Armua! Radiofogical 2616 Environmental Operating Report Waterford 3 Steam El'ectric Station Summary The Annual Radiotogk:aI Environmental Operating Report presents data obtained through analyses of environmental samp[es collected for Waterford 3"s {W3) Radiological Environmental Monitoring Program

{REMP} for the period January 1 through December 31. 2016. This report fulfills the requirements of W3 Technical Specification 6.9.1.7.

During 2016, gross beta radioactivity was detected in air and drinking/surface water locations. Results obtained at the indicator locations were similar to those obtained at the control location. Therefore, levels continue to remain at background.

Cesium-137 was detected during 2016 at control milk location MKA-31. This is consistent with results obtained from the preoperational program and previous years of operation. The level of Cesium-137 in the sample was below the reporting level required by the W3 TRM.

Radiological Environmental Monitoring Program W3 established the REMP prior to the station becoming operational {1985) to provide data on background radiation and radioactivity normally present in the area. W3 has continued to monitor the environment by sampling air, water, sediment, milk, fish and broad leaf vegetation, as well as measuring radiation directly.

The REMP includes sampling indicator and control locations within a 31-mile radius of the plant. The REMP utilizes indieator 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. W3 compares indicator results with control, preoperational, and previous years operational results to assess any impact W3 might have on the surrounding environment.

In 2016, W3 collected environmental samples for radiological analysis. Based on the comparison results of indicator locations with control locations and previous studies, it was concluded that overall W3 operations had no significant impact on plant environs. The review of 2016 data, in many cases, showed undetectable radiation levels in the environment and near background levels in significant pathways associated with W3.

Harmful Effects or Irreversible Damage The REMP did not detect any harmful effects or evidence of irreversible damage in 2016. Therefore, no analysis or planned course of action to alleviate problems was necessary.

• ---------~----------------~-------*

Annuaf Radiorogfcal 2016 EnvironmerrtaE Operating Report Waterfocd 3 Steam Beciric station:

Reporting' levels W?ks review indicates. that no samp[es equated or exceeded reporting levels for radioactivity concentration in environmental samp[es, as outfined in Technical Requirements Manual {TRM}

Table 3.12-2 when averaged over any calendar quarter. due to W3 effluents_ Therefore. 2016 results did not trigger any radiological monitoring program special reports.

Radioactivity Not Attributable to W3 The W3 REMP detected radioactivity attributable to other sources three times. These incfude the 25th Chinese nuclear test explosion in 1980, the radioactivity plume release due to reactor core degradation at the Chernobyl Nuclear Power Plant in 1986, and the airborne release from Dai-ichi, Fukushima following the Tohoku earthquake on March 11, 2011.

Comparison to State Program W3 compared REMP data to the monitoring program of the Environmental Radiological Laboratory-Department of Environmental Quality Laboratory Services Division (ERL-DEQLSD}. The ERL-OEQLSD and the W3 REMP entail similar radiological environmental monitoring program requirements. Both programs have obtained similar results over previous years.

Sample Deviations

• Milk Samples Since milk samples for indicator location MKE-3 were unavailable for all quarters of 2016, broad leaf vegetation sampling was performed as required by TRM Table 3.12-1. Broad leaf vegetation results are in section 2. 7. Milk samples were collected from one control location and analyzed for lodine-131 and gamma radionuclides. Results for lodine-131 indicate that all measurements were below the calculated LLDs. Cesium-137 was detected during 2016 at control milk location MKA-31. This is consistent with results obtained from the preoperational program and previous years of operation.

The level of Cesium-137 in the sample was below the reporting level required by the W3 TRM.

Therefore, W3 concluded that plant operations had no significant impact on this pathway during 2016.

• Air Samples The air sample location listed below failed to meet the requirement for sample continuity. As described in footnote (1) of TRM Table 3.12-1, deviations are permitted from the required sampling schedule due to malfunction of sampling equipment and other legitimate reasons.

Annual Radio£agican 2016 Environmentar Operating Report Waterfmrl 3 Steam Becirlc Station 1.0 Introduction 1.1 Radiological Environmental Monitoring Program W3 established the REMP to ensure that plant operating controls properly function fo minimize any associated radiation endangerment to human health or the environment The REMP £s designed for:

• Analyzing important pathways for anticipated types and quantities of radianuciides released into the environment

• Considering the possibility of a buildup of long-Hved radionuclides in the environment and identifying physical and biological accumulations that may contribute fo human exposures.

• Considering the potential radiation exposure to plant and animal life in the environment surrounding W3.

• Correlating levels of radiation and radioactivity in the environment with radioactive releases from station operation.

1.2 Pathways Monitored The airborne, direct radiation, waterborne and ingestion pathways are monitored as required by W3 TRM Table 3.12-1. A description of the W3 REMP utilized to monitor the exposure pathways is described in Table 1.1 and shown in Rgures 1-1, 1-2 and 1-3.

Section 2.0 of this report provides a discussion of 2016 sampling results with Section 3.0 providing a summary of results for the monitored exposure pathways.

1.3 Land Use Census W3 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 W3 that would require modifications to the REMP and the Offsite Dose Calculation Manual (ODCM). 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 2 2

3) Garden of greater than 50 m (500 ft ) producing broad leaf vegetation.

W3 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 and approximate size

}> Nearest beef cow

};> Nearest food product

}> Nearest milking animal

• Identifying locations on maps, measuring distances to W3 and recording results on data sheets.

• Comparing current census results to previous results.

Annual Radfafogicall 2.016 Environmernan Operating Report Waterford 3 Steam Efecfrlc Station:

2.0 mterpretafion and Trends of Results 2.1 Air Particulate and Radioiodine Sample Results Samp!es of airborne particulate and radioiodine were co((ected at four indfcator locations and one control location and analyzed for gross beta radionuclides, lodine-131 and gamma radionuc!fdes (quarterly air particulate filter composites only). W3 did not detect any gamma radionuclides in fue quarterly air particulate composites or fodine-131 in the radio1odine cartridges during the reporting period as has been fue case in previous years. Indicator gross beta air particulate results for 2016 were similar to those background levels obtained ln previous years offue operational REMP and well below preoperational levels as seen below. Results are reported as a '

annual average pCiJm .

Monitoring Period Result Preoperational 0.080 1983-2015 0.020 2016 0.019 Table 3.1, which includes gross beta concentrations for 2016, provides a comparison of the indicator and control means. It further emphasizes that the airborne pathway continues to remain at background levels. In addition, as shown in Attachment 2, the standard "t" test was used to compare average gross beta activity from each indicator station to the average gross beta activity at the control station. The results from this test show the average activity detected at all indicator stations is statistically the same as the average activity detected at the control station. Therefore, W3 concluded that plant operations had no significant impact on this pathway during 2016.

2.2 Thermoluminescent Dosimetry Sample Results The average exposure rates during 2016 are consistent with those from the preoperational program and the previous five years of operation as seen in Figure 2-1. 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 8 to 16 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 3.1, shows that the average indicator is slightly higher than that of the control. As shown in Attachment 1, Table 2.1, several indicator locations are higher than the control by a few mrem with a maximum difference of five mrem.

As shown in Attachment 2, Table 2.1, the standard "t" test was used to compare average exposure rates for TLD stations located in groups 0-2 miles and 2-5 miles from the plant to those

> 5 miles. The results indicate that the average exposure rates 0-2 miles and 2-5 miles from the plant are statistically the same as >5 miles.

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 W3 plant operations that can affect background radiation in the vicinity of each TLD station. Direct radiation measurements at each TLD station have remained statistically the same in 2016 as previous years of operation as evidenced on Attachment 2, Table 2.2. In addition, Radiological Gaseous Effluents for 2016 were only a small fraction of the limits and are not expected to have any impact on environmental TLD measurements.

Annual Radiofogfcaf1 2Qi1i6 Environmental Operating Report Waterford 3 Steam Beefric Stattolill 2.3 Water Sample Results Analytical results for 2016 drinkingfswface water samp[es were sfmifar to those reported: in previous years.

Drinking/Surface Water Drinking water samples a!so serve as surface vmter samples for W3. Therefore. monthly and quarterly gamma spectroscopy and fnlium analyses of drinking water also satisfy the surface water sampling requirement.

Composite drinkinglsurface water sampfes were collected from two indicators and one control location and analyzed for lodine-131, gamma radionuclides and tritium. Results indicate that all measurements were below the calculated LLDs.

Although gross beta was detected in the drinkinglsurface water samples, results for the indicator locations were below previous operational and preoperational years as seen below. Results are reported as annual average pCiJI.

Monitoring Period Result Preoperational 7.0 1983-2015 4.7 2016 4.4 Table 3.1, which includes gross beta concentrations for 2016, provides a comparison of the indicator and control means. It shows that the waterborne pathway continues to remain at background levels. In addition, as shown in Attachment 2, the standard "t" test was used to compare average gross beta activity from indicator stations to the average gross beta activity from the control station. The results from the test show the average activity detected at each indicator station is statistically the same as the average activity detected at the control station.

Therefore, W3 concluded that plant operations had no significant impact on this pathway during 2016.

Surface Water Surface water samples were collected from one indicator location and analyzed for gamma radionuclides and tritium. Results indicate that all measurements were below the calculated LLDs. Therefore, W3 concluded that plant operations had no significant impact on this pathway during 2016.

2.4 Sediment Sample Results Sediment samples were collected from two indicator locations and one control location and analyzed for gamma radionuclides. Results indicate that all measurements were below the calculated LLDs. Therefore, W3 concluded that plant operations had no significant impact on this pathway during 2016.

AmruaJ Ra.diatogrcat 201!6 Environmental Operatirig Report Waferford. 3 Steam E!ecmc Sfafioirn 2..5 Milk Sample Results Since milk samples for indicator location MKE-3 were unavailable far aH quarters of 2016, broad

[eaf vegefanon sampling was performed as required by TRM Table 3.12-1. Broad leaf vegetation results are in section 2.7. Milk samples were coUected from one control (ocation and analyzed for lodine-131 and gamma radionuclides. Resu[ts for locfine-131 indicate that all measurements were below the calculated LLDs. Cesium-137 was detected during 2016 at control milk rocation MKA-31. This fs consistent with results obtained from the preoperational program and previous years of operation. The level of Cesium-137 in the sample was below the reporting level required by the W3 TRM. Therefore, W3 concluded that plant operations had no significant impact on this pathway during 2016.

2.6 Fish Sample Results Fish samples were collected from two indicators and one control location and analyzed for gamma radionuclides. Results indicate that all measurements *were below the calculated LLDs.

Therefore, W3 concluded that plant operations had no significant impact on this pathway during 2016.

2.7 Broadleaf Vegetation Sample Results Broadleaf vegetation samples were collected from two indicators and one control location and analyzed for lodine-131 and gamma radionuclides. Results indicate that an measurements were below the calculated LLDs. Therefore, W3 concluded that plant operations had no significant impact on this pathway during 2016.

2.8 Land Use Census Results In compliance with the Waterford 3 ODCM and TRM, the land use census was conducted September 19 - September 21, 2016. 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.

Four new garden locations (sectors A, C, D, and Q), one new resident location (sector P), two new goat locations (sectors A and E), and two new beef cow locations (sectors B and E) were identified in 2016. Food product and milk cow locations remained unchanged for 2016. 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 W3, no REMP sampling location changes are necessary. Results of the 2016 biennial census are shown in Table 2.1.

2.9 lnterlaboratory Comparison Results Teledyne Brown Engineering, Inc. analyzed interlaboratory comparison samples for W3 to fulfill the requirements of Section 5.7.2 of the ODCM. Attachment 1 contains these results.

• Calculation of the Mean and Standard Deviation The mean and standard deviation for cflfferent groups of analyses are ca!cu!ated using the following equations:

X=:tX; jv[ n and t;" (X; - Xj ]0.5 S=

[ (n-1) where:

X =mean of sample population, S =standard deviation of sample population, n = number of samples in sample population, and

X; value of the i'th sample.

+ Comparing Two Sample Popuration Means The means of tw'o* sample populations are compared for statistical difference using the standard "t" test The use of the test requires the assumption that the data within the popufations are normally distributed and that the true standard deviations of the mean are equal for both populations_ The standard "t" test tests the hypothesis that the true means of both populations are equal. The "t" value can be cafculated from the equation below {obtained from the CRC Standard Mathematical Tables.

26th Edition {1981)):

X-Y t

where:

t = calculated "t" value, X = mean of first data set.

Y = mean of second data set, 1/" = number of variables in first data set, S x = standard deviation of first data set, 1/ y = number of variables in second data set, and S y = standard deviation of second data set.

The calculated "t" value is used to test the hypothesis that the true mean of the first population (m x) is equal to the true mean of the second population (m y) assuming that the true standard deviation of both populations are equal (m x =m y). The calculated "t" value is compared to a tabular "t" value such that:

a if t > t 11 .n then reject the hypothesis when m x > m Y*

b. if t < -t 11, 0 then reject the hypothesis when m x < m Y*

c. if t > t IJ/2,n then reject the hypothesis when m x =m Y*

where t IJ/2,n and t 11 .n are the tabular "t" values, with a preselected error (5%), confidence level (1 -

µ)or

=

(1- µ/2), and degrees of freedom n nx + ny- 2. Tabular values of the "t" were obtained from the CRC Standard Mathematical Tables, 26th Edition (1981).
