,ENVIRONMENTAL RADIOACTIVITYLEVELS BROWNS FERRY NUCLEAR PLANT 1976 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.

How-

ever, a fire in the cable trays on March 22, 1975 forced the shutdown of both reactors.

Units 1 and 2 resumed operation and Unit 3 began testing in August 1576.

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, comparisons were made between data for indicator stations (those near the plant) and control stations (those remote from the plant).

Field staffs in the Division of Environmental Planning and the Division of Forestry, Fisheries, and Wildlife Development carried out the sampling program outlined in tables 1 and 16.

The updated Environmental Technical Specifications issued in July 1976 contained a revised environ-mental radiological monitoring program.

This program is indicated by the items enclosed in parentheses in Table 1.

The samples shown in Table 16 were collected quarterly prior to July 1976 and semiannually thereafter.

Sampling locations are sho~n in figures 2>',

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 proportional counters.

Two Nuclear Data Model 2200 multichannel analyzer'systems were used to analyze the samples for specific gamma-emitting radionuclides.

Data were coded and punched on IBM cards or automatically printed on paper tape for computer processing specific to the analysis conducted.

An IBM 370 Model 165 computer, employing an Alpha-M least squares

code, was used to solve multimatrix pro-blems associated with estimating the activities of the gamma-emitting nuclides.

'I f

, It

.A primary difficulty in sample analysis is the detection of very low ra'dionuclide concentrations.

The detection capabilities for environ-mental'ample analysis given as the nominal lower'imits of detection (LLD)~

are 'listed in table 2.

h Samples analyzed by gamma spectral analysis were analyzed for,the 13 specific gamma-emitting radionuclides listed in table 2.

For each sample type, only the radionuclides for which values greater than the 'LLD were

'ep'o'rt'ed are listed in the tables.

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 addi-tional station is located at the point of maximum predicted off-site concentration of radionuclides.

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 con-tinuously pulled through a Hollingsworth and Voss HV-70 particulate filter at a regulated flow of 3 ft /min.

In series with, but down-stream 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 continuously scans the particulate filter. The'isintegration rate of the atmospheric radioactivity is continuously recorded at each'station and radiotelemetered into the plant.

These stations will detect any significant airborne release from BFNP.

Air filters are collected weekly and analyzed for gross beta activity.

No analyses are performed until 3 days after sample collec-tion.

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

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

These data are presented in table 4.

With reference to table 3, which contains the maximum permissible concentrations (MPC) recommended by 10 CFR 20 for nonoc-cupational exposure, it is seen that the maximum beta concentration is 0.51 percent MPC.

Rainwater is collected and analyzed for gross beta activity, specific gamma-emitting isotopes, and radiostrontium.

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 and the strontium isotopes are separated chemically and counted in a low background system.

The results are shown in table 5.

The

, highest value reported for beta activity is 3.8 percent MPC for drinking water.

Gross beta and strontium analyses are not routinely performed under the revised monitoring program but may be done if the gamma scan indicates a need.

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

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 0.09 percent MPC. for I.

  • These measurements are perfomed by gamma spectroscopy.

The LLD values are calculated by the method of Pasternack and Harley as discussed in HASL-300-The original method was published in Nucl. Instr. Methods 91, 533-40 (1971).

These LLD values are expected to vary depending on the activities of components in the samples.

These figures vill be rarely> if ever, attainable.

Water is counted in a 3.5 liter Marinelli beaker.

Vegetation and fish are counted in a 1-pint container as=dry weight.

Meat and poultry are counted in a 1-pint container as-dry veight, then corrected to vet veight using an average moisture content of 70X.

Average dry weight is 250 grams.

Air particulate filters are counted in a veil crystal.

The counting system consists of a multichannel analyzer and either a 4" x 4" solid NaI crystal, or a 4" x 5" NaI veil crystal.

The counting time is 4,000!seconds.

All calculations are perfomed by the least-squares computer program ALpHA-M.

The assumption is made that all samples are analyzed vithin one veek of 'the collection date.

15 Terrestrial Monitorin Mi.lk Milk is collected from five farms within a 10-mile radius of the plant (see fi~ure 3),

and from four control farms.

Raw milk is analyzed weekly for I, and monthly for gamma-emitting isotopes and for radio-strontium The average results for each farm are shown in table 8.

So that any relationship between fallout on pastureland and the presence of radionuclides in milk might be seen',

pasturage is'lso sampled at the farms.

Cow censuses were conducted in June and December 1976. It was determined that there are no dairy farms nearer the plant than the nearest farm being sampled.

Ve e'tation In addition to the pasturage samples mentioned previously, vege-tation samples were collected near each monitoring station in the network to determine possible plant uptake of radioactive materials from the soil or from foliar deposition.

Table 9 gives the results obtained from the laboratory analyses.

In the revised program implemented in July, vegetation is collected at the dairy farms only.

Soil I

Soil samples are collected near each monitoring station in order that any relationship between the amount of radioactive material found in vegetation and that in soil might be established.

The results are given in table '10.

In the revised sampling program soil will be collected annually.

Water Domestic water supplies, obtained from surface streams and wells, narc sampled and analyzed.

Well water is obtained from seven private supplies within a 10-mile radius of the plant.

The results of analyses of well water are shown in table ll and indicate that the maximum beta concentration is 0.30 percent MPC.

Table 12 indicates the results of samples taken, from public water supplies.

The maximum beta concentration is 0.20 percent MPC.

In the revised sampling program a'well downgradient from the plant and the first public water supply downstream from the plant are equipped with automatic water samplers.

Composite samples are analyzed monthly.

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

~\\

II 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 Poultry and food crops raised in the vicinity of Browns Ferry Nuclear Plant and at control locations are sampled as they become avail-able during the growing season.

During this sampling period samples of

tomatoes, potatoes, corn, green beans,
peaches, cabbage, and poultry were collected and analyzed for gross beta, specific gamma-emitting radionu-
clides, Sr, and Sr.

The results are given in tables 14 and 15.

27 Reservoir Monitorin Samples are collected from the Tennessee River as detailed in table 16.

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 January-June 1976 From five of the seven cross sections a total of 15 water samples were collected quarterly for determination of total and dissolved radio-activity.

The locations and depths for sampling are shown in table 16.

Results are displayed in tables 17 and.18.

Samples from all horizontal locations and depths at each river mile cross section were composited quarterly for tritium analy'sis.

Water samples were also collected monthly at the point of plant discharge to.the Tennessee River and at a point on the Elk River.

These samples are a part of the quality control program.

July-December 1976 Water samples are collected automatically by sequential type sampling devices at three cross sections and composite samples analyzed

. monthly.

Sampling locations are shown in table 16.

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 quarterly and analyzed for gamma, gross alpha, gross beta activity, "Sr, and Sr.

The composite samples contain approximately the same quan-tity 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.

In the revised sampling program implemented in July, fish samples are collected semiannually and analyzed for gamma-emitting radionuclides.

28 Plankton As indicated in table 16, 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 !-meter net.

At least 50 grams (wet weight) of material is necessary for analytical accuracy.

Collection of this amount will probably be practical only during the period April to September (spring and summer quarters) because of seasonal variability in plankton abundance.

Results are shown in table 22.

In the revised program, plankton samples are collected semi-annually.

Sediment Sediment samples are collected from Ponar dredge hauls made for bottom fauna.

Gamma and gross beta radioactivity and Sr and Sr content 90 are determined quarterly in composite samples collected from each of four stations.

Locations of these stations are shown in table 16.

Results are shown in table 23.

In the revised program, sediment samples are collected semiannually.

Bottom Fauna The flesh and shells of Asiatic clams collected from the cross sections at four stations (table

16) are analyzed for gamma and gross beta activity at quarterly intervals.

The Sr and Sr contents are deter-mined on the shells, and on the flesh when sufficient amounts were available.

A 50-gram (wet weight) sample provides sufficient activity for counting.

R'esults are given in tables 24 and 25.

In the revised sampling program, benthic samples. are collected semiannually.

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 measured at the control stations for each medium were

~

averaged for each sampling period.

In order to describe the distribution of control station data, a mean, standard deviation, and 3-sigma value were calculated.

Me can expect, with 99 percent confidence, that back-ground concentrations would be distributed within these limits.

This pro-vides us.the basis for comparing. control and indicator data.

If the indi-cator data fall within the limits defined for control data, we can say, with 99 percent 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 attribu-table 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, rainwater, air particulates, heavy particle fallout, vegetation, and in atmospheric radio-iodine in mid-October following the atmospheric nuclear weapons testing con-ducted by the Republic of China.

This incr'ease was seen in control stations as well's indicator stations, and 0as widely reported in the eastern portion of the United States.

Levels of

'I in milk as high as 27.3 pCi/1 were ob:erved.

The primary radioisotopes identified in the atmosphe'ric media were Zr-Nb and Ru.

It is concluded from the above analysis of the data that there were no significant increases in radioactivity attributable to the operation of Browns Ferry Nuclear Plant.
