T he Annual Radiolog ical Environmental Operating Report provides information, summaries and analytical results pertaining to the Radiolog ical Environmental Monitoring Program for the calendar year indicated. Th is report covers surveil lance activities described in the Offsite Dose Calculation Manual (O DCM) meeting the requirements of Unit 3 and Unit 4 Technical Specifications.

II. RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM A Pu rpose The purpose of the Radiolog ical Environmental Monitoring Program is to provide representative measurements of radiation and of radioactive materials in those exposure pathways and for those radionucl ides which lead to the highest potential radiation exposures of members of the publ ic resu lting from station operation. T he Radiological Environme ntal Monitoring Program also supplements the rad iological 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.

b. Airborne radioiodine and particulate samplers are operated continuously at six locations.

Samples are collected and analyzed weekly. Analyses include lodine-131 , gross beta, and gamma isotopic measurements.

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

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

e. 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.

f. 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.

Attachment A provides specific information pertaining to sample locations, types and frequencies.

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

2. Analytical Responsibility:

Radiological environmental monitoring for the Turkey Point Plant is conducted by the State of Florida, Department of Health (DOH). Samples are collected and analyzed by DOH personnel.

Samples are analyzed at the DOH Environmental Radiation Control Laboratory in Orlando, Florida.

Note: The State is not involved in the (Industry Initiative) ground water monitoring program .

C. Analytical Resu lts Table 1, Environmental Radiological Monitoring Program Annual Summary provides a summary for all specified samples collected during the referenced surveillance period. Deviations from the sample schedule, missing data and/or samples not meeting the specified "A PRIORI" LLD, if any, are noted and explained in Tables 1A and 1B respectively. Analysis data for all specified samples analyzed during the surveillance period is provided in Attachment B.

2017 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT TURKEY POINT PLANT- UNITS 3 & 4 D. Land Use Census A land use census out to a distance of 5 miles radius from the Turkey Point Plant is conducted annually to determine the location of the nearest milk animal, residence , and garden producing broad leaf vegetation , in each of the sixteen meteorological sectors. A summary of the land use census for the surveillance year is provided in Table 2, Land Use Census Summary.

E. lnterlaboratory Comparison Program The lnterlaboratory 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 lnterlaboratory 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 results for nuclides associated with the REMP are listed in ATIACHMENT C, Results from the lnterlaboratory Compan'son Program.

2017 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT TURKEY POINT PLANT- UNITS 3 & 4 Ill. DISCUSSION AND INTERPRETATION OF RESULTS A. Reporting of Results The Annual Radiological Environmental Operating Report contains the summaries, interpretations and information required by Control 1.4 of ODCM. Table 1 provides a summary of the measurements made for the nuclides required by ODCM Table 5.1-2, for all samples specified by Table 5.1-1 . In addition , summaries are provided for other nuclides identified in the specified samples, including those not related to station operation. These include nuclides such as K-40 , Th-232, Ra-226, and Be-7 which are common in the Florida environment.

B. Interpretation of Results

1. Direct Radiation :

The results of direct radiation monitoring are consistent with past measurements for the specified locations. The exposure rate data shows no indication of any trends attributed to effluents from the plant. The measured exposure rates are consistent with past historical exposure rates.

2. Air Particulates/Radioiodine:

For results attributed to plant effluents:

The results for radioactive air particulate and radioiodine monitoring are consistent with past measurements and indicate no trends attributed to plant effluents. All samples for radioiodine yielded no detectable 1-131 . Gamma isotopic measurements yielded no indication of any nuclides attributed to station operation. The results for air particulate/radioiodine samples are consistent with historical trends. Air particulate and radioiodine monitoring results are summarized in Table 1.

3. Waterborne , Surface Water:

The results of radioactivity measurements in surface water samples are consistent with past measurements. Tritium was reported as present in 2 of 24 indicator locations and O of the 12 control locations. The highest reported tritium is 128 pCi/L, below the required reporting level of 30,000 pCi/L as specified by ODCM Table 5.1-2. Additionally, the highest reported tritium for the supplemental sampling program is 24,483 pCi/L.

4. Waterborne, Sediment:

Gamma isotopic measurements yielded no indication of any nuclides attributed to station operation.

5. Waterborne, Food Products:

The results are consistent with past measurements. Gamma isotopic measurements yielded no indication of any nuclides attributed to station operation.

6. Broad Leaf Vegetation For results attributed to plant effluents:

The results of radioactivity measurements are consistent with past measurements. Cs-137 was detected in samples collected from the indicator locations. This activity identified could be from weapons fallout testing 30-40 years ago and reactor accidents at Chernobyl and are contributors . The maximum concentration reported was 97 pCi/kg well below the Page 7 of 96

__J

2017 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT TURKEY POINT PLANT- UNITS 3 & 4 requ ired reporting level of 2000 pCi/kg as specified by ODCM Table 5.1-2. No other fission products were detected.

7. Land Use Census A land use census out to a distance of a five mile radius from the Turkey Point Plant is conducted annually to determine the location of the nearest milk animal , residence, and garden producing broad leaf vegetation , in each of the 16 meteorological sectors. A summary of the land use census for the survei llance year is provided in Table 2, Land Use Census Summary.

8. lnterlaboratory Comparison Program The State laboratory participated in MAPEP 36 and 37. These satisfied the requirement of Control 5.3 of the ODCM for the lnterlaboratory Comparison Program . The results are listed in Attachment C.

C. Conclusions The data obtained through the Turkey Point Plant Radiological Environmental Monitoring Program verifies that the levels of radiation and concentrations of radioactive materials in environmental samples, representing the highest potential exposure pathways to members of the public, are not being increased . The measured exposure rates and air particulate/radioiodine samples are consistent with exposure rates that were observed during the pre-operational surveillance program .

The highest value of tritium in surface water was 128 pCi/L far below the required LLD listed in ODCM Table 5.1-3. There were no indications of any other nuclides that could be attributed to plant effluents. There were no indications of any nuclides in waterborne sediment or food products attributed to plant effluents. The results of radioactivity measurements for broad leaf vegetation are consistent with past measurements. Additionally, supplemental to the ODCM program , sampling of the direct exposure, inhalation, and ingestion pathways, performed by Florida DOH , does not show adverse trends in levels of radiation and radioactive materials in unrestricted areas. The 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, are well within "as low as reasonably achievable (ALARA)" criteria established by 10 CFR 50, Append ix I.

NOTES

a. The LLD is an "a priori" lower limit of detection which establishes the smallest concentration of radioactive material in a sample that will yield a net count above system background that will be detected with 95% probability with only 5% probability of falsely concluding that a blank observation represents a real signal.LLDs in this column are at time of measurement. The MDAs reported in Attachment B for the individual samples have been corrected to the time of sample collection .

b. Mean and range based upon detectable measurements only. Fraction of detectable measurements at specified locations is indicated in parentheses (f).

c. Specific identifying information for each sample location is provided in Attachment A.

d. Results were based upon the average net response of three elements in a TLD. (Thermoluminescent Dosimeter) .

ATTACHMENT D Industry Initiative Ground Water Protection Program Tritium in Ground Water Monitoring 2017 Page 92 of 96

A. Description of Program:

Turkey Point maintains a sampling and analysis program to meet the requirements of NEI 07-07, Industry Ground Water Protection Initiative. The procedures that govern the performance are EV-AA-100-1001 , Fleet Ground Water Protection Program Implementing Guideline and O-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.

B. 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 10,391 pCi/L in 2017 with a max concentration of 24,483 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 2017 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).

C. Results The tritium results for the groundwater wells were from <MDA to 13600 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.

Tabular results follow:
