SUMMARY
The Energy Northwest Radiological Enviromnental Monitoring Program (REMP) evaluates the radiological impact of Columbia Generating Station operations on the environment in the airborne, direct radiation, waterbome, and ingestion pathways as specified in the Offsite Dose Calculation Manual (ODCM). Additional samples are collected at locations specified by the Site Certification Agreement (SCA) with the State of Washington Energy Facility Site Evaluation Council (EFSEC).
Energy Northwest's Columbia Generating Station is a 1230 MW commercial nuclear power plant that achieved initial criticality on January 19, 1984.
Prior to 1999, Columbia Generating Station was on an annual refueling cycle. The outages usually occurred from the middle of April to early June. In 1999, Columbia Generating Station transitioned to a 24-month refueling cycle. The plant operated continuously during 2002 with the exception of a forced outage February 14-24, 2002.
Samples of air, water, milk, soil, sediment, fish and garden produce were collected throughout 2002 and analyzed for radionuclides specific to plant operations. Radiation levels were also monitored continuously during the year with thermoluminescent dosimeters (TLDs).
Samples were collected in established areas near the plant and at other locations that could be affected by Columbia Generating Station effluents. This information was compared to samples taken in areas that were unlikely to be affected by plant operations. The 2002 REMP data was also compared to data collected during previous years of plant operation and to data collected prior to initial plant operation.
In 2002, Energy Northwest established an Independent Spent Fuel Storage Installation (ISFSI) facility. Radiation levels near the ISFSI were monitored continuously using TLDs. In addition to the two preoperational quarterly and annual TLDs, ten quarterly and annual TLDs were place on the fence upon completion of the ISFSI construction. The first of five dry storage casks was moved to the ISFSI in September 2002 and the fifth was placed at the facility in December.
Results from most samples collected during 2002 were below detection levels. Some analyses, such as gross beta in air and water, were above the detection level for nearly all samples. This is due to the low detection limit for the gross beta analysis and the abundance of beta-emitting radionuclides that occur naturally in the environment. Other results above detection levels, such as cesium-137 in soil and sediment, reflect the effect of past Hanford activities or fallout from Chernobyl and past nuclear weapons testing.
Tritium and other radionuclides in river/drinking, well, and discharge water were in concentrations below detectable levels in almost all samples. During 2002, Columbia Generating Station did not have a liquid radioactive waste discharge to the Columbia River.
The REMP analytical results and TLD results were demonstrated to be accurate through intercomparison programs, which are provided as part of the quality assurance activities, conducted during 2002. Such intercomparisons tested the performance of Energy Northwest's monitoring program to other monitoring programs using known radioactive standards. Energy Northwest's 2002 REMP ANNUAL REPORT 1-1
REMP analytical contractor performed well in the Environmental Measurements Laboratory (EML)
Quality Assessment Program, the Analytics, Inc. Cross Check Comparison Program, and other intercomparison studies conducted during 2002.
The analytical results from samples collected by the REMP in 2002 remained consistent with the results of environmental sarnples collected during the preoperational period and prior operational years. Based on the data, no significant new trends or changes in the environmental radiological levels around the plant were observed.

3.0 INTRODUCTION
3.0 INTRODUCTION
3.1 Site Description Energy Northwest's Columbia Generating Station is located in a sparsely populated shrub-steppe region within the Department of Energys Hanford Site in southeastem Washington. The plant is located approximately three miles west of the Columbia River and is surrounded on all sides by uninhabited shrub-steppe. The nearest population centers are the cities of Richland, Pasco and Kennewick, which are 12 miles south, 18 miles southeast, and 21 miles southeast, respectively.
The nearest privately owned lands are located approximately four miles east-northeast of the plant, across the Columbia River. The site has a bimodal wind pattern with winds primarily from the northwest and south directions.(21) Based on this, the focus of REMP sampling is the farming region east of the plant.
Because Columbia Generating Station is located on the Hanford Site, other potential sources of radioactive materials are in close proximity to Columbia Generating Station. For this reason, sampling locations near the plant provide useful information for separating the potential effects of Columbia Generating Station from those of other sources on the Hanford Site.
3.2 Program Background The REMP is designed to conform to the regulatory guidance of the Nuclear Regulatory Commission (NRC) as provided by Regulatory Guides 4.1 1) and 4.8,(2) including the Radiological Assessment Branch Technical Position. 3 ) In addition, the REMP also meets the requirements of 1 OCFR72.44(d)(2).
The quality assurance aspects of the program and the thermoluminescent dosimetry are conducted in accordance with Regulatory Guides 4.15(4) and 4.13.(5) The REMP also must adhere to the requirements of the Washington Energy Facility Site Evaluation Council (EFSEC),(6) the Columbia Generating Station Technical Specifications(7) and the Offsite Dose Calculation Manual (ODCM). 8 )
These requirements cover not only the environmental sampling and sample analysis aspects of the program, but also the reporting and quality assurance requirements of the program.
The preoperational phase of the program, which lasted from March 1978 until initial criticality in January 1984, provided a baseline of background environmental data. The variability in the background levels of radioactivity is due to differences in geologic composition, Chemobyl and nuclear weapons test fallout, meteorological conditions and seasonal changes.
A contract analytical laboratory was used for the analyses of REMP environmental samples.
Teledyne Brown Engineering Environmental Services has perforned the analysis of REMP samples since June 1986. Energy Northwest, until contracted to an outside vendor in 1996, processed the thermoluminescent dosimeters used in the REMP to assess the direct radiation. In 1997, Battelle Pacific Northwest National Laboratory became the environmental TLD processor.
The TLDs are processed at its Richland, Washington laboratory.
3-1 2002 REMP ANNUAL REPORT 3-1 2002 REMP ANNUAL REPORT
Any radiological effects of Columbia Generating Station on the environment must be distinguished from the normal variation in background radiation levels and from the effects of other sources of radioactive effluents in the area. The monitoring results obtained during each year of plant operation are compared to the preoperational data and data from previous operating years to determine whether a significant accumulation of station-produced radionuclides has occurred in the environment.
Quarterly averages of the results are also compared to the NRC non-routine reporting levels listed in the ODCM. In addition to evaluating the environmental concentrations against federal standards or limits, the REMP also compares the results to state standards! 12,13) The results are discussed and interpreted by comparing them to similar measurements made during the preoperational and previous operational periods, and to the detection capabilities associated with the current methods of analysis. The quality assurance and quality control aspects of the program are also discussed in this report.
3.3 Program Objectives The REMP provides a mechanism for determining whether the levels of radioactivity in the plant environs are within established limits and to ensure that the accumulation of radionuclides in the environment will not become significant as a result of station operations.
While in-plant monitoring programs are used to ensure that 10 CFR 20'9) and 10 CFR 50(10) criteria for releases of radioactive effluents are met, the REMP provides supplemental verification that the concentrations of radionuclides in the environment are not greater than anticipated from station operation.
2002 REMP ANNUAL REPORT 3-2
4.0 PROGRAM DESCRIPTION
4.0 PROGRAM DESCRTPTTON The Columbia Generating Station Offsite Dose Calculation Manual (ODCM) defines the requirement for the REMP. The sampling plan presented in Table 4-1 and 4-2 in this report shows which samples are required by the ODCM and the Site Certification Agreement (SCA). The table also provides a summary of the sample locations, collection frequency, and types of analyses performed. The methods of sampling and sampling frequencies utilized in the program have been determined by such factors as the half-lives and major exposure pathways for the radionuclides potentially released from the plant to the surrounding environment.
4.1 Sample Locations Ninety-five sample locations were included in the 2002 monitoring program. Eighty-eight indicator and two control (i.e., background) stations were located within a 10-mile (16-kilometer) radius of Columbia Generating Station. Three additional control stations and two indicator stations were outside the 10-mile radius from the station. Sample stations are listed in Table 4-2 by meteorological sector, sample media and approximate distance from the station. The numbers and locations of sample stations are based primarily on factors such as population distribution and meteorological conditions and also on station accessibility, security, and the requirements of applicable regulations. Other factors, such as the need to monitor locations that could be impacted by Columbia Generating Station operations, influence the location of REMP sampling sites.
The REMP sampling locations listed in Tables 4-1 and 4-2 are shown in Figures 4-1 and 4-2.
Figure 4-3 provides a more detailed map of sampling locations in the Sunnyside/Grandview area.
Figure 4-4 shows the relative locations of the storm drain outfall and pond (Station 101) and the Sanitary Waste Treatment Facility (Station 102). Also shown are the cooling tower sediment disposal area (Station 1 19B and Station 1 19-Control) and the spray pond drain field (Station 120),
which are special interest stations.
4.1.1 Independent Spent Fuel Storage Installation (ISFSI)
During 2002, Energy Northwest constructed the Independent Spent Fuel Storage Installation (ISFSI) to provide additional storage of spent fuel. The spent fuel is stored in HI-STORM dry storage casks located approximately 500 meters north-northwest of the reactor building. Five dry storage casks were placed in the installation during 2002. Cask placement took place on the following dates: 09/20; 10/07; 10/28; 11/18, and 12/09.
REMP monitoring of the ISFSI consists of a set of quarterly and annual TLDs located at 10 stations on the isolation fence surrounding the casks. In addition, two other stations are located on other fence lines. Station 121 is located on a fence line approximately 200 meters north of the turbine building and Station 122 is located on the fence approximately 30 meters north of the ISFSI. Figure 4-5 shows the ISFSI location in relation to Columbia Generating Station.
Figure 4-6 shows the location of the 10 TLD stations located around the ISFSI. These satisfy the monitoring requirements of 10CFR72.44(d)(2).
4-1 2002 REMP ANNUAL REPORT 4-1 2002 REMP ANNUAL REPORT
4.2 Land Use Census The land use census for areas within five miles of Columbia Generating Station was performed in August. The objectives of the land use census are to identify the locations of the nearest milk animal, residence, and garden greater than 500 ft2 producing broadleaf vegetation. This information is used to determine whether any site located during the census has a calculated dose or dose commitment greater than the sites currently monitored for the same exposure pathway. If a new location with a higher dose commitnent was found, routine sampling of that dose pathway would be initiated at that new site.
The results of the 2002 land use census are presented in Table 4-3. The only change from the 2001 land use census observed was the lack of gardens in the ENE and ESE sectors. No milk animals were located within the 5-mile radius. The nearest milk location was located 7.2 miles east-southeast of Columbia Generating Station.
4.3 Sampling Methods Energy Northwest personnel collected environmental samples in accordance to the program plan in Table 4-1. Documented procedures for sample collection and TLD handling are contained in departmental instruction manuals. The analytical contractor prepares and maintains the sample analyses procedures. Energy Northwest receives copies of the analytical procedures used.
The following sections describe the sampling and preparation methods.
4.3.1 Direct Radiation During 2002, thermoluminescent dosimeters (TLDs) were used to determine the direct radiation levels at seventy-two (72) monitoring locations listed in Table 4-1. Control station TLDs (background) are located at Station 9A in Sunnyside and Station 119-Control, 0.2 mile south-southeast of the station. The remaining TLDs served as indicator TLDs throughout the year.
Two sets of TLDs placed approximately three feet above ground were employed at each location.
One set of TLDs was exchanged on a quarterly basis (Quarterly TLDs) and the other was exchanged on an annual basis (Annual TLDs). Exposure received by the field TLDs during transport to the TLD sites was monitored by a set of trip control dosimeters that accompanied the field dosimeters to and from the field locations. Another set of TLDs - building controls - were used to determine the exposure of the TLDs at the controlled storage location. The TLD exposure during transport to and from the field was determined from the difference between the building control results and the trip control results.
Direct radiation levels were measured on Harshaw Model 8807 TLDs and processed by Battelle Pacific Northwest National Laboratory (PNNL) on a Harshaw Model 8800 Hot Gas Reader. This reader is calibrated weekly and immediately prior (same day) to processing environmental TLDs.
The reader is calibrated in generic units (gU) using calibration dosimeters irradiated to known exposures of Cs-137. Each group of environmental TLDs that is processed includes "blank" unirradiated TLDs and processing control dosimeters irradiated by PNNL to a known quantity of Cs-137. In addition, "blind spiked" irradiated TLDs are submitted by EnergyNorthwest for 2002 REMP ANNUAL REPORT 4-2
processing along with the environmental TLDs. The processing results from these QA TLDs are used to demonstrate reader performance during environmental TLD processing.
A file containing "raw" element readings in gU is generated when the Harshaw TLD reader processes the environmental TLDs. This file is used by Energy Northwest to calculate environmental doses. A relative response factor of 1 gU/niR is applied to convert the TLD response to the Roentgen equivalent reading, then background and transit doses measured by control TLDs are subtracted. Doses are reported in mrem and no correction to dose equivalent is applied.
The exposure values deterrnined for calibration dosimeters, as well as the exposures of QA dosimeters (processing control dosimeters), are based on a National Institute of Standards and Technology (NIST) traceable Cs-I 37 source. The exposure values for the audit dosimeters (spiked dosimeters) are based on the calculated field strength of an Energy Northwest Cs-137 source.
Ionization chamber measurements made during TLD exposure are used to confirm the calculated exposure. If the calculated exposure and the ionization chamber reading differ by 5% or more, an investigation is performed to resolve the difference.
Two Reuter Stokes pressurized ionization chambers (PICs) provide additional capability for measuring direct radiation exposure. These units are no longer part of the routine monitoring program, but they may be used in special monitoring situations and are maintained as back-up monitoring systems.
4.3.2 Airborne Particulate/Iodine Airparticulate and air iodine (1-131) samples were obtained through the use of portable, low volume (1.5 cfm) constant flow-rate sampling units at each of 12 locations. The samples drawn at Station 9A (Figure 4-3) were considered control samples; the ones drawn at the other locations (Figure 4-1) were indicator samples. Air particulate sanples were collected by drawing air through a 47-mm diameter glass fiber filter. Air iodine samples were collected by drawing air through a 57-mm diameter TEDA impregnated charcoal cartridge. The particulate air filter and charcoal cartridge were placed in tandem, particulate filter first, in a holder that attached to the air inlet of the sampler unit. The sampler units were placed in ventilated metal weatherproof housings mounted on elevated platforms at each air sample location. The filter media are changed weekly and shipped to the analytical contractor for analysis within one or two days of collection.
4.3.3 Water There were eight locations for water sampling in 2002: two for the evaluation of river/drinking water, one for plant discharge water, three for groundwater, one for the storm drain water, and one for sanitary waste water. One river/drinking water location, Station 26, was used for evaluation of the plant intake water. This sample location is also a drinking water sample since Columbia Generating Station draws its drinking water from the intake water. It is the river/drinking water control sample because of its location upstream of the plant discharge. Station 29 was used to evaluate the water at the nearest drinking water location, the Richland Water Treatment Plant. This station, 1 1 miles downstream of the discharge, is the indicator station for river/drinking water.
2002 REMP ANNUAL REPORT 4-3
The ODCM requirement for a downstream water sample "near but beyond the mixing zone" was met by sampling water from Station 27, the cooling tower discharge line to the Columbia River.
This sample reflects the radioactivity present in the plant discharge prior to any river dilution, rather than the concentrations that would be found after dilution in the mixing zone. Water is drawn at this location because it was not feasible to perform flow-proportional composite sampling in the mixing zone area of the river downstream from the plant discharge point. The Station 27 sample is also an indicator sample.
Composite samplers are installed at the Columbia River pumphouse to monitor plant intake water (Control Station 26), and the cooling tower discharge line (Station 27). There is also a composite sampler at the other drinking water location (Station 29). The samplers collect 25-ml aliquots of water at regular intervals of time for Stations 26 and 29 or discharge flow for Station 27. Routine analysis of these samples are gross beta and gamma with tritium samples composited and analyzed quarterly.
Three wells within the vicinity of Columbia Generating Station are used as groundwater sampling locations. These include a deep well on the Columbia Generating Station site (0.1 mile north of the Reactor Building) and two wells on the WNP-l site (1.2 mile downgradient from Columbia Generating Station). Water from the Columbia Generating Station well can be used as a backup source for drinking and fire protection. Water from the WNP-1 wells supplies drinking and fire protection water for the WNP-1 site. Although none of these wells draw from the unconfined aquifer, they are considered indicator samples. Quarterly grab samples were collected from each of these wells. One gallon (3.8 liters) was collected from each well for gamma analysis and one liter was drawn for tritium analysis.
Water samples were collected from the storm drain outfall (Station 101) using a flow-proportional composite sampler. These samples were analyzed for gross beta, gamma and tritium.
Since April of 1997, the Sanitary Waste Treatment Facility has been receiving sanitary waste from the DOE 400 Area. Energy Northwest maintains a flow meter and a composite sampler on the 400 Area sewer line just above where the 400 Area/Plant Support Facility (PSF) intertie is located. This sampler (REMP Station 1 02A) takes a flow-proportional sample that was composited and analyzed monthly for gross alpha, gross beta, gamma and tritium as required by EFSEC Resolution No.
300.(16) Monthly samples were also collected at the SWTF headworks structure (Station 102B). In the fall of 2002, a composite sampler was placed in service at the headworks to replace grab sample collection. These samples were analyzed for gross alpha, gross beta, gamma and tritium. Until September 2002, two samples collected prior to each discharge were required, which were collected at the discharge weir of the south pond (Station 102C). Those samples were analyzed for gross alpha, gross beta, gamma and tritium.
4.3.4 Soil As required by the Site Certification Agreement (EFSEC Resolution No. 260(6)), an annual soil sample was collected at indicator stations 1, 7, 21 and 23. One sample was collected at the control location, Station 9A (Figure 4-3).
2002 REMP ANNUAL REPORT 4-4 4-4 2002 REMP ANNUAL REPORT
Each sample was collected from an area of approximately one square foot to a depth of approximately one inch. Approximately two kilograms of soil were collected in each sample.
Soil samples were shipped to the analytical contractor after collection and analyzed for gamma activity.
If the gamma isotopic analysis indicates that cesium levels in any of the indicator samples exceeds ten (10) times the level in the control sample, a strontium analysis is performed on the sample(s).
Strontium analysis was required for Station 1 during 2002.
4.3.5 Sediment The collection of river sediment samples occurred in March and again in October. The collection of the upstream sediment sample (Station 33) was from a location approximately two miles upriver from the plant discharge. The downstream sample (Station 34) was collected approximately one mile downstream of the plant discharge. Each sample consisted of approximately two kilograms of the shallow surface sediment scooped from below the waterline. The samples were shipped to the analytical contractor for gamma analysis.
A two-kilogram sample of dried cooling tower sediment was collected from the sediment disposal cell (Station 1 19B) within thirty days of the completion of cleaning the cooling towers. In 2002, the cooling towers were cleaned once in July, hence, only one sample was collected for gamma spectrometry analysis.
4.3.6 Fish The annual fish sampling was performed in late September and early October. Fish samples collected from the Columbia River (Station 30 in Figure 4-1) were indicator samples, whereas, the fish collected on the Snake River (Station 38 in Figure 4-2) were control samples.
Three separate fish samples, consisting of an anadromous species such as salmon, and two other species generally considered edible or potentially edible (such as carp, catfish and whitefish) were collected at each location. The fish were collected using electroshock technique except for the samples of the anadromous species, which were collected from the Ringold Fish Hatchery on the Columbia River and at the Lyons Ferry Fish Hatchery on the Snake River. The fish were filleted to obtain approximately one kilogram of edible flesh per sample. The fillets were placed in clean plastic bags and frozen until shipment to the analytical contractor for gamma analysis. Fish are sampled annually unless elevated radiation levels related to plant operations are observed, in which case sampling is conducted semiannually.
4.3.7 Milk Milk samples were collected monthly January through March and October through December and twice a month during the spring and summer months when cows were likely to be grazing or on fresh feed. Enough raw milk was collected from each sampling location to obtain a one-gallon sample after the cream had been skimmed off. The samples were refrigerated overnight and the cream skimmed off the next morning. The milk samples were chilled and shipped to the analytical contractor within a day of collection for gamma and I-131 analyses.
4-5 2002 REMP ANNUAL REPORT 4-5 2002 REMP ANNUAL REPORT
Routine samples were collected from two indicator locations (Stations 36 and 64) across the Columbia River in Franklin County. Milk samples were also collected at one indicator station (Station 9B) in the Sunnyside/Grandview area (Figure 4-3). Station 9B in Sunnyside serves as an indicator station because a portion of the feed for the cows at that location is hay from Franklin County north of Pasco and downwind from Columbia Generating Station. That factor makes it unsuitable for use as a control location. Beginning in August 1998, samples of feed grown at Station 9B were collected monthly as a substitute for the lost control station, which ceased operation in March 1998. These samples of feed have gamma and 1-131 analyses performed on them. Other dairies in the area have been checked for suitability as a new control location for milk collection and were eliminated due to their use of feed grown in Franklin County. No control station currently exists for milk samples.
4.3.8 Garden Produce Samples of local garden produce were collected monthly from April to September when the produce was readily available. When possible, three types of produce samples (a root crop, fruit, and a leafy vegetable) were collected at each location. The indicator saMples were collected from a region in a predominant downwind direction (Station 37 in Figure 4-2) where crops are irrigated with Columbia River water. The control samples were obtained from produce stands in the Sunnyside area (Station 9C in Figure 4-3), the direction least likely to be affected by plant effluents.
Apples were collected in September from Station 91, the Rio Vista Farms orchard, which is irrigated with Columbia River water. All samples are shipped to the analytical contractor for gamma analysis.
4.4 Analytical Procedures Described below are the analytical procedures used for analysis of the 2002 REMP samples.
Teledyne Brown Engineering Environmental Services performed all sample analyses for the REMP during 2002.
4.4.1 Gross Beta Activity on Particulate Filters The particulate filters were counted in a gas flow-proportional counter after a delay of five or more days to allow for the radon-222 and radon-220 (thoron) daughter products to decay. An unused air particulate filter was counted as the blank with each weekly set of filters.
4.4.2 Measurement of Gamma Emitters A shielded HPGe detector system was coupled to a computer-based data acquisition system which performed pulse height and gamma energy analysis. The information collected about each peak was compared to a library of known peaks. Isotopic identification was performed, as was the radioactivity calculation, using the appropriate fractional gamma ray abundance, half-life, detector efficiency, and net counts in the peak region.
Milk and Water A one-liter Marinelli beaker was filled with a representative aliquot of the sample. The 2002 REMP ANNUAL REPORT 4-6
sample was then counted for at least 1000 minutes (16.7 hours8.101852e-5 days <br />0.00194 hours <br />1.157407e-5 weeks <br />2.6635e-6 months <br />) with a shielded high purity germanium (HPGe) detector coupled to a personal computer (PC) based data acquisition system which performs pulse height analysis.
Fnod,gtuff As much of the edible portion of the sample (fish or meat) as possible was placed into a tared Marinelli beaker and weighed. The sample was then counted for at least 1000 minutes (16.7 hours8.101852e-5 days <br />0.00194 hours <br />1.157407e-5 weeks <br />2.6635e-6 months <br />).
Vgetttion As much sample as possible was placed in a tared one-liter Marinelli beaker and counted for approximately 1000 minutes (16.7 hours8.101852e-5 days <br />0.00194 hours <br />1.157407e-5 weeks <br />2.6635e-6 months <br />). The sample was not dried prior to counting, so the results are given in terms of wet weight.
Soils nnd Sediments A large quantity of the sample was dried at a temperature below 100 C. As much sample as possible was loaded into a tared 300 cc Marinelli beaker and weighed. The sample was then counted for at least 360 minutes (6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />).
Charcoal Cnrtridges (Air Todine)
Charcoal filters were counted up to five at a time, with one positioned on the face of a HPGe detector and up to four on the side of the HPGe detector. Each HPGe detector is calibrated for both positions. The detection limit for a charcoal cartridge was determined (assuming no positive I-13 1) uniquely from the volume of air which passed through it. In the event that iodine-131 was observed in the initial counting of a set, each charcoal cartridge in the set would then be positioned separately on the face of the detector and counted.
Air Particnlate Filterc Air particulate filters from each field station were retained and are composited quarterly.
The filters were aligned one in front of another and counted for at least 360 minutes (6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />).
4.4.3 Gross Beta Activity in Water An one-liter aliquot of each sample was evaporated to a small volume in a beaker and rinsed into a 2-inch diameter stainless steel planchette that is stamped with a concentric ring pattern to distribute residue evenly. The final evaporation of the sample is done under heat lamps. Residue mass was determined by weighing the planchette before and after mounting the sample. The planchette was counted for beta activity on an automatic proportional counter. The results were calculated using empirical self-absorption curves, which allow for the change in effective counting efficiency caused by the sample residue mass.
2002 REMP ANNUAL REPORT 4-7
4.4.4 Iodine-131 in Water Two liters of sample were first equilibrated with a stable iodide carrier. A batch treatment with anion exchange resin was used to remove iodine from the sample. The iodine was then stripped from the resin with sodium hypochlorite solution, reduced with hydroxylamine hydrochloride, and extracted into carbon tetrachloride as free iodine. It was then back-extracted as iodide into a sodium bisulfite solution and precipitated as palladium iodide. The precipitate was weighed for chemical yield and mounted on a nylon planchette for low-level beta counting. The chemical yield was corrected by measuring the stable iodide content of the water with a specific ion electrode.
During 2002, this procedure was used only on intercomparison samples, since the doses calculated by means of ODCM methodology for the consumption of drinking water did not exceed one millirem per year.
4.4.5 Tritium in Water The analysis of tritium in water was performed utilizing liquid scintillation. Liquid scintillation requires 10 milliliters of water mixed with 10 milliliters of liquid scintillation "cocktail." The mixture was then counted in an automatic liquid scintillation detector.
4.4.6 Strontium-89 and 90 in Water, Milk and Soil During 2002, strontium analysis was required for soil samples at Station 1, Station 7, and Station
- 23. No strontium analyses were required for any water or milk sample. It was also used in laboratory intercomparison programs for water and sediment analyses. The techniques used to analyze for strontium in the various media are described below.
Wnter Stable strontium carrier was added to one liter of sample and the volume was reduced by evaporation. Strontium was precipitated as Sr(NO3)2 using fuming (90%) nitric acid. A barium scavenge and an iron (ferric hydroxide) scavenge were performed by addition of stable yttrium carrier and allowing a minimum five-day period for yttrium ingrovth. Yttrium was then precipitated as hydroxide, dissolved and reprecipitated as oxalate. The yttrium oxalate was mounted on a nylon planchette and was counted in a low-level beta counter to infer Sr-90 activity. Strontium-89 activity was determined by precipitating SrCO3 from the sample after yttrium separation. This precipitate was mounted on a nylon planchette and was covered with an 80 mg/cm2 aluminum absorber for low-level beta counting.
Aik Stable strontium carrier was added to 1-liter of sample and the sample was first evaporated, then ashed in a muffle furnace. The ash was dissolved and strontium was precipitated as phosphate, then was dissolved and precipitated as SrNO3 using fuming (90%) nitric acid.
A barium chromate scavenge and an iron (ferric hydroxide) scavenge were then performed.
Stable yttrium carrier was added and the sample was allowed to stand for a minimum of 5 days for yttrium ingrowth. Yttrium was then precipitated as hydroxide, dissolved and then re-precipitated as oxalate. The yttrium oxalate was mounted on a nylon planchette and 2002 REMP ANNUAL REPORT 4-8
counted in a low-level beta counter to infer Sr-90 activity. Strontium-89 was determined by precipitating SrCO3 from the sample after yttrium separation. This precipitate was mounted on a nylon planchette and covered with an 80 mg/cm aluminum absorber for low-level beta counting.
Soil and Sediment The sample was first dried under heat lamps and an aliquot was taken. Stable strontium carrier was added and the sample was leached in hydrochloric acid. After filtering the mixture, strontium was precipitated from the liquid portion as phosphate. Strontium was precipitated as Sr(NO3)2 using fuming (90%) nitric acid. A barium chromate scavenge and an iron (ferric hydroxide) scavenge were then performed. Stable yttrium carrier was added and the sample was allowed to stand for a minimum of five days for yttrium ingrowth. Yttrium was then precipitated as hydroxide, dissolved and reprecipitated as oxalate. The yttrium oxalate was mounted on a nylon planchette and counted in a low-level beta counter to infer strontium-90 activity. Strontium-89 activity was determined by precipitating SrCO3 from the sample after yttrium separation. This precipitate was mounted on a nylon planchet and covered with an 80 mg/cm2 aluminum absorber for low-level beta counting.
4.4.7 Iodine-131 in Milk Two liters of sample were first equilibrated with stable iodide carrier. A batch treatment with anion exchange resin was used to remove iodine from the sample. The iodine was then stripped from the resin with sodium hypochlorite solution, reduced with hydroxylamine hydrochloride, and extracted into carbon tetrachloride as free iodine. It was then back-extracted as iodide into sodium bisulfite solution and precipitated as palladium iodide. The precipitate was weighed for chemical yield and mounted on a nylon planchet for low-level beta counting. The chemical yield was corrected by measuring the stable iodide content of the milk with a specific ion electrode.
4.5 Data Analysis Methods Since mid-1 984, the results of the REMP analyses have been presented as net results calculated from the gross or total counts determined for each radionuclide minus the background counts of the counting or detection instrument. Consequently, for several sample types, the results range from negative to positive numbers. This manner of presenting environmental data prevents the bias and loss of individual results inherent in the use of "less than" (<) values, where the "less than" numbers can have a variety of meanings, such as "less than the lower limit of detection (LLD)."
A listing of the LLDs determined for each analysis is provided in Table 4-4 as a reference when reviewing the sample results.
Plots of the sample results versus time are used to represent the results for analyses such as gross beta on air particulate filters, where the results are normally above the lower limits of detection. In such cases, the indicator station results are plotted with the control station results for easy comparison. Other data analysis techniques, such as frequency distributions, are also used to represent the data and to determine whether trends that could be attributed to Columbia Generating Station operations are evident. Thermoluminescent dosimeter (TLD) data is presented in terms of 2002 REMP ANNUAL REPORT 4-9
the net mrem/day exposure rate. These results are determined from the total exposure (in mrem) calculated for each TLD from its total thernoluminescent output minus the TLD background, minus any transit (or trip) exposure received during distribution and retrieval, and divided by the number of days the TLD was in the field. Frequency distributions and graphs of TLD data by meteorological sector and distance from the plant are used to interpret trends in the results.
The TLD data summaries include the term "standard error." The standard error, which is the estimate of the precision of the mean, is used for the means of quarterly and annual data and is an indicator of the uncertainty associated with the results. The mean results of the quarterly TLDs are compared with the results of annual TLDs and expressed as a ratio by dividing the quarterly results by the annual result.

The term, river/drinking water," instead of, "surface/drinking water," is uscd throughout this report because the surface water is taken from the Columbia River. Station 26, Columbia Generating Station akeup water intake from the Columbia River is both an upstream surface, or river, water sample and the drinking water control sample location. The Station 29 sample is a downstream dinking water sample. The Station 27 sample, which is drawn from the plant discharge line, is taken in place of a "downstream" water sample near but beyond the mixing zone. It reflects the radioactivity present in the plant discharge prior to any river dilution.
he SCA requires two drinking water locations downstream from the plant discharge and requires sampling from the plant intake and discharge water. Only one drinking water station is now sampled after DOE closed the intake at the 300 Area (Station 28) in 1998. Station 101,the stormdrain pond, and Station 102, the Sanitary Waste Treatmcnt Facility, are unique sampling locations.

Within a five-mile radius of the plant, only 4.5 sq. miles of the land in the sixteen meteorological sectors is privately owned farmland. The remainder of the land is on the federally owned Hanford Site. Only those sectors containing points of interest are presented here. The WNP-1 and WNP-4 sites are not part of the five-mile land use census due to the fact that the REIP sample stations were originally sited to incorporate all three sites.

5.0 RESULTS AND DISCUSSION
5.0 RESULTS AND DISCUSSION Radiological Environmental Monitoring Program (REMP) sample analyses were performed by Teledyne Brown Engineering Environmental Services in Knoxville, Tennessee. Battelle Pacific Northwest National Laboratory in Richland, Washington processed the enviromnental TLDs.
Table 5-1 presents the means and ranges of selected 2002 results for each type of sample collected and Table 5-3 provides a summary of detectable results. The means and ranges of preoperational and previous operational data are also included in the table for comparison. The data tables of 2002 results comprise a separate volume that is available upon request.
The analytical data for the preoperational period and the first six months of 1984 included "less than" (<) designations for results below the actual LLD, the contractual LLD, or the two-sigrna error, depending upon the convention employed by the analytical contractor. Consequently, the data averages using "less than" values are biased high. Since mid-1984, REMP data have been reported as net results (i.e., the detector counting background is subtracted from the gross results).
The primary focus of the REMP is to determine whether Columbia Generating Station operations had an impact on the environment. The 2002 results are compared in this report to the results from the preoperational period and to results from previous years of Columbia Generating Station operation. Results are also compared to state and federal regulatory limits. The use of "less than" values, rather than net results, during the preoperational period and during the first year of operation, and the impact of the 1986 Chemobyl accident on environmental radiation levels affect the interpretation of the 2002 measurements relative to previous measurements. Some of the parameters considered in the evaluations discussed in this report are the means, ranges and standard deviations or standard errors of the results. Comparative plots and frequency distributions of the data are some of the tools that have been employed in the interpretation of the 2002 REMP data.
The analytical results for the REMP sampling locations during 2002 are very similar to the results reported for previous years. The 2002 annual and quarterly TLD results were also very much like those observed previously. No significant trends indicating an environmental impact or unexpected change in the environmental concentrations or exposure rates at REMP monitoring stations were observed.

5.1 Direct Radiation Environmental radiation exposure rates at near plant and remote stations, as deternined using thermoluminescent dosimeters (TLDs), remained consistent with data from previous years.
Figure 5-1 presents a plot of the 2002 mean quarterly TLD results for each of the sixteen meteorological sectors at the property boundary of the plant

This indicates that there were no significant directional effects observed in the 2002 TLD results. The environmental radiation exposure rates, as determined by TLDs, are summarized in Tables 5-4 and 5-5.

Exposure rates from the inner circle of TLDs are presented in Figure 5-2. The exposure rates observed in the 2002 inner circle data closely follows the preoperational mean in most sectors. Station 24 of the inners circle had a result of 0.55 during the first quarter. Subsequent investigation revealed no evidence of abnormal radiation levels at that station. The result presented for the SE sector is the mean without the first quarter result of Station 24.

Since the preoperational measurement phase, the results for this location have exceeded the results for all other locations. Variations in the soil and underlying rock composition most likely account for localized differences such as those shown in the TLD results for Station 46. The mean of the four quarterly results for Station 46 was 0.29 mrem/day, with a range of 0.28 mrem/day to 0.31 mrem/day.
Frequency distribution plots of the 2002 quarterly TLD results are presented in Figure 5-4. The plots varied slightly from quarter to quarter, with 0.25 mrem/day being the most frequent result, followed by 0.24 mrem/day and 0.23 mremtday. The most frequent result for the period 1984 to 2001 was 0.25 mrem/day, followed by 0.26 mrem/day and 0.24 mrem/day. The frequency distributions for the previous operational TLD results are shown in Figure 5-5.
Presented in Table 5-6 is a comparison of the 2002 annual and mean quarterly TLD results. The 2002 annual TLD results are generally 5-10% lower than the mean quarterly results because of signal fade. This difference is not significant, in light of the variability commonly observed in TLD results. In most cases, the annual result is within the uncertainty associated with the quarterly TLD results.

5.2 Airborne Particulate/Iodine The 2002 mean weekly gross beta on particulate filter results for the inner ring indicator stations (within three miles) for Columbia Generating Station are plotted in Figure 5-6. The gross beta in air results for 2002 were within the ranges observed during the preoperational period and during previous operational periods, as shown in Table 5-1. The similarity between results from near-plant locations and those from remote locations can be seen in comparing Figure 5-6 to Figure 5-7. The results for the control location (Station 9A) also have a similar pattern to the remote and near-plant indicator locations. As observed previously, gross beta levels increased during periods of temperature inversion occurring in the fall and winter months. Gross beta results plotted over a period of several years show a cyclic pattern of fall and winter increases. The increase, which was evident in the results of all the air-sampling locations, is due to an increase in radon and radon daughter concentrations during the fall and winter temperature inversions.
The quarterly gamma analyses of the particulate filter composites indicated only the presence of two naturally-occurring radionuclides, beryllium-7 and potassium-40, at levels above detection limits at indicator locations and the control location. All iodine-131 in air results for 2002 were below the LLD.

5.3 Water The gross beta results for river/drinking water were within the normally observed ranges. These results were less than the eight picocuries/liter (pCi/l) level at which a strontium analysis is performed to verify compliance with the Washington State drinking water standard for strontium-90. The 2002 gross beta concentrations in river/drinking water, relative to the state annual average concentration limit,(i) compare well to the averages from previous periods. Gross beta levels for 2002 averaged 2.1 pCi/l at Station 26, the control station, and 1.6 pCi/I at Station 29 approximately 1 1 miles downstream from the discharge.
The gross beta levels in the discharge sample (Station 27) reflect the concentrations of radionuclides that occur naturally in the environment, principally potassium-40, and any radionuclides from upstream sources of past Hanford activities present in the makeup water. The water discharged from Columbia Generating Station was typically concentrated 5 to 10 cycles. The discharge sample results are representative of the radioactivity present in plant discharges before any mixing with river water occurs. All results, which averaged 9 pCi/l, were below the Washington Department of Health (WDOH) investigation level of 75 pCi/l, which is the point at which Energy Northwest would notify WDOH of the result.
The tritium levels in the river/drinking water and groundwater for 2002 were below the nominal detection level of 300 pCi/I and were comparable with results obtained for prior years.
2002 REMP ANNUAL REPORT 5-6 l
5-6 2002 REMP ANNUAL REPORT
The mean tritiun concentration in discharge effluent during 2002 continued to be in the same low ranges observed since 1989. Columbia Generating Station has reduced the volume of liquid radioactive waste discharges from a high of over three million gallons in 1993 to no liquid radioactive waste discharges since September 1998. This has resulted in a comparable decline in tritium levels from a high of 12,000 pCi/I in 1993 to less than the detection level. In 2002, all results were below the detection level of 300 pCiI and far below the 20,000 pCi/I drinking wvater standard.
Non-routine analyses of the drinking water samples include strontium-90 and iodine-131 analyses.
Strontium-90 analysis is required when the gross beta activity exceeds either eight pCi/liter or ten times the mean of the previous three months' activity for a specific location. Iodine-131 analysis is required when the dose calculated for the consumption of water exceeds one millirem per year.
During 2002, neither of these analyses was required.
There were no detectable nuclides in the river/drinking, plant discharge or ground water samples during 2002.
5.4 Soil The results of the gamma spectrometry performed on soil samples in 2002 indicated detectable cesium-137. The cesium-137 results ranged from 1.1 picocuries/kilograrn (pCi/kg) to 422 pCi/kg at the indicator stations. The result for cesium-137 at the control station was 16 pCi/kg. As shown in Table 5-1, cesium-137 levels in the soil samples were well within the range observed during preoperational and previous operational sampling. The gamma spectrometry results for the soil samples did not indicate any impact from Columbia Generating Station operations on the environment.
Strontium analysis was required for Station 1 and the result was 74 pCi/kg. The strontium-90 level observed at the station is consistent with levels typically found on and near the Hanford Site.('4 )
Aside from cesium-137 and strontium-90, the only radionuclides detected in the samples were potassium-40, radium-226 and thorium-228. These are part of the natural radioactivity typically found in soils.
5.5 River Sediment The results of gamma spectrometry of river sediment indicated that, aside from the naturally occurring radionuclides (actinium-228, potassium-40, radium-226, thorium-228, uranium-235),
cesium-137 was detected both upstream (Station 33) and downstream (Station 34) of the plant. The cesium-137 concentrations in the upstrearn samples were 43 pCi/kg and 55 pCi/kg dry weight. The concentrations of cesium-137 in the downstream samples were 226 pCi/kg and 288 pCi/kg dry weight. This radionuclide has been detected in similar quantities in both preoperational samples and operational samples and has been previously identified as a component of the Columbia River sediment originating from operation of the old Hanford Site reactors.(15) Europium-152 was also detected in the fall downstream sample with a result of 56.8 pCi/kg dry. This is consistent with levels found in this section of the Columbia River. 22 )
5-7 2002 REMP ANNUAL REPORT 5-7 2002 REMP ANNUAL REPORT
5.6 Fish The gamma spectrometry results of fish samples collected in the vicinity of the Columbia Generating Station discharge and at the control location on the Snake River were below detection limits, except for potassium-40, a naturally-occurring radionuclide.
5.7 Milk There were no detectable iodine-131 results for 2002. All gamma spectrometry milk sample results were less than the detection limits, except for potassium-40, which is a naturally occurring radionuclide.
Since August 1998, samples of feed grown by the owners of the dairy at Station 9 have been collected as a substitute for the control station. No dairy in the area of the control was located that did not use some feed grown downwind of the plant as supplemental feed. No radionuclides were detected in the feed samples collected during 2002 other than the naturally occurring beryllium-7, potassium-40, and thorium-228.
5.8 Garden Produce The gamma isotopic analysis results for all root crops, fruit and leafy vegetables collected in 2002 were below detection limits, other than potassium-40, which occurs naturally.
5.9 Special Interest Stations The storm drain pond and the Sanitary Waste Treatment Facility (SWTF) were incorporated into the routine sampling schedule in 1992. In 1995, the cooling tower sediment disposal area was added. Thermoluminescent dosimeters were placed around the spray pond drainfield (Station 120) in June 1995. TLDs were hung in the vicinity of the planned Independent Spent Fuel Storage Installation (ISFSI) during the first quarter of 1998 to collect background data and an additional ten TLDs were hung on the ISFSI fence after construction was completed in 2002. Discussions of the results from each of the locations are provided in the following sections.
Until incorporated into the REMP, the sediment samples collected during previous years at the storm drain outfall and the SWTF were analyzed by Energy Northwest. The SWTF sediment samples were analyzed wet so the results were in terms of wet weight instead of the dry weight concentrations determined by Teledyne. Consequently, direct comparison of the wet sample results with the dried sample results is difficult since the percent solids can vary from sample to sample.
5.9.1 Storm Drain Pond (Station 101)
The storm drain pond is located approximately 1500 feet northeast of Columbia Generating Station.
Water is conveyed to the pond by means of an 18-inch diameter pipe that discharges into a 300-foot long earthen channel that leads to a 100-foot diameter pond. The pond is a shallow, unlined percolation/evaporation basin.
2002 REMP ANNUAL REPORT 5-8 5-8 2002 REMP ANNUAL REPORT
Tritium was detected in many of the outfall water samples during 2002. The range for detectable tritium results at the outfall was from 180 pCi/i to 14000 pCiI and averaged 2529 pCill. Detectable gross beta activity at the outfall averaged 4.6 pCi/l with a range of 2 to 7.1 pCi/l. Other than tritium, there were no detectable nuclides found in storm drain pond samples in 2002. The higher result in tritium at the end of the year was caused by an increase in tritium being discharged through the Reactor Building stack.
5.9.2 Sanitary Waste Treatment Facility (Station 102)
The Sanitary Waste Treatment Facility (SWTF) is located approximately 0.4 miles south-southeast of Columbia Generating Station. The facility processes the sanitary waste from Columbia Generating Station, the WNP-1 and WNP-4 sites, the Kootenai Building and the Department of Energy 400 Area (since April 1997). Discharge standards and monitoring requirements for the SWTF are established in EFSEC Resolution No. 300.("6) Until April 1992, the SWTF sediment was sampled semiannually and analyzed in the Energy Northwest radiation laboratory and the radionuclide concentrations were given in terms of wet weight. Since that time, the samples have been sent to the analytical contractor where they are dried prior to analysis and the results reported in pCi/kg dry weight. Sediment samples are now collected annually.
The average gross beta result for wastewater sampled prior to discharge to the percolation beds was 59 pCi/l. Monthly composite water samples of the 400 Area effluent had gross beta results ranging from 20 pCi/l to 39 pCi/I and averaged 28.8 pCi/l.
Prior to discharge samples and 400 Area effluent samples were also analyzed for gross alpha.
There were no detectable gross alpha results for 2002.
Due to contributions from the 400 Area effluent, tritium concentrations in SWTF samples continued to be higher than might otherwise be expected. The 400 Area draws part of its water from the unconfined aquifer that is high in tritium due to historical chemical separation processes at the 200 East Area on the Hanford Site. In 2002 the mean for tritium in the 400 Area effluent (Station 102A) was 3280 pCi/I and ranged from 2480 pCi/I to 4710 pCi/l. The mean at the headworks (Station 102B) was 785 pCi/l and the results ranged from 104 pCi/I to 1450 pCi/l.
Tritium in the pond (Station 102C) averaged 585 pCi/l and ranged from 540 pCi/l to 630 pCi/l.
Gamma analysis was done on all water samples collected at the SWTF. There were no detectable nuclides gamma results other than natural K-40 in the 2002 SWTF samples.
Gamma analysis of the sediment sample (ST102D) collected from the north stabilization pond revealed detectable cobalt-60 and cesium-137 in addition to naturally occurring nuclides. The activity of the cobalt-60 was 277 pCi/kg dry and the cesium-137 activity was 123 pCi/kg dry.
These results are well within the range of those observed in the past.
5.9.3 Cooling Tower Sediment Disposal Area (Station 119)
Sediments from plant cooling systems containing low levels of radionuclides are disposed of onsite in accordance with EFSEC Resolution No. 299.('") The disposal area for these sediments is located just south of the cooling towers. The REMP monitors the area's direct radiation dose using 2002 REMP ANNUAL REPORT 5-9
quarterly and annual ThDs and by collecting a dry composite sediment sample from the disposal cell within thirty days following each cleaning to confirm that the disposal criteria outlined in the resolution have not been exceeded.
Cleaning of the cooling towers was performed in July 2002. An estimated 20.6 cubic yards of sediment was placed in the disposal area. This material had an estimated density of 1.
grams/cubic centimeter (g/cm3). Using the volume and density, along with the measured activity or the LLD if the nuclide was below detection, it was calculated that the following quantities of nuclides were placed in the disposal area in 2002:
Cobalt-60 LLD: 5.88E+01 pCi/kg 1.02E-06 curies Manganese-54 LLD: 5.89E+01 pCi/kg 1.02E-06 curies Cesium-134 LLD: 4.55E+01 pCi/kg 7.88E-07 curies Cesium-137 Detectable 2.82E-06 curies Of the above nuclides, only the cesium-137 result (163 pCi/kg dry) was above the detection limit.
For the other nuclides the disposal quantity estimates assumed concentrations equal to the respective nuclide.
Measurements of direct radiation were taken using TLDs. The TLDs were collected quarterly and annually. Two locations were used, one next to the collection area (Station 11 9B) and the other approximately 100 yards to the east as the control (Station 119-Control). The mean quarterly TLD result for both Station 1 19B and Station 119-Control was 0.25 mrem/day. The annual TLD results were 0.22 mrem/day for Station 11 9B and 0.23 mrem/day for Station 119-Control.
5.9.4 Spray Pond Drain Field (Station 120)
Sediment from spray pond cleanings had been discharged to a trench located approximately 500 feet south of the spray ponds. In 1995, soil samples taken in the trench indicated detectable amounts of cesium-137 and cobalt-60. In 1996, the deposited sediment was removed to a disposal cell south of the cooling towers. The trench has continued to be the discharge location for spray pond filter backwash water. Soil sampling in the trench is done every two years.
The 2002 sample contained a detectable quantity of cobalt-60 (136 pCi/kg dry). Other nuclides detected were naturally occurring potassium-40, radium-226 and thorium-228.
In 2002, the mean for the quarterly TLD inside the trench was 0.25 mrem/day. The quarterly mean for the control location was also 0.25 mrem/day. The annual result for Station 120 was 0.24 mremlday and Station 119-Control had an annual result of 0.23 mrem/day.
5.9.5 Independent Spent Fuel Storage Installation During 2002, Energy Northwest constructed the Independent Spent Fuel Storage Installation (ISFSI) facility in an area immediately north of Columbia Generating Station. In 1998, the REMP had placed two TLD stations consisting of one annual and one quarterly TLD at the planned site for baseline data. Co-located with the Energy Northwest TLDs are Washington 2002 REMP ANNUAL REPORT 5-10 5-10 2002 REMP ANNUAL REPORT
Department of Health TLDs. Station 121 is located approximately 0.1 mile north of the plant.
Station 122 is on the fence line approximately 0.3 mile north of the plant. During the second quarter of 2002, ten more TLD stations were located on the security fence surrounding the ISFSI.
These stations are Stations 123-129 and Stations 136A-138A. These TLDs are located approximately 0.25 mile north of the plant.
The mean of the quarterly TLDs at Station 121 was 1.08 mremlday while the annual TLD result was 0.99 mrem/day. Station 122 had a mean of 0.27 mrem/day for the quarterly TLDs and an annual result of 0.25 mrem/day. The average of Stations 123-129 and 136A-138A for the quarterly TLDs was 0.36 mrern/day. Station 124 had the highest result with 0.56 mrem/day in the fourth quarter and Station 123 had the low with a result of 0.27 mremlday during the second quarter.
During the fourth quarter, the results from the TLDs hung on the isolation fence showed an average increase of 43.4% over the third quarter due to the presence of the filled casks. The fourth quarter TLDs were hung one week after the first cask was placed in the ISFSI. TLDs on the north part (Stations 123-125) of the fence showed the largest average percentage increase over the third quarter results at 71.5%. On the west side, Stations 126 and 128 showed an average increase of 50.9%. Stations 127 and 129 on the east fence increased over the third quarter by an average of 32.7% and Stations 136A-138A increased by an average of 17.3% over third quarter results. Figure 5-8 shows the quarterly results of each station and the station's position relative to the casks.
5.10 2002 Sample Deviations The majority of deviations for sampling were connected with air sampling. Five deviations were due to unit failures such as blown fuses. The other three were due to power outages to the sampler.
Deviations are listed in Table 5-2.
In November, the new automatic composite sampler located at the SWTF headworks had a plugged sample line. For approximately two weeks, this wastewater stream was not sampled. A grab sample was taken and analyzed and a daily operability check instituted.

6.0 QUALITY ASSURANCE AND QUALITY CONTROL
6.0 QIATITY ASSTJRANCE AND QTAT.TTY CONTROT.
The REMP is designed to meet the quality assurance and quality control criteria of Regulatory Guide 4.15.(4) To accomplish this, the REMP requires that its analytical contractors also meet these criteria. The Energy Northwest Quality group performs in-depth audits of the REMP records and activities and the records and activities of its support organizations at least annually.
Quality assurance and technical audits of the analytical contractor (Teledyne Brown Engineering) are also conducted periodically to verify their compliance to regulatory and contractual requirements. The adequacy of their quality assurance program is assessed during the audits.
Intercomparison programs, which involve the comparison of Energy Northwest analytical results of samples containing known concentrations of various radionuclides, to the known values and also with the results reported by other monitoring programs, are a major component of the quality assurance activities of the REMP. The analytical contractor participates in Environmental Measurements Laboratory (EML) intercomparison program. The REMP also participates in local and regional intercomparison studies. The following sections summarize the quality assurance and quality control aspects of the TLD and analytical components of the REMP.
6.1 Quality Control For the Energy Northwest Environmental TLD Program The Quality Control Program includes the preparation, processing and evaluation of environmental TLDs. All environmental TLDs, including controls, which are to be used in the sarne quarter (or year for annuals), are annealed at the same time. This allows for uniform accumulation of and correction for background radiation. From the time the TLDs are annealed to the time they are placed in the field, they are stored and transported with a set of control TLDs. Once the field TLDs are collected, they are again stored together with the controls until processed.
Reader QC dosimeters are prepared by the TLD processor and serve as indicators that the reader calibration is satisfactory and that the TLDs are processed correctly. These TLDs are annealed just prior to being given a known exposure (typically 100 mR) to cesium-137 and processed among the field dosimeters. The number of QA dosimeters used during each processing is generally 10% of the number of field dosimeters.
If the mean reader QC dosimeter results vary by more than +/- 5% from the given exposure, the processor is contacted and an investigation into the source of the discrepancy is initiated.
Evaluation of the 2002 reader QC dosimeter results indicated satisfactory agreement for all four quarters and the annual processing results.
Control dosimeters (trip controls) are used with each set of field dosimeters to monitor the contribution of the exposure received by the field TLDs while in transit. Radiation background in the storage area is also monitored by a separate set of control dosimeters (building controls). If the trip control results are greater than the building control results, the difference between the two is subtracted from the field dosimeters to account for exposure during transit.
Spiked dosimeters are exposed by Energy Northwest. Quarterly spikes receive a target exposure of 25 nR and annual spikes receive a target exposure of 100 mR. These spiked dosimeters are 6-1 2002 REMP ANNUAL REPORT 6-i 2002 REMP ANNUAL REPORT
processed with the field dosimeters during each run to verify the accuracy and consistency of the environmental TLD evaluations. All results were within +I0% of the known exposure and are provided in Table 6-1.
Extra sets of control dosimeters, known as zero dose dosimeters, are also included with the field dosimeters for processing. These zero dose TLDs are stored in a shielded container throughout the quarter (or year for annuals) and are used as an additional indication of reader performance. These TLDs may also be used as replacements if a field TLD is lost.
6.2 Quality Control For the Analytical Program Quality control for the analytical program involves two components: the quality control activities performed by Energy Northwest and the quality control program of the analytical contractor, Teledyne Brown Engineering. Both of these components are described in the following sections.
6.2.1 Energy Northwest Quality Control Activities Duplicate samples were submitted to Teledyne Brown for analysis during 2002. These duplicates consisted of two sets of milk samples. The milk duplicates were marked Station 37 and were submitted for analysis at the same time as the milk samples from Station 36. Energy Northwest also split samples with the Washington State Department of Health (VDOH) at selected stations.
6.2.2 Teledyne Brown Engineering Quality Control Program The goal of the quality control program at Teledyne Brown Engineering - Environmental Services is to produce analytical results that are accurate, precise and supported by adequate documentation.
The program is based on the requirements of IOCFR50, Appendix B, Regulatory Guide 4.15, and the program described in Teledyne's Quality Assurance Manual (IWL-0032-395) and Quality Control Manual (IWL-0032-365).
All measuring equipment is calibrated for efficiency at least annually using standard reference material traceable to the National Institute of Standards and Technology (NIST). For alpha and beta counting, check sources are prepared and counted each weekday the counter is in use. Control charts are maintained with three-sigma limits specified. Background is usually measured at least once per week.(19)
The gamma spectrometers are calibrated annually with a NIST-traceable standard reference material selected to cover the energy range of the nuclides to be monitored for all of the geometries measured. Backgrounds are determined every other week and check sources are counted weekly.
The energy resolution and efficiency are plotted at two energy levels (59.5 and 1332 KeV) and held within three-sigma control limits.(g The efficiency of the liquid scintillation counters is determined at least annually by counting NIST traceable standards which have been diluted in a known amount of distilled water and various amounts of quenching agent.(20) The background of each counter is measured with each batch of samples. A control chart is maintained for the background and check source measurements as a stability check.
2002 REMP ANNUAL REPORT 6-2 6-2 2002 REMP ANNUAL REPORT
Results are reviewed by the Quality Assurance and/or the Department Manager for reasonableness of the parameters (background, efficiency, decay, etc.) before being entered into the data system.
Any results that are suspect, being higher or lower than results in the past, are returned to the laboratory for recount. If a longer count, decay check, recount on another system or recalculation does not give acceptable results based on experience, a new aliquot is analyzed. Complete information about the sample is contained on the worksheets accompanying the sample results.
The U.S. Environmental Protection Agency (EPA) discontinued its Interlaboratory Comparison Program in December 1998. However, on May 1, 2001, accreditation was granted to Environmental Resource Associates' (ERA) RadCheM Proficiency Testing Program to complete the process of replacing the USEPA-LV Nuclear Radiation Assessment Division Program.
Teledyne participates in the Analytics, Inc., Environmental Resource Associates (ERA),
Department of Energy's Environmental Measurements Laboratory (DOE/EML) and the Mixed Analyte Performance Evaluation Program (MAPEP) intercomparison programs. Teledyne's participation in the programs is for all matrices and radioactive isotopes required for Radiological Environmental Monitoring Program (REMP) clients at the maximum frequency of availability.
Results from these programs are presented in Tables 6-2 through 6-5.
NIST is the approval authority for laboratory providers participating in Intercomparison Study programs.
Tables 6-6 through 6-9 present the Teledyne Brown quality control data results for the in-house water blank and spike program. Samples are spiked with gross alpha, gross beta, tritium, Sr-89 and Sr-90, and I-131.
No deviations from written procedures occurred during 2002. A summary of the quality control blank and spiked sample results follow.
Iodine-131 Cartridges A blank charcoal filter was analyzed with each group of samples assayed. Fifty-two blanks were analyzed in 2002. The blanks were below the detection level.
Gross-Beta - Filters One blank filter was measured with each set of filters assayed. Fifty-two blanks were counted for 2002. The blanks were all below the detection limit, which indicated a relatively stable background for the filter and the gross beta proportional counters.
1-131 - Milk A blank milk sample was analyzed with each group of samples assayed. The results showed that there was no contamination in the laboratory or counting area. The measurements of the blank samples indicated that there was no bias on the low background counters. The average activity for eighteen blank samples in 2002 was 4.24E-02 pCi/liter without considering detection limits.
2002 REMP ANNUAL REPORT 6-3
Sr Milk and Water No blank Sr-90 milks were analyzed during 2002. During 2002, a total of fifty blank water samples were analyzed. The average value for the samples was 8.81E-01 pCi/liter. Fifty spike water samples were analyzed with an average activity of 4.68E+01 pCi/liter of strontium-90.
Gross Beta - Water One hundred fifteen blank samples were prepared from distilled water. The average result without considering detection limits for 2002 was 7.76E-01 pCi/l. One hundred fifteen gross beta spike samples were analyzed during 2002. The average result was 2.61+01 pCi/l. The results were well within the guidelines outlined in, "Environmental Radioactivity Laboratory Intercomparison Studies Program," EPA-600/4-81-004, Table 2.
Tritium in Water Fifty-seven blank samples were analyzed by liquid scintillation counting during 2002. The average result without considering detection limits was 2.20E+00 pCi/liter. Fifty-seven tritium spike samples were analyzed by liquid scintillation counting during 2002. The average result was 6.74E+02 pCi/liter.
Gamma Spectroscopy A blank water sample was analyzed weekly in the gamma spectroscopy laboratory. All nuclides were less than the normal level of detection, indicating no contamination. Spike samples were measured using the Cs-137 peak at 662 KeV. The Cs-137 results were within the 3 sigma limits.
