1 1 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING PEPORT SEQUOYAH NUCLEAR PLANT 1985 Introduction The Sequoyah Nuclear Plant (SQN), operated by the Tennessee Valley Authority, is located on a site owned by TVA containing 525 acres of land in Hamilton County, Tennessee, bounded on the east by Chickamauga Reservoir (see figure 1). The site is 12 miles (19.3 kilometers) northeast of Chattanooga, Tennessee, and 11 miles (17.7 kilometers) west-northwest of Cleveland, Tennessee. The plant consists of two pressurized water reactors; each unit is rated at 3,423 MWt and 1,171 MWe. Fuel was loaded in unit 1 on March 1, 1980, and the unit achieved criticality on July 5, 1980. Fuel was loaded in unit 2 in July 1981, and the unit achieved initial criticality on November 5, 1981. This report describes the environmental radiological monitoring conducted in 1985. The preoperational environmental radiological monitoring program established a baseline of data on the distribution of natural and manmade radioactivity in the environment near the plant site. However, seasonal, yearly, and random variations in the data were observed. In order to determine the potential increases in environ-mental radioactivity levels caused by the plant, comparisons were made between data for indicator stations (those near the plant) and control stations (those remote from the plant) in conjunction with comparisons with preoperational data. Radiological Health (Office of Nuclear Power) and the Office of Natural Resources and Economic Development carried out the sampling program outlined in tables 1 and 23. Sampling locations are shown in figures 2, 3, 4, 5, and 10. Table 2 describes the locations of the atmospheric and terrestrial monitoring stations. All the radiochemical and instrumental analyses were conducted in TVA's Western Area Radio-logical Laboratory (WARL) located at Muscle Shoals, Alabama. Alpha and beta analyses were performed en Beckman Low Beta II and Tennelec LB 5100 low background proportional counters. Nuclear Data (ND) Model 6700 system, in conjunction with germanium detection systems were used to analyze the samples for specific gamma-emitting radionuclides. 131 Specific analysis for I in charcoal filters is performei using NaI(Tl) well detection systems attached to single channel analyzers. TVA-fabricated beta gamma coincidence counting systems are utilized for the determination of 131I concentrations in milk. Tritium determinations are made with Packard Tri-Carb 3255 or 4000 series liquid scintillation counting systems.

2 Data were entered in computer storage for processing specific to the analysis conducted. The data obtained by germanium detectors were resolved by the appropriate analyzer software and the software program HYPERMET. The detection capabilities for environmental sample analysis given as the nominal lower limits of detection (LLD) are listed in table 3. All photopeaks found in germanium spectra were identified and quantified. Many of the isotopes identified by germanium spectral analysis are naturally occurring or naturally p2sRa roduced radioisotopes, such as 7 40 Be, K, 212Bi, 214Bi, 212Pb, 214Pb, , etc. LLDs for additional radionuclides identified by germanium analysis were calculated for each analysi: and nominal values are listed in the appropriate data tables. In the instance where an LLD has not been established, an LLD value of zero was assumed. A notation in a table of " values <LLD" for an isotope with no established LLD does not imply a'Ualue less than 0; rather it indicates that the isotope was not identified in that specific group of samples. For each sample type, only the radionuclides for which values greater than the LLD were reported are listed in the data tables. TVA's WARL participates in the Environmental Radioactivity Laboratory Intercomparison Studies Program conducted by the Environ-mental Protection Agency (EPA)-Las Vegas. This program provides periodic cross-checks on samples of the type and radionuclide composition normally analyzed in an environmental radiological monitoring program. Routine sample handling and analysis procedures were employed in the evaluation of these samples. The results received during calendar year 1985 are shown in table 4. The 130 limits based on one measurement were divided by the square root of 3 to correct for triplicate determinations.

• The Ge(L1) LLD values are calculated by the method developed by Pasternack and Harley as described in NASL-300. These LLO values are expected to vary depending on the activities of the components in the samples. These figures do not represent the LLD values achievable on given samples. Water is counted in either a 0.5-L or 3 5-L Marinelli beaker. Solid samples, such as soll, sediment, and clam shells, are counted in a 0 5-L MarinellI beaker as dry weight. The average dry weight is 400-500 grams. Air filters and very small volume samples are counted in petri dishes centered on the detector endcap. The counting system consists of a ND-6700 multichannel analyzer and germanium detector having an ef ficiency of 20 percent. The counting time is normally 4-15 hours. All spectral analyses are performed using the software program HYPERMET. 2The assumption is made that all samples are analyzed within one week of the collection date.

11 Atmospheric Monitoring The atmospheric monitoring network is divided into three subgroups; local monitors, perimeter monitors, and remote monitors. Four local monitors are located within or near the plant boundary (two of these were installed and one station was relocated during July and August 1985). Perimeter monitors are located at distances out to 10 miles and remote monitors, which are used as control or baseline stations, are located between 11 and 20 miles from the site. There were eight perimeter monitors until July and August 1985, when five were deactivated and the equipment used to establish two local, one perimeter, and two additional remote stations. At present there are four each of local, perimeter, and remote monitoring stations. Each monitoring station consists of an air sampling system, a collection tray and storage container to continuously collect rain-water, a horizontal platform covered with gummed acetate to catch and hold heavy particle fallout, and, at selected stations, a Geiger-Mueller (GM) tube with a recorder to continuously monitor and record gamma radiation levels. Additionally, at two local and one remote monitors 3 moisture is collected from the atmosphere and analyzed for 11. The analysis of gummed acetate paper and rainwater samples was discontinued in July 1985. During 1985, the air particulate and charcoal filter system was modified at all twelve monitoring stations. The modified system uses a 1-7/8-inch diameter glass fiber particulate filter. The charcoal filter used to sample airborne radioiodine is a 2-1/4-inch diameter, 1-inch thick filter filled with TEDA-impregnated charcoal. The partic-ulate and charcoal filter is contained in a round cone-shaped filter holder located on the outside of the monitoring station and protected from rain by a metal overhang housing the gum paper filter. Air is continuously drawn in through the particulate and charcoal filter by an air pump at a flow rate of approximately 2 CFM. The total flow through the system is measured with a domestic type dry gas meter. Each of the local and perimeter air monitors is fitted with a GM tube that continuously monitors the ganna activity levels at the stations. The disintegration rate of the atmospheric radioactivity is continuously recorded at each station. The data from three local monitors (LM 2, LM 3, and LM 5) and f rom three perimeter monitors (PM-2, PM-3, and PM-9) are radiotelemetered into the environmental data station. This system is in the process of being removed. Table 5 presents the maximum permissible concentrations (MPC) specified in 10 CFR 20 for nonoccupational exposure.

l 12 Air Filters Air filters are collected weekly and analyzed for gross beta activity. Adequate time is allowed for decay of radon daughters between collection and analysis. This time period is typically three days. The samples are composited monthly for analysis of specific gamma-emittii.x radionuclides, and quarterly for Sr and 99 89 Sr analysis (strontium analyses were discontinued in June 1985). The results are presented in table 6. During this report period, eight samples were not collected because of equipment problems, eight samples were missed due to equipment relocation, one sample was inadvertently destroyed before analysis, and one sample was unusable due to incorrect recording of sampling time. The annual averages of the gross beta activity in the air particulate filters at the indicator stations (local and petimeter monitors) and at the control stations (remote monitors) for the years 1971-1985 are presented in figure 6. Increased levels due to fallout from atmospheric nuclear weapons testing are evident, especially in 1971, 1977, 1978, and 1981. These fluctuations are consistent with data from radiological monitoring programs conducted by TVA at non-operating nuclear power plant construction sites. Rainwater Rainwater samples were collected monthly from each of the atmospheric monitoring stations. For the first half of the year each sample was analyzed for gross beta activity, specific gamma-emitting isotopes, strontium, and tritium. During the second half of the year rainwater samples were collected monthly but scheduled for analysis only if radioactivity levels in other media indicated the presence of increased levels of fallout. During the period from July to December, no rainwater samples were analyzed. During this report period three samples were not collected due to equipment problems and one sample was not available due to lack of rain. The results from six samples collected in conjunction with the Watts Bar Nuclear Plant (WBN) monitoring program and analyzed for gamma-emitting radionuclides are reported herein. For the gross beta analysis, a maximum of 500 ml of the sample is boiled to dryness and counted. A gamma scan is performed on a 3.5-liter monthly sample The strontium isotopes are separated chemically and counted in a low background system. The results are shown in table 7. Ifeavy Particle Fallout The gummed acetate that is used to collect heavy particle fallout is changed monthly. The collected samples were ashed and counted for gross beta activity. The results are given in table li. In addition, the results from the analysis of seven samples collected in conjunction with the WI1N monitoring program are included herein. During June 1985 fallout collection was deleted from the sampling program.

13 Charcoal Filter Charcoal filters are collected weekly and analyzed for J radioiodine. During this report period, eight samples were not j collected because of equipment problems, eight filters were missed because of equipment relocation, one filter was damaged beyond use, an1 one sample was unusable due to a recording error. Each filter is counted in a single channel analyzer system. The data are shown in table 9. Atmospheric Moisture An atmospheric moisture collection device containing molecular sieve is located at two local monitors and at one remote monitor. Samples are taken every other week, the moisture driven off the molecular sieve, collected in a cold trap, distilled, and counted 3 for H content. The results are shown in table 10. During this reporting period, twelve samples were not collected because of equipment raalfunction, six samples were not taken because of equipment relocation, and three samples were missed because of sample collector error, and nine samples contained insufficient volume for analysis.

25 Terrestrial Monitoring l l Terrestrial monitoring is accomplished by collecting environ-l mental media at locations within the general area of the plant for indicators and at locations remote from the plant for controls, lu I addition to milk, samples include vegetation, soil, ground water, public water and food crops. Environmental gamma radiation levels are determined by strategic placement of thermoluminescent dosimeters. Once each year, a land use survey is conducted to determine census and location of milk producing animals. Land Use Survey The land use survey was conducted during the summer of 1985. Milk animal census and locations were unchanged from the previous survey. Projected doses to individuals in the area were not significantly different from those calculated for 1984. Milk Milk samplec were routinely collected from four indicator locations (twoofwhicharecommericaldairiesjgIandgamma-emitting and from three control I locations. Raw milk was analyzed weekly for radioisotopes and monthly for strontium content. During June 19b5 the sampling frequency was changed to semi-monthly (every two weeks). Iodine-131 and ganza spectral analyses were performed on each sample, with strontium analysis once per quarter. Table 11 summarizes the analytical results. During this reporting period, 8 samples were rat available for collection, and two samples spoiled before analysis. > One of the dairy farms ceased operations in July. DO As has been noted in previous reports, the levels of Sr in milk samples from farms producing milk for private consumption only are up to six times the levels found in milk from commercial dairy farms. Samples of feed and water supplied to the animals were analyzed in 1979 in an effort to determine the source of the strontium. Analysis 90 of dried hay samples indicated levels of Sr slightly higher than those encountered in routine vegetation samples. Analysis of pond water indicated no significant strontium activity. This phenomenon was observed during preoperational radiological monitoring near SQN and Bellefonte Nuclear Plant (BLN) at farms where only one or two cows were being milked for private consumption of the i

26 milk. It is postulated that the feeding practices of these small farmers differ from those of the larger dairy farmers to the extent that fallout from atmospheric nuclear weapons testing may be more concentrated in these instances. Similarly, Hansen, et al., reported an inverse relationship between the levels of '30Sr in milk and the quality of fertilization and land management." Vegetation From January until mid-June vegetation samples were collected quarterly from four farms from which milk samples were collecteil and analyzed for gamma-emitting radionuclides and strontium. Monthly vegetation sampling was conducted at six additional locations and at three control farms. The monthly samples were analyzed for gamma-emitting radionuclides with quarterly analyses for strontium. During this time period one farm went out of business. Starting mid-June the twelve air monitoring stations were added to the vegetation sampling schedule. At this time, the collection frequency for all locations was changed to monthly. These monthly samples were analyzed for 131 1 and for gamma-emitting radionuclides with quarterly analyses for strontium. Approximately 1-2 kg of grass was broken or cut at ground level and returned for analysis. Efforts were made to sample vegetation that was representative of the pasturage where animals graze. Table 12 gives the results obtained from the laboratory analyser. Soil Soil samples were collected annually near each monitoring station to provide an indication of any long-term buildup of radioacti-vity in the environment. An auger or a " cookie cutter" type sampler was used to obtain samples of the top two inches (5 cm) of soil. These samples were analyzed for gamma-emitting radionuclides, and ""Sr and '30Sr. The results are given in table 13. Groundwater An automatic sequential-type sampling device collected groundwater from a well down gradient from SQN. A composite sample from this well was analyzed for gross beta activity alfansen, W.G., Campbell, J.E., Fooks, J.li., Mi tchell, II.C., and Eller, C.H., Farming Practices and Concentrations of Emission Product:. in Milk, U.S. Department of ifcalth, Education, and Welf are; Public Health Service Publication No. 999-R-6, May 1964.

Samples from this well were analyzed monihly during the first half of the year and quarterly thereaf ter, b control well across.the river was also samplid en this srbedule. A quarterly grab sample was also taken from a farm near the plant. The results ot the analysis of well water are shown in tuble 14. During this reporting period, one sample was not collected die to loss of power to the automatic sampling equipment. Public Water Potable water supplies taken from the Tennessee River in the vicinity of SQN were sampled and analyzed monthly for gross beta and gamma-emitting radionuclides. Samples were taken at seven stationr. during the first half of the year and six stations for the remainder of the year. Tritium, 8'3Sr, and 'JOSr concentrations were determined in quarterly composite samples. Th'e first potable water supply downstream from the plant is equipped with att automatic sampler with composite damples analyzed monthly. In addition, the upstream drinking water supply and the upstream surface water station are sampled by automatic samplers. These two stations are considered con +.rols for the downstream pctable water supplies. The results are shown in table 15. During this reporting period, one sample was not cuilected because of equipment malfunction. Figure 7 shaws the trends in gross beta activity in drinking sater Irom 1971 through 1985. The annual-averages reported in 1985 are consistent with the patterns established in the preoperational phase of the monitoring program and are slightly lower than levels reported in surface water samples (figure 11). Environmental Gamma Radiation Levels Bulb-type, Victoreen, manganese-activated, calcium fluoride (Ca2F: Mn), thermoluminescent Josimeters (TLDs) were placed at 16 stations around the plant near the site boundary, at the perimeter and remote air monitors, and at 22 additional stations approximately 5 miles from the site to determine the gamma exposure rates at these locations. The dosimeters, located within energy compensating shields to correct. for energy dependence, are placed approximately one meter above the ground, with three TLDs at each station. They are annealed and read with a Victoreen Model 2810 TLD reader. The values are corrected for gamma response, self-irradiation, and fading, with individual gamraa response calibrations and self-irradiation factors determined for each TLD. The TLDs are exchanged every three months. s;The quarterly gamma radiation levels determined from these TLDs are .;yiven in table 16, which indicates that average levels at onsite stations are approximately 2-4 mP/ quarter higher than levels at offsite stations. This is consistent with levels reported at TVA's nonoperating nuclear power plant construction sites where the average radiation levels onsite are generally 2-6 mR/ quarter higher than levels offaite. The causes of these differences have not been completely isolated; ~ however, it is postulated that the differences are probably attributable ___________________________-.___---_J

28 to combinations of influences, such as natural variations in environ-mental radiation levels, earth moving activities onsite, the mass of concrete employed in the construction of the plant, and other undetermined influences. Figure 8 compares plots of the data from the onsite or site boundary stations with those from the offsite stations during the period 1976 through 1985. To reduce the variations present in the data sets, a four quarter moving average was constructed for each set. Figure 9 presents a trend plot of the direct radiation levels as defined by the moving averages. The data follow the same general trend as the raw data, but the curves are smoothed considerably. Prior to 1976, measurements were made with less sensitive dosimeters, and consequently the levels reported in this phase of the preoperational monitoring program are 1-2 times the levels reported herein. Those data are not included in this report. Food Crops and Poultry Food crops raised in the vicinity of SQN were sampled annually as they became available during the growing season. IJuring this sampling period, samples of cabbage, corn, green beans, potatoes, tomatoes, and apples were collected and analyzed for gross beta and specific gamma-emitting radionuclides. The results are given in tables 17 through 22.

43 Reservoir Monitoring . Samples are collected from the Tennessee River as detailed in table 23. Samples collected for radiological analysis include water and Asiatic clams from three of these cross sections, sediment from four cross sections, and fish from three contiguous reservoirs. The locations of these cross sections are shown on the accompanying map (figure 10) and conform to sediment ranges established and surveyed by TVA. Water Water samples were collected automatically by sequential type sampling devices at three cross sections and composite samples analyzed monthly for gross alpha and beta activity and gamma-emitting radionuclides. Further composites were made quarterly for strontium and tritium analyses. Gross alpha, gross beta, and strontium analyses were discontinued for the SQN surface water samples in June 1985 although some of those analyses were continued for water samples taken in conjunction with both WBN and SQN monitoring programs. Results are displayed in table 24. Figure 11 presents a plot of the gross beta activity in surface water from 1971 through 1985. Indicator stations are those located downstream from the plant and controls are located upstream. The levels reported are consistent with gross beta levels measured in surface water samples taken from the Tennessee River in preoperational monitoring programs conducted by TVA at other sites. During this reporting period, one monthly sample was not collected because of equipment problems. Fish Radiological monitoring for fish was accomplished by analyses of composite samples of adult fish taken semiannually from each of three contiguous reservoirs--Watts Bar, Chickamauga, and Nickajack. No permanent sampling stations have been established within each reservoir; this reflects the movement of fish species within reservoirs as determined by TVA data from the Browns Ferry Nuclear Plant preopera-tional monitoring program. Three species, white crappie, channel catfish, and smallmouth buffalo, are collected representing both commercial and game species. Sufficient fish are collected in each reservoir to yield 250 or 300 gtams oven-dry weight for analytical purposes. Samples collected prior to June 15, 1985, were analyzed for gross alpha, gross beta activity, for gamma-emitting radionuclides, and for strontium content. Samples collected during and after June 15, 1985, were analyzed only for gamma-emitting radionuclides. Results are given in tables 25 through 28. Sediment Sediment samples were collected semiannually from four cross sections of the Tennessee River by dredge hauls made for bottom 1

44 fauna. Samples collected prior to June 15, 1985, were analyzed for gross alpha, gross beta, gamma-emitting radionuclides, and for i strontium content. In June, gross alpha and gross beta measurements in sediment and class were deleted, so that samples collected after Juca 15, 1985, were analyzed only for gamma-emitting radionuclides. Each sample was a composite obtained by combining equal volumes of sediment from each of three dredge hauls at a point in the cross section. Results are given in table 29. One sample was not collected because of equipment damage. In addition to the sampling described above, shoreline sediment samples were collected semiannually at three recreation-use areas (two downstream from the plant and one upstream) in the vicinity of SQN. Samples were taken in May and December. Samples collected in May were analyzed for gross alpha, gross beta, gamma-einitting radionuclides, 893r, and Sr. Samples collected in December were 90 analyzed only for gamma-emitting radionuclides. Results are given in table 30. Asiatic Class Samples of Asiatic clams were collected semiannually with a Ponar dredge from three stations. Those samples collected prior to mid-June were analyzed for gross alpha, gross beta, and gamma-emitting radionuclides. In addition, clam shells were analyzed for strontium content. Samples collected after mid-June were analyzed only for gamma-emitting radionuclides. The analysis of clam shells was deleted from the program in June 1985. Results are given in tables 31 and 32. l

57 Quality Control A quality control program has been established with the Tennessee Department of Public Health Radiological Laboratory and the Eastern Envircnmental Radiation Facility, Environmental Protection Agency, Montgomery, Alabama. Samples of air, water, milk, fish, and soil collected around nuclear plants are forwarded to these laboratories for analysis, and results are exchanged for comparison. ' Data Analysis The results from each sample are compared with the concen-trations from the corresponding control stations and/or appropriate preoperational and background data to determine influences from the plant. During this report period, no activity was identified'which exceeded the reporting levels outlined in Technical Specification 3.12.1. Dose estimates were made from concentrations of radioactivity found in samples of environmental media such as air, milk, drinking water, and fish. Doses estimated for persons at the indicator locations were essentially identical to those determined for persons at control locations. Greater than 95 percent of those doses were contributed by 40 90 137Cs which the naturally occurring radionuclide K, and by Sr, and are long-lived radioisotopes found in fallout from nuclear weapons testing CONCLUSIONS From the above analysis of the data and from the trend plots presented earlier, it is concluded that there were no significant increases in the exposure to members of the general public attributable to the operation of SQN. Indications of the presence of small quantities of fission and activation products have been seen in samples of media such as vegetation, Asiatic clams, and sediment. The levels measured were extremely low, for example near the nominal lower limits of l detection, and were well below the reporting levels required by the Technical Specifications. No increases of radioactivity have been seen in water samples. These media will be monitored closely l for indications of increases. The radioactivity reported herein may be the result of fallout, fluctuations in the existing environment, or computer program artifacts and may include small contributions from SQN or other nuclear facilities upstream from Sequoyah. Any activity resulting from the operation of SQN which may be present is at low levels that are almost impossible to distinguish from background.
