Re:
Turkey Point Units 3 and 4
Docket Nos.
50-250 and 50-251 Proposed License Amendments Implementation of the Revised Thermal Design Procedure and Steam Generator Water Level Low-Low Set oint In accozdance with 10 CFR 50.90, Florida Power and Light Company (FPL) requests that Appendix A of Facility Operating Licenses DPR-31 and DPR-41 be amended to revise the Turkey Point Units 3 and 4 Technical Specification (TS) 2.1.1, Safety Limit Reactor Core; TS 2.2, Limiting Safety System Settings Reactor Trip System Instrumentation Setpoints; TS 3/4.2.5 Power Distribution Limits DNB Parameters; TS 3/4.3,2 Engineered Safety Features Actuation System Instrumentation and the associated BASES.
The proposed revision to the Technical Specifications includes (a) the implementation of Westinghouse's NRC approved Revised Thermal Design Procedure (RTDP),
and (b) a revision to the Steam Generator Water Level Low-Low trip setpoint.
The RTDP methodology has been previously approved by the NRC in Westinghouse topical report WCAP-11397-P-A.
This methodology provides an increase in the Departure from Nucleate Boiling (DNB) margin by convoluting statistically the uncertainties on power, pressure, temperature, flow and the DNB correlation to define the Departure from Nucleate Boiling Ratio (DNBR) limit and coze thermal limits.
These uncertainties have been calculated for Turkey Point in Westinghouse topical report WCAP-13719, which is provided as an attachment to this submittal.
FPL has determined that the proposed license amendments do not involve a significant hazards consideration pursuant to 10 CFR 50.92.
A description of the amendment request is provided in Attachment 1.
The no significant hazards determination in support of the proposed
~ Technical Specification changes are provided in Attachment 2.
Attachment 3 provides the proposed revised Technical Specifications.
Attachment 4 contains a single copy of Westinghouse Proprietary
.Report, WCAP-13719, entitled "Westinghouse Revised Thermal Design Procedure Instrument Uncertainty Methodology for Turkey Point Units 3
and 4" and a single copy of the Westinghouse Non-Proprietary Report, WCAP-13718.
Attachment 5 includes a Westinghouse authorization
- letter, CAW-95-779, accompanying affidavit, Proprietary Information
- Notice, and Copyright Notice.
Since Attachment 4 contains information proprietary to Westinghouse Electric Corporation, it is supported by an affidavit signed by Westinghouse, the owner of the information.
The affidavit sets forth the basis on which the information may be withheld from public disclosure by the Commission and addresses with specificity the 9505120124 950505 PDR ADQCK 05000250 P
