s RIVER BEND STATION RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT FOR 1985
1.0 INTRODUCTION
This Annual Radiological Environmental Operating Report for the period of October 31,1985 (date of initial criticality) through December 31, 1985, is submitted in accordance with Technical Specifica-tion 6.9.1.7 of Appendix A to River Bend Station License Number NPF-47.
River Bend Station (RBS) is a 936 MWe General Electric boiling water reactor located in West Feliciana Parish, Louisiana, 4.1 km south-east of St. Francisville (Figure 1). Waste heat from RBS is dissipated via a closed cycle system using four mechanical draft cooling towers which draw makeup water from the Mississippi River, 3.3 (air) km to the west. Blowdown from the normal cooling tower system dilutes low-level liquid radioactive waste and is discharged to the Mississippi River through a 4.4-km buried pipe located downstream of the intake structure (Fig. 2). Gaseous radioactive effluents are released through the Main Plant Exhaust Duct, the Fuel Building Exhaust Duct, and the Radwaste Building Exhaust Duct.
The area within a 16-km radius of RBS includes eubstantial portions of West Feliciana, East Feliciana, and Pointe Coupee parishes, as well as small portions of East and West Baton Rouge parishes. Most of the land in this area is devoted, in about equal proportions, to forests and agriculture (pasture, various crops). Wetlands, streams / lakes, and urban / improved lands comprise the remainder of the immediate vicinity of the plant. Besides St. Francisville (4.1 km northwest), human popula-tion centers near RBS are New Roads (10 km southwest) and Jackson (12 km northeast). Industrial facilities in the immediate vicinity of RBS are Lambert Redi-Mix Company (1.8 km north-northeast); Crown-Zellerbach Paper Mill (5 km south); Big Cajun No. 2 Power Station (5 km southwest);
and the Corps of Engineers concrete casting yard (5 km west).
The area within an 80-km radius of RBS contains portions or all of 19 Louisiana parishes and five Mississippi counties. This area has generally the same makeup as that of the immediate vicinity of RBS, al-though wetlands, agricultural lands, and urban / improved lands are rela-tively more extensive (at the expense of forested lands) in the south-western and southeastern quadrants. Baton Rouge, centered at about 38 km southeast, is the only large city in the general vicinity of RBS.
Radiological environmental monitoring in the vicinity of RBS is performed by the GSU Environmental Services Group, with support from the Plant Staff Radiological Programs Section and an offsite contractor, Eberline Analytical Services (EAS).

o RIVER BEND STATION RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT FOR 1985 2.0 RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM (REMP) 2.1 Purpose / Bases The Radiological Environmental Monitoring Program (REMP) was esta-blished to provide representative measurements of radiation and of radi-oactive materials, resulting from RBS operation, in those exposure path-ways and for those radionuclides that lead to the highest potential ex-posures of members of the public. The REMP implementsSection IV.B.2 of Appendix I to 10CFR50 and thereby supplements the radioactive effluent monitoring program by verifying that the measurable concentrations of radioactive materials and levels of radiation are not higher than expec-ted on the basis of the effluent measurements and the modeling of the environmental exposure pathways.
The REMP applies the concepts of indicator-control and preopera-tional-operational intercomparisons to establish the adequacy of envi-ronmental levels and resultant human radiation doses. In addition to 10CFR50, Appendix I, the program is based on guidance provided in the NRC's Radiological Branch Technical Position, Revision 1, November 1979, as well as Regulatory Guides 4.1 and 4.15.
2.2 Environmental Radiation Exposure Pathways Elements of the REMP monitor indications of the impacts of gaseous (airborne) and liquid effluents released from River Bend Station. The specific methods used in monitoring the pathways by which these efflu-ents could lead to human exposure, based on existing demographic infor-mation, are:
HUMAN EXPOSURE PATHWAYS (A) Gaseous Effluent Pathway Monitoring Media Immersion and Other Thermoluminescence External Dose Dosimetry (TLD) Area Monitors Air Samples (Particulates and Radioiodines)
Ingestion (Internal) Dose Vegetation / Food Crop Samples Milk Samples Air Samples (B) Liquid Effluent Pathway Monitoring Media Ingestion (Internal) Dose Surface Water Samples Groundwater Samples Drinking Water Samples Fish / Invertebrate Samples Shoreline Sediment Samples 4

NOTES:
$$ (1) Sample / measurement location not required by RBS Technical Specifications (not identified in DDCM).
(2) Sampling and/or analysis frequency greater than required by RBS Technical Specifications and ODCM.
(3) The upstream (control) sample is taken at a distance beyond influence of the plant discharge. The downstream (indicator) sample is taken in an area beyond but near the mixing zone.
(4) Gross beta analysis not required by RBS Technical Specifications and ODCM.
(5) Drinking water sampling / analyses not required by RBS Technical Specifications and ODCM. (No drinking water pathway exists due to extreme distance of nearest intake.) The upstream surface water sampling location (SWU) is used as a
" control" for drinking water analyses comparisons.
(6) If milk-producing animals become available within a 5-km radius of the plant, up to 3 samples from these animals will be analyzed in lieu of the leafy vegetables from onsite gardens in high dose-potential areas (see Note 8).
(7) Preferred species are river shrimp, blue catfish, and freshwater drum; if catfish and drum are unavailable, other edible species may be substituted.
(8) No irrigation pathway existe due to the extreme distance of nearest domestic water intake (see Note 5); leafy vegetables are sampled / analyzed because of limited availmhility of milk samples (see Note 6).
(9) Prior to establishment of onsite gardens, leafy vegetable samples were collected from of fsite gardens in WNW, NW, and NNW sectors near the site boundary.
RIVER BEND STATION RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT FOR 1985 (B) Liquid Effluent Pathway (cont.) Monitoring Media Immersion (External Dose) Surface Water Samples Shoreline Sediment Samples Site-related dispersion characteristics, demography, hydrology, land use, anticipated source terms, and the exposure pathways outlined above were considered in the selection of the sample media, sampling and analysis frequencies, sampling / measurement locations, and types of anal-yses. These criteria were used to establish both the preoperational and operational phases of the REMP.
Tht program that evolved during the preoperational (baseline) moni-toring phase, incorporating all of the elements in the RBS Technical Specifications (3/4.12.1, 3/4.12.2, 3/4.12.3) plus special study cri-teria, is illustrated in Table 1 and Figures 1 and 2.
2.3 Land Use Census The annual land use census was conducted from July 30 through August 30, 1985. Table 2 summarizes the results and notes changes in nearest receptor locations from those identified in the RBS Final Safety Analysis Report (FSAR), Several minor differences in distances between those identified in the 1985 census and those used in the FSAR are at-trib6 cable to differences in reference points and measurement scales (e.g., rounding of conversions from miles to kilometers).
The 1985 census identified nearest residences within 8 km of the reactor containment in all sectors except L (SW). No gardens within 8 l km were found in sectors L, M, and N (SW, WSW, and W, respectively).
Gardens identified in sectors P (WNW) and Q (NW) are the onsite gardens l
established in the sectors with the highest calculated annual average ground-level D/Q. These gardens supply broadleaf vegetation for moni-toring in partial fulfillment of RBS Technical Specification 3/4.12.1.
The only milk produced for human consumption within 8 km comes from ;
animals at McKowen Dairy, which is used as a REMP indicator station for milk sampling. ,
Annual average CHI /Q and D/Q values for continuous containment and Radwaste Building vent releases are shown in Tables 3 - 6 to form a basis for evaluating the results of subsequent land use surveys. The values are based on the 1977-79 baseline meteorological data used in the FSAR.

RIVER BEND STATION RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT FOR 1985 2.4 Program Changes from Preoperational REMP Although some radiological environmental data were gathered in 1982, the preoperational REMP is considered to have begun in early 1983.
Baseline REMP results are summarized in Appendix A; greater detail is available in the respective annual reports for preoperational radiologi-cal environmental monitoring (1983,1984,1985) .
The only substantial change in the REMP accompanying the onset of operation was the addition of a sampling point in the liquid discharge line, where an automatic sampler collects hourly aliquots of equal volume which are composited for monthly (gross beta, gamma isotopic) and quarterly (tritium) analyses.
2.5 Program Exceptions Certain samples and analyses were inadvertently omitted or unavoid-ably altered during the 1985 operating period. These exceptions and the reasons for the omissions / alterations are delineated in Table 7 in ac-cordance with Technical Specification requirements. Corrective actions and impacts on program quality are discussed below.
One weekly air sample was altered due to compressor failure; upon discovery of the malfunction the pump was replaced. In changing the discharge line water sampler from a temporary to a permanent power source maintenance personnel inadvertently left the automatic sampler off for eight and three hours, respectively, on two occasions in November. Now that the permanent power hook-up is complete further in-cidents of this type are unlikely. Inasmuch as air and water samples were available for analyses for the periods / locations affected, these exceptions did not significantly impact program quality.
Milk and broadleaf vegetation sampling was incomplete during the operating period. Control samples of milk were collected only once each month because of misinterpretation of procedural requirements. Certain indicator and control samples of vegetation were not_ collected because of limited availability (due to cold weather) and misinterpretation of procedural requirements. Investigation of the omissions revealed inade-quacies in the vegetation sampling and overall REMP scheduling proce- l dures, which~were revised to clarify the intended relationship between '
milk and vegetation sampling. Establishment of a greater variety of leafy vegetable crops was requested to increase the availability of samples during late autumn and winter. Technicians were instructed to j collect at least three types of vegetation -(as available) at each samp- 1 ling location each month. At least some indicator samples of both milk and broadleaf vegetation were obtained in each month of the operating period, so these omissions are not judged to have had a significant I impact on overall program quality. Of greater significance, however, >
was the omission of control samples of broadleaf vegetation, which pre- f cludes indicator-control intercomparisons for this medium during the initial period of operation.

o RIVER BEND STATION RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT FOR 1985 3.0 INTERPRETATION OF REMP RESULTS 3.1 Summary of Operational REMP Results The Radiological Environmental Monitoring Program for 1985 was con-ducted by the CSU Environmental Services Group using a contracted labo-ratory, Eberline Analytical Services (EAS), for most of the analyses.
In-house analytical programs were begun in 1985 to train personnel in calibration and analysis methods. The results for waterborno aca inges-tion pathway media analyses include those from the in-house program, and the results for the direct exposure pathway derived from the Dosimetry Group of the RBS Radiological Programs Section are herein compared with those of the contractor.
Monitoring results for the exposure pathways are summarized in Table 8 and Appendix C. For purposes of data summary, comparisons, and discussion, the sampling locations designated as "Special Interest" in Table 1 are treated as indicator stations if they are within 16 km of RBS and control stations if they are beyond 16 km.
3.1.1 Airborne Exposure Pathway - Measurements of radioiodine and other gamma emitters were all below their respective LLDs (i.e. , " unde-tectable"). Gross beta activities averaged 0.03 pCi/ cubic meter at both indicator and control locations.
3.1.2 Direct Exposure Pathway - Measurements of gamma ray exposure for monthly and quarterly thermoluminescence dosimeters (TLDs) are sum-marized in Tables 8 and C.I. The " quarterly" exposures are taken to be two-thirds of those of the fourth calendar quarter, 1985. EAS reported monthly averages of slightly greater than 11 mR total for both indicator and control locations. One monthly Panasonic TLD (Table C.1) recorded 37 mR total, raising the monthly average for indicator locations to 4.9 mR total. The remaining Panasonic indicator TLD exposures ranged from 2.8 to 9.2 mR total, yielding a monthly average (without the outlying observation) of 4.5 mR total. There was no apparent explanation for the single high measurement; the co-located EAS TLD recorded 12.5 mR total for the corresponding month. Panasonic data are corrected by subtrac-tion for~ transit control badge exposures, whereas those reported by EAS are gross totals. The Panasonic results are mentioned here because they are in generally close agreement with contractor data for 1984 (transit control corrected) and in-house results for early 1986. When all rele-vant information is considered, it is evident that there were no signi-
~
ficant differences between direct radiation exposures at indicator and control locations.
3.1.3 Waterborne Exposure Pathway - No detectable concentrations of any waterborne radionuclides were recorded for November and December, 1985. Gross beta measurements for surface water indicator locations averaged 6 pCi/ liter, compared with 7 pCi/ liter for control locations.
Gross beta activities for groundwater averaged 2 pCi/ liter at both indi-cator and control wells. Drinking water measurements for gross beta averaged 5.5 pCi/ liter at the indicator location (Donaldsonville) and 7 21 i

j s e RIVER BEND STATION RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT FOR 1985 pCi/ liter at the control location (SWU). No tritium was detectable in environmental water samples collected during the initial period of oper-ation. Shoreline sediment sampling was not scheduled in November and December, 1985.
3.1.4 Ingestion Exposure Pathway - Measurements of milk and broad-leaf vegetation during November and December, 1985, detected no radio-nuclides except naturally-occurring K-40 at either the indicator or the control locations. ,
3.2 Comparison of Operational and Baseline REMP Results '
Radioicdine and other gamma emitters in the airborne exposure path-way were not detected above LLDs during the two months of operation (Table 8) nor during the three years of preoperational monitoring (Ap-pendix A). Gross beta measurements for air particulates averaged 0.03 pCi/ cubic meter at both indicator and control locations during operation as they had during the preoperational period.
For the direct radiation exposure pathway, comparisons of opera-tiotlal and baseline data are confounded by the lack of transit control correction for the EAS TLD results in 1983 and 1985 (see Subsection 3.1.' 2) . Therefore, in comparing Tables 8 and A.1 one must consider that th'e Jower baseline'meens are attributable, at least in part, to the averaging of 1984's net (corrected) exposures with the gross (uncorrec-ted) exposures of 1983 and the first 10 months of 1985. A better under-standing is possible through an overall summary of gamma exposure mea-surements, including Panasonic results (Table C.1):

For example, average net (corrected) exposures for monthly TLDs (EAS 1984 data, 1985 Panasonic data) ranged from about 4 to 6 mR total.
During the entire preoperational and initial operating periods no gamma emitting radionuclides were detected in any waterborne pathway sample media. Waterborne gross beta activities were measured at slight-ly lower levels during November and December, 1985, than during the preoperational period for both indicator and control activities. Shore-line sediment was not collected during the operating period of 1985.
For the ingestion exposure pathway, no gamma emitting nuclides were detected above LLDs except K-40 during November and December, 1985.
K-40 was detected via in-house analyses at 1500 pCi/kg in indicator milk and at 3782 pCi/kg in indicator vegetation, compared to 1313 and 3368 pCi/kg, respectively, in these media from indicator stations during the preoperational period. No fish or invertebrates (river shrimp) were collected during November and December, 1985. Measurements of Cs-137 averaging 97 pCi/kg were recorded by EAS for indicator vegetation during a three-month period in 1984 and once during the preoperational period of 1985 by in-house analysis.
3.3 Comparison of REMP Results with Operational Controls No measureable increases in concentrations of radionuclides or le-vels of radiation in the vicinity of RBS appear to have resulted from plant operation during November and December, 1985. The' indicator ver-sus control comparisons for airborne gross beta activity (Subsection 3.1.1; Table 8) corroborate the reports of no releases of particulates or radiciodine in 1985. Both sets of TLD data (contractor and in-house) demonstrate no appreciable differences in direct radiation exposures between indicator and contro1~ locations during plant operation. The reported liquid release of 0.0127 Ci of tritium with 1.95E8 liters of dilution during November and December, 1985, was not detectable above background in the composited discharge line samples. These findings substantiate the adequacy of source control at River Bend Station.

River Bend Station Docket Number: 50-458 West Feliciana Parish, Louisiana Reporting Period: 1/1/83 - 10/31/85 NOTES:
- 1. Lower Limit of Detection (LLD) as defined in RBS Technical Specifications (NUREG-1172).
- 2. Mean and range based on detectable measurements only. Fraction of detectable measurements at specified locations is indicated in parentheses. (f)
- 3. For each of the TLD locations in 1985, a value equal to 1/3 of its 4th Quarter gamma dose is used to simulate a " quarterly" measurement for October, 1985.
- 4. Beginning in January, 1985, groundwater was sampled from one upgradient (WU - control) and one downgradient (WD - indicator) well; previously groundwater was sampled from construction dewatering wells.
I
- 5. The upstream surface water sampling location (SWU) is used as a " control" for drinking water analyses comparisons.
> 6. The values listed for K-40 were derived from the (then) incipient in-house analytical program.
I
-a
- 7. The values listed for the control location for milk were derived from the (then) incipient in-house analytical program. Training of personnel in calibration and analytical methods delayed sample preparation and counting. As a result, the required LLDs were not met in 2 out of 8 I-131 analyses; 1 out of 9 Cs-134 analyses; I out of 9 Cs-137 analyses; 2 out of 9 Ba-140 analyses; and 4 out of 9 La-140 analyses. Similarly, the required LLD for I-131 in broadleaf vegetation was not met in 1 out of 11 analyses. (See discussion of Program Exceptions in Preoperational Radiological Environmental Monitoring Report for 1985.)

R RIVER BEND STATION RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT FOR 1985 APPENDIX B Interlaboratory Comparison Program Results River Bend Station's offsite contractor laboratory participated in the U. S. Environmental Protection Agency (EPA) Laboratory Intercompari-son Program during 1985. Results of this interlaboratory comparison program are summarized in Table B.1, with error terms based on counting uncertainties at the 2 " sigma" (95 percent confidence) level.
The RBS Environmental Services Group laboratory also participated in the EPA program during 1985. The RBS (in-house) participation code for the intercomparison program is MA, provided here in lieu of a sum-mary.of the limited results, in accordance with the NRC Radiological Branch Technical Position, Revision 1, November 1979.

RIVER BEND STATION RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT FOR.1985 APPENDIX C Summary of Panasonic TLD Results for 1985 At the beginning of January, 1985, Panasonic UD-814 thermolumines - ,
cence dosimeters (TLDs) were co-located with contractor badges'at 44 locations in the vicinity of River Bend Station. This was done in anti-cipation of the eventual replacement of contractor TLDs. The Panasonic badges were deployed and retrieved by the Environmental Services Group, while reading and annealing was performed by the Dosimetry Group of the Plant Staff Radiological Programs Section.
Results of the in-house environmental TLD program are summarized here to augment interpretation of data for the direct radiation exposure pathway and to facilitate comparisons in future annual reports, which will eventually address only Panasonic data.
