Annual Radiological 2013 Environmental Operating Report Waterford 3 Steam Electric Station Summary The Annual Radiological Environmental Operating Report presents data obtained through analyses of environmental samples collected for Waterford 3's (W3) Radiological Environmental Monitoring Program (REMP) for the period January 1 through December 31, 2013. This report fulfills the requirements of W3 Technical Specification 6.9.1.7.
During 2013, 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.
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 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. W3 compares indicator results with control, preoperational, and previous years operational results to assess any impact W3 might have on the surrounding environment.
In 2013, 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 2013 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 2013. Therefore, no analysis or planned course of action to alleviate problems was necessary.
1
Annual Radiological 2013 Environmental Operating Report Waterford 3 Steam Electric Station Reporting Levels W3'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 W3 effluents. Therefore, 2013 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 include 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-DEQLSD 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 2013, 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 Iodine-131 and 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 2013.
+ Air Samples The air sample locations 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 Radiological 2013 Environmental Operating Report Waterford 3 Steam Electric Station Missed Samples One TLD located at station N-1 was missing at the time of the first quarter exchange. The phosphors in TLDs located at station A-5 were found to be wet at the time of the exchange. The TLDs, although placed in a desiccator, were found to be damaged. Results from those TLDs are considered suspect and not used in any calculations. TLDs located at stations D-2 and H-8 were missing at the time of the second quarter exchange. TLDs located at station H-8 were missing at the time of the third quarter exchange. TLDs located at stations A-5, D-5, and N-1 were missing at the time of the fourth quarter exchange.
Required Lower Limit of Detection (LLD) Values All LLDs during this reporting period were within the acceptable limits required by the W3 TRM.
Unavailable Results W3 received analytical results in adequate time for inclusion in this report. In addition, W3's review identified no missing results.
Program Modifications No program modifications were made during 2013.

Annual Radiological 2013 Environmental Operating Report Waterford 3 Steam Electric Station 1.0 Introduction 1.1 Radiological Environmental Monitoring Program W3 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 important 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 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 Figures 1-1, 1-2 and 1-3.
Section 2.0 of this report provides a discussion of 2013 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 Radiological 2013 Environmental Operating Report Waterford 3 Steam Electric Station 2.0 Interpretation and Trends of Results 2.1 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). W3 did not detect any gamma radionuclides in the quarterly air particulate composites or Iodine-1 31 in the radioiodine cartridges during the reporting period as has been the case in previous years. Indicator gross beta air particulate results for 2013 were similar to those background levels obtained in previous years of the operational REMP andq well below preoperational levels as seen below. Results are reported as annual average pCi/mi Monitoring Period Result Preoperational 0.080 1983-2012 0.020 2013 0.019 Table 3.1, which includes gross beta concentrations for 2013, 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 2013.
2.2 Thermoluminescent Dosimetry Sample Results The average exposure rates during 2013 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 six 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 from the plant are statistically the same as >5 miles while those 2-5 miles are statistically higher.
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 2013 as previous years of operation as evidenced on Attachment 2, Table 2.2. In addition, Radiological Gaseous Effluents for 2013 were only a small fraction of the limits and are not expected to have any impact on environmental TLD measurements.

Annual Radiological 2013 Environmental Operating Report Waterford 3 Steam Electric Station 2.3 Water Sample Results Analytical results for 2013 drinking/surface water samples were similar to those reported in previous years.
DrinkinglSurface Water Drinking water samples also serve as surface water samples for W3. Therefore, monthly and quarterly gamma spectroscopy and tritium analyses of drinking water also satisfy the surface water sampling requirement.
Composite drinking/surface water samples were collected from two indicators and one control location and analyzed for Iodine-1 31, gamma radionuclides and tritium. Results indicate that all measurements were below the calculated LLDs.
Although gross beta was detected in the drinking/surface water samples, results for the indicator locations were below preoperational years and slightly above previous operational years as seen below. Results are reported as annual average pCi/I.
Monitoring Period Result Preoperational 7.0 1983-2012 4.7 2013 5.1 Table 3.1, which includes gross beta concentrations for 2013, 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 one indicator station is statistically the same as the average activity detected at the control station and one indicator station is statistically higher than the mean for the control location. Results are consistent with historical data stated above. Therefore, W3 concluded that plant operations had no significant impact on this pathway during 2013.
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 2013.
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 2013.

Therefore, W3 concluded that plant operations had no significant impact on this pathway during 2013.
2.7 Broadleaf Vegetation Sample Results Broadleaf vegetation samples were collected from two indicators and one control location and analyzed for Iodine-1 31 and 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 2013.
2.8 Land Use Census Results In compliance with the Waterford 3 0DCM and TRM, the land use census was conducted September 24 - September 26, 2012. 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.
One new residence location (sector R) and four new garden locations (sectors D, G, N, and R) were identified in 2012. Milk cow, goat, beef cow and food product locations remained unchanged for 2012. 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 2012 biennial census are shown in Table 2.1.
2.9 Interlaboratory 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.

Annual Radiological Environmental Operating Report 2013 Waterford 3 Steam Electric Station Statistical Analyses Calculation of the Mean and Standard Deviation The mean and standard deviation for different groups of analyses are calculated using the following equations:
x xi j.=
and 10.5 where:
X = mean of sample population, S = standard deviation of sample population, n = number of samples in sample population, and Xi = value of the i'th sample.
52
Annual Radiological 2013 Environmental Operating Report Waterford 3 Steam Electric Station Comparing Two Sample Population Means The means of two 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 populations 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 calculated from the equation below (obtained from the CRC Standard Mathematical Tables, 26th Edition (1981)):
X-Y nx +n,,-2
)
nx n.,
where:
t
= calculated "t" value, X
= mean of first data set, Y
= mean of second data set, 7, = number of variables in first data set, S, = standard deviation of first data set, q y = number of variables in second data set, and S y = standard deviation of second data set.
The calculated "tr 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 It" value such that:
a if t > t p,n then reject the hypothesis when m, > m Y,
- b.
if t < -t,n then reject the hypothesis when m, < m y,
- c.
if t > t p/2,n then reject the hypothesis when m x = m y, where t p/2,n and t p,n are the tabular "t" values, with a preselected error (5%), confidence level (1 -
p) or (1-p1/2), and degrees of freedom n = nx + ny - 2. Tabular values of the "t" were obtained from the CRC Standard Mathematical Tables, 26th Edition (1981).
