!O l-ABSTRACT

O This report summarizes data obtained on samples received during the l year 1984 for the preoperational environmental radiological

! monitoring program for the River Bend Station of Gulf States Ut ilit ies ,

i All samples are collect ed by Gulf Stat es Utilities personnel and y shipped to Eberline Analytical Corporation, Albuquerque, New Mexico. Upon receipt of the samples, the Eberline laboratory staff

identifies them by sample number, sample type, collection date, t

sample location, and the specific analysis to be performed on each sample. The in f o rm at ion is recorded on a work order and entered in a log book.

'O The data obtained were within the expected ranges for environmental media and indicated the presence of radioactivity attributable to natural or fallout origin.

A summary of quality control result s obtained during the year is

'g presented at the end of the report. Included in this section are data from intra and interlaboratory comparison programs.

1.0 INTRODUCTION

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

i 4- 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 approximate 936 MWe, g:

l Dis s ipation of wast e heat will be accomplished through a closed cycle system, utilizing multi-cell mechanical draft cooling towers. Makeup water will be withdrawn from the Mississippi River through submerged intake screens and suction piplines to a dry pit pumphouse structure. Blowdown from the main cooling water system g is discharged to the river through a buried pipe located downstream of the intake structure. The design will minimize radioactive releases and insure that radiation dose attributed to the plant

operation will be "as low as reasonable achievable".

I The scheduled completion date of construction and fuel loading is g summer 1985 with an anticipated commercial operations date of December 1985.

O 2.1 SAMPLE COLLECTION PROCEDURES I i

AIR PARTICULATE AND RADI0 IODINE , l l

O  :

Air particulate and radiciodine samples were collected weekly from nine locations (Fig. 1). The samples were gathered with a '

portable, low-volume air sampling device which is designed to draw l a constant flow rat e regardless of filt er loading. The sampling devices were set to maintain a flow rate of about 1 cfm. The sample pump, met ering devices, and timer were in a weatherproof O 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 collect radioiodine.

'h* 81*** 'I* fil "** *** '*d " 'h* *i' ***'**" *** P****d O , in a labeled envelope. The charcoal cartridge was removed at the  ;

same time. Air flow readings and sample volumes were recorded and sent to Eberline for, analysis.

The sample collection from location N. Blvd. was started at the .

beginning of June, 1984.

FISH SAMPLES Fish samples were collec t ed s em i-annually from the Mississippi River upstream and downstream of the plant.

ANIMAL SAMPLES Animal samples-(deer thyroid) were collected annually.

O NILE SAMPLES Milk samples were collected from McKowen Dairy (indicator station, about 4.2 miles f rom the plant), s emi monthly during pas ture and monthly during other times. Iodine carrier, sodium bis ulf it e and O formaldehyde solution were added to the milk which was collected in a gallon size plastic container. The container was labeled (location, collection dat e, 's ample volume collected, e t c.), and shipped to Eberline for analysis.

O WATER SAMPLES Surface water samples were collected as a composite over a 1-month period from three locations. The locations were St. Francieville Ferry Crossing (control location, 4.2 km upstream f rom the plant l liquid discharge), Crown Ze11erbach (indicator station, 3.9 km O d * * * * * *" *" t h e P l an t liquid discharge), and blowdown discharge area.

Approximately I kg of vegetation samples were collected f rom the j onsite location, and state penitentiary at Angola. g;

', DIRECT GAMMA RADI ATION ,

i l Thermoluminescent dosimeters (TLD) were placed for field exposure

{ and collected on a monthly and quarterly frequency. Environmental i gamma radiation doses was measured using these badges. The badges O

} consisted of five chips-sealed in a plastic protectiv'e holder 4

having a density of 50 mg/cm2 The TLD chips were 1/ 8" x 1/ 8" x

. 1/32" LiF known commercially as TLD-100.

I i

! Prior to installation, the chips were annealed by a standard cycle of 60 minutes at 4000C and immediate cooling to ambient temperature O by placing the tray containing the annealed chips on an aluminum block 12" x 12" x 1".

1 I The TLD area badges were 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 9 O l locations of specis1' interest.

iO 1 3.0 ANALYTICAL PROCEDURES AND COUNTING METHODS a

Samples received at the Laboratory are analyzed for various radioactive components by standard radiochemical, methods. These

'O

methods,are equal to and in most cases, identical with, those of the USDOE (HASL Procedures Manual, HASL-300, Health and Safety Laboratory, U.S. Atomic Energy Comm is s ion , 376 Hudson Street, New York 10014) or t ho s e o f t h e U.S. Environmental Protection Agency (USEPA). ,

i IO ^"*17'** f i"divid"*1 "P le types, and general methods are i j discussed below. The analytical detection limits (Lower Limit s of 4

. QUALITY ASSURANCE PROGRAM l A. DESIGN OF PLAN

'O.

The management of Eberline Analytical Corporation ( E A C) is committed to a rigorous Quality Assurance Program. While this commitment is necessary f or the normal conduct of busine s s , our basic policies dictate professional ethics based upon concern for a safe and clean environment. This philosophy, and the specific procedures to attain the objectives, form the framework of our

g Quality Assurance Program. Eberline will provide only those services within our qualifications and with confidence that our l Q.A. Program, and all related procedures, permits reliable

! performance of these services.

This quality assurance program complies with applicable Q requirements of the following specifications:

A.1 NRC 10 CFR Part 50, Appendix B " Quality Assurance Criteria for Nuclear Power Plants and Fuel Reprocessing Plants".

A.2 ANSI N4 5.2, " Quality Assurance Program Requirements f o.r O Nuclear Power Plants".

, A.3 MIL-Q-9858, " Quality Program Requirements for Government i Agencies".

A.4 NRC 10 CFR Part 21, " Reporting of Defects and Noncompliance".

O A.5 ANSI /ASME NQA-1-1983, "Qualit y As s u-ance Program Requirements for Nuclear Facilities".

A.6 NRC Regulatory Guide 4.15 Rey. 1, " Quality Assurance for Radiological Monitoring Programs - Effluent Streams and the Environment".

O A.7 ANSI 13.11, " Criteria for Testing Personnel' Dosimetry Performance".

B. COLLABORATIVE TESTING i

In a d d i t i o n- to the internal quality control samples, each laboratory participates in collaborative testing or interlaboratory -

.O comparison programs. Natural or synthetic samples carefully prepar'ed to cont ain . known concentrations of the nuclides are.sent to participating laboratories by an independent referee group such as the Quality. Assurance Branch of the National Environmental Research. Center of the U.S. Environmental Protection Agency at Las Vegas , Nevada or the Environment al Meas urement s' Laboratory, U.S.

O Department of Energy, at New York. After statistically comparing j

O the resulting data from triplicate analyses of the special standard sample, the degree of analytical validity of the results are reported and updated perf ormance inf ormation is returned t o each participant. The program thus enables each laboratory to document 9 the precision and accuracy of radioactivity measurements, identify I instrumental and procedural problems and compare performance with  !

other laboratories.

TLD area badges representative of the current supply, and routinely processed in the same manner as those shipped to customers, are 3, sent quart erly to Bat t elle Pacific Northwes t Laboratorie s (BPNL) for additional performance testing. Upon returning from BPNL, the TLD badges are read out using the s tandard operating procedur es.

The exposures are reported by BPNL f ollowing receipt of the EAC exposure report. Quality Control results are s um m a r iz ed monthly with distribution to the Quality As surance Manager and to others g upon request.

C. QUALITY ASSURANCE PLAN The Quality Assurance Program follows the requirements of the g Company and department procedures manuals. The discussion below outlines Quality Assurance Programs as conducted in the laboratory and as required in the QA Manual.

1. Procedure Approval Each procedure goes through a vigorous evaluation and review process before it is incorporated into the EAC Procedures Manual. Established procedures of the Environmental Protection Agency (EPA) or the Environmental Measurements Laboratory of the US Department of Energy (EML) are used unless thorough testing has demonstrated that an alt ernat ive procedure is equal to or better than the EPA or EML procedure. Unif orm proc edures are O used at both laboratories to the fullest extent possible, except when deviations are necessary to meet the specific requirements of the client. The manager of each laboratory and the quality assurance manager review and approve significant procedural changes before they are implemented.

O

2. Equipment Calibration and Maintenance Equipment used for qualitative or q uan t it a t ive measurements is carefully calibrated and maintained w it h records of each calibration or maintenance action kept in appropriate log books.

To the extent possible, certified standards are used for all G primary calibrations. All dilutions of solution standards are recorded in a log book. Identity of dilutions can be traced back to the initial certification.

O The following standards are used for the application indicated:

O Measurement Calibration Standard Gross Beta Solution of Standard Cs-137 certified by NBS or Amersham Searle.
O Tritium Solution standard of H-3 certified by NBS. <

Gamma Solution standards of various gamma emitters Spectrometry certified by NBS or Amersham Searle.

Standards are used to calibrate each counting geometry used.

O Strontium-89 Solution standards of Sr-89 and Sr-90 and 90 certified by Amersham Searle or NBS.

Gross Alpha Solution standards of Pu-239 certified by NBS or Amersham Searle.

O Radiation Dose Cs-13 7 gamma sour c e' cro s s-r ef er enc ed w it h j NBS using R-meters.
