I ABSTRACT l

i

) I Thir; report is issued pursuant to Waterford 3 SES Technical Specification 6.9.1.7. Its purpose is to discuss the Waterford 3 SES Radiological j Envirencental lionitoring Program (REMP), present the results of the program I, for the year of 1988, and to evaluate the radiological . impact en the 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 Wate:: ford 3 SES exhibited no .

discernable impact on the levels of radioactivity in the environment during

) 1988.

2.0 PROGRAM DESCRIPTION

) A gereral summary of the REMP is given in Table 2.1. Brief descriptions I 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 description of the overall REMP is discussed in the following chapter.

2.1 History and Development {

)

The Waterford 3 SES REMP was initiated in April of 1983. The program evolved from the Preoperational Environmental Radiological j Surveillance (PERS) program which was conducted from 1970 through i 1982. The equipment, procedures, techniques, and many of the same ]

sampling locations used during the preoperational survey were

)

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

when Waterford 3 SES had not yet achSved initial criticality, were used to supplement the baseline data obtained during the PERS Program, r

LP&L personnel were responsible for the proper implementation of

) che REMP and insuring that the program complied with federal reFulatory requirements and Technical Specification requirements.

Specific responsibilities of LP&L personnel included collecting (with the exception of fish samples), preparing, and shipping of l environmental samples; conducting environmental dosinetry 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 j Regulatory Commission.

The primary contractor, the Technical Services Department of Arkansae Power 6 Light (i.P&L) located in Little Rock, Arkansas, w.w responsible for perforring radiological analyses; conducting the initial data review; preparing monthly and annual results

) reports; and overseeing laboratory quality assurance and control. I 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

)

The types of samples collected, the analyses performed, the sample collection frequencies, and the location of the semp]1rg stations are summarized in Tables 2.1 and 2.2. The information contained in these tables is based on the requirements specified in Tabic 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 which are the tcps

) required by Waterford 3 SES Technical Specification 6.9.1.7. Any deviations from the REMP (i.e., unavailable comples and missed 3

1 lower limits of detection) observed during 1988 are discussed in 1 Section 3.5. Changes made to the REMP during 1988 as a result of I

) the annual land use census are also discussed in Section 3.5. f l

The environmental samples collected were "lassified into four j general categories according to exposure pathways: direct l 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.

i 2.2,1 Djrect Radiation Exposure Pathway Samples Integrated external gamna exposures were determined using j

) thermoluminescent dosimeters (TLDs). Multi-element TLDs )

manufactured by Panasonic were placed at thirty-one locations as follows:

]

l

a. an inner ring of stations, one in each of the si:ttnen ]

meteorological sectors in the general area of the site l boundary, l

) I

b. an outer ring of stations, one in ten of the meteorological sectors in the six to eight kilometer range from the site, and l J

c. the balance placed in areas of special interest (e.g., population centers, schools, etc.) with one

) area serving as a control. .

J The TLDs were exchanged and analyzed quarterly by LP&L )

perscnnel. l 2.2.2 Airborne Exposure Pathway Samples

)

Samples of airborne particulate and radiciodines were collected at five locatlons. 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 a sampling devices. The devices were designed to samp1L 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 perectnej and sent to the contract laboratory for gross '

beta analysis. These filters were composited by the

) contract laboratory on a quarterly baefs for isotopic analysis by gamma spectroscopy.

)

W391174SA

()

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 lodine-131 analysis by gan.ma spectroscopy.

2.2.3 Waterborne Exposure Pathway,famples C) 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.

O Composite drinking / surface water samples were obtcined 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/ SUE-5) locations from the l plant. These composite water samples were collec; '

l biweekly by LP&L personnel. LP&L personnel acidif, d 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 laboratory for gross beta and gamma spectroscopy analyses. The samples were also composited on a quarterly basis for tritium analycle.

O Due to the high water table resulting from shallow aquifers in the vicinity of the site, groundwater discharge could be sampled from a drainage carel. Groundwater samples were obtcined quarterly by LP&L personnel from one sampling location (GWJ-1) using a grab sampling technique. The samples were acidified with hydrochloric C} acid prior to shipment to the contract laboratory for tritium and gamma spectroscopy analyses.

Shoreline sediment samples were obtained semi-annually by LP&L personnel from two sampling stations. One station was loct'ed on the shoreline of the Mississippi River (SHUE-3)

C) nd the other was located en the shoreline of the 40-Arpent canal (SHJW-1). The samples collected were r. hipped to the contract laboratory without further processing.

)

2.2.4 Ingestion Exposure Pathway Samples

) Mia samplea were collected semi-monthly by LP&L pe nnel. 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 samples

) were available from these locations during 1988 (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.

1 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 sampics were shipped to the j contract laboratory without further processing. 1 A food / garden crop sample (sugarcane') was collected at the

) time of harvest by LP&L personnel from three locations 1 (FPP-1, FPH-1, and FPM-1). The samples were collected by normal harvesting techniques at the time of harvest. The samples were sent to the contract laboratory without further processing for iodine-131 and gamma spectroscopy analysea.

) 2.3 Analytical Procedures Brief synopses of the analytical procedures used by A26L and LP&L are given in Appendix E. These synopses are intended to provide an overview of what was done rather than to be step-by-step procedures.

) W391174SA

C)

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 values are the same as the enes given in Table 4.12-1 of Waterford 3 SES Technical Specification 4.12.1. The LLD's are a priori 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 C) are discitssed in Section 3.5.

2.4 Laboratory Ouality Assurance During 1988 AP&L performed a variety of quality assurance analyses. Spiked and blank samples prepared in-house and gp Environmental Protection Agency (EPA) reference samples were analyzed. It was estimcted that between 5% and 10% of all analyses were for quality assurance purpcscs.

AP&L also participated in the EPA radiological interlaboratory comparison (cross-check) program. This quality assurance program and EPA intercomparison satisfies the requirements of Waterford 3

() SES Technical Specification 3.12.3 for interlaboratory comparison.

Participation in this program involved a number of analyses on various sample media typically found in REMP's. As a result of participation in the program, an objective measure of analytical precision, accuracy, and an estimation of bias wet; 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 1988 results of AP&L's participation in the cross-check program.

l 3.0 DISCUSSION OF RESULTS

) Analytical results for the year 1988 are discussed in this section by exposure pathway, type of sample, and analysis performed. The )

analytical results of the REMP are sulmnarized in Appendix A and data for l 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 i

The average dose rates measured at eli stations by both control and ,

indicator Thermoluminscent Dosimeters (TLDs) were 16, 14, 14, and f 15 mrem per standard quarter (90 days) for the first, second, third, and fourth quarters of 1988, respectively. The average of

) 118 indicator location TLD exposures was 15 mrem /st.andcrd cuarter 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, 3rd quarter) and 24 mrem / standard quarter (L-1, let quarter) for all locations.

) Table 3.1 compares the TLD results by direction and die ance from the tacility. Of the 16 indicator sectors, Sector N d .onstrated the highest average of 17 mrem / standard quarter; however, this average exposure is less than the control's 18 mrem / standard quarter. The average exposure rate from TLD'o located within two miles from the plant was statistically lower than the average exposure from stations located more than five miles from the plart

) using the standard "t" teat (see Table F-1, Appendix F). The avernge 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 greater than five miles of the plant.

Therefore, Waterford 3 SES operation did not have a detectable impact on d!. rect radiation e::porures from gamma radiation.

)

3.2 Airborne Exposure Pathway j i

3,2.1 Airborne Particulate j Gross beta activity ranged from 0.005 pCi/ cubic meter (APG-1 and APC-1, 8/8-8/15) to 0.046 pC1/ cubic meter

) (APP-1, 5/23-5/30) with an average of 0.019 pCi/ cubic meter for 259 measurements from all five sampling locations. The average gross beta activity for the control location, APE-30, was 0.020 pCi/ cubic meter ecmpared to i 0.018 pC1/ cubic meter for the four indicator locations '

(APP-1, APO-1, APG-1, APC-1). The control station average is statistica11.y the same as the average from each indicator station using the standard statistical "t" tect

) (see Appendi:: F).

j 22

)

W391174SA

)

i The gross beta activity results obtained during 1988 are consistent with those from 1987, 1986, 1985 and the

) preoperational program. During the preoperational survey,  ;

in periods not significantly influenced by nuclear weapons '

detonations, the gross beta activity ranged between 0.02 and 0.04 pC1/ cubic meter. During the first two years of i the REMP prior to Waterford 3 SES operation, the average gross beta activity for all stations was 0.021 pC1/ cubic  !

meter with a range of 0.006 to 0.5 pCi/ cubic meter.

)

During 1985 the average gross beta activity for the control location was 0.022 pC1/ cubic meter compared to 0.021 pC1/ 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

)

pC1/ cubic meter, respectively. In 1987 the average gross beta for the control location was 0.021 pei/ cubic meter compared to the 0.020 pei/ cubic meter for the four indicator locations.

3.2.2 Airborne Iodine i

) All of the 260 airborne iodine-131 results were below the lower limits of detection which ranged from <0.005 to

<0.030 pCi/ cubic meter (Table B-2). The variability 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 beryllium-7 and naturally occurring potasium-40 in the twenty quarterly composites (Tnble B-3).

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 is considered synonymous with surface water. Results obtained from

) sarples collected and analyzed as drinking water can be designated " surface water results". Therefore, the results of the mor.thly and quarterly gamma spectral ,

analyses as well as the quarterly tritium analysin i reported as drinking water results are the same as for  !

those reported as surface water results.

, Seventy-eight composite drinking / surface water samples were

) analyzed by a radiochemical procedure for iodine-131 (Table B-4). No ar*..vity was detected at any of the indicator static:.s and all but 1 measurement satisfied the 23

)

W391174SA

_l

)

LLD's with the exception at location DWE-5 for 1/18 to 1/26 )

where the LLD was 1.2 pCi/1. Three of the control

) measurements indicated detectable levels of iodine at an average concentration of 0.6 pC1/1. Two control locations had LLD's of 1.1 pC1/1 which is above the required limit.

The samples were composited on a monthly basis and analyzed by gamma spectroscopy. Cesium-134 and cesium-137 were y

detected at all 3 sample locations for the 1/4/88 to 2/1/88 composite period. As a result, composite periods were shortened to a two week period and for the period 2/1/88--

2/15/88 cesium-134 and cesium-137 were again ccen in all 3 J composite samples. In addition, cobalt-58 was sean in DWP-7, the control location. An investigation was initiated following the January composite results and all

) possible contamination sources were analyzed. Identical l samples split with the Louisiana Nuclear Energy Division (LNED) showed no indication of activation or fission ,

products for this time period. By procedure, the state's i samples were not acidified prior to shipment c.nd it was l discerned that the acid uued could bave been the contamination source. The acid used to stabilize our

) samples, when analyzed, con 6ained low levels of cobalt-58, cesium-134 and cesium-137. Subsequent investigation determined that this acid had been prepared in the plant's radiochemistry laboratory with contaminated glassware and i had not been adequately surveyed prior to exiting the Radiation Controlled Area (RCA). Fresh acid wee prepared and the problem was resolved. Since these contaminants f

) concentrations are an artifact reculting from the l contaminated acid and since the state's samples j demonstrated no activity above minimum detectable limits no dose calculations are warranted. Other than the above mentioned incident, no man-made gamma emitters were detected above their respective lower limits of detection.

)

The monthly composites were analyzed for gross beta activi:7 Gross beta activity was detected in thirty-six of the thirty-nine composites with an average activity of 6.1 pCf/ liter. l The average activity for the control location was 5.5 pCi/ ]

liter, compared to the averages of 3.2 and 5.7 pCi/ liter for )

indicater stations DWG-2 and DWE-5, respectively. The

) average gross bata activity detected at indicator station DWG-2 is statistically the same as that of the control station DWP-7 usir.g the standard "t" test (see Table F-3, Appendix F). The average gross beta activity at statien DWE-5, five milen downstream, is also statistically the came is the control station crerage using the standard "t" test.

) Drinking / surface water samples scre also composited quarterly and analyzed for tritium. Ten of the twelve measurement were below the respective LLD's Tritium 24 W391174SA

C) was found in the first quarter of 1988 at a concentration of 545 !21 pC1/1 at DWE-5, an indicator station, and 323 C) 221 pC1/1 at DWP-7 the control location.

Tritium is naturally occurring and during the preoperatieval program wcs frequently detected in drinking water samples at concentrations ranging between 60-220 pci/1. These detected concentrations are well below the required LLD of g) 2,000 pCi/1 and may be an artifact of the contaminated acid used in the first quarter. Conservatively assuming that all of the tritium detected at DWE-5 originated at the plant, the maximum done to a member of the general public was calculated. The methodology and the assumptions used were based on Regulatory Guide 1.109 (10/77). The dese to the maximum exposed inaividual, a child, was calculated

() by the following equation:

R = (C) (U) (D) (1) where:

R is the annual dose to any organ or the total body in mrem /yr;

() C is the radionuclides concentration in the drinking water sample in pCi/1; U is the amount of water which is ingcated.

assuming that river water 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 g) (2.03E-7 mrem /pC1 ingested).

Using equation (1), which igneres trivial doses from the fish pathway, the naximum annual dose to a child drinking 510 liters of untreated riverwerer was calculated to be 0.056 mrem /yr to any organ or the whole body. Therefore, the radiological impact to the general public is

() incensentential.

a 3 . .) . 2 Groundwater j Five groundwater samplen were collected from one sampling i location, CWJ-1, end analyzed for tritiani and gamma ray emitters. No gamma ray emitters were detected. Trititm was detected in one cf the five camples at a concentration

() of 460 ptli/1 !?ll. Tritium is naturally occurring and i during the preoperational pr< gram, tritium was frequently detected in groundwater samp1sa at concentrations ranging 25 O

)

H between 50 and 180 pC1/1. Although the detected i

concentration is higher than these values, the detected

) concentration has a high degtce on uncertainty associated with it. This value is aban telow the usual lower limit of )

detection. Howevert conservatively assuming that all of the tritium cctivity detected in the groundwater at station GWJ 4 cr:gicatui irom the plant, the maximum dose to a member or 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 i equation:

R = (C) (U) (D) (2)

) where:

R is the annual dose to any organ or the total body in mrem /yr; C is the radionuclides concentration in the groundwater sample in pCi/1;

) U is the amount of water which is ingested, I assuming that this groundwater de ingested without treatment, in 1/yr, given in Table E-5 of Regulatory Guide 1.109 (510'11ters for a child) and l 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 fdertical (2.03E-7 mrem /pCi ingested).

Using equation (1), the maximum annual dose to a chfid drinking 510 litern of untreated groundwater was

)

calculated to be 0.048 mrem /yr to any organ or to the total body. Therefore, the radiological impact to the general public is inconsequential. In addition, this is not a realistic pathwoy as it assumes that the child drinks untreated ditch water.

) 3.3.3 Shoreline Sediment Four snoreline 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 sumos 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, wan detected in the_ sample obtained from station ShWJ-1 at 26

)-

W391174SA

) j i

a concentration of 142 pCi/kg(dry)f and SHWE-3 at concentration'of 43 pCi/kg (dry). No other man-made:

) radionuclides were detectad in any.of the samples, q Radioactive release permits for the year 1988 show that  ;

no cesium-137 was discharged into the drainage. canal from ')

which SHWJ-1.came. Therefore, the presence of tha 1 cesium-137 is'most.likely attributable to. fallout from past nuclear weapons. detonations or.the Chernoby1 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 .

9 preoperational program, cesium-137 was detected in 13 of 18 soil samples at concentrations ranging between 30.and i 890 pC1/kg(dry) with an average concentration of 138 q pci/kg(dry). In 1985, 1986, and 1987 cesium-137 was

)

detected at this site at levels of 99, 65, and'21 pCi/kg (dry), respectively. .1 However, conservatively assuming that all of the cesium-137 activity detected in the shoreline sedirent nt the higher of.the two stations, SHWJ-1 originated from the

) plant, the maximum dose to a member of the general public I 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 maxieum exposed individual, a teenager, was calculated.

by the following equation:

) R = (40) (C) (U) (D) .(3) where:

R is the annual dose to the skin or the total bcdy in mrem / year; 40 is the area-mass conversion factor given in

)

Appendix A of Regulatory Guidei l.109 in kg/ square meter; C is the radionuclides cencertration in the shoreline soil sample in pCi/kg; U is the maximum exposure time given in Table E-5

) of Regulatory Guide 1.109 (67 hours7.75463e-4 days <br />0.0186 hours <br />1.107804e-4 weeks <br />2.54935e-5 months <br /> for a teenager) and D is the external dose conversion factor for standing on contaminated ground given in' ,

Table E-6 of kegulatory Guide l.109 (the values for skin and total body-are 4.9E-09 and-4.2E-09 mrem /hr per pC1/ square meter, respectively).

UsinF equation (3), the maximum annual dose to a teenager spending 67 hours7.75463e-4 days <br />0.0186 hours <br />1.107804e-4 weeks <br />2.54935e-5 months <br /> at the shoreline of the canal was calculated to be approximately 0.002 mrem /yr to the skin 27

and 0.002 mrem /yr to the total body. Therefore, any radiological impact to the general public resulting from

) cesium-137 detected in the shoreline soil is insignificant.

3.4 Ingestion Exposure Pathway 3.4.1 Milk Forty-eight milk samples were collected from two sampling

) locations 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. All man-made gamma emitters were beacw their respective lower limits of detection. Naturally occurring potassium-40 was detected in all cumples.

)

3.4.2 Fish Sixteen fish samples, e1ght 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 Eroad Leaf vegetation i

Veterford 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 J collected reliably from only one sampling location within five miles of Waterford 3 SES, broad leaf vegetation was sampled monthly at two indicator locations. Breed leaf )

vegetation was also collected from one control location. /

Thirty-two broad leaf vegetation samples were collected

)

and analyzed by a radiochemical procedure for iodine-131. )

All measurements were below the lower limits of detection. l The samples were also analyzed by gamma spectroscopy. '

Naturally occurring radionuclides were detected in all of the samples, however no enn-made radionuclides were  ;

detected above their lower limits of detection.

) 3.4.4 Food / Garden Crogs Three food / garden crop samples were collected and analyzed by a radiochemical procedure for iodine-131. Iodine-131' concem:catioc were below the lower linit of ietection. The samples were also analyzed by gaaca spectroscopy.

Naturally occurring potassium-40, radiun-226, and, tellurium-208 were the only redienuclides detected. All

3.5 Deviation from the REMP

) 3.5.1 ' Unavailable Samples During 1988 deviations from the REMP sampling schedule occurred. All of the deviations (with the exception of those associated with TLDs) were either the result of equipment malfunctions or the 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 prevcnt recurrence of the event. Deviationn from the REMP associated with TLDs were beyond the control of LP&L and resulted frem theft of a few of the dosimeters placed in the field. When a dosimeter was discovered missing during

)

a monthly itapection, the TLD was replaced and the deviation noted. A listing of all unavailable samples for 1988 along with associated explanations of why the sampics 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 1988 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 l producing milk for human consumption. With the absence of

]

milk samples at thene stations, broad leaf vegetation j sampling was performed, j

) Broad leaf vegetation was not sampled at a control location during the months of January, February, November and December of 1988. No broad leaf vegetation was present et the control locacion due to cold weather during January, )

February, November, and December. Milk samples were 1 available from the control location durfra ecch of these ,

)

months. Control station broad leaf vegetation was sampled j even when control ctation milk samples were available.  ;

3.5.2 Missed Lower Limits of Detection The lower limits of detection specified in Table 4.12-2 of ,

the Waterford 3 SES Technical Specification 4.12.1 were not l

) attained during 1988 for three drinking water sarples.

Only 1 of these three samples was at an indicator location, DWE-5 for 1/18-1/26. The LLD was not met due to the small sample size. Only a one week sample was used due to the heightened attention to the contaminated ccid incident and reculted in this missed LUD.

I 3.6 Annual Lend Use Census Results j l

I

) In compliance with Waterford 3 SES Technical Specification 4.12.2, the annual land use census was conducted on August 11 and 12, 1988.

The nearest residence, garden, and milking animal in each sector within a five mile radius of the plant were found by visual 3 inspection and verbal inquiry. The results of the 1988 census are j given in Table 3.2. No new residences or milking animals were l found. New gardens were identified in Sectors E, F, C, H, J, and

) M. These new gardens are annual crops (soybeans or sugarcane) which are grown within the site area boundary. These fields were fallow in previous years and were returned to production in 1988.

These fields are Jecsed from LP&L and as such are within the site boundary. Samples were taken from thece fields at the time of harvest and are labelled as FFH-1 cnd FPM-1. Since the critical

) receptor for Waterford 3 SES'is an infant who does not consume food producto, che presence of these producing ficids does not affect doce calculations or justify their permanent. inclusion in the REMP. Also, since they are not irrigated by plant wastes, thece samples are not required and were included for information purperee only.

) The owner of the animals at station MKQ-1 stated that the cows were not producing milk for human consumption. The cwner 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 1988, the stations will remain as part of the REMP and the owners will be contacted periodically to determine the status of obtaining sampler.

4.0 CONCLUSION

S

) The radiological environmental data collected during 1988 are consistent with the data obtained during the prior three years of plant operation (1985-87), the Preoperationa1' Environmental Radiological Surveillance (PERS) Program aid the first two years of the REMP prior to Waterford 3 SES initial criticality (1983-84). The only man-made radionuclides detected in the environmental samples analyzed during 1988 were cesium-137 and tritium. Cesium-137 was detected in two shoreline soil

) samples. The detected activity in both 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 radioactive'_y is most likely attributable to fallout from past i nuclear weapons deranations and not Waterford 3 SES operation. Tritium )

was detected in two drinking water and one groundwater sample. Tritium is naturally produced and due to the large uncertainty associated with

) these results, the fact that tritium was detected at levels below the i typical lower limits of detection and the presence of tritium in camples i taken prior to Waterford 3 SES operation, it is not likely that it wcs ]

reactor produced. j 1

In conclusion, based on the evaluation of the REMP data collected i

) during 1988 the operation of Waterford 3 SES had no significant -

l radiological impact on the environment. {

I-131 was analyzed by several methods for quantification ' including gamma

~

1.-

spectrometry of the liquid milk (3.7 liters); anion chromatography (with precipitate of silver iodide on'2-inch dia, planchet) followed-by beta counting using a low-background alpha / beta detection; and also analyzing the. prac'ipitate

) .

by gamme spectroscopy. All three methods yielded resulta vnrying 6-9 pCi per i liter.

In past EPA intercomparison studies for low-level I-131, the standard deviation was 67 percent of the known value (i.e. , 9+/-6, where 6 is one sigma)'. .The j standard deviation has now been lowered to 10 per cent, thereby increasing j

) performance in accuracy 7-fold.  !

New efficiency curves for I-131 were calculated 20-June-88, and operation of a nev low-backstound alpha / beta detector was begun at this date. .

3. Efficiency calculations for gross alpha values for air p, articulate filters have .

been refigured, resulting in higher alpha efficiency val'oes. Future gross alpha  !

) value,s should agree with EPA Air Filter results.

3. As of August 18, 1988, no environmental radiological monitoring program requires analynis for gross alpha activity. In the future, gross alpha activity will not be reported.

E-1.0 ANALYSIS OF $AMPLES FOR GROSS BETA ACTIVITY

) E-1.1 Air Particulate After e, 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 known volume of water, usually 200 milli 11ters was cycporated to near dryness, transferred to a two inch diameter planchet, and then evaporated to dryness. The planchet was then counted for 100 minutes in an automatic alpha-beta counter.

l y E-2.0 ANALYSIS OF WATI:R SAMPLES FOR TRITIUM A known volume of water, 5 milliliters, was added to a liquid scintillation solution, 15 n111111ters, in c 25 milliliter vial.

The sample was then counted for 500 minutes in a liuuid scintillation counter.

) E -3. 0 ANALYSIS OF SAMPLES FOR 10 DINE-131 )I E-3.1 Milk and Water l For samples sent to AP&L, up to four liters of a sample were i thoroughly mixed with a stable iodine carrier solution. The l sample was theh eluded through an anion exchange resin column to

) remove iodine from the sample. The iodine was then stripped from the resin with sodium hypochlorite solution, reduced with hydroxylamines hydrochloride, and then extracted into carbon tetrachloride as free iodine. It was then back-extracted as iodide into sodium bisulfite solution and precipitated as I 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 anclyris was performed using gamma spectroscopy. The tima between sample receipt and analysis was minimi=ed as well as the sample size and count times adjusted in order to attain the required lower limit cf detection. Refer to Section E-4 2 for a description of gamma  ;

spectroscopy procedure.

Germanium detector coupled to a computer based data acquisition.

)

system that performed pulse height analysf.s.

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 ecunted for a minimum of 420

) minutes with a shielded Ge(L1) detector coupled to a computer based data acquisition system which performed pulse height analysis.

As much as 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 9 minutes with a shielded Go(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 then

) 100 degrees Centigrace. The soil or sediment was loaded into e tared Marina 111 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) )

)

l For samples sent to AP&L, charcoal cartridges were counted in a

{

Marinelli beaker, with one cartridge positioned on the face of a Germanium detector and up to six cartridges on the side of the Germanium detector. 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 indivfdual j cartridges within the batch. If iodine-131 was observed in the j screening count of a set of cartridges, each cartridge was then I counted separately, positioned on the face of the detector. A l separate counting geometry was e.stablished for ecch Germanium j detector. I I

g E-4.6 Computpr Software A ccmpt.ter sof tware progran defined peaks by certain changes in the slepe 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 fractionil gamma ray abundance, half life, detector O efficiency, and net counts !M the peak region.

E-5.0 ENVIRONMENTAL DOSIMETRY The rmoluminercent . Dosimeters (TLDs) manufactured by Panasonic (model LD-314AQ) were used for environmentti docimetry. The Panasonic TLDt coa:ained one 11thium borate and th ee calcium sulfate phosphor O elesents. However, only the calciut sulfate phosphor elements were reed. Two annealed dosimeters were placed inuide a plastic bag and mounted in an 61uminum frcme prior to piecement in the field. The dosimeters were exchanged every quarter. The etposures of the collected dosimeters were read using an automatic TLD reader manufactured by Panasonic (Model L'D- /10) .

F-3.0 TLD MEASUREMENTS

) The TLD measurements made during 19S8 were grouped into ca eraries based on distance from the plant. The means and standard duviations obtained for each category are given in Table F-1. The mean dose from j the stations located more than five miled 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 mi?.es from the plant using the standard "t" test. The "t" values )

)

were calculated using Equation F-3 and are given in Table F-1. l Comparing the calculated and tabular "t" values show that the mean dose for stations within two miles from the plant is statistically lower than the mean dose from stations located greater than five miles from the plant. Tbn mean dose for stations located between two and five miles from the plcnt is statistically the sure at the rean dose for

) stations locited more than five miles from the plant. j l

F-4.0 GROSS BFTA ACTIVITY ON AIR PARTICULATE FlLTERS The means and standard deviations for airborne gross beta results  !

obtained during 1988 from the control and indicator stations are given i 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-?. Comparing the calculated and tabular values indicate that therr io no statistical difference between the means from each indicator location and the mean from the control location.
