NFS-0215 PSEG Nuclear LLC Page 4 of 12 Revision I SALEM UNIT I CYCLE 16 COLR March 2004 1.0 CORE OPERATING LIMITS REPORT This Core Operating Limits Report (COLR) for Salem Unit I Cycle 16 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:

3/4.1.1.4 Moderator Temperature Coefficient 3/4.1.3.5 Control Rod Insertion Limits 3/4.2.1 Axial Flux Difference 3/4.2.2 Heat Flux Hot Channel Factor - FQ(Z) 3/4.2.3 Nuclear Enthalpy Rise Hot Channel Factor - FNAH 3/4.9.1 Boron Concentration

NFS-0215 PSEG Nuclear LLC Page 5 of 12 Revision I SALEM UNIT I CYCLE 16 COLR March 2004 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.

2.1 Moderator Temperature Coefficient (Specification 3/4.1.1.4) 2.1.1 The Moderator Temperature Coefficient (MTC) limits are:

The BOL/ARO/HZP-MTC shall be less positive than 0 Ak/k/0 F.

The EOL/ARO/RTP-MTC shall be less negative than -4.5xl04 Ak/WkIF.

2.1.2 The MTC Surveillance limit is:

The 300 ppm/ARO/RTP-MTC should be less'negative than or equal to -3.8x104 Ak/k/0 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

NFS-0215 PSEG Nuclear LLC Page 6 of 12 Revision I SALEMT UNIT I CYCLE 16 COLR M'arch 2004 2.2 Control Rod Insertion Limits (Specification 3/4.1.3.5) 2.2.1 The control rod banks shall be limited in physical insertion as shown in Figure 1.

2.3 Axial Flux Difference (Specification 3/4.2.1)

[Constant Axial Offset Control (CAOC) Methodology]

2.3.1 The Axial Flux Difference (AFD) target band shall be the more restrictive of

(+6%, -9%) or the target band as defined in Reference 2.

2.3.2 The AFD Acceptable Operation Limits are provided in Figure 2.

2.4 Heat Flux Hot Channel Factor - FQ(Z) (Specification 3/4.2.2)

[F,,y Methodology]

FQ(Z) - FQP

• K(Z)forP>0.5 P

FQR P FQ(Z) S 05

• K(Z)forPO.5-where: P = THERMAL POWER RATED THERMAL POIPER 2.4.1 FQR = 2.40 2.4.2 K(Z) is provided in Figure 3.

2.4.3 F L = F RfP 1.0+PF.,/(.0 P)J where: F,,RTP = 1.75 for unrodded top core planes I through 21 1.80 for unrodded bottom core planes 22 through 61 2.13 for core plane containing Bank D control rods PF>,= 0.3

NFS-02 15 PSEG Nuclear LLC Page 7 of 12 Revision I SALEM UNIT 1 CYCLE 16 COLR March 2004 2.4.4 If the Power Distribution Monitoring System (PDMS) is used for core power distribution surveillance and is OPERABLE, as defined in Technical Specification 3.3.3.14, the uncertainty, UFQ, to be applied to the Heat Flux Hot Channel Factor FQ(z) shall be calculated by the following formula:

Q( 1. UQ U.

where:

UQ = Uncertainty for power peaking factor as defined in equation 5-19 of Reference 1.

U, = Engineering uncertainty factor.

= 1.03 Note: UFQ= PDMIS Surveillance Report Core Monitor Fxy Uncertainty in %.

2.4.5 If the INCORE movable detectors are used for core power distribution surveillance, the uncertainty, UFQ, to be applied to the Heat Flux Hot Channel Factor FQ(z) shall be calculated by the following formula:

UFO = Uq

• U.

where:

Uqu = Base FQ measurement uncertainty.

= 1.05 U, = Engineering uncertainty factor.

= 1.03

NFS-0215 PSEG Nuclear LLC Page 8 of 12 Revision I SALEM UNIT I CYCLE 16 COLR March 2004 2.5 Nuclear Enthalpy Rise Hot Channel Factor - FNAll (Specification 3/4.2.3)

F1WAH = FITP [1.0 + PFbj (1.0 - P,)

THERMAL POWER vhere: P = RATED THERMAL POWER 2.5.1 Fbl" TP(fRFA with IFM) 1.65 and. FA,,RTP(VH wvithout IFM,) = 1.57 2.5.2 PFAH = 0.3 2.5.3 If the Power Distribution Monitoring System (PDMS) is used for core power distribution surveillance and is OPERABLE, as defined in Technical Specification 3.3.3.14, the uncertainty, UFAH, to be applied to the Nuclear Enthalpy Rise Hot Channel Factor, FHN, shall be calculated by the following formula:

UFAH = 1.0 + UAH

%%!here:

UAH = Uncertainty for enthalpy rise as defined in equation 5-19 of Reference 1.

2.5.4 If the INCORE movable detectors are used for core power distribution surveillance, the uncertainty, UFAH, to be applied to the Nuclear Enthalpy Rise Hot Channel Factor F,&HN shall be calculated by the following formula:

UFAH = UFAHm where:

UFAHm =Base Ful measurement uncertainty.

= 1.04 2.6 Boron Concentration (Specification 3/4.9.1)

A Mode 6 boron concentration, maintained at or above 2164 ppm, in the Reactor Coolant System, the fuel storage pool, the refueling canal, and the refueling cavity ensures the most restrictive of the following reactivity conditions is met:

a) A K-effective (Kff) of 0.95 or less at All Rods In (ARI), Cold Zero Power (CZP) conditions with a 1% Ak/k uncertainty added.

b) A Kfr of 0.99 or less at All Rods Out (ARO), CZP conditions with a 1%

Ak/k uncertainty added.

c) A boron concentration of greater than or equal to 2000 ppm, which includes a 50 ppm conservative allowance for uncertainties.
