1. Introduction and Sumary l

This report presents a sumary of the results of measurements of direct radiation and radioactivity in environmental media in the vicinity of the Pilgrim Nuclear Power Station - Unit 1 (PNPS-1) and at selected control locations for the period .lanuary 1 - December 31, 1983. The results of this Program indicate that PNPS-1 has had a negligible and most often insneasurably small impact on the environment in the vicinity of the plant. Conservatively, estimated doses resulting from the measured highest station mean concentrations are typically less-than 1% of the doses resulting from naturally occurring radionuclides and residual fallout from previous atmospheric nuclear weapons testing.

Estimates.of concentrations of radionuclides in vegetation and milk and estimates Jof dose to man, as quoted in this report, were made using methods similar to those described in Regulatory Guide 1.109 and 1.111.

The performance record of the PNPS-1 for the calendar year of 1983 reflects an average capacity factor of.80.35. Monthly capacity factors are given in Table I-1.

'A tabulation of radioactive effluents from the PNPS-1 is provided in Appendix B for the 1983 calendar year.

There were no Ananalous Measurement Reports made for the calendar year of 1983.

l Essentially, all samples required by the PNPS-1 Technical Specifications were collected on schedule. The only exceptions were the unavailability of one milk sample location, three milk samples, one air sampling location from 5/10/83 until 8/23/83, plus occasional failures of the air samplers, and three fish samples and one lobster sample due to unavailability. In addition, a total of eight TLDs were found to be missing from their field locations during 1983.

These incidents affected only about 2% of the total number of samples scheduled for collection.

The Plimoth Plantation was not available as a milk sampling location during 1983. Plimoth Plantation inforned Boston Edison in January 1981 that milk producing animals would no longer be available as they disposed of their cow. This situation had not changed for 1983. During 1983

., three milk samples were unavailable from the Plymouth County Farm. ~These unavailable samples occurred in early May, late July and late September.

l The East Breakwater air sampling station was without power from the week of 5/10/83 until the week of 8/23/83. loss of power to this air sampling station was immediately reported to the Control Room upon discovery on 5/10/83.

II. Des ~cription of the Monitoring Program The Radiological Monitoring Program conducted in accordance with the PNPS-1 Technical Specification is included as Appendix D. The program is essentially identical to that conducted during 1982 and incorporates supplemental provisions as specified in the Settlement Agreement between the Massachusetts Wildlife Federation and Boston Edison Company, June 9, 19772 . The exceptions to the program are as follows:

1) 'There is no TLD station at Saquish Neck since the Mass Wildlife
Federation has not yet provided a means for placement and retrieval of the TLD as prescribed by the agreement noted above.
2) There is no longer a milk producing cow at Plimoth Plantation. The
Plinoth Plantation location has been unavailable since 1981. The nearest dependable cow location is at the Plymouth County Farm, which is 3.5 miles from PNPS in the West sector.

'3) There is no longer a Karbott Farm. Vegetable samples are now collected at the the nearest gardens near the W and ESE site boundaries.

.The 1983 site Census conducted according to Technical Specification l

requirements determined that there are several vegetable gardens near the site boundary in the W-WNW and SE-ESE sectors (see Appendix E). In the ESE sector, the nearest garden is at the J. B. Work residence (0.6 miles ESE). A sample nf chinese cabbage was collected on 9/27/83. In the west direction, the location of the nearest observed garden of approximately 500 square feet was at the residence of M. Lloyd Evans (0.7 miles W). A sample of rhuhbarb was collected f rom this location on 9/27/83.

l l

2-1

J In addition to the above, a sample of lettuce was obtained from the Whipple Farm (1.5 miles SSW) on 9/27/83.

I The 1983 Census indicates that 5 goats are located at the Lloyd residence on Long Pong Road, however they are miniature goats (not full size) and the milk is .used for personal consumption only. Two goats were located at the Raymond residence but are no longer available at this location.

During 1983 every ef fort was made to identify.and locate milk-producing animals in the near vicinity (5 miles) of PNPS-1. The Plymouth County Farm (3.5 miles W) agreed to reparticipate in the Environmental Program in December of 19112 and sampling continued throughout 1983. The Plimoth Plantation declined to participate in the Program. The only other available milk-producing cow within 5 alles of-PNPS is located on Beaver 4

Dan Road ~(2.5 miles S) and is owned by C. Mann. Mr. Mann provided three milk samples during 1983 (June . July and Septehr), .and stated that milk samples will again be provided starting in the. spring of 1984.

In' perspective, cows and goat locations within.a 5 mile radius of PNPS-1 are rare and transitory at-best. It is extremely unlikely that the cow-milk pathway could be responsible for even small doses to any member of the general public.

- III.Results and Analyses This section summarizes the results of the analyses of environmental media samples in compliance with the monitoring program described in Appendix D.

The section is divided into sub-sections, each of which describes a particular media or potential exposure pathway.

The results of analyses conducted on environmental media are maintained in a computerized data file which constitutes a data base used for statistical analyses by a computer code entitled ERMAP .

ERMAP calculates a set of statistical parameters for each radionuclide whose concentration is reported in a given environmental medium. This set of statistical parameters includes separate analyses for (1) the indicator stations, (2) the control stations, and (3) the station having the highest annual mean concentration. For each of these three groups of data, ERMAP calculates:

l

1) the mean value of all measured concentrations;
2) the square root of the mean square deviation (this is an estimate of the sample variance);
3) the lowest and highest calculated concentrations;
4) the number of positive measurements divided by the total number of measurements.

3-1

(

Entries listed under the heading LLD* are the mean of all LLD values, where each LLD equals 4.67 times the standard error of the associated background measurement.

The results of ERMAP are provided in each subsection for the appropriate nedia.In addition, plots of measured concentration as a function of sanpling time are included for certain isotopes in certain media in an i

effort to simplify interpretation of the results.

Sample station identification numbers used by the ERMAP program are provided in Table III-A-1.

III.A. Air Particulate Filters Sample collection systems consisting of a cellulose particulate filter and a charcoal filter cartridge are used to collect particulate matter and iodine isotopes respectively. Analyses of the particulate filters for beta radiation is performed weekly. In addition, quarterly composite particulate samples are analyzed for gamma emitting isotopes. Table III-A-2 presents the results of the ERMAP for air particulate analyses. (The station identification numbers correspond to the locations identified in Table III-A-1).

For ease of interpretation of these measurements, a plot of gross beta activity vs. time for all indicator stations is provided in Figure III-A-1 and for the control station in Figure III-A-2.

Positive measurements of specific isotopes characteristic of reactor operation were not observed in any of the quarterly composite samples.

The MDC for gross beta analysis for Station #00 (Warehouse) collected on B/9/83 was not met due to a broken connection between the filter and the pump, thus the volume was unknown. The only positive measurements observed in the quarterly composite samples were.due to naturally occurring nuclides (Be-7, AcTh-228 and K-40).

Therefore, there was clearly no significant environmental effect observed in the air particulate nedia as a result of the operation of PNPS-1.

III.B. Iodine The same sample collection systems used to collect airborne particulates are used to collect gaseous iodine on a charcoal filter cartridge. The cartridge is removed and analyzed for I-131 weekly.

The results of the ERMAP program for this media are provided in Table III-B-1. It is not apparent from this table that the mean value of the calculated concentrations for the indicator stations is greater than the mean value for the control station. The results of these analyses are presented graphically in Figure III-B-1 for the indicator stations and' Figure III-B-2 for the control station.

The MDC for iodine analysis was not met for two samples at Station #00 (Warehouse). For the sample collected on 7/26/83, the MDC was not met due to a low sanple volume which was the result of a kinked sample line. For the sanple collected on 8/9/83, the MDC was not met due to a broken connection between the filter and the pump, thus the volume was unknown.

There was clearly no significant environmental effect observed in the airborne gaseous iodine collection media as a result of the operation of PNPS-1.

'l III.C. Soil Soil surveys at eleven locations are required once every tnree years in compliance with the revised Technical Specifications which went into effect on April 19, 1977. These in-situ surveys were conducted during May, October and December of 1982. The results of these surveys are included in Appendix C of this report.

l III.D. Direct Radiation

1. Continuous Thermoluminescent Dosimetry Thermoluminescent dosimeters (TLD) of the CaSO 4 (Dy) type are used to record direct gamma radiation from all sources including direct and scattered radiation from Nitrogen-16 in the turbine building, and cosmic and other natural and artificial gamma radiation. TLD's are installed at the locations identified in Table III-D-1.

Tables III-D-2 through III-D-5 show quarterly average doses from direct gamma radiation in uR/hr at these stations.

The measured values for the fourth quarter (Table III-D-5) indicate a problem with the majority of the TLDs used in this quarter. There were no abnormal occurrences at the Station or in the environment during this time period, and the same procedure was used in processing the TLDs. The insnediate action taken to rectify this situation was to remove the suspect TLDs f rom the program.

In addition to average doses for each TLD for each readout period, geographic regional average doses for sectors of different nearness are computed; viz, in immediate proximity to PNPS, more distant but near the site boundary, up to several 3-15

4 miles away " neighborhood", and far away (background). Each set of data show consistent trends; the near plant dosimeters (primarily OA, PB, and WS) stand out among all readings and have an average above the dose rates further away. The next region has a lower average dose rate, and beyond 0.7 miles (distant neighborhood and background) the dose rates are statistically I consistent. In all cases, the near plant levels are distinctly higher than those of f-site and of f-site dose rates are not significantly sensitive to distance variations beyond the site itself.' Thus, beyond the " exclusion area" (for this purpose, the 0.25-0.7 mile region), dose rates show no significant plant effect;. populated areas are therefore beyond the limits of elevated dose rates.

2. Field Survey A gamma exposure survey of Plymouth Beach and Priscilla/ White Horse Beach was conducted during August of 1983. The results of this most recent survey are in agreement with the last six beach surveys : conducted for 1977 through 1982. In addition, a comprehensive soil survey of 11 locations was conducted during the spring and fall of 1982. This study included both gamma

( exposure rate measurements and in-situ ganna spectrometry analysis for each location. Laboratory soil analyses were also conducted for selected locations. The results of this study are presented in Appendix C. The latest ganne exposure survey was I

conducted using a Reuter Stokes RS-lli high pressure ion chamber (HPIC), Serial Number 4-1656. The design and calibration of this ,

instrument were described in the above report.

The present survey was designed to detect differences in the externai exposure rate encountered at beaches near the plant j

(Plymouth and Priscilla/ White Horse) and a control location (Duxbury). The detector's calibration was checked before each measurement. The data (Table III-D-7) indicate that the exposure '

rates at Plymouth Beach (behind Berts Restaurant) and Priscilla/ White Horse Beach are not significantly greater than

- the exposure rates measured at the control station in Duxbury. ,

The small differences are likely due .to the presence of granite beach stones which.are essentially absent at the Duxbury location. It has been demonstrated that proximity to beach stones results in higher exposure rates than in sandy areas (see Annual Report No.10) .

This survey indicates that the natural background exposure rate at beaches near Pilgrim Station is probably 6-9 uR/hr. These results are in couplete agreement with similar measurements performed in Maine , where the natural background exposure rate at shoreline locations nas found to vary between 6.6 and 14.5 uR/hr. These exposare rates were also found to vary directly 5

with the size and proximity of granite outcroppings ,

3-17

These latest measurements are also in agreement with the soil survey mentioned earlier. The results of that survey indicate that of f site dose rates have a range of 9.3 to 10.5 uR/hr with an average of 9.7 uR/hr.

III.E. Waterborne Samples of seawater are collected at three locations, the Station Discharge Canal (Station 11), Bartlett Pond (Station 17 - 1.7 mi - SE) and Powder Point (Station 23 - 7.8 mi - NNW). The Discharge Canal sample is collected by a continuously compositing saneler which extracts a sample of about 20 ml of water from the Discharge Canal every one-half hour. Grab samples are taken weekly from each of the other two locations.

The results of the ERMAP program for seawater samples are presented in Table III-E-1.

There were no positive measurements Jof isotopes characteristic of reactor operation observed at any of the three sampling locations. ~ The only positive measurements observed .were due to naturally occurring isotopes (K-40 and AcTh-228).

Therefore, there was clearly no significant environmental effect observed in the seawater media as a result of the operation of PNPS-1.

III.F.. Shellfish Shellfish are normally sampled quarterly from 5 locations: the Station Discharge Canal, Duxbury Bay, Manomet Point, Plymouth Harbor and Marshfield. The results of the ERMAP program for shellfish are presented in Table III-F-1. It is clear from this table that there have been positive measurements of Be-7, Co-60, AcTh-228 and K-40 in samples from the Discharge Canal. In addition there have been positive measurements of-Be-7, Mn-54 (peak), Co-60, AcTh-228 and K-40 at Manomet Point;~ Be-7,'AcTh-228 and K-40.at Plymouth Harbor; AcTh-228 and K-40 at Duxbury Bay; and, Be-7, AcTh-228 and K-40 at the control :;tation in Marshfield.

The observed. concentrations.of Co-60 and Mn-54 peak are most probably the result:of PNPS-1 liquid releases. However, the observed concentrations of Be-7, AcTh-22R and K-40 are due to the natural occurrencecof these nuclides.

However, even if a persen were to consume the maximum annual quantity of seafood (5 kilograms / year)-with-the highest mean concentrations of Co-60 and Mn-54 (peak), they.would receive a dose of less than 0.001 mrem to the . total body and less than 0.01 arem to the most restrictive organ (Adult, GI-LLI).

When compared to the natural background dose rate of 80-100 mrem / year, there was clearly no significant environmental impact observed in shellfish as a result of the operations of PNPS-1.

III.G. Alaae (Irish Moss)

Algae, referred to as Irish Moss or Chondrus Chrispus, is sangled quarterly at three locations, the PNPS Discharge Canal, Manomet Point and E111sville. The results of the ERMAP program for Algae are presented in Table III-G-1.

It is clear from this table that there have been positive measurements

. of Be-7, Co-58, C0-60 AcTh-228 and K-40 at the Discharge Canal. In

. addition, there have been positive measurements of Be-7, Co-60 (peak),

'AcTh-228 and K-40 at Manomet Point (Station 15 - 3 miles - SE); and Be-7, AcTh-228 and K-40 at the control station of Ellisv111e (Station

.22 .8 mi - SSE) .

The measured concentrations of Co-58 and'Co-60 at the Discharge Canal

are certainly due to liquid effluents from PNPS-1. The observed

. concentration of Co-60 (peak) at Manomet-Point is most probably the result of PNPS-1 liquid releases. 'There were 1no positive measurements of reactor related isotopes at the control station in.E111sv111e,

approximately eightleiles away.

It is hoortant to note that due to processing and market dilution, the presence of the Co-58 and Co-60 concentrations do not' represent a significant potential source of dose to the general public. In fact, even direct human consunption of Algae (which to our knowledge, does 3-32

not occur) with the highest mean concentrations would result in a dose rate of about 0.002 mrem /yr to the total body and less than 0.02 mrem /yr to'the most sensitive organ ( Adult-GI-LLI, using the models presented in Regulatory Guide 1.109) and assuming consumption of 5 kg/ year of unprocessed material. When compared with the natural background dose rate of 80-100 mrem /yr, there was clearly no i significant environmental impact observed in Algae as a result of:the operation of PNPS-1.

III.H. Lobster ( ArthroDods)

Lobster samples are collected four times per season in the vicinity of the Discharge Canal Outfall area and annually at a distant point offshore. Only one of the required samples from the Discharge Canal Outfall area was not obtained due to unavailability in the first quarter of the year. The results of the ERMAP program for lobsters are presented in Table III-H-1. These results are unremarkable in that there were no positive measurements of any isotopes other than K-40 in either the indicator or the control samples (K-40 is a naturally occurring isotope). Therefore, there is no evidence of any environmental impact'on this media as a result of the operation 'of PNPS-1.

III.I. Fish Fish samples of Bottom Oriented (Group I) and Near Bottom (Group II) species are collected quarterly in the vicinity of the Discharge Canal Outfall. In addition, samples of Anadromous (Group III) and Coastal Migratory (Group IV) species are collected when in season, in this same area. Lastly, a sample from each group is collected once per year at a distant location offshore. During 1983, one Group I sample was unavailable in the third quarter, and two Group II samples were unavailable in the first quarter.

The result of the ERMAP program of fish are. presented in Table 111-I-1. ~There was a positive measurement of Es-137 at the indicator station (Discharge Canal - Station 11) during the fourth quarter.

A winter flounder sample collected on 11/17/83 at the Discharge Canal outfall Area indicated a positive measurement.cf Cs-137. The winter flounder is in the Group I . category (Botton.Driented). Even if an individual.were to consume the nazimum annual quantity of fish (21 kilograms / year) with .the highest mean concentration of Es-137, .they would receive a dose of less than 0.06 uren to the total body and about D.08 area to the most restrictive organ ( Adult - Liver). Therefore, there is little evidence of any environmental inpact on this media as a result of the operation of PNPS-1.

4 III..). Sediments Sediment samples are taken semi-annually at five indicator stations including Rocky Point, Plymouth Harbor Duxbury Bay, Plymouth Beach and Manomet Point and a control sample is taken f rom Marshfield. There is a detailed subdivision of individual sample cores in which samples are sectioned into'2 cm increments during the first half of the year (this

' applies to all locations except Plymouth Beach), and samples are

. sectioned into'S cm increments during the second half of the year.

i e

The surface and alternate sections are analyzed for'ganum emitting isotopes. In addition,'the surface section from each core and a mid-depth section from:Socky Point and Plymna.th Harbor are analyzed for Pu-238.and Pu-239.:240.

The results of .the ERMAP program for sediments are presented in Table j .III-J-1. It is clear from this table that Es-137 was observed in a sediment sample (16-18:cm) taken from Duxbury Bay (Station 13). This sangle. ass collected on'5/31/83. In addition. Es-137 ans observed in

.the majority of .the sedient segments (D-26 cm) obtained from Duxbury Bay on '5/31/83, and was : observed in all of the sediment segments (0-15 cm) collected on 10/13/83. The observation of Cs-137 aas also made at

' Rocky Point (28-30 cm, collected on 5/31/83), Menomet Point (20-22 cm, collected on 5/31/83), Plymouth Harbor (0-18 cm, collected on 3-42 l_--________ _ _ _ . _ _ . . _ _ _ _ _ _ _ . _ _ _ _ _ _ _ _ _ _ _ _ ___ _ _ _ _

- 5/16/83; 0-15 cm, collected on 10/11/83), and at Marshfield (4-22 cm, collected on 5/2/83; 0-15 cm, collected on 10/13/83). The concentration of Cs-137 at the 28-30 cm level from Rocky Point was most

. likely due to controlled liquid releases from PNPS-1. The concentrations of Cs-137 at Duxbury Bay may be explained by the fact that the sediment samples have a silty character not common to the other samples. The Plymouth Harbor sediment is very similar to Duxbury l 8ay. It may be that the nature of the Duxbury sediment is such.that i

I certain materials are retained more strongly than others. This theory is supported'by the fact that the Duxbury station also had the highest mean concentration of K-40, an isotope which is chemically similar to Cs-137. The measured concentration of Be-7, and to some4 extent Es-137 l at Duxbury Bay, Piymouth Harbor and Marshfield, and the ts-137 at l

Manomet Point. are attributable to the fission products related to fallout f rom previous weapons testing.

i

Analyses for plutonium isotopes in sediment : samples were .perfomed -by the EAL Corporation (formally LFE Environmental Analyses. Laboratories)

! in Richmond, California. The results of these analyses are presented in Table III-J-2. There is no apparent trend in these data to indicate i

that the PNPS-1 is contributing measurably to levels of Pu-238 or 239, 240 in the environment since levels of plutonium at Rocky Point are among the lowest measured at any location.

III.K.~ Milk Milk samples were collected primarily at two locations during 1983, the Plymouth County Farm,(Station 11 - 3.5 mi - W) and the Whitman Farm (Station 21 - 21 mi - NW). As stated in Section II, three samples were collected from Beaver Dam Road (Station 28 - 2.5 mi - 5) in June, July and September, and all except three samples were collected f rom Plymouth County Farm in early May, late July and early September. Milk samples from Beaver Dam Road will hopefully be collected on a more frequent basis starting in the spring of 1984.

Thus, the only dependable indicator station (within 5 miles) for milk near PNPS-1 during 1983 was from the Plymouth County Farm. ' This was confirmed in the 1983 Census (see Appendix E). When available, samples were collected semi-monthly when animals are on pasture (generally May through October) and montuly at other' times.

The results of the ERMAP program for the milk medis are presented in Table III-K-1. The results of analyses for Cs-137 and Sr-90 are presented graphically in Figures III-K-1 and III-K-2 respectively.

There were no positive measurements or indications of il-131 in any of the samples. However, for the milk samples collected on 7/8/83, the MDC for I-131 analysis was not met due to the loss of sample in radiochemistry steps.

3-47

e The highest mean concentration of Sr-90 occurred at 8eaver Dam Road (collected on 9/9/83) and the highest mean concentration of Sr-89 occurred at the Plymouth County Farm (collected on 5/26/83).

l However, there were no positive measurements made of either Sr-89 or Sr-90, there were only indications of the presence of Sr-90 (activity greater than three times the standard deviation). Station releases for this period exhibited a Sr-89/Sr-90 ratio of about 1/150 and therefore it is unlikely that PNPS-1 is the najor source of the indicator. station activity since the measured Sr-89/Sr-90 was about i

1/10.

In the. case of Cs-137, the highest mean value of concentration

' occurred at Beaver Das Road (2.5 mi - 5). The Cs-137 concentration for Beaver Das Road occurred in early July (collected on 7/8/83).

'The absence of Cs-134 at this location, as well as the other indicator station (Plymouth County Farm), would indicate that the

. primary source of Cs-137 is other than PNPS-1, and was nost likely

dme to fallout f rom previous atmospheric weapons testing.

l l

'llierefore, it is extremely unlikely that there was any environmental

-impact on milk due to the operation of PNPS.

III.M. Veaetation Samples of tuberous and green leafy vegetables were collected at the time of harvest at five locations: Plymouth County Farm (3.5 mi - W), Bridgewater Farm (20 mi - W), the Evans Residence (0.7 mi

- W), the Work Residence (0.6 mi - ESE), and the Whipple Farm (1.5 mi - SSW). The MDC for samples at three of the above locations (the Evans Residence, Work Residence and Whipple Farm) does not appear to have been met. This was due'to an increase in processing time at the Laboratory as a result of a failure to place priority special sensitivity designation on the gamma spectrometry processing forms. The Laboratory has already addressed this situation (YAEL Memo fEL 57/84, dated 2/24/84).

The results of the ERMAP program for this media are presented in Table III-M-1.

The only isotopes observed (other than naturally occurring Ac11t-228 (peak) and K-40) was Be-7 and Cs-137. A positive l

1 measurement of Cs-137 was detected in a vegetation sample from the Evans Residence (ritubarb, collected 9/27/03). The absence of Cs-134 at this location and the fact that measured Cs-137 concentration is about 1,000 times what would be expected at this location based on releases from PNPS-1, strongly indicates that fallout, not PNPS-1, is the primary source of this Cs-137.

Therefore, it is extremely unlikely that there was any environmental impact on vegetation due to the operation of PNPS-1.

III.N. Forace Beef forage is collected from three locations annually: the Plymouth County Fann (3.5 mi - W - Station Number 11), Whitman Farm (21 mi - NW

- Station 21) and Bridgewater Farm (20 mi - W - Station 27). The results of the ERMAP program for the media are presented in Table III-N-1. The following positive measurements were made: Be-7 and Cs-137 at the Plymouth County Farm; Be-7 at the Bridgewater Farm; and, Be-7 at the Whitman Farm. In addition, all. stations had a positive measurement of K-40, and the Plymouth County Farm also had a positive measurement of AcTh-228 (peak).

The only positive measurement of Cs-137. occurred.at-the Plymouth County Farm. The Plymouth County Farm is an indicator station and is located 3.5 miles - W from PNPS-1. The measured Cs-137 concentration is about 1,000 times what would be expected at this location; based on Teleases from PNPS-1. This strongly indicates that fallout from previous atmospheric weapons testing, not PNPS-1, is.the primary source of this l

Cs-137.

Therefore, it is extremely unlikely that there as any environmental impact:en forage due to the operation of PNPS-1.

Results of Boston Edison Inn Situ Gama Spectrometry Soil Analysis for 1982 Introduction In compliance with Bosten Edison's Technical Specifications for radiological in situ gamma spectrometry analyses were performed monitoring at eleven sites of theduring environment, May, Oct'ober and December of 1982. In addition to the gama I

spectrometry, which employs a Ge(Li) "downlooker" detector in accordance with l Reference 1,' measurements were taken with a pressurized ion chamber (PIC) to assess the total . exposure rates, and soil core samples were taken at five of the stations to confirm the in situ results.

At all elev'iin stations, by far the major contributors torthe exposure rate due to soil were naturally occurring radionuclides and Cs-137, which is a result of fallout from weapons testing. A small amount of Co.60 was present in the soil at one site. These results are sumarized in Tables 1-12, and the original data is on pemanent file at the Environmental Laboratory.

Methodology In situ gamma spectrometry was performed at each of'.the eleven locations, along I

with71E" measurements for comparison. When possible, a soil . sample was also taken for laboratory gama analysis.

In situ gama spectrometry is a convenient and efficient technique used to evalHte the radioactive constituents of the soil. Using assumptions concerning the soil composition and distribution of the radionuclide of interest, the exposure rate and activity concentration of that radionuclide can be calculated. This is

' done .using .the spectrum obtained with an unshielded Ge(Li) detector placed above The the ground, tngether with detector specific parameters such as efficiency.

radionuclides of interest are fallout and plant related fission and activation products, as.well as those which occur naturally. In evaluating the activity j concentration and exposure rate for a given radionuclide, a parameter describing depth distribution, s/o, must be evaluated. For naturally occurring radionuclides a value of zero is assumed, implying no increase or decrease in the concentration with soil depth. For radionuclides present only on the surface, such as those from J

I fresh fallout, a value of infinity is used. (This value is also used for calculations of apparent activity concentrations and exposure rates for those radionuclides not found during the peak search.) For iian-made radionuclides found l

in the soil and not believed to be recently deposited, an expatential distribution is assumed with s/o = .206. This value is a good compromise between deep 1

distribution and surface deposition; and laboratory analysis usually confirms that these radionuclides are present througout the first six inches of soil implying a

{ period of migration. This procedure of in, situ gamma spectrometry is explaineu in detail in Reference 2.

The PIC measurement, which includes all components of the exposure rate, not just terrestrial, is used to evaluate how much of the total exposure rate can be explained by the in situ results together with the cosmic contribution. At control

!! stations, away frisiii the plant's influence, the PIC measurement is used to check the t'

in situ results, as one would expect the terrestrial exposure rate, calculated Ts'ing the in-situ methodology, together with the cosmic contribution to closely

~

3 approximate th"iiTIC results.

'j When possible soil core samples are also taken and analyzed at the laboratory to confirm the presence or absence of radionuclides in the soil which have been identified in the in situ analysis. In this way, the source term is identified as ll soil or unknown. Tii the latter case, the in situ calculations are not valid and is results are not reported. In addition, anliTysis of the different core sections aids in defining the depth distribution of the radionuclide.

I f i,

Results Tables 1-11 contain the results from the in situ gama analysis for the eleven si tes. (It should tie noted that in August thTGWe) detector was repaired to remedy increasingly poor resolution. The poor resolution was not a problem in the measurements conducted during May; and prior to analysis of the remaining .three sites, the operating characteristics of the detector were carefully checked with the result that recalibration following the re' pair was dee'ned unnecessary for in sita analysis (Reference 3).) Each table lists the apparent exposure rate anF actTvity concentration for each of thirteen fission and activation . products, as well as for three naturally occurring radionuclides. LLD values were not calculated for nuclides with more than one peak, as in these cases all of the peaks i

found were used to calculate the total exposure rate and activity concentration for i that nuclide (or series). Table 12 contains all positive -in situ results :as well as PIC measurements for comparison.

, With two exceptions, all exposure rates due to activity within the soil are 8

more than 95 percent resul ting from natural radiation. The remainder is almost entirely due to Cs-137 which is considered to be a result'of weapons testing and is found throughout the environment. The first exception is high Cs-137 concentration

. at site 10, resulting in 17 percent of the. total exposure rate due:to soil. The activity concentration for Cs-137 at this site is greater than five . times the average value for the other stations. The most probable explanation for this is that the detector may have been placed over a local accumulation point of debris, and therefore the fallout related Cs-137 was present in a higher than average concentration. It should be noted that sites considerably closer to the plant

  • showed only typical environmental levels of Cs-137, and the high concentration is therefore not likely to be plant related. The second case in which the exposure rate due to soil was more than 5 percent related to fission or activation products,

? was at station 7 where Co-60 was identified during in situ analysis, and confirmed i by Laboratory soil analysis. The activity concentrat' ion was calculated to be 305*7 pCi/kg, assuming a value for a/o equal to -.206, while Laboratory analysis i resulted in a value of 224*13 pCi/kg. The value for a/o is likely .to be greater l than .206, i.e. the distribution of Co-60 was more planar, as it was not found in the 2"-4" core section. This increase in m/c would result in a lower value for

, activity concentration more in line with the Laboratory results. In any case, the

exposure rate due to Co-60 was calculated to be less than 1 uR/hr.

Cobolt-60 was identified at three additional sites, but could not be confirmed by Laboratory soil analysis (there was no core sample submitted for site 00). As the source term was therefore unknown for these sites, the exposure rates which were calculated assuming soil to be the source term, are not valid and were not listed in Table 12. It should also be noted that Zr-95 was detected at two sites at levels at or below LLD, but these results could not be confirmed by soil analysis at the Laboratory.

The PIC measurements agreed well with the in situ results, when a cosmic component of 3.6 uR/hr (Reference 4) was added! with a few notable exceptions.

Sites 00, 07 and 08 showed relatively high PIC measurements which could not be explained with the Ge(Li) results. These sites are all within 0.15 miles of the l

plant so that the higher than background exposure rates were most likely a result

.of.some source term other than soil.

The 200 pCi/Kgm r:dioccoium "cetirn lev:1* is based on eciculations which i,

. - --- showed that if r:diocccium from picat ralcacco rccched thio Icvel, Tha plutonium could possibly appear at levels. of potential interact.*

esiculactens also showed that the dose delivered from these levels of plutonium would not be a significant portion of the total dose attributable to liquid effluents.

The program was also designed to be consistent, wherever applicable with ,

Regulatory Guide 4.3 (Issued for comment December 1975). The following ,

exceptions to the generic recommendations stated in Regulatory Guide 4.8 i

are justified due to site specific considerations:

1. m required detection capability for I-131 in milk 'is about twice the value suggested in Regulatory Guide 4.8. The justi-h

' fication for the bisher value is presented in the second paragraph of this section. This is a conservative estiaste of the capability -

of thq milk surveillance program to detect concentrations at the appropriate annual dose level since the annual dose is p a portional to the annual averste concentration in silk. The detection limit for a group of samples is less than that for a single sample and is inversely proportional to the square root of the number of samples. The conser-vatism in this case is approximately allT, or about a factor of J.

2. Air particulates are not analyzed for radiostrontium.

The program instead calls for this analysis in milk sangles. This is justified because the air-cow-milk exposure pathway can be better non-itored at Pilgrim after the very low level selaases of radiostrane4i-ste reconcentrated in cow's milk (Inf. 1).

3. Sails and sediments are not routinely analysed for Sr-90, but rather the analysis is done se a contingency basis. h rationale behind this

' is that gr-90 will not contr h ts to long-term radionne14d= % %

- until the more abi=d==e gamma sandsting nuclides appear in relatively large concentrations. Both Items 2 and 3 refleet the fact that in 31s

+ years of operation, Pilgria Station liquid releases of Sr-90 have amounted to only 1/1000 of the Sr-90 inventory in Cape Cod Bay water -

(from weapons testing fallout) and about 4/1000,000 of the direct deposi-tian on the Bay. Also, gaseous releases of Sr-90 have been only 1/200,000 of the terrestrial Sr-90 inventary within five =f1== of the station (Ref.1).

,r.-v. late l: 4. Sarveys are conducted annually, if necessary, to determina

' locations for asapling of leafy vegetables and milk. The objective of these surveys is to ensure that the environmental samples are represen-tative of realistic food chain pathways, considering local conditions.

Results of the monitoring program will be used as "beschestks" to verify calculational models used to predict the consequences of affluent releases from the station. The models can then be engloyed to predict doses attributable to radiation deposition at any other location of interest.

The combination of monitoring results and calculationsalmodel predictions is a practical method of demonstrating compliance with 10CTR50 Appendix I.

This approach does not require (nor is it always practical) that environ-asetal media always be sampled from the " worst case" locations: although sensitivity of the monitoring results might be improved by sampling free locations which are reasonably close to "morst case" conditisms.

1 l Verificatism of the sopropriate milk sampling locations on an annual i basis is satisfactory as there are very few locations suitable for the

.g- grazing of dairy herds in the vicinity of the plant (gaf. 2). This i

situation askas it unlikely the location of the nearest dairy herd (3.5.ailes-U) will change.
3. Annus1 ---14=g of beef forage (in place of beef) is adequate because .

beef cattle are not raised commercially to the vicinity of the site.

. However, dairy cows from the Plymouth County Farm are periodically sold .

for beef. Feed (hay) from this location will be sampled to monitor this potential pathuey for ingestion of radioactivity. If beef cattle feeding

~

sa local forage are found'at locations closer .to the site, forage i samples from the c2aser 1ae=e4a= uill replace zhe sample from the I cammey Yarm.

6. Soundueter flow st:the plant site is into Cape Cod Eey; therefore,

_ terrestrial monitoring of groundwater is not.4=e1 Mad in this program.

7. Poultry N T14== is not r Im_4 because poultry in ylymouth County feed a2most ancimitusly na imported grain-and are,asually raised under mhaltar.

. B. Tia2d asmana fmi- surveys are-tenducted to sonitor indioactivity in 4o11.1a 11em of 2aboratory analysis of soil semp2as. Se technique has several advantages over laboratory analysis. First, analysis can be

, performed on the same p3st of'3and from survey to survey, and radio-activity bui2d-op at the location.cma be accurately determined. Secondly, gamma suposure Tata is determined dixectly from this technique: hence m '* e with IDCFR50 Appendix I amvela can be. investigated directly zather than dadirectly through sail sampling.

1983 GARDEN & MILK PRODUCING ANIMAL CENSUS As required by PNPS Environmental Technical Specifications, the 1983 Garden & Milk-Producing Animal Census was conducted on 9/16/83 in a street by street search of the area within 1 mile of PNPS.

The existence of gardens near the site boundaries of 0.7 miles West and 0.6 miles ESE was confirmed. These gardens are the closest and largest in the near vicinity (1 mile) of PNPS, and are less than 500 sq. ft. They do represent conservative garden locations for sampling analysis and dose calculation. With the assistance of Mr. Robert Tis, vegetation samples were collected from three locations on 9/27/83. Only two of these locations are within one mile of PNPS. A sample of squash leaves and chinese cabbage was collected from the J. Work Residence (0.6 miles ESE) of John Alden Road; thubbarb was obtained from the Lyoyd-Evans residence (0.7 miles West) on Gate Road; and, lettuce was collected from the Whipple Farm (1.5 miles SSW) off Daten Road.

In addition, no cows or goats or structures which would indicate the C., presence of such animals within 1 inile of PNPS were found. The Plymouth Animal Inspector forwarded a listing of the 1983 Census as well as a listing of the 1983 Barn Check. The location of cows and goats in the area are as follows:
