A value of 2.OE-04 pCi/ml is used as the ECL for dissolved and entrained noble gases in liquid effluents.

FLORIDA POWER & LIGHT COMPANY ST. LUCIE UNITS 1 AND 2 ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT JANUARY 1, 2012 THROUGH DECEMBER 31, 2012 Measurements and Approximations of Total Radioactivity Measurements of total radioactivity in liquid and gaseous radioactive effluents were accomplished in accordance with the sampling and analysis requirements of Tables 4.11-1 and 4.11-2, respectively, of the St. Lucie ODCM. Estimates of errors are in accordance with Methodology Section 4.4, of the ODCM.The estimate of errors associated with values reported is as follows: LIQUID GASEOUS Error Topic Avg. % Max. % Avg. % Max. %Release Point Mixing 2 5 NA NA Sampling 1 5 2 5 Sample Preparation 1 5 1 5 Sample Analysis 3 10 3 10 Release Volume 2 5 4 15 Total % 9 30 10 35 (above values are examples only)The predictability of error for radioactive releases can only be applied to nuclides that is predominant in sample spectrums.

Nuclides that are near background relative to the predominant nuclides in a given sample could easily have errors greater than the above listed maximums.Liquid Radioactive Effluents Each batch release was sampled and analyzed for gamma emitting radionuclides using gamma spectroscopy, prior to release. Composite samples were analyzed monthly for tritium and gross alpha radioactivity in the onsite laboratory using liquid scintillation and air ion chamber counting techniques, respectively.

Composite samples were analyzed quarterly for Sr-89, Sr-90, Fe-55, Ni-63 and C-14 by a contract laboratory.

The results of the composite analyses from the previous month or quarter were used to estimate the quantities of these radionuclides in liquid effluents during the current month or quarter. The total radioactivity in liquid effluent releases was determined from the measured and estimated concentrations of each radionuclide present and the total volume of the effluent released during periods of discharge.

FLORIDA POWER & LIGHT COMPANY ST. LUCIE UNITS I AND 2 ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT JANUARY 1, 2012 THROUGH DECEMBER 31, 2012 Gaseous Radioactive Effluents Each gaseous batch, the release was sampled and analyzed for radioactivity prior to release. For releases from Gas Decay Tanks, noble gas grab samples were analyzed for gamma emitting radionuclides using gamma spectroscopy.

For releases from the Containment Buildings, samples were taken of noble gas and tritium grab samples, and analyzed for gamma emitting radionuclides prior to each release. The results of the analyses and the total volume of effluent released were used to determine the total amount of radioactivity released in the batch mode.For continuous effluent release pathways, noble gas and tritium grab samples were collected and analyzed weekly for gamma emitting radionuclides by gamma spectroscopy and liquid scintillation counting techniques, respectively.

Continuous release pathways were continuously sampled using radioiodine adsorbers and particulate filters. The radioiodine adsorbers and particulate filters were analyzed weekly for gamma emitting radionuclides using gamma spectroscopy.

Results of the noble gas and tritium grab samples, radioiodine adsorber and particulate filter analyses from the current week and the average effluent flow rate for the previous week were used to determine the total amount of radioactivity released in the continuous mode. Monthly composites of particulate filters were analyzed for gross alpha activity, in the onsite laboratory using the air ion chamber counting technique.

Quarterly composites of particulate filters were analyzed for Sr-89 and Sr-90 by a contract laboratory.

Meteorological Monitoring Program In accordance with ODCM Administrative Control 3.11.2.6.b., a summary of hourly meteorological data, collected during 2012, is retained onsite.This data is available for review by the NRC upon request. During 2012, the goal of >90% joint data recovery was met. Actual meteorological collected during the year was used in the offsite dose calculations in this report.Carbon-14 Dose Estimation The estimate of carbon- 14 (C-14) released from the St. Lucie Nuclear Plant was derived from the EPRI document, "Estimation of Carbon-14 in Nuclear Power Plant Gaseous Effluents," Report 1021106, issued December 2010.The site specific source term values used in the St. Lucie calculations were taken from Section 4-28 of the report, and employed the proxy generation rate values for a Combustion Engineering reactor. The actual 2012 operating data for the units was employed for the calculations to derive the total curies released for each unit.

FLORIDA POWER & LIGHT COMPANY ST. LUCIE UNITS 1 AND 2 ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT JANUARY 1, 2012 THROUGH DECEMBER 31, 2012 Carbon-14 Dose Estimation (continued)

The total amount of C-14 released in 2012 for Unit 1 was 6.68 Ci, and the total amount of C-14 released in 2012 for Unit 2 was 7.53 Ci. The highest calculated dose is found to be "Bone Dose" to a "Child" through"Inhalation".

The total combined dose from C-14 through this pathway is 1.OIE-01 mrem/yr.Additionally, a "Child" consuming vegetables from the garden located at 2.0 miles in the WSW direction from the plant would have received a total combined "Bone Dose", including C-14, of 1.01E-1 mrem/yr.Using the same release values, the dose to a visitor on site (Adult Lifeguard) is found to be 4.35E-01 mrem/yr, Total Body dose.All C-14 dose calculations are based on Regulatory Guide 1.109 values.This is a fraction of the I mrem annual whole body dose received to the average US citizen from natural occurring Carbon-14, primarily generated through cosmogenesis in the terrestrial biosphere (Reference National Council of Radiation Protection Report 45, Natural Background Radiation in the United States).2.0 SUPPLEMENTAL INFORMATION 2.1 Abnormal Releases or Abnormal Discharges There were two abnormal (unplanned) releases or discharges from the site during the report period. Both releases were due to leaks associated with the gas analyzer in the Unit 1 Waste Gas Decay Tank system. In both cases, the equipment deficiencies were corrected and the gas analyzer was returned to service. Both of the unplanned releases were monitored by the Plant Vent Monitor that is installed on the Plant Vent Stack. Neither release challenged or exceeded site release or dose limits. Both releases are included in the gaseous portion of the tables, and are included in the site's dose calculations for the year.2.2 Non-Routine Planned Discharges No non-routine planned discharges were made during the report period.2.3 Radioactive Waste Treatment System Changes No changes wer'e made to the waste treatment system during the report period.2.4 Annual Land Use Census Changes There were no changes to the Land Use Census during 2012.

FLORIDA POWER & LIGHT COMPANY ST. LUCIE UNITS 1 AND 2 ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT JANUARY 1, 2012 THROUGH DECEMBER 31, 2012 2.5 Effluent Monitoring System Inoperability There were no effluent monitors out of service for greater than 30 days.2.6 Offsite Dose Calculation Manual Changes Three revisions were made to the St. Lucie ODCM during the report period. The first revision was to change a procedure reference number to the new number used by the site. The second revision was to change the stated thermal megawatt output for Unit I after the power up-rate project.The third revision was to change the stated thermal megawatt output for Unit 2 after its power up-rate project.2.7 Process Control Program Changes There were no changes to the Process Control Program during the report period.2.8 Corrections to Previous Reports None 2.9 Other Ten batch releases were made from the South Settling Basin to the Intake Canal during the year to lower the water level due to approaching severe weather. All ten releases were analyzed according to the ODCM and site procedural requirements and were found to have no alpha, gamma, tritium or hard to detect isotopes.

The releases are listed below: Release start date Volume of release May 17 5.97E6 gallons June 1 1.05E7 gallons June 12 1.05E7 gallons June 25 1.07E7 gallons August 22 1.94E7 gallons September 15 4.60E6 gallons September 22 6.97E6 gallons October 19 5.26E6 gallons November 13 2.92E6 gallons December 12 3.19E5 gallons A modification was made in the fourth quarter of 2012 to the discharge point for the South Settling Basin. A manual valve and flow measuring device were installed to more accurately control and account for the discharges from this pathway. The last discharge of the year was made to perform post maintenance testing of the new system to ensure satisfactory operation of the newly installed components.
