O ABSTRACT This report summarizes data obtained on samples received ,

during the year 1983 for the environmental radiological monitoring program for the River Bend Station of Gulf State Utilities.

.O All samples are collected by Culf State Utilities per-sonnel and shipped to Eberline Laboratory. Albuquerque, l New Mexico. Upon receipt of the samples, the Eberline Laboratory staff identifies them by sample number, sample type, collection date, sample location, and the

,C) specific analysis to be performed on each sample. The information is written up on a work order and entered in a log book.

The data obtained to date were within the expected ranges for environmental media and indicated the presence of i) radioactivity attributabic to natural or fallout orgin.

A summary of Quality Control data obtained during the voar l is presented at the end of the report. Included in this

! section are data obtained from Intra-and Interlaboratory

! comparison programs.

1.0 INTRODUCTION

gg 1

River Bend Station is in West Feliciana Parish 3 km (2 mi) east of the Mississippi River and approximately 38.4 km (24 mi) north northwest of Baton Rouge, Louisiana. ,

The reactor for the River Bend Station is warranted for a core thermal power of 2,894 MWt (BWR designed by GE). Reactor output ,

at rated plant operating conditions is 2,887 MWt, which corresponds to a net station electrical output of approximately 936 MWe.

Dissipation of waste heat will be accomplished through a closed gg cycle system, utilizing multi-cell mechanical draft cooling towers. Makeup water will be withdrawn from the Mississippi River through submerged intake screens and suction pipelines to a dry pit pumphouse structure. Blowdown from the main cooling  ;

water system is discharged to the river through a buried pipe located downstream of the intake structure. The design will gp'

- minimize radioactive releases and insure that radiation dose attributed to the plant operation will be "as low as reasonable  ;

achievable".

The scheduled completion date of construction and fuel loading is spring 1985 with an anticipated commercial operations date gg:

of spring 1986.

Tha sample pump, metering devices, and timer were in a weather-proof housing. The filter and charcoal cartridge were located in an outlet parallel to and about 1 meter above the ground.

Glass fiber filters were used to collect the particulate matter and activated charcoal cartridges (TEDA type) were used to

O MILK SAMPLES Milk samples were collected from McKowen Dairy (indicator station, O about 4.2 miles from the plant), semi-monthly during pasture and monthly during other times. Iodine carrier sodium bisulfite and formaldehye solution were added to the milk collected in a gallon size plastic container. The container was labelled (location, collection date, sample volume collected, etc.), and shipped to Eberline for analysis. O WATER SAMPLES Surface water samples are collected as a composite over a 1-month period from three locations. The locations are St. Francisville Ferry Crossing (control location, 4.2 km upstream f rom the plant O liquid discharge), Crown Ze11erbach (indicator station, 3.9 km downstream from the plant liquid discharge), and blowdown discharge area.

Ground water samples are collected quarterly from the dewatering discharge location in East Creek, tributary to Grants Bayou. O SEDIMENT SAMPLES Approximately 1 kg of shoreline sediment sampics are collected semi-annually from the Mississippi River upstream and downstream of the plant. O VECETABLE SAMPLES Approximately 1 kg of vegetable sampics were collected from onsite location, and state penitentiary at Angola when availabic.

O DIRECT RADIATION USING TLDs Thermoluminiscent doolmeters (TLDs) were placed for ffeld exposure and collected on a monthly and quarterly frequency. Environmental radiation doses are measured using badges, comprised of five chips O

segled in a plastic protective holders having a density of 50 mg/

cm . The TLD chips are 1/8"x1/8"xl/32" LIF known conmercially as TLD-100.

Prior to installation, the chips are annealed by a standard cycle of 60 minutes at 400*c and immediate cooling to ambient temperature by placing the tray containing the annenled chips on an aluminum O block 12"x12"xt".

The TLD badges are placed at 16 inner ring locations (in the general area of the restricted area boundary), 16 outer ring locations (6 to 10 km from the site), 3 control locations, and 7 locat ionn of special interest. O 2-3 9

  • (1) The number, medium, frequency and location of sampling may vary. At times, it may not be possible

! or practical to obtain samples of the medium of choice at the most desired location or time. In these instances, suitable alternative medims and locations will be chosen for the particular path-l vay in question.

(2) Particulate sample filters will be analyzed for gross beta 24 hr or more after sampling to allow l

for radon and thoron daughter decay. If gross beta activity in air or water is greater than 10 times the yearly mean of control samples for any medium, ga-a isotopic analysis will be performed on the individual samples.

(3) c- isotopic analysis means the identification and quantification of gama-emitting radionuclides that may be attributable to the effluents from the facility or from weapons testing fallout.

Federal Environmental Protection Agency (IPA).

i f Analyses of individual sample types, and general methods are discussed j below. The analytical detection limits (Lower Limits of Petection -

O LLDe) are given in Table 3.

In environmental radiological analyses the dominant known uncertainty is usually the sample count rate. Error terms given in this report are based on this factor since all other analytical uncertainties are relatively eas11. Uncertainties are calculated by standard methods (see ref.4), and eO .

O Results are reviewed by the laboratory manager. If a problem is in-I dicated by the data, the nature of the problem is investigated and corrective steps taken immediately. A copy of each report is also provided to the O

Quality Assurance Manager of the Nuclear Services Division.

C. Quality Assurance Plan The Quality Assurance Program follows the requirments of Company and O

Division Manuals. The discussion below outlines Quality Assurance Prograns as conducted in the laboratory and as required in our QA Manuai.

Procedure Approval O

Each procedure goes through a vigorous evaluation and review process before it is incorporated into the EIC Procedures Manual. Established pro-cedures of the Environmental Protection Agency (EPA) or the Environmental O

Measurements Laboratory of the US Department of Energy (EML) are used unless thorough testing has demonstrated that an alternate procedure is equal to or better than the EPA or EML procedure. Uniform procedures are used at both O

laboratories to the fullest cxtent possible, except when deviations are necessary to meet the specific requirements of the client. The manager of j each laboratory and the quality assurance manager review and approve signif- l Ol icant procedural changes before they are implemented.

Equipment Calibration and Maintenance Equipment used for qualitative or quantitative measurements is care-G>

fully calibrated and maintained with records of each calibration or main-tenance action kept in appropriate logbooks. To the extent possible, certified standards are used for all primary calibrations. The following O

standards are used for the application indicated:

3-6 9

l o

Measurement Calibration Standard Cross Beta Solution of Standard I37 Cs certified by NBS or O Amersham Searle 3

Tritium Solution standard of H certified by NBS Gamma Solution standards of various gamma emitters Spectrometry certified by NBS or Amersham Searle. Standards O are used to calibrate each counting geometry used.

Strontium-89 90 Solution standards of Sr certified by Amersham and 90 Searle or NBS Gross Alpha 9 Solution standards of Pu certified by NBS or O A ersham Searle.

3 Radiation Dose Cs gamma source cross-referenced with NBS using R-meters. 226 Ra is used for some special application.

O When suitable standards are not available for a specific gamma emitter, quantitative gamma isotopic analysis is based on an energy calibration of the gamma spectrometer and the gamma energy and ry s.bundance information provided in Table of Isotopes, Sixth Edition by Ledrer, Hollander, and Perlman.

The results of the Quality Control Programs are summarized in O

v 4.1 AIR PARTICULATES AND AIRBORNE I-131 The gross beta particulate data during the year remained at low levels and were generally in the range to be expected from measurements of this type in the medium.

The Iodine-131 concentration in charcoal cartridges was below the detection

() limits of the program.

Gamma spectral analysis of the quarterly composites of the weekly air filter collections indicate the presence of no gamma emitters in concentrations exceeding the detection limit of the program.

I

() Data for these analyses are listed in section 5.0, pages 5-2 to 5-8.

i 4.2 WATER SAMPLES Gross beta analysis of the monthly samples during the year remained at low levels and were generally in the range to be expected from measurements

() of this type in the medium. Gamma spectral analysis of the monthly samples indicate that the gamma emitters concentrations were below the detection limit of the program.

Quarterly composite of the monthly samples were analyzed for tritium.

The tritium concentrations were below the detection limit of the program.

/)'

The data for these analyses are listed in section 5.0, pages 5-9 and 5-10.

Ground water samples were collected from one location and were analy::ed for gamma emitters and tritium. The results indicate that the concentra-tions of gamma emitters and tritium were below the detection limit of the

() program.

The results of these analyses are listed in section 5.0, page 5-11.

4.3 SEDIMENT SAMPLES

() Sediment samples were collected in November, 1983, and analyzed for gamma emitters. The results indicate that the concentrations of gamma emitters were below the detection limit of the program.

The results of these analyses are listed in section 5.0, page 5-12.

() 4.4 MILK SAMPLES

\

Milk samples were collected from McKowen Dairy and analyzed for Iodine-131 and gamma emitters. The results indicate that the concentrations of Iodine-131 and gamma emitters were below the detection limit of the program.

() The data are listed in section 5.0, page 5-13.

O l 4.5 ANIMAL SAMPLES Deer thyroid, deer meat, and deer bones were collected and analyzed by gamma spectrometry. The results indicate that the concentrations of GD gamma emitters were below the detection limits or the program for all samples. The data are listed on page 5-14.

l 4.6 VEGETABLE SAMPLE e

Vegetable samples were collected from two locations, and analyzed for gamma emitters. The results indicate that the gamma emitters concentrations were below the detection limit of the program.

The data are listed in section 5.0, page 5-15.

O 4.7 ENVIRONMENTAL DOSIMETRY (TLDs)

Measurements of environmental dose rates were made on a quarterly basis using thermoluminiscent dosimeters (TLDs). The dose rates measured were normally in the range to be expected as background levels.

O The data are presented in section 5.0, pages 5-16 and 5-17.

O 5.0 COMMENTS ON, AND TERMS USED IN DATA TABLES l() Wet Weight A reporting unit used with organic tissue samples such as vegetation and animal samples in which the amount of j

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 l() amount of sample is taken to be the weight of the sample after' removal of moisture by drying in an oven at about 1100C for about 15 hrs.

! pCi/m A reporting unit used with air particulate and radio-iodine data which refers to the radioactivity content

-() expressed in picoeuries 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, l

j Gamma Emitters Samples were analyzed by high resolution (GeLi) gamma i j() or spectrometry. The resulting spectrum is analyzed by a Gamma Isotopic computer program which scans from about 50 to 2000 kev

' and lists the energy peaks of any nuclides present in concentrations exceeding the sensitivity limits set for

.i that particular experiment.

  • C) Error Terms Figures following "1" are error terms based on counting i j uncertainties at the 20 (95 percent confidence) level. ,

Values Preceded by the "<" symbol were below the stated concentration at the 4.66a (99,99 percent confidence) {

level.

1 lC) Sensitivity In general, all analyses meet the sensitivity require-4 ments of the program as given in Table 3. For the few l samples that do not (because of inadequate sample quan-t tities, analytical interference, etc.) the sensitivity actually obtained in the analysis is given.

i

C) Comment When all analyses of a particular type during the period l

resulted in concentrations below the sensitivity limits, I 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

?C) finite data are given as footnotes, i
