January 8, 2004 MEMORANDUM TO: Biweekly Notice Coordinator FROM: Darl S. Hood, Senior Project Manager, Section 1 /RA/

Project Directorate III Division of Licensing Project Management

SUBJECT:

REQUEST FOR PUBLICATION IN BIWEEKLY FR NOTICE -

NOTICE OF ISSUANCE OF AMENDMENT TO FACILITY OPERATING LICENSE (TAC NO. MB7791)

Nuclear Management Company, LLC, Docket No. 50-255, Palisades Plant, Van Buren County, Michigan Date of application for amendment: October 17, 2002, as supplemented December 10, 2003.

Brief description of amendment: The amendment revises Technical Specification Table 3.3.1-2 by modifying a constant in the variable thermal margin/low pressure (TM/LP) trip equation. The change reduces calculated values for the variable TM/LP trip setpoint, and results from improvements in plant equipment used to establish the TM/LP trip setpoint.

Ultrasonic feedwater flow measurement devices, which were recently installed at Palisades, result in less uncertainty applied in the methodology used for determining core power level.

The devices used to calculate the TM/LP trip setpoint were previously replaced with digital thermal margin monitors having less uncertainty.

Date of issuance: January 8, 2004.

Effective date: As of the date of issuance and shall be implemented within 90 days.

Amendment No.: 214 Facility Operating License No. DPR-20. Amendment revised the Technical Specifications.

Biweekly Notice Coordinator Date of initial notice in FEDERAL REGISTER: September 2, 2003 (68 FR 52235)

The Commission's related evaluation of the amendment is contained in a Safety Evaluation dated January 8, 2004.

No significant hazards consideration comments received: No.
