AliNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT FOR THE LOUISIANA POWER & LIGHT WATERFORD STEAM ELECTRIC STATION, UNIT 3 JANUARY 1 THROUGH DECEMBER 31, 1987 Docket Number: 50-382 License Number: NPF-38 88050?.01S0 871231 PDR ttDOCK 0500038' I R DCD I W390370SA

l ABSTRACT This report is issued pursuant to Waterford 3 SES Technical Specification 6.9.1.7. Its purpose is to discuss the Waterford 3 SES Radiological ;

Environmental Monitoring Program (REMP), present the results of the program for the year of 1987, and to evaluate the radiological impact on the 1 environment resulting from plant operation.

The Waterford 3 SES REMP collected data on environmental radioactivity levels around the Waterford 3 SES 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 SES exhibited no discernable impact on the levels of radioactivity in the environment during 1987.

1.0 INTRODUCTION

This report describes the Radiological Environmental Monitoring Program (REMP) for the Waterford 3 Steam Electric Station (SES) nuclear power plant and discusses the results obtained during the calendar year 1987.

The results discussed within this report were used to evaluate the radiological environmental impact resulting from the operation of Waterford 3 SES. The submission of this report to the Nuclear Regulatory Commission fulfills the requirements pursuant to Waterford 3 SES Technical Specification 6.9.1.7.

1.1 Program and Report Objectives The overall objective of the monitoring program was to evaluate the radiological environmental impact of the plant. The evaluation included an assessment of actual or potential exposures of humans to radioactive materials or radiation resulting from plant operation. In order to conduct this evaluation, the data analyses and interpretations contained in this raport fulfilled the following specific objectives:

a. identify if any radioactive materials or radiation in the environment was associated with plant operations

b. compare the results obtained during the reporting period with past operational and preoperational data, when appropriate, to identify any trends or accumulation of radioactivity in the environment;

c. estimate the maximum expostte to a member of the general public from any environmental data wh;ch indicates the presence of plant related radioactivity

, and

d. verify compliance, when appropriate, with relevant federal requirements.

1.2 Plant and Site Description The Louisiana Pos er & Light Company, Waterford Steam Electric Station, Unit No. 3 employs a pressurized water reactor for the production of approximately 1153 gross (1104 net) megawatts of electricity. The station uses a once through flow of water obtained from and discharged to the Mississippi River for condenser cooling, on March 4, 1985, the unit achieved initial criticality.

Waterford 3 SES is located on the west bank of the Mississippi River at River Hile 129.6 between Baton Rouge and New Orleans, Louisiana. The site is in the northwestern section of St. Charles Parish approxime.tely 3 miles southeast of the St. John the Baptist Parish boundary near the towns of K111ona and Taft. The Mississippi River is the closest prominent natural feature while others include Lac des A11 emends, 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 dry land between the Mississippi River and the wetlands. Near the Waterford SES site are several large industrial facilities, including Waterford 1 and 2 Steam Electric Stations (0.4 miles northwest of the site). Little Gypsy Steam Electric Station (0.8 miles northeast of the site, across the river from Waterford 3 SES), Beker Industries, a fertilizer manufacturer (0.6 miles east southeast). Occidental Chemical Company (0.8 miles east southeast),

and Union Carbide, a chemical manufacturer (1.2 miles east southeast). Louisiana Power & Light Company owns and operates the above mentioned steam electric stations.

Major urban centers in the region of the site include New Orleans (approximately 25 miles east of the site) and Baton Rouge (approximately 50 miles west northwest). Communities in St.

Charles Parish near the site include K111ona (0.9 miles west northwest), Montz (1.0 miles north), Norco (1.9 miles east),

2.0 PROGRAM DESCRIPTION !

A general summary of the REMP is given in Table 2.1. Brief descriptions of the sampling stations and their locations are given in Table 2.2. The ,

locations of the sampling stations with respect to the Waterford 3 SES ;

site are illustrated in Figures 2.1 through 2.3. A more detailed l

] description of the overall REMP is discussed in the following chapter.

1 2.1 History and Development

.; The Waterford 3 SES REMP was initiated in April of 1983. The program evolved from the Preoperational Environmental Radiological 4

Surveillance (PERS) program which was conducted from 1978 through 1982. The equipment, procedures, techniques, and many of the same j sampling locations used during the preoperational survey were ;

incorporated into the operational program. The environmental data i collected during the first two years of the REMP (1983 and 1984),

when Waterford 3 SES had not yet achieved initial criticality,

were used to supplement the baseline data obtained during the PERS Program.

LP&L personnel were responsible for the proper implementation of I the REMP and insuring that the program complied with federal regulatory requirements and Technical Specification requirements.

. Specific responsibilities of LP&L personnel included collecting i 1

(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 Monitoring :

Report as well as any other relevant report to the Nuclear Regulatory Commission. l 1

The primary contractor, the Technical Services Department of ,.

i Arkansas Power & Light (AP&L) located in Little Rock Arkansas. [

l was responsible for performing radiological analyses; conducting ,

the initial data review; preparing monthly and annual results reports; and overseeing laboratory quality assurance and control.

d A separate contractor, the Fisheries Co-operative Extension Service of Louisiana State University, was responsible for the collection, and delivery to LP&L, of fish samples.

2.2 Sample Collection and Handling Procedures f The types of samples collected, the analyses performed, the sample collection frequencies, and the location of the sampling stations are summarized in Tables 2.1 and 2.2. The information contained in these tables is based on the requirements specified in Table 3.12-1 of Waterford 3 SES Technical Specification 3.12.1. The locations of the sampling stations with respect to the Waterford 3 SES site !

are illustrated in Figures 2.1 through 2.3. Any deviations from the REMP (i.e., unavailable samples and missed lower limits of 3

detection) observed during 1987 are discussed in Section 3.5.

Changes made to the REMP during 1987 as a result of the annual land use census are also discussed in Section 3.5.

The environmental samples collected were classified into four general categories according to exposure pathways: direct radiation, airborne, waterborne, and ingestion. The collection and handling procedures used to obtain these samples are described in the following sections. The descriptions are intended to provide a concise overview of what was done rather than to be step-by-step procedures.

2.2.1 Direct Radiation Exposure Par.hway Samples Integrated external gamma exposures were determined using thermoluminescent dosimeters (TLDs). Multi-element TLDs manufactured by Panasonic were placed 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 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 LP&L personnel.

2.2.2 Airborne Exposure Pathway Samples Samples of airborne particulates and radiciodines were collected at five locations. The locations included four indicator stations (APP-1, APQ-1, APG-1. APC-1) and one control station (APE-30). The samples were collected using low-volume air sampling devices. The devices were designed to sample air on a continuous basis and record the volume of air sampled. The pump and metering device were housed inside a weatherproof shelter.

Airborne particulate samples were obtained by passing air through a particulate filter using the device described above. The filters were collected weekly by LP&L personnel and sent to the contract laboratory for gross beta analysis. These filters were composited by the contract laboratory on a quarterly basis for isotopic analysis by gamma spectroscopy.

Airborne iodine sampling was done in conjunction with air particulate sampling. After the air passed through the particulate filter, it passed through a charcoal cartridge to collect airborne iodine. The cartridges were collected weekly by LP&L personnel and sent to the contract laboratory for iodine-131 analysis by gamma spectroscopy.

2.2.3 Waterborne Exposure Pathway Samples The Mississippi River is the major source of drinking water in the vicinity of Waterford 3 SES and it is also the surface water into which the plant discharges.

Therefore, water samples taken from the Mississippi River were designated as both drinking water and surface water samples.

Composite drinking / surface water samples were obtained from the Mississippi River using automatic composite samplers placed at one upstream (DWP-7/SWP-7) and at two downstream (DWG-2/SWG-2, DWE-5/$WE-5) locations from the plant. These composite water samples were collected biweekly by LP&L personnel. LP&L personnel acidified the samples with hydrochloric acid prior to shipment to the contract laboratory. The contract laboratory analyzed the biweekly samples for iodine-131. The biweekly samples were composited on a monthly basis by the contract laboratorf for gross beta and gamma spectroscopy analyses. The samples were also composited on a quarterly basis for tritium analysis.

Due to the high water table resulting from shallow aquifers in the vicinity of the site, groundwater discharge could be sampled from a drainage canal. Groundwater samples were obtained quarterly by LP&L personnel from one sampling location (GWJ-1) using a grab sampling technique. The samples were acidified with hydrochloric

! acid prior to shipment to the contract laboratory for tritium and gamma spectroscopy analyses.

Shoreline sediuent samples were obtained semi-annually by LP&L personnel from two sampling stations. One station was located on the shoreline of the Mississippi River (SRWE-3) and the other was located on the shoreline of the 40-Arpent canal (SHJW-1). The samples collected were shipped to the contract laboratory without further processing.

2.2.4 Ingestion Exposure Pathway Samples Milk samples were collected semi-monthly by LP&L personnel. Control samples were obtained through Louisiana Nuclear Energy Division personnel from the control station (MKQ-45) located in Denham Springs, Louisiana. Indicator samples were collected locally from one station (MKQ-5). Although two additional indicator locations were identified (MKQ-1 and MKE-4), no samplas were available from these locations during 1987 (see Section 3.5). All samples had formaldehyde added prior to shipment to the contract laboratory for iodine-131 and gamma spectroscopy analyses.

Fish samples were collected bi-annually upstream (FH-1) and downstream (FH-2) from the plant by a contractor. The fish were obtained by netting. The contractor segregated the samples by species and location sampled prior to delivery to LP&L. The samples were shipped frozen to the contract laboratory for analysis by gamma spectroscopy.

LP&L personnel collected broad leaf vegetation samples monthly by obtaining cuttings taken at least one inch above the ground. Samples were collected from two indicator locations (BLB-1, BLQ-1) and from one control location (BLK-15). The samples were shipped to the contract laboratory without further processing.

A food / garden crop sample (sugarcane) was collected at the time of harvest by LP&L personnel, from one location (FPP-2). The sample was collected by normal harvesting techniques at the time of harvest. This sample was taken in place of that from indicator location FPP-1 since no samples were available from this location during 1987 (see Section 3.5). The sample was sent to the contract laboratory without further processing for iodine-131 and gamma spectroscopy analyses.

2.3 Analytical Procedures Brief synopses of the analytical procedures used by AP&L and LP&L are given in Appendix E. These synopses are intendeel to provide an overview of what was done rather than to be stop-by-step procedures.

6 W390370SA

l The minimum sensitivities for the analytical procedures used in the REMP are reflected by the Lower Limits of Detection (LLD) values presented in Table 2.3. These valu6s are the same as the ones given in Table 4.12-1 of Watertord 3 SES Technical Specification 4.12.1. The LLD's are a prior,i estimates based on assumed sample volumes, counting times, detector efficiencies, etc. These values reflect the lower levels of detection that were to be attained for the majority of the analyses performed.

All analyses that could not achieve these lower limits of detection p.re discussed in Section 3.5.

2.4 Laboratory Quality Assurance During 1987 AP&L performed a variety of quality assurance analyses. Spiked and blank samples prepared in-house and Environmental Protection Agency (EPA) reference samples were analyzed. It was estimated that between 5% and 10% of all analyses were for quality assurance purposes.

AP&L also participated in the EPA radiological interlaboratory comparison (cross-check) program. Participation in this program involved a number of analyses on various sample media typically found in REN!'s. As a result of participation in the program, an objective measure of analytical precision, accuracy, and an estimation of bias were obtained. In the event that any results obtained by AP&L were not within control limits, as specified by the EPA, an investigation was conducted to determine the cause and corrective action was taken to prevent a recurrence. Appendix D lists the 1987 results of AP&L's participation in the cross-check program.

3.0 DISCUSSION OF RESULTS Analytical results for the year 1987 are discussed in this section by exposure pathway, type of sample, and analysis performed. The analytical results of the REMP are summarized in Appendix A and data for the individual analyses are presented in the tables of Appendix B. All of the results discussed in this section and summarized in the appendices of this report focus mainly on man-made radioactivity.

3.1 Direct Radiation Exposure Pathway The average dose rates measured at all stations by both control and indicator Thermoluminscent Dosimeters (TLDs) were 14, 14, 14, and 14 mrem per standard quarter (90 days) for the first, second, third, and fourth quarters of 1987, respectively. The average of 115 indicator location TLD exposures was 14 mrem / standard quarter compared to 18 mrem / standard quarter for the average of four exposures at the control location. The lowest and highest individual exposures were 8 mrem / standard quarter (C-1, 4th quarter; M-1 second quarter) and 19 mrem / standard quarter (E-30, 1st quarter) for all locations.

Table 3.1 compares the TLD results by direction and distance from the facility. Of the 16 indicator sectors, Sector Q demonstrated the highest average of 16 mrem / standard quarter; however, this average exposure is less than the control's of 18 mrem / standard quarter. The average exposure rate from TLD's located within two miles from the plant was statistically identical to the average exposure from stations located more than five miles from the plant using the standard "t" test (see Appendix F). The average exposure rate from TLD's located between two and five miles from the plant was statistically the same as the average exposure rate from stations located within two miles of the plant. Therefore, Waterford 3 SES operation did not have a detectable impact on '

direct radiation exposures from gamma radiation.

3.2 Airborne Exposure Pathway 3.2.1 Airborne Particulates Gross beta activity ranged from 0.007 pCi/ cubic meter (APE-30, 6/29-7/06) to 0.043 pCi/ cubic meter (AFG-1, 3/09-3/16) with an average of 0.021 pCi/ cubic meter for 258 measurements from all five sampling locations. The average gross beta activity for the control location, APE-30, was 0.021 pCi/ cubic meter compared to 0.020 pCi/ cubic meter for the four indicator locations (APP-1, APQ-1, APG-1, APC-1).

The control station average is statistically the same as the average from each indicator station using the standard statistical "t" test (see Appendix F).

22 6390370SA

l i

i The gross beta activity results obtained during 1987 are consistent with those from 1986, 1985 and the preoperational program. During the preoperational sursey, in periods not significantly influenced by nuclear weapons detonations, the gross beta activity ranged between 0.02 and 0.04 pCi/ cubic meter. During the first two years of the REMP prior to Waterford 3 SES operction, the average gross beta activity for a11' stations was 0.021 pCi/ cubic meter with a range of 0.006 to 0.! pCi/ cubic meter.

During 1985 the average gross beta activity for the control location was 0.022 pCi/ cubic meter compared to 0.021 pCi/ cubic meter for the four indicator locations.

In 1986, during periods not influenced by the Chernobyl incident, the average weekly gross beta activities from the control and indicator stations were 0.020 and 0.021 pCi/eubic meter, respectively.

3.2.2 Airborne Iodine All of the 258 airborne iodine-131 results were below the lower limits of detection which ranged from 0.005 to 0.012 pCi/ cubic meter. The variabilit; of the lower limit of detection was due primarily to the difference between air sample volumes.

3.2.3 Gamma Isotopic Analysis Gamma spectroscopy results indicated detectable levels of cosmogenically produced bery111um-7 and naturally occurring potasium-40 in the twenty quarterly composites. No man-made radionuclides were detected above their respectivo lower limits of detection.

3.3 Waterborne Exposure Pathway 3.3.1 Drinking / Surface Water As mentioned previously, drinking water is considered synonymous with surface water. Results obtained from samples collected and analyzed as drinking water can be designated "surface water results". Therefore, the results of the monthly and quarterly gamma spectral analyses as well as the quarterly tritium analysis reported as drinking water results are the same as for those reported as surface water results.

Eighty-one composite drinking / surface water samples were analyzed by a radiochemical procedure for iodine-131. All indicator measurements were below the lower limits of detection however 2 of the control measurements indicated -

iodine at an average level of 0.6 pCi/1. The samples were composited on a monthly basis and analyzed by gamma spectroscopy. Only naturally occurring potassium-40 was detected. No man-made gamma emitters were detected above their respective lower limits of detection.

23 W390370SA

1 l

The monthly composites were analyzed for gross beta activity. Gross beta activity was detected in thirty-one of the forty-two composites with an average-activity of 6.1 pCi/ liter. The average activity for the control location was 5.1 pCi/ liter, compared to the averages of 8.2 and 4.2 pCi/ liter for indicator stations DWG-2 and DWE-5, respectively.

The average gross beta activity detected at indicator station DWG-2 is statistically the same as that of the control station DWP-7 using the standard "t" test (see Appendix F). The average gross beta activity at station DWE-5, five miles downstream, is also statistically the same as the control station average using the standard "t" test.

Drinking / surface water samples were also composited quarterly and analyzed for tritium. All measurements were below the respective lower limits of detection.

Although not required in the REMP the filters obtained from the gross beta analysis were composited monthly and analyzed by gamma spectroscopy. No man-made gamma emitters were detected above their respective lower limits of detection.

3.3.2 Groundwater Four groundwater samples were collected from one sampling location, GWJ-1, and analyzed for tritium and gamma ray emitters. Tritium was detected in one of the four samples at a concentration of 249 pCi/1 2211. Tritium is naturally occurring and during the preoperational program, tritium was frequently detected in groundwater samples at concentrations ranging between 50 and 180 pCi/1. Although the detected concentration is higher than these values, the detected concentration has a high degree on uncertainty associated with it. This value is also below the usual lower limit of detection. However, conservatively assuming that all of the tricium activity detected in the groundwater at station GWJ-1 originated from the plant, the maximum dose to a member of the general public was calculated. The methodology and assumptions used to calculate the maximum dose were based on the guidance provided in Regulatory Guide 1.109 (10/77). The dose to the maximum exposed individual, a child, was calculated by the following equation:

(1) R = (C) (U) (D) where R is the annual dose to any organ or the total body in mrem /yr; 24 W390370SA

C is the radionuclide concentration in the groundwater sample in pC1/1; U is the amount of water which is ingested, assuming that this groundwater is ingested without treatment, in 1/yr, given in Table E-5 of Regulatory Guide 1.109; 510 liters for a child; and D is the internal dose conversion factor for ingesting contaminated water given in Table E-13 of Regulatory Guide 1.109; the values for tritium for each organ or the whole body are identical and this value is 2.03E-7 mrem /pCi ingested.

Using equation (1), the maximum annual dose to a child drinking 510 liters of untreated groundwater was calculated to be 0.026 mrem /yr to any organ or to the total body. Therefore, any radiological impacts to the general public are inconsequential.

3.3.3 Shoreline Sediment Four shoreline soil samples were collected from two 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 into which turbine building sumps are discharged (SHWJ-1).

Naturally occurring potassium-40, radium-226, actinium-228, and other naturally occurring radioisotopes were detected in all of the samples. Man-made radioactivity, cesium-137, was detected in the sample obtained from station SEWJ-1 at a concentration of 21 pCi/kg(dry). No other man-made radionuclides were detected in any of the samples.

Radioactive release permits for the year 1987 show that no cesium-137 was discharged into the drainage canal from which the sample came. Therefore, the presence of the cesium-137 is most likely attributable to fallout from past nuclear weapons detonations or the Chernobyl incident.

This assumption is consistent with observations made during the preoperational survey for soil samples collected from the shoreline of the Mississippi River. During the preoperational program, cesium-137 was detected in 13 of 18 soil samples at concentrations ranging between 30 and 890 pCi/kg(dry) with an average concentration of 138 pCi/kg(dry). In 1985 and 1986 cesium-137 was detected at this site at levels of 99 and 65 pCi/kg (dry),

respectively, establishing a downward trend in activity.

25 W390370SA

However, conservatively assuming that all of the cesium-137 activity detected in the shoreline sediment at station SHWJ-1 originated from the plant, the maximum dose to a member of the general public was calculated. The methodology and assumptions used to calculate the maximum dose were based on the guidance provided in Regulatory Guide 1.109 (10/77). The dose to the maximum exposed individual, a teenager, was calculated by the following equation:

(2) R = (40) (C) (U) (D) where:

R is the annual dose to the skin or the total body in mrem / year; 40 is the area-mass conversion factor given in Appendix A of Regulatory Guide 1.109 in kg/ square meter; C is the radionuclide concentration in the shoreline soil sample in pct /kg; U is the maximum exposure time given in Table E-5 of Regulatory Guide 1.109; 67 hours7.75463e-4 days 0.0186 hours 1.107804e-4 weeks 2.54935e-5 months for a teenager; and D is the external dose conversion factor for standing on contaminated ground given in Table E-6 of Regulatory Guide 1.109; the values for skin and total body are 4.9E-09 and 4.2E-09 mrem /hr per pCi/ square meter, respectively.

Using equation (2), the maximum annual dose to a teenager spending 67 hours7.75463e-4 days 0.0186 hours 1.107804e-4 weeks 2.54935e-5 months at the shoreline of the canal was calculated to be approximately 0.003 mrea/yr to the skin and to the total body. Therefore, any radiological impacts to the general public resulting from cesium-137 detected in the shoreline soil are infinitesimal.

3.4 Ingestion Exposure Pathway 3.4.1 Milk Forty-nine milk samples were collected from two sampling locations and analyzed by a radiochemical procedure for iodine-131. All indicator station measurements were below the lower limits of detection; however, iodine was detected at the control station at a concentration of 0.2 pCi/1. The samples were also analyzed by gamma spectroscopy. Naturally occurring potassium-40 was detected in all samples. Cesium-137 was detected in two of the control samples from KKQ-45 at an average concentration of 4.5 pCi/L. This man-made activity is most likely attributable to fallout. All man-made gamma emitters were below their respective lower limits of detection.

26 W390370SA

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 all samples.

3.4.3 Broad Leaf Vegetation Waterford 3 SES Technical Specification 3.12.1 requires broad leaf vegetation to be sampled in the event milk samples are unavailable. Since milk samples could be collected reliably from only one sampling location within five miles of Waterford 3 SES, broad leaf vegetation was sampled monthly at two indicator locations. Broad .'.eaf vegetation was also collected from one control location.

Thirty-three broad leaf vegetation samples were collected and analyzed by a radiochemical procedure for iodine-131.

All measurements were below the lower limits of detection. The samples were also analyzed by gamma spectroscopy. Naturally occurring radionuclides were detected in all of the samples, however no man-made radionuclides were detected above their lower limits of detection.

3.4.4 Food / Garden Crops One food / garden crop sample was collected and analyzed by a radiochemical procedure for iodine-131. Iodine-131 concentration was below the lower 41mit of detection. The sample was also analayzed by gamma spectroscopy. Naturally occurring potassium-40, radium-226, and te11urium-208 were the only radionuclides detected. All man-made gamma emitters were below their respective lower limits of detection.

3.5 Deviation from the REMP 3.5.1 Unavailable Samples During 1987 deviations from the REMP sampling schedule occurred. All of the deviations (with the exception of those associated with TLDs and the April broadleaf sample) were either the result of equipment malfunctions or *he result of natural events beyond the control of LP&L. With respect to equipment malfunctions, the causes leading to the malfunction were identified and maintenance or replacement performed to prevent recurrence of the event.

Deviations from the REMP associated with TLDs were beyond the control of LP&L and resulted from theft of a few of the dosimeters placed in the field. When a dosimeter was 27 W390370SA

l i

discovered missing during a monthly inspection, the TLD was replaced and the deviation noted. A listing of all unavailable samples for 1987 along with associated explanations of why the samples were not collected is given in Appendix C. . A more detailed explanation for milk and vegetation sample unavailability is discussed below.

Milk samples were not available during 1987 from the animal owners at station MKE-4 and MKQ-1 since neither the goats at MKE-4 nor the cows at MKE-1 are currently producing milk for human consumption. With the absence of milk samples at these stations, broad leaf vegetation sampling was performed.

Broad leaf vegetation was not sampled at a control location during the months of January, February, April and December of 1987. No broad leaf vegetation was present at the control location due to cold weather during January, i February, and December. In April, samples were improperly split between AP&L and the Louisiana Nuclear Energy Division (LNED). As a result LNED received two control samples and one indicator sample and AP&L received 3 h indicator samples. Milk samples were available from the control location during each of these months. Control station broad leaf vegetation was sampled even when control station milk samples were available.

The typical food product sample FPP-1 (soybeans), was not available during 1987 since no crops were grown in this field during the year. This sampling station will remain as part of the REMP due to the proximity of the location ,

with respect to the plant. An alternate sample, FPP-2 i (sugarcane), was taken in place of FPP-1. A description of .

both locations is contained in Table 2-2.

l 3.5.2 Missed Lower Limits of Detection ;

All lower limits of detection specified in Table 4.12-2 of l Waterford 3 SES Technical Specification 4.12.1 were !

attained during 1987.

3.5.3 Changes to the REMP f

There were no changes to the RENP during 1987.

3.6 Annual Land Use Census Results [

In compliance with Waterford 3 SES Technical Specification 4.12.2, the annual land use census was conducted on August 25 and 26, 1987.

The nearest residence, garden, and milking animal in each sector within a five mile radius of the plant were found by visual l inspection and verbal inquiry. The results of the 1987 census are i given in Table 3.2. No new residences, gardens, or milking l animals were found. i 28 f

W390370SA l

The distance to the nearest vegetable garden in Sector R as well as the distances to the nearest residences in Sector E, F, N, and R were reported incorrectly in last year's census results. The correct values are given in Table 3.2 The owner of the animals at station MKQ-1 stated that the cows were not producing milk for human consumption. The owner of milking goats at location MKE-4 stated that the goats were not producing milk for human consumption. Although no samples were available from either location during 1987, the stations will remain as part of the REMP and the owners will be contacted periodically to determine the status of obtaining samples.

4.0 CONCLUSION

S The radiological environmental data collected during 1987 are consistent with the data obtained during 1986, 1985 the Preoperation Environmental Radiological Surveillance (PERS) Program and during the first two years of the REMP prior to Waterford 3 SES initial criticality. The only man-made radionuclides detected out of all of the environmental samples analyzed during 1987 were cesium-137 and tritium. Cesium-137 was detected in one shoreline soil sample and two control location milk samples. The detected activity in all three instances was at levels less than required by the Technical Specification's lower limits of detection and far below levels which require prompt notification. The origin of this man-made radioactivity is most likely attributable to fallout from past nuclear weapons detonations and not Waterford 3 SES operation. Tritium was detected in one groundwater sample. Tritium is naturally produced and due to the large uncertainty associated with this result, the fact that tritium was detected at levels below the typical lower limits of detection and the presence of tritium in samples taken prior to Waterford 3 SES operation, it is not likely that it was reactor produced.

In conclusion, based on the evaluation of the REMP data collected during 1987 the operation of Waterford 3 SES had no observabic radiological impact on the environment.

E-1.0 ANALY'IS OF SAMPLES FOR GROSS BETA ACTIVITY E-1.1 Air Particulates After a delay of three or more days, allowing for the radon-222 and radon-220 daughter products to decay, the particulate filters were counted in a gas-flow proportional counter.

E-1.2 Water A kaown volume of water, usually 200 milliliters was evaporated to near dryness, transferred to a two inch diameter planchet, and l then evaporated to dryness. The planchet was then counted for l 100 minutes in an automatic alpha-beta counter.

E-2.0 ANALYSIS OF WATER SAMPLES FOR TRITIUM A known volume of water, 5 milliliters, was added to a liquid scintillation solution, 15 milliliters, in a 15 milliliter vial. The sample was then counted for 500 minutes in a liquid scintillation counter.

E-3.0 ANALYSIS OF SAMPLES FOR 10 DINE-131 E-3.1 Milk and Water For samples sent to AP&L, up to four liters of a sample were thoroughly mixed with a stable iodine carrier solution. The sample was then eluded through an anion exchange resin column to remove iodine from the sample. The iodine was then stripped from the resin with sodium hypochlorit. solution, reduced with hydroxylamine hydrochloride, and then extracted into carbon tetrachloride as free iodine. It was then back-extracted as iodide into sodium bisulfite solution and precipitated as palladium iodide. The precipitate was precipitated as palladium iodide. The precipitate was weighed for chemical yield and mounted on a nylon planchet for low level beta counting. The chemical yield was corrected by measuring the stable iodide content of the milk or water with a specific ion electrode.

E-3.2 Broad Leaf Vegetation For samples sent to AP&L, the iodine analysis was performed using gamma spectroscopy. The time between sample receipt and analysis was minimized as well as the sample size and count times adjusted in order to attain the required lower limit of detection. Refer to Section E-4.2 for a description of gamma spectroscopy procedure.

E-4.0 GAMMA SPECTROSCOPY ANALYSIS E-4.1 Milk and Water For samples sent to AP&L, a 3.5 liter Marinelli beaker was filled with a representative aliquot of the sample. The sample was then counted for a minimum of 420 minutes with a shielded Germanium detector coupled to a computer based data acquisition system that performed pulse height analysis.

E-4.2 Vegetation, Food and Garden Crops, and Fish As much as possible (without drying) of a vegetation, food, or garden crop sample was loaded into a tared Marinelli beaker and weighed. The sample was then counted for a minimum of 420 minutes with a shielded Ge(Li) detector coupled to a computer based data acquisition system which performed pulse height analysis.

As much ao possible (up to the total sample) of the edible portion of a fish was loaded into a tared Marinelli beaker and weighed. The sample was then counted for a minimum of 420 minutes with a shielded Ge(Li) detector coupled to a computer based data acquisition system which performed pulse height

. analysis.

E-4.3 Soils and Sediment Soils and sediments were dried at low temperatures, less than 100 degrees Centigrade. The soil or sediment was loaded into a tared Marinelli beaker and weighed. The sample was then counted for at least four hours with a shielded Ge(Li) detector coupled to a computer based data acquisition system which performed pulse height analysis.

( E-4.4 Charcoal Cartridges (Air Iodine)

For samples sent to AP&L, charcoal cartridges were counted in a l Marinelli beaker, with one cartridge pocicioned on the face of a Germanium detector and up to six cartridges on the side of the Germanium detector. If no iodine-131 was detected, the detection limit for the batch of cartridges counted together was determined using the smallest sample volume of the individual cartridges within the batch. If iodine-131 was observed in the screening count of a set of cartridges, each cartridge was then counted separately, positioned on the face of the detector. A separate counting geometry was established for each Germanium detector.

l E-4.5 Air Particulates The weekly air particulate filters for a quarterly composite ,

from each field station were aligned one in front of another and !

then counted for a minimum of four hours with a shielded Ge(Li) !

{ detector coupled to a computer based data acquisition system i which performed pulse height analysis.

E-4.6 Computer Software A computer software program defined peaks by certain changes in the slope of the spectrum. The program also compared the energy of each peak with library of peaks for isotope identification and then performed the radioactivity calculation using the appropriate fractional gamma ray abundance, half life, detector efficiency, and net counts in the peak region.

E-5.0 EhTIRONMENTAL DOSIMETRY Thermoluminescent Dosimeters (TLDs) manufactured by Panasonic (model UD-814AQ) were used for environmental dosimetry. The Panasonic TLDs contained one lithium borate and three calcium sulfate phosphor elements. However, only the calcium sulfate phosphor elements were used. Two annealed dosimeters were placed inside a plastic bag and '

mounted in an aluminum frame prior to placement in the field. The dosimeters were exchanged every quarter. The exposures of the collected dosimeters were read using an automatic TLD reader manufactured by Panasonic (Model UD-710). '

APPENDIX F STATISTICAL ANALYSES 101 H.190370SA

F-1.0 CALCULATION OF MEAN AND STANDARD DEVIATION The mean and standard deviation for different groups of analyses were calculated using the following equations:

n x I

(F-1) x = [*

i=1 "x "x 0.5 E *i - (n )g (R)2 I"

(F-2) s= , gy where:

x = mean of sample population, s = standard deviation of sample population, n*= number of samples in sample population, and x = value of the i'th sample.

F-2.0 COMPARING WO SAMPLE POPULATION MEANS The means of two sample populations can be compared for a 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 f'r both populations. The standard "t" test tests the hypothesis that tue 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) t =

0.5 0.5 2

[(n, - 1)s,2 + (n y- 1)s y g 3 n n

( "x + "y - 2 x y where:

t = calculated "t" value, x = mean of first data set, y = mean of second data set, n = number of variables in first data set, s* = standard deviation of first data set, n* = number of variables in second data set, and s7 = standard deviation of second data set.

Y 102 6390370SA

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)):

(F-4) t=

d (n) 0.5 s

d where:

d = the average of tha difference between the correlated data points frott the two sample populacions:

N d = E (x g- y g)/N i=1 x = the i'th data point from population x, yf= thel'thdatapointfrompopulationy, N = the number of correlated pairs of data points, n = degrees of freedom, for equation F-4, n=N-1, and sd= the standard deviation of the difference between the correlated data points.

The calculated "t" value in both cases is used to test the hypothesis that the true mean of the first population (g ) is equal to the true mean of the second population (4 ) assuming that the true standard deviations of both populations ate equal (r = o- The calculated "t" value is compared to a tabular "t" value suEh thl). t:

a. if t,)t,,n then reject the hypothesis when A x g,

b. if t(-e .nx then reject the hypothesis whenA ,

c. if ltl > t d/2.n thenrejectthehypothesiswhen/4=4, x where e and t are the tabular "t" values, with a preselected error (5 dcent is,Ehis case), confidence level (1-*) or (1-*/2), and degrees of freedom n (n=n +n -2 for Equation F-3 and n=N-1 for F-4, respectively). Tabular values of the "t" were obtained from the CRC Standard Mathematical Tables, 26th Edition (1981).

F-3.0 TLD MEASUREMENTS The TLD measurements made during 1986 were grouped into categories based on distance from the plant. The means and standard deviations obtained for each category are given in Table F-1. The mean dose from the stations located more than five miles away from the plant were compared to the mean dose from stations located within two miles from the plant and to the mean dose from stations located between two and five miles from the plant using the standard "t" test. The "T" values were calculated using Equation F-3 and are given in Table F-1.

Comparing the calculated and tabular "t" values show that the mean dose for stations within two miles from the plant is statistically identical to the mean dose from stations located greater than five miles from the plant. The mean dose for stations located between two and five miles from the plant is statistically the same as the mean dose for stations located more than five miles from the plant.

F-4.0 GROSS BETA ACTIVITY ON AIR PARTICULATE FILTERS The means and standard deviations for airborne gross beta results obtained during 1986 from the control and indicator stations are given in Table F-2. The mean from each indicator station was compared to the mean from the control station using the standard "t" test to determine if there was a statistical difference. The calculated (using Equation F-3) and tabular "t" values for each indicator / control station comparison are given in Table F-2. Comparing the calculated and tabular values indicate that there is no statistical difference between the means from each indicator location and the mean from the control location.

F-5.0 GROSS BETA ACTIVITY IN MONTHLY DRINKING WATER COMPOSITES The mean and standard deviations for gross beta activity detected in the monthly drinking water composites obtained during 1986 from the control and indicator stations are given in Table F-3. The mean from each indicator station was compared to the mean from the control station using the standard "t" test to determine if there was a statistical difference. The calculated (using Equation F-3) and tabular "t" values for eacit indicator / control station comparison are I given in Table F-3. Comparing the calculated and tabular values indicate that there is no statistical difference between indicator stations DWG-2 and DWE-5 and control station DVP-7 means.
