1.0 INTRODUCTION

~

The Nuclear Fue1~ Scryices Inc. spent fuel reprocessing plant is located at the. Western New York Nuclear Service Center, a 3,345 ~ " -- - -

acre site located approximately 30 miles southeast of Buffalo in C$ttaraugus County in western New York.

The purpose of this: plant was to recover the reusable uranium and plutonium contained in spent nuclear-power plant fuels. This recovery was accomplished by the mechanical separation of.the fuel materials from their. associated hardware, followed by the chemical separation of the uranium and plutonium from the associated fission product elements:

in the fuel materials. The recovered uranium _and plutonium was shipped.

off site. Reprocessing operations were-suspended March,1972. The-r plant is maintained in a safe shutdown condition.

Since the plant startup in 1966, monitor.ing of. the environment:byc.~.= +n NFS and cognizant government agencies-has shown.that exposures-to-- u

>=c ac radiation of the: general population -in the vicinity of the. plant-are 1_

not significantly different from those received in other portions of-the state. The exposure levels that do exist in the area are attributed 1

.t.......

to. natural background radiation and northern hemisphere fallout from.._.....

...a j past weapons testing.

Nuclear Fuel Services maintains an extensive environmental program to assess the impact of the reprocessing plant on the surrounding

-environment. This is augmented by-completely independent environmental "--- -- q 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 pr' ovide background measurements as a basis for

-m y.-,

2-

. 4 distinguishing radioactivity introduced into the environment 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-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 signifigant

~

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.

l 2.0 SUM 4ARY OF RESULTS During the first half of 1981, 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. Nuclear Regulatory 7,..

Commission.

The concentration of radionuclides"n-Cattaraugus Creek during the first six months of 1981 average 1.3(n of MPC with a maximum observed concentration of 2.31% of MPC.

The concentration of radionuclides in-the stack during the first six months of 1981 average 0.04% of the Technical Specification limit with the maximum observed at 0.08%.

The concentration of radionuclides:in~ perimeter air for the first" - ---

i half of 1981 was higher than samples from previous years. The increase rv;: n in airborne activity is due to. springtime transfer of radioactivity.. _..

from the stratosphere to the troposphere. The stratosphere stores long-lived fission products from weapons testing ' The 1981 springtime -

increase in airborne activity is higher than normal due to the increased

- ---- inventory of weapons testing - fission products' and the-increased -- ---- ---

r- - --'

particulate matter in the stratosphere. The fission product inventory increased with the October, 1980 Chinese bomb test. The increase in particulate matter is due to Mt. St. Helen's eruptions. The particulate

- has-become contaminated with the-weapons testing long-lived fission-- -

products. 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 l

~

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 liquid wastes. Typically the plant removes 96% of_the cesium 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.

L-The water which collects in the number 3-storage lagoon is discharged to:

2

_ =.

the creek system through a. calibrated weir. - During times of~ discharge, daily grab samples are taken from the weir and-analyzed for gross-beta r====

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 91 samples were used to make up the five monthly composites. Table 3-1 sumarizes the monthly liquid 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 Buttennilk Creek is taken quarterly near the Thomas Corners Road Bridge and analyzed for gama emitting radionuclides. Samples in the first and second quarters of 1981 indicated principle radionuclides present were cesium-137 and ootassium-40. Table 3-3 shows gross alpha and gross beta results on

7-8-

samples. Water samples taken from Buttemilk Creek during the _first and second quarters of 1981 and analyzed for gross alpha, gross beta and tritium are shown in Table 3-4.

1 4.0 GASECUS 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 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 period at the limit set by

in environmental samples of air, water, milk, fish and silt continued to be less than applicable limits of the U. -S. Nuclear Regulatory -

Commission.

5.1 AIR MONITORING Particulate air. activity is continuously sampled.at three. perimeter.

m=r 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 plant. A total of 78 weekly samples were collected during the first half of 1931 and analyzed for gross alpha and gross-beta particulater rc =::: s

-radioactivity. To allow for-decay.of naturally occurring shorteljved - -

. radioisotopes such.as lead-212, lead-214;:and:their daughter., products, - : r :cnc 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.--

.-- c m -e-

5.2 BACKGROUND

RADIATION Radiation background measurements around the site are determined by using energy corrected CaSO :Tm TLDs at 16 locations around the NFS 4

site perimeter. These dosimeters are changed and evaluated monthly.

Data obtained for.lanuary through June 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-balf 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 Lagoon 3 composites. Data is shown in Table 5-4.

5.4 FISH During the sec'ond and third quarters of each year, dFS takes fish samples from Cattaraugus-Creek between the point of disciarge of-Buttermilk Creek and the Springville hydroelectric dam, two miles dowt: stream. The results of analysis on the fish samples collected for the second quarter of 1981 are shown in Table 5-5.
