The Nuclear Fuel Services, Inc. spent fuel reprocessing plant is located at the Western New York Nuclear Service Center, a 3,345-acre site located cpproximately 30 ' miles southeast of Buffalo in Cattaraugus County in western New York. , ,
s The purpose of th'is plant was to recover the reusable uranium and
- plutonium contained in spent nuclear power plant fuels. This recovery
- was accomplished by the mechanical separati6n of the fuel materials 7, y from their associated hardware, followed by the chemical. separation of
, the uranium and plutonium from the associate 1 fission product elements-l
' in the fuel materials. The recovered uranium and pihtonium was shipped
/off site. Reprocessing operations were suspended' March,1972. The
t , plant is maintained in a safe shutdown condition. ' ' \
f s , ,
,i' Since the plant startup in 1966, monitoring of the environment by:
, NFS and cognizant government agencies ,has shown that ex9c ures to radiation of the gener.al. population in the vicinity of the plant-are f
not significantly different from those received in other portions of the state. The exposure levels that'do exist in the aretc are attributed
? + to natural background radiation and northern hemisphere falloit from
) past weapons testing. a

distinguishing radioactivity introduced into the environment by the operation of the plant from that due to other sources. The samplina schedule assures that potentially significant changes in the environ-mental radioactivity are sampled most frequently. Those which are less affected by transient changes but may show long-term accumulations are sampled less frequently.
The NFS environment program at the Service Center began in July, 1963 with a preoperational monitoring program of the background gross alpha, beta and gamma activity at and near the Center. This program has since been extensively expanded to obtain the most significant data. The present UFS environmental program outlined in Table 1-1 provides for over 1,000 analyses per year. The location of the fixed sampling stations operated by NFS at the Center are shown in Figure 1-1.

SUMMARY
OF RESULTS During the last half of 1981, over 800 seoarate analyses of air, water, fish, deer, milk, and silt were performed. These analyses indicated the concentrations of radioactivity in the environmental media are less than the applicable limits of the U. S. fluclear Regulatory Commission.
The concentration of radionuclides in Cattarauaus Creek during the last six months of 1981 average 0.39% of MPC with a maximum observed concentration of 0.49% of MPC.
The concentration of radionuclides in the stack during the last six months of 1981 average 0.07% of the Technical Specification limit with the maximum observed at 0.13%.
The concentration of radionuclides in perimeter air decreased to levels determined for the second half of 1980. The direct radiation from the environment remained stable at the 1980 determined average.
3.0 LIQUID EFFLUENTS Liquid wastes are collected in two interceptor tanks and discharged to holding ponds if activity is less than the technical specification limit. The holding ponds provide surge capacity prior to further treat-ment.
In May of 1971, a low level waste treatment plant was put into operation to reduce cesium and strontium concentration in the liouid wastes. Typically the plant removes 96% of the ces4m and 99% of the strontium from the liquid wastes.
Following treatment, the liquid wastes are collected batchwise in two small lagoons. The water in the lagoon is analyzed for gross beta, cesium-137, and cesium-134. If cesium-134 and cesium-137 are below their respective MPC, the lagoon is transferred to the number 3 storage lagoon.
The water which collects in the number 3 storage lagoon is discharged to the creek system through a calibrated weir. During times of discharge, daily grab samples are taken from the weir and analyzed for gross beta
~
activity. These grab samples from the weir are composited, based on lagoon discharge volume, and analyzed monthly for specific radionuclides to determine activity released. A total of 14 samples were used to make up the one monthly composite. Table 3-1 sumarizes the monthly liouid discharges as determined by composite analyses and flow measurements.
In addition to the data presented in Table 3-1, a quarterly composite of weir samples is analyzed for specific alpha emitting radionuclides.
Table 3-2 shows the quarterly liquid discharges based on these analyses.
Buttermilk Creek is the first major on-site stream to receive liquid discharges from the lagoon system. A bottom silt sample of Buttermilk Creek is taken quarterly near the Thomas Corners Road Bridge and analyzed for gamma emitting radionuclides. Samples in the third and fourth quarters of 1981 indicated principle radionuclides present were cesium-137 and potassium-40. Table 3-3 shows gross alpha and gross beta results on

l 4.0 GASE0US EFFLUENT Gaseous plant effluents are sampled in the plant stack. The stack sampler contains a filter to collect particulates and an impregnated charcoal filter to collect iodine. Samples are removed from the stack sampler at least once every seven days and analyzed.
In addition to the stack sampler, a stack monitor is used to continuously determine the particulate radioactivity in the stack air and to alert operators if pre-set limits are approached. The filter paper on the particulate monitor is advanced daily and will alarm if the accumulation of particulate radioactivity over a four-hour period exceeds that.which would occur if particulates were being discharged over the same time period at the limit set by Technical Specifications.
The particulate radioactivity in the stack and the relationship to the Technical Specification limit are shown on Table 4-1. The curies of radioactivity released from the plant stack as determined on a quarterly combined sample is shown on Table 4-2.

5.0 EflVIR0flMEflTAL MEASUREMENTS In the first half of 1981, the average concentrations of gross radioactivity and the average concentration of specific radionuclides in environmental samples of air, water, milk, fish and silt continued to be less than applicable limits of the U. S. Nuclear Regulatory Coninission.
5.1 AIR M0!!ITORIflG Particulate air activity is continuously sampled at three perimeter sampling statfor.s. The Fox Valley sampler is located two miles south-east of the plant, Route 240 sampler is 1-1/2 miles northeast of the plant, and Thomas Corners sampler is 2-1/2 miles north-northwest of the plant. A total of 78 weekly samples were collected during the last half of 1981 and analyzed for gross alpha and gross beta particulate radioactivity. To allow for decay of naturally occurring short lived radioisotopes such as lead-212, lead-214, and their daughter products, the air samples are stored for one week prior to counting. Following this decay period, the long lived activity from natural occurring radionuclides and fallout can be determined. The results of these analyses appear in Table 5-1.
5.2 BACKGROUf!D RADIATIOff Radiation background measurements around the site are determined by using energy corrected CaSO4 :Tm TLDs at 16 locations around the flFS site perimeter. These dosimeters are changed and evaluated monthly.
Data obtained for July through December 1981 are shown in Table 5-2.
5.3 CATTARAUGUS CREEK Samples of water from Cattaraugus Creek are taken with a continuous sampler located about one-half mile downstream from the confluence of Cattaraugus Creek and Buttermilk Creek. These samples are collected weekly and analyzed for gross alpha, gross beta and tritium. The results of these analyses are shown in Table 5-3. The 26 weekly samples were composited based on creek flow and analyzed for gross
alpha, gross beta and Strontium-90. The Iodine-129 was calculated from the Lagoon 3 composite. Data is shown in Table 5-4.
5.4 FISH During the second and third quarters of each year, NFS takes fish samples from Cattaraugus Creek between the point of discharge of Buttermilk Creek and the Springville hydroelectric dam, two miles downstream. The results of analysis on the fish samples collected for the third quarter of 1981 are shown in Table 5-5.
5.5 DEER Deer samples were obtained during October,1981. Results of these samples appear in Table 5-6.
. 5.6 MILK Milk samples from two farms located near the site boundary to the northeast and northwest of the piant are taken yearly in August. Results of these samples appear in Table 5-7.
