l RIVER BEND STATION RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT FOR 1997 i
i Abstract i During 1997, radiological environmental monitoring and a land use census were conducted in the vicinity of River Bend Station (RBS). As part of the monitoring program, the RBS Radiologica' dnvironmental Monitoring Program (REMP) laboratory participated in a performance evaluation environmental cross-checi program with 96 percent of analytical results within control limits for accuracy and precision. The land use census revealed five changes in receptor locations since 1996. Eleven monitoring exceptions. involving Technical Requirements Manual (TRM) required samples, occurred out of a total effort of 1116 samples collected and 1141 subsequent analyses performed. None of the exceptions had significant impact on program quality. All TRM required lower hmit of detection (LLD) capabilities were achieved in all results except as noted in the monitoring program exceptions. Although well below the required detection limits, slightly elevated (relative to baseline data) levels of Cesium-137 were sporadically measured in both indicator and control media; these concentrations were presumably attributable to the 1986 incident at Chernobyl, Russia The only measurable levels of radiation above baseline levels in the vicinity of RBS during 1997, which are attributed to plant operation, are the expected low levels in the liquid discharge line. The levels of activity measured in the liquid discharge were slightly above required levels of detection, but well below TRM reporting levels. The 1997 Radiological Environmental Monitoring Program thus substantiated the adequacy of source control and effluent monitoring at River Bend Station with no observed impact of plant operations on the environment.

RIVER BEND STATION RADIOLOGICAL ENVIRONMENTAL OPERATING REPORY FOR 'l997 1.0 JNTRQD1LGlLQN This Annual Radiological Environmental Operating Report for the period of January 1 through December 31,1997, is submitted in accordance with Technical Requirements Menual (TR 5.6.2) as required by Technical Specification (5.6.2) of Appendix A to River Bend Station License Number NPF-47.
River Bend Station {RBS) is a 936 MWe General Sectric boiling water reactor located in West Feliciana Parish, Louisiana,4.1 km southeast of St. Francisville (Figure 1). Waste hett from RBS is dissipated via a system using five mechanical draft cooling towra wb:ch draw makeup water from the Miss;r.,sippi River, 3.3 km to the west. Blowdown frorn the cooling tower syster" dilutes low-level liquid radioactiva waste and is discharged to the Mississippi River through a 4.4-km buried pipe located downstream of he intake structure. Gaseous radioactive efLents are released through the main plant exhaust duct, the fuel building ehust duct, and thc radwaste building exhaust duct.
T'ie area within a 16-km radius of RBS ira,ludes substantial porticts of West Feliciana, East Feliciana, and Pointe Coupee parishes as weil as small portions of East and West Baton Rouge parishes. Most of the land in this area is devoted, in at>aut equal proporSons, 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 population centers near RBS are New Roads (10 km southwest) and Jackson (12 km northeast).
Industrial facilities in the immediate vicinity of RBS are Crown Vantage Paper Plant (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 80Am rad,'us of RBS contains all or portice of 19 Louisiana parishes and five Mississippi counties.
This area has generally the same makeup as that of the immediate vichity of RBS, although wetlands, agricultural lands, and urban / improved lands are relatively more extensive in the southwestem and southeastern quadrants. Baton Rouge, centered at about 38 km southeast, is the only large city in the general vicinity of RBS.
DurihD 1997, radiological environmental monitoring in the vicinity of RBS was performed by the River Bend Station Environmental Services Group, a part of the plant Chemistry Depa tment, with support from the plant Radiation Control Department in maintaining / calibrating air samplers. The processing of environmental dosimeters was performed by the Entergy Operations, Inc. (EOI) Central TLD Processing Facility located at Waterford Three (W3).
2,0 RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM (REMP) 2.1 Purcose/HaSes The Radiologica! Environmer.tal Monitoring Program (REMP) was established to provide representative measurements of radiation and of radioactive materials, res.iting from RBS operation, in those exposure pathways and for those radionuclides that lead to the highest potential exposures of members of the public.

i RIVER BEND STATION RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT FOR 1997 The REMP implementsSection IV.B.2 of Appendix ! of 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 expected on the basis of the effluent measurements and the modeling of the environmental exposure pathways.
The REMP applies the concepts of indicator vs. control and preoperational vs. operational comparisons to venfy the adequacy of source controls and resultant human radiation doses. In addition to 10CFR50, Appendix 1, the program is based on guidance provided in the Nuclear Regulatory Commission's Radiological Branch Technical Position, Revision 1, November 1979, as well as NRC Regulatory Guides 4.1 and 4.15.
2.2 Environmental Radiation Exoosure 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 effluents could lead to human enposure, based on existing demographic information, are:
HUMAN EXPOSURE PATHWAYS (A) Airborne Pathway Monitoring Media Inhalation Dose (internal) Air Samples (Particulates and Radioiodines)
Ground Plane Dose (external) Thermoluminescence Dosimetry (TLD)
Immersion Dose (external) Thermoluminescence Dosimetry (TLD)
Ingestion Dose (internal) Vegetation / Food Crop Samples (B) Direct Exoosure Pathway Monitoring Media External Dose Thermoluminescence Dosimetry (TLD)
(C) Walefoorne Pathway Monitoring Media ingestion Dose (internal) Surface Water Samples Groundwater Samples Fish / Invertebrate Samples Shoreline Sediment Samples immersion Dose (external) 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 analyses. These criteria were used to establish both the preoperational and operational phases of the REMP.

! RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT FOR 1997 The program that evolved during the preoperational (baseline) monitoring phase incorporated all of the elements in the RBS Technical Specifications (3/4.12.1, 3/4.12.2, 3/4.12.3), now contained in the RBS Technical Requirements Manual, including special study criteria, and is illustrated in Table 1 and Figures 1 and 2.
2.3 Land Use Census for 1997 The annual land use census, which implementsSection IV.B.3 of Appendix I of 10CFR50, was conducted during the 1997 growing season in accordance with RBS Technical Requirements Manual (TR 3.12.2). Table 2 summarizes the results and notes changes in nearest receptor locations within 8 km from those identified in the Radiological Environmental Operating Report for 1996. The annual land use census did mi identify any location (s) that yields a calculated dose or dose commitment greater than the values currently being calculated in requirement TSR 3.11.2.3.1.
The 1997 census identified residences within 8 km of the RBS reactor containment in all sectors except M (WSW) and N (W). The five changes in the 1997 census involved nearer residents in sectors F and O. The nearest resident in sector F (ESE) was 2.1 km, compared to 3.5 km in 1996; and the nearest resident in sector O (NW) was 1.3 km, compared to 1.4 km in 1996. A further resident at 1.9 km, compared to 1.8 km, was identified in sector J (S). A resident at 7.9 km was found in sector L (SW) compared to none in 1996. No resident was found in sector N (W) within 8 km compared to one resident at 6.1 km in 1996. Sector N (W) is also the highest ground-level D/O sector.
No dairy animals were found within 8 km of RBS during the 1997 census. Historically, there have never been enough dairy sites to accommodate the minimum RBS Technical Specification requirements for analysis of milk, so monitoring of broadleaf vegetation has been performed from onsite gardens.
The garden census was discontinued in 1996, due to the note in the TRM (TRCO 3.12.2) that allows the routine sampling of broadleaf vegetation in two different sectors near site boundary in lieu of the annual garden census. Two site gardens have been maintained in sectors P (WNW) and O (NW) for fourteen years, and a third garden was located in sector N (W) in December of 1996, although samples were mi available from this garden until July of 1997.
2.4 Environmental Cross-Check Program Results for 1997 The RBS REMP Laboratory participated in an approved performance evaluation cross-check study program during 1997 in accordance with RBS Technical Requirements Manual (TR 3.12.3). RBS results (Table 3) were within the control lirnits for the normalized range (precision) for all analyses, and within the "known" value (accuracy) for all but eight nuclide analyses. The discrepancy for these analyses is discussed below.
The United States Environmental Protection Agency (USEPA) discontinued providing cross-check sample media to NRC licensees in December of 1995. RBS began purchasing environmental cross-check samples from Analytics, Inc.
(NRC approved program) in January of 1996. The statistical calculations provided by the USEPA in their study reports have been adopted and continued by RBS as acceptance enteria in evaluating the results of the cross-check samples provided by Analytics, Inc. Acceptance criteria (as used by Analytics for demonstrating tracability with NIST) for evaluating results have been recommended by Analytics, Inc., and are under consideration by RBS and others for future use.
There were eight results out of control limits (3 sigma) for accuracy in the 1997 c oss-check program. Of these l eight out of control limit results, all were analyzed by gamma spectroscopy (6 rnclidt s in two matricos). Five of the l results in question were in liquid cross-check samples, three in the sediment Famples 5
I
RIVER BEND STATION RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT FOR 1997 .
1 There was a single result for Mn-54 in water out of control limits. Review of the cross-check results for the year indicated a high bias for Fe-59 and Cs-137 in water, even though there were only two instances each out of control limits. Investigation of this bias indicated it was due to coincidence summing effects of Y-88 and Co-60 on the efficiency curve in the effected region. To minimize the coincidence summing effects on the efficiency curve in the energy region in question, RBS will add two additional nuclides (Mn-54 and Zn-65) to the next set of liquid calibration sources purchased. The addition of these nuclides to the calibration source should bring the results for the three nuclides in question within control limits.
Review of the three out of control limit results in the sediment samples did not indicate a trend or bias. Given the limited data for sediment cross-check samples (4 samples) to date, it was not possible to establish a trend. The three out of control limit results were each for a different nuclide (Cr-51, Cs-134, and Ce-141). No corrective action due to these results will be taken at this time. If, after collection of additional data, a trend or bias is established, corrective action will be taken at that time.
There is no impact on past data indicated by these cross-check program exceptions. Environmental samples are analyzed and reported with a 95% confidence level that the analytical result with its associated error encompasses the "true' value. As seen in Figure 3 (page 18) for 1997, 96% of the RBS environmental cross-check results were within control limits for accuracy and precision..
2.5 Monitoring Program Exceotions Certain samples and analyses were unavoidably omitted or altered during the 1997 operating period, out of a total effort of 1116 samples collected and/or prepared, and 1141 subsequent analyses performed. These exceptions and the reasons for the omissions / alterations are delineated in Table 4 in accordance with Technical Specification requirements. As allowed by RBS TRM, deviations are permitted from the required sampling schedule if samples are unobtainable due to legitimate reasons. Corrective actions and impacts on program quality are discussed starting t,elow Air Particulates and Radiciodines Eight program exceptions, with loss of sample or sample volume, occurred involving air particulate and radioiodine sampling. All were caused by power outages due to weather, equipment malfunctions, or malfun&n of sampling equipment. In spite of the power failures or equipment malfunctions, samples were collected and annyzed from all locations with adequate volumes to achieve all TRM required detection limits (LLD) with the exception of location AP1 (WNW) and AOi (NW), indicator locations at site boundary. The entire volume at location AP1 was Ic st for the period 4/28/97 to 5/5/97 due to a pump failure. The next sampling period for this same location suffered a SS% loss of sample volume due to the lack of availability of a spare cahbrated air sampler. The air sampler was replaced on 5/9/97. The joint frequency report indicated only 1.7% winds from the opposite sector for the entire period of 4/28/97 to 5/9/97.
Winds during the outage period were mainly from the south to the north where location AA1 (N) indicated nothing.
Location AQ1 (NW) suffered 100% loss of sample volume the first week of 1997 due to the failure of an air sampler.
The sampler was replaced the same day it was found inoperative. The joint frequency report indicated only 4.9% winds from the opposite sector.
RBS is currently using methods for determining more precisely when, during the week-long sample period, power outages or equipment failures occur so that comparison with wind direction joint frequencies or windrose will document the extent to which required sampling was achieved. Recorders are used at sampling locations to chart actual hours of power outages as they occur.
Direct Radiation (TLD) l i
Data for the second quarter at location TEC (E) was lost when the TLD badge was found missing during quarterly collection. TEC is a control location, but two other control locations exist to supply control data. The loss of TLD i badges is a common occurrence when deploying TLD's in 40 locations over five parishes. This was the first occurance j of vandalism at this remote location; further occurances will necessrtate the relocation of this station. i 6

NOTES:
(1) For purposes of data summary, comparisons, and discussion, the sampling locations designated as "Special Interest" are treated as indicator stations, except location TGS, due to distance from site.
(2) Sample / measurement location not required by RBS Technical Requirements Manual.
(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) Drinking water sampling / analyses not required by RBS Technical Requirements Manual and ODCM. No drinking water pathway exists due to extreme distance to nearest intake.
(5) Preferred species are river shrimp (Macrobracium ohione), blue catfish (letalurus furcatus), and freshwater drum (Actodinotus gu,lDDieDs); if these are unavailable, other edible species may be substituted.
I (6) No irrigation pathway exists due to the extreme distance of nearest domestic water intake ; leafy )

RIVER BEND STATION RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT FOR 1997 Yggetation Samoles Due to the inclement weather and hard freezes experienced during December of 1996 and into the first four months of 1997, the vegetation sample collections were inadequate from one onsite indicator garden in sector P (WNW). The TRM Table 3.12.1-1 indicates sampling and collection frequency as " Monthly during the growing season". Adequate vegetation was obtained from the other onsite garden in sector Q (NW).
Duplicate vegetation samples have been provided monthly to the Louisiana Department of Environmental Quality (DEO), as a courtesy, from the onsite gardens. In June of 1997, only two of three samples collected from each garden (G1 and G2) were analyzed by RBS; the third sample from each garden was transferred to the DEQ rather than the duplicate samples usually supplied. As a result, analysis results were obtained and reviewed from the DEQ laboratory.
Also the collection of vegetation for DEO will be included in the collection procedure and a collection sheet will be used to log the samples.
A new garden location was established in sector N (W) in January of 1997, and sample collections began in July.
All three gardens will remain in cultivation until July of 1998, so baseline data can be established in the new location.
After sufficient data has been collected, a comparison of data from the new location (sector N) versus data from the old locations (sectors P and Q) will be performed to access impact, if any, as to the incorrect siting of the onsite garden.

RIVER BEND STATION RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT FOR 1997 3.0 INTERPRETATION OF REMP RESULTS 3.1 Summarv of Ooerational REMP Results Monitoring results for the exposure pathways are itemized in Appendix A and summarized in Table 5, from which measured activities of the naturally-occurring daughters of uranium and thorium are excluded. For purposes of data summary, comparison, and discussion, the sampling locations designated "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 Exoosure Pathway - Measurements of radiciodine and other gamma-emitters (Cs-134, Cs-137) were all below their respective LLDs -- that is, " undetectable" at the required analytical sensitivities. Gross beta activities on air particulate filter residues averaged 0.024 pCi/m' at indicator locations, and 0.029 pCi/m' at control locations.
3.1.2 Direct Exoosure Pathway - Quarterly exposures averaged 13.84 mR total at indicator locations and 14.00 mR total at C9attpl locations normalized over a ninety day period. Exposures measured in 1997 were slightly lower than the previous year. Little difference is noticed between exposure averages ofindicator and controllocations.
3.1.3 Waterborne Exoosure Pathway - No gamma-emitters were measured in surface waters (up and down stream) or groundwater ( up and down gradient) during 1997. All measurements in surface waters and groundwaters were below their respective LLDs. A Cs-137 peak was quantifieo at 42.7 pCi/kg in an up-stream river sediment; all other results were below their respective LLDs. The gamma emitters Mn-54 and Co-60 were measured in five monthly composite samples from the CWS discharge line at concentrations between 6.62 and 15.3 pCi/l. Tritium (H-3) activities averaged 2063 pCi/l in the discharge line and were below detection limits at all other locations. The reduction of liquid radwaste discharges during the first quarter of 1996 has decreased the amount of low-level activity usually measured in the discharge line monthly composites. Naturally-occurring gamma-emitters, such as K-40, were measured in Mississippi River shoreline up-stream and down-stream sediments.
3.1.4 Ingestion Exoosure Pathway - TRM required nuclides were all below the required LLD in the ingestion pathway monitoring media consisting of vegetation and fish during 1997. Only naturally-occurring gamma-emitters, such as K-40 and Be-7, were measured in fish and vegetation samples.

RIVER BEND STATION RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT FOR 1997 3.2Comoarison of Ooerational and Baseline REMP Results Radioiodine and other gamma-emitters in the airborne exposure pathway were not measured at levels above the required LLDs during 1997. Gross beta activities on air particulate filters averaged 0.024 pCi/m at indicator and 0.029 pCi/m' at control locations in 1997, compared to 0.03 pCi/m' at both indicator and control locations during the preoperational phase of the REMP (Appendix B).
In the direct exposure pathway, the 1997 net average normalized readings for quarterly TLDs from both indicator and controllocations were slightly lower than the corresponding values for the baseline period. Thus far, no appreciable differences have been observed in TLD exposures between indicator and control locations or between the same locations from one year to the next.
In the waterborne exposure pathway, activities for required gamma-emitting nuclides were measured at levels below the RBS Technical Requirements Manual LLDs during 1997 as had been the case during the preoperational phase (Appendix B), except in the CWS discharge line. The low-level activity usually measured in the discharge line monthly composites decreased in 1996 due to the reduction in frequency of liquid radwaste discharges. As in !
preoperational period, required gamma-emitting nuclides in shoreline sediments were all below LLDs; although a Cs-137 peak,42.7 pCi/kg (below LLD of 180 pCi/kg), was measured in an up-steam sediment. Naturally-occurring K-40 averaged 13,735 pCi/kg in indicator and 11,615 pCi/kg in control samples in 1997; approximately the same as measured during preoperational period. Tritium levels in water are compared below:

These tntium levels reflect a decrease from 1990 due to removal of failed fuel, but represent an increase compared to years prior to 1990, due to more efficient radioactive wastewater treatment and reuse (e g., boiler makeup). In the RBS boiler-reactor, tritium is produced by ternary fission of the reactor fuel (2ssU), although only a small fraction of that tritium would diffuse through the fuel's cladding. Tritium is also produced by neutron reactions with certain isotopes of boron, deuterium and lithium when present in the boiler (e g. as control rod material - boron). The particulates (metals and salts) are removed in radioactive wastewater treatment leaving the tritium behind as water (e g., [ H-O 'H]). When this water is reused as boiler makeup, the tntium concentration in the water increases. During the first quarter of 1996 the number of liquid radwaste discharges were decreased significantly, due to improved treatment process for TOC removal, .
allowing recycle of liquid radwaste to the condensate storage tank for reuse. This reduction in radwaste discharges I has decreased the amount of tritium and gamma-emitting nuclides measured in discharge line monthly composites.
In the ingestion exposure pathway, no gamma-emitting nuclides were measured above LLDs dunng 1997. There appears to have been no increase in radionuclide concentrations attributable to RBS operation in food / forage media over baseline levels (Appendix B). Naturally-occurring K-40 was measured at an average of 3294 pCi/kg in indicator vegetation and at an average of 3165 pCi/kg in control vegetation in 1997, roughly the same levels encountered prior to RBS operation (Appendix B). Another natural nuclide, Be-7, averaged 978 and 725 pCi/kg in indicator and control vegetation samples, respectively, during 1997. Although presumably present, Be-7 was not quantified during the preoperational phase for comparison.

RIVER BEND STATION RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT FOR 1997 3.3 Comoarison of REMP Results with Ooerational Controls The only measurable concentrations of radionuclides, or levels of radiation above normal environmental background, attributable to plant operation, in the vicinity of RBS during 1997 appear to have been the expected low levels in the liquid discharge line. The indicator vs. control comparisons for airborne gross beta activity (Section 3.1.1; Table 5 ,
and Appendix A) corroborate the reports of limited or no releases of particulates or radiciodine in 1997. The 1997 l TLD data (Section 3.1.2; Table 5 and Appendix A) showed no appreciable differences in direct radiation exposures between indicator and controllocations. Excerpted liquid effluent data from the Annual Radioactive Effluent Release Report (1.21) are listed in Table 6 along with the corresponding Discharge Line analytical data for those nuclides which were measured by the REMP during 1997. Comparisons for 1997 are not as favorable as past years due to the reduction in frequency of radwaste discharges. These nuclide activities were well below the NRC reporting levels, but are listed here for comparison to substantiate the adequacy of source control and effluent monitoring at River Bend Station. A graphical comparison of the 1.21 report data and the REMP results for tritium activities over the past years is illustrated in Figure 4, page 27.

r (1) Lower Limit of Detection (LLD) as de ined in RBS Technical Specifications (NUREG-1172), now TRM (2) Mean and range based on detectable measurements only. The 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 one-third of its 4th Quarter gamma exposure is used to simulate a "quarterty" rneasurement for October,1985.
(4) Beginning in January,1985, groundwater was sampled from one upgradient (WU - control) and one downgradent (WD - indicator) well; previously, groundwater was sampled from construction dewatenng (well-point) wells.
(5) The upt,tream surface water sampling location CVAf is used as a " control" for drinking water comparisons.
(6) The values hsted for K-40 were derived from the i,atialin-house analytical program.
(7) The values listed for the control location for milk were denved from the initial 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 (by the in-house analytical program during this training period)in 2 out of 8 l-131 analyses: 1 out of 9 Cs-134 analyses; 1 out of 9 of 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 the Preoperational Radiological Environmental Monitoring Report for 1985.)
(8) The LtD for one downstream fish sample (catfish, analyzed in-house) was 265 pCi/kg (wet). The LLD for one upstream fish sample j (largemouth bass, analyzed in-house) was 263 pCi/kg (wet). !
