The proposed amendments would authorize increasing the licensed core power levels for Sf. Lucie Units 1 and 2 from 2700 megawatts thermal (MWt) to 3020 MWt. The increase in core thermal power will be approximately 12 percent, including a 10-percent power uprate and a 1.7 -percent measurement uncertainty recapture, over the current licensed core thermal power level and is categorized as an Extended Power Uprate.

LUCIE PLANT, UNITS 1 AND 2 - ENVIRONMENTAL ASSESSMENT AND FINDING OF NO SIGNIFICANT IMPACT RELATED TO THE PROPOSED EXTENDED POWER UPRATE (TAC NOS. ME5091 AND ME5843)
Dear Mr. Mueller:
Enclosed is a copy of the Environmental Assessment and Finding of No Significant Impact related to Florida Power and Light Company's applications for amendments dated November 22, 2010, for St. Lucie Unit 1, and February 23, 2011, for St. Lucie Unit 2, and subsequent supplements. The proposed amendments would authorize increasing the licensed core power levels for St. Lucie Units 1 and 2 from 2700 megawatts thermal (MWt) to 3020 MWt.
The increase in core thermal power will be approximately 12 percent, including a 10-percent power uprate and a 1.7-percent measurement uncertainty recapture, over the current licensed core thermal power level and is categorized as an Extended Power Uprate.
The assessment was published in the Federal Register on July 6, 2012 (77 FR 40092). If you have any questions, please contact me by phone at 301-415-2788 or by email at Tracy.Ort@nrc.gov.
Sincerely, IRA!
