- RIVER BEND STATION RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT FOR 1987 Abstract During 1987 a land use census and radiological environmental moni-toring were conducted in the vicinity of River Bend Station (RBS). As part of the monitoring program, the RBS Environmental Services Group participated in an interlaboratory comparison program with slight im-provement (85 versus 81 percent) in performance over the previous year.
The land use census revealed five changes in receptor locations since 1986. Ten monitoring exceptions occurred, of which six involved Techni-cal Specification requirements, although none had a significant impact on program quality. Among several hundreds of analyses, required sensi-tivities (Lower Limits of Detection. LLDs) were not achieved in only three cases. Although well below the required detection limits, slight-ly elevated (relative to baseline data) levels of Cesium-137 were occa-sionally measured in both indicator and control media. These Cs-137 measurements were presumably attributable to the 1986 incident at Cher-nobyl, Russia. The only measurable increases in concentrations of ra-dionuclides or levels of radiation, attributable to plant operation, in the vicinity of RBS during 1987 appear to have been expected low levels in the liquid Discharge Line. These levels were barely above the re-quired LLDs and hence substantially below Technical Specification re-porting levels. Thus the 1987 Radiological Environmental Monitoring Program substantiated the adequacy of source control and effluent moni-toring at River Bend Station.

RIVER BEND STATION RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT FOR 1987
1.0 INTRODUCTION
This Annual Radiological Environmental Operating Report for the period of January 1 through December 31, 1987, is submitted in accor-dance with Technical Specification 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 draf t 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 ef fluents 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 substantial 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 northe ast) . Industrial facilities in the immediate vicinity of RBS are Lambert Redi-Mix Company (1.8 km north-northeast); James River Corpora-tion Paper Mill (5 km south); Big Cajun No. 2 Power Station (5 km south-west); 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.
During 1987, radiological environmental monitoring in the vicinity of RBS was performed by the Gulf States Utilities Company (GSU) Environ-mental Services Group, with support from the Plant Staf f Radiological Programs Section in air sampler maintenance / calibration and reading /
annealing of thermoluminescence dosimeters.

RIVER BEND STATION RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT FOR 1987 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 ex-pected on the basis of the ef fluent measurements and the modeling of the environmental exposure pathways.
The REMP applies the concepts of indicator-control and preopera-tional-operational intercomparisons to verify the adequacy of source controls and resultant human radiation doses. In addition tn 10CFR50, Appendix I, the program is based on guidance provided in the Nuclear Regulatory Commission's Radio!ogical 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 ef fluents 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:
HLMAN EXPOSURE PATHWAYS (A) Airborne Pa thway Monitoring Media Immersion Dose Air Samples (Particulates and Radioiodines)
Ingestion (Internal) Dose Vegetation / Food Crop Samples Air Samples j (B) Direct Exposure Pathway Monitoring Media l
[ Exte rnal Dose Thermoluminescence Dosimetry (TLD) Area Monitors (C) Waterborne Pathway Monitoring Media Ingestion (Internal) Dose Surface Water Samples Groundwater Samples
! Drinking Water Samples l Fish / Invertebrate Samples Shoreline Sediment Samples

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.
The program that evolved during the preoperational (baseline) moni-toring phase, incorporating all of the eierents in the RBS Technical Specifications (3/4.12.1, 3/3.12.2, 3/4.12.3) plus special study cri-teria, is illustrated in Table 1 and Figures 1 and 2.
2.3 Land Use census for 1987 The annual land use census was conducted during the 1987 growing season in accordance with RBS Technical Specification 3/4.12.2. Table 2 summarizes the results and notes changes in nearest receptor locations from those identified in the Radiological Environmental Operating Report for 1986.
As in previous years, the 1987 census identified residences within 8 km of the reactor containment in all sectors except L (SW). Distance to the nearest residence in Sector P (WNW) decreased from 4.5 to 4.2 km.
Distance to the nearest garden in Sector A (N) decreased from 2.0 to 1.8 km. Distance to the nearest garden in Sector E (E) increased from 2.2 to 2.6 km. Cardens identified within 8 km in sectors H (SSE) and M (WSW) in 1986 were found to have been discontinued in 1987. The gardens identified in sectors P (WNW) and Q (NW) are the onsite gardens estab-lished in the sectors with the highest calculated annual average ground-level D/Q. These gardens are REMP indicator locations for broadleaf vegetation (Table 1, Fig. 2).
No dairy animals were found within 8 k: of RBS during the 1987 cen-sus. Historically, there had never been enough dairy sites to accommo-date the minimum RBS Technical Specification requirements for analyses of milk (3 locations within 5 km), so monitoring of broadleaf vegetation has been perforced from the outset.
2.4 Interlaboratory Comparison Program Results for 1987 The Environmental Services Group participated in the U. S. Environ-mental Protection Agency (USEPA) Laboratory Intercomparison Program di r-ing 1987 in accordance with RBS Technical Specification 3/4.12.3. RBE results (Table 3) were near the "known" value, or within the USEPA range of expected laboratory precision for 85 percent of the analyses.

RIVER BEND STATION RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT FOR 1987 RBS analyses of two USEPA cross-check air filter sets over-estimated gross beta activity. The discrepancy seems attributable to the greater thickness of EPA air filter media, resulting in a higher counting efficiency for these filters than for those used in the RBS monitoring program. Gross beta results for water closely agreed with the "known" values, except for that of 4/20/87, which appears attribu-table to technician error.
Results for I-131 in water performed by gamma ray spectroscopy agreed closely for the 4/3/87 cross-check sample, but I-131 activity was underestimated in the 8/7/87 cross-check sample. The latter was concen-trated by evaporation before counting, rather than extracted by ion-exchange, which may have resulted in some loss of radiciodine due to volatilization.
2.5 Program Exceptions Certain samples and analyses were inadvertently omitted or, unavoid-ably altered during the 1987 operating period. These exceptions and the reasons for the omissions / alterations are delineated in Table 4 in ac-cordance with Technical Specification requirements. Corrective actions and impacts on program quality are discussed below.
Power was interrupted to one of the required indicator air samplers (AR1) during part of one week and for all of the following week. A de-fective Ground-Fault-Interrupter receptacle was replaced. Review of meteorological data (Appendix B) indicates that sampler AR1 was downwind of RBS airborne releases from 7.8-8.9 percent of the time in the week of 1/19/87-1/26/87 and from 11.3-15.5 percent of the time in the week of 1/26/87-2/2/87. Considering the relatively short period of potential upwind releases, and that sampler AA1 was continously operating in the adjacent sector, this loss of data is deemed to have had no significant impact on program quality. Storm-related power outages briefly impacted two special interest air samplers ( AB1 and AKS) duriug the summer of 1987, with no appreciable ef fect on program quality.
Two quarterly thermoluminescence dosimeters (TLDs) at the same lo-cation (TR2) were lost due to vandalism and were replaced at the begin-nings of subsequent measurement periods. "TR2" was then moved to a better-camouflaged position at the same range and essentially the same sector azimuth. Inasmuch as four of the six co-located monthly TLDs were successfully retrieved from TR2, the loss of the quarterly badges did not significantly impact program quality.
Slight damage to tubing in the automatic compositing water sampler in the Discharge Line caused each hourly aliquot to be about 5 mis short during the last 8 to 10 hours1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br /> of a 168-hour sampling period. The tubing was repaired, and this incident is deemed to have had no impact on pro-gram quality.

I RIVER BEND STATION RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT FOR 1987 Limited variety in the crops available at the state penitentiary (GQC) during December resulted in failure to obtain one out of 36 re-quired control samples of broadleaf vegetation for 1987. This did not significantly impact program quality.
3.0 INTERPRETATION OF REMP RESULTS 3.1 Summary of Operational REMP Results Monitoring results for the exposure pathways are 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 and treated as indicator stations if they are within 16 km of RBS and control stationa if they are beyond 16 km.
3.1.1 Airborne Exposure Pathway - Measurements of radiciodine and other gamma emitters were all below their respective Lower Limits of De-tection (LLDs) -- that is, "undetectable" at the required ar.alytical sensitivities. Traces of Cs-137 (0.014 pC1/ cubic meter) were measured at Location AHS during the week ending 11/2/87 and again at Location AKS (0.040 pCi/ cubic meter) during the week ending 8/17/87. In the latter case, power to the sampler was interrupted by a thunderstorm af ter only 70 of the normal total of about 400 cubic meters of air were filtered.
In both of these cases, the slightly increased levels of Cs-137 may re-presen t a "legacy" (i.e . , delayed fallou t) from the spring, 1986, inci-dent a t Chernobyl, Russia. Gross beta activities averaged 0.03 pCi/
cubic meter at both indicator and control stations.
3.1.2 Direct Exposure Pathway - The monthly average gamma ray ex-posure for indicator and control locations was 3.43 mR total and 4.03 mR total, respectively. Quarterly exposures averaged 11.83 mR total at in-dicator locations and 11.95 mR total at control locations.
l 3.1.3 Waterborne Exposure Pathway - No gamma emitters were mea-sured in water at levels approaching the Technical Specification LLDs, althou gh Mn-54, Co-58, and Co-60 were measured in a few monthly com-site samples from the Discharge Line at concentrations between 1 and 13 pCi/ liter. Gross beta activities in surface water averaged 21.8 pCi/
l liter in the Discharge Line and nearly 9 pCi/ liter at all other sta-tions. Tritium (H-3) activities in surface water averaged 2650 pCi/
- liter in the Discharge Line and from 1500 to 1700 pCi/ liter at all other locations. Gross beta activities averaged 1.95 and 2.22 pCi/ liter in l the downgradient and upgradient groundwater, respectively. Groundwater i tritium concentrations averaged 1580 pCi/ liter downgradient and 1610 I pCi/ liter upgradient. Besides naturally-occurring gamma emitters, Cs-137 was measured in shoreline sediment from the Mississippi River above (35.7 pCi/kg-dry) and below (54.9 pci/kg-dry) RBS. As in the case of the airborne Cs-137 activities, these slightly elavated levels (rela-I tive to baseline conditions) may be attributable to the Chernobyl inci-dent.

- 3. Monthly gamma exposure estimates are "normalized" to a 30-day month and quarterly gamma exposure 1 estimates are "normalized" to a.90-day quarter.
I 4. Delays in preparing and counting surface water samples for June '1987 were incurred during a program audit and resulted in failure to achieve the required LLDs for I-131. The detection limits achieved for I-131 in the June 1987 surface water samples were 20.2 pCi/ liter for SWU; 15.8 pCi/ liter for SWD; and 26.2 i pCi/ liter for the Discharge Line.

- 5. The upstream surface water sampling location (SWU) is used as a "control" for drinking water comparisons.
- 6. An upstream sediment sampling location, though not required, is used as a "control" for shoreline sediment comparisons. Cesium-137 was detected at both locations during spring and autumn of 1987,
- presumably as a consequence of runoff from areas affected by fallout from the accident at Chernobyl, Russia, in 1986.

RIVER BEND STATION RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT FOR 1987 3.1.4 Ingestion Exposure Pathway - Concentrations of radioiodine were below LLD in the ingestion pathways near RBS during 1987. In addi-tion to naturally-occurring gamma emitters, Cs-137 was measured in both
- fish and broadleaf vegetation from indicator locations, averaging 11.8 pCi/kg-wet (<LLD) in downstream fish and 39.5 pCi/kg-wet (<LLD) in vege-tation from the onsite garden in Sector P. These slightly elevated cor-centrations, which are two orders of magnitude below those that would be "r1 portable" if due to RBS releases, may be attributable to the Cherno- '
. byl incident.
3.2 Comparison of Operational and Baseline REMP Results
'Radioiodine and other gamma emitters in the airborne exposure pathway were not measured at levels above the LLDs during 1987. Gross beta activities on air particulate filters averaged 0.03 pCi/ cubic meter at both indicator and control locations in 1987, as they did during the preoperational phase of the REMP (Appendix A).
In the direct exposure pathway, the 1987 net average readings for monthly and quarterly TLDs from both indicator and control locations were slightly lower than the corresponding values for previous years. ,
Thus far, no appreciable dif ferences have been observed in TLD exposures i be tween indicator and control locations or between the same locations from one year to the next.
In the waterborne exposure pathway, no gamma-emitting nuclides were measured above the RBS Technical Specification LLDs during 1987, as had '
- been the case during the preoperational phase (Appendix A). Gross beta and tritium (H-3) levels in water are compared below:

RIVER BEND STATION RADIOLOGICAL ENVIRONME!!TAL OPERATINC REPORT FOR 1987 WATERBORNE AVERAGE TRITIUM (pCi/ liter)

These slightly increased levels of gross beta activity were well below the reporting levels established in RBS Technical Speci-fications. Moreover, they apparently reflect (at least in part) a slight general increase in levels of beta-emitting materials in the Mississippi River because what may be construed as the "indicator" loca-tion relative to RBS (SWD) had a slightly lower average than the "con-trol" (SWU). Average levels of tritium activity in 1987 vater samples were not appreciably different from those of previous years. It should be noted that Discharge Line monitoring results are based on composites of hourly aliquots of equal volume, rather than on flow-weighted hourly grabs. Although it may be argued that the long-term averages are fairly rcpresentative , it can be seen that the sampling requirement would be truly representative (especially for individual months) only if RBS liquid discharges were continuous at a constant rate, which is not the case (see also the discussion of liquid effluents under Section 3.3 below).
In the ingestion exposure pathway, .to gamma-emitting nuclides were measurcd above LLDs during 1987, and there appear to have been no in-creases in radionuclide concentrations attributable to RBS operations in food / forage media over preoperational levels (Appendix A). Slight in-creases in Cs-137 levels in some fish and broadleaf vegetation samples, presumably related to residues of the Chernobyl accident fallout, were discussed in Section 3.1.4 (above). Naturally occurring K-40 was mea-sured at an average of 3430 pCi/kg-wet in indicator vegetation and at an average of 4080 pCi/kg-wet in control vegetation during 1987, roughly the same levels encountered prior to RBS operation (Appendix A). An-other natural nuclide, Be-7, was measured at 462 and 737 pCi/kg-wet in indicator and control vegetation samples, respectively, during 1987.
Although presumably present, Be-7 was not quantified during the baseline phase for comparison.

RIVER BEND STATION RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT FOR 1987 3.3 Comparison of REMP Results with Operational Controls The only measurable increases in concentrations of radionuclides or levels of radiation, attributable to plant operation, in the vicinity of RBS during 1987 appear to have been the expected low levels in the Dis-charge Line. The indicator versus control comparisons for airborne gross beta activity (Section 3.1.1; Table .5) corroborate the reports of limited or no releases of particulate or radioiodine in 1987. The 1987 environmental TLD data (Section 3.:1.2; Table 5) showed no appreciable differences in direct radiation exposures between indicator and control locations. Excerpted liquid effluent data from the two Semiannual Radi-oactive Ef fluent Release Reports are listed in Table 6 along with the corresponding Discharge Line analytical data for those nuclides which which were measured by the REMP during 1987. These nuclide activities were measured at levels below the Technical Specification LLDs, but are listed here for comparison to substantiate the adequacy of source con-trol and effluent monitoring at River Bend Station.

- 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.
8 y 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.
- 5. The upstream surface water sampling location (SWU) is used in a "control" for drinking water analyses comparisons.
- 6. The values listed for K-40 were derived from the (then) incipient in-house analytical program.
- 7. The values listed for the control location for milk were derived from the ( then) incipient in-house 2
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; i 1 out of 9 Cs-134 analyses
- 1 out of 9 Cs-137 analyses; 2 out of 9 Ba-140 analyses; and 4 out of 9 j 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.)
i .
i l 8. The LLD for one downstream fish sample (catfish, analyzed in-house) was 265 pCi/kg ' (wet) . The LLD
- for one upstream fish sample (largemouth bass, analyzed in-house) was 263 pCi/kg (wet).
