Annual Radiological 2014Environmental Operating Report Waterford 3 Steam Electric StationSummaryThe Annual Radiological Environmental Operating Report presents data obtained through analyses ofenvironmental samples collected for Waterford 3's (W3) Radiological Environmental Monitoring Program(REMP) for the period January 1 through December 31, 2014. This report fulfills the requirements of W3Technical Specification 6.9.1.7.During 2014, gross beta radioactivity was detected in air and drinking/surface water locations. Resultsobtained at the indicator locations were similar to those obtained at the control location. Therefore, levelscontinue to remain at background.Radiological Environmental Monitoring ProgramW3 established the REMP prior to the station becoming operational (1985) to provide data on backgroundradiation and radioactivity normally present in the area. W3 has continued to monitor the environment bysampling 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. TheREMP utilizes indicator locations near the site to show any increases or buildup of radioactivity that mightoccur due. to station operation, and control locations farther away from the site to indicate the presence ofonly naturally occurring radioactivity. W3 compares indicator results with control, preoperational, andprevious years operational results to assess any impact W3 might have on the surrounding environment.In 2014, W3 collected environmental samples for radiological analysis. Based on the comparison resultsof indicator locations with control locations and previous studies, it was concluded that overall W3operations had no significant impact on plant environs. The review of 2014 data, in many cases, showedundetectable radiation levels in the environment and near background levels in significant pathwaysassociated with W3.Harmful Effects or Irreversible DamaqeThe REMP did not detect any harmful effects or evidence of irreversible damage in 2014. Therefore, noanalysis or planned course of action to alleviate problems was necessary.1 Annual Radiological 2014Environmental Operating Report Waterford 3 Steam Electric StationReporting LevelsW3's review indicates that no samples equaled or exceeded reporting levels for radioactivityconcentration 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, 2014 results didnot trigger any radiological monitoring program special reports.Radioactivity Not Attributable to W3The W3 REMP detected radioactivity attributable to other sources three times. These include the 25thChinese nuclear test explosion in 1980, the radioactivity plume release due to reactor core degradation atthe Chernobyl Nuclear Power Plant in 1986, and the airborne release from Dai-ichi, Fukushima followingthe Tohoku earthquake on March 11, 2011.Comparison to State ProgramW3 compared REMP data to the monitoring program of the Environmental Radiological Laboratory -Department of Environmental Quality Laboratory Services Division (ERL-DEQLSD). The ERL-DEQLSDand the W3 REMP entail similar radiological environmental monitoring program requirements. Bothprograms have obtained similar results over previous years.Sample Deviations* Milk SamplesSince milk samples for indicator location MKE-3 were unavailable for all quarters of 2014, broad leafvegetation sampling was performed as required by TRM Table 3.12-1. Broad leaf vegetation resultsare in section 2.7. Milk samples were collected from one control location and analyzed for Iodine-131and 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 2014.* Air SamplesThe air sample locations listed below failed to meet the requirement for sample continuity. Asdescribed in footnote (1) of TRM Table 3.12-1, deviations are permitted from the required samplingschedule due to malfunction of sampling equipment and other legitimate reasons.Location Sample Period Explanation of DeviationAPQ-1 04/28/14 -05/12/14 Sample pump running at lowcapacity2 Annual Radiological 2014Environmental Operating Report Waterford 3 Steam Electric Station* Missed SamplesOne TLD located at station N-1 was missing at the time of the first quarter exchange.

The REMP isdesigned for:* Analyzing important pathways for anticipated types and quantities of radionuclides releasedinto the environment.* Considering the possibility of a buildup of long-lived radionuclides in the environment andidentifying physical and biological accumulations that may contribute to human exposures." Considering the potential radiation exposure to plant and animal life in the environmentsurrounding W3." Correlating levels of radiation and radioactivity in the environment with radioactive releasesfrom station operation.1.2 Pathways MonitoredThe airborne, direct radiation, waterborne and ingestion pathways are monitored as required byW3 TRM Table 3.12-1. A description of the W3 REMP utilized to monitor the exposure pathwaysis 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 2014 sampling results with Section 3.0providing a summary of results for the monitored exposure pathways.1.3 Land Use CensusW3 conducts a land use census biennially, as required by Section 3.12.2 of the TRM. Thepurpose of this census is to identify changes in uses of land within five miles of W3 that wouldrequire modifications to the REMP and the Offsite Dose Calculation Manual (ODCM). The mostimportant criteria during this census are to determine the location in each sector of the nearest:1) Residence2) Animal milked for human consumption2 23) 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 datasheets." Comparing current census results to previous results.5 Annual RadiologicalEnvironmental Ooeratina Report2014Waterford 3 Steam Electric StationTable 1.1Radiological Environmental Sampling ProgramExposure Requirement Sample Point Description, Sampling and Type and FrequencyPathway Distance and Direction Collection Frequency Of AnalysesAirborne Radioiodine and ParticulatesThree samples from close to the three APQ-1 (NW, 0.81 Miles) -(West bank) Continuous sampler operation Radioiodine Canister 131SITE BOUNDARY locations, in different Located in soybean/sugarcane field off with sample collection bi- analysis bi-weekly.sectors, in or near sectors having the LA 18 east of LA 18/3141 intersection.highest calculated annual average weekly, or more frequently ifground level D/Q.

W3 did not detect any gamma radionuclides inthe quarterly air particulate composites or Iodine-1 31 in the radioiodine cartridges during thereporting period as has been the case in previous years. Indicator gross beta air particulateresults for 2014 were similar to those background levels obtained in previous years of theoperational REMP and well below preoperational levels as seen below. Results are reported as3annual average pCi/miMonitoring Period ResultPreoperational 0.0801983-2013 0.0202014 0.020Table 3.1, which includes gross beta concentrations for 2014, provides a comparison of theindicator and control means. It further emphasizes that the airborne pathway continues to remainat background levels. In addition, as shown in Attachment 2, the standard "t" test was used tocompare average gross beta activity from each indicator station to the average gross beta activityat the control station. The results from this test show the average activity detected at all indicatorstations 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 2014.2.2 Thermoluminescent Dosimetry Sample ResultsThe average exposure rates during 2014 are consistent with those from the preoperationalprogram and the previous five years of operation as seen in Figure 2-1. In particular, thepreoperational survey indicates that exposure rates ranged between 11 and 33 mrem/standardquarter with an average of 20 mrem/standard quarter. The range during the previous five years ofoperation was 9 to 16 mrem/standard quarter with an average exposure rate of 12mrem/standard quarter.A comparison of the indicator results to the control results, as seen in Table 3.1, shows that theaverage 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 differenceof six mrem.As shown in Attachment 2, Table 2.1, the standard "t" test was used to compare averageexposure 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 arestatistically 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 bydistance from the plant are expected due to a variety of factors not related to W3 plant operationsthat can affect background radiation in the vicinity of each TLD station. Direct radiationmeasurements at each TLD station have remained statistically the same in 2014 as previousyears of operation as evidenced on Attachment 2, Table 2.2. In addition, Radiological GaseousEffluents for 2014 were only a small fraction of the limits and are not expected to have any impacton environmental TLD measurements.20 Annual Radiological 2014Environmental Operating Report Waterford 3 Steam Electric Station2.3 Water Sample ResultsAnalytical results for 2014 drinking/surface water samples were similar to those reported inprevious years.DrinkinqlSurface WaterDrinking water samples also serve as surface water samples for W3. Therefore, monthly andquarterly gamma spectroscopy and tritium analyses of drinking water also satisfy the surfacewater sampling requirement.Composite drinking/surface water samples were collected from two indicators and one controllocation and analyzed for Iodine-1 31, gamma radionuclides and tritium. Results indicate that allmeasurements were below the calculated LLDs.Although gross beta was detected in the drinking/surface water samples, results for the indicatorlocations were below preoperational years and slightly above previous operational years as seenbelow. Results are reported as annual average pCi/I.Monitoring Period ResultPreoperational 7.01983-2013 4.72014 5.4Table 3.1, which includes gross beta concentrations for 2014, provides a comparison of theindicator and control means. It shows that the waterborne pathway continues to remain atbackground levels. In addition, as shown in Attachment 2, the standard "t" test was used tocompare average gross beta activity from indicator stations to the average gross beta activityfrom the control station. The results from the test show the average activity detected at oneindicator station is statistically the same as the average activity detected at the control station andone indicator station is statistically higher than the mean for the control location. Results areconsistent with historical data stated above. Therefore, W3 concluded that plant operations hadno significant impact on this pathway during 2014.Surface WaterSurface water samples were collected from one indicator location and analyzed for gammaradionuclides and tritium. Results indicate that all measurements were below the calculatedLLDs. Therefore, W3 concluded that plant operations had no significant impact on this pathwayduring 2014.2.4 Sediment Sample ResultsSediment samples were collected from two indicator locations and one control location andanalyzed for gamma radionuclides. Results indicate that all measurements were below thecalculated LLDs. Therefore, W3 concluded that plant operations had no significant impact on thispathway during 2014.21 Annual Radiological 2014Environmental Operating Report Waterford 3 Steam Electric Station2.5 Milk Sample ResultsSince milk samples for indicator location MKE-3 were unavailable for all quarters of 2014, broadleaf vegetation sampling was performed as required by TRM Table 3.12-1. Broad leaf vegetationresults are in section 2.7. Milk samples were collected from one control location and analyzed forIodine-1 31 and gamma radionuclides. Results indicate that all measurements were below thecalculated LLDs. Therefore, W3 concluded that plant operations had no significant impact on thispathway during 2014.2.6 Fish Sample ResultsFish samples were collected from two indicators and one control location and analyzed forgamma radionuclides. Results indicate that all measurements were below the calculated LLDs.Therefore, W3 concluded that plant operations had no significant impact on this pathway during2014.2.7 Broadleaf Vegetation Sample ResultsBroadleaf vegetation samples were collected from two indicators and one control location andanalyzed for Iodine-1 31 and gamma radionuclides. Results indicate that all measurements werebelow the calculated LLDs. Therefore, W3 concluded that plant operations had no significantimpact on this pathway during 2014.2.8 Land Use Census ResultsIn compliance with the Waterford 3 0DCM and TRM, the land use census was conductedSeptember 22 -September 24, 2014. The nearest residence, garden, beef cow, food productand milk animal in each sector within a five mile radius of the plant was located by visualinspection and verbal inquiry.Two new garden locations (sectors P and Q) were identified in 2014. Residence, milk cow, andgoat locations remained unchanged for 2014. Beef cows located in sector E at a distance of 2.9miles from the plant have been removed. A soybean field is located in sector N at a distance of0.6 miles from the plant. Based upon the locations identified in this survey, the locationsidentified in previous surveys and the locations currently being used to calculate dosecommitments from liquid and gaseous effluents released from W3, no REMP sampling locationchanges are necessary. Results of the 2014 biennial census are shown in Table 2.1.2.9 Interlaboratory Comparison ResultsTeledyne Brown Engineering, Inc. analyzed interlaboratory comparison samples for W3 to fulfillthe requirements of Section 5.7.2 of the ODCM.

The use of the test requires the assumption that the data within the populations are normallydistributed and that the true standard deviations of the mean are equal for both populations. Thestandard "t" test tests the hypothesis that the true means of both populations are equal. The "t" valuecan be calculated from the equation below (obtained from the CRC Standard Mathematical Tables,26th Edition (1981)):X-Y( n.= _ n+ -2  0.5 0.5.x -2 I+ JIwhere: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,,7 y = number of variables in second data set, andS 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,) is equal to the true mean of the second population (m y) assuming that the true standarddeviation of.both populations are equal (m x = m y). The calculated "t" value is compared to atabular "t" value such that:a if t > t p,n then reject the hypothesis when m > m y,b. if t < -t p,n then reject the hypothesis when m. < m y,c. if t > t p/2,n then reject the hypothesis when mx = m y,where t p/2,n and t p,n are the tabular "t" values, with a preselected error (5%), confidence level (1 -lp) or(1- p/2), and degrees of freedom n = nx + ny -2.
