1.0 INTRODUCTION
This report describes the Radiological Environmental Monitoring Program
, (REMP) for the Waterford 3 Steam Electric Station and discusses the results obtained during the calendar year 1994. The results discussed in this report were used to evaluate the radiological' environmental impact from the operation 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
- 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 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 criticality. 1
l i The plant is located on the west bank of the Mississippi River at l River Mile 129.6 between Baton Rouge and New Orleans, Louisiana. l The site is in the northwestern section of St. Charles Parish l approximately 3 miles southeast of the St. John the Baptist Parish boundary between the towns of 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 I 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 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. Major urban centers in the region include New Orleans (approximately 25 miles east) and Baton Rouge (approximately 50 miles west northwest). 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. t 2
. e, .
t , 2.1 . History and Development 1 The Wat'erford 3 REMP evolved from the Pre-operational l Environmental _ Radiological Surveillance (PERS) program'(1978-1982) l and was initiated in April of 1983. Equipment, procedures, !
. techniques, and sampling locations used during the pre-operational !
survey.were incorporated into the operational program. Further, ! the environmental data collected during the first two years of the l
~
REMP (1983 and 1984), price to initial criticality, were used to supplement the baseline established during the PERS Program, j 2.2 Responsibilities Waterford 3 personnel are responsible for implementing and ensuring that the REMP complies with federal regulatory, Technical- j Specification, and Offsite Dose Calculation Manual (0DCM) l requirements. Responsibilities of Waterford 3 personnel include. j collecting (with the exception of fish samples), preparing, and l shipping of environmental samples; conducting environmental j dosimetry measurements; reviewing analytical results reports; and ; , preparing and submitting the annual Radiological Environmental ! Operating Report and other relevant reports to the Nuclear i Regulatory Commission. ! The primary contractor, Entergy Services, Inc. (ESI) System , Chemistry located in Little' Rock, Arkansas, is responsible for l performing radiological analyses; conducting initial data review; i preparing results reports; and overseeing laboratory quality l assurance and control. Additionally, a separate contractor, the Fisheries Co-operative Extension Service of Louisiana State University, is resconsible for the collection of fish samples. i 3
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 i 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 1994 are discussed - in Section 3.6. , The environmental samples collected are classified into four general categories according to exposure pathways: direct radiation, airborne, waterborne, 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.
3 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. 4
2.3.2 Airborne Exposure Pathway Samples Samples of airborne particulates and radioiodines 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 i continuous air sampling. 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. ,
. l 2.3.3 Waterborne Exposure Pathway Samples Because the plant discharges into the Mississippi River, the I major source of drinking water in the vicinity of Waterford l 3, water samples taken from the Mississippi River were l designated as both drinking and surface water samples. !
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 iodine-131, composited them monthly for gross beta and gamma spectroscopy, and composited them quarterly ; for tritium analysis. 1 5 i
i
'Due to the high water. table resulting from shallow aquifers '
in the vicinity of the site, drainage canal sampling , represents groundwater discharge. Groundwater was'obtained l quarterly by grab sampling from one- sampling location (GWK- l
, ,- 1). Again, hydrochloric acid was added to the sample prior ;
to shipment to the contract laboratory for tritium and gamma j spectroscopy analyses. L Shoreline sediment samples were obtained semi-annually from : ! a sampling station at each plant discharge point. Station l SHWE-3 is . located downstream on the shoreline of the. .l l Mississippi River; station SHWK-1 is on the shoreline of the 1 40-Arpent canal. The samples were shipped without-further processing. l~ 2.3.4 Ingestion Exposure Pathway Samples : l l' Milk samples were collected semi-monthly from one indicator 'l l location (MKQ-5) and one control location (MKQ-45). ; Sampling of the control station was performed by Louisiana !
. Radiation Protection Division personnel. Although one '
additional indicator location was identified (MKQ-1), no , samples were available from 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. l 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. 1 6
I l The Waterford 3 ODCM, Section 5.8.1, requires broad leaf vegetation to be sampled from 3 locations within_5 miles of the plant in the event milk samples are unavailable. Since milk samples were collected from only one sampling locatior, within five miles of Waterford 3, broad leaf vegetation was sampled monthly at 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. Iodine-131 and gamma spectroscopy analyses were i performed. 2.4 Analytical Procedures s
~
2.4.1 Gross Beta Analysis in Air Particulates 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
. 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 minutes in an automatic alpha-beta counter.
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 seintillation counter. 7
2.4.4 Iodine-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. Iodine ;
. analysis was- performed using gamma spectroscopy. The time i between sample receipt and analysis, sample amount, and. 3 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 ion electrode. 2.4.5 Gamma Spectroscopy Analysis q 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 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 library of peaks for isotopic identification,
. and performs the radioactivity calculation using the appropriate fractional gamma ray abundance, half life, detector efficiency, and net counts in the peak region.
Iodine analysis was performed using ' gamma spectroscopy. The time between sample receipt and analysis, the sample size and count times were adjusted in order to attain the required lower limit of detection. 2.4.6 Environmental Dosimetry Model 00-814 Panasonic thermoluminescent. dosimeters (TLDs) that contain one lithium borate and three calcium sulfate phosphor elements were used for environmental dosimetry. However, only the calcium sulfate phosphor elements were used for analysis. For 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 using an automatic TLD reader manufactured by Panasonic (Model UD-710). 8 L - _ _ _ _ _ _ _ _ - _ _ _ __- _ _ _-_ _ _ _ _-_-__-__
l 2.4.7 Lower Limits of Detection (LLD) The minimum sensitivities for the analytical procedures are 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 oriori estimates based on assumed sample volumes, counting times, detector efficiencies, etc. Analyses that could not achieve these lower limits of detection are discussed in Section 3.6. 2.5 Laboratory Quality Assurance During 1994, the ESI System Chemistry laboratory performed between 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. 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 1994 results of the laboratory's participation in the cross-check program. 9 i

3.0 DISCUSSION OF RESULTS Analytical results for the year 1994 are discussed 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.
3.1 Direct Radiation Exoosure Pathway The average exposure rates measured by thermoluminscent dosimeters (TLDs) at both control and indicator stations were 13, 14, 11, and 12 mrem / standard quarter for the first, second, third, and fourth quarters of 1994 respectively. The average exposure rate of the 118 indicator TLD 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 7 mrem / standard quarter (C-1 and F-9, 3rd quarter) and 18 mrem / standard quarter (R-6, 2nd quarter), respectively, 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 1994 to be 14 mrem / standard quarter in Sector G. The average exposure rates during 1994 are consistent with those from the pre-operational program and the previous five years of operation (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 24 mrem / standard quarter with an average exposure rate of 13 mrem / standard quarter. 3.2 Airborne Exoosure Pathway 3.2.1 Airborne Particulates Gross beta activity ranged from 0.004 pCi/m (APG-1,2/8-
- 2/22 and APC-1 and APE-30,2/8-2/14) to 0.039 pCi/m3(APG-1, 8/30-9/6) with an average of 0.018 pCi/m3 for 260 measurements from all five locations. The average gross beta activity for the indicator (APG-1, APQ-1, APP-1, APC-1) locations was 0.018 pCi/m3 compared to 0.018 pCi/m 3 at the control (APE-30) location.
l l 23 1 l l l
l The gross betr> activity results obtained during 1994 are consistent with those from the pre-operational program and the previous five years of operation (Figure 3.2). Specifically, the pre-operational survey indicates that in periods not significantly influenced by nuclear weapons testing the gross beta activity ranged between 0.007 and -
. 0.48 pCi/m with an average of .08 pCi/m3. Similarly, the range indicated during the previous five years of operation was from 0.003 to 0.039 pCi/m with an average activity of 0.016 pCi/m .
3.2.2 Airborne Iodine All of the 260 airborne iodine-131 results were below the calculated lower limit of detection (LLD). The sample LLD variability (0.011 to 0.041 pCi/m ) was due primarily to the difference in air sample volumes. , 3.2.3 Gamma Isotopic Analysis l 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. i 3.3 Waterborne Exoosure Pathway
. 3.3.1 Drinkina/ 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 i drinking water and quarterly tritium analyses also satisfy the surface water sampling requirement. i Seventy-eight composite drinking / surface water samples were analyzed by gamma spectroscopy for iodine-131 (Table B-4). i Iodine was detected in one indicator sample (DWE-5, 4/19-
. 5/3) and in one control sample (DWP-7, 4/19-5/3) at an average concentration of 0.2 pCi/1. Iodine-131 was detected :
in several preoperational samples at an average concentration of 0.4 pCi/1. The levels detected in the 1994 samples were well below reporting levels and the LLD required by the Waterford 3 ODCM. Additionally the high degree of uncertainty associated with these measurements could indicate that these results are an artifact of counting statistics. 24 s
h 1 Gross beta activity was detected'in thirty-one of the
~
- thirty-nine composites with f a range of 1.4;(DWG-2,: 2/8-3/8)-
to 12.4 (DWP-7, 7/26-8/23) pC1/1 and an' average activity of-4.3 pCi/1. The- average activity for the control location,' DWP-7,-was 5.1 pC1/1 compared to the averages of 3.7 and'5.2 pCi/l for indicator. stations DWG-2.and DWE-5.respectively.
)
Analyses for grose beta in drinking / surface water were not- ! performed during the pre-operational survey. However, in -)
- . order to fulfill comparison requirements, 1994 data will be' compared to data from the 1983 report and the previous five ;
years of operation. !
)
The gross beta activity results obtained during 1994 are l consistent with those from the_'1983 reporting period and the . i previous five years of operation (Figure 3.3). In I particular, the 1983 survey indicates that in periods not significantly influenced by nuclear weapons testing the -. gross beta activity ranged between 2.9 and 14.0 pCi/l with an average of 7.0 pCi/1. Similarly, the range indicated i during the previous five years of operation was from 1.1 to ; 11.7 pC1/1 with an average activity of 4.5 pCi/1. . l Tritium analysis of drinking / surface water samples. indicate j that all of the twelve measurements were below the : calculated LLD. j i
, 3.3.2 Groundwater i i
Four groundwater samples were collected from one sampling j location, GWK-1, and analyzed for tritium and gamma ; emitters. Results from all gamma and tritium ~ analyses l indicate that all measurements were below the calculated ) LLDs. l The tritium concentrations detected in 1994 are consistent I with those from the pre-operational program and the previous l five years of operation. In particular, the pre-operational l
. survey indicates that tritium _ concentrations in groundwater '
samples ranged between 50 and 180 pCi/1 with an average of 121 pCi/1. Similarly, the range indicated in the previous i five years of operation was from 270 to 650 pCi/1. i l l

3.3.3 Shoreline Sediment Four shoreline soil samples were collected from the following sampling locations: two samples from the Mississippi River shoreline downriver of the plant (SHWE-3) and two samples from the shoreline of a drainage canal
, (SHWK-1).
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 station SHWK-1 at concentrations of 62 and 33 pCi/kg(dry). No other man-made radionuclides were detected in any of the samples.
The cesium-137 results obtained during 1994 are consistent with those from the pre-operational program and the previous five years of operation. In particular, the pre-operational survey indicates that cesium-137 was detected in 9 of 14 soil samples at concentrations 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 41 pCi/kg (dry) respectively. Further, studies in Louisiana indicate that cesium-137 is commonly found in soils and sediments as a result of atmospheric weapon testing. Because the cesium-137 levels , are consistent with pre-operational values and cesium-137 has been shown to be present in most Louisiana soils, these cesium-137 levels are more than likely attributable to l weapon testing fallout. 3.4 Incestion Exposure Pathway 1 3.4.1 Milk Forty-eight milk samples were collected from two sampling locations and analyzed by gamma spectroscopy and a radiochemical
. procedure for iodine-131. Naturally occurring potassium-40 was detected in all samples. Results from iodine-131 analyses indicate i that that all measurements were below the calculated LLD.
Further, naturally occurring potassium-40 was detected in all , sample and cesium-137 was detected in two control samples (MKQ-45, I 5/31 and 6/14) at a concentration of 3.0 +/- 2.0 pCi/1. However, the levels of cesium-137 detected in these conttol samples are , below both the reporting levels and the LLD required by the l Waterford 3 ODCM and have a high level of uncertainty associated with them. 26 l
'3.4.2 Fish Sixteen fish samples, eight upstream and eight downstream of the plant were collected and the edible portions analyzed by gamma spectroscopy. Only naturally occurring potassium-40 was detected above the lower limits of detection in any . samples.
3.4.3 Broad Leaf Veaetation Thirty-six broad leaf vegetation samples were collected and analyzed by gamma spectroscopy and a radiochemical procedure for iodine-131. Naturally occurring radionuclides were detected in all of the samples; however, no man-made radionuclides were detected above their calculated LLDs. 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 samples; however, no man-made radionulides were detected above their calculated LLDs. 3.5 Statistical Analyses O 3.5.1 Calculation of the Mean and Standard Deviation , 1 The mean and standard deviation for different groups of l analyses are calculated using the following equations: ) i (F-1) !

4 l 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 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)): (F-3) X-Y 23 a5 r 35 0 f(H-l)S+H-l

. n x = number of variables in first data set, s x = standard deviation of first data set, n y - number of variables in second data set, and s y - standard deviation of second data set.
If the data from both sample populations are treated as correlated pairs, the difference between individual measurements can be examined using the statistical "t" test.
. In this case, if the true means and true standard deviations for the sample populations are equal, the difference between the correlated data points should be normally distributed about a mean of zero. The "t" value can be calculated from the following equation (obtained from the CRC 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 using the standard "t" test (described i above) was performed comparing the average exposure rates i from 0-2 miles and 2-5 miles to the average exposure rate at' !
>5 miles. In short, the results of the analyses indicate ;
that the average exposure rate at 0-2 miles and 2-5 miles to be statistically the same as at >5 miles. Table 3.2 summarizes the results of this analysis. 29 l a

Table ; 3.4 summarizes the result of this analysis. i 3.6 Deviations from the REMP l 3.6.1 Unavailable Samples t Deviations from the REMP associated'with missing TLDs- I resulted from theft of the dosimeters and were beyond the :
.. control of Waterford 3. Two TLDs were discovered missing
- from locations D-2 and F-9 during dosimeter change-out at :
the end of the-first quarter. Consequently,.the missing ! TLDs were replaced and the deviation recorded. j All scheduled air samples were available for analysis during . -{ the 1994 reporting period. However, eight air samples failed to meet the requirement for sample continuity. While ! two failures were due to a power failure at the sample ; locations and one failure was the result of equipment malfunction, the other five continuity failures were the '
. result of planned shut downs to. facilitate tubing and valve upgrades on the sample equipment. !

3.6.2 Missed Lower Limits of Detection All lower limit of detection requirements were met for 1994. 3.7 Annual Land Use Census In compliance with Waterford 3 ODCM, the annual land use census was conducted on October 12, 13, 14, and 20, 1994. The nearest residence, garden, and milking animal in each sector within a five mile radius of the plant were located by visual inspection and verbal inquiry. While residence locations remained unchanged for 1994, minor i 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. One new location for milk cows and several new locations for goats were identified as a result of this census; however, in all cases it was determined that the animals are not currently producing milk for human consumption. This information was ascertained by verbal inquiry with the owners of the animals.. Additionally, the ; cows previously located in Sector R at 4.9 miles from the plant have been removed. As a result of the interviews, Waterford 3 personnel obtained an agreement that the animal owners will se11 milk samples to Waterford 3 in the event of a radiological . emergency to provide additional data for analysis of environmental impact i i l 31

4.0 CONCLUSION
S ! The radiological environmental data collected during 1994 are consistent with the data obtained during the previous five years of plant operation (1989- : 93), the first two years of the REMP piior to Waterford 3 initial criticality , (1983-84), and the Pre-operational Environmental Radiological Surveillance (PERS) Program (1978-82). The only man-made radionuclides detected in the environmental samples analyzed during 1994 were cesium-137. and iodine-131. i
~
Cesium-137 was detected in two shoreline soil samples. Studies in Louisiana indicate that cesium-137 is commonly found in soils and sediments as a result , of fallout from nuclear weapons testing. In addition, the detected concentrations were consistent with 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. ' Analyses of milk samples indicated cesium-137 at +wo samples collected from the control location in June and July of 1994. The activity detected in both instances was at levels well below the required LLD and well below reporting levels defined in the Waterford 3 ODCM. In addition, cesium-137 concentrations detected in 1994 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 associated with the indicated concentrations are higher than would be expected with true activity and may be artifacts of counting statistics. In conclusion, based on the evaluation of the REMP data collected during 1994 ; the operation of Waterford 3 had no discernable radiological impact on the environment. ' G W 5 38
