Re:
Turkey Point Units 3 and 4 Docket Nos. 50-250 and 50-25 I Request for Additional Information Boraflex Our letter L-87-279, dated July IO, l987, provided the results of a sensitivity analysis performed for Turkey Point Units 3 and 4 spent fuel racks.
This analysis was performed to show the affect of postulated gaps on maintaining the 0.95 K ff shutdown criteria.
The analysis shows that Florida Power 6 Light (FPL) will be able to maintain the 0.95 Keff shutdown criteria for future fuel cycles, assuming that each Boraflex plate has gaps of 3.5 inches and each storage cell in the fuel racks has on assembly with an enrichment of 4.I%.
There are no indications of gaps as a result of the blackness testing at Turkey Point, and the enrichment of the new fuel currently used at Turkey Point ranges from 3.4% to 3.6%.
Under FPL's fuel management program and the current limits on reactor operations, FPL will only be able to increase the maximum Turkey Point fuel enrichment in small increments (approximately 0.2%) each cycle.
Therefore, at the time of the next blackness testing and surveillance of the Boraflex in approximately three years, the maximum fuel enrichment at Turkey Point will be less than 4.I%.
Prior to completion of that surveillance, FPL will not store fuel with an enrichment greater than 4. I%.
Should there be any questions, please contact us.
Very truly yours, C.. Wood Group Vice President Nuclear Energy COW/RG/gp y4Dof 1 o an FPL Group company
