Introduction Results of the Radiological Environmental Monitoring Program for the Comanche Peak Nuclear Power Plant (CPNPP) are contained within this report. This rep01i covers the period from January 1, 2018 through December 31, 2018 and summarizes the results of measurements and analysis of data obtained from environmental samples collected during this same timeframe.

A. Site and Station Description CPNPP consists of two pressurized water reactor units, each designed to operate at a power level of about 1250 megawatts (electrical). The Station is located on Squaw Creek reservoir in Somervell and Hood counties, about forty miles southwest of Fort Worth, Texas. Unit 1 received a low power operating license February 8, 1990 and achieved initial criticality on April 3, 1990. A full power license for Unit I was issued on April 17, 1990 and commercial operation was declared on August 13, 1990. Unit 2 achieved initial criticality on March 24, 1993 and synchronized to the electrical grid on April 9, 1993.

B. Objectives and Overviews of the CPNPP Radiological Environmental Monitoring Program The United States Nuclear Regulatory Commission (USNRC) regulations require that nuclear power plants be designed, constructed, and operated to keep levels ofradioactive material in effluents to unrestricted areas as low as reasonably achievable (ALARA). To assure that these criteria are met, each license authorizing reactor operation includes technical specifications governing the release of radioactive effluents.

In-plant monitoring is used to assure that these predetennined release limits are not exceeded. However, as a precaution against unexpected and undefined processes that might allow undue accmnulation ofradioactivity in any sector of the environment, a program for monitoring the plant environs is also included.

Sampling locations were selected on the basis of local ecology, meteorology, physical characteristics of the region, and demographic and land use features of the site vicinity. The radiological enviromnental monitoring program was designed on the basis of the USNRC Branch Technical Position "An Acceptable Radiological Environmental Monitoring Program" on radiological environmental monitoring issued by the Radiological Assessment Branch, Revision 1 (November 1979), the CPNPP Technical Specification "Technical Specifications for Comanche Peak Nuclear Power Plant Units 1 and 2" and the "CPSES Offsite Dose Calculation Manual" (ODCM).

The Radiological Environmental Monitoring Program includes the following:

The measurement of ambient gamma radiation by Thermal Luminescent dosimetry;

The determination of airborne gross beta, gamma emitters, and Iodine-131;

The determination of tritium and gamma emitters in Discharge Pathway surface water;

The determination of gross beta, tritium, Iodine-131, and gamma emitters in potential drinking water sources;

The detennination of tritium and gamma emitters in ground water and fish; e The determination of gamma emitters in sediment;

The determination of gamma emitters in food products and;

The determination of gamma emitters and Iodine-131 in broadleaf vegetation.

The regulations governing the quantities of radioactivity in reactor effluents allow nuclear power plants to contribute, at most, only a small percentage increase above normal background radioactivity. Background levels at any one location are not constant but vary with time as they are influenced by external events such as cosmic ray bombardment; weapons test fallout, and seasonal variations. These levels also can vary spatially within relatively short distances reflecting variations in geological composition. To differentiate between background radiation levels and increases resulting from operation of CPNPP, the radiological surveys of the plant environs were divided into pre-operational and operational phases.

The pre-operational phase of the program provided a general characterization of the radiation levels and concentrations prevalent in these areas prior to plant operation along with an indication of the degree of natural variation to be expected. The operational phase of the program obtains data which, when considered along with the data obtained in the pre-operational phase, assists in the evaluation of the radiological impact of plant operation.

6

Pre-operational measurements were conducted at CPNPP from 1981 to 1989. These pre-operational measurements were perfonned to:

Evaluate procedures, equipment, and techniques;

Identify potentially important pathways to be monitored after plant operation;

Measure background levels and the variations along potentially impo1tant pathways; e Provide baseline data for statistical comparisons with future operational analytical results.

The operational Radiological Environmental Monitoring Program is conducted to:

Verify that measurable concentrations of radioactive materials and levels of radiation are not higher than expected on the basis of the effluent measurements and modeling of the enviromnental exposure pathways; e Verify the effectiveness of in-plant measures used for controlling the release of radioactive materials;

Identify changes in the areas at and beyond the site boundary that may impact the principal pathways of exposure.

This report documents the twenty-ninth year of operational measurements and is submitted in accordance with the requirements of the CPSES Offsite Dose Calculation Manual, Part I, Administrative Control 6.9.1.3.

Note: Comanche Peak Steam Electric Station (CPSES) is equivalent to Comanche Peak Nuclear Power Plant (CPNPP).

Program Descriptions and Results A. Sample Locations Within a radius of twenty miles of the CPNPP site there are seventy-two (72) sample locations included in the monitoring program. The number of sample points and the specific locations for the sample points were detennined by considering locations where the highest off-site environmental concentrations have been predicted from plant effluent source terms, site hydrology, and site meteorological conditions. Other factors considered were applicable regulations, population distribution, and ease of access to sampling stations, availability of samples at desired locations, security and future program integrity. Additionally, an annual land use census is conducted to identify changes in the areas sunounding the plant. If changes are identified that impact the principle pathways of exposure, appropriate changes to the radiological environmental monitoring program are implemented. A copy of the report "Comanche 7

Peak Nuclear Power Plant Land Use Census" is provided in Appendix A to this report.

Table 1 - Comanche Peak Nuclear Power Plant Radiological Environmental Monitoring Program contains a brief outline of the current program. This table specifies the sample media type, the number of locations for each media type, the sector and distance identifier for each sample location, the sample frequency, the type of analysis required and the frequency each analysis is required to be performed (Analytical Frequency).

Table 2 - Key to Environmental Sampling Locations provides a reference that links the sampling point designations used in procedures and forms to the appropriate physical sample location (sector and distance) and to the correct sample type. This cross-reference enhances the ability to review data and tie the data to the correct sample points and to ensure all samples are collected and analyzed as specified.

Currently there are no milk sample locations within ten miles of the CPNPP site. CPNPP already samples extra broadleaf locations as required due to no milk locations within the ten-mile radius therefore, no changes to the program are necessary. Mille sampling will be resumed if any future annual land use census determines a dairy has been established within the specified area.

B. Direct Radiation Starting in 2013 Thermo Luminescent Dosimeters (TLDs) were used to determine the direct (ambient) radiation levels at the designated monitoring locations. The monitoring locations were chosen according to the criteria given in the USNRC Branch Teclmical Position on Radiation Monitoring (Revision 1, November 1979). The area around the station was divided into 16 radial sectors of 22-1 /2 degrees each, corresponding to the cardinal points of the compass. TLDs were placed in each of these sectors. The TLDs were placed in two rings around the station. An inner ring was located as close as possible to the site boundary and an outer ring was located at a distance of 4 to 6 miles from the station. Eleven additional TLDs were located at points of special interest, including two control locations. For routine direct radiation measurements, two sets of the TLDs were used at each of the 43 monitoring locations. One set of TLDs was exchanged on a quarterly basis and a second set of TLDs was exchanged on a yearly basis. Additional sets of in-transit TLDs were used as control TLDs for the quarterly and annual TLDs.

Mirion Technologies provides and processes Thermo Luminescent Dosimeters (TLDs.) The TLDs are used to determine the direct (ambient) radiation levels in designated monitoring locations. Mirion Technologies is accredited by the National Voluntary Laboratory Accreditation Program (NVLAP.) .

D. C. Oakley's report National Radiation Exposure in the United States",

published in 1972, calculated a background radiation dose rate equivalent of 0.22 mR/day for the area surrounding Fort Worth, Texas. This calculated value varies widely with changes in location but represents an appropriate reference value to compare with actual measured TLD doses.

Using data from the pre-operational program for the two years prior to the startup of Unit 1, the quarterlyTLDs averaged a calculated dose rate of 0.14 mR/day while the yearly TLDs averaged a calculated dose rate of 0.16 mR/day. The range of measured values from this same two-year period varied from a minimum of0.11 mR/dayto a maximum of0.22 mR/day.

Table 3 - Environmental Direct Radiation Results contains the measured dose (mR) for each quarterly TLD from each of the 43 monitoring locations. The corresponding quarterly calculated dose rate (mR/day) values are listed as well. The statistical average doses (mR) and dose rate (mR/day) values for each set of quarterly TLDs is also displayed.

Additionally, the table includes the total dose (mR) of all four quarters for each specific location. The table also includes the measured dose (mR) for each annual TLD from each of the 43 monitoring locations. The corresponding annual calculated dose rate (mR/day) values are listed as well. The statistical annual average dose (mR) for the entire set of annual TLDs is reported along with the average dose rate (mR/day) for the entire set of annual TLDs.

11

The measured dose rates of all the quarterly TLDs ranged from a minimum of 0.095 mR/day to a maximum of 0.206 mR/day with an average dose rate of0.136 mR/day. This resulted in an average quarterly dose of 13 mR and a total annual dose of 46 mR for all of the forty-three monitoring stations.

The measured dose rates of all the annual TLDs ranged from a minimum of 0.085 mR/day to a maximum of 0.167 mR/day with an average dose rate of 0.125 mR/day. This resulted in an average annual dose of 12 mR and a total annual dose average of 45.7 mR for all of the forty-three monitoring stations.

Comparing the pre-operational data and operational data collected through the year 2018 did not produce any anomalies. The direct radiation dose data was consistent with previous years of data during the pre-operational program. Annual Environmental TLDs were compared against the baseline data established in EV-TR.-2015-007304-6 and no anomalies were identified.

Table 6-TLD Trend Quarterly Average contains the average quarterly TLD data for the five most current years and the Annual totals for 2018 from each of the 43 monitoring locations. The implementation of the Mirion TLDs and the background subtract method used to report the data from the TLDs accounts for the lower values and accounts for consistent response from each location's total quarterlyTLDs to the Annual TLDs.

See CR-2013-004934 for additional clarification on the background subtraction method.

During the year 2018, there was two exceptions to the TLD Program.

CRs are represented by

on Table 3.

CR-2018-006468: During the quarterly environmental TLD change out, it was discovered that Rl 8 annual and quarterly badges were missing.

CR-2019-002077: Location R25 for 2018 4th quarter received unusual elements observed, no dose assigned (defective/damaged DLR).

C. Airborne Program Air particulate and air iodine samples were collected each week from the eight monitoring locations described in Table 1 - Comanche Peak Nuclear Power Plant Environmental Radiological Monitoring Program (as seen in section II.A). Each air particulate sample was collected by drawing air through a 47 millimeter-diameter glass-fiber filter. Air iodine was collected by drawing air through an impregnated charcoal cartridge which was connected in series behind the air particulate filter. Shipped to an independent laboratory, air particulate filters were analyzed weekly for gross beta activity and were composited quarterly for gamma spectrometry analysis. Charcoal cartridges were analyzed weekly for Iodine-131.

A total of 416 air particulate filters were collected and analyzed for gross beta activity. The reported gross beta activity ranged :from a minimum value ofl.91E-02 pCi/m3 to a maximum value of7.84E-02 pCi/m3 (control group excluded). Table 4- Environmental Airborne Particulate Gross Beta Results contains the reported values of all samples. There were no anomalies noted in the data reported for 2018 when compared to pre-operational and previous operational data. Graph 1 - Environmental Air Sample Gross Beta Results - Maximum and Minimum trends the weekly high and low gross beta values to show the seasonal variation of the results as well as providing indication of consistency between the individual monitoring locations.

A total of 416 charcoal cartridges were analyzed for airborne Iodine-131.

Table 5-Environmental Air Sample Iodine-131 Results contains the reported values of each Iodine-131 analysis, all of which are less than reportable levels.

All air particulate filters were collected and composited quarterly and then analyzed by gamma spectrometry. Typical of pre-operational and previous operational data results, the only radioactive nuclide identified in all the samples was cosmogenic Beryllilun-7, a naturally occurring isotope.

During the year 2018, there were five exceptions to the Airborne Program.

CR-2018"000250: Due to losing power on the 25KV loop on Saturday the 6th of January, the environmental air samples stations did not receive the full run time of 168 hours0.00194 days 0.0467 hours 2.777778e-4 weeks 6.3924e-5 months . The stations A-7 (SW/WSW"0.95) and A-5 (S/SSW-1.2).

CR-2018-001611: While performing the weekly environmental nm, it was discovered that Air Sample Location A-5 (S/SSW-1.2) only ran for 4 hours4.62963e-5 days 0.00111 hours 6.613757e-6 weeks 1.522e-6 months and 12 min. Further investigation shows a dead battery on the telemetry unit.

This power outage was due to the 25K loop being out of service.

CR-2018-003671; While performing the weekly air sample collection, location A-3, (Happy Hills Fann), The air sampler run for a total time of 36 hrs and 21 mins. The reason for the short run time was due to transformer work. The unit's power has been restored .

.CR-2019-000790; Gel Labs reported a "M" flag for location A-2 from the gross beta result. Lab re-analyzed and verified the result to be satisfactory.

D. Discharge Pathway Surface Water Program Discharge Pathway Surface water monitoring stations are found at four locations as detailed in Table 1 - Comanche Peak Nuclear Power Plant Radiological Envirorunental Monitoring Program. Location N-1.5 provides samples representative of Squaw Creek reservoir surface water at a location beyond significant influence of the plant discharge. Location ESE-1.4 provides samples representative of discharges from Squaw Creek reservoir downstream to Squaw Creek and to Lake Granbury via an installed return line. [NOTE: The installed return line to Lake Granbury has never been used to send water back to Lake Granbu1y.] Location NE-7.4 provides samples of Lake Granbury surface water downstream of the discharge from the return line from Squaw Creek reservoir. A control sample is obtained from the Brazos River, upstream of Lake Granbury at location N~l9.3. Discharge Pathway Surface water samples from Squaw Creek reservoir locations were collected weekly and composited for monthly gamma isotopic analysis. Samples from Lake Granbury locations were collected monthly and analyzed by gamma spectrometry. All Discharge Pathway Surface Water samples were also composited quarterly by location for tritium analysis.

All Discharge Pathways Surface Water samples were collected as required. Forty-eight samples were analyzed by gamma spectrometry. All results for the required radionuclides were reported as less than the required LLDs. Sixteen quarterly composited samples were analyzed for tritium. The results of the reported tritium values for Squaw Creek reservoir were in line with expected concentrations: The tritium values ranged from a high of 1.35E+04 pCi/1 to a low of 1.15E+04 pCi/1. The results from Lake Granbury were all less than the required LLDs as expected. The tritium concentration reported in Squaw Creek is well below the action level of 3.0E+4 pCi/1 and is following the expected concentration variations based on fuel cycles, power histories and reservoir makeup due to rain and pump transfers from Lake Granbury.

Graph 3 - Enviromnental Surface Water Tritium Results indicates the current results and the short-term trend of the tritium concentration in Squaw Creek reservoir, Squaw Creek spillway, Lake Granbury, and Brazos River (control location). Graph 4 - Squaw Creek Maximum Tritium Values trends the reservoir tritimn concentration since it was first detected in 1990 after Unit 1 startup. Squaw Creek reservoir tritium is a direct product from the operation of CPNPP.

20

There should not be any significant changes in the tritium concentrations in the near future and no action levels are anticipated . A review of pre-operational and operational data indicated the 2018 results were both expected and consistent with previous data and that no anomalies had occurred.

During the year 2018, there were no exceptions to the Discharge Pathway Surface Water.

E. Squaw Creek and Lake Granbury Surface Water Program Surface water was collected at two monitoring locations. Table 1 --

Comanche Peak Nuclear Power Plant Radiological Environmental Monitoring Program details the location and types of analysis required.

Samples of water from Squaw Creek reservoir were collected at the monitoring location NNW-0.1. There is not a surface water drinking source within a mile of CPNPP. Monitoring location N-9 .9 is used as a surface drinking water location based on the proximity of the City of Granbury intake to the Granbury potable water system. All surface water samples were collected weekly and then composited for Iodine-131 analysis, gamma isotopic analysis, and gross beta analysis on a monthly basis. Tritium analysis was performed on a quarterly basis.

All samples were analyzed for gamma emitting radionuclides. There were no gamma emitting radionuclides identified in any of the twenty-four composite samples. Tritium rep01ied in Squaw Creek reservoir ranged from 1.12E+04 pCi/l to 1.61E+04 pCi/1 and avei-aged 1.37E+04 pCi/1.

Tritium reported from all Lake Granbury water samples indicated less than the required LLD as expected. Graph 5 - Environmental Squaw Creek and Lake Granbmy Surface Water Tritium Results trends the results reported for the year 2018. Gross Beta results at the indicator location NNW-0.1 ranged from 7 .97+00 pCi/1 to 2.37E+Ol pCi/1 with an average of 15.8E+Ol pCi/l. Gross Beta results at the control location N-9.9 ranged from 4.90E+OO pCi/l to 8.99E+OO pCi/1 with an average of 6.95E+OO pCi/1. Graph 6 - Environmental Squaw Creek and Lake Granbury Surface Water Gross Beta Results trends the gross beta results for the two monitor locations and indicates no influence from Comanche Peak in the levels detected in the two different bodies of water. Past gross beta results for Lake Granbury have been as high as 8.99E+Ol pCi/1, which is still with in acceptable levels for gross beta. The gross beta results received are within values previously reported and there is no reportable level for gross beta so no action is required at this time.

During the year 2018, there were no exception to the Surface Water Program.

F. Ground Water Program Table 1 - Comanche Peak Nuclear Power Plant Radiological Environmental Monitoring Program specifies the five groundwater monitoring locations. Groundwater supplies in the site area are not affected by plant effluents and are sampled only to provide confirmation that groundwater is not affected by plant discharges. Groundwater samples were collected quarterly and analyzed for gamma isotopes and tritium at each location.

A total of twenty groundwater samples were collected from the five different monitoring locations. There were no radionuclides identified in any of the samples. All required LLDs were met for each required gamma emitting radionuclide. Tritium analysis was performed on twenty samples, all indicated less than the required LLD. The results confirm that plant discharges are having no effect on groundwater in the area surrounding Comanche Peak.

Groundwater samples are taken quarterly in accordance with STA-654, "Groundwater Protection Program".

During the year 2018, there were no exceptions to the Ground Water Program.

24

G. Sediment Program Table 1 - Comanche Peak Nuclear Power Plant Radiological Environmental Monitoring Program specifies shoreline sediments were collected at four different monitoring locations. One sample location is along the shore of Squaw Creek Reservoir, one sample location is on Squaw Creek downstream of the dam discharge and two locations are along Lake Granbury's shores. Each sample is collected on a six-month frequency and sent to the contract laboratory for analysis by gamma spectrometry.

The process of shoreline sedimentation is a complex evolution whereby potential radionuclides and stable elements may concentrate in the bottom sediment of particular bodies of water. The concentrations are effected by such things as colloidal particles combining with chelating agents and biological action of bacteria and other benthic organisms. Monitoring of the area shorelines provides one of the first and best indicators of radionuclide deposition.

As expected and in agreement with previous results from both the pre-operational and operational programs, naturally occurring Potassium-40 was detected in all eight samples and Beryillum-7 was detected in one samples. All required radionuclide results were reported as less than the required LLDs. During previous years, both pre-operational and operational, positive indications occasionally had been noted for Cesium-137 however during 2018 there were no positive Cesium-137 results reported. As expected, there were no results in any sediment sample that indicated any direct influence from CPNPP discharges to the local environment.

During the year 2018, there were no exceptions to the Sediment Program 25

H. Fish Program Fish samples were collected at two locations. One monitoring location is an area approximately two miles east-northeast of the site on Squaw Creek Reservoir. The second location is on Lake Granbury approximately eight miles north-northeast of the site. Fish sampling is scheduled for the months of April and November. The collected fish are frozen and shipped to the independent laboratory where the edible portions are analyzed for gamma emitting radio-nuclides. Annually, tritium analysis is performed on Squaw Creek fish (CR-2014-013335).

Catfish and Bass samples were analyzed. There were no positive results reported except for the expected Potassium-40, which is naturally occurring in all living organisms. All required radionuclide results were reported as less than the required LLDs. As a result*of the fish-sampling program, there were no anomalies noted and no indication of any influence on the surrounding enviromnent from Comanche Peak plant discharges.

No abnonnal results were reported by CPNPP or by the State of Texas. As expected, Potassium-40 was the only positive isotope found.

During the year 2018 there were no exceptions to the Fish Program.

26

I. Food Products Program Food products (pecans) were collected at the time of harvest. The samples are obtained at monitoring location ENE-9.0 at the time of harvest and are shipped to the contract laboratory for grumna isotopic analysis. There ,

were food products ( cucumbers, tomatoes, squash) produced that required monitoring for location E-4.2 in 2018.

Naturally occurring Potassium 40 was detected in the samples as expected and all other required radionuclide results were reported as less than the required LLDs.

During the year 2018, there were no exceptions to the Food Products Program.

27

J. Broadleaf Program Broadleaf sample collection is conducted in accordance with the requirements of the Radiological Environmental Monitoring Program.

The program specifies the sampling based on the absence of milk monitoring locations. One broadleaf control location is located at SW" 13 .5 in the vicinity of the previous control milk location. The two indicator locations, N" 1.45 and SW" 1. 0, are located near the site boundaries. The broadleaf samples consist of mainly native grasses and are analyzed for Iodine" 131 and gamma emitting isotopes.

All radionuclide analysis met their required LLDs. The naturally occurring radionuclides of Potassium"40 was found in 36 of 36 samples taken and radionuclide Beryllium"7 was present in 35 of 36 samples.

Dm-ing the year 2018, there were no exception to the Broadleaf Program.

28

K. Conclusions Based on the results presented in this report and from comparisons with the pre-operational and operational program results from previous years, it can be concluded that the impact of Comanche Peak on the environment is minimal.

The only indication directly attributable to Comanche Peak is the tritium detected in Squaw Creek reservoir.

The tritium in Squaw Creek reservoir is reaching equilibrium and is expected to remain well below the reportable level.

Gross beta trend indications concerning Squaw Creek Reservoir are consistent with previous values and do not indicate any increase due to influence from Comanche Peak. Future data will be evaluated as it is received and will be addressed as necessary.

There were no values reported during the year 2018 that exceeded any NRC reportable limit.

2018 ANNUAL QUALITY ASSURANCE REPORT FOR THE RADIOLOGICAL ENVIRONMENTAL MONITORING 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 2018. 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) sample analysis.

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

Intra-laboratory QC results analyzed during 2018.

Inter-laboratory QC results analyzed during 2018 where known values are available.

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:

GEL Laborntorles LLG PO Box aon2 Charlostoo, SC 29417 2040 Savaao Road Charloston, SC29407 P 843.556.6171 FB43.766.1178 www,oal,oom Page 5 of51

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.

Participafion is mandatory for arr holders of NPDES permits. The permit holder must analyze for arr of the parameters listed on the discharge permil 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 ail 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 lnterLaB 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, iodine-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.

Environmental Cross-Check Program administered by Eckert & Ziegler Analytics, inc.

This p~ogram encompasses radionuclides in water, soil, milk, naturally occurring radioactive isotopes in soil and air filters.

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 GEL Laboratories LLC PO Box30712 Cherlenton, SG20417 2040 Savage 11oad Charleston, sc 29407 ~ B43.55B.B171 f B43,7BB.117B www.gal.com Page 6 of 51

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 may or 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.

TNI, The NELAC Institute, National Environmental Laboratory Accreditation Program

DOECAP, U.S. Department of Energy Consolidated Audit Program

DOELAP, U.S. Department of Energy Laboratory Accreditation Program

DOE QSAS, U.S. Department of Energy, Quality Systems for Analytical Seivices

ISO/IEC 17025:2005

A2LA, American Association for Laboratory Accreditation

DoD ELAP, US Department of Defense Environmental Accreditation Program

NUPIC, Nuclear Procurement Issues Committee

South Carolina Department of Health and Environmental Control (SC DHEC)

The annual radiochemistry laboratory internal audit (18-RAD-001) was conducted in May, 2018. One (1) observation, and five (5) recommendation resulted from this assessment.

By June, 2018, the appropriate laboratory staff addressed the observation and recommendations.

4. Performance Evaluation Acceptance Criteria for Environmental Sample Analysis GEL utillzed 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 ERA/ELAP), 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 any one result from the known value. The second criterion concerns precision, which deals with the ability of the measurement to be GEL Laboratories LLC PO BDx 30712 Cha~eslon, SG 20417 2040 Savage Road Cl1arlos1on, sc 29407 P 943.558.8171 F1143.766.1170 www.uet.com Page 7 of51

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 Analysis 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. The UCLs 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 most 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%.

GEL Laboratories LLG PO Box30712 Charleston, SC 29417 2040 Sava.go Road Charleston, sc 29407 PB43.556.8171 F843,766,1176 www.gal.com Page 8 of 51

If one result is above the MDC and the other is below the MDC, then the RPO can be calculated using the MDC for the result of the one below the MDC. The RPO must be 100%

or less. In the situation where both results are above the MDC but one result is greater than 5 times the MDC and the other is less than 5 times the MDC, the RPO 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 During 2018, forty-five (45) 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 2018. Of the four hundred fifty-two (452) total results, 98.4% (445 of 452) were found to be acceptable within the PT providers three sigma or other statistical criteria. 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 ninety-two (92) individual environmental analyses. The accuracy of each result reported to Eckert & Ziegler Analytics, Inc. is measured by the ratio of GEL's result to the known value. All results fell within GEL's acceptance criteria (100% within acceptance).

9. Summary of Participation in the MAPEP Monitoring Program MAPEP Series 38 and 39 were analyzed by the laboratory. All one hundred twenty-four (124) analyses fell within the PT provider's acceptance criteria (100% within acceptance).

10. Summary of Participation in the ERA MRaD PT Program The ERA MRad program provided samples (MRAD~28 and MRAD-29) for one hundred eighty-seven (187) Individual environmental analyses. Of the 187 analyses, 97.3% (182 out of 187) of all results fell within the PT provider's acceptance criteria.

11. Summary of Participation in the ERA PT Program The ERA program provided samples (RAD-112 and RAD-114) for forty-nine (49) individual environmental analyses. Of the 49 analyses, 95.9% (47 out of 49) of all results fell within the PT provider's acceptance criteria.

CARR180226-1150 documents the unacceptable result of Natural Uranium (and mass) via KPA of ERA Study 112, CARR180522-1154 documents the unacceptable results of Uranium-234, Uranium-238, Uranium-Mass and Cobalt-60 in vegetation of ERA MRAD-28, and CARR 181120-1190 documents the unacceptable result of lron-55 in water of ERA MRAD-29. All corrective actions are summarized in 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 analytrcal 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 corrective 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 nonconforrnance 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 2018. It has been determined that causes of the failures did not impact any data reported to our clients.

Both reported values fell slightly above the acceptance criteria of the study.

Permanent Corrective/Preventive Actions or Improvements The laboratory must assume unidentified random errors caused the biases because all quality control criteria were met for the batches. The sample was re-analyzed after the "Not Acceptable" rating was received and a result that fell within the acceptance range was obtained. CARR180522-1154 Root Cause Analysis ISO Documentation of PT Failures in Cobalt MRAD-28 for Uranium-234, Uranium-238, Uranium-Total (mass), and Cobalt-60 in The data was reviewed and no anomalies noted. The Duplicate Vegetation result of the original analysis met the acceptance criteria of the study. The laboratory analyzed a separate aliquot of the sample and while the Co-60 was within limits, the results in general demonstrated a high bias. Uranium The data was reviewed and no anomalies noted. A reanalysis was performed and results were within acceptance limits. A homogenization issue is suspected due to additional high bias in other alpha spec parameters. Permanent Corrective/Preventive Actions or Improvements : The laboratory will continue to monitor the recoveries of these parameters in both methods for vegetation to ensure that there are I no continued issues as well as evaluating the homogenization process. The sample was reanalyzed according to the same procedures as the original results and reanalysis results for the isotopes were within acceptance limits.

CARR181120-1190 Root Cause Analysis ISO Documentation of PT Failure in MRAD lron-55 29 for Fe-55 in water. The data was reviewed and no errors were noted. The laboratory analyzed a separate aliquot of the sample which met replication criteria with in the analysis batch. All other QC met criteria. Due to the high bias being nearly twice the reference value, it is suspected that the laboratory recoded an incorrect aliquot during the analysis process. The typical aliquot for this PT analysis is 20 ml and an aliquot of 10 ml was recorded as the aliquot used. A reanalysis was performed and results were within acceptance limits The laboratory will continue to monitor the recoveries of this parameters to ensure that there are no continued issues in the process. Permanent Corrective/Preventive Actions or Improvements None needed at this time. The laboratory must assume unidentified random errors caused the biases because all quality control criteria were met for the batches.

This data does not replace the Certificates of Analysis provided by GEL. Certificates of Analysis undergo an additional level of review before being sent to the client that Notes:

1. LLDs are a-priori values.

2. MDCs are calculated a-posteriori values.

3. Gamma spectroscopy analysis results are calculated from a measurement using only one gamma em

4. Air sample volumes are received in units of ft3. GEL converts the units and reports them as m3.

QUALIFIERS: U Target isotope was analyzed for but not detected above the MDC or LLD. UI Uncertain identification for gamma spectroscopy.

Notes:

1. LLDs are a-priori values.

2. MDCs are calculated a-posteriori values.

3. Gamma spectroscopy analysis results are calculated from a measurement using only one gamma en,

The data obtained from this website 1s the most accurate possible at the time of your query and based upon your specific inquiry. This data does not replace the Certificates of Analysis provided by GEL. Certificates of Analysis undergo an additional level of review before being sent to the Notes:

1. LLDs are a-priori values.

2. MDCs are calculated a-posteriori values.

3. Gamma spectroscopy analysis results are calculated from a measurement using only one gamma 1

4. Air sample volumes are received in units of ft3. GEL converts the units and reports them as m3.

QUALIFIERS: U Target isotope was analyzed for but not detected above the MDC or LLD. UI Uncertain identification for gamma spectroscopy. X Lab-specific qualifier-please see case narrative, data summary package or contact your project ma M Reported result is less than the LLD and greater than the MDC. DL DL MDC> LLD.

Evaluation of the 2018 Land Use Census The results of the 2018 Land Use Census were reviewed for impact on the Radiological Enviromnental Monitoring Program (REMP). The specific areas reviewed, that could be affected by changes found in the land use census, were the sampling requirements for milk, broadleaf vegetation and food products. Reviewing the milk sampling requirements from the ODCM Table 3.12-1 requires that samples are to be obtained from milking animals in three locations within a 5 km distance having the highest potential dose. If none are available, samples are acceptable from milking animals in locations 5 to 8 km distance where doses are calculated to be greater than 1 mRem per year. A sample is also required at a control location. There are currently no identified milking animals (cow or goat) within the specified distances therefore; there are no current milk samples during the year 2018. If no milk samples are available, the broadleaf vegetation sampling specified in ODCM Table 3.12-1 will be performed. Broadleaf sample requirements are such that samples of broadleaf vegetation are to be collected from each of two offsite locations of the highest predicted annual average D/Q if milk sampling is not perfonned at all the required locations. Currently, broadleaf vegetation samples are collected at two indicator locations (N - 1.45 and SW - 1.0) and one control location (SW - 13.5). These indicator locations are near the site boundary in sectors where broadleafvegetation is available and D/Q is high. Therefore, no change to the broadleaf sampling program is required. Food product sample requirements of ODCM Table 3.12-1 requires that one sample of each principal class of food product be collected from any area that is irrigated with water in which liquid plant waste has been discharged. Of the gardens identified in the land use census, no gardens are located in any area that irrigates with water in which liquid plant wastes are discharged. Currently, food products are sampled from two locations (ENE- 9.0) and (E-4.2) when in season. The location ENE-9.0 is for pecans at time of harvest and location E-4.2 will continue to be a major source of food products sold to the public. The location E-4.2 had cucumbers which were collected from this location as a conservative measure. This garden does not meet the ODCM Table 3.12-1 requirements because the products are not irrigated by water in which liquid plant wastes have been discharged. 3

Calculated values for the associated X/Q and D/Q values for each controlling receptor location and pathway are included along with the receptor distances in the data tables of this land use census. The values used to determine potential dose due to radioactive effluent discharges are the highest calculated values based on annual average values. The following values are based on the original pre-operational and subsequent Comanche Peak 3 and 4 new build calculations which identified predominant wind direction, structures affecting potential release patterns, and area population. The annual average X/Q used for dose calculations is 3.30E-6, tritium X/Q is 4.36E-6, and the D/Q value is 3.34 E-8. All these values are conservative based on the 2017 Land Use Census data and therefore no changes are required in the dose calculation parameters as verified by the field data.

1. The municipal water system for the City of Granbury is supplied by surface water from Lake Granbury (location SW2) and ground water (location GW4). Each of these supplies is sampled. These samples are not required for compliance with Radiological Effluent Control 3/4.12.1, Table 3.12-1, because they are not affected by plant discharges.

2. This sample (location SW6) is representative of discharges from Squaw Creek Reservoir both down Squaw Creek and to Lake Granbury via the return line to Lake Granbury if used.

3. Plant potable water could be supplied by surface water from Squaw Creek Reservoir (location SW6) or ground water from onsite wells (location GW2) but is currently supplied by the Somerville County Water District from the Wheeler Branch Reservoir.

Each of these possible sources of water were sampled.

4. Ground water supplies in the plant site area are not affected by plant liquid effluents as discussed in CPSES FSAR Section 2.4.13. However, they are monitored for radioactivity IAW the requirements of the Radiological Effluent Control 3/4.12.1, Table 3.12-1.

5. Broadleaf sampling will be performed at the specified locations if milk samples are unavailable from any location.

6. Plant Potable Water (GW2) and Glen Rose (GW3) are supplied from surface water by the Somerville Water District from the Wheeler Branch Reservoir.

7. CPNPP Security Rifle Range (GWl) is supplied by a local Well.
