ENVIRONMENTAL RADIOACTIVITYLEVELS BROWNS FERRY NUCLEAR PLANT 1977 Introduction The Browns Ferry Nuclear Plant (BFNP), operated by the Tennessee Valley Authority, is located on a site owned by TVA containing 840 acres of land in Limestone County,

Alabama, bounded on the west and south by Wheeler Reservoir (see figure 1).

The site is 10 miles southwest of Athens,

Alabama, and 10 miles northwest of Decatur, Alabama.

The plant consists of three boiling water reactors; each unit is rated at 3,293 MWt and 1,098 MWe.

Unit 1 achieved criticality on August 17,

1973, and began commercial operation on August 1, 1974.

Unit 2 began commercial operation on March 1, 1975.

However, a fire in the cable trays on March 22, 1975 forced the shutdown of both reac-tors.

Units 1 and 2 resumed operation and Unit 3 began testing in August 1976.

Unit 3 began commercial operation in January 1977.

The preoperational environmental 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 environmental radioactivity levels caused by the plant, compari-sons 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.

Field staffs in the Division of Environmental Planning and the Divi-sion of Forestry, Fisheries, and Wildlife Development carried out the sampling program outlined in tables 1 and 17.

Sampling locations are shown in figures 2, 3, and 4.

All the radiochemical and instrumental analyses were conducted in a central laboratory at Muscle Shoals, Alabama.

Alpha and beta analyses were performed on Beckman Low Beta II and Beckman Wide Beta II low background propoxtional counters.

Two Nuclear Data Model 100 multichannel analyzer systems employing sodium iodide, NaI(T1) detectors and one Nuclear Data Model 4420 in conjunction with Germanium, Ge(Li) detection

systems, were used to analyze the samples for specific gamma-emitting radionuclides.

Samples of water, vegeta-tion, air particulates, food crops, and charcoal (specific analysis for I) 31 are routinely counted with NaI(T1) detection systems.

If significant concen-trations of radioisotopes are identified, or if there is a reasonable expec-tation of increased radioactivity levels (such as during periods of increased

fallout), these samples are counted on the Ge(Li) system.

Identification of gamma-emitting radionuclides in all other types of samples is routinely per-formed by analysis on the Ge{Li) system.

A TVA fabricated beta-gamma coinci-dence counting system is utilized for the determination of I-131 concentrations in milk.

Data were entered in computer storage for processing specific to the analysis conducted.

An IBM 370 Model 165 computer, employing an ALPHA-M least squaxes

code, was used to solve multimatrix problems associated with estimating the activities of the gamma-emitting nuclides analyzed by NaI(T1).

The data obtained by Ge(Li) detectoxs were resolved by the ND-4420 software.

The detection capabilities for environmental sample analysis given as the nominal lower limits of detection (LLD) are listed in table 2.

Samples processed by NaI(T1) gamma spectroscopy wexe analyzed for 13 specific gamma-emitting radionuclides and radionuclide combinations*.

All photopeaks found in Ge(Li) spectra were identified and quantified.

LLD's for the analysis of the radionuclides listed below* are given in table 2-8.

LLD's for additional radionuclides identified by Ge(Li) analysis wexe calculated for each analysis and nominal values are listed in the appropriate data tables.

In the instances where an LLD has not been established, an LLD value of zero was assumed.

Por each sample type, only the radionuclides for which values greater than the LLD were reported are listed in the data tables.

  • The following radionuclides and radionuclide combinations are ~uantified by the ALPHA-M least-squares computer code:

101'144ce; slcr; 31lj Ru'Cs's'r-Nb'o; Mn; Zn'o; " K; and

ATMOSPHERIC MONITORING The atmospheric monitoring network is divided into three groups.

Four local air monitors are located on or adjacent to the plant site in the quadrants of greatest wind frequency.

One additional station is located at the point of maximum predicted off-site concentration of radionuclides (see figure 3).

Four perimeter air monitors are located at distances out to 10 miles from the plant, and two remote air monitors are located at distances out to 45 miles.

These monitoring stations are shown in figure 2.

The remote monitors are used as control or baseline stations.

At each monitor, air is continuously pulled through a Hollingsworth and Voss HV-70 particulate filter at a regulated flow of 3 ft /min. 'In series with, but downstream of, the particulate filter is a charcoal filter used to collect iodine.

Each monitor has a collection tray and storage container to obtain rainwater on a continuous basis and a horizontal platform that is covered with gummed acetate to catch and hold heavy particle fallout.

Thermoluminescent dosimeters are used to record gamma radiation levels at each remote and perimeter station.

Each of the local air monitors is fitted with a GM tube that con-tinuously scans the particulate filter.

The disintegration rate of the atmospheric radioactivity is continuously recorded at each station and radio-telemetered into the plant.

These stations will detect any significant air-borne release from BFNP.

Air filters are collected weekly and analyzed for gross beta activ-ity.

During this reporting period, one sample was not obtained because of adverse weather conditions, one was lost, and two were lost because of equip-ment malfunction.

No analyses are performed until 3 days after sample col-lection.

The samples are composited monthly for analysis of specific gamma-emitting radionuclides and quarterly for Sr, Sr analysis.

The results 89 90 are combined for each station'to obtain a annual average.

These data are presented in table 4.'ith reference to table 3, which contains the maximum permissible concentrations (MPC) recommended by 10 CFR 20 for nonoccupational

exposure, it is seen that the maximum beta concentration is 0.70 percent MPC.

Rainwater is 'collected monthly and a 3.5-liter sample analyzed for specific gamma-emitting radioisotopes.

The results are shown in table 5.

In this sampling period one sample was lost when its container burst, and three were lost because of equipment malfunction.

The gummed acetate that is used to collect heavy particle fallout is changed-monthly.

One sample was lost during this reporting period.

The sample is ashed and counted for gross beta activity.

The results are given in table 6.

Charcoal filters are collected and analyzed for radioiodine.

The filter is counted in a single channel analyzer system.

The data are shown in table 7, where the highest value reported is 0.06 percent MPC for

~I.

Xn this reporting period, one sample was not obtained because of adverse weather conditions, one was accidently destroyed, and two were lost due to equipment malfunction.

  • AllLLD~values for isotopic separations are calculated by the method developed by Pasternack and Harley as described in HASL-300.

Factors such as sample size, decay time, chemical yield, and counting efficiency may vary for a given sample; these variations may change the LLD value for the given sample.

The assumption is made that all samples are analysed within one week of the collection date.

17 Terrestrial Monitorin Milk Milk is collected from at least four farms within a 10-mile radius of the plant (see figure 3), and from four control farms. Raw milk is analyzed weekly for I, and monthly for gamma-emitting isotopes 131 and for radiostrontium. The average results for each farm are shown in table 8. Cow censuses were conducted in May and September 1977. It was determined that there are no dairy farms nearer the plant than the nearest farm being sampled. Ve etation So that any relationship between fallout on pastureland and the presence of radionuclides in milk might be seen, pasturage is sampled quar-terly at the farms from which milk is collected and analyzed for gamma-emitting radionuclides. Table 9 gives the results obtained from the laboratory analyses of these samples. Soil Soil samples are collected annually near each monitoring station to provide an indication of a long-term buildup of radioactivity in the environment. These samples are analyzed for gamma-emitting radionuclides and strontium 89 and 90. The results are given in table 10. Ground Water An automatic sequential-type sampling device has been installed on a well down-gradient from Browns Ferry Nuclear Plant. A composite sam-ple from this well is analyzed for gamma-emitting radionuclides monthly and composited quarterly for determination of tritium. A grab sample is also taken from a control well up-gradient from the plant. During this reporting period, samples were not taken from the control location for four separate sampling periods. The results of the analysis of well ~ater are shown in table 11. Public Water Potable water supplies taken from the Tennessee River in the vicinity of Browns Ferry Nuclear Plant are sampled and analyzed for gross beta and gamma-emitting radionculides, and composited quarterly for tritium analysis. Scheduled strontium analyses were not performed during this reporting period. The first potable water supply downstream from the plant is equipped with an automatic sampler with composite samples collected weekly.

Two additional supplies downstream and one public water supply upstream are collected by monthly grab sampling. Table 12 i'ndicates the results from the analysis of potable water samples. The maximum beta concentration is 0.57 percent HPC. Environmental Gamma Radiation Levels Thermoluminescent dosimeters (TLD's) are placed at nine stations around the plant near the plant boundary and at the perimeter and remote air monitors to determine the gamma exposure rates at these locations. The TLD's are changed every 3 months. The quarterly gamma radiation levels determined from these TLD's are given in table 13. Poultr and Food Cro s Food crops,

grains, and poultry raised in the vicinity of Browns Ferry Nuclear Plant and at control locations are sampled as they become available during the growing season, and analyzed for gamma-emitting radio-nuclides.

During this sampling period samples of tomatoes,

potatoes, green
beans, peaches,
cabbage, soy beans, and poultry were collected and analyzed for specific gamma-emitting radionuclides.

The results are given in tables 14, 15, and 16. Corn was not sampled during this reporting period, and no sample of tomatoes or peaches was taken from a control location.

29 Reservoir Monitorin Samples are collected from the Tennessee River as detailed in table 17. Samples collected for radiological analysis include plankton from three of these cross sections and bottom fauna and sediment from four cross sections. The locations of these cross sections are shown on the accompanying map (figure 4) and conform to sediment ranges established and surveyed by the Data Services

Branch, TVA.

Water Water samples are collected automatically by sequential type sampling devices at three cross sections and composite samples analyzed monthly for gamma-emitting radionuclides. Further composites are made quarterly for strontium and tritium analyses. Sampling locations are shown in table 17. One sample was not obtained when the sampling'quip-ment was damaged by severe weather. Grab samples were also collected monthly from the vicinity of the plant discharge to the Tennessee

River, and at a point on the Elk River.

Results are displayed in table 18. Fish Radiological monitoring for fish is accomplished by analysis of composite samples of adult fish taken from each of three contiguous reser-voirsWilson, Wheeler, and Guntersville. 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 preoperational monitoring program. Two species, white crappie and smallmouth buffalo, are collected representing both commercial and game species. Sufficient fish are collected in each reservoir* to yield 250 to 300 grams oven-dry weight for analytical purposes. All samples are collected semiannually and analyzed for gamma-emitting radionuclides. The composite samples contain approximately the same quantity of flesh from each fish. For each composite a subsample of material is drawn for counting. Results are given in tables 19, 20, and 21. Plankton As indicated in table 17, net plankton (all phytoplankton and zooplankton caught with a 100 p mesh net) is collected for radiological analyses'at each of three stations by vertical tows with a 1/2-meter net. At least 50 grams (wet weight) of material is necessary for analytical

30 accuracy. Samples are collected semiannually and analyzed for gross beta activity, and when quantities are sufficient, for gamma activity and Sr 89 and Sr content. Results are shown in table 22. Sediment Sediment samples are collected from Ponar dredge hauls made for bottom fauna. Gamma radioactivity and Sr and Sr content are determined 89 90 semiannually in composite samples collected from each of four stations. Locations of these stations are shown in table 17. Results are shown in table 23. Bottom Fauna The flesh and shells of Asiatic clams collected semiannually from the cross sections at four stations (table 17) are analyzed for gamma-emitting radionuclides. Levels of Sr and Sr are determined on the

shells, and on the flesh when sufficient amounts were available.

A 50-gram (wet weight) sample provides sufficient activity for counting. Results are given in tables 24 and 25.

41 ualit Control A quality control program has been established with the Alabama Department of Public Health Environmental Health Administration Laboratory and the Eastern Environmental Radiation Facility, Environmental Protection Agency, Montgomery, Alabama. Samples of air, water, milk, and vegetation collected around the BFNP are forwarded to these laboratories for analysis, and results are exchanged for comparison. Data Anal sis Data measured at the control stations for each medium were aver-aged for each sampling period. In order to describe the distribution. of control station data, a mean, standard deviation, and 3-sigma value were calculated. We can expect, with 99 percent confidence, that background concentrations would be distributed within these limits. This provides us the basis for comparing control and indicator data. If the indicator data fall within the limits defined for control data, we can say, with 99 per-cent confidence, that the indicator data were not significantly affected by the nuclear plant. If the data do not fall within the limits, we will perform further analyses to determine if the difference is attributable to the nuclear plant. Conclusions A vast majority of the indicator station data were found to be within the distribution defined by the control station data. The ALPHA-M least squares computer program identified concentrations slightly exceeding the limits of the control station data for a small number of radionuclides in samples from indicator stations. Many of these values may be discounted because the error reported by the ALPHA-M program was greater than the cal-culated concentration. The remaining isolated elevated concentrations may be the result of fallout, computer program artifacts, or analytical errors. The same type of isolated high values occurred in the control station data and may be attributed to the same sources. Increased levels of radioactivity were observed in milk, rain-water, air particulates, heavy particle fallout, vegetation, and in atmos-pheric radioiodine in September and October following the atmospheric nuclear weapons testing conducted by the Peoples'epublic of China. This increase was seen in control stations as well as indicator stations, and was widely reported in the eastern portion of the United States. Levels of I in 131 milk as high as 117.2 pCi/1 were observed. The ~rimary radioisotopes iden-tified in the atmospheric media were Zr, N, I, I, Ba, La, 95 95 31 132 140 140 and Np. It is concluded from the above analysis of the data that there were no significant increases in environmental radioactivity attributable to the operation of Browns Ferry Nuclear Plant.
