SUMMARY
1.1 Radiological Environmental Monitoring Program The Annual Radiological Environmental Operating Report presents data obtained through analyses of environmental samples collected for Waterford 3 Radiological Environmental Monitoring Program (REMP) for the period January 1 through December 31, 2019. This report fulfills the requirements of Waterford 3 Technical Specification 6.9.1.7.
All required lower limit of detection (LLD) capabilities were achieved in all sample analyses during 2019, as required by Waterford 3s Technical Requirements Manual (TRM) Table 4.12-1. No measurable levels of radiation above baseline levels attributable to Waterford 3's operation were detected in the vicinity of Waterford 3.
The 2019 Radiological Environmental Monitoring Program thus substantiated the adequacy of source control and effluent monitoring at Waterford 3 with no observed impact of plant operations on the environment.
Waterford 3 established the REMP prior to the station becoming operational in 1985 to provide data on background radiation and radioactivity normally present in the area. Waterford 3 has continued to monitor the environment by sampling air, water, sediment, fish and broad leaf, as well as measuring direct radiation. Waterford 3 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 31-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. Waterford 3 personnel compare indicator results with control and preoperational results to assess any impact Waterford 3 operation might have had on the surrounding environment.
In 2019, environmental samples were collected for radiological analysis. The results of indicator locations were compared with control locations and previous studies. It was concluded that no significant relationship exists between Waterford 3 operation and effect on the area around the plant. The review of 2019 data showed radioactivity levels in the environment were undetectable in many locations and near background levels in significant pathways.
1.2 Reporting Levels Waterford 3's review indicates that no samples equaled or exceeded reporting levels for radioactivity concentration in environmental samples, as outlined in Technical Requirements Manual (TRM) Table 3.12 2 when averaged over any calendar quarter, due to Waterford 3 effluents. Therefore, 2019 results did not trigger any radiological monitoring program special reports.
Plant: Waterford 3 Year: 2019 Page 6 of 51 Annual Radiological Environmental Operating Report 1.3 Comparison to State Program Waterford 3 personnel compared REMP data to state monitoring programs as results became available. Historically, the programs used for comparison have included the U.S. Nuclear Regulatory Commission (NRC) Thermoluminescent Dosimeter (TLD)
Direct Radiation Monitoring Network and the Environmental Radiological Laboratory -
Department of Environmental Quality Laboratory Services Division (ERL-DEQLSD).
The NRC TLD Network Program was discontinued in 1998. Historically these results have compared to those from the Waterford 3 REMP. Waterford 3s TLD results continue to remain similar to the historical average and continue to verify that plant operation is not affecting the ambient radiation levels in the environment.
The ERL-DEQLSD and the Waterford 3 REMP entail similar radiological environmental monitoring program requirements. These programs include collecting air samples and splitting or sharing sample media such as water, sediment and fish.
Both programs have obtained similar results over previous years.
1.4 Sample Deviations During 2019, environmental sampling was performed for eight media types addressed in the ODCM and for direct radiation. A total of 472 samples of the 475 scheduled were obtained. Of the scheduled samples, 99% were collected and analyzed in accordance with the requirements specified in the ODCM. Attachment 1 contains the listing of sample deviations and actions taken.
As noted in Comment 2, first quarter REMP Airborne Particulate Composite Filters were not analyzed for Gamma Isotopic within the required surveillance frequency of quarterly from previous analysis, resulting in untimely measurement of potential radioactivity in the environment. Adverse Condition Analysis was performed to determine causal factors, and a number of corrective actions were taken to prevent recurrence, including the establishment of formal processes to track analysis time requirements.
1.5 Program Modifications There were no program modifications during the reporting period.

2.0 INTRODUCTION
2.1 Radiological Environmental Monitoring Program Waterford 3 established the REMP to ensure that plant operating controls properly function to minimize any associated radiation endangerment to human health or the environment. The REMP is designed for:
Analyzing applicable pathways for anticipated types and quantities of radionuclides released into the environment.
Considering the possibility of a buildup of long-lived radionuclides in the environment and identifying physical and biological accumulations that may contribute to human exposures.
Considering the potential radiation exposure to plant and animal life in the environment surrounding Waterford 3.
Correlating levels of radiation and radioactivity in the environment with radioactive releases from station operation.
2.2 Pathways Monitored The airborne, direct radiation, waterborne and ingestion pathways are monitored as required by Waterford 3 TRM Table 3.12-1. 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 2019 sampling results with Section 5.0 providing a summary of results for the monitored exposure pathways.
2.3 Land Use Census Waterford 3 conducts a land use census biennially, as required by Section 3.12.2 of the TRM. The purpose of this census is to identify changes in uses of land within five miles of Waterford 3 that would require modifications to the REMP and the Offsite Dose Calculation Manual (ODCM/TRM). The most important criteria during this census are to determine the location in each sector of the nearest:
- 1) Residence
- 2) Animal milked for human consumption
- 3) Garden of greater than 50 m2 (500 ft2) producing broad leaf vegetation.
Waterford 3 conducts the land use census by:
Field surveys in each meteorological sector out to five miles in order to confirm:
Nearest permanent residence Nearest garden > 50 square meters Nearest beef cow Nearest food product Nearest milking animal Identifying locations on maps, measuring distances to Waterford 3 and recording results on data sheets.
Comparing current census results to previous results.

Plant: Waterford 3 Year: 2019 Page 19 of 51 Annual Radiological Environmental Operating Report 4.0 INTERPRETATION AND TRENDS OF RESULTS 4.1 Air Particulate and Radioiodine Sample Results Samples of airborne particulate and radioiodine were collected at four indicator locations and one control location and analyzed for gross beta radionuclides, Iodine-131 and gamma radionuclides (quarterly air particulate filter composites only).
Waterford 3 did not detect any gamma radionuclides in the quarterly air particulate composites or Iodine-131 in the radioiodine cartridges during the reporting period as has been the case in previous years. Indicator gross beta air particulate results for 2019 were similar to background levels obtained during previous years of the operational REMP and well below preoperational levels as seen below. Results are reported as annual average pCi/m3.
Monitoring Period Result 2009 - 2018 (Minimum Value) 0.018 2019 Average Value 0.017 2009 - 2018 (Maximum Value) 0.026 Preoperational 0.080 In the absence of plant-related gamma radionuclides, gross beta activity is attributed to naturally occurring radionuclides. Table 6, which includes gross beta concentrations and provides 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. Therefore, it can be concluded that the airborne pathway continues to be unaffected by Waterford 3 operations.
Plant: Waterford 3 Year: 2019 Page 20 of 51 Annual Radiological Environmental Operating Report 4.2 Thermoluminescent Dosimetry (TLD) Sample Results Waterford 3 reports measured dose as net exposure (field reading less transit reading) normalized to 92 days and relies on comparison of the thirty indicator locations to the one control as a measure of plant impact. Waterford 3s comparison of the inner ring, outer ring, and special interest area TLD results 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 indicator value of 11.5 millirem (mrem) shown in the TLD radiation dose comparison graph below shows the 2019 concentration is comparable to historic results. Overall, Waterford 3 concluded that the ambient radiation levels are not being affected by plant operations.
The average exposure rates during 2019 are consistent with those from the preoperational program and the previous five years of operation. In particular, the preoperational survey indicates that exposure rates ranged between 11 and 33 mrem/standard quarter with an average of 20 mrem/standard quarter. The range during the previous five years of operation was 9 to 15 mrem/standard quarter with an average exposure rate of 12 mrem/standard quarter.
A comparison of the indicator results to the control results, as seen in Table 6, shows that the average indicator locations are slightly higher than that of the control. As shown in Attachment 2, Tables 11-14, several indicator locations are higher than the control by a few mrem with a maximum difference of six mrem. The differences between indicator locations and the control, and TLD stations grouped by distance from the plant are expected due to a variety of factors not related to Waterford 3 plant operations that can affect background radiation in the vicinity of each TLD station.
Plant: Waterford 3 Year: 2019 Page 21 of 51 Annual Radiological Environmental Operating Report 4.3 Waterborne Sample Results Analytical results for 2019 drinking water/surface water samples were similar to those reported in previous years. Gamma radionuclides, iodine-131 and tritium analytical results for 2019 waterborne samples were below the ODCM-required LLD similar to those reported in previous years. Gross Beta continues to be detected in Waterford 3 drinking water samples consistent with historical results. These results are further explained below.
4.3.1 Surface Water Results Samples were collected from one indicator location and analyzed for gamma radionuclides and tritium. Gamma radionuclides were below detectable limits which is consistent with results seen in previous operational years. Tritium was not detected in any of the quarterly samples. Therefore, the operation of Waterford 3 had no definable impact on this waterborne pathway in 2019.
4.3.2 Drinking/Surface Water Results Drinking water samples also serve as surface water samples for Waterford 3.
Therefore, monthly and quarterly gamma spectroscopy and tritium analyses of drinking water also satisfy the surface water sampling requirement.
Samples were collected from two indicators and one control location.
Drinking/Surface water samples were analyzed for, gamma radionuclides, gross beta, iodine-131, and tritium. Gamma radionuclides, iodine-131, and tritium concentrations were below the LLD limits at the indicator and control locations. Gross beta was detected in both indicator and control locations. The average concentration of the indicator locations is comparable to the 2009 - 2018 operational years and below background preoperational data as shown below. Gross beta results from 2019 are summarized in Table 6. Results are reported as annual average pCi/L.
Monitoring Period Result 2009 - 2018 (Minimum Value) 3.1 2019 Average Value 4.1 2009 - 2018 (Maximum Value) 6.6 Preoperational 7.0 Table 17, which includes gross beta concentrations for 2019, provides a comparison of the indicator and control means. It shows that the waterborne pathway continues to remain at background levels. Waterford 3 personnel have noted no definable trends associated with drinking water results at the indicator location. Therefore, the operation of Waterford 3 had no definable impact on this waterborne pathway in 2019 and levels of radionuclides remain similar to those obtained in previous operational years.
Plant: Waterford 3 Year: 2019 Page 22 of 51 Annual Radiological Environmental Operating Report 4.3.3 Sediment Sample Results Sediment samples were collected from two indicators and one control location in 2019 and analyzed for gamma radionuclides. Gamma radionuclides were below the LLD limits at both indicator and control locations. Waterford 3 operations had no significant impact on the environment or public by this waterborne pathway.
4.4 Ingestion Sample Results 4.4.1 Fish Sample Results Fish samples were collected from two indicator and one control location and analyzed for gamma radionuclides. In 2019, gamma radionuclides were below detectable limits which are consistent with the preoperational monitoring period and operational results. Therefore, based on these measurements, Waterford 3 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 has detected radionuclides prior to 1990 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 2019, broad leaf vegetation samples were collected from two indicator and one control location and analyzed for iodine-131 and gamma radionuclides. The 2019 levels remained undetectable, as has been the case in recent years. Therefore, based on these measurements, Waterford 3 operations had no significant radiological impact upon the environment or public by this ingestion pathway.
4.4.3 Milk Sample Results Milk samples from the indicator location were unavailable for collection during 2019; therefore, broad leaf vegetation sampling was performed as required by TRM 3.12-1.
Results are shown in section 4.4.2. Milk samples were collected from one control location and analyzed for iodine-131 and gamma radionuclides. Cesium-137 was measured at concentrations consistent with the preoperational program as well as operational years 2009-2018 as seen below; concentrations were well below the reporting level required by the TRM. Therefore, Waterford 3 concluded that plant operations had no significant impact on this pathway in 2019. Results are reported as annual average pCi/L.

Waterford 3 Year: 2019 Page 23 of 51 Annual Radiological Environmental Operating Report 4.5 Land Use Census Results The latest land use census was conducted September 17 - September 18, 2018. The nearest residence, garden, beef cow, food product and milk animal in each sector within a five mile radius of the plant was located by visual inspection and verbal inquiry.
The land use census identified several changes. The nearest residence in sector D has changed to 111 Kenner Drive at a distance of 0.9 miles from the plant. The goats located 2.4 miles from the plant in sector E have been removed. Beef cows from sector G 4.6 miles from the plant, sector M 1.2 miles from the plant, and sector N 1.0 miles from the plant were removed. There were no changes in the nearest garden, milk cows, or food products in 2018. Based upon the locations identified in this survey, the locations identified in previous surveys and the locations currently being used to calculate dose commitments from liquid and gaseous effluents released from Waterford 3, no REMP sampling location changes are necessary. Results of the 2018 biennial census are shown in Table 5.

Ten analyses did not meet the specified acceptance criteria for the following reasons and were addressed through the TBE Corrective Action Program.
Note: The Department of Energy (DOE) Mixed Analyte Performance Evaluation Program (MAPEP) samples are created to mimic conditions found at DOE sites which do not resemble typical environmental samples obtained at commercial nuclear power facilities.
- 1.
The ERA April 2019 water Cs-134 result was evaluated as Not Acceptable.
The reported value was 15.2 pCi/L (error 2.82 pCi/L) and the known result was 12.1 pCi/L (acceptance range of 8.39 - 14.4 pCi/L). With the error, the reported result overlaps the acceptable range. This sample was run as the workgroup duplicate on a different detector with a result of 10.7 pCi/L (within acceptable range). (NCR 19-10)
- 2.
The ERA April 2019 water Sr-89 result was evaluated as Not Acceptable. The reported value was 44.9 pCi/L and the known result was 33.3 pCi/L (acceptance range of 24.5 - 40.1 pCi/L). The sample was only counted for 15 minutes instead of 200 minutes. The sample was re-prepped in duplicate and counted for 200 minutes with results of 30.7 +/- 5.37 pCi/L and 33.0 +/- 8.71 pCi/L. This was the 1st high failure for Sr-89 in 5 years. (NCR 19-11)
- 3.
The MAPEP February 2019 soil Sr-90 result was not submitted and therefore evaluated as Not Acceptable. The sample was run in duplicate, with results of
-1.32 +/- 4.09 Bq/kg (<6.87) and -1.030 +/- 3.55 Bq/kg (<5.97). The known result was a false positive test (no significant activity). TBE did not submit a result because it appeared that the results may not be accurate. TBE analyzed a substitute soil Sr-90 sample from another vendor, with a result within the acceptable range. (NCR 19-12)
- 4.
The MAPEP February 2019 water Am-241 result was evaluated as Not Acceptable. The reported value was 0.764 +/- 0.00725 Bq/L with a known result of 0.582 Bq/L (acceptable range 0.407 - 0.757 Bq/L). TBEs result falls within the upper acceptable range with the error. It appeared that a non-radiological interference was added and lead to an increased mass and higher result.
(NCR 19-13)
- 5.
The MAPEP February 2019 vegetation Sr-90 result was evaluated as Not Acceptable. The reported result was -0.1060 +/- 0.0328 Bq/kg and the known result was a false positive test (no significant activity). TBEs result was correct in that there was no activity. MAPEPs evaluation was a statistical failure at 3 standard deviations. (NCR 19-14)

- 6.
The ERA October 2019 water Gross Alpha result was evaluated as Not Acceptable. TBEs reported result was 40.5 +/- 10.3 pCi/L and the known result was 27.6 pCi/L (ratio of TBE to known result at 135%). With the associated error, the result falls within the acceptable range (14.0 - 36.3 pCi/L). The sample was run as the workgroup duplicate on a different detector with a result of 30.8 +/- 9.17 pCi/L (within the acceptable range). This was the first failure for drinking water Gr-A since 2012. (NCR 19-23)
- 7.
The ERA October 2019 water Sr-90 result was evaluated as Not Acceptable.
TBEs reported result was 32.5 +/- 2.12 pCi/L and the known result was 26.5 pCi/L (ratio of TBE to known result at 123%). With the associated error, the result falls within the acceptable range (19.2 - 30.9 pCi/L). The sample was run as the workgroup duplicate on a different detector with a result of 20.0 +/-
1.91 pCi/L (within the acceptable range). Both TBE results are within internal QC limits. A substitute quick response sample was analyzed with an acceptable result of 20.1 pCi/L (known range of 13.2 - 22.1 pCi/L). (NCR 19-
- 24)
- 8.
The MAPEP August 2019 soil Ni-63 result of 436 +/- 22.8 Bq/kg was evaluated as Not Acceptable. The known result was 629 Bq/kg (acceptable range 440 -
818 Bq/kg). With the associated error, the TBE result falls within the lower acceptance range. All associated QC was acceptable. No reason for failure could be found. This is the first failure for soil Ni-63 since 2012. (NCR 19-25).
- 9.
The MAPEP August 2019 water Am-241 result was not reported and therefore evaluated as Not Acceptable. Initial review of the results showed a large peak where Am-241 should be (same as the February, 2019 sample results). It is believed that Th-228 was intentionally added as an interference. The sample was re-prepped and analyzed using a smaller sample aliquot. The unusual large peak (Th-228) was seen again and also this time a smaller peak (Am-241). The result was 436 +/- 22.8 Bq/L (acceptable range 0.365 +/- 0.679 Bq/L).
Th-228 is not a typical nuclide requested by clients, so there is no analytical purpose to take samples through an additional separation step. TBE will pursue using another vendor for Am-241 water cross-checks that more closely reflects actual customer samples. (NCR 19-26)
- 10.
The Analytics September 2019 soil Cr-51 sample was evaluated as Not Acceptable. TBEs reported result of 0.765 +/- 0.135 pCi/g exceeded the upper acceptance range (140% of the known result of 0.547 pCi/g). The TBE result was within the acceptable range (0.63 - 0.90 pCi/g) with the associated error.
The Cr-51 result is very close to TBEs normal detection limit. In order to get a reportable result, the sample must be counted for 15 hours1.736111e-4 days <br />0.00417 hours <br />2.480159e-5 weeks <br />5.7075e-6 months <br /> (10x longer than client samples). There is no client or regulatory requirement for this nuclide and TBE will remove Cr-51 from the reported gamma nuclides going forward.
(NCR 19-27)
The Inter-Laboratory Comparison Program provides evidence of in control counting systems and methods, and that the laboratories are producing accurate and reliable data.
