RIVER' BEND STATION RADIOLOGICAL ENVIRONMENTAL OPERATING rep 0RT FOR 1991 Aksiraqi During 1991, a land use census and radiological environmental monitoring were conducted in the vicinity of River Bend Station (RBS). As pait of the monitoring program, the RBS Environmental Services Group participated in an interlaboratory comparison program with 97.5 percent of analytical results within control limits. lne land use census revealed 5 salient changes in receptor locations since 1990. Twelve monitoring exceptions occurred out of a total effort of 1,996 samples collected and 2,488 subsequent analyses 4
performed. Nine of these exceptions involved Technical Specification requirements, but none had significant impact on pregram quality. Although well below the required detection limits, slightly elevated (r '2tive 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 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 1991 Radiological Environmental Monitoring Program substantiated the adequacy of source control and ef fluent monitoring at River Bend Station.

RIVER BEND STATION RADISLQQLQAL ENVIRONMENTAL OPERATING REPORT FOR 1991 s
1.0- LERODUCTION This Annual' Radiological Environmental Operating Report for the period of-January 1 through December 31, 1991, is submitted in accordance 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 southeast of=St. Francisville (Figure 1).; Waste heat from RBS is dissipated via a system using four mechanical draf t cooling towers which draw makeup water f rom the Mississippi River, 3.3 (air) km to the west.- Blowdown from the cooling tever 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 duet, 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 nor thwes t ),
human population centers near RBS are New Roads (10 km southwest) and Jackson (12 km northeast). Industrial f acilities in the immediate vicinity of RBS are Lambert
..Redi-Mix. Company (1.8-km north-northeast); James River Corporation Paper _ Mill (5 km south); Big Cajun No. 2 Power Station-(5 km southwest); and the Corps of-Engi-neers concrete casting yard (5 km west).
The area within an 80-km radius of RBS contains all or portions of 19 Loul-siana_ parishes-and.five Mississippi counties. This area has generally the-same makeup as that-of the imnediate vicinity of RBS, although wetlands, agricultural
, lands, and . urban / improved lands are relatively more extensive (at the _ expense of forested lands) 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 1991i radiological environmental monitoring in the vicinity of RBS was performed by the Gulf States titilities Company (GSU) Environmental Services Group with support ' f rom the Plant Staff Radiological Programs Section in maintain-ing/ calibrating air samplers and in reading / annealing thermoluminescence dosimeters, l-c i.

= The Radiological Environmental Monitoring Program (RDfP) was established to provide representative measurements of radiation and of radioactive materials, resulting f rom RBS operation,'in those exposure pathways and for those radionuclides that lead to the highest potential exposures of members of the public. The REMP implementsSection IV.B.2 of Appendix I of 100FR50 and thereby supplements the radioactive effluent monitoring program by verifying that_ the measurable concentra-tions 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 applles - the concepts of ' indicator vs. control and preoperational vs. operational intercomparisons to verify the adequacy of source controls and resultant human-radiation doses. In addition to 10CFR50, Appendix I, the program
_is' based >on guidance provided in the Nuclear Regulatory Commiw on's Radiological Branch Technical Position, Revision 1, November 1979, as well as NRC Regulatory
-Guides 4.1 and 4'.15.
2.2- . Etnvironmental flajiiation l Exp_qsure 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 exposure, based on existing- deraographic information, are:

Ingestion Dose (internal) Surface Water Samples Groundwater Sample Drinking Water Samples l'ish/ 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, sam-
- pling/ measurement locations, and types of analyses. These criteria were used to establish both the preoperational and operational phases of the REMP.
The-program that evolved .during the preoperational (baseline) monitoring phase 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 c-iteria, and is illustrated in Table =1_-and_ Figures 1 and 2.
2.3- LialnLVse Census- for 1991
- The annual land use census, which implements Sectiol IV.B.3 of Appendix 1 of
-10CFR50,_ was conducted 'during the 1991 growing-season in accordance with RBS
~ Technical Specification 3/4.12.2. 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 1990.
The 1991. censusi identified residences within 8 ~ km of the ' RBS reactor
~ containment'in'all sectors except L (SW) and M (WSW). The-nearest resident in sector P (WNW) was at 3.5 km-in 1991 versus 3.7 km in- 1990. The nearest resident'in sector Q (NNW)' was 1.4 km, versus 1.3 km Lin 1990. The gardens . identified in sectors P (WNW)-and Q (NW) are-the onsite gardens established in the sectors with the highest
- calculated - annual average ground level D/Q, These g ardens' are REMP ' indicator
, locations for-broadleaf vegetation (Table _1, Fig. 2).
No dairy animals were found- within-8 km of RBS during the 1991 census;- ' milk goats were located at _9 km in ' sector A (N). Historically. there had never.been enough -dairy - sites. to acconnodate the minimum RBS Technical Specifleation requirements for. analysis of milk, so monitoring-of broadleaf vegetation has been
-performed from the_ outset.
GSU began-a survey of-meat animals within the 8 km radius of RBS during the
- 1990-census. This initial survey identified beef herds in all sectors except L (SW). During the 1991 census, meat animals were-located in sector L (SW) at 4.6 km. Other changes in 1991 include meat animals in sector A- (N) -at 3.0 km versus 1.9 km in 1990, and in sector R (NNW) at 3.0 km versus 2.4 km in 1990.

4 2.4 lItttflaIt0L#10Ly.30tnPM.1191LPIQtLaptRetuttjlLigr 19jL1 The Environmental Services Group participated in the U.S. Environmental Pro-tection Agency (USEPA) Laboratory Intercoruparison Program during 1991 in accord-ance with RBS Technical Specification 3/4.12.3. RBS results (Table 3) were within the control limits for the normalized range (precision) for all analyses, and within the USEPA "known" value (accuracy) for all but one analysis. s.amely, the gross beta in air filters (3/29/91). The discrepancy for the gross beta in air filter s is discussed below. The t'SEPA discontinued the cross-check media for " food" in 1989, and although milk sampiing and analysis is not required of RBS at this time, the -
results for the cross-check ruedia for " milk" are included as a gauge f or t he " food" sample analyses (i.e., vegetation and fish) performed by RBS.
2.5 f.rptWLEErptlons '
Certain samples and analyses were inadvertently omitted or unavoidably altered during t he 1991 operating period, out of a total ef fort of 1,996 samples collected and 2,488 subsequent analyses performed. These exceptions and the reasons for the omissions / alterations _ are delineated in Table 4 in accordance with Technical Specification requirements. Corrective actions and impacts on program quality are discussed below.
Ai r_Pa t11c ulaat s. . endAdip10111nthi Calibration records for two' air samplers showed one sampler's deployment flow rate as 45 liters per minute and the other sampler's flow rate as 70 liters per minute.
Both had been issued as calibrated to the 40-45 liter per minute range usually used -
for environmental sampling. The flow rates measured upon retrieval showed both flow rates as 70 litet. Per n.inute. In both cases, the analyses performed were conservative since larger air sample volumes were collected and counted than was used in the calculation of results. The required limits of detection for I-131, Cs-134 & Cs-137 were met when using total volumes based on the 40-45 liter per minute certification, and therefore wovld be met if volumes based on a 70 liter per minute certification were used in the calculations. i Brief storm-related power outages impacted one indicator air sampler (AA1) in November and December, and two control samplers (AHS, AGS) in October and November.
~ From 8 percent to 8b percent of each of the expected sample volumes was lost due to the power outages, or associated equipment malfunctions. At one control
~ location,'AGS, the require.d detection limit for 1-131 was not achieved due to insufficient air sample volume having been collected. During the period 10/28/91 to '11/4/91, the indicator sampler (AA1) missed 65% of the week-long sample, but was ,
dwnwind of RBS airborne releases (according to the wind direction . joint f requen- '
cles) only 5% of this period. During the period 11/25/91 to 11/2/91, this same sampler missed 8% of the week-long sample, but was downwind of RBS airborne releases (per . joint frequer>cles) for 49% of this period. Although the samplers at_AGS and AHS were occasionally downwind of RBS, they are too far from RBS to collect plant ,

USE" Alt 9stchtek_ _.9195s_Jit:!a ortAiLIllt ets Gross beta analysis for the 3/29/91 USEPA cross-check air filters exceeded the control limits f or accuracy. The above-control-limit result is thought to be caused by the :lif f erence in counting ef ficiency result inn f rom the distribution of activit y on the surf ace of the much thicker EPA filter. The gross beta activity analysis on RBS air filter samples uses a gas-flow pr oportional detector. The air filter calibration standati used by RBS is prepar ed on a glass fiber filtnr by the supplier to emulate the uniform distribution of source material across the f ace of a typical air filter sample. The USEPA's cross-check air filter is prepar ed hv deposit tog the "known" amount of activity (source material) on the surf ace of a styrofoam wafer. This styrofoam wafer is much thicker than the glass f iber filter rnedia used by RBS for air sampling, thereby positioning the activity of the simulated air f11ter closer to the counting instrument 's detector when this water is processed as an air satople. Thi+ results in a higher count rate for the cross-check sample's activity than would result from the same activity on a g' ass fiber tilter. To reduce. RBS's high bias for accuracy on air filters within the USEPA cr oss-chcak program. a special sample holder has been devined to position the surface of the cross-check air filter sample at the same distance from the detector as that distance used for air filter samples.

_ PAD 10MLGKALEND ROMifXTALJPERATING JEP.0RLTSB 1991 3.1.1 Airbotpelposur e_ Pat.hkay - Measurement s of radioiodine and othen gamnia-emitt ers were all below their respect ive LLDs -- t hat is, "undet ectable" at the required analyt ical sensitivities. Noble gases (Kr-87, Xe-133, Xe-135) were detected in air sainpl es throughout the year. Cs-137 was measured in charcoal cartridges 8 times at indicator, and 4 t imes at control locat ions, presumably traces of Chernobyl fallout. Gross beta activities aver aged 0.020 pC1/m3 at indicator locations and 0.019 pCi/m 3 at control locations.
3.1.2 DiIect EsposutilatJmiy - The mont hly average gamma r av expcsur es ~
for indicator and control locations were 4.28 and 4.46 millitem (mR) total, r- cectively. Quarterly exposures averaged 12.39 mR total at indicator locations and 12.69 mR total at control locatiors.
3.1.3 Wit tath9tDr_Elpohute_.Palhway - No gamma-emitters were measured in surf ace water or in drinking water at levels apptoaching the Technical Specification LLDs. The gamma emitters Mn-56, Co-58, Fe c and Co-60 were measured in a few monthly composite samples from the CWS disc. rge line at concentrations between n.46 and 27.4 picocuries per liter. Grocs beta activities in surf ace water aver aged aa.9 pC1/1 in the discharge line and from 3 to 8 pCi/l at all other stations.
Tritina :; ~3) activities in surf ace water averaged 7,047 pC1/1 in the discharge line and were below detection limits at all other locations. Gross beta activities averaged 3.2 pCi/l in the downgradient WD (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 147 pCi/kg dry. As in the case of the airborne Cs-137 activity, this slightly elevated level (relative to baseline conditions) is probably attributable to the 1986 incident at Cher nobyl, Russia.
3.1.4 Lnzelll0Dl3nosure Pathway - Specif2 activities for radioiodine were below the required LLD in the ingestion pathway monitoring media during 1991.
In addition to naturally-occurring gamma emitters, Cs-137 was measured in broadleat vegetation from one indicator location. The Cs-137 averaged 20.4 pCi/kg wet (<LI.D) in vegetation from the onsite garden in Sector P (G1). No C1-137 was measured in fish samples. Cobalt-60 at 16.1 pCi/kg wet was measured in one sample of downstr eam fish. These slightly elevated Cs-137 activities, which are two orders of magnitude below those that would be " reportable" if due to RBS releases, are piobably attributable to Chernobyl f allout. The Co-60 activity in the downst ream fish sample is presumed to be from the station discharge line, and is three orders at magnitude below the level that would be reportable.
3.2 Cnmpar isojLgf 0netAtigna_LandJa:Leling_RFMP_PasnLtjt Radiciodine and other gamma emitters in the airborne exposure pathway were not measured at levels above the required LLDs during 1991. Gross beta activities on air particulate filters averaged 0.020 pCi/m' at indicator and 0.019 pCi/m' at control locations in 1991, compared to 0.03 pCi/m 3 at both indicator and control locations during the preoperational phase of the REMP (Appendix B).

'In the direct exposure pathway, the 1991 net average readings for monthly and quarterly TLDs f rom both indicatot and control locations were slightly lower than the corresponding values for the baseline period. Thus far, no appreciable dif fer-erences 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, average activities analyzed for required gamma-emitting nuclides were measured below the RBS Technical Specification I.LDs during 1991 as had been the case during the preoperational phase (Appendix B).
Gross beta and tritium levels in water are' compared below:

. the same or slightly lower in 1991 than in previous years. As obst in previous years, the annual average gross beta activity for the control ation (SRU) averaged the same as that for the indicator location (SWD). The gross neta activity J levels in the discharge line sample (DL) seemingly reflect the normal cycles of concentration at which the station cooling towers are operated.
Tritium activities in the discharge line decreased on average from 1990 reflecting the releases already noted in the 1991 Semiannual Radioactive Effluent Release Reports _(see also Table 6). These reduced tritiut- levels reflect a decrease from 1990 due to removal of f ailed fuel, but represent an . icrease 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 (235U), 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) 21

_ R.Al!LQLO3LCAllNylRQMIMIALJfGATIMJLP@il_lQlt 1991 are removed in this treatment leaving the tritium behind as water (e.g., (311 1111). When this water is reused as boiler makeup, the tritium concentration in the water increases.
In the ingestion exposure pat hway, no gamma emittina nuclides were measured above LLDs during 1991, and there appear to have been no increases in radionuctine concentrations at tributabl e to RBS operation in food / forage media over baseline levels (Appendix B). Slight increases in Cs-137 levels in some bioadleaf vegetation samples, presumably related to residues of the Chernobyl accident fall- ~
out, were discussed in Section 3.1.4 (above). Naturally-occur ring K-40 was measured at an average of 2,947 pCi/kg in indicator vegetation and at an average of 4,335 pCi/kg in control vegetation in 1991, roughly the same levels encountered prior t o RBS operation (Appendix B). Another natural nuclide, Be-7, averaged 327 and 479 pCi/kg in indicator and control vegetation samples, respectively, during 1991.
Although presumably present, Be-7 was not quantified during the preoperational phase for comparison.
6 3.3 Compari19n_sLERiP_Essult.s wi.th_0 f er;aLLozlont roh The only measurable increases in concentrations of radionuclides or levels of radiation, attributable to plant operation, in the vicinity of RBS during 1991 appear to have been the expected low levels in the liqoid 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 part-iculates or radioiodine in 1991. The 1991 TLD data (Section 3.1.2; Table 5 and Appendix A) showed no appreciable dif ferences in direct radiation exposures between indicator and control locations. Excerpted liquid ef fluent data from the two Semiannual Radioactive Effluent Release Reports are listed in Table 6 along with the corresponding Discharge Line analytical data for those nuclides which were measured by the REMP during 1991. These nuclide act ivitics were wi 11 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.

- 5. The upstream surface water easpling location (SWU) is used as a ." control'* for drinking water comparisons.
- 6. The values for K-40 e 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 analytical program. Tratning of personnel in calibration and analytical methods delayed sample preparati sn and counting. .As a result, the required LLDs were not met in 2 out of 8 1-131 analyses; 1 out of 9 Ca 134 analyses; 1 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 vegetat ion was not met in 1-out of 11 analyses. (See discussion of Program Exceptions in Preoperational Radiological Environmental Monitoring Report for 1985.)
