I. INEODUCTION

l-A INTRODUCTION The Power Authority of the State of New York (PASNY) is the owner and licensee of the James A. FitzPatrick Nuclear Power Plant (JAFNPP) which is located on the eastern portion of the Nine Mile Point promontory approximately one-half mile due east of the Niagara Mohawk Power Corpor-ation (HMPC) Nine Mile Point Nuclear Station (NMPNPS) . The NMPNPS unit

    #1 is located on the most western portion of the site and is a boiling water reactor wi th a design capacity of 610 MUe. The NMPNPS has been in commerical operation since the fall of 1969. Located between the JAFNPP and NHPNPS, Nine Mile Point unit #2 is under construct!on. NMPNPS unit
    #2 will have generation capacity of 1100 MWe and is expected to be completed in 1984. The JAFNPP is a boiling water reactor with a power output of 820 MWe (net). Initial fuel loading of fhe reactor core was completed in November of 1974.                              Initial criticality was achieved in late November, 1974.

The site is located on the southern shore of Lake Ontario in Oswego County, New York, approximately seven miles northeast of the city of Oswego, New York. Syracuse, New York is the largest metropolitan center in the area and is located forty miles to the south of the site. The area consists of partially wooded land and shoreline. The land adj acen t to the site is used mainly for recreational and residential purposes. For many miles to the west, east and south the county is characterized by rolling terrain rising gently up from the lake, com-posed mainly of glacial deposits. Approximately 34 percent of the land area in Oswego County is devoted to farming. The Radiological Environmental Monitoring Program for the Fitz-Patrick Plant is a site program with responsibility for the program shared by the Power Authority and Niagara Mohawk. identical Technical

;

Speci fications for radiological moni toring of the environment a*. lows for joint sampling and analysis. Data generated by the program is shared by the two facilities with review and publication of the data undertaken through each organization. This report is submitted in accordance with S.cction 5.6.1 of Appendix B, to DPR-59, Docket 50-333. Environmental reports of this nature have been compiled and submitted in semi-annual and annual reports since 1974. This report contains data from samples representing the period from January 1, 1978 to December 31, 1978.

l-B PROGRAM OBJECTIVES The objectives of the Radiological Environmental Monitoring Program are as follows:

1. To determine and evaluate the effects of plant operation on the environs and to verify the effectiveness of the controls on radioactive material sources.

2. To monitor and evaluate natural radiation leve!s in the environs of the JAFNPP site.

3 <> meet the requirements of applicable federal regulatory guides and limits.

4. To provide information by which the general public can evaluate the environmental aspects of nuclear power using data which is factua: and unbiased.

II, Paocani IMPLEMENTATI0fl AND DESIGN 8

ll PROGRAM IMPLEMENTATION AND DESIGN To achieve the objectives listed in Section I-B, sampling and analysis are performed as outlined in Tables 1 and 2 in Section IV. The sample collections for the radiological program are performed by two groups. Texas instruments incorporated, Ecological Services Branch (TIES) performs much of the environnental sampilng. TIES is presently performing the Nine Mile Point Aquatic Ecology Study at the _ site which is required by Section 4.1, Appendix B of DPR-59 The staff required by TIES to perform this study is used to perform the terrestrial sampling required for the site radiological monitoring program. In-plant and remaining terrestrial sampling is performed jointly by the JAFNPP and NMPNPS staf fs.

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

The two indicator stations are the respective inlet canals at JAFNPP and NMPNPS. These samples are composited using con- , tinuously running pumps which discharge into large holding tanks. The control station sample is collected from the city of Oswego water intake. The sample is drawn from the intake prior to treatment and is composited in a large sample bottle. Quarterly composi te samples are made up f rom proportional all-quotes of monthly samples. B. Air Particulate / lodine The air particulate glass fiber filters are approximately two inches in diameter and are placed in sample holders in the intake line of a vacuum sampler. Directly down stream from the particulate filter is a 2x1 inch charcoal cartridge used to absorb airborne radiolodine. The samplers run continuously and the charcoal cartr!dges and particulate filters are changed _ on a weekly basis. The particulate filters are composited on a monthly basis by location (off-site, on-site) af ter being counted for gross beta activity. The air sampling stations are located in two rings surrounding the site. The on .ite locations ring the terrestrial area around the plants inside the site boundary.

B. Air Particulate / lodine (Continued) The on-site sampling network is composed of 9 stations. The off :lte air monitoring locations range 6 to 17 miles from the site and is composed of 6 stations. Ai r moni toring locations are shown on Figures Vlli-1, Vill-IA and Vill-2. C. Milk Milk samples are collected in polyethylene bottles from the bulk storage tank at each sampled farm. Before the sample is drawn the tank contents are agi tated from 3 to 5 minutes to assure a homogenous mixture of milk and butterfat. Two gal-lons are collected during the first week of each month from each of the five farms. An additional one gallon is collected from each farm at mid-month to make up the second half of the monthly composite. The complete composite is made up from one gallon collected during the first week of the month and one gallon from the mid-month collection. The samples are frozen and shipped to the analytical contractor within 24 hours of collection in insulated shipping containers. The milk sampling locations are found on Figure Vill-4.

d. Meat, Poultry and Eggs Semi-annually one kilograrc of meat is collected from locations within a 10 mile radius of the site. Weekly phone calls are made to the local slaughter houses to determine availability of slaughte; d live stock from within the sampling area.

Whenever possible meat samples are collected from locations previously used. Semi-annually one kilogram of poultry and one kilogram of eggs are collected f rom each of three locations within a 10 mile radius of the site. Attempts are made to collect poultry and eggs at the same time as the meat samples. The poultry and eggs are frozen and shipped in insulated containers. Whenever possible samples are obtained from on ously sampled farms (see Figure Vill-3).

                                         . F. Human Food Crops

• Human food crops are collected during the late summer harvest season at locations previously sampled, if available. One kilogram each, of the two types of frui ts and/or vegetables f rom each of the three locations within a ten mile radius of the site are collected. The types of fruits and vegetables sampled depends on what is locally available at the time of collection. Attempts are made to collect at least one broad-leaf type vegetable from each location. The fruits and vege-tables are chilled prior to shipping and shipped fresh in insulated containers (see Figure Vill-3).

d G. Soil Samples Soil samples are required once every three years. No samples were collected during 1978. Soll samples will be collected again during the 1980 sample season. H. Fish Samples Available fish species are removed from the Nine Mile Point Aquatic Ecology Study monitoring collections during the spring and fall collection periods. Samples are collected from a combination of the four on-site sample transects and one off-site sample transect (see Figure Vlil-1). Available species are selected under the following guidelines:

1. 0 5 to 1 kilogram of edible portion only of a maximum of 5 species per location.

2. Samples composed of more than one 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 species per location are used. Weight of samples are the edible portions only.

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

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

J. Mollusks During the spring and fall seasons at two'on-site and one off-site location benthic samples are collected. The mollusks are collected by d' vers and sorted. The tissue is removed from the shell, frozen and shipped for analysis in insulated con-tainers. K. Bottom Sediments One kilogram of bottom sediment sample is collected at two on-site locations and one off-site location. Samples are collected at the same time and location as the mollusk sanples, where possible, by a diver. The samples are placed in plastic bags, sealed and shipped for analysis in insulated containers. _7_

L. Periphyton Peripyhton samples are collected in the spring and fall season from two on-site locations and one off-site location. Peri-phyton is collected from natural and/or artificial substrates (plexiglass slides). The periphyton is scraped from the substrates into vials, labeled, frozen and shipped in insu-lated containers for off-site analysis. M. TLD (direct radiation) Thermoluminescent dosimeters (TLDs) are used to measure direct radiation in the JAF/NMP-1 environment. The TLD stations are placed 'round the site using a three :one division. The first group of TLDs are located within the site boundary and are called "on-site" TLDs. The second set of TLDs are called "si te boundary" stations and are located at approximately the site perimeter. The third division of TLD stations are the "off-site" stations, located at the off-site air monitoring stations. Each TLD set is made up of 2 CaSO 4 dosimeters (2 chips per dosimeter), scaled in a polyethylene package to insure dosi-meter integrity. The TLD packages are further protected by placement in plexiglass " birdhouses", or bv tape sealing to supporting surfaces. The dosimeters are ct'lected, replaced and evaluated on a quarterly basis.

2. ANALYSIS PERFORMED The environmental radiological surveillance saaple analysis is performed by Radiation Management Corporation (RMC) except for the particulate =amples and iodine cartridges which are cou 'eu on site. These two sample media are counted on site to eilitate the compositing of the air particulate filters after gross beta analy-sis and the timely anclysis of charcoal cartridge for Iodine-131.

Other environmental radiological analyses are also performed by RMC. Tables 1 and 2 in section III list the media and the associ-ated analyses. ,

3. CHANGES IN Tile PROGRAM A. In April of 1978 the Analytical Contractor for the site environmental surveillance program was changed from the Eberline Instrument Corporation, Midwest Facility, West Chicago, Illinois (EIC) , to the Radiation Management Corpor-ation, Philadelphia, Pennsylvania.

B. A fifth milk sampling locar? was added to the 19'3 sampling program to serve as a cr k c! .ocasion. This farm, designated as location number 13 i, ' > - -eport is located approximately 22 miles south-southwt ok .c site. The sampling station is considered outside the iniluence of the plant.

C. Surface water samples for the first six nonths of the 1978 program were analyzed on site in the plant radiochemistry lab. Starting with July,1978, surface water samples were sent off site for analysis. RMC now p<rforms the analysis as listed in Table 1 Section III. The change in analytical labs resulted in an increase in sensitivity and climinated possible in-plant background interference. D. Air particulate composite sampics prior to July 1978 were analyzed on site in the plant radiochemistry laboratory. The July 1978 air particulate composite sample and subsequent samples were analyzed off site by P.MC. RMC now performs gamma spectral analysis of air particulate composites. As in item C above, the change in analytical laboratories resulted in an incre ', in sensitivity and eliminated possible in-plant background interference.

c. The milk sample station designated as location number 4 (see Figure VIII-4) is new for the 1978 sampling season. On2 of the farms used in previous sampling seasons declined to participate in the sampling program for 1978. This replacement sampling station was found prior to the beginning of the 1978 grazing season and is located approximately 7 miles east-southeast of the site.

III. SAMPLE SU5MARIES Environmental sample data is summari&cd by the following methods:

1. All sample data is summarized in table form. The tables are titled " Environmental Sample Statistical Analysis" and use the following format:

1. Sample medium

2. Type of analysis performed

3. Number of analyses performed

4. Range of detectable 1cvels. The data column is labeied " lower limits of detection". This wording is not intended to indicate that inclusive data is based on 4.66 sigma of background.

S. Mean value of the data, based on positive measured values. (1)

6. Standard Deviation, based on positive measured values.

(The standard deviations represent the variability of measured results for different samples rather than single sample uncertainty). (1)

7. Maximum and Minimum values

8. Range of the data, calculated by subtracting the minimum value from the maximum value.

2. Tables are provided for selected sample media and contain data summaries based on quarterly mean values. These tables are titled " Environmental Sample Summary."

(1) Only positive measured values are used in statistical calculations. The use of MDLs in these calculations would result in the means being biased high and the standard deviations being biased low.

V. RESULTS STATISTICS AND HISTOGRAMS S

V. RESULTS STATISTICS AND IIIST0 GRAMS The 1977 environmental sample data is presented in Section V in table format with associated histograms. A. Special Considerations

1) Only measured values were used in histogram and statistical calculations.

2) Ifistograms and associated data were generated only for sample medium or sample locations with sufficient data points for adequate graphic depiction (i.e. >5 data points).

B. Format

1) Basic statistics - the following statistics are reported with each histogram:

a) Number of data points used in developing the histogram, b) Mean or " average" of all data points used for each histogram. c) Standard Deviation of the data used for each histogram. d) Variance of the data used for each histogram. c) Minimum and Maximum values. f) Range of the data for each histogram. g) Class width used in generating the histogram

2) The llIST0GRANS presented in this section are a graphic display of frequency distribtuion, with equal intervals of values marksd on a horizontal axis. The frequency of each interval is indicated by a rectangular bar plotted on a vertical axis.

CELL STATISTICS for each histogram are shown by class number, lower bound, upper bound, frequency of occurrence and relative frequency in percent.

VI DATA

SUMMARY

AND CONCLUSIONS The results of the 1978 Radiological Environmental Monitoring Program must be put into perspective considering the natural processes of the environment and the aggregate of past data. Several factors must be considered in the course of radiological data evaluation and inter-pretation. First, it must be recognized that our environ includes an abundant inventory of natural background radiation of primordial and daily origin which is in a constant state of flux, influenced by a myriad of phenomena, from solar activity to barometric pressure. Secondly, the detonation of man-made nuclear devices in the atmosphere has resulted in an extensive array of radioactive isotopes in the atmosphere and on the surface of the Earth from global fallout. Section VII, titled HISTORICAL DATA, contains sample statistics from previous environmental sampling. In the process of determining the impact (or lack of impact) of the plant on the environment, the scrutiny of past analytical data can be a tool by which positive (and possible negative) trends cari be discerned. The interpreation of historical data in this report was done to a limited degree. Because of the constant change in analytical sensitivities, as state-of-the-art detection capa-bilities improve, data comparisons become difficult. Minimum detection capabilities for the 1969 and 1974 analyses of c,:vironmental data would be considered anomalies by 1979 analytical standards. A. LAKE PROGRAM Tables 3 through 9 list the analytical results for the aquatic media sampled during the 1978 sampling program. Aquatic samples were obtained at a coabination of four on-site locations. The transect designations used for the on-site sampling are NMPW (01), NMPP (02), JAF (03) and NMPE (04). Due to the local unavailability of certain required sample media, samples could not be obtained consistently at each of the same on-site transects sampled for cther media. Off-site samples were collected in the vicinity of the Oswego Harbor 0FF-SITE (00).

1. Periphyton - Table 3 The collection and analysis of periphyton organisms was per-formed twice during 1978. The first collection was on 6/27-28/78 and the second collection'was completed on 8/23/78. The results of gamma spectral analysis of these samples is pre-rented in Table 3, section IV. Analytical results show that a significant concentration of Cc-144 (pCi/g) was present in periphyton organisms collected on 6/27-28/78. The origin of Cc-144 in the periphyton samples is not totally certain, but the majority of evidence indicates that the concentration of Cc-144 in the sample is the result of atmospheric nuclear testing, fallout and the subsequent runoff into Lake Ontario.

The first piece of evidence that indicates that the presence of Cc-144 is not plant related is the fact that a concentra-tion of 0.10 + 0.06 pCi/g (vet) was present in the control station sample. The control station is located in the Oswego Harbor, 8 miles west of the site.

                                                       -121-

Based on the meterology and limnology of the area, the control station should not be impacted by plant operation. The liquid release of Ce-144 for the second half of 1977 and the first , half of 1978 was low with a total concentration of 2.89 x 10 ~ Ci. Calculation of expected concentrations of Ce-144 in aquatic plants can be made. Using a bioaccumation factor of 11 4000 pCi/kg per pCi/1 a discharge dilution o{01 82 x 10 liters, a release concentration of 2.90 x 10 pCi of Cc-144 and a near field dilution factor of 6, the maximum concentration of Ce-144 that can be expected to be found in periphyton organisms residing in close proximity to the plant is 0.106 _ pCi/g (wet). The calculated concentration of 0.106 pCi/g (wet) is a very conservative calculation and is well below the concentration present in the July 1978 sample. If a more realistic far-field dilution factor of 9 is used a maximum expected concentration of 0.071 pCi/g (wet) can be calculated which is 15 times less than the analytical results, indicating that the Cc-144 in the periphyton must be due to a source other than the plant effluent. The recond set of periphyton samples collected showed a reduc-tion in Cc-144 activity by a factor of 10 for the indicator or on-site sample stations using the maxima for each sample period. The concentration of Cc-144 at the off-site or control location showed a slight increase in activity from 0.10 pCi/g (wet) to 0.13 pCi/g (wet) . The presence of Cc-144 in both of the off-site sampics, further reinforces the belief that its presence is due to sources other than the plant. A concentration of 0.10 1 0.01 pCi/g (wet) of Co-60 was found in the August sample at the NMPP (02) transect. The signi-ficance of this level of activity may be only that it is 10 times the control station results. The total liquid release of Co-60 for the second half of 1977 and the first half of 1978 was equal to 0.235 Ci. An integrated release of this quantity should not produce any detectable environmental impact and was we'l within the discharge limits imposed by the plant's Technical Specifications. It should also be noted that the detection of a small quantity of Co-60 in the off-site or control station may indicate the presence of Co-60 is Lake Ontario periphyton. As stated above,any samples collected from the off-site location should be outside the influence of plant operation. A dose calculation from activity found in the lake periphyton is difficult as these organisms are not in the human food chain. For the purpose of illustration a dose calculation can be made using some unrealistic assumptions. If an adult were to consume 64 kg/yr of periphyton (an amount equal to the maximum annual adult consumption of Icafy vegetables), the dose from the on-site Cc-1]4 concentration would be 0.0018 mrem /yr (whole body) and would be 0.03 mrem / yr (whole body) from Co-60 with the total dose being equal to 0.0318 mrem /yr. The significance of this greatly over estimated dose is very low with respect to natural background radiation and the changes in the natural background 1cvels due to mans activities.

                                         -122-M                                          - - -

An examination of past periphyton data shows a decline in activity of Cc-144 and Co-60 in the periphyton organisms in the vicinity of Nine Mile Point. Past levels of Cc-144 and Co-60 are presented in graphic form in figures VIII-6 and VIII-7 respectively.

2. Botton Sediment - Table 4 Bottom sedt ant sampics were collected twice during the 1978 sampling effort. Gamma spectral analysis and Sr-90 analysis results are listed in table 4. The review of bottom sediment analysis results indicated that Cs-137 was the major nuclide occuring in this media. The presence of Co-60 was also de-tected in possibly significe t concentrations with a maximum concentration of 1.5 pCi/g (dry) at the JAF (03) sample loca-tion. The presence of Cs-137 in sediment samples may be attributed to a large extent, to the detonation of nuclear devices in the atmosphere. The long radioactive half life of Cs-137 (30 years) is condusive to the accumulation of this fission product in the environment. The presence of detect-able concentrations of Cs-137 at the off-site (00) sample station is strong evidence that the Cs-137 activity is from sources other than plant effluents.

The June 1978 sediment samples showed a Co-60 concentration of 1.50 + 0.20 pCi/g (dry) at the JAF (03) on-site sample location. The presence of Co-60 in sediment off shore from the plant may be due to deposition of plant effluents. The sediment found in areas of the plant is transient by nature often stirred up the regicn winde and waves, keeping sediment in the area from becoming heavily layered. The physical makeup of the aff-shore area is predominantly bedrock. The chemical properties of the sediment may cause Icw concentrations of trace metals to become concentrated by acting as an ion exchange medium with the dissolved material in the lake water. A second consideration that should be noted is that Co-60 concentrations in the vicinity of Nine Mile Point may be the results of atmospheric detonation of nuclear devices and the widespread global fallout and concentration of isotopes from surface runoff. The fact that higher concentrations were present at the on-site locations could be related to the non-existant or slow sedimentation rate of the promontory area while the control station located at the mouth of the Oswego River, would have a very high sedimentation rate, thus masking any radionuclide build up in buried sediment layers. The total liquid release to the lake for the third and fourth quarter in 1977 and the first and second quarters of 1978 was 0.270 Ci of Co-60 and 0.0134 Ci for Cs-137. All releases were well within effluent limits contained in the plant's technical specifications.

                                          -123-

The dose to man cannot be directly calculated for lake bottom sediment as bottom sediment is not accessible to man and any radioactivity found in the rediment is shicided by the over lying water. In addition, lake sediment is not direcity in the food chain of man or aquatic life. Bottom feeding biota may ingest small quantities of sediment but to a very limited degree. No passage of radionuclides to the human food chain from material deposited in lake sediment is expected. To display the impact of radioactivity in sediment samples with respect to the dose to man concept, the unlikely assumption could be made that lake bottom sediment could at some future time find its way to the surface and F:come shoreline sgdi-ment. Assuming that the density of sediment is 40 kg/m- (dry) and an average residence time on the shore of 47 hr/yr for a teenager, the annual dose from a Cs-137 concentration of 2.1 pCi/g (dry) would be 0.017 mrem /yr whole body and the dose from Co-60 with a concentration of 1.5 pCi/g (dry) would be 0.048 mrem /yr whole body, resulting in a total whole body dose of 0.065 mrem /yr. This dose could be considered minimal, if not insignificant with respect to natural background levels. A review of historical data shows the levels of Cs-137 to be randomly distributed with no definable trend evident. Past levels of Cs-137 and Co-60 are depicted in Figures VIII-8 and VIII-9.

3. Mollusks - Table 5 The results of Mollusk sampling are presented in table S.

Sampling efforts for mollusks in the vicinity of Nine Mile Point were of limited success during the first collection, in June, 1978. The lake bottom configuration off shore from the site is mainly bedrock, with sediment of insufficient depth to sustain a mollusk population. For this reason only NMPh' (02) and the off-site (00) location yielded sufficient quantities for a meaningful analysis in the June 27 ar.d 30, 1978 sample collection. Sufficient quantities were obtained at the off-site and 2 on-site transects in the October 2, 1978 collection. During both collections no mollusks were found on the JAF (03) t ransec t. Gamma spectral analysis revealed the presence of Mn-54 and Co-60 activity in mollusk tissue. Sh-54 activity was found in both co11cetions at the NMPP (02) sample transect. A possible explanation for the existence of such a disproportionate concentration of 55-54 could be the very high bioaccumation factor of manganese for fresh water mollusk of 90,000 pCi/kg per pCi/1. Such a high bioaccumulation factor would result in a rapid accumulation of manganese activity in mollusks which are indigenous to the off-shore area of the site. The total release of Co-60 and Sh-54 via liquid effluent from the plant for the period of July 1, 1977 to June 30, 1978 was 0.235 Ci for Co-60 and 0.199 Ci for 5b-54. Discharge di this same period of time was equal to 5.89 x 10}gition flow for liters.

                                                  -124-

The fresh water mollusks found in the vicinity of Nine Mile Point are not consumed by humans and are considered to be in the aquatic food chain to only a limited degree. Because fresh water mollusks are not considered edible, no accurate estimate of the possible dose contribution to man from their use as a food can be made. A dose estimate can be made using inflated parameters for the purpose of evaluation of possible dose contribution from the use of fresh water mollusks. Using the average individual consumption of seafood of 1.0 kg/yr for an adult the dose due to ingestion would be 0.001 mrem /yr whole body and 0.015 mrem /yr to the gastrointestinal tract from 56-54 concentrations. The dose resultirg from a Co-60 concentration of 0.22 pCi/g (wet) would be 0.001 mrem /yr whole body and 0.009 mrem /yr to the gastrointestinal tract. The maximum dose received from consuming 1 kg of fresh water mollusks in a year's time would be 0.002 mrem /yr whole body and 0.24 to the gastrointestinal tract. As illustrated above, the resulting dose is very low and in reality would probably be 0.00 because the species is inedible. The review of past data shows that Sr-89 and Sr-90 levels are declining but a limited number of data points does not provide evidence of a distinct trend. Graphs of previous mollusk samples with respect to 55-54 and Co-60 levels, are presented in figures VIII-10 and VIII-11,

4. Gammarus - Table 6 Gammarus samples were collected twice during 1978. The first sample collection yielded masses of 9, 12, and 38 grams at the NMPP (02), JAF (03), and off-site transects respectively. The August 1978 sampling effort yielded marginally sufficient sample volumes from JAF (03) transect with 248 grams and the off-site (00) transect with 478 grams. The NMPP (02) transect yicided only 64 grams of sample. Several attempts were made on each collection using a variety of sampling methods.

In spite of the low sample volumes, sensitivity of the gamma spectral analysis remained low. 50L values for Sr-89 analy-ses ranged from <0.07 to <0. '0 pCi/g (wet) . Insignificant 1cvels of Cs-137 and Ce-144 were detected in both the off-site sample and the on-site JAF (03) sample from the August 1978 collection. Both the Cs-137 and Cc-144 are suspected to be the result of atmospheric nulcear testing along with Sr-90 activity which was detected at all locations from the June and August collections.

                                -125-

An additional detectable measurement resulting from the analysis of gammarus samples was a 0.10 + 0.10 pCi/g (wet) concentration of Mn-54 found in the August NMPP (02) sample. The associated error for the analysis is on the order of 100'. resulting in littic analytical confidence in the results. Even if this lack of confidence was resolved the significance of the possible activity present is very small from a dose to man standpoint and an environmental impact viewpoint. The presence of trace amounts of Mn-54 in aquatic organisms can be related to the large bioaccumation factor of many fresh water o rgar.i sms . The analyses of gammarus show no significant impact from plant operation. IIistorical gammarus data shows reduction of Sr-90 levels in the organism. Cs-137 levels show a similar reduc-tion in the activity levels feua-1 in gammarus in the vicinity of the site.

5. Fish - Tabic 7 A total of 28 fish samples were collected from Lake Ontario and were analyzed for gamma emitters, Sr-89 and Sr-90 acti-vity. Sample collections were made during May (spring season) and October (fall season) at 2 on-site locations (NMPP-02, JAF-03) and one off-site location (OFF-SITE 00) .

Analysis results indicate no detectable impact from the operation of the plant. The data does show however a number of isotopes present in fish samples which can be directly attributed to atmospheric nuclear testing. Cs-137 levels were detected in 25 of the 28 samples collected for 1978, from both on-site and off-site sample locations. In addition, Sr-90 levels were detected in 20 of the 28 samples, again at both on-site and off-site locations. Because Lake Ontario fish are in the human food chain a reasonable estimate of dose to man can be made. Assuming that the average adult fish consumption is 6.9 kg/yr and the maximum activity level of 0.20 pCi/g (wet) for Cs-137 and 0.25 pCi/g (wet) for Sr-90 as found in the sampics are used, the calculated dose to man would be 0.33 mrem /yr whole body and 1.31 mrem /yr to the bone. If the amount of fish consumed were raised to the estimated maximum of 21 kg/yr, the resulting dose would be equal to 1.28 mrem /yr whole body and 4.31 mrem to the bone. The dose resulting from atmoshperic testing via fish samples can be calculated to be many times the dose calculated for previous sampled media, which may be considered to be related to the operation of the plant. 1.istorical data shows that the level of Cs-137 in the locally sampled fish has declined. Cs-137 activity reached a mean high of 1.40 pCi/g (h'et) in 1975 (at the indicator stations) and has fallen off.to the present mean low of 0.08 pCi/g (wet). Sr-89 and Sr-90 levels have shown a parallelism to the Cs-137 trend, with a mean high in 1976 of 0.27 pCi/g (wet), a present low of 0.01 pCi/g (wet) and 0.01 pCi/g (wet) for Sr-89 and Sr-90 respectively. Cs-137 levels have been graphed and may be found in figure VIII-12.

6. Lake Water - Tables 8A, 8B, 9 Lake Water samples are analyzed for gross beta, tritium, strontium 89, strontuim 90, and gamma emitters.

Gross beta, tritium and strontuim 89 and 90 analyses showed no evidence of plant related radiological impact on the environ-ment. The gross beta mean activity for 1978 was significantly lower than all previous years that analyses of lake water has been performed. This reduction in activity is most directly attributed to the improvement of analytical procedures and equipment. Lake water tritium has an indicator mean activity of 389 pCi/1 for 1978. Tritium levels in the area of Nine Mile Point have remained constant since sampled for H-3 (1974-1978). Tritium is a naturally occuring radioactive isotope of hydrogen which is produced in the upper atmosphere by cosmic radiation. The fact that Tritium is naturally occurrin may account for background levels in the lake varying slightly from year to year. Strontium-90 activity was detected in 9 of the 12 quarterly sampics. Both the on-site and off-site sample locations showed detectable levels of Sr-90, ranging from 1.10 pCi/1 to 0.40 pCi/1. As in the fish samples above, Sr-90 levels can be attributed to atmospheric nuclear testing. Overall Sr-90 levels have decreased slightly, fror 1977 to 1978. Strontium-89 was detected in 3 on-site samples during the year. All detectable Sr-89 activities were at or below the MDL level with associated errors ranging from 50 to 85 percent. The presence of these levels of Sr-89 is not considered to be significant and may be attributed to reccat atmospheric testing by the People's Republic of China. Analysis was performed on 36 monthly composites from 3 sample locations. Fluctuating backgrounds in plant counting equip-ment often resulted in background concentrations larger than the gross sample concentrations. The net sample concentrations were reported as 0.00+ accumulative error- (background error + sample error) . A number of posi.tive activities were detected for Co-60 and Mn-54. however, the larte error associated with the determination could Icad to the conclusion that no acti-vity was present in the sample and was the result of in-plant background. Because of the large associated analyses error and fluctuating counting room background, all samples after June 1978 were sent to a contractor for analysis so that lower background variations, and therefore lower statistical counting errors, would result. As indicated in table 9 (section IV) all analy-ses after June 1978 resulted in no positive detectable IcVels of activity, as would be expected, all analytical results were reported at MDL 1cvels.

• Concentration in pCi/1 B. LAND PROGRAM The results of terrestrial sample analyses for the 1978 reporting period are incluc ed in Tables 10 through 20.

1. Air Particulates - Tables 10 and 11 Tables 10 and 11 give the air particulate gross beta results for the 6 off-site and 9 on-site stations respectively. No significant levels of gross beta activity were present on the 315 off-site samples or the 466 on-site samples analyzed during the 1978 program. The off-site air monitoring stations showed a gross beta activity slightly greater than the associ-ated on-site stations for the same sample period (off-site mean of 0.14 pCi/m 3

                                             , on-site mean of 0.10 pCi/m3 ). Both the off-site and on-site gross beta activity are up slightly from the four previous years, but are significantly lower than the activity levels for 1969. This change in gross beta activity over the years can be attributed to several factors.                         In the early 1960's, atmospheric detonation of nuclear devices was proliferous. With the adoption of nuclear test ban treaties by most 6f the world's countries, the atmosphere had purged itself of most of the contaminates from this testing. The decrease in gross beta activity since the 1960's has been a world wide, and nationally observed trend.                         In the last several years, the majority of activity found on air parti-culate filters, analyzed for gross activity, is the result of naturally occurring activity in the form of uranium and thorium daughter products. The concentration of the naturally occurring isotopes in the biosphere is based on location and is affected by time related processes such as wind direction and snow cover. The fluxuation of natural background concen-trations and the fact that the People's Republic of China conducted two nuclear atmospheric detonations during 1978 can be considered the major reason for the slight increase in gross beta activity in the 1978 samples at both the off-site and on-site sample locations. Figure VIII-15 is a graph of air particulato gross beta activity from 1974 through 197S.
                                                   -128-

2. Monthly Particulate Composites - Table 13 On a monthly schedule, air particulate filters are composited by location (off-site /on-site).

Positive activities were detected at both the off-site and on-site sample of the following isotopes: Co-60, 55-54, Co-58, Nb-95, Zr-95, Cs-137, Cc-144, Ba La-140 and I-131. The presence ,f activity in air particulate samples prior to July 1978 are likely the result of in-plant background fluxuations affecti g sample counting equipment. The March sample analysis shows tne presence of I-131 in both the off-site and on-site composites. The concentrations were 2.50 x 10-3 pCi/m 3 for the on-site and 4.60 x 10-3 pCi/m 3 for the off-site sample. The MDL's for I-131 on composite samples ranged from 9.28 x 10-5 to 2.51 x 10-4 pCi/m3 . These I-131 activities can be directly attributed to a nuclear atmospheric test conducted by the People's Republic of China, on March 14, 1978. Using the off-site concentrations on a nuclide basis as control, the Febuary Co-60 activity of 1.53 x 10-2 pCi/m 3 in the on-site composite may be considered of possible significance, using two times the control station value as a screening level. As discussed above, this activity is likely a result of a counting environment background from the plant. Two nuclides were identified in the December composite but were not included in the second half of Table 12. The nuclides were Cc-144 and Ru-103 with concentrations of 2.8 + 1.9 x 10-4 - and 4.5 + 2.4 x 104 pCi/m3 respectively.

3. Airborn I-131 - Tables 13 and 14.

The results of the I-131 (charcoal cartridge) analysis for the six off-site and nine on-site monitoring stations are presented in Tables 13 and 14. The March 27-28 sample results showed detectable I-131 con-centrations at 4 of the 6 off-site sample locations and 5 of the 9 on-site sample locations. The off-site activity ranged from 0.03 + 0.01 to 0.04 + 0.01 p'Ci/m3 , while the corresponding on-site sample results rar.ged f rom 0.03 + 0.01 to 0 06 + 0.01 pCi/m3 . The source of the I-131 can be attributed to an atmospheric nuclear test conduct >d by the People's Republic of China, on March 14, 1978. The widespread occurance of detectable I-131, also evident in the monthly air particulate composite results, support the fact that the concentrations of 1-131 were due to the test conducted by the Chinese, and not plant operation. 9 4

During 1978, three single on-site samples showed detectable IcVels of I-131 activity. The 9/25 sample from the I on-site station showed an I-231 concentration of 0.02 + 0.01 pCi/M .3 The 6/27 sample at the H on-site station showed a detectable concentration of 0.07 + 0.01 pCi/m3 and the G on-site station 3 showed an activity of 0.04 + 0.01 pCi/m on 10/16. The activity reported in these samples is very low in concentra-tion and in each case close to the MDL level of 0.01 to 0.08 pCi/m3 (range). These measurements were recorded in the second half of the year and are not considered to be related to atmospheric fallout. Plant releases during the second half of 1978 were higher than the first and second quarter of 1978. The higher release rates for the second half of 1978 may be correlated to refueling outage maintenance. The concentrations detected during the second half of 1978 were analogous to the levels detected from atmospheric testing recorded earlier in the year. A dose calculated using the maximum detected coacentration of 0.07 pCi/m3 , and based on NRC staff assumptions in Rcgulatory Guide 1.109, would be equal to 0.83 mrem /yr to the thyroid and 0.001 mrem /yr to the whole body. This annual dose calculation is made using an inhalation rate of 8000 m 3/yr for the average adult and a dose factor of 1.49 x 10-3 mrem /pCi inhaled and 2.56 x 10-6 mrem /pCi inhaled for the thyroid and whole body dose respectively. The dose resulting frem the detected I-131 levels calculated above assumes that the level of I-131 con-centration in air remains constant for an entire year. A review of the data table shows that no I-131 concentration was detected for longer than one sample period which would be a maximum time period of 7 days. If the dose calculation is adjusted to reflect the real temporal distribution of the sample results, the dose calculation can be reduced by a factor of 52. The recalculated doses would then be 0.016 mrem /yr to the thyroid and 0.00003 mrem /yr (300 x 10-5 mrem /yr) whole body dose. Although trace amounts of I-131 were detected in 3 samples during 1978, this represents only six tenths of one percent (0.6 %) of the on-site samples collected during the year and only four tenths of one percent (0.4 %) of the total airborne iodine samples collected. It should be noted that minute traces of I-131 have and can be detected by our air monitoring system. A review of the data indicates that radioiodine releases are not routinely detected in the environs of the site as confirmed by the few actual detectable I-131 concentrations recorded during the 1978 operating period.

                                                                    -130-

4. TLD'S (Environmental Dosimetery) - Table 15 TLD results for the first and second quarters are reported as an average of 5 individual LiF chips. The third and fourth quarter TLD's are Ca(SO4 ) (Tm). Each reported value is the average of 4 independent readings (2 readings /TLD - 2 TLD's/

location). This is due to a contractor change starting in April of 1978. The TLD's are broken down into 3 groups for reporting purposes. The groups are on-sites, off-sites, and si - boundary (see sampic summary). The net dose at the site boundary (site boundary average - off-site average) for each quarter were 1, 1, 0, 0, respectively (mrem). The total site boundary dose (mrem) for 1978 was 2. Badges 31, 32, 39, and 40 are located within the NMP-1 fenced area near the Radwaste Building and are being influenced by waste trucks being loaded in the building or parked nearby. Badges 27 through 30 are located within the JAF restricted area and are being affected by waste trucks being loaded in or parked near the JAF Radwaste Building.

5. Radiation Monitors - Table 16 Radiation monitors are located in 10 of the 15 air monitoring stations. Each of the on-site air monitoring stations contains a radiation monitor and the C off-site station contains a similar radiation 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 of 0.01 to 100 mrem /hr. Each radiation monitor has a small radioactive source mounted on the detector to produce an on-scale reading. The design intent of the monitors is to detect possible dose rates resulting from plume releases from the plant. The radiation monitors are not considered capab :

of detecting minute fluxuations in levels of background radiation. Therefore, no comparison can be made between the radiation monitor reading with those of environmental TLD's. ,

6. Milk - Table 17 and 18 Milk samples were collected monthly from each of 5 farms and analy:cd for I-131. Twice per month milk was collected from the same 5 farms. The two monthly samples were composited by location and were analyzed for gamma emitters and Sr-90.

Tables 17 and 18 shows milk sample results for I-131, gamma emitters, and Sr-90 respectively.

                                            -131-

As noted earlier there were two Chinese nuclear tests con-ducted in the atmosphere in 1978. The first test was in mid-March and the second in mid-December. Milk samples were not collected during the period that fallout occurred in the Northeastern United States because cattle were not on open pasture due to snow cover. By the time cattle were on spring pasture feeding any expected I-131 fallout had decayed. Cs-137, a significant nuclear test byproduct would remain abun-dant and detectable for a much longer period of time. Due to the long half life of Cs-137 (30.2 years), the concentration has a tendancy to build up in the environment and thus was detected in every milk sampic (including the control samples) collected during 1978. The concentrations of Cs-137 varied during the 1978 grazing season due primarily to local weather patterns and precipitation trends. Cs-137 levels have shown a decreasing trend since 1976 in the vicinity of the site. Graphic levels of Cs-137 are shown on Figure VIII-16. Iodine IcVels in the 1978 milk samples were at or below the MDL level. One positive radiciodine concentration was de-tected during the year with a positive value of 0.19 + 0.07 pCi/1. This concentration is below the normal FDL 1cvel and - was due to long counting time, resulting in very high sensi-tivity. The dose estimate of a teen drinking 200 liters of milk per year, based on 0.19 pCi/1 of I-131 would be 0.05 mrem /yr based on a six month grazing season. The comparison of 1978 milk I-131 data shows a significant decrease in I-131 levels in milk _ from previous years sampled. It should be noted that previous data is biased by I-131 resulting from the detonation of nuclear devices in the atmosphere, while such results are not part of the 1977 and 1978 data. (See Figure VIII-17) . Sr-90 1cycls detected in 1978 milk samples are a remnant of past atmospheric testing. Detected levels of Sr-90 range from 2.5 pCi/1 to 10.0 pCi/1 and were recorded in both off-site and on-site samples. Past data review (1974-1978) shows a consis-tant level of Sr-90 in the milk samples since 1974. A peak concentration was recorded in the 1976 samples and levels have been on a general decrease to date. Figure VIII-18 represents a graph of Sr-90 levels from 1974 through 1978.

7. Milch Animal Census - Table 19 and Figure 5 The number of milch animals located within a ten mile radius of the plant is estimated to be 712 cows and 18 goats for the spring census; which shows a decrease of 223 cows and an increase of 15 goats from the 1977 spring census. The 1978 summer census showed a total of 643 cows and 17 goats which represents a decrease in the number of cows by 259 animals and an increase in the number of goats by 15 over the 1977 summer census.

8. Iluman Food Products - Table 20 The result of analyses performed on meat, poultry, eggs and food crops are shown on Table 20. Iluman food crop analyses for I-131 resulted in minimum detectable activities ranging from <3 to <10 pCi/kg (wet). All analyses were performed within one half-life.

Sight traces of Cs-137 were found in the meat, poulty, and egg samples as was to be expected. One positive detection of a trace amount of Mn-54 in a pear sample was recorded, which was suspect, due to the high associated counting error. The location was resampled and resulted in no detectable Mn-54.

                                                                                   '\

C. CONCLUSIONS The Radiological Environmental Monitoring Program is conducted each year to determine the radiological impact of the James A. Fit:- Patrick Nuclear Power Plant on the local environment. As demon-strated by the analytical results of the 1978 program, the major radiological impact on the environment was the result of fallout from atmospheric nuclear testing. The 1cvels of natural background and the associated fluxuation 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. It is therefore concluded that no appreciable radiological environ-mental impact has resulted from the operation of the James A. Fit: Patrick Nuclear Power Plant.
