Reference:

FPL letter L-2022-023 dated February 23, 2022: 2021 Annual Radioactive Effluent Release Report By letter dated February 23, 2022 (Reference), Florida Power & Light submitted the 2021 Annual Radioactive Effluent Release Report (ARERR) for St. Lucie Units 1 and 2 pursuant to 10 CFR 50.36a(a)(2) and Technical Specification (TS) 6.9.1.7. The 2021 report provided information for the 12-month period beginning January 1, 2021 and ending December 31, 2021.

Dose calculation errors were found in the land use exposure pathways. Also, an effluent radiation monitor that had been out of service for greater than 30 days should have been reported in Section 2.5. Both items have been corrected and are provided in this submittal. This corrected report replaces the St. Lucie 2021 ARERR report in its entirety.

If you have any questions regarding this submittal, please contact Kenneth Mack at 561-904-3635.

1.0 PROGRAM DESCRIPTION Regulatory Limits L-2022-023 Enclosure The Offsite Dose Calculation Manual (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 mrem/yr to the whole body and less than or equal to 3000 mrem/yrto 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:

a. During any calendar qua1ter: Less than or equal to 5 mrad for gamma radiation and less than or equal to 10 mrad for beta radiation, and

b. During any calendar year: Less than or equal to 10 mrad for gamma radiation and less than or equal to 20 mrad for beta radiation.

Iodine-131, Iodine-133, Tritium, Carbon-14, and Radioactive Material in Particulate Form The dose rate due to Iodine-131 (I-131), Iodine-133 (I-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 I-131, I-133, Tritium, Carbon-14 (C-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:

a. During any calendar quarter: Less than or equal to 7.5 mrem to any organ, and

b. During any calendar year: Less than or equal to 15 mrem to any organ.

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, Column2 for radionuclides other than dissolved or entrained noble gases. For dissolved or entrained noble gases, the concentration shall be limited to 2.0E-4 µCi/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 to:

a. During any calendar quaiter: Less than or equal to 1.5 mrem to the whole body and less than or equal to 5 mrem to any organ, and

b. During any calendar year: Less than or equal to 3 mrem to the whole body and less than or equal to 10 mrem to any organ.

Total Dose L-2022-023 Enclosure 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 mrem to the whole body or any organ, exceptthe thyroid which shall be limited to less than or equal to 75 mrem.

Effluent Concentration Limits Gaseous Effluents For gaseous effluents, effluent concentration limits (ECL) va 1 u es 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 CFRPart20, Appendix B, Table 2, Column 2 are used as the ECL for liquid radioactive effluents released to unrestricted areas. A value of 2.0E-04 µCi/ml is used as the ECL for dissolved and entrained noble gases in liquid effluents.

Measurements and Approximations ofTotalRadioactivity 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 4.0.4 of the ODCM.

The estimate of errors associated with values rep01ted are below:

Error Topic Release Point Mixing Sampling Sample Preparation Sample Analysis Release Volume Total%

The predictability of error for radioactive releases can only be applied to nuclides that are predominant in sample spectrnms. Nuclides that are 1 near background relative to the predominant nuclides in a given sample

. could easily have errors greater than the maximums listed above.

Liquid Radioactive Effluents L-2022-023 Enclosure 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 Strontium-89 (Sr-89), Strontium-90 (Sr-90), Iron-55 (Fe-55),

Nickel-63 (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 reactor 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 continua usly sampled using radioiodine absorbers and particulate filters. The radioiodine absorbers and particulate filters were analyzed weekly for gamma emitting radionuclides using gamma spectroscopy. Results of the noble gas and tritium grab samples, radio iodine absorber, and particulate filter analyses from the current week along with the average effluent flow rate for the previous week were used to determine the total amount of radioactivity released in the continuous mode. The particulate filters were analyzed weekly 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 Contra 1 3.11.2.6.b., a summary of hourly meteorological data collected during 2021 is retained onsite.

This data is available for review by the NRC upon request. During 2 021, the goal of 90% joint data recovery was met. Actual meteorological data

L-2022-023 Enclosure collected during the year was used for the offsite dose calculations in this report.

Carbon-14 Dose Estimation The estimate of 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 the PWR Section, Page 4-28 of the report, and employed the proxy generation rate values for a Combustion Engineering reactor.

The actual 2021 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 2021 from Unit 1 was 10.20 Ci, and the total amount of C-14 released in 2021 from Unit 2 was 10.32 Ci.

Per Regulatory Guide 1.21, Rev 2, Section 5.7, "Real exposure pathways are identified for routine discharges and direct radiation based on the results of the Land Use Census. Dose calculations should typically be performed based on real exposure pathways". Because the 2021 Land Use Census did not identify any land within 5 miles of Site that met the criteria of a garden per Technical Specification 3.12.2 listed in the ODCM, the highest dose exposure pathway from C-14 was calculated from the collection of citrus frnit at an orchard at a distance of 5 miles in the West sector. A "Child" consuming citrns produced at the orchard located 5 miles in the West direction from Site would have received a total combined "Bone Dose" of 5.68E-2 mrem attributed to C-14.

Assessment of radiation dose from radioactive effluents to a MEMBER OF THE PUBLIC due to activities inside the Site boundaiy assumes the visitor to be a Lifeguard at Walton Rocks Beach Recreation Area, located 1 mile southeast of the site. Dose to the visitor on Site for calendar year 2021 was calculated to be 4.75E-09 mrem Total Body dose. See Section 3.4, Dose Assessments, for more detail.

Radiation dose from radioactive effluents to a MEMBER OF THE PUBLIC due to activities inside the Site boundaty is a :fraction of the 1 mrem annual whole-body dose received by the average US citizen from natural occutTing C-14, primarily generated through cosmogenesis in the te11'estrial biosphere (

Reference:

National Council of Radiation Protection Report 45, Natural Background Radiation in the United States).

All C-14 dose calculations are based on Regulatmy Guide 1.109 values.

2.0 SUPPLEMENTAL INFORMATION 2.1 Abnormal Releases or Abnormal Discharges L-2022-023 Enclosure No abnormal (unplanned) releases or discharges occurred during the report period.

2.2 Non-Routine Planned Discharges No non-routine planned discharges occmTed during the report period.

2.3 Radioactive Waste Treatment System Changes No changes were made to the Radioactive Waste Treatment System during the report period.

2.4 Annual Land Use Census Changes During 2021, no garden greater than 500 ft2 was located within 5 miles of Site. Per Technical Specification 3.12.2 listed in the ODCM, C-200, Page 64, broad leaf vegetation (Brazilian Pepper) sampling was performed at the Site Boundaiy in the 2 sectors (WNW and NW) with the highest predicted D/Qs in lieu of the garden census. Controls for broad leaf vegetation sainpling per ODCM Table 3.12-1, Part 4.b, including collection and analysis of control samples, were followed.

2.5 Effluent Monitoring System Inoperability One effluent radiation monitor was out of service for greater than 30 days during the report period:

RM-45-1, Steam Generator Blowdown Treatment Facility (SGBTF)

Vent Rad Monitor was non-functional and declai*ed out of service on 8/23/2021 due to particulate filter high pressure. As per the Offsite Dose Calculation Manual (ODCM), Table 3.3-13, no actions are requh-ed if SGBTF ventilation is secured. In the event SGBTF ventilation were to be placed in service, ODCM, Table 3.3-13 provides actions required to be performed. SGBTF ventilation fans are cunently off. The SGBTF Rad Monitor is cunently not in service.

2.6 Offsite Dose Calculation Manual Changes No changes were made to the Offsite Dose Calculation Manual during the report period.

2.7 Process Control Program Changes No changes were made to the Process Control Program during the report period.

2.8 Corrections to Previous Reports L-2022-023 Enclosure The 2020 Annual Radioactive Effluent Release Report (L-2021-049) was found to contain an error related to the amount of tritium reported in liquid releases for the third and fourth quaiiers. Further investigation revealed and corrected two additional errors with gaseous release permits being closed on the wrong date, making it appear that the releases were 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months longer (i.e.,

greater) than actual. L-2021-049, Enclosure 1, Table 3.1, Gaseous Effluents and Liquid Effluents, and Table 3.3, Dose Assessments were c011*ected and submitted to the Nuclear Regulat01y Commission in Letter L-2021-225 dated December 14, 2021.

2.9 Other AR 2381903 LOSS OF PRESSURE IN 2C Gas Decay Tank {GDT)

When 2C GDT was placed in service, pressure in the tank dropped from 13 psig to 8 psig. Crew decided to press up the 2C GDT to above 10 psig and swap to the 2A GDT, following a gaseous release of 2A UDT. During the 2A GDT release, 2C GDTpressure d1*opped to 6 psig, when it was then removed from service. 2A GDT was NOT dropping pressure ( once isolated from the release). Per the ODCM, an unplanned release is defined for GDTs as: If a GDT loses greater than 2 psig per 8 hours9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months for 9 consecutive shifts, or 18 psig in 72 hours8.333333e-4 days 0.02 hours 1.190476e-4 weeks 2.7396e-5 months , AND the losses were determined to be to the Reactor Auxiliaiy Building Atmosphere, then you must declare the losses an unplanned release.

In this case, the C GDT lost a total of 9 psig in the span of 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months and was then removed from service, and therefore does not meet the definition of an unplanned release.
