1.0 INTRODUCTION

i 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 1996. 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 environmentalimpact of the plant. In order to conduct this evaluation, the data analyses and interpretations contained in this report fulfill the following specific objectives: to identify any radioactive materials or radiation in the environment associated with plant operation, 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 to verify compliance with federal regulatory requirements. e 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. 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 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 Lake 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 southeast), Oxychem Chemical Company (0.8 miles east southeast), and 1

i ] i Union Carbide, a chemical manufacturer (1.2 miles east southeast) are l [ operating in the area. i 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 L west northwest), Montz (1.0 miles north), Norco (2.5 miles east), Hahnville j (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 l 1 l 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 locations used during the pre-operational survey were incorporated into the operational program _. Further, the environmental data collected during i 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 fer implementing and ensuring that the REMP complies with federal regulatory,' Technical Specification, and i Offsite Dose Calculation Manua!(ODCM) requirements. Responsibilities of Waterford 3 personnelinclude 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. 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. In May of 1996, the primary contractor was replaced by the Environmental Services Laboratory located at the River Bend Nuclear Station. 2

Additionally, a separate contractor, the Fisheries Co-operative Extension Service of Louisiana State University, is responsible for the collection of fish samples. The Panasonic multi-e!ement thermoluminescent dosimeters (TLDs) were analyzed by theTLD Processing Laboratory at the ANO Nuclear Station. 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 and Attachments 6.13 & 6.14 of the Waterford 3 ODCM. Location maps of the sampling are illustrated in Figures 2.1 through 2.3. Any station deviations (i.e., unavailable samples and missed lower limits of detection) or changes made to the REMP during 1996 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. 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: an inner ring of stations, one in each of the sixteen meteorological sectors, in the general area of the site boundary; an outer ring of stations, one in ten of the sixteen e meteorological sectors, in the six to eight kilometer range from the site; and the balance placed in areas of specialinterest (e.g., population centers, schools, etc.) wlth one area serving as a control. The TLDs were exchanged quarterly by Waterford 3 personnel and were analyzed by the TLD Processing Laboratory at the ANO Nuclear Sts. tion. 3

. _ _.. ~. _. -. _. 4 N l' 2.3.2 Airborne Exposure Pathway Samples I Samples of airborne particulates and radiciodines were collected at i four indicator stations (APP-1, APQ-1, APG-1, APC-1) and one l control station (APE-30). Low-volume air pumps and flow totalizers l in weather proof shelters provided continuous air sampling. i Using the sampling device described above, airborne particulate samples were obtained on a filter and collected weekly by f 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 Drinking and surface water: i 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. 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. Groundwater: 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 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. 4

Shoreline sediment: Samples were obtained semi-annually from a sampling station at each side of the 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 Exposurs Pathway Samples Milk: Milk samples were collected semi-monthly from one indicator location (MKQ-5) and one control location (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 this location during 1996 (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: Fish samples were collected semi-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. Broad leaf vegetation: 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 location 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. 5

<s.. -u.. .aas a ~s e =.. = ex -,-- Food product: j 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. 4 2.4 Analytical Procedures by Entergy Services, Inc. (ESl): 2.4.1 Gross Beta Analysis in Air Particulates After allowing for the radon-222 and radon-220 daughter products to decay, the particu' ate 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 100-200 minutes or until the required LLD is achieved 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 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 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 ion electrode. 6

2.4.5 Gamma Spectroscopy Analysis Air particulate filters and iodine cartridges, water, milk, broadleaf vegetation, sediment, food products and fish samples are prepared in containers, using the apprcpriate geometry for its sampla 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. lodine analysis was performed using gamma spectroscopy. The time between sample receipt and analysis, the sample size and i count times were adjusted in order to attain the required lower limit of detection. 2.5 Analytical Procedures by Environmental Services Laboratory: 4 2.5.1 Sample Handling and Treatment 4 The laboratory staff receives and stores samples upon arrival. Environmental samples frequently require preparation prior to analysis, depending on media and analyses type. Water Samples Generally, field personnel acidify one-gallon water samples with concentrated hydrochloric acid when collected, unless otherwise directed by the analyticallaboratory. Tritium samples are not acidified and are stored in glass bottles under refrigeration until analysis can be performed. Air Filters t The laboratory handles air filters with care to avoid disturbing any deposition on the air particulate filter. They normally receive air filters in plastic petri dish containers that aid in transporting heavy dust loaded filters. 7

1 Milk The laboratory refrigerates milk samples until analyzed. They add a preservative (formaldehyde), if analyses are delayed for more than a few days, to inhibit bacterial growth and retard spoilage. Unless frozen or shipped on ice, milk samples analyzed for iodine-131 require addition of 100 milliliters of formaldehyde, of which field personnel normally add 10 milliliters prior to shipment, to avoid binding of the iodine that may occur with smaller levels of formaldehyde. Soil and Bottom Sediment The laboratory dries, grinds, and sieves soil and sediment samples before analysis. The lab then mixes the samples to ensure a homogeneous mixture. Other Samples i The laboratory preserves perishable samples by refrigeration or freezing. Vegetation and other samples may require drying, pulverizing or ashing before or after analysis for long-term storage. 2.5.2 Sample Analysis Gross Beta Air Sample Analysis The laboratory counts air filters for 100 minutes, or until required LLDs in ODCM Specification Table 6.12.1-3 are achieved, in a low-background alpha-beta counter, at least 24 hours after collection, to allow for the decay of short-lived isotopes, such as radon and thoron daughters. Gross Beta Water Sample Analysis This analysis measures overall beta radionuclides in water samples which involves evaporating a suitable aliquot of sample (usually 100 milliliters) in { a beaker then drying the beaker residue in a 47mm stainless steel j planchet under heat lamps or on a hot plate. The lab counts the l plancheted samples for 200 minutes, or until required LLDs in ODCM l Specification Table 5.8-3 ure achieved, in a low-background alpha-beta l counting system. The activity calculation includes a self-absorption attenuation factor (referred to as a salt density curve) for counter efficiency based on the weight of residue on each planchet. 8

i Tritium Water Sample Analysis l The laboratory typically adds six milliliters of water to 12 milliliters of liquid scintillation cocktail in a 20 milliliter vial, and then inserts the vial into a liquid scintillation spectrometer for a 200 minute count, or until required LLDs in ODCM Specification Table 5.8-3 are achieved. lodine-131 Sample Analysis The laboratory mixes four liters or more of the sample with a stable iodine carrier solution and tnen stirs the sample with an anion exchange resin to remove iodine from the sample. The resin is then transferred to a 250 milliliter micro-marinelli beaker and counted in a shielded intrinsic germanium detector until the required LLDs in ODCM Specification Table 5.8-3 are achieved. I Gamma Isotopic Sample Analysis . Milk and Water The laboratory fills a 3.7-liter marine!!i beaker with a representative aliquot of the sample and counts for a minimum of 60 minutes, or until i j required 1.LDs in ODCM Specification Table 5.8-3 are achieved, in a l shielded ;trinsic germanium detector coupled to a computer-based data acquisition system which performs a pulse height analysis. i 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 radionuclide identification and then performs a calculation using appropriate fractional gamma rey abundance, half life. detector efficiency anti net counts in the peak region. . Vegetation, Food and Garden Crops, and Fish The laboratory loads a maximum quantity of undried vegetation, food or garden crop sample into a tared 1-liter marinelli beaker and j weighs. The count is then sampled for 30 minutes, or until required LLDs in OOCM Specification Table 5.8-3 are achieved, in a shielded intrinsic germanium detector as described above. The laboratory loads as much as possible (up to the total sample) of the dried edible portion of a fish sample into a tared 0.5-liter marinelli beaker, or a lab-tech petri dish, depending on fish 9

l quantity, and weighs. The sample is then counted for a minimum of 30 minutes in a shielded intrinsic germanium detector as described above. . Soil and Sediment l The laboratory dries soil and sediment at a low temperature l (110-135'C) in a convection oven, then loads into a tared 1.0-liter marinelli beaker and weighs. They then count the sample for 30 minutes, or until required LLDs in ODCM Specification Table 5.8-3 are achieved, in a shielded intrinsic germanium detector as described above. 1 . Charcoal Cartridges The laboratory counts each charcoal cartridge separately, bypositioning each on the face of the detector in a converted one-half liter marinelli used as a holder. Each sample is counted for a minimum of 30 minutes or until LLDs in ODCM Specification Table 5.8-3 are achieved. . Air Particulate The laboratory stacks 13 air particulate filters, for a quarterly composite for each field station, one on top of another in a plastic petri dish and cover. The composite sample is counted for 30 minutes, or until required LLDs in ODCM Specification Table 5.8-3 are achieved, in a shielded intrinsic germanium detector as described above. 2.5.3 Data Reporting The laboratory calculates mean of analytical results as follows: T( = Xi / n where: Mean X = Xi = Individual sample results Number of sample results n = The lab rounds calculated values by inspection of digits to the right of third reported significant digit, with values less than 5 rounded down and values equal to or greater than 5 rounded up. 10

1 k The laboratory reports gross beta and tritium analytical results, less than a two sigma counting error, as less-than-LLD value for that sample. The Lab reports analytical results, greater than the two sigma counting j error, along with associated two sigma counting error, as a plus or minus (+) term. The laboratory considers calendar quarters and a quarterly composite j should consist of 13 weekly aliquots, or samples, such as air particulate i filters. s i 2.6 Environmental Dosimetry Model UD-814 Panasonic thermoluminescent dosimeters (TLDs) that i' contain one lithium borate and three calcium sulfate phosphor elements were used for environmental dosimetry. However, only the calcium j sulfate phosphor elements were used for analysis. For placement in field, i two annealed dosimeters are placed inside a plastic bag and mounted in an aluminum frame. The dosimeters are checked monthly and j exchanged for analysis each quarter using an automatic TLD reader j l manufactured by Panasonic (Model UD-710). 2.7 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 j 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 these lower limits of detection are i discussed in Section 3.6. t 2.8 Laboratory Quality Assurance i i i 2.8.1 Entergy Services, Inc.: i i i The Entergy Services, Inc. (ESl) System Chemistry Laboratory l responsibility for performing the radiological environmental sample i analyses was terminated in April of 1996. The ESI interlaboratory comparison program for the first quarter of 1996 is not available. ) i i F 11 i ,y

I ~ 2.8.2 EnvironmentalService Laboratory: During 1996, the Environmental Service Laboratory at River Bend Station participated in a Radiological Interlaboratory Comparison (cross-check) Program. This program satisfies the requirements of the Waterford 3 ODCM, Section 5.8.2, for participation in an 1 interlaboratory comparison program. The program involved i 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 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 1996 results of the laboratory's participation in the cross-check program. Investigation of Out of Control Limits Results (Explanation and Corrective Actions): Investigation was conducted by the Environmental Services Laboratory at the River Bend Station into the cross-check analysis results which were outside the control limits as defined in note "b" in Table 2.4. In the 1996 Cross-Check program, five sample analysis results (from total of ninety-nine sample results) were outside the controllimits. These five sample results are for the: . Second Quarter E0698-125 (Analytics) of 6/19/96 Cs-134 E0698-125 (Analytics) of 6/19/96 Ce-141 E0769-125 (Analytics) of 6/19/96 Cs-134 and . Fourth Quarter E0882-125 (Analytics) of 12/12/96 Cr-51 E0886-125 (Analytics) of 12/12/96 Fe-59 The E0769-125 sample was a duplicate sample of E0698-125. Also, E0886-125 sample was a duplicate sample of E0882-125. One sample was analyzed in the 3.7 liter geometry and the duplicate sample was analyzed in the 1.0 liter geometry. The duplicate samples were analyzed in the two geometry's to 12

validate the two geometry's used in analyzing water samples. Cs-134 results were out of control limits on both sample geometry analyses, while Ce-141, Cr-51 and Fe-59 were out of control limits only in one geometry analysis. As can be seen in Table 2.4, the average results for Cs-134 analyzed in the two geometry's are very consistent with each other. . Cs-134 (Gamma-in-Water Analysis) Sample No. E0698-125 (6/19/96) and Sample No. E0769-125 Duplicate (6/19/96) Review of the previous three years of cross-check data indicated that a low bias for Cs-134 existed due to cascade (coincidence) summing effect which is the simultaneous detection of two or more gamma rays originating from a single nuclear disintegration that results in only one observed (summed) pulse. The summing of pulses that are in true coincidence normally results in the removal of counts from the full-energy peak. When attempting to quantitatively measure radionuclides, that are subject to coincidence -summing (Cs-134), summing corrections may be necessary if deviations are expected to be greater than 10%. It was determined that Cs-134 analysis results have been bias low (11.5%) after reviewing cross-check results for the past three years. The abundances or yields of Cs-134 in the nuclide library were corrected by a factor of 0.895. The summing correction factor was applied to the Cs-134 yields in the software nuclide library for water. Reanalysis of the spectrum data with corrected yields produced results within the warning limits. Cs-134 results for 9/26/96 and 12/12/96 gamma-in-water studies were within the warning limits as defined in note "b" in the data table. . Ce-141 (Gamma-in-Water Analysis) Sample No. E0698-125 (6/19/96) The Ce-141 result for the 6/19/96 gamma-in-water sample E0698-125 was slightly outside (-3.05) the control limit. Review of the three analysis results did not indicate an outlier. The Ce-141 result of the duplicate 6/19/96 gamma-in-water sample E0769-125 was within control limits. Results for Ce-141 in all other gamma-in-water studies for 1996 were within the control limits. No reason was determined and no corrective actions were taken due to the single out of control limit result for Ce-141 in one sample of the second quarter study. 13

i e l . Cr-51 (Gamma-in-Water Analysis) Sample No. E0882-125 (12/12/96) The Cr-51 result for the 12/12/96 gamma-in-water sample d E0882-125 was outside (-3.59) the control limit. Review of the three results used for the average indicated an outlier result caused the low average. The percent coefficients of variation calculation will be used in the future as a criteria to determine l the presence of an outlier. Outlier results will be discarded, using just two results, or the sample will be analyzed a fourth 4 time, if necessary. j e Fe-59 (Gamma-in-Water Analysis) Sample No. E0886-125 (12/12/96) i The Fe-59 result for the 12/12/96 gamma-in-water (Duplicate) sample E0886-125 was outside (+3.66) the control limit. Review of the three results used for the average indicated an outlier I result caused the high average. The percent coefficients of variation calculation will be used in the future as a criteria to ' determine the presence of an outlier. Outlier results will be discarded, using just two results, or the sample will be analyzed { a fourth time, if necessary. impact Statement: 4 ' There is no impact on past data indicated by these cross-check program exceptions. Environmental samples are analyzed and reported with a 95% confidence level that the analytical result with its associated error encompasses the "true" value.

l 3.0 DISCUSSION OF RESULTS Analytical results for the year 1996 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. l 3.1 Direct Radiation Exposure Pathway i The average exposure rates measured by thermoluminscent dosimeters (TLDs) at both control and indicator stations were 14,12,17, and 15 mrem / standard quarter for the first, second, third, and fourth quarters of 1996, respectively. The average exposure rate of the 120 indicator TLD locations was 14 mrem / standard quarter compared to 14 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 quarter) and 21 mrem / standard quarter (H-6,1st quarter) for all locations. Table 3.1 compares the indicator TLD results by directional sector and I distance from the facility. A comparison of directional sectors indicates that the highest average exposure rate in 1996 was 16 mrem / standard quarter in Sector N (compass direction W). j The average exposure rates during 1996 are consistent with those from i the pre-operational program and the previous years of operation (Figure { 3.1). In particular, the pre-operational survey indcates that exposure j rates ranged between 11 and 33 mrem / standard quarter with an average j of 20 mrem / standard quarter. Similarly, the range indicated during the ) previous years of operation was from 7 to 23 mrem / standard quarter with an average exposure rate of 14 mrem / standard quarter. 3.2 Airborne Exposure Pathway 3.2.1 Airbome Particulates Gross beta activity ranged from 0.003 pCi/m (APP-1,3/11-3/18) to 0.051 j pCi/m (APG-1,6/3-6/10) with an average of 0.018 pCi/m for 264 j 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/m i 3 as compared to 0.019 pCi/m at the control (APE-30) location. The airborne gross beta activity results obtained during 1996 are i consistent with the results from the pre-operational program and the previous years of operation (Figure 3.2). In the period from 1984 to i 1995, the average yearly gross beta activity for the indicator i locations ranged from 0.014 to 0.027 gCi/m with an average of 0.019 pCi/m compared to 0.020 pCi/m at the control location. Also, pre-operational survey indicates that in periods not significantly 30

influenced by nuclear weapons testing, the gross beta activity ranged between 0.007 and 0.480 pCi/m with an average of 0.080 pCi/m. 3.2.2 Airbornelodine All of the 264 airborne iodine-131 results were below the calculated { lower limit of detection (LLD) which varied from 0.013 to 0.048 3 pCi/m and were below the required LLD (0.7 pCi/m ) required by the Waterford 3 ODCM. The sample LLD variability 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. 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 analyzed by gamma spectroscopy for iodine-131 (Table B-4). All of the 78 composite sample iodine-131 results were below the calculated lower limit of detection (LLD). Gross beta activity was detected in thirty-four of the thiry-nine composites with a range of 2.1 (DWE-5,2/21-3/18) to 11.6 (DWG-2,7/22-8/19) pCi/l and an average activity of 5.3 pCi/l. The average activity for the control location, DWP-7, was 4.5 pCi/l compared to the averages of 6.1 and 4.4 pCi/l for indicator stations DWG-2 and DWE-5, respectively. Analyses for gross beta in drinking / surface water were not performed during the pre-operational survey. However, in order to fulfill comparison requirements,1996 data will be compared to data from the 1983 report and the previous years of operation. The gross beta activity results obtained during 1996 are consistent with those from the 1983 reporting period and the previous years of 31

operation (Figure 3.3). In particular, the period from 1984 to 1995, average gross beta activity per year for the indicator locations ranged from 3.8 to 10.0 pCi/l with an average of 5.4 pCi/l i compared to 4.9 pCi/l at the controllocation. Similarly, the 1983 survey indicates that in periods not significantly influenced by _ nuclear weapons testing the gross beta activity ranged between 2.9 l and 14.0 pCi/l with an average of 7.0 pCi/l. Forty-five composite drinking / surface water samples were analyzed by gamma spectroscopy. Results indicate that all measurements were below the calculated LLDs, except one sample ( Cs-137 in DWG-2 3/18-4/1). However, the level of Cesium-137 in this indicator sample (2 +/- 1 pCi/l) is below the LLD level (18 pCl/l) ^ required by the Waterford 3 ODCM and has an associated very high level of statistical uncertainty. Tritium analysis of drinking / surface water samples indicate that nine of the twelve measurements were below the calculated LLD. Tritium was detected in two samples from the indicator location DWG-2 (139+/-107pCi/l,4/1-6/24 and 185+/-110 pCi/l,9/30 -12/23) and in one control sample DWP-7 (127+/-106 pCi/l,4/1-6/24). The detected activities in these three samples were considerably below the LLD (2000 pCL iter) required by the Waterford 3 ODCM and has a very high level c: statistical uncertainty associated with them. The tritium concentrations detected in _1996 are consistent with those from the pre-operational program and the previous' years of j operation. In particular, the pre-operational survey indicates that l tritium concentrations in drinking water samples ranged between 1 70 and 180 pCi/l with an average of 116 pCl/l Similarly, the range indicated in the previous years of operation was from 170 to 545 pCill. 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 analyses indicate that all measurements were below the calculated LLDs. Tritium was detected in three of the four groundwater samples. The detected tritium activities in i these three samples ranged between 392 and 1015 pCi/l with an average activity of 686 pCi/l and were below than the LLD (2000 pCi/ liter) required by the Waterford 3 ODCM. The tritium concentrations detected in 1996 are consistent with i those from the pre-operational program and the previous years of operation, in particular, the pre-operational survey indicates that tritium concentrations in ground water samples ranged between 50 32 N

U and 180 pCl/l with an average of 121 pCill. Similarly, the range indicated in the previous years of operation was from 249 to 650 pCi/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). Cesium-137, a man-made nuclide was detected in one sample from station SHWK-1 at a concentration of 71 +/- 24 pCi/kg (dry) which is less than the required LLD (180 pCi/kg dry). No other man-made radionuclides were detected in any of the samples. The cesium-137 results obtained during 1996 are consistent with those from the pre-operational program and the previous 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 averago concentration of 164 pCi/kg (dry). Similarly, the range indicated during the previous years of operation was from 18 to 142 pCi/kg (dry) with an average activity of 52 pCi/kg (dry). Further studies in Louisiana indicate that cesium-137 is commonly found in soil and sediment as a result of atmospheric weapon testing. Because the cesium-137 levels are consistent with pre-operational values, the cesium-137 level detected in 1996 is more than likely attributable to weapon testing fallout. 33

i 3.4 Ingestion Exposure Pathway 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. Results from iodine-131 analyses indicate that all measurements were below the calculated LLD. Further, cesium-137 was detected in two control samples (MKQ-45,4/1 and 4/15) at concentrations of 2.0 +/- 1.0 pCi/l. However, the levels of cesium-137 in these control samples are below the LLD level ( 18 pCill) required by the Waterford 3 ODCM and have a very high level of statistical uncertainty associated with j I them. 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. No man-made raaronuclides were detected above their lower limits of detection in any samples. 3.4.3 BroadLeaf Vegetation Thirty-six broad leaf vegetation samples were collected and analyzed by gamma spectroscopy and a radiochemical procedure for iodine-131. No man-made radionuclides were detected in any of the collected samples 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. No man-made radionulides were detected in the collected samples above their calculated LLDs. 34

l 3.5 Statistical Analyses 3.5.1 Calculation of the Mean and Standard Deviation The mean and standard deviation for different groups of analyses are calculated using the following equations: X= f E and /n TU [ (Xi - E)' S= (n - 1) r where: ~X = mean of sample population, S = standard deviation of sample population, n = number of samples in sample population, and 2 i X;= value of the i'th sample. 3.5.2 Comparing Two Sample Population Means The mean 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 botn populations are equal. The "t" value can be calculated from the equation below (obtained from the CRC Standard Mathematical Tables,26th Edition (1981)): X-t= 'k-1M+h,-1['1_ _ + _ _ ' " j n, + n, - 2 < n, n,, s 35

l where: I t = calculated "t" value, X = mean of first data set, Y = mean of second data set, y, = number of variables in first data set, S x = standard deviation of first data set, = number of variables in second data set, and y y S = standard deviation of second data set. y 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 x second population (m ) assuming that the true standard deviations y of both populations are equal (m = m ). The calculated "t" value i x y is compared to a tabular "t" value such that:

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

x y

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

l

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

x 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 -2. Tabular values of the "t" were obtained from x y the CRC Standard Mathematical Tables,26th Edition (1981). 1 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 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 that the average exposure rates at 0-2 miles and 2-5 miles are statistically the same as the rates at >5 miles. Tuble J.2 summarizes the results of this analysis. 36

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 detected at the control station. Table 3.3 summarizes the results of this analysis. 3.5.5 Gross Beta Activity in Monthly Drinking Water Camposites Finally, the 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 activit/ 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 One sample was missed during the 1996 reporting period (APC-1 1/8-1/15). The air sample was unavailable as a result of air sample pump failures and is summarizd on Table 3.5. Milk samples were not available during 1996 from the animal owners at rt6 tion MKO-1 since the cows are not currently producing milk for human consumption. With the absence of milk samples at these stations, broad leaf vegetation sampling was performed. 3.6.2 Lack of Sample Continuity One air sample and one water sample failed to meet the requirement for sample continuity as explained in Table 3.5. 3.6.3 Missed Lower Limits of Detection All lower limit of detection requirements were met for 1996. 37

3.7 Annual Land Use Census In compliance with the Wateriord 3 ODOM, the annual land use census 1 was conducted on October 2 and 3,1996. _The nearest residence, garden, and milking animalin each sector within a five mile radius of the j plant were located by visual inspection and verbal inquiry. While locations remained unchanged for 1996, minor changes in food product locations were observed as recorded on Table 3.6. Additionally, I large tracts of sugar cane are still being cultivated near the plant and remain classified as food products. One location for milk cows (in Sector E) have been removed. Three new locations for goats and three new locations for beef cows were identified; l however, in all cases it was determined that the milk 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 environmental impact. l 3.8 Sampling Schedule Change: Based on Waterford 3 operational historical data, the REMP sample frequency schedule was revised below what is defined in the NRC Branch Technical Position, Revision 1, November 1979 as documented in Radiation Protection calculation file # HP-CALC-96-005. Also, fooa product sample was deleted based on the historical data and the fact that i no areas surrounding the plant are irrigated with water in which plant i wastes are discharged. The revised sampling schedule is presented in Table 3.7. This change has been covered in the Offsite Dose Calculation Manual (ODCM) and the Technical Requirements Manual (TRM). However, no change was implemented to the REMP sample collection l schedule during this reporting year. 4 i J 4 6 38

4.0 CONCLUSION

S The radiological environmental data collected during 1996 are consistent with the data obtained during the previous years of plant operation (1985-94), 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 1996 was cesium-137. Cesium-137 was detected in one surface / drinking water sample. The detected concentration was consistent with pre-operational levels and the levels detected in the previous years of operation. Further, the concentration detected was lower than the required LLD and well below levels requiring notification. In addition, statistical errors associated with the indicated concentration is higher than would be expected with true activity and may be artifacts of counting statistics. Cesium-137 was also detected in one shoreline soil sample. Studies in Louisiana i indicate that cesium-137 is commonly found in soil and sediment as a result of fallout from nuclear weapons testing. In addition, the detected concentration was consistent with pre-operational levels and the levels detected in the previous years of operation. Further, the concentration detected was lower than the required LLD and well belov levels requiring notification. Analyses of milk samples indicated cesium-137 in two samples collected from the i controllocation during April of 1996. The activity detected in both instances was at levels considerably below the required LLD and well below reporting levels defined in the Waterford 3 ODCM. Further, statistical errors associated with the indicated concentrations are higher than would be expected with true activity and may be artifacts of counting statistics. Tritium was detected in surface / drinking water samples (two indicator samples and one control sample). Tritium was also detected in three ground water samples. The detected activities in these samples were below the LLD required by the Waterford 3 ODCM and have a very high level of statistical uncertainty associated with them. The tritium concentrations detected in 1996 are consistent with those from the pre-operational program and the previous years of operation. in conclusion, based on the evaluation of the REMP data collected during 1996, the operation of Waterford 3 had no discernable radiological impact on the environment. 49
