3 and 4 of the COLR.
Revision 3, which was effective on September 29, 2003, was limited to Modes 6 and 5 of the Cycle 5 Refueling Outage in order to permit core load and reactor assembly to proceed in advance of NRC's approval of the License Amendment Requests for Robust Fuel Assemblies and Boron Concentration Reductions in the refueling water storage tank and the cold leg accumulators.
Revision 4 of the COLR was effective October 13, 2003, and removed the restrictions identified in Revision 3 following NRC's approval of the above License Amendment Requests in Amendments 46 and 48, respectively.

COLR for Watts Bar Unit 1, Cycle 6 - TPC Redesign 1.0 CORE OPERATING LIMITS REPORT This Core Operating Limits Report (COLR) for Watts Bar Unit 1 Cycle 6 has been prepared in accordance with the requirements of the Technical Specifications 5.9.5.
The Technical Specifications affected by this report are listed below:
3.1.4 Moderator Temp:erature Coefficient (MTC) 3.1.6 Shutdown Bank Insertion Limits 3.1.7 Control Bank Insertion Limits 3.2.1 Heat Flux Hot Channel Factor (FQ(Z))
3.2.2 Nuclear Enthalpy Rise Hot.Channel Factor (FtH")
3.2.3 Axial Flux Difference (AFD) 3.5.1 Accumulators 3.5.4 Refueling Water Storage Tank (RWST) 3.9.1 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:

COLR for Watts Bar Unit 1, Cycle 6 - TPC Redesign 2.1 MODERATOR TEMPERATURE COEFFICIENT - MTC (LCO 3.1.4) 2.1.1 The MTC limits are:
The BOLUAROIHZP - MTC shall be less positive than or equal to 0 AkJk/0F (upper limit). With the measured BOLJARO/HZP - MTC more positive than
-0.70 x 10` Ak/k/0F (as-measured MTC limit), establish control rod withdrawal limits to ensure the MTC remains less positive than or equal to 0 Ak/k/'F (upper limit) for all times in core life.
The EOLIARO/RTP - MTC shall be less negative than or equal to
-4.5 x 0 Ak/k/0F (lower limit).
2.1.2 The 300 ppm surveillance limit is:
The measured 300 ppm ARO/RTP-MTC should be less negative than or equal to
-3.75 x 10' AWk/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 SHUTDOWN BANK INSERTION LIMITS (LCO 3.1.6) 2.2.1 The shutdown banks shall be withdrawn to a position greater than or equal to 225 steps withdrawn.
2.3 CONTROL BANK INSERTION LIMITS (LCO 3.1.7) 2.3.1 The control banks shall be limited in physical insertion as shown in Figure 1.

2.4.3 FC(Z) = FQm(Z)
- 1.0815 where: FQM(Z) is the measured value of FQ(Z) obtained from incore flux map results and 1.0815 is a factor that accounts for fuel manufacturing tolerances and flux map measurement uncertainty.
2.4.4 FQW(Z) = FQC(Z)
- W(Z) where:
W(Z) values are provided in Figures 4 through 7. The figures provide sufficient information to determine W(Z) versus core height for all cycle burnups.
2.4.5 FQW(Z)
Penalty Factor The FQW(Z) penalty factor is provided In Table A. 1.

COLR for Watts Bar Unit 1, Cycle 6 - TPC Design 1.0 CORE OPERATING LIMITS REPORT This Core Operating Limits Report (COLR) for Watts Bar Unit 1 Cycle 6 has been prepared in accordance with the requirements of the Technical Specifications 5.9.5.
The Technical Specifications affected by this report are listed below:
3.1.4 Moderator Temperature Coefficient (MTC) 3.1.6 Shutdown Bank Insertion Limits 3.1.7 Control Bank Insertion Limits 3.2.1 Heat Flux Hot Channel Factor (F,(Z))
3.2.2 Nuclear Enthalpy Rise Hot Channel Factor (FH')
3.2.3 Axial Flux Difference (AFD) 3.5.1 Accumulators 3.5.4 Refueling Water Storage Tank (RWST) 3.9.1 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:

COLR for Watts Bar Unit, Cycle 6 - TPC Design 2.1 MODERATOR TEMPERATURE COEFFICIENT - MTC (LCO 3.1.4) 2.1.1 The MTC limits are:
The BOIJARO/HZP - MTC shall be less positive than or equal to 0 k/°F (upper limit). With the measured BOLAROIHZP - MATC more positive than
-0.70 x 10 ' ALdcld0F (as-measured MTC limit), establish control rod withdrawal limits to ensure the MTC remains less positive than or equal to 0
&/kf°F (upper limit) for all times in core life.
The EOIJARO/RTP - MTC shall be less negative than or equal to
-4.5 x 104 Ak/k1PF (lower limit).
2.1.2 The 300 ppm surveillance limit is The measured 300 ppm AROJRTP-MTC should be less negative than or equal to
-3.75 x 10' Ak/

2.1.3 The 60 ppm surveillance limit is:
The measured 60 ppm /AROIRTP-MTC should be less negative than or equal to
-4.28 x 104 Ak/kI0F.
2.2 SHUTDOWN BANK INSERTION LIMITS (LCO 3.1.6) 2.2.1 The shutdown banks shall be withdrawn to a position greater than or equal to 225 steps withdrawn.
2.3 CONTROL BANK INSERTION LIMITS (LCO 3.1.7) 2.3.1 The control banks shall be limited in physical insertion as shown in Figure 1.
2.3.2 Table 1 shows the control rod overlap positions.

W(Z) values are provided in Figures 4 through 7.
The figures provide sufficient information to determine W(Z) versus core height for all cycle burnups.

Notes:
- 1. The Penalty Factor, which is applied to FQW(Z) for compliance with Surveillance Requirement 3.2.1.2.a, is the maximum factor by which Fw(Z) is expected to increase per 31 Effective Full Power Days (EFPD) starting from the burnup at which the Fw(Z) was determined.
- 2. Linear interpolation is adequate for intermediate cycle burnups.
- 3. For all cycle burnups outside the range of the table, a penalty factor of 1.020 shall be used for compliance with Surveillance Requirement 3.2.1.2.a.
