Re: St. Lucie Unit 1 Docket No. 50-335 Proposed. License Amendment Low Steam Generator Level Reactor Trip and Automatic Feedwater Actuation S stem Set pints In accordance with 10 CFR 50.90, Florida Power & Light Company (FPL) submits herewith a request to amend Facility Operating License DPR-67.

The proposed amendment revises Technical Specifications 2.2.1, Reactor Trip Setpoints, and 3/4.3.2, Engineered Safety Feature Actuation System Instrumentation. The proposed change lowers the Reactor Protective System Steam Generator Level-Low trip setpoint from >37.0% narrow range to >20.54 narrow range. The Auxiliary Feedwater Actuation System setpoint for the Steam Generator Level-Low trip is lowered from its current value of >29.0< narrow range to >19.04 narrow range. A change is also being proposed to reduce the auxiliary feedwater system response time on low steam generator level. Additionally, the proposed change revises the allowable values for steam generator and feedwater header high differential pressure for auxiliary feedwater initiation.

Marked up copies of the affected Technical Specification pages are included as Attachment 1. A Safety Analysis in support of the proposed amendment is included as Attachment 2. A "Determination of No Significant Hazards Consideration" is provided as Attachment

3. Section 4.0 of an Advanced Nuclear Fuels Corporation report entitled "St. Lucie Unit 1 Loss-of-Feedwater Transient with Reduced Steam Generator Level-Low Trip Setpoint" is included as Attachment 4
