This report is submitted in accordance with Appendix A (Technical Specifications), Section 6.9.1.d to License DPR-63, Docket No. 50-220 for the Nine Mile Point Nuclear'tation Unit 1 and Section 6.9.1.7 to License NPF 69, Docket No. 50-410 for the Nine Mile Point Nuclear Station Unit 2 for the calendar year 1988.

The present sample collection and analysis schedule required by the Technical Specifications for the Nine Mile Point Nuclear Station Unit 1 and 2 (NMPNS) is listed in Table 1 and 2.

The sample collections for the radiological program are performed by two groups. EA Science and Technology Inc. (EA) performs much of the environmental sampling. EA is presently performing the Nine Mile Point Biological Monitoring Program required by the Station's SPDES Permit.

The staff required.,by EA to perform this program is used to perform the terrestrial sampling required for the site Radiological Environmental Monitoring Program (REMP). In-plant canal sampling, air sample collection and environmental TLD,collections are- performed jointly by

~

the NMPNS and the James A. FitzPatrick Nuclear Power Plant (JAFNPP) staffs.

A. Shoreline Sediment Shoreline sediment samples are collected twice per year from one area of existing or potential recreational value and from one area beyond the influence of the site. The area of potential recreational value is the only area from which samples are required by the Technical Specifications. Approximately one kilogram of shoreline sediment is obtained from areas washed by the lakeshore surf at the two locations twice per year. All samples are shipped and analyzed for gamma emitters. Optional samples may be collected from other shoreline locations at or near the site.

Shoreline sediment locations are shown on Figure 1A (refer to Table 19 for location designations and descriptions).

B. Fish Samples Available fish species are obtained from collections during the spring and fall., Samples are collected from two of four possible on-site sample transects located in the vicinity of the

(Cont'd) t th (Cont'd)

Fish Samples (Cont'd) site discharge points and one off-site sample transect.

Available species are selected under the following guidelines:

1. Samples of 0.5 to 1 kilogram of edible portions for a minimum of two species per location.

2. When two independent species are not available at all sample locations, a species may be divided into two samples for each location. This procedure may be accomplished provided that a sufficient sample size is available for the species in question at all three locations.

Selected fish samples are segregated by species and location and are processed immediately after collection. Samples are shipped frozen in insulated containers. Edible portions of samples are analyzed for gamma emitting radionuclides.

Fish sample transects are shown on Figure lA (refer to Table 19

'for location designations and descriptions).

C. Surface Water Surface water samples are taken from the respective inlet canals of the J.A. FitzPatrick facility and Niagara",Mohawk's Oswego Steam Station. The FitzPatrick facility removes water from Lake Ontario on a continuous basis and generally represents a "down-current" sampling point from the Nine Mile Point Unit 1 and Unit 2 facilities. The Oswego Steam Station inlet canal removes water from Lake Ontario at a point approximately 7.6 miles west of the site. This "up-current" location is considered a control location because of the distance from the site as well as the result of the lake current patterns and current patterns from the Oswego River located nearby (see Figure 1A).

Samples from the FitzPatrick facility are composited from automatic sampling equipment which discharges into a compositing tank. Samples are obtained from the tank monthly and analyzed for gamma emitters. Samples from the Oswego Steam Station are also composited from automatic sampling equipment which discharge to a compositing tank. Samples from this location are obtained weekly and are composited to form monthly composite samples. Monthly samples are analyzed for gamma emitters.

A portion of the samples from each of the locations is saved and composited to form quarterly composite samples for each calendar quarter. Quarterly composite samples are analyzed for tritium.

(Cont'd)

C. Surface Water (Cont'd)

In addition to the FitzPatrick and Oswego Steam Station facilities, data are presented for the Nine Mile Point Unit 1 and Unit 2 facility inlet canals and city water from the City of Oswego. The latter three locations are not required by the Technical Specifications, but are optional samples. Monthly composite samples from these three locations are analyzed for gamma emitters and quarterly composite samples are analyzed for i

tr tium ~

l Sampling for ground water and drinking water, 's found in Section 3.12.1 of the Nine Mile Point Unit 2 Technical Specifications, was not required during 1988 because these

'pathways were not applicable to the Site during the year.

Applicable sampling requirements .and conditions are presented in the Unit 2 Off-Site Dose Calculation Manual.

Surface water sample locations are shown on Figure lA (refer to Table 19 for location designations and descriptions).

D. Air Particulate/Iodine The air sampling stations required by the Technical Specifications are located in the general area'f the site boundary (within 0.7 miles) in sectors of highest calculated meteorological deposition factors (D/Q) based on historical meteorological data. These stations (R-l, R-2, and R-3) are located in the east, east-southeast, and southeast sectors as measured from the center of the Nine Mile Point Nuclear Station Unit 2 reactor building. The Technical Specifications also require that a fourth air sampling station be located in the vicinity of a year round community having the highest calculated deposition factor (D/Q) based on historical meteorological

~

data. This station is located in the southeast sector (R-4). A fifth station required by the Technical Specifications is located at a site 16.4 miles from the site in a least prevalent wind direction of northeast (R-5). This location is considered a control location. I In addition to the Technical Specification required locations, there are six other sampling stations located within the site boundary (Dl, G, H, I, J, and K). These locations generally surround the area occupied by the three generating facilities, but are well within the site boundary. One other air sampling station is located off-site in the southwest sector and is in the vicinity of the City of Oswego. Three remaining air sampling stations (D2, E and F) are located in the east-southeast, south-southeast and south sectors and range in distance from 7.2 to 9.0 miles.

D. Air Particulate/Iodine (Cont'd)

At each station, airborne particulates are collected by glass fiber filters and radioiodine by charcoal filters. Air particulate glass fiber filters are approximately two inches (47 millimeters) 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 inch charcoal cartridge used to absorb airborne radioiodine. The samplers run continuously and the charcoal cartridges and particulate filters are changed on a weekly basis, or as required by dust loading. Gross beta analysis is performed for the individual particulate filters on a weekly basis. Charcoal cartridges are analyzed weekly for radioiodine by GeLi detector.

The particulate filters are composited 'by location for gamma analyses on a monthly basis after all weekly particulate filters have been counted for gross beta- activity.

Air sampling stations are shown in Figures 1 and 2 (refer to Table 19 for location designations and descriptions).

E. TLD (direct radiation)

Thermoluminescent dosimeters (TLD's) are used to measure direct radiation (gamma dose) in the environment. TLD's are obtained from Teledyne Isotopes on a quarterly basis and are read at Teledyne Isotopes'acility in Westwood, New Jersey. Shipment control TLD's (at least two) accompany each shipment to and from the vendor's laboratory. Shipment control TLD's also accompany the TLD's when they are being placed or collected and are shielded by lead when they are not being used. TLD data results are corrected for a transit dose by use of the data from the shipment control TLD's.

Five different types of areas are evaluated by environmental TLD's. These areas'nclude on-site areas (areas within the site boundary not required by the Technical Specifications), the site boundary area in each of the sixteen meteorological sectors, an outer ring of TLD's located four to five miles from the site in eight available land based meteorological sectors, special interest TLD's located at sites of high population density and control TLD's located at sites beyond significant influence of the site. Special interest TLD's are located at or near large industrial sites, schools, proximal towns or communities or other special activity areas. Control TLD's are located to the southwest, south, south-southeast and northeast of the site at distances of 12.6 to 26.4 miles.

TLD's used during 1988 were composed of rectangular teflon wafers impregnated with 25K CaS04.'y Phosphor. These were placed in

(Cont'd)

E. TLD (direct radiation) (Cont'd) polyethylene packages to ensure dosimeter integrity. TLD packages were placed in open webbed plastic holders and were attached to supporting structures', usually trees or utility poles.

Environmental TLD locations are shown on Figures 1A, 1B, and 2 (refer to Table 19 for location designations and descriptions).

F. Milk Milk samples are collected in polyethylene bottles from a bulk storage tank at each, sampled farm. Before the sample is drawn, the tank contents are agitated from three to five minutes to assure a homogenous mixture of milk and butterfat. Two gallons are collected during the first half and second half of each month from each of the selected locations within ten miles of the site and from a control location. The samples are chilled and shipped fresh to the analytical laboratory within thirty-six hours of collection in insulated shipping containers.

The selection of milk sample locations is based on maximum deposition factors (D/Q). Deposition factors are generated from average historical meteorological data based on all licensed reactors. The Technical Specifications require three sample locations within 5.0 miles of the site with the highest calculated deposition factors. During 1988, there were no milk sample locations within 5.0 miles that could be sampled.

However, there were several optional locations beyond five miles that were sampled.

A fourth sample location required by the Technical Specifications is located in a least prevalent wind direction from the site. This location is in the southwest sector and serves as a control location.

Milk samples are collected twice per month (April December) and analyzed for gamma emitters and I-131. Samples are collected and analyzed in January March in the event I-131 is detected in November and December of the preceding year.

The milk sample locations are found on Figure 4. (refer to Table 19 for location designations and descriptions).

G. Land Use Census A land use census is- conducted to determine the utilization of land in the vicinity of the site. The land use census actually consists of two types of census. A milk animal census is

(Cont'd)

G. Land Use Census (Cont'd) conducted to identify all milk animals within a distance of 10 miles from the site. A census covering areas out to a distance of 10 miles exceeds the distance required by the Technical Specifications. This census 'is conducted during the beginning of the grazing season using road surveys, contacting local agricultural authorities, post cards, and investigating references 'from other owners.

A second type of census is a residence census. This census is conducted in order to identify the closest residence in each of the 22.5 degree meteorological sectors. A residence, for the purposes of this census, is a,residence that is occupied on a part time basis (such as a summer camp), or on a full time, year round basis. For the residence census, several of the meteorological sectors are over Lake Ontario because the site is located at the shoreline. Therefore, there are only eight sectors over land where residences are located within 3 miles.

The results of the two land use census are shown on Tables 15 and 16 and on Figures 3 and 4.

H. Food Products Food products are collected once per year during the late summer at the approximate height of the harvest season. Approximately one kilogram of a broadleaf vegetable or other broadleaf vegetation is collected from garden locations'ith the highest deposition factors (D/Q) based on average historical meteorological data. Six samples are collected from at least two sectors. Additional samples may also be obtained. Control samples are also collected from available off-site locations 9 to 20 miles distant in a least prevalent wind direction.

Control samples are of the same or of a similar type of vegetation. All samples are shipped fresh as soon as possible after collection.

Food product samples are analyzed for gamma emitters (gamma isotopic analysis). The gamma isotopic analysis also includes I-131.

Food product locations are shown on Figure 3 (refer to Table 19 for location designations and descriptions).

The Radiological Environmental Monitoring Program (REMP) samples were analyzed by Teledyne Isotopes and by the Site Environmental

(Cont'd) 2~ n (Cont'd)

Laboratory during 1988. The following samples were analyzed by the Site Environmental Laboratory:

Shoreline sediment (gamma spectral analysis)

Fish (gamma spectral analysis)

Lake water (monthly gamma spectral analysis only) filter (weekly gross beta analysis)

I Air particulate Air particulate filter (monthly gamma spectral analysis)

Airborne radioiodine cartridge (weekly gamma spectral analysis)

Milk (gamma spectral analysis only)

Food products (gamma spectral analysis)

The remainder of the sample analyses, as outlined in Table 1 and 2, were analyzed by Teledyne Isotopes.

3. h A. Program TLD N108 was added to the monitoring program on March 30, 1988. TLD 8108 is located in the vicinity of the critical off-site residence and is used to evaluate any potential direct radiation dose from the site and gaseous effluent plumes. This TLD is not a Technical Specification required TLD.

B. Program TLD 8109 was added to the monitoring program on March 30, 1988. TLD 8109 is also located in the vicinity of the critical off-site residence and is used to supplement and verify any direct radiation doses measured by TLD 8108. TLD 8109 is not a Technical Specification required TLD.

C. Program TLD 8110 was added to the monitoring program on March 31, 1988. TLD Nll0 is located 26.4 miles from the site in the south-southeast sector and is used to measure background gamma radiation doses. The data from TLD 8110 is considered control data and is used to supplement control data from TLDs 8, 14 and 49.

D. Program TLD 8111 was added to the monitoring program on March 31, 1988. TLD f/111 is located 21.8 miles from the site in the southwest sector and is used to measure background gamma radiation doses. The data from TLD Nlll is supplemental control data and is used to determine an average control dose rate in conjunction with TLD 88, 14, 49 and 110.

E. Food product location Z was added to the sample program during 1988. Location Z is in 'close proximity to location T which was sampled during both 1988. as well as 1987. The new location is approximately 1000 feet closer to the site than location T is and is in the same sector (east) as location T.

Also during 1988, food product locations N, V and S were deleted from the sampling program because of either sample unavailability or because the location had a low deposition potential as a result of the addition of location Z.

Exceptions to the 1988 sample p'rogram concerns those samples or monitoring requirements which are required by the Technical Specifications. This section implements section 3.6.20 of the Nine Mile Point Nuclear Station Unit 1 Technical Specifications and Section 3.12.1 of the Nine Mile Point Nuclear Station .Unit 2 Technical Specifications.

Air radioiodine and air particulate monitoring as the only sample media for which exceptions to the overall monitoring program

.required by the Technical Specifications were noted. None of the other. monitoring programs required by the Technical Specifications contained exceptions.

A. Air Radioiodine and Particulate Sampling Required by the Technical Specifications Environmental air sample equipment at R-3 off-site air sampling station was inoperable from 1/29/88 (1036 hours0.012 days 0.288 hours 0.00171 weeks 3.94198e-4 months ) to 2/2/88 (0833. hours). The vacuum pump was found defective and was replaced.

2. Environmental air sample equipment at R-4 off-site air sampling station was inoperable from 5/8/88 (2324 hours0.0269 days 0.646 hours 0.00384 weeks 8.84282e-4 months ) to 5/10/88 (0900 hours0.0104 days 0.25 hours 0.00149 weeks 3.4245e-4 months ). The vacuum pump was found defective and was replaced.

Other occurrences of downtime for optional air sampling stations were documented for 1988. However, these occurrences are not presented here because optional air sampling stations are not required by the Technical Specifications. Documentation includes downtime for air sampling equipment as well as env'ironmental radiation monitoring equipment.

B. Lower Limit of Detection for Environmental Samples The Technical Specifications require that environmental samples analyzed for the Radiological Environmental Monitoring Program meet the lower limits of detection (LLD) found on Table 4.6.20-1 of the Nine Mile Point Unit 1 Technical Specifications and Table 4.12.1-1 of the Nine Mile Point Unit 2 Technical Specifications. All of the 1988 environmental samples required by the Technical Specifications which showed no net activity were less than the required 'values found on Table 4.6.20-1 and Table 4.12.1-1.

C. Deviations from the Interlaboratory Comparison Program Section 3.6.21 of the Nine Mile Point Unit 1 Technical Specifications and Section 3.12.3 of the Nine Mile Point Unit 2 Technical Specifications require the site to conduct an Interlaboratory Comparison Program utilizing QC samples from the Environmental Protection Agency (EPA). This section also requires that deviations from the sample schedules be reported in the Annual Radiological Environmental Operating Report. The sample schedule is set by the EPA and includes media for which environmental samples are routinely collected and for which interlaboratory comparison samples are available from the EPA.

During 1988, sample media offered by the EPA for the Interlaboratory Comparison Program, and for which environmental samples are routinely coll'ected and analyzed, were obtained and analyzed. There were no deviations from the program. The amount of samples obtained from the EPA program was based on the maximum amount available per participant or on a ten percent or better level (percent of the ratio of EPA samples to the total required sample volume).

There were four separate groups of radionuclides that were detected in the environment during 1988. Several radionuclides could possibly fall into two of the four groups. The first of these groups is naturally occurring radionuclides. It must be realized that the environment contains a broad inventory of naturally occurring radioactive elements. Background radiation, as a function of primordial radioactive elements and cosmic radiation of solar origin, offers 'a constant exposure to the .environment, and man. These. radionuclides, such as Ra-226, Be-7 and especially K-40, account for a majority of the annual per capita background dose.

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

AL D (Cont'd)

The detonation frequency during the early 1950's produced a significant inventory of radionuclides found in the lower atmosphere as well as in ecological systems. A ban was placed on atmospheric weapons testing in 1963 which greatly reduced the inventory through the decay of short lived radionuclides, deposition, and the removal (by natural processes) of radionuclides from the food chain. Since 1963, several atmospheric weapons tests have been conducted by the People's Republic of China.

In each case, the usual radionuclides associated with nuclear detonations were detected several months afterwards, and after a peak detection period, diminished to a point where most could not be detected. The last such weapons test was conducted in October of 1980. The resulting fallout or deposition from this test had influenced the background radiation in the vicinity of the site and was very evident in many of the sample media analyzed during 1981.

Calculations from 1981 of the resulting doses to man from fallout related radionuclides in, the environment show that the contribution from such nuclides (such as Sr-90 or Cs-137) is significant and second in intensity only to natural background radiation. Quant'ities of Nb-95, Zr-95, Ce-141, Ce-144, Ru-106, Ru-103, La-140, Cs-137, Mn-54 and Co-60 were typical in air. particulate samples during 1981 and have a weapons test origin. During 1988, Cs-137 was the only radionuclide detected in environmental samples that has a weapons testing origin.

The third group of radionuclides includes those detected at the site that were a result of the Chernobyl Nuclear Plant accident. These radionuclides were first detected in May of 1986 and were found in .

samples of air particulates, air radioiodine and milk. Applicable radionuclides include I-131; Cs-134, Cs-137, Nb-95, Ru-103, Ru-106, and La-140. During 1988, Cs-137 was detected in one milk sample collected prior to the grazing season and was a result of the Chernobyl accident.

The fourth group of radionuclides are those that could be related to operations at the site. Many of these radionuclides are a by-product of both nuclear detonations and the operation of light water reactors, and therefore, make a distinction between the two. sources difficult, if not impossible. The radionuclides falling into this category (as applicable to the 1988 Nine Mile Point Radiological Environmental Monitoring Program) includes I-131 and tritium. The dose to man as a result of these radionuclides is small and significantly less than the radiation exposure from naturally occurring sources of radiation and fxom fallout.

Thus g the evaluation and interpretation of environmental data must be made at several levels including trend analysis, dose to man, etc. An attempt has been made not only to report the data collected during 1988, but also to assess the significance of the radionuclides detected in the environment as compared to natural radiation sources. It is important to note that detected concentrations of radionuclides that are possibly related to operations at the site are very small and are not an indication of environmental significance. In regards to these very small quantities, it will be further noted that at such minute

. concentrations the - assessment of the significance of detected

-10

(Cont'd) radionuclides is very difficult. Therefore, concentrations in one sample that are two times the concentration of another, for example, are not significant overall. Moreover, concentrations at such low levels may show a particular radionuclide in one sample and yet not in

'nother because of counting statistics.

The 1970 per capita dose rate (Eisenbud) was determined to be 209 mrem per year from all sources. This average dose includes such exposure sources as natural, occupational, weapons testing, consumer products, medical, etc. The 1970 per capi.ta dose rate due to natural sources was 130 mrem per year. Of this dose, approximately 20 mrem per year is received by the gonads and other soft issues and an additional 15 mrem per year is received by the bone tissue for a 70 kg (155 lb) man.

These doses (ie. 20 mrem and 15 mrem) are the result of just K-40 alone, a naturally occurring relatively high energy beta emitter (1.3 Mev)., The 1970 per capita dose rate due to the nuclear fuel cycle was 0.028 mrem per year. More recently, the nuclear fuel cycle dose was estimated by a USEPA study to be less than 0.6 mrem per year by the year 2000.(Glasstone).

Background gamma radiation around the Nine Mile Point'ite, as a result of radionuclides in the atmosphere and the ground, accounts for approximately 66 mrem per year during 1988. This dose is a result of radionuclides of cosmic origin (for example, Be-7), of a primordial origin (Ra-226, K-40, and Th-232) and, to a much smaller extent, of a man-made origin from weapons testing. A dose of 66 mrem per year, as a background dose, is significantly greater than any possible doses as a result of operations at the site during 1988.

Tables 3 through 6 show the analytical results for the aquatic media collected during the 1988 sampling program. Aquatic samples were collected at four possible indicator locations. The locations (on-site transect designations) used for on-site sampling were NMPW, NMPP (02), JAF (03),'nd NMPE. Because of the unavailability of various sample media, on-site samples may be collected from combinations of the above listed locations, when required. NMPW and NMPP may be combined into location .NMPP. NMPE and JAF may be into location JAF. Off-site samples were collected at the 'ombined

'swego Harbor area or in the general vicinity of the harbor and therefore served as control samples. Refer to Figure 1A for the location of sample transects.

Data are evaluated only from locations required by the Technical Specifications. Data from optional sample locations are not evaluated unless indicated otherwise.

Several radionuclides were detected in sediment samples using gamma spectral analysis. These radionuclides were naturally occurring primordial radionuclides. K-40 was detected at both the control location and indicator locations for both collection periods during 1988. K-40 ranged in concentration from 10.7 pCi/g (dry) to 12.2 pCi/g (dry) at the control location and 10.4 pCi/g (dry) to 14.7 pCi/g (dry) at the indicator locations.

Ra-226 and AcTh-228, in addition to K-40, were also detected and are also naturally occurring radionuclides. Ra-226 was detected at concentrations that were representative of normal background level fluctuations. Ra-226 was found at concentrations of 1.69 pCi/g (dry) to 1.86 pCi/g. (dry) at the indicator locations and 0.98 pCi/g (dry) to 1.17 pCi/g (dry) at the control location.

AcTh-228 was found at the indicator location and ranged from 0.59 pCi/g (dry) to 0.84 pCi/g (dry) and 0.34 pCi/g (dry) to 0.52 pCi/g (dry) at the control location. Be-7 was not detected in any of the indicator or control samples. Be-7 is a naturally occurring radionuclide and has been detected intermittently during the past.

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

Evaluation of average historical data (1979-1987) shows that Cs-137 has ranged from 0.05 pCi/g (dry) in 1982 to 0.22 pCi/g (dry) in 1979 at the control location. Cs-137 at the Nine Mile Point indicator location has ranged from 0.11 pCi/g (dry) in 1981 to 1.58 pCi/g (dry) in 1984. For the years, 1985 1988, Cs-137 was not detected. The station's Technical Specifications required shoreline sediment samples to be collected from the closest recreational area where the shoreline was utilized. The indicator sampling location was relocated, therefore, to an area just east of the site boundary. This change was initiated in 1985. As noted above, Cs-137 was not detected during 1985 1988 at the new location.

The evaluation of past Co-60 data indicates that Co-60 has not been detected during the period of 1979 1981 at the Nine Mile

Point indicator location. During 1982, Co-60 was detected at an average concentration of 0.16 pCi/g (dry) at the Nine Mile Point location. Co-60 increased to an average concentration of 0.25 pCi/g (dry) during 1983 and decreased to 0.24 pCi/g (dry) during 1984. As noted above, the indicator location was relocated during 1985 as a result of the Technical Specifications. During the years 1985 1988, Co-60 was not detected at this new location. Co-60 has not been detected at the control location since 1979 which was the beginning of the review period.

Tables 21 and 22 show historical environmental data for shoreline sediment samples. Shoreline sediment samples were not collected prior to 1979.

The impact, as expressed by a dose to man, cannot be evaluated because no plant related gamma emitting radionuclides were detected in the control or required indicator shoreline sediment samples.

A. 2. ~ Table 4A, 4B A total of twenty-seven fish samples were analyzed as a result of collections in the spring season (May 1988) and in the fall season .(September-October 1988). Collections were made utilizing 'gill nets 'at one location greater than five miles from the site (Oswego Harbor area), and at two locations in the vicinity of the lake discharges for the Nine Mile Point Unit Nl (02), and the James A. FitzPatrick (03) generating facilities.

The Oswego Harbor samples served as control samples while the NMP (02) and JAF (03) samples served as indicator samples.

Samples were analyzed for gamma emitters. Table 4A shows results in units of pCi/g (wet) for purposes of data evaluation. Table 4B shows, results in units of pCi/kg (wet), as required by the Technical Specifications.

Spring fish collections were comprised of six separate species.

The six species represented three feeding type. Lake trout, brown trout, Chinook salmon, and white perch are highly predacious and feed on significant quantities of smaller fish such as smelt, alewife, and other smaller predacious species.

Rainbow smelt represent the second feeding type and are characterized by the consumption of small fish species and zooplankton. The third feeding type is represented by white sucker which are bottom feeders that consume bottom dwelling organisms and decaying organic matter.

Cs-137 was detected in six of the ten indicator samples and in four of the five control samples collected during the spring.

Indicator samples showed Cs-137 concentrations to be slightly

A. 2. ~- Table 4A, 4B (Cont'd) greater than control results for some samples and slightiy less than or equal to control results for other samples. The average indicator Cs-137 concentration was slightly less than the average control concentration. The indicator results, however, are not significantly different from the control results and are therefore considered to be representative of background concentrations. The detected Cs-137 concentration in lake trout samples was 0.027 pCi/g (wet) for the indicator samples. The detected Cs-137 concentration in control samples was 0.023 pCi/g (wet) for lake trout. Cs-137 in brown trout samples ranged from 0.022 to 0.023 pCi/g (wet) at the indicator locations. Cs-137 in the control sample was 0.030 pCi,/g (wet) (one sample collected). Chinook salmon. showed Cs-137 detected at 0.030 and 0.031 pCi/g (wet) for the indicator samples and 0.053 pCi/g (wet) for the control sample. White perch samples showed Cs-137 detected only once at 0.030 pCi/g (wet) at the indicator locations and once in the control sample at a concentration of 0.028 pCi/g (wet). Cs-137 was not detected in rainbow smelt at the indicator or control locations. In addition, Cs-137 was not detected in the one white sucker sample collected from the Fitzpatrick location.

K-40 was detected in all of the spring samples collected. K-40 is a naturally occurring radionuclide and is not related to power plant operations. Detectable concentrations of K-40 in the indicator samples ranged from 2.64 to 4.92 pCi/g (wet) and 2.75 to 5.31 pCi/g (wet) for the control samples. Ra-226, also naturally occurring, was found at levels that ranged from 0.17 to 1.03 pCi/g (wet) at the indicator locations and 0.42 to 0.61 pCi/g (wet) at the control location. No other radionuclides were detected in the spring fish samples.

Fall fish sample collections were comprised of four separate species and twelve individual samples. Three samples each of walleye, lake trout, smallmouth bass and white sucker were collected at a combination of two indicator sample locations (NMP and JAF) and one control sample location (Oswego Harbor area). Samples were collected by gill net in September October.

Cs-137 was detected in five of the twelve samples which included the control samples. Indicator samples showed an average Cs-137 concentration that was approximately equal to the control sample mean from the off-site location. The detected concentrations were not significantly different from one another because of the extremely small quantities detected. Cs-137 in walleye samples at the indicator locations was detected once at 0.020 pCi/g (wet) and was not detected at the control location. Lake trout samples showed a Cs-137 concentration of 0.031 pCi/g (wet) for

in smallmouth bass 's-137 samples was detected only once at a concentration of 0.030 pCi/g (wet) at the indicator locations and was not detected at the control location. 'hite sucker samples were available at both indicator and control locations.

Cs-137 was not detected in these samples. The one species of bottom feeder collected during the fall season (white sucker) showed no detectable Cs-137 because of different feeding habits and because this species is not in the same position on the food chain as the other predacious species.

K-40 was detected in all of the fall samples collected.

Detectable concentrations of K-40 in the indicator samples ranged from 3.79 to 4.51 pCi/g (wet) and 4.00 to 4.80 pCi/g (wet) for the control samples. K-40 is naturally occurring.

Ra-226 was also detected and is naturally occurring. Ra-226 ranged from 0.38 to 0.67 pCi/g (wet) for the indicator samples and from 0.42 to 0.76 pCi/g (wet) for the control samples. No other radionuclides were detected in the fall fish samples.

Review of- past environmental data indicates that the mean annual Cs-137 concentration has decreased significantly from the 1976 through 1979 results for indicator samples. Average concentrations for these samples decreased from a level of 1.4 pCi/g (wet) in 1976 to a level of 0.028 pCi/g (wet) in 1986.

Control sample results have also decreased from a level of 1.2 pCi/g (wet) in 1976 to a level of 0.025 pCi/g (wet) in 1986.

Results from 1980 to 1986 have, shown a fairly consistent decreasing trend for control and indicator samples. During 1987 and 1988, control and indicator mean results increased slightly when compared to 1986.

The general decreasing trend for Cs-137 is most probably a result of ecological'ycling. The concentrations of Cs-137 detected since 1976 in fish are a result of weapons testing fallout, and the general down'ward trend in concentrations will continue as a function of ecological cycling and nuclear decay.

There was no apparent effect from the 1986 Chernobyl Nuclear Plant acci'dent during 1986 relative to Cs-137 results in fish samples although an effect may have been detected during 1987 and 1988 since both indicator and control location mean results increased slightly.

Tables 23 and 24 show historical environmental sample data for fish.

Lake Ontario fish are considered an important food source by many. Therefore, fish are an integral part of the human food chain.

A. 2. ~ Table 4A, 4B (Cont'd)

Based on the importance of fish in the local diet, a reasonable conservative estimate of dose to man can be calculated.

Assuming that an adult consumes 21.0 kg of fish per year (Regulatory Guide 1.109 maximum exposed age group) and the fish consumed contains an average Cs-137 concentration of 0.034 pCi/g (wet) (annual mean result of indicator'amples for 1988), the whole body'ose received would be 0.051 mrem per year. The critical organ in this case is the liver which would receive a calculated dose of 0.078 mrem per year. The Cs-137 whole body and critical organ doses are conservative calculated doses associated with consuming fish from the Nine Mile Point area (indicator samples). No radiological decay is assumed for the calculation of doses.

Conservative whole body and critical organ doses can be calculated for the consumption of fish from the control location as well. In this case the consumption rate is assumed to remain the same (21.0 kg per year ) but the average annual Cs-137 concentration for the control samples is 0.033 pCi/g (wet). The calculated Cs-137 whole body dose is 0.049 mrem per year and the associated dose to the liver is 0.076 mrem per year.

In summary, the whole body and critical organ doses observed as a result of consumption of fish is small. .Doses received from the consumption of indicator and control sample fish are approximately the same. The doses from indicator sample fish are slightly greater, although well within natural variability.

For example, the whole body and organ doses from the control samples were greater during 1985. Doses from both sample groups are considered background doses.

A. 3. Tables 5 and 6 Surface water samples were analyzed monthly for gamma emitters (using gamma spectral analysis) during 1988. Tritium analyses were performed quarterly. Quarterly samples (i.e., analysis for tritium) were composite samples.

The analytical results for the 1988 surface water samples showed no evidence of plant related radionuclide buildup in the surface water in the vicinity of the site. Indicator samples were collected from the inlet canal at- the James A. FitzPatrick facility. The control location samples were collected at the inlet canal of Niagara Mohawk's Oswego Steam Station. These two locations are required to be sampled by the Technical Specifications. Tables 5 and 6 show the results of surface water samples analyzed during 1988.

Gamma spectral analysis was performed on twenty four monthly composite samples (two locations) required by the Technical Specifications. In addition, three optional sample locations were evaluated. These included the Nine Mile Point Nuclear Station Unit 1 and Unit 2 inlet canals and the City of Oswego drinking water supply. The drinking water supply composite samples consisted of twice per week grab samples. Only two radionuclides were detected in samples from the five locations over the course of 1988. These radionuclides were naturally occurring.

K-40 was detected intermittently in both Technical Specification required intake canal samples. The James A. FitzPatrick inlet canal samples showed K-40 detected in ten of the twelve monthly samples and ranged from 60 to 248 pCi/liter. K-40 in the Oswego Steam Station inlet canal was detected in ten of the twe'lve samples and ranged from 46 to 232 pCi/liter. The Nine Mile Point Unit 1 inlet canal, Unit 2 inlet canal and the city water samples showed K-40 detected in twelve, twelve and eleven respectively, of the twelve monthly samples for each location.

For these samples, K-40 concentrations ranged from 50 to 244 pCi/liter, from 70 to 265 pCi/liter and from 68 to 267 pCi/liter respectively.

Ra-226 was detected intermittently in samples from all five locations. Ra-226 was detected in twelve of the twelve monthly samples from the Nine Mile Point Unit 81 inlet. canal and ranged from 59 to 144 pCi/liter. The Nine Mile Point Unit 2 inlet canal showed Ra-226 detected in ten of the twelve samples and ranged from 73 to 143 pCi/liter. Samples from the FitzPatrick location showed Ra-226 in ten of the twelve monthly samples and ranged from 73 to 124 pCi/liter. The control sample location (Oswego Steam Station) showed Ra-226 in nine of the twelve monthly samples and ranged in conce'ntrations from 63 to 130 pCi/liter. The city water samples results showed Ra-226 detected in ten of the twelve monthly'samples and ranged from 80 to 118 pCi/liter.

Tritium samples are quarterly samples that are a composite of the appropriate calendar months. Tritium was detected in samples taken at all five locations. Two of the sample results showed that tritium was not detected within the analytical sensitivity of the analysis. The City of Oswego drinking water showed tritium concentrations ranging from 180 to 370 pCi/liter with a mean of 292 pCi/liter. Tritium concentrations for the James A. FitzPatrick inlet canal ranged from 430 to 480 pCi/liter and showed a mean concentration of 460 pCi/liter.

Inlet'anal samples taken at Nine Mile Point Unit 1 'and Unit 2 showed tritium concentrations ranging from 280 to 750 pCi/liter

D (Cont'd) t r Tables 5 and 6 (Cont'd) and 210 to 420 pCi/liter respectively. The annual mean concentration was 462 pCi/liter and 320 pCi/liter respectively.

The Technical Specification control location (Oswego Steam Station inlet canal) showed tritium results which ranged from 240 to 460 pCi/liter with a mean of 320 pCi/liter.

As noted above, annual tritium results for the Nine Mile Point Unit 1 inlet canal ranged from 280 to 750 pCi/liter. The maximum result (750 pCi/liter) was greater than the control location results (Oswego Steam Station) which ranged from 240 to 460 pCi/liter or the drinking water samples which ranged from 180 to 370 pCi/liter. The maximum result of 750p120 pCi/liter occurred during the second quarter. The third quarter showed a result of 530p100 pCi/liter and the fourth quarter was 290~70.

The second and third quarter results were above background levels. The fourth quarter result'ppeared to be in general agreement with the control sample fourth quarter. result.

During 1988, the Unit 1 facility was not operational and there were no liquid discharges from the facility. There are no known operational events during the second and third quarters of the year which would have contributed to the increase in tritium levels over normal background levels other than the recirculation of the 'irculating water. During this time period, the main circulating water pumps were not operational.

A major portion of the discharge flow resulting from the service water system. was recirculated from the .discharge canal to the inlet canal in order to prevent ice from forming in the inlet canal during January through March. The recirculation was

'aintained during the second quarter and part of the 'third quarter of the year. Any small sources of tritium that may have entered the discharge canal via the service water system would have a tendency to increase in the water being recirculated.

Samples obtained at the NMP-1 inlet sample location would be representative of recirculated water. Although tritium was detected in the NMP-1 inlet canal samples for the second and third calendar quarters, other fission product radionuclides, such as Cs-137 or Co-60, were not detected. Samples of the NMP-1 service water system effluent will be taken in order to determine whether any minor leakage is occurring.

Review of past environmental data for Cs-137 from 1979 through 1987 shows that this radionuclide was detected only once at the control location during 1979 at a concentration of 2.5 pCi/liter. Cs-137 at the indicator location (JAF inlet canal) was detected only once during 1982 at a concentration of 0.43 pCi/liter. The 1979 control sample result is . suspect and may have been a result of contamination during handling or instrument background since Cs-137 was not detected in the indicator inlet canal.

location (JAF inlet canal) during 1982 was detected in a January composite sample and may have been a result of inlet canal tempering (the addition of discharge water to the inlet canal) or instrument background. Cs-137 was not detected during 1988 in surface water samples.

Other plant'elated radionuclides detected during a review period of 1979 1987 include only Co-60. The control sample location results showed that Co-60 was detected 'once in 1981 (the May composite sample). This result is suspect and, as noted above, may be a result of contamination during handling or may be instrument background. This result was 1.4 pCi/liter.

Results from the indicator location showed that Co-60 was detected three times during 1982 and averaged 1 9 pCi/liter. ~

These positive results were attributed to inlet canal tempering

'and instrument background. Co-60 was not detected during 1988 in surface water samples.

Tables 25 and 26 show historical environmental sample data for surface water.

Previous annual mean results for tritium at the indicator sample location (FitzPatrick inlet canal) has decreased since 1976.

Mean sample results reviewed from 1976 through 1987 showed a peak average value of 627 pCi/liter (1976) and a minimum value of'27 pCi/liter (1980). The annual mean tritium result at the indicator location for 1988 was 460 pCi/liter.

Mean tritium results for the control location (Oswego Steam Station) can not be evaluated with regard to long term historical data since sampling was only initiated at this location in 1985. Some idea of the variability of control sample data can be obtained, however, by review of previous data from the City of Oswego drinking water samples. The drinking water samples are not likely to be affected by the station because of the effects of the distance, lake currents, and the discharge of the Oswego River. Therefore, this previous sample data represents acceptable control sample data for evaluation purposes.

Historical mean annual tritium results from previous city water samples (1976-1984) and Oswego Steam Station samples (1985-1987) show that the tritium concentrations have decreased. The maximum annual average was found in 1976 (652 pCi/liter) and the minimum in 1982 (165 pCi/liter). Mean annual results from 1979 to 1987 have remained relatively consistent. The annual mean result for 1988 was 320 pCi/liter.

The impact, as expressed as a dose to man, can not be evaluated because plant related gamma emitting radionuclides were not detected in monthly surface water samples. Plant related radionuclides were not found in the optional drinking water samples either. Although tritium was found at slightly elevated levels during the second and third quarters of the year at the NMP-1 inlet canal, the levels noted in the drinking water samples were normal and representative of background levels.

For the purposes of illustration, the impact, expressed as a dose to man, can be determined by assuming the inlet water for the two calendar quarters flows from the site to the nearest drinking water inlet and is subsequently ingested. Several assumptions must be made for this determination. These include: the nearest drinking water source is at the City of Oswego, the dilution of the'ater that flows to the source is 7.7 (NNP-1 Appendix I submittal), the average tritium concentration during the two calendar quarters minus the associated average background concentration is 265 pCilliter, the maximum exposed individual is an infant and the consumption rate is 330 liters per year or 82.5 liters per calendar quarter (Regulatory ,Guide 1.109). The theoretical dose as a result of ingesting water originating from the inlet canal is 0.0017 mrem to the whole body and any organ. This dose can be compared to the whole body dose received from naturally occurring cosmic radiation originating from outer space when one'ncreases in altitude. A whole body dose of 0.0017 mrem is equal to residing at a location 328 feet higher in altitude for approximately 7.5 hours5.787037e-5 days 0.00139 hours 8.267196e-6 weeks 1.9025e-6 months .

Concentration in pCi/m3

- Locations required by the Technical Specifications The observed small increases and decreases in general gross beta activity can be attributed to changes in 'he environment, especially seasonal changes. The concentration of naturally

..occurring radionuclides in the lower limits of the atmosphere directly above land areas are affected by processes such as wind direction, snow cover, soil temperature and soil moisture content. Little change wa's noted in gross beta activity which corresponded with weapons testing as has been observed in past years. Review of air particulate gross beta concentrations shows that no significant increases in concentration occurred during 1988.

In general, the trend in air particulate gross beta activity has been one of decreasing activity since 1977 (extent of the review period). The mean gross beta concentration at control'ocations has decreased from a level of 0.165 pCi/m3 in 1981 to 0.021 in 1987. Results from indicator air sampling locations ranged from 0.151 pCi/m3 in 1981 'o 0.021 pCi/m3 in 1987. For both indicator locations and control locations, the gross beta concentration during 1977 to 1987 fluctuated with the detonation of thermonuclear weapons. The Technical Specification control and indicator results during 1988 were 0.018 pCi/m3 and 0.018 pCi/m3 respectively which represented the lowest level recorded to date.

The results of all monthly composite samples are included on Table 9.

The results for the monthly composite samples showed positive results for Be-7, K-40, and Ra-226. All three of these radionuclides are naturally occurring. Be-7 was found in all of the monthly composite samples from all locations required by the Technical Specifications. Be-7 ranged from 0.055 to 0.153 pCi/m3 for the Technical Specification indicator locations (R-l, R-2, R-3, and R-4).

The 1983 control mean Co-60 concentration was also 0.0007 pCi/m3 which was slightly greater than 1982 control results. As noted in, previous annual reports, however, a portion of the Co-60 detected during 1983 was attributed to contamination during handling of the unused filters prior to installation. Co-60 was detected during the first quarter of 1984 and averaged 0.0008 pCi/m3 at the control stations and 0.0012 pCi/m3 at the indicator stations. However, the 1984 Co-60 positive results were a result of contamination during handling and not a result of operations at the site.

~

The general reduction in previous indicator and control Co-60 concentrations (1981 1983) was a result of nuclear decay and ecological cycling of Co-60 initially produced by the 1980 Chinese weapons test. Co-60 was not detected during 1985 1986 in air particulate samples from either indicator or control locations. During 1987, Co-60 was detected once at a concentration of 0.0017 pCi/m3 at an optional air monitoring station. However, "the Co-60 detected during 1987 was a result of contamination from improper handling of the sample, and not as a result of effluents from the site. This evaluation is contained in the 1987 annual report. Results from 1988 showed that Co-60 was not detected from either control or indicator sample locations.

Historically, Cs-137 has been variable during the past and has been present in air particulate samples since 1977. During 1977, both indicator and control Cs-137 average concentrations were approximately equal and averaged 0.0038 pCi/m3. Cs-137 average concentrations at indicator and control locations decreased during 1978 and 1979 to 0.0017 and 0.0013 pCi/m3 respectively. Average concentrations during 1980 and 1981 were approximately equal at control and indicator locations. Cs-137 during 1980 was approximately equal to 1979 and increased slightly in 1981 from 1979. The 1980 and 1981 average

B. 2. 't Table 9 (Cont'd) concentrations were 0.0014 and 0.0016 pCi/m3 respectively. The mean 1982 concentration for Cs-137 decreased to 0.0004 pCi/m3. The 1983 mean Cs-137 concentration for the indicator and control composite samples were 0.0002 and 0.0002 pCi/m3 which was a reduction from 1982 results. Cs-137 was not detected during 1984 in any of the indicator or control air particulate composite samples. As noted above for the average annual "Co-60 results, the reduction in Cs-137 results since 1981 is attributed to nuclear decay and ecological cycling of Cs-137 initially produced by the 1980 Chinese weapons test. Cs-137 was not detected during 1985 in air particulate samples. Cs-137 was detected during 1986 as a result of the Chernobyl Nuclear Plant accident in April 1986. Mean Cs-137 concentrations for vindicator and control sample locations were 0.0183 and 0.0193 pCi/m3 respectively. During 1987 and 1988, Cs-137 was not detected.

Prior to 1984, several radionuclides were detected that were associated with the 1980 Chinese weapons test and other weapons tests prior to 1980. These radionuclides were not detected during 1984 or 1985 as a result of nuclear decay and ecological cycling. These include Zr-95, Ce-141, Nb-95, Ce-144, Mn-54, Ru-103, Ru-106 and Ba-140. In addition, La-140 was detected once during 1983 and 'infrequently during 1978 and 1981. La-140 was not detected during 1984 or 1985. During 1986, however, several fission product radionuclides were detected that were a result of the Chernobyl Nuclear Plant accident. These included Cs-134, Cs-137, Nb-95, Ru-103, Ru-106, La-140 and I-131. All of these, with the exception of Cs-134 and particulate I-131, were detected subsequent to the 1980 Chinese weapons test (1981 1983). These radionuclides were not detected during 1984 1985. The concentrations detected during 1986 as a result of the Chernobyl accident were generally greater than the concentrations detected as a result of the 1980 Chinese weapons test. The presence of the radionuclides from the Chernobyl facility, however, extended over a very brief period (two months) while many of the radionuclides from the 1980 Chinese weapons test were present for approximately two years. During 1987 and 1988, none of the radionuclides associated with the 1986 Chernobyl accident were detected in air particulate samples.

Tables 31 and 32 show historical environmental sample data for air particulate composites.

B. 3. Tables 10 and 11 During the 1988 sampling program, airborne radioiodine was not found in any of the fifty-two weekly samples from the control location required by the Technical Specifications. LLD values at the control location ranged from 0.005 0.012 pCi/m3.

I-131 has been detected in the past at control locations.

During 1976, the mean off-site I-131 concentration was 0.60 pCi/m~. The,.1977 mean I-131 concentration decreased to 0.32 pCi/m3 and for 1978 the concentration decreased by a factor of ten to 0.03 pCi/m3. During 1979 1981 and 1983 1985, I-131 was not detected. I-131 was detected once during 1982 at a concentration of 0.039 pCi/m3. Results from 1986 showed that I-131 was detected at the control location. This was a result of the 1986 Chernobyl Nuclear Plant accident. The I-131 mean result was 0.151 pCi/m3. I-131 was not detected, at the control location during 1987 or 1988.

During 1988, the indicator locations required by the Technical Specifications (approximate site "boundary locations) showed no detectable levels of I-131. LLD values for I-131 ranged from 0.005 0.019 pCi/m3.

During 1988, I-131 was detected at one of the optional on-site monitoring locations that was not required by the Technical Specifications. The H on-site location is in close proximity to the generating facilities and is located in the northeastern area of the site. A detectable quantity of 0.012~0.007 pCi/m3 was found at the H on-site monitoring location during the week of June 6-13, 1988. I-131 was not detected at any of the other optional air monitoring locations during the aweek of June 6-13 nor was it detected at any other time dpring 1988.

I-131 at indicator locations has been detected in the past and was detected at a mean concentration of 0.33 and 0.31 pCi/m3 during 1976 and 1977. The average concentration decreased to 0.04 pCi/m3 during 1978 and was not detected during 1979. The 1980-1982 average concentrations were 0.013, '0.029, and which were reductions in view of previous I-131 O.OL6'Ci/m3 concentrations. During 1983, the mean I-,131 concentration was 0.028 pCi/m3 which represented a slight increase compared to 1982. For the most part, I-131 in indicator and control samples was a result of I-131 from weapons testing. A small portion of the concentrations detected may have been a result of operations at the site. The concentrations detected during 1983 at the on-site sample stations were a result of operations at the site. I-131 was not detected in any of the 1984 or 1985 samples. During 1986, I-131 was detected at the indicator locations at a mean concentration of 0.119 pCi/m3 as a result of the Chernobyl Nuclear Plant accident. I-131 was found at a mean concentration of 0.014 pCi/m3 during 1987 and was a result of operations at the site. As noted previously, 'I-131 was not found at the Technical Specification required indicator locations during 1988.

n The impact of the measurable concentration of I-131 at the optional indicator location can be assessed by projecting a dose to the maximum exposed organ (thyroid) and the whole body as a result of inhalation. The maximum exposed age group is the child. Using Standard Regulatory Guide 1.109 methodology, an inhalation rate of 3700 m~ per year and the indicator location I-131 concentration, conservative doses can be calculated. In order to be conservative and to simplify the computations, no radiological decay is assumed and the maximum exposed individual is assumed to remain at the location for one week. Maximum child thyroid and whole body doses are presented below.

These doses are very small and are of no significance especially when one considers the fac't that the monitoring location is not an area occupied by members of the public.

B. 4. Table 12 TLD's were collected and read once pe'r quarter during the 1988 sample year. The TLD results are, for the most part, an average of eight independent readings at each location and are reported in mrem per standard month (Table 12A) and in mrem per quarterly period (Table 12B).

TLD's required by the Technical Specifications include two TLD's at each location with four independent readings per TLD.

TLD results included on Tables 12A and 12B are comprised of TLD's required by the Technical Specifications and special interest TLD's not required by the Technical Specifications.

During 1988, TLD's were collected on approximately March 30, 1988, June 29, 1988, September 29, 1988 and December 29, 1988.

Overall TLD results are evaluated by organizing environmental TLD's into five different groups. These groups include: (1) on-site TLD's (TLD's within the site boundary not required by the Technical Specifications), (2) site boundary TLD's (one in each of the sixteen 22 1/2 degree meteorological sectors), (3) a

B. 4. D E v'm t m t Table 12 (Cont'd) ring of TLD's four to five miles from the site in each of the land, based 22 1/2 degree meteorological sectors, (4) special interest TLD's in areas of high population density, and (5) control TLD's in areas beyond any significant influence of the generating facilities. Special interest TLD's are located at or near large. industrial sites, schools, or proximal towns or communities. Control TLD's are located to the southwest, south, south-southeast, and northeast of the site at distances of 12.6 to 26.4 miles from the site.

Most of the TLDs required by the Technical Specifications during 1988 were initiated in 1985 as a result of the issue of new Technical Specifications by the NRC. Therefore, these TLDs can only be compared to 1985 1987 results. Other TLDs, which

-include a few TLDs required by the Technical Specifications (i.e., numbers 7, 14, 15, 18, 23, 49, 56, and 58) and other optional TLDs, can be compared to results prior to 1985 since these TLDs were established prior to 1985.

On-site TLD's are TLD's at special interest areas and, with the exception of TLD numbers 7 and 23, are not required by the Technical Specifications. These are located near the generating facilities and at previous or existing on-site air sapling stations. TLD's located at the air sampling stations include, numbers 3, 4, 5, 6, 7, 23, 24, 25 and 26. The results for these TLD's are generally consistent with, previous years results although a. slight increase was. noted when compared to 1987.

These results ranged from 4.4 to 11.9 mrem per standard month.

TLD 83 is located in the vicinity of Nine Mile Point Unit 2 and is between the Unit 1 facility and the FitzPatrick facility.

The results for TLD N3 were approximately double the results of the other TLD's during the first three quarters of 1988 because

- of the effects from the Unit 2 and the FitzPatrick facility.

Overall, slight increases were noted during the third quarter of 1988 for these TLD's, as well as other groups of TLD's, including the control group.

Other on-site TLD's include special interest TLD's located near the north shoreline of the Unit 1, Unit 2 and FitzPatrick facilities, but in close proximity to radwaste facilities and the Unit 1 reactor building. These TLD's include numbers 27, 28, 29, 30, 31, 39, and 47. Results for these TLD's during 1988 were variable and ranged from 6.8 to 40.4 mrem per standard month as a result of activities at the radwaste facilities and the operating modes of the generating facilities. Results for 1988 are consistent with the ranges of variability noted in 1987 for TLD's at or near these locations. TLD's in this group ranged up to approximately seven times control TLD results.

Additional on-site TLD's are located near the on-site Energy

Center and the associated northeast shoreline. These TLD's include numbers 18, 103, 106 and 107. TLD's numbered 103, 106 and 107 are located to the east of the Energy Center and to the west of the Unit 1 facility. TLD number 18 is located on the west side of the Energy Center. Results during 1988 showed these TLD's ranged from 4.6 7.2 mrem per standard month and were slightly greater than the 1987 results. Again, slight increases were noted in the third quarter results as was noted for all TLD's, including control TLD's.

Site boundary TLD's are required by the Technical Specifications and are located in the approximate area of the site boundary with one in each of the sixteen 22 1/2 degree meteorological sectors. These TLD's include numbers 75, 76, 77, 23, 78, 79, 80, 81, 82, 83, 84, 7, 18, 85, 86 and 87. TLD numbers 78, 79, 80, 81, 82, 83, 84, 7 and 18 showed results that were consistent with control TLD results and ranged from 3.4 to 7.0 mrem per standard month. Site boundary TLD's during 1988 were consistent with 1985-1987 results.. TLD numbers 75, 76, 77, 23, 85, 86, and 87 showed results that ranged up to three times the results of control TLD's. These results ranged from 5.2 to 17.9 mrem per standard month. This latter group of TLD's are located near the lake shoreline (approximately 100 feet from the shoreline), but are also located in close proximity of the reactor building and radwaste facilities of Unit 1 and Unit 2 and the radwaste facilities of the FitzPatrick facility.

A net site boundary dose can be estimated from available TLD results and control TLD results. TLD results from TLD's located near the site boundary in sectors facing the land occupied by members of the public (excluding TLD's near the generating facilities and facing Lake Ontario) are compared to control TLD results. The site boundary TLD's include numbers 78, 79, 80, 81, 82, 83, 84, 7 and 18. Control TLD's include numbers 8, 14, 49, 110 and ill. Net'ite boundary doses for each quarter in are as follows:

The third group of environmental TLD's are those TLD's located four to five miles from the site in each of the land based 22.5 degree meteorological sectors. These TLDs are required by the Technical Specifications. At this distance, TLD's are not present in eight of the sixteen meteorological sectors that are located over Lake Ontario.

Results for this group of TLD's during 1988 fluctuated slightly as a result of changing naturally occurring conditions and the different concentrations of naturally occurring radionuclides in the ground at each of the locations. These TLD's were established in 1985 and include numbers 88, 89, 90, 91, 92, 93,,

94 and 95. Results fluctuated from 3.8 to 7.0 mrem per,standard month. These results are generally consistent with control TLD results during '1988. Results 'or this group of TLDs were consistent with the 1985 1987 results. Results were also consistent with other 'ff-site TLD results 'during 1988 and previous to 1988. Again, third quarter TLD results were slightly elevated along with all other groups of TLD's, including control groups.

The fourth group of envir'onmental TLD's are those TLD's located near the site boundary and at special interest areas such as industrial sites, schools, nearby communities, towns, off-site air sampling stations, the closest residence to the site, and the off-site environmental laboratory. Many of these TLDs are required by the Technical Specifications. Others are optional.

This group of TLD's include numbers 9, 10, ll, 12, 13, 15, 19, 51, 52, 53, 54, 55, 56, 58, 96, 97, 98, 99 100, 101, 102, 108

, and 109. TLD numbers 108 and 109 are new TLD locations that were established during 1988 and were added to assist in the evaluation of the critical residence. Results ranged from 3.9

'o 7.2 mrem per standard month. All the TLD results from this group were within the general variation noted for the control TLD's. Results during 1988 for TLD's established during previous years were consistent with results noted for those years. Overall, third quarter TLD results for this group were slightly elevated as were other TLD groups, including the control group.

The fifth group of TLD's include those TLD's considered as control TLD's. These TLD's are required by the Technical Specifications and include numbers 14 and 49. Optional control locations are TLD numbers 8, 110, and 111. TLD numbers 110 and 111 were added to the program during 1988 to expand the data

B. 4. v t ' Table 12 (Cont'd) base for control TLD's. Results for 1988 ranged from 4.4 to 6.8 mrem per standard month. Results from 1988 were consistent with previous years results. However, an annual average increase was noted in 1986. This increase may have been a result of the Chernobyl Nuclear Plant accident and was not noted during 1987 or 1988. Control TLD's results in 1988 (third quarter) were slightly elevated as were other TLD groups.

Review of past TLD results zgquj. 4~n groups. These groups include site boundary TLDs in each meteorological sector (16 TLDs total), TLDs located off-site in each land based sector at a distance of 4 to 5 miles (8 TLDs total), TLDs located at special interest areas (6 TLDs total) and TLDs located at control locations (2 TLDs total). As noted previously, since the present Technical Specifications became effective in 1985, these TLDs, for the most part, can only be .

evaluated for 1985 1988.

TLDs located at the site boundary averaged 6.2 mrem per standard month during 1985. During 1986 and 1987, site boundary TLDs averaged 7.0 and 6.1 mrem per standard month. As noted previously, this group of TLDs can fluctuate because several of these TLDs are located in close proximity to the generating facilities; An increase was noted during 1986 although such an increase was noted for all TLDs including control TLDs. During 1988, site boundary TLDs averaged 6.4 mrem per standard month.

This result is slightly greater than 1987 results, and is due to the increased results noted in the third quarter.

TLDs located off-site at a distance of 4 to 5 miles from the site in each of the land based meteorological sectors averaged 5.0 mrem during 1985. During 1986 1987 off-site sector TLDs averaged 6.0 mrem and 5.2 mrem per standard month. The 1986 results demonstrated an increase for this group of TLDs.

Results for 1988 for the group averaged 5.3 mrem per standard month. This is fairly consistent with previous years results.

Again, 1988 third quarter TLD's, showed a slight increases.

Special interest TLDs are located at areas of high population density, such as major work sites, communities, schools, etc.

and at residences near the site (critical receptor areas). This group of TLDs averaged 5.3 mrem per standard month during 1985.

During 1986, this same group of TLDs averaged 6.1 mrem. The 1987 results showed a decrease when compared to the 1985 and 1986 results and averaged 5.1 mrem per standard month. 1988 results averaged 5.3 mrem per standard month. This result is consistent with previous years results. Third quarter 1988 TLD's showed an increase.

The final group of TLDs required by the Technical Specifications is the control'roup. This group utilizes two TLD locations positioned well beyond the site. Results from 1985 for the control group averaged 5.4 mrem per standard month. During 1986, this same group of TLDs averaged 6.3 mrem per standard month. A marked increase was noted in the second quarter of 1986. The increase may have been a result of the Chernobyl Nuclear Plant accident. Results for 1987 averaged 5.2 mrem" per standard month. Results for 1988 averaged 5.4 mrem per standard month and showed levels typical of 1985 and 1987. Slight increases were noted in third quarter results.

During 1988, all environmental TLD groups required by the Technical Specifications were'onsistent with results observed in 1987. However, all Technical Specification TLD's showed a slight increase during the third quarter of 1988. This increase was noted for other non-technical specification TLD's, as well as all control TLD's. The only TLD's in which the third quarter increase was not noted were the TLD's located along the north fence near the generating facilities. These TLD's reflect the activities conducted at the radwaste facilities and the operating modes of the generating facilities. Due to the variability of the activities conducted during 1988, the third quarter increases noted for other groups of TLD's were masked by already increased TLD results.

Third quarter 1988 increases in all groups of TLD's ranged'rom 22-40K when 'ompared to the second quarter. No other environmental parameter or pathway measured revealed any increase or abnormalities during the period. Additionally, control TLD's located beyond the influence of the plant were similarly affected. These two facts exclude the possibility of an undetected radiological occurrence from the, facilities.

Subsequent investigation into the methodology employed by the contractor reading the TLD's revealed that the methodology used in subtracting the TLD transit dose from the gross readings resulted in data that was slightly biased in a conservative manner. Action was initiated to .preclude such an occurrence in the future.

Tables 35 and 36 show the historical environmental sample data for environmental TLD's.

Overall, environmental TLD results for 1988 showed no significant impact from ~

B. 5 Kiik-Tables 13 and 14 Milk samples were collected from a total of six indicator locations (within 10 miles of the site) and one control location (beyond 10 miles from the site) during 1988. . The Technical Specifications require that three locations be sampled for milk within 5.0 miles of the site. During 1988, there were no milk sample locations within 5.0 miles'f the site. The locations that were sampled during 1988 are located from 5.5 to 9.5 miles from the site. The only sample location required by the Technical Specifications during 1988 was the control location which was located 17.0 miles to the southwest of the site (location 865). Sample location descriptions for all milk sample locations utilized during 1988 are listed below.

" and the .second half of each month. Samples were collected during the months of April through December 1988. Since I-131 was not detected during November and December of 1987, no additional samples were collected in January through March of 1988. For each sample, analyses were performed for gamma emitters (analysis by GeLi detector) and for I-131 using a resin extraction. Sample analysis results for gamma emitters are found on Table 13 and for I-131 on Table 14.

Gamma spectral analyses of the bimonthly samples showed K-40, Ra-226 and AcTh-228 to be the only naturally occurring radionuclides detected in the milk samples collected during 1988. K-40 was detected in every sample analyzed and ranged in concentration from 513 pCi/liter to 1,730 pCi/liter at the indicator locations and 1,360 pCi/liter to 1,710 pCi/liter at the control location. Ra-226 ranged from 71 to 258 pCi/liter at the indicator locations and 144 to 231 pCi/liter at the control location. Ra-226 occurred intermittently in milk samples.

AcTh-228 was found on three occasions for milk samples collected from the indicator locations. Detectable levels ranged from 6.7 to 26.7 pCi/liter. AcTh-228 was not detected in the control samples. K-40, Ra-226 and AcTh-228 are naturally occurring radionuclides and are found in many of the environmental media sampled.

Cs-137 was detected once in the 1988 milk samples. The concentration detected was 10.0 pCi/liter and was obtained from location N16 on April 18, 1988. Cs-137 was not detected in any of the other bimonthly samples from this location, nor was it detected in any of the other milk samples from other sample locations. Location 816 is 5.9 miles from the site in a southerly (190') direction.

A concentration of 10.0 pCi/liter is not significant and is slightly above the detectable range of the analytical instrumentation. The source of the detected Cs-137 is thought to be from silage harvested from 1987 or possibly 1986.

Questionnaires, relative to monthly pasturing and supplementary diets of commercial grain and local silage, showed that milk animals had a diet of approximately 90K silage and 10K grain during the month of April 1988 at location 816. Pasture grass was not part of the milk animal diet at location 816 during April 1988. Monthly questionnaires showed that this was the case at the other sample locations except for location 855 where pasture grass accounted for approximately 5X of the milk ,

animal's diet. The monthly questionnaire also noted that a portion of the silage given to milk animals during April 1988 may have been harvested during 1986.

Silage harvested locally during 1986 contained traces of Cs-137 from the April 1986 Chernobyl Nuclear Plant accident. It is thought that the detected quantity of Cs-137 resulted from stored silage because milk animals were not on pasture during April 1988 and because the monthly questionnaire showed that silage originating from 1986 may have been fed to milk animals during April 1988. A similar occurrence was noted in 1987.

Cs-137 was detected on May 4, 1987 at levels of 5.5 pCi/liter and 8.1 pCi/liter. Monthly questionnaires from April 22 and May 4, 1987 showed that milk animals were not on pasture during April through May 4 and that silage constituted a major portion of the milk animal diet. It was also noted during 1987, that Cs'-137 was detected in milk samples at other nuclear sites on the East Coast during the first half of 1987. Cs-137 in these instances was attributable to silage containing trace amounts of Cs-137 from the 1986 Chernobyl Nuclear Plant accident.

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

Milk samples were collected and analyzed twice per month for I-131. I-131 was not detected during 1988 in any of the indicator or control samples. All 1988 I-131 milk sample results are reported as the lower limit of detection (LLD). The LLD results for 1988 milk samples ranged from <0.1 pCi/liter to

<0.5 pCi/liter.

Evaluation of site historical milk data shows that Cs-137 has been detected in environmental milk samples at both indicator (within 10 miles) and control locations (beyond 10 miles). Mean Cs-137 concentrations for 1976 1981 remained fairly consistent and ranged from 8.1 (1980) to 17.1 pCi/liter (1977) at the indicator locations. The 1982 indicator mean was 5.7 pCi/liter which showed a decrease when compared to 1976 1981. Cs-137 in milk during 1983 yielded a mean of 7.2 pCi/liter which was slightly greater than the 1982 mean but was less than the 1976 1981 mean range. During 1983, however, Cs-137 was detected in only 3 of the 66 samples, while in 1982, Cs-137 was detected in 10 of the 54 samples analyzed. Cs-137 was not detected during 1984 or 1985 in indicator milk samples. Results from 1986 showed a mean Cs-137 concentration of 8.6 pCi/liter at the indicator locations. Cs-137 in 1986 milk samples was a result of the 1986 Chernobyl Nuclear Plant accident. During 1987, Cs-137 was found in two indicator samples only at a mean concentration of 6.8 pCi/liter and was also a result of the Chernobyl accident. The 1988 results showed Cs-137 was detected only once at a concentration of 10.0 pCi/liter.

At the control location, Cs-137 has remained fairly consistent for all years from 1978 1982 except for 1979 and 1982. For these years, this radionuclide was not detected. Control samples were not obtained prior to 1978. Cs-137 ranged from 3.9 5.8 pCi/liter during 1978 1981. Cs-137 was not detected at the control location during 1982, 1983, 1984, or 1985. The absence of Cs-137 during 1982 through 1985 may be a result of a two to five year time interval since the last weapons test.

Results from 1986 showed a mean Cs-137 c'oncentration of 8.4 pCi/liter at the control location. The positive Cs-137 results during 1986 were a result of the Chernobyl Nuclear Plant accident. Cs-137 was not detected during 1987 or 1988 at the control location.

Cs-137 in milk samples is, for the most part, a result of previous weapons testing and more recently, the Chernobyl accident. The continuing reduction of Cs-137 levels is a result of nuclear decay and ecological cycling.

An evaluation of historical data for I-131 in milk samples shows that annual mean results ranged from 0.19 pCi/liter to 6.88 pCi/liter at the indicator locations during 1976 1978. I-131 during these years is a result of intermittent weapons testing.

During 1979 1985, I-131 in milk samples at the indicator locations was not detected except during 1980. The mean result during 1980 was 3.8 pCi/liter and was a result of the 1980 Chinese Weapons Test. Results from 1986 showed that I-131 was detected at a mean concentration of 5.2 pCi/liter as a result of the Chernobyl accident. I-131 was not detected during 1987 or 1988 in milk samples.

B. 5 k-Tables 13 and 14 (Cont'd)

Historical data for I-131 from the control location showed that I-131 was detected during 1980 at a .mean concentration of 1.4 pCi/liter. There was no detectable I-131 during the period of 1978 1985 with the exception of 1980. During 1986, I-131 from the control location showed a mean concentration of 13.6 pCi/liter as a result of the Chernobyl accident. I-131 was not detected during 1987 or 1988 at the control location.

Tables 37 and 38 show the historical environmental sample data for milk.

h The impact as a result of Cs-137 in 1988 milk samples can be assessed by calculating conservative doses to man from the consumption of milk with detectable quantities of Cs-137. In order to calculate doses, several assumptions are made. These include: a Cs-137 concentration of 10.0 pCi/liter'or the indicator sample result, a consumption rate of 330 liters (87 gallons) per year for an infant (the maximum exposed individual), an applicable time period of 1 month of the year (Cs-137 was not detected consistently throughout the year) and no radiological decay. Dose factors are taken from Table E-14 of Regulatory Guide 1.109.

The infant whole body dose is calculated as 0.012 mrem. The infant critical organ is the, liver. The dose to the liver is 0.168 mrem. These doses are from consuming milk from the indicator location.

The maximum organ dose is the liver of an infant. The maximum whole body dose, however, is to an adult. Using the same criteria as above, except for a new consumption rate of 310 liters (80 gallons) per year for an adult, th'e maximum exposed organ (liver) dose to an adult is 0.028 mrem for indicator samples. The adult whole body dose is 0.018 mrem. The adult liver dose is less than the infant dose. The adult whole body dose is greater than the infant whole body dose.

For the purpose of illustration, the significance of the above doses can be brought into perspective by comparison to background doses due to the cosmic radiation with changes in altitdde. The whole body dose to an adult is 0.018 mrem as a result of consuming milk from the indicator sample location with detectable Cs-137 during 1988. A,dose of 0.018 mrem is equal to the increase in dose as a result of residing at a location that is 100 meter (328 feet) higher in altitude for 3.3 days. The increase in dose is for a sea level elevation. Because the dose due to cosmic radiation is greater at higher altitudes, a whole body dose from milk consumption of 0.018 mrem is equal to residing in the city of Denver, Colorado for only 3.2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months (NCRP Report No. 45).

An additional comparison can be made to naturally occurring K-40. K-40 has been noted in almost all environmental samples at significant levels. A 70 kilogram adult has an equivalent weight of approximately 154 pounds and contains approximately 0.1 microcuries'f K-40 as a result of normal life functions (inhalation, consumption, etc.). The dose to the bone tissue is about 20 mrem per year as a result of internally deposited K-40 (Eisenbud). For comparison purposes, an adult bone dose can be calculated that results from the consumption of milk with the 1988 concentration of Cs-137. Using the same criteria used for calculating ,the preceding doses, the adult bone dose is 0.020 mrem per year. This calculated dose is small and is only 0.001 of the annual bone dose received from naturally occurring K-40.

The whole body doses calculated from the indicator samples are small. The concentration of Cs-137 in milk detected during 1988 is well below criteria utilized by the Federal Public Health 5ervice and Food and Drug Administration to protect the health and safety of the general population (U. S. Department of Health and Services). The guide used by these federal health agencies for Cs-137 in milk is 240,000 pCi/liter. The maximum Cs-137 concentration observed during the 1988 sampling program was 10.0 pCi/liter. The observed Cs-1'37 concentration is well below the protective action criteria.

Iodine-1'31 was not detected in the bi-monthly milk samples analyzed for 1988. Therefore, no doses to man have been calculated because of the lack of detectable I-131.

B. 6 Tables 15 and 16 In accordance with the Technical Specifications, a land use census was conducted during 1988 to identify within a distance of five miles the location of all milk animals (cows and goats) and the location of the nearest residence in each of the sixteen 22.5 degree meteorological sectors. The milk animal census was actually conducted out to a distance of ten miles in order to provide a more comprehensive census.

The milk animal census is an estimation of the number of cows and goats within an approximate ten mile radius of the Nine Mile Point Site. A census is initiated once per year in the spring.

The census is conducted by sending questionnaires to previous milk animal owners and also by road surveys to locate any possible new owners. In the event questionnaires are not answered, then the owners are contacted by telephone or in person. The local agricultural agency is also contacted.

-36

L A I N (Cont'd) 6 n Tables 15 and 16 (Cont'd)

The number of milk animals located ~w't a the ten mile radius of the site was estimated to be 1193 cows and 15 goats for the '1988 census. The number of cows decreased by 52 and the number of goats decreased by 15 with respect to the 1987 census. No new milk animal locations were noted as a result of the census.

Therefore, there was no change in the milk sampling locations during 1988. Most of the goats found on the census were milking goats. However, any milk produced was utilized by the owners and was not available for the sampling program. 'The results of the milk animal cen'sus are found on Table 15. Milk animal locations are shown on Figure 4.

A residence census was conducted during 1988 to identify the nearest residence in each of the sixteen 22.5 degree meteorological sectors within a distance of fiv'e miles from the site. At this distance, some of the meteorological sectors are over water. These sectors include: N; NNE, NE, ENE, W, WNW, NW, and NNW. There are no residences in these sectors. .The results of'he 1988 residence census showing the applicable sectors and degrees and distance of each of the nearest residences are found on Table 16. The nearest residences are shown in Figure 3.

B. 7 Food product 'amples .collected during 1988 were comprised of garden vegetables, fruit and other types of vegetation. Samples were collected from five indicator locations and one control location. The indicator locations were represented by nearby gardens in areas of highest D/Q (deposition factor) 'values based on historical meteorology and all site release points at operating facilities. The control location was represented by a garden location 9-20 miles distant in a least prevalent wind direction. Garden vegetables were comprised of cabbage, beet greens, squash leaves, lettuce, collard greens and swiss chard which are all considered broadleaf vegetables. Other broadleaf vegetation consisted of pumpkin leaves, bean leaves, pepper leaves and cucumber leaves. In addition, non broadleaf fruits or vegetables were collected. Non broadleaf fruits or vegetables collected in 1988 consisted of tomatoes. At the control location, one sample of each of the same or of a similar type of fruit, vegetable or vegetation was collected. Fruits, vegetables and vegetation were collected in the late summer harvest season.

K-40 was detected in all broadleaf and non-broadleaf vegetables/vegetation. Broadleaf vegetables/vegetation (Swiss chard, beet greens, cabbage, lettuce, pumpkin leaves, bean leaves, cucumber leaves, squash leaves, pepper leaves and

B. 7 collard, greens) showed concentrations of K-40 ranging from 1.39 pCi/g to 7.37 pCi/g (wet). Non-broadleaf fruits (tomatoes) showed concentrations of K-40 ranging from 2.03 pCi/g to 2.76 pCi/g (wet). Be-7 was also found in broadleaf vegetation samples'his radionuclide ranged from 0.09 pCi/g to 3 '4 pCi/g (wet). Non-broadleaf vegetation (tomatoes) showed no detectable.

Be-7. Ra-226 was detected at concentrations that ranged from 0.15 to 0.47 pCi/g (wet) for all sample types at the indicator and control locations. AcTh-228 was also, detected intermittently for all sample types at concentrations that ranged from 0.012 to 0.064 pCi/g'wet) for both indicator and control locations. K-40, Be-7, Ra-226 and AcTh-228 are naturally occurring radionuclides.

Cs-137 was detected in one broadleaf sample (squash leaves) from the indicator locations. The 'detected quantity was at the limit of detection and was 0.008 pCi/g (wet). LLD values for all broadleaf samples ranged from 0.008 pCi/g to 0.017 pCi/g (wet)..

The presence of Cs-137 was not detected in any of the other broadleaf or non-broadleaf samples. It is likely that the quantity of Cs-137 found is a result of uptake by the squash plant or from deposition. The ultimate source of Cs-137 is from weapons testing,. operations at the site or both. Cs-137 .has been detected in soil'amples from areas at the site and at areas well beyond the site as a resul't of past weapons testing.

Cs-137 was not detected at the control location nor was it detected at other indicator locations near the site.

No other radionuclides were detected in the 1988, samples of fruits, vegetables, or other vegetation.

Review of past environmental data indicates that Cs-137 has been detected intermittently during the years of 1976 1987 at the indicator locations and during the years of 1980 1987 at the control locations (control samples were not obtained prior to 1980). Review of indicator sample results from 1976 1987 showed that Cs-137 was not detected during 1976 1978 and 1981 1984 or 1986 1987. During 1979 and 1980, Cs-137 in fruits and/or vegetables showed annual mean concentrations of 0.004 and 0.036 pCi/g (wet) respectively. Cs-137 was found at an indicator location during 1985 at a concentration of 0.047 pCi/g (wet). The detectable concentration was 0.016 pCi/g (wet).

During 1988, Cs-137 was found at a concentration of 0.008 pCi/g (wet). Control sample results during 1980-1987 showed Cs-137 detected only during 1980 at a concentration of 0.02 pCi/g (wet). Cs-137 was not detected at the control location during 1988.

The impact of detectable Cs-137 in food product 'samples can be evaluated by calculating a dose to the maximum exposed individual as a result of consumption. Using standard methodology from NRC Regulatory Guide 1.109, the maximum exposed organ is the bone of a'hild. The maximum whole body dose would be to an adult. The Cs-.137 concentration is 0.008 pCi/g (wet) and is conservatively assumed to be a result of operations at the site and is assumed to remain consistent throughout the year. The consumption rate is assumed to be a maximum consumption rate of 26 kg per year for a child. The calculated doses are 0.07 mrem per year to a child's bone tissue (maximum organ dose) and 0.01 mrem per year to the whole body. The maximum whole body dose, however, occurs to the adult.. Assuming a Regulatory Guide 1.109 maximum consumption rate of 64 kg per year for an adult, the maximum organ dose is 0.06 mrem to the liver and 0.04 mrem to the whole body.

A maximum child organ dose of 0.07 mrem per year and adult whole body dose of 0.04 mrem per year are small when compared to doses from non man-made sources. A maximum organ dose of 0.07 mrem is small when compared to a dose of 20 mrem per year to the gonads and other soft tissues of an adult from, naturally occurring K-40. A maximum whole body dose of 0.04 mrem pe'r year can be compared to the increase in dose from increasing altitude.. As one proceeds from one location to another location higher in altitude, the dose rate will increase slightly as a result of solar radiation. A whole body dose of 0.04 'mrem per year is equivalent to proceeding from one area to another of 100 meters (328 feet) higher in altitude and remaining at that altitude for

= 7.3 days.

An occasion, such as moving to a location 100 meters (328 feet) higher in'ltitude, is a common occurrence. Any dose that may be received as a result of such an occurrence is considered small and insignificant.

C. Qaacluaian The Radiological Environmental Monitoring Program (REMP) was

. established to detect and evaluate any possible impact to the environment surrounding the Nine Mile Point area resulting from operations at the site.

-40

(Cont'd)

Samples representing food sources consumed at higher trophic levels, such as fish and milk, were reviewed closely to evaluate any impact,to the general environment or to man. In addition, the data was reviewed for any possible historical trophic level bioaccumulation trends. Little or no impact could be determined resulting from radionuclide deposition considering all sources (natural, weapons testing, etc..). In regards to doses as a result of man-made radionuclides', a significant portion of the small doses received by a member of the public was from past nuclear weapons testing. Doses as a result of naturally occurring radionuclides, such as K-40, contributed a major portion of the total annual dose to members of the public.

Any possible impact as a result of site operations is extremely minimal when compared to the impact from natural background levels or weapons testing. It has been demonstrated that almost all environmental samples contain traces of radionuclides which

~

are a result of weapons testing or naturally occurring sources (primordial and/or cosmic related). Whole body doses to man as a result of natural sources (naturally occurring radionucli:des in the soil and lower atmosphere) in Oswego County account for approximately 66 mrem per year as demonstrated by control environmental TLD's. Possible doses due to site operations are a minute fraction of this particular natural exposure.

During 1988, the presence of several fission product radionuclides was noted in several environmental sample media.

These media included air, fish, milk, and food product (garden vegetables). The source of the fission product radionuclides is, for 'the most part, past weapons testing and the Chernobyl Nuclear Plant accident. One sample medium, air radioiodine (one weekly sample) showed activity that was most likely a result of operations at the site. The impact, expressed as a dose to man, is minimal and is insignificant when compared to the natural background dose. In actuality, the impact from this sample medium is not measurable because samples were obtained from an on-site location and no activity was measured at nearby, critical off-site locations.

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

SUMMARY

NINE MILE POINT NUCLEAR STATION UNIT 1 DOCKET NO. 50-220 NINE MILE POINT NUCLEAR STATION UNIT 2 DOCKET NO. 50-410 OSWEGO COUNTY, STATE OF NEW YORK, JANUARY DECEMBER 1988*

Data for Table 20 is based on Technical Specification required samples unless otherwise indicated.

LLD values as required by the Radiological Technical Specifications.

LLD units are specified in the medium column.

Location is distance in miles and direction in compass degrees based on NMP-2 reactor centerline. Units for this column are specified in medium column.

The Technical Specifications specify an I-131 and tritium LLD value for surface water analysis (non-drinking water) of 15 pCi/liter and 3000 pCi/liter respectively.

The Technical Specifications do not specify a particular LLD value for environmental TLDs. The NMP-1 and NMP-2 Off-Site Dose Calculation Manuals contains specifications for environmental TLD sensitivities.

The Technical Specification criteria for indicator milk sample locations includes locations within 5.0 miles of the site. There are no milk sample locations within 5 0 miles of the site.

Therefore, the only sample location required by the Technical Specifications is the control location.

Fraction of number of detectable measurements to total number of measurements. Mean and range results are based on detectable measurements only.

The results for TLD 885 must be evaluated with the knowledge that this TLD is in close proximity (300-500 feet) of the Nine Mile Point Unit 1 reactor building and the radwaste buildings. This TLD, as well as other TLDs in this area, are adjacent to the lake shoreline which's a restricted area to members of the public. There are no residences or private property near this area.

Data includes results from optional samples in addition to samples required by the Technical Specifications. For food products, only broadleaf vegetation was evaluated.

Cs-137 is probably an indirect result of the 1986 Chernobyl Nuclear Plant accident.
