RIVER BEND STATION RADIOLOGICAL ENVIRONMENTAL OPERATINO rep 0RT POR 1990 Ahrtirsi i

During 1990, a land use census and radiolosleal environmental monitoring were conducted in the vicinity-of River Bend Station (RDS). As part of the monitoring program, the RBS Environmental Setvices Group participated in an interlaboratory comparison. program with 97.4 percent of analytleal results within control limits. The land use census revealed 4 salient chances in receptor: locations since 1989, and the census was expanded to add meat animal receptor locations wlthin the 8 km range. Seventeen monitoring exceptions occurred out of a total effort of 1754 samples collected and 2339 subsequent analyses performed. Fourteen c of these exceptions -involved Technical Specification requirements, although none had significant impact on program quality. . Although well below the required detection limits, slightly elevated (relative to baseline data) levels of Cesium-137 were sporadically measured in Eboth Indicator and cont rol , media; these concentrations were presumably attributable to the'1986 incident at Chernobyl, Russia. The orily measurable increases. In radionuclide activity or levels of radiation attributable to plant operation, in the vicinity of RBS during 1990, appear 4

-to.have been expected low levels. In the 11guld discharge line and traces of airborne I-131 due to small amounts of failed fuel -in the boiler-reactor, i The levels of activity measured in airbornr. media and in the 11guld discharan were below the required LLDs .and. hence substantially belon Technical Specification reporting levels. Thus the 1990 Radiological Environmental Monitoring Program substantiated the adequacy of source control and effluent ,

p monitoring at River Bend Station.

1.0: IFlBQlEC11gh This Annual Radiological Environmental Operating Report for the period of  :

January 1 through December 31, 1990, la 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 MVe General Electric boiling water reactor located in West Feliciana_ parish, Louislana, 4.1 km southeast of St. Francisville 3

-(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_ Hississippi 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 downstr eam of the intake structure (Fig. 2). Gaseous radioactive ef fluents are released through the main plant exhaust - duct, t he 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, verlous crops).

Wetlands, streams / takes, 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 f acilities in the immediate vicinity of RBS are Lambert Redi-Mix Company (1.8-km north-northeast); James River Corporation paper -Hill (5 'i km south)l Big Ca.lun No. 2 power Station (5 km southwest); and the Coips of Engl-neers concrete casting yard (5 km west).

The area within an 80-km radius of RBS'contains all or portions of 19 Loul- _;

sinna parishes .and . five Mississippi counties. This area has generally the same

. makeup as that of the immediate vicinity of RBS, although wetlands, agricultural

. lands, and urban / improved lands are relatively more extensive (at the expense of

.foiested lands) in the southwestern and southeaster n quadrants. _ Baton Rouge, -

centered at, about._38 km_ southeast, is the _only large city _ in the general vicinity of RBS.

During 1990, radiol _ogical environmental monitoring in the v.icinity of RBS was Lperformed 'by' the Gulf _ States litilities Companv-(OSlf) Environmental Services Group

_with support from the Plant- Staf f ~ - Radf ulogical programs Section in maintain-Ing/ calibrating air samplers and in reading / annealing thermoluminescence dosimeters. -

RIVER BEND STATION RADIOLQQ1.Q&g,fNVIRONMENTAL OPERATING REPORT EQR__1190 2.0 RADIOLQQlCAL ENVIRONMENTAL MONITORING PROGRAM (RbfP) 2.1 PurD2se/ Bases i

The Radiological Environmental Monitoring Program (RDIP) was established to e provide representative measurements of radiation and- of radioactive materials, resulting from RBS operation, in those exposure pathways and for those radionuelIdes that lead to the highest potential- exposures of members of the public. The RDiP implements- Section IV.B.2 of Appendix I of 10CFR50 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 applies 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 100FR50, Appendix 1, the program i 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 Elemeats of the RDiP 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. demographic information, are:

Shoreline Sediment Sampics 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, campling 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 RDIP.

The program that evolved during the preoperational 'oaseline) monitoring l phase incorporates all of the elements in the RBS 'rechnical Specifications (3/4.12.1, 3/4.12.2, 3/4.12.3) plus special study criteria, and is illustrated in Table'i and Figures 1 and 2.

2.3 LLnnd tise Qgpsus'for 1990 The 'arinual land use census .was conducted during the 1990 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 f rom those identified in the Radiological Environmental' Operating Report for 1989.  !

The 1990 ' census identifled residences within 8 km - of the RBS renEtor -

containment.-In all _ sectors except L (SW) and M (WSW). The nearest resident in sector M (WSW) was . beyond 8 km In 1990 versus.-4.3 km' in 1989, and the nearest resident ~1n sector P (WNW).was at 3.7 km in 1990 versus 4.1 kai in 1989.~ In sector-E (E), the garden identif f ed in 1989 was discontinued, and in sector 11 (SSE) a new -

garden was established for 1990 : The gardens identified in sectors P (WNW) and Q-

- (NW) are- the onsite gardens established in the sectors with the highest catculated annual average ground : level -D/Q. These gardens are REMP. indicator' locationsfor

- broadleaf vegetation (Table 1,. Fig. 2).

No dairy ~ animals were found w'ithin 8 km of RBS during the 1990_ census.

' llistorically, there had never been enough dairy sites to accommodate the minimum

~ RBS Technical- Specification requirements for analysis of milk (3 locations.within -

l5.km), so monitoring of broadleaf vegetation has.been performed from.the outset.

OSLI_ began a survey of meat animals within the 8 km radius of RDS during the-1990 census.. This _ initial survey identified beef herds in-all sectors except.L

-(SW).

EDIIS_t (1) For purposes of data summary, comparisons, and discussion, the sampling locations designated as "Special Interest" are treated as indicato stations if they are within 16 km of RBS and control stations if they are beyond 16 km.

(2) Sample / measurement location not required by RBS Technical Specifications--(not identified in ODCM).

(3) -Sampling and/or analysis frequency greater than required by RBS Technical Specifications and ODCM.

L(4) 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.

(5) Gross beta analysis not required by RBS Technical Specifications and ODCH.

(6) Drinking water sampling / analyses not required by RBS Technical Specifications aad ODCM. (No drinkina water pathway exists

'due to extreme distance to nearest intake). The upstream surface water sampling location (SW) is used as a " control" .

for drinking water analyses comparisons.

(7) Preferred species are river shrimp (tlEGlatEhlm Alt 19nc), blue

' catfish (1s13h}gs h1LCA11ts), and f reshuter drum ( Aplodinginti gLunnieng); if. these are unavailable, other edible species may-be substituted.-

(8) No irrigation pathway exists due to t.he extreme distance of nearest domestic water intake (see Note 6);. leafy vegetables are- sampled and analyzed because -of limited availability -of milk samples.

=for the gross beta in water for 9/21/90 and for potassium in milk for 4/27/90 are discussed below. The USEPA discontinued the cross-check media for " food" in 1989, and _although milk' sampling and analysis is not 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 (1.e., vegetation and fish) performed by RBS.

and-2339: subsequent analyses-performed. These exceptions and the reasons for the-

-omissions / alterations are delineated in Table 4 in accordance with- Technical Specification reguirements. . Corrective _ actions and impacts on program quality' are

= discussed below, t

Brief storm-related pover. outages impacted one' indic ator air sampler -( AA1) ic January, five indicator end special 11nterest air samplers ( AA1, AB1, AR1, ANS, and AP1) -in June. and one control air sampler (ALC) in >ugust. From 3 percent to

20 percent of each of_ the expected sample volumes was lost due to the power outages.

. A fractured (cause unknown) electrical service pole which suppot ts the weathet head

.and breaker box for the AKS air sampler necessitated disconnection of power, further

1mpacting L AKS _-during November and December. The time taken to replace the electricalt serviceL to AKS,--a sampling location not required by RBS Technical

~ Specifications, -resulted in the loss 'of approximatriy 83 percent - of the expected sample volume for AKS over a 5-week period _. Thes* losses are not deemed to have

, shad a aignificant impact on program quality, espe ially since the plant was shut

' down for. a refueling outage f rom October to December,1990.

Limited variety in the crops due -to a hard freeze during the winter months i

, atethe state. penitentiary (GQC) and both site gardens resulted in failure.to obtain 3 out~ of 36 required control samples and 3 out of 72 required indicator samples 'of l broadleaf vegetation during = 1990. - This did not significantly impact program

?

Equality _One.of the samples obtained from the control leestion (GQC) in June did not satisfy-the LLD requirements due to its low mass.

One USEPA cross-check' analysis for gross beta in water, dated 9/21/90, was

~

M outside the control Timits for accuracy. The sample activity reported by RBS-had been_ calculated using an .-Incorrect factor' for sait density attenuation of beta counting efficiency. When the activity-of the r,ross beta sample was recalculated i

with the. correct salt density factor, the result wau'well within the ilmits for accuracy. One'USEPA cross-check analysis for total potassium was outside the.

control limits- for accuracy. The mass for potassium reported by RBS had been converted from K-40 activity using the incorrect conversion factor (1.19 -instead of 1.133).

R AD I 01,00 I C ALJM BQF}1{ NTAL 0 P ER ATIEUlI2QRLEQlljl90 Gross beta activities in the discharge line and surf ace water samples averaged slightly higher in 1989 and 1990 than in previous years, yet the levels remained well below reporting levels established in the RBS Technical Specifications. These activities seemingly reflect (at least in par t) a slight general increase in levels of beta-emitting materials in the Mississippi River. As observed in previous years, the annual average gross beta activity for the control location (SWU) was higher than that for the indicator location (SWD).

Tritium activities in the discharge line increased on average, reflecting the releases already noted in the 1990 Semiannual Radioactive Effluent Release Reports (see also Table 6). In the RBS boiler-t eactor, ttitium is produced by

- ternary fission of the reactor fuel ( U), although only a small f raction of that tritium would dif fuse through the fuel's cladding. Tritlum is also produced by neutron reactions with certain isotopes of boron, deutet lum and lit hium when present k in the boiler (e.g. as control rod material - boron). The observed tritium increase in the liquid discharge is attributable to the small amounts of failed fuel (i.e.

defects in a very small percentage of the f uel cladding - also responsible for the airborne radiciodine), allowing that tritium produced by ternary fission to migrate

-into the boiler water. The tritium activity observed during 1990 increased beginning in May and continued through November, tapering off with the removal of the failed fuci (see Appendix A, page A-12). Smaller increases of tritium in the liquid discharge would result f rom more ef ficient radioactive wastewater treatment and reuse (e ?, , as boiler makeup). The particulates (metals and salts) are removed in this treatment leaving the tritium behind as water (e.g. , [3H-0 1H]). When this water is reused as boiler makeup, tritium builds up in the water.

It should be noted that Discharge Line monitoring results are based on compos-iten of hourly aliquots of equal volume, rather than on flow-veighted hourly grabs.

While it may be argued that the long-term averages are fairly representative, it can be seen that the sampling requirement would be truly representative only if RBS liquid discharges were continuous and at a constant rate, which is not the case (see also the discussion of liquid ef fluents under Section 3.3 below). RBS changed to flow-weighted composite sampling of the discharge line in 1991 to accomodate NPDES permit requirements for biomonitoring. This change should have a beneficial impact on the comparisons made for predicted releases versus REMP measurements in Table 6.

In the ingestion exposure pathway, no gamma emitting nuclides were measured above LLDs during 1990, and there appear to have been no increases in radionuclide concentrations attributable to RBS operation in food / forage media over basel ine levels ( Appendix B). Slight increases in Cs-137 levels in some fish and broadleaf vegetation samples, pr esumably related to residues of the Chernobyl accident f all-out, were discussed in Section 3.1.4 (above). Naturally-occurring K-40 was measured at an average of 3503 pCi/kg in indicator vegetation and at an average of 4374 pCi/kg in control vegetation in 1990, roughly the same levels encountered prior to 21

l RIVER BEND STATION RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT POR 1990 APPENDIX A Lis t inntn[ 1990 RDIP Rffs3 din The following tables list individual analytical results and direct measurements of radiation (TLD exposures) recorded by the Radiological Environmental Monitoring Program (REMP) during 1990. Activities measured for certain common and readily distinguished, naturally occurring nuclides are included to provide perspective. It should be noted that other gamma emittins, naturally occurring nuclides (e.g., primordial series) were often detected but are not listed because of the complexities and uncertainties of specific identifications.

1. Lower Limit of Detection (LLD) au defined in RBS Technical bpecificationn (NUBEG-ll72).
2. Mean and range based on detectable measurements orly. Fraction of detectable measurementa at speci-

-fled locations in indicated in parentheses. (f)

3. For each of the TLD locations in 1985, a value equal to 1/3 of its 4th Quarter gasuna done la used to almulate a " quarterly" meenuren?nt for October, 1985
4. Beginning in January, 19'15, groundwater was sampled f rom one upgradient (VU = control) and one down-(' gradient (FD - irw11cator) well; previously groundwater was sampled from conutruction dewatering I

wella.

5. The upstream surface water sampling location (swU) la used an a " control" for drinking water compara isons.
6. The values for K-40 were derived from the (then) inciptent fre outie analytical program 7 The values listed for the control location for milk w-re derived from the (then) incipient in-houne analytical program. Training of personnel in calibrition and analytical.siethods delayed sample pre-paration and counting. As a result, the required LLDs were not met in 2 out of 6 1-131 analynes; I out of 9 Ca-134 analyben; I out of 9 Cs-137 analysen; 2 out of 9 ba-140 analyses; and 4 out of 9 La-140 analyses. Similarly, the required L1D for 1 131 in broadleaf vegetation wun not met in ! out of 11 unalyses. (See discussion of Program Exreptions in Preoperational Radiological Environmental Monitoring Report for 1935.)
6. The LLD for one downstream fish sample (catfluh, analyzed in-house) was 265 pCi/kg (wet). The LLD for one upst ream fish sample (largemouth bass, analyzed in-housei van 263 pC1/kg t vet ).
