J Abstract i
During 1992, a land use census and radiological environmental monitoring 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 93.5 percent of analytical.results within control limits.
i The land use census revealed 2 salient changes in receptor locations since 1991.
Twenty monitoring exceptions occurred out of a total effort' of 1,996 samples t
collected and 2,524 subsequent analyses performed. Seventeen of these exceptions involved ' samples / analyses required by Technical Specification, but none had a significant impact on program quality. Although well below the-required detect ion
- i limits, slightly elevated (relative to baseline data) levels of Cesium-137 ~were
~i sporadically measured in both indicator and control media; these concentrations were I
presumably attributable to the' 1986' incident at Chernobyl, Russia.
The' only l
~
measurable increases in radionuclide activity or levels of radiation above baseline levels'in the vicinity of RBS during 1991, which are attributed to plant ' operation, are the expected low levels in the liquid discharge line. The levels of activity measured in environmental media and in the liquid discharge were below the required levels of detection, and therefore substantially below Technical Specification reporting levels.
Thus the 1992 Radiological Environmental Monitoring Program substantiated the adequacy of source control and effluent monitoring at River Bend
- Station, j

RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT'FOR 1992 i
1.0 INTRODUCTION
i r
This Annual Radiological Environmental Operating-Report for the period'of January 1 through December 31, 1992, is submitted in accordance with Technical l
Specification 6.9.1.7 of Appendix A to River Bend Station License Number NPF-47.
-l River Bend Station (RBS) is a 936 MWe General Electric boiling water reactor located l
in West Feliciana Parish, Louisiana, 4.1 km southeast of St. Francisville (Figure l
1).
Waste heat. from RBS is dissipated via a system using four mechanical-draf t -
i cooling towers which draw makeup water from the Mississippi River, 3.3 (air) km to the west.
Blowdown from the ' cooling tower ' system dilutes low-level liquid l
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, t he ' fuel building
-l exhaust duct, and the radwaste building exhaust duct.
The area within a ' 16-km radius.of RBS includes substantial port ions 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).
j 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 James River Corporation 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).
l i
The area within an 80-km radius of RBS contains all or portions of 19 Louisiana i'
parishes and five Mississippi counties. This area has generally the same makeup 'as i
that of the immediate vicinity of RBS, although wetlands, agricultural lands, and urlan/ improved lands are relatively more extensive (at the expense of forested
[
1.' ?.s) in the southwestern and southeastern quadrants.
Baton Rouge, centered at about 38 km southeast, is the only large city in the general vicinity of RBS.
During 1992, radiological environmental monitoring -in the vicinity af RBS was performed by the Gulf States Utilities Company (GSU) Environmental Services Group with support from the Plant Staff Radiological Programs _ Section in maintain-
~
ing/ calibrating air samplers and in reading / annealing thermoluminescence dosimeters.
2.0 RADIOLOGICAL ENVIRONMENTAL MONITOR _lJG PROGRAM (REMP) l l
2.1 Purpose / Bases The Radiological Environmental Monitoring Program (REMP) was established to provide representative measurements of radiation and of radioactive materials, resulting from RBS operation, in those exposure pathways and for those radionuclides 1

i RIVER BEND STATION RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT FOR 1992 that lead to the highest potential exposures of members of the public.
The REMP implementsSection IV.B.2 of Appendix I of 10CFR50 and thereby supplements the radioactive effluent monitoring program by verifying that the measurable concentra-l tions of radioactive materials and levels of radiation are not higher than expected j
on the basis of the effluent measurements and the modeling of the environmental
.l exposure pathways.
i The REMP applies the concepts of indicator vs. control and preoperational vs.
operational intercomparisons to verify the adequacy of source controls and resultant l
3 human radiation doses. In addition to 10CFR50, Appendix I, 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 Exposure Pathways Elements of the REMP monitor indications of the impacts of gaseous' (airborne) l and liquid effluents released from River Bend Station. The specific methods used l
in monitoring the pathways by'which these effluents could lead to human exposure, l
based on existing demographic information, are:
f HUMAN EXPOSURE PATHWAYS (A)
Airborne Pathway Monitoring Media Immersion Dose (external)
Air Samples (Particulates and Radioiodines) i i
Ingestion Dose (internal)
Vegetation / Food Crop Samples, Air Samples (B)
Direct Exposure Pathway Monitoring Media External Dose Thermoluminescence Dosimetry (TLD) Area Monitors (C)
Waterborne Pathway Monitoring Media Ingestion Dose (internal)
Surface Water Samples Groundwater Sample Drinking Water Samples Fish / Invertebrate Samples Shoreline' Sediment Samples Immersion Dose (external)
Surface Water Samples Shoreline Sediment Samples 4
!l
?
RIVER BEND STATION RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT FOR 1992 I
Site-related dispersion characteristics, demography, hydrology, land
- use, anticipated source terms, and the exposure pathways outlined above were considered l
in the selection of the sample media, sampling and. analysis frequencies, sam-pling/ measurement locations, and types of analyses.
These criteria were used to establish both the preoperational and operational phases of the REMP.
I i
The program that evolved during the preoperational (baseline) monitoring phase i
incorporates all of the elements in the RBS Technical Specifications -(3/4.12.1, 3/4.12.2, 3/4.12.3) plus special study criteria, and is illustrated in Table 1 and l
Figures 1 and 2.
2.3 Land Use Census for 1992 l
The annual land use census, which implementsSection IV.B.3 of Appendix I of j
10CTR50, was conducted during the 1992 growing season in accordance with RBS Technical Specification 3/4.12.2. Table 2 summarizes the results and notes changes-i in nearest receptor locations within 8 km from those identified in the Radiological Environmental Operating Report for 1991.
j The 1992 census identified residences within 8 km of the RBS reactor containment in j
all sectors except L (SW) and M (WSW).
The nearest resident in sector Q (NNW) was i
- 1. 3 km, versus 1.4 km in 1991. The gardens identified in sectors P (WNW) and Q (NW) l are the onsite gardens established 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).
A receptor garden was located in sector E at 2.2 km l
during the 1992 census.
I No dairy animals were found within 8 km of RBS during the 1992 census; milk goats I
were located at 9 km in sector A (N).
Historically, there had never been enough dairy sites to accommodate the minimum RBS Technical Specification requirements for i
analysis of milk, so monitoring of broadleaf vegetation has_ been performed f rom the i
outset.
j GSU began a survey of meat animals within the 8 km radius of RBS during the 1990 census. This initial survey identified beef herds i'n all sectors except L. (SW).
During the 1991 census, meat animals were located in sector L (SW) at 4.6 km.
No changes were observed in the meat animal census during the 1992 census.
I l
2.4 Interlaboratory Comparison Program Results for 1992 l
The Environmental Services Group participated in the U.S.
Environmental Protection Agency (USEPA) Laboratory Intercomparison Program during 1992 in accordance with RBS Technical Specification 3/4.12.3.
RBS results (Table 3) were within the control limits for the,ormalized range (precision) for all analyses, and within the USEPA "known" value (accuracy) for all but ~four analyses.
The discrepancy for these analyses is discussed below.
The USEPA discontinued the cross-check media for " food" in 1989, and although milk sampling and analysis is not 5

(5)
Gross beta analysis not required by RBS Technical Specifications and ODCM.
(6)
Drinking water sampling / analyses not required by RBS Technical Specifications and ODCM.
(No drinking water pathway exista due to extreme distance to nearest-intake).
The upstream surface water sampling location (SWU) is used as a

Preferred species are river shrimp (Macrobracium ohione), blue catfish (Ictalutus furcatus), and freshwater drum ( Anlodinotus gng}niens); if these are unavaliable,.
other edible species may be substituted.
(S)
No irrigation pathway exists due to the extreme distance of nearest domestic water intake (see Note 6)1 let fy vegetables are sampled and analyzed because of limited availability of milk samples.

i required of RBS at this time, the results for the cross-check media for " milk" are
~
included as a gauge for the " food" sample analyses-(i.e., vegetation and fish) performed by RBS.
2.5 Program Exceptions Certain samples and analyses were inadvertently omitted or unavoidably altered
[
during the 1992 operating period, out of a total effort of 1,996 samples collected -
l and 2,524 subsequent analyses performed. These exceptions and the reasons for the omissions / alterations are delineated in Table 4 in accordance with Technical.
l Specification requirements. Corrective ~ actions and impacts on program quality are l
discussed below.
j l
Air Particulates and Radiciodines:
j l
I Twelve program exceptions, with lost of sample / sample volume, occurred involving air particulate and radioiodine sampling. Eight of these exceptions occurred during the i
refueling outage (3 /12/92 to 9/8/92), when the plant was not running. Two of these eight are locat ior, s not required by Technical Specifications (AKS, AHS).
The location AHS also experienced a power outage in January,1992.
Nine of the twelve i
exceptions were due to unknown reasons,.or storm / weather related power outages.
l Three outages were a result of. equipment failures which may have been. weather related.
In spite of the numerous power failures, samples were collected and l
~
analyzed from all locations with adequate volumes to achieve all required detection j
limits with the exception of location AKS (5/19/92 to 5/26/92).
j Direct Radiation (TLD):
i Data for two quarterly and two monthly TLD badges at locations (TAC, TM1) was lost due to vandalism.
Monthly data for two TLD locations (TCS, TD2) was lost due to badges being misplaced and delivered to dosimetry section'too late to be read.
]
The data for the two quarterly TLD locations (TAC.TM1) was replaced with monthly I
data at those locations.
USEPA Cross-check:
During the analysis of potassium in the USEPA milk study of 4/24/92, the activity measured for potassium-40 was incorrectly converted to mass of total patassium.
With the correct conversion applied, RBS would have reported 1,632 mg for total potassium, well within the control limits established for this study.
The results of both the USEPA iodine-in-water study of 2/7/92 and the iodine-in-milk study of 4/24/92 were below the control' limits established for these tests. RBS's investigation determined that an inferior lot of anion exchange resin was used
)
during the analyses of these samples: RBS contacted the resin supplier to resolve I
the problems observed in the I-131 analysis procedure. A fresh I-131 standard _was obtained from EPA to check RBS' preparation / analysis procedures.

resin, were analyzed, yielding the same results as observed with the USEPA milk and l
water studies. All of these results showed percent' recoveries that were 76% to 78%
l of the "known" values. A new batch of resin had been used for the USEPA iodine-in-I water study of 8/17/92; the results of those analyses were all within the control limits of the study. The 1992 surf ace water samples analyzed for I-131 prior to the 8/17/92 cross-check I-131 analysis were re-evaluated using the apparent percent recovery found in the cross-check samples from February and April.

Due to the high results of one sample, a fourth sample was prepared using the I
remaining volume of 54 mis. The salt density (mg/cm ) of the three original samples i
was too high, but was not recognized when the analysis worksheets were reviewed.
t The salt density of the fourth sample was low due to the small amount of volume used, and its result was within the control limits. The results of the four samples were averaged to produce a final result which was'still above the control limits.
The procedure for gross beta sample preparation was changed to note the limitation of sample salt density.

summarized in Table 5. from which measured activities of the naturally-occurring i
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.

RIVER BEND STATION-RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT-FOR 1992 1
3.1.1 Airborne Exposure Pathwav - Measurements of radiciodine and other gamma-emitters were all below their respective LLDs -- that is, " undetectable" at the l
required analytical sensitivities.
Noble gases (Kr-87, Xe-133, Xe-135) were detected in air samples throughout the year.
Cs-137 was measured in charcoal cartridges 9 times at indicator, and 9 times at control locations, presumably traces of Chernobyl fallout.
Gyoss beta activities averaged 0.021 pCi/m' at indicator locations and 0.021 pCi/mL at control locations.
j 3.1.2 Direct Exposure Pathway - The monthly average gamma ray exposures for
~
indicator and control locations were 4.10 and 4.19 millirem (mR) total, respective-ly.
Quarterly exposures averaged 12.4 mR total at indicator' locations and 12.6 mR j
total at control locations.
3.1.3-Waterborne Exposure Pathway - No gamma-emitters were measured in surface water or in drinking water at levels approaching the Technical Specification -
l LLDs. The gamma emitters Mn-54, Co-58, Fe-59, Co-60, Cr-51, Zn-65, Nb-95, and Zr-95 I
were measured in a few monthly composite ~ samples from the CWS discharge line at concentrations between 1.65 and 773 picocuries per liter. Gross beta activities in
]
surface water averaged 144 pCi/1 in the discharge line and from 3 to 10 pCi/1 at all s
other stations. Tritium (H-3) activities in surface water averaged 5594 pCi/1 in i
the discharge line and were below detection limits at all other locations.
Gross i
beta activities averaged 3.0 pCi/1 in the downgradient KD (indicator), and below LLD in upgradient WU (control) groundwater. Besides naturally-occurring gamma emitters -
Cs-137 was measured in Mississippi River shoreline up-stream sediment at 21.8 pCi/kg dry; down-stream at 49.1 pCi/kg dry.
As in the case of the airborne Cs-13e t
activity, this slightly elevated level (relative to baseline conditions) is probably attributable to the 1986 incident at Chernobyl,- Russia.
3.1.4 Ingestion Exposure pathway - Specific activities for radiciodine were below the required LLD in the ingestion pathway monitoring media during 1992.
l Only naturally-occurring gamma emitters was measured in broadleaf vegetation and fish in 1992.
i 3.2 Comparison of Operational and Baseline REMP Results Radiciodine and other gamma emitters 'in the airborne exposure pathway were not measured at levels above the required LLDs dpring 1992.
Gross beta activi, ties on air particulate filters averaged 0.021 pCi/m at igdicator and 0.021 pCi/m' at-control locations ' in 1992, 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 1992 net average readings for monthly and quarterly TLDs from both indicator and control locations were slightly lower than -
the corresponding values for the baseline period. Thus far, no appreciable differ-erences have been observed in TLD exposures between indicator and control locations or between the same locations from one year to the next.

Gross beta activities in the discharge line samples averaged higher in 1992 due to f
the decontamination activities during the fuel outage.
As observed in previous i
years, the annual average gross beta activity for the control location (SEU) j averaged the same as that for the indicator location (SWD). The gross beta activity levels in the discharge line sample (DL) seemingly reflect the normal cycles of l
concentration at which the station cooling towers are operated.
l l
l Tritium activities in the discharge line decreased on average from 1991, reflecting the releases already noted in the 1992 Semiannual Radioactive Effluent Release i
Reports (see also Table 6).
These reduced tritium levels reflect a decrease from l
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 (U-235), 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 The particulates (metals apH-0 I ]).)

In the ingestion exposure pathway, no gamma emitting nuclides were measured above LLDs during 1992, and there appear to have. been no increases 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 3006 pCi/kg in indicator vegetation and at an average of 3871 pCi/kg in control l
veneration in 1992, roughly the same levels encountered prior to RBS operation (refer to Appendix B).
Another natural nuclide, Be-7, averaged 346 and 574 pCi/kg i
in indicator and control vegetation samples, respectively, during 1992.
Although-presumably present, Be-7 was not quantified during the preoperational phase for l
comparison.
l 3.3 Comparison of REMp Results with Operating Controls B
The only measurable increases in concentrations of radionuclides or icvels of j
radiation, attributable to plant operation, in the vicinity of RBS during 1992 l
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; l
Table 5 and Appendix A) corroborate the reports of limited or no releases of part-iculates or radioiodine in 1992.
The 1992 TLD data (Section 3.1.2; Table ' 5 and Appendix A) showed no appreciable differences in direct radiation exposures between indicator and control locations.
Excerpted liquid effluent data from the two i
Semiannual Radioactive Effluent Release Reports are listed in Table 6 along with the l
corresponding Discharge Line analytical data.for those nuclides which were measured i
by the REMp during 1992. These nuclide' activities were well below the NRC reporting l
1evels, but are listed here for comparison to substantiate the adequacy of source control and effluent monitoring at River Bend Station.

For each of the TLD locations in 1955, a value equal to 1/3 of its 4th Quarter gamma dose is used i
to simulate a " quarterly" measurement for october, 1955.

Beginning in January, 1965. groundwater mas sampled from one upgradient (WU - control) and one downgradient (WD - indicator) well; previously groundwater was sampled from construction t
dewatering wells, i
5.
The upstream surface water sampling location (SWU) is used as a " control" for drinking water f
comparisons.
6.
The values 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-I 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 B l-131 l
analyses; 1 out of 9 Cs-134 analyses; 1 out of 9 Cs-137 analyses; 2 out of 9 Ba-140 analyses; and l
4 out of 9 La-140 analyses. Similarly, the required LLD for 1-131 in broadleaf vegetation was not met in 1 out of 11 analyses. (See discussion of Program Exceptions in Preoperational Radiological Environmental Monitoring Report for 1965.)

The LLD for one upstream fish sample flargemouth bass, analyzed in-house) was 263 pCi/kg t wet ).
