O I-A INTRODUCTION The New York Power Authority (NYPA) is the owner and licensee of the James A. MtzPatrick Nuclear Power Plant (JAFNPP) which is located on the eastern portion of the Nine EHle Point promontory approximately one-half mile due east of the Niagara Mohawk Power Corporation (NMPC) Nine &Hle Point Nuclear Power Station (NMPNPS). The NMPNPS Unit #1 is located on the western portion of the site and is a boiling water reactor with a design capacity of 620 MWe. The NMPNPS has been in commercial operation since j the fall of 1969. I,ocated between the JAFNPP and NMPNPS, Nine Mile Point i Unit #2 is under construction. NMPNPS Unit #2 will have generation capac-

- ity of 1,100 MWe and is expected to be completed in 1986. The JAFNPP is

, a boiling water reactor with a power output of 810 MWe (net). Initial fuel .

j loading of the reactor core was completed in November of 1974. Initial criticality was achieved in late November, 1974 and commercial operation ,

began in July of 1975.

The site is located on the southern shore of I,ake Ontario in Oswego County, New York, approximately seven miles northeast of the city of

, Oswego, New York. Syracuse, New York is the largest metropolitan center in the area and is located 40 miles to the south of the site. The area con-

' sists of partially wooded land and shoreline. The land adiacent to the site is used mainly for recreational and residential purposes. For many miles to j the west. east and south the country is characterized by rolling terrain

, rising gc.tly up froct the lake, composed mainly of glacial deposits. Ap-proximately 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 respcnsibility for the program shared by the Power Authority and Niagara Mohawk. SimMar Technical Specifications for

radiological =cnitoring of the environment allows for majority of the sam-pling and analysis to be a joint undertaking. Datr generated by the pro-gram is shared by the two facilities with 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 DPR-59, Docket 50-333. Environmental reports of this nature have been compiled and submitted in semiannual and annual reports since 1974.

This report contains data from samples representing the period from Janu-ary 1,1984 to December 31, 1984.

1. SA.9LE COL'ECTION METHODOLOGY A. Lake Water (surface water)

. l The two indicator stations are the respective inlet canals at JAFNP? and NMPNPS. These samples are composited using continuously running pumps which discharge into large holding l tanks. j The control station sample is collected from the city of Oswego water intake. The sample is drawn from the intake prior to treat-ment and is composited in a large sample bottle.

Quarterly composite samples are made up from proportional ali-quotes of monthly samples.

B. Air Particulate / Iodine The air sampling stations are located in two rings surrounding the site. The onsite locations ring the terrestrial area around the plants inside the site boundary.

The onsite sampling network is composed of nine stations. The offsite air e.cnitoring locations range six to 17 miles from the site and are composed of six stations. Air monitoring Iccations are ,

shown on Figures 1 and 2 of Section VII. '

The air particulate glass Sber Siters 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 Siter is a2 x 1 inch charcoal cartridge used to absorb airborne ,

radiciodine. The samplers run continuously and the charcoal 4 cartridges and particulate futers are changed on a weekly basis. II The particulate Siters are composited on a monthly basis by loca- ,

tion (offsite, onsite) after being counted individually for gross I beta activity.

~

1 C. Milk <

During the Srst two months of the 1984 grazing season, milk was I collected from eight locations. During the remainder of the 1984 grazing season, milk samples were collected from seven locations. ,1 Six of these locations are considered indicator samples and the }

seventh is used as a control sample. Milk samples are collected in I polyethylene bottles from the bulk storage tank at each sampled ',

farm. Before the sample is drawn the tank contents are agitated from three to Sve minutes to assure a homogenous mixture of milk j

and butterfat. Two gallons are collected during the Srst week of '

each month from each of the farms. An additional one gsllon is l

d from each farm at mid month to make up the second half monthly composite. The complate composite is made up from Don conected during the first week of the month and one

. from the mid month collection. The samples are frozen and l to the analytical contractor routinely within 36 hours4.166667e-4 days 0.01 hours 5.952381e-5 weeks 1.3698e-5 months of '

I m in insulated shipping containers. The milk sampling lo-are found on Figure 4 of Section VII.

D. *oultrv and Eggs 1

i ius11y one kilogram of meat is conected from locations within le radius of the site. Periodic phone calls are made to the aughter houses to determine availability of slaughtered live-rom within the sampling area. Whenever possible meat sam-Je conected from locations previously used. Attempts are 4 conect a control sample located outside the 10 mile radius, i th series of conections.

!ually one kilogram of poultry and one kilogram of eggs are 4 from each of three locations within a 10 mae radius of the f attempts are made to conect poultry and eggs at the same I

t the meat samples. The poultry and eggs are frozen and

s in insulated containers. Whenever possible samples are a from previously sampled farms. Attempts are made to et control sample located outside the 10 mile radius, with eies of conections (see Section VII, Mgure 5).

4 E. Wood Croos Rfood crops are conected during the late summer harvest l set locations previously sampled, if available. One kilogram et the two types of fruits and/or vegetables from each of the locations within a 10 mile radius of the site are conected.

Ties of fruits and vegetables sampled depend on what is lo-1

' endlable at the time of collection. Attempts are made to col-levast one broad leaf type veg1 table from each location. The frid vegetables are chined prior to shipping and shipped fainsulated containers. Attempts are made to conect a con-tr9le located outside the 10 mile radius for each type of sam-pl8Section VII, Figure 5).

' l**

Sables are required once every three years. Samples were i

col during 1983. Soil samples were taken at each of the 15 1

airoring stations at that time. No son samples were conected dugg4, l

G. g Avs fish species are removed from the Nine Mile Point Aquatic EcoStudy monitoring collections during the spring and fall I 5

i i

l conection periods. Samples are collected from a combination of the i four onsite sample transects and one offsite sample transect (see Secdon VII, Figure 1). Available species are selected under the ,

h11owing guidelines:

1) 0.5 to 1 kilogram of edible portion only of a maximum of three species per location.

2) Samples composed of more than 1 kilogram of single species from the same location are divided into samples of 1 kilogram

each prior to shipping. A maximum of three samples per spe- l cies per location are used. Weight of samples are the edible i portions only.

Selected fish samples are frozen immediately after :ollection and ,

segregated by species and location. Samples are shipped frozen in insulated containers for analysis.

1 H. GASI&fARUS GAhBTARUS (fresh water shrimp) samples are conected by EA per- l' I sonnel dunng the spring and fall season from two onsite locations and from one offsita location. Natural and artificial substrates are used to collect samples. The GASf3fARUS samples are removed ,

tractor in insulated shipping containers. 8 I. Stonusks f

During the spring and fan seasons at two oncite locations and one offsite location benthic samples are collected. The mollusks are l collected by divers and sorted. The tissue is removed from the i shell, frozen and shipped for analysis in insulated containers.

1 J. Bottom Sediments 4 One kilogram of bottom sediment sample is collected at two onsite locations and one offsite location. Samples are conected at the same time and location as the mollusk samples, where possible, by a diver. The samples are placed in plastic bags, sealed and shipped for analysis in insulated containers. ,

K. Periphyton -

Periphyton (fresh water algae) samples are collected in the spring and fan seasons from two onsite locations and one offsite location.

Periphyton is conected from natural substrates. The periphyten is scraped from the substrates into vials, labeled, frozen and shipped l in insulated centainers for offsite analysis.

L. TLD (direct radiatien)

Thermoluminescent dosimeters (TLD's) are used to measure direct radiation in the JAF/NMP-1 environment. The TLD stations are placed around the site using a two zone distribution. The first group of TLD's is located within the site boundary and are called "onsite" TLD's. The second set of TLD stations is the "offsite" stations, located at the offsite air monitoring stations and in areas of special interest such as population centers. Also included in .

the offsite group are the field control TLD's. A total of 45 TLD stations were used for the 1984 TLD program.

TLD's used during 1984 were rectangular TeDon wafers impreg-nated with 25 percent CaSOS :Dy phosphor. These were sealed in a polyethylene package to insure dosimeter integrity. The TLD packages are further protected by placement in plastic holders, or by tape sealing to supporting surfaces. The dosimeters are collected, replaced and evaluated on a quarterly basis.

l j ; 3. CHANGES TO THE 1984 sat!PLE PROGRAM A. &H1k sample locations number 5 and number 45 were deleted from l the milk sampling program in July of 1984. Several other milk l

sampling locations had been located, as a result of milch animal censuses conducted during 1983-84, that demonstrated greater radionuclide deposition potentials. Since locations 5 and 45 had lower potentials for deposition, as determined by D/Q values, these locations were deleted.

B. 5HIk sample location number 60 was added to the milk sampling program in July of 1984. This location was added as a result of the milch animal censuses conducted during 1983-84. This location demonstrated average potentials for radionuclide deposition, as determined by D/Q values.

C. Environmental radiation monitor C offsite was moved to environ-mental sampling station D-1 offsite on July 19, 1984 (1205 hours0.0139 days 0.335 hours 0.00199 weeks 4.585025e-4 months ).

This move was a result of repeated vkndalism to environmental ,

sampling station C offsite (the monitor detector was repeatedly

stolen) .

2. ANALYSIS PERFORMED The analysis of the environmental samples is performed by Teledyne Isotopes (TI) and the James A. FitzPatrick Environmental Counting n Laboratory (JAFECL) . The following samples are analyzed at the JAFECL:

Air Particulate Filter - gross beta (weekly)

Air Particulate Filter Composites - gamma spectral analysis (monthly) -

Airborne Radiolodine - gamma spectral analysis (weekly)

Surface Water Composites - gamma spectral analysis (monthly)

Special Samples (soil, etc.) -

gamma spectral analysis (as collected) '

The remainder of the sample analysis as outlined in Tables I and II in this section is performed by TI.

A. Sample medium. l i

l B. Type of analysis performed. ,

1 C. Number of analyses performed.

D. Range of detectable levels. The data column is labeled " Lower Limits of Detection". This wording indicates that inclusive data i i is based on 4.66 sigma of background. l l 1 i

E. 5fean value of the data, based on positive measured values *,

i I F. Standard deviation, based on positive measured values. (The standard deviations represent the variability of measured results for different samples rather than single sample uncertainty *.)

l G. 51aximum and minimum values.

I V DATA SUMMARfES AND CONCLUSIONS I The results of the 1984 Radiological Environmental Monitoring Pro-gram are evaluated considering the natural processes of the environment and the aggngate of past data. A number of factors are consideredThe in I the course of this radiological data evaluation and interpretation.
I interpretation of data can be made at several levels including trend analy-sis, population dose, risk estimates to the general population based on environmental concentrations, effectiveness of plant effluent controls and
! specific rssearch areas, among others. An attempt has been made in this report not only to report the data collected during the 1984 sample pro-gram but also to assess the significance of the radionuclides detected in the environment. It is important to note that detection of an isotope is
!' not of itself an indication of its environmental significance. Evaluation of the impact of the radionuclide in terms of potential increased dose to man,
~~in relation to natural background, is necessary.~~
~~There are three separate gToups of radionuclides that were detected in the environment during 1984. A few of these radionuclides could pos-~~
sibly fall into two of the three groups. The first of these groups is i naturally occurring radionuclides. It must be realized that the environ-ment contains a broad inventory of naturally occurring radioactive ele-monts. Background radiation as a function of primordial radioactive elements and cosmic radiation of solar origin offers a constant exposure to the environment and man. These radionuclides, such as Th-232, Ra-226 Be-7 and especially K-40, account for a majority of the annual per capita l background dose.
i .
A second group of radionue11 des that were detected are a result of the detonation of thermonuclear devices in the earth's upper atmosphere, The detonation frequency during the early 1950's produced a significant j
inventory of radionuclides found in the lower atmosphere as well as in ecological systems. A ban was placed on weapons testing in 1963 which
' greatly reduced the inventory through the decay of short Ifved radio-i nuclides, deposition, and the removal (by natural processes) of radio-nuclides from the food chain such as by the process of sedimentation.
Since 1963, several atmospheric weapons tests have been conducted by the People's Republic of China. In each case, the usual radionuelfdes associated with nuclear detonations were detected several months after-wards and then after a peak detection period, dindnished to a point where most could not be detected. The last such weapons test was conducted in October of 1980. The resulting fallout or deposition from this test has influenced the background radiation in the vicinity of the site and was very evident in many of the sample medias analysed during 1981. Calcula-tions of the resulting doses to man from fallout related radionuclides in the environment show that the contribution from such nuolides in some cases (such as $r-90 or Cs-137) is significant and second in intensity only to natural background radiation, quantities of Nb-95, 2r-95, Co-141, Ce-144, Ru-106 Ru-103 La-140 Cs-13", Mn-54 and Co-60 were ty9ical in air particulate samples during 1981 and have a weapons test or gin.

The third group of radionuclides detected in the environment during 1984 were those that could be related to operations at the site. These select radionuclides were detected in a few of the sample medias collected and at very low concentrations. Many of these radionuclides are a by- ,
product of both nuclear detonations and the operation of light water i reactors thus making a distinction between the two sources difScult, if 3 '
l not impossible, under the circumstances. The dose to man as a result of 1 these radionuclides is small and signincantly less than the radiation exposure from naturally occurring sources of radiation and from fallout. ;
Thus, a number of factors must be considered in the course of i, radiolcgical data evaluation and interpretation. The evaluation and inter-protation is made at several levels including trend analysis, dose to man, etc. An attempt has been made not only to report the data collected during 1984, but also to assess the signiScance of the radionuclides detected in the environment as compared to natural radiation sources. It j i is important to note that detected concentrations of radionuclides that are possibly related to operations at the site are very small and are not an indication of environmental signineance. In regards to these very small I quantities, it will be further noted that at such minute concentrations the i 1 assessment of the signiacance of detected radionuclides is very difScult.
Therefore, concentrations in one sample that are two times the concentra-tion of another, for example, are not signiScant overall. Moreover, concentrations at such low levels may show a particular radionuclide in one sample and yet not in another.
In Section V each sample medium is discussed. Concentrations of radionuelldes detected and exposure to man are presented and scruti-nized.
I Section VI, titled HISTORICAL DATA, contains sample statistics from i previous envirormental sampling. The process of determining the impact (or lack of impact) of plant operation on the environment includes the l ,
scrutiny of past analytical data, a tool by which trendJ are discerned. :
The interpretation of historical data in this report is done to a limited degree. Because of the constant change in analytical sensitivities, as state-of-the-art detection capabilities improve, data comparisons become !
difScult. For example, minimum detection capabilities for the 1969 and I 1974 analyses of environmental samples would be considered anomalous by 1984 standards.

LAKE PROGRAM Tables 1 through 8 list the 1984 analytical results for the aquatic / lake i water media sampled during the 1984 sampling program. Aquatic samples were obtained at a combination of four onsite locations. The transact designations used for the onsite sampling locations 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 onsite transacts sampled for other media. Offsite samples were collected in the vicinity of the Oswego Harbor (offsite - 00).

1. PERIPHYTON SA31PLES - TABLE 1 Periphyton is a common fresh water algae found throughout the Great Lakes and in almost all underwater aquatic systems. Periphy-ton in its simplest form is a single celled organism which colonizes the natural and artificial substrates found in the shore and near shore waters. Colonies of periphyton can be found from the shore zone to water depths which can be suff!ciently penetrated by sunlight to support photosynthesis. Periphyton is dependent on sunlight and inorganic materials found in the lake to support life therefore putting it in the classification of a primary producer.
Periphyton in its simplest form is the slimy coating which is found on most underwater surfaces and has a brown to green coloration.
This organism is used as an indicator organism to help evaluate the possible effects of plant operation on the local aquatic envinnment on the lowest level of the food chain.
The ecuection and analysis of periphyton samples was performed !
twice during the 1984 sample program. .
The first conection of periphyton was completed on June 29, 1984 and the second conection was completed on September 12, 1984. The gamma spectral analysis of periphyton samples showed detectable concentrations of Cs-137. Be-7, Th-238 and K-40. The four radio-nuclides detected in periphyton samples can be attributed to several sources. Each of the radionuclides detected can be placed in one of ,
three groups. The first group, of radionuclides is the result of plant operation. The second group of radionuclides is naturally .
occurring and is found in many living organisms as noted throughout this report. The third group of radionucIldes is the result of past {
atmospheric nuclear weapons testing. Radlonuclides with relatively long half-lives which fan into this third group are the result of j atmospheric tests conducted over the past decades. The only fauout g related radionuclide detected in 1984 periphyton samples was Cs-137 Cs-137 requires special consideration as this radioisotope of cesium is {
a common constituent of the background radiation due to fauout but !
can also be attributed to the operation of the plant. In 1981 six -
fauout radionuclides were detected in the periphyton samples. Of the six radionucHdes detected in 1981, two, Ce-144 and Cs-137, were i detected in 1982, and one, Cs-137, was detected in the 1984 sam-ples. The other fauout radionuclides were not detected in 1982-84 because of their short half-lives (3.5 days to 368 days) which re-suited in their decaying away to concentrations below that of the lower Umits of detection (LLD) and as a result of ecological cycling.
The first set of periphyton samples conected on June 29,1984 con-tained detectable concentrations of Be-7, K-40, Cs-137, and Th-228. i The maximum detectable concentration for plant related radionuclides I was 0.29 pC1/g (wet) for Cs-137. Cs-137 was detected in both the control (offsite) sample and the two indicator (onsite) samples with the maximum concentration, as noted above, present in the ind!cator sample.
63
The second collection of periphyton samples completed on September 12 showed a slight increase in the concentration of plant related
- radionuclides. The maximum detectable concentration of plant related radionuclides in the second or summer collection was 0.31 pCi/g (wet) for Cs-137. Cs-137 was not detected in the second collection at the control location as it was in the first collection (June 1984).
The concentration of Cs-137 at the control location was less than i 0.064 pC1/g (wet) LLD.
Three naturally occurring radionuclides were detected in the 1984 samples. K-40 was detected in all six samples both onsite and off-site. B e-7 was detected in two onsite samples and one offsite sample. Th-22S was detected in two of the onsite samples. The concentration of the naturally occurring radionuclides was consistent with levels detected in previous years' samples. A general increase in the concentrations of radionuc!! des in the second or late summer collection compared to the June collection was noted for the 1984 samples at the indicator locations. A similar increase in concen-tration in samples collected in late summer was also noted in 1980, 1981,1932, and 1983. This increase in sample concentration may be due to the higher metabolic rate or increased growth of the periphy-ton community between the first and second collections. The Cs-137 detected in the 1984 samples were trace amounts and are attributed to both plant effluents and past weapons testing.
A dose to man calculation from the level of activity found in lake periphyton samples in the vicinity of the plant is difficult to make as periphyton is not directly in the human food chain. To best deter-mine the resulting dose to man from the activity found in periphyton samples, calculations were made based on concentrations found in fish samples as fish represent the upper level of the food chain in which periphyton is a primary producer. Dose to man calculations based on concentrations found in fish and consumption rates are contained in Section V.S.
A review of past data shows Cs-137 concentrations in both indicator and control periphyten samples decreased slightly since the 1983 samples. Graphs depicting concentrations of Cs-137, Co-60, and i
Co-144 are presented in Section VII.

~~2. BOTTO?! SEDDfENT - TABLE 2 Bottom sediment samples were ecliected twice during the 1984 sam-pling program. Gamma spectral analyses and Sr-90 analyses were '~~
performed on each of the six samples and the results are presented in Table 2. Samples were conected in June and October in 1984 with the Oswego Harbor area (transact (001) serving as the control loca-tion, Nine Stile Point Plant (transect (02]) and the Fit: Patrick Plant (transect (03]) serving u the indicator or onsite sample locations.
Sr-90 was detected in e'ach of the six 1984 samples. Cs-137 was detected in four of the six samples conected in 1984, which included three onsite samples and one offsite sample. Co-60 was detected in two of the six samples and afn-54 was detected in one of the six 1984 samples.
The presence of Cs-137 in the lake bottom sediment can be attri-buted to the accumulation of fallout in the aquatic environment as a result of the detonation of nuclear devices in the atmosphere. The origin of Cs-137 in atmosphere testing can be demonstrated by sam-ple results which show the presence of Cs-137 in control location sediment samples. The Cs-137 concentration for the control location was 0.42 pC1/g (dry). The Cs-137 concentrations for the indicator (dry) to 0.04 pC1/g (dry) with a locations ranged from
=ean concentration 1.08pC1/g of 0.49 pC1/g(dry).
Co-60 was detected in two of the four ind!cator samples conected in 1984. Positive detections of Co-60 ranged from a minimum of 0.12 pC1/g (dry) to a maximum of 0.17 pC1/g (dry). The detected levels of Co-60 are relatively the same as the concentrations detected in 1983 when the minimum concentration was 0.10 pCl/g (dry) and the maximum value was 0.16 pCl/g (dry). The detection of Co-60 in sediment can be attributed to the operation of the plant. Co-60 was not detected in the control samples conected in 1984. The levels of Co-60 detected in the ensite samples are very seau, and are near the lower umits of detection.
1!anganese-54 was detected in only one of the four indicator samples couected in 1984. The one positive detection was made at the F!tz-Patrick (03) transect. The 5tn-54 concentration for this one indicator location was 0.04 pC1/g (dry). The detection et Sin-54 in sediment can be attributed to the operation of the plant. !!n-54 was not detected in the centrol samples coUected in 1984. The average LLD value for the control location was less than 0.04 pC1/g (dry) LLD.
Thus, as can be seen from above, the Sin-54 concentration detected in the one onsite sample is very small, and at the lower limits of detection. '
Strontium-90 was detected in an of the six Bottom Sediment samples conected in 1984. The presence of Sr-90 at the control and indica-tor locations is considered to be the result of weapons fallout.
(
Sr-90 was also detected at both control and indicator sample locations 65 c .

i during 1978, 1979 1980, 1981. and 1983, which is evidence that Sr-90 is attributable to weapons testing fallout. The mean 1984 eentrol concentration for Sr-90 was 0.047 pC1/g (dry). The mean -
1984 indicator concentration for Sr-90 was 0.035 pCi/g (dry). ;
Variations in Sr-fr0 concentrations can be influenced by several !
l feetors including sediment type and chemical make-up. The presence r of Sr-90 in many of the other control samples supports the fact that i l Sr-90 is ubiquitous thmughout the environment. ,
[
l The dose to man from bottom sediment is not of concern and cannot i be directly calculated. Bottom sediment is not accessible to man and ,
the radioactivity found in the sediment is shielded by the overlaying !
water column. To Illustrate the impact of radioactivity in sediment !
l samples with respect to the dose to man concept, the assumption can be made that at some future time bottom sediment could be intro-duced into the shoreline sediment through re-suspension and depost-tion. Assuming that the density of the sediment is 40 kg/m8 (dry)
{4 and using the average residence time on the shore of 47 hours5.439815e-4 days 0.0131 hours 7.771164e-5 weeks 1.78835e-5 months per 1 year for a teenager, the annual dose rate from a maximum indicator ji sample Cs-137 concentration of 1.08 pCilg (dry) is calculated to be i i 0.0005 mrom per year whole body dose. The whole body dose from a i Co-40 concentration of 0.17 pC1/g (dry) would be equal to 0.0064 I mrom per year. The whole body dose fme a Mn-54 concentration of l I 0.04 pCilg (dry) would be equal to 0.0004 mese per year. The re- t l sulting total whole body dose would be equal to 0.0143 mrom per 1 year whole body. The contribution to the total whole body dose due l to Sr-90 would be inAnttesimal due to the fact that $r-90 decays by '
g a beta emission and has no associated strong gamma energy.
A review of past Cs-137 data illustrates that the mean concentration !
values for the indicator stations have dropped signiScantly from 1976 [
j )!
4 to 1979 with the general trend downward continuing from 1979 ,
j through 1982. The 1984 mean concentration of Cs-137 was slightly L higher than the 1983 value. Since 1979, the mean value for the con- [
trol station has been greater than the indicator stations with 1982 y showing a change in the downward trend for Cs-137 concentrations i at the control locations. However, the 1983-84 concentrations show a reverse in this situation. This change in tanding for the Cs-137
- concentrations may be the effect of the control location's close pron- !
indty to the Oswego River Outlet and a possible soures of Cs-137 :
from deposition of Cs-137 from atmospheric nuclear testing onto the ;
i river waterehed. The concentration of Co-40 in sediment samples j has shown a stadlar downward trend to that of Cs-137 since 1977. !
The nazimum Co-40 concentration in the indicator samples (mean) i l

~~3. MOLLUSK SAMPLES - TABLE 3 A total of six moUusk samples were collected in 1984 from a total of '~~
three general locations. Each sample was analyzed for gamma emit-ters using gamma spectral analysis and for Sr-90 using chemical sep-arations and beta particle analysis. The results of the 1984 samples are presented on Table 3. As in past years the effort to conect mollusk samples of sufficient size has been of limited success in terms of sample volume conected. The collections in 1984 were pro-ductive and resulted in sample volumes in the 500 gram range which in some cases resulted in good sensitivities for the gamma spectral analysis, in particular for the indicator samples. Mollusk samples were successfuny collected at the offsite (00) or control location and at the Nine Mile Point Plant (02) transect and the FitzPatrick (03) transect, for the indicator samples.
The results of the isotopic analysis of mollusk tissue detected the presence of six radionuclides. The nuc11 des detected consisted of two naturally occurring radionuclides (K-40 and Ra-226), three plant ,
related radionuclides (Mn-54, Co-60, and Cs-137), and one radionu-c11de related to fallout from atmospheric nuclear testing (Sr-90). ,
Detectable concentrations of Sr-90 were measured in each of six sam-ples collected at both the ensite and offsite locations. The presence +
of Sr-90 in all the mouusk samples collected for the sample year was also observed in 1979,1980,1981,1982, and 1983. The 1984 Sr-90 concentrations ranged from a maximum of 0.13 pct /g (wet) to a mini-mum of 0.009 pC1/g (wet) with the control station mean equal to 0.020 pC1/g (wet) and the indicator mean equal to 0.061 pCi/g (wet). As in other sample media the presence of Sr-90 is considered !
to be the result of fallout from atmospheric nuclear testing. This i determination is based on the fact that Sr-90 is consistently detected in control samples in previous years as noted above. Mn-54 was (
detected in each of the four onsite or indicator samples collected in ;
1984. Co-60 was detected in three of the four onsite samples, and Cs-137 was detected in only one of the onsite samples. The pres-ence of Mn-54 and Co-60 in mouusk tissue can be attributed to the !
operation of the plant. The Ca-137 present in the mouusk tissue i may also be attributed to the operation of the plant and/or fauout from atmospheric nuclear testing. The Mn-54, Co-60, and Cs-137 were not detected at the offsite or control locations. i The concentration of Mn-54 detected at the indicator locations ranged from a maximum of 0.11 pC1/g (wet) to a minimum of 0.06 pct /g '
(wet). Co-60 concentrations ranged from a maximum of 0.115 pCi/g ,
(wet) to a minimum of 0.040 pct /g (wet). The one positive detection for Cs-137 was 0.022 pC1/g (wet). ,
The relatively high frequency for the detection of Co-60 and partie- l ularly Mn-54 in mollusk samples can be attributed to the phenomenon of bicaccumulation or concentration factors. The level of an element ;
in a particular organism relative to the level or concentration of the j same element in the organism's environment is known as the concen-67 l

i i tretion factor. Fresh water mouusk have an extremely high ;
j concentration factor of 300,000 (mean) for Mn-54 and 32,408 (mean) ;
, for Co-80*. Such high concentration factors would result in a rapid l
> ' accumulation of manganese and cobalt activity in mouusk that are in- L 2
digenous to the off shore area of the site.
1 Fresh water mouusk found in the vicinity of tho' site are not con-1l 1
sumed by humans and are not a major component or level in the food chain if for no other reason other than the smau population due to l the unfavorable physical makeup of the lake bottom in the area.
j i Because these fresh water mouusk are not considered edible there is l' no dose to man from the presence of the Mn-54. Co-60, or Cs-137 4
concentrations. As in past years an estimate can be made using
! substituted parameters for the purpose of putting into perspective
the possible significance of Mn-54, Co-40, and Cs-137 concentrations i detected in the moHusk samples. Using the average individual
~~eensumption of seafood of 1.0 kg/ year for an adult, the dose result- !~~
l ing from ingestion of moHusks would be 0.00016 arem/ year to the !
whole body and 0.0015 mrem / year to the gastrointestinal trset for the maximum Mn-54 concentration of 0.11 pC1/g (wet). The dose resulting from the Co-40 concentration of 0.115 pC1/g (wet) would be 0.0005 mrom/ year to the whole body and 0.0046 arem/ year to the gastrointestinal tract. The dose resulting from the Cs-137 concen-tration of 0.022 pC1/g (wet) would be 0.0014 mrom/ year to the whole body and 0.00005 mrom/ year to the gastrointestinal tract. The total maximum dose that would be received from the consumption of 1.0 kg
of fresh water mouusk would be 0.00

28 mrom to the whole body and 0.00615 mrom to the gastrointestinal tract. This calculated dose is extremely sman and as noted above la reality would be equal to no dose, because of the sere consumption rate.
i !
The concentrations of Mn-54 and Co-60 have shown a significant (
l decline since 1978 when both radionuclides were detected at their I
! maximum level. The concentration of Mn-54 detected in the 1984 !
. samples shows a slight decrease from the 1983 values. The Co-60 concentration in the indicator samples showed a sman increase from the levels detected in 1983. Co-60 concentrations in mouusk samples
! have remained relatively constant since 1977. 3r-90 concentrations l in mouusk samples have revnsined stable since 1978 after a peak in 1976, with little change in the 1984 samples. Graphs of prevfous mouusk sample results for Mn-54 Co-60 and 3r-90 are presented in l Section VII. Also found in Section VII is a physical description of '
, I the lake bottom in the vicinity of the site for reference to the suit- i lt ability of the area for mouusk habitat. "

4. GAIS!ARUS - TABLE 4 GAMMARUS samples were conected three times during the 1984 sam-ple period in conjunction with mouusk, periphyton and bottom sediment. GAMMARUS are benthic or demersal dwouing organisms found in the general vicinity of the site and throughout Lake Ontario. GAMMARUS are sampled as an indicator organism whose major pndator is the local Ash population. GAMMARUS are generally found in periphyton and cladophora growth areas and are limited in .
their territorial ranges. Samples were collected at the control (00) locadon and at the NMPP (02) and JAF (03) transects. Sample col-lections were made over a two week period (or longer) in order to collect sufScient quantities of sample for acceptable analyses.
The first ecllection of GAMMARUS in the spring of 1984 (June 14, 1984 through June 29, Iss4) ytelded sample weights of only 1.7 g, 0.2 g, and 0.3 g nspectively for the Oswego, NMPP, and JAF tran-sects. It should be noted that GAMMARUS are normally less than 10 mm in size and require a large numoer to obtain a biomass of one gram of sample. The spring conection of GAM &fARUS is also usuany impeded by the cold lake water temperatures resulting in few GAMMARUS inhabiting the shoraune shallows. 4 These sman sample weights were insufScient for Sr-If and Sr-90 analysis, and yielded high analytical sensitivities for gamma spectral r analysis. The JAF sample resulted in sensitivities of less than ,
12.0 pCl/g (wet) for Co-40 and less than 11.0 pCl/g (wet) for Cs-137. The NMPP sample resulted in sensitivities of less than 18.0 pC1/g (wet) for Co-64 and less than 17.0 pCi/g (wet) for i Cs-137. The control sample (Gewego) resulted in sensitivities of ,
less than 4.4 pC1/g (wet) for Co-60 and less than 5.0 pCl/g (wet) for Cs-137. r Because of the smau quantities couacted in the spring GASDfARUS conection, which were insufScient for Sr-89 and Sr-90 anaaysts, another sample was attempted before the late summer couection.
This resample GA!!!.!ARUS conection started on July 18, 1984 and ended on August 17, 1984. This couection yielded sample weights of r 70.8 g, 57.5 g, and 52.6 g respectively for the NMPP. JAF, and Oswego transects. These sample weights were sufScient for good analytical sensitivities. This resample collection showed measurable concentrations of K-40 and Sr-90 only. K-40 was detected in au thne of the sample locations. E-40 is a naturany occurring radio-nuclide.
Strontium-90 was also detected in each of the samples conected in both the indicator and control samples. As noted previously, similar
, detections of Sr-90 won made In mouusk samples. Strontium-90 is l considered to be a background radionuclide because its origin is not e i related to the operation of the plant, but is attributed to fallout j l from stmospheric nuclear testing.
49
I .
l The analyses of the resample GAMMARUS collection showed no mes-surable concentrations of Co-60, cs-134, Cs-137 or any other plant related radionuclides.
The late summer (August 8,1984 through September 11,1984) col-lection of GAMMARUS also provided sufScient quantities of this organism for good analytical sensitivities. The late summer collection
, again only showed measurable concentrations of K-40 and Sr-90.
, Both K-40 and Sr-90 were detected at all three sample locations.
. ! The analyses of the late summer GAMMARUS samples also showed no I
~~measurable cencontrations of Co-60, cs-1J4, Cs-137 or any other~~
, plant related radionuclides.
j The absence of plant related radionuclides in GAMMARUS samples collected in 1984, and the lack of detectable concentrations from the previous years of 1980, 1981 (second collection only), and 1982 1
l indicate that the presence of these nuclides in GAMMARUS organisms is not routine nor chronic. The dose to man as a direct result of ecncentrations of cobalt and cesium would be zero as GAMMARUS is i not consumed by man. The importance of the activity in these organisms is only signiScant with respect to the passage of any radionuclides through the food chain to a trophic level which may impact man.
I Ristorical data for GAMMARUS sample results shows that the Sr-90 concentration for the controi location has steadily decreased since i 1977 and seems to be leveling off. . The Sr-90 concentration for the indicator locations also shows a downward trend and leveling, except for a peak in 1980. No dennite trend can be determined for Cs-137 concentraticns, however, as positive detections have been random in past years. Previous GAMMARUS data (Cs-137 Sr-89, Sr-90) is i presented in Section VI, HISTORICAL DATA.

~~.5. FISH - TABLE 5 l A total of 18 required Ssh samples were conected in the spring sea- !~~
son (June 1984) and in the fan season (October 1984). Conections l i i were made utilizing 301 nets at one offsite location greater than See i '
{ miles from the site (Oswego Harbor area), and at two onsite locations 4 in the vicinity of the Nine !, tile Point Unit il (02), and the James A. ,
l Fit: Patrick (03) generating facilities. The Oswego Harbor samples j served as control samples while the NMP (02) and JAF (03) samples
~~served as indicator samples. Samples were analyzed for gamma i emitters, Sr-89, and Sr-90. Data is presented in the ANALYT! CAL }~~
~
l RESULTS section of the report on Table 5.
Analysis of the 1984 Ssh samples contained detectable concentrations ,
of radionuclides related to past weapons testing and natural origins 1 i (naturally occurring). Sman detectable concentrations of Cs-137 . !
] were found in all Ssh samples (including control samples). Deteet-l able concentrations of K-40, a natursuy occurring radionuclide, were :
l also found in au fish samples conected for the 1984 program. j i l Spring f!sh conections were comprised of two separate species and , j nine individual samples. The two species represented one feeding 4 j
! type. Lake trout and brown trout are highly predacious and feed 8
on signiScant quantities of smaller Sah such as smelt, alewife, and 4 other smaller predacious species. Because of the limited availab!11ty 1 i of species present in the catches, no bottom feeder species were col- l
! lected in the spring samples.
1 i Cs-137 was detected in an onsite and offsite samples for both species t j conected. Cnsite samples showed Cs-137 concentrations to be slightly i greater than control levels for some samples and slightly less than i control levels for other samples. The concentrations detected are i not signiScantly different from the control results and are therefore i considered background. Cs-137 in lake trout samples ranged from 0.033 to 0.037 pC1/g (wet) and averaged 0.035 pC1/g (wet) for the indicator samples. Cs-137 in the control sample was 0.037 pC1/g i (wet) for lake trout. Cs-137 in brown trout samples ranged from i
! 0.039 to 0.055 pct /g (wet) and averaged 0.048 pCi/g (wet) for the j indicator samples. Co-137 in the control samples ranged from 0.031 ,
j to 0.032 pct /g (wet) and averaged 0.032 pct /g (wet), j i 1
j K-40 was detected in an of the spring samples conected. K-40 !s a -

smallmouth bass, and white sucker) ranged from 2.7 to 3.5 pC1/g i; (wet) and 3.1 to 3.4 pC1/g (wet) for the control samples. No other radionuclides were detected in any of the fall fish samples. -

i {
i t Review of past environmental data indicates that the Sr-89 and Sr-90 1 l concentrations have decreased steadily since 1976 for both the indi- l 1 cator and control locations to the present 1994 LLD '.evels. A i general decline in detectable Sr-89 and Sr-90 results is most prob- i I ably due to the result of the incorporation of these radionuclides i with organic and inorganic substances through ecological cycling. In addition, Sr-89 has a relatively short half-life of 52 days.
l The mean 1984 Cs-137 concentrations have decreased alightly from 1981 for the indicator samples and significantly from 1980 to 1976. ,

i i (wet) in 1976 to a level of 0.043 pC1/g (wet) in 1984. Contro ,
l sample results have also decreased from a level of 0.13 pCl/g (wet) '
I in 1976 to a level of 0.033 pC1/g (wet) in 1984. Results from 1979 1
, to 1984 have remained fairly consistent.

i As noted for Sr-89 and Sr-90 above, the gereral decreasing trend for Cs-137 is most probably a result of ecological cycling. A signift-cant portion of Cs-137 detected since 1976 in fish is a result for i
l i
weapons testing fallout, and the general downward trend in concen-trations wi!I continue as a function of ecological cycling and nuclear decay.

! t Lake Ontario fish are considered an important food source by many, therefore, fish is an integral part of the human food chain. Based '
i on the importance of fish in the local diet, a reasonable estimate of dose to man can be calculated. Assuming that the average adult l consumes 6.9 kg of Sah per year (Regulatory Guide 1.109) and the I t fish consumed contains an average Cs-137 concentration of 0.043 ;
j pC1/g (wet) (annual mean result of indicator samples for 1984), the l'
whole body dose received would be 0.021 mrom per year. The criti- ,
cal organ in this case is the liver which would receive a calculated
dose of 0.032 mrom per year. No doses are calculated here for l Sr-89 and Sr-90 since these radioisotopes of strontium were not detected during 1934. The Cs-137 whole body and critical organ doses are conservative calculated doses associated with consuming l, '
=
sh from the Nine Mile Point area (indicator samples).
Conservative whole body and critical organ doses can be calculated 'i
~~for the consumption of fish from the control location as well. In this j case the consumption rate is assumed to remain the same (6.9 kg per~~
year) but the average annual Cs-137 mean concentration for the con-l trol samples is 0.032 pC1/g (wet). The calculated Cs-137 whole body l'
, dose is 0.016 mrom per year and the associated dose to the liver is '
O.024 mrom per year.
I In summary, the whole body and critical organ doses observed as a i result of consumption of fish is small. Doses received from the consumption of indicator and control sample fish are approximately the same with the dose from control samples being slightly lower.
j Doses from both sample groups are considered in the range of back-ground exposure rates.

1984 lake water samples were analyzed monthly for gross beta and gamma emitters (using gamma spectral analysis). Sr-59, Sr-90 and l i
tritium analyses were performed quarterly. Quarterly samples (i.e., i i Sr-89, Sr-90, and tritium) were composites of monthly samples. j I
l The analytical results for the 1984 lake water sample program showed no evidence of plant related radionuclide buildup in the lake water in
~~the vicinity of the site. Indicator samples were collected from the inlet canals at the Nine Mile Point Unit #1 and James A. F1t Patrick l~~
l
. facilities. The control location samples were collected at the City of r i Oswego water treatment plant and consisted of raw lake water prior j to treatment.
The gross beta annual mean activity for the . indicator sample loca-tions Nine Mile Point Unit #1 and the James A. FitsPstrick inlet i ennata (3.98 pct / liter) was slightly higher than the 1963 mean inlet :
! I canal results (3.34 pct / liter). The Nine Mile Point Unit #1 canal j samples were greater than the control samples for eight of the 12
~~i monthly samples analyzed and ranged from 2.20 pC1/ liter to 5.30 i ,~~
pC1/Hter. The James A. Fit: Patrick canal samples were greater than
' the control samples for seven of the 12 monthly samples analysed and
! ranged from less than 2.2 pct / liter to 5.90 pC1/11ter. The control I sample results ranged from 2.40 pct / liter to 5.20 pct / liter. The i Guetuation in the groes beta canal sample results is due to the i natural variation in concentration of naturally occurring radio- i nuclides. l A reduction in gross beta activity since 1974 is primarily the result l of improved analytical procedures and equipment and not necessarily l l i to changes in plant operations. Although the past elevated gross
! beta concentration may be due in part to past weapons testing, it is j difScult to determine what portion was due to improved instrumenta-
! tion and what part was due to weapons testing. There were no sig-
~~niScant changes or trends in gross beta activity on a monthly basis i for 1984. (See historical data graphsSection VII.)~~
Gamma spectral analysis was performed on 34 monthly composite sam- l ples required by the Environmental Technical SpectScotions. Only ;
one radionuclide was detected in the inlet canal samples. This radionuclide is naturally occurring and not plant related, j K-40, a naturally occurring radionuclide, was detected intermittently in both intake canals and the raw city water supply. K-40 was
o detected in two of the 12 monthly inlet canal samples at the James A. ;
l Fit: Patrick inlet canal and ranged from 7.2 to 13.2 pct / liter. The l' i o Nine Mile Point Unit 41 inlet canal samples also showed K-40 detected
! in two of the 12 monthly samples. The concentrations ranged from
! 14.4 to 14.5 pC1/11ter. K-40 in the Oswego efty water supply was i detected in four of the 12 monthly samples, and ranged from 7.6 to l 15.0 pC1/ liter.

& i Quarterly samples for Sr-89 analysis were composites of the =enthly samples. Sr-89 was not detected in any of the water samples taken from the City of Oswego water treatment plant the James A. Fitz-Patrick inlet canal, or the Nine 5111e Point inlet canal. The lower '
limit of detection values for the City of Oswego water treatment plant canal samples (control location) ranged frem less than 1.10 pC1/11ter to less than 2.00 pCl/ liter (LLD). The lower limit of detection val-ues for the indicator (James A. FitzPatrick inlet canal and Nine Stile Point inlet canal) locatiens ranged from less than 1.20 pCi/ liter to less than 2.00 pCl/ liter (LLD).
Quarterly samples for Sr-90 analysis were ecmposites of the monthly samples as noted for the Sr-89 analysis. Sr-90 was detected in two of the four quarterly composites at both the James A. FitzPatrick and Nine 5111e Point Unit di inlet canals. Sr.90 was detected in only one of the four quarterly composites at the City of Oswego water treatment plant or contml location. At the control location, the Sr-90 concentration was 0.72 pC1/11ter. Sr-90 in the Nine Stile Point inlet canal samples ranged from 0.56 to 1.30 pC1/ liter and showed a mean value of 0.93 pC1/Ilter. The James A. FitzPatrick inlet canal ,
samples showed Sr-90 ranging from 0.80 to 0.88 pCl/ liter and a mean value of 0.83 pC1/ liter. Sr-90, as detected in the 1984 water sam-ples, is considered to be background S r-90 as a result of. past weapons testing.
Tritium samples, as noted above for Sr-89 and Sr-90, are quarterly samples that are a composite of the appropriate monthly samples. l Tritium was detected in six of the eight indicator samples and two of I the four control samples. The City of Oswego water treatment plant showed tritium concentrations ranging imm 190 pC1/ liter to 220 pCi/11ter with a mean of 205 pC1/11ter. Tritium concentrations for the James A. FitzPatrick inlet canal ranged from 110 pC1/11ter to 370 pC1/11ter and sho ved a mean concentration of 230 pC1/11ter. Inlet ,
canal samples taken at Nine at11e Point showed tritium concentrations ranging from 230 pCilliter to 340 pC1/11ter. The annual mean concen-t stion was 235 pC1/11ter.
Evaluation of past environmental data shows that gross beta concen-trations in water samples have decreased significantly since 1977 at both the indicator sample locations (inlet canals) and at the control Iccation (Oswego city water). As noted previously, however, the decrease is primarily a result of superior analytical instrumentation.
Since 1978, gross beta levels have remained relatively constant at both indicator and control locations. Indicator annual means ranged from 15.8 pC1/11ter in 1977 to 41.8 pC1/11ter in 1976. For the period of 1978 through 1983, annual means ranged from 2.73 pC1/11ter (1982) to 4.53 pC1/11ter (1978). The indicator annual mean for 1984 was 3.98 pC1/llter. Control annual means also were reistively high during 1975 to 1977. During these years, the concentrations ranged form 45.33 pC1/11ter (1975) to 10.9 pC1/11ter (1977). Data from 1974 for the control !ccation was deleted from this comparison because of questionable results. For the period 1978 through 1983, annual mean i
i is
i gross beta concentration ranged from 2.42 pC1/11ter (1982) to 3.55 pCilliter (1978). The control annual mean for 1984 was 3.41 pCi/11ter.
Review of previous data for Sr-89 demonstrates that results have been variable since 1975. Sr-89 for the indicator samples has ranged from not detected (1976,1977,1979,1983, and 1984) to 0.78 pCi/ liter (1981) and has been at relatively constant levels when detected. At the contml locations. Sr-89 ranged from not detected I (1975-1978, 1981, 1983, and 1984) to 1.4 pC!/ liter (1980). During
1984, Sr-89 showed an annual mean of less than 1.60 pCilliter (LLD) at the control location and less than 1.68 pC1/11ter (LLD) at the indicator location. S r-90 annual means have remained relatively consistent at both indicator and control sample locations since 1975.
~~Mean results for the indicator samples ranged from not detected (1975 and 1976) to 1.08 pC1/11ter (1982). Mean results at the control~~
~~sample location ranged from not detected (1975-1978) to 2.04 l~~
pC1/11ter (1982). The 1984 annual mean St-90 results for the indi-cator samples and control samples were 0.88 pC1/ liter and 0.72 pC1/11ter respectively.
I Previous annual mean results for tritium at the indicator sample location has decreased slightly since 1976, with the exception of i 1982. Sample results were available since 1974 through 1984 and j showed a peak value of 641.0 pC1/ liter (1982) and a minimum value of 234.0 pC1/11ter (1979). The annual mean tritium result at the indicator Iccations for 1984 was 282.0 pC1/11ter. This is a slight
! decrease from the value detected in 1983 (317.0 pC1/ liter).
l Mean tritium results at the control location have also decreased slightly since 1976. Mean annual results were available for 1974 through 1984. These results show that tritium at the control loca-tion ranged from not detected (1974) to 651.7 pC1/ liter (1976). The annual mean tritium result at the control location for 1984 was 205.0 pct / liter. This is a slight decrease from the 1983 value of 250.0
, pC1/11ter. The fact that tritium is a naturally occurring radioactive isotepe of hydrogen which is produced in the upper atmcsphere by cosmic radiation, as well as a product of reactor operation, accounts for the background level in the lake to vary slightly from year to year.
The impact. as exprested by a dose to man, is not assessed here since the primary pathway, in this case, is drinidng water. The nearest source for drinking water is the City of Oswego water treat-ment plant which is the control location for the sampling program.
The results of the control location are consistent with previous years' results and are representative of normal background radienu-clide concentrations in take water and regional drinking water that might be affected by the site.

~~1. AIR PARTICULATE CROSS BETA - TABLES 9 and 10 Tables 9 and 10 contain the weekly air particulate gross beta results .~~
for the six offsite and nine onsite sample locations. The samples are counted at a minimum of twenty-four hours after collection to allow for the decay of naturally occurring radionuclides with short half-lives. A total of 312 offsite and 462 onsite samples were collected and analyzed during 1984. No significant levels of gross beta activ-ity were observed in any of the samples. The offsite or control '
mean concentration for 1984 was 0.026 pCf/m3 while the indicator or l onsite sample mean was equal to 0.025 pC1/m8 As noted, the onsite mean is about five percent lower than the offsite mean for the same sample period. This difference in mean concentration has been ex-l hibited in the past 10 years with the exception of 1977 when a higher annual mean gross beta activity was observed for the onsite sampling stations. In these 10 years, the control stations' annual mean ranged from a minimum difference of 5.0 percent higher than .
j the indicator observed in 1984 to a maximum difference of 28.6 per- !
cent higher, observed in 1978. The difference in offsite and onsite weekly and monthly mean values for gross beta could be the result ;
of a combination of the many natural processes which can affect en- '
I vironmental concentrations. The most significant parameter that could possibly contribute to a depressed or lower concentration for
the onsite stations would be location. The close proximity of onsite sampling stations to the lakeshore (Lake Ontario) would account for lower concentrations of naturally occurring radionuclides being col-1ected on the sampling media. Surface winds from off the lake would I contain less particulate matter and airborne gases than surface winds 2
from adjacent land anas. The major component of gross beta con-centrations are decay or daughter products of uranium and thorium
. and potassium-40. The concentrations of these nuclides in the j ground level atmosphen are dependent upon the local geology and its chemical constituents. Thus surface winds of terrestrial origin have a potential for containing higher concentrations of naturally oc-curring radionuclides.
The observed inenases and decreases in general gross beta activity !
can be attributed to changes experienced in the biosphere. As l discussed above, the concentrations of the naturally occurring radio- "
nuclides in the lower limits of the atmosphere directly above the ter-restrial portion of the earth are affected by time related processes i such as wind direction. snow cover, soil temperature and soil mois-ture content. Very little change was noted in gross beta activity which cornsponded with seasonal changes as has been observed in past years.
n In general, gross beta activity in air samples has decreased signift-cantly. The mean 1984 concentration for both offsite and onsite is six times lower than the mean concentration detected in 1981. This overall reduction in activity is directly att:ibutable to the increased activity detected in 1981 as a result of fallout from an atmospheric nuclear test and subsequent return to background levels in 1983-84.

Co-60 release rates were well within four percent of the design objective of the plant as outlined in Section 2.3.B.2 of the Environ-mental Technical Specif! cations. These licits were consistent with past effluent rates when Co-60 was not detected.
Investigation of the occurrence demonstrated that the unused particu-late filters were contaminated during handling prior to the installa-tion of the filters in the environmental monitoring stations (refer to the 1983 report for a more detailed account of the investigation).
The investigation concluded in early March of 1984 and corrective action was implemented at that time. It was concluded in the 1983 report that the March 1984 ccmposite samples and subsequent samples could confirm the conclusions of the investigation. The results of the 1984 air particulate samples confirmed the results of the investi-gation.
During the months of January and February 1984, Co-60 was detected in both onsite and offsite composite samples. The concen-trations detected were comparable to the December 1983 results.
During March of 1984, Co-60 was detected only in the onsite compos-ites. Co-60 was not detected in either onsite or offsite composite I samples for the remainder of 1984 ( April through December). It is believed with reasonable confidence that the December 1983 and January through March 1984 positive results for Co-60 were the result of contamination during handling prior to installation in the environment.
Assessment of the presence of fission product radionuclides in air particulate composite samples can be depicted by calculating doses to man as a result of inhalation. Co-60 and Cs-137 were the two fission product radionuclides detected in 1984. It was noted previously, however, that the presence of Co-60 was attributed to contamination during handling prior to actual field use. For the purposes of illustration, however, dose calculations can be performed assuming that the Co-60 results were actual f!ald measurements.
Using the average adult inhalation rate of 8,000 m8/ year or l
667 m8/ standard month (Regulatory Guide 1.109), and the mean con-centration measured at the onsite sample stations, the following yearly doses can be calculated based on the amount of time the ra-dionuclide was detected during the year:

, sampling stations are composited monthly by location (onsite/offsite).
! Each ecmposite is analyzed for gamma emitters using gamma spectral analysis.
l l The results for the 24 monthly samples analyzed for the 1984 pro-I gram showed positive detections for four radionuclides. Those radionuclides detected were Co-60 and Cs-137, in addition to Be-7 and K-40 which are both naturally occurring radionuclides. The four radionuclides measured in the 1984 composite saroles can be I divided into two categories, the first category is naturally occurring radionuclides. Be-7 was detected in each of the 24 composite sam-ples both onsite and offsite. The mean value for Be-7 concentra-tions was 16 percent higher in the offsite composite samples than the onsite samples. Potassium-40 was detected in nine of the offsite and j ( onsite monthly composite samples. The offsite annual mean was 21 ,
j
~
percent higher than the onsite annual mean for K-40. '
i a ,
The second category of radionuclides detected are those which are l plant related. Included here are Co-60 and Cs-137. Cs-137 was
' included here due to the fact that the Cs-137 may be a constituent of plant effluents. A review of 1984 Cs-137 sample data indicates
! that Cs-137 is most likely the result of past weapons testing and i subsequent environcantal levels of Cs-137 from fallout. Cs-137 was I not detected in any of the offsite composite samples, but was de-i tected in one of the onsite composite samples. The concentration of This Cs-137 in this one onsite composite sample was 0.00018 pCi/m8 can be compared to the LLD level of Cs-137 (less than 0.00018
, pC1/m8) in the offsite composite sample from the same month. Co-60 i was detected in three of the 12 onsite monthly composite samples and I i two of the 12 offsite monthly composite samples. The onsite Co-60 concentrations ranged from a maximum of 0.00149 pC1/m8 in February to a minimum to 0.00054 pC1/m8 in March of 1984. The mean Co-60 i concentration for the onsite samples was 0.00117 pC1/m8 The offsite j } Co-60 concentrations ranged from a maximum of 0.00107 pC1/m8 in January to a minimum of 0.00038 pC1/m8 in February of 1984. The
{ mean Co-60 concentration for the offatte samples was 0.00073 pC1/m8 l
l The presence of Co-60 has been noted in the past and can be a ,
result of weapons testing, contamination during handling, and oper-I ations at the site.
The detectable Co-60 concentrations found during the months of January through March of 1984 in both onsite and offsite composite I samples was a result of contamination during handling. The 1983 i Annual Environmental Operating Report noted that during the month of December 1983, a marked increase in Co-60 concentrations was noted in both onsite and cffsite composite samples. The detected i concentrations were inconsistent with operations at the site. A l review of plant gaseous effluent data for this period showed that the l

During the 1984 sampling program airborne radiciodine was not de- '
tected in any of the 312 weekly samples collected from the six offsite sampling stations. In the 1,871 weekly offsite I-131 samples collected in 1979 through 1984, 1-131 was only detected once (June 16, 1982).
Offsite I-131 detections were also made in 1977 and 1978.
1-131 was also not detected in any of the 464 onsite samples analyzed in 1984. I-131, however, has been detected in the past at the ensite sample tocations. In the 2,805 weekly onsite I-131 samples collected in 1979 through 1984, I-131 was detected in only 23 samples.
The end result of the 1934 I-131 sampling effort showed no signifi-cant impact due to the operation of the plant. Also during 1984, I-131 was not detected in any other environmental sample media including mi!k and green leafy vegetables.

The above table illustrates that the average calculated dose to man from plant related radionuclides is very small and of little biological l signiScance.
1 For the purpose of illustration, the signiScance of the above doses can be brought into perspective by a comparison to the average annual population lung dose received frorn the combustion of natural gas used in cooking ranges and unvented heaters. This average an-nual population lung dose ranges from 2.0 mrem /yr to 5.0 mrem /yr j (NCRP, No. 56). This represents a dose approximately 3,000 times
' greater than that received from plant effluents as noted above.

As observed, the site boundary dose based on two available TLD lo-cations was less than the average offsite dose for each of the four quarters in 1984. This is probably due to the difference in ground i dose rates which are indicative of variable concentrations of natural-ly occurring radionuclides in soil and rock such as rodium, uranium, thorium, and potassium. The difference could also result from sta-tistical variation in the TLD readings, as the site boundary dose is based on a population of only eight individual readings per quarter !
. (two TLD's).
TLD numbers 31 and 39 are Iccated within the Nine Mile" Point il re- {
stricted area near the radwaste facility and are influenced by the close pr ximity to the building. TLD numbers 27 through 30 and 47 are loca wi within the restricted area of the James A. FitzPatrick radwaste 'acility and are influenced by the radwaste buildings. TLD number 59 is located near the restricted area of the MtzPatrick Plant stack and is influenced by the proximity to this structure. TLD numbers 3 and 4 are located at the construction site of Nine Mile Point #2. TLD's are subject to radiography at the Unit 42 site and l to a much lesser extent the FitzPatrick facility.
Offsite TLD results remained fairly consistent for most TLD locations i each quarter. Any slight variations in natural background radiation levels that were observed are most probably a result of increasing or decreasing emission rates for radon and thoron gases emanating from {
the ground. These emission rates are related to ground moisture +
content and other natural parameters.
Onsite TLD results remained fairly consistent except for TLD's '
located near radwaste facilities which may be affected by the fre-quency of radwaste processing and shipment. These TLD's include numbers 23, 24, 27, 28, 29, 30, 47, 48, and 61 at the James A. I FitzPatrick facility and number 39 at the Nine Mile Point il facility, i TLD numbers 3, 4, 41, and 62 are located at the Nine Mile Point #2 facility and were affected by the frequency of radiography at the construction site. Radiography is a common practice at construction sites in order to determine the quality of equipment welds such as pipes. TLD's located in areas near radiography work will show fluctuating doses as the amount of radiography performed is not con- '
sistent. TLD number 59 results were variable as a result of the operating mode of the James A. FitzPatrick facility. This TLD is located near the James A. FitzPatrick facility exhaust stack. ,

~~4. TLD (ENVIRONMENTAL DOSIMETRY) - TABLE 14~~
TLD's were collected once per quarter during the sample year. The l* TLD results are an average of four independent readings at each lo- i cation and are reported in mrem per standard month. In 1984. TLD's for the most part were collected approximately on March 31, 1984, June 30, 1984, September 28, 1984, and January 4,1985.
t ll TLD results are organized into three groups for reporting purposes, r
The groups are onsite TLD's (defined as TLD's in the immediate i proximity of the individual facilities, at points of interest), environ-mental station TLD's (a ring of TLD's surrounding the generating facili. ties as a group), and offsite TLD's (TLD's located cff the site property or controlled area and ranging up to 20 miles from the
! site) .
A net dose at the environmental station TLD's can be calculated sim-ply by subtracting the mean standard month offsite doses from the mean standard month onsite environmental station doses *. Environ-i mental station TLD's are arranged in a concentric circle and range in
! distance from the individual facilities from 1,500 to 2,000 feet. The i net dose per mean standard month for each quarter is as follows:
Quarter Net Environmental Station Dose **

! The annual site property boundary dose for 1984 cannot be deter-i mined from the not environmental station dose since the property boundary extends out to approximately 0.75 miles from the site (i.e., beyond the concentric circle of environmental station TLD's).
j ,
j A general estimate can be made based on two available TLD's located at the site boundary. The not dose per standard month for each quarter can be calculated for these two locations (TLD numbers 19 and 15) east and west of the site. This calculation is conservative since it represents the shortest distance to populated areas. ;

The grazing season is considered to be Stay through October. Two of the sample locations, numbers 5 and 45, were deleted from the milk sampling pmgram as a result of the 1984 spring milch animal census. These locations were deleted in July. Sample location number 60 was added to the milk sampling program in July as a result of the 1984 spring milch animal census. Sample location descriptions are listed below. ;
Location No. Direction frem Site Distance from Site (miles) 4 ESE 7.7 5 SSE 7.2 7 ESE 5.5 16 5 5.2 40 SW 15.3 45 SE 8.1 50 E 8.2 55 E 9.0 60 E 9.5 Stilk samples were collected from each of the locations in the .frst half of the month and analyzed for 1-131. At approximately mid conth, a second mHk collection was made at the same locations. The second collection was composited with an equal aliquot from each location sampled during the first coHection. The composite samples were analyzed for gamma emitters and Sr-90. I-131, gamma isotopic, and Sr-90 results are fcund in the analytical results section.
The gamma spectral analysis of the monthly composite samples showed K-40 to be the most abundant radionuclide detected in the milk sam-ples collected in 1984. K-40 was detected in every sample analyzed and ranged in concentration from 1,840 pCi/ liter to 1,040 pC1/ liter at the indicator locations and 1,500 pCilliter to 1,190 pCi/ liter at the control location. K-40 is a naturally occurring radionuclide and is found in many of the environmental medias sampled.
Sr-90 was also detected in all of the 58 milk samples coHected during 1984. The mean Sr-90 concentration for the control location was 2.14 pC1/11ter. The mean for all indicator locations (within 10 miles of the site) was 2.34 pCI/ liter. The control and indicator sample means are similar. Sr-90 results for the indicator locations ranged from 7.60 pC1/ liter to 0.80 pCi/ liter. Control sample results ranged from 2.90 pC1/11ter to 1.30 pC1/11ter. The detection of Sr-90 in indicator and control locations at similar concentrations is indicative of back- ,
ground Sr-90 as a result of past weapons testing. j I

5. RADIATION MONITORS - TABLE 15 l' Environmental radiation monitors are located in 10 of the 15 air monitoring environmental stations. Each of the onsite environmental monitoring stations contains a radiation monitor and, in addition, the C offsite =onitoring station contains a similar monitor.* The radia-l tion monitors consist of a GM detector with an associated power supply, chart recorder, and trip unit. The monitor has an oper-ating and recording range from 0.01 to 100 mrem /hr. Each radiation 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 fmm the site. The monitors are not considered to be
, capable of high sensitivity environmental monitoring and do not detect minute fluctuation in levals of background radiation. Because of the relatively low sensitivity of the monitors (environmentally speaking) no ecmparisons are made between the radiation monitor i readings and the readings from environmental TLD's.
i
Due to repeated vandalism to C offsite environmental sampling station (the monitor detector was stolen several times), the radiation monitor was moved to D-1 offsite environmental sampling station on July 19,13' ..

i The impact as a result of Cs-137 in 1984 milk samples is insignificant I since no Cs-137 was cetected during the 1984 milk sampling program.
i The impact, as a result of Sr-90 in milk, due to plant operation, is j extremely small if any since the mean result of the indicator results and the control results are approximately equal considering fluctua-tions in the background levels. The levels of Sr-90 dete:ted in ;
indicator as well as control samples is considered to be representa- l tive of background concentrations. In this regard, the resultant calculated doses would be approximately equal.
Iodine-131 was not detected in the 58 monthly milk samples analy:ed for the 1984 program. No doses to man have been calculated due to the lack of positive detection. The detr.ction of I-131 in milk sam- l ples has not been routine in the past. In past sampling programs, j
, I-131 has been detected in milk samples in conjunction with fresh fallout from atmospheric nuclear testing.
l Graphs of yearly milk sample results for Cs-137 Sr-90 and I-131, I
along with monthly (1984) Cs-137 results by station, are presented in Section VII. ;

8. HUMAN FOOD PRODUCTS - TABLE 20 Human food product samples were cociprised of meat, eggs, poultry, and vegetables. Conections for meat, poultry, and eggs were made in the spring and fan seasons. Samples of produce included vegeta-bles with an attempt to sample at least one green leafy vegetable from each location. The ecliection of produce was performed in late summer or early fall. Three indicator locations were sampled for l each type of media ecuected, in addition, a control location was sam- j pied during each conection period. Indicator samples were conected within a 10 mile radius of the site in areas which would have a high potential for demonstrating possible effects of site operations. The ultimate factor controUing sample locations was the availability of required samples. Attempts were made to maintain prior sample loca-tions where possible.
Meat Spring meat conections were made at one offsite location (greater than 10 miles from the site) and at three onsite locations (less than .
10 miles from the site). Spring meat conections showed detectable concentrations of K-40 in aH samples. K-40 concentrations ranged .
from 2.6 pct /g (wet) to 3.7 pC1/g (wet). K-40 is a naturaHy occur- j ring radionuclide. Only one of the four spring meat samples showed detectable concentrations of Cs-137. The detected Cs-137 concentra-tion was in the indicator or onsite sample. The Cs-137 result for i this sample was 0.046 pC1/g (wet). Cs-137 was not detected in the i control sample.
Cs-137 is detected in many environmental samples and is usuaHy most prevalent in meat and fish, with respect to all the sample media ecliected. Cs-137 in meat samples is essentiaHy a result of past weapons testing. Cesium is incorporated into meat tissue from feed '
sources. The results detected in the spring meat samples are very ,
low concentrations and thus can appear in some samples and not in others. By review of the 1981 spring meat sample data, it is noted ,
that Cs-137 appeared in the control samples (0.017 pC1/g (wet] and l 0.024 pC1/g (wet]). Cs-137 was also found in the control sample during 1980 (0.01 pC1/g (wet]).
The one meat sample that showed a detectable concentration of Cs-137 (0.046 pCilg (wet]) was slightly higher than the detected concentrations in control sac 2ple results during the spring of 1981.
Because this result (0.046 pC1/g (wet]) is sman, the impact or dose as a result of this concentration is insignificant and is addressed below.
No other radionuclides were detected in the spring meat samples i using gamma spectral analysis.
Fan meat conections were made at one offsite and at three onsite sample locations. The fall sac:ples showed detectable concentrations of K-40 in au samples. K-40 concentrations ranged from 3.6 pC1/g (wet) to 2.9 pCilg (wet).

! 7. MILCH ANU!AL CENSUS - TABLE 19 The milch animal census is an estimation of the number of cows and i goats within a 10 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 pre-1 '
vious milch animal owners and also by road surveys to locate any i possible new owners. Questionnaires not responded to are followed up by telephone calls.
The number of milch animals located within the 10 mile radius of the site was estimated to be 1,080 cows and three goats for the spring 1984 census. One new location was found since the summer 1983 census. The number of cows decreased by 133 and the number of goats increased by three with respect to the 1983 summer census.
The 1984 summer census showed a total of 1,064 cows and one goat.
No new locations were found since the spring 1984 census. The number of cows decreased by 16 and the number of goats decreased by two with respect to the 1984 spring census.

Egg samples were collected in the spring (5 lay 2-10 June 6,1984) and in the fall (October 26, November 5-20, 1984). Samples were !
collected at three onsite locations (within 10 miles of the site) and at one offsite location (greater than 10 miles from the site). The only radionuclide detected during 1984 in egg samples was K-40. K-40 was detected in the spring samples at concentrations that ranged from 1.0 pCilg to 1.2 pCi/g (wet). The fall samples showed K-40 concentrations that ranpd from 1.1 pC1/g to 1.3 pC1/g (wet).
Poultrv ,
Poult.7 samples were taken during the spring (?. fay 2-10, June 6, 1984) and during the fall (October 26, November 5-20, 1984) at three onsite locations and one offsite location. The only radionuclide detected during 1984 in poultry samples was K-40. K-40 was de-tected in the spring samples at concentrations that ranged from 3.0 to 3.8 pCI/g (wet). The fall samples showed K-40 concentrations that ranpd from 2.6 to 3.7 pC1/g (wet).
Fruits and Vegetables Fruits and vegetables were obtained during the harvest secson. Co!-
lections were made during September at three indicator locations and one control location. A successful attempt was made to collect one broadleaf and one non-broadleaf fruit or vegetable at each location.
Broadleaf vegetables of cabbage, Swiss chard, and collard greens and non-broadleaf fruits and vegetables of tomatoes and squash were collected.
K-40 was detected in all broadleaf and non-broadleaf vegetables and fruits. Broadleaf vegetables (Swiss chard, cabbage and collard greens) showed concentrations of K-40 ranging from 1.8 pC1/g to 5.1 pC1/g (wet). An indicator sample had the highest concentration (5.1 pC1/g (wet]). Non-broadleaf fruits and vegetables showed concen-trations of K-40 ranging from 1.8 to 2.2 pCI/g (wet). Again an indicator location had the highest K-40 concentration (2.2 pC1/g (wet]) .
Be-7 was detected at the control sample location in Swiss chard.
The detectable concentration of Be-7 was 0.41 pC1/g (wet). The concentration of Be-7 at the indicator sample location for Swiss chard was less than 0.15 pC1/g (wet).
No other radionuclides were detected in the 1984 collection of fruits and vegetables.

i Cs-137 was again only detected in one of the four fall meat samples.
< The one meat sample that had a detectable concentration of Cs-137
, was an indicator sample (less than 10 miles from the site). The l i detectable concentration of Cs-137 was 0.032 pC1/g (wet) and can be compared to the control sample result of less than 0.027 pCilg (wet). This result is a very small concentration and, as noted above
~~j for the spring samples, is comparable to concentrations detected at~~
! control locations during 1981. These 1981 samples showed control i
Cs-137 concentrations of 0.017 and 0.024 pC1/g (wet) respectively.
3 The impact of these sman concentrations is discussed below.
No other radionuclides were detected in the fan meat samples using gamma spectral analysis.
i The detection of Cs-137 in meat samples has been noted for an years since 1978 for indicator samples and since 1980 for control locations (control samples were not conected prior to 1980). The detected !
concentrations since 1978 at the indicator locations have been fairly ,
consistent. These samples ranged from 0.021 to 0.039 pCi/g (wet). ;
j At the control locations, Cs-137 ranged from 0.01 to 0.021 pC1/g l (wet) . The indicator sample annual mean results have been slightly t higher than the control sample annual mean results.
The historical detection of Cs-137 in meat at control and indicator l sample locations is an indication of cesium production from weapons li testing. During 1984 Cs-137 was not detected at the control sample locations although Cs-137 has been detected in the past (1981 for i example) at control sample locations. As noted above, the concen-trations detected are very small and the impact or dose to man is insignificant. An average annual dose to man can be calculated as a result of meat consumption from within 10 miles of the site (indicator
~~sample results).~~
~~The average Cs-137 concentration in meat during 1984 was 0.039~~
~~, pC1/g (wet). Assuming an adult consumption rate of 95 kg per year l '~~
(Regulatory Guide 1.109), the annual dose to the whole body is l O.265 mrem per year. The critical organ dose is 0.404 mrem per year to the liver. This calculated dose is small and can be compared to an annual dose of 20 mrem per year to the critical organ (the
! gonads in this case) as a result of naturally occurring K-40 in the environment. The calculated whole body dose (0.265 mrom per year)
.' and the calculated critical organ dose (0.404 mrom per year to the '
l l Ifver) can also be compared to the dose received from control sample I results during 1981. During 1981, the annual mean concentration for i
the control meat samples was 0.021 pC1/g (wet). Using the same l consumption factor of 95 kg per year, the annual whole body dose
[
was 0.142 mrom per year and 0.217 mrom per year to the liver l (critical organ dose). As noted above, the 1984 control samples did not show any Cs-137 above the lower limits of detection. However, Cs-137 in meat has historically been present. Because of the small concentrations noted here, cesium can be noted in some samples and not in other samples.

CONCLUSION .
The Radiological Environmental Monitoring Program is conducted each year to determine the radiological impact of the James A. FitzPatrick Nuclear Power Plant on the local environment. As demonstrated by the analytical results of the 1984 program, the major radiological impact on the environ-ment was the result of fallout from atmospheric nuclear testing.
Levels of natural background and the associated fluctuation in intensity are much more significant in terms of dose to man (normal background in the vicinity of the site is equal to 60 mrem /yr) than radiation levels in the environment associated with the operation of the plant. ,
Using the data presented in this report, and earlier reports as a basis, it can be eencluded that no appreciable radiological environmental impac*. has resulted from the operation of the James A. FitzPatrick Nuclear Power Plant.

r 8. The spring coIIection of GAMMARUS did not contain sufficient quanti-I ties for Sr-89 and Sr-90 analysis as required by Table 4.3.1, Appen-dix B of the James A. FitzPatrick Nuclear Power Plant Environmental Technical Specifcations. As required by plant procedures, three l attempts were made to obtain sufficient quantities of GA&STARUS for i analysis. The unavailability of GAMMARUS is most probaciy due to the unseasonably cold temperature of Lake Ontario and the delay of the spring lake turnover. Few GAMMARUS were inhabiting the shoreline shallows during the spring sampling season. Another sample collection of GAMMARUS will be attempted before the second sample collection in late August.
9. Environmental radiation monitor J onsite was inoperable from July 16, 1984 (0001 hours1.157407e-5 days 2.777778e-4 hours 1.653439e-6 weeks 3.805e-7 months ) to July 19,1984 (1334 hours0.0154 days 0.371 hours 0.00221 weeks 5.07587e-4 months ). Inoperability was caused by vandalism to the environmental station (the monitor de-tector was stolen).
