SUMMARY
The Annual Radiological Environmental Operating Report (AREOR) presents data obtained through analyses of environmental samples collected for the Grand Gulf Nuclear Station (GGNS) Environmental Surveillance Program (ESP) for the period January 1, 1990 through December 31, 1990.
An assessment of plant operation by ESP personnel using AREOR data concluded that no significant relationship exists between GGNS operation and effect on the environs surrounding the Plant. As in previous years, radiation Invels in the environment were undetcetable 11. many cases and at or near background levels in significant pathways associated with GGNS. Therefore, ESP personnel concluded that GGNS operation has had no harmful effects nor resulted in any irreversible damage to the environment.

INTRODUCTION 1.1 SCOPE r
The Annual Radiologica1' Environmental _ Operating Report (AREOR) t
~
presents data obtained through analyses of environmental samples collected for the Grand Gulf Nuclear Station (GGNS) Environmental l
.l Surveillance Program (ESP) for the period January 1, 1990'through December 31, 1990. The AREOR . fulfills the requirements of:GGNS Technical 1 i
Specifications 6.9.1.6 and 6.9.1.7. 3
,s 1.2 PURPOSE AND-DESIGN CRITERIA 0F THE ENVIRONMENTAL. l SMRVEILLANCE PROGRAM (ESP) d The Parnote of the ESP ist-o --
To measure radiation levels and.their_ variations in environmental media in the area surrounding the plant
~
o To determine average levels;of radiation and' radioactive material'in various environmental media ;
o To evaluate: environmental sampling procedures, equipment 1and techniques o To detect effects, if-any, of1GGNSLoperation ~on: the
- environmental radiation levels and concentrations. - j The desion criteria for the ESP are:
o To-analyze important pathways for anticipated types and.
quantities of radionuclides released into1the environment
~
o - To consider:the-possibility <of a buildup offlong-lived
- radionuclides in Lthe environment and identify physical _ and.
' biological accumulations that.may contribute?to human-exposures.
oL To consider;the; potential radiation: exposureJto~ plant and.
animal life in the environment surrounding'GGNS?
-o- To correlate' levels of radiation _ and radioact'ivity; in; thei environment with1 radioactive: releases from stationLoperation.

1.3 DOSE PATHWAYS ASSOCIATED WITH GGNS The most significant environmental dose pathways from a nuclear power station are direct dose from ganeous offluent and thyroid dose due to the Ingestion of allk. GGNS operations are expected to have little, if any, impact by those pathways due to the very low levels of radiation released, the remota location of the station and the absence of milking animals within five miles of GGNS. Also, since the first use of Mississippi River water as drinking water is more than 200 miles downstream of GGNS, the dose from the drinking water pathway is expected to be minimal.
1.4 EHEVIOUS DATA COMPARISON A comparison by ESP personnel of 1990 ESP results to preoperational studios, operational controls and previous AREORs shows no significant changes. As in previous years, ESP results remained at or near
, background levels. Such results confirm that GGNS offluent controls and 1
equipment are performing satisfactorily. i l

2.1.1 JNTERPRETATIONS AND TRENDS OF RESULTS Air particulate and Iodine-131 results for 1990 were similar to those obtained in previous years of the operational and preoperational ESP. Results from 1990 indicate the airborne exposure pathway has not been affected by the operation of GGNS and that airborne concentrations continue to be at or near background levels.
During 1990, a small concentration of Iodine-131 was detected in an air sample that was collected from Newe11 ton, Louisiana as shown in Table 4-2. Although the source was never determined, an investigation by ESP and plant personnel showed no relationship to plant activity and the incident did not recur.
Air particulate indicator and control locations produced similar values in 1990. This emphasizes the fact that air particulate levels remained at or near background and have been uninfluenced by the operation of GGNS. This point is illustrated in Figures 2-1 and 2-2. These figures show that the control location and indicator locetions had similar average values during 1990 (Figure 2-1) and for the past four years (Figure 2-2).-
Yearly average gross beta-emitting radionuclide activity from 1979 through 1990 in Figure 2-3 further emphasizes that GGNS has had no influence on ambient radiation levels. This figure shows a twelve year trend for each indicator location compared to the control location. Control and indicator values were equivalent over the twelve year period which includes operational and preoperational data.
AR808261/JRSFLR 2 i
Environmental Surveillance Program personnel made an independent verification of the accuracy of GGNS results through the use of Mississippi State Department of Health and GGNS collocated air sampling stations. Figure 2-4 indicates that consistent, valid data is being collected based on the-similarity of results.
2.1.2 DEVIATIONS FROM THE ESP Seven air samples required by GGNS Technical Specifications were either missed or deviated from the continuous sampler operation in 1990. _ Listed below are those deviations that occurred 71.9 hours1.041667e-4 days <br />0.0025 hours <br />1.488095e-5 weeks <br />3.4245e-6 months <br /> run time for AS-07 ending on January 2, 1990 due to blown fuse 78.6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> run time for AS-07 ending on January 30, 1990:due to vacuum failure 42.4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> run time for AS-03 ending on February 13, 1990 due to blown fuse missed sample for AS-06 ending on May 1, 1990 due to mechanical failure 135.1 hours1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> run time for AS-07 ending on August 28, 1990 due to blown fuse 53.1 hours1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> run time for AS-07 ending on September 11, 1990 due to blown fuse

Footnote (a) to GGNS Technical Specifications Table 3.12.1-1 permits deviations from the required-sampling schedule if' specimens are unobtainable due to malfunction of automatic sampling equipment. No other deviations occurred..
2.1.3 PROGRAM DESCRIPTION The GCNS Environmental Surveillance Program used eleven continuous. air samplers to provide gross beta-emitting l-radionuclides, gamma-emitting radionuclides and radiolodine activity measurements by the airborne' exposure pathway. These-I:
AR808261/JRSFLR 3
air samplers were plisced at distances from 0 to 18 miles,_as shown in Figures 2-5 t.hrough 2-7 and Table 2-1. Five of the air samplers were used to moet the requirements of GGNS Technical Specification 4.12.1. Placement _of the five required air- ]
1 namplers is as follows: )
o Three near the SITE BOUhDARY in areas of the highest calculated annual average broundlovel D/Q values i o One in a community that has the highest calculated annual average groundlevel D/Q value-(Port Gibson) o One in a control location (Vicksburg, MS).
The remaining six air samplers woro located-in areas which provide additional data for the ESP.
The air samplers were placed one motor above the ground in-weathorproof houses. A-2-inch glass fiber filter was installed in the intake line of the vacuum pump with a 2_x 1-inch charcoal cartridge located directly downstream. Flows were adjusted-to 1.25 cubic feet por minute. Filters and cartridges: ware changed weekly and analyzed for gross beta-emitting radionuclides and radiolodine activity, respectively. In addition, the-111ters were composited quarterly and analyzed for gamma-omitting radionuclidos.

P 2.2 TilERMOLUMINESCENT DOS 1 METRY (TLD) i I
NOTE #1: Analytical results are presented in Attachment II and summarized in Section 4.0.-
NOTE #2: 'TLD Locations are shown in Figures 2-5 through 2-7 of Section 2.1.-
i l-AR808261/JRSFLR 2-17 I
2.2.1 INTERPRETATIONS AND TRENDS OF RESULTS Gamma radiation dose in 1990 was measured with thermoluminescent dosimeters (TLDs) on a quarterly schedule.
There was no significant difference in 1985 through 1990 average dose rates as illustrated in Table 2-2.
Direct radiation dose to the public from 1983 through 1990 '
is presented in Table 2-3. As indicated in Table 2-3 the overall operation of GONS has had minimal impact on direct radiation dose to the public.
Indicator and control locations for 1990 produced similar values. This indicates that the ambient radiation icvols remained at or near background and have been uninfluenced by the operation of GGNS. This conclusion is represented in Figures 2-8 and 2-9 showing 1979 through 1990 annual average of quarterly average TLD results and 1989 through 1990 quarterly average TLD results.-respectively. These figures also indicate that ambient radiation levels have remained at or near background levels.
Environmental Surveillance Program personnel performed an independent verification of the accuracy of GGNS TLD results through the use of NRC and GGNS collocated TLDs. Figuro 2-10 presents NRC and GGNS collocated TLD results for the. eleven most recent quarters available. This figure indicates that consistent, valid data is being collected based on the similarity of TLD results.
AR808261/JRSFLR -l2-18; ,
l q
l 2.2.2 DEVIATIONS FROM THE ESP Six TLDs required by GGNS Technical Specifications were lost in the fleid durlug 1990. Vandalism and flooding of the Mississippi River caused these losses. TLD losses of this type are characteristic of other TLD programs. The 1990 recovery rate for TLDs required by GGNS Technical Specifications was 96% (154 of 160) and is comparable with other TLD programs. l 2.2.3 PROGRAM DESCRIPTION l
Environmental Surveillance Program personnel measured i ambient radiation in the environment surrounding GGNS with 94 TLD cards (calcium sulfate: dysprosium phsrphor dosimeters) to provide a quantitative measurement of the area radiation levels.
Environmental Surveillance Program personnel placed these environmental TLDs at distances from 0 to 18 miles. as shown in Table 2-4. .
Each dosimeter was sealed in a plastic protective holder and normally suspended one metet above the ground. The dosimeters were collected quarterly.
The criteria used in establishing TLD locations area o GGNS Technical Specification 4.12.1 requires 40 TLDs to be positioned as outlined below:
An inner ring of 16 stations in the general area of the site boundary with one TLD in each raeteorolog; cal sector An outer ring of 16 stations approximately in the ,
3.to 5-mile range with one TLD in each '
meteorological sector Eight TLDs located in special interest areas such as population centers and residences or utilized as controls. ;
AR808261/JRSFLR 19_
o Twenty-four permanent TLD stations at the protected area boundary. ,
o The remaining 30 TLDs in areas'away from the GGNS site.
These TI,Ds gather'supplomontal and supporting data for determining direct radiation doso.
In nummary, the TLD locations are as follows:
No. of Lonal.long o Technical Specifications requirement

- Outer Ring 16 Population Centors & Controls 8-o Protected Area Doundary 24 o Supplemental Dr.ta _39_

2.3.1 INTERPRETATIONS AND TRENDS OF RESULTS Milk samples within five miles of the GGNS site wete unavailable in 1990 due to the absence of milking animals. Hilk samples from the Alcorn State University control location were collected semiannually and analyzed for Iodine-131 and :
gamma-emitting radionuclides. As in previous years, no radioactivity attributable to GGNS was detected in milk samples.
The ingestion pathway shown in Technical Specification Table 3.12.1-1 specifies the frequency and location for obtaining milk samples. If milk sampling is not performed, the ingestion section provides for.the use of a food product pathway as an alte rnative. This alternative was utilized in 1990 and is described in Section 2.5 of this report. 3 2.3.2 DEVIATIONS FROM THE ESP As noted above, milk samples were unavailable within five ;
miles (8 km) of GGNS in 1990. Therefore, ESP personnel reduced -
sampling frequency at the Alcorn. State University control t
location to semiannually until such time that milk samples become available within five miles (8 km) of GGNS.
Because of milk unavailability, ESP personnel collected vegetation samples to monitor the ingestion pathway, as specified ~l in Technical Specification 3.12.1-1. 4 2.3.3 PROGRAM DESCRIPTION GGNS Technical Specifications required sample collection l from milking animals in three locations within a five km distance
! having the highest dose potential. If there were none, then one AR808261/JRSFLR 38

2.4.1 INTERPRETAT10NS AND TRENDS OF RESULTS Environmental Surveillance Program personnel sampled cistern-water, surface water and groundwater as required during 1990.
Analytical results were similar to those reported in previous years.
Cistern Water Cistern water samples were collected from two locations and analyzed for gross beta-omitting radionuclides, Iodine-131, tritiun and gamma-omitting radionuclides. As in previouc years, gamma-emitting radiunuclides, Iodine-131, tritium and gross beta-omitting radionuclides continue to be at or near background levels.
Surface Water Surface water samplee included the upstream and downstream Mississippi River and the Discharge _ Basin. These samples were collected monthly and analyzed for gamma-emitting radionuclidos.
Samma-emitting radionuclido concentrations continued ~to be at or near background levels in upstream, downstream and Discharge Basin samples.
In addition, composites from each. location were analyzed quarterly for tritium. Tritium invols for Discharge Basin surface water ranged from 531-1930 pC1/1 with a mean of 1021 pC1/1. This activity is attributed to plant operating' levels and radwaste discharges in 1990. Tritium continues to be at or near
~
n background levels at the upstream and downstream Mississippi l
l River locations. Tritium results from 1985_through 1990 for the 1
Discharge Basin are provided in Figure 2-11.

2.5.1 INTERPRETATIONS AND TRENDS OF RESULTS i
Analytical results for-vegetation in 1990 and previous years have shown no data which was attributable to the operation of GGNS. Radionuclide levels for vegetation continue to remain at background levels.
2.5.2 DEVIATIONS FROM THE ESP Vegetation samples required by GGNS Technical Specifications were collected and analyzed during 1990 without exception.
2.5.3 PROGRAM DESCRIPTION Since milk samples were_ unavailable within five miles of GGNS, broadioaf vegetation samples were collected for the measurement of radioactivity-by the ingestion exposure pathway.
Samples of three different kinds of broadleaf vegetation grown nearest each of two different offsite locations with the highest anticipated annual average groundlovel D/Q were requirnd.
Environmental Surveillance Program personnel met vegetation sampling requirements by maintaining two gardens inside the- SITE B0"NDARY, Sectors J and R. _These sampling locations (Table 2-8) provided a more-conservative assessment of doses due to the higher deposition rates (D/Qs)_than would be measured atioffsite sampling locations.
The GGNS Technical Specifications also required control-samples of each of the similar types of onsite vegetation 15-30 i
km from the site. To fulfill this requirement, a control.
vegetation sample location has'boen established in Sector K at Alcorn State University-(Table 2-8).
AR808261/JRSFLR 49 i- .j
The preferred source of broadleaf.vogotation was green-leafy vegetables suitable for human consumption. If such vegetables were not available, samples of any vegetation with relatively broad leaves on which airborno radioactive particulato material.
might be deposited were sampled. The raw samples woro.then analyzed for gamma-emitting radionuclidos and Iodine-131.

2.7.1 INTERPRETATIONS AND TRENDS OF'RESULTS Fish samples were collected semiannually and analyzed for gamma-emitting radionuclidos. Analytical results for fish in ,
1990 and previous years have shown no data which was attributable to the operation of GGNS.
2.7.2 DEVIATIONS FROM THE ESP Fish samples required by GGNS Technical Specifications were collected and analyzed during 1990 without exception.
2.7.3 PROGRAM DESCRIPTION Fish woro collected semiannually in the Mississippi River at the following locations (Table 2-11):
o Minimum of 1000 yards upstream from the GGNS barge slip (control location) o Minimum of 2000 but less than 6000 yards downstream from the GGNS barge slip (indicator location)
Fish can be collected by not, trotlino, electroshock or purchase from commercial fishermon. If samples -woro purchased from a l'
! commercial fisherman, ESP personnel accompanied the fishorman to l
l ensure samples were collected from the required-locations, l
A sufficient amount was collected from each location to
! provid s a minimum of 1000 grams (wet weight) of eviscerated fish samplo. The samples were analyzed for gamma-omitting radionu.lides.-

2.9.1 INTERPRETATIONS AND TRENDS-OF RESULTS l Although some minor changes-occurred from 1989 to 1990, as shown in Table 2-12, there was no need to modify the ESP. Also, there was no. location identiflod which yielded a calculated dose or doso commitment greater than those currently being calculated.
The re;olts of the 1990 Land Use Consus indicated the land-uses in the zero to 5-mile area surrounding GONS have romained
-basically the same as those reported in the 1988 and 1989 Annual Land Use Consus. The 1990 Land Use Consus data shoots are presented in Tablo 2-13.
2.9.2 DEVIATIONS FROM THE ESP The Annual Land Use Consus required by GGNS Technical Specifications was conducted during-1990 without exception.
2.9.3 PROGRAM DESCRIPTION i
l As required by-GGNS Technical Specification 3.12.2, ESP personnel conducted an Annual Land Use Consus. The-purpose of
( the census was to identify changes in the uses of land in the l
unrestricted areas surrounding GONS which would require modifications to the ESP' or the Offsite Dose Calculation Manual (ODCH). The most important critoria during the census woro to-datormine the location, in nach of the 16 meteorological sectors, of the nearest:

3.1 SAMPLE IIANDLING AND TREATMENT f once a representative sample is received by the analytical laboratory, the laboratory staff is responsible for properly treating and stor!.ng the samplo. Environmental samples frequently require treatment prior to analysis. Treatment of the sample after it is roccived depends on the sample and the analyses to be performed on it.
3.1.1 Water Samoles Generally, one-gallon water samples were acidified with five ml of concentrated hcl acid when collected. Samples for tritium ,
analysos should not be stored in polyethylene bottles for more than 3 or 4 months because water can evaporate through the polyethylene.
3.1.2 Air P11ters Air filters were handled with care when heavy dust loadings were observed becauso particulato matter is easily removed from the filter. Air filters were normally roccived by the laboratory in plastic containers; some extremo1y low-level analyses required analysis of the container as well as the sample.
3.1.3 Kilk Hilk samples were usually refrigerated until analyses could be performed. If analysos were delayed for more than a few days, a preservative (formaldehyde) was added to inhibit bactorial growth and retard spoilage. Hilk samples analyzed for lodino-131 had 100 m1 formaldehyde added to avoid binding of the iodino that may occur with smaller levels of formaldehyde.

3.1.4 Soil and Bottom Sediment Soil and sediment sampics were dried, pulverized and sieved before analysis. To ensure a homogeneous sample, thorough mixing was required.
3.1.5 Other Sampics Perishable sampics were preserved by refrigeration or freezing. Vegetation and other samples may need to be dried.. ,
pulverized or ashed before or after analysis for long-term storage.

The program also compared the energy of each peak with a library of peaks for radionuclide identification and then performed the radioactivity calculation using the appropriate fractional gamma ray abundance, half life, detector officiency and not counts in the peak region.
3.6.2 Verotation. Food and Garden Crop.L and Fish A maxt:num quantity of undried vegetation,- food or garden crop sample was loaded into a tared 3.5-liter Marinelli.boaker and wofghed. The sample was then counted for a minimum of 200 minutes, or until the required LLDs were achieved, in a shielded Gohl detector as described in Section 3.6,1.
As much as possible (up to the total sample) of the edible portion of a. fish was loaded into a tared Marinelli banker and weighed. The sample was then diluted with defonized water to r wofgh 3.5 kg and counted for a minimum of 240 minutos in a shielded Gobi detector as describod' in Section 3.6.1.
3.6.3 So11s and Sediments
(
Soils and sediments were dried at a low temperaturo (less than 100'C), loaded into a tarod 1.0-11ter Marinelli beaker and weighed. The sample was than counted for 240 minutos.-or until l
the required LLDs were achieved, in a shielded GoLi detector as l
l described in Section 3.6.1.
l 3.6.4 Charcoal Cartrideos Charcoal cartridges were counted in a Marinelli boaker,-with one to four cartridges positioned on the face of a Gobi detector and up to sovon cartridges on its side. Each detector was
'AR808261/JRSFLR 6
calibrated for both top and side positions and a counting efficiency determined. The lodine-131 detection limit was determined for each charcoal cartridge, assuming no positive results for Iodine-131, by utilizing the smallest volume of air recorded for a cartridge within the Marinelli beaker. If Iodine-131 was observed in the screening count of a set of cartridges, each charcoal cartridge was positioned on the face of the detector and then counted separately, s
3.6.5 Air Partfeulatu i i
The 12 to 14 (depending on the calendar quarter) air particulate filtern for a quarterly composite for each field station were stacked one on top of another and counted for at least four hours, or until the required LLDr, were achieved, in a shielded GeLi detector as described in Section 3.6.1.
The calculations of results, two sigma error and the lower limit of detection (LLD) in pC1/ volume or pCi/ mass were performed as indicated in the following: ;
RESULT = (S-B)/[(2.22 T E V F) exp(-1Ats)) 4 TWO SIGMA ERROR = (1.96 JS+B)/[(2.22 T E V F) exp(-XAts))
LLD = (4.66 $ [(2.22 T E V F) exp(-lats))
where: S= Area, in counts, of sample peak and background (region of spectrum of interest)
B= Background area, in counts, uader sample peak, determined by a linear interpolation of the representative backgrounds on either side of the peak 2.22 = dpm/pC1 T= Length of time in minutes the sample was counted E= Detector efficiency for energy of interest and geometry of sample i
i AR808261/JRSFLR 7
V= Sample aliquot size (liters, cubic meters, kilograms, or grams) 1 F= Fractional gamma abundance (specific for each emitted gamma) exp(-kats) = Decay factor from the time of collection to the counting date 3.7 IllERM0 LUMINESCENT DOSIMETERS (TLDs) ,
' l Environmental radiation doses were measured using TLD cards impregnated with calcium sulfatetdysprosium phosphor scaled in plastic protective holders. These TLD cards had four main readout areas utilized in calculating dose rates and four reserve areas as a backup dosimeter.
Prior to installation the cards were spread out in a single layer on a perforated metal tray and annealed for two hours at 250-260'C. After i
cooling, the cards were mounted in a card holder, scaled in a plastic protective holder and shipped for placement in the ficid.
Upon return from the field, the TLD cards were read in a Tolodyne Isotopes Model 8300 TLD Reader. After readout, the cards were annealed again and irradiated with a known dose using a Radium-226 source 1 encapsulated in'an iridium needle and then read again to determine the i card ef ficiency. The not exposure was calculated by the computer after in-transit exposure was subtracted.- The LLD for environmental TLDs is i
1 mrem / quarter. !
3.8 DATA REPORTING CONVENTIONS The mean-of analytical results is as follows:
i = I Xf / n !
Where 1 l 5 = Mean ,
l Xi = -Individual sample results n = Number of sample results

Rounding of calculated values is accomplished by inspection of the digits to the right of the last reported digit with values less than 5 rounded down and values greater than 5 rounded up. When the value equals 5, the reported value is rounded to an even number.
Analytical results which are less than the 2 sigma counting error are reported as less than the 1.LD calculated for that sample. Analytical results greater than the 2 sigma counting error are reported along with the associated 2 sigma counting error as a plus or minus (1) term.
Calendar quarters are considered to be the following time periodat IST QUARTER = JAN - MAR 2ND QUARTER = APR - JUN 3RD QUARTER = JUL - SEP 4Til QUARTER = OCT - DEC 1

4.1 1990 PROGRAM RESULTS
SUMMARY
Results of the esp for 1990 are summarized in Tables 4-1 and 4-2.
Results from sampling locations required by GGNS Technicel Specifications, which are identified in Sections 2.1 through 2.7, were used to develop Table 4-1. Tabic 4-2 includes results from all sampling locations, not just those required by Technical Specifications.
Indicator and control locations for Table 4-1 are as designr.ted by the GGNS Technical Specifications and summarir.ed in Table 4-3. Indicator and control locations for Table 4-2 are listed in Table 4-4. For ,
l determining ranges and means for indicator and control locations, values I reported as less than (<) were not used.

5.1- CROSSCHECK PRQQRAM RESULTS Arkansas Power & Light's (AP&L) Technical Analysis Section analyzed the crosscheck samples for GGNS. The results of GGNS' Crosscheck Program are provided in Attachment I, 1990 Environmental Sampling and Analytical Report. Graphs of AP&L's intercomparison results are provided in Figure 5-1. This figure indicates that AP&L reports consistent, valid data j based on the similarity of EPA and AP&L results.
Telodyne Isotopes Midwest Laboratory provided thermoluminescent q dosimeter (TLD) analytical capabilities. Attachment II contains the most recent results obtained through Telodyne's-participation in the.
International Intercomparison of Environmental Dosimeters. Results were within the acceptable range of deviation.
5.2 DUPLICATE SAMPLES Results for duplicate samples lof water, milk, fish, sediment, sewage and vegetation media submitted by GGNS to AP&L are included in Attachment I. These results are in the appropriate tables and-identified by the suffix (GG) accompanying the laboratory number. Table 5-1 summarizes the results of the ESP duplicate sampling for 1990.
A graph presents results _ for duplicate TLDs from 1987 through 1990 in Figure 5-2; This figure which is based on averaging the three duplicate and permanent TLD location results, shows that consistent, valid data is being reported based on the similarity of.results.-

1 SECTION 6.0 1990 SAMPLING AND ANALYTICAL RESULTS 1
l l
l l
l AR808261/JRSFLR 1
6.1 1990 DATA Attachments I and 11 presents data obtained by Arkansas Power and Light's (AP&L) Technical Analysis Section and Teledyne Isotopes Midwest Laboratory on samples collected from January through December 1990. With the exception of thermoluminescent dosimeters (TLDs), data was provided by AP&L in monthly progress reports. Teledyne Isotopes provided TLD data i
in quarterly reports.
Data' presented in Attachments lt and II is comparable to that encountered in previous years.
6.2 LOWER LIMIT OF DETECTION (LLD)
In many analyses, the LLD achieved by the AP&L Technical Analysis Laboratory was lower than the maximum LLD permitted by GGNS Technical Specification Table 4.12.1-1. Factors such as unavoidable small sample size, background fluctuations, the presence of interfering radionuclides or ather uncontrollable circumstances may cause the Technical Specifications' LLD to be unachievable. However,- in 1990 all Technical Specification LLDs were achieved.
6.3 REPORTING LEVELS Radioactivity attributable to GGNS was found in the discharge basin water, sewage sludge and barge' slip sediment. However, no reporting -
1 1evels for radioactivity concentration in environmental samples, as outlined in Technical Specifications Table 3.12.1-2 when averaged over 1
any calendar quarter, were_ equaled or exceeded due to GGNS effluents.
One radionuclide (Chromium-51), which is not listed in the GGNS Technical--
l 1 Specifications Table 3.12.1-2, was detected during 1990 in the barge slip sediment. However, the quantity detected was not capable of causing a i
! AR808261/JRSFLR 1
dose to a member of the public. exceeding the calendar year limits of -
Technical Specifications- 3.11.1.2, 3.11.2.2 and-3.11.2.3. Therefore, no Radiological Monitoring Program Special Reports were required.
6.4 _ SAMPLING DEVIATIONS Samples required by GGNS Technical Specification 3.12.1 were
.y collected within the scheduled period unless noted otherwise in i
Attachments I and II.
Sample deviations at locations required by GGNS Technical :
Specifications are discussed in Sections 2.1.through 2.7. These sections provide more explanation concerning reasons why samples were missed and describes corrective action-where appropriate.
6.5 RADI0 ACTIVITY NOT ATTRIBUTABLE TO GGNS i
Radioactivity attributable to other sources has been detected twice by the GGNS ESP. In early 1980, the 25th Chinese nuclear test explosion-was detected. In 1986, the radioactive plume release duesto reactor _ core degradation-at the Chernobyl Nuclear Power Plant was detected.
6.6 SAMPLING RELOCATION -
Sampling locations did not change in11990. Therefore, there was no i
need to-identify new locations and report-the circumstances of unavailability in the Semiannual Radioactive Effluent Release Report.
6.7 COMPARISON TO FEDERAL AND STATE PROGRAMS Data from the-GGNS ESP was compared to federal and state monitoring !
programs as the results became available. The federal monitoring .
program used for comparison was the U.S. Nuc1 car' Regulatory Commissica-(NRC) TLD Direct Radiation Monitoring Network. The state programs are conducted by the Mississippi State Department of Health, Division of Radiological Health, and the Louisiana Department of Natural Resources, Nuclear Energy Division.
I AR808261/JRSFLR 2
l l
l The latest available results from the NRC TLD Network have been j comparable to those from the GGNS ESP through September 1990. These
, results cover 33 TLD locations, 16 of which are collocated. On the
{
average, collocated TLDs have produced similar results.
l Prior to September 1990, no change in collocated TLD results has been attributed to GGNS operation.
Radiological monitoring by Mississippi-and Louisiana agencies entails similar sampling requirements as the GGNS ESP. In many cases air samples and TLDs are collocated, while sample media such as vegetation, water, sediment, fish and milk are shared or split. Through 1990, all three programs have obtained results that are within similar ranges. The only common location where radioactivity attributable to GGNS has been detected is the GGNS barge slip. Barge slip sediment results were above background due to GGNS effluents.
1 6.8 UNAVAILABLE RESULTS Analytical contractor results were received in adequate time for inclusion. No missing results were identified during ESP personnel's review of these results.
6.9 HARMFUL EFFECTS OR IRREVERSIBLE DAMAGE No harmful effects or evidence of irreversible damage were detected by ESP monitoring. Therefore, no analysis or planned course of action to s
alleviate problems was necessary.
