SUMMARY

,The Annual' Radiological Environmental Operating' Report (ARE0R) presents ..

q -

y

' data obtained through analyses'of environmental samples collected for.the Grand- ,

Gulf Nuclear Station (GGNS) Environmental Surveillance _ Program'(ESP)- for the period January 1, 1988 through December 31, 1988.-

An assessment of plant: operation by' ESP personnel: using ARE0R' data concluded that no significant; relationship exists between GGNS operation and

'effect on the environs: surrounding the Plant. .'As in previous ~ years,, radiation levels.in-the environment were undetectable in-many cases and at or near background levels in significant pathways' associated with GGNS. Therefore, ESP personn'el concluded that GGNS operation hasihad'no h' armful: effects nor resulted-in any irreversible damage to the environment.

l INTRODUCTION l

1.1 SCOPE The Annual Radiological Environmental Operating Report (ARE0R) presents data obtained through analyses of environmental samples collected 1

for the Grand Gulf. Nuclear Station (GGNS) Environmental Surveillance i i

Program (ESP) for-the period January 1,1988.through December 31, 1988.

]

The ARE0R fulfills the requirements of GGNS Technical Specifications 6.9.1.6 and 6.9.1.7. )

I 1.2 PURPOSE AND DESIGN' CRITERIA 0F THE ENVIRONMENTAL l SURVEILLANCE PROGRAM (ESP)

The purpose of the ESP is:

o To measure radiation levels and tneir variations in i 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 and techniques o To detect effects, if any, of GGNS operation on the environmental radiation levels and concentrations.

The design criteria for the ESP are:

o To analyze important pathways for anticipated types and quantities of radionuclides released into the environment o To consider the possibility of a buildup of long-lived radionuclides in the environment and identify physical and biological accumulations that 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 l environment with radioactive releases from station operation.

i 1.3 DOSE PATHWAYS ASSOCIATED WITH GGNS The mos't significant environmental dose pathways from a nuclear power' station are direct dose from gaseous effluent'and thyroid dose due to-the ingestion of milk. GGNS operations are expected to.have little, if any, q impact by these pathways due'to the very low' levels of radiation released,

' the remote location'of the ' station and the absence ~ of milking animals l

within five miles. 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. i 1.4 PREVIOUS DATA COMPARIS0N

.l A comparison by ESP personnel of 1988 ESP results to preoperational studies, operational controls and previous AREORs shows no significant j changes. As in previous years, ESP results remained at or near background levels. Such results confirm that GGNS effluent controls and equipment are performing satisfactorily.

P.1.1 INTERPRETATIONS AND TRENDS OF RESULTS-Air particulate and Iodine-131 results for 1988 were similar to those obtained in previous years of the operational and preoperational ESP. Results from 1988 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.

Average or mean values for air particulate indicator and control locations produced similar values in 1988. This I

emphasizes the fact that air particulate levels are at background levels and have been uninfluenced by the operation of GGNS. This point is illustrated in Figures 2-1 and 2-2. These figures show j that the control location and indicator locations had similar average values during 1988 and for the past four years.

Yearly average gross beta-emitting radionuclides activity from 1979 through 1988 in Figure 2-3 further emphasizes that GGNS has had no influence on ambient radiation levels. This figure shows a l ten year trend for each indicator location compared to the control location. Control and indicator values were equivalent over the )

ten year period which includes operational and preoperational data.

An independent verification of the accuracy of GGNS results has been made through the use of Mississippi State Department of Health and GGNS collocated air sampling stations and is

. illustrated in Figure 2-4. This figure indicates that consistent, valid data is being collected based on the similarity of results.

2.1.2 DEVIATIONS FROM THE ESP i .

! Mechanical pump failure caused two air samples from AS-8 to be missed in 1988. 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 GGNS Environmental Surveillance Program used eleven .j i

continuous air monitors to provide gross beta-emitting ')

I radionuclides, gamma-emitting radionuclides and radioiodine )

I activity measurements by the airborne exposure pathway. These l

l monitors were placed at distances from 0 to 18 miles, as shown in )

i Figures 2-5 through 2-7 and Table 2-1. Five of the air samplers were used to meet the requirements of GGNS Technical Specification 4.12.1. Placement of the five required monitors is as follows:

I o Three near the SITE BOUNDARY in areas of the highest -l calculated annual average groundlevel D/Q values 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 samplers were located in areas which provide additional data for the ESP.

The samplers were placed one meter above the ground in weatherproof 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 per minute. Filters and cartridges were changed J22ARE0R88082601 3

weekly and analyzed for gross. beta-emitting radionuclides and j

\

radioiodine activity, re'spectively. In addition, the filters were 4

composited quarterly and analyzed for gamma-emitting ,

I radionuclides.

2.2.1 INTERPRETATIONS AND TRENDS OF RESULTS Gamma radiation dose in 1988 was measured with thermoluminescent dosimeters (TLDs) on a quarterly schedule.

There was no significant difference in 1985 through 1988 average dose rates as illustrated in Table 2-2. -l

)

Direct radiation dose to the public from 1983 through 1988 is )

presented in Table 2-3. Quarterly results in 1988 were less than one mrem. As indicated in Table 2-3, the operation of GGNS has had minimal impact on direct radiation dose to the public.

Average or mean values for particulate indicator and control locations for 1988 produced similar values. As with the air.

analytical results, this indicates no effect on' ambient radiation levels due to the operation of GGNS. This conclusion is represented in Figures 2-8 and 2-9 of 1979 through 1988 yearly average TLD results and 1987 through 1988 quarterly average TLD results, ,

respectively. These figures also indicate that ambient radiation levels have remained at or near background levels.

An independent verification of the accuracy of GGNS TLD results has been made through the use of NRC and GbNS collocated TLDs. The NRC and GGNS collocated TLD results for the eleven most recent quarters available are presented in Figure 2-10. This figure indicates that consistent, valid data is being collected 4 based on the similarity of TLD results.

i 2.2.2 DEVIATIONS FROM THE ESP Five TLDs required by GGNS Technical Specifications were lost in the field during 1988. These losses were caused by vandalism and flooding of the Mississippi River. TLD losses of this type I l

are characteristic of other TLD programs. The 1988 recovery rate for TLDs required by GGNS Technical Specifications was 97% (155 of 160) and is comparable with other TLD programs.

2.2.3 PROGRAM DESCRIPTION Ambient radiation in the environment surrounding GGNS was measured with 94 TLD cards (calcium sulfate: dysprosium phosphor i'

dosimeters) to provide a quantitative measurement of the area l

radiation levels. These environmental TLDs were placed at I 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 meter above the ground. The dosimeters were collected quarterly.

The criteria used in establishing TLD locations are summarized below:

i o GGNS Technical Specification 4.12.1 requires 40 of the 94 l TLDs to be positioned as outlined below:

- An inner ring of 16 stations in the general area of l 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 TLD in each meteorological sector Eight TLDs located in special interest areas such as population centers and residences or utilized as controls.

J22AREOR88082601 19

o Twenty-four permanent TLD stations were established at the protected area boundary.

o The remaining 30 TLDs were located in areas away from the GGNS site. -These TLDs were used to gather supplemental and supporting data for determining direct radiation dose.

In summary, the TLD locations can be grouped as follows:

I 2.3.1 INTERPRETATIONS AND TRENDS OF RESULTS 'l l

Milk samples within five miles of the GGNS site were j unavailable in 1988 due.to the absence of milking anirnals. Milk samples from the Alcorn State University control location were.

collected bimonthly and analyzed for Iodine-131 and gamma-emitting radionuclides. Neither gamma-emitting radionuclides nor Iodine-131 concentrations were detected in Alcorn milk samples. i As in previous years, no radioactivity attributable to GGNS I

was detected in milk samples, i l

2.3.2 DEVIATIONS FROM THE ESP l 1

Milk samples were collected from a control location at Alcorn State University (Sector K, 10.5 miles). However, as noted )

{

above, milk samples were unavailable within five miles (8 km) of l GGNS in 1988. As a result, vegetation samples were collected to monitor the ingestion pathway.

Milk collected on November 9, 1988 exceeded the maximum allowable LLD for Iodine-131 of 1 pCi/1 due to analysis delay.

An increase in administrative controls prevented this problem from recurring in 1988. l 2.3.3 PROGRAM DESCRIPTION When available, milk samples were collected in the vicinity of GGNS for the measurement of radioactivity by the ingestion-exposure pathway. GGNS Technical Specifications required sample collection from milking animals in three locations within a five km distance having the highest dose potential. If there were none, then one sample was required from milking animals in each of three areas, between distances of from five to eight km, where J22ARE0R88082601 38

U -1 L l J

l doses were calculated' to be greater than one mrem per year. Also- ,

required was-one control sample at a distance of from 15-30 km.

When available, samples were r.ollected semimonthly when animals were on pasture, monthly at other times.

A control milk sample was collected semimonthly in 1988 from j the Alcorn State Universitj Dairy (Table 2-5) to' establish l l

background data. But, milk animals were unavailable in 1988 i within eight km (five miles) of GGNS. Section 2.5, Vegetation, addresses the unavailability of milk samples within the vicinity. )

l 2.5.1 INTERPRETATIONS AND TRENDS OF RESULTS 1

Analytical results for vegetation,in'1988 and previous years have shown no data which was attributable to the operat'on of j GGNS. Radiation levels for vegetation continue to remain at background levels.  !

2.5.2 DEVIATIONS FROM THE ESP

^1 Vegetation samples required by GGNS Technical Specifications were collected and analyzed during 1988 without exception.

2.5.3 PROGRAA DESCRIPTION Broadleaf vegetation samples were collected in the vicinity of GGNS 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 ar.nual average groundlevel D/Q were required, because milk samples within five miles were not available.

Environmental Surveillance Program personnel met vegetation sampling requirements by ma'.'ntaining two gardens inside the SITE BOUNDARY, Sectors J and R. These sampling locations (Table 2-7) provided a more conservative assessment of doses due to the higher deposition rates (D/Qs) than would be measured at offsite sampling locations.

The GGNS Technical Specifications also required control samples of each of the similar types of onsite vegetation 15-30 km f rom the site when milk sampling is not performed. To fulfill l this requirement, a control vegetation sample location has been I

l established in Sector K at Alcorn State University (Table 2-7).

J22ARE0R88082601 48

The preferred source of broadleaf vegetation was green-leafy vegetables suitable for human consumption. If such vegetables 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 fo' gamma-emitting radionuclides and Iodine-131.

J22ARE0R88082601 51

2.6.1 INTERPRETATIONS AND TRENDS OF RESULTS Sediment samples were collected semiannually in 1988 and analyzed for gamma-emitting radionuclides as required by the GGNS Technical Specifications.

An analytical results summary for 1985 through 1988 barge slip sediment samples is provided in Table 2-8. A comparison of {

1985 through 1988 average concentrations is provided in Figure 2-12. These radionuclides were not detected prior to 1985. ]

]

Their presence since 1985 may be attributed to build up of very i small amounts of particulate.

As shown in Table 2-8, radionuclides concentrations in barge slip sediment appear to be decreasing. However, previous sampling 1

of the barge slip sediment revealed a wide range of concentrations. No definite correlation between radionuclides l

concentrations and plant operating levels, effluent releases or '

river elevation has been found by ESP personnel.

2.6.2 DEVIATIONS FROM THE ESP Sediment samples required by GGNS Technical Specifications were collected and analyzed during 1988 without exception.

2.6.3 PROGRAM DESCRIPTION Sediment samples were collected semiannually at the following locations (Table 2-9):

o River shoreline where the plant effluent is discharged (Barge Slip)

J22ARE0R8808c601 52

o Downstream of the barge slip in the vicinity of the Hamilton Lake outfall (indicator location) o -Upstream from the influence of GGNS discharges (Upper Grand Gulf Landing)

The only sediment sample require ( by GGNS Technical Specifications is the downstream location (indicator). The upstream location would be classified as a control and the barge slip as'an indicator.

I Sediment samples were collected near the shoreline from the top one-inch layer of sediment. After foreign objects were

. discarded, the samples'were transferred to clean, labelled containers. The samples were then analyzed for gamma-emitting radionuclides.

shown in Table 2-11, there was no need to r.o'dify~the ESP. Also, there was no location identified which yielded a calculated dose or dose commitment greater than those currently being calculated.

The results of the 1988 Land Use Census indicated the land

.uses in the zero'to 5-mile area surrounding GGNS have remained  ;

basically the same as those 'eported r in the 1986 and 1987 Annual' l

, Land Use Census. The.1988 Land Use Census data sheets are presented in Table 2-12.

Environmental Surveillance Program personnel also' conducted'a j survey in 1988 to locate the nearest potabl' water system south of the GGNS discharge point that uses the Mississippi-River as a J22ARE0R88082601 64

unrestricted areas surrounding GGNS which would require I

modifications to the ESP or the Offsite Dose Calculation Manual (0DCM). The most important criteria during the census were to determine the location, in each of the 16 meteorological sectors, of the nearest: ,

APPENDIX A INTERLABORATORY COMPARISON PROGRAM RESULTS The results in Table A-1 form Arkansas Power & Light's (AP&L) l participation in the environmental sample crosscheck program for milk, water and air filter samples from January through December 1988. This {

program has been conducted by the U. S. Environmental Protection Agency '

(EPA) Intercomparison and Calibration Section, Quality Assurance Branch, Environmental Monitoring and Support Laboratory, Las Vegas, Nevada.

AP&L Technical Analysis Section has participated in interlaboratory comparison (crosscheck) programs since its quality control program began in January 1976. These programs are operated by agencies which supply ,

environmental-type samples (e.g., milk or water) containing radionuclides concentrations known to the issuing agency but not to participant laboratories. This program provides an independent check on the ~j laboratory's analytical procedures and any possible problems. ]

1 Participant laboratories measure the concentration of specified I radionuclides and report them to the issuing agency. Several months later, the agency reports the known values to the participant laboratories and specifies control limits. Results consistently higher

]

or lower than the known values or outside the control limits show a i need to check the instruments or procedures used. )

i The results in Table A-2 were obtained by Teledyne Isotopes' Midwest I Laboratory for thermoluminescent dosimeters (TLDs) during the periods 1976, 1977, 1979, 1980, 1984, 1985 and 1986 through participation in the Second Third, Fourth, Fifth, Seventh and Eighth International Intercomparison of Environmental Dosimeters under the sponsorships listed in Table A-2. In 1987 and 1988 the above intercomparison was not conducted.

• LT : Less Than '

• • Greater Than i 2 Sigma

• • • Greater Than i 3 Sigma (I I-131 was analyzed by several methods for quantification including gamma spectroscopy of the liquid milk (3-.7 liters); anion chromatography _(with precipitate of silver iodide on 2-inch diameter planchet) followed by beta counting using a low-background alpha / beta detection; and also analyzing the precipitate.by gamma spectroscopy. All three methods yielded results varying 6-9 pCi j per liter.

In past EPA intercomparison studies for low-level I-131, the standard deviation was 67 percent of the known value (i.e., 9 6, where 6 is one sigma). The standard deviation has now been lowered to 10 percent, thereby increasing performance in accuracy 7-fold.

New efficiency curves for I-131 were calculated June 20, 1988 and the use of a new low-background alpha / beta detector began.

(2) Efficiency calculations for gross alpha values for air particulate filters have been refigured, resulting in higher alpha efficiency values. Future gross alpha values should agree with EPA air filter j results.

l (3)As of August 18, 1988, no environmental radiological monitoring j program requires analysis for gross alpha activity. In the future, gross alpha activity will not be reported.

(4) Presently the cause for exceeding the three standard deviation has not been determined. However, EPA results are being evaluated  ;

for further determinations. '

DATA REPORTING CONVENTIONS i The results.of the' Environmental Surveillance Program for 1988 are summarized in Tables.4-1 and 4-2 of the 1988' Annual Radiological Environmental Operating Report:(ARE0R). Only results from'the sampling locations; required by GGNS Technical. Specifications,fwhich'are identified in Section 2.0 of the 1988 AREOR, were utilized to develop Table 4-l'. Table 4-2 include results from all sampling-locations, not j just those required by Technical Specifications. Also, Tables 4-1 and i 4-2 do not. include- duplicate sample. results.' j Indicator and control locations-for' Table 4-1 are as designated-by the

-GGNS. Technical Specifications and summarized in Table 4-3. : Indicator and control locations for Table.4-2 are listed in Table 4-4. For determining the ranges' and means for indicator.and control locations, values reported as less than were'not used.

Th< mean' of analytical results given in the. Data Summary Tables is:

X = I Xi / n Where _

X = Mean Xi = Individual sample results n = Number-of results within the group 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.

]

Calculation methods for 2 sigma counting error associated with analytical results and Lower Limits of Detection (LLD) are given in .

Section 3.0 for each type of analytical procedure. Analytical results  !

given in Attachment II which are less than the~2 sigma counting error ere reported as less than the LLD calculated for that sample. . Analytical l results greater than the 2 sigma counting error are reported along.with  !

the associated 2 sigma counting error as a plus_or minus (i) term. j Calendar quarters-are considered to be the following time periods:

3.1 SAMPLE HANDLING AND TREATMENT Once a representative sample is' received by the contract laboratory, the laboratory staff is responsible for properly treating and storing the sample. Environmental samples frequently require treatment prict to analysis. Treatment of the sample aftar it is received depends on the sample and the analyses to be performed on it.

3.1.1 Water Samples Generally, one gallon water samples were acidified with five ml of concentrated hcl acid when collected. Samples for tritium analyses were normally not-stored in polyethylene bottles for more than 3 or 4 months because water can evaporate through the polyethylene. Carrier or complexing agents were added to prevent absorption of trace metals by the storage containers.

3.1.2 Air Filters Air filters were handled with care when heavy dust loadings were observed because particulate matter is easily removed from the filter. Air filters were normally received by the laboratory in plastic containers; .ome extremely low-level analyses required analysis of the container as well as the sample.

3.1.3 Milk Milk samples were usually refrigerated until analyses could be performed. If analyses were delayed for more than a few days, a preservative (formaldehyde) was added to inhibit bacterial growth I

and retard spoilage. Milk samples that were analyzed for Iodine-131 had 100 m1 formalin added to avoid binding of the l iodine that may occur with smaller levels of formaldehyde.

1 1

l 3.1.4 3eil and Bottom Sediment Seil and sediment samples were dried, pulverized and sieved i

befor e analysis. To ensure a homogeneous sample, thorough niixing l was requ'. S '

3.1.5 Other Samples Perishable samples 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.

3.2 GROSS ALPHA / BETA-EMITTING RADIONUCLIDES ANALYSIS OF AIR PARTICULATE SAMPLES _

Air filters were counted in a low-background alpha-beta counter at least 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> after collection in order to allow for decay of short-lived materials such as radon and thoron.

Calculations of the results, the two sigma error and the lower limit of detection (LLD) were performed as indicated in the following:

ALPHA RESULT = [(N/T)-(B/t)]/(2.22 V E)

(pCi/m3)

BETA RESULT = [(N/T'-(B/t)-(r)(N/T)]/(2.22 V E)

(pCi/m3)

TWO SIGMA ERROR = 2 4(N/T2)+(8/ta)/(2,22.y.E)

(pCi/m3)

LLD (pCi/m3) = 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 b' lank was counted 2.22 = dpm/pCi V = Sample aliquot size (cubic meters)  !

E = Counting ~ efficiency r = Ratio of alpha counts in beta counting (cross-talk)

3.3 DETERMINATION OF GROSS ALPHA-EMITTING RADIONUCLIDES AND/0R

! GROSS BETA-EMITTING RADIONUCLIOE ACTIVITY IN WATER SAMPLES i

Section 3.3 describes the process used to measure the overall 1

! alpha-emitting radionuclides and beta-emitting radionuclides of water samples without identifying the specific radioactive isotope present.

i No chemical separation techniques were involved. Two hundred ml of the l sample was evaporated in a beaker at approximately 100 C. The residue l 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.e self-absorption correction factor for counter efficiency based on the weight of residue on each planchet.

Calculation of the sample activity or of the minimum detectable activity was performed as indicated in the following:

ALPHA RESULT = [(N/T)-(B/t)]/(2.22 V E)

(pCi/1)

BETA RESULT = [(N/f)-(B/t)-(r)(N/T)]/(2.22 V E)

(pCi/1)

TWO SIGMA ERROR = 2 4(N/T2)+(8/t2)/(2.22 V E)

(pCi/1) 3 LLD (pCi/1) = 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 = Sample aliquot dize (liters)

E = Counting efficiency r = Ratio of alpha counts in beta counting  ;

')

l i If the net activity (N'/T-B/t) was equal to or less than the counting I

l error, the activity on the collection date was below the limits'of>-

detection and was designated less than the lower' limit of detection (LLD).

3.4 ANALYSIS OF WATER SAMPLES FOR TRITIUM Five milliliters of water was added to 15 ml of' liquid scintillation solution in a 25 ml vial. The sample was inserted into a liquid scintillation spectrometer and counted'for 300-500 minutes.

Calculations of the results, the~two sigma ~ error and the lower limit of detection (LLD) were' performed as indicated in'the following:

RESULT = [(N/T)-(B/t)]/[(2.22 V E) exp(-Mt 2)]

(pCi/1)

TWO SIGMA ERROR = 2 J(N/T2)+(B/t2)+[(2.22 V E) exp(-Mt 2 )]

(pCi/1)

LLD (pCi/1) = 4.66 6 2.22 E V t exp(- Mtz) 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 = Sample aliquot size (1)

E = Counting efficiency exp(-Mt 2) = Decay correction where at2 is time elapsed between collection of sample and date of counting.

3.5 ANALYSIS OF SAMPLES FOR 10 DINE-131 Up to four liters of. sample was thoroughly ~ mixed with a stable iodine carrier solution. The sample wa's then_ passed thrcugh an' anion exchange column to remove iodine from the sample. The iodine was then stripped from the resin with a sodium hypochlorite solution, reduced with.

hydroxylamines hydrochloric:1e and extracted into carbon tetrachloride as J22ARE0R88082601.- 3-4 1

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 steel planchet for low-level beta counting. The chemical yield was corrected by measuring the stable iodide content of the milk or the water with a specific ion electrode.

Calculations of the results, two sigma error and the lower limit of detection (LLD) in pCi/1 were performed as indicated in the following:

)

RESULT = (N/t-B/t)/[(2.22 E V Y)exp(-Mt 2)] i (pCi/1)

TWO SIGMA ERROR = (1.96 J(N/t2)+(8/t2)+[(2.22 E V Y)exp(-Mt2 )]

(pC1/1)

LLD (pCi/1) = (4.66 4(B/t2)+[(2.22 E V Y)exp(-Mt2 )]

where: N = Total counts from sample (counts) t = Counting time for sample (min)

B = Total counts of blank (counts)  ;

2.22 = dpm/pCi i E = Efficiency of the counter for Iodine I-131 corrected for self absorption effects  ;

V = Volume of sample analyzed  ;

Y = Chemical yield of the amount of sample i counted exp(-Mt 2) = Decay factor from the time of collection to the counting date 3.6 GAMMA SPECTROMETRY OF SAMPLES i

3.6.1 Milk and Water i l

A 3.5-liter Marinelli beaker was filled with a representative 4 aliquot of the sample. The sample was then counted for a minimum of 240 minutes, or until the required LLDs were achieved, in a shielded Germanium-Lithium (GeLi) detector coupled to a computer-based data acquisition system which performed a pulse height analysis.

J22ARE0R88082601 5

l A computer software program defined peaks by certain changes in the slope of the spectrum. The program also compared the energy of each peak with a library of peaks for radionuclides identification and then performed the radioactivity calculation l l

using the appropriate fractional gamma ray abundance, half life, l l

detector efficiency and net counts in the peak region. J 3.6.2 Vegetation, Food and Garden Crops, and Fish A maximum quantity of undried vegetation, food or garden crop sample was loaded into a tared 3.5-liter Marinelli beaker and weighed. The sample was then counted for a minimum of 200 minutes, or until the required LLDs were achieved, in a shielded GeLi 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 beaker and weighed. The sample was then diluted with deionized water to weigh 3.5 kg and counted for a minimum of 240 minutes in a shielded GeLi detector as described in Section 3.6.1. "

3.6.3 Soils and Sediments Soils and sediments were dried 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 at least four hours, or until the 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 J22ARE0R88082601 6

\

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 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.

3.6.5 Air Particulate The 12 to 14 (depending on the calendar quarter) air

~

particulate filters 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 LLDs 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 pCi/ volume or pCi/ mass.were performed as indicated in the following:

RESULT = (S-B)/[(2.22 T E V F) exp(-Mt2)]~

TWO SIGMA ERROR = (1.96 VS+BT/[(2.22 T E V F) exp(-Mt2 )3 LLD = (4.66 457[(2.22 T E V F) exp(-Mt2 )3 y

where: S= Area, in counts, of sample peak and background (region of spectrum of. interest).

B= Background area, in counts, under sample peak, determined by a linear. interpolation of-the representative backgrounds on either-side of the peak 2.22 = dpm/pCi

)

impregnated withl calcium sulfate: dysprosium' phosphor sealed in plastic' protective holders. These TLD cards had fou main' readout areas utilized.

in calculating dose rates'and four reserve areas as a backup dosimeter. I Prior to installation the cards were spread out in a. single layer on.

a perforated metal tray and annealed for one. hour at 250-2606C. After cooling, the cards were mounted in a card' holder.. sealed in a plastic-  !

1 protective holder and shipped- for placement in the field.

Upon return from the field, the TLD cards'were-read in.a'Teledyne ,

Isotopes Model 8300 TLD Reader. - After readout, the cards were annealed again and irradiated with a known dosefusing a Radium-226 source encapsulated in an iridium needle and then read again to determine the I 1

card efficiency. The net exposure was calculated by the computer after .]

in-transit exposure was subtracted. The LLD for environmental ILDs is 1 mrem / quarter.

5.1 CROSSCHECK PROGRAM RESULTS The results of Arkansas Power & Light's-(AP&L) Technical Analysis Section Crosscheck Program are provided in Attachment II, 1988 Environmental Sampling and Analytical Report. Appendix A, Table A-1, of Attachment II contains the results obtained through AP&L's participation in the EPA Crosscheck Program. Graphs of AP&L's intercomparison results 1

are provided in Figure 5-1. This figure indicates that consistent, valid I

data is being reported based on the similarity of EPA and AP&L results.

a Teledyne Isotopes Midwest Laboratory provided thermoluminescent i J

dosimeter (TLD) analytical capabilities. Appendix A, Table A-2, of Attachment II contains the most recent results' obtained through Teledyne's participation in the International Intercomparison of Environmental Dosimeters. i 5.2 DUPLICATE SAMPLES Results for duplicate samples of water, milk, fish, sediment and ]

vegetation media submitted by GGNS to AP&L are included in Attachment II.

1 ,

These results may be found in the appropriate tables and are identified by the suf fix (b) accompanying the laboratory nJmber. The results of the ESP i

duplicate sampling for 1988 are summarized in Table 5-1.

i A graph presents results for duplicate TLDs from 1985 through 1988 in Figure 5-2. This figura, 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.

7" SECTION 6.0 1988 SAMPLING AND ANALYTICAL RESULTS i

.r J22ARE0R88082601 1

't.

I i

i 6.1 1988 DATA i Attachment-II, 1988 Environmental Sampling and Analytical Report,

-presents data obtained by Arkansas Power and Light's (AP&L) Technical Analysis Section and Teledyne Isotopes' Midwest Laboratory on samples 1

collected from January through December'1988. With the exceptionLof thermoluminescent dosimeters (TLDs), data was provided by AP&L in monthly progress reports. Teledyne Isotopes provided TLD data in- quarterly reports.

Data presented in Attachment II is comparable to that encountered in' previous years and is indicative of what is expected in environmental

-i media of this type.

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. If factors such as unavoidable small sample size, background fluctuations, the presence of interfering radionuclides or other uncontrollable circumstances caused the Technical Specifications' LLD to be unachievable, the contributing factors'are identified and described by footnotes in Attachment II. I 6.3 REPORTING LEVELS i

Radioactivity attributable to GGNS was found in the discharge basin water, Basin B sediment and barge slip sediment. However, no reporting levels for radioactivity concentration in environmental samples, as  !

outlined in Technical Specifications Table 3.12.1-2 when averaged over any calendar quarter, were equaled or exceeded due to GGNS effluents. One radionuclides (Chromium-51), which is not listed in 'the GGNS Technical Specifications Table 3.12.1-2, was detected during 1988 in the barge s'l ip l.

J22ARE0R88082601 1

sediment. However, based on the quantity detected was not capable of causing a 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 Mu.itoring Program Special Reports were j required.

6.4 SAMPLING DEVIATIONS Samples requireo by GGNS Technical Specification 3.12.1 were collected within the scheduled period unless noted otherwise in Section l 2.0, List of Missing Samples, Attachment II. The List of Missing Samples summarizes the sample types, locations, collection dates and reasons for sample deviation. However, two sampling locations (Trimble Cistern and GGMP Well) did change in 1988 and are discussed below in Section 6.6.

I Sample deviations at locations required by GGNS Technical '

Specifications are discussed in Section 2.0. Sections 2.1 through 2.7 .

l provides more explanation concerning reasons why samples were missed and describes corrective action where appropriate.

)

6.5 RADI0 ACTIVITY NOT ATTRIBUTABLE TO GGNS Radioactivity from sources other than GGNS were not detected in 1988.

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 due to reactor core degradation at the Chernobyl Nuclear Power Plant was detected.

i J22ARE0R88082601 2

6.6 SAMPLING RELOCATION Two sampling locations changed in 1988 and were reported in the Semiannual Radioactive Effluent Release Report. Listed below is a summary of the change.

o Trimble Cistern (Sector E, 0.5 miles) is no longer in service and  !

was replaced by the next closest available continuous service collection location (McGee, Sector A, 0.9 miles). Sampling of the McGee Cistern began on January 9, 1988.

o The Grand Gulf Military Park (GGMP, Sector A,1.5 miles) well was abandoned. Water for the GGMP is now supplied by a community water supply well located four miles from GGNS. The GGMP well was )

replaced by the next closest available collection location (Arnold Acres Trailer Park, Sector J, 1.1 miles (inactive)). Sampling of the Arnold Acres well began on September. 29, 1987.

6.7 COMPARISON TO FEDERAL AND STATE PROGRAMS .

1 Data from the GGNS ESP was compared to federal.and state monitoring orograms as the results became available. The federal monitoring programs used for comparison include the U.S. Nuclear Regulatory Commission (NRC)

TLD Direct Radiation Monitoring Network and the U.S. Environmental Protection Agency (EPA) Environmental Radiation Ambient Monitoring System (ERAMS). 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.

The latest available results from the NRC TLD Network have been comparable to those from the GGNS ESP through June 1988. These results cover 33 TLD locations, 16 of which are collocated. On the average, J22ARE0R88082601 3 l

t - - - - - - ---- _-

collocated TLDs have produced similar results. Quarterly results normally range between 13 and 25 mR/ quarter. Prior to June 1988, no change in collocated TLD results has been attributed to GGNS operation.

The ERAMS is comprised of nationwide sampling stations. The Mississippi sampling locations involved are normally Jackson and Port Gibson. The major emphasis of ERAMS is toward identifying trends in the accumulation of long-lived radionuclides in the environment. The latest l

available results from ERAMS and the GGNS ESP through March 1987 have not indicated the accumulation of long-lived radionuclides attributable to GGNS.

Radiological monitoring by Mississippi & 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 1988, all three programs have obtained results that are within similar ranges. The only l 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.

6.8 UNAVAILABLE RESULTS Analytical contractor results were received in adequate time for inclusion. No missing results were identified during ESP personnel's I

review of these results, unless noted otherwise in Section 2.0, List of Missing Samples, Attachment II.

6.9 HARMFUL EFFECTS OR IRREVERSIBLE DAMAGE l 1

No harmful effects or eiidence of irreversible damage were detected- I 1

by ESP monitoring. Therefore, no analysis or planned course of action to  ;

alleviate problems was necessary. ,

Preoperational Study The Preoperational ESP was initiated in July 1978. It was continued- a

' until.GGNS received its Low-Power Operating License for Unit 1 on June 16, 1982. The background data gathered'during the Preoperational Program was included in'the 1982 Annual Radiological Environmental Operating Report.

1982 Annual Radiological Environmental' Operating Report (AREOR)'

During 1982 Unit 1 did. not enter a power ascension mooc. -

Therefore, the results of the Operational Environmental Surveillance Program 7:ve.

June 16, 1982 to December 31, 1982 are actually an extension of the preoperational program data. The data was presented in Tables 8'through 12 of the 1982 ARE0R. l l

'l had no effect on the radiation levels in the environs surrounding the l l

site. The radiation levels detected by the ESP were within the ranges of i previous years.

1984 AREOR A comparison of the 1984 ESP results with those of previous years I showed no changes. The 1984 radiation monitoring levels did not exceed i the background levels obtained in the Preoperational Program. No harmful  ;

effects or evidence of irreversible damage were detected by 1984 ESP monitoring activities.

4 GGNS Technical Specifications were revised on August 29, 1984, to more accurately reflect the as-built plant and to provide greater.

agreement with standard nuclear power plant technical specifications. The ,

revisions which affected the ESP are summarized below: I o Required air sampling locations are now based on particulate deposition rates instead of atmospheric dispersion rates. This  !

added locations AS-6 and -8 and deleted AS-4 and -9 from the 5 I locations required by technical specifications.

o Fish sampling requirements have been broadened to include any  ;

available commercial or recreational species. )

o An additional vegetation _ sampling site is now required in .

meteorological sector R. j o Iodine analysis of vegetation samples is now required.

o Land use census requirements were expanded to include determination of the nearest resident, milk animal and garden in each of the 16 meteorological sectors instead of just the nearest resident, garden and milk animal locations. j o TLD placement is no longer required in meteorological sectors which are inaccessible.

Full implementation of the revised GGNS Technical Specifications requirements began in September 1984.

1985 ARE0R Operational testing of GGNS was completed during the first naif of 1985. Commercial operation of GGNS began on July 1, 1985. This was the first year that GGNS had substantial operational activity.

F. radiological environmental sample results for 1985 were carefully reviewed by ESP personnel for significant changes. Slight increases above background levels were noted in sediment sample results from the GGNS barge slip. Other sample results were essentially the same as preoperational levels. Based on the review of 1985' sample results, ESP personnel concluded that the operation of GGNS had no adverse radiological impact on the surrounding environment.

J22ARE0R88082601 - I-2

1986 ARE0R' The first full year of commercial operation of GGNS occurred in 1986.

Normal operating levels were achieved and two maintenance outages occurred.

The only significant change from previous years in ESP results occurred in May 1986. Due to the Chernobyl Nuclear Power Plant accident, slight increases above background levels for Iodine-131 and Cesium-137-

]

i were detected in air, milk, vegetation and cistern water samples. Similar i l

increases were also observed by nuclear power facilities in some neighboring states and the Mississippi Division of Radiological Health.

Environmental Surveillance Program personnel assessed 1986 monitoring results by comparing them to preoperational studies and previous 1

environmental surveillance reports. Excluding the May 1986 results attributable to the Chernobyl incident, ESP results for 1986 were in the l range of previous years. No significant trends or abnormalities, harmful effects nor evidence of irreversible damage due to station effluents were detected by the monitoring program. Monitoring program results for 1986 .

confirmed that station effluent controls and equipment are performing  ;-

satisfactorily.

1987 AREOR No significant abnormalities, trends, harmful effects or irreversible 4

damage due to GGNS effluents were observed in ESP data in 1987.  !

Radiological environmental sample analysis results remained at or near background levels as in previous years. Such results confirm that GGNS effluent controls and equipment are performing satisfactorily.

4 1988 ARE0R A comparison of 1988 ESP results'with those of previous years showed no changes. A few of the media, such as sediment and discharge surface water, contained very small amounts of. radioactivity attributable to the operation of GGNS. However, no release limit or reporting' level was j i

exceeded.

No significant abnormalities, trends, harmful effects or irreversible f.I damage due to GGNS effluents were observed in ESP data in 1988. Results l

1.0 INTRODUCTION

I The following is the 1988 Environmental Sampling and Analytical

]

Report for the Environmental Surveillance Program conducted at Grand Gulf Nuclear Station (GGNS), Port Gibson, Mississippi.

Results of completed analyses performed from January through December 1988 are presented in the attached tables.

This report presents data obtained by Arkansas Power and Light (AP&L), Technical Analysis Section and Teledyne Isotopes' Midwest Laboratory on samples collected from January through December 1988. Data on all ,amples, with the exception of thermoluminescent dosimeters (TLDs), was provided by AP&L in 1 monthly progress reports. Teledyne Isotopes provided TLD data  !

in quarterly reports. 4 Data preceded by the symbol "<" were below the instrument's detection capabilities and was reported as the LLD for that i sample media. The LLD was calculated to a 4.66 sigma level I and may vary for each radionuclides, media or counting time. ]

l Data presented in this report is reasonably comparable to that j j encountered in previous years and is indicative of what is i

expected in environmental media of this type. A few of the media, such as sediment and discharge basin surface water, contained very slight amounts of radioactivity attributable to the operation of GGNS. However, no release limit or reporting level was exceeded.

DEVIATION FROM SCHEDULED SAMPLING AND CORRECTIVE ACTION TAKEN All samples were collected within the scheduled period unless noted otherwise in the List of Missing Samples.
