: 1. EXECUTIVE SUMMARYThis document is a detailed report of the 2013 North Anna Nuclear Power StationRadiological Environmental Monitoring Program (REMP). It is submitted inaccordance with North Anna Unit 1 and 2 Technical Specification 5.6.2 and NorthAnna Independent Spent Fuel Storage Installation (ISFSI) Technical Specification 5.5.2. Radioactivity levels from January 1 through December 31, 2013, in water,silt, shoreline
: sediment, milk, aquatic biota, food products, vegetation, and directexposure pathways have been analyzed, evaluated and summarized.
The REMP isdesigned to confirm that radiological effluent releases are As Low As Reasonably Achievable (ALARA),
no undue environmental effects occur and the health andsafety of the public are protected.
The program also detects any unexpected environmental processes that could allow radiation accumulations in theenvironment or food pathway chains.Radiation and radioactivity in the environment is monitored within a 25-mileradius of the station.
North Anna Power Station personnel collect a variety ofsamples within this area. A number of sampling locations for each medium areselected using available meteorological, land use, and water use data. Two typesof samples are obtained.
Control samples are collected from areas that arebeyond the measurable influence of North Anna Power Station or any othernuclear facility.
These samples are used as reference data. Normal background radiation levels, or radiation present due to causes other than North Anna PowerStation, can be compared to the environment surrounding the station.
Indicator samples are the second sample type obtained.
These samples show how muchradiation is contributed to the environment by the station.
Indicator samples aretaken from areas close to the station where any station contribution will be at thehighest concentration.
Prior to station operation, samples were collected and analyzed to determine theamount of radioactivity present in the area. The resulting values are used as a"pre-operational baseline."
Analysis results from the indicator samples arecompared to both current control sample values and the pre-operational baselineto determine if changes in radioactivity levels are attributable to stationoperations, or causes such as the Chernobyl
: accident, Fukushima Daiichi ornatural variation.
Global Dosimetry Solutions provided thermoluminescent dosimetry (TLD) servicesand Teledyne Brown Engineering Environmental Services provided radioanalytical services.
Participation in an Interlaboratory Comparison Program provides anindependent check of sample measurement precision and accuracy.
Typically, radioactivity levels in the environment are so low that analysis values frequently fall below the minimum detection limits of state-of-the-art measurement methods.4 Because of this, the Nuclear Regulatory Commission (NRC) requires thatequipment used for radiological environmental monitoring must be able to detectspecified minimum Lower Limits of Detection (LLDs). This ensures that analysesare as accurate as possible.
The NRC also mandates a reporting level for certainradionuclides.
Licensed nuclear facilities must report the radionuclide activities in those environmental samples that are equal to or greater than the specified reporting level. Environmental radiation levels are sometimes referred to as apercent of the reporting level.Analytical results are reported for all possible radiation exposure pathways toman. These pathways include airborne, water, aquatic, terrestrial, and directradiation exposure.
The airborne exposure pathway includes radioactive airborneiodine and particulates, and precipitation.
The 2013 airborne results were similarto previous years. Fallout or natural radioactivity levels remained at levelsconsistent with past years' results.Water and aquatic exposure pathway samples include precipitation,
: surface, riverand well water, silt and shoreline sediments, and fish. The average tritium activityin surface water for 2013 was 4080 pCi/liter.
No other plant related isotopes werereported in any surface or river water. River water collected from the North AnnaRiver, 5.8 miles downstream of the site had an average tritium level of 4010pCi/liter.
No plant related isotopes were detected in quarterly precipitation samples.
Silt samples indicated the presence of naturally occurring potassium-40 and thorium and uranium decay daughters at levels consistent with the naturalbackground.
No plant related isotope was identified in any sample. Shoreline soil, which may provide a direct exposure
: pathway, indicated the presence ofpotassium-40 and thorium and uranium decay daughters also at levels consistent with natural levels. No plant related isotope was detected in the indicator orcontrol locations in shoreline soil. No plant related isotope was detected in fishsamples from either Lake Anna or the control location, Lake Orange.Soil samples, which are collected every three years from twelve stations, werecollected in 2013. Cs- 137 was identified in 10 of 11 indicator samples and thecontrol sample. For the indicator stations the average was 208.9 pCi/Kg while forthe control station the average was 329 pCi/Kg. During the preoperational phaseCs-137 was routinely detected and was attributed to fallout.
Levels during thisphase varied by location and date and ranged from 88 to 1390 pCi/Kg. Theaverage was 645 pCi/kg. The current levels are also varied significantly bylocation and date. The decrease in the average, and the fact that the averages forthe control location and the indicator locations are similar is indicative of fallout.No other plant related isotope was identified in soil samples during 2013.5 The terrestrial exposure pathway includes milk and food/vegetation products.
Noplant related radioisotope was detected in any milk samples.
Naturally occurring beryllium-7, potassium-40 and radionuclides associated with the uranium andthorium series were detected at environmental levels consistent with historical data. No plant related isotope was detected in any vegetation sample. Low levelsof Cs- 137 have been detected intermittently in past years.The direct exposure pathway measures environmental radiation doses by use ofthermoluminescent dosimeters (TLDs). TLD results have remained essentially constant over the years.During 2013, as in previous years, operation of the North Anna Power Station andthe Independent Spent Fuel Storage Installation (ISFSI) created no adverseenvironmental effects or health hazards.
The maximum total body dose calculated for a hypothetical individual at the station site boundary due to liquid andgaseous effluents released from the station during 2013 was 0.45 millirem.
Forreference, this dose may be compared to the 625 millirem average annualexposure to every person in the United States from natural and man-madesources.
Natural sources in the environment provide approximately 82% ofradiation exposure to man, while nuclear power contributes less than 0.1%.These results demonstrate not only compliance with federal and state regulations but also demonstrate the adequacy of radioactive
'effluent control at North AnnaPower Station.6
: 2. PROGRAM DESCRIPTION
===2.1 Introduction===
This report documents the 2013 North Anna Power Station operational Radiological Environmental Monitoring Program (REMP).The North Anna Power Station of Virginia Electric and Power Company (Dominion) is located on Lake Anna in Mineral,
: Virginia, approximately 35 miles southwest ofFredericksburg, Virginia.
The site consists of two units, each with a pressurized water reactor (PWR) nuclear steam supply system and turbine generator furnished by Westinghouse Electric Corporation.
Each unit has a gross electrical output of1029 megawatts electric (MWe). Unit 1 achieved commercial operation on June 6,1978 and Unit 2 on December 14, 1980. An independent spent fuel storagefacility was licensed for dry cask storage of spent fuel in 1998.The United States Nuclear Regulatory Commission (USNRC) regulations requirethat nuclear power plants be designed, constructed, and operated to keep levels ofradioactive material in effluents to unrestricted areas as low as reasonably achievable (ALARA).
To ensure these criteria are met, the operating license forNorth Anna Power Station includes Technical Specifications, which address therelease of radioactive effluents.
In-plant monitoring is used to ensure releaselimits are not exceeded.
As a precaution against unexpected or undefined environmental processes which might allow undue accumulation of radioactivity in the environment, a program for monitoring the plant environs is also includedin the North Anna Power Station Offsite Dose Calculation Manual (ODCM).North Anna Power Station is responsible for collecting the various indicator andcontrol environmental samples.
Global Dosimetry Solutions is utilized forprocessing the TLDs. Teledyne Brown Engineering Environmental Services (TBE)is utilized for sample analyses.
The results of the analyses are used to determine if changes in radioactivity levels may be attributable to station operations.
Measured values are compared with control levels, which vary with time due toexternal events, such as cosmic ray bombardment, nuclear weapons test falloutand seasonal variations of naturally occurring radioisotopes.
Data collected priorto station operation is used to indicate the degree of natural variation to beexpected.
The pre-operational data is compared with data collected during theoperational phase to assist in evaluating any radiological impact of stationoperation.
Occasionally samples of environmental media show the presence of man-madeisotopes.
As a method of referencing the measured radionuclide concentrations inthe sample media to a dose consequence to man, the data is compared to the7 reporting level concentrations listed in the USNRC Regulatory Guide 4.8 andNorth Anna's ODCM. These concentrations are based upon the annual dosecommitment recommended by 1OCFR50, Appendix I, to meet the criterion of "AsLow As Is Reasonably Achievable".
This report documents the results of the Radiological Environmental Monitoring Program for 2013 and satisfies the following objectives of the program:To provide measurements of radiation and of radioactive materials inthose exposure pathways and for those radionuclides that lead to thehighest potential radiation exposure of the maximum exposed member ofthe public resulting from station operations.
To supplement the radiological effluent monitoring program by verifying that radioactive effluents are within allowable limits...To identify changes in radioactivity in the environment.
> To verify that station operations have no detrimental effect on the healthand safety of the public.2.2 Sampling and Analysis ProgramTable 2-1 summarizes the 2013 sampling program for North Anna Power Station.All samples listed in Table 2-1 are taken at indicator locations except thoselabeled "control."

Rev. 1, November 1979. The LLD listed value is taken from the ODCM.For radioanalytic
: analyses, the values listed in the columns indicated as"Mean/Range" include any results above the Minimum Detectable Concentration, MDC. Results are considered true positives when the measured value exceedsboth the MDC and the 2(y error. For TLDs the mean and range include all values.A more detailed analysis of the data is given in Section 4 where a discussion of thevariations in the data explains many aspects that are not evident in the SummaryTable because of the basic limitation of data summaries.

The data reported in thefollowing tables are strictly counting statistics.
The reported error is two times the standarddeviation (2G) of the net activity.
Unless otherwise noted, the overall error (counting, samplesize, chemistry, errors, etc.) is estimated to be 2 to 5 times that listed. Results are considered true positives when the measured value exceeds both the MDC and the 2a error.Because of counting statistics, negative values, zeros and numbers below the MinimumDetectable Level (MDL) are statistically valid pieces of data'. For clarity of this report onlydetectable results are presented.
TBE's analytical methods meet the Lower Limit of Detection (LLD) requirements given in Table 2 of the USNRC Branch Technical

Except for TLDs,Teledyne Brown Engineering analyzed all samples throughout the year. Theprocedures and specifications followed for these analyses are as required in theTBE quality assurance manuals and laboratory procedures.
In addition tointernal quality control measurements performed by each laboratory, they alsoparticipate in an Interlaboratory Comparison Program.
Participation in thisprogram ensures that independent checks on the precision and accuracy of themeasurements of radioactive material in environmental samples are performed.
The results of the Interlaboratory Comparison Programs are provided inAppendix B.The predominant radioactivity detected throughout 2013 was that fromexternal
: sources, such as fallout from nuclear weapons tests and naturally occurring radionuclides.
Naturally occurring nuclides such as Be-7, K-40, Th-228 and Th-232 were detected in numerous samples.
Th-228 & Th-232 resultswere variable and are generally at levels higher than plant relatedradionuclides.
The following is a discussion and summary of the results of the environmental measurements taken during the 2013 reporting period.4.1 Gamma Exposure RateA thermoluminescent dosimeter (TLD) is an inorganic crystal used to detectambient radiation.
TLDs are placed in two concentric rings around the station.The inner ring is located at the site boundary, and the outer ring is located atapproximately five miles from the station.
TLDs are also placed in specialinterest areas, such as population areas and nearby residences.
Additional TLDs serve as controls.
Ambient radiation comes from naturally occurring radioisotopes in the air and soil, radiation from cosmic origin, fallout fromnuclear weapons testing, station effluents and direct radiation from the station.The results of the analyses are presented in Table 3-2. Figure 4-1 shows thehistorical trend of TLD exposure rate measurements.
Control and indicator averages indicate a steady relationship.
Two dosimeters made of CaF and LiFsensitive elements are deployed at each sampling location.
These TLDsreplaced the previously used CaSO4:Dy in Teflon TLDs in January 2001. The60 dose with the replacement TLDs is lower than that of the previously used TLDs.This will continue to be monitored.

Two badges are placed at each location.
The average levelof the 32 locations (two badges at each location) was 4.6 mR/standard monthwith a range of 1.6 to 9.2 mR/standard month. The highest quarterly averagereading for any single location was obtained at location NW-29/61.
This valuewas 7.7 mR/standard month. This location is on site on the north gate of theconstruction side laydown area. Quarterly and annual TLDs are also located attwelve environmental air sampling stations.
For the eleven indicator locations within 10 miles of the station the average quarterly reading was 3.8mR/standard month with a range of 1.9 to 6.3 mR/standard month. Theaverage annual reading for these locations was 3.4 mR/standard month with arange from 2.3 to 4.8 mR/standard month. The control location showed aquarterly average of 3.4 mR/standard month with a range of 2.9 to 3.9mR/standard month. Its annual reading was 3.6 mR/standard month. 10emergency sector TLDs, which are all located onsite had a quarterly average of5.4 mR/standard month with EPSP-9/ 10 having the highest quarterly averageof 7.8 mR/standard month. Eight other TLDs, designated C-1 thru C-8, which61 were pre-operational
: controls, were collected quarterly from four locations.
Stations C-3/4 and C-7/8 are designated controls.
These had a quarterly average of 3.6, while Station C-1/2 and C-5/6 had a quarterly average of 2.5mR/standard month with a range of 1.1 to 3.7 mR/standard month. Duringthe pre-operational period (starting in 1977) the doses were measured between4.3 and 8.8 mR/standard month.4.2 Airborne Gross BetaResults of the weekly gross beta analyses are presented in Table 3-3. A reviewof the historical plot in Figure 4-2, indicates gross beta activity levels haveremained relatively unchanged.
The drop indicated in 2009 may be a functionof a return to the vendor used from 1988 until 2001. This will be monitored inthe future to see if this is in fact the case. Inner and outer ring monitoring locations continue to show no significant variation in measured activities (seeFigure 4-3). This indicates that any station contribution is not measurable.
Gross beta activity found during the pre-operational and early operating periodof North Anna Power Station was higher because of nuclear weapons testing.During that time, nearly 740 nuclear weapons were tested worldwide.
In 1985weapons testing ceased, and with the exception of the Chernobyl accident in1986, airborne gross beta results have remained steady. During thepreoperational period of July 1, 1974 through March 31, 1978 gross betaactivities ranged from a low of 0.005 pCi/m3to a high of 0.75 pCi/m3.0.12 -0.1E 0.08 -: 0.06 -0 0.04 -0.02 -Control G'ta-24 Indicator Average Pre-op -Required LLDFigure 4-2 Historical Gross Beta in Air Particulates 62 2.50E-024L2.00E-021.50E-021.OOE-025.00E-03O.OOE+O0

Once a week thesamples are collected and analyzed.
The results of the analyses are presented in Table 3-4. These results are similar to pre-operational data and the resultsof samples taken prior to and after the 1986 accident in the Soviet Union atChernobyl and the effect of the Fukushima Daiichi event.4.4 Air Particulate GammaThe air particulate filters that are utilized for the weekly gross beta analysesare composited by location and analyzed quarterly by gamma spectroscopy.
The results are listed in Table 3-5. The results indicate the presence ofnaturally occurring Be-7, which is produced by cosmic processes.
Examination of pre-operational data indicates comparable measurements ofBe-7, as would be expected.
The results of these analyses indicate the lack ofstation effects on the environment.
63 4.5 Air Particulate Strontium Strontium-89 and 90 analyses are performed on the second quarter composites of air particulate filters from all monitoring stations.
There has been nodetection of these fission products at any of the indicator or control stations inrecent years.4.6 SoilSoil samples, which are collected every three years from twelve stations, werecollected in 2013. Cs-137 was identified in 10 of 11 indicator samples and thecontrol sample. For the indicator stations the average was 208.9 pCi/Kg whilefor the control station the average was 329 pCi/Kg. During the preoperational phase Cs-137 was routinely detected and was attributed to fallout.
Levelsduring this phase varied by location and date and ranged from 88 to 1390pCi/Kg. The average was 645 pCi/kg. The current levels are also variedsignificantly by location and date. The decrease in the average, and the factthat the averages for the control location and the indicator locations are similaris indicative of fallout.
No other plant related isotopes were identified in Soilsamples during 2013.4.7 Precipitation A sample of rain water was collected monthly at on-site station 01A andanalyzed for gross beta activity and H-3. The results are presented in Table 3-7. Twelve precipitation samples were obtained in 2013. Semi-annual composites are prepared and analyzed for gamma emitting isotopes inaccordance with program requirements.
No plant related isotopes were reportedin any precipitation water sample at the indicator location.
Naturally occurring gamma emitting radioisotopes were detected.
No positive H-3 result wasreported.
During the pre-operational period gross beta activity in rain waterwas expressed in nCi per square meter of the collector
: surface, thus a directcomparison cannot be made to the 2013 period. During the pre-operational period, tritium was measured in over half of the few quarterly composites made. This tritium activity ranged from 100 to 330 pCi/liter.
4.8 Cow MilkAnalysis of milk samples is generally the most sensitive indicator of fissionproduct existence in the terrestrial environment.
This pathway also shows64 measurable amounts of nuclear weapons testing fallout.
Therefore, this medianeeds to be evaluated very carefully when trying to determine if there is anyplant effect.Analysis results for cow milk are contained in Table 3-8. No sample indicated positive results.
Gamma spectroscopy did not detect the presence of anyisotopes related to the operation of North Anna. In years past, Cs-137 hasbeen detected sporadically.
These occurrences were attributed to residualglobal fallout from past atmospheric weapons testing.
Naturally occurring K-40 was detected in all samples.Once each quarter a sample from the collection station is analyzed forstrontium-89 and strontium-90.
Neither Sr-89 nor Sr-90 was detected.
Sr-90has been observed in the past. Pre-operational levels of 2.2 to 5.4 pCi/liter were measured for Sr-90. There has been a long-term activity trend for Sr-90showing a continuous decline.
It should be noted that strontium-90 is not apart of station effluents.
Its detection is the product of nuclear weaponstesting fallout.
This conclusion can be made based upon the fact that Sr-89and Sr-90 have not been detected in gaseous effluents released from thestation in many years, and the trend of consistent declining levels since thepre-operational period.4.9 Food Products and Vegetation Food/vegetation samples were collected from five locations and analyzed bygamma spectroscopy.
The results of the analyses are presented in Table 3-9.Low levels of Cs- 137, attributable to fallout, have been seen periodically invegetation samples.
As expected, naturally occurring potassium-40 andcosmogenic beryllium-7 were detected in most samples, and thorium-228 andother natural products, including Bi-214, were detected in some samples.
Noplant related isotopes were identified in any Vegetation sample during 2013.4.10 Well WaterWater was sampled quarterly from the onsite well at the metrology laboratory.
These samples were analyzed for gamma radiation and for tritium.
The secondquarter sample was analyzed by vendor for Sr-89, Sr-90, H-3, 1-131, andgamma emitters.
The results of these analyses are presented in Table 3-10. Noplant related isotopes were detected.
No gamma emitting isotopes were detectedduring the pre-operational period.65 4.11 River WaterSamples of water from the North Anna River were collected monthly.
Theanalyses are presented in Table 3-11. All monthly samples are analyzed bygamma spectroscopy.
The monthly samples were composited quarterly andanalyzed for tritium.
Additionally, the second quarter samples are analyzed forstrontium-89 and strontium-90 in accordance with program requirements.
There has been no detection of these fission products at any of the indicator orcontrol stations in recent years.No gamma emitting radioisotopes were positively identified in any of thesamples.
There was no measured activity of strontium-89 or strontium-90.
Tritium was measured in all four samples with an average annualconcentration of 4010 pCi/liter and a range of 3750 to 4330 pCi/liter.
Theselevels are comparable to those observed in previous years, see Figure 4-4. Noriver water samples were collected during the pre-operational period.River Water4500 45004000 40003500 4 3500-J 3000 30004&2500 2500 --$-tritium 2000 2000 --I-Req LLD1500 15001000 1000Figure 4-4Tritium in River water66 4.12 Surface WaterSamples of surface water were collected monthly from two stations, anindicator station located at the discharge lagoon and a control station located12.9 miles WNW. The samples were analyzed by gamma spectroscopy and foriodine-131 by radiochemical separation.
A quarterly composite from eachstation was prepared and analyzed for tritium.
Additionally, the secondquarter samples are analyzed for strontium-89 and strontium-90.
There hasbeen no positive indication of these fission products at any of the indicator orcontrol stations in recent years. The results are presented in Table 3-12.No non-naturally occurring gamma emitting radioisotopes, including iodinewere detected in any of the samples.
No tritium was detected at the controllocation.
The average level of tritium activity at the indicator station was 4080pCi/liter with a range of 3850 to 4370 pCi/liter.
Levels of tritium haveincreased since 1978 when the average level was below 300 pCi/liter.
Levels.measured at the indicator location (Station
: 8) are comparable to thosemeasured since 1986, see Figure 4-5. During the pre-operational period tritiumwas measured in several samples with concentrations between 90 and 250pCi/liter.

Buildup of radionuclides in bottom sediment could indirectly lead to increasing radioactivity levels infish.Sediment samples were collected during March and October from each of threelocations and were analyzed by gamma spectroscopy.
The October sampleswere analyzed for strontium-89 and strontium-90.
The results are presented inTable 3-13.No plant related isotopes were detected in 2013. The detection of Cs-137 inbottom sediment is historically common with positive indications usuallyapparent in both indicator and control samples.
The detection of Cs-137 is the68 result of accumulation and runoff into the lake of residual weapons testingfallout; its global presence has been well documented.
During the pre-operational period sediment samples were also analyzed by gammaspectroscopy.
Figure 4-6 shows the historical trend of Cs- 137 in sediments.
Neither Strontium-89 nor Strontium-90 was detected in any samples of aquaticsediment/silt in 2013. Strontium-90 has been detected occasionally in thepast at both the indicator and control locations and is attributable to falloutfrom past bomb tests. A number of naturally occurring radioisotopes weredetected in these samples at background levels.1600 -Station-1400 81200.91000 9800.600 Control400 -Sta-09A200 920--Station-o~ Cc W oM -' Z LCi)W L -) Z M M O0 5CFigure 4-6 Cs-137 in Sediment/Silt 4.14 Shoreline SoilShoreline soil/sediment, unlike bottom sediment, may provide a direct dose tohumans. Buildup of radioisotopes along the shoreline may provide a source ofdirect exposure for those using the area for commercial and recreational uses.Samples of shoreline soil were collected in April and October from indicator station 08. The samples were analyzed by gamma spectroscopy.
The Octobersample was analyzed for strontium-89 and strontium-90.
The results arepresented in Table 3-14.Naturally occurring radioisotopes were detected at concentrations equivalent tonormal background activities.
No plant related isotopes were detected in anyindicator or control samples analyzed.
Strontium-90 is often detected in thismedia, however as discussed previously, the presence of Sr-90 and Cs-137 is69 attributed to accumulation of residual global fallout from past atmospheric weapons testing.4.15 FishFour sample sets of fish, two from Lake Anna and two from the control station,Lake Orange, were collected during 2013 and analyzed by gammaspectroscopy.
Each sample set consisted of a sample of game species and asample of bottom-dwelling
: species, which were analyzed separately.
Theresults are presented in Table 3-15. Naturally occurring K-40 was detected inall samples.
No plant related isotopes were detected.
Cs- 137 was measured inpre-operational environmental fish samples.70

-Environmental Services as required by technical specifications for the Radiological Environmental Monitoring Program (REMP). TBE usesQA/QC samples provided by Eckeri & Zeigler Analytics, Inc, DOE's MixedAnalyte Performance Evaluation Program (MAPEP) and Environmental Resource Associates, (ERA) to monitor the quality of analytical processing associated with the REMP. The suite of samples is designed to be comparable with the pre-1996 US EPA Interlaboratory Cross-Check Program in terms ofsample number, matrices, and nuclides.

78 RESULTSInterlaboratory comparison program results are evaluated using TBE'scriterion.
Any sample analysis result that does not pass the criteria isinvestigated by TBE. Nonconformance Reports were generated and corrective actions taken as a result of this program.For the TBE laboratory, 178 out of 185 analyses performed met thespecified acceptance criteria.
Seven analyses (Sr-89 and Sr-90 inmilk, Co-57, Zn-65 and Sr-90 in soil, Cs-134 in air particulate andSr-90 in vegetation
[two low warning in a row]) did not meet thespecified acceptance criteria or internal QA requirements for thefollowing reason:1. Teledyne Brown Engineering's Analytics September 2013 Sr-89 in milk result of 63.9 pCi/L was lower than the knownvalue of 96.0 pCi/L. The failure was a result of analyst errorand was specific to the Analytics sample. Client samples forthe associated time period were evaluated and no clientsamples were affected by this failure.
NCR 13-152. Teledyne Brown Engineering's Analytics September 2013 Sr-90 in milk result of 8.88 pCi/L was lower than the knownvalue of 13.2 pCi/L. The failure was a result of analyst errorand was specific to the Analytics sample. Client samples forthe associated time period were evaluated and no clientsamples were affected by this failure.
NCR 13-153. & 4. Teledyne Brown Engineering's MAPEP September 2013Co-57 and Zn-65 in soil were evaluated as failing the falsepositive test. While MAPEP evaluated the results as failures, the gamma software listed the results as non identified 79 nuclides.
The two nuclides would never have been reportedas detected nuclides to a client. MAPEP does not allowlaboratories to put in qualifiers for the submitted data nor"less than" results.
MAPEP evaluates results based on therelationship between the activity and the uncertainty.
MAPEP spiked the soil sample with an extremely largeconcentration of Eu- 152, which was identified by the gammasoftware as an interfering
: nuclide, resulting in forced activityresults that were evaluated by MAPEP as detected Co-57 andZn-65. No client samples were affected by these failures.
NCR 13-145. Teledyne Brown Engineering's MAPEP September 2013 Sr-90in soil result of 664 Bq/kg was higher than the known valueof 460 Bq/kg, exceeding the upper control limit of 598Bq/kg. An incorrect Sr-90 result was entered into theMAPEP database.
The correct Sr-90 activity of 322 Bq/kgwould have been evaluated as acceptable with warning.
Noclient samples were affected by this failure.
NCR 13-146. Teledyne Brown Engineering's MAPEP September 2013 Cs-134 in air particulate activity of -0.570 Bq/sample wasevaluated as a failed false positive test, based on MAPEP'sevaluation of the result as a significant negative value at 3standard deviations.
A negative number would never havebeen reported as a detected nuclide to a client, therefore noclient samples were affected by this failure.
NCR 13-147. Teledyne Brown Engineering's MAPEP September 2013 Sr-90in vegetation result was investigated due to two low warningsin a row. It appears the September sample was double80 spiked with carrier, resulting in a low activity.
With arecovery of around 50% lower, the Sr-90 result would havefallen within the acceptance range. No client samples wereaffected by this issue. NCR 13-14A summary of TBE's results is provided in the tables on the following pages for the required sample matrix types and isotopic distribution.
Delineated in the table for each of the media/analysis combinations, are: the specific radionuclide; its result; analytical date; the knownvalues supplied by the providers; pass or fail criteria.

1. EXECUTIVE SUMMARYThis document is a detailed report of the 2013 North Anna Nuclear Power StationRadiological Environmental Monitoring Program (REMP). It is submitted inaccordance with North Anna Unit 1 and 2 Technical Specification 5.6.2 and NorthAnna Independent Spent Fuel Storage Installation (ISFSI) Technical Specification 5.5.2. Radioactivity levels from January 1 through December 31, 2013, in water,silt, shoreline
sediment, milk, aquatic biota, food products, vegetation, and directexposure pathways have been analyzed, evaluated and summarized.

The REMP isdesigned to confirm that radiological effluent releases are As Low As Reasonably Achievable (ALARA),

no undue environmental effects occur and the health andsafety of the public are protected.

The program also detects any unexpected environmental processes that could allow radiation accumulations in theenvironment or food pathway chains.Radiation and radioactivity in the environment is monitored within a 25-mileradius of the station.

North Anna Power Station personnel collect a variety ofsamples within this area. A number of sampling locations for each medium areselected using available meteorological, land use, and water use data. Two typesof samples are obtained.

Control samples are collected from areas that arebeyond the measurable influence of North Anna Power Station or any othernuclear facility.

These samples are used as reference data. Normal background radiation levels, or radiation present due to causes other than North Anna PowerStation, can be compared to the environment surrounding the station.

Indicator samples are the second sample type obtained.

These samples show how muchradiation is contributed to the environment by the station.

Indicator samples aretaken from areas close to the station where any station contribution will be at thehighest concentration.

Prior to station operation, samples were collected and analyzed to determine theamount of radioactivity present in the area. The resulting values are used as a"pre-operational baseline."

Analysis results from the indicator samples arecompared to both current control sample values and the pre-operational baselineto determine if changes in radioactivity levels are attributable to stationoperations, or causes such as the Chernobyl

accident, Fukushima Daiichi ornatural variation.

Global Dosimetry Solutions provided thermoluminescent dosimetry (TLD) servicesand Teledyne Brown Engineering Environmental Services provided radioanalytical services.

Participation in an Interlaboratory Comparison Program provides anindependent check of sample measurement precision and accuracy.

Typically, radioactivity levels in the environment are so low that analysis values frequently fall below the minimum detection limits of state-of-the-art measurement methods.4 Because of this, the Nuclear Regulatory Commission (NRC) requires thatequipment used for radiological environmental monitoring must be able to detectspecified minimum Lower Limits of Detection (LLDs). This ensures that analysesare as accurate as possible.

The NRC also mandates a reporting level for certainradionuclides.

Licensed nuclear facilities must report the radionuclide activities in those environmental samples that are equal to or greater than the specified reporting level. Environmental radiation levels are sometimes referred to as apercent of the reporting level.Analytical results are reported for all possible radiation exposure pathways toman. These pathways include airborne, water, aquatic, terrestrial, and directradiation exposure.

The airborne exposure pathway includes radioactive airborneiodine and particulates, and precipitation.

The 2013 airborne results were similarto previous years. Fallout or natural radioactivity levels remained at levelsconsistent with past years' results.Water and aquatic exposure pathway samples include precipitation,

surface, riverand well water, silt and shoreline sediments, and fish. The average tritium activityin surface water for 2013 was 4080 pCi/liter.

No other plant related isotopes werereported in any surface or river water. River water collected from the North AnnaRiver, 5.8 miles downstream of the site had an average tritium level of 4010pCi/liter.

No plant related isotopes were detected in quarterly precipitation samples.

Silt samples indicated the presence of naturally occurring potassium-40 and thorium and uranium decay daughters at levels consistent with the naturalbackground.

No plant related isotope was identified in any sample. Shoreline soil, which may provide a direct exposure

pathway, indicated the presence ofpotassium-40 and thorium and uranium decay daughters also at levels consistent with natural levels. No plant related isotope was detected in the indicator orcontrol locations in shoreline soil. No plant related isotope was detected in fishsamples from either Lake Anna or the control location, Lake Orange.Soil samples, which are collected every three years from twelve stations, werecollected in 2013. Cs- 137 was identified in 10 of 11 indicator samples and thecontrol sample. For the indicator stations the average was 208.9 pCi/Kg while forthe control station the average was 329 pCi/Kg. During the preoperational phaseCs-137 was routinely detected and was attributed to fallout.

Levels during thisphase varied by location and date and ranged from 88 to 1390 pCi/Kg. Theaverage was 645 pCi/kg. The current levels are also varied significantly bylocation and date. The decrease in the average, and the fact that the averages forthe control location and the indicator locations are similar is indicative of fallout.No other plant related isotope was identified in soil samples during 2013.5 The terrestrial exposure pathway includes milk and food/vegetation products.

Noplant related radioisotope was detected in any milk samples.

Naturally occurring beryllium-7, potassium-40 and radionuclides associated with the uranium andthorium series were detected at environmental levels consistent with historical data. No plant related isotope was detected in any vegetation sample. Low levelsof Cs- 137 have been detected intermittently in past years.The direct exposure pathway measures environmental radiation doses by use ofthermoluminescent dosimeters (TLDs). TLD results have remained essentially constant over the years.During 2013, as in previous years, operation of the North Anna Power Station andthe Independent Spent Fuel Storage Installation (ISFSI) created no adverseenvironmental effects or health hazards.

The maximum total body dose calculated for a hypothetical individual at the station site boundary due to liquid andgaseous effluents released from the station during 2013 was 0.45 millirem.

Forreference, this dose may be compared to the 625 millirem average annualexposure to every person in the United States from natural and man-madesources.

Natural sources in the environment provide approximately 82% ofradiation exposure to man, while nuclear power contributes less than 0.1%.These results demonstrate not only compliance with federal and state regulations but also demonstrate the adequacy of radioactive

'effluent control at North AnnaPower Station.6

2. PROGRAM DESCRIPTION

2.1 Introduction

This report documents the 2013 North Anna Power Station operational Radiological Environmental Monitoring Program (REMP).The North Anna Power Station of Virginia Electric and Power Company (Dominion) is located on Lake Anna in Mineral,

Virginia, approximately 35 miles southwest ofFredericksburg, Virginia.

The site consists of two units, each with a pressurized water reactor (PWR) nuclear steam supply system and turbine generator furnished by Westinghouse Electric Corporation.

Each unit has a gross electrical output of1029 megawatts electric (MWe). Unit 1 achieved commercial operation on June 6,1978 and Unit 2 on December 14, 1980. An independent spent fuel storagefacility was licensed for dry cask storage of spent fuel in 1998.The United States Nuclear Regulatory Commission (USNRC) regulations requirethat nuclear power plants be designed, constructed, and operated to keep levels ofradioactive material in effluents to unrestricted areas as low as reasonably achievable (ALARA).

To ensure these criteria are met, the operating license forNorth Anna Power Station includes Technical Specifications, which address therelease of radioactive effluents.

In-plant monitoring is used to ensure releaselimits are not exceeded.

As a precaution against unexpected or undefined environmental processes which might allow undue accumulation of radioactivity in the environment, a program for monitoring the plant environs is also includedin the North Anna Power Station Offsite Dose Calculation Manual (ODCM).North Anna Power Station is responsible for collecting the various indicator andcontrol environmental samples.

Global Dosimetry Solutions is utilized forprocessing the TLDs. Teledyne Brown Engineering Environmental Services (TBE)is utilized for sample analyses.

The results of the analyses are used to determine if changes in radioactivity levels may be attributable to station operations.

Measured values are compared with control levels, which vary with time due toexternal events, such as cosmic ray bombardment, nuclear weapons test falloutand seasonal variations of naturally occurring radioisotopes.

Data collected priorto station operation is used to indicate the degree of natural variation to beexpected.

The pre-operational data is compared with data collected during theoperational phase to assist in evaluating any radiological impact of stationoperation.

Occasionally samples of environmental media show the presence of man-madeisotopes.

As a method of referencing the measured radionuclide concentrations inthe sample media to a dose consequence to man, the data is compared to the7 reporting level concentrations listed in the USNRC Regulatory Guide 4.8 andNorth Anna's ODCM. These concentrations are based upon the annual dosecommitment recommended by 1OCFR50, Appendix I, to meet the criterion of "AsLow As Is Reasonably Achievable".

This report documents the results of the Radiological Environmental Monitoring Program for 2013 and satisfies the following objectives of the program:To provide measurements of radiation and of radioactive materials inthose exposure pathways and for those radionuclides that lead to thehighest potential radiation exposure of the maximum exposed member ofthe public resulting from station operations.

To supplement the radiological effluent monitoring program by verifying that radioactive effluents are within allowable limits...To identify changes in radioactivity in the environment.

> To verify that station operations have no detrimental effect on the healthand safety of the public.2.2 Sampling and Analysis ProgramTable 2-1 summarizes the 2013 sampling program for North Anna Power Station.All samples listed in Table 2-1 are taken at indicator locations except thoselabeled "control."

3. ANALYTICAL RESULTS3.1 Summary of ResultsIn accordance with the North Anna Offsite Dose Calculation Manual (ODCM), asummary table of the analytical results has been prepared and is presented inTable 3-1. This data is presented in accordance with the format of the USNRCBranch Technical
Position, "Acceptable Radiological Environmental Monitoring Program",

Rev. 1, November 1979. The LLD listed value is taken from the ODCM.For radioanalytic

analyses, the values listed in the columns indicated as"Mean/Range" include any results above the Minimum Detectable Concentration, MDC. Results are considered true positives when the measured value exceedsboth the MDC and the 2(y error. For TLDs the mean and range include all values.A more detailed analysis of the data is given in Section 4 where a discussion of thevariations in the data explains many aspects that are not evident in the SummaryTable because of the basic limitation of data summaries.

The data reported in thefollowing tables are strictly counting statistics.

The reported error is two times the standarddeviation (2G) of the net activity.

Unless otherwise noted, the overall error (counting, samplesize, chemistry, errors, etc.) is estimated to be 2 to 5 times that listed. Results are considered true positives when the measured value exceeds both the MDC and the 2a error.Because of counting statistics, negative values, zeros and numbers below the MinimumDetectable Level (MDL) are statistically valid pieces of data'. For clarity of this report onlydetectable results are presented.

TBE's analytical methods meet the Lower Limit of Detection (LLD) requirements given in Table 2 of the USNRC Branch Technical

Except for TLDs,Teledyne Brown Engineering analyzed all samples throughout the year. Theprocedures and specifications followed for these analyses are as required in theTBE quality assurance manuals and laboratory procedures.

In addition tointernal quality control measurements performed by each laboratory, they alsoparticipate in an Interlaboratory Comparison Program.

Participation in thisprogram ensures that independent checks on the precision and accuracy of themeasurements of radioactive material in environmental samples are performed.

The results of the Interlaboratory Comparison Programs are provided inAppendix B.The predominant radioactivity detected throughout 2013 was that fromexternal

sources, such as fallout from nuclear weapons tests and naturally occurring radionuclides.

Naturally occurring nuclides such as Be-7, K-40, Th-228 and Th-232 were detected in numerous samples.

Th-228 & Th-232 resultswere variable and are generally at levels higher than plant relatedradionuclides.

The following is a discussion and summary of the results of the environmental measurements taken during the 2013 reporting period.4.1 Gamma Exposure RateA thermoluminescent dosimeter (TLD) is an inorganic crystal used to detectambient radiation.

TLDs are placed in two concentric rings around the station.The inner ring is located at the site boundary, and the outer ring is located atapproximately five miles from the station.

TLDs are also placed in specialinterest areas, such as population areas and nearby residences.

Additional TLDs serve as controls.

Ambient radiation comes from naturally occurring radioisotopes in the air and soil, radiation from cosmic origin, fallout fromnuclear weapons testing, station effluents and direct radiation from the station.The results of the analyses are presented in Table 3-2. Figure 4-1 shows thehistorical trend of TLD exposure rate measurements.

Control and indicator averages indicate a steady relationship.

Two dosimeters made of CaF and LiFsensitive elements are deployed at each sampling location.

These TLDsreplaced the previously used CaSO4:Dy in Teflon TLDs in January 2001. The60 dose with the replacement TLDs is lower than that of the previously used TLDs.This will continue to be monitored.

Two badges are placed at each location.

The average levelof the 32 locations (two badges at each location) was 4.6 mR/standard monthwith a range of 1.6 to 9.2 mR/standard month. The highest quarterly averagereading for any single location was obtained at location NW-29/61.

This valuewas 7.7 mR/standard month. This location is on site on the north gate of theconstruction side laydown area. Quarterly and annual TLDs are also located attwelve environmental air sampling stations.

For the eleven indicator locations within 10 miles of the station the average quarterly reading was 3.8mR/standard month with a range of 1.9 to 6.3 mR/standard month. Theaverage annual reading for these locations was 3.4 mR/standard month with arange from 2.3 to 4.8 mR/standard month. The control location showed aquarterly average of 3.4 mR/standard month with a range of 2.9 to 3.9mR/standard month. Its annual reading was 3.6 mR/standard month. 10emergency sector TLDs, which are all located onsite had a quarterly average of5.4 mR/standard month with EPSP-9/ 10 having the highest quarterly averageof 7.8 mR/standard month. Eight other TLDs, designated C-1 thru C-8, which61 were pre-operational

controls, were collected quarterly from four locations.

Stations C-3/4 and C-7/8 are designated controls.

These had a quarterly average of 3.6, while Station C-1/2 and C-5/6 had a quarterly average of 2.5mR/standard month with a range of 1.1 to 3.7 mR/standard month. Duringthe pre-operational period (starting in 1977) the doses were measured between4.3 and 8.8 mR/standard month.4.2 Airborne Gross BetaResults of the weekly gross beta analyses are presented in Table 3-3. A reviewof the historical plot in Figure 4-2, indicates gross beta activity levels haveremained relatively unchanged.

The drop indicated in 2009 may be a functionof a return to the vendor used from 1988 until 2001. This will be monitored inthe future to see if this is in fact the case. Inner and outer ring monitoring locations continue to show no significant variation in measured activities (seeFigure 4-3). This indicates that any station contribution is not measurable.

Gross beta activity found during the pre-operational and early operating periodof North Anna Power Station was higher because of nuclear weapons testing.During that time, nearly 740 nuclear weapons were tested worldwide.

In 1985weapons testing ceased, and with the exception of the Chernobyl accident in1986, airborne gross beta results have remained steady. During thepreoperational period of July 1, 1974 through March 31, 1978 gross betaactivities ranged from a low of 0.005 pCi/m3to a high of 0.75 pCi/m3.0.12 -0.1E 0.08 -: 0.06 -0 0.04 -0.02 -Control G'ta-24 Indicator Average Pre-op -Required LLDFigure 4-2 Historical Gross Beta in Air Particulates 62 2.50E-024L2.00E-021.50E-021.OOE-025.00E-03O.OOE+O0

Once a week thesamples are collected and analyzed.

The results of the analyses are presented in Table 3-4. These results are similar to pre-operational data and the resultsof samples taken prior to and after the 1986 accident in the Soviet Union atChernobyl and the effect of the Fukushima Daiichi event.4.4 Air Particulate GammaThe air particulate filters that are utilized for the weekly gross beta analysesare composited by location and analyzed quarterly by gamma spectroscopy.

The results are listed in Table 3-5. The results indicate the presence ofnaturally occurring Be-7, which is produced by cosmic processes.

Examination of pre-operational data indicates comparable measurements ofBe-7, as would be expected.

The results of these analyses indicate the lack ofstation effects on the environment.

63 4.5 Air Particulate Strontium Strontium-89 and 90 analyses are performed on the second quarter composites of air particulate filters from all monitoring stations.

There has been nodetection of these fission products at any of the indicator or control stations inrecent years.4.6 SoilSoil samples, which are collected every three years from twelve stations, werecollected in 2013. Cs-137 was identified in 10 of 11 indicator samples and thecontrol sample. For the indicator stations the average was 208.9 pCi/Kg whilefor the control station the average was 329 pCi/Kg. During the preoperational phase Cs-137 was routinely detected and was attributed to fallout.

Levelsduring this phase varied by location and date and ranged from 88 to 1390pCi/Kg. The average was 645 pCi/kg. The current levels are also variedsignificantly by location and date. The decrease in the average, and the factthat the averages for the control location and the indicator locations are similaris indicative of fallout.

No other plant related isotopes were identified in Soilsamples during 2013.4.7 Precipitation A sample of rain water was collected monthly at on-site station 01A andanalyzed for gross beta activity and H-3. The results are presented in Table 3-7. Twelve precipitation samples were obtained in 2013. Semi-annual composites are prepared and analyzed for gamma emitting isotopes inaccordance with program requirements.

No plant related isotopes were reportedin any precipitation water sample at the indicator location.

Naturally occurring gamma emitting radioisotopes were detected.

No positive H-3 result wasreported.

During the pre-operational period gross beta activity in rain waterwas expressed in nCi per square meter of the collector

surface, thus a directcomparison cannot be made to the 2013 period. During the pre-operational period, tritium was measured in over half of the few quarterly composites made. This tritium activity ranged from 100 to 330 pCi/liter.

4.8 Cow MilkAnalysis of milk samples is generally the most sensitive indicator of fissionproduct existence in the terrestrial environment.

This pathway also shows64 measurable amounts of nuclear weapons testing fallout.

Therefore, this medianeeds to be evaluated very carefully when trying to determine if there is anyplant effect.Analysis results for cow milk are contained in Table 3-8. No sample indicated positive results.

Gamma spectroscopy did not detect the presence of anyisotopes related to the operation of North Anna. In years past, Cs-137 hasbeen detected sporadically.

These occurrences were attributed to residualglobal fallout from past atmospheric weapons testing.

Naturally occurring K-40 was detected in all samples.Once each quarter a sample from the collection station is analyzed forstrontium-89 and strontium-90.

Neither Sr-89 nor Sr-90 was detected.

Sr-90has been observed in the past. Pre-operational levels of 2.2 to 5.4 pCi/liter were measured for Sr-90. There has been a long-term activity trend for Sr-90showing a continuous decline.

It should be noted that strontium-90 is not apart of station effluents.

Its detection is the product of nuclear weaponstesting fallout.

This conclusion can be made based upon the fact that Sr-89and Sr-90 have not been detected in gaseous effluents released from thestation in many years, and the trend of consistent declining levels since thepre-operational period.4.9 Food Products and Vegetation Food/vegetation samples were collected from five locations and analyzed bygamma spectroscopy.

The results of the analyses are presented in Table 3-9.Low levels of Cs- 137, attributable to fallout, have been seen periodically invegetation samples.

As expected, naturally occurring potassium-40 andcosmogenic beryllium-7 were detected in most samples, and thorium-228 andother natural products, including Bi-214, were detected in some samples.

Noplant related isotopes were identified in any Vegetation sample during 2013.4.10 Well WaterWater was sampled quarterly from the onsite well at the metrology laboratory.

These samples were analyzed for gamma radiation and for tritium.

The secondquarter sample was analyzed by vendor for Sr-89, Sr-90, H-3, 1-131, andgamma emitters.

The results of these analyses are presented in Table 3-10. Noplant related isotopes were detected.

No gamma emitting isotopes were detectedduring the pre-operational period.65 4.11 River WaterSamples of water from the North Anna River were collected monthly.

Theanalyses are presented in Table 3-11. All monthly samples are analyzed bygamma spectroscopy.

The monthly samples were composited quarterly andanalyzed for tritium.

Additionally, the second quarter samples are analyzed forstrontium-89 and strontium-90 in accordance with program requirements.

There has been no detection of these fission products at any of the indicator orcontrol stations in recent years.No gamma emitting radioisotopes were positively identified in any of thesamples.

There was no measured activity of strontium-89 or strontium-90.

Tritium was measured in all four samples with an average annualconcentration of 4010 pCi/liter and a range of 3750 to 4330 pCi/liter.

Theselevels are comparable to those observed in previous years, see Figure 4-4. Noriver water samples were collected during the pre-operational period.River Water4500 45004000 40003500 4 3500-J 3000 30004&2500 2500 --$-tritium 2000 2000 --I-Req LLD1500 15001000 1000Figure 4-4Tritium in River water66 4.12 Surface WaterSamples of surface water were collected monthly from two stations, anindicator station located at the discharge lagoon and a control station located12.9 miles WNW. The samples were analyzed by gamma spectroscopy and foriodine-131 by radiochemical separation.

A quarterly composite from eachstation was prepared and analyzed for tritium.

Additionally, the secondquarter samples are analyzed for strontium-89 and strontium-90.

There hasbeen no positive indication of these fission products at any of the indicator orcontrol stations in recent years. The results are presented in Table 3-12.No non-naturally occurring gamma emitting radioisotopes, including iodinewere detected in any of the samples.

No tritium was detected at the controllocation.

The average level of tritium activity at the indicator station was 4080pCi/liter with a range of 3850 to 4370 pCi/liter.

Levels of tritium haveincreased since 1978 when the average level was below 300 pCi/liter.

Levels.measured at the indicator location (Station

8) are comparable to thosemeasured since 1986, see Figure 4-5. During the pre-operational period tritiumwas measured in several samples with concentrations between 90 and 250pCi/liter.

Buildup of radionuclides in bottom sediment could indirectly lead to increasing radioactivity levels infish.Sediment samples were collected during March and October from each of threelocations and were analyzed by gamma spectroscopy.

The October sampleswere analyzed for strontium-89 and strontium-90.

The results are presented inTable 3-13.No plant related isotopes were detected in 2013. The detection of Cs-137 inbottom sediment is historically common with positive indications usuallyapparent in both indicator and control samples.

The detection of Cs-137 is the68 result of accumulation and runoff into the lake of residual weapons testingfallout; its global presence has been well documented.

During the pre-operational period sediment samples were also analyzed by gammaspectroscopy.

Figure 4-6 shows the historical trend of Cs- 137 in sediments.

Neither Strontium-89 nor Strontium-90 was detected in any samples of aquaticsediment/silt in 2013. Strontium-90 has been detected occasionally in thepast at both the indicator and control locations and is attributable to falloutfrom past bomb tests. A number of naturally occurring radioisotopes weredetected in these samples at background levels.1600 -Station-1400 81200.91000 9800.600 Control400 -Sta-09A200 920--Station-o~ Cc W oM -' Z LCi)W L -) Z M M O0 5CFigure 4-6 Cs-137 in Sediment/Silt 4.14 Shoreline SoilShoreline soil/sediment, unlike bottom sediment, may provide a direct dose tohumans. Buildup of radioisotopes along the shoreline may provide a source ofdirect exposure for those using the area for commercial and recreational uses.Samples of shoreline soil were collected in April and October from indicator station 08. The samples were analyzed by gamma spectroscopy.

The Octobersample was analyzed for strontium-89 and strontium-90.

The results arepresented in Table 3-14.Naturally occurring radioisotopes were detected at concentrations equivalent tonormal background activities.

No plant related isotopes were detected in anyindicator or control samples analyzed.

Strontium-90 is often detected in thismedia, however as discussed previously, the presence of Sr-90 and Cs-137 is69 attributed to accumulation of residual global fallout from past atmospheric weapons testing.4.15 FishFour sample sets of fish, two from Lake Anna and two from the control station,Lake Orange, were collected during 2013 and analyzed by gammaspectroscopy.

Each sample set consisted of a sample of game species and asample of bottom-dwelling

species, which were analyzed separately.

Theresults are presented in Table 3-15. Naturally occurring K-40 was detected inall samples.

No plant related isotopes were detected.

Cs- 137 was measured inpre-operational environmental fish samples.70

-Environmental Services as required by technical specifications for the Radiological Environmental Monitoring Program (REMP). TBE usesQA/QC samples provided by Eckeri & Zeigler Analytics, Inc, DOE's MixedAnalyte Performance Evaluation Program (MAPEP) and Environmental Resource Associates, (ERA) to monitor the quality of analytical processing associated with the REMP. The suite of samples is designed to be comparable with the pre-1996 US EPA Interlaboratory Cross-Check Program in terms ofsample number, matrices, and nuclides.

78 RESULTSInterlaboratory comparison program results are evaluated using TBE'scriterion.

Any sample analysis result that does not pass the criteria isinvestigated by TBE. Nonconformance Reports were generated and corrective actions taken as a result of this program.For the TBE laboratory, 178 out of 185 analyses performed met thespecified acceptance criteria.

Seven analyses (Sr-89 and Sr-90 inmilk, Co-57, Zn-65 and Sr-90 in soil, Cs-134 in air particulate andSr-90 in vegetation

[two low warning in a row]) did not meet thespecified acceptance criteria or internal QA requirements for thefollowing reason:1. Teledyne Brown Engineering's Analytics September 2013 Sr-89 in milk result of 63.9 pCi/L was lower than the knownvalue of 96.0 pCi/L. The failure was a result of analyst errorand was specific to the Analytics sample. Client samples forthe associated time period were evaluated and no clientsamples were affected by this failure.

NCR 13-152. Teledyne Brown Engineering's Analytics September 2013 Sr-90 in milk result of 8.88 pCi/L was lower than the knownvalue of 13.2 pCi/L. The failure was a result of analyst errorand was specific to the Analytics sample. Client samples forthe associated time period were evaluated and no clientsamples were affected by this failure.

NCR 13-153. & 4. Teledyne Brown Engineering's MAPEP September 2013Co-57 and Zn-65 in soil were evaluated as failing the falsepositive test. While MAPEP evaluated the results as failures, the gamma software listed the results as non identified 79 nuclides.

The two nuclides would never have been reportedas detected nuclides to a client. MAPEP does not allowlaboratories to put in qualifiers for the submitted data nor"less than" results.

MAPEP evaluates results based on therelationship between the activity and the uncertainty.

MAPEP spiked the soil sample with an extremely largeconcentration of Eu- 152, which was identified by the gammasoftware as an interfering

nuclide, resulting in forced activityresults that were evaluated by MAPEP as detected Co-57 andZn-65. No client samples were affected by these failures.

NCR 13-145. Teledyne Brown Engineering's MAPEP September 2013 Sr-90in soil result of 664 Bq/kg was higher than the known valueof 460 Bq/kg, exceeding the upper control limit of 598Bq/kg. An incorrect Sr-90 result was entered into theMAPEP database.

The correct Sr-90 activity of 322 Bq/kgwould have been evaluated as acceptable with warning.

Noclient samples were affected by this failure.

NCR 13-146. Teledyne Brown Engineering's MAPEP September 2013 Cs-134 in air particulate activity of -0.570 Bq/sample wasevaluated as a failed false positive test, based on MAPEP'sevaluation of the result as a significant negative value at 3standard deviations.

A negative number would never havebeen reported as a detected nuclide to a client, therefore noclient samples were affected by this failure.

NCR 13-147. Teledyne Brown Engineering's MAPEP September 2013 Sr-90in vegetation result was investigated due to two low warningsin a row. It appears the September sample was double80 spiked with carrier, resulting in a low activity.

With arecovery of around 50% lower, the Sr-90 result would havefallen within the acceptance range. No client samples wereaffected by this issue. NCR 13-14A summary of TBE's results is provided in the tables on the following pages for the required sample matrix types and isotopic distribution.

Delineated in the table for each of the media/analysis combinations, are: the specific radionuclide; its result; analytical date; the knownvalues supplied by the providers; pass or fail criteria.

A large concentration ofEu-152 was spiked into the sample, causing interference in the analysis.

Gamma software irecognized the interference and identified them asnot detected.

MAPEP does not allow clients to enter non-detect designation.

Soil, Sr-90 -incorrect results were submitted to MAPEP. Should have been 332 bq/kg, which would have passed.AP, Cs-134 -MAPEP evaluated the -0.570 as a failed false positive test. No client samples were affected by these failures.

NCR 13-04Vegetation, Sr-90 -it appears that the carrier was double spiked into the sample, resulting in the low activity for this sample.
