ABSTRACT This report is issued pursuant to Waterford 3 Technical Specification 6.9.1.7. Its purpose is to discuss the Waterford 3 Radiological Environmental Monitoring Program (REMP), present the results of the program for the year of 1995, and evaluate the radiological impact on the environment resulting from plant operation.

98 The Waterford 3 REMP collected data on environmental radioactivity levels around the Waterford 3 nuclear power plant. These levels were determined by analyzing samples of air, water, shoreline soil, fish,

- vegetation, and milk from various locations around the facility. Based on the evaluation of the environmental data collected, the operation of Waterford 3 exhibited no discernable impact on the levels of radioactivity in the environment during 1995.

1.0 INTRODUCTION

This report describes the Radiological Environmental Monitoring Program (REMP) for the Waterford 3 Steam Electric Station and discusses the results 2

obtained during the calendar year 1995. The results discussed in this report were used to evaluate the radiological environmental impact from the operation t

of Waterford 3. The submission of this report to the Nuclear Regulatory Commission (NRC) fulfills the requirements pursuant to Waterford 3 Technical Specification 6.9.1.7.

1.1 Program and Report Objectives The objective of the monitoring program is to evaluate the radiological environmental impact of the plant. In order to conduct this evaluation, the data analyses and interpretations contained in this report fulfill the following specific objectives:

a.

to identify any radioactive materials or radiation in the environment associated with plant operation, b.

to compare the results obtained during the reporting period with past operational and pre-operational data and identify any trends associated with accumulation of radioactivity in the environment; and 3

c.

to verify compliance with federal regulatory requirements.

1.2 Plant and Site Description Waterford 3 employs a pressurized water reactor for the production of 4

approximately 1153 gross (1104 net) megawatts of electricity. The station uses a flow of water obtained from and discharged to the Mississippi River for condenser cooling. On March 4,1985, the unit achieved initial cnticality.

The plant is located on the west bank of the Mississippi River at River Mile 129.6 between Baton Rouge and New Orleans, Louisiana. The site is in l

the northwestern section of St. Charles Parish approximately 3 miles southeast of the St. John the Baptist Parish boundary between Killona and Taft. The Mississippi River is the closest prominent natural feature; other features include Lac des Allemands, about 5.5 miles southwest of the site, and Lake Ponchartrain, about 7 miles northeast of the site.

Most of the man-made features are located on the narrow strip of land between the Mississippi River and the wetlands. Specifically, several industrial facilities including Waterford 1 and 2 Steam Electric Stations (0.4 miles northwest), Little Gypsy Steam Electric Station (0.8 miles northeast), IMC Agrico, a fertilizer manufacturer (0.6 miles east 1

i southeast), Oxychem Chemical Company (0.8 miles east southeast), and Union Carbide, a chemical manufacturer (1.2 miles east southeast) are operating in the area.

l Major urban centers in the region include New Orleans (approximately 25 miles east) and Baton' Rouge (approximately 50 miles west northwest).-

L Communities near the site in St. Charles Parish include Killona (0.9 miles west northwest), Montz (1.0 miles north), Norco (2.5 miles east), Hahnville (3.7 miles east southeast), and Destrehan (6.3 miles east southeast).

Laplace (4.7 miles north) is located in St. John the Baptist Parish.

2.0 PROGRAM DESCRIPTION A general summary of the REMP is given in Table 2.1; brief descriptions and locations of the sampling stations are presented in Table 2.2. In addition, station-locations are illustrated in Figures 2.1 through 2.3 A more detailed description of the REMP is provided below.

2.1 History and Development The Waterford 3 REMP evolved from the Pre-operational Environmental Radiological Surveillance (PERS) program (1978-1982) and was initiated in April of 1983. Equipment, procedures, techniques, and sampling

^

locationa used during the pre-operational survey were incorporated into the operational program. Further, the environmental data collected during 3

the first two years of the REMP (1983 and 1984), prior to initial criticality, were used to supplement the baseline established during the PERS Program.

2.2 Responsibilities Waterford 3 personnel are responsible for implementing and ensuring that the REMP complies with federal regulatory, Technical Specification, and Offsite Dose Calculation Manual (ODCM) requirements. Responsibilities of Waterford 3 personnel include collecting (with the exception of fish samples), preparing, and shipping of environmental samples; conducting environmental dosimetry measurements; reviewing analytical results reports; and preparing and submitting the annual Radiological Environmental Operating Report and other relevant reports to the Nuclear Regulatory Commission.

i The primary contractor, Entergy Services, Inc. (ESl) System Chemistry located in Little Rock, Arkansas, is responsible for performing radiological analyses; conducting initial data review; preparing results reports; and overseeing laboratory quality assurance and control. Additionally, a separate contractor, the Fisheries Co-operative Extension Service of Louisiana State University, is responsible for the collection of fish samples.

2.3 Sample Collection and Handling Procedures Sample types, location, collection frequency, and the analyses performed are summarized in Tables 2.1 and 2.2. The information contained in these tables is based on requirements specified in Table 5.8-1 of the.

~

Waterford 3 ODCM. Location maps of the sampling are illustrated in Figures 2.1 through 2.3. Any stations deviations (i.e., unavailable.

samples and missed lower limits of detection) or changes made to the REMP during 1995 are discussed in Section 3.6.

The environmental samples collected are classified into four general categories according to exposure pathways: direct radiation, airbome,.

waterbome, and ingestion. Sample collection and handling procedures are described in the following sections. The descriptions are intended to provide a concise procedural overview rather than a step-by-step description.

2.3.1 Direct Radiation Exposure Pathway Samples Integrated external gamma exposure, determined using Panasonic multi-element thermoluminescent dosimeters (TLDs), was measured at thirty-one locations as follows:

a.

an inner ring of stations, one in each of the sixteen

~

meteorological sectors, in the general area of the site boundary; b.

an outer ring of stations, one in ten of the sixteen meteorological sectors, in the six to eight kilometer range from the site; and c.

the balance placed in areas of special interest (e.g.,

population centers, schools, etc.) with one area serving as a control.

The TLDs were exchanged and analyzed quarterly by Waterford 3 personnel.

2.3.2 Airborne Exposure Pathway Samples Samples of airborne particulates and radiolodines were collected at four indicator stations (APP-1, APQ-1, APG-1, APC-1) and one

~

control station (APE-30). Low-volume air pumps and flow totalizers in weather proof shelters provided continuous air sampling.

3

l*

i Using the sampling device described above, airborne particulate samples were obtained on a filter and collected weekly by Waterford 3 personnel for shipment to the contract laboratory for gross beta analysis. The filters were composited quarterly by the contract laboratory for isotopic analysis by gamma spectroscopy.

Airborne iodine sampling was done in conjunction with air particulate sampling using a charcoal cartridge to collect iodine.

The cartridges were collected weekly by Waterford 3 personnel and sent to the contract laboratory for iodine-131 analysis by gamma spectroscopy.

i.

2.3.3 Waterborne Exposure Pathway Samples

. Because the plant discharges into the Mississippi River, the major source of drinking water in the vicinity of Waterford 3, water samples taken from the Mississippi River were designated as both drinking and surface water samples.

i

~

Composite drinking / surface water samples were obtained biweekly from the Mississippi River using automatic composite samplers placed at one upstream (DWP-7/SWP-7) and two downstream (DWG-2/SWG-2, DWE-5/SWE-5) locations. Hydrochloric acid was added to each sample prior to shipment. The contract laboratory analyzed the biweekly samples for lodine-131, composited them monthly for gross beta and gamma spectroscopy, and composited them quarterly for tritium analysis.

Due to the high water table resulting from shallow aquifers in the i

vicinity of the site, drainage canal sampling represents groundwater discharge. Groundwater was obtained quarterly by grab sampling from one sampling location (GWK-1). Again, hydrochloric acid was added to the sample prior to shipment to the contract laboratory for tritium and gamma spectroscopy analyses.

)

Shoreline sediment samples were obtained semi-annually from a sampling station at each plant discharge point. Station SHWE-3 is located downstream on the shoreline of the Mississippi River; station SHWK-1 is on the shoreline of the 40-Arpent canal. The samples were shipped without further processing, 2.3.4 Ingestion Exposure Pathway Samples Milk samples were collected semi-monthly from one indicator location (MKQ-5) and one controllocation (MKQ-45). Sampling of the control station was performed by Louisiana Radiation Protection Division personnel. Although one additionalindicator location was identified (MKQ-1), no samples were available from 4

O this location during 1993 (see Section 3.6). Finally, formaldehyde -

was added as a preservative to all samples prior to shipment.

Upon arrival at the laboratory, iodine-131 and gamma spectroscopy analyses were performed.

Fish samples were collected bi-annually from the Mississippi River upstream (FH-1) and downstream (FH-2) from the plant. A contractor performed the sampling by netting. Subsequently, the fish were segregated by species and location prior to delivery to Waterford 3. The samples were shipped frozen for analysis by gamma spectroscopy.

- The Waterford 3 ODCM, Section 5.8.1, requires broad leaf vegetation to be sampled from 3 locations within 5 miles of the j

plant in the event milk samples are unavailable. Since milk samples were collected from only one sampling location within five miles of Waterford 3, broad leaf vegetation was sampled monthly at I

I two indicator locations (BLQ-1 and BLB-1) and one control location (BLK-15). The samples were shipped without further processing.

Food product sampling was not required because no areas surrounding the plant were irrigated with water in which plant wastes are discharged. However, food products grown within the site boundary were collected to demonstrate the absence of radionuclide accumulation.

These food product samples (sugarcane) were collected at the time of harvest from two locations (FPG-1 and FPP-1) by normal harvesting techniques and shipped without further processing.

lodine-131 and gamma spectroscopy analyses were performed.

2.4 Analytical Procedures 2.4.1 Gross Beta Analysis in Air Particulates l

After allowing for the radon-222 and radon-220 daughter products to decay, the particulate filters were counted in a gas-flow

[

proportional counter.

2.4.2 Gross Beta Analysis in Water 4

A known volume of water, usually 200 milliliters, was reduced by evaporation, transferred to a two inch diameter planchet, and evaporated to dryness. The planchet was counted for 100-200 minutes or until the required LLD is achieved in an automatic l-alpha-beta counter.

1 1

5 l

s,v-

2.4.3 Tritium Analysis in Water A known volume of water, 5 milliliters, was added to 15 milliliters of liquid scintillation solution in a 25 milliliter vial. The sample was counted for 500 minutes in a liquid scintillation counter.

2.4.4 lodine-131 Analysis in Milk and Water Approximately four liters of sample were mixed with a stable iodine carrier solution and eluded through an anion exchange resin column to remove iodine from the sample. lodine analysis was performed using gamma spectroscopy. The time between sample i

receipt and analysis, sample amount, and count times were ~

adjusted in order to attain the required LLD. The chemical yield was corrected by measuring the stable iodide content of the milk or water with a specific lon electrode.

I 2.4.5 Gamma Spectroscopy Analysis l

Air particulate filters and iodine cartridges, water, milk, broadleaf vegetation, sediment, food products and fish samples are prepared in containers, using the appropriate geometry for its sample type.

Secondly, the sample is counted in a shielded high purity 4

l germanium (HPGE) or germanium lithium (GeLi) detector coupled to a computer based data acquisition system that performs pulse height analysis.

~ The computer software program defines peaks by changes in the slope of the spectrum, compares each specific peak energy with a i

library of pes.ks for isotopic identification, and performs the i

radioactivity calculation using the apropriate fractional gamma ray abundance, half life, detector efficiency, and net counts in the peak 4

region.

lodine analysis was performed using gamma spectroscopy. The i

time between sample receipt and analysis, the sample size and count times were adjusted in order to attain the required lower limit of detection.

I 2.4.6 Environmental Dosimetry 4

)

Model UD-814 Panasonic thermoluminescent dosimeters (TLDs) that contain one lithium borate and three calcium sulfate phosphor elements were used for environmental dosimetry. However, only i

the calcium sulfate phosphor elements were used for analysis. For i

placement in field, two annealed dosimeters are placed inside a plastic bag and mounted in an aluminum frame. The dosimeters are checked monthly and exchanged for analysis each quarter 6

I

_=

using an automatic TLD reader manufactured by Panasonic (Model l

UD-710).

2.4.7 Lower Limits of Detection (LLD)

The minimum sensitivities for the analytical procedures are j

reflected by the Lower Limits of Detection (LLD) values presented in Table 2.3 from Table 5.8-3 of Waterford 3 ODCM. The LLD's are a priori estimates based on assumed sample volumes, counting times, detector efficiencies, etc. Analyses that could not achieve l

these lower limits of detection are discussed in Section 3.6.

2.5 Laboratory Quality Assurance During 1995, the ESI System Chemistry laboratory performed between i

5% and 10% of all analyses for quality assurance purposes. Spiked and blank samples were prepared in-house. In addition, the laboratory participated in the EPA Radiological Interlaboratory Comparison (cross-check) Program.

j This quality assurance program satisfies the requirements of the Waterford 3 ODCM, Section 5.8.2, for participation in an interlaboratory comparison program. The program involved analyses on various sample media typically found in the REMP. As a result of participation in the program, an objective measure of analytical precision and accuracy was obtained. In the event that results obtained by ESI System Chemistry were not within control limits (3 standard deviations), an investigation was conducted to determine the cause, and corrective action was taken to prevent a recurrence. Table 2.4 lists the 1995 results of the laboratory's i

participation in the cross-check program.

• Each isotope measured by ESI was 14-33% higher than values reported by the U.S. EPA. When EPA published the results on 2/14/95, the ESI cross check sample had been disposed of. Because the EPA sample was inadvertently disposed, no follow-up action could be taken on that particulate sample. Since all measurements made by ESI were higher than the EPA values, it appears that a dilution error when preparing the sample was the cause for the discrepancy between ESI values and the EPA values. A new liquid standard was purchased from Analytics, Inc. in March 1995 and new efficiency curves were calculated using a 3.5 liter Marinelli geometry. There were no appreciative differences between the efficiency curves calculated before and after the Nov 4,1994 cross-check sample was analyzed. A 3.5L resin standard prepared by Analytics, Inc. was analyzed, resulting in efficiency curves which were approximately 90 percent as efficient as deiomzed water. 7hese results are theoreucally in agreement since the Analytics, Inc. resin standard has a density of 1.15 kg/L. No data from gamma wa%

would be affected by this apparent dilution error.

3.0 DISCUSSION OF RESULTS i

Analytical results for the year 1995 are discassed in this section by exposure pathway, sample type, and analysis performed. Further, analytical results focusing only on man-made radioactivity are summarized in Appendix A; data for the individual analyses are presented in the tables of Appendix B.

i j

3.1 Direct Radiation Exposure Pathway The average exposure rates measured by thermoluminscent dosimeters (TLDs) at both control and indicator stations were 13,12,13, and 12 mrem / standard quarter for the first, second, third, and fourth quarters of 1995, respectively. The average exposure rate of the 120 indicator TLD l

locations was 13 mrem / standard quarter compared to 11 mrem / standard quarter average exposure rate at the control location. The lowest and highest individual exposure rates were 8 mrem / standard quarter (C-1,2nd and 3rd quarters) and 19 mrem / standard quarter (P-8,1st quarter) for all locations. Table 3.1 compares the indicator TLD results by directional sector and distance from the facility. A comparison of directional sectors Indicates the highest average exposure rate in 1995 to be 14 mrem / standard quarter in Sectors D, Q, and R.

The average exposure rates during 1995 are consistent with those from the pre-operational program and the previous five years of operation j

i, (Figure 3.1). In particular, the pre-operational survey indicates that exposure rates ranged between 11 and 33 mrem / standard quarter with an average of 20 mrem / standard quarter. Similarly, the range indicated during the previous five years of operation was from 7 to 23 j

1 mrem / standard quarter with an average exposure rate of 13 mrem / standard quarter.

l 3.2 Airborne Exposure Pathway 3.2.1 Airborne Porticulates Gross beta activity ranged from 0.004 pCl/m (APG-1,7/11-7/18)for to 0.035 pCl/m (APQ-1,4/25-5/2) with an average of 0.017 pCi/m i

258 measurements from all five locations. The average gross beta activity for the indicator (APG-1, APQ-1 APP-1, APC-1) locations was 0.017 pCl/m compared to 0.016 pCi/m at the control (APE-j

30) location.

The gross beta activity results obtained during 1995 are consistent with those from the pre-operational program and the previous five years of operation (Figure 3.2). Specifically, the pre-operational l

i l

I 21 4

- - - ~ - - -

1 L

i survey indicates that in periods not significantly influenced by nuclear weapons testing the gross beta activity ranged between 4

0.007 and 0.48 pCi/m with an average of.08 pCi/m'. Similarly, the range indicated during theprevious five years of operation was i

from 0.004 to 0.039 pCi/m with an average activity of 0.017 j

pCi/m'.

l 3.2.2 Airbome lodine 3

l All of the 258 airbome iodine-131 results were below the calculated 2

lower limit of detection (LLD). The sample LLD variability (0.012 to 8

O.032 pCi/m ) was due primarily to the difference in air sample 4

volumes.

i f

3.2.3 Gamma Isotopic Analysis i

f Gamma spectroscopy results of the twenty air sample quarterly composites indicate that no man-made radionuclides were detected above their respective lower limits of detection.

)

3.3 Waterborne Exposure Pathway 3.3.1 Drinking / Surface Water As mentioned previously, drinking water samples also serve as

^

surface water samples for Waterford 3. Therefore, monthly and quarterly gamma spectroscopy analyses of drinking water and quarterly tritium analyses also satisfy the surface water sampling requirement.

Seventy-eight composite drinking / surface water samples were l

analyzed by gamma spectroscopy for iodine-131 (Table B-4). All of 4

the 78 composite sample iodine-131 results were below the calculated lower limit of detection (LLD).

j j

Gross beta activity was detected in thirty-six of the forty-two

~

composites with a range of 1.3 (DWE-5,2/21-3/21) to 12.1 (DWG-2,1/24-2/21) pCi/l and an average activity of 3.9 pCi/l. The average E

activity for the control location, DWP-7, was 3.7 pCi/i compared to the averages of 4.9 and 3.2 pCi/l for indicator stations DWG-2 and i

i DWE-5, respectively.

1 Analyses for gross beta in drinking / surface water were not performed during the pre-operational survey. However, in order to 1

fulfill comparison requirements,1995 data will be compared to data from the 1983 report and the previous five years of operation.

b 1

4 22

p i-The gross beta activity results obtained during 1995 are consistent 4

with those from the 1983 reporting period and the previous five years of operation (Figure 3.3). In particular, the 1983 survey indicates that in peilods not significantly influenced by nuclear weapons testing the gross beta activity ranged between 2.9 and 14.0 pCill with an average of 7.0 pCl/l. Similarly, the range indicated during the previous five years of operation was from 1.1 l

to 12.4 pCi/l with an average activity of 4.4 pCi/l.

Tritium analysis of drinking / surface water samples indicate that all of the twelve measurements were below the calculated LLD.

t 3.3.2 Groundwater Four groundwater samples were collected from one sampling location, GWK-1, and analyzed for tritium and gamma emitters.

Results from all gamma and tritium analyses indicate that all measurements were below the calculated LLDs.

a The tritium concentrations detected in 1995 are consistent with those from the pre-operational program and the previous five years of operation. In particular, the pre-operational survey indicates that tritium concentrations in groundwater samples ranged between 50 and 180 pCl/l with an average of 121 pCi/l. Similarly, the range indicated in the previous five years of operation was from 270 to j

650 pCl/l.

3.3.3 Shoreline Sediment Four shoreline soil samples were collected from the following i

sampling locations: two samples from the Mississippi River shoreline downriver of the plant (SHWE-3) and two samples from j

the shoreline of a drainage canal (SHWK-1).

i Naturally occurring radionuclides including potassium-40, radium-226, and actinium-228 were detected in all of the samples.

Cesium-137, a man-made nuclide was detected in samples from 1

station SHWK-1 at concentrations of 31 and 34 pCi/kg (dry) and i

from SHWE-3 at concentrations of 44 and 45 pCi/kg (dry). No l

other man-made radionuclides were detected in any of the samples.

]

The cesium-137 results obtained during 1995 are consistent with

.those from the pre-operational program and the previous five years i

of operation, in particular, the pre-operational survey indicates that cesium-137 was detected in 9 of 14 soil samples at concentrations 23

. -. - -.--=

l ranging between 30 and 890 pCi/kg(dry) with an average concentration of 164 pCi/kg (dry). Similarly, the range indicated

~

during the previous five years of operation was from 18 to 66 pCi/kg (dry) with an average activity of 45 pCi/kg (dry). Further, i

studies in Louisiana indicate that cesium-137 is commonly found in i

soils and sediments as a result of atmospheric weapon testing.

Because the cesium-137 levels are consistent with pre-operational -

l values, the cesium-137 levels detected in 1995 are more than likely attributable to weapon testing fallout.

1 3.4 Ingestion Exposure Pathway 2

3.4.1 Milk Forty-eight milk samples were collected from two sampling locations and j

analyzad by gamma spectroscopy and a radiochemical procedure for j

iodine-131. Naturally occurring potassium-40 was detected in all i

samples. Results from iodine-131 analyses indicate thaf. all i

measurements were below the calculated LLD. Further, cesium-137 was i

detected in two control samples (MKQ-45,7/18 and 10/17) at l

concentrations of 2.0 and 3.0 +/- 2.0 pCi/l. However, the levels of cesium-j in these control samples are below both the reporting levels and the LLD j-required by the Waterford 3 ODCM and have a high level of statistical uncertainty associated with them.

3.4.2 Fish Sixteen fish samples, eight upstream and eight downstream of the j

plant were collected and the edible portions analyzed by gamma l

spectroscopy. Only naturally occurring potassium-40 was detected above the lower limits of detection in any samples.

i 3.4.3 Broad Leaf Vegetation Thirty-six broad leaf vegetation samples were collected and l

analyzed by gamma spectroscopy and a radiochemical procedure j

for iodine-131. Naturally occurring radionuclides were detected in all of the samples; however, no man-made radionuclides were j

detected above their calculated LLDs.

I 3.4.4 Food Products

)

Two food products samples were collected and analyzed by gamma spectroscopy and a radiochemical procedure for iodine-131. Naturally occurring potassium-40 was detected in all the l

samples; however, no man-made radionulides were detected i

above their calculated LLDs.

3.5.2 Comparing Two Sample Population Means The means of two sample populations are compared for statistical

difference using the standard "t" test. The use of the test requires the assumption that the data within the populations are normally distributed and that the true standard deviations of the mean are i

equal for both populations. The standard "t" test tests the hypothesis that the true means of both populations are equal. The "t" value can be calculated from the equation below (obtained from the CRC Standard Mathematical Tables,26th Edition (1981)).

j s = standard deviation of second data set.

y 1

The calculated "t" value is used to test the hypothesis that the true mean of the first population (m,) is equal to the true mean of the second population (m ) assuming that the true standard deviations y

_of both populations are equal (m, = m ). The calculated "t" value y

is compared to a tabular "t" value such that:

a. if t > t p,n then reject the hypothesis when m > m,

y y

b. if t < -t p,n then reject the hypothesis when m, < m,

y

c. if t > t pa,n then reject the hypothesis when m, = m,

y where t pa,n and t p,n are the tabular "t" values, with a preselected error (5%), confidence level (1 - p) or (1 -

p/2), and degrees of freedom n (n=n,+n -2 for y

Equation F-3 and n=N-1 for F-4, respectively).

Tabular values of the "t" were obtained from the CBC Standard Mathematical Tables. 26th Edition (1981).

3.5.3 TLD Measurements i

TLD stations were categorized by distance into three groups: 0-2 miles,2-5 miles, and >5 miles from the plant. A statistical analysis 4

using the standard "t" test (described above) was performed comparing average exposure rates from 0-2 miles and 2-5 miles to the average exposure rate at >5 miles. In short, results indicate l

that the average exposure rates at 0-2 miles and 2-5 miles are statistically the same as the rates at >5 miles. Table 3.2 summarizes the results of this ant!ysis.

3.5.4 Gross Beta Activity on Air Particulate Filters Additionally, the standard "t" test was used to compare average gross beta activity from each indicator station to the average gross beta activity at the control station. The results from this test show average activity detected at all indicator stations (APG-1, APQ-1, APC-1, and APP-1) to be statistically the same as the activity l

26

1 detected at the control station. Table 3.3 summarizes the results of-this analysis.

3.5.5 Gross Beta Activity in Monthly Drinking Water Composites j

Finally, t'he standard "t" test was used to compare average gross beta activity from the two indicator stations to the average gross beta activity from the control station. The results from this test show average activity at indicator stations (DWG-2 and DWE-5) are statistically the same as the average activity detected at the control station. Table 3.4 summarizes the results of this analysis.

3.6 Deviations from the REMP 3.6.1 Unavailable Samples Two air samples were missed during the 1995 reporting period.

One of the air samples was unavailable because the air sample heads were inadvertantly switched, while the other sample was missed due to a disconnection in the sample line.

(

Milk samples were not available during 1995 from the animal owners at station MKQ-1 since the cows are not currently producing milk for human consumption. With the absence of milk 4

samples at these stations, broad leaf vegetation sampling was P

performed. These results are summarized on Table 3.5.

3.6.2 Lack of Sample Continuity Two air samples failed to meet the requirement for sample continuity as a result of air sample pump failures, i

3.6.3 Missed Lower Limits of Detection All lower limit of detection requirements were met for 1995.

3.7-Annual Land Use Census 1

)

In compliance with Waterford 3 ODCM, the annual land use census was conducted on August 23,24, and 25,1995. The nearest residence, garden, and milking animalin each sector within a five mile radius of the plant were located by visual inspection and verbal inquiry.

While residence locations remained unchanged for 1995, minor changes in garden locations were observed as recorded on Table 3.6. Additionally, large tracts of sugar cane are still being cultivated near the plant and remain classified as food products.

27 4

One new location for milk cows and one new location for goats was identified; however, in all cases it was determined that the animals are not currently producing milk for human consumption. This information was ascertained by verbalinquiry with the owners of the animals. As a result of the interviews, Waterford 3 personnel obtained a verbal agreement that the animal owners will sell milk samples to Waterford 3 in the event of a radiological emergency to provide additional data for analysis of environmentalimpact i

4.0 CONCLUSION

S

)

The radiological environmental data collected during 1995 are consistent with the data obtained during the previous five years of plant operation (1990-94), the first two years of the REMP prior to Waterford 3 initial criticality (1983-84), and the Pre-operational Environmental Radiological Surveillance (PERS) Program (1978-82). The only man-made radionuclide detected in the environmental samples analyzed during 1995 was cesium-137, i

Cesium-137 was detected in four shoreline soil samples. Studies in Louisiana indicate that cesium-137 is commonly found in soils and sediments as a result of fallout from 3

nuclear weapons testing, in addition, the detected concentrations were consistent with j

pre-operational levels and the levels detected in the previous five years of operation.

Further, the concentrations detected in both instances were lower than the required LLD and well below levels requiring notification.

l Analyses of milk samples indicated cesium-137 in two samples collected from the control location in July and October of 1995. The activity detected in both instances was at levels below the required LLD and well below reporting levels defined in the i

Waterford 3 ODCM. In addition, cesium-137 concentrations detected in 1995 milk samples are consistent with the levels indicated in the pre-operational program and the levels detected in the previous five years of operation. Further, statistical errors l-associated with the indicated concentrations are higher than would be expected with j

true activity and may be artifacts of counting statistics.

i ~

In conclusion, based on the evaluation of the REMP data collected during 1995 the operation of Waterford 3 had no discernable radiological impact on the environment.
