SUMMARY

1.1 Radiological Environmental Monitoring Program The data obtained through the Turkey Point Radiological Environmental Monitoring Program (REMP) verifies that the levels of radiation and concentrations of radioactive materials in environmental samples are not increasing. These measurements verify that the dose or dose commitment to members of the public, due to operation of Turkey Point Units 3 & 4, during the surveillance year, is well within the limits established by 10 CFR 50, Appendix I. The sampling period was from January 1, 2022 to December 31, 2022. Additionally, supplemental samples collected by the State of Florida, Department of Health (DOH), do not indicate adverse trends in the radiological environment.

All required lower limit of detection (LLD) capabilities were achieved in all sample analyses during 2022, as required by the Turkey Point Units 3 & 4 Technical Specifications. No measurable levels of radiation above baseline levels attributable to Turkey Point Nuclear operation were detected in the vicinity of PTN. The 2022 Radiological Environmental Monitoring Program thus substantiated the adequacy of source control and effluent monitoring at Turkey Point Nuclear with no observed impact of plant operations on the environment.

Turkey Point Nuclear established the REMP prior to the stations becoming operational to provide data on background radiation and radioactivity normally present in the area. PTN has continued to monitor the environment by sampling air, water, sediment, crustacea, fish and broadleaf vegetation, as well as measuring direct radiation. PTN also samples milk if milk-producing animals used for human consumption are present within five miles (8 km) of the plant.

The REMP includes sampling indicator and control locations within an approximate 20-mile radius of the plant. The REMP utilizes indicator locations near the site to show any increases or buildup of radioactivity that might occur due to station operation and control locations farther away from the site to indicate the presence of only naturally occurring radioactivity. PTN personnel compare indicator results with control results to assess any impact PTN operation might have had on the surrounding environment.

In 2022, environmental samples were collected for radiological analysis. The results of indicator locations were compared with control locations. It was concluded that no significant relationship exists between PTN operation and effect on the area around the plant. The review of 2022 data showed radioactivity levels in the environment were undetectable in many locations and near background levels in significant pathways.

Radiological environmental monitoring for the Turkey Point Plant is conducted by the State of Florida, DOH. Samples are collected and analyzed by DOH personnel. Samples are analyzed at the DOH Environmental Radiation Control Laboratory in Orlando, Florida. The 2022 Radiological Surveillance Quarterly Report data is provided by the State of Florida Bureau of Radiation Control and is presented in Attachment 2. The State of Florida is not involved in the (Industry Initiative) ground water monitoring program.

2.0 INTRODUCTION

This report is submitted pursuant to Specification 6.9 of Turkey Point Units 3 & 4 Technical Specifications. The Annual Radiological Environmental Operating Report provides information, summaries and analytical results pertaining to the Radiological Environmental Monitoring Program for the calendar year indicated. This report covers surveillance activities described in the Offsite Dose Calculation Manual (ODCM) meeting the requirements of Unit 3 and Unit 4 Technical Specifications.

2.1 Radiological Environmental Monitoring Program The Radiological Environmental Monitoring Program for the Turkey Point Plant is conducted pursuant to Control 5.1 of Turkey Point Unit 3 & 4 ODCM.

A. Purpose The purpose of the Radiological Environmental Monitoring Program is to provide representative measurements of radiation and of radioactive materials in those exposure pathways and for those radionuclides which lead to the highest potential radiation exposures of members of the public resulting from station operation.

The Radiological Environmental Monitoring Program also supplements the radiological effluent monitoring program by verifying that the measurable concentrations of radioactive materials and levels of radiation are not higher than expected on the basis of the effluent measurements and the modeling of the environmental exposure pathways.

Sample Locations, Types and Frequencies:

Direct radiation gamma exposure rate is monitored continuously at 23 locations by thermoluminescent dosimeters (TLDs). TLDs are collected and analyzed quarterly.

Airborne radioiodine and particulate samplers are operated continuously at six locations. Samples are collected and analyzed weekly. Analyses include Iodine-131, gross beta, and gamma isotopic measurements.

Surface water samples are collected from three locations. Samples are collected and analyzed monthly. Analyses include gamma isotopic and tritium measurements.

Shoreline sediment samples are collected from three locations coinciding with the locations for surface water samples. Samples are collected and analyzed semi-annually. Sediment samples are analyzed by gamma isotopic measurements.

Fish and invertebrate samples are collected from two locations coinciding with two of the locations for surface water samples. Samples are collected and analyzed semi-annually. Fish and invertebrate samples are analyzed by gamma isotopic measurements.

Broad leaf vegetation samples are collected from three locations. Samples are collected and analyzed monthly. Broad leaf vegetation samples are analyzed by gamma isotopic measurements.

Note: Ground Water Protection, NEI Initiative: The program and results are described in Attachment 4.

2.2 Pathways Monitored The airborne, direct radiation, waterborne and ingestion pathways are monitored as required by Control 5.1 of Turkey Point Unit 3 & 4 ODCM. A description of the REMP utilized to monitor the exposure pathways is described in the attached Tables and Figures.

Section 4.0 of this report provides a discussion of 2022 sampling results with Section 5.0 providing a summary of results for the monitored exposure pathways.

2.3 Land Use Census PTN conducts a land use census, as required by Turkey Point Units 3 & 4 ODCM.

The purpose of this census is to identify changes in uses of land within five miles of PTN that would require modifications to the REMP and the Offsite Dose Calculation Manual (ODCM). Section 4.5 on the report contains a narrative on the results of the 2022 land use census.

Plant: Turkey Point Nuclear Units 3 & 4 Year: 2022 Page 16 of 56 Annual Radiological Environmental Operating Report 4.0 INTERPRETATION AND TRENDS OF RESULTS 4.1 Air Particulate and Radioiodine Sample Results In 2022 there were no samples above the LLD for I-131. Indicator gross beta air particulate results for 2022 were comparable to results obtained from 2019-2021 of the operational REMP. Results are reported in picocuries per cubic meter (pCi/m3).

Monitoring Period Result 2019 - 2021 (Minimum Value) 0.002 2022 Average Value 0.013 2019 - 2021 (Maximum Value) 0.030 Gross beta activity is attributed to naturally occurring radionuclides. Table 6, which include gross beta concentrations and provide a comparison of the indicator and control means and ranges emphasizes the consistent trends seen in this pathway to support the presence of naturally occurring activity. Figure 3 is a comparison of the weekly Gross Beta results for 2022.Therefore, it can be concluded that the airborne pathway continues to be unaffected by Turkey Point Nuclear operations.

Plant: Turkey Point Nuclear Units 3 & 4 Year: 2022 Page 17 of 56 Annual Radiological Environmental Operating Report 4.2 Thermoluminescent Dosimetry (TLD) Sample Results Turkey Point Nuclear reports relies on comparison of the indicator locations to the control as a measure of plant impact. Turkey Point Nuclears comparison of the indicator to the control, as seen in Table 6, identified no noticeable trend that would indicate that the ambient radiation levels are being affected by plant operations. In addition, the quarterly indicator averages shown in the TLD radiation dose comparison graph below shows the 2022 indicator results are comparable to control location results. Overall, Turkey Point Nuclear concluded that the ambient radiation levels are not being affected by plant operations.

4.3 Waterborne Sample Results Analytical results for 2022 surface water samples were similar to those reported in previous years. Gamma radionuclides and tritium analytical results for 2022 waterborne samples were below the ODCM-required LLD similar to those reported in previous years. These results are further explained below.

4.3.1 Surface Water Results Samples were collected from two indicator and one control location and analyzed for gamma radionuclides and tritium. Tritium was detected in 1 out of 24 indicator location samples with a concentration of 84 pCi/L which is consistent with results seen in previous operational years. There were no plant related gamma radionuclides detected in any of the control or indicator location samples. Therefore, the operation of Turkey Point Nuclear had no definable impact on this waterborne pathway during 2022.

Plant: Turkey Point Nuclear Units 3 & 4 Year: 2022 Page 18 of 56 Annual Radiological Environmental Operating Report 4.3.2 Shoreline Sediment Sample Results Sediment samples were collected from two indicators and one control location in 2022 and analyzed for gamma radionuclides. Plant related gamma radionuclides were below the LLD limits at both indicator and control locations. Turkey Point Nuclear operations had no significant impact on the environment or public by this waterborne pathway.

4.4 Ingestion Sample Results 4.4.1 Crustacea and Fish Sample Results Crustacea and Fish samples were collected from one indicator and one control location and analyzed for gamma radionuclides. In 2022, gamma radionuclides were below detectable limits which are consistent with the results seen in previously operational years. Therefore, based on these measurements, Turkey Point Nuclear operations had no significant radiological impact upon the environment or public by this ingestion pathway.

4.4.2 Broad Leaf Vegetation Sample Results The REMP had detected radionuclides prior to 1990 in vegetation that are attributable to other sources. These include the radioactive plume release due to reactor core degradation at Chernobyl Nuclear Power Plant in 1986 and atmospheric weapons testing.

In 2022, Broad Leaf Vegetation samples were collected from two indicator and one control locations and analyzed for gamma radionuclides. The 2022 Cs-137 was detected in samples collected from the indicator and control locations. This activity identified could be from weapons fallout testing 30-40 years ago and reactor accidents at Chernobyl and are contributors. Therefore, based on these measurements, Turkey Point Nuclear operations had no significant radiological impact upon the environment or public by this ingestion pathway.

4.5 Land Use Census Results The latest land use census (performed in 2022) did not identify any new locations that yielded a calculated dose or dose commitment greater than those currently calculated (see Table 5).

The land use census identified no changes in the new resident census.

There were no changes in the milk cows/goats or garden census in 2022.

Plant: Turkey Point Nuclear Units 3 & 4 Year: 2022 Page 48 of 56 Annual Radiological Environmental Operating Report Page 1 of 3 Interlaboratory Comparison Program Results 1.0 Summary The Interlaboratory Comparison Program consists of participating in the DOE Mixed Analyte Performance Evaluation Program (MAPEP).

This program provides similar testing (matrices, nuclides, and levels) as the former EPA Interlaboratory Comparison Program and is referred to as the Mixed Analyte Performance Evaluation Program (MAPEP).

The samples are analyzed using the methods applicable to the REMP (gamma spectroscopy, Gross Beta, and Tritium for water).

From the MAPEP handbook:

Acceptance criteria were developed from a review of precision and accuracy data compiled by other performance evaluation programs (PEPs), the analytical methods literature, from several MAPEP pilot studies, and from what is considered reasonable, acceptable, and achievable for routine analyses among the more experienced laboratories.

The State laboratory participated in MAPEP 46 and 47. These satisfied the requirement of Control 5.3 of the ODCM for the Interlaboratory Comparison Program.

Sensitivity Evaluation has no acceptance range but an identified value at low activity.

Plant: Turkey Point Nuclear Units 3 & 4 Year: 2022 Page 51 of 56 Annual Radiological Environmental Operating Report Page 1 of 4 Industry Initiative Ground Water Protection Program 2022 1.0 Description of Program Turkey Point Nuclear maintains a sampling and analysis program to meet procedural requirements.

The procedures that govern the performance are EV-AA-100-1001, Fleet Ground Water Protection Program Implementing Guideline and 0-ADM-654, Ground Water Protection Program.

The sampling frequency is quarterly; more often if conditions warrant.

Sample assay is performed by a private contractor GEL labs.

2.0 Discussion The Turkey Point Nuclear site is surrounded on three sides by the closed cooling canal system.

This canal system, in addition to being the source of tertiary cooling, is the body of water receiving permitted liquid radiological waste the canal system tritium level averages was 5,005 pCi/L in 2022 with a max concentration of 11,679 pCi/L. This supports the expectation to see tritium in subsurface water collected either on-site or off-site close to the (within the Owner Controlled Area) cooling canal system. Twenty-eight (28) wells were involved in the 2022 monitoring program; some locations have multiple (two or three) depths.

Samples are analyzed for Tritium & Gamma emitters. As conditions warrant, analysis included Fe-55, Ni-63, Sr-89/90 and alpha (all were < LLD).

3.0 Results The tritium results for the groundwater wells were from <MDA to 3,980 pCi/L. All results were less than the limits of the Offsite Dose Calculation Manual, Table 5.1-2, Reporting Levels for Radioactivity Concentrations in Environmental Samples. Storm drain outfalls occasionally are below the tidal mark of the canal and will have ingress of canal water into the storm drain. The higher levels of tritium in the storm drain section are due to the canal water ingress into the storm drain.
