SUMMARY
The Annual Radiological Environmental Operating Report ( AREOR) provides Grand 2 Gulf Nuc1 car Station (GGNS) Environmental Surveillance Program (ESP) data obtained through analyses of environmental samples collected foi the period January 1,1991 through December 31, 1991. The AREOR fulfills the requirements of GGNS Technical Specifications 6.9.1.6 and 6.9.1.7. ENVIRONMENTAL SURVEILLANCE PROGRAM GGNS established the Environmental Surveillance Program (ESP) six yearn. before i the station became . operational to provide data on background radiation and radioactivity normally present in the area. ESP personnel monitor radiation aid radioactivity around GGNS within an 18-mile radius. GGNS has continued to monitor the environment for 14 years by sampling air, milk, water, vegetation, sediment and - fish, as well as' measuring radiation directly.
~
ESP personnel co73ect samples from indicator and control locations. Indicator locations are within five miles of the site, and are expected to show any increases or buildup of radioactivity that might occur due to station operation. Control locations are farther away from the station, and are expected to indicate the presence of- only naturally occurring radioactivity. Indicator results are compared with controls and preoperational results. This allows ESP personnel to assess any i impact GGNS operation might have had on the surrounding environment.

In 1991,-ESP personnel collected and analyzed 1700 radiological environmental samples for' radioactivity. GGNS compared radionuclide concentrations measured at indicator locations to concentrations at control locations and those measured in L previous studies, and they concluded that no significant relationship exists between GGNS operation and effect on the environs surrounding the plant. Radiation levels in the environment were undetectable in many cases, and near background levels in l 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 RADIATIQG People are always subjected to natural radistion. This radiation exposure comes from the sun, naturally occurring radioactive materials present in the earth, structures we inhabit, food and water we consume, the air we breathe, and our bodies are, themselves, radioactive. The levels of natural or background radiation vary greatly from location to location. Han-made sources such as-X-rays, radiation for medical purposes, fallout from nucicar explosives testing, and radioactive materials from nuclec wer plants contribute additional radiation. Ilowever, as shown in Figure 1-1, an individual receives the major portion (99%) of dose from natural background and other sources, with nuclear power plants contributing the least. 1.2 DENEFITS OF RADIATION Uranium used in nuclear power plays an important part in meeting today's electricity needs, and will continue to serve as an important source of energy well'into-the future. In addition, other uses of radiation have brought tremendous benefits to our everyday lives during the past 20 or 30 years. Radioisotopes and controlled radiation are used to sterilize medical supplies, , to improve food preservation, in industrial processes, in medical science, and i in the study of environmental pollution, agriculture and hydrology. Medical diagnosis and treatment is the main source of public exposure to man-made radiation but the benefit in. terms of human lives and health is enormous. n RADEVN.RPT/SRREVFLR-1-1 y-w-c=. - - r-,, ,,...._,,m -

1.3 SAFETY OF RADIATION Radiation and the safety of radiation command considerable public attention. Although it is not generally realized, safety regulations for
. radioactive materials are much stricter than for other dangerous substances.
For example, in the case'of coal, it has been ostimated that in Pennsylvania 30,000 miners died in the mines between 1870 and 1950, an average of about one man a day for 80 years. If the nuclear power industry were compared to thin toll, one could see how the safety history would be uniquely encouraging. In addition, radioactive elements gradually lose their radioactivity and toxicity with time. Other non-radioactive materials, such as arsenic, remain toxic forever. It was reported that three years after an accidental dioxin chemical release in Seveso, Italy, in 1976, the dioxin deposited in the region showed no signs of diminish!ng. These examples demonstrate how the safety of radiation tends to be viewed separately from other, and sometimes i greater safety hazards. 1.4 PURPOSE AND DESIGN CRITERIA 0F THE ENVIRONMENTAL SURVEILLANCE PROGRAM (ESP) Grand Gulf Nuclear Station established the Environmental Surveillance Program (ESP) to minimize any associated radiation endangerment to human health or the environment by ensuring the proper function of plant operating controls. . The nurcose of the ESP is: o To evaluate environmental sampling procedures, equipment and techniques ! -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 L o To detect effects, if any, of GGNS operation on the environmental radiation levels and concentrations. l l i \ l 4 4 RADEVN.RPT/SRREVFLR-1-2 l o < l i 4

The desien crj.teria for the ESP are: o To analyze important pathways for anticipated types and quantitles of radionuclides released into the environment o To consider the possibility of ,. buildup of long-lived radionuclides in the environment and identify physical and biological accumulations that .1 may contribute to human exposures
- o. To consider the potential radiation exposure to plant and animal life in the environment surrounding GGNS o To correlate-levels of radiation and radioactivity in the environment with radioactive releases from station operation.
1.5 DOSE PATHWAYS ASSOCIATED WITH GGNS Figure 1-2 shows potential exposure pathways that could-occur as a result of a nuclear power plant. However, the most significant environmental dose 1 pathways from a nuclear power station are direct dose from gescous effluent and thyroid dose due to the ingestion of milk. GGNS operations have little, if any, irpact on these pathways due to the very low levels of radiation released, the remote location of the station and the absence of milking animals within 3 five miles of GGNS. Since first use of Mississippi River as drinking water is more than 200 miles' downstream, GGNS operations have little, if any, impact on this pathway. , 1.6 ' PATHWAYS MONITORED ESP personnel monitor and implement the required sampling program for airborne, waterborne, . ingestion and direct radiation pathways as . required by [ GGNS Technical Specifications. This program is supplemented with additional 2
. sampling in order to provide a comprehensive and well-balanced program.
D Figures 1-3, 1-4 and 1-5 show sample locations where exposure pathways are
~ monitored. ~ Section 2.0 of this report contains sampling location tables and discusses 1991 sampling results.

5-1.7 PREVIOUS DATA COMPARISn3 Environrantal fiury, 41anco Pror' 'm personnel observed no significant changes between 1991 results and those from previous years. Results remained at' levels similar to those of previous years. Such results confirm that GGNS ef fluent controls and equipment are performing socisfactorily. I' I: i l l l 1 l' i , ? I I l

2.1.1 LNIERPRETAT10SS AND TRENDS OF RESULTS I Air particulate and Italine-131 results for 1991 weie skilar to those obtained in previous years of the operational and preoperational ESP. Results from 1991 Indicate the airborne exposure pathway has not been af f ected by the operation of GGNS and that airborne concentrations continue to be at background levels. Gross beta concentrations shown in Figure 2-1 emphasize that GGNS has had no influence on ambient radiation levels. This figure shows _ 1991 monthly average results compared to preoperational results aml 1978 through 1991 yearly average results for indicator locations compared to controls. Values were equivalent over the period. Environmental Surveillance Program personnel also made an independent verification of the '.ccuracy of GGNS rer ults through the use of Mississippi State Department of Ilealth, Louisiana Nuclear Energy Division and GGNS collocated air sampling statient:. Figure 2-2 indicates the ESP collects consistent, valid data based on the similarity of results. 2.1.2 DEVIATIONS EROM THE ESP An air sample was missed at AS-1 PG located in Port Glbson on April 23, 1991 due to the air sampler unit not being restarted. ESP personnel revised air sample collection procedure to allow collection while air sampler unit remains operational. This problem did not recur in 1991, and no other deviations occurred.

2.1.3 PROGRAM DEliCRIPTION The GGNS Environmental Surveillance Program used eleven continuous air samplers to providn gross beta, gamma and radiolodine act.ivity measurements by the airborne exposure pathway. These air samplers ranged in distances from 0 to 18 miles (Figures 1-3 through 1-5 Table 2-1), Five air samplers met the requirements of GGNS Technical Specification 4.12.1 located as follows: o Three near the SITE BOUNDARY in areas of the highest calculated , annual average groundlevel D/Q values o One in a community that has the highest calculated annual ' average groundlevel D/0 value (Port Gibson) o One in a control location (Vicksburg, MS). The remaining six air samplers were in areas which provide addit.fonal i data for the ESP. The air samplers were one meter above the ground in - weatherproof houses, with a 2-inch glass fiber filter in the intake line of the vacuum pump and a 2 x 1-inch chorcoal cat tridge located directly downstream. Air flow was 1.25 cubic feet per minute. ESP personnel changed (11ters and cartridges weekly and had then, analyzed for gross beta radionuclides and radiolodine activity, respectively. Quarterly composites of air filters underwent gamma analysis. l b RADE5/N.RPT/SRREVFLR-2-3

I 2.2.1 INTERPRETAT_LQNS AND TRENDS OF RESULTS Gamma radiation dose in 1991 was similar t,o t.het. obtained in previous years as illustrated in Table 2-2. This indicates that the ambient radiation levels remained at or near Lackground and have been uninfluenced by the operation of GGNS. Figure 2-3, which further represent.s this conclusion, shows 1991 , quarterly average results compared to 1979-1984 preoperational data and.1979 - 1991 annual quarterly average results for indicator locations compared to the Vicksburg control. This figure indicates that ambient radiation levols have remained at or near background levels. As in previous yearc, Environmental Surveillance Program personnel performed an independent verification of the accuracy of
- GGNS TLD results throu
- the use of NkC and GGNS collocated TLDs.
Figure 2-4 presents NRC and GGNS collocated TLD results and indicates the ESP collects consistent, valid data based on the similarity of TLD results. 2.2.2 DEyIATIO:s FFJ)LIliE_EE Due to vandalism or flooding from the Mississippi River during 1991, EEP personnel were unable to find eleven TLDs required by GGNS Technical Specifications. In addition, ESP personnel were unable to place two TLDs in the field due to river-flooding during the first quarter of 1991. TLD losses of this type are characteristic of other TLD programs. The 1991 recovery rate for TLDs requirod by GGNS Technical Specifications was 93% (149 of 160) and is omparable with other TLD programs. RADEVN.RPT/SRREVFLR-2-8

Environmental i Surveillance Program personnel placed thete environmental TLDs at distances from 0 to 18 miles (rigures 1-3 through 1-5, Tabic 2-3). i ESP personnel collected dosimeters quarterly. l The criteria used in establishing TLD locations are: 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 meteorological sector
- An outer ring of 16 stations approximately in the 3-to 5-mile range with one T1.D in each meteorological sector Eight TLDs located in special interest areas such as population centors and residences or utilized as ,
controls. o Twenty-four permanent TLD stations at the protected area boundary, o The remaining 30 TLDs in areas away from the GGNS site. These TLLs gather supplemental and supporting data for determining direct radiation dose.

2.3.1 INTERPRETATIONS'AND TRENDS 0" RESULTS Milk samples within five miles of the GGNS site were unavailable in 1991 due to the absence of milking animals. Therefore, milk 3 samples from the Alcorn State University control location were collected and analyzed for Iodine-131 and gamma radionuclides. As in previous years, no radioactivit, ttributable to GGNS was detected in milk sampics. The ingestion pathway shown in Technical Specification Table 3.12.1-1 specifies the frequency and iocation for obtaining milk samples. If milk sampling is not performed Table 3.12.1-1 provides for the use of a food product pathway as an alternative. This alternative was utilized in 1991 and is described in Section 2.5 of this report. 2.3.2 DEVIATIONS FROM THE ESE As noted above, milk samples were unavailabic wJthin five miles . (8 km) of GGNS in 1991. Therefore, ESP personnel reduced sampling . frequency at the Alcorn State University control location to semiannually until such time that milk samples become available within five miles (8 km) of GGNS. i Because of milk _ unavailability, ESP personnel collected l l- vegetation samples to monitor the ingestion pathway, as specified in Technical Specification 3.12.1-1. t 2.3.3 PROGRAM DECCRIPTION GGNS Technical Specifications required sample co11cetion from milking animals in three locations within a five km distance having the highest dose potential.

L' sample was required from milking animals in each of three areas, between five to eight km', where doses were calculated to be greater than one mrem per year. Also requited was one control sample at a distance of 15-30 km. A control milk sample was collected semiannually from the Alcorn State University Dairy (Figure 1-4, Table 2-4) to establish l bcckground data. h iver milk animals were unet.nilable in 1991 l -- within eight km (five miles) of GGNS.

Surface litter samples from the Mississippi hiver were collected monthly at points upstream (control location) and downstream (indicator location) of the plant discharge (Figure 1-3, Table 2-5).
. Surface water was analyzed monthly for gamma radionuclides and a ccmpusite was analyzed quarterly for tritium.
An additional surface water sample was taken from the GGNS

2.5.1 INTERPRETATIONS AND TRENDS OF RESULTS Vegetation samples were collected and analyzed for gamma radionuclides and Iodine-131. As in previous years, concentrations 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 1991 without exception. 2-5.3.
. .PROGRAd_ DESCRIPTION Since milk samples were unavailable within five miles of GGNS, broadleaf vegetation samples were collected monthly 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 groundlevel D/Q were required. Environmental Surveillance Program personnel met vegetation sampling requirements by maintaining two gardens inside the SITE BOUNDARY, Sectors J and R. These sampling locations (Figure 1-3, Table 2-6) provided a more conservative assessment of doses due to the higher deposition rates-(D/Qs) than would be measured at offsite

If such vegetabits were not available, samples of any vegetation with relatively broad leaves on which airborne radioactive particulate material might be deposited were sampled. The raw samples were then analyzed for gr.mma radionuclides and Iodine-131. 5

2.9.1 INTERPRETATIONS'AND TRENDS OF RESULTS
-Although some minor changes occurred from 1990 to 1991, as shown in Table 2-10, there was no need to modify the ESP. Also, there was no_ identified location which yielded _a calculated dose or dose commitment greater than those currently being calculated.
Results of the 1991 Land Use Census indicated land uses in the zero to 5-mile rea surrounding GGNS have remained basically the same , as'those reported in the 1989 and 1990 Annual Land Use Census. Table 2-11 presents _the 1991 Land Use Census data sheets. 2.9.2 DEVIATIONS FROM ThE ESP ESP personnel conducted the Annual Land Use Census ss required by GGNS Technical Specifications during 1991 without exception. 2.9.3 PROGRAM DESCRIPTION ESP personnel conducted an Annual Land Use Census, as required by GGNS Technical Specification 3.12.2. The purpose of the census i was:to identify changes in uses of land in unrestricted areas surrounding GGNS which would require modifications to the ESP or Offsite Dose Calculation Manual (ODCM). The most important criteria during the census were to determine location, in each of the 16 j meteorological sectors, of the nearest: o ' Residence o Animal-milked for human consumption o Garden of greater than 50_ m 2 (500 ft2) producing broadleaf . vegetation. i. 2 , RADEVN.RPT/SRREVFLR-2-47 i

3.1 SAMPL" llANDLING AND TREATMENT Once a representative sample is received by analytical laboratory, labcratory staff is responsible for properly treating and storing the sample. Environmental samples frequently regt. ire treatment prior to analysis. Treatment of the sample after it is received depends on sample and analyses to be performed. 3.1.1 Water Set 1.ca Genw ally, one-gallon water sarnples were acidified with five ml of concentrated llc 1 acid when co.11ected. Samples for tritium analyses should not be stored in polyethylene bottles for more than 3 or 4 months because water can evnporate through polyethylene. 3.1.2 Air Filters Air filtern were handled with care when heavy dust loadings were
-observed because particulate matter is easily removed from filter.
Air filters were normally received by ?aboratory in plastic containers; some extremely low-level analyses required analysis of the container as well as sample. 3.1.3 Milk Hilk samples were usually refrigerated until analyses could be performed. If analyses were delayed for more_than a few days, a preservative (formaldehy:!c) was added to inhibit bacterial growth and retard spoilage. Milk sanples analyzed for Iodine-131 had 100 m1 formaldehyde added, of- whic.h 40 m1 is r"armally added prior to shipment by customer, to avoid binding of the lodine t. ; may occur with smaller levels of formaldehyde. 9 l FADEVN.RPT/SRREVFLR-3-1
3.1.4 Soil and Bottom Sediment Soil and sediment samples were dried, pulverized and sieved before analysis. To ensure a homogeneous sample, thorough mixing was required. 3.1.5 Other Samoles Perishable sampics were preserved by refrigeration or freezing. Vegetatito and other samples may need to be dried, pulverined or ashed before or after analysis for long-term storage. _ 3.2 ANALYSIS OF AIR SAMPLES FOR GROSS ALPHA / BETA RADIONUCLIDES Air filters were counted in a low-background alpha-beta c ,unter at least 24 hours after collection in order to allow for decay of short-lived materials such as radon and thoron. Calculations of the results, two sigma error and lower limit of detection (LLD) were performed as indicated in the following: ALPHA RESULT = [(N/T)-(B/t)]/(2.22 V4E) > (pC1/m3) BETA RESULT = [(N/T)-(B/t)-(r)(N/T))/(2.22 V E) (pC1/m3) 3 TWO SIGMA ERROR = 1.96 J(N/T )+(B/t*)/(2.22 V E) (pC1/m3) LLD (pClim3) = 4.66 4(B)/(2.22 V'E t) where: N -= Gross counts of sample T = Number of minutes sample was counted < ) B = Counts of blank t = Number.of minutes blank was counted 2.22 = dpm/pCi V = Samplo aliquot size-(cubic meters) E z Counting efficiency-r n Ratio of alpha counts in beta counting (cross-talk) k RADEVN.RPT/SRREVFLR-3-2

I i 3.3 ANALYSIS OF WATER SAMPLES FOR GROSS ALPilA/ BETA RADIONUCLIDES Saction 3.3 describes process used to measure overall alpha-beta radionuclides of water saaples without identifying specific radioactive isotopo present. No chemical separation techniques were involved. Two hundred ml of sample war evaporated in a beaker at approximately 100*C, The residue was transferred and dried in a 2-inch stainless steel planchet. The planchets were counted for 100 minutes in a low-background alpha-beta counting system. Calculation of activity includes a self-absorption correction factor for counter efficiency based on weight of residue on each planchet. Calculations of the results, two sigma error and lower limit of detection (LLD) were performed as indicated in the following:

3.5 ANALYSIS OF SAMPLES FOR 10 DINE-131 4 Up to four liters of sample was thoroughly mixed with a stable lodine carrier solution. The sample was then passed through an anion exchange resin column to remove lodine f rom the sample. The lodine was then stripped from the I resin with a sodium hypochlorite solution, reduced with hydroxylamine hydrochloride and extracted into carbon tetrachloride as free iodine. It was then back-extracted into sodium bisulfite solution and was precipitated as silver iodide. The precipitate was weighed to determine chemical yield and mounted on a stainless stool planchet for low-level beta counting. The chemical yield was correctnd by m,asuring the stable lodide content of milk or water with a specific ion electrode. RADEVN.P?T/SRREVFLR-3-4. .

ANALYSIS OF SAMPLES FOR GAMMA RADIONUCLlDES 3.6.1 dj lk and Wat er A 3.5-11ter Marinelli beaker was filled with a representative aliquot of the sample. The sample was then counted for a minimum of 240 minutes, or until required LLDs were achieved, in a shicided Germanium-Lithium (gel 1) detector coupled to a computer-based data acquisition system which performed a pulse height analysis. A computer software program defined peaks by certain changes in slope of the spectrum. The program also compared energy of each neak with a library of peaks for radionuclide identification and then performed calculation using appropriate fractional gamma ray abur. dance, half life, detector efficiency and not counts in the peak region.

3.6.3 Soils and Sediments : 9o11s and sediments were oried at a low temperature (less than 100'C), loaded into a tared 1.0-liter Marinelli beaker and weighed. The sample was then counted for 240 minutes, or until required LLDs , were achieved, in a shielded GeLi detector as described in Section 3.6.1. 3.6.4 Charcoal Cartridges Charcoal cartridges were counted in a Marinelli beaker, with one to four cartridges positioned on the face of a GeLi detector and-up to seven cartridges on its side. Each detector was calibrated for both top and side positions and a counting efficiency determined. The Iodine-131 detection limit was determined for each charcoal , cartridge, assuming no positive results for Iodine-131, by utilizing smallest volume of air recorded for a cartridge within Marinelli RADEVN.RPT/SRREVFLR '3-6 _ _ _ . - _ _ . , _ - _ _ _ _ ._. _ . _ _ _ _ _ . _ . _ _ _ - _ . _ _ _ _ _ _ _ _ . . _ ._- _ . ~

l l 3.7 THERM 0 LUMINESCENT DRSIMETERS fTLDs,1 Environmental radiation doses were measured using TLD cards impregnated with calcium sulfate: dysprosium 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 cards were spread out in a single layer on a perforated metal tray and annealed for two hours at 250-260 C. After cooling, the cards were mounted in a card holder, nealed in a plastic protective holder _ and shipped for plauement in the field. Upon return from the field, TLD cards were read in a Toledyne Isotopes Model 8300 TLD Reader. After readout, cards were annealed again and irradiated with a known dose using a Radium-226 source encapsulated in an fridium needle and then read again to determine the card efficiency. The net exposure was calculated by the computer after in-transit exposure was subtracted. - 3.8 DATA REPORTING CONVENTIONS The mean of analytical results is as follows: E = I Xi / n - where: 5= Mean Xi = Individual sample results
, n= Number of sample results Rounding of cr.lculated values is accomplished by inspection of digits to the right of last reported digit wi+.h values less than 5 rounded down and values greater than 5 rounded up. When value equals 5, reported value is rounded to an even number.

6.1 J221 DATA
- Attachments I and II present data obtained by Entergy Services, Inc (ESI)
System Chemistry, formerly Arkanoas Power and Light's Tecinical Analysis Section and Teledyne Isotopes Midwest Laboratory on samples collected from January through December 1991.. Data was provided by ESI System Chemistry in monthly progress reports with exception of thermoluminescent dosimeters (TLDs). 4 Teledyne Is ' opes provided TLD data in quarterly reports. 1 Data presented in Attachments I and II is comparable to that encountered in previous years. 5.2 LOWER-LINIT OF DETECTION (LLD) In many analyses, the LLD achieved by ESI System Chemistry sas lower than c maximum'LLD permitted by GGNS Technical Specification Table 4.12.1-1. Factors such as unavoidable small sample size, background fluctuations, presence of interfering radionuclides or other uncontrollable circumstances may cause Technical Specifications' LLD to be unachievable, floweve r , in 1991 all Technical Specification LLDs were achieved. 6.3 REPORTING LEVELS-F Radioactivity attributable to GGNS was found in the dischcrge basin water, sewage sludge and barge slip sediment. Ilowever, no reporting levels for radioactivity concentration in environmental samples, as outlined in Technical [. Specifications Table 3.12.1-2 when averaged over anyLcalendar quarter, wero l L- equaled or exc eeded due' to GGNS ef fluents. Que radionuclide (Chromium-51), l which is not listed in GGNS Technical Specifications Table 3.12.1-2, was detected during 1991 -in the barge slip sediment. Iloweve r , the quantity detected was not capable of causing a dose to a member of the public exceeding calendar year limits of Technical Epacifications 3.11.1.2 of s 3 millirem total l RADEVN.RPT/SRREVFLR-6-1

body and 5 10 mil'.irem any organ as'calculatedfby the following generalized equation found in Regulatory Guide 1.109, Appendix A: R = (40) (C) (U) (D) (W) where: R = Annual dose to skin or total body in mrem / year; 40 = Area-mass conversion factor given in Appendix A of Regulatory Guide 1.109 in Kg/m2; C = 1991 maximum radionuclide cuncontration (329) inspC1/kg; U = Maximum exposure time given in Table E-5 of Regulatory Guide 1.109 (67 hours for a teenager); D = External dose conversion factor for standing on contaminated

ground given in Table E-6 of Regulatory Guide 1.109'(.2 60'E-10 for skin and .2.20 E-10 for total body)' in mrem /hr per pCi/m2, and W = Shore-width factor (0.1) given in Table A-2 of Regulatory Guide 1.109. The maximum annual dose to a teenager spending 67 hours at the barge slip shoreline was calculated to be appreximately .000023 millirem to the skin and
.000019 millirem to the total body. Therefore, the radiological impact to environment or public from Chromium-51 is insignificant and no Radiological Monitoring Program Special Reports were required. ,
6.4 SAMPLING DEVIATIONS Samples required by GGNS Technica2 Specification 3.12.1 were collected within the scheduled period unless noted otherwise in Attachments I and II. L Sample deviations at locations required by GGNS Technical Specifications are discussed in Sections i
- through 2.7. These sections provide more
. explanation concerning reasons why samples were missed and describes corrective i
action where appropriate. 6.5 .RADI0 ACTIVITY NOT ATTRIBUTABLE TO GGNS Radioactivity attributable to other sources has been detected twice by the i .GGNS EST. In early 1980, the 25th Chinese nuclear test explosion was detected. ! In 1986, the radioactive plume release due to reactor. core degradation at L Chernobyl Nuclear Power Plant was detected.

6.6 SAMPLING RELOC'IIDS Sampling locations did not change in 1991. Therefore, there was no need to identify new locations and report circumstances of unavailability in the Semiannual Radioactive Effluent Release Report. 6.7 QQMPARISON TO FEDERAL AND STATE PROGRAMS Data from the GGNS ESP was compared to federal and state r..onitoring programs as results became available. The federal monitoring program used for comparison was the U.S. Nuclear Regulatory Commission (NRC) TLD Direct Radiation Monitoring Network. Ine state programs are conducted by the Mississippi State Department of Health, Divisian of Radiological Health, and
?.he Louisiana Department of Natural Resources, Nuclear Ener:9 Division.
The latest available results from the NRC TLD Network have been comparable to those from the GGNS ESP. These results cover 33 TLD locations, 16 of which are collocated. On the average, collocated TLDs have produced similar results. Prior to 1991, no change in collocated TLD results has been attributed to GGNS operation. apdiological menitoring 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 1991, all three programs have obtained results that are within similar ranges. The only common location l l where radioactivity attributable to GGNS has been detected is the GGNS barge l slip. Barge slip sediment results were above background due to GGNS effluents. + l l RADEVN.RPT/SRREVFLR-6-3 1 i

**1 A new efficiency curve was constructed using a blank EPA plastic air filter.
Efficiencies calculated using this air filter- geometry were approximately 30% higher than previous geometries using air particulate filters.
**2 Blind water samples contain several isotopes which have different beta energies. .The efficiency curve for beta in water was constructed using Cs-137 Because the strontium isotopes have different beta energies than Cs-137, the results may not always agree with the standard beta in water efficiency using only Cs-137.
**3 The results submitted by System Chemistry for Total Potassium (K) were less than the L
lower control unit' established by EPA- for this sample. System Chemistry will investigate possible sources of error within the gamma spectrometer ef ficiency curves and the calculations used to convert K-40 measurements into Total Potassium results. The results of these investigations will be included in the next monthly report. 8 It_ should be noted that the maan result submitted by 63 laboratories whose results were included in the Grand Average was 1.5 standard deviations below the value used by the EPA as the "known value" for Total Potassium for this cross-check sample. Of - the results classified as outside the control limits by EPA, 17 were outside of
- the lower control limit set by the EPA while only 3 results were outside of the I
higher control limit. The submitted results were drastically shifted below the EPA-l- established "known value". A request will be made to EPA to recheck.the published "known value" for Total Potassium of this sample. Results of this inquiry will be included in the next monthly report after receipt of a reply from the EPA. y The U.S. EPA was contacted and confirmed that the ~ "known value" for Total Potassium L was correct. An independent experiment was developed to measure Total Potassium using a known mass on Potassium Nitrate dissolved in 3.5L of water. The experimented value was calculated to be 0.993 of the theoretical value. l
