2022 -- Turkey Point Annual Radioactive Effluent Release Report calendar quarter and shall not exceed 15 mrem to any organ during any calendar year. C-14 dose was calculated using the guidance of Regulatory Guide 1.109, Calculations of Annual Doses to Man from Routine Releases of Reactor Effluents for the purpose of Evaluation Compliance with 10 CFR Part 50, Appendix I, Rev1, Oct 1977.

2.0 EFFLUENT CONCENTRATION Water : In accordance with 10 CFR 20, Appendix B, Table 2, Column 2, and for entrained or dissolved noble gases as described in 1.1 of this report.

Air : Release concentrations are limited to dose rate limits described in 1.2 cut this report.

3.0 AVERAGE ENERGY The average energy of fission and activation gases in effluents is not applicable.

4.0 MEASUREMENTS AND APPROXIMATIONS OF TOTAL ACTIVITY All liquid and airborne discharges to the environment during this period were analyzed in accordance with Technical Specification requirements as stated in the Offsite Dose Calculation Manual (ODCM). The minimum frequency of analysis as required by Regulatory Guide 1.21 was met or exceeded.

4.1 Liquid Effluents Aliquots of representative pre-release samples, from the waste disposal system, were isotopically analyzed for gamma-emitting isotopes on a multichannel analyzer.

Frequent periodic sampling and analysis were used to determine if radioactivity was being released via the steam generator blowdown system and the storm drain system. Environmental sampling is performed in accordance with the ODCM and corporate policy.

Monthly and quarterly composite samples for the waste disposal system were prepared to give proportional weight to each liquid release made during the designated period of accumulation. The monthly composite was analyzed for tritium and gross alpha radioactivity. Tritium was determined by use of liquid scintillation techniques, and gross alpha radioactivity was determined by use of a solid-state scintillation system. The quarterly composite was analyzed for strontium 89 (Sr-89), strontium 90 (Sr-90), nickel 63 (Ni-63), and iron 55 (Fe-55) by chemical separation. Canal Evaporation dose calculations were done in accordance with the ODCM Section 2.0 Radioactive Liquid Effluents (p. 2-35).

Page 4 of 48

2022 -- Turkey Point Annual Radioactive Effluent Release Report All radioactivity concentrations determined from sample analysis of a pre-release composite were multiplied by the total represented volume of the liquid waste released to determine the total quantity of each isotope and of gross alpha activity released during the compositing period.

Aliquots of representative samples from the waste disposal system were analyzed on a pre-release basis by gamma spectral analysis. The resulting isotope concentrations were multiplied by the total volume released in order to estimate the total dissolved gases released.

The liquid waste treatment system is shared by both units at the site and generally, all liquid releases are allocated on a 50/50 basis to each unit respectively.

4.2 Gaseous Effluents Airborne releases to the atmosphere occurred from the following sources:

- Gas Decay Tanks

- Containment Purges

- RWST via vent line

- U3 and U4 Equipment hatch during outages

- Releases incidental to operation of the plant

- Canal Evaporation Releases The techniques employed in determining the radioactivity in airborne releases are:

a) Gamma spectral analysis for fission and activation gases, b) Removal of particulate material by filtration and subsequent gamma spectral analysis, Sr-89, Sr-90 determination, and gross alpha determination, c) Absorption of halogen radionuclides on a charcoal filter and subsequent gamma spectral analysis.

d) Analysis of water vapor in a gas sample for tritium using liquid scintillation techniques.

e) C-14 curies were calculated using the guidance of Estimation of C-14 in Nuclear Power Plant Gaseous Effluents, TR 1021106, EPRI, Palo Alto, CA: 2010 Both units share portions of the liquid and gaseous waste treatment system and generally, all treated waste from eacr reactor are allocated on 50/50 ratio.

Meterological data for the period January 2022 through december 2022, in the form Frequency Distribution Tables, are maintained on-site.

2022 -- Turkey Point Annual Radioactive Effluent Release Report 4.3 Estimation of Errors a) Sampling Error The error associated with volume measurement devices, flow measuring devices, etc., based on calibration data and design tolerances has been conservatively estimated to be collectively less than +/- 10%.

b) Analytical Error Our Q.C. Cross-Check Program involves counting unknown samples provided by an independent external lab. The errors associated with our analysis of these unknown samples, reported to us by the independent lab, were used as the basis for deriving the following analytical error terms:

NUCLIDE TYPE ERROR MAXIMUM ERROR Liquid +/- 2.59% +/-7.52%

Gaseous +/- 6.92%

+/- 3.31%

5.0 BATCH RELEASES See attached Open Effluent Management Software report.

6.0 UNPLANNED RELEASES 6.1 Liquid Release Occurrences AR (02433824): Unplanned Release; Water was observed flowing from an open valve, 3-713G, 3A CCW Heat Exchanger Vent. This corresponded with the lowering of the 3CCW Head Tank Level. The valve was closed isolating the vent flow by the SNPO after obtaining Control Room concurrence. U3 CCW was sampled 8/8/22 @ 0424 and indicated Na-24 at 1.76E- 7 uCi/mL and a concentration of H-3 at 4.78E-5 uCi/mL. The water from 3-713G, 3A Heat Exchanger Vent, was not captured and allowed to flow to a floor drain which leads out to the North East Storm drain. Total curies from unplanned liquid release was conservtively 4.78E-11 curies. See table 6A.

2022 -- Turkey Point Annual Radioactive Effluent Release Report 6.2 Gaseous Release Occurrences There were no unplanned gaseous release occurrences.

7.0 REACTOR COOLANT ACTIVITY 7.1 Unit 3 Reactor coolant activity limits of 0.25 µCi/gram Dose Equivalent I-131 and 447.7

µCi/gram Dose Equivalent Xenon (Xe-133) were not exceeded during this reporting period.

7.2 Unit 4 Reactor coolant activity limits of 0.25 µCi/gram Dose Equivalent I-131 and 447.7

µCi/gram Dose Equivalent Xe-133 were not exceeded during this reporting period.

8.0 SITE RADIATION DOSE The assessment of radiation dose from radioactive effluents to the general public due to their activities inside the site boundary assumes a visitor was at the child development center/fitness center for ten hours a day, five days each week for fifty weeks of the year, receiving exposure from both Unit 3 and Unit 4 at Turkey Point.

The child development center/fitness center is located approximately 1.75 miles WNW of the plant. Specific activities used in these calculations are the sum of the activities listed in the attached Unit 3 and Unit 4 Reg. Guide 1.21 tables. All dose to the public where a fraction of the limits and dose were maintained as low as reasonably achievable. The total calculated off-site dose to the public is summarized in the following Table A-5 per EPA 40 CFR 190 Individual in the Unrestricted Area.
