Harris Unit 1 Cycle 7 Core Operating Limits Report - Rev. 1 September 5, 1995 NFM&SA File: 2495-0056 9510190003 951010 PDR ADOCK 05000400 P PDR

Sheet 1 of 11 Harris Unit 1 Cycle 7 Core Operating Limits Report - Rev. 1 1.0 R T I This Core Operating Limits Report (COLR) for Shearon Harris Unit 1 Cycle 7 has been prepared in accordance with the requirements of Technical Specification 6.9.1.6.

The Technical Specifications affected by this report are listed below:

3/4.1.1.2 SHUTDOWN MARGIN - Modes 3, 4, and 5 3/4.1.1.3 Moderator Temperature Coefficient 3/4.1.3.5 Shutdown Rod Insertion Limit 3/4.1.3.6 Control Rod Insertion Limits 3/4.2.1 Axial Flux Difference 3/4.2.2 Heat Flux Hot Channel Factor - F<(Z) 3/4.2.3 Nuclear Enthalpy Rise Hot Channel Factor - F>>,

3/4.9.1.a Boron Concentration During Refueling Operations

Sheet 2 of 11 Harris Unit 1 Cycle 7 Core Operating Limits Report - Rev. 1 2.0 I T 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 NRC-approved methodologies specified in Technical Specification 6.9.1.6 and given in Section 3.0.

2.1 D W R I (Specification 3/4.1.1.2)

The SHUTDOWN MARGIN versus RCS boron concentration - Modes 3, 4, and 5 is specified in Figure 1.

2.2 r T e i (Specification 3/4.1.1.3)

1. The Moderator Temperature Coefficient (MTC) limits are:

The Positive MTC Limit (ARO/HZP) shall be less positive than +5.0 pcm/'F for power levels up to 70% RTP with a linear ramp to 0 pcm/'F at 100% RTP.

The Negative MTC Limit (ARO/RTP) shall be less negative than -45 pcm/'F.

2. The MTC Surveillance limit is:

The 300 ppm/ARO/RTP-MTC should be less negative than or equal to -37.0 pcm/'F.

where: ARO stands for All Rods Out HZP stands for Hot Zero THERMALPOWER RTP stands for RATED THERMAL POWER 2.3 (Specification 3/4.1.3.5)

Fully withdrawn for all shutdown rods shall be 231 steps.

2.4 (Specification 3/4.1.3.6)

The control rod banks shall be limited in physical insertion as specified in Figure 2. Fully withdrawn for all control rods shall be 231 steps.

2.5 (Specification 3/4.2.1)

The AXIALFLUX DIFFERENCE (AFD) target band is specified in Figure 3.

a. F<"~ = 2.45 for LOPAR and VANTAGE 5 fuel
b. F "r' 2.52 for SPC fuel
c. K(Z) is specified in Figure 4.

V(Z) Curve for PDC-3 Operation is specified in Figure 5. The V(Z) curve is sufficient to determine the PDC-3 V(Z) versus core height for Cycle 7 burnups through the end of full power reactivity plus a coastdown for a maximum cycle energy of 519 EFPDs.

d. PF>>, = 0.3 for LOPAR fuel
e. PF>>, = 0.35 for VANTAGE5 and SPC fuel 2.8 (Specification 3/4.9.1.a)

Through the end of Cycle 7, the boron concentration required to maintain K, less than or equal to .95 is equal to 2304 ppm. Boron concentration must be maintained greater than or equal to 2304 ppm during refueling operations.
