As!.this letter' states, FPL believes that thr. Boraflex at Turkey Point.is acceptable for continued use.
The purpose of'the letter was only to indicate that there are several possible actions which could be'taken to assure the continued. safe. storage of fuel at Turkey. Point if the Boraflex were to experience degradation.
Sincerely,

Request for AdditionalInformation Boroflex Usooe in Spent Fuel Pools Mc ', m,'
e.r.; -
C Your letter dated June 9,1987 requested information concerning the use of Boroflex poison material in the spent fuel storage rocks et Turkey Point Units 3 and 4. Florido Power & Light provided a response to those questions by our letter L-87-279 dated July 10, 1987.
As this response explains, FPL considers the Boroflex to be occeptable for continued use.
FPL will be performing a surveillance test, known as Blockness Testing, on these rocks and will provide the results of this surveillance to the stoff. The purpose of this letter is to provide additional information in response to NRC Stoff question regarding the existence of possible options if degradation of the Boroflex were to occur.
FPL has completed a review of possible options if degraded Boroflex poison is discovered by our surveillance program.
I)
The degroded Boroflex could be evoluoted to determine whether the degrodotion and any expected future degrodotion would adversely offect FPL's ability to satisfy the.95 K,gg limit for the Turkey Point spent fuel pools. If the pools could still sotisfy this limit, no further oction would be necessar y.
2)
Administrative controls could be imposed on the placement of new fuel assemblies around storage cell locations that have degroded Boroflex. The sensitivity onelysis performed for Turkey Point Units 3 and 4 assumes only new fuel with 4.5 w/o fuel is stored in the spent fuel pool. By limiting the amount and location of the storoge of new fuel assemblies and by inserting spent fuel between the new fuel, FPL could reduce the K,gg to less than or equal to.95.

' U. S. Nuclear Regulatory Commmission L.47 313 Page two 3)
A poison material similar to o control rod or burnable poison could be odded to any new fuel nssembly to be ploced in a storage cell with degraded Boroflex. This would reduce the K,gg to less than or equal to the.95 limit.
4)' Poisen plates could be odded into the spoce between the fuel ossembly ond the cell wall to assure o K,gg of less than or co.uol to.95.
- 5) FPL hos token no credit for the 1950 ppm boron concentration in the spent fuel pool water. This boron concentration alone assures a K,gg of less than
.90.
In order to take credit for this boron, FPL could establish various administrative controls to provide o high level of confidence that the spent fuel pool water will remain borated. These controls could include isolating pure water sources and routine sompling of the boron concentration.
- 6) The storage cells with the degraded Boroflex could be blocked off to prevent fooding of any fuel assembly into the cell.
- 7) The storage rocks with the degraded Boroflex could be coated with boron with a sufficient density to assure o K,gg of less than or equal to.95.
- 8) The storage rocks which contain degraded Boroflex could be replaced.
It shou d be emphasized the FPL believes that the Boroflex of Turkey Point is l
acceptable for continued use and that no changes will be necessary in the manner in which FPL plans to store fuel at Terkey Point. The purpose of this letter is only to indicate that there ore several possible octions which could be token to assure *he continued safe storoge of fuel of Turkey Point if the Boroflex in the spent fuel rocks were to experience degrodotion.
Should there be any further questions, please contact us.
