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 acresof land in Limestone County, Alabama, bounded on the west and south byWheeler Reservoir (see figure 1). The site is 10 miles southwest of Athens,Alabama, and 10 miles northwest of Decatur, Alabama. The plant consists ofthree 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 operationon 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 bothreactors. Units 1 and 2 resumed operation and Unit 3 began testing in August1576. Unit 3 began commercial operation in January 1977.

The preoperational environmental monitoring program establisheda baseline of data on the distribution of natural and manmade radioactivityin the environment near the plant site. However, seasonal, yearly, andrandom variations in the data were observed. In order to determine thepotential increases in environmental radioactivity levels caused by theplant, comparisons were made between data for indicator stations (thosenear the plant) and control stations (those remote from the plant).

Field staffs in the Division of Environmental Planning and theDivision of Forestry, Fisheries, and Wildlife Development carried out thesampling program outlined in tables 1 and 16. The updated EnvironmentalTechnical Specifications issued in July 1976 contained a revised environ-mental radiological monitoring program. This program is indicated by theitems enclosed in parentheses in Table 1. The samples shown in Table 16were collected quarterly prior to July 1976 and semiannually thereafter.Sampling locations are sho~n in figures 2>', and 4. All the radiochemicaland instrumental analyses were conducted in a central laboratory at MuscleShoals, Alabama. Alpha and beta analyses were performed on .Beckman Low BetaII and Beckman Wide Beta II low background proportional counters. TwoNuclear Data Model 2200 multichannel analyzer'systems were used to analyzethe samples for specific gamma-emitting radionuclides. Data were coded andpunched on IBM cards or automatically printed on paper tape for computerprocessing 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 verylow 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„,the13 specific gamma-emitting radionuclides listed in table 2. For each sampletype, only the radionuclides for which values greater than the 'LLD were

'ep'o'rt'edare listed in the tables.4

ATMOSPHERIC MONITORING

The atmospheric monitoring network is divided into threegroups. Four, local air monitors are located on or adjacent to theplant 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 monitorsare located at distances out to 10 miles from the plant, and tworemote air monitors are located at distances out to 45 miles. Thesemonitoring stations are shown in figure 2. The remote monitors areused as control or baseline stations. At each monitor, air is con-tinuously pulled through a Hollingsworth and Voss HV-70 particulatefilter at a regulated flow of 3 ft /min. In series with, but down-stream of, the particulate filter is a charcoal filter used to collectiodine. Each monitor has a collection tray and storage container toobtain rainwater on a continuous basis and a horizontal platform thatis covered with gummed acetate to catch and hold heavy particle fallout.Thermoluminescent dosimeters are used to record gamma radiation levelsat each remote and perimeter station.

Each of the local air monitors is fitted with a GM tubethat continuously scans the particulate filter. The'isintegrationrate of the atmospheric radioactivity is continuously recorded ateach'station and radiotelemetered into the plant. These stationswill detect any significant airborne release from BFNP.

Air filters are collected weekly and analyzed for gross betaactivity. No analyses are performed until 3 days after sample collec-tion. The samples are composited monthly for analysis of specificgamma-emitting radionuclides and quarterly for Sr, Sr analysis.89 90The results are combined for each station to obtain a annualaverage. These data are presented in table 4.

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

Rainwater is collected and analyzed for gross beta activity,specific gamma-emitting isotopes, and radiostrontium. For the gross betaanalysis, a maximum of, 500 ml of the sample is boiled to dryness andcounted. A gamma scan is performed on a 3.5-liter monthly sample andthe strontium isotopes are separated chemically and counted ina low background system. The results are shown in table 5. The

, highest value reported for beta activity is 3.8 percent MPC fordrinking water. Gross beta and strontium analyses are not routinelyperformed under the revised monitoring program but may be done if thegamma scan indicates a need.

The gummed acetate that is used to collect heavy particlefallout is changed monthly. The sample is ashed and counted for grossbeta 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 dataare shown in table 7, where the highest value reported is 0.09 percentMPC. 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 ofcomponents in the samples. These figures vill be rarely> if ever, attainable. Water is counted in a 3.5 liter Marinelli beaker. Vegetation and fishare 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 usingan average moisture content of 70X. Average dry weight is 250 grams. Air particulate filters are counted in a veil crystal. The counting systemconsists 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. Allcalculations 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.

Terrestrial Monitorin

Mi.lk

Milk is collected from five farms within a 10-mile radius of theplant (see fi~ure 3), and from four control farms. Raw milk is analyzedweekly for „ I, and monthly for gamma-emitting isotopes and for radio-strontium The average results for each farm are shown in table 8. Sothat any relationship between fallout on pastureland and the presence ofradionuclides in milk might be seen', pasturage is'lso sampled at the farms.

Cow censuses were conducted in June and December 1976. It wasdetermined that there are no dairy farms nearer the plant than the nearestfarm being sampled.

Ve e'tation

In addition to the pasturage samples mentioned previously, vege-tation samples were collected near each monitoring station in the networkto determine possible plant uptake of radioactive materials from the soilor from foliar deposition. Table 9 gives the results obtained from thelaboratory analyses. In the revised program implemented in July, vegetationis collected at the dairy farms only.

SoilI

Soil samples are collected near each monitoring station in orderthat any relationship between the amount of radioactive material found invegetation and that in soil might be established. The results are given intable '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 supplieswithin a 10-mile radius of the plant. The results of analyses of well waterare shown in table ll and indicate that the maximum beta concentration is 0.30percent MPC. Table 12 indicates the results of samples taken, from publicwater supplies. The maximum beta concentration is 0.20 percent MPC. Inthe revised sampling program a'well downgradient from the plant and the firstpublic water supply downstream from the plant are equipped with automaticwater samplers. Composite samples are analyzed monthly.

Environmental Gamma Radiation Levels

Thermoluminescent dosimeters (TLD's) are placed at nine stationsaround the plant near the plant boundary and at the perimeter and remote

~ \ IIair monitors to determine the gamma exposure rates at these locations. TheTLD's are changed every 3 months. The quarterly gamma radiation levelsdetermined from these TLD's are given in table 13.

Reservoir Monitorin

Samples are collected from the Tennessee River as detailed intable 16. Samples collected for radiological analysis include planktonfrom three of these cross sections-and bottom fauna and sediment from fourcross sections. The locations of these cross sections are shown on theaccompanying map (figure 4) and conform to sediment ranges established andsurveyed by the Data Services Branch, TVA.

Water

January-June 1976

From five of the seven cross sections a total of 15 water sampleswere 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 horizontallocations and depths at each river mile cross section were compositedquarterly for tritium analy'sis. Water samples were also collected monthlyat the point of plant discharge to.the Tennessee River and at a point onthe Elk River. These samples are a part of the quality control program.

July-December 1976

Water samples are collected automatically by sequential typesampling devices at three cross sections and composite samples analyzed

. monthly. Sampling locations are shown in table 16. Results are displayedin table 18.

Fish

Radiological monitoring for fish is accomplished by analysis ofcomposite samples of adult fish taken from each of three contiguous reser-voirs—Wilson, Wheeler, and Guntersville. No permanent sampling stationshave been established within each reservoir; this reflects-the movement offish species within reservoirs as determined by TVA data from the BrownsFerry Nuclear Plant preoperational monitoring program. Two,species, whitecrappie and smallmouth buffalo, are collected representing both commercialand game species. Sufficient fish are collected in each reservoir to yield250 to 300 grams oven-dry weight for analytical purposes. All samples arecollected 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 materialis drawn for counting. Results are given in tables 19, 20, and 21. Inthe revised sampling program implemented in July, fish samples are collectedsemiannually and analyzed for gamma-emitting radionuclides.

28

Plankton

As indicated in table 16, net plankton (all phytoplankton andzooplankton caught with a 100 p mesh net) is collected for radiologicalanalyses at each of three stations by vertical tows with a !-meter net.At least 50 grams (wet weight) of material is necessary for analyticalaccuracy. Collection of this amount will probably be practical onlyduring the period April to September (spring and summer quarters) becauseof seasonal variability in plankton abundance. Results are shown intable 22. In the revised program, plankton samples are collected semi-annually.

Sediment

Sediment samples are collected from Ponar dredge hauls made forbottom fauna. Gamma and gross beta radioactivity and Sr and Sr content90are determined quarterly in composite samples collected from each of fourstations. Locations of these stations are shown in table 16. Results areshown in table 23. In the revised program, sediment samples are collectedsemiannually.

Bottom Fauna

The flesh and shells of Asiatic clams collected from the crosssections at four stations (table 16) are analyzed for gamma and gross betaactivity 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 AlabamaDepartment of Public Health Environmental Health Administration Laboratoryand the Eastern Environmental Radiation Facility, Environmental ProtectionAgency, Montgomery, Alabama. Samples of air, water, milk, and vegetationcollected 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 valuewere 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 significantlyaffected 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 bewithin the distribution defined by the control station;data. The Alpha-Mleast squares computer program identified concentrations slightly exceedingthe limits of the control station data for a small number-of radionuclidesin samples from indicator stations. Many of these values may be discountedbecause the error reported by the Alpha-M program was greater than the cal-culated concentration. The remaining isolated elevated concentrations maybe the result of fallout, computer program artifacts, or analytical errors.The same type of isolated high values occurred in the control station dataand 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 stationsas well's indicator stations, and 0as widely reported in the eastern portionof the United States. Levels of 'I in milk as high as 27.3 pCi/1 wereob:erved. The primary radioisotopes identified in the atmosphe'ric mediawere Zr-Nb and '' Ru.

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