ENVIRONMENTAL RADIOACTIVITY LEVELS BELLEFONTE NUCLEAR PLANT ANNUAL REPORT 1981 Introduction The Bellefonte Nuclear Plant (BLN), being constructed by the Tennessee Valley--Authority, is located in Jackson County, Alabama, on a peninsula bounded on the west by Town Creek embayment and on the east by Guntersville Reservoir at Tennessee River Mile (TRM) 391.5 (see figure 1).

The site is approximately 6 miles (10 kilometers) northeast of Scottsboro, Alabama. The plant will consist of two pressurized water reactors; each unit is rated at 3,620 MWt and 1,271 MWe. Fuel load in unit 1 is scheduled for no earlier than 1983.

A preoperational environmental radiological monitoring program was implemented in August 1978. This program has the objective of establishing a baseline of data on the distribution of natural and manmade radioactivity in the environment near the plant site. This report presents the results obtained from that program during 1981.

Staffs in the Radiological Health Staff and the Office of Natural Resources carried out the sampling program outlined in table 1. Sampling locations are shown in figures 2 and 3, and 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 Radiological Laboratory (WARL) located at Muscle Shoals, Alabama, and Eastern Area Radio logical Laboratory (EARL) at Vonore, Tennessee, with WARL being the primary laboratory for processing samples from BLN. Alpha and beta analyses were performed.on Beckman Low Beta II, Beckman Wide Beta II, and Tennelec LB5100 low background proportional counters. Nuclear Data (ND) Model 100 multi channel analyzer systems employing sodium iodide, Nal(T2), 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 an ND Model 6620 system is used with both types of detectors. Samples of water, vegetation, air particulates, food crops, and charcoal (specific analysis for 1311) are routinely counted with NaI(TE) 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.

Identification of gamma-emitting radionuclides in all other types of samples is routinely performed by analysis on the Ge(Li) system. TVA-fabricated and Tennelec beta-gamma coincidence counting systems are utilized for the determi nation of 1311 concentrations in milk. Tritium determinations are made with Beckman LS150, Beckman LS100C, and Packard Model 3250 liquid scintillation counting systems.

2 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 emitting nuclides analyzed by NaI(TQ). 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 lower limits of detection (LLD) are listed in table 3. Samples processed by NaI(Tk) gamma spectroscopy were analyzed for 13 specific gamma emitting radionuclides and radionuclide combinations a. For these analyses, radionuclide combinations such as lo3a106 Ru and gsZr-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 naturally occurring or naturally produced radioisotopes, such as 7 Be, 40 K, 2 12 Bi, Bi, 2 12 Pb, 1 Pb, 2 2 6 Ra, etc. LLDs for the analysis of the radio nuclides listed belowa 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 does not imply a value 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 radioanalytical laboratories participate in the Environmental Radioactivity Laboratory Intercomparison Studies Program conducted by EPA-Las Vegas. This program provides periodic cross-check samples of the type and radionuclide composition normally analyzed in an environmental monitoring program. Routine sample handling and analysis procedures were employed in the evaluation of these samples. The results received during calendar year 1981 are shown in table 4. The +/-3o limits based on one measurement were divided by the square root of 3 to correct for triplicate determinations.

a The following radionuclides and radionuclide combinations are quantified by the ALPHA-M least-squares com uter code: 41

, 44 Ce; 5 1 Cr; 1811. Ru 4 7 Cs; 9 5 13 Cs; '8 Zr-Nb; 58Co; Mn; 6 sZn; soCo; 4 0K; and 14 OBa-La.

11 Atmospheric Monitoring The atmospheric monitoring network is divided into three subgroups.

Two local air monitors are located within the plant boundary. Six perimeter air monitors are located at distances out.to 9 miles (14.5 kilometers) from the plant in the towns of Scottsboro, Hollywood, Fackler, Stevenson, Pisgah, and Section. Two remote.air monitors are located at distances out to 18 miles (29 kilometers) from the plant in the Lim Rock community and the town of Rainsville (see table 2 and figures 2 and 3).

At each monitor, air is continuously pulled through a Hollingsworth and Vose LB5211 glass fiber particulate filter at a regulated flow of 3 ft3 /min (0.085 m3 /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 hori zontal platform covered with gummed acetate to catch and hold heavy particle fallout.

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.

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

During this period seven samples were not collected because of equipment malfunction. No analyses are performed until three days after sample collection The samples are composited monthl for analysis of specific gamma-emitting radionuclides and quarterly for 8 Sr, 9 oSr 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 1978-1981 are presented in figure 4. Increased levels due to fallout from atmospheric nuclear weapons testing are evident in 1981. These fluctuations are consistent with data from monitoring programs conducted by TVA at other nuclear power plant sites.

Table 5 presents the maximum permissible concentrations (MPC) recom mended by 10 CFR 20 for nonoccupational exposure.

Rainwater is collected and analyzed for specific gamma-emitting isotopes. A gamma scan is performed on a 3.5-liter monthly sample. The results are shown in table 7. During this period two samples were not obtained because of equipment malfunction.

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 8.

Charcoal filters are collected weekly and analyzed for radioiodine.

During this period, seven samples were not collected because of equipment malfunction. The filter is counted in a single channel analyzer system. The data are shown in table 9.

21 Terrestrial Monitoring Milk Although there are no commercial dairy farms within five miles of the plant site, milk was collected, when available, from one farm producing milk for private consumption (see table 2), and from one control dairy farm.

Raw milk was analyzed monthly for 13i, gamma-emitting radionuclides, and for radiostrontium. The results are shown in table 10. During this reporting period, one sample was lost during strontium analysis.

As had been noted in earlier monitoring reports, the levels of 9 oSr 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 indicated levels of 9 oSr-slightly higher than those encountered in routine vegetation samples. Analysis of pond water indicated no significant strontium activity.

This phenomenon was also observed during preoperational monitoring at Sequoyah Nuclear Plant in samples taken from a farm where only one to two cows were being milked for private consumption of the 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 9 oSr in milk and the quality of fertil ization and land management.

Vegetation Vegetation samples were collected quarterly from the farms from which milk was collected, and from the vicinity of each.atmospheric monitoring station and analyzed for gamma-emitting radionuclides. Approximately 1-2 kilograms 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 cattle graze. Table 11 gives the results obtained from the laboratory analyses.

Soil Soil samples were collected semiannually near each monitoring station to provide an indication of any long-term buildup of radioactivity in the environment. 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 gamma-emitting radionuclides, 89 Sr, and 9 oSr. The results are given in table 12.

aHansen W.G., et al., Farming Practices and Concentrations of Emission Products in Milk, U.S. Department of Health, Education, and Welfare; Public Health Service Publication No. 999-R-6, May 1964.

22 Ground Water Well water was obtained monthly from two farms in the area and from six onsite wells. All samples were analyzed for gamma-emitting radio nuclides and a quarterly composite was analyzed for tritium. The results are shown in table 13. During this period 14 samples were not collected because the stations were inaccessible.

Public Water Potable water supplies taken from the Tennessee River in the vicinity of BLN are sampled and analyzed for gross beta, gamma-emitting radionuclides, 89 Sr, 9 OSr, and tritium. The results are shown in table 14. Figure 5 shows the trends in gross beta activity in drinking water from 1978 through 1981.

Environmental Gamma Radiation Levels Bulb-type Victoreen Manganese-activated calcium fluoride (CaF 2: Mn) thermoluminescent dosimeters (TLDs) are placed at 15 stations around the plant near the site boundary and at the perimeter and remote air monitors to determine the gamma exposure rates at these locations (see figures 2 and 3). In October 1981 three additional stations were established near the site boundary and TLIs were placed at 18 stations located in the different meteorological sectors around the plant at a distance of approximately 5 miles (figure 6). The dosimeters, in approximate energy compensating shields, are placed at approxi mately one meter above the ground, with two to 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 gamma response calibrations 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 15. It should be noted that even during the preoperational phase of the monitoring program, the average radiation levels onsite are generally 2-5 mR/quarter higher than the levels offsite. This is consistent with levels reported in other preopera tional monitoring programs conducted by TVA 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 7 compares plots of the data from the onsite or site boundary stations with those from the offsite stations over the period from 1978 through 1981. To reduce the variations present in the data sets, a four-quarter moving average was constructed for each set. Figure.8 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.

23 Poultry and Food Crops Food crops and poultry raised in the vicinity of BLN are sampled annually as they become available during the growing season. During this sampling period samples of cabbage, corn, potatoes, tomatoes, turnip greens, and poultry were collected and analyzed for specific gamma-emitting radio nuclides. No sample of corn was taken from a control station. The results are given in tables 16 through 21.

39 Reservoir Monitoring Reservoir sampling at BLN was initiated in November 1981 with the collection of surface water. Surface water samples will be collected quarterly and samples of sediment, Asiatic clams, plankton, and aquatic macrophytes will be collected semiannually beginning in the spring of 1982. Because of the location of BLN between Browns Ferry Nuclear Plant (BFN) and Sequoyah Nuclear Plant (SQN), the reservoirs scheduled to be sampled for fish are already being sampled in the BFN and SQN monitoring programs.

Water Grab samples of surface water are taken quarterly at TRMs 388.0, 391.2, and 396.8 (figure 9) and analyzed for gamma-emitting radionuclides and for tritium. During this reporting period one sample was taken from each station. The results are shown in table 22.

Fish Radiological monitoring for fish is accomplished by analyses of com posite samples of adult fish taken from each of three contiguous reservoirs-the reservoir on which the plant is located and the reservoirs immediately upstream and downstream. No permanent sampling stations are established within each reservoir; this reflects the movement of fish species within reservoirs as determined by TVA data from the Brown Ferry Nuclear Plant preoperational monitoring program. Sufficient fish are collected in each reservoir to yield 250-300 grams oven-dry material for analytical purposes.

The composite samples contain approximately the same quantity of flesh from each fish. For each composite, a subsample of material is drawn for analysis.

Samples of white crappie and smallmouth buffalo are taken semiannually from Guntersville and Wheeler Reservoirs and analyzed for gamma-emitting radionu clides as a part of the BFN monitoring program. In the SQN monitoring program, samples of white crappie and smallmouth buffalo are taken semiannually from Nickajack Reservoir and analyzed for gross beta and gamma-emitting radionuclides.

In addition, 89 Sr and 90 Sr concentrations are determined in one smallmouth buffalo flesh sample and in two whole smallmouth buffalo samples. The data from the analysis of these samples are included herein in tables 23, 24, and 25.

45 Quality Control I

A quality control program has been established with the Alabama Department of Public Health Radiological Laboratory and the Eastern Environmental 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.

Conclusions Since BLN has not achieved criticality, there has been no con tribution of radioactivity to the environment.from the operation of the plant.

The levels of radioactivity being reported in this document are due to natural background radiation, fallout from nuclear weapons testing, or other nuclear operations in the area.
