SUMMARY

This document is a detailed report of the 2013 North Anna Nuclear Power Station Radiological Environmental Monitoring Program (REMP). It is submitted in accordance with North Anna Unit 1 and 2 Technical Specification 5.6.2 and North Anna 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 direct exposure pathways have been analyzed, evaluated and summarized.

The REMP is designed to confirm that radiological effluent releases are As Low As Reasonably Achievable (ALARA), no undue environmental effects occur and the health and safety of the public are protected.

The program also detects any unexpected environmental processes that could allow radiation accumulations in the environment or food pathway chains.Radiation and radioactivity in the environment is monitored within a 25-mile radius of the station. North Anna Power Station personnel collect a variety of samples within this area. A number of sampling locations for each medium are selected using available meteorological, land use, and water use data. Two types of samples are obtained.

Control samples are collected from areas that are beyond the measurable influence of North Anna Power Station or any other nuclear facility.

These samples are used as reference data. Normal background radiation levels, or radiation present due to causes other than North Anna Power Station, can be compared to the environment surrounding the station. Indicator samples are the second sample type obtained.

These samples show how much radiation is contributed to the environment by the station. Indicator samples are taken from areas close to the station where any station contribution will be at the highest concentration.

Prior to station operation, samples were collected and analyzed to determine the amount of radioactivity present in the area. The resulting values are used as a"pre-operational baseline." Analysis results from the indicator samples are compared to both current control sample values and the pre-operational baseline to determine if changes in radioactivity levels are attributable to station operations, or causes such as the Chernobyl accident, Fukushima Daiichi or natural variation.

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

Participation in an Interlaboratory Comparison Program provides an independent 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 that equipment used for radiological environmental monitoring must be able to detect specified minimum Lower Limits of Detection (LLDs). This ensures that analyses are as accurate as possible.

The NRC also mandates a reporting level for certain radionuclides.

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 a percent of the reporting level.Analytical results are reported for all possible radiation exposure pathways to man. These pathways include airborne, water, aquatic, terrestrial, and direct radiation exposure.

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

The 2013 airborne results were similar to previous years. Fallout or natural radioactivity levels remained at levels consistent with past years' results.Water and aquatic exposure pathway samples include precipitation, surface, river and well water, silt and shoreline sediments, and fish. The average tritium activity in surface water for 2013 was 4080 pCi/liter.

No other plant related isotopes were reported in any surface or river water. River water collected from the North Anna River, 5.8 miles downstream of the site had an average tritium level of 4010 pCi/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 natural background.

No plant related isotope was identified in any sample. Shoreline soil, which may provide a direct exposure pathway, indicated the presence of potassium-40 and thorium and uranium decay daughters also at levels consistent with natural levels. No plant related isotope was detected in the indicator or control locations in shoreline soil. No plant related isotope was detected in fish samples from either Lake Anna or the control location, Lake Orange.Soil samples, which are collected every three years from twelve stations, were collected in 2013. Cs- 137 was identified in 10 of 11 indicator samples and the control sample. For the indicator stations the average was 208.9 pCi/Kg while for the control station the average was 329 pCi/Kg. During the preoperational phase Cs-137 was routinely detected and was attributed to fallout. Levels during this phase varied by location and date and ranged from 88 to 1390 pCi/Kg. The average was 645 pCi/kg. The current levels are also varied significantly by location and date. The decrease in the average, and the fact that the averages for the 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.

No plant related radioisotope was detected in any milk samples. Naturally occurring beryllium-7, potassium-40 and radionuclides associated with the uranium and thorium series were detected at environmental levels consistent with historical data. No plant related isotope was detected in any vegetation sample. Low levels of Cs- 137 have been detected intermittently in past years.The direct exposure pathway measures environmental radiation doses by use of thermoluminescent dosimeters (TLDs). TLD results have remained essentially constant over the years.During 2013, as in previous years, operation of the North Anna Power Station and the Independent Spent Fuel Storage Installation (ISFSI) created no adverse environmental effects or health hazards. The maximum total body dose calculated for a hypothetical individual at the station site boundary due to liquid and gaseous effluents released from the station during 2013 was 0.45 millirem.

For reference, this dose may be compared to the 625 millirem average annual exposure to every person in the United States from natural and man-made sources. Natural sources in the environment provide approximately 82% of radiation 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

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 of Fredericksburg, 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 of 1029 megawatts electric (MWe). Unit 1 achieved commercial operation on June 6, 1978 and Unit 2 on December 14, 1980. An independent spent fuel storage facility was licensed for dry cask storage of spent fuel in 1998.The United States Nuclear Regulatory Commission (USNRC) regulations require that nuclear power plants be designed, constructed, and operated to keep levels of radioactive material in effluents to unrestricted areas as low as reasonably achievable (ALARA). To ensure these criteria are met, the operating license for North Anna Power Station includes Technical Specifications, which address the release of radioactive effluents.

In-plant monitoring is used to ensure release limits 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 included in the North Anna Power Station Offsite Dose Calculation Manual (ODCM).North Anna Power Station is responsible for collecting the various indicator and control environmental samples. Global Dosimetry Solutions is utilized for processing 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 to external events, such as cosmic ray bombardment, nuclear weapons test fallout and seasonal variations of naturally occurring radioisotopes.

Data collected prior to station operation is used to indicate the degree of natural variation to be expected.

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

Occasionally samples of environmental media show the presence of man-made isotopes.

As a method of referencing the measured radionuclide concentrations in the sample media to a dose consequence to man, the data is compared to the 7 reporting level concentrations listed in the USNRC Regulatory Guide 4.8 and North Anna's ODCM. These concentrations are based upon the annual dose commitment recommended by 1OCFR50, Appendix I, to meet the criterion of "As Low 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 in those exposure pathways and for those radionuclides that lead to the highest potential radiation exposure of the maximum exposed member of the 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 health and safety of the public.2.2 Sampling and Analysis Program Table 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 those labeled "control."

3. ANALYTICAL RESULTS 3.1 Summary of Results In accordance with the North Anna Offsite Dose Calculation Manual (ODCM), a summary table of the analytical results has been prepared and is presented in Table 3-1. This data is presented in accordance with the format of the USNRC Branch 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 exceeds both 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 the variations in the data explains many aspects that are not evident in the Summary Table because of the basic limitation of data summaries.

3.2 Analytical

Results of 2013 REMP Samples Radiological analyses of environmental media characteristically approach and frequently fall below the detection limits of state-of-the-art measurement methods. The data reported in the following tables are strictly counting statistics.

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

Unless otherwise noted, the overall error (counting, sample size, 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 Minimum Detectable Level (MDL) are statistically valid pieces of data'. For clarity of this report only detectable results are presented.

TBE's analytical methods meet the Lower Limit of Detection (LLD) requirements given in Table 2 of the USNRC Branch Technical Position, "An Acceptable Radiological Environmental Monitoring Program", (November 1979, Revision 1) and the North Anna ODCM.Data are given according to sample type as indicated below.1.

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

In addition to internal quality control measurements performed by each laboratory, they also participate in an Interlaboratory Comparison Program. Participation in this program ensures that independent checks on the precision and accuracy of the measurements of radioactive material in environmental samples are performed.

The results of the Interlaboratory Comparison Programs are provided in Appendix B.The predominant radioactivity detected throughout 2013 was that from external 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 results were variable and are generally at levels higher than plant related radionuclides.

The following is a discussion and summary of the results of the environmental measurements taken during the 2013 reporting period.4.1 Gamma Exposure Rate A thermoluminescent dosimeter (TLD) is an inorganic crystal used to detect ambient 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 at approximately five miles from the station. TLDs are also placed in special interest 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 from nuclear 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 the historical trend of TLD exposure rate measurements.

Control and indicator averages indicate a steady relationship.

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

These TLDs replaced the previously used CaSO4:Dy in Teflon TLDs in January 2001. The 60 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 level of the 32 locations (two badges at each location) was 4.6 mR/standard month with a range of 1.6 to 9.2 mR/standard month. The highest quarterly average reading for any single location was obtained at location NW-29/61.

This value was 7.7 mR/standard month. This location is on site on the north gate of the construction side laydown area. Quarterly and annual TLDs are also located at twelve environmental air sampling stations.

For the eleven indicator locations within 10 miles of the station the average quarterly reading was 3.8 mR/standard month with a range of 1.9 to 6.3 mR/standard month. The average annual reading for these locations was 3.4 mR/standard month with a range from 2.3 to 4.8 mR/standard month. The control location showed a quarterly average of 3.4 mR/standard month with a range of 2.9 to 3.9 mR/standard month. Its annual reading was 3.6 mR/standard month. 10 emergency sector TLDs, which are all located onsite had a quarterly average of 5.4 mR/standard month with EPSP-9/ 10 having the highest quarterly average of 7.8 mR/standard month. Eight other TLDs, designated C-1 thru C-8, which 61 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 2.5 mR/standard month with a range of 1.1 to 3.7 mR/standard month. During the pre-operational period (starting in 1977) the doses were measured between 4.3 and 8.8 mR/standard month.4.2 Airborne Gross Beta Results of the weekly gross beta analyses are presented in Table 3-3. A review of the historical plot in Figure 4-2, indicates gross beta activity levels have remained relatively unchanged.

The drop indicated in 2009 may be a function of a return to the vendor used from 1988 until 2001. This will be monitored in the 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 (see Figure 4-3). This indicates that any station contribution is not measurable.

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

In 1985 weapons testing ceased, and with the exception of the Chernobyl accident in 1986, airborne gross beta results have remained steady. During the preoperational period of July 1, 1974 through March 31, 1978 gross beta activities ranged from a low of 0.005 pCi/m 3 to a high of 0.75 pCi/m 3.0.12 -0.1 E 0.08 -: 0.06 -0 0.04 -0.02 -Control G'ta-24 Indicator Average Pre-op -Required LLD Figure 4-2 Historical Gross Beta in Air Particulates 62 2.50E-02 4L 2.00E-02 1.50E-02 1.OOE-02 5.00E-03 O.OOE+O0 .....r m 0 0-# or 0- z -I Sta 24 -Ul-Indicators Figure 4-3 2013 Gross Beta in Air Particulates (pCi/rm 3)4.3 Airborne Radioiodine Charcoal cartridges are used to collect airborne radioiodine.

Once a week the samples 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 results of samples taken prior to and after the 1986 accident in the Soviet Union at Chernobyl and the effect of the Fukushima Daiichi event.4.4 Air Particulate Gamma The air particulate filters that are utilized for the weekly gross beta analyses are composited by location and analyzed quarterly by gamma spectroscopy.

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

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

The results of these analyses indicate the lack of station 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 no detection of these fission products at any of the indicator or control stations in recent years.4.6 Soil Soil samples, which are collected every three years from twelve stations, were collected in 2013. Cs-137 was identified in 10 of 11 indicator samples and the control sample. For the indicator stations the average was 208.9 pCi/Kg while for the control station the average was 329 pCi/Kg. During the preoperational phase Cs-137 was routinely detected and was attributed to fallout. Levels during this phase varied by location and date and ranged from 88 to 1390 pCi/Kg. The average was 645 pCi/kg. The current levels are also varied significantly by location and date. The decrease in the average, and the fact that the averages for the control location and the indicator locations are similar is indicative of fallout. No other plant related isotopes were identified in Soil samples during 2013.4.7 Precipitation A sample of rain water was collected monthly at on-site station 01A and analyzed 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 in accordance with program requirements.

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

Naturally occurring gamma emitting radioisotopes were detected.

No positive H-3 result was reported.

During the pre-operational period gross beta activity in rain water was expressed in nCi per square meter of the collector surface, thus a direct comparison 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 Milk Analysis of milk samples is generally the most sensitive indicator of fission product existence in the terrestrial environment.

This pathway also shows 64 measurable amounts of nuclear weapons testing fallout. Therefore, this media needs to be evaluated very carefully when trying to determine if there is any plant 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 any isotopes related to the operation of North Anna. In years past, Cs-137 has been detected sporadically.

These occurrences were attributed to residual global 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 for strontium-89 and strontium-90.

Neither Sr-89 nor Sr-90 was detected.

Sr-90 has 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-90 showing a continuous decline. It should be noted that strontium-90 is not a part of station effluents.

Its detection is the product of nuclear weapons testing fallout. This conclusion can be made based upon the fact that Sr-89 and Sr-90 have not been detected in gaseous effluents released from the station in many years, and the trend of consistent declining levels since the pre-operational period.4.9 Food Products and Vegetation Food/vegetation samples were collected from five locations and analyzed by gamma spectroscopy.

The results of the analyses are presented in Table 3-9.Low levels of Cs- 137, attributable to fallout, have been seen periodically in vegetation samples. As expected, naturally occurring potassium-40 and cosmogenic beryllium-7 were detected in most samples, and thorium-228 and other natural products, including Bi-214, were detected in some samples. No plant related isotopes were identified in any Vegetation sample during 2013.4.10 Well Water Water was sampled quarterly from the onsite well at the metrology laboratory.

These samples were analyzed for gamma radiation and for tritium. The second quarter sample was analyzed by vendor for Sr-89, Sr-90, H-3, 1-131, and gamma emitters.

The results of these analyses are presented in Table 3-10. No plant related isotopes were detected.

No gamma emitting isotopes were detected during the pre-operational period.65 4.11 River Water Samples of water from the North Anna River were collected monthly. The analyses are presented in Table 3-11. All monthly samples are analyzed by gamma spectroscopy.

The monthly samples were composited quarterly and analyzed for tritium. Additionally, the second quarter samples are analyzed for strontium-89 and strontium-90 in accordance with program requirements.

There has been no detection of these fission products at any of the indicator or control stations in recent years.No gamma emitting radioisotopes were positively identified in any of the samples. There was no measured activity of strontium-89 or strontium-90.

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

These levels are comparable to those observed in previous years, see Figure 4-4. No river water samples were collected during the pre-operational period.River Water 4500 4500 4000 4000 3500 4 3500-J 3000 3000 4&2500 2500 --$-tritium 2000 2000 --I-Req LLD 1500 1500 1000 1000 Figure 4-4Tritium in River water 66 4.12 Surface Water Samples of surface water were collected monthly from two stations, an indicator station located at the discharge lagoon and a control station located 12.9 miles WNW. The samples were analyzed by gamma spectroscopy and for iodine-131 by radiochemical separation.

A quarterly composite from each station was prepared and analyzed for tritium. Additionally, the second quarter samples are analyzed for strontium-89 and strontium-90.

There has been no positive indication of these fission products at any of the indicator or control stations in recent years. The results are presented in Table 3-12.No non-naturally occurring gamma emitting radioisotopes, including iodine were detected in any of the samples. No tritium was detected at the control location.

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

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

Levels.measured at the indicator location (Station 8) are comparable to those measured since 1986, see Figure 4-5. During the pre-operational period tritium was measured in several samples with concentrations between 90 and 250 pCi/liter.

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

The October samples were analyzed for strontium-89 and strontium-90.

The results are presented in Table 3-13.No plant related isotopes were detected in 2013. The detection of Cs-137 in bottom sediment is historically common with positive indications usually apparent in both indicator and control samples. The detection of Cs-137 is the 68 result of accumulation and runoff into the lake of residual weapons testing fallout; its global presence has been well documented.

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

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

Neither Strontium-89 nor Strontium-90 was detected in any samples of aquatic sediment/silt in 2013. Strontium-90 has been detected occasionally in the past at both the indicator and control locations and is attributable to fallout from past bomb tests. A number of naturally occurring radioisotopes were detected in these samples at background levels.1600 -Station-1400 8 1200.91000 9 800.600 Control 400 -Sta-09A 200 9 20--Station-o~ Cc W o M -' Z LCi)W L -) Z M M O0 5C Figure 4-6 Cs-137 in Sediment/Silt 4.14 Shoreline Soil Shoreline soil/sediment, unlike bottom sediment, may provide a direct dose to humans. Buildup of radioisotopes along the shoreline may provide a source of direct 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 October sample was analyzed for strontium-89 and strontium-90.

The results are presented in Table 3-14.Naturally occurring radioisotopes were detected at concentrations equivalent to normal background activities.

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

Strontium-90 is often detected in this media, however as discussed previously, the presence of Sr-90 and Cs-137 is 69 attributed to accumulation of residual global fallout from past atmospheric weapons testing.4.15 Fish Four sample sets of fish, two from Lake Anna and two from the control station, Lake Orange, were collected during 2013 and analyzed by gamma spectroscopy.

Each sample set consisted of a sample of game species and a sample of bottom-dwelling species, which were analyzed separately.

The results are presented in Table 3-15. Naturally occurring K-40 was detected in all samples. No plant related isotopes were detected.

Cs- 137 was measured in pre-operational environmental fish samples.70

SUMMARY

OF INTERLABORATORY COMPARISONS YEAR 2013 INTRODUCTION This appendix covers the Intercomparison Program of the Teledyne Brown Engineering

-Environmental Services as required by technical specifications for the Radiological Environmental Monitoring Program (REMP). TBE uses QA/QC samples provided by Eckeri & Zeigler Analytics, Inc, DOE's Mixed Analyte 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 of sample number, matrices, and nuclides.

This includes: 77 E & Z Analytics:

Milk for gamma emitters, Iodine-131, Fe-55, Sr-89 and Sr-90 analyses once per quarter.Air particulate for gamma emitters once per quarter Charcoal for 1-131 once per quarter ERA Water for tritium, gamma, Iodine- 131, Sr-89, Sr-90, gross alpha and beta during the 2nd and 4th quarters.Water for natural uranium during the 2nd quarter DOE Water and soil for gamma, Iodine-131, U-233/234, U-238, transuranics, tritium, Fe-55, Ni-63, Sr-90 and Tc-99 analyses during the 1st quarter.Water for gross alpha and beta during the 1 st and 3rd quarters.Air particulates and vegetation for gamma, Iodine-131, U-233/234, U-238, transuranics, Sr-90 analyses during the .1st and 3rd quarters.Air filter for gross alpha and beta analyses during the 1st and 3rd quarters.78 RESULTS Interlaboratory comparison program results are evaluated using TBE's criterion.

Any sample analysis result that does not pass the criteria is investigated 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 the specified acceptance criteria.

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

[two low warning in a row]) did not meet the specified acceptance criteria or internal QA requirements for the following reason: 1. Teledyne Brown Engineering's Analytics September 2013 Sr-89 in milk result of 63.9 pCi/L was lower than the known value of 96.0 pCi/L. The failure was a result of analyst error and was specific to the Analytics sample. Client samples for the associated time period were evaluated and no client samples were affected by this failure. NCR 13-15 2. Teledyne Brown Engineering's Analytics September 2013 Sr-90 in milk result of 8.88 pCi/L was lower than the known value of 13.2 pCi/L. The failure was a result of analyst error and was specific to the Analytics sample. Client samples for the associated time period were evaluated and no client samples were affected by this failure. NCR 13-15 3. & 4. Teledyne Brown Engineering's MAPEP September 2013 Co-57 and Zn-65 in soil were evaluated as failing the false positive 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 reported as detected nuclides to a client. MAPEP does not allow laboratories to put in qualifiers for the submitted data nor"less than" results. MAPEP evaluates results based on the relationship between the activity and the uncertainty.

MAPEP spiked the soil sample with an extremely large concentration of Eu- 152, which was identified by the gamma software as an interfering nuclide, resulting in forced activity results that were evaluated by MAPEP as detected Co-57 and Zn-65. No client samples were affected by these failures.NCR 13-14 5. Teledyne Brown Engineering's MAPEP September 2013 Sr-90 in soil result of 664 Bq/kg was higher than the known value of 460 Bq/kg, exceeding the upper control limit of 598 Bq/kg. An incorrect Sr-90 result was entered into the MAPEP database.

The correct Sr-90 activity of 322 Bq/kg would have been evaluated as acceptable with warning. No client samples were affected by this failure. NCR 13-14 6. Teledyne Brown Engineering's MAPEP September 2013 Cs-134 in air particulate activity of -0.570 Bq/sample was evaluated as a failed false positive test, based on MAPEP's evaluation of the result as a significant negative value at 3 standard deviations.

A negative number would never have been reported as a detected nuclide to a client, therefore no client samples were affected by this failure. NCR 13-14 7. Teledyne Brown Engineering's MAPEP September 2013 Sr-90 in vegetation result was investigated due to two low warnings in a row. It appears the September sample was double 80 spiked with carrier, resulting in a low activity.

With a recovery of around 50% lower, the Sr-90 result would have fallen within the acceptance range. No client samples were affected by this issue. NCR 13-14 A 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 known values supplied by the providers; pass or fail criteria.81 4 ANALYTICS ENVIRONMENTAL RADIOACTIVITY CROSS CHECK PROGRAM TELEDYNE BROWN ENGINEERING ENVIRONMENTAL SERVICES Identification Reported Known Ratio (c)Month/Year Number Matrix Nuclide Units Value (a) Value (b) TBE/Analytics Evaluation (d)March 2013 E10477 E10478 E10480 Milk Milk AP Sr-89 pCi/L 120 Sr-90 pCi/L 9.21 1-131 Ce-141 Cr-51 Cs-134 Cs-137 Co-58 Mn-54 Fe-59 Zn-65 Co-60 Ce-141 Cr-51 Cs-134 Cs-137 Co-58 Mn-54 Fe-59 Zn-65 Co-60 pCi/L pCi/L pCi/L pCi/L pCi/L pCi/L pCi/L pCi/L pCi/L pCi/L pCi pCi pCi pCi pCi pCi pCi pCi pCi 87.1 186 463 201 262 200 215 266 311 384 95.3 264 123 142 112 115 139 163 212 99.7 11.0 100 187 472 214 266 208 208 252 301 400 95.6 241 109 136 106 106 129 153 204 92.6 1890 95.0 17.0 95.5 90.4 250 125 151 94.0 1.20 0.84 0.87 0.99 0.98 0.94 0.98 0.96 1.03 1.06 1.03 0.96 1.00 1.10 1.13 1.04 1.06 1.08 1.08 1.07 1.04 0.97 0.97 1.16 0.93 0.97 0.92 1.01 0.94 0.95 0.93 A A A A A A A A A A A A A A A A A A A A A A A A A A A A A A A El 0479 E10481 June 2013 E10564 E10545 Charcoal 1-131 pCi 90.1 Water Milk Milk Fe-55 pCi/L 1840 Sr-89 pCi/L 110 Sr-90 pCi/L 15.8 1-131 Ce-141 Cr-51 Cs-1 34 Cs-1 37 Co-58 pCi/L pCi/L pCi/L pCi/L pCi/L pCi/L 92.6 83.1 253 118 143 87.1 82 Mn-54 pCi/L 171 172 0.99 A Fe-59 pCi/L 125 120 1.04 A Zn-65 pCi/L 220 217 1.01 A Co-60 pCi/L 169 175 0.97 A E10547 AP Ce-141 pCi 56.8 56.7 1.00 A Cr-51 pCi 168 157 1.07 A Cs-134 pCi 85.2 78.4 1.09 A Cs-137 pCi 101 94.6 1.07 A Co-58 pCi 62.7 58.9 1.06 A Mn-54 pCi 125 108 1.16 A Fe-59 pCi 85.7 75.0 1.14 A Zn-65 pCi 169 136 1.24 W Co-60 pCi 116 110 1.05 A E10546 Charcoal 1-131 pCi 86.5 89.7 0.96 A 83 ANALYTICS ENVIRONMENTAL RADIOACTIVITY CROSS CHECK PROGRAM TELEDYNE BROWN ENGINEERING ENVIRONMENTAL SERVICES Identification Reported Known Ratio (c)Value Month/Year Number Matrix Nuclide Units Value (a) (b) TBE/Analytics Evaluation (d)June 2013 September 2013 E10549 E10646 E10647 Water Fe-55 pCi/L 1610 Milk Milk Sr-89 pCi/L 63.9 Sr-90 pCi/L 8.88 1-131 Ce-141 Cr-51 Cs-1 34 Cs-1 37 Co-58 Mn-54 Fe-59 Zn-65 Co-60 pCi/L pCi/L pCi/L pCi/L pCi/L pCi/L pCi/L pCi/L pCi/L pCi/L 93.9 272 150 125 105 138 125 264 187 208 143 106 97.0 116 98.6 219 166 E10672 E10648 E10673 E10774 E10775 AP Ce-141 Cr-51 Cs-134 Cs-137 Co-58 Mn-54 Fe-59 Zn-65 Co-60 pCi pCi pCi pCi pCi pCi pCi pCi pCi 1610 96.0 13.2 98.3 277 172 131 108 139 130 266 196 223 139 105 86.5 112 105 214 158 71.7 1690 93.8 12.9 96.1 110 297 142 0.67 0.67 0.96 0.98 0.87 0.95 0.97 0.99 0.96 0.99 0.95 N (1)N (1)A NA (2)A A A A A A A A 1.00 A Charcoal 1-131 pCi 76.3 Water Fe-55 pCi/L 1790 0.93 1.03 1.01 1.12 1.04 0.94 1.02 1.05 1.06 1.06 1.04 1.03 0.93 0.91 1.00 0.91 NA (2)A A A A A A A A December 2013 Milk Milk Sr-89 pCi/L 97.3 Sr-90 pCi/L 13.3 A A A A A A A A 1-131 Ce-141 Cr-51 Cs-134 pCi/L pCi/L pCi/L pCi/L 89.7 99.8 297 129 84 I Cs-137 pCi/L 126 126 1.00 A Co-58 pCi/L 116 112 1.04 A Mn-54 pCi/L 167 168 0.99 A Fe-59 pCi/L 117 110 1.06 A Zn-65 pCi/L 757 741 1.02 A Co-60 pCi/L 141 147 0.96 A E10777 AP Ce-141 pCi 85.1 88.0 0.97 A Cr-51 pCi 278 238 1.17 A Cs-134 pCi 123 114 1.08 A Cs-137 pCi 102 101 1.01 A Co-58 pCi 84.4 89.9 0.94 A Mn-54 pCi 132 135 0.98 A Fe-59 pCi 101 88.3 1.14 A Zn-65 pCi 506 595 0.85 A Co-60 pCi 118 118 1.00 A ANALYTICS ENVIRONMENTAL RADIOACTIVITY CROSS CHECK PROGRAM TELEDYNE BROWN ENGINEERING ENVIRONMENTAL SERVICES Identification Reported Known Ratio (c)Month/Year Number Matrix Nuclide Units Value (a) Value (b) TBE/Analytics Evaluation (d)December 2013 E10776 Charcoal 1-131 pCi 84.7 80.5 1.05 A E10778 Water Fe-55 pCi/L 2010 1910 1.05 A (1) Milk, Sr-89/90 -The failure was due to analyst error.
