SUMMARY

OF MONITORING RESULTS 5

Summary The Annual Radiological Environmental Operating Report presents data obtained through analyses of environmental samples collected for Grand Gulf Nuclear Station's (GGNS)

Radiological Environmental Monitoring Program (REMP) for the period January 1, 2013, through December 31, 2013. This report fulfills the requirements of GGNS Technical Specification 5.6.2.

To supplement the REMP, GGNS personnel installed duplicate TLDs and collected duplicate samples during the reporting period.

Radiological Environmental* Monitoring Program GGNS established the REMP in 1978 prior to the station becoming operational (1985) to provide data on background radiation and radioactivity normally present in the area. GGNS has continued to monitor the environment by sampling air, water, sediment, fish and food products, as well as measuring radiation directly. GGNS also samples milk, if commercial milk production occurs within five miles of the plant.

The REMP includes sampling indicator and control locations within an 18-mile radius of the plant. The REMP utilizes indicator locations near the site to show any increases or buildup of radioactivity that might occur due to station operation and control locations farther away from the site to indicate naturally occurring background radioactivity. GGNS personnel compare indicator results with control and preoperational results to assess any impact GGNS operation might have on the surrounding environment.

In 2013, GGNS personnel collected environmental samples for radiological analysis. The monitoring results for indicator locations when compared to control locations and previous studies show that GGNS has no significant effect on the local environment. The review of 2013 monitoring data, in many cases, showed undetectable radiation levels in the environment and near background levels in potential exposure pathways associated with GGNS.

Harmful Effects or Irreversible Damage The REMP monitoring did not detect any harmful effects or evidence of irreversible damage in the current year.

Reporting Levels When averaged over any calendar quarter, no environmental samples equaled or exceeded reporting levels for radioactivity as outlined in Offsite Dose Calculation Manual (ODCM)

Specifications Table 6.12.1-2; the analytical results did not trigger any Radiological Monitoring Program Special Reports.

Radioactivity Not Attributable to GGNS Over previous years, the GGNS REMP detected radioactivity attributable to other sources.

These sources included the Chinese nuclear test in 1980 and the accident at the Chernobyl Nuclear Power Plant in 1986. In 2011, the GGNS REMP detected radioactivity released from the Fukushima Dai-ichi Nuclear Power Plant following the March 11, 2011, Tohoku earthquake.

In 2013, the GGNS REMP detected no radioactivity attributable to other sources.

Comparison to Federal and State Programs GGNS personnel compare REMP data to federal and state monitoring programs. Historically, the programs used for comparison included the U.S. Nuclear Regulatory Commission (NRC)

Thermoluminescent Dosimeter (TLD) Direct Radiation Monitoring Network and the Mississippi State Department of Health (MSDH), Division of Radiological Health monitoring program.

Although the NRC TLD Network Program was discontinued in 1998, these results compared favorably to those from the GGNS REMP.

The MSDH and the GGNS REMP have similar monitoring requirements. These programs include co-located air sampling and sharing sample media such as water, sediment, fish and food products. Both programs have obtained similar results. The 2013 results of the MSDH monitoring program compared favorably with the GGNS REMP results.

Sample Deviations

Milk The GGNS aDCM requires collection of milk samples if there is a commercially available source within 5 miles (8 km) of the plant. In 2013, the REMP did not include milk sampling because no commercial milk production occurred within 5 miles of GGNS.

GGNS personnel instead collected vegetation samples to monitor the ingestion pathway, as specified in aDCM Specifications Table 6.12.1-1.

Required Lower Limit of Detection (LLD) Values Analytical lower limit of detection (LLD) values required by the aDCM specifications were achieved in 2013 were within the limits for all samples with the following exceptions:

Sample Type Location / Analysis Nuclide Date Surface Water Iodine - 131 MS River Downstream / Gamma Ba-140 12/19/2013 La-140 Surface Water Iodine - 131 MS River Upstream / Gamma Ba-140 12/19/2013 La-140 Cause was attributed to excess decay between sample collection and analysis. All remaining LLDs were achieved and no plant related nuclides were detected in the 4013 samples.

MS River samples are collected quarterly at indicator [downstream] and control

[upstream] locations. In addition, an annual sample is collected from an indicator location during a liquid radwaste discharge. For all remaining 2013 MS River samples, LLDs were achieved and no plant related nuclides were detected.

7

Thermoluminescent Dosimeters rd TLDs M-94 and M-99 were retrieved wet in the 3 quarter. Similarly located TLD data were reviewed and found consistent with previous data, with readings near background.

Air Samples The fol.lowing air sample locations had reduced run times due to weather-related power outages or mechanical problems. As described in ODCM Specification Table 6.12.1-1, footnote (a), deviations from the required sampling schedule are permitted due to malfunction of sampling equipment and other legitimate reasons.

1.0 Introduction 1.1 Radiological Environmental Monitoring Program GGNS established the REMP to ensure that plant operating controls properly function to minimize any radiation that could endanger human health or the environment. The REMP is designed to:

Analyze important pathways for anticipated types and quantities of radionuclides released into the environment,

Consider the possibility of a buildup of long-lived radionuclides in the environment and identify any physical and biological accumulations that may contribute to human exposures,

Consider the potential radiation 1

exposure to plant and animal life in the environment surrounding GGNS,

Correlate levels of radiation and radioactivity in the environment with radioactive releases from the operation of GGNS.

1.2 Pathways Monitored The airborne, direct radiation, waterborne and ingestion pathways, as seen in Figure 1-1 are monitored as required by the GGNS ODCM Table 6.12.1-1. A description of the GGNS REMP utilized to monitor the exposure pathways is provided in Table 1.1 and shown in Figures 1-2 and 1-3. GGNS may supplement this program with additional sampling in order to provide a comprehensive and well-balanced program.

Section 2.0 of this report provides a discussion of sampling results, with Section 3.0 providing a summary of results for the monitored exposure pathways.

1.3 land Use Census GGNS personnel conduct a biennial land use census, as required by ODCM Specification 6.12.2. The most recent land use census data are included in Table 2.1. The purpose of this census is to identify land use changes within each of the 16 meteorological sectors and within a 5-mile radius of GGNS that would require modifications to the REMP or the ODCM. The purpose of the census is to identify the nearest:

1) Occupied and unoccupied residences 2 2

2) Garden of greater than 50 square meters (m ) [500 square feet (ft )]

producing broadleaf vegetation

3) Animal milked for human consumption 10

GGNS personnel conduct the land use census by:

Conducting field surveys in each meteorological sector out to five miles in order to confirm:

Nearest occupied residence

Nearest unoccupied residence

Nearest garden and approximate size

Nearest milking animal

Identifying locations on maps and aerial photographs, measuring distances to GGNS and recording results on surveillance data sheets

Comparing current land use census results to previous results from the 2010 census

Contacting the Claiborne County Agent for verification of nearest dairy animals No significant differences were observed between the biennial land use censuses performed in 2010 and 2012.

2.0 Interpretation and Trends of Results 2.1 Air Particulate and Radioiodine Sample Results GGNS did not detect any plant related gamma emitting radionuclides in the quarterly air particulate composites.

The REMP had previously detected airborlle radioactivity attributable to other sources in this pathway. These sources include the Chinese nuclear test in 1980 and the accident at the Chernobyl Nuclear Power Plant in 1986. The GGNS REMP detected radioactivity released from the Fukushima Dai-ichi Nuclear Power Plant following the March 11, 2011, Tohoku earthquake. No radioiodine was detected in 2013.

Table 3.1, which also includes gross beta activity, provides a comparison of the indicator and control means and ranges, further emphasizing that the airborne pathway remains at background levels. In the absence of plant-related gamma radionuclides, gross beta activity is attributed to naturally occurring radionuclides. Similar trends are present for control and indicator locations, which support the presence of naturally occurring radioactivity.

2.2 Thermoluminescent Dosimetry Sample Results GGNS calculates dose by subtracting shield readings from control and indicator location readings and reports measured dose as net exposure, normalized to 92 days. GGNS relies on the comparison of the indicator locations to the control location as an indication of plant impact. Gamma radiation dose in the reporting period is compared to control location readings for previous years as shown in Figure 2-1.

The comparison of the indicator results to the control, and to previous indicator results, as seen in Figure 2-1 and Table 3.1, indicates that plant operation has had no significant impact on ambient radiation levels during the reporting period.

Plant related gamma emitting radionuclides and tritium remained undetectable in the upstream and downstream Mississippi River locations, which is consistent with preoperational and previous operational years. Storm waters contribute to Outfall 007 and can include tritium as a result of washout and entrainment of normal, previously monitored gaseous effluents.

As a result, tritium is occasionally observed. In 2013, when detected, tritium was measured at an average concentration of 1817+/- 444 pCi/L at the Outfall 007 (indicator) location.

In addition to the tritium samples required by the REMP, speCial surface water samples for gamma emitting radionuclides were collected at the Outfall 007 location (Table A 8.1). Plant related gamma emitting radionuclides remained undetectable in this sample.

Based on review of results and historical data, plant operations had no significant impact on this pathway during the reporting period.

24

Groundwater samples were collected from two locations (indicator and control) and analyzed for gamma emitting rad'ionuclides and tritium (Tables A 4.2 and A 4.3). In addition to the samples required by the REMP, an extra sample from the indicator location was analyzed for lodine-131 (Table A 4.3). GGNS did not detect any plant related gamma emitting radionuclides or tritium in groundwater samples during the reporting period.

Based on review of results and historical data, plant operations had no significant impact on this pathway during the reporting period.

2.4 Sediment Sample Results Sediment samples were collected from two locations (indicator and control) and analyzed for gamma emitting radionuclides. In the reporting period, plant related gamma emitting radionuclides were below detectable concentrations in the upstream (control) and downstream (indicator) location.

Based on review of results and historical data, plant operations had no significant impact on this pathway during the reporting period.

2.5 Milk Sample Results Milk samples were not collected within five miles of the site in the reporting period due to the absence of milking animals. Since there are no dairies within five miles of GGNS, and based on non-detectable radioiodine and gamma radionuclides in air and vegetation samples, plant operations had no impact on this pathway during the reporting period.

2.6 Fish Sample Results Fish samples were collected from two locations (indicator and control) and analyzed for gamma emitting radionuclides. GGNS did not detect any plant related gamma emitting radionuclides in fish samples (edible portions) during the reporting period, as has been the case in preoperational and previous operational years. These results indicate that this pathway has not been affected by plant operations.

2.7 Food Product (Vegetation) Sample Results Food product samples were collected from two locations (indicator and control) and analyzed for lodine-131 and gamma emitting radionuclides. GGNS did not detect any plant related lodine-131 or gamma emitting radionuclides in vegetation samples during the reporting period. These results indicate that this pathway has not been affected by plant operations.

2.8 Land Use Census Results Results from the Land Use Census performed in 2012-13 are included in this report.

Methods utilized to perform the Land Use Census include: visual surveys, door to door surveys, telephone interviews, Global Positioning System (GPS), Aerial Photography, and consultation with the local county agent concerning dairy production in Claiborne County.

During the survey the following information was obtained:

1) nearest location of occupied and unoccupied residences

2) nearest location of dairy production

3) nearest location of gardens Changes from the previous Land Use Census were evaluated in accordance with GGNS surveillance "Land Use Census", 06-EN-SOOO-O-0002. The differenceswere compared to the locations and assumptions used in calculations for compliance with the ODCM Limiting Condition for Operation 6.11.6. The locations and assumptions currently used in ODCM were determined more conservative than any of the changes.

Determinations from the most recent Land Use Census results are:

Because of downwind location and/or distance from the site, in no case will the occupancy of an existing LJnoccupied residence cause any existing ODCM critical receptor calculation results to be less conservative.

No additional sampling locations are required as the onsite vegetation sampling location (Sector J, 0.4 miles) is more conservative than changes identified in the land use census.

Cattle are raised for human consumption (most notably in Sector H, J, and K).

GGNS uses the Grass/Cow/Meat pathway.

The milk pathway does not need to be activated because no commercial dairy production is occurring within 5 miles, as referenced by ODCM Table 6.12.1-1.

Sectors M, N, P, and Q are remote areas in which the primary use is hunting.

Areas were surveyed by vehicle and aerial photographs.

2013 ANNUAL QUALITY ASSURANCE REPORT FOR THE RADIOLOGICAL ENVIRONMENTAL MONITO~ING PROGRAM (REMP)

1. Introduction GEL Laboratories, LLC (GEL) is a privately owned environmental laboratory dedicated to providing personalized client services of the highest quality. GEL was established as an analytical testing laboratory in 1981. Now a full service lab, our analytical divisions use state of the art equipment and methods to provide a comprehensive array of organic, inorganic, and radiochemical analyses to meet the needs of our clients.

At GEL, quality is emphasized at every level of personnel throughout the company. Management's ongoing commitment to good professional practice and to the quality of our testing services to our customers is demonstrated by their dedication of personnel and resources to develop, implement, assess, and improve our technical and management operations.

The purpose of GEL's quality assurance program is to establish policies, procedures, and processes to meet or exceed the expectations of our clients. To achieve this, all personnel that support these services to our clients are introduced to the program and policies during their initial orientation, and annually thereafter during company-wide training sessions.

GEL's primary goals are to ensure that all measurement data generated are scientifically and legally defensible, of known and acceptable quality per the data quality objectives (DQOs), and thoroughly documented to provide sound support for environmental decisions. In addition, GEL continues to ensure compliance with all contractual requirements, environmental standards, and regulations established by local, state and federal authorities.

GEL administers the QA program in accordance with the Quality Assurance Plan, GL-QS-B-001. Our Quality Systems include all quality assurance (QA) policies and quality control (QC) procedures necessary to plan, implement, and assess the work we perform. GEL's QA Program establishes a quality management system (QMS) that governs all of the activities of our organization.

This report entails the quality assurance program for the proficiency testing and environmental monitoring aspects of GEL for 2013. GEL's QA Program is designed to monitor the quality of analytical processing associated with environmental, radiobioassay, effluent (10 CFR Part 50), and waste (10 CFR Part 61) sam pie analysis.

This report covers the category of Radiological Environmental Monitoring Program (REMP) and includes:

Intra-laboratory QC results analyzed during 2013.

Inter-laboratory QC results analyzed during 2013 where known values were available.

62

2. Quality Assurance Programs for Inter-laboratory, Intra-laboratory and Third Party Cross-Check In addition to internal and client audits, our laboratory participates in annual performance evaluation studies conducted by independent providers. We routinely participate in the following types of performance audits:

Proficiency testing and other inter-laboratory comparisons

Performance requirements necessary to retain Certifications

Evaluation of recoveries of certified reference and in-house secondary reference materials using statistical process control data.

Evaluation of relative percent difference between measurements through SPC data.

We also participate in a number of proficiency testing programs for federal and state agencies and as required by contracts. It is our policy that no proficiency evaluation samples be analyzed in any special manner. Our annual performance evaluation participation generally includes a combination of studies that support the following:

US Environmental. 'Protection Agency Discharge Monitoring Report, Quality Assurance Program (DMR-QA). Annual national program sponsored by EPA for laboratories engaged in the analysis of samples associated with the NPDES monitoring program. Participation is mandatory for all holders of NPDES permits. The permit holder must analyze for all of the parameters listed 'on the discharge permit. Parameters include general chemistry, metals, BOD/COD, oil and grease, ammonia, nitrates, etc.

Department of Energy Mixed Analyte Performance Evaluation Program (MAPEP). A semiannual program developed by DOE in support of DOE contractors performing waste analyses. Participation is required for all laboratories that perform environmental analytical measurements in support of environmental management activities. This program includes radioactive isotopes in water, soil, vegetation and air filters.

ERA's MRAD-Multimedia Radiochemistry Proficiency test program. This program is for labs seeking certification for radionuclides in wastewater and solid waste. The program is conducted in strict compliance with USEPA National Standards for Water Proficiency study.

ERA's InterLaB RadCheM Proficiency Testing Program for radiological analyses. This program completes the process of replacing the USEPA EMSL-LV Nuclear Radiation Assessment Division program discontinued in 1998. Laboratories seeking certification for radionuclide analysis in drinking water also use the study. This program is conducted in strict compliance with the USEPA National Standards for Water Proficiency Testing Studies. This program encompasses Uranium by EPA method 200.8 (for drinking water certification in Utah/Primary NELAP), gamma emitters, Gross Alpha/Beta, lodine-131, naturally occurring radioactive isotopes, Strontium-89/90, and Tritium.

ERA's Water Pollution (WP) biannual program for waste methodologies includes parameters for both organic and inorganic analytes.

ERA's Water Supply (WS) biannual program for drinking water methodologies includes parameters for organic and inorganic analytes.

o Environmental Cross-Check Program administered by Eckert & Ziegler Analytics, Inc. This program encompasses radionuclides in water, soil, milk, naturally occurring radioactive isotopes in soil and air filters.

63

GEL procures single-blind performance evaluation samples from Eckert & Ziegler Analytics to verify the analysis of sample matrices processed at GEL. Samples are received on a quarterly basis. GEL's Third-Party Cross-Check Program provides environmental matrices encountered in a typical nuclear utility REMP.

The Third-Party Cross-Check Program is intended to meet or exceed the inter-laboratory comparison program requirements discussed in NRC Regulatory Guide 4.15. Once performance evaluation samples have been prepared in accordance with the instructions provided by the PT provider, samples are managed and analyzed in the same manner as environmental samples from GEL's clients.

3. Quality Assurance Program for Internal and External Audits During each annual reporting period, at least one internal assessment of each area of the laboratory is conducted in accordance with the pre-established schedule from Standard Operating Procedure for the Conduct of Quality Audits, GL-QS-E-001. The annual internal audit plan is reviewed for adequacy and includes the scheduled frequency and scope of quality control actions necessary to GEL's QA program.

Internal audits are conducted at least annually in accordance with a schedule approved by the Quality Systems Director. Supplier audits are contingent upon the categorization of the supplier, and mayor may not be conducted prior to the use of a supplier or subcontractor. Type I suppliers and subcontractors, regardless of how they were initially qualified, are re-evaluated at least once every three years.

In addition, prospective customers audit GEL during pre-contract audits. GEL hosts several external audits each year for both our clients and other programs. These programs include environmental monitoring, waste characterization, and radiobioassay. The following list of programs may audit GEL at least annually or up to every three years depending on the program.

The annual radiochemistry laboratory internal audit (13-RAD-001) was conducted in August 2013. Three (3) findings, two (2) observations, and one (1) recommendations resulted from this assessment. By October, 2013, each finding was closed and appropriate laboratory staff addressed each observation and recommendation.

4. Performance Evaluation Acceptance Criteria for Environmental Sample Analysis GEL utilized an acceptance protocol based upon two performance models. For those inter-laboratory programs that already have established performance criteria for bias (i.e., MAPEP, and ERAIELAP), GEL will utilize the criteria for the specific program. For intra-laboratory or third party quality control programs that do not have a specific acceptance criteria (i.e. the Eckert-Ziegler Analytics Environmental Cross-check Program), results will be evaluated in accordance with GEL's internal acceptance criteria.

5. Performance Evaluation Samples Performance Evaluation (PE) results and internal quality control sample results are evaluated in accordance with GEL acceptance criteria. The first criterion concerns bias, which is defined as the deviation of anyone result from the kn'own value. The second criterion concerns precision, which deals with the 64

ability of the measurement to be replicated by comparison of an individual result with the mean of all results for a given sample set.

At GEL, we also evaluate our analytical performance on a regular basis through statistical process control (SPC) acceptance criteria. Where feasible, this criterion is applied to both measures of precision and accuracy and is specific to sample matrix. We establish environmental process control limits at least annually.

For Radiochemistry analysis, quality control evaluation is based on static limits rather than those that are statistically derived. Our current process control limits are maintained in GEL's AlphaLiMS. We also measure precision with matrix duplicates and/or matrix spike duplicates. The upper and lower control limits (UCL and LCL respectively) for precision are plus or minus three times the standard deviation from the mean of a series of relative percent differences. The static precision criteria for radiochemical analyses are o- 20%, for activity levels exceeding the contract required detection limit (CRDL).

6. Quality Control Program for Environmental Sample Analy~is GEL's internal QA Program is designed to include QC functions such as instrumentation calibration checks (to insure proper instrument response), blank samples, instrumentation backgrounds, duplicates, as well as overall staff qualification analyses and statistical process controls. Both quality control. and qualification analyses samples are used to be as similar as the matrix type of those samples submitted for analysis by the various laboratory clients. These performance test samples (or performance evaluation samples) are either actual sample submitted in duplicate in order to evaluate the precision of laboratory measurements, or fortified blank samples, which have been given a known quantity of a radioisotope that is in the interest to GEL's clients.

Accuracy (or Bias) is measured through laboratory control samples and/or matrix spikes, as well as surrogates and internal standards. TheUCLs and LCLs for accuracy are plus or minus three times the standard deviation from the mean of a series of recoveries. The static limit for radiochemical analyses is 75

- 125%. Specific instructions for out-of-control situations are provided in the applicable analytical SOP.

GEL's Laboratory Control Standard (LCS) is an aliquot of reagent water or other blank matrix to which known quantities of the method analytes are added in the laboratory. The LCS is analyzed exactly like a sample, and its purpose is to determine whether the methodology is in control, and whether the laboratory is capable of making accurate and precise measurements. Some methods may refer to these samples as Laboratory Fortified Blanks (LFB). The requirement for recovery is between 75 and 125% for radiological analyses excluding drinking water matrix.

Bias (%) = (observed concentration)

100 %

(known concentration)

Precision is a data quality indicator of the agreement between measurements of the same property, obtained under similar conditions, and how well they conform to themselves. Precision is usually expressed as standard deviation, variance or range in either absolute or relative (percentage) terms.

GEL's laboratory duplicate (DUP or LCSD) is an aliquot of a sample taken from the same container and processed in the same manner under identical laboratory conditions. The aliquot is analyzed independently from the parent sample and the results are compared to measure precision and accuracy.

If a sample duplicate is analyzed, it will be reported as Relative Percent Difference (RPD). The RPD must be 20 percent or less, if both samples are greater than 5 times the MDC. If both results are less than 5 times MDC, then the RPD must be equal to or less than 100% . If one result is above the MDC and the other is below the MDC, then the RPD can be calculated using the MDC for the result of the one below the MDC. The RPD must be 100% or less. In the situation where both results are above the MDC but one 65

result is greater than 5 times the MDC and the other is less than 5 times the MDC, the RPD must be less than or equal to 20%. If both results are below MDC, then the limits on % RPD are not applicable.

Difference (%) = (high duplicate result - low duplicate result)

100 %

(average of results)

7. Summary of Data Results I

During 2013, forty-four (44) radioisotopes associated with seven (7) matrix types were analyzed under GEL's Performance Evaluation program in participation with ERA, MAPEP, and Eckert & Ziegler Analytics.

Matrix types were representative of client analyses performed during 2012. Of the four hundred twenty-three (423) total results reported, 97% (410 of 423) were found to be acceptable. The list below contains the type of matrix evaluated by GEL.

8. Summary of Participation in the Eckert & Ziegler Analytics Environmental Cross-Check Program Eckert & Ziegler Analytics provided samples for eighty-nine (89) individual environmental analyses. The accuracy of each result reported to Eckert & Ziegler ~nalytics, Inc. is measured by the ratio of GEL's result to the known value. All results fell within GEL's acceptance criteria (100%).

9. Summary of Participation in the MAPEP Monitoring Program MAPEP Series 27, 28 and 29 were analyzed by the laboratory. Of the one hundred thirty-eight (138) analyses, 96% (133 out of 138) of all results fell within the PT provider's acceptance criteria. Five analytical failures occurred: Uranium-238/235 and Total Uranium in vegetation by ICP/MS, and Uranium-234/233, and Uranium-238 by Alpha Spectroscopy.

For the corrective actions associated with MAPEP Series 28, refer to CARR130513-789 which is detailed in Table 8.

10. Summary of Participation in the ERA MRaD PT Program The ERA MRad program provided samples (MRAD-18 and MRAD-19) for one hundred fifty (150) individual environmental analyses. One hundred forty-five (145) of the 150 analyses fell within the PT provider's acceptance criteria (97%). Five analytical failures occurred: Cesium-134, Cesium-137 and Zinc-65 in soil, and Uranium-234 and Total Uranium in vegetation.

For the corrective actions associated with MRAD-18 and MRAD-19, refer to CARR 130522-791 and CARR131205-845 which are detailed in Table 8.

11. Summary of Participation in the ERA PT Program The ERA program provided samples (RAD-92 and RAD-94) for forty-six (46) individual environmental analyses. Of the 44 analyses, 93% (43 out of 44) of all results fell within the PT provider's acceptance criteria. Two analytical failures occurred: Gross Alpha and Strontium-89 in water.

For the corrective actions associated with RAD-92 refer to corrective actions CARR130826-81 0 (Table 8).

12. Corrective Action Request and Report (CARR)

There are two categories of corrective action at GEL. One is corrective action implemented at the analytical and data review level in accordance with the analytical SOP. The other is formal corrective action documented by the Quality Systems Team in accordance with GL-QS-E-002. A formal corrective action is initiated when a nonconformance reoccurs or is so significant that permanent elimination or prevention of the problem is required. Formal correctiv,e action investigations include root cause analysis.

GEL includes quality requirements in most analytical standard operating procedures to ensure that data are reported only if the quality control criteria are met or the quality control measures that did not meet the acceptance criteria are documented. A formal corrective action is implemented according to GL-QS-E-002 for Conducting Corrective/Preventive Action and Identifying Opportunities for Improvement. Recording and documentation is performed following guidelines stated in GL-QS-E-012 for Client NCR Database Operation.

Any employee at GEL can identify and report a nonconformance and request that corrective action be

. taken. Any GEL employee can participate on a corrective action team as requested by the QS team or Group Leaders. The steps for conducting corrective action are detailed in GL-QS-E-002. In the event that correctness or validity of the laboratory's test results in doubt, the laboratory will take corrective action. If investigations show that the results have been impacted, affected clients will be informed of the issue in writing within five (5) calendar days of the discovery.

Table 8 provides the status of CARRs for radiological performance testing during 2013. It has been determined that causes of the failures did not impact any data reported to our clients.

If both results are less than 5 times MOC, then the RPO must be equal to or less than 100%. If one result is above the MOC and the other is below the MOC, then the RPO can be calculated using the MOC for the result of the one below the MOC. The RPO must be 100% or less. In the situation where both results are above the MOC but one result is greater than 5 times the MOC and the other is less than 5 times the MOC, the RPO must be less than or equal to 20%. If both results are below MOC, then the limits on % RPO are not applicable.

CORRECTIVE ACTION 10#

& DISPOSITION PE FAilURE CARR130513-789 Root Cause Analysis of MAPEP-13-RdV28 Uranium-234/233, Uranium-235, Uranium-238 and Total ISO Documentation of PT Failures in Uranium MAPEP-13-RdV28 for Uranium in Vegetation by ICP/MS and Alpha Following reviews of our process and data and conversations Spec with personnel from the affected laboratories, it was determined that all failures were due to an analyst error during sample preparation. Glass instead of Teflon beakers were used during the sample digestion which contained Hydrofluoric (HF) acid. Per Standard Operating Procedure (

SOP) Gl-RAD-A-015 section 11.2.4, the sample should have been transferred to a Teflon beaker. In this instance, this step was omitted. The digestion was performed in glass beakers so trace amounts of Uranium were leached from the glass into the sample, resulting in high bias in the results.

Normal procedure dictates that glass is not used when using HF in the digestion process due to the presence of natural Uranium in the glassware.

In order to prove that this was an isolated incident and that our overall process is in control a series of digestions were performed in the glass beakers to confirm our conclusion.

HCl IHN0 3 only digestion - Uranium was not detected.

HCl, HN0 3 , and HF digestion - Enough Uranium activity was detected to account for the high bias (as many as 70 counts in a 16 hour1.851852e-4 days <br />0.00444 hours <br />2.645503e-5 weeks <br />6.088e-6 months <br /> and 40 minute count).

HF only digestion - Results similar to HCl, HN0 3 , and HF were observed A second PT was successfully analyzed for this matrix.

CARR130522-791 Following a review of our processes, the data and conversations with personnel from the affected laboratories, it ISO Documentation of PT Failures in was determined that our normal procedure for preparing soil

-MRAD-18 for Cesium-134, Cesium- samples is not sufficient for this soil matrix. Per the Standard 137 and Zinc-65 in Soil Operating Procedure (SOP) Gl-RAD-A-021 , the sample was dried, homogenized, and passed through a 28 mesh sieve.

However, approximately 20-30% of the sample consists of particles greater than the 28 mesh sieve size. These larger particles were not affected by our normal homogenization 111

CARR130522-791 process. In accordance with the SOP, the larger particles were removed prior to preparing the container for gamma ISO Documentation of PT Failures in counting.

-MRAD-18 for Cesium-134, Cesium-137 and Zinc-65 in Soil Upon receipt of the graded report, the following steps were taken to prove that this was an isolated incident and that our overall process is in control.

1. A recount of the initially prepared sample performed and confirmed the originally reported results.

2. A new container was then prepared from the original sample but omitting the preparation step and counted.

This produced acceptable results.

3. A second sample was prepared per the SOP; however, only a portion of the sample was removed during the sieving steps. This sample produced similar high biased results.

An aliquot of the sample was then pulverized prior to gamma counting. This approach also produced acceptable results.

Permanent Corrective/Preventive Actions or Improvements:

In the future, these samples will be pulverized to ensure that all the material passes through the 28 mesh sieve; thus, eliminating the need to remove any of the original sample. A comment has been added to the set-up for the solid matrix.

A second PT was successfully analyzed for this matrix.

CARR130826-810 For Failures of RAD-94 for Gross Root Cause Analysis of Gross Alpha Alpha/Sea and Strontium 89/90 in After a review of the data, an apparent reason for this Water discrepancy could not be determined. The following steps were taken to prove that this high bias was an isolated occurrence and that our overall process is within cont~ol.

1. The batch quality control samples were reviewed and found to be compliant. The LCS recovered at 110% . While the recovery is slightly elevated, it is well within the 80%-1200/0 acceptance range.

2. Laboratory control data were also reviewed for trends. None were noted.

3. The instrument calibrations were reviewed for positive biases that could have attributed to this failure. None were noted.

4. Two sample duplicates were also prepared and counted along with the reported result. Soth results fell within the method's acceptance range for duplicate. One of the results also fell within the acceptance range of the study.

5. The original sample was also recounted and the results fell within the acceptance range.

Root Cause Analysis of Strontium-89 (Sr-89)

LAB PBMS A-004 After a review of the data, an apparent reason for this discrepancy could not be determined. The following steps were taken to prove that this high bias was an isolated occurrence and that our overall process is within control.

1. The batch quality control samples were reviewed and found to be compliant. The LCS recovered at 98.1 %.

2. Laboratory control data were also reviewed for trends. None were noted.

3. The instrument calibrations were reviewed for positive biases that could have attributed to this failure. None were noted.

4. Sample duplicates were also prepared and counted along with the reported result. Duplicate results fell within the acceptance range of the study.

Root Cause Analysis of Strontium-89 (Sr-89)

EPA 905.0 After a review of the data, an .apparent reason for this discrepancy could not be determined. The following steps were taken to prove that this high bias was an isolated occurrence and that our overall process is within control.

1. The batch quality control samples were reviewed and found to be compliant. The LCS recovered at 102%.

113

CARR130826-810 2. Laboratory control data were also reviewed for trends. None was noted.

For Failures of RAD-94 for Gross 3. The instrument calibrations were reviewed for Alpha/Sea and Strontium 89/90 in positive biases that could have attributed to this Water failure. None were noted.

4. Sample duplicates were also prepared and counted along with the reported result. All results fell 'within the method's acceptance range for duplicates.

Permanent Corrective/Preventive Actions or Improvements:

Gross Alpha The laboratory must assume an unidentified random error caused the high bias because all quality control criteria were met for the batch. The lab will continue to monitor the recoveries of this radionuclide to ensure that there are no issues.

Strontium-89 (Sr-89)

LAB PBMS A-004 and EPA 905.0 To summarize our efforts (including the initial result), the laboratory had 3 analysts, two different methods, processed with 2 calibrations and two separate Y carriers used in the analysis of this sample and only one acceptable result for Sr-'

89. All LCS results have met acceptance criteria. This leads the laboratory to conclude that there is possibly an error in the original make-up of the PT sample. The instructions list stable Sr andY as being included but they are not at levels greater than are normally listed so we suspect that the make up of the sample was the cause. The laboratory will continue to monitor the recoveries from these two methods to ensure that there are no issues.

Root Cause Analysis CARR131205-845 These elevated results were obtained following our routine For failures of MRAD-19 for Uranium- procedure. The reported result for U-234 was less than the 234 and Total Uranium in Vegetation MDA and had a elevated uncertainty. This high U-234 result also attributed to the high Total-U result.

Upon receipt of the graded report, the following steps were taken to prove that this was an isolated incident and that our overall process is in control.

A recount of the initially prepared sample performed and confirmed the originally reported results.

. The sample was reanalyzed using a larger aliquot and results that fell within the acceptance range were achieved.

Permanent Corrective/Preventive Actions or Improvements In the future when the result is below the MDA and are not compatible with other analytical technologies, the laboratory will attempt to use a larger sample aliquot with hopes of achieve a result above the MDA or with a lower uncertainty. If the matrix and larger sample size do not provide useable data, the results may not be reported.
