1.0 INTRODUCTION
The Nuclear Fuel Services, Inc. scent fuel reprocessing plant is located at the Western New York Nuclear Service Center, a 3,345-acre site located apprcximately 30 miles southeast of Buffalo in Cattaraugus County in western New York.
The purpose of this plant was to recover the reusable uranium and plutonium contained in spent nuclear pcwer plant fuels. This recovery was accomplished by the mechanical separation of the fuel materials from their associated hardware, folicwed by the chemical seaaration o'f the uranium and plutonium from the asscciated fission product eierents in the fuel materials. The recovered uranium and plutonium was shipped off site.
Reprocessing operations were suspended March, 1972. The plant is maintained in a safe shutdown condition.
Since the plant startup in 1966, monitoring of ti,e environment by NFS and cognizant government agencies has shown that exposures to radiation of the general population in the vicinity of the plant are not significantly different from those received in other portions of the state. The exposure levels that do exist in the area are attributed to natural background radiation and northern hemisphere fallout from past weapons testing.
Nuclear Fuel Services maintains an extensive environmental prooram to assess the impact of the reprocessing plant on the surrounding environment. This is augmented by comoletely independant environmental monitoring programs carried out on a routine basis by the New York State Department of Environmental Conservation.
The NFS environmental monitoring program provides a measure of the current environmental background surrounding the reprocessing plant.
Samples collected at points where concentrations of effluents in the environment are expected to be the greatest are compared, where possible, with samples collected at points unaffected by plant operations.
The latter samples proside background measurements as a basis for y
distinguishing radioactivity introduced into the envircnment by the operation of the plant from that due to other sources.
The sampling schedule assures that potentially significant changes in the environ-mental radioactivity are sampled most frecuently.
Those which are less affected by transient changes but ray show long-term accurulatiens 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 NFS 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.

4 2.0 SUPRARY OF RESULTS During the first half of 1979, over 800 separate analyses of air, water, fish, 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.
'uclear Regulatory Commission.
The concentration of radionuclides in Cattaraugus Creek during the first six months of 1979 average 0.36% of MPC with a maximum observed concentration of 0.48% of MPC.
The concentration of radionuclides in stack during the first six months of 1979 average 0.03% of the Technical Specification limit with the maximum observed at 0.07%.
The concentration of radionuclides in perimeter air remained the same as samples for the last half of 1978. The direct radiation from the environment remained stable at the 1978 determined average.
y
4 3.0 LIOUID EFFLUE!!TS Liquid wastes are ccliected in twc 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 Icw level waste treatmert plant was put into operation to reduce cesii,m and strontium concentration in the liquid wastes.
Tyoically the plant removes g54 of the cesium and 99% of the strontium frcm the lia'Jid wastes.
Following treatment, the liquid wastes are collected batchwise in two small lagoons.
T1.e 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 2" samples were used to make up the one monthly composite.
Table 3-1 surmarizes the monthly licuid discharge as determined by composite analysis and flow measurements.
In addition to the data presented in Table 3-1, a quarterly comoosite 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 first and second quarters of 1979 indicated principle radionuclides present were cesium-137 and potassium-40.
Table 3-3 shows gross alpha and gross beta results on v
8-samples. Water samples taken frcm Buttermilk Creek during the first and second quarters of 1979 and analyzed for gross alona, gross beta and tritium are shown in Table 3-4.

4.0 GASECUS EFFLUENT Gaseous plant effluents are sar -led in the plant stack. The stack sampler contains a filter to cellect carticulates and an impregnated charcoal filter to colle:t icdine.
Samples are recoved 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 cperators if pre-sec limits are apcroached. The filter paper on the particulate man':ce is advanced daily and will alann 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 ;eriod 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 shcwn on Table 4-2.

5.0 EfWIR0t; MENTAL MEASUREMENTS In the first half of 1979, the average concentrations of gross radioactivity and the average concen ration of specific radionuclides in environmental samples of air, water, milk, fish, and silt continued to be less than applicable linits of the U. S. Muclear Regulatory Conmission.
5.1 AIR MONITORING Particulate air activity is continuously sampled at three perimeter sampling stations. 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 A total of 78 weekly samples were collected during the first plant.
half of 1979 and analyzed for gross alpha and gross beta particulate radioactivity. To allow for decay of naturally occurring snort lived radioisotopes such as lead-212, lead-214, and their daughter prcsc:s, 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.

site perimeter.
Data obtained for January through June 1979 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 The weekly and analyzed for gross alpha, gross beta and tritium.
results of these analyses are shown in Table 5-3.
The 27 weekly samples were ccmposited based on creek flow and analyzed for gross y
alpha, gross beta and Strontium-90.
The Iodine-129 was calculated from Lagoon 3 composite.
Data is shown in Table 5 a.
5.4 FISH During the second and third quarters of each year,, FS takes fish 1
samples from Cattaraugus Creek between the point of discharge of Buttemilk Creek and the Springville hydroelectric dam, two miles downstream. The results of analysis on the fish samples collected for the second quarter of 1979 are shown in Table 5-5.
