Dear Mr. Plunkett:
e By letter dated December 12, 1996; Florida Power and Light Company (FPL) requested, among other things, an exemption from certain, technical requirements of 10 CFR Part 50, Appendix R, for the control building roof (fire zone 106R).
By letter dated February 24, 1998, the U.S. Nuclear Regulatory Commission (NRC) staff denied FPL's exemption request for this fire zone based on the uncertainty of the roof combustibility and the unknown fire classification.
Subsequently, by letter dated November 2, 1998, FPL submitted additional information regarding the classification of the control building roof, fire zone 106R.
e The NRC staff has reviewed the information provided by FPL and finds that further clarification.is needed before the review of the exemption request can be completed.
Enclosed is the staff request for additional information (RAI). The enclosed RAI has been discussed with Olga Hanek of your staff. A target date for your response has been agreed upon to be 60 days from your receipt of this RAI.
Should a situation occur that prevents you from meeting the target date, please contact me at (301) 415-1496.
