I-A INTRODUCTION The Power Authority of the State of New York (PASNY) is the owner and licensee of the James A. FitzPatrick Nuclear Pcwer Plant (JAFNPP) which is located on the eastern portion of the Nine Mile Point promontory I approximately one-half mile due east of the Niagara Mohawk Power Corporation (NMPC) Nine Mile Point Nuclear Station (NMPNPS). The NMPNPS unit #1 is located on the most western portion of the site and is a boiling water reactor with a design capacity of 610 MWe. The NMPNPS has been in commercial operation since the fall of 1969 Located between the JAFNPP and NMPNPS, Nine Mlle Point unit #2 is under construction. NMPNPS unit #2 will have generation capacity of 1100 MWe and is expected to be completed in 1984. I The JAFNPP is a boiling water reactor with a power output of 820 MWe (net). Initial fuel loading of the reactor core was completed in November of 1974. Ini tial criticality was achieved in late November 1974. The site is located on the southern shore of Lake Ontario in Oswego County, New York, approximately seven miles northeast of the ci ty of Oswego, New York. Syracuse, New York is the largest metropolitan center I in the area and is located forty milt.. to the south of the site. area consists of partially wooded land and shoreline. The land adjacent The to the site is used mainly for recreational and residential purposes. For many miles to the west, east and south the country is characterized by rolling terrain rising gently up from the lake, composed mainly of glacial deposits. Approximately 34 percent of the land area in Oswego County is devoted to farming. The Radiological Environmental Monitoring Program for the FitzPatrick Plant is a site program with responsibility for the program shared by the Power Authority and Niagara Mohawk. Similar Technical Specifications for radiological monitoring of the environment allows for majority of the sampling and analysis to be a joint undertaking. Data generated by I the program is shared by the two facilities wi th review and publication of the data undertaken through each organization. This report is submitted in accordance with Section 5.6.1 of Appendix B, to OPR-59, Docket 50-333 Environmental reports of this nature have been compiled and submitted in semi-annual and annual reports since 1974. This report contains data from samples representing the period from January 1, 1980 to December 31, 1980. I

I : i I l-B PROGRAM OBJECTIVES The objectives of the Radiological Environmental Monitoring Program are as follows: To determine and evaluate the effects of plant operation on I 1. the environs and to verify the effectiveness of the controls on radioactive material sources.

2. To monitor and evaluate natural radiation levels in the environs of the JAFNPP site.

3 To meet the requirements of applicable state and federal regulatory guides and limits.

4. To provide in % mation by which the general public can evaluate I the environmental aspects of nuclear power using data which is factual and unbiased.

Il PROGRAM IMPLEMENTATION AND DESIGN To achieve the objectives listed in Section 1-B, sampling and analysis are performed as outlined in Tables 1 and 2 in this Section. The sample collections for the radiological program are performed by two groups. Texas Instruments incorporated, Ecological Services Branch (TIES) performs much of the environmental sampling. TIES was responsible for performing the 1980 Nine Mlle Point Aquatic Ecology Study at the site which is required by Section 4.1, Appendix B of DPR-59 The staff required by TIES to perform this study is used to perform the terrestrial plant and remaining terrestrial sampling is performed jointly by the JAFNPP and NMPNPS staffs.

1. SAMPLE COLLECTION METHODOLOGY A. Lake Water (surface water)

The two indicator stations are the respective inlet canals at JAFNPP and NMPNPS. These samples are composited using continuously running pumps which discharge into large holding tanks. The control station sample is collected from the city of Oswe-a water intake. The sample is drawn from the intake prior to treatment and is composited in a large sample bottle. Quarterly composite samples are made up from proportional aliquotes of monthly samples. - B. Air Particulate / lodine The air particulate glass fiber filters are approximately two inches in diameter and are placed in sample holders in the intake line of a vacuum sampler. Directly down stream from the particulate filter i s a 2 x 1 inch charcoal cartridge used to absorb airborne radiciodine. The samplers run continuously l and the charcoal cartridges and particulate filters are changed I on a weekly basis. lg The particulate filters are composited on a monthly basis by l g location (of f-si te, on-si te) af ter being counted for gross beta activity. l The air sampling stations are located in two rings surrounding I the site. The on-site locations ring the terrestrial area around the plants inside the site boundary. l 3 t L

B. Ai r Particulate / Iodine (Continued) The on-site sampling network is composed of nine stations. The off-site air mon!toring locations range six to 17 miles f rom the si te and is composed of six stations. Air monitoring locations are shown on Figures Vll-I, and VIl-2. C. Milk During 1980 milk samples were collected from six locations. I Five of these locations are considered Indicator samples and the sixth is used as a control sample. Milk samples are collected in polyetnylene bottles from the bulk storage tank I at each sampled farm. Before the sample is drawn the tank contents are agitated from three to five minutes to assure a homogenous mixture of milk and butterfat. Two gallons are collected during the first week of each month from each of the I five farms. An additional one gallon is collected from each farm at mid-month to make up the second half of the monthly composite. The complete composite is made up from one gallon collected during the first week of the month and one gallon from the mid-month collection. The samples are frozen and shipped to the analytical contractor within 24 hours of collection in insulated shipping containers. The milk sampling locations I are found on Figure Vil-4. D. Meat, Poul try and Eggs Semi-annua 6ly one kilogram of meat is collected from locations within a 10 mile radius of the site. Weekly phone calls are made to the local slaughter houses to determine availability of slaughtered live stock from within the sampling area. Whenever possible meat samples are collected from locations previously used. Semi-annually one kilogram of poultry a9d one kilogram of eggs l are collected from each of three locatiors within a 10 mile l radius of the site. Attempts are made to collect poultry and i eggs at the same time as the meat samples. The poultry ano eggs are frozen and shipped in insulated containers. Whenever E possible samples are obtained from previously sampled farms E (see Figure Vil-5). F. Human Food Croos Human food crops are collected durir.g the late summer harvest season at locations previously sampled, if available. One kilogram each, of the two types of f rui ts and/or vegetables I from each of the three locations wi thin a ten mile radius of the site are collected. The types of fruits and vegetables sampled depends on what is locally available at the time of I collection. Attempts are made to collect at least one broad leaf type vegetable from each location. The fruits and vegetables are chilled prior to shipping and shipped fresh in insulated ( 3 containers (see Figure Vll-5). 1

G. Soll Samples Soil samples are required once every three years. Samples I were collected during 1980. Soll samples were taken at each of the 15 air monitoring stations (see Figures Vll-1 and Vll-2). H. Fish Samples Available fish species are removed from the Nine Mile Point Aquatic Ecology Study Monitoring collections during the spring I and fall collection periods. Samples are collected from a combination of the four on-site sample transects and one off-site sample transect (see Figure Vll-6). Available species are selected under the following guidelines:

1. 0.5 to I kilogram of edible portion only of a maximum of 3 species per location.

2. Samples composed of more than one kilogram of single species from the same location are divided into samples of I kilogram each prior to shipping. A maximum of three samples per species per location are used. Weight of samples are the edible portions only.

Selected fish samples are frozen immediately after collection and segregated by species and location. Samples are shipped frozen within two weeks in insulated containers.

1. Gammarus Gammarus (f resh water shrimp) samples are collected by TIES I personnel during the spring and fall season from two on-site locations and from one of f-site location. A 0.5 m Tucker Trawl (333 u) 1.0 m Hensen Het (571 u), boxtraps and artificial I substrates are used to collect samples. The Gammarus samples are removed f rom the sampling gear, frozen and shipped to the analytical contractor in Insulated shipping containers.

I J. Mollusks During the spring and fall seasons at two on-site and one off-I site location benthic samples are ollected. The mollusks are collected by divers and sorted. The tissue is removed from the shell, frozen and shipped for analysis in insulated containers. l K. Bottom Sediments l l One kilogram of bottom sediment sample is collected at two en-l site locations and one off-site location. Samples are collected I at the same time and location as the mollusk samoles, where j possible, by a diver. The samoles are placed in plastic bags, sealed and shipped for analysis in insulated containers. I lI 1 s

I I L. Periphyton Periphyton samples are collected in the spring and fall season f rom two on-site locations and one of f-site location. Periphyton is collected from natural and/or artificial substrates (plexiglass slides). The periphyton is scraped from the substrates into vials, labeled, frozen and shipped in insulated containers for I of f-si te analysis. M. TLD (direct radiation) I Thermoluminescent dosimeters (TLD's) are used to measure direct radiation in the JAF/NMP-1 environment. The TLD l l stations are placed around the site using a three zone division. I The first group of TLD's are located within the site boundary and are called "on-site" TLD's. The second set of TLD's are called " site boundary" stations and are located at approximately I I the site perimeter. The third division of TLD stations are the "off-site" stations, located at the off-site air monitoring stations. I Each TLD set is made up of two CaSO4 dosimeters (two chips per dosimeter), sealed in a polyethylene package to insure dosimeter i l i n teg ri ty. The TLD packages are further protected by pincement I in plexiglass " birdhouses", or by tape sealing to supporting surfaces. The dosimeters are collected, replaced and evaluated on a quarterly basis. N. Special Samples 'E Special Environmental Radiological Samples were also analyzed E by RMC. Several additional sample media were collected during the 1980 sample period to help in evaluating and interpreting the milk data which was compiled in 1979 and 1980. lI l The following additional sample media were collected during 1980:

1. Pasture Soil - Soil samples were collected once during I

1980 from each of the six milk sample locations. Each sample was analyzed for gamma emmiters using gamma spectra l analysis.

2. Pasture Grass - Pasture grass was collected once in 1980, during the re ture season, in conjunction with the pasture lE Ig soil collect.ons. Each sample was analyzed for gamma emitters using gamma spectral analysis.

lI lI e

I 3, Fodder Crops - Samples of fodder crop including hay, haylage, corn silage and grain were collected during 1980. Fodder crop samples were collected at each of the I six milk sample locations. The specific type of sample collected was dependent upon which types of feed were used by each farm. Attempts were made to sample each month during the winter when the dairy herd was existing almost entirely on supplementary feed. Collections were also made so that a sample was obtained I from each harvest series for hay, haylage and corn silage or from each new shipment of grain received by the farm. The collection program was designed to sample the supplementary diet of dairy herds at the milk sample I locations. Each sample was analyzed for gar.vna emitters using gamma spectra analysis.

2. ANALYSIS PERFORMED The environmental radiological surveillance sample analysis is performed by Radiation Management Corporation (RMC) except for the air particulate gross beta samples and lodine cartridges which are counted on site. These two sample media are counted on site to facilitate the compositing of the air particulate filters af ter gross beta analysis and the timely analysis of charcoal cartridge for lodine-131.

I C 3 CHANGES AND ADDITIONS TO THE 1980 SAMPLE PROGRAM A. Early in 1980, the owner of the daily farm designated as location number 25 in this report, sold his dairy herd and is I no longer producing milk on a commercial basis. Prior to the selling of the herd, this farm was a routine milk sample location and was considered to be an important sample point due to its close proximity to the site. The farmer at location number 25, upon selling his herd, 1 E retained one milk cow for production of milk for his personal . use. The single animal was not sufficient to maintain milk lE l production on a level which was suitable to supply the volumes necessary for the monthly sampling requirements. To avoid noncompliance with the plant Environmental Technical Specifi-cations, due to inadequate sample volumes, this farm was deleted.as one of the required milk sample locations. Because of the important location of farm number 25 and the l large data base already in existance for this location, an ef fort was made to continue sampling this farm on a routine I basis throughout the normal sample period. As noted in Table 16, the August and September 1980 samples were collected several days later than the other milk locations due to I insufficient volume being available at the scheduled collection time. I ,

i I B. As a result of the loss of location number 25 as a reliable milk semple location, a replacement farm was added to keep the i number of milk locations in compliance with the requirements of Environmental Technical Specifications. The new milk I sample location is approximately seven miles southeast of the site and is identified as location number 12 in this report. 1 C. On June 3, 1980, seven additional environmental TLD stations were added. These new TLD locations are described on Table 14 and designated as locations 43 through 49 D. Mi!k sample location number 8, which was sampled in 1979, was deleted from the 1980 sample program at the request of the farmer. I I I . I I I I

SUMMARY

AND CONCLUSIONS The resul ts of the 1980 Radiological Envi ronmental Moni toring Program must be put into perspective considering the natural processes of the environment and the aggregate of past data. Several factors must be considered in the course of radiological data evaluation and interpre-tation. First, it must be recognized that our environment includes a broad inventory of natural background radiation of primordial and daily origin wnich is in a constant state of flux, influenced by a myriad of phenomena, from solar activity to meterlogical conditions. Secondly, the detonation of man-made nuclear devices in the atmosphere has resulted in an extensive array of radioactive isotopes in the atmosphere and on the surface of the Earth from global fallout. Section VI, titled HISTORICAL DATA, contains sample statistics from previous environmental sampling. In the process of determining the impact (or lack of impact) of the plant on the environment, the scrutiny of past analytical data can be a tool by which trends can be discerned. The interpretation of historical data in this report was performed to a limited degree. Because of the constant change in analytical sensi ' tivi ties, as state-of-the-art detection capabili ties improve, data comparisons become difficult. Minimum detection capabilities for the 1969 and 1974 analyses of environmental data would be considered anomalies by 1980 analytical standards. A. LAKE PROGRAM Tables 3 through 8 list the analytical results for the aquatic media sampled during the 1980 sampling program. Aquatic samples were obtained at a combination of four on-si te locations. The transect designations used for the on-site sampling are NMPW (01), NMPP (02), JAF (03) and NMPE (04). Due to limited availability of certain required sample media, samples could not be obtained consistently at each of the same on-site transects sampled for other media. Of f-si te samples were collected in the vicini ty of the Oswego Harbor 0FF-SITE. (00) . 74

1. Periphyton Samples - Table 1 The collection and analysis of periphyton samples was performed twice during the 1980 program.

Periphyton is an abundant fresh water algae found throughout;the Great Lakes. Periphyton is a single celled organism which colonizes the natural and artificial substrates found in shore and near shore waters. Colonies of periphyton are found from the shore zone to

water depths which can be suf ficiently penetrated by sunlight to support photosynthesis. Periphyton is dependent on sunlight and inorganic materials found in lake water to support life. It is locally identified as the slippery green-brown coating found on the near-shore rocks. Periphyton is used as an Indicator organism to help evaluate the possible effects of plant operation on the local aquatic environment.

The first collection of periphyton samples was completed on June 12, 1980 and the second collection was completed on August 4, 1980. The results of gamma spectral analysis of periphyton samples are presented in Table 1, Section IV. Analytical results show the presence of Mn-54, Co-60, Cs-134 and Cs-137. These isotopes can be considered to be a result of plant operation. In addition, the presence of Be-7, K-40, Ra-226, and Th-232 was detected between the two sample collections. This second group of isotopes are naturally occurring radionuclides and are found in many living organisms. Cs-137 requires special consideration a's this isotope of cesium can be the result of plant operation, but is also a very common constituent 3 of the natural background as a result of the many atmospheric g nuclear tests conducted in the past. The first set of periphyton samples collected on June 12, 1980 yielded detectable concentrations of Mn-54, Co-60 and Cs-137 These plant related isotopes ranged from 0.008 pCi/g (wet) for Co-60 to 0.14 pCi/g (wet) for Cs-137 The isotope detected in the most significant quantity was Cs-137 The level of Cs-137 detected at the indicator sample stations is likely to be the result of fallout from a past atmospheric nuclear test with a contribution from plant effluents. The presence of Cs-137 was also found at the control station for this same sample period which is a strong Indication that at least a portion of Cs-137 detected at the indicator stations was the result of atmospheric fallout, which was accumulated in the periphyton organisms through biological processes. 75 I
g The second set of periphyton samples collected during 1980 showed an increase in Cs-137 in the samples taken at the control and I indicator sample locations. A general increase of concentrations for plant related isotopes was noted. An increase in concen-trations was also so observed for naturally occurring isotopes, particularly Be-7 and K-40, between the first and second collections. This increase may possibly be attributed to the higher metabolic and growth rates of the periphyton organism between the first and second collections (June to October) as primary production is highest in the latter summer months and not from an increase in radionuclide concentrations in the lake in the vicinity of the site. Lake water gamma isotopic analysis of samples taken during this same sample period showed no positive identification of plant related radioisotopes or an increase in the concentrations of naturally occurring radioisotopes. Liquid effluents released from the plant were significantly lower in the second half of 1980 when compaired to the first six months. The isotope detected in the most significant quantity was Co-60 which has a bioaccumulation f actor of 200 pCi/Kg per pCi/1. Each of the plant related isotopes detected in the 1980 samples were trace concentrations with the probable specific source being I past and present plant liquid effluent releases. A dose to man calculation from the levels of activity found in lake periphyton samples in the vicinity of the plant is difficult to perform as these organisms are not in the human food chain. For the purpose of illustration, a dose calculation can be made using g some unrealistic assumptions. If an adult were to consume 64 l 3 Kg/ year of periphyton (an amount equal to the maximum annual adult l consumption of green leafy vegetables) the dose from the indicator station Cs-137 concentration of 0.14 pCl/g (wet) would be 0.64 I mrem / year to the whole body. The resulting dose of the indicator Co-60 concentration of 0.15 pCi/g would be 0.045 mrem / year to the whole body. The total hypothetical whole body dose from the Co-60 and Cs-137 concentrations would be equal to 0.69 mrem / year at the indicator stations compared to 0.14 mrem / year to the whole body l from the Cs-137 concentration at the control station. The whole body dose of 0.69 mrem / year is very low with respect to natural background radiation and the changes in the levels of background radiation. A review of past data shows Cs-137 levels in periphyton samples to be lower in 1980 than in 1978 and 1979 and significantly lower than levels detected from 1974 to 1976 (see section vi) . Co-60 concen-trations in periphyton samples showed a similar trend as Cs-137 concentrations. 1980 results were slightly lower than concen-trations detected in 1979 Ce-144 which was detected in 1977 through 1979 was not detected in 1980. Past levels of Cs-137, Co-60 and Ce-144 are presented in graphic form in section Vll. 76

2. Bottom Sediment - Table 2 Bottom sediment samples were collected twice during the 1980 sampling program. Gamma spectral and strontium -90 analysis were performed on each of the samples and the results are presented in Table 2.

For 1980, samples were collected in June and October, with the Oswego harbor (of f-si te/00) serving as the control and transects 01 g (Nine Mile Point West) and 02 (Nine Mile Point Plant) serving as I the indicator stations. A review of the sample results show that Cs-137 was the most abundant radioisotope occurring in this sample medium. The presence of Co-60 and Sr-90 were also detected in two of four on-site samples collected with a maximum Co-60 concen-tration of 0.35 pCi/g (dry) at the 01 transect and a maximum Sr-90 concentration of 0.011 pCl/g (dry) at the 02 transect. The presence of Cs-137 in the sediment samples can be attributed primarily to the accumulation of fallout in the environment as a result of the detonation of nuclear devices in the atmosphere. This fact is easily illustrated by the presence of Cs-137 in the control station sample. THe concentration of Cs-137 in the control samples exceeded that of the indicator sample for the series of samples collected in October and was the second h*ghest sample concentration in the June collection. Two of the indicator samples contained detectable levels of Co-60 which ranged from 0 35 to 0.?1 pci/g (dry). The presence of Co-60 in sediment samples is due to the deposit lon of plant effluents. The total liquid release to the lake was 0.803 Cl for Co-60 and 0.106 Ci for Cs-137 in 1980. All liquid effluents were within allowable limits. Strontium-90 was also detected in the aquatic sediment samples collected and analyzed for the 1980 program. As with Cs-137, the presenca of Sr-90 in sediment is a direct result of fallout from atmospheric nuclear tests. The concentration of Sr-90 at the control station was almost ten times the concentration of mean indicator concentration in the June sample collection . A possible explanation for the disproportionatly high concentration of Sr-90 at the off-site station is the difference in the physical and chemical makeup of the sediment types or the fact that the control station is near the inlet of a river with a large drainage basin which would result in an accumulation of sediments containing Sr-90 leached from the drainage basin and deposi ted as the river meets the lake. The dose to man cannot be directly calculated for lake bottom sediment as bottom sediment is not accessible to man and the radio-activity found in the sediment is shielded by the overlaying water column. In addition, lake sediment is not a major component of the aquatic food chain due partially to the low organic content of the sediment and secondly because much of the material absorbed by organisms that are primary tc the lake sediment habitat is not passed up through the food chain to higher life forms. This mechanism 77
can be illustrated by the presence of small quantities of Co-60 in periphyton and sediment samples, but the general lack of Co-60 in the fish samples collected in the vicinity of the plant. To illustrate the impact of radioactivity in sediment samples with respect to the dose to man concept, the unlikely assumption could I be made that lake bottom sediment could at some future time find itswaytothesurfaceandbecomeshorejinesediment. Assuming that the densi ty of se; . ment is 40 Kg/m (dry) and an average residence time on the shore of 47 hours per year for a teenager, I the annual dose rate from a Cs-137 concentration of 0.94 pCi/g (dry) would be 0.0074 mrem / year whole body dose and the dose from the Co-60 concentration of 0 35 pC1/g (dry) would be equal to 0.011 I mrem / year whole body, resulting in a total dose of 0.018 mrem / year whole body. This improbable dose can be considered minimal, if not insignificant when compared wi'h natural background radiation levels. A review of past data shows the levels of Cs-137 to be randomly distributed from 1974 to 1980 with a general trend downward in concentrations, wi th a maximum of 2.45 pCl/g (dry) in 1976 to a low of 0 34 pCi/g (dry) in 1980 for the indicator stations. The levels of Co-60 in the indicator samples were trending down with the 1980 mean value less than 1978 and 1979 Past concentration levels for Co-60 and Cs-137 are presented in graphic form in Section Vll. 3 Mollusk Samples - Table 3 The results of Mollusk supling and analyses are presented in Table 3 The sampling effort fer mollusk in the vicinity of the Nine Mile Point promontory is often of limited success in terms of sample volume collected. The 1980 sample collections were no exception. In cases where sample volumes were low, three distinct attempts were made at each tample location to collect sufficient I amounts of mollusks to perform analysis of suf ficient sensi tivity. The main reason for poor sample yields is that the lake bottom configuration off shore from the site is mainly bedrock, with sediment of insufficient depth to sustain an extensive mollusk population. Mollusk samples were successfully collected at the control and the 01 and 02 sample transects. No mollusks were collected at the 03 (JAF) sample transect. The results of the isotopic analysis of the moliusk tissue showed the presence of two plant related isotopes and two naturally occurring isotopes. The two naturally occurring isotopes detected were Ra-226 and Sr-90. Sr-90 is considered a background isotope because its origin is not related to plant operation and can be traced to the i detonation of atmospheric nuclear devices. Detectable levels of lg5 Sr-90 were measured in each of the mollusk samples collected in l 1980 both at the control and indicator stations. The presence of Sr-90 in all the mollusk samples collected was also true in 1979 l Strontium-90 concentrations ranged f rom 0.033 pCi/g (wet) to l l
1 0.14 pCi/g (wet) with the control station mean equal to 0.07 pCi/g l 4 (wet) and the indicator station mean equal to 0.11 pCi/g (wet). El Sr-90 has a radioactive half life of twenty-eight (28) years which ! will make it detectable in the environment for many years. i Two radionuclides were detected in the 1980 mollusk samples that can be attributed to the operation of the plant. Manganese-54 was measured in three of the four indicator samples collected with concentrations ranging f rom 0.'l pC1/g (wet) to 0.03 pCi/g (wet). j Cobalt-60 was detected in one indicator sample wi th a concentration of 0.03 pCi/g (wet). A possible explanation for the disproportinate concentrations of Mn-54 could be the very high bioaccumulation factor for fresh water mollusks of 90,000 pCi/Kg per PCl/1, compared . to 200 pCi/Kg per pCi/1 for Co-60. Such a high bicaccumulation - factor would result in a rapid concentration of manganese activity in the mollusk that are indigenous to the of f shore area of the site. The total release of Mn-54 and Co-60 via liculd ef fluent g from the FitzPatrick Plant for the period of January 1,1980 to December 31, 1980 was 0.455 Ci for Mn-54 and 0.803 Ci for Co-60. 3 Discharge dilution flow for this same time period was 6.55 E+11 liters. Fresh water mollusks found in the vicinity of Nine Mile Point are not consumed by humans and are considered to be in the focd chain to a limited degree. Because fresh water mollusk are not considered E edible, no estimate of the possible dose contribution to man f rom E their use as a food, can be made. A dose estimate can be made using substituted parameters for the purpose of putting into perspec- g tive the possible significance of the Mn-54 ani co-60 concentrations g detected in the mollusk samples. Using the average individual consumption of seafood of 1.0 Kg/ year for an adult, the dose result-Ing from ingestion would be 0.0001 mrem / year to the whole body and 0.0015 mrem / year to the gastrointestinal tract for the Mn-54 concen-tration of 0.11 pCl/g (wet). The dose resulting from a Co-60 concentration of 0.03 pCi/g (wet) would be 0.00014 mrem / year to the whole body and 0.0012 mrem / year to the gastrointestinal tract. The i maximum dose received f rom consuming 1.0 Kg of f resh water mollusk in a years time would be 0.00024 mrem / year to the whole body and 0.0027 mrem / year to the gastrointestinal tract. The dose received ! by man is extremely low as calculated above and in reality would be ! zero because the species is inedible. I i l l I I l l l 79 I
I i i l i The levels of Co-60 and Mn-54 show a significant drop from the 1976 I levels and were less than the mean value for the indicator stations in 1979 Sr-90 levels have remained constant since 1974 due to the l long half life of the isotope and recent reductions of atmospheric I testing. Graphs of previous mollusk sample results for Co-60, Mn-54 and Sr-90 are presented in Section Vll. Also found in Section Vil is a physical description of the lake botton in the vicinity of Nine Mile Point.

4. Gammarus - Table 4 Gammarus are benthic or demersal dwelling organisms found in the general vicinity of Nine Mile Point. They are generally confined to natural substrates such as rock debris and areas of cladophora I g row t h . Gammarus are omnivorous scavengers and are shrimp like in appearance. The major predator of gammarus is the fish population in the area which are considered to be at the top of the aquatic food chain. Gammarus samples were collected twice during the 1980 I sample program. The first gammarus collection in June yleided biomasses of 5, 10, and 2 grams at the off-site (00), NMPP (02) and FitzPatrick (03) transects, respectively. The August sampling I ef fort yielded higher sample volumes of 39 grams at the off-site (00) transect, 45 grams at the NMPP (02) transect and 57 grams at the FitzPatrick (03) transect. Three collection attempts were made at each location using a variety of sampling methods. The limited I sample success is similar to that experienced in previous years.

It should be noted that gammarus are normally less than 10 mm in size and require a large number to obtain a biomass of I gram of sample. As a result of the small sample size, sensitivity of the gamma spectral analysis was low but data was at an acceptable level I considering the sample size. Sr-89 analysis was also affected by the small sample size. LLD values ranged from a low of 0.5 pCi/g (wet) to a high of 3.0 pCi/g (wet) in the FitzPatrick (03) indicator sample for June. The analysis of gammarus samples detected the presence of only Sr-

90. This isotope which is considered to be the result of past I atmospheric nuclear testing was identified in one control sample and three indicator samples. Gamma spectral results reported no

' positive identification of possible plant related isotopes. Historical gammarus data shows a general reduction in isotope concentrations detected in earlier samples. No strong trends can be determined since the data base is not extensive due to routine difficulty in collecting sufficient samples for high sensitivity analysis. l 1 l l l l l so
I 5 Fish - Table 5 A total of eighteen (18) fish samples were collected from Lake Ontario in 1980. Samples were collected in the spring season (May, g 1980) and the fall season (November,1980). Collections are made E utilizing gill nets at one off-site location greater than five miles from the site (Oswego Harbor area) and at two on-site locations (in the vicinity of Nine Mile Point (02) and FitzPatrick (03). The l W Oswego Harbor samples serve as control sample while the NMP and JAF samples serve as indicator samples. Samples were analyzed for gamma emitters, Sr-89 and Sr-90. Analysis of the 1980 samples indicate no detectable impact from plant operation. Detectable nuclides included Sr-89, Sr-90, Cs-137 and K-40. Detection of these nuclides were noted at control as well as indicator locations: There were not statistically signif-Icant differences in concentrations of Sr-89, Sr-90 or Cs-137 at the indicator locations when compared to the control location. The E presence of these nuclides of all three locations is an indication 3 of weapons testing influences. Sr-89 was detected at the off-site location and at the Nine Mile Point location. The concentration at the off-site location was higher than at the NMP location. Sr-89 at the JAF location was not detectable. Sr-90 was detected in twelve of the eighteen samples. l Results from the indicator samples were not statistically signif- E icant from the control sample: Cs-137 was detected in all eighteen samples. Again, indicator sample results were not statistically significant from the control sample result. K-40 is a naturally occuring nuclide and is not related to power plant operation. As expected, Indicator and control results are not statistically different. Review of past data indicates no increases of Sr-89, Sr-90, or cs-137 levels and infact, concentrations of Sr-89, Sr-90 and Cs-137 E indicate tne means are decreasing. This is most probably the g result of natural decay and the incorporation of these nuclides with organic and inorganic substances through ecological cycling. The radiochemical analyses of fish samples are important since fish represent the highest significant trophic level in the aquatic system. In the event that the site would be having an effect on the associated aquatic system, the radionuclide concentrations in fish would be detectable through nutrient concentration from the primary and secondary trophic levels. Also notable is the radio-nuclide concentrations in the fish species, white sucker. These fish are typically bottom feeders unlike the peren species which l 5 are predatory. The data demonstrates that there is no buildup of plant-related nuclides in the natural lake substrates in the vicinity of.the site based on the result of fish sample analysis for both bottom feeders and predators. 81 I
I I Lake Ontario fish are considered an important food source by many people thereby placing fish in the human food chain. Based on the importance of fish in the local diet, a reasonable estimate of the I dose to man can be calculated. Assuming that the average adult consumes 6.9 Kg of fish per year and the fish contain a maximum concentration of 0.11 pCl/g (wet) of Cs-137 and 0.013 pC1/g (wet) of Sr-90, the calculated dose to man would be a total of 0.22 mrem / year to the whole body and 0.74 mrem / year to the bone. If the amount of fish consumed were raised to the estimated maximum of 21 I Kg/ year, the resulting dose would be equal to 0.67 mrem / year to the whole body and 2.25 mrem / year to the bone. The dose to man resulting from the consumption of fish contaminated by radionuclides resulting f rom past nuclear weapons test is many times the dose f rom any of I the other sample media analyzed which can be considered to be plant related. I The Cs-137 levels in fish are consistent with levels measured in 1978 and 1979 The last three years show a significant decrease in the Cs-137 from the levels of 1975 and 1976. Sr-90 levels also show a similar trend of significant reductions in concentrations I from samples taken in 1974 and 1976. The measured concentrations of Sr-90 in the 1980 samples show a slight decrease from 1979 values. Cs-137 and Sr-90 concentrations have been graphed and are found in Section Vll.

6. Lake Water - Tables 6, 7 and 8 Lake Water samples are analyzed for gross beta activity. Tritium, strontium 69, strontium 90 and gamma emitters.

I The analytical results for -he 1980 lake water sample program showed no evidence of plant related isotope buildup in the lake water in the vicini ty of the ti te. The gross beta activity was i g comparable to analytical results for 1978 and 1979 The gross beta i 3 activity for 1980 was significantly lower than 1976 and 1977 The I reduction in gross beta activity, since 1974 is primarily the l result of improved analytical procedures and equipment and not I changes in plant operation. There were not significant changes in l gross beta activity on a monthly basis for 1980. Tritium (3 H) is a a tura'iv occurrin9 raoioactive isotope of E g hydrogen which is produced in the upper atmosphere by cosmic rad *ation. The analysis of lake water samples for the 1980 sample period showed no abnormali ties wi th respect to the levels of tritium l l measured in the lake water. The level of tritium has remained constant since 1974 wi th only slight variations. The fact that tritium is naturally occurring accounts for the background levels in the lake varying slightly from year to year. I . 82 1 I
1 1 Strontium-90 activity was detected in eight (8) of twelve (12) quarterly samples required by the plant's Technical Specifications. Both the on-site and the off-site sample locations showed measurable levels of Sr-90, ranging in concentration from 0.8 pCI/l to 1.2 pC1/l. As indicated throughout this report, Sr-90 concentrations can be attributed to atmospheric testing. Overall Sr-90 levels have decreased slightly from 1977 but the 1980 indicator station was up slightly from 1979 Strontium-89 was detected in one on- E si te sample and two of f-si te samples analyzed during 1980. The Sr- 5 89 concentrations ranged from 0.7 pCi/l to 1.4 pCl/1. The highest concentration of Sr-89 was detected at the off-site location. The g presence of Sr-89 in the lake water samples is not considered to be g significant and is not attributed to the operation of the plant. Gamma spectral analyses were performed on thirty-six (36) monthly composite samples required by Technical Specifications. Gamma analysis was also performed on twenty-four(24) discharge canal monthly composites required by plant procedures. Technical specifl-cation samples were collected from the inlet canals of both the Nine Mile Point Uni t I facili ty and the James A. Fi tzPatrick facili ty. The control station samples were collected at the City of Oswego water intake prior to treatment. No radioisotopes were detected in any of the lake water samples analyzed for the 1980 sample program. Lake water gross beta activi ty from 1974 to 1980 and monthly gross beta results have been graphed and are presented in Section Vll. I I I I l I I I 83 I
I I B. LAND PROGRAM The results of terrestrial sample analysis for the 1980 reporting I period are presented in Table 9 through 23

1. Air Particulate Gross Beta - Tables 9 and 10 Tables 9 and 10 contain the air particulate gross be.ta results for the six (6) of f-site and nine (9) on-si te sample location respectively.

The samples were collected on a weekly basis and were counted after twenty-four hours to allow for the decay of short half-life radio-isotopes. No significant levels of gross beta activity was present on the 311 off-site samples or 466 on-site samples analyzed during the 1980 program. The off-site samples showed a gross beta activity slightly greater than the associated on-site samples collecjed during theofsame 0.044sample pCi/m pg)riodThe (of f-site mean of 0.056 pCI/m , on-I site mean . presence of slightly higher beta activity in the off-site samples over the on-site samples was also gbserved for the 1979 sample rgsults (off-site mean of 0.073 gross pCi/m , co-si te mean of 0.056 pct /m ). Both the off-site and on-si te gross beta activity were down by half from the 1977 and 1978 and as much as six times lower than the 1969 activity levels. The 1980 data showed a slight decrease from 1979 activity levels which I may indicate a continuing downward trend but this decrease is slight and could also be attributed to random statistical fluctuation. A review of the 1980 data on a weekly basis shows a number of spikes during the year. The general trend for gross beta concentrations I show that the on-site stations generally foiiow the changes in activi ty of the of f-si te stations but to a lesser degree. Weeks 34 and 40 show defini te increases in off-site particulate gross beta concentrations with the on-site stations showing a similar increase of activi ty but on the order of one-half the of f-si te concentration. The spikes in gross beta activity can be contributed to changes in the concentration of the naturally occurring isotopes found in the biosphere. The concentrations of naturally occurring isotopes in the lower levels of the atmosphere directly above the terrestrial portions of the earth are af fected by time-related processes such I as wind di rection, snow cover and moisture content of the soil. The fluctuation of natural background concentration and the f 3ct that the People's Republic of China conducted a nuclear atmospheric detonation during 1980 can be considered the major reasons for I measured increases and decreases in gross beta activity both on-si te and of f-si te. A graph of air particulate gross beta activity can be found in Section Vll. I I g -

2. Monthly Particulate Composites - Table 13 The air particulate filters collected each week are composited monthly by location (off-site /on-site) and analyzed for gamma E emitters. 3 During the 1980 sample period positive activities were detected for Cs-137, Mn-54, Co-58, Co-60, Nb-95, Zr-95, Ru-103, Be-7, Ce-141 and Ce-144. These isotopes were measured at both the off-site and on-site sample locations. The radioisotopes measured in the monthly ai r particulate composites can be divided into three categories.

The first category is naturally occurring isotopes. Be-7 was the caly naturally occurring isotope detected in the 1980 samples and was measured in all twenty-four composi tes analyzed (twelve of f-site, tweleve on-site). The second category would be radionuclides - which are possibly plant related. Included here would be Cs-137, Co-60, Co-58 and Mn-54. Cs-137 was included in this group for the purpose of conservatism. The presence of Cs-137 in particulate samples is most probably the result of past weapons testing with a small contribution f rom plant ef fluent. It should be noted that the maximum Cs-137 concentration was detected in both the on-site g and off-site composites. Cs-137 was measured in six of the twenty- g four monthly composi tes, twice in the of f-si te samples and four times in the on-site samples. concentrations were 0.001 pCi/m}he two of (May) and 0.0005 f-si te sample gs-137(July). pCi/m The four on-si te sampigs ranged in concentration f rom 0.001 pCi/m (July) to 0.0004 pCl/m (February). The concentration of Cs-137 in milk samples resulting from an air concentration of Cs-137 can be E calculated. Assuming that a cow was grazing at a location in the 3 environmentwheretheCs-137aircongentrationwasequal to the maximum concentration of 0.001 pCi/m , an estimate of the resulting concentration of Cs-137 in the milk can be made. Using methods found in USNRC Regulatory Guide 1.109 (Revision 1 ,asabasjsfor the calculation, and a X/Q-D/Q ratio of 140 pCi/m per pCl/m , the resulting milk concentration would be less than 1.0 pCi/1. The results of the calculation are conservative because the fraction of the deposited Cs-137 activity retained on the pasture grass was assumed to be 100 percent (r=1.0). In addition, decay time was considered negligable and soil uptake was assumed to be zero due to the 100 percent surface retention factor for the Cs-137 The three remaining radioisotopes in the second category are two isotopes of cobalt and manganese-54. None of the three isotopes were detected E in the of f-si te sample composites. Co-60 was detected in four of 3 the on-site sample composites. Mn-54 and Co-58 were detected in-the on-site composites only once each. The third category of radionuclides detecteo is the direct result of the atmospheric nuclear test conducted by the People's Republic of China on October 16, 1980. The resul ting f allout from this test was measurable at both the off-site and on-site stations. The fallout radionuclides were Nb-95, Zr-95, Ru-103, Ce-141 and Ce-144. These isotopes are characteristic of fallout from the detonation of atmospheric nuclear devices. Each of these radionuclides was detected in both the off-site and on-site composite samples in November and December 1980 wi th the exception of Ce-144 which was
I I not measured in the November on-site samples. Prior to the November samples, none of the fallout category nuclides were detected in any I of the composite samples. It should be noted that concentrations of each of these fallout radionuclides were greater in the December sample than the levels measured in the November sacole. Dose to man calculations can be made using inhalation rates and air le resul ts; Using the average concentrationsbasedonairsamg/yearandmaximumconcentration adult inhalation rate of 8000 m measured at the on-site sample stations, the following yearly doses can be calculated: Isotopes (10 ~3 pCi/m3 ) Origin Dose (mrem / year)* I Cs-137 (1.0) Plant / Fallout 0.00008 Co-58 (0.5) Plant 0.00046 I co-60 Mn-54 Nb-95 (1.0) (0. 3) (9.8) Plant Plant Fallout 0.00569 0.00024 0.00049 Zr-95 (10.0) Fallout I Ru-103 Ce-141 (4.9) (3.9) Fallout Fallout 0.01768 0.00025 0.00014 Ce-144 (2.0) Fa1Iout 0.01510 TOTAL 0.04020

Dose to the lung it should be stressed that the above listed yearly doses are calculated using the assumption that the maximum concentration was present for I the entire year. In reality, each of the radionuclides used above for the dose calculations were detected only in a portion of the samples collected during the year. Cs-137 and Co-60 had the highest I percentage of detectable concentrations with positive identi-fication in four of the twelve monthly composite on-site samples.

In contrast, Mn-54 and Co-58 were only detected in one monthly sample. The above table illustrates that the maximum potential dose to man from plant-related isotopes is insignificant even when calculated for a yearly exposure period. 3 Airborne Radioiodine (1-131) - Tables 12 and 13 The results of I-131 (charcoal cartridge) sampling and analysis are presented in tables 12 (of f-si te) and Tat te 13 (on-si te) . I During the 1980 sampling program, 1-131 was not detected in any of the three-hundred-twelve (312) weekly samples collected f rom the I six off-site sampling stations. 1-131 was detected in one er the four-hundred-sixty-six (466) weekly samples collected f rom the nine on-site sampling stations. The one measurable concentration of l-131 was in week No. 6 (sample of February 11, 1980) callection from I I g -
I on-sitesamplestatjon1. The concentration of this sample was 0.013 + 0.003 pCi/m . The LLD values for the 1-131 analysis ranged 3 from0.0065to0.056gCi/m at the off-site stations and from 0.0067 to 0.077 pCi/m at the on-site stations. The results of the g 1980 1-131 sampling effort Indicate no significant environmental 3 impact.

4. TLD (Envi ronmental Dosimetry) - Table 14 TLD's are collected Once per quarter during the sample year. The TLD results are an avarage of four independent readings and reported g in mrem / standard monto. Each location has two TLD's with each TLD 3 containing to distinc1 calcium sulfate dosimeter chips, in 1980 a special collection was made in May which resulted in five collections a with the April to May collection and the May to July collection I representing the second quarter.

TLD results are organized into three groups for reporting purposes. l The groups are on-site (defined as TLD's within the site boundary, 5 si te boundary TLD's (TLD's located at the site boundary) and off-site (TLD's located off-site ranging up to twenty miles f rom the g site). The net dose at the site boundary can be calculated by g subtracting the of f-site dose from the site boundary dose based on quarterly (total mrem) readings: Quarter Site Boundary Dose (mrem) 1 0.09 E 2 0.00 g 3 0.18 4 0.00 TOTAL 0.27 The annual site boundary dose for 1980 is estimated to be less than E l 0.3 mrem. The calculated annual site boundary dose is well within 3 l possible variation in natural background. TLD numbers 31, 32, 39 and 40 are located within the Nine Mile Point Unit 1 (NMP-1) restricted area near the radwaste facility and l are influenced by the close proximitv co the building. TLD numbers l 27 through 30 are located within ine James A. FitzPatrick restricted E l area near the radwaste facility and are influenced by the radiation 5 levels f rom the bul M!ng. TLD numbers 43 through 49 were added to the program in May of 1980. Their addition is in response to the g NRC Regulatory Guide on TLD placement. TLD number 39 was located I in the imediate vicinity of NMP-1 radwaste building f rom January I until May 17, 1980. Due to construction on the new NMP-1 radwaste ( facility, this TLD was moved a short distance away thereby signifi- E l cantly reducing the dose to the TLD. 5 ! B7 l I
The results for 1980 show that no impact f rom di rect radiation was measured outside the site boundary. A graph of TLD results is presented in Section Vll. 5 Radiation Monitors - Table 16 I Environmental radiation monitors are located in ten of the fif teen ai r moni toring envi ronmental stations. Each of the on-site environ-mental monitoring stations contain a radiation monitor and in addi tion, the C of f-si te moni toring station contains a similar I monitor. The radiation monitors consist of a GM detector with an associated power supply, chart recorder and trip uni t. The monitor has an operating and recording range from 0.01 to 100 mrem / hour. Each radiction monitor has a small radioactive source mounted inside the detector casing to produce an on-scale reading. The design intent of the monitors is to detect possible dose rates resulting from plume releases from the plant. The monitors are not I considered to be capable of high sensi tivi ty envi ronmental moni tor-ing and do not detect minute fluctuation in levels of background radiation. Because of the relatively poor sensitivity of the I moni tors (environmentally speaking) no comparisons are made between the radiation monitor readings and the readings from environmental TLD's.

6. Milk - Tables 16, 17, 17A and 18.

Milk samples are collected from each of six (6) farms in the first I half of the month and analyzed for 1-131. At approximately mid-month, a second milk collection is made at the same six farms. The second collection is composited with an equal aliquot from each i f arm sampled during the fi rst collection. The compos te samples I are analyzed for gamma emitters and Sr-90. 1-131 resuits are found on Table 16, gamma isotopic results are on Table 17 and Sr-90 results are on Table 18. Milk samples were collected from January through December which was i a continuation of milk sampling from the 1979 program. Sample l location number eight (8) was dropped from the sampling program in 1 January of 1980 at the request of farmers. The retired milk sample station was replaced by station number twelve (12) in May of 1980. Miik samples were collected monthly f rom January through September. IE in October 1980 sample frequency was increased as the result of the l 3 detonation of an atmospheric nuclear device. Prior to the November 11, 1980 milk samples, no measurable levels of I-131 were detected in milk samples collected for the 1980 program. , I 1 lI I 88 l
I Special milk collections were initiated on October 27, 1980 in response to the notification that the Peoples Republic of China had detonated an atmospheric nuclear device on October 16, 1980. The series of special milk collections initia11:ed on October 27, 1980 g were continued through December 15, 1980 with a total of five (5) E i collections during this period. The results of these collect ons are as follows: MILK SAMPLES - l-131 pCi/l Location Samole Dates 1980 10/27/80 11/03/80 11/26/80 12/01/80 12/12/B0 12/15/80 4 <0.2 0.4+0.2 <0.3 <0.3 <0.2 <0.2 13 <0.2 1.L0+0.3

As noted above, positive concentrations of I-131 were detected in I I the November 3, 1980, November 26, 1980 and the December 1, 1980 samples. In the November 3, 1980 samples, 1-131 was detected in three of the six locations with the control station (13) naving the highest concentration with a measurable level of 1.4 pCi/1. In the following weeks (November 26, 1980, December 1, 1980), I-131 was detected at only one farm, location 25 The source of the measured 1-131 was determined to be the atmospheric nuclear device detonated on October !6, 1980 by People's Repuclic of China. The resulting fallout from this detonation was expected to pass over the Eastern United States on October 21, 1980. I l I I i 39 l
I The tact that 1-131 was detected in the control sample on November 3, 1980 strongly suggests that the expected fallout was the source I of the radioactive material detected in recent milk samples. The fact that positive levels of I-131 were detected in the milk samples collected on November 26, 1980 and December 1, 1980 at sample location 25 (on-site) and not at the other milk sample locations I can be contributed to a difference in farming practices. Based on communications with the owners of the farms sampled, it was determined that the dairy herds were taken off pasture on approximately I November 1, 1980. The exception was sample location 25 According to the owner, his cow (mlik herd is comprised of one (l ww) was i left to feed on pasture as long as possible for econom c reasons, which was until shortly after December 1, 1980. At the other I locations, cows were fed stored feed Indoors and were allowed to exercise 3-4 hours per day outside. At these locations there were very small amounts of accessible pasture grass available, therefore, I pasture feeding was very limited during the exercise period. An investigation was undertaken to further evaluate the suspected source of the 1-131 in the milk samples. Plant operating parameters, environmental factors, related data and ef fluent release rates'were scrutinized. The results of this investigation further Indicated that the 1-131 in the milk samples was the direct result of fall-I out from the nuclear weapons test. November 3, 1980 milk analysis results showed that positive 1-131 levels were detected at locations southeast and southwest of the site while a review of meteorlogical I data between October 26, 1980 and November 3, 1980 showed that during this time period winds were from a southerly and northwesterly direction indicating that possible release from the plant should not ,,cve affected these sample locations. Analysis of air radiolodine samples around the site, both on-site and off-site showed no detectable 1-131. Further, a review of Nine Mile Point Unit I and the James A. FitzPatrick Plant stack and vent effluent data showed no effluent release rates that should account for the detectable levels found in the milk samples at any of the milk sample locations. A review of meteorological data with respect to the November 26, 1980 and December 1, 1980 samples for location 25 showed that wind I roses with a potential for depositing material from the site effluents existed less that 20% of the time (November 17, 1980 - December 1, 1980). I I I 90 I I
I Two additicaal factors are important in determining the source of the 1-131 in the milk samples. Positive levels of I-131 in milk were detected by three other nuclear power plants located in the northeast. These plants were the Salem Nuclear Power Plant, Peach Bottom Nuclear Power Plant and the Susquehanna Nuclear Power plant. It should be noted that the Susquehanna plant is not yet in commercial operation. The fact 1-131 was detected by other utilities in the northeast indicates that there was a wide area of fallout deposition as a direct result of the nuclear weapons test. The final item which Indicates the presence of nuclear test fallout is the result of high sensitivity gamma spectral analysis of air particulate samples collected around the site during the milk, sample collection period (on-site, October 27 to December 1, off-site, October 28 to December 2). The results of these analyses showed positive identifi-cation of the following radionuclides at both the on-site and off-site air monitoring loctions (composite samples): Isotope Half-Life Cerium - 144 284 days ' Carium - 141 32 days E lodine - 131 8 days 3 Ruthenium - 103* 39 days Barium - 140 13 days Zirconium - 95 64 days Niobium - 95 4 days Lanthanum - 140 40 hours

detected only in the off-site composite The array of radionuclides identified in the air particulate composites could be considered a " fingerprint" of nuclear atmospheric test fallout, as all these nucildes are fission products with relatively short half-lives and are not routinely identified in plant effluents.

The presence of the source of the lodine-131 in recent JAF/NMP milk sample is a direct result of atmospheric fallout from a nuclear i device de:onated on October 16, 1980 by the People's Republic or' l China. The resulting dose to a child from consumption of milk containing I 8.8 pCi/1, 1-131 would be 0.0013 mrem / year to the whole body and 0.76 mrem / year to the ht yroid. This dose calculation is based on l the assumption that the individual consumed 15 liters of milk in a 5 30-day period, during which the I-131 concentration remained constant at 8.8 pCi/1. 1-131 concentrations data for 1980 and previous years have been graphed and are found in Section Vll. The gamma spectral analyses of the monthly composite samples showed l potassium-40 to be the most abundant radioisotope detected in the l l milk samples collected in 1980. K-40 was detected in every sample a analyzed and ranged in concentration from 1100 pCi/l to 1800 pCi/1. K-40 is a naturally occurring isotope and is found in many of the environmental media sampled. 91 I
f i Cesium-137 (Cs-137) was the second most abundant radionuclide ; detected in the 1980 milk samples. Cs-137 was measured in twenty-one (21) of forty-seven (47) montb!y composi te sample analyzed. Special milk samples were collected from January through April in 1980. The special samples were collected once a month and were initiated to determine the Cs-137 concentration in milk while milk I animals were off pasture and were fed only stored feed. Cs-137 was measured in seven (7) of the twenty (20) special (off pasture) samples collected and analyzed. Cs-137 was detected in milk samples I at all locations sporadically during the year. Concentrations remained small throughout the sample season and were considerably less than noted in previous years (1974,1975). The 1980 samples showed detectable concentrations ranging 3.5 pCi/l to 21.0 pCi/1. Sample location 25 had the highest yearly mean of 14.4 pCi/l (average of 1/80 - 4/80 monthly samples and 5/80 - 12/80 monthly composite samples) with a maximum of 21.0 pCi/l measured in both the January I and August samples. The detection of Cs-137 in the milk during the winter months is due to concentrations of Cs-137 in the winter feed (fodder crops). The presence of Cs-137 was detected in grain, hay and corn silage samples collected during 1980. This data is presented in Table 23 Cs-137 was detected in grain at four (4) of the five (5) indicator sample stations but was not measurable at the control station. Because grain is not grown I locally and is processed from areas of considerable distance from the plant, the presence of Cs-137 in the grain indicates that the source of the cesium is most probably from weapons testing fallout. I Cs-137 was also detected in locally grown fodder crops including the control station, again indicating that the probable source of the radionuclide was weapons fallout. A sample set of pasture grass was collected during the month of September, again Cs-137 was I detected at the control station as well as four (4) of the five (5) indicator stations. The variation in concentrations of Cs-137 in various fodder crops may be due to difference in soil types as cesium is less available for plant up-take in clay rich soils than in soils that are high in organic matter. The results of soil j analysis for Cs-137 collected at each of the milk sample locations shows measurable levels at each of the locations and having a l relatively small range of concentrations (0.61 pCi/g (dry) *.o 1.2 I pCi/g (dry)) with a mean f 0.9 and a standard deviation of 0.2 l pCi/g (dry) for the range. It should be noted that the milk sample

control station had the high soil content of Cs-137 for the September collections.

l g The significance of Cs-137 in the milk samples can be determined by 3 calculating the dose to man as a result of milk consumption. Assuming the maximum milk consumption rate of 400 liters / year for a teenager and the Cs-137 concentration for the year equal to 21 pCi/1, the dose to the teenager would be 1.25 mrem / year to the liver and 0.44 mrem / year to the whole body, it should be noted that Cs-137 levels in the 1980 sample are down from those measured in 1974 through 1976.
I Strontium-90 (Sr-90) in milk was measured in each of the samples collected from the six (6) milk sample locations. The mean yearly concentration for the control station is consistent with the past Sr-90 results. The mean yearly concentration for the indicator E locations is slightly less than previous years which may indicate a E reduction in the atmospheric / terrestrial inventory (the Chinese Weapons test in October may increase this inventory however). Sr- g 90 levels in milk are well documented (NCRP 45 and 52) and reached g a 1963 high of of 28 pCi/1. Sr-90 concentrations of 7-10 pCi/l were noted during the 1970's. The levels of Cs-137, 1-131 and Sr-90 in milk samples are presented in graphic form in Section Vll. 7 Milch Animal Census - Table 19 The milch animal census is an estimation of the number of cows or goats wi thin the ten mile radius of the Nine Mile Point Site. A census is conducted twice per year, once in the spring and once in the summer. The census is conducted by sending questionnaires to previous milch animal owners and also by road surveys to locate'any possible new owners. No responses to questionnaires are followed-up by telephone calls. The number of milch animals located within the ten mile radius of the Site was estimated to be eight-hundred-ninty-nine (899) cows and three (3) goats for the 1980 spring census, which is a decrease of four (4) cows and an increase of three (3) goats from the Spring, 1979 census. The 1980 summer census showed a total of eight-hundred-ninty-five (895) cows and five (5) goats. This represents an increase of fifty-seven (57) cows and an increase of five (5) goats from the fall, 1979 census. I I I l I l 93

8. Human Food Products - Table 20 I The results of analysis performed on meat, eggs, poultry and produce are presented in Table 20.

l Meat, eggs and poultry were collected during the spring and fall with'n a ten mile radius of the Nine Mile Point Site. In addition, control locations were added to the fall survey which were outside the ten mile radius. The ultimate factor controlling sample locations was the availability of the required samples. Three indicator locations were sampled for each type of media. Meat samples collected during the spring showed detectable concentrations of potassium-40 (K-40) in all three samples. K-40 is a naturally occurring radioisotope. Two of the three samples showed conc antrations of Cs-137 which were slightly higher than detectable limits. Cs-i 137 in food products has been noted in the literature and ranged l well over 100 pCi/g daring the early 1960's. The Cs-137 measured l in the meat is most probably the result of atmospheric fallout from l weapons testing and has been detected in similar concentrations in l previous years. Samples collected in the fall of the year also l showed concentrations of K-40 and Cs-137 Cs-137 was detected in l three of the four samples. The three samples showing concentrations l of Cs-137 were the control sample and two indicator samples. The l two indicator samples were not statistically significant from the l control sample based on the analytical error associated with such l small concentrations. I 1 i Egg samples collected during the spring and fall showed measurable I concentrations of K-40 at all locations. No other radionuclides were detected in the egg samples analyzed for gamma emitters. l Poultry samples taken during the spring collection showed concentrations i l of K-40 only. Fall samples also showed concentrations of K-40.

E One of the three indicator samples (fall collection) contained a small measurable amount of Cs-137.

Fruits and vegetables were collected during the harvest season. j Three indicator locations and one control location was sampled I based on selection criteria stated above for meat, poultry and egg 'l samples. At each location an attempt was made to sample a broad W leaf vegetable for I-131 analysis. The first series of collections was made in August which contained lettuce, tomatoes, spinach and l cabbage which were selected due to their availability. All eight l samples contained measurable levels of K-40 at approximately the same concentration. Three of the six indicator samples contained a measurable amount of Cs-137 which was slightly above the LLD for the control station samples. Also detected in the August collection was Be-7 and Ra-226 both naturally occurring radioisotopes.

~

Broad leaf vegetables were collected and analyzed for 1-131 in the October collection. No 1-131 was detected in any of these samples, which were counted within eight (8) days. Cs-137 was detected in one indicator and one control sample with the higher concentration measured in the control sample. As in August, K-40 was detected in each of the samples. The dose to man from Cs-137 concentrations in broad leaf vegetables can be calculated. Using the maximum annual consumption of green leafy vegetables of 42 Kg/ year for a teenager and the maximum Cs-137 concentration of 0.05 pCi/g, the resulting dose would be equal to 0.11 mrem / year to the whole body and 0.31 mrem / year to the liver. As in the other sample media analyzed, the resulting dose to man from nuclides detected is very small in s. comparison to natural background. I l I I l I l l 1 I 95
1 I l 4 C. CONCLUSICH The Radiological Environmental Monitoring Program is conducted each j year to determine the radiological impact of the James A. Fitz-Patrick Nuclear Power Plant on the local environment. As demonstrated i by the analytical results of the 1980 program, the major radiological impact on the environment was the result of fallout from atmospheric nuclear testing. g The levels of natural background and the associated fluxuation in g intensity are much more significant in terms of dose to man (normal '

background in the vicinity of the site is equal to 60 mrem / year) l l than radiation levels in the environment associated with the

! operation of the plant. , , i Using the data presented in this report, and earlier reports as a ) basis, it can be concluded that no appreciable radiological environmental impact has resulted from the operation of the James A. FitzPatrick Nuclear Power Plant. l l i l I l l l l { I I I I l l l l I II l
