NFS-0174 Revision 0 April 7, 1999 Salem Unit 2 Cycle 11 COLR 1.0 CORE OPERATING LIMITS REPQRT This Core Operating Limits Report (COLR) for Salem Unit 2 Cycle 11 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 I emperature Coefficient 3/4.1.3.5 Control Rod Insertion Limits 3/4.2. l Axial Flux Difference 3/4.2.2 Heat Flux Hot Channel Factor* F0(Z) 3/4.2.3 Nuclear Enthalpy Rise Hot Channel Factor - FN ~

NFS-0174 Revision 0 April 7, 1999 Salem Unit 2 Cycle 11 COLR 2.0 OPERATING LIMITS The cycle-specific parameter limits for the specifications listed in Section 1.0 are presenced 1n rhe following subsections. These limits have been developed using the NRC-approved mechodologies specified in Technical Specification 6.9.1.9.

2.1 Moderator Temperature Coefficient (Specification 3/4. l. l .3) 2.1. l The Moderator Temperature Coefficient (MTC) limits are:

The BOL/AROIHZP-MTC shall be less positive than 0 ~°F.

The EOL/ARO/RTP-MTC shall be less negative than-4.5x10"" ~°F.

2.1.2 The MTC Surveillance limit is:

The 300 ppm/ARO/RTP-MTC should be less negative than or equal to -3.8xl0 4 ~k/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 S of 10

NFS-0174 Revision 0 April 7, 1999 Salem Unit 2 Cycle 11 COLR 2.2 Control Rod Insertion Limits (Specification 314.1.3.5) 2.2.1 The control rod banks shall be limited in physical insenion 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 is +6%, -9%.

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