BOX 14000, JUNO BEACH, F L 3340B Jr~:ii FLORIDA POWER 8 LIGHT COMPANY JAN Q 7 1888 L-86-4 Office of Nuclear Reactor Regulation Attention:
Mr. Herbert N. Berkow, Chief Standardization and Special Project Directorate U. S. Nuclear Regulatory Commission Washington, D. C. 20555
Dear Mr. Berkow:
Re: To ical Re ort - RETRAN Code Transient Anal sis Model Qualification We are transmitting herewith twenty-three (23) copies of the Topical Report, "RETRAN Code Transient Analysis Model Qualification" for your review and approval.
The attached Topical Report is submitted for,thepurpose of qualifying FPL's RETRAN models fo'r non-LOCA system"".safety analyses in support of future licensing 's'ubmittals for,"Turk'ey"Point Units 3 'and"4'a'n'd'St.
Lucie Units I and 2, Docket Numbers'0-250, 50-25 I, "50-335," and 50-389, respectively.
A Topical Report on FPL's core thermal-hydraulic
- codes, models and methods will be submitted at a later date.
, C FPL desires to have the capability of supporting licensing amendments during I 986 and l987 which have the objective of increasing the safety, availability and operating flexibility of the Turkey Point and St. Lucie nuclear plants.
It is our objective to have the flexibility to support any non-LOCA safety analyses in-house, utilizing computer models and methods developed at FPL since the mid-l970's.
Currently, FPL's system simulation is performed with the RETRAN Code developed by the Electric Power Research Institute and approved for non-LOCA analysis by the NRC.
In parallel with the qualification of FPLs thermal-hydraulics methods, an effort is ongoing to qualify FPL's core physics methods for use in safety-related licensing applications.
A topical report on P WR lattice physics methods was submitted on May I 0, I 984 (FPL Letter L-84-I25),
and additional reports on FPL's physics models and methods will be submitted in early l986. It is the aim of this effort to eventually qualify FPL's methods for performing most non-LOCA safety-related plant analysis, including reload analysis, for its nuclear plants.
