Request for Additional Information cc w/encl: Distribution via Listserv REQUEST FOR ADDITIONAL INFORMATION FLORIDA POWER AND LIGHT COMPANY TURKEY POINT UNITS 3 AND 4 DOCKET NOS. 50-250 AND 50-251 By letter dated June 25, 2009 (Agencywide Documents Access and Management System Accession No. ML092050277), Florida Power and Light Company (the licensee) requested an amendment to Facility Operating License Nos. DPR-31 and DPR-41 for Turkey Point, Units 3 and 4. The proposed changes would revise the Turkey Point licensing bases to adopt the alternative source term (AST), as described in Title 10 of the Code of Federal Regulations (10 CFR), Section 50.67, following the guidance provided in Regulatory Guide 1.183, "Alternative Radiological Source Terms for Evaluating Design Basis Accidents at Nuclear Power Reactors," July 2000. To complete its review of the license amendment request (LAR), the Nuclear Regulatory Commission staff requests the following additional information. Describe how loads being added to the Turkey Point emergency diesel generators (EDGs) (if applicable), whether automatically (sequencer) or manually (per operating procedure), affect the capability and capacity of the EDGs (e.g., describe the impact of the proposed change on the EDG ratings) to support this LAR. Describe any changes to the EDG surveillance testing and/or how the surveillance testing demonstrates the EDG capability to supply the necessary accident loading. In addition (if load has been added), describe EDG design load margin and how that design margin is managed. Provide a list and description of components being added to your 10 CFR 50.49 program due to this LAR (if applicable).

Confirm that these components are qualified for the environmental conditions they are expected to be exposed to. The licensee proposed utilizing sodium tetraborate decahydrate stored in stainless steel baskets inside containment to control pH at 7.0 or higher, crediting Containment Spray for post-LOCA iodine removal and not crediting the Containment Filtration System in the AST dose consequences analyses.

Describe the impact of the above proposed actions on environmental conditions and any impact on equipment qualification.
