ABSTRACT This report presents the data obtained from the analyses of environmental samples collected for the American Electric Power Service Corporation Donald C.

Cook Nuclear Station Environmental Radiological Surveillance Program for the period 01 January 1983 through 31 December 1983.

The activity present above the detection limits in the routinely collected sample media was obser'ved to be of natural A

and atomospheric origin.

In no case did radioactivity from the Cook Nuclear Plant exceed the design objectives of the Cook Radiological Environmental Technical specifications.

INTRODUCTION The Donald C.

Cook Nuclear Station of American Electric Power Service Corporation consists of two >lestinghouse PNR units (Unit 1

and Unit 2).

Each unit consists of a presurized water reactor (PllR) which generates about 3250 megawatts (K0) of heat to generate about 1100

~iW of electricity.

The station is located in Benton Harbor, Michigan.

The D.C.

Cook Plant utilizes a pressurized water reactor with a radwaste hold-up and treatment system that has been designed to keep radioactive releases to" as low as is practible levels.

However, small quantities of noble gases and radioiodine may be released to the surrounding environment.

The quantities of radionuclides released to the environment are expected to be minisule and insignificant as a

source of potential exposure to flora and fauna in the area.

However, direct radiation exposure to man and radionuclide accumulations in various components of food chains to man are carefully monitored.

The environmental radiological monitoring program is intended to serve the following purposes:

a)

To yield average values of radiation levels and concentrations of radioactive material in various media of the environment.

b)

To identify sample locations and/or types of samples that deviate from the averages.

c)

To document seasonal variations that could be erroneously interpreted when the power station is operating.

d)

To indicate the range of values that should be considered "background" for various types of samples.

The basic approach for the Donald C.

Cook Nuclear Plant is to con-trol the release of radioactive material at levels far below that which would be expected to cause detrimental impact on the environment.

The environmental radioactivity surveillance program will be closely coord-inated with conditions of plant operation and subject to periodic review.

Levels of environmental radioactivity are subject to change for reasons in no way related to the operation of the D.C.

Cook Nuclear Plant.

Therefore, the radioactivity surveillance program has been de-signed to include reference or "background" stations as well as "indicator" stations.

The program is summarized in Table I.

This report contains a compilation of the results of analyses of various types of samples collected during the period January 1983 through December 1983.

SECTION 2

SAPLING PROGRAM

All samples are collected by Eberline personnel and shipped to Eberline, Albuquerque Laboratory in New Mexico.

The sample collection procedures remained the same as those detailed in the semi-annual report for the period 01 January through 30 June ]973.

Upon receipt of the samples, the Laboratory staff enters the samples in a log book identifying them as to sample type, collec-tion date, and sample code number of location, then v'erifies the specific analyses to be performed on each sample.

The samples are then stored, awaiting analysis, on shelves expressly for this pur-pose to assure accountabili.ty through the Laboratory processes.

Table 1 lists the sample analysis program sampIe type, frequency, and the type of analysis required.

Table 2 lists the LLD's (Lower Limits of Detection) for the analy-tical program.

These LLD's are based on the Regulatory Guide 4.8.

For analyses not listed in Regulatory Guide 4.8, Federal EPA, former require-

~

ments for similar programs or other appropriate guides are used.

The LLD's are calculated at the 3a (99% confidence) level.

The Guide specifically states that the LLD's are priori, not a posteriori (after the fa'ct) limit for a particular measurement.

When

however, RG 4.8 or other LLD's have not been achieved, a footnote giving a brief explanation has been inserted.

Maps of sampling locations are shown on pages ll-13.

Figure I gives the air sampling locations, Figure II shows other.sampling locations and TLD monitoring locations.

SECTION 3 ANALYSES PROGRAM 14

ANALYTICALPROCEDURES Samples received at the laboratory are analyzed for the various rad'o-active components by standard rad'ochemcal methods.

These methods are equal to, and in most cases, identical with, those of the U.S.D.O.E.1 or those of the Federal E.P.A.2 Br'ef descript"'ons of analytical procedures are available in the Lab-oratory Procedures manual available at the Cook Nuclear Plant and the radioanalytical contractor's laboratory.

AIR PARTICULATE FILTERS Gross Beta Exposed air particulate filters are counted in low back-ground Geiger or proportional flow'eta counters using anti-conc"'dence background suppress'on after the short-lived naturally occurring radon and thoron daughters have decayed.

Filters are counted long enough to ensure that the required sensitivity (LLD) is met.

Gamma Isotopic

~!onthly composites of air particulate filters grouped by 'nd'cator and background stations into two samples are counted in high resolution (GeLi) gamma soectrometers for periods of time 'ong enough to ensure that the required program sensitivity (LLD) is met.

Results of all the analyses for January through December 1983 are presented in full in section 5, Data Tables pages 33 through 48.

Table 3 summarizes the range and average concentrations for meas-urements at the indicator and.control locations with the highest annual mean.

Specific finding for the various environmental media are discussed below.

AIR PARTICULATE SAMPLES Atmospheric particulate matter at a fi.eld location is accumulated for a one-week on a glass fiber filter using a low-volume air sampler at a collection rate of one'cubic foot per!minute.

This particulate matter contained on the filter is counted for beta activity in a low background counting system after the short-lived naturally-occurring radon and thoron daughters have decayed.

The average gross beta concentration for the yea" for all indicator tations was.0.03 pCi/m

, and wars 0.03:pCijm. for. the background station 3

l Data for anayses of individual filters are given on pages 33 through 36 in Section 5.

The following table summarizes the average gross beta concentrations for both indicator and background stations for each year from 1973 through 1983.

The preoperational data were collected in 1973 and 1974; operational data were collected from 1975 through the present.

0. 11 0.03 0.03 The elevated levels of gross beta activity at both indicator and background locations during preoperational and operational phases from 1974 through 1982 were mainly the result of nuclear test explosions in the atmosphere by the people's republic of China.

Such tests took place on 27 June

1973, 17 June

1974, 23 January

1976, 26 September

1976, 17 November

1976, 17 September

1977, 13 birch 1978, 14 December 1978 and October 1980.

The data indicate that there is significantly no difference between the levels of gross. beta activity measured at the indicator aud back" ground locations for the operational and preoperarional phases of the progran..l The activity detected are not attributable to the operation of the Cook Plant.

Airborne I-131 concentration was. less than 0.1 pCilm for all 3

samples received.

The gamma spectrometry data for monthly composites of air particulate files begins on page 37.

Be-7, a naturally occurring nuclide formed by tne cosmic ray interaction with nuclei in the upper atmosphere, was detected in the composites.

These were generally in the range to be expected from measurement of this nuclide, in this medium.

No other gamma emitters were detected.

1 See Annual Environmental Ãonitoring Reports for D.C.Cook Plant from previous years for details.

27

Quarterly composites of air particulate filters were analyzed for Sr-89 and Sr-90.

Sr-89 concentrations were below the detection limit of 0.002 pCi/m3, and Sr-90 were also below the detection limit of 0.001 pCi/m3 for both indica-tor and background locations.

Data are presented on page 37.

The Sr-89 and Sr-90 analyses were deleted from the program beginning second

quarter, 1983.

MILK SAMPLES Milk samples were collected monthly and were analyzed for I-131, Sr-89, Sr-90 and gamma emitters.

Sr-89 and Sr-90 analyses were deleted from the program beginning April 1983.

Sr-89 concentrations measured below the detection limit of 5 pCi/l in all samples collected during the year.

Sr-90 concentrations continued to display considerable variation, which is typical for thip type of sample.

This nu-elide is attributable to worldwide fallout from both recent and older nuclear thes programs.

Data are given on page 39 I-131 concentrations were below the detection limi.ts of the program.

Data are presented on pages 39 and 41.

Gamma emitters other than those which occur in nature were not detected in all smaples at a measurement sensitivity of 10 pCi/1.

Data age given on pages 40 and 42.

PRECIPITATION SAMPLES Gamma isotopic analyses of monthly precipitation samples from indicator and background locations indicate the presence of no gamma emitters in concen-trations exceeding 10 pCi/l (<3000 pCi/m ).

This;sample type was deleted from 2

the program beginning May 1983.

Data are presented on page 43

'ELL WATER SAMPLES Well water is collected from seven locations at 18 week intervals during the year and analyzed for tritium and gamma emitters.

28

Concentrations of tritium in the range of 600 to 8400 pCi/1 were detected in samples from all the indicator stations during the year.

Some of the samples contained small amounts of hydrocarbons and these may have inter-fered with the measurement and contributed to the activity to some extent.

It is possible that the tritium found in these samples is a result of plant operations.

Gamma emitters were below the detection limit in all samples analyzed.

Data are presented on page 45.

LAKE MATER S34%'LES Samples of water from Lake Michigan are composited by indicator and background locations and analyzed for gamma emitters on a monthly basis.

This sample type was deleted from the program beginning May 1983.

The gamma emitters in the monthly composites were measured to be less than the detection limit of 10 pCi/1 per nuclide for all samples.

Data are given on page 44.

SEDIMENT SAMPLES Sediment samples were collected twice during the year from areas north and south of the plant, at the on-site and off-site locations.

The sample were analyzed for gamma emitters.

The gamma emitters were below the detection limit of 0.15 pCi/g (dry) 1 in all samples.

Data are given on page 46.

FISH S&fPLES Fish samples collected from areas north and south of the plant, both on-site and off-site locations, were analyzed for gamma emitters.

For.all samples, gamma emitters were below the detection limit of 0.13 pCi/g (wet).

Data are given on page 46.

29

FOOD'CROP SA"PLES Broad leaf vegetables were collected during the fall harvest period from on-site and off-site locations and were analyzed for gamma emitters.

They were found to be below the detection limit of 0.06 pCi/g (wet) at both on-site and off-site locations.

Data are given on page 46.

GAMMA DOSE Gamma radiation dose was measured with Thermoluminiscent Dosimeters (TLDs) on a quarterly schedule.

A total of.23 locations (9 indicator and 14 background) were monitored during the year.

Throughout the year, there was no statistically significant difference in dose rates between indicator and background locations, nor do they differ significantly from dose rates measured in precious years.

Data are presented on page 4/.

SECTION 5 DATA TABLES 31

INTRODUCTION TO THE.DATA TABLES The following information wiX1 be helpful in understanding the presentation of the data in the tables in this section.

Wet Weight a reporting unit used with organic tissue samples such as vegetation and animal samples in which the amount of sample is taken to be the weight as received from the field with no moisture removed.

Dry Weight a reporting unit used for soil and sediment in which the amount of sample is taken to be the weight of the sample after removal of moisture by drying in an oven at about 110 for about 15 hours1.736111e-4 days <br />0.00417 hours <br />2.480159e-5 weeks <br />5.7075e-6 months <br />.

pCi/ms a reporting unit used with air particulate and radioiodine data which refers to the radioactivity content expressed in picocuries of the volume of air expressed in cubic meters passed through the filter and/or the charcoal trap.

Note that the volumes are not corrected to standard conditions.

Gamma Emitters or Gamma Isotopic samples were analyzed by high resolution (GeLi) gamma spectrometry.

The resulting spectrum is analyzed by a computer program which scans from about 50 to 2000 kev and lists the energy peak of any nuclides present in concentra-tions exceeding, the sepsitivity limits set for that particular experiment.

NA, NS, NR used in place of a concentration when a sample was not available (NS), or when a sample was not analyzed for some specific measurement (NA), or when an analysis is not required (NR).

Error Terms figures following "+" are error. terms based on counting uncertainties at the 2a (95% confidence) level.

Values pre-ceded by the "<" symbol were below the stated concentration at the 3a (99% confidence) level.

Exponents Exponents necessary to prevent data tables from being cumbersome are handled in the conventional manner of including them in the column headings.

Sensitivity In general, all analyses meet the sensitivity requirements of the program as given in Table 2.

For the few samples that do not (because of inadequate sample quantities, analytical interferences, etc.)

the sensitivity actually obtained in 'the analysis is given.

Comment when all analyses of a particular type during the period resulted in concentrations below the sensitivity limits, a statement is made on the appropriate table rather than presenting a whole page of "<" data.

If all but one or two data points are below the sensitivity limits, the previously mentioned convention is followed and the finite data are given as footnotes.
