ENVIRONMENTAL RADI0 ACTIVITY LEVELS SEQUOYAH NUCLEAR PLANT ANNUAL REPORT ,

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 achiev'ed 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 1982.
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 I
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 i with preoperational data.
4 The Radiological Health Staff (Office of Power)' and the Office of Natural Resources carried out the sampling program outlined in tables 1 and 27.
Sampling locations are shown in figures 2, 3, 4, and 10, and table 2 describes
- the locations of the atmospheric and terrestrial monitoring stations. All the i
radiochemical and instrumental analyses were conducted in TVA's Western Area
) Radiological Laboratory (WARL) located at Muscle Shoals, Alabama, and Eastern 3 Area Radiological Laboratory (EARL) at Vonore, Tennessee,'with the EARL being the primary laboratory for samples from SQN. Alpha and beta analyses were per-
, formed _on Beckman Low Beta II, Beckman Wide Beta-II, and Tennelec LB 5100 low background proportional counters. ' Nuclear Data (ND) Model 100 multichannel analyzer systems employing sodium iodide, NaI(TI) detectors and ND Model 4420 Systems in conjuction with Germanium, Ge(Li) detection systems were used to analyze the samples for specific gamma-emitting radionuclides. At EARL, a ND Model 6620 system is used with both types of detectors. Samples of water, vegetation,airparticulates,'foodcrops,andcharcoal(specificanalysisfor M
I) are routinely counted with NaI(TI) detection systems. 'If significant concentrations of radioisotopes are identified, or if there is a reasonable expectation-of increased radioactivity-levels (such~as during periods of increased fallout), these samples are counted on the Ge(Li) system.. Identi-fication of gamma-emitting radionuclides in all other types-of samples is routinely performed by analysis on the Ge(L1) system. TVA-fabricated and

, counting systems.
Data were; entered in computer storage for processing specific to the analysis conducted. A computer, employing an ALPHA-M least-squares code, ,
using multimatrix. techniques was used to estimate the activities of the. gamma- i emitting nuclides_ analyzed by NaI(T1). The data obtained by Ge(Li) detectors were resolved by the appropriate analyzer software and the metric minimization routine HYPERMET.
The detection capabilities for environmental sample analysis given as the nominal <1ower limits of detection (LLD) are listed in table 3. Samples 4
processed by NaI(TI) gamma spectroscopy were analyzed for 14 specific gamma-emitting radionuclides and radionuclide combinations . For these analyses, radionuclide combinations such as tos,10sRu and 85 Zr-Nb are analyzed as one radionuclide. All photopeaks found in Ge(Li) spectra were identified and quantified. Many of the isotopes. identified by Ge(Li) spectral analysis are 7
naturally 4 occurring or naturally produced radioisotopes, such as Be, 40K, 212Bi, 2 Bi, 212Pb, 214Pb, 22sRa, etc. LLDs for the analysis of the radio-nuclides listed below" are given in table 3B. LLDs for additional radio-nuclides identified by Ge(Li) analysis were calculated for each analysis 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 .
7 does not imply a value less than 0; rather it indicates that the isotope was 4
not identified in that specific group of samples. For each sample type, only l
the radionuclides for which values greater than the LLD were reported are listed in the data tables.
1 TVA's Radioanalytical Laboratories participate in the Environmental I Radioactivity Laboratory Intercomparison Studies Program conducted by EPA-Las I Vegas. This program provides periodic cross-check samples of the type and l
radionuclide composition normally analyzed in.an environmental monitoring i i
p rogram. Routine sample handling and analysis procedures were employed in the evaluation of these samples. The results received during calendar year 1982 are shown in table 4. The 13a limits based on one measurement were divided by the square root of 3 to correct for triplicate determinations.
- The following radionuclides and radionuclide combinations are quantified by the ALPHA-M least-squares coquter code: 141'144Ce: s1Cr; 131I. 10s,10sRu; ,
, 134Cs; 137Cs; ssZr-Nb; ssCo; 4 Mn; ssZn; s9pe; 60co; 40K; and 1 oBa-La. l D

Atmospheric Monitoring The atmospheric monitoring network is divided into three subgroups.
Two -local air monitors are located within the plant boundary. Eight perimeter air monitors are located at distances out to 10.5 miles (16.9 kilometers) from the plant in the towns of Sale Creek, Daisy, Red Bank (Northwoods), Harrison, and four other populated areas. The remote air monitors used as control or baseline stations are located at distances out to 17.75 miles (28.6 kilometers)
I, from the plant in the town of Dayton and the city of Chattanooga. See figures
- 2, 3, 4, a'nd 5.
At each monitor, air is continuously pulled through a Hollingsworth and Voss LB 5211 glass fiber filter at a flow of 3 fta/ min (0.085 m 3/ 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 collect rainwater on a continuous basis, and a horizontal platform covered with
- gummed acetate to catch and hold heavy particle fallout. Moisture is collected from the atmosphere at each local monitor and at one remote monitor and analyzed for tritium.
Each of the local and perimeter air monitors is _ fitted with a GM tube that continuously scans the particulate filter. The disintegration rate of the atmospheric radioactivity is continuously recorded at each station.
The data from the two local monitors and the four perimeter monitors located within approximately five miles of the plant are radiotelemetered into the plant control room.
Air filters are collected weekly and analyzed for gross beta activity.
During this reporting period ten samples were not obtained because of equipment malfunction. No analyses are performed until three days after sample collection.
The samples are composited monthly for analysis of specific gamma-emitting radio-nuclides and quarterly for 89Sr and 90 Sr analysis. Five samples were lost during the strontium analysis. The results are presented in table 6.
The annual averages of the gross beta activity in the air particulate
, filters at the indicator stations (local and perimeter monitors) and at the control stations (remote monitors) for the years 1971-1982 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 fluctua- 1 i tions are consistent with data from monitoring programs conducted by TVA~~at l nonoperating nuclear power plant construction sites.
Table 5 presents the maximum permissible concentrations-(MPC) specified in 10 CFR 20 for nonoccupational exposure.
Rainu ter is collected and analyzed for-gross beta activity, specific gamma-emitting isotopes, and strontium. During tihis period one sample was not available for any analyses, and four samples were lost or destroyed during strontium analyses. 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.

1 The summed acetate that is used to collect heavy particle fall'6ut is
~
changed monthly. The samples are ashed and counted for gross beta activity.
- The results are given in table 8. During this reporting period one sample.was lost during analysis.
Charcoal filters are collected and analyzed for-radioiodine. During this period nine samples were not obtained because of equipment malfunction.
The filter is counted in a single cha'anel analyzer : system. The data are shown '
- initable 9.

An atmospheric moisture collection device containing molecular
- sieve is . located at each local monitor 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 -for tritium content. The results are shown in. table 10.

Raw milk is analyzed weekly for tai l, and monthly for gamma-emitting isotopes, and for strontium. The results are shown in L -table 11.- Four samples were lost or destroyed during this reporting period.
. As has been noted in the other monitoring reports, the levels of 80 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 of dried hay samples i
- indicated levels of 80 Sr slightly higher than those encountered in routine vegetation samples. Analysis of pond water indicated no significant strontium j activity. _
l I
This phenomenon was observed during preoperation monitoring near
~
Sequoyah and Bellefonte Nuclear Plants at farms where only one or two cows were being milked for private consumption of the milk. It is postulated that '
j the -feeding practices of these small farmers differ from those of the larger -
i dairy farmers to the extent that fallout from atmospheric nuclear weapons
- testing may be more concentrated in these instances. Similarly,'Hansen, et l
! al., reported an inverse relationship between the levels of 80Sr in milk and I
the quality of fertilization and land management."
) Land Use Survey i
} The routine land use survey was conducted in the summer of 1982. It f was determined that there are no milk animals nearer the plant than those in ~
[ areas from which either milk or vegetation is being sampled. .It was concluded from evaluations of the survey results that the small changes in land use have not increased the projected doses to individuals in the area and that appropriate '
i sampling is.being conducted.
j .
Vegetation ,
Vegetation samples are collected quarterly from four. farms from which~ '
i milk is collected and analyzed.for gamma-emitting radionuclides. Monthly vege-
. tation sampling is conducted at three additional locations and at three control ,
t farms.- - 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 repre i
sentative of the pasturage where cattle graze. In addition to the gamma spectral

b 26 analysis, 40 samples were analyzed for 89 Sr and 90 Sr content. Table 12 gives
, the results obtained from the laboratory analyses.
Soil Soil samples were collected annually.near each monitoring station to provide an indication of any long-term buildup of radioactivity in,the environ-
, ment. Two additional samples were taken at one of the control stations in ccnjunction with the Watts Bar Nuclear Plant monitoring program. An auger or
" cookie cutter" type _ sampler was used to obtain samples of the top two-inches (5 cm)' of soil. These_ samples were analyzed for gross beta activity,-gamma- i emitting radionuclides, s9Sr, and 80 Sr. .The results are given in table 13.

Ground Water '
An automatic sequential-type sampling device has been installed on a l i well downgradient from Sequoyah Nuclear Plant. A composite sample from this l
- wall is analyzed for gross beta activity.and gamma-emitting radionuclides ,
monthly and composited quarterly for determination of tritium. A grab sample i is also taken from a farm near the giant and a control well'across the river '
from the plant. The results of the analysis of well water.are shown in table 14.
t j
j Public Water
, Potable water supplies taken from the Tennessee River in the vicinity i of Sequoyah Nuclear Plant are sampled and analyzed monthly for gross beta and grama-emitting radionuclides. Tritium, 89Sr,'and 90Sr concentrations are i
determined in quarterly composite samples. EThe first potablet water. supply downstream from the plant is equipped with.an automatic sampler with composite samples analyzed monthly. One strontium sample was lost during processing..iThe results are shown in table 15.
Figure 7 shows the trends in gross beta activity in drinking. water. !
from 1971 through 1982. The annual averages reported,in 1982 are consistent- l 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).
t Environmental Gamma Radiation Levels Bulb-type Victoreen manganese-activated calcium fluoride-(Ca2FDNn) thermoluminescent dosimeters (TLDs) are 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'gasma exposure rates at- these locations. The dosimeters, in energy compensating 4

27 shields to correct energy dependence, are placed at 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 l response, self-irradiation, and fading, with individual gamma response calibra-tions and self-irradiation factors determined for each TLD. The TLDs are exchanged every three months. The quarterly gamma radiation levels determined from these TLDs are given in table 16, which indicates that average levels at onsite stations are approximately 2-3 mR/ 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 offsite. The causes of these differences have not been completely isolated; however, it is postulated that the differences are probably attributable to combinations of influences, such as natural variations in environmental 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 over the period from 1976 through 1982. 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 i 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, i Prior to 1976 measurements were made with less sensitive dosimeters, '
and consequently the levels reported in this phase of the preoperational moni-toring program are 1-2 times the levels reported herein. Those data are not included in this report.
j Poultry and Food Crops Food crops, poultry, and beef raised in the vicinity of SQN are i
sampled annually as they.become available during the growing season. During 1 this sampling period, samples of apples, cabbage, corn, green beans, lettuce, potatoes, tomatoes, and turnip greens were collected and analyzed for gross j beta and specific gamma-emitting radionuclides. Poultry and beef samples were collected and analyzed for gamma-emitting radionuclides. The results are given in tables 17 through 26.

4 47 Reservoir Monitoring Samples are collected from the Tennessee River as detailed in table 27. -
j' 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 y are shown on the accompanying map (figure 10) and conform to sediment ranges .
established and surveyed by TVA.
d Water Water samples are collected automatically by sequential type sampling 4 devices at three cross sections and composite samples analyzed monthly for gross alpha and beta activity and gamma-emitting radionuclides. Further com-posites are made quarterly for strontium and tritium analyses. Results are
- displayed in table 28. Figure 11 presents a plot of the gross beta activity In surface water from 1971 through 1982. 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.
1 Fish
- Radiological monitoring for fish was accomplished by analyses .of l
' composite samples of adult fish taken semiannually from each'of three contigu-ous 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 preoperational monitoring program. Three species, white i
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 200 grams oven-dry weight for analytical purposes.
All samples were analyzed for gamma, gross alpha,-and gross beta activity. In j- addition, two samples of each species were analyzed for 89Sr, and 90 Sr. The
- composite samples contained.approximately the same quantity.of flesh from each fish. For each composite a subsample of material was drawn for counting.
Results are given in tables 29 through'32.
Sediment ,
Sediment samples were collected semiannually from dredge hauls made for 80 bottom fauna. Gamma,; gross, alpha, and gross beta. activity'and.s9Sr and '
~
Sr content were determined in samples collected ~from points in four cross ,
sections. Each sample was a composite obtained by combining equal volumes of j sediment from each of three' dredge hauls at a point in the. cross section.-
Results are given in table 33.

C> Data measured at the control stations for each medium were averaged for each sampling period. In order to describe the distribution of control i]<
.H station data, a mean, standard deviation, and 3-sigma limits were calculated.
m; We car. expect that background concentrations would be distributed within these ' ' . ;j 1 limits. This provides the basis for comparing control and indicator data. If .
',l [
the indicator data fall within the 3-sigma limits defined for control data, we .f.i ;
conclude that the indicator data were not significantly affected by the nuclear : ~
