By letter L-2009-133 dated June 25, 2009 [Reference 1], Florida Power and Light (FPL) requested to amend Facility Operating Licenses DPR-31 and DPR-41 and revise the Turkey Point Units 3 and 4 Technical Specifications (TS). The proposed amendments revise the TS to adopt the Alternative Source Term (AST) as allowed in 10 CFR 50.67.

Turkey Point Units 3 and 4 L-2010-136 Docket Nos. 50-250 and 50-251 Page 2 of 3 The meteorological data for 2003-2007 originally used to support the AST License Amendment Request (LAR) was transmitted to the NRC staff by letter dated July 21, 2009

[Reference 2]. Subsequent NRC review of this meteorological data resulted in questions regarding the quality of the data as submitted for this period [References 3, 4]. Based on further evaluation of this data, FPL decided to revise the meteorological data set to include more recent meteorological data from years 2008-2009 that was not previously available.

On June 11, 2010, FPL submitted revised meteorological data for years 2005-2009

[Reference 5]. Resolution of the quality issues raised regarding the calibration of the meteorological tower temperature sensors has resulted in a conservative decision to bias vertical temperature differentials (AT) with the average (mean) calculated value for each channel over each calibration interval for the hourly meteorological data. On June 23, 2010, FPL provided its RAI response by letter L-2010-131 in which the basis for using the temperature biased meteorological data was discussed in detail [Reference 6].

Enclosed is a compact disc (CD) titled "Turkey Point AST LAR 196, Temperature Biased Meteorological Data, FPL Letter L-2010-136," that includes Turkey Point Units 3 and 4 AT biased meteorological data encompassing the five year period from January 2005 through December 2009. The data is provided in two different formatted ASCII files. The Format 1 files (.met) contain the hourly meteorological data after quality verification and reformatting of the data for input to ARCON96. The Format 2 files contain the hourly meteorological data formatted in accordance with Appendix A to RG 1.23, Rev 1 and NUREG-0917. In this second format the applicable stability class (1 - 7) has been added to the last (unused) field in the data file to facilitate NRC's review of the data. The stability class is derived from the indicated AT between the 1OM and 60M elevations, with a preference towards using the Channel "A" instruments. Also provided are the ARCON96 card image input (.rsf) files and printed output (.log) files. A listing of all ARCON96 cases is in the Release/Receptor Combination Table in Attachment 2 of PTN-ENG-SENS 052, Rev 2 (enclosure to FPL letter L-2009-163) [Reference 2]. FPL submitted the revised AST radiological dose consequences by letter L-2010-137 on June 25, 2010 [Reference 7].

The averaged AT value for each channel will be applied as a bias or correction factor to the hourly meteorological data. The effects of this correction will be small shifts in the calculated stability classes for the hourly meteorological data and result in small changes to the calculated atmospheric dispersion factors (X/Qs). When the resultant AT biased X/Q values exceed the unbiased X/Qs, the more conservative value will be used. This technical approach will assure conservative radiological dose consequences for the AST analyzed design basis accidents.

The attachment to this letter provides the list of the files contained on the enclosed CD.

In accordance with 10 CFR 50.91(b)(1), a copy of this letter is being forwarded to the State Designee of Florida.

This submittal does not alter the significant hazards consideration or the environmental assessment previously submitted by FPL letter L-2009-133 [Reference 1].
