Dear Mr. Stello:

"W <rg Re: Turkey Point Unit 4 Docket, No. 50-251 DPR-'41'p Proposed Amendment to Facility 0 crating License In accordance with 10 CFR 50.30, Florida Power and Light Company submits herewith three (3) signed originals and forty (40) conformed copies of a request to amend Appendix A of Facility Operating License DPR-4 1.

This proposal is being submitted in response to a request, from your staff. The proposal is as described below and as shown on the accompanying Technical Specification page bearing the date of this letter in the lower right hand corner.

~@V A new specification 3.1.6 on Unit 4 DNB Parameters is added. This specification is similar to one previously incorporated for Unit 3.

Pages B3.1-7 and B3.1-8 A new Bases section is provided to describe one of the new DNB Parameters. Uncertainty in the flow determination method to be used is estimated to be from three'o five percent.

6. DNB Parameters Reactor Coolant Flow Measurements (4)

Elbow taps are used in the reactor coolant system as an instrument device that indicates the status of the reactor coolant flow. The basic function of this device is to provide information as to whether or not a reduction in flow rate has occurred. The correlation between flow reduction and elbow tap readout has been well estab1ished by the following equation:

AP C~ 2 (W ') where AP is the referenced pressure

'AP 0, 0 0

differential with the corresponding referenced flow rate W , and AP is the pxessure differentia1 with the 0

corresponding flow rate W. The full flow reference point is established during initial startup. The low flow trip point is then established by extrapolating along the correlation curve.
