SUBJECT:
FLORIDA'OIIER AND LIGHT.,COMPAffY - TOPICAL REPORT Of< RETRAN (TAC NO.
60550)
AND TOPICAL REPORT ON PlfR PHYSICS METHODOLOGY (TAC NO. 60549)
By letter dated January 7, 1986, Florida Power and Light Company (FP8L) submitted topical report NTH-G-6 for the purpose of demonstration of technical competence to utilize the RETRAN computer code for performing systems transient analysis for the Turkey Point and St. Lucie plants.
Additional information was provided in letters dated March 2 and April 10, 1987.
The staff's review, with technical assistance from its consultant, International Technical Services, Inc., has concluded that FP8L has demonstrated the capability to utilize the RETRAN computer code to perform systems transient calculations for their plants.
However, since the subject topical report does not present details in plant-specific nodalizations, control system modeling and assumptions for the licensing
- analyses, the topical report NTH-G-6 approval is limited to only FPSL's demon-stration of competence to use the RETRAN code.
Enclosure 1 contains the staff's safety evaluation and supporting Technical Evaluation Report.
By letter dated f1ay 10,
- 1984, FP8L submitted for review a topical report entitled "PlfR Lattice Physics methods at Florida Power and Light Company."
The report was applicable for analysis associated with the Turkey Point and St. Lucie Plants.
Additional information was submitted on October 21,
- 1986, August 8, 1986, and June 26, 1987.
The report is the first of a series of three topical reports on the FPEL core physics methodology to support their'eload methods.
However, this does not include the special fuel assemblies required to meet the flux reduction commitment for the pressurized thermal shock issue for the Turkey Point Units 3 and 4.
The staff reviewed the submitted information, This review was accomplished by comparing the results of a benchmarked standard problem with the results of the same problem derived with the proposed methodology.
The standard problem is designed to test all of the essential computational capabilities of the methodology.

Mr.
M. F.
Conway The proposed methodology for the computation of the cross-sections is based on the CHEETAH program and in general follows the usual steps for similar computa-tions.
It provides group constants for diffusion and transport calculations for weakly absorbing assemblies, and for core depletion and isotopic buildup.
- However, a set of cross-sections cannot be reviewed independent'ly from a diffusion or a transport calculation and the integral type of results of such calculation, i.e., criticality, control rod worths, cycle length, etc.
There-fore, this review is limited to the procedures followed in the calculations rather than to the accuracy or acceptability of the results of these calculations.
The staff was assisted in this review by Dr. J.
Carew of Brookhaven National Laboratory (BNL) who ran the standard problem with the Florida Power and Light input.
Enclosure 2 contains the staff's safety evaluation.
'ased upon the above, the staff's review of the subject topical reports is completed.
If FP&L desires additional analysis on the above subject, (e.g.,
methodology approval for RETRAN), appropriate submittals can be made and the staff will review them accordingly.
Sincerely,
