1. 0 INTRODUCTION This report summarizes the Environmental Radiological Monitoring Program conducted for the Arkansas Nuclear One - Units 1 and 2 during the calendar year 1985. All samples analyses and data interpretation were performed by the staff of Arkansas Power and Light Company.

1.1 PLANT AND LOCATION Arkansas Nuclear One - Units 1 and 2 are both light water cooled pressurized water raattors located approximately 5.0 miles west of Russellville, Arkansas. ANO Unit 1 began commercial operation in

! December 1974 and the second unit at the same site, ANO Unit 2, i

l followed in March 1980. Lake Dardanelle is the source of the circulating cooling water for ANO Unit 1, and ANO Unit 2 is cooled by a

] cooling tower, also dependent upon Lake Dardanelle water.

1.2 ENVIRONMENTAL MONITORING PROGRAM l

i The Environmental Monitoring Program was established based upon the Environmental Technical Specifications for ANO Unit 1, section 4.3 and 1 Unit 2, section 3/4 12. These sections became effective January 1, 1985. Some of the program requirements changed were a reduction in fish sampling sites, deletion of precipitation sampling, increase in the number of TLD locations, addition of an annual land use survey and required participation in an analytical cross check program. Many of the aspects of the program, which are no longer required, were i

continued in 1985 and all data is included in this report. Table 1.2.1 details the surveillance program listing sample type, frequency of collection, and the method of analysis used. Table 1.2.2 lists'the sample location and type of samples collected at each location. TLD locations are given in Table 1.2.3. Figure 1.2.1 gives the aquatic '

biota (fish) sampling areas. Figures 1.2.2 and 1.2.3 depict the i location of the plant site.

! 2.0 INTERPRETATIONS AND CONCLUSIONS Data collected from radiological analyses, of environmental samples collected in the area surrounding the ANO facility, indicates no dose to the general public in excess of design objectives as a result of liquid and gaseous discharges from the ANO site during 1985. Also, no non-routine environmental radiological monitoring reports resulting from analyses of environmental samples were submitted to the U.S. NRC during 1985. Reporting levels are given in Table 2.0.1.

2.1 SAMPLES ASSOCIATED WITH AIR MONITORING j

Also, none of the 84 monthly composites of air particulate filters analyzed in the calendar year 1985, including the control air

( particulatesamplesfromDanville, Arkansas $ndicatedthe-presenceof l

radioactive fission or activation products.

i

. None of the 312 samples collected from indicator locations for radioiodine in air (using activated charcoal filters) indicated

] iodine-131 activities greater than the lower limit of detection, which is 0.070 pCi per cubic meter of air.

1 l TLD data collected for the calendar year 1985 is divided into two l

I categories. The first category includes the lithium fluoride (LiF)

TLDs which were collected and read quarterly, and the second category includes (LiF) TLDs which were collected and read semiannually. The quarterly TLD data for 1985 indicated a total yearly average dose for the forty-three indicator locations to be 61 mrem per year compared to j the total yearly average dose of 68 mrem for 1984. The control i s location at Danville, Arkansas (209* - 19.3 miles) indicated a total dose, based upon quarterly TLDs, of 57 mrem per year for 1985 compared

to 67 mrem for 1984. Table 2.1.1 lists the total yearly average dose j for the indicator location for the calendar years of 1980, 1981, 1982, j

1983, 1984 and 1985 compared to the total dose of background radiation

! (control station).

l 4

s

The difference between the indicator locations and the control location for 1985 quarterly TLDs results is not statistically significant. The standard deviation for the indicator locations is 5.8 mrem annual dose.

For a one sample t-test, (i.e. , a single control compared to all indicator locations), a t-value of 0.84 is obtained. This t value does not indicate a significant difference between the control and indicator locations at the 95% confidence level. A t-value of greater than 1.96 would be necessary to indicate a significant difference.

Factors other than statistical fluctuations that may affect the varietion in recorded dose include variations of up to 15% in response of the TLD chips to the same radiation exposure, different soil types at monitoring locations, and varying heights above ground level for TLD placement.

The TLDs collected every six months during 1985 indicated slightly lower readings than the quarterly TLDs, which is consistent with TLD readings recorded in previous years. The lower dose measurement for the dosimeters deployed in the field for six months co'npared to the quarterly readings is attributed to " fading" of the lithium fluoride chips. The TLDs collected every six months indicated a total yearly average dose for the indicator locations of SG mrem, compared to 56 mrem in 1984. The six-month TL0s are located at six indicator locations and one control location. The control location indicated a total dose, based upon TL0s collected and read semiannually, of 55 mrem, compared to 61 mrem in 1984.

I'.)

The small difference in six month 1985 TLD data between indicator locations and control location is not significant. The standard deviation for the indicator locations is 2.64 mrem annual dose. A t-value of 0.66 is calculated for a single sample t-test comparing the indicator locations to the control. At the 95% confidence level at t-value of greater than 2.20 would be necessary to indicate any statistically significant difference.

None of the 109 rain samples collected and analyzed in 1985 indicated the presence of radioactive fission or activation products. Analyses performed were gamma spectrometry and gross beta.

2.2 SAMPLES ASSOCIATED WITH WATER MONITORING Lake water samples are collected from five different sample sites in Lake Dardanelle monthly, plus the Arkansas Department of Health and Arkansas Power and Light Company split a surface water sample from the ANO Discharge Canal and Piney Bay monthly. Each laboratory analyzes the sample for gamma emittering isotopes. No surface water samples with measurable quantities of plant related gamma emitting radioisotopes were collected during 1985. Tritium was detected in approximatley one half of the Discharge Canal samples, but the maximum concentration observed was only 4% of the reporting level for drinking water sources. Sr-89 and 90 were observed in comparable concentrations at indicator and control locations.

p

r As in previous years, bottom sediments collected from the ANO Discharge

, Canal (0.1 mile 180 ) during 1985 radioisotopes attributable to ANO

, operations. To determine the maximum whole body dose exposure from sediments, dose calculations were performed according to the i

mathematical model for determining external dose from sediment given by l U.S. Nuclear Regulatory Commission Regulatory Guide 1.109. Tables 2.2.1 and Table 2.2.2 give the results of these calculations for samples collected from the ANO Discharge Canal in March and September 1985. The maximum external dose to the skin from sediments for all measurable radionuclides was approximately 0.20 mrem per year and the i maximum whole body dose was approximately 0.17 mrem per year from the

March 1985 sample.

1 i

According to AN0 Technical Specifications, the design objectives for the dose to the whole body or any organ of an individual is 5 mrem per year as the result of release of liquid wastes. The values of 0.17 mrem per year for maximum whole body dose and 0.20 mrem per year for

! maximum external dose to skin of a teenager is well within the design

objective criteria.

1 1

No reactor produced gamma emitting isotopes were detected in ground

] water samples collected during 1985. One tritium analysis of ground 1

water produced a positive result, however, the two sigma counting error represented 93% of the tritium concentration.

1 i

No reactor produced gamma emitting isotopes were detested in drinking l water samples collected during 1985. Strontium 89 and 90 i

concentrations in the drinking water were comparable to the control ij

location. Positive Iodine 131 results were obtained in approximately on half the samples, however, the maximum I-131 concentration was less than the required Lower Limit of Detection. Positive results in these concentrations contain a high percentage of counting error.

The 1985 fish samples collected include the two categories: 1) catfish sample, and 2) bass and crappie samples. Edible portions of these fish samples are analyzed by gamma spectrometry for radioisotopes. The highest level of reactor produced radioisotopes attributed to operations at ANO were found in bass and crappie fish collected September 3, 1985 from the ANO Discharge Canal (0.1 mile 180 ).

Dose calculations based upon the bass and crappie fish radioisotope concentrations were found according to the mathematical model for determining maximum total dose to total body from fish consumption given by the U.S. NRC Regulatory Guide 1.109. Tables 2.2.7 and 2.2.8 identify the radioisotopes found in the bass"and crappie fish, the amount of radioactivity present, and the contribution of the total maximum calculated dose for either whole body or specific body organs.

According to these calculations, the maximum dose to adults to total body from bass and crappie fish consumption is about 0.5 mrem per year to the liver. The value of 0.5 mrem per year is well within the design objective criteria of 5 mrem per unit as defined in the AN0 Technical Specifications for liquid wastes. Tables 2.2.3 through 2.2.8 identifies all radioisotopes found in six fish samples collected and analyzed in 1985.

i.,

e...

In addition to the fish samples described above, edible portions of fish were collected by the Arkansas Department of Health, on May 10 and October 10, 1985. In Table 2.2.3 and 2.2.4, dose calculations were performed according to the mathematical model given by U.S. NRC

Regulatory Guide 1.109. The highest calculated dose to adults from

Concentration of Cs-134 and Cs-137 in edible portions of fish have stabilized over the past three years.

2.3 SAMPLES ASSOCIATED WITH TERRESTRIAL MONITORING Milk samples were collected by with split with the Arkansas Department of Health in all twelve months of 1985. The milk sampling program consisted of three indicator locations for and one control location, the R. A. Young Diary (12.0 miles 73*), during 1985.

Monthly milk samples are analyzed for Iodine-131 by concentrating the iodine with anion exchange resin and counting the concentrated iodine sample in a low-background alpha / beta counting system. Control and indicator locations Iodine I-31 concentrations. All positive I-131 results were below the required Lower Level of Detection.

No gamma emitting radionuclides were detected by gamma spectrometry in milk samples collected in 1985, including the R. A. Young Dairy, the control dairy.

Strontium-89 and Strontium-90 analyses in milk identified average strontium activities at indicator locations similar to the results for the control location.

Vegetation samples were divided into two categories in 1985, pasturage vegetation and garden products vegetation. Of the 38 pasturage samples collected and analyzed in 1985, Cesium-137 was the only gamma emitting i

l' radionuclide determined in pasturage samples. Cesium-137 was detected f in three samples from indicator locations and in no control samples from Danville, AR. Twenty-five garden products vegetation samples were j collected in 1985 from four gardens. Garden vegetation collected and

! analyzed included cabbage, head lettuce, tomatoes, potatoes, l

cantaloupes, cucumbers, peppers, greens, turnips,'and leaf lettuce. No

! gamma emitting radionuclides were detected in any garden products

vegetation during 1985, i Soil samples were collected in May and November 1985 from seven ,

sampling stations each time. Cesium-137 was detected in all 14 soil j samples. Due to its wide spread presence international fallout is the ,

l probable source of this fission produced radionuclide.

Environmental Radioactivity Laboratory Intercomparison Studies Program.

The major objective of this program is to assist laboratories involved in environmental radiation measurements to develop and maintain both an intra-laboratory and an inter-laboratory quality control program. This is partially accomplished through a laboratory intercomparison studies program involving environmental media (milk, water and air) and a variety of radionuclides with activities at or near environmental levels.

During the calendar year 1985, the following sample types were received and analyzed:

1) Gross Alpha-Beta in Water - A one-liter sample for the analysis of gross alpha and gross beta activity.

2) Gamma in Water - A one-liter sample containing chromium-51, 4

zinc-65, cobalt-60, ruthenium-106, cos tum-134 and cesium-137.

3) Tritium in Water - A twenty-five mi sample containing tritium.

en \

4) Iodine-131 in Water - four-liter sample containing iodine-131.

5) Strontium in Water - A one-liter sample containing strontium-89 and strontium-90.

6) EPA Blind in Water - A one-liter blind sample containing a mixture of radionuclides.

7) Milk - Four-liter milk sample containing potassium, strontium-89, strontium-90, iodine-131, and cesium-137.

8) Air - A two-inch diameter air filter is distributed quarterly for gross alpha, gross beta, cesium-137 and strontium-90 analyses.

9) Low-Level Water - A four-liter sample containing very low quantities of I-131.

10) Low-Level Milk - A four-liter sample containing very low quantities of I-131.

A report listing the results of the analysis containing the laboratory standard deviation, calculation of the normalized range, normalized deviation, sample standard deviation, and the grand average of all laboratories is mailed after each participating laboratory performs three independent determinations for each radionuclide involved in the study.

.. l I

Table 2.5.1 lists the various analyses that are performed, the radioactivity levels found in the EPA cross-check samples, and one standard deviation for a single determination.

If the Technical Analysis Section Environmental Laboratory results differ by more than 3 standard deviations from the known results given in the EPA cross-check reports, the instrument and procedure are checked for error.

Table 2.5.2 lists the date of preparation, types of EPA cross-check samples received, the total number of analyses performed, the average sample standard deviation based upon three independent determinations for each radionuclide in each sample, and tho' number of standard deviations the AP&L lab differed from the~known value.

Most of the results were well within three standard deviations of the known values supplied by the U.S. EPA.

Gross beta results in EPA air filters differed from the known values by approximately 3 standard deviations in the March 29 and August 30, 1985, samples. The mixture of isotopes in the EPA sample produces a different beta energy mix compared to the calibration source used by AP&L. New air filter efficiency curves will include Sr-90 and Cs-137 to compensate for the energy' differences.

3.0 PROGRAM TECHNICAL DESCRIPTION i

3.1.Sk1PLE HANDLING AND TREATMENT

'O Once a representative sample is collected and delivered to the l'aboratory, the laboratory staff is responsible for properly treating and storing the sample. Often samples collected in an environmental survey require treatment because they are not physically ready for analysis. Tr'eatment of the sample after it is received depends on the sample itself and the analyses to be performed on it. Most treatment and handling techniques have been established and well known for many years. ,

a-Water Samples Generally, water samples are acidified when collected. Samples for tritium anal 9ses should not be stored in polyethylene bottles for more than 3 or 4 months because water can evaporate through the polyethylene. 'If the samples are to be stored for any length of time, carrier or complexing agents should be added to prevent adsorption of-trace metals on .the storage containers.

I L

~

_ _ , _ _, s. . . ,- ;k- %* t ' ' Y

Air Filters The air filter must be handled with care when heavy dust load pgs is observed because particulate matter is easily removed from the filter.

Air filters are often received by the laboratory in plastic envelopes; some extremely low-level analyses may require analysis of the envelope in which the sample arrived as well as the sample itself.

Milk Milk samples are usually refrigerated until analyses can be performed.

If the analyses will be delayed for more than a few days, a preservative (formalin) is added to inhibit bacterial growth and retard spoilage. Milk samples that are to be analyzed for I-131 I have 100 m1 formalin added to avoid binding of the iodine that may occur with smaller levels of formalin.

Soil and Bottom Sediments Soil samples are dried, pulverized, and sieved before analysis.

Further thorough mixing is required to ensure a homogeneous sample.

Other Samples Perishable samples are preserved by refrigeration or freezing.

Vegetation and other samples may need to be dried, pulverized, or ashed before analysis, and after analysis for long-term storage.

3.3 DETERMINATION OF GROSS ALPHA-AND/0R GROSS BETA ACTIVITY IN WATER SAMPLES (SUSPENDED AND DISSOLVED PORTIONS)

This describes the process used to measure the overall alpha and beta radioactivity of water samples without identifying the radioactive species present. No chemical separation techniques are involved. Two hundred ml of the sample is evaporated in a beaker at approximately.

100 C. The residue is transferred and dried and in a 2-inch stainless steel planchet.

The planchets are counted for 100 minutes in a low-background alpha-beta counting system. Calculation of activity includes a self-absorption correction for counter efficiency based on the weight of residue on each planchet.

1 3.5 ANALYSIS OF SAMPLES FOR 10 DINE-131 Milk or Water Up to four liters of sample are thoroughly mixed with a stable iodine carrier solution. The sample is then allowed to flow through an anion exchange resin column to remove iodine from the sample. The iodine is then stripped from the resin with sodium hypochlorite solution, is reduced with hydroxylamine hydrochloride and is. extracted into carbon tetrachloride as free iodine. It is then back-extracted into sodium bisulfite solution and is precipitated as silver iodide. The precipitate is weighed for chemical yield and is mounted on a stainless steel planchet for low-level beta counting. The chemical yield is corrected by measuring the stable iodide content of the milk or the water with a specific ion electrode.

3.7 CHARC0AL CARTRIDGES Charcoal cartridges are counted in a Marinelli Beaker, with one cartridge positioned on the face of a Germanium detector and up to six cartridges on the side of the Germanium detector. Each Germanium detector is calibrated for both positions. The detection limit is determined for I-131 of each charcoal cartridge, assuming no positive results for I-131, for each unique cartridge from the volume of air which passed through it. If Iodine-131 is observed in the screening count of a set of cartridges, each charcoal cartridge is then counted separately, positioned on the face of the detector. A separate counting geometry has also been established for each Germanium !

detector.

Air Particulate The four or five (depending on the calendar month) air particulate filters for a monthly composite for each field station are stacked one on top of another and then counted for at least four hours with a shielded Germanium detector coupled to a multi-channel analyzer.

A computer software program defines peaks by certain changes in the slope of the spectrum. The program also compares the energy of each peak with a library of peaks for isotope identification and then performs the radioactivity calculation using-the appropriate fractional

accuracy: A measure of the agreement between observed and accepted values, systematic error: Errors that may be traced to the personal errors of the analyst, instrumental errors, errors that are inherent in the analytical methodology, or a combination of these.

Accuracy is a measure of this type of error.

random error: The necessity for making estimations is inherent in the process of collecting data for the measurement of any quantity. For this reason, any measurement will be uncertain, in an amount that depends on the relative magnitude of the estimations involved in its evaluation.

Careful experimental design can reduce this uncertainty; however, small irreducible variations will remain. Since radioactive decay is a random process, any counting measurement will have a random error associated with it.

Precision measures this type of variability or error, bias: The difference between the average of a set of test results and the accepted value. Bias usually is indicated only when a consistent difference is observed over time and can be corrected for by the application of appropriate correction factors. Bias is a measure of the systematic error.

exp(-Aat) where:

LLD is the lower limit of detection as defined above (as pCi per unit mass or volume) s b is the standard deviation of the background counting rate or of the counting rate of a blank sample as appropriate (as counts per minute)

E is the counting efficiency (as counts per transformation)

V is the sample size (in units of mass or volume) 2.22 is the number of transformation per minute per picocurie Y is the fractional radiochemical yield (when applicable)

Il

A is the radioactive decay constant for the particular radionuclide at is the elapsed time between sample collection and analysis-The value of sb used in the calculation of the LLD for a detection system shall be based on the actual observed variance of the background counting rate or of the counting rate of the blank samples (as appropriate) rather than on an unverified theoretically predicted variance. In calculating the LLD for a radionuclide determined by gamma-ray spectrometry, the background shall include the typical contributions of other radionuclides normally present in the sample (e.g., potassium-40 in milk samples). _( See Table 3.9.1) lIi

4.0 1985 LAND USE SURVEY In accordance with Technical Specification 3/4 12.2 for ANO Unit-2, a land use survey has been conducted and a garden has been located in each of the 16 meteorological sectors surrounding Arkansas Nuclear One (ANO). The distances for 15 of the gardens range from 0.65 miles to 4.8 miles from the plant site. These gardens meet the 5-mile requirement as outlined in the Tech Spec. A milk animal survey was conducted inside 5 miles of ANO were observed. Milk animal locations are given in Table 3 and 4. Residences nearest ANO within each section are given in Table 2.

A relative deposition rate in units of recipitical square meters (m 2) has been calculated for each garden using the methodology outlined in Reg. Guide 1.111. From Figure 6 of this Reg. Guide, a relative deposition in m ~1 vs distance from the plant was obtained. An assumption of a ground level release was made in the absence of any data to support an elevated release. This should provide a conservative estimate of the deposition rates at locations close to the point of release (the plant site). Wind frequency values are from the ANO-1 FSAR Table 2-16. This represents the fraction of the total annual release transported into the sector assuming a uniform wind field. It is also assumed that the effluent concentration in a given sector is uniform across the sector at a given distance. Table 1 presents the relative deposition rates for each garden location. Also presented are the values used to calculate the deposition rate.

~,,

i 4

During a given time period the source term will be equal for all

, locations of interest. Therefore,'a comparison of projected deposition at each location can be made by comparison of each location's deposition rate.

l l The two gardens with the highest-deposition rate (sectors 13,W and i

j 8,SSE) are already being sampled as indicator locations. The third location serves as a control. Therefore, no change in Food Product j sampling sites is necessary.
