July 29, 2002 APPLICANT: Florida Power and Light Company FACILITIES: St. Lucie, Units 1 and 2
SUBJECT:
TELECOMMUNICATION WITH FLORIDA POWER AND LIGHT COMPANY TO DISCUSS INFORMATION PROVIDED TO THE NRC STAFF IN A RESPONSE FOR INFORMATION DATED JUNE 25, 2002 On July 15, 2002, a conference call was conducted between the U.S. Nuclear Regulatory Commission (NRC) staff, NRC contractor staff, and representatives of Florida Power and Light Company (hereafter referred to as FPL or the licensee) to clarify specific information provided to the NRC staff in a letter from Mr. D. Jernigan, FPL, dated June 25, 2002. The letter was in response to a request for additional information (RAI) on the subject of Severe Accident Management Alternatives (SAMA) contained in a letter from the NRC staff to FPL dated May 7, 2002. The following personnel participated in the June 25, 2002, conference call:
Michael Masnik, NRC; Jim Meyer, NRC Contractor; Kim Green, NRC Contractor; Tom Abatiello, FPL; Ching Guey, FPL; and Mamoud Heiba, FPL.
The staff asked several questions pertaining to the methodology used by FPL to identify potential SAMAs. The staff asked whether or not importance measures were used to identify or eliminate the potential SAMAs for each unit. FPL responded by stating that they relied on the risk reduction worth values to eliminate SAMAs with a risk reduction worth of less than 1.001; however, they did not use the risk reduction worth values to identify potential plant-specific SAMAs in the environmental review (ER). SAMAs with a risk reduction worth greater than 1.00 were reviewed, but no new SAMA candidates were identified. The staff also discussed with the licensee the cut-off frequency for the top 100 cut-sets evaluated.
The staff asked a number of clarifying questions that primarily reaffirmed its understanding on methodology and assumptions made by the licensee. The questions pertained to the calculation of core damage frequency, assumptions on the extrapolation of human population densities around the facility during the renewal period, the relative uncertainty between the models used and the parameters used in the PRA, and the assumptions made in the plant-specific Modular Accident Analysis Program (MAAP) related to late containment failure.
The conference call generated no open items.
