Re: State of Utah Radioactive Material License No. UT1900479
White Mesa Mill, Blanding, Utah
Addendum to the Semi-Annual Effluent Monitoring Report for Period
January 1,2013 through June 30,2013
Dear Mr. Lundberg:
This document is an addendum to the semi-annual effluent report for the period January through June,
2013 (the "SAER") which was submitted to the Utah Department of Environmental Quality Division of
Radiation Control on August 29, 2013.
As explained in the SAER, due to the operational conditions in the 1st quarter of 2013, the 2nd quarter
samples were taken very early in the quarter, which resulted in a miscommunication with the analytical
laboratory. The yellowcake packaging baghouse was analyzed for only U-nat, as is required for the first
quarterly sample, excluding the analyses for Th-230, Ra-226, and Pb-210 as is routinely performed for the
second quarter samples. EFRI's QA Manager identified the issue, noted that the sample were still within
the method specified holding time, and requested the laboratory analyze the samples for all required
analyses. As a result, all required analyses for the second quarter samples have been completed. However,
the laboratory was unable to deliver the Th-230, Ra-226, and Pb-210 results for the yellowcake packaging
baghouse in time to be included in the initial SAER submitted on August 29, 2013. The purpose of this
addendum is to amend the SAER to include the Th-230, Ra-226, and Pb-210 results for the second
quarter.

ADDENDUM
WHITE MESA URANIUM MILL
SEMI-ANNUAL EFFLUENT REPORT, JANUARY THROUGH JUNE 2013
1. INTRODUCTION
The White Mesa Mill (the "Mill") has established monitoring programs to evaluate compliance
with effluent limitations and to assess the potential for release of radioactive material into the
local environment. These monitoring programs were developed and implemented at the time of
Mill construction, operated with appropriate adaptation over time, and are consistent with the
Mill's State of Utah Radioactive Materials License No. UT1900479 (the "License") and
guidelines developed by the United States Nuclear Regulatory Commission ("NRC") (NRC
Regulatory Guide 4.14, Radiological Effluent and Environmental Monitoring at Uranium Mills-
Rev. 1, ML003739941), 1980).
The Mill's semi-annual effluent reports provide the results of the specific monitoring and
sampling activities that were undertaken during the subject reporting period.
This document is an addendum to the semi-annual effluent report for the period January through
June, 2013 (the "SAER") which was submitted to the Utah Department of Environmental
Quality Division of Radiation Control on August 29,2013.
As explained in the SAER, due to the operational conditions in the 1st quarter of 2013, the 2nd
quarter samples were taken very early in the quarter, which resulted in a miscommunication with
the analytical laboratory. The yellowcake packaging baghouse samples were analyzed for only
U-nat, as is required for the first quarterly sample, excluding the analyses for Th-230, Ra-226,
and Pb-210 as is routinely performed for the second quarter samples. EFRI's QA Manager
identified the issue, noted that the sample were still within the method specified holding time,
and requested the laboratory analyze the samples for all required analyses. As a result, all
required analyses for the second quarter samples have been completed. However, the laboratory
was unable to deliver the Th-230, Ra-226, and Pb-210 results for the yellowcake packaging
baghouse in time to be included in the initial SAER submitted on August 29, 2013. The purpose
of this addendum is to amend the SAER to include the Th-230, Ra-226, and Pb-210 results for
the second quarter.

INTRODUCTION
Test Purpose
This test project was conducted to determine the total radionuclide emissions from the South
Yellow Cake Scrubber, Yellow Cake Dryer Baghouse, and Grizzly Baghouse exhausts in terms
of Curies per dry standard cubic foot (Ci/dscf).
These tests were for U-Nat and Th-230 on the Grizzly Baghouse and U-Nat, Th-230, Ra-226,
and Pb-210 on the South Yellow Cake Scrubber and Yellow Cake Dryer Baghouse.
Test Location and Type of Process
Energy Fuels Resources is located about 5 miles south of Blanding, Utah. Uranium ore is
processed into yellow cake, which is shipped to other facilities for additional processing. There
are two yellow cake dryers with individual scrubbers. Both dryer enclosures discharge into the
Dryer Baghouse. The Packaging enclosure also discharges into the Dryer Baghouse. The South
Yell ow Cake (NYC) dryer was the only operating dryer at the time of the test. The North
Yell ow Cake Dryer was not operating at the time of the test. The Grizzly Baghouse serve as the
main dust control device for the raw ore unloading and conveying to the processing building.
Stack schematics are shown as Figures I though 3 in Appendix D.
Test Dates
The first test run on the SYC Scrubber was completed April3, 2013. The second test run was
completed April 4, 2013.
One test run was completed on the Yellow Cake Dryer Baghouse April4, 2013.
One run was completed on the Grizzly Baghouse June 5-6, 2013.
Pollutants Tested and Methods Applied
The tests were a determination ofradionuclide emissions in accordance with EPA Method 5/114.
Test run filters and front wash residues were sent to Test America located in Richland,
Washington for radionuclide analysis.

Process Data
The process was operated according to standard procedures. All pertinent process data was
available for recording by agency personnel. Scrubber water flow, pressure drop readings (11p)
were recorded and are found in Appendix D. The Dryer Baghouse pressure drop readings (11p)
were recorded and are found on the test run sheets. Production data is retrained by Energy Fuels
Resources.
Description of Collected Samples
The test filters for the South Yell ow Cake Scrubber were heavily covered with an off-white
colored particulate. The front washes were clear in appearance.
The test filters for the Yell ow Cake Dryer Baghouse were lightly colored with a tan colored
particulate. The front wash was clear in appearance.
The test filters for the Grizzly Baghouse were had no visible particulate. The front wash was
clear in appearance.
Discussion of Errors or Irregularities
3
The sample analyses for the SYC and Dryer Baghouse were initially completed for U-Nat and not
the other radionuclides. After conferring with Energy Fuels Resources representatives and
approximately three weeks after the initial sample analyses, Test American was contacted to see
if the samples could be analyzed for Th-230, Pb-210 and Ra-226. Test American indicated that
there was sufficient sample to run the additional analyses. A separate laboratory report from Test
America was completed for the additional analyses.
Because of a communication error in requesting the additional analyses, the Dryer Baghouse
samples were not analyzed for Th-230, Pb-210, and Ra-226 during the re-analysis of the samples.
Test American was again contacted to see if the Dryer Baghouse samples could be analyzed for
Th-230, Pb-21 0 and Ra-226. Test American indicated that there was sufficient sample to run the
additional analyses. Another laboratory report from Test America was completed for the
additional analyses.
Percent Isokinetic Samplin~:
Each of the tests were isokinetic within the ±10% of 100% criterion specified in the Federal
Register. They also meet the Utah State Department ofEnvironmental Quality, Division of Air
Quality specification of isokinetic sampling point by point. Isokinetic values for each test run are
presented in Table II.

SAMPLING AND ANALYSIS PROCEDURES
Sampling Port Location
The inside diameter of the South Yellow Cake Scrubber stack is 12.75 inches. The two, four-inch
diameter sample port are located 28.24 diameters (30 feet) downstream from the last disturbance
and 6.59 diameters (7 feet) upstream from the next disturbance. Figure I in Appendix D is a
schematic of the stack.
The inside diameter of the Yell ow Cake Dryer Baghouse stack is I6.0 inches. The two, four-inch
diameter sample ports are located 28.38 diameters (454 inches) downstream from the last
disturbance and 3.56 diameters (57 inches) upstream from the next disturbance. The sample port
locations are depicted in Figure 2 in Appendix D.
The inside diameter of the Grizzly Baghouse stack is I8.75 inches. There are two, three-inch
diameter sample ports located 2.56 diameters (48 inches) downstream from the last disturbance
and I.3I diameters (24.5 inches) upstream from the next disturbance. The sample port locations
are depicted in Figure 3 in Appendix D.
Sampling Point Location
Table III shows the distance of each sampling point from the inside wall according to EPA
Method I. Each point is marked and identified with a wrapping of glass tape and numbered.
These points are determined by measuring the distance from the inside wall.

Uncertainty Estimation
TestAmerica Richland has adopted the internationally accepted approach to estimating
uncertainties described in "NIST Teclmical Note 1297, 1994 Edition", The approach, "Law of Propagation
of Errors", involves the identification of all variables in an analytical method which are used to derive a
result. These variables are related to the analytical result (R) by some functional relationship, R = constants * f(x,y,z, ... ). The components (x,y,z) are evaluated to determine their contribution to the overall method
uncertainty. The individual component unce1tainties (ui) are then combined using a statistical model that
provides the most probable overall uncertainty value. All component uncertainties are categorized as type
A, evaluated by statistical methods, or type B, evaluated by other means. Uncertainties not included in the
components, such as sample homogeneity, are combined with the component uncertainty as the square root
of the sum-of-the-squares of the individual uncertainties. The uncertainty associ11ted with the derived result
is the combined uncertainty (uc) multiplied by the coverage factor (1,2, Ol' 3).
When three or more sample replicates are used to derive the analytical result, the type A
uncertainty is the standard deviation of the mean value (S/? n), where Sis the standard deviation of the
derived results. The type B uncertainties are all other random or non-random components that are not
included in the standard deviation.
The derivation of the general "Law of Propagation of Errors" equations and specific example are
available on request.

Report Definitions
An agr<!Cd upon activity lc\teluscd to rrigger some ncrion when the linn! result is greater than or equal to !he Acllon
Level. Often the Action Level is rolarcd to the Decision Limit.
The QC preparation batch number that relates laboratory samples to QC samples that were prepared and analyzed
together.
Defined by the equation (Result/Expected)-! as defined by ANSI N 13.3 0.
Chain of Custody Number assigned by the Client or TestAmerica.
Poisson counting statistics of the gross sample count and background. The uncertainty is absolute. and in the same
units as the result. For Liquid Scintillation Counting (LSC) the batch blank count is the background.
All known uncertain!"ies associated with the preparation and analysis ofthe sample are propagated to give a measure
of the uncertainty associated with the result, u. the combined uncertainty. The uncertainty is absolute and in the
same units as the result
The coverage factor defines the width of the confidence interval, 1, 2 or 3 standard deviations.
Contractual Required Detection Limit as defined in the Client's Statement Of Work or TestAmerica "default"
nominal detection limit. Often referred to the reporting level (RL)
Decision Level based on instrument background or blank, adjusted by the Efficiency, Chemical Yield, and Volume
associated with the sample. The Type I error probability is approximately 5%. Lc=(I.645 *
Sqrt(2*(BkgrndCnt!BkgmdCntMin)/SCntMin)) * (ConvFcti(Eff*Yld* Abn*Vol) * lngrFct). For LSC methods the
batch blank is used as a measure of the background variability. Lc cannot be calculated when the background count
is zero.
The number assigned by the UMS software to track samples received on the same day for a given client. The
sample number is a sequential number assigned to each sample in the Lot.
Detection Level based on instrument background or blank, adjusted by the Efficiency, Chemical Yield, and Volume
with a Type I and II error probability of Rppr·oximat¢1y'5%. MDC= (4.65 *
Sqrt((llkgmdCnr/BkgmdG.'nlMin)/ Cnt'Min) I· 2. 71/SCniMin) t (ConvPctJ(liD' • Yld • Abn • Vol) * IngrFct). For
LSC methods the batch blank is used as a mciiSlH'c oflhc background vnrlnbility.

The U-234 result divided by the U-238 result. The U-234/U-238 ratio for natural uranium in NIST SRM 4321 Cis
1.038.
Ratio ofthe Result to the MDC. A value greater than 1 may indicate activity above background at a high level of
confidence. Caution should be used when applying this factor and it should be used in concert with the qualifiers
associated with the result.
Ratio of the Result to the Total Uncl)rtainty. lfthe uncertainty has a coverage factor of 2 a value greater than I may
indicate activity above background at approximately the 95% level of confidence assuming a two-sided confidence
interval. Caution should be used when applying this factor and it should be used in concert with the qualifiers
associated with the result.
Sample Identifier used by the report system. The number is based upon the first five digits of the Work Order
Nmnber.
The equation Replicate Error Ratio= (S-D)/[ sqrt(TPUs2 + TPUd2)] as defined by ICPT BOA where S is the original
sample result, D i"s the result of the duplicate, TPUs is the total uncertainty of the original sample and TPUd is the
total uncertainty of the duplicate sample.
Sample Delivery Group Number assigned by the Client or assigned by TcstAmerica upon sample receipt.

IV. Quality Control
The analytical result for each analysis perfonned includes a minimum of one laboratory control sample
(LCS), and one reagent blank sample analysis. Any exceptions have been noted in the "Comments"
section.
V. Comments
Alpha Spectroscopy
Thorium-228, 230, 232
The blank result ofTh-230 has a result above the achieved MDA; suspect some tailing from the Th-229
tracer. The FWHM is elevated, due to the typical and expected tailing from the Th-229 tracer. The
achieved MDA ofthe samples exceeds the detection limit due insufficient sample volume. There is no
sample volume remaining for re-analysis. Data is reported. Except as noted, the LCS, batch blank and
sample results are within acceptance limits.
Gas Proportional Counting
Pb-210
The achieved MDA of the batch exceeds the detection limit from reduced aliquot sizes taken due to
historical process knowledge. The sample activities exceed the MDAs. Data is accepted. Except as
noted, the LCS, batch blank and sample results are within acceptance limits.
Alpha Scintillation
Radium-226
The achieved MDA of the samples exceeds the detection limit due insufficient sample volume. There is
no sample volume remaining for re-analysis. Data is reported. Except as noted, the LCS, batch blank and
sample results are within acceptance limits.
I certify that this Certificate of Analysis is in compliance with the SOW and/or NELAC, both technically

Uncertainty Estimation
TestAmerica Richland has adopted the internationally accepted approach to estimating
uncertainties described in "NIST Technical Note 1297, 1994 Edition". The approach, "Law of Propagation
of Errors", involves the identification of all variables in an analytical method which are used to derive a
result. These variables are related to the analytical result (R) by some functional relationship, R = constants
* f(x,y,z, ... ). The components (x,y,z) are evaluated to determine their contribution to the overall method
uncertainty. The individual component uncertainties (u;) are then combined using a statistical model that
provides the most probable overall uncertainty value. All component uncertainties are categorized as type
A, evaluated by statistical methods, or type B, evaluated by other means. Uncertainties not included in the
components, such as sample homogeneity, are combined with the component uncertainty as the square root
of the sum-of-the-squares of the individual uncertainties. The uncertainty associated with the derived result
is the combined uncertainty (u0) multiplied by the coverage factor (1,2, or 3).
When three or more sample replicates are used to derive the analytical result, the type A
uncertainty is the standard deviation of the mean value (S/?n), where Sis the standard deviation of the
derived results. The type B uncertainties are all other random or non-random components that are not
included in the standard deviation.
The derivation of the general "Law of Propagation of Errors" equations and specific example are
available on request.

Report Definitions
An ogpeed upon octi fly level used to trigger some action when the final result is greater thun or equal to the Action
Level. Often the Action Level is related to the Decision Limit.
The QC preparation batch number that relates laboratory samples to QC samples that were prepared and analyzed
together.
Defined by the equation (Result/Expected)-! as defined by ANSI Nl3.30.
Chain of Custody Number assigned by the Client or TestAmerica.
Poisson counting statistics of the gross sample count and background. The uncertainty is absolute and in the same
units as the result. For Liquid Scintillation Counting (LSC) the batch blank count is the background.
All known uncertainties associated with the preparation and analysis of the sample are propagated to give a measure
of the uncertainty associated with the result, Uc the combined uncertainty. The uncertainty is absolute and in the
same units as the result.
The coverage factor defines the width of the confidence interval, 1, 2 or 3 standard deviations.
Contractual Required Detection Limit as defined in the Client's Statement Of Work or TestAmerica "default"
nominal detection limit. Often referred to the reporting level (RL)
Decision Level based on instrument background or blank, adjusted by the Efficiency, Chemical Yield, and Volume
associated with the sample. The Type I error probability is approximately 5%. Lc=(1.645 *
Sqrt(2*(BkgmdCnt/BkgmdCntMin)/SCntMin)) * (ConvFct/(Eff*Yld*Abn*Vol) * IngrFct). For LSC methods the
batch blank is used as a measure of the background variability. Lc cannot be calculated when the background count
is zero.
The number assigned by the LIMS software to track samples received on the same day for a given client. The
sample number is a sequential number assigned to each sample in the Lot.
Detection Level based on instrument background or blank, adjusted by the Efficiency, Chemical Yield, and Volume
with a Type I and II error probability of approximately 5%. MDC = (4.65 *
Sqrt((BkgmdCnt/BkgrndCntMin)/SCntMin) + 2.71 /SCntMin) * (Convfct/(Eff* Yld * Abn *Vol)* Ingrfct). For
LSC methods the batch blank is used as a measure of the background variability.
The instrument identifier associated with the analysis of the sample aliquot.
The U-234 result divided by the U-238 result. The U-234/U-238 ratio for natural uranium in NIST SRM 4321C is
1.038.
Ratio of the Result to the MDC. A value greater than 1 may indicate activity above background at a high level of
confidence. Caution should be used when applying this factor and it should be used in concert with the qualifiers
associated with the result.
Ratio of the Result to the Total Uncertainty. If the uncertainty has a coverage factor of2 a value greater than 1 may
indicate activity above background at approximately the 95% level of confidence assuming a two-sided confidence
interval. Caution should be used when applying this factor and it should be used in concert with the qualifiers
associated with the result.
Sample Identifier used by the report system. The number is based upon the first five digits of the Work Order
Number.
The equation Replicate Error Ratio= (S-D)/[sqrt(TPUs2+ TPUd2)] as defined by ICPT BOA where Sis the original
sample result, D is the result of the duplicate, TPUs is the total uncertainty of the original sample and TPUd is the
total uncertainty of the duplicate sample.
Sample Delivery Group Number assigned by the Client or assigned by TestAmerica upon sample receipt.
The sum of the reported alpha spec results for tests derived from the same sample excluding duplicate result where
the results are in the same units.
The LIMS software assign test specific identifier.
The recovery of the tracer added to the sample such as Pu-242 used to trace a Pu-239/40 method.

IV. Quality Control
The analytical result for each analysis performed includes a minimum of one laboratory control sample
(LCS), and one reagent blank sample analysis. Any exceptions have been noted in the "Comments"
section.
V. Comments
Alpha Spectroscopy
Thorium-228, 230, 232
The blank result ofTh-230 has a result above the achieved MDA; suspect some tailing from the Th-229
tracer. The FWHM is elevated, due to the typical and expected tailing from the Th-229 tracer. The
achieved MDA of the samples exceeds the detection limit due insufficient sample volume. There is no
sample volume remaining for re-analysis. Data is reported. Except as noted, the LCS, batch blank and
sample results are within acceptance limits.
Uranium-234, 235, 238
The achieved MDA of the batch exceeds the detection limit from reduced aliquot sizes taken due to
historical process knowledge. The sample activities exceed the MDAs. Data is accepted. Except as
noted, the LCS, batch blank and sample results are within acceptance limits.
I certify that this Certificate of Analysis is in compliance with the SOW and/or NELAC, both technically
and for completeness, for other than the conditions detailed above. The Laboratory Manager or a
designee, as verified by the following signature has authorized release of the data contained in this hard

Uncertainty Estimation
TestAmerica Richland has adopted the internationally accepted approach to estimating
uncertainties described in "NIST Technical Note 1297, 1994 Edition". The approach, "Law of Propagation
of Errors", involves the identification of all variables in an analytical method which are used to derive a
result. These variables are related to the analytical result (R) by some functional relationship, R = constants
* f(x,y,z, ... ). The components (x,y,z) are evaluated to determine their contribution to the overall method
uncertainty. The individual component uncertainties (u;) are then combined using a statistical model that
provides the most probable overall uncertainty value. All component uncertainties are categorized as type
A, evaluated by statistical methods, or type B, evaluated by other means. Uncertainties not included in the
components, such as sample homogeneity, are combined with the component uncertainty as the square root
of the sum-of-the-squares ofthe individual uncertainties. The uncertainty associated with the derived result
is the combined uncertainty (uc) multiplied by the coverage factor (1 ,2, or 3).
When three or more sample replicates are used to derive the analytical result, the type A
uncertainty is the standard deviation of the mean value (S/?n), where Sis the standard deviation of the
derived results. The type B uncertainties are all other random or non-random components that are not
included in the standard deviation.
The derivation of the general "Law of Propagation of Errors" equations and specific example are
available on request.

Re ort Definitions
An agreed upon activity level used to trigger some action when the final result is greater than or equal to the Action
Level. Often the Action Level is related to the Decision Limit.
The QC preparation batch number that relates laboratory samples to QC samples that were prepared and analyzed
together.
Defined by the equation (Result/Expected)-! as defined by ANSI Nl3.30.
Chain of Custody Number assigned by the Client or TestAmerica.
Poisson counting statistics of the gross sample count and background. The uncertainty is absolute and in the same
units as the result. For Liquid Scintillation Counting (LSC) the batch blank count is the background.
All known uncertainties associated with the preparation and analysis of the sample are propagated to give a measure
of the uncertainty associated with the result, Uc the combined uncertainty. The uncertainty is absolute and in the
same units as the result.
The coverage factor defines the width of the confidence interval, I, 2 or 3 standard deviations.
Contractual Required Detection Limit as defined in the Client's Statement Of Work or TestAmerica "default"
nominal detection limit. Often referred to the reporting level (RL)
Decision Level based on instrument background or blank, adjusted by the Efficiency, Chemical Yield, and Volume
associated with the sample. The Type I error probability is approximately 5%. Lc=(I.645 *
Sqrt(2*(BkgrndCnt/BkgrndCntMin)/SCntMin)) * (ConvFct/(Eff*Yld*Abn*Vol) * IngrFct). For LSC methods the
batch blank is used as a measure of the background variability. Lc cannot be calculated when the background count
is zero.
The number assigned by the LIMS software to track samples received on the same day for a given client. The
sample number is a sequential number assigned to each sample in the Lot.
Detection Level based on instrument background or blank, adjusted by the Efficiency, Chemical Yield, and Volume
with a Type I and II error probability of approximately 5%. MDC = (4.65 *
Sqrt((BkgrndCnt/BkgrndCntMin)/SCntMin) + 2.71 /SCntMin) * (ConvFct/(Eff* Yld * Abn *Vol)* IngrFct). For
LSC methods the batch blank is used as a measure of the background variability.
The instrument identifier associated with the analysis of the sample aliquot.
The U-234 result divided by the U-238 result. The U-234/U-238 ratio for natural uranium in NIST SRM 4321 C is
1.038.
Ratio of the Result to the MDC. A value greater than I may indicate activity above background at a high level of
confidence. Caution should be used when applying this factor and it should be used in concert with the qualifiers
associated with the result.
Ratio ofthe Result to the Total Uncertainty. If the uncertainty has a coverage factor of2 a value greater than I may
indicate activity above background at approximately the 95% level of confidence assuming a two-sided confidence
interval. Caution should be used when applying this factor and it should be used in concert with the qualifiers
associated with the result.
Sample Identifier used by the report system. The number is based upon the first five digits of the Work Order
Number.
The equation Replicate Error Ratio= (S-D)/[sqrt(TPUs2+ TPUd2)] as defined by ICPT BOA where Sis the original
sample result, D is the result of the duplicate, TPUs is the total uncertainty of the original sample and TPUd is the
total uncertainty of the duplicate sample.
Sample Delivery Group Number assigned by the Client or assigned by TestAmerica upon sample receipt.
The sum of the reported alpha spec results for tests derived from the same sample excluding duplicate result where
the results are in the same units.
The LIMS software assign test specific identifier.
The recovery of the tracer added to the sample such as Pu-242 used to trace a Pu-239/40 method.

The analytical result for each analysis performed includes a minimum of one laboratory control sample
(LCS), and one reagent blank sample analysis. Any exceptions have been noted in the "Comments"
section.
V. Comments
Alpha Spectroscopy
Thorium-228, 230, 232
The blank result ofTh-230 has a result above the achieved MDA; suspect some tailing from the Th-229
tracer. The FWHM is elevated, due to the typical and expected tailing from the Th-229 tracer. The
achieved MDA of the samples exceeds the detection limit due insufficient sample volume. There is no
sample volume remaining for re-analysis. Data is reported. Except as noted, the LCS, batch blank and
sample results are within acceptance limits.
Gas Proportional Counting
Pb-210
The achieved MDA of the batch exceeds the detection limit from reduced aliquot sizes taken due to
historical process knowledge. The sample activities exceed the MDAs. Data is accepted. Except as
noted, the LCS, batch blank and sample results are within acceptance limits.
Alpha Scintillation
Radium-226
The achieved MDA of the batch exceeds the detection limit due insufficient sample volume and
limitations of the method in relation to the matrix and available count time. There is no sample volume
remaining for re-analysis. Data is reported. Except as noted, the LCS, batch blank and sample results are
within acceptance limits.
I certify that this Certificate of Analysis is in compliance with the SOW and/or NELAC, both technically

Uncertainty Estimation
TestAmerica Richland has adopted the internationally accepted approach to estimating
uncertainties described in "NIST Technical Note 1297, 1994 Edition". The approach, "Law of Propagation
of Errors", involves the identification of all variables in an analytical method which are used to derive a
result. These variables are related to the analytical result (R) by some functional relationship, R =constants
* f(x,y,z, ... ). The components (x,y,z) are evaluated to determine their contribution to the overall method
uncertainty. The individual component uncertainties (u;) are then combined using a statistical model that
provides the most probable overall uncertainty value. All component uncertainties are categorized as type
A, evaluated by statistical methods, or type B, evaluated by other means. Uncertainties not included in the
components, such as sample homogeneity, are combined with the component uncertainty as the square root
of the sum-of-the-squares ofthe individual uncertainties. The uncertainty associated with the derived result
is the combined uncertainty ( Uc) multiplied by the coverage factor (1 ,2, or 3 ).
When three or more sample replicates are used to derive the analytical result, the type A
uncertainty is the standard deviation of the mean value (S/?n), where Sis the standard deviation of the
derived results. The type B uncertainties are all other random or non-random components that are not
included in the standard deviation.
The derivation of the general "Law ofPropagation ofErrors" equations and specific example are
available on request.

Report Definitions
An t1 •rclld upon tctivit. level used to trigger some action when the final result is greater than or equal to the Action
Level. Often the Action Level is related to the Decision Limit.
The QC preparation batch number that relates laboratory samples to QC samples that were prepared and analyzed
together.
Defined by the equation (Result/Expected)-! as defined by ANSI N 13.30.
Chain of Custody Number assigned by the Client or TestAmerica.
Poisson counting statistics of the gross sample count and background. The uncertainty is absolute and in the same
units as the result. For Liquid Scintillation Counting (LSC) the batch blank count is the background.
All known uncertainties associated with the preparation and analysis of the sample are propagated to give a measure
of the uncertainty associated with the result, Uc the combined uncertainty. The uncertainty is absolute and in the
same units as the result.
The coverage factor defines the width ofthe confidence interval, I, 2 or 3 standard deviations.
Contractual Required Detection Limit as defined in the Client's Statement Of Work or TestAmerica "default"
nominal detection limit. Often referred to the reporting level (RL)
Decision Level based on instrument background or blank, adjusted by the Efficiency, Chemical Yield, and Volume
associated with the sample. The Type I error probability is approximately 5%. Lc=(l.645 *
Sqrt(2*(BkgrndCnt/BkgmdCntMin)/SCntMin)) * (ConvFcti(Eff*Yld*Abn*Vol) * IngrFct). For LSC methods the
batch blank is used as a measure of the background variability. Lc cannot be calculated when the background count
is zero.
The number assigned by the LIMS software to track samples received on the same day for a given client. The
sample number is a sequential number assigned to each sample in the Lot.
Detection Level based on instrument background or blank, adjusted by the Efficiency, Chemical Yield, and Volume
with a Type I and II error probability of approximately 5%. MDC = (4.65 "
Sqrt((BkgmdCnt/BkgmdCntMin)/SCntMin) + 2.71/SCntMin) * (ConvFcti(Eff * Yld * Abn * Vol) * IngrFct). For
LSC methods the batch blank is used as a measure of the background variability.
The instrument identifier associated with the analysis of the sample aliquot.
The U-234 result divided by the U-238 result. The U-234/U-238 ratio for natural uranium in NIST SRM 4321 C is
1.038.
Ratio of the Result to the MDC. A value greater than 1 may indicate activity above background at a high level of
confidence. Caution should be used when applying this factor and it should be used in concert with the qualifiers
associated with the result.
Ratio of the Result to the Total Uncertainty. If the uncertainty has a coverage factor of2 a value greater than I may
indicate activity above background at approximately the 95% level of confidence assuming a two-sided confidence
interval. Caution should be used when applying this factor and it should be used in concert with the qualifiers
associated with the result.
Sample Identifier used by the report system. The number is based upon the first five digits ofthe Work Order
Number.
The equation Replicate Error Ratio= (S-D)/[ sqrt(TPUs2 + TPUd2)] as defined by ICPT BOA where S is the original
sample result, Dis the result of the duplicate, TPUs is the total uncertainty of the original sample and TPUd is the
total uncertainty of the duplicate sample.
Sample Delivery Group Number assigned by the Client or assigned by TestAmerica upon san1ple receipt.
The sum of the reported alpha spec results for tests derived from the same sample excluding duplicate result where
the results are in the same units.
The LIMS software assign test specific identifier.
The recovery of the tracer added to the sample such as Pu-242 used to trace a Pu-239/40 method.
