HNEI-0400-0016 Revision 1 Page 2 Harris Unit 1 Cycle 23 Core Operating Limits Report Implementation Instructions for Revision 1 Revision Description and AR Tracking Revision 1 of the Harris Unit 1 Cycle 23 (H1C23) Core Operating Limits Report (COLR) contain limits specific to the redesigned reload core based on the information obtained from HNP-F/NFSA-0351, Revision 1. A H1C23 core redesign was required due to elevated resistance observed during in-core RCCA drag testing for a single fuel assembly in core location F-12 as documented in AR 02300932.

The core was redesigned such that this fuel assembly and its octant-symmetric partners are exchanged with a neutronically similar set of 8 assemblies.

Revision 1 of H1C23 COLR contains limits specific to the redesigned reload core and is only valid for Mode 4, Mode 5, and Mode 6. Another revision of this COLR will be issued that will provide cycle specific COLR limits for Modes 1-3 of operation.

Implementation of this document is controlled by AD-NF-ALL-0807, Reload Design Process, Section 5.5 Reload Design Revisions.

Implementation Schedule The Harris Unit 1 Cycle 23 COLR Revision 1 requires the cycle Reload Safety Evaluation (RSE),

HNP-F/NFSA-0372, Revision 2 be approved prior to the COLR being issued. The RSE supports and references the reload 50.59 (AR# 02301421), which must be approved prior to the reload implementation and fuel loading.

Revision 1 may become effective immediately upon receipt, but must be implemented prior to fuel insertion of the switched assemblies reflective of the redesigned reload core. The Harris Unit 1 Cycle 23 COLR will cease to be effective during No MODE between cycles 23 and 24.

Data Files to be Implemented No data files are transmitted as part of this document.

HNEI-0400-0016 Harris Unit 1 Cycle 23 Revision 1 Core Operating Limits Report Page 20 4.0 OTHER REQUIREMENTS The following requirement is not identified per Technical Specification 6.9.1.6 to appear in the COLR but is presented in compliance with Amendment No. 65 issued July 24, 1996 which relocated the Movable Incore Detection System from Technical Specification 3.3.3.2 to the COLR.

4.1 Movable Incore Detection System

1.

Functionality: The Movable Incore Detection System shall be functional with:

a. At least 38 detector thimbles at the beginning of cycle (where the beginning of cycle is defined in this instance as a flux map determination that the core is loaded consistent with design),

b. A minimum of 38 detector thimbles for the remainder of the operating cycle,

c. A minimum of two detector thimbles per core quadrant, and

d. Sufficient movable detectors, drive, and readout equipment to map these thimbles.

2.

Applicability: When the Movable Incore Detection System is used for:

a. Recalibration of the Excore Neutron Flux Detection System, or

b. Monitoring the QUADRANT POWER TILT RATIO, or

c. Measurement of

(, ) and

(,, )

3.

Surveillance Requirements: The Movable Incore Detection System shall be demonstrated functional, within 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months prior to use, by irradiating each detector used and determining the acceptability of its voltage curve when required for:

a. Recalibration of the Excore Neutron Flux Detection System, or

b. Monitoring the QUADRANT POWER TILT RATIO, or

c. Measurement of

(, ) and

(,, )

(Revision 1 COLR Limits are only Applicable to Modes 4, 5, and 6)

HNEI-0400-0016 Harris Unit 1 Cycle 23 Revision 1 Core Operating Limits Report Page 21 4.1 Movable Incore Detection System (continued)

4.

Bases:

The functionality of the movable incore detectors with the specified minimum complement of equipment ensures that the measurements obtained from use of this system accurately represent the spatial neutron flux distribution of the core.

The functionality of this system is demonstrated by irradiating each detector used and determining the acceptability of its voltage curve.

For the purpose of measuring

(, ) and

(,, ), a full incore flux map is used.

Quarter core flux maps, as defined in WCAP 8648, June 1976, may be used in recalibration of the Excore Neutron Flux Detection System, and full incore flux maps or symmetric incore thimbles may be used for monitoring QUADRANT POWER TILT RATIO when one Power Range channel is INOPERABLE.

5.

Evaluation Requirements:

In order to change the requirements concerning the number and location of functional detectors, the NRC staff deems that a rigorous evaluation and justification is required. The following is a list of elements that must be part of a 50.59 determination and available for audit if the licensee wishes to change the requirements:

a.

How an inadvertent loading of a fuel assembly into an improper location will be detected,

b.

How the validity of the tilt estimates will be ensured,

c.

How adequate core coverage will be maintained,

d.

How the measurement uncertainties will be assured and why the added uncertainties are adequate to guarantee that measured nuclear heat flux hot channel factor, nuclear enthalpy rise hot channel factor, radial peaking factor and quadrant power tilt factor meet Technical Specification limits, and

e.

How the Movable Incore Detection System will be restored to full (or nearly full) service before the beginning of each cycle.

To convert to pressurizer pressure, subtract 25 psi for the pressure loss between the core exit and the pressurizer pressure and subtract 15 psi to convert psia to psig.

HNEI-0400-0016 Revision 2 Page 2 Harris Unit 1 Cycle 23 Core Operating Limits Report Implementation Instructions for Revision 2 Revision Description and AR Tracking Revision 2 of the Harris Unit 1 Cycle 23 (H1C23) Core Operating Limits Report (COLR) contain limits specific to the redesigned reload core based on the information obtained from HNP-F/NFSA-0351, Revision 2. A H1C23 core redesign was required due to elevated resistance observed during in-core RCCA drag testing for a single fuel assembly in core location F-12 as documented in AR 02300932.

The core was redesigned such that this fuel assembly and its octant-symmetric partners are exchanged with a neutronically similar set of 8 assemblies.

Revision 2 of H1C23 COLR contains limits specific to the redesigned reload core and is valid for all Modes of operation (Mode 1 thru Mode 6).

Implementation of this document is controlled by AD-NF-ALL-0807, Reload Design Process, Section 5.5 Reload Design Revisions.

Implementation Schedule The Harris Unit 1 Cycle 23 COLR Revision 2 requires the cycle Reload Safety Evaluation (RSE),

HNP-F/NFSA-0372, Revision 3 be approved prior to the COLR being issued. The RSE supports and references the reload 50.59 (AR# 02301431), which must be approved prior to the reload implementation and fuel loading.

Revision 2 may become effective immediately upon receipt, but must be implemented prior to entering Mode 3 during the EOC-22 refueling outage. The Harris Unit 1 Cycle 23 COLR will cease to be effective during No MODE between cycles 23 and 24.

Data Files to be Implemented No data files are transmitted as part of this document.
