NINE MILE POINT UNIT I ANNUAL ENVIRONMENTAL OPERATING REPORT INTRODUCTION This report is submitted in accordance with Section B to DPR-63, Docket 50-220.

DESCRIPTION The required sample collection and analysis schedule for NMP-1 is listed in Tables 1 and 2.

The sample collections for the radiological program are performed by two groups. Texas Instruments Incorporated, Ecological Services Branch (TIES) performs much of the environmental sampling. TIES is presently performing the Nine Mile Point Aquatic Ecology Study at the site. The staff required by TIES to perform this study is used to perform the terrestrial sampling required for the site radiological monitorin'g program. In-plant and remaining terrestrial sampling is performed jointly by the JAFNPP and NMPNS staffs.

1. SAMPLE COLLECTION METHODOLOGY A. Lake Water The two indicator stations are the respective inlet canals at JAFNPP and NMPNS. These samples are com-posited using continuously running pumps which dis-charge 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 large sample bottle.

Quarterly composite samples are made up from aliquots of monthly samples.

B. Air Particulate/Iodine 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 2 x 1 charcoal cartridge used to absorb airborne radioiodine. The samplers run continuously and the charcoal cartridges and particulate filters are changed on a weekly basis.

The particulate filters are composited on a monthly .

basis by location (off-site, on-site) after being counted for gross beta activity.

DESCRIPTION (Continued)

1. SAMPLE COLLECTION METHODOLOGY (Continued)

B. Air Particulate/Iodine (Continued)

The air sampling stations are located in two rings surrounding the site. The on-site locations ring the terrestrial area around the plants inside the site boundary.

The on-site sampling network is composed of 9 stations. The off-site air monitoring locations range 6 to 17 miles from the site and is composed of 6 stations. Air monitoring locations are shown on Figures 1 and 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 agitated from 3 to 5 minutes to assure a homogenous mixture of milk and butterfat. Three gallons are collected during the first week of each month from each of the five farms. The samples are frozen and shipped to the analytical contractor within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> of collection in insulated shipping containers. The milk sampling locations are found on Figure 4. (See Table 1S for identification of locations sampled.)

D. Meat, Poultry and Eggs Semi-annually one kilogram of meat is collected from locations within a 10 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.

Semi-annually one kilogram of poultry and one kilogram of eggs are collected from each of three locations with-in 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 previously sampled farms (see Figure 3).

DESCRIPTION (Continued)

1. SAMPLE COLLECTION METHODOLOGY (Continued)

E. Human Food Crops Human food crops are collected during the late summer harvest season at locations previously sampled, two types if available. One kilogram each, of of fruits and/or vegetables from 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 broadleaf type vegetable from each location. The fruits and vegetables are chilled prior to shipping and shipped fresh in insulated containers (see Figure 3).

F. Soil Samples Soil samples are required once every three years.

No regular samples were collected during 1978.

Soil samples will be collected again during the 1980 sample season. Special soil samples were collected in November 1979. These samples are discussed in Section III.B.6.

G. 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 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 loca-tion 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.

DESCRIPTION (Continued)

1. SAMPLE COLLECTION METHODOLOGY (Continued)

H. Shoreline Sediments One kilogram of shoreline sediment sample is collected at one on-site location and one off-site location. The samples are placed in plastic bags, sealed and shipped for analysis in insulated containers.

Cladaphora The species glomerata is the dominate species of clada-phora in collections in the NMP vicinity. Cladaphora is a long filamentous alga attached by a holdfast to rocks and other submerged substrates. Colonization and propagation of cladaphora extends out to a depth of about 20 feet, and the long, growing strands of cladaphora in water 5 feet deep or less are constantly

'eing broken off by wave activity. Maximum growth usually occurs in water about 10-15 feet deep, but this will vary, depending upon turbidity (Ãezernak et al 1974). Growth of cladaphora begins in late May, reaches a peak in late June or early July, and declines during the warmer summer period of late July and early August (Storr and Sweeney 1971) . As temperatures drop, a secondary peak may occur in late August. Growth ceases in September due to decreasing light and temperature.

Cladaphora samples are collected in the spring and fall season from two on-site locations and one off-site location. Cladaphora is collected from natural substrates. The cladaphora is scraped from the sub-strates into sample containers, labeled, frozen and shipped in insulated containers for off-site analysis.

TLD (direct radiation)

Thermoluminescent dosimeters (TLD's) are used to measure direct radiation in the JAP/NMP-1 environment. The TLD stations are placed around the site using a three zone

. division. The first group of TLD's are located within the 'site boundary and are called "on-site" TLD's. The second set of TLD's are called "site boundary" stations and are located at approximately the site perimeter.

The third division of TLD stations are the "off-site" stations, located at the off-site air monitoring stations.

DESCRIPTION (Continued)

1. SAMPLE COLLECTION METHODOLOGY (Continued)

J. TLD (direct radiation) (Continued)

Each TLD set is made up of 2 CaS04 dosimeters (2 chips per dosimeter), sealed in a polethylene package to insure dosimeter integrity. The TLD packages are further protected by placement in plexiglass "birdhouses" or by tape sealing to supporting surfaces. The dosimeters are collected, replaced and evaluated on a quarterly basis.

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

3. CHANGES IN THE 1979 SAMPLE PROGRAM A. An additional milk sample location was added to the 1979 sampling program. This farm was previously sampled during the 1977 program,"but chose not to participate in the 1978 sampling program. This additional sample station is designated as location number 8 (see Figure 4). This same sample station was designated as station number 4 in the 1977 Environmental Report. Only I-131 analysis was performed on this sample location.

B. 1979 sample results reported as "less than" (<)

represent the lower limits of detection (LLD).

LLD is defined by the "USNRC Branch Technical Positi'on revision 1, November 1979 " as the smallest concentration of radioactive material in the sample that will yield a net count (above system background) that will be detected with 95~~ probability with only 5~a probability of falsely concluding that a blank observation represents a "real signal". Sample data reported in the 1979 report as "less than" results were calculated using 4.66 times the standard deviation of the background count rate or of the counting rate of a blank sample where appropriate. Sample data reported as "less than" results prior to the 1979 sample program were calculated based on 3.0 times the standard deviation of the background count rate.

r DESCRI PTION (Continued)

3. CHANGES IN THE 1979 SAMPLE PROGRAM (Continued)

C. Lower Limits of Detections for airborne radioiodine (I-131) analysis reported for 1979 are decay corrected to end of sample period. Previous airborne I-131 analysis results were decay corrected to the mid-point of sample collection.

D. Amendment No. 29 to License DPR-63, date of issuance 3/26/79, changed the following portions of the environmen-tal monitoring program:

1) Aquatic a) Mollusks, gammarus, and periphyton were deleted.

Periphyton was replaced with cladaphora.

b) Bottom sediments were changed to shoreline sediments. Two on-site locations were changed to one.

2) Terrestrial a) Monthly milk composites are no longer required.

All analyses are performed on a single monthly collection.

b) Particulate filters are divided into two on-site and two off-site composites instead of one and one respectively.

EVALUATION OF ENVIRONMENTAL DATA A. Lake Program Tables 3 through 7 list the results of radiological analysis of aquatic media.

1) Cladaphora - Table 3 Cladaphora samples were collected twice during the 1979 sampling season. Collections were made on 6/19 and 8/16.

Analysis performed on the first collections indicated detectable concentrations of Mn-54, Co-58, Co-60, Cs-134, Cs-137, Ce-144. Concentrations of K-40, Ra-226, Be-7, Th-232 were also detected. The first group of nuclides is of interest in that these are normally associated with nuclear plant operations, while the second group is considered to be natural occurring. Co-137, Mn-54, Co-60 concentrations from the 03 transect were detected in quantities that may be of possible significance. These nuclides were in excess of 10 times the control station value (00

'transect). Reference LER 79-021.

Analytical results on the second set of samples indicated only Cs-137 as being of possible signifi-cance. The concentrations of this nuclide on the 02 transects was 5 times the control station value; no LER was required.

2) Shoreline Sediment - Table 4 Shoreline sediments were collected on 7/3/79 and 12/3/79 at one off-site (00) and one on-site (02) location. Analytical'results indicated concentrations

'of Cs-137, Ra-226, Th-232. The Cs-137 levels were most probably the result of fallout in that the on-site and off-site concentrations were of the same order.

EVALUATION OF ENVIRONMENTAL DATA (Continued)

A. Lake Program (Continued)

3) Fish - Table 5 A total of 23 samples were collected during 1979.

Collections were made in the spring and fall. White perch, yellow perch, and white sucker were the most abundant species with rainbow smelt present in only 2 collections.

The predominant nuclide detected was again Cs-137.

Only one on-site sample (yellow perch collected 5/79 on the 02 transect) showed concentrations of possible significance. Cs-134 and Cs-137 levels were found to be greater than 2 times the control value (white perch).

4) Lake lfater - Monthly and Quarterly Composites-Tables 6, 6A, 6B and 7 Lake water samples were analyzed for gross beta concentrations (6), gamma emitters (6A), solids and pH (6B), and H-3, Sr-89, and Sr-90 (7) .

Analytical results for the lake water samples indicated no evidence of plant related environ-mental impact.

Gross beta analyses showed a few instances where indicator locations were greater than 2 times control values (OSNP). These were the NMP inlet for'February and August, the NMP discharge for April, August, and September; and the JAF inlet for August.

Ge(Li) analyses showed indicator location greater than 2 times control values for Cs-137 in the March NMP inlet and-discharge composites and the April, June, and December discharge samples.

H-3 concentrations were greater than 2 times the control value in the 2nd quarter NMP and JAF discharge- composites.

EVALUATION OF ENVIRONMENTAL DATA (Continued)

B. Land Program The results of sample analyses for the 1979 reporting period are included in Tables 8 through 18.

Air Particulates Tables 8 and 9 Tables 8 and 9 give the results of the air particulate gross beta concentrations for the 6 off-site and 9 on-site stations respectively.

The quarterly averages for gross beta concentra-tions (pCi/m~) are as follows:

Off-Sites On-Sites 1st Qtr. 0.042 . 0.031 2nd Qtr.

3rd Qtr.

4th Qtr.

0. 101, 0.106 0.045

0. 072

0. 080 0.037 No significant levels of gross beta activities were detected during the 1979 collections. Normal flucuations were observed as is evident in the above listed quarterly averages. The concentration during the late spring, summer, and early fall months have historically been higher than the winter months.

2) Monthly Particulate Composites - Tables 10 and 10A For the first 3 months of 1979, particulate filters were composited into one off-site and one on-site composite. After a ETS amendment effective April 1, 1979 (NMP-1 only), filters were broken down into two on-site and two off-site composites.

In the January and February composites, concentrations of Be-7, Co-60, Cs-137, Ce-141, Ce-144, Mn-54, Ru-103, Ru-106 were detected. In the remaining composites only

'e-7, Cs-137, and Ce-144 were detected. Co-60 was also detected in March on-site and the February off-site, "however, it should be noted that the associated errors were on the order of 50 to 60'o.

None of the detected concentrations was of any signi-ficance. The concentrations of Cs-137, Ce-141, and Ce-144 may be attributed to sources other than the nuclear plant operation.

B. Land Program (Continued)

3) Airborne Radioiodine (I-131) - Tables ll and 12 The results of the I-131 (charcoal cartridge) for the six off-site and nine on-site stations are pre-sented in Tables ll and 12 respectively.

The quarterly averages for I-131 concentrations (pCi/m3) are as follows:

Off-Site On-Site 1st Qtr. <0.023 <0. 020 2nd Qtr. <0. 027 <0. 019 3rd Qtr. <0. 024 <0. 018 4th Qtr. <0. 022 <0. 018 7

During the 1979 program, no airborne radioiodine was detected at any of the 15 environmental stations.

4) TLD's (Environmental Dosimetry) - Table 13 The reported dose rates are the average of 4 independent readings. Each TLD station or location is composed of 2 individual TLD's, with each TLD containing 2 distinct dosimeters.

The TLD's are broken down into 3 groups for reporting purposes. The groups are on-site, off-site and site boundary (see TLD location maps, Figures 1 and 2).

The net doses at the site boundary (site boundary average minus off-site average) were as follows:

QUARTER. SITE BOUNDARY DOSE (mrem) 0.0 0.0 0.6 0~0 The total site boundary dose for 1979 was less than 1 mrem. Dosimeters 31, 32, 39 and 40 are locations within the NMP-1 restricted area near the Radwaste Building and are influenced by waste trucks being loaded in the building or parked nearby. Dosimeters 27 through 30 are located within the FitzPatrick plant restricted area and are affected by waste trucks being loaded in or parked near the Fitzpatrick Radwaste Building.

EVALUATION OF ENVIRONMENTAL DATA (Continued)

B. Land Program (Continued)

4) Dosimeter ¹35, which is located in the northeastern section of the Nine Mile Unit ¹2'onstruction site, showed an increase from 16 mrem for the first quarter 1979 to 179 mrem for the second quarter 1979. An investigation as to the possible causes for the in-crease in exposure revealed that radiographing of welds in the general vicinity of the dosimeter location occurred during this period. The D-1 on-site environ-mental radiation monitor also recorded the presence of an increased dose rate during the month of June 1979 due to the radiography nearby. The radiography that was "recorded by dosimeter ¹35 occurred from May 25 to June 27. The radiography activity was, done by 3 crews on an around the clock basis using a 100 Ci Iridium source. Approximately 6722 radiographs were taken, varying from a few seconds to 5 minutes in exposure time. No increase in radiation exposure to the general public resulted from the radiographic'esting.

5) Radiation Monitors - Table 14 Environmental radiation monitors are located in 10 of the 15 air monitoring environmental stations. Each of the on-site environmental monitoring stations contain a radiation monitor and in addition, the C off-site monitoring station contains a similar monitor. The radiation monitors consists 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 plant.

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 poor sensitivity of the monitors (environmentally speaking) no comparisons are made between the radiation monitor readings and the readings from environmental TLDs.

Milk - Tables 15 and 16 Milk samples were collected monthly from each of 5 farms and analyzed for I-131, gamma emitters, and Sr-90. I-131 results are found on Table 15. Gamma analysis and Sr-90 results are found on Table 16.

EVALUATION OF ENVIRONMENTAL DATA (Continued)

B. Land Program (Continued)

6) Milk samples were taken beginning with the month of May and continued through the month of December.

Milk sampling was not conducted from January through April because local dairy herds are not consistently on open pasture.

No concentrations of I-131 were detected in the 1979 milk samples. All I-131 analytical results were reported as lower limits of detection. The comparison of 1979 milk I-131 data showed a decrease in I-131 levels in milk from previous years during which samples were taken. It should be noted that previous data is biased by the presence of I-131 concentrations resulting from the detonation of nuclear devices in the atmosphere, while such results are not part of 1977, 1978 and 1979 data. 7 Potassium - 40 (K-40) was the most abundant nuclide detected in the milk samples collected in 1979. K-40 was detected in every sample and ranged in concentration from 960 to 1600 pCi/1. K-40 is a naturally occurring isotope and is found in many of the environmental media sampled.

Cesium 137 (Cs-137) was a second nuclide found in the majority of milk sample collected. The indicator stations results showed Cs-137 concentrations ranged in activity from 3.2 to 53.0 pCi/1.

The five used as sampling locations are located within a ten mile radius of the site and are termed indicator stations. The control location (¹13) is located 18 miles SSlP of the site. It is considered to be outside of the influence of site releases. One of the milk sample stations (¹25) located within the 10 mile radius of the site showed an elevated concentration of Cs-137 in the September sample. This level of 53.0 pCi/1, was in excess of 10 times the control value (Reference LER ¹79-024). In an effort to determine the source of the elevated Cs-137 levels in the milk pathway, plant and site parameters during the sample time period were studied. In addition, extra milk samples were collected past the normal grazing season and will continue to be taken until the end of the 1980 grazing season. Each of the 5 farms routinely sampled for milk were also sampled for the related media of soil, pasture grass and animal feed. Stored feed samples were also collected at each of the farms in the form of grain, hay, corn silage and haylage. Feed sample collections were made on 1/7/80, 2/12/80 and 3/3/80. At'his

6) time no definite conclusions have been made as to the source of the identified Cs-137 in the milk samples. Investigations into the site parameters have been conducted and do not indicate that the plant is the total source of the Cs-137.

The results of completed samples are included in this report in Tables 19 through 23. Analyses of these samples show some unexpected results., The soil sample collected at the Control Station contained approximately twice the concentration of Cs-137 as did the soil from the indicator station with the highest concentration of Cs-137 in the milk (Control = 1.3 pCi/g, Indicator =

0.72 pCi/g). Pasture grass samples from the same two sample locations showed approximately equal concentrations of Cs-137. The control station (¹13) grass sample con-tained 0.11 pCi/g and the indicator station (¹25) con-tained a concentration of 0.14 pCi/g. Table 23 contains the results of analyses performed on the 1/7, 2/12, and 3/3/80 samples. Cs-137 was found in most samples collected at indicator location ¹25. Cs-137 was also detected intermittently at other indicator locations. None of the concentrations appear significant when compared with the control location. The result of the additional milk samples are presented in Table 21 and 22. The Cs-137 levels in milk from location ¹25 are still higher than the control location.and the other indicator locations but levels are in line with past observations.

In order to obtain an independent analysis of the available data, a consultant has been contracted.

The consultant will perform an evaluation of the Cesium concentrations in the environmental milk samples and the environmental signficance of these Cesium con-centrations. The scope of work for the evaluation is comprised of five tasks. Task I will be a data review which addresses results from the site environmental program, plant operating and release data, radiological monitoring data from other sources and site meterological data. Task II covers the statistical evaluation of assembled data. Task III is the assessment of facility contribution to milk Cesium levels. Task IV is the evaluation of the analysis contractor performance and Task V will be the writing of a final report.

7) . Milch Animal Census - Table 17 The number of milch animal locations within a ten mile radius of the plant is presented in Table 17. Self-addressed post cards are sent to each farm within a ten mile radius. After 4 weeks if no response is received, telephone contact is made.

8) Human Food Crops - Table 18 The results of analysis performed on meat, poultry, eggs and food crops are shown in Table 18. Human food crop analysis for I-131 showed no detectable concentrations with LLD values ranging from <0.024 to <0. 030 pCi/g (wet) . All analysis for I-131 were performed within one half-life. Slight traces of Cs-137 were found in 7 of the meat samples collected.

Cs-137 was also detected in one produce sample. The detected Cs-137 levels are attributed to atmospheric fallout and have been detected in similar concentrations in previous years.

C. Exceptions to the Program 1

Meat samples were collected at only one location during the spring sampling period. Attempts were made to collect the required samples from 4/23/79 to 6/6/79.

Efforts to identify possible sample locations were made by weekly phone calls to the local meat market and individual farmers.

The first meat sample was obtained on S/24/79 and a second meat sample was obtained on 7/3/79. The second sample was a pork sample being butchered because of poor health and was obtained outside the required sampling time frame (spring sample period of 4/23/79 to 6/6/79). A third meat sample was collected on 8/2/79 which was also outside the spring sample period.

The difficulty in obtaining the required number of samples may be attributed to several factors. First the number of animals raised for meat and located within the ten mile radius of the plant is not ex-tensive. Secondly, butchering of animals is not always performed at the local meat market. Third, and most significant is the fact that the vast majority of meat is butchered in the fall so animals can graze in pasture for the summer to economically increase the meat yield.

The collection of spring meat samples has historically been a difficult sample media to obtain due to seasonal unavailability.

2) On ll/15/79 at 0830 electrical power was lost to seven of the nine on-site environmental stations (D2, E, F, H, I, J, K). On-site power was restored at 1145. This resulted in a total power loss of 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> and 15 minutes. The power loss was due to a planned power line interruption to facilitate the transport of the 9 Mile Point Unit No. 2 reactor vessel to the construction site. The interruption of power to the environmental station was required so the power lines crossing the delivery path of the reactor vessel could be temporarily removed allowing safe passage of the moving equipment.

A review of station and,.site releases during this time period showed no increase or unusual variation from normal operating conditions. As immediate corrective action, each effected monitor was inspected to ensure that power had been successfully restored and the cabinet equipment was functioning as intended.

The environmental significance of this event is con-sidered to be minor, and as having no effect on the quality of the site environmental program.

3) The required milk I-131 analysis'ensitivity of 0.5 pCi/1 was exceeded on five analyses performed during the 1979 program. Analyses results which exceeded the required sensitivity ranged from 0.532 to 0.69 pCi/1.

The lower sensitivities were not routine and represent only twelve percent of the analyses performed. The decrease in sensitivity was the result of two factors, the first being the use of a 4.66 sigma confidence level in calculating the LLD and secondly, the result of periodic low chemical yield (<70~~) in the operation process.

Corrective action has been identified and initiated by the analysis contractor.

NINE MILE POINT UNIT I ANNUAL ENVIRONMENTAL OPERATING REPORT INTRODUCTION This report is submitted in accordance with Section B to DPR-63, Docket 50-220.

DESCRIPTION The required sample collection and analysis schedule for NMP-1 is listed in Tables 1 and 2.

The sample collections for the radiological program are performed by two groups. Texas Instruments Incorporated, Ecological Services Branch (TIES) performs much of the environmental sampling. TIES is presently performing the Nine Mile Point Aquatic Ecology Study at the site. 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 NMPNS staffs.

1. SAMPLE COLLECTION METHODOLOGY A. Lake llater The two indicator stations are the respective inlet canals at JAFNPP and 'NMPNS. These samples are com-posited using continuously running pumps which dis-charge into large collection tanks. These tanks are empti'ed 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 large sample bottle.

Quarterly composite samples are made up from aliquots of monthly samples.

B. Air Particulate/Iodine 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 2 x 1 charcoal cartridge used to absorb airborne radioiodine. The samplers run continuous'ly and the charcoal cartridges and particulate filters are changed on a weekly basis.

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

l~'a DESCRIPTION (Continued)

1. SAMPLE COLLECTION METHODOLOGY (Continued)

B. Air Particulate/Iodine (Continued)

The air sampling stations are located in two rings surrounding the site. The on-site locations ring the terrestrial area around the plants inside the site boundary.

The on-site sampling network is composed of 9 stations. The off-site air monitoring locations range 6 to 17 miles from the site and is composed of 6 stations. Air monitoring locations are shown on Figures 1 and 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 agitated from 3 to 5 minutes to assure a homogenous mixture of milk and butterfat. Three gallons are collected during the first week of each month from each of the five farms. The samples are frozen and shipped to the analytical contractor within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> of collection in insulated shipping containers. The milk sampling locations are found on Figure 4. (See Table 15 for identification of locations sampled.)

D. Meat, Poultry and Eggs Semi-annually one kilogram of meat is collected from locations within a 10 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.

Semi-annually one kilogram of poultry and one kilogram of eggs are collected from each of three locations with-in 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 previously sampled farms (see Figure 3) .

DESCRIPTION (Continued)

1. SAMPLE COLLECTION METHODOLOGY (Continued)

E. Human Food Crops Human food crops are collected during the late summer harvest season at locations previously sampled, if 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 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 broadleaf type vegetable from each location. The fruits and vegetables are chilled prior to shipping and shipped fresh in insulated containers (see Figure 3).

.F. Soil Samples Soil samples are required once every three years.

No regular samples were collected during 1978.

-Soil samples will be collected again during the 1980 sample season. Special soil samples were collected in November 1979. These samples are discussed in Section III.B.6.

G. 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 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 loca-tion 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.

'Jg t DESCRIPTION (Continued)

1. SAMPLE COLLECTION METHODOLOGY (Continued)

H. Shoreline Sediments One kilogram of shoreline sediment sample is collected at one on-site location and one off-site location. The samples are placed in plastic bags, sealed and shipped for analysis in insulated containers.

Cladaphora The species glomerata is the dominate species of clada-phora in collections in the NMP vicinity. Cladaphora is a long filamentous alga attached by 'a- holdfast. to rocks and other submerged substrates. Colonization and propagation of cladaphora extends out to a depth of about 20 feet, and the long, growing strands of cladaphora in water 5 feet deep or less are constantly

'eing broken off by wave activity. Maximum growth usually occurs in water about 10-15 feet deep, but this will vary, depending upon turbidity (lfezernak et al 1974). Growth of cladaphora begins in late May, reaches a peak in late June or early July, and declines during the warmer summer period of late July and early August (Storr and Sweeney 1971). As temperatures drop, a secondary peak may occur in late August. Growth ceases in September due to decreasing light and temperature.

Cladaphora samples are collected in the spring and fall season from two on-site locations and one off-site location. Cladaphora is collected from natural substrates. The cladaphora is scraped from the sub-strates into sample containers, labeled, frozen and shipped in insulated containers for off-site analysis.

TLD (direct radiation)

Thermoluminescent dosimeters (TLD's) are used to measure direct radiation in the JAF/NMP-1 environment. The TLD stations are placed around the site using a three zone division. The first group of TLD's are located within the site boundary and are called "on-site" TLD's. The second set of TLD's are called "site boundary" stations and are located at approximately the site perimeter.

The third division of TLD stations are the "off-site" stations, located at the off-site air monitoring stations.

e DESCRIPTION (Continued)

1. SAMPLE COLLECTION METHODOLOGY (Continued)

J. TLD (direct radiation) (Continued)

Each TLD set is made up of 2 CaS04 dosimeters (2 chips per dosimeter), sealed in a polethylene package to insure dosimeter integrity. The TLD packages are further protected by placement in plexiglass "birdhouses" or by tape sealing to supporting surfaces. The dosimeters are collected, replaced and evaluated on a quarterly basis.

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

3. CHANGES IN THE 1979 SAMPLE PROGRAM A. An additional milk sample location was added to the 1979 sampling program. This farm was previously sampled during the 1977 program,"but chose not to participate in the 1978 sampling program. This additional sample station is designated as location number 8 (see Figure 4). This same sample station was designated as station number 4 in the 1977 Environmental Report. 'nly I-131 analysis was performed on this sample location.

B. 1979 sample results reported as "less than" (<)

represent the lower limits of detection (LLD).

LLD is defined by the "USNRC Branch Technical Positi'on revision 1, November 1979 " as the smallest concentration of radioactive material in the sample that will yield a net count (above system background) that will be detected with 95~a probability

, with only 5~ probability of falsely concluding that a blank observation represents a "real signal". Sample data reported in the 1979 report as "less than" results were calculated using 4.66 times the standard deviation of the background count rate or of the counting rate of' blank sample where appropriate. Sample data reported as "less than" results prior to the 1979 sample program were calculated based on 3.0 times the standard deviation of the background count rate.

DESCRIPTION (Continued)

3. CHANGES IN 1HE 1979 SAMPLE- PROGRAM (Continued)

C. Lower Limits of Detections for airborne radioiodine (I-131) analysis reported for 1979 are decay corrected to end of sample period. Previous airborne I-131 analysis results were decay corrected to the mid-point of sample collection.

\

D. Amendment No. 29 to License DPR-63, date of issuance 3/26/79, changed the following portions of the environmen-tal monitoring program:

1) Aquatic a) Mollusks, gammarus, and periphyton were deleted.

Periphyton was replaced with cladaphora.

b) Bottom sediments were changed to shoreline sediments. Two on-site locations were changed to one.

2) Terrestrial a) Monthly milk composites are no longer required.

All analyses are performed on a single monthly collection.

b) Particulate filters are divided into two on-site and two off-site composites instead of one and one respectively.

EVALUATION OF ENVIRONMENTAL DATA A. Lake Program Tables 3 through 7 list the results of radiological analysis of aquatic media.

1) Cladaphora Table 3 Cladaphora samples were collected twice during the 1979 sampling season. Collections were made on 6/19 and 8/16.

Analysis performed on the first collections indicated detectable concentrations of Mn-54, Co-58, Co-60, Cs-134, Cs-137, Ce-144. Concentrations of K-40, Ra-226, Be-7, Th-232 were also detected. The first group of nuclides is of interest in that these are normally associated with nuclear plant operations, while the second group is considered to be natural occurring. Co-137, Mn-54, Co-60 concentrations from the 03 transect were detected in quantities that may be of possible significance. These nuclides were in excess of 10 times the control station value (00 transect). Reference LER 79-021.

Analytical results on the second set of samples indicated only Cs-137 as being of possible signifi-cance. The concentrations of this nuclide on the 02 transects was 5 times the control station value; no LER was required.

2) Shoreline Sediment - Table 4 Shoreline sediments were collected on 7/3/79 and 12/3/79 at one off-site (00) and one on-site (02) location. Analytical results indicated concentrations

'of Cs-137, Ra-226, Th-232. The Cs-137 levels were most probably the result of fallout in that the on-site and off-site concentrations were of the same order.

It EVALUATION OF ENVIRONMENTAL DATA (Continued)

A. Lake Program (Continued)

3) Fish - Table 5 A total of 23 samples were collected during 1979.

Collections were made in the spring and fall. white perch, yellow perch, and white sucker were the most abundant species with rainbow smelt present in only 2 collections.

The predominant nuclide detected was again Cs-137.

Only .one on-site sample (yellow perch collected S/79 on the 02 transect) showed concentrations of possible significance. Cs-134 and Cs-137 levels were found to be greater than 2 times the control value (white perch).

.4) Lake Water - Monthly and Quarterly Composites-Tables 6, 6A, 6B and 7 Lake water samples were analyzed for gross beta concentrations (6), gamma emitters (6A), solids and pH (6B), and H-3, Sr-89, and Sr-90 (7).

Analytical results for the lake water samples indicated no evidence of plant related environ-mental impact.

Gross beta analyses showed a few instances where indicator locations were greater than 2 times control values (OSNP). These were the NMP inlet for February and August, the NMP discharge for April, August, and September; and the JAF inlet for August.

Ge(Li) analyses showed indicator location greater than 2 times control values for Cs-137 in the March NMP inlet and discharge composites and the April, June, and December discharge samples.

H-3 concentrations were greater than 2 times the control value in the 2nd quarter NMP and JAF discharge composites.

s EVALUATION OF ENVIRONMENTAL DATA (Continued)

B. Land Program The results of sample analyses for the 1979 reporting period are included in Tables 8 through 18.

Air Particulates - Tables 8 and 9 Tables 8 and 9 give the results of the air particulate gross beta concentrations for the 6 off-site and 9 on-site stations respectively.

The quarterlv averages for gross beta concentra-tions (pCi/m ) are as follows:

Off-Sites On-Sites 1st Qtr. 0.042 0. 031 2nd Qtr. 0.106 0. 072 3rd Qtr. 0.101 0. 080 4th Qtr. 0.045 0.037 No significant levels of gross beta activities were detected during the 1979 collections. Normal flucuations were observed as is evident in the above listed quarterly averages. The concentration during the late spring, summer, and early fall months have historically been higher than the winter months.

2) Monthly Particulate Composites - Tables 10 and 10A For the first 3 months of 1979, particulate filters were composited into one off-site and one on-site composite. After a ETS amendment effective April 1, 1979 (NMP-1 only), filters were broken down into two on-site and two off-site composites.

In the January and February composites, concentrations of Be-7, Co-60, Cs-137, Ce-141, Ce-144, Mn-54, Ru-103, Ru-106 were detected. In the remaining composites only

'e-7, Cs-137, and Ce-144 were detected. Co-60 was also detected in March on-site and the February off-site, "however, it should be noted that the associated errors were on the order of 50 to 60'o.

None of the detected concentrations was of any signi-ficance. The concentrations of Cs-137, Ce-141, and Ce-144 may be attributed to sources other than the nuclear plant operation.

The quarterly averages for I-131 concentrations (pCi/m3) are as follows:

Off-Site On-Site 1st Qtr. <0.023 <0. 020 2nd Qtr. <0. 027 <0. 019 3rd Qtr. <0. 024 <0. 018 4th Qtr. <0. 022 <0. 018 During the 1979 program, no airborne radioiodine was detected at any of the 1S environmental stations.

4) TLD's (Environmental Dosimetry) - Table 13 The reported dose rates are the average of 4 independent readings. Each TLD station or location is composed of 2 individual TLD's, with-each TLD containing 2 distinct dosimeters.

The TLD's are broken down into 3 groups for reporting purposes. The groups are on-site, off-site and site boundary (see TLD location maps, Figures 1 and 2).

The net doses at the site boundary (site boundary average minus off-site average) were as follows:

UARTER SITE BOUNDARY DOSE (mrem) 0.0 0.0 0.6 0.0 The total site boundary dose for 1979 was less than 1 mrem. Dosimeters 31, 32, 39 and 40 are locations within the Nh/P-1 restricted area near the Radwaste Building and are influenced by waste trucks being loaded in the building or parked nearby. Dosimeters 27 through 30 are located within the FitzPatrick plant restricted area and are affected by waste trucks being loaded in or parked near the FitzPatrick Radwaste Building.

4) Dosimeter 835, which is located in the northeastern section of the Nine Mile Unit 02 construction site, showed an increase from 16 mrem for the first quarter 1979 to 179 mrem for the second quarter 1979. An investigation as to the possible causes for the in-crease in exposure revealed that radiographing of welds in the general vicinity of the dosimeter location occurred during this period. The D-1 on-site environ-mental radiation monitor also recorded the presence of an increased dose rate during the month of June 1979 due to the radiography nearby. The radiography that was recorded by dosimeter 835 occurred from May 25 to June 27. The radiography activity was done by 3 crews on an around the clock basis using a 100 Ci Iridium source. Approximately 6722 radiographs were taken, varying from a few seconds to 5 minutes in exposure time. No increase in radiation exposure to the general public resulted from the radiographic'esting.

5) Radiation Monitors Table 14 Environmental radiation monitors are located in 10 of the 15 air monitoring environmental stations. Each of the on-site environmental monitoring stations contain a radiation monitor and in addition, the C off-site monitoring station contains a similar monitor. The radiation monitors consists 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 plant.

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 poor sensitivity of the monitors (environmentally speaking) no comparisons are made between the radiation monitor readings and,the readings from environmental TLDs.

6) Milk - Tables 15 and 16 Milk samples were collected monthly from each of 5 farms and analyzed for I-131, gamma emitters, and Sr-90. I-131 results are found on Table 15. Gamma analysis and Sr-90 results are found on Table 16.

6) Milk samples were taken beginning with the month of May and continued through the month of December.

Milk sampling was not conducted from January through April because local= dairy herds are not consistently on open pasture.

No concentrations of I-131 were detected in the 1979 milk samples. All I-131 analytical results were reported as lower limits of detection. The comparison of 1979 milk I-131 data showed a decrease in I-131 levels in milk from previous years during which samples were taken. It should be noted that previous data is biased by the presence of I-131 concentrations resulting from the detonation of nuclear devices in the atmosphere, while such results are not part of 1977, 1978 and 1979 data.

Potassium - 40 (K-40) was the most abundant nuclide detected in the milk samples collected in 1979. K-40 was detected in every sample and ranged in concentration from 960 to 1600 pCi/1. K-40 is a naturally occurring isotope and is found in many of the environmental media sampled.

Cesium - 137 (Cs-137) was a second nuclide found in the majority of milk sample collected. The indicator stations results showed Cs-137 concentrations ranged in activity from 3.2 to 53.0 pCi/1.

The five used as sampling locations are located within a ten mile radius of the site and are termed indicator stations. The control location (¹13) is located 18 miles SSI< of the site. It is considered to be outside of the influence of site releases. One of the milk sample stations (¹25) located within the 10 mile radius of the site showed an elevated concentration of Cs-137 in the September sample. This level of 53.0 pCi/1, was in excess of 10 times the control value (Reference LER ¹79-024). In an effort to determine the source of the elevated Cs-137 levels in the milk pathway, plant and site parameters during the sample time period were studied. In addition, extra milk samples were collected past the normal grazing season and will continue to be taken until the end of the 1980 grazing season. Each of the 5 farms routinely sampled for milk were also sampled for the related media of soil, pasture grass and animal feed. Stored feed samples 'were also collected at each of the farms in the form of grain, hay, corn silage and haylage. Feed sample collections were made on 1/7/80, 2/12/80 and 3/3/80. At this

6) time no definite conclusions have been made as to the source of the identified Cs-137 in the milk samples. Investigations into the site parameters have been conducted and do not indicate that the plant is the total source of the Cs-137.

The results of completed samples are included in this report in Tables 19 through 23. Analyses of these samples show some unexpected results. The soil sample collected at the Control Station contained approximately twice the concentration of Cs-137 as did the soil from the indicator station with the highest concentration of Cs-137 in the milk (Control = 1.3 pCi/g, Indicator =

0.72 pCi/g). Pasture grass samples from the same two sample locations showed approximately equal concentrations of Cs-137. The control station (¹13) grass sample con-tained O.ll pCi/g and the indicator station (¹25) con-tained a concentration of 0. 14 pCi/g. Table 23 contains the results of analyses performed on the 1/7, 2/12, and 3/3/80 samples. Cs-137 was found in most samples collected at indicator location ¹25. Cs-137 was also detected intermittently at other indicator locations. None of the concentrations appear significant when compared with the control location. The result of the additional milk samples are presented in Table 21 and 22. The Cs-137 levels in milk from location ¹25 are still higher than the control location and the other indicator locations but levels are in line with past observations.

In order to obtain an independent analysis of the available data, a consultant has been contracted.

The consultant will perform an evaluation of the Cesium concentrations in the environmental milk samples and the environmental signficance of these Cesium con-centrations. The scope of work for the evaluation is comprised of five tasks. Task I will be a data review which addresses results from the site environmental program, plant operating and release data, radiological monitoring data from other sources and site meterological data. Task II covers the statistical evaluation of assembled data. Task III is the assessment of facility contribution to milk Cesium levels. Task IV is the evaluation of the analysis contractor performance and Task V will be the writing of a final report.

7) Milch Animal Census - Table 17 The number of milch animal locations within a ten mile radius of the plant is presented in Table 17. Self-addressed post cards are sent to each farm within a ten mile radius. After 4 weeks if no response is received, telephone contact is made.

8) Human Food Crops - Table 18 The results of analysis performed on meat, poultry, eggs and food crops are shown in Table 18. Human food crop analysis for I-131 showed no detectable concentrations with LLD values ranging from <0.024 to <0.030 pCi/g (wet). All analysis for I-131 were performed within one half-life. Slight traces of Cs-137 were found in 7 of the meat samples collected.

Cs-137 was also detected in one produce sample. The detected Cs-137 levels are attributed to atmospheric fallout and have been detected in similar concentrations in previous years.

C. Exceptions to the Program Meat samples were collected at only one location during the spring sampling period. Attempts were made to collect the required samples from 4/23/79 to 6/6/79.

Efforts to identify possible sample locations were made by weekly phone calls to the local meat market and individual farmers.

The first meat sample was obtained on 5/24/79 and a second meat sample was obtained on 7/3/79. The second sample was a pork sample being butchered because of poor health and was obtained outside the required sampling time frame (spring sample period of 4/23/79 to 6/6/79). A third meat sample was collected on 8/2/79 which was also outside the spring sample period.

The difficulty in obtaining the required number of samples may be attributed to several factors. First the number of animals raised for meat and located within the ten mile radius of the plant is not ex-tensive. Secondly, butchering of animals is not always performed at the local meat market. Third, and most significant is the fact that the vast majority of meat is butchered in the fall so animals can graze in pasture for the summer to economically increase the meat yield.

The collection of spring meat samples has historically been a difficult sample media to obtain due to seasonal unavailability.

C. Exceptions to the Program (Continued)

2) On ll/15/79 at 0830 electrical power was lost to seven of the nine on-site environmental stations (D2, E, F, H, I, J, K). On-site power was restored at 1145. This resulted in a total power loss of 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> and 15 minutes. The power loss was due to a planned power line interruption to facilitate the transport of the 9 Mile Point Unit No. 2 reactor vessel to the construction site. The interruption of power to the environmental station was required so the power lines crossing the delivery path of the reactor vessel could be temporarily removed allowing safe passage of the moving equipment.

A review of station and site releases during this time period showed no increase or unusual variation from normal operating conditions. As immediate corrective action, each effected monitor was inspected to ensure that power had been successfully restored and the cabinet equipment was functioning as intended.

The environmental significance of this event is con-sidered to be minor, and as having no effect on the quality of the site environmental program.

3) The required milk I-131 analysis sensitivity of 0.5 pCi/1 was exceeded on five analyses performed during the 1979 program. Analyses results which exceeded the required sensitivity ranged from 0.532 to 0.69 pCi/l.

The lower sensitivities were not routine arid represent only twelve percent of the analyses performed. The decrease in sensitivity was the result of two factors, the first being the use of a 4.66 sigma confidence level in calculating the LLD and secondly, the result of periodic low chemical yield (<70%) in the operation process.

Corrective action has been identified and initiated by the analysis contractor.
