NINE MILE POINT UNIT 1 ANNUAL ENVIRONMENTAL OPERATING REPORT I ~ INTRODUCTION This report is submitted in accordance with Appendix B, Section 4~ 6.l.a to DPR-63, Docket No. 50-220 '

I ~ DESCRIPTION The r equi ed sample collection and analysis schedule for QG' 1 is listed in Table 1 and 2 ~

The sample collections for the radiological program are performed by two g oups. Ecological Analysts Incorporated (EAI) performs much of the environmental sampling. EAI is presently performing the Nine Mile Point Aquatic Ecology Study at the site. The staff equired by EAI to perfozm this study is used to perform the terrestrial sampling required for the site Radiological Envi onmental Monitoring Program (REMP) ~

Zn-plant canal sampling and emaining terrestrial sampling is performed jointly by the NMPNS and JAFNPP staffs Sam le Collection Methodolo Ao Lake Water The two indicator s tations are the respective inlet canals at NMPNS and JAFNPP ~ These samples are 'composited using sampling equipment which discharges into large collection tanks. These tanks are emptied weekly and an aliquot is saved for the monthly composite.

The control station sample is collected from the City of Oswego water intake. Grab samples are drawn from the intake prior to treatment and are composited in a la ge sample containe ~

samples '

Quarterly composite samples are made up from aliquots of monthly

~

B~ Air Par ticulate/Iodine The air sampling stations a e located in two rings surrounding the site. The on-site locations ring the a ea around the plant inside the site boundary. The on-si te sampling ne twork is composed of nine stations The off-site air monitoring locations z ange six to seventeen miles fz om the site and are composed of six stations. Air monitoring locations are shown on Figuzes 1 and 3 ~

II'ESCRIPTION (Continued) 1~ Sam le Collection Methodolo (Continued)

BE Air Particulate/Iodine (Continued)

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 sample" ~ Directly down st earn from the particulate filter is a 2 x 1 inch charcoal cartridge used to absorb airborne radioiodine, The samplers run continuously and the charcoal cartridges and particulate filters are changed on a weekly basis, or as equired by dust loading.

The particulate filters are composited for gamma analyses on a monthly basis by location (two off-site, two on-site) after being counted for gross beta activity.

CD Milk Milk samples a e collected in polyethylene bottles f om the bulk storage tank at each sampled farm. Before the sample is drawn, the tank contents are agitated from th ee to five minutes to assure a homogenous mixture of milk and butterfat. Three gallons are collected during the first half of each month f om each of the locations within ten miles of the site and from a control location. The samples are frozen and shipped to the analytical contractor within thirty-six hours of collection in insulated shipping containers. The milk" samplihg locations are found'n Figure 5 ~ (see Table 19 for identification of locations sampled.)

D. Meat, Poultry and Eggs S emi-annually one kilog am of meat is collected from locations within a ten mile radius of the site. Weekly phone calls are made to the local butcher to determine availability of slaughtered live stock from within the sampling area. Whenever possible, meat samples are collected from locations previously used. (See Figure 4.)

Semi-annually one kilogram of poultry and one kilogram of eggs are collected from each of three locations within a ten mile radius of the site. Attempts are made to collect poultry and eggs at the same time as the meat samples The samples for poultry and eggs are frozen and shipped in insulated containers. Whenever possible, samples are obtained from previously sampled locations Control samples are also obtained for meat, eggs, and poultry.

(See Figure ' 4

II~ DESCRIPTION (Continued) 1~ Sam le Collection Methodolo (Continued)

E. Human Food Crops Human food crops are collected during the, late summer ha"vest if

~

season at locations previously sampled, available. One kilogram each, of two types of fruits and/or vegetables from each of the

'three locations within a ten mile radius of the site ar e collected. The types of fruits and vegetables sampled depends upon what is locally available at the time of collection. Attempts are made to collect. at least'ne broadleaf type vegetable from each location. The fruits and vegetables are chilled 'prior to shipping and shipped fresh in 'insulated containers. Control samples are also obtained (See Figure 4.)

F. Soil Samples Soil samples are requi ed to be collected eve y three years at the air monitoring locations and are analyzed fo" Sr-90 and GSA. Soil samples were collected in 1983. Thus, 9 on-site samples and 6 off-site samples were obtained. The C off-site location, located approximately 17 miles from the site, is the control location.

G. Fish Samples I Available f ish species are obtained f om collections du"ing the spring and fall. Samples are collected from two of four possible on-site sample transects and one off-site sample t"ansect (See Figure 1). Available species are selected under the following guidelines:

1. Samples of 0.5 to 1 kilogram of edible po" tions only f or a maximum of th ee species per location

2. When independent species are not available at all three sample locations, a species may be divided into two samples for each location This procedure may be accomplished provided that a sufficient sample size is available for the species in question at all three locationsi Selected fish samples. are frozen immediately af ter collection and processing and are segregated by species and location. Samples are shipped frozen within two weeks in insulated containers.

H. Shoreline Sediment One kilogram of shoreline sediment sample is collected at one on-site location and one of f-site location.. Sedimen t sample s are collected from shoreline locations that .are frequently washed by the surf. Samples are collected semi-annually, placed in plastic bags, sealed and shipped for analysis in insulated containers

II'ESCRIPTION (Continued) 1 Sam le Collection Methodolo (Continued)

I'ladophora from two on-site locations and one off-site location.

sample containers, labeled, frozen and shipped in insulated containers for off-site analysis.

J. TLD (direct radiation)

Thermoluminescent d,osimeters (TLD's) are used to measure direct radiation in the JAF/NMP-1 environment. TLD' are placed locations using four types of selection criteria. TLD's are classified as either on-sita; off-site, special interes t areas, or control locations. On-site TLD's are located within the sita property boundary and are arranged in an approximate ring a ound the generating facilities (Figure 3) ~ Off-site TLD's a e located outside of the site property boundary and are arranged a ing approximately 7-11 miles out from the site. Special interest TLD's are located at high population locations such as indust ial sites, schools, etc. Control TLD's are located outside of the 10 mile adius of the site. These TLD' are positioned to <the east, west, and south of the site up to 20 miles away TLDs used of CaSOg during the fi st th ee quarters of 1983 were composed chips (two chips per dosimeter) and were sealed in polyethylene packages to ensure dosimeter integrity. Two dosimete s (four chips) were placed at each location TLDs used during the fourth quarter of 1983 were composed of rectangular teflon wafers impregnated with 25>> CaSOl,: Dy Phosphor. These were also placed in polyethylene packages to ensure dosimete" integrity. TLD packages were placed in plastic holders or were affixed to supporting su faces by tape sealing. TLDs were collected, replaced and evaluated on a quarterly basis.

K. Special Samples Special samples of shoreline sediment were collected during March of 1983 to help in evaluating samples collected during the fall of 1982 and sampLes collected du"ing the spring and fall of 1983 'hese samples (March 1983) were collected at the normal indicator and control locations.

No other special samples were collected during 1983 for the Radiological Environmental Monitoring Program.

II~ DESCRIPTION {Continued) 2 ~ Analyses Performed The Radiological Environmental Monitoring Program (EU2P) samples were analyzed by; Radiation Management Corporation, Teledyne Isotopes, and by the Site Environmental Laboratory during 1983 following samples were analyzed by the site'. 'he Air particulate filter (weekly gross beta analysis)

Air particulate filter (monthly gamma spectral analysis)

Airborne radioiodine cartridge (weekly gamma spectral analysis)

Lake ~ater (monthly gamma spectral analysis)

The remainder of the sample analyses, as outlined in Table 1 and 2, were analyzed by Radiation Management Corporation (January-June) and by Teledyne Isotopes {July-December) ~

3. Chan es to the 1983 Sam le P o am A~ In January of 1983, Radiation Management Corporation (the site's analytical contractor) was purchased by Teledyne Isotopes of Westwood, New Je sey. The Radiation Management Corporation, facility continued to analyze environmental samples fo the site under contract from Teledyne Isotopes. S ta ting approximately July of 1983, all operations were transfe ed.'f om Radiation Management Corporation' facility to Teledyne Isotope' Westwood, New Jersey facility. Effective July all >

envi onmental radiological ~

samples were analyzed by either Teledyne Isotopes or the site Environmental Laboratory. The transition from the Radiation Management Corporation facility to the Teledyne Isotope facility proceeded well with minimal difficulties .

BE Milk sample location 14, located ESE from the site at 9.8 miles, was deleted from the milk sampling program in June of 1983.

Milk has been collected from this location for many years in the past.* However, several other mill sampling locations had been located, as a result of milch animal censuses conducted during 1982, that demonst ated greater radionuclide deposition potentials. Since location 14 had a low potential fo deposition,. as determined by D/Q values, this location was deleted.

Milk sample locations 50, 55 and 60 were added to the milk sampling program at the initiation of the milk sampling season (May) ~ These locations were added, as a result of the milch animal censuses conducted

,demonstrated average potentials during 1982 'hese locations for radionuclide deposition,. as determined by D/Q values'

II'ESCRIPTION (Continued) 3 ~ Changes to the 1983 Sam le Program (Continued)

Milk sampl~ location 60 was deleted after May of 1983 This location, as noted above, was added to the program in May. Upon review of all the new and old milk sample locations in May, the two locations with the lowest D/g values were deleted. These locations were location 60 and location 14 (noted above) ~

DE Radiological Fish Sample Data One of the three fish samples collected at the Nine Mile Point location for Sr-89 and Sr-90 analysis was los t in laboratory processing while per forming the s tr ontium procedure. Since the Environmental Technical Specifications equire one sample at this location and three were collected (two ext a), this is not a violation of the specifications III~ EVALUATION OF ENVIRONMENTAL DATA .

The results of .the 1983 Radiological Environmental Monitoring Program (REMP) must be put into perspective considering the natural processes of the environment and the past radiological data. Seve al factors must be realized in order .to effectively evaluate anti interpret the data.

XXI. EVALUATION OF ENVIRONMENTAL DATA (cont.)

There are three separate groups of radionuclides that were detected in the environment during 1983. A few of these adionuclides could possibly fall into two. of the three groups. The first of these groups is naturally occurring radionuclides. It must be realized that the environment contains a broad inventory of naturally occurring radioactive elements ~ Background radiation as a function of primordial

, f r adioac tive elements and cosmic radiation o s olar origin offer s a constant exposur e to the environment and man. These radionuclides, s uch as Th-232, Ra-226, Be-7 and especially K-40, account f or a majority of the annual per capita background dose.

A second group of radionuclides that were detected are a result of the detonation of thermonuclear devices in the earth's uppe" atmosphere.

The detonation frequency during the early 1950's produced a significant 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 "educed the inventory through the decay of short lived radionuclides, deposition, and the removal (by natu al processes) . of radionuclides from the food chain such as by the process of sedimentation. Since 1963, several atmosphe ic weapons tests have been conducted by the People's Republic of China. In each case, the usual radionuclides associated with nuclear detonations were detected seve"al months afterwards and then afte" a peak detection period, diminished to a point where most could not be detected. The last such weapons test was conducted in October of 1980 'he resulting fallout or deposition f om this test has influenced the background radiation in the vicinity of the site and was very evident in many of the sample medias analyzed during 1981. Calculations of the resulting doses to man from fallout related adionuclides in the environment show that the contribution f rom such nuclides in some cases (such as Sr-90 or Cs-137) is signif icant and second in intensity only to natu al background radiation. guantities of Nb-95, Zr-95, Ce-141, Ce-144, Ru-106, Ru-103, La-140, Cs-137, Mn-54 and Co-60 were typical in air particulate samples during 1981 and have a weapons test origin.

The third group of radionuclides detected in the environment during 1983 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 reactors thus making a distinction between the two sources difficult, if not impossible, under the circumstances. Radionuclides falling into this category (as applicable to the 1983 Nine Mile Point Environmental Program) include Cs-137i Cs-134> I-131> Mn-54, La-140, and Co<<60 'he dose to man as a esult of these radionuclides is small and significantly .less than the radiation exposure from naturally occurring sources of radiation and from fallout.

III. EVALUATION OF ENVIROMiENTAL DATA (conti )

Thus, a number of factors must be considered in the. course of radiological data evaluation and interpretation. The evaluation and interpretation is made at several levels including trend analysis, dose to man, etc. An attempt has been made not only to zeport the data collected during 1983, but also to assess the significance of the radionuclides detected in the environment as compared to natural radiation sources. It 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 significance. In regards to these very small quantities, it further noted that at such minute concentrations the, assessment of the will be significance of detected radionuclides is very 'ifficult.

concentrations in one sample that are two times the concentration of Therefore, another, for example, are not significant overall. Eioreover, concentrations at such low levels may show a particular zadionuclide in one sample and yet not in another.

The 1970 per capita dose rate (Eisenbud) was determined to be 209 mrem per year. This average dose includes such exposure sources as natural, occupational, weapons testing, consumer products, medic&, etc. The 1970 per capita dose rate due 'to natural sources was 130 mrem per year. Of this dose, approximately 20 mrem per year is zeceivea by the gonads and other soft tissues and an additional 15 mrem per year is .

received by the bone tissue for a 70 kg (U5 lb) man. These doses (ie.

20 mrem and 15 mrem) are the result of gust K-40 alone, a naturally occurring relatively high energy beta emitter (1.3 >kiev') ~ The 1970 per capita dose rate dueto the nuclear fuel cycle is 0.0028 mrem per year ~

Background gamma radiation around the Nine Nile Point Site, as a result of radionuclides in the atmosphere and the ground, accounts for approximately 60 mrem per year. This dose is a result of radionuclides of cosmic origin (as for example Be-7), of a primordial origin (as Ra-226, K-40, and Th-232) and to a much smaller extent of a man-made origin from weapons testing. A dose of 60 mrem per year, as a background dose, is significantly greater than any possible doses as a result of operations at the site.

'ables for the aquatic media sampled during the 1983 samplin~ program. Aquati c samples were collected at four possible indicator locations. ThE, locations (on-site transect designations) used for on-site sampling were NNPV (01), N>IPP (02), JAF (03), and RiPE (04) (see Figure 1).

Because of the unavailability of various sample media, on-site samples were colected from combinations of the above listed locations, when required. NMPW and NMPP were combined into location %IPP NHPE and JAF were combined into location JAF.

.Off-site samples were collected at the Oswego Harbor area or further to the west (or east) and .therefore served as control locations.

'he Point (NMPP-02) and, the James A. FitzPatrick (JAF-03) facilities. The control location was located gust east of the Oswego Harbor area.

Spring collections made in June showed detectable radionuclides that were a result of naturally occurring sources, weapons testing and possibly plant related operations k-40 anc Be-7 are naturally occurring and were noted in both the indicator locations and the control location. K-40 ranged in concentration from 3.52 pCi/g (wet) to 6 .07 pCi/h (wet) ~ Be-7 ranged from 0.52 pCi/g (wet) to 0.67 pCi/g (wet). The, concentrations detected for K-40 and Be-7 were approximately the same as concentrations noted during 1982 ' third naturally occurring radionuclide detected in the June samples was Th-228. This radionuclide was detected at the he% location only and was found at a concentration of 0.05 pCi/g (wet) ~

Cs-137 was detected at all three locations during the, June coll'ections. Concentrations at the indicator locations were slightly greater than the control locationi Cs-137 at the NMP location showed a concentration of 0,06 pCi/g (wet) and at the JAF location showed a concentration of 0.04 pCi/g (wet).

to be a result of past weapons testing based on 1983 data and historical data. Cs-137 was detected at the control location at 0.03 pCi/g(wet) which was'lightly less than the Cs-137 concentrations detected in the indicator samples.

III. EVALUATION OF ENVIRONMENTAL DATA (Continued)

(*

A portion of the Cs-137 detected at the indicator locations may be a result of ope ations of the site Cs-137 at the control sample location is a result of past weapons testing ~

Co-60 was detected at the NMP location during June at a concentration of 0.09 pCi/g (wet) and at the JAF location at a concentration of 0 ~ 08 pCi/g (wet) ~ Co-60 was not detected at the control location. Although Co-60 has been 'detected at the control location in the past, it has not been detected since Co-60 was detected at a concentration o f 1979 ~ During 1979 0 ~ 01 pC'i/g (wet) and was a result of weapons testing during years prior to 1979. Co 60 detected at the NMP and JAF locations dur ing June of 1983, however, was a esult of operations at the site.

A third fission product radionuclide detected, in addition to Cs-137 and Co-60, was Mn-54 Mn-54 was detected at the NMP and JAF locations at concentrations of 0.02 pCi/g (wet) and 0.01 pCi/g (wet) respectively. Mn-54 was not detected at the control location. The absence of Mn-54 at the control location and presence at the indicator locations is indicative o f operations at the site. Mn-54 has not been detected at the initiated.

No othe" adionuclides were detected in the June 1983 samples using gamma spect al analysis S amples collec ted during August also showed detected concentrations o f K-40 and Be-7 ~ K-40 was detected at all three sample locations and ranged in concentration from 2.08 pCi/g (wet) to 3.12 pCi/g (wet). Be-7 was detected at all three locations and ranged in concentration from 0.37 pCi/g (wet) to 0 '5 pCi/g (wet) ~ Historically, Be-7 has been noted as appearing in some samples and not in others because of the minute concentrations detected. Th-228 was detected only at the NMP location at the concentration of 0 '2 pCi/g (wet) ~

Cs-137 was detected only at the NMP and JAF locations at concentrations of 0 '4 pCi/g (wet) and 0.03 pCi/g (wet) respectively. The detected concent ations are very small and are above the lower limit of detection for the August control sample. As noted above for Co-60, it is difficult to assess the presence of Cs-137 at the NMP and JAF locations and not at the control location because of the minute quantities detected. Cs-137 in Cladophora samples has historically been attributed to past weapons testing, however, a portion of the Cs-137 detected in the August samples can be attributed to operations at the site.

ZIZ. EVALUATION OF ENVIRONMENTAL DATA (Continued).

Co-60 was detected at the NMP and JAF locations during August at concentrations of 0 ~ 09 pCi/g (wet) and 0 ~ 11 p(.i/g (wet) respectively. Co-60 was not detected at the control location As noted above, Co-60 has been detected at the control location in the past but not since 1979 ~ The 1979 detected concentration was a result of past weapons tes ting. Co-60 detected during August 1983, however, was a result of operations at the site.

Mn"54 was also detected at the NMP and JAF locations at concentrations of Oi02 pCi/g (wet) and 0.04 pCi/g (wet) respectively. Mn-54 was not detected at the co'ntrol sample location. Mn-54 at the NMP and JAF locations is indicative of ope ations at the site S amples collected during 1981 showed detectable concentrations of many weapons testing radionuclides ~ These included cerium, zirconium, niobium, ruthenium, and cesium The presence of the radionuclides was att ibuted to the 1980 Chinese nuclea weapons test. The half-life of these radionuclides ange from 33 days to 365 days with the exception of cesium (Cs-137 has a 30 year h alf-life) . During 1983, these weapons testing adionuclides we e not detected with the exception of Cs-137. This observation is consistent with obse vations in 1982 The absence of these radionuclides is attributed to nuclear decay and ecological cycling.

Review of past environmental data shows that the concentrations of naturally occurring K-40 and Be-7 have fluctuated greatly.

K-40 at all locations has anged from 2 ' pC1/g (wet) to 28.0 pCi/g (wet) ~ Be-7 at .all locations have anged from 0.05 pCi/g (wet) to F 00 pCi/g (wet) ~ Different years showed different peak concentrations for the two radionuclides. Cs-137 since 1979 at the indicator locations has been variable. The annual mean concent ation in 1979 (0.15 pCi/~-wet) was higher than 1980 (0 ~ 02 pCi/g-wet) . 1981 (0 ~ 36 pC i/guet) was gr eater than the preceding year. The annual mean for the indicator samples during .1982 was 0 ~ 015 pCi/g (wet) whMh represented a decrease when compared to 1981. During 1983> Cs-137 at the indicator locations averaged 0 ~ 04 pCi/g (wet) ~ This epresented an increase over the 1982 concentration Cs-137 at the control location has also been variable. The 1979-1981 annual means for Cs-137 were 0,03 pCi/g, 0.02 pCi/g, and 0 i 10 pCi/g (wet.)

r espectively. Fluctuations in the Cs-137 concent ations is a resul t of pas t weapons tes ting. An example of this is the October 1980 Chinese weapons test. The 1981 mean concentration increased at both indicator and control locations as a result of this testi The 1982 " annual mean was 0 ~ 007 pCi/@~et which represented a decrease. During 1983 Cs-137 was detected a t 0 ~ 03 pCi/g (wet) ~ This was an increase when compared to 1982 ~

III'VALUATIONOF ENVIRONMENTAL DATA (Continued)

Co-60 during 1979-1982 at the indicator locations averaged 0.16, 0.02, 0 ~ 55 and 0 ~ 02 pCi/g (wet) respectively. During 1983, Co-60 averaged 0.09 pCi/g (wet) which was a general decreas e when compared to 1979-1982 ~ Co-60 at the control location was detected only once during 1979 ~ During 1983, Co-60 was no t detected at the control location. Mn-54 during 1979-1982 at the indicator locations averaged, in pCi/g (wet) 0.12, 0.04> 0 14 and not detected, respectively. During 1983, Mn-54 averaged 0.02 pCi/g (wet) which was a decrease. Mn-54 at the control location during 1983 was not detected during 1979-1982, nor was it detected The significance of the detected radionuclides in Cladophora samples during 1983 is very small. This sample media has a high bioaccumulation factor for most radionuclides and the results of "the analyses can be used, for the most part, in a qualitative sense only. Thus, Cladophora does not reflect the grows. As an example, the bioaccumulation factor for Cs-137 is 80-4,000 for this sample media.

is not a human food source For the purpose of illustration, a comparison of hypothetical doses can be calculated on the basis In'this case, Cladophora is assumed to be consumed by an adult at an annual rate equal to green leafy vegetables, i.e. 64 kg/year (Regulatory Guide 1.109). A conse vative assumption can also be made that the mean Cs-137 concentration for 1983 at the indicator locations minus the mean control location concentration is a result of operations at the site Further, it is assumed result of ope that positive Co-60 and Mn-54 concentrations a e a ations at the site.

Maximum whole body and critical organ doses to an adult a e as follows:

The evaluation of past Co-60 data indicates that Co-60 has not been 'etected in the past at 'ither indicator or contzol locations since 1979 with the exception of one sample fron the indicator location in 1982 (0.16 pCi/g-d~) ~ Results from 1983 show that Co-60.was detected in both of the required indicator samples (0.14 and 0.36 pCi/g"dry). Co-60 has not been detected in any of the control samples from 1979-1983 ~ It appears that Co-60 concentrations at the indicator 'location are increasing (from not previously detected).

Evaluation of Sz-90 his torical data since 1979 shows that concentrations have generally decreased at the control location from a maximum of 0 ~ 04 pCi/g (dry) in 1979 to not detected in 1981 and 0.0043 pCi/g (dry) in 1982 ~ Sr-90 a t the indicator location has gene" ally r emained the same f om 1979-1981 but showed an increase in 1982 The increase, as noted above, is c onsis tent with past cont" ol sample data (1980) and may not necessarily demonst ate an increasing t end.

III. EVALUATION OF ENVIRONMENTAL DATA (Continued)

A 2. Dam Shoreline Sediment .Table 4 (conti)

The source of the elevated Co-60, Cs-134 and Cs-137 concent ations is believed to be liquid effluents from the site. Site liquid effluents during 1982 and 1983 were well within Technical Specification limits, although the quantities of Co-60, Cs-137, and Cs-134 did increase during the first three quarters of 1983. Other potential sources of radionuclides in liquid effluents are the sewage treatment facility effluent and the s torm sewer drainage which accep ts i ts most signif icant d ainage from building foundation sumps, roof drainage, and roadway drainage. Grab samples are obtained weekly from <he storm sewer drainage system and from the sewage treatment plant effluent which both discharge at points near the %P shoreline sediment sample location. Review of, weekly data showed no detectable concentrations of Co-60, Cs-137 or Cs-134 from the end of 1982 through 1983 ~

The presence of Co-60, Cs-137, and Cs-134 in other aquatic sample media shows no similar tends, as observed in sho eline sediment. Algae or Cladophora esults for 1983 gene ally showed lower concentrations of these radionuclides when detected. In additi'on, f ish sample results showed no detectable Co-60 nor Cs-134 Cs-137 was detected in indicator fish sample as well as control samples with no s ignifscant differences be tween the two. Zt appears, therefore, that the increased concentrations of Cs"3.37, Co-60 and Cs-134 a e. specific,to shoreline sediment and not other aquatic sample medias.

Shoreline sediment samples will continue to be collected and analyzed as required by the Environmental Technical Specifications. These samples may be supplemented with additional samples, if necessary, in an effort to fu ther assess any possible impacts.

The impact of the 1983 shoreline sediment sample results is minimal and can be evaluated by pro)ecting a dose to man using s tandard Regulatory Guide 1.109 methodology. The critical pathway, in this case, is direct radiation to the whole body ~

The presence of Co-60, Cs-134 and Cs-137 is a r esul t of operations at the site.

Analysis of the spring 1983 fish samples indicated detectable concentrations of radionuclides related to past weapons testing and natural origins (naturally occurring). Small detectable concentrations of Cs-137 were found in all fish samples (including control samples) ~ Sr-89 and Sr-90 were not detected in control or indicator samples. Spring fish collections were comprised of two separate species and nine individual two species represented one feeding type. Lake trout and samples'he brown trout are highly predacious and feed on significant quantities of smaller fish such as smelt, alewife, and other smaller predacious species. Because of the limited availability of species present in the catches, no bottom feeding species were collected in the spring samples.

Cs-137 was detected in all on-site and off-site samples collected during the spring for both species collected. On-site samples showed Cs-137 concentrations to be slightly greater than control levels for some samples and slightly less than 'control levels for other samples. The average indicator Gs-137 concentration was less than. the average control concentration.

The concentrations detected, however, are not significantly different from the control results and are therefore considered to be representative of background concentrations. Cs-137 in lake trout samples ranged from 0,033 tc 0.056 pCi/g (wet) for the indicator samples. Cs-137 in the control samples ranged from 0.049 to 0.057 pCi/g (wet) for lake trout. Cs-137 in brown trout samples ranged from 0.042 to 0 '46 pCi/g (wet) at the indicator locations. Cs-137 in the control sample was 0.046

'pCi/g (wet) (one sample collected).

Sr-89 and Sr-90 were not detected in the 1983 spring fish samples. Sr-89 and Sr-90 have routinely been detected in previous years.

KWO was detected in all of the spring samples collected. K&0 is a naturally occurring radionuclide and is not related to power plant operations. Detectable concentrations of KAO in the indicator samples (lake trout and brown trout) ranged from 2 ~ 9 to 3.8 pCi/g (wet) and 3 0 to 3.1 pCi/g (wet) f or the control samples No other radionuclides were detected in the spring fish samples.

Fall sample collections were comprised of two separate species and nine individual samples. Six samples of lake trout and three samples of brown trout were collected at a combination of two on>>site sample locations (NMP and JAF) and one off-site sample location (Oswego Harbor area) ~ Samples were collected by gill net in October.

Cs-137 was detected in all nine samples including the thre e control samples. Control . samples showed an average Cs-137 concentration that was greater than the indicator sample mean from the on-site locations. The detected concentrations were not significantly different from one another because of the extremely small quantities detected.

Review of pas t envi onmental data indicates that the Sr-89 concentrations have decreased steadily since 1976 f or both indicator and control locations. The indicator sample mean results have decreased, significantly since 1976 'hese results ange from an annual mean of 0.27 pCi/g (wet) in 1976 to 0 0035 pCi/g (wet) in 1982.

Control sample results have decreased as well, from 0.25 pCi/g (wet) in 1976 to 0,0063 pCi/g (wet) in 1982. Sr-90 was not detected in 1981, however, the LLD level and the 1982 detected level are approximately. equal. Sr-90, during 1983, was not detected in any of the samples collected at the indicator or control locations The general decline in detectable Sr-89 and Sr-90 results is most probably a esult of the incorporation of these radionuclides with organic and

~

inozganic substances through ecological cycling. In addition, Sr-89 has a relatively shozt half-life of 52 days.

The 1983 control sample mean was 0.049 pCi/g (wet) ~

As noted for Sr-89 and Sr-90 above, the general decreasing trend for Cs-137 is most probably a result of ecological cycling. A s ignificant portion of Cs-137 detected since 1976 in fish is a result of weapons testing fallout, and the general downward trend in concentrations will continue as a function of ecological cycling and nuclear decay.

Lake Ontario fish are considered an important food source by many. Therefore, fish is an integral part of the human food chain. Based on the importance of fish in the local diet, a reasonable conservative estimate of dose to man can be calculated. Assuming that the average adult consumes 6.9 kg of fish per year (Regulatory Guide 1.109) and the fish consumed contains an average 'Cs-137 concentration of 0.045 pCi/g (wet)

(annual mean result of indicator samples for 1983) the whole ~

body dose received would be 0 '22 mrem per year. The critical ~

organ in this case is the liver which would receive a calculated dose of 0.034 mrem per year. No doses are calculated here for Sr-89 and Sr-90 since these radioisotopes of strontium were not detected during 1983. The Cs-137 whole body and critical organ doses are conservative calculated doses associated with consuming fish from the Nine Mile Point area (indicator samples).

Conservative whole body and critical organ doses can be calculated for the consumption of fish from the control loc"tion as well. In this case the consumption rate is assumed to remain the same (6 9 kg per year) but the average annual Cs 137 concentration for. the control samples is 0.049 pCi/g (wet) ~ The calculated Cs-137 whole body dose is 0.024 mrem per year and the associated dose to the liver is 0.037 mrem per year. No doses for Sr-89 or Sr-90 are calculated here because, as noted above, these radioisotopes of strontium were not detected during 1983

The 1983 gross beta annual mean activity for the Nine Mile Point Unit 81 and the James A FitzPatrick inlet canal (2.8 pCi/liter) was approximately the same as the 1982 mean inlet canal result (2 ~ 7 pCi/liter), and was less than the annual mean results for the years prior to 1981. The Nine Mile Point Unit 41 canal samples were greater than the control samples for 7 of the 12 monthly samples analyzed and ranged from 0.6 pCi/liter to 7.9 pCi/liter. The James A.

The fluctuation in the gross beta canal sample results is due to the natural variation in the concentration of naturally occurring radionuclides A, slight increase in the gross beta activity was noted in the Nine Mile Point inlet canal samples for June. This result was 7'9 pCI/lite"~

A significant reduction in gross beta concentrations is notea when reviewing inlet canal gross beta results since 1974 ~ The reduction in gross beta activity is primarily the result of improved analytical procedures and equipment and not necessarily to changes in plant operationsi Although the past elevated gross beta concentrations may be due in part to past weapons testing, it is difficult to dete mine what portion was due to improved instrumentation and what part was due to weapons testing. There were no significant changes or trends in gross

~

beta activity on a monthly basis for 1983.

Gamma spectral analysis was performed on 36 monthly composite samples required by the Environmental Technical Specifications ~

Only one radionuclide was detected in the inlet canal and city water samples. This radionuclide was naturally occurring .

K-40 was detected intermittently in both intake canals and the aw city water supply. K-40 was detected in 3 of the 12 monthly inlet canal samples at Nine Mile Point Unit 1 and anged from 6.7 to 16.5 pCi/liter. The James A FitzPatrick inlet canal samples showed K-40 detected in 1 of the 12 monthly samples.

This concentration was noted in December and was 9.4 pCi/liter.

K"40 in the Oswego city water supply was detected only once, during June, at a concentration of 13.2 pCi/liter.

Quarterly samples for Sr-89 analysis we e composites of the monthly samples. Sr-89 was not detected in any of the quarterly canal samples or the raw city water samples during 1983.

Sr<<90 ranging from 0 ~6 pCi/liter to 1 0 pCi/liter and a mean value of 0 ' pCi/liter As demonstrated, the control location showed a mean result of 0.9 pCi/liter which is a result of natu al variation in the distribution of Sr 90. Sr 90, as detected in the 1983 water samples, is considered to be background Sr-90 as a esult 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. Tritium was detected in all samples taken at all three locations. The City of Oswego water t eatment plant showed tritium concentrations anging from 230 pCi/liter to 280 pCi/liter with a mean of 250 pCi/liter. Tritium concentrations for the James A, FitzPatrick inle t canal ranged from 249

~

pCi/liter to 560 pCi/liter and showed a mean concentration of 347 pCi/lite . Inlet canal samples taken at Nine Mile Point showed tritium concentrations ranging from 190 pCi/liter to 410 pCi/liter. The annual mean concent ation was 288 pCi/liter ~

Evaluation of past environmental data shows that gross beta

'concentrations in water samples have decreased significantly since 1977 at both the indicator sample locations (inlet canals) and at the cont ol location (Oswego City water) ~ As noted previously, however, the decrease is prima"ily a esult of more 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 pCi/liter in 1977 to 41 8 pCi/lite in 1976. For the period of 1978 through 1981, annual means ranged from 2 ~ 98 pCi/liter (1981) to 4 ~ 53 pCi/liter (1978). The indicator annual mean for 1983 was 2 8 pCi/liter Control sample annual means were also relatively high during 1975 to 1977 ~ Du"ing these years, the concentrations ranged from 45.33 pCi/liter (1975) to 10.9 pCi/liter (1977) ~ Data from 1974 for the control location was deleted from this comparison because of questionable results' or the period 1978 through 1981, annual mean gross beta concentrations ranged from 2.42 pCi/liter (1982) to 3.55 pCi/liter (1978) ~ The'ontrol annual mean for 1983 was 2.3 pCi/liter.

Mean results at the control sample location ranged from no t detected (1975 - 1978) to 1.10 pCi/liter (1980) ~

The annual mean Sr-90 results during 1983 for the indicator s amples and contr ol samples were <0.8 (LLD) pCi/liter and

<0.9 (LLD) pCi/liter, respectively.

Previous annual mean results for tritium at 'the indicator sample location has decreased slightly since 1976. Sample results were available since 1974 through 1982 and showed a peak value o f 4 620 pCi/liter (1982) and a minimum value of 194 pCi/liter (1982) . The annual mean tritium result at the indicator locations for 1983 was 317 pCi/liter. The indicated peak value of 4,620 pCi/liter during 1982 is a result of liquid waste discharges during reverse flow mode (of the inlet and discharge canals) and tempering gate maintenance. This occurrence was explained in detail in the 1982 Annual Environmental Operating Report, Part 8 The result is not an accurate indication. of tritium levels in lake water as demonstrated by the JAF inlet canal results Mean tritium results at the control location have decrease slighly since 1976, as was noted above for the indicator samples. Mean annual r esults were available for 1974 through 1982. These results showed that tritium at the control location ranged from not detected (1974) to 652 pCi/liter (1976). 1979 through 1982 mean results were consistent. The annual mean tritium concentration for 1983 at the control location was 250 pCi/liter.

The impact, as expressed by a dose to man, is not assessed here because the primary pathway in this case is drinking water. The nearest source for drinking water is the City of Oswego water treatment plant which is the control location for the sampling program. The results of the control location are consistent with previous years'esults and are representative of normal background radionuclide concentrations in lake water and regional drinking water. I

l. Air Particulate Gross Beta - Tables 9 and 10 Tables 9 and 10 contain the weekly air particulate gross beta results for the six off-site and nine on-site sample locations.

The samples were counted at a minimum of twenty-four hours afte collection to allow for the decay of naturally occurring radionuclides with short half-lives. A total of 312 off-site and 468 on-site samples were collected and analyzed during 1983 ~ No significant levels of gross beta activity wer e observed in any of the samples. The of f-site or control mean concentration fo" 1983 was 0.024 pCi/m while the indicator or on-site sample mean was equal to 0.023 pCi/m . As noted, the on-site annual mean is about four percent lower than the off-site mean foz'he same period. This difference in mean concentration has been exhibited in the past nine years with the exception of 1977 when a higher annual mean gross beta activity was observed for the on-site sampling stations. In these eight years, the control stations'nnual mean ranged from a minimum difference of 4.2 percent higher than the indicator s tations, observed in 1983; to a maximum difference o f 28 ~ 6 per cen t higher, observed in 1978. The diffe ence in off-site and on-site weekly and monthly mean values'for g oss beta could be the result of a combination of the many natural pzocesses which can affect environmental concentrations. The most significant parameter that could possibly contribute to a depressed or lowe concentration for the on-site stations would be location The close proximity of on-site sampling s tations to the lakeshore (Lake Ontario) would account for lower concent ations of naturally occurring radionulcides being collected on the sample filters. Surface winds from of f the lake would contain less particulate matter and airborne gases than surface winds from adjacent land areas The major component of gross beta concentrations are potassium-40 and decay or daughte" products of uranium and thorium. The concentrations of these nuclides in the ground level atmosphere are dependent upon the local geology and its chemical constituents. Thus, surface wind over land areas have a potential for containing highe" concentrations of naturally occurring radionuclides The observed small increases and decreases in general gross beta activity can be attributed to changes in the environment As discussed above, the concentration of the naturally occurring radionuclides in the lower limits of the atmosphe e directly

above land areas are affected by time related processes such as wind direction, snow cover, soil temperature and soil moistu e content. Little change was noted in gross beta activity which corresponded with weapons testing as has been observed in past years. Review of air particulate gross beta concentrations shows that no significant increases in concentration occurred du"ing 1983

'n general, the gross beta activity in air particulate samples has decieased significantly. The mean 1983 concentration for both off-site and on-site is 6.6 times lower than the mean concentration detected in 1981 and 1.3 times lower than 1982. This reduction in activity is directly attributable to the increased activity detected in 1981 as a result of fallout from an atmospheric nuclear test (i.e., the October 1980 Chinese Weapons Test) and subsequent "eturn to background levels jn 1983. The trend of gross beta

,activity in the environment is that of reduced concentrations. The mean 1983 concentration was the lowest level of gross beta activity observed since 1974, which is the extent of the review period ~

This general decrease is the result of the reduction of atmospheric nuclear testing in recent years in comparison to the 1960's when such testing was conducted on a more frequent basis.

Off-site composites include A-1 (off-site stations C, Dl and D2) and A2 (off-site stations E, F, and G) ~

The results for the composite samples analyzed during the 1983 sample program showed positive results for Ra-226, K-40, Be-7, Co-60, Cs-137, and La-140 ~ All six of these radionuclides, were detected in the on-site composites and five of the six wer e detected in the off-site composites (La-140 was not detected in off-site composite samples) ~

Ra-'226, K"40 and Be-7 are naturally occurring. Co-60, and Cs-137 are typically a result of weapons testing or operations at the site or a combination of both. La-140 is a result of operations at the site based on the relatively short half-life.

The total numbe" of radionuclides detected in 1983 was significantly less than 1981. This decrease was a result of the decay and deposition of weapons testing adionuclides.

The maximum on-site Co-60 concentration noted was 0 ~ 00173 which was 6 ~6 times the smalles t concentrati'on detected. The maximum concentration detected was noted in the Decembe 1983 composite sample. Co-60 was detected in 1 of the 24 off-site composite samples at a concentration of 0.00074 pCi/m (December 1983) ~

Co>>60 in the on-site and off-site composite samples is most probably a result of contamination during handling and possibly ope ations at the site The December samples, especially, are suspected to be a result-of contamination during the preparation process. After reviewing the December 1983 composite samples, a set of on-site and off-site particulate fQters were prepa"ed by the technician performing the environmental routine. These filters were then composited and counted at the envi onmental laboratory. The composited filters showed that Co-60 was present on unused filters. The concentration detected was 0.00307 pCi/m ~ The concentration was obtained by using a standard composite sample volume for the number of filte s composited and a standard count time. This concentation was. 1.8 times the concentration of the December maximum composite sample. The contamination was traced to the preparation process where the technician had prepared the individual filters on a table top covered with plastic Since the location was in proximity to a restricted area access, it is felt that small amounts of Co-60 were attracted to the plastic and subsequently transferred to the filters being prepared on the plastic The technician and subsequent replacement technician were instructed on how and where to prepare the particulate filters. Although conclusive proof cannot be provided that Co-60 in the December samples is a result of contamination during handling, the data indicates that a significant portion, detected was a result of contamination, if not all of the Co-60 Subsequent monthly composite samples starting during March 1984 will provide more information as to the source of Co-60

Historically, the naturally occurring radionuclides Ra-226, K-40 and Be-7 have shown flucuations that are represaxtative of natural changing conditions. -No significant trends were noted, as one would expect.

Co-60 has flucuated in the past primarily as a r esult of previous weapons testing. Co-60 average concentrations at the on-site and off-site locations from 1977. to 1978 decreased from approximately 0.0175 to 0.0015 pCi/m ~ Average concentrations decreased significantly during 1979 and increased in 1980 from approximately 0.0007 to 0.0016 pCi/m respectively. 1981 and 1982 average Co-60 concentrations decreased to 0.0007 and 0.0005 pCi/n . Avexage off si-te ano on-site concentrations were approximately equal ~ The 903 on-site average Co-60 conceatration was 0.0007 pCi/m $ or slightly greater than th e 1982 concentration. The 1983 average off"site mean Go-60 concentration was 0.0007 pCi/m which also was slightly greater than 1982 results. As noted previously, however, a portion of the Co-60 detected during 1983 was attributed to contamination during handling of the unused filters.

Historically, Cs-137 has been variable during the past. During 1977, both on-site and of f-site Cs-137 average con~entrations were approximately equal and averaged 0.0039 pCi/m . Cs-137 average concentrations at on-site and off-site locations decreased during 1978 and 1979 to 0 0017 and 0 0013 pCS/m r espectively. Average concentrations during 1980 and 1981 were approximately equal at off-site and on-site locatons and decreased slightly in 1980 and increased slightly in 1981 from 1979. The 1980 and 1981 average concentrations were 0.0012 and 0.0015 pCi/m respectively.

Cs-137 'decreased The yean 1982 concentration to 0.0004 pCi/m ~ The 1983 mean Cs-13 7 f or concentration for the on-site and off-site composite samples were 0.0002 and 0.0002 pCi/m which was a reduction from 1982 results.

La-140 has been detected intermittently during previous sampling years. La-140 was detected in 1978 (as Ba/La-140) at average concentrations of 0.0023 (on-site) and 0.0047 (off-site) pCi/aP . La-140 was not detected again until 1981 where found at a concentration of 0.0186 pCi/m it was (off-site) .and 0.0466 pCi/m (on-site) ~ No positive results for La-140 were noted during 1982. La-140 during 1983 was detected only once in an on-site composite at 0.00113 pCi/m, Based on the smal 1 amount of data available, La-140 has decreased significantly since 1981 and 1978.

I-131 was detected four times during 1983 in the on-site sampling stations. The concentrations ranged from 0 '22 to 0 '35 pCi/m and averaged 0 028 pCi/m ~ The detected concent ations were found during the weeks of 1/24/83> 5/30/83, 6/6/83, and 12/12/83.

A small portion of the concentrations detected was a result of operations of the site. The concentations detected during 1983 at the on-site sample stations were a result of operations at the site.

The I-131 concentrations detected in on-site samples during 1983 are presented below. The spacial distribution of the I-131 concentrations show that all four of the results were found at the H on-site environmental air monitoring station. This s tation is located 0.80 miles at 71'rom the NMP-2 reactor centerline (center, of the on-site environmental grid map) and is well within the- site bounda y.

The impact of I-131 concentrations at the H on-sit e environmental station can be assessed by projecting a maximum organ dose (thyroid) and whole body dose to the' itical individual. The projected doses are very conservative because the assumption is made that the critical individual is located at H on-site station, which is well within the site boundary and that the individual is at that location for a full week fo" each week that I-131 was deteted. The critical individual, in this case, would be a child Using standard Regula)ory Guide 1 109 methodology and an inhalation rate of 3700 m per year, the thy oid and whole body doses are calculated below .

As noted previously,- the projected doses are conservative since the critical individual (chil'd) is assumed to reside a t H on-site air monitoring station. Figure 3 shows the location of H on-site station and depicts this locaton as well within the site boundary. A more zealistic location, where members of the public would reside, would be outside of the site boundary at which point the I-131 concentration would be less A maximum exposure time of 168 hours0.00194 days 0.0467 hours 2.777778e-4 weeks 6.3924e-5 months per week is also conservative from the point of view of the residency time.

The calculated total dose f or the above mentioned critical individual would be 0.035 mrem to the thyroid and 0.000059 mrem t o the whole body assuminp a seven day sample period ana an inhalation rate of 3700 m per year (Regulatory Guide 1,109) ~

The resulting calculated whole body dose due to on-site I"131 concentzations is extremely small andi can be compared to a similar dose from natural or background radiation that an individual could receive as a result of changing elevation.

The associ'ated critical organ or thy oid dose fo" a child was shown to be 0.035 mrem for 1983 as a result of inhalation of 1-131. The adult thyrofd dose, uslnt the same criteria, ls 0.026 mram for 1983. These doses ara small and can ha put into perspective by comparing these doses to the dose to the thyroid as a result of inhalation of naturally occurring Be-7 in air ~

Be-7 is produced primarily in the upper atmosphere as a result of the interactions of cosmic rays from outer space with atmospheric argon, oxygen and nitrogen. The average Be-7 concentration detected duzing 198) was 0.1052 pCi/m ~

Assuming an inhalation rate of 8000 m pe" year for an adult, the 1983 annual thyroid dose would be 0 '88 mrem per year. The adult thyroid dose as a result of the inhalation of I-131 is only 5.3 percent of the dose as a esult of the inhalation of naturally occurring Be-7 near the Nine Mile Point site ~

The end result of the 1983 I-131 sampling effort showed no significant impact due to operations at the site. During 1983, I-131 was not detected in any other environmental sample media including milk and green leafy vegetables.

TLD results are'. organized into four groups for evaluation purposes ~ The groups are on-site TLD's (defined as TLD's in the immediate proximityof the individual facilities at .points of interest), environmental station TLD's (a ring c f TLD's surrounding the generating facilities as a group), off-site TLD's (TLD's located off the site property or controlled area at off-site environmental stations or points of interest), and control TLD's which are located beyond any influence of the site A net dose at the environmental station TLD' located on-site can be calculated simply by subtracting the mean s tanaard monthly off-site doses from the mean standard monthly on-site environmental station doses*. Environmental 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 net 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.

The difference could also result from statistical variation in the TLD readings, as the site boundary dose is based on a population of only eight individual readings per quarter.

On-site TLD results remained fairly consistent during 1983. The results for on-site TLD's were slightly above off-site background results except for TLD's located in close proximity to the generating facilities or radwaste facilities'LD's located near radwaste facilities, for the most part, showed variable results as a result of radwaste processing and shipments. TLD numbers 31 and 39 are located near the NMP-1 radwaste facilities and showed variable results. TLD numbers 27, 28, 29, 30, and 47 are located near the JAF radwaste facilities and also showed variable results as a result of radwaste processing and shipments. TLD's located near the generating facilities showed results slightly greater than off-site TLD results. These TLD's included numbes 23, 48, 61, and 4. TLD 83 is located near the Unit 2 construction site and construction pipefitting facilities. This TLD showed variable results that were up to two times normal background levels. This TLD was affected by the %P-1 and JAF generating facilities (when operable) and 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'LD's located in areas near radiography work will show fluctuating doses as the amount of radiography performed is not consistent. TLD 859 results were variable as a result of thE operating mode of the JAF facility. This TLD, is located near the JAF facility stack which primarily releases condenser air ejector gases ~

0 ff-site TLD results remained fairly consistent for mos t TLD locations each quarter. A slight increase in natural background radiation levels was noted for off-site TLD's in the first and second quarters of the year. This trenc, was also observed in the control TLD's. This is a result of increased emission rates for radon and thoron gases emanating from the ground. The emission rates are related to ground moisture content and other natural parameters TLD results for 1983 showed no detectable impact from direct radiation measured outside the site boundary.

B~ 5~ Radiation Monitors - Table 15 Environmental radiation monitors are located in 10 of the 15 air monitoring environmental stations. Each of the on-site environmental monitoring stations contains a radiation monitor and, in addition, the C off-site monitoring station contains a similar monitor. The radiation monitors consist of a GM detector with an associated power supply, chart recorder, and trip unit. The monitor has an operating 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 from the site. The monitors are not considered to be capable of high sensitivity environmental monitoring and do not detect minute fluctuation in levels of background radiation. Because of 'the relatively low sensitivity of the monitors (environmentally speaking) no comparisons are made between the radiation monitor readings and the readings from environmental TLD's.

K-40 is a naturally occurring radionuclide and is found in many of the environmental medias sampled.

Cs-137 was the only other radionuclide detected in the 1983 milk samples. Cs-137 was measured in 3 of the 66 monthly samples analyzed.

The annual Cs-137 values for each sampling location are variable but quantitatively the values are only slightly different from one another especially when the magnitude of these minute concentrations is considered. Location number 16 had an annual result slightly higher than the other locations ~ Location number 40 (control location) showed no detectable Cs-137 during 1983 or during 1982.

A significant portion of the Cs-137 detected in 1980 and 1981 was a esult of past weapons testing For these years, the detonation of a nuclear device in October 1980 by the Chinese contributed signif icantly to the measured Cs-137 concentr a-tions. During 1983, however, Cs-137 in milk is most probably a result of operations at the site. The impact, in any case, is extremely small During 1982 and 1981, pasture grass was collected and analyzed from the milk sample locations in order to help evaluate cesium in milk for those years. Pas ture grass samples were not collected during 1983 since a sufficient amount of data had been collected during 1981 and 1982 to evaluate any possible relationship.

No other radionuclides were detected in milk samples using gamma spectral analysis.

The gene al trend jn milk Sr-90 coricentations is a gradual reduction as a result of infrequent weapons tests'he impact as a result of Cs-137 in 1983 milk samples can be assessed by calculating conservative doses to man from the consumption of milk with detectable quantities of Cs-137 ~ For purposes of a calculated dose, the 1983 mean indicator

'he sample Cs-137 concentration is used (7.2 pCi/liter).

Assuming a consumption rate of 330 liters (87 18 gallons) p'er f

yea" or an infant (Regulatory Guide 1.109 maximum exposed individual), the whole body dose would be 0.026 mrem and the critical organ dose would be 0o363 mrem to the liver The calculated doses are based on 3 months of consumption (3 months of detectable Cs-137 sample results) ~ Since Cs-137 was not detected at the control location in 1983, a dose calculation cannot be performed. For a limited comparative purpose, the calculated dose to an infant as a result of consuming milk from the control location during 1981 would be 0 F 005 mrem whole body dose and 0.072 mrem critical organ dose (dose to the liver) ~

The annual mean Cs-137 concentration for the 1981 control location was 4 3 pCi/lite (Cs-137 was only detected in one of the eight monthly samples du"ing 1981) ~

The calculated dose to an adult can be determined assuming a consumption rate of 110 liters (29 ~ 06 gallons) pe year (Regulatory Guide 1.109) and a mean Cs-137 concentration of 7.2 pCi/liter for the indicator locations. The resultant doses are 0014 mr em to the whole body 'and 0022 mrem to the liver (critical organ) ~ The calculated doses are based on 3 months of consumption. As noted above, Cs-137 was no t detected a t the control location, therefore no whole body or critical organ dose can be calculated.

For the purpose of illustration, the significance of the above doses can be brought into perspective by comparison to backg"ound doses due to cosmic radiation with changes in altitude. Assuming the above calculatd whole body dose, as,a result of the consumption of milk, is 0.026 mrem to an infant and is totally a result of plant ope ations at the site, a comparison can be made to the incremental increase in dose due to cosmic radiation at sea level. A dose of 0.026 mrem whole body is equal to residing at a location 100 meters (328 feet) higher in altitude for 4~7 days.

An additional comparison can be made to naturally occurring K-40 ~ K&0 has been noted in almost all environmental samples at significant levelsi A 70 kg adult weights approximately 154 pounds and contains approximately O.l microcuries of K-40 as a if r esult o f normal 1 e functions ( inhalation, consumption, etc.) ~ The dose to the bone tissue is about 20 mrem per year as a result of the inte nal deposited K-40. For comparison purposes, an adult bone dose can be calculated that results from the consumption of milk from the 1983 indicator locations The mean Cs-137 concentration of 7 ~ 2 pCi/liter is used. The r esulting b'one dose is 0 ~ 016 mrem per year (an average milk Cs-137 concentration of 7.2 pCi/liter is applied over 3 months of the yea ) ~ This dose is 0.0008 of the bone dose as a esult of naturally occurring K-40 in a 154 pound adult.

The impact, if any, as a result of Sr-90 in milk, due to plant operation is extremely small since the mean esult of the indicator results and the control results are approximately equal considering fluctuations in the background levelsi The levels of Sr-90 detected in indicator as well as control samples are considered to be representative of background concentra-tions. In this regard, the resultant calculated doses would be approximately equal.

Iodine"131 was not detected in the monthly milk samples analyzed for the 1983 program. No doses to man have been calculated because of the lack of detectable I-131.

BE 7~ Milch Animal Census - Table 19 The milch animal census is an estimation of the number of cows and goats within a 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. Questionnaires not responded to are followed by telephone c'alls.

The. number of milch animals located within the ten mile radius of the site was estimated to be 1,213 cows and 0 goat's 'for the spring 1983 census. No new locations were found since the summer 1982 census. The number of cows increased by 72 and the number of goats decreased by 3 with espect to the 1982 summer census .

The 1983 summer census showed a total of 1,145 cows and 2 goats ~ This represents a decrease of 68 cows and an increase of 2 goats with r espect to the spring 1983 census. One milch animal location was added as a result of this census when compared to the spring 1983 census.

Collections for meat, poultry, and eggs were made in the s pring and fall seasons. Samples o f produce included vegetables and/or fruit with an at temp t t o sample at least one green leafy vegetable from each location.

The collection of produce was performed in late summer ~

Three indicator locations were sampled for each type of media collected, in addition, a control location was sampled during each collection period Indicator samples vere co11ected within a ten mile radius of the site in areas which would have a high potential for demonstrating possible effects of site operations. Control samples were obtained from areas greater than ten miles from the site, preferably in a least prevalent wind direction. The ultimate factor controlling sample locations was the .availability of required samples, Attempts were made to maintain prior sample locations were possible.

Spring meat collections were obtained at one control location (greater than ten miles from the site) and at three indicator locations (less than ten miles from the site) ~ Spring meat collections showed detectable concentrations of K-40 in all samples. K&0 concent ations ranged from 2.3 pCi/g (wet) to 2 '

pCi/g (wet) K-40 is a naturally occurring radionuclide. One of the four spring meat samples showed detectable concentration,s of Cs-137. The positive concentration was in one of the indicator samples. Cs-137 was detected at a concent ation of 0.023 pCi/g (wet). Cs-137 was not detected in the control sample.

Cs-137 was detected in many environmental samples and was most prevalent in. meat and. fish, with respect

~ to'll medias collected. Cs-137 in meat samples has typically been a the'ample result of pas t weapons testing. Cesium is incorporated into meat tissue from feed sources. The concentration detected in the spring meat sample was a very low concentration and thus could be detected 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 pCi/g [wet] and 0.024 pCi/g [wet]) ~ Cs<<137 was also found in the cont ol sample during 1980 (0 01 pCi/g [wet]) ~

No other radionuclides were detected in the spring meat samples using gamma spectral analysis Fall meat collections were made at one cont ol .and at three indicator sample locations The fall samples showed detectable concentrations of KAO in all samples. K-40 concentrations ranged from 2.4 pCi/g (wet) to 3.4 pCi/g (vet) ~ K-40 is naturally occurring.

Cs-137 was detected in three of, the four fall meat samples ~ The three positive results were all indicator samples (less than ten miles from the site) ~ The three results showed small c oncentrations of Cs-137 that were approximately a t the lower limit of detection (LLD) ~ The results were 0.044 pCi/g (wet),

0 ~ 014 pCi/g (wet) and 0 023pCi/g (wet) as compared to the control sample result of <0.006pCi/g (wet) ~ These results are very small concentrations and, as noted above or the spring f samples, are comparable to concent aeons detected at control location during 1981 with the exception of one sample The 1981 samples showed control Cs-137 concent ations of 0.017 and 0.024 pCi/g (wet) respectively. The impact of these small concentrations is discussed below No other radionuclides were detected in the fall meat samples using gamma spectral analysis The detection of Cs-137 in meat samples has been noted for all year s since 1978 for indicator samples and since 1980 for control samples (control samples were not collected prior to 1980) ~ 'rior to 1978, Cs-137 was not detected as a result of the limited sensitivity of the analyses. The detected concent ations'ince 1978 at the indicator locations have been fairly consistent. These samples ranged from 0.022'f to 0.038 pCi/g (wet) ~ At the control locations, Cs-137 ranged om 0'010 to 0 '20 pCi/g (wet) ~ The indicator sample annual mean results have been slightly higher than the control sample annual mean results.

The detection of Cs-137 in meat at control and indicator sample locations during 1978-1981 is an indication of cesium production from weapons testing. During 1982 and 1983, Cs-137 was not detected at the control sample location although Cs-137 has been detected in the past at control sample locations (1961, for example) ~ The detection of Cs-137 'n meat samples during 1983 is most probably a result of operations of the site although a small portion of this may be the a result of weapons testing.

In any event, the concentrations 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 annual Cs-137 concentration in meat during 1983 in the indication samples is 0.026 pCi/g (wet) A dose can be calculated to the critical organ and the whole body using standard Regulatory Guide 1.109 methodology. The critical organ is the liver of an adult.

liver dose as a result of consuming meat from within 10 miles of the site, as represented by the indicator sample zesults, would be 0.312 mrem per year. The whole body dose would be 0.204 mrem per year. A critical organ dose of 0 312 mrem per year is small and can be compared to the dose to the critical organ as a z esult o f consuming naturally occu ring KAO in foods and water The critical organs, in this case, are the gonads and other soft tissues which receive a dose of approximate 20 mrem pez'ear for a standard 155 pound man An additional dose comparison can be made considering bone tissue. The dose to the bone of an adult as a result of consuming meat with a Cs-137 c oncentration equal to the 1983 annual mean indicator sample concentration of 0.026 pCi/g (wet) is 0.228 mrem per year. A dose to the bone can also be calculated based on the 1983 annual mean K-40 concent ation of 2.8 pCi/g (wet). This dose, as adapted from NCRP Report 42, assumes the quality facto-" for the absorbed dose gamma doses.

The dose to the critical organ of an adult is small and as demonst ated above is minor compared to doses as a result of naturally occur ing K-40. The wnole body dose received from the consumption of meat with a Cs-137 concentration of 0.026 pCi/g (wet) was calculated above as 0.204 mzem per year. This dose can also be put into perspective by comparing this dose to the dose received from cosmic radiation with changes jn altitude. A whole body dose of 0,204 mrem is based on meat consumption for one year and is comparable to the increase in dose received when an individual moves to an altitude of 10.2 metezs (33 4 feet) higher for the same time period (i.e., one yea") ~

Egg samples were collected in the spring (May 1983) and in the fall (November 1983) ~ Samples were collected at three indicator locations (within ten miles of the site) and at one control location (greater than ten miles fzom the site) ~ The only radionuclide detected during 1983 in egg samples was K-40 was detected in the spring samples at concentrations that ranged

samples, the control samples had the lowest K-40 concentrations.

Poultry samples were taken during the spring (May .1983) and during the fall (November 1983) at three indicator locations and one contzol location. K-40 was detected in all spring and fall samples for both indicator and control results. ¹40 in the spring samples ranged from 1.7 pCi/g to 2.9 pCi/g (wet). The control sample had the lowe concent ation (1.7 pCi/guet) ~

samples during 1983. The concentration detected was very small and was approximately at the lower limit of detection (LLD) level for the other spring poultry samples. The detected Cs-137 concentration was 0.018 pCi/g (wet) ~ The LLD levels for the other samples ranged from <0.010 pCi/g (wet) to <0.018 pCi/g (wet) ~ Historically, the control samples for poultry have not demonstrated detectable concentrations of Cs-137 'lthough this sample is an indicator sample (i.e., within ten miles of the site), it is difficult to assess whether plant related or a minute background the cesium detected cesium concentration.

is In regards to background Cs-137> poultry can be compared to beef (meat) samples in the sense that Cs-137 resource)can become incorporated in tissue through the ingestion pathway. Thus, poultry have the potential to ingest Cs-137 through the pu"chased feed they consume (possible weapons testing but conversely they also have the potential to incorporate Cs-137 through ingestion of local deposition (plant related source) ~ In any event, the impact as assessed by a dose to man, is insignificant.

Cs-137 has been routinely observed in poultry samples from indicator locations in the past. Mean annual Cs-137 concent ations during 1978-1982 yielded concent ations of 0.012, 0 012, 0 '9, not detected and 0.03 pCi/g (wet) respectively. The 1983 concentration of 0.018 pCi/g (wet) is a 'reduction when compared to 1982 and is comparable to the average concentration for 1978-1982 's-137 has not been detected in control samples from 1978-1982, nor previous to 1978. Historical data indicates that Cs-137 in poultry samples collected during 1983 may be a result of operations at the site.

The'mpact, as a esult of consumption of poultry> can b e assessed by projecting a whole body and critical organ dose to an adult. A maximum, and therefore very conservative dose, can be calculated based on the one positive detection of Cs-137 a Cs-137 concentration of 0.018 pCi/g (wet), and a 'ssuming consumption ate of 110 kg per year (Regulatory Guide 1.109), a conservative dose to man can be calculated." The adult whole body dose is 0 ~ 071 mrem per year and the adult critical organ dose is 0108 mrem per year to the liver. These doses were calc'ulated for a six month period since Cs-137 was detected only during the first half of the year.

As noted in the assessment of the meat sample data, these doses are small when compared to an annual dose of 20 mrem,per yea- to the critical, organs, (the gonads and other soft tissues in this case) as a result of natu ally occurring K-40 in the environ-ment. The critical organ dose as a result of'onsumption of poultry containing 0.018 pCi/g (wet) of Cs-137 is 0.108 mrem for 1983 ~

This dose is 0.005 of the dose to .the critical organs as a r esult of naturally occurring K-40 in the environment. A comparison of the whole body dose calculated for poultry containing 0.018 pCi/g (wet) of Cs-137 and doses from natural conditions can also be performed The whole body dose was calculated, previously as 0 '71 mrem for 1983 increase in dose as a result of incremental increases in

Fruits and vegetables were obtained during the ha"vest season Collections were made during Septembe" at three i'ndicator locations and one control location. A successful attempt was accomplished to collect one broadleaf and one non-broadleaf fruit or vegetable at each location. Broadleaf vegetables of Swiss chard and cabbage and non-broadleaf fruits and vegetables of tomatoes, cucumbers, squash, and zucchini were collected.

K-40 was detected in all broadleaf and non-broadleaf vegetables and fruits. Broadleaf vegetables (Swiss chard and cabbage) showed concentrations of K-40 ranging from 1.8 pCi/g to 4.6 pCi/g (wet) ~ Non-broadleaf fruits and vegetables ( tomatoes, etc') showed concentrations of K-40 ranging from 1.2 pCi/g to 2.3 pCi/g (wet) ~ Be-7 was not detected'n any of the fruit and vegetable samples collected during 1983 'his occurring radionuclide had been detected during 1982 and natu ally intermittently prior to 1982.

No other radionuclides were detected in the 1983 collection of fruits and vegetables.

Review of past environmental data indicates that K-40 has been consistently detected in food crop samples. KAO concentrations have fluctuated from one sample to another but the annual ranges have remained relatively consistent from year to year. Be-7 has been detected occasionally during the past on leafy vegetables (1978 through 1982) ~

Dose estimates are not performed here for fruits and/or vegetables since no other radionuclides with the exception of naturally occurring K-40 were detected.

B~ 9. Soil - Table 21 Soil samples are collected every three years as required by the Environmental Technical Specifications, Soil samples were collected 'during 1983 at the nine. on-site air monitoring stations and at the six off-site air monitoring stations Samples were collected during 1977 and 1980 using this same criteria, Limited sampling for soil was also conducted during 1974 at select on-site locations.

III. EVALUATION OF ENVIRONMENTAL DATA (Continued)

B~ 9~ Soil Table 21 (cont.)

Soil sample results for 1983 included several radionuclides that are naturally occurring. These radionuclides included K-40, Ra-226, and Th-228. K-40 concentrations were highly variable as a result of the different soil types at different sample 1 ocations. K-40 c oncentrations during 1983 f or on-site and off-site locations ranged from 7.2-19.4 pCi/g (dry) ~ On-site and off-site concentration ranges were approximately equal.

KAO was detected at all sample locations. Ra-226 was detected in five of the nine on-site sample location's and three of the six off-site locations ~ Ra-226 anged from 1.13-2.15 pCi/g (dry) for on-site and off-site samples. On-site and off-site ranges were approximately equal Th-228 was detected in all on-site f and o f-site samples. Concentrations f or on-site and off-site samples anged from 0.52-0.94 pCi/g (dry) .

Cs-137 was detected in seven of the nine on-site samples and six of the six off-site samples. On-site samples ranged from 0.07-1 19 pCi/g (dry) and averaged 0 ~ 42 pCi/g (dry) ~ Off-site samples anged from 0.20-1.46 pC i/g (dry) and averaged 0.6 7 pCi/g (dry) ~ The off-site range and average concentration was higher than the on-site range and average concentration. The highest concentration detected for Cs-137 during 1983 was at the C off-site location which is considered a control location.

This variability of Cs-137 in the 1983 samples is a. result of the natural variation in distribution for this radionuclide ~

S everal ecological processes such as vegetation cover, terrain, erosion, etc. can affect the distribution of Cs-137 Cs-137 in soil samples is a result . of previous weapons testing. Any possible Cs-137 in on site samples as a result of operations at the site would not be able to be measured because of the natural variability of the concentrations The fact that the off-site mean is slightly greater than the on"site mean indicates that any possible Cs-137 concentration as a result of operations at the site is insignificant Historically, Cs-137 concentrations in on-site samples has decreased significantly since 1974, 1977 and 1980 ~ Mean Cs-137 concentrations for these years were 1.02> 1.03 and li26 pCi/g (dry) The 1983 on-site mean was 0.42 pCi/g (dry). '977 and

~

1980 off-site mean concent ations were also significantly greater than the 1983 of f-site sample mean concentration (off-site samples were not collected during 1974); Mean concentrations for the off-site locations during 1977 and 1980 were 1.17 and'.20 pCi/g (dry) respectively. The 1983 mean off-site Cs-137 concentration was 0 '7 pCi/g (dry) ~ The s'ignificant reductions in the on-site and off-site mean Cs-137 concentrations are probably a result of radiological decay of Cs-137, the reduced frequency of nuclear weapons testing, and redistribution of Cs-137 by vegetation'

B~ 9o Soil - Table 20 (cont~)

No other radionuclides were detected, in the 1983 soil samples using gamma spectral analysis Sz-90 was detected in seven of the nine on-site samples and six of the six off-site samples during 1983 off-site

. 'ean on-site and concentzations for Sr-90 were equal and showed a result of 0 e 18 pCi/g (dry) ~ On-site samples ranged 0.03-0~47 pCi/g (dry) and off-site samples ranged from 0.10&.32 pCi/g (dry).

Sr-90 in 1983 soil samples is a result of previous'eapons t es ting The 1983 sample results support this fact.

Variability in Sz-90 concentrations is a result of the natural variation in the distribution process, as was noted above for soil Cs-137 concentrations.

Historically, Sr-90 concentrations have been variable as a result of the distribution processes. The 1974 mean on-site concentration was 0 '7 pCi/g (dzy) ~ Subsequent years showed a general reduction in Sr-90 concentrations. During 1977, the on-site concentration was 0.40 pCi/g (dry) which was a slight increase compared to 1974 'he mean on-site concentration during 1980 showed a. significant decrease to 0.07 pCi/g (dry) ~

The 1983 on-site mean, as noted previously, was 0.18 pCi/g (dry) which represented a slight increase from 1980 ~ Off-site mean concent ations showed similar historical trends. Off-site zesults for 1974 were not available. Off-site results for 1977 and 1980 showed mean concent ations of 0.21 and 0.06 pCi/g

( dry) . The 1983 mean of f-site concentzation was 0. 18 pGi/g (dry) which was an increase in regards to 1980 ~

C Conclusion The Radiological Environmental Monitoring Program (~IP) was established to detect and evaluate any possible impact to the environment surrounding the Nine Mile Point area resulting f om operations at the site.

Samples epresenting higher trophic levels, such as fish and meat were reviewed closely to evaluate any impact to the general environment or to man. In addition, the data was reviewed for any possible historical tzophic level bioaccumulation trends. Little OD no impact could be determined resulting from radionuclide deposition considering all sources (natuzal, weapons testing, etc.) ~ In regards to doses as a esult of man-made radionuclides, a significant portion of the doses received by a member of the public was from past nuclear weapons testing. Doses as a result of natuzally occurring zadionuclides, such as K-40> contributed a.

major portion of the total annual dose to members of the public.

III. EVALUATION OF ENVIRONMENTAL DATA (Continued)

C ~ Conclusion (Cont.)

Any possible impact as a result of site 'operations is extremely minimal when compared,to the impact from natural background levels or weapons testing. It has been demonstrated that almost all environmental samples contain traces of radionuclides which are a r esult of weapons testing or natur ally occurring sources (primordial and/or cosmic related). Whole body doses to man as a result of natural sources (naturally occurring radionuclides in the soil and lower atmosphere) in Oswego County account for approximately 60 mrem per year as demonstrated by control environmental TLD's. Possible doses due to site operations is a small fraction of this particular natural exposure.

Therefore, as determined by review of the data presented herein, no impact due to operations at the Nine Mile Point Nuclear Station was detected that would effect the health and safety of the public.
