LUCIE UNITS 1 AND 2 ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT JANUARY 1, 2013 THROUGH DECEMBER 31, 2013 1.0 PROGRAM DESCRIPTION Regulatory Limits The ODCM Radiological Effluent Control limits applicable to the release of radioactive material in liquid and gaseous effluents are described in the following sections.Fission and Activation Gases (Noble Gases)The dose rate due to radioactive materials released in gaseous effluents from the site to areas at and beyond the site boundary shall be limited to less than or equal to 500 mrems/yr to the whole body and less than or equal to 3000 mrems/yr to the skin.The air dose due to noble gases released in gaseous effluents, from each unit, to areas at and beyond the site boundary shall be limited to the following:

a. During any calendar quarter: Less than or equal to 5 mrads for gamma radiation and less thah or equal to 10 mrads for beta radiation, and b. During any calendar year: Less than or equal to 10 mrads for gamma radiation and less than or equal to 20 mrads for beta radiation.

Iodine-131, Iodine-133, Tritium, Carbon-14 and Radioactive Material in Particulate Form The dose rate due to iodine-131, iodine-133, tritium and all radionuclides in particulate form with half lives greater than 8 days, released in gaseous effluents from the site to areas at and beyond the site boundary, shall be limited to less than or equal to 1500 mrem/yr to any organ.The dose to a MEMBER OF tHE PUBLIC from iodine-131, iodine-133, tritium, carbon-14 and all radionuclides in particulate form with half lives greater than 8 days, in gaseous effluents released, from each unit, to areas at and beyond the site boundary, shall be limited to the following:

a. During any calendar quarter: Less than or equal to 7.5 mrems to any organ, and b. During any calendar year: Less than or equal to 15 mrems to any organ.

FLORIDA POWER & LIGHT COMPANY ST. LUCIE UNITS 1 AND 2 ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT JANUARY 1, 2013 THROUGH DECEMBER 31, 2013 Liquid Effluents The concentration of radioactive material released in liquid effluents to unrestricted areas shall be limited to 10 times the concentrations specified in 10 CFR Part 20, Appendix B, Table 2, Column 2 for radionuclides other than dissolved or entrained noble gases. For dissolved or entrained noble gases, the concentration shall be limited to 2.0E-4 pCi/ml total activity.The dose or dose commitment to a MEMBER OF THE PUBLIC from radioactive materials in liquid effluents released, from each unit, to unrestricted areas shall be limited: a. During any calendar quarter to less than or equal to 1.5 mrems to the whole body and to less than or equal to 5 mrems to any organ, and b. During any calendar year to less than or equal to 3 mrems to the whole body and to less than or equal to 10 mrems to any organ.Total Dose The annual (calendar year) dose or dose commitment to any MEMBER OF THE PUBLIC due to releases of radioactivity and to radiation from uranium fuel cycle sources shall be limited to less than or equal to 25 mrems to the whole body or any organ, except the thyroid, which shall be limited to less than or equal to 75 mrems.Effluent Concentration Limits Gaseous Effluents For gaseous effluents, effluent concentration limits (ECL) values are not directly used in release rate calculations since the applicable limits are expressed in terms of dose rate at the site boundary.Liquid Effluents The values specified in 10 CFR Part 20, Appendix B, Table 2, Column 2 are used as the ECL for liquid radioactive effluents released to unrestricted areas. A value of 2.OE-04 pCi/ml is used as the ECL for dissolved and entrained noble gases in liquid effluents.

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.

FLORIDA POWER & LIGHT COMPANY ST. LUCIE UNITS 1 AND 2 ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT JANUARY 1, 2013 THROUGH DECEMBER 31, 2013 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 I 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 are 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.

Gaseous Radioactive Effluents Each gaseous batch, 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.

FLORIDA POWER & LIGHT COMPANY ST. LUCIE UNITS 1 AND 2 ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT JANUARY 1, 2013 THROUGH DECEMBER 31, 2013 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 2013, is retained onsite.This data is available for review by the NRC upon request. During 2013, the goal of >90% joint data recovery was met. Actual meteorological data collected during the year was used for 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 2013 operating data for the units was employed for the calculations to derive the total curies released for each unit.The total amount of C-14 released in 2013 for Unit I was 9.17 Ci, and the total amount of C-14 released in 2013 for Unit 2 was 11.32 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 1.55E-01 mrem/yr.

FLORIDA POWER & LIGHT COMPANY ST. LUCIE UNITS 1 AND 2 ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT JANUARY 1, 2013 THROUGH DECEMBER 31, 2013 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 1.55E-1 mrem/yr.Using the same release values, the dose to a visitor on site (Adult Lifeguard) is found to be 4.17E-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 by 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 no abnormal (unplanned) releases or discharges from the site during the report period.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 were made to thewaste treatment system during the report period.2.4 Annual Land Use Census Changes There were two changes to the Land Use Census during 2013. Two gardens located in the West Northwest (WNW) sector at 4.0 and 4.2 miles from the plant site were identified during the Land Use Census. The garden located 4.0 miles from the plant is approximately 25' x 30' and grows sweet potatoes, lettuce, cabbage and greens. The garden located 4.2 miles from the plant is approximately 15' x 50' and grows tomatoes, lettuce and cabbage.2.5 Effluent Monitoring System Inoperability There were no effluent monitors out of service for greater than 30 days.

FLORIDA POWER & LIGHT COMPANY ST. LUCIE UNITS 1 AND 2 ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT JANUARY 1, 2013 THROUGH DECEMBER 31, 2013 2.6 Offsite Dose Calculation Manual Changes Three revisions were made to the St. Lucie ODCM during the report period. The first revision was an administrative change to clarify the sample collection frequency for crustacean, fish and broad leaf vegetation.

The second and third revisions were to update procedure reference numbers, and did not change the intent of the procedure.

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 Six batch releases were made from the South Settling Basin to the Intake Canal during the year to lower the water level from periods of higher than normal rainfall.

All six 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 23 3.24E4 gallons June 6 3.30E6 gallons September 12 3.19E6 gallons September 24 1.42E6 gallons November 21 9.09E6 gallons December 6 3.19E6 gallons 2.10 Groundwater Protection Program (next 2 pages) 2013 PSL Ground Water Well Results for Annual Report H3 Jan H3 Feb H3 Mar H3 Apr H3 May H3 June H3 July H3 Aug H3 Sept H3 OCT H3 NOV H3 Dec 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 L tU pCill pCi/I pCi/I pC i/I pCi/I pCill pCill pCi/I pCill pCi/I pCi/I pCi/I MW-3 633 392 524 681 MW-4 .635 482 423 370 540 798 711 MW-5 <MDC <MDC <MDC <MDC MW-6 1710 1690 1830 1920 1520 1640 1450 MW-7 <MDC <MDC <MDC 283 MW-15 3050 1220 923 571 517 MW-16 285 300 414 .347 MW-17 1110 1060 1230 2000 833 1680 726 MW-18D 1400 1900 1350 1120 1010 832 688 MW-19 <MDC <MDC <MDC <MDC MW-22D <MDC 459 403 213 MW-26 <MDC <MDC <MDC <MDC RW-2 392 498 440 272 419 201 338 RW-4 <MDC <MDC .<MDC <MDC <MDC RW-5 <MDC <MDC <MDC <MDC MW-30 427 290
