GRAND GULF NUCLEAR STATION 1994 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT

)

h k

Summary The Annual Radiological Environmental Operating Report (AREOR) presents Grand Gulf Nuclear Station (GGNS) Environmental Surveillance Program (ESP) data obtained through analyses of environmental samples collected for the period January 1,1994 through December 31,1994. The AREOR fulfills the requirements of GGNS Technical Specifications 5.6.2.

During 1994 and as in previous years, GGNS detected radionuclides attributable to plant operations in the discharge basin surface water (Tritium) and barge slip sediment (Manganese-54, Cobalt-60 and Cesium-137).

GGNS personnel routinely monitor results from these areas to note any trer.ds.

Their 1994 review of these areas over previous years indicates the following:

Tritium levels are increasing in the discharge basin surface water due to boron leakage from defective control rods in the reactor vessel. This boron leakage interacts with neutrons and produces several byproducts, including tritium. Since 1991, GGNS has noted a steady increase in boron and tritium levels in the reactor water, as a result of these defected blades. However, the present release of tritium is still below all preset limits including the technical specification reporting level for drinking water. GGNS has a program in place to replace control rod blades during refueling outages that have reached the end of their burnup cycle. This effort should reduce the tritium levels in the reactor vessel and subsequently the discharge basin surface water.

Radionuclides in the barge slip sediment appear to be stabilizing as compared to previous years.

Section 2 0 of this report provides a discussion of these results.

Environmental Surveillance Program GGNS established the ESP in 1978 before the station became operational I

(1985) to provide data on background radiation and radioactivity normally present in the area. GGNS has continued to monitor the environment by sampling air, l

milk, water, vegetation, sediment and fish, as well as measuring radiation directly.

The ESP includes sampling indicator and control locations within an i

18-mile radius of the plant. The ESP utilizes indicator locations near the site I

to show any increases or buildup of radioactivity that might occur due to station operation, and control locations farther away from the site to indicate the presence of only naturally occurring radioactivity. GGNS personnel compare indicator results with control and preoperational results to assess any impact GGNS operation might have had on the surrounding environment.

In 1994, GGNS personnel collected 1,336 environmental samples and had them analyzed for radioactivity. They compared results ofindicator locations with control locations and previous studies, and concluded that overall no significant relationship exists between GGNS operation and effect on the plant environs. Their review of 1994 data, in many cases, showed undetectable i

radiation levels in the environment and near background levels in significant pathways associated with GGNS, with exception of the tritium levels detected in the discharge basin surface water. Therefore, they concluded that GGNS operation has had no harmful effects or irreversible damage to the environment.

Attachments Attachment I contains results of air, milk, water, vegetation, sediment and fish samples collected in 1994 and analyzed by Entergy Senices, Inc., (ESI)

1.1 Ep_diation Natural radiation affects all people. Natural radiation exposure comes from the sun, naturally occurring radioactive materials present in the earth, dwelling structures, food and water, air and our bodies. Levels of natural or background radiation vary greatly from location to location.

For example, the average United States resident receives approximately 300 millirem in a year from natural background as shown in Table 1-1.

Man-made sources, including X-rays, radiation medical treatment, fallout from nuclear explosives testing, and racioactive materials from nuclear power plants, contribute additional exposure. However, Table 1-1 i

shows that an individual receives the major portion of dose from natural background and other sources, with nuclear power plants contributing

< l.0 millirem.

1.2 Benefits of Radiation Uranium used in nuclear power plays an important part in meeting today's electricity needs, and it will continue to serve as an important source of energy well into the future. Also, other uses for radiation have benefited our everyday lives during the past 20 or 30 years. Industries use radioisotopes and controlled radiation to sterilize medical supplies, to improve food preservation, in industrial processes, in medical science, and in the study of environmental pollution, agriculture and hydrology. The public receives its main exposure to man-made radiation from medical diagnosis and treatment sources, but the benefit in terms of human lives and health is enormous.

1-1 l

1.3 Safety of Radiation Radiation and the safety of radiation command considerable public attention. Although it is not generally realized, safety regulations fc radioactive materials are much stricter than for other potentially dangerous substances. For example, a person living near a 1000 megawatt electrical (MWe) coal fired plant could receive 7.2 millirem in a year from the naturally occurring radioactive materials contained in the coal that is burnt.

A person living adjacent to a similar sized nuclear plant could expect to receive < l.0 millirem in a year.

In addition, radioactive elements lose their radioactivity, and resulting toxicity with time. Potentially toxic non-radioactive materials, such as lead, silver and mercury, can remain to be a problem until properly treated and stabilized. Table 1-1 presents illustrations of relative radiation exposure risks as compared to other health risks.

1.4 Environmental Surveillance Program Purpose and Desien Criteria GGNS established the ESP to minimize any associated radiation endangerment to human health or the environment by ensuring that plant operating controls function properly. The ESP purpose involves:

Evaluating environmental sampling procedures, equipment and techniques Measuring radiation levels and their variations in environmental e

media in the area surrounding the plant Determining average levels of radiation and radioactive material e

in various environmental media Detecting effects, if any, of GGNS operation on the environmental e

radiation levels and concentrations.

1-2

The ESP design psteda includes:

Analyzing important pathways for anticipated types and quantities of radionuclides released into the environment Considering the possibility of a buildup oflong-lived radionuclides e

in the environment and identifying physical and biological accumulations that may contribute to human exposures Considering the potential radiation exposure to plant and animal life in the environment surrounding GGNS Correlating levels of radiation and radioactivity in the environment e

with radioactive releases from station operation.

1.5 Dose Pathways Associated with GGNS Figure 1-1 shows potential exposure pathways that could occur as a result of a nuclear po wer plant. However, direct dose from gaseous effluent and thyroid dose from ingesting milk involves the most significant environmental dose pathways from a nuclear power station. GGNS operations have little, if any, impact on these pathways due to very low levels of radiation released, remote location and absence of milking animals within five miles of GGNS. In addition, the GGNS Final Environmental Repon lists the first use of drinking water from the Mississippi River as more than 200 miles downstream. Therefore, GGNS operations have little, if any, impact on this pathway.

1.6 Pathways Monitored The ESP includes the r,ampling program for monitoring airborne, waterborne, ingestion and direct radiation pathways as required by Table 6.12.1-1 in the Offsite Dose Calculation Manual (ODCM). GGNS supplements this program with additional sampling in order to provide j

a comprehensive and well-balanced program. Tables 1-2 through 1-5 1-3 l

J

l i

provide a description of the GGNS ESP sample locations. Only sample locations required by the ODCM are keyed to Figures 1-2 and 1-3 as shown in the Tables.

1.7 Previous Data Comparison GGNS personnel observed only one significant change between i

l 1994 results and those from previous years. Tritium levels in the discharge basin continued to increase due to defective control blades which are releasing boron into the reactor water, thereby producing tritium. All other REMP results remained at levels similar to those of previous years. Such results confirm proper functioning of GGNS cffluent controls and equipment.

2.1.1 Interpretations and Trends of Results Air particulate and Iodine-131 results for 1994 compare similarly to those obtained in previous years of the operational and preoperational ESP. Iodine-131 remained undetectable with gross beta concentrations 3

for indicator locations ranging from 0.004 - 0.036 pCi/m with a mean 3

of 0.016 pCi/m as compared to controllocations which ranged from 3

3 0.004 - 0.037 pCi/m with a mean of 0.016 pCi/m. These results indicate the airborne exposure pathway has not been affected by the operation of GGNS and that airborne concentrations continue to be at background levels.

Gross beta concentrations shown in Figure 2-1 further emphasize I

that GGNS has had no influence on ambient radiation levels. This figure shows 1994 monthly average results compared to preoperational results, and 1987 through 1994 yearly average results for indicator locations compared to controls. Values compare similarly over the period.

2.1.2 Program Description The GGNS ESP utilizes nine continuous air samplers to provide i

gross beta, gamma and radiciodine activity measurements by the airborne exposure pathway. These air samplers range in distances from 0.3 to 18 miles (Figures 1-2 and 1-3, and Table 1-2). Five air samplers met the requirements of ODCM Specification 6.12.1, located as follows:

Three near the SITE BOUNDARY in areas of the highest calculated annual average groundlevel D/Q values One in a community that has the highest calculated annual average groundlevel D/Q value (Port Gibson)

One in a control location (Vicksburg, MS).

2-2 l

I GGNS personnel located the remaining four air samplers in areas which provide supplemental data for the ESP.

GGNS personnel placed air samplers 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 charcoal cartridge located directly downstream. GGNS personnel maintained air flow at 1.25 cubic feet per

^

minute. They changed filters and cartridges weekly and had them analyzed for gross beta radionuclides and radioiodine activity, respectively. The analytical contractor analyzed quarterly composites of air filters for gamma radionuclides.

2.2.1 Internretations and Trends of Results i

Gamma radiation dose in 1994 compared similarly to that obtained in previous years as illustrated in Table 2-1. This indicates that the ambient i

radiation levels remained at or near background and have been uninfluenced by the operation of GGNS.

i Figure 2-2, which further represents this conclusion, shows 1994 quarterly average results compared to 1979-1984 preoperational data, and 1987 - 1994 annual average results for indicator locations compared to the Vicksburg control. This figure indicates that ambient radiation levels have t

remained at or near background levels.

As in previous years, GGNS personnel performed an independent verification of the accuracy of GGNS TLD results through the use of NRC TLDs. Figure 2-3 presents these results through the third quaner of 1994. The ESP collects consistent, valid data based on the similarity of TLD results.

2.2.2 Pronram Descrintion The ESP measures ambient radiation in the emrironment surrounding GGNS with 59 TLDs to provide a quantitative measurement'of the area radiation levels. GGNS personnel placed these emrironmental TLDs at distances from 0 to 18 miles (Figures 1-2 and 1-3, and Table 1-3). They collected dosimeters quarterly.

The ESP used the following criteria in establishing TLD locations:

ODCM Specification 6.12.1 requires 40 TLDs, positioned as outlined below:

2.3 MILK Note: A nalytical results presented in Table 6.1 ofAttachment I and summari:. edin Section 4.0.

2-11

.2.3.1 Interpretations and Trends of Results GGNS personnel did not collect milk samples within five miles of the

~ '

GGNS site in 1994 due to the absence of milking animals. However, they did collect milk samples from the Alcorn State University control location and had 4

them analyzed for Iodine-131 and gamma radionuclides. As in preoperational and previous operational years, GGNS has not detected any radionuclides attributable to plant operations.

The ingestion pathway shown in ODCM Specification Table 6.12.1-1 specifies the frequency and location for obtaining milk samples. In addition, Table 6.12.1-1 provides for the use of a food product pathway as an

. alternative in instances of unavailable milk sampling locations. The ESP utilized this alternative in 1994.

2.3.2 Program Description ODCM Specifications require sample collection from milking animals in three locations within a five km distance having the highest dose potential.

If unavailable, ODCM Specifications require one sample from milking animals in each of three areas, between five to eight km, where calculated doses i

exceed 1.0 millirem per year. ODCM Specifications also require one control sample at a distance of 15-30 km.

GGNS personnel collect a control milk sample semiannually from the Alcorn State University Dairy (Figure 1-3 and Table 1-4) to establish background data. However, the ESP did not include milk animals in 1994 within eight km (five miles) of GGNS due to unavailability. Therefore, Section 2.5, Vegetation, addresses the unavailability of milk samples within the vicinity of GGNS.

i 2.4.1 Interpretations and Trends of Results Cistern Water GGNS personnel collected cistern water samples and had them l

l analyzed for gross beta radionuclides, Iodine-131, tritium and gamma radionuclides. Iodine-131, tritium and gamma radionuclides during 1994, and as in preoperational and previous operational years, remained at or near background levels. Gross beta concentrations for indicator locations ranged

(

i from 1.5 - 4.9 pCi/l with a mean of 3.2 pCi/l as compared to the control which ranged from 1.5 - 6.5 pCi/i with a mean of 3.5 pCi/l. In addition, the 1994 gross beta indicator mean is below the average preoperational mean of 4.4 pCi/1. Overall, concentrations continue to remain at background levels.

Surface Water GGNS personnel collected surface water samples and had them analyzed for tritium and gamma radionuclides. As in preoperntional and previous operational years, gamma radionuclide concentrations remained at background levels. In addition, tritium activity at the upstream and downstream Mississippi River locations continue to remain at background levels.

Tritium levels for discharge basin surface water ranged from 6770.0 -

14100.0 pCi/l with a mean of 10115.0 pCi/1. Boron leakage from control rod blades in 1994 and in previous years have contributed to these levels.

The leaking boron interacts with neutrons inside the reactor vessel to produce several by-products, including tritium. GGNS has a program in place to replace control rod blades during refueling outages that have completed their g

burnup cycle. This effort should reduce tritium levels in the reactor vessel and a

subsequently the discharge basin surface water. Figure 2-4, presents tritium l

results from 1985 through 1994 for this area.

t GGNS personnel continue to closely monitor this area, even though levels j

continue to be below all preset limits, including the ODCM Specification drinking water reporting limit.

Groundwater GGNS personnel collected groundwater samples quarterly and had them analyzed for gamma radionuclides and tritium. As in preoperational and previous operational years, concentrations remained at background levels.

i 2.4.2 Program Description ODCM Specifications require water sample collection in the vicinity of GGNS for the measurement of radioactivity by the waterborne exposure pathway.

GGNS personnel sampled cistern water monthly at two locations, I

an indicator near the site (McGee) and a control (Willis) (Figures 1-2 and i

1-3, and Table 1-4). They collected samples in labeled containers and had f

them analyzed for gross beta radionuclides, Iodine-131, gamma radionuclides j

and a quarterly composite tritium.

i i

GGNS personnel sampled surface water from the Mississippi River monthly at points upstream (control) and downstream (indicator) of the plant discharge (Figure 1-2 and Table 1-4). They collected samples in labeled containers and had them analyzed for gamma radionuclides and a quarterly composite tritium.

GGNS personnel took an additional surface water sample from the GGNS Discharge Basin. They composited this sample monthly with an automatic sampler that collected a preset volume at hourly intervals. They collected the sample in a labeled container and had it analyzed for gamma radionuclides and a quarterly composite tritium.

2.5.1 Interoretations and Trends of Results GGNS personnel collected vegetation samples and had them analyzed for gamma radionuclides and Iodine-131. As in preoperational and previous operational years, GGNS did not detect any plant-related radionuclides dunng 1994.

l 2.5.2 Program Description GGNS personnel collected broadleafvegetation samples monthly for measurement of radioactivity by the ingestion exposure pathway, due l

to the unavailability of milk samples within five miles of GGNS, ODCM

[

Specifications require samples of three different kinds of broadleaf vegetation I

grown nearest each of two different offsite locations with highest anticipated annual average groundlevel D/Q.

I GGNS personnel met vegetation sampling requirements by maintaining two gardens inside the SITE BOUNDARY, Sectors J and R. These sampling locations (Figure 1-2 and Table 1-5) provided a more conservative assessment

{

of doses due to the higher deposition rates (D/Qs) than would be measured at offsite sampling locations.

ODCM Specifications also require control samples of each of the j

similar types of onsite vegetation 15-30 km from the site. To fulfill this requirement, the ESP established a control vegetation sample location in Sector K at Alcorn State University (Figure 1-3 and Table 1-5).

The ESP prefers green-leafy vegetables suitable for human f

consumption as the primary source of broadleaf vegetation. At times, GGNS personnel took samples of any vegetation with relatively broad leaves on which airborne radioactive particulate material might be deposited, due to unavailability of green-leafy vegetables suitable for human consumption. They had the raw samples analyzed for gamma radionuclides and lodine-131.

2.6.1 Internretations and Trends of Results GGNS personnel collected sediment samples and had them analyzed for gamma radionuclides. Even though GGNS detected Cesium-137 during the preoperational years at a concentration of 200.0 pCi/kg and over previous operational years which averaged 77.7 pCi/kg, gamma radionuclides remained undetectable at the upstream location. In 1994, the downstream location (Hamilton Lake) contained a Cesium-137 average concentration of 62.5 i

t pCi/kg, as compared to the preoperational average of 295.0 pCi/kg and operational average of 85.1 pCi/kg. Therefore, levels at the upstream and downstream locations continue to remain similar to those of previous years.

Table 2-2 provides an analytical results summary for 1987 through 1994 barge slip sediment samples. GGNS personnel attributes the presence of this radioactivity to buildup of very small amounts of particulates since 1985. This table shows a decrease in activity during 1994, and indicates that radionuclide concentrations in the barge slip sediment appear to be e

stabilizing. Although, previous sampling of the barge slip sediment revealed a wide range of activity, GGNS personnel have found no definite correlation between radionuclide concentrations and plant operating levels, effluent releases or river elevation.

2.6.2 Program Descrintion GGNS personnel collected' sediment samples semiannually at the i

following locations (Figure 1-2 and Table 1-5):

River shoreline in plant efiluent discharge (Barge Slip) f Downstream of the barge slip in the vicinity of the Hamilton Lake outfall(indicator location)

2-21 i

f l

ODCM Specifications require only a sediment sample from the i

downstream location (indicator). However, the ESP utilized additional i

samples from an upstream location (control) and the barge slip (indicator).

GGNS personnel collected sediment samples near the shoreline i

from the top one-inch layer of sediment. They then discarded foreign objects and transferred the samples to clean, labeled containers for gamma radionuclide analyses.

Downstream of the GGNS discharge point into the Mississippi River (indicator location)

Upstream of the GGNS discharge point into the Mississippi River uninfluenced by plant operations (control location).

GGNS personnel collected fish by net, trotline, electroshock or purchased from commercial fishermen. They accompanied commercial fishermen, when purchasing samples, to ensure representative and valid samples from required locations.

GGNS personnel collected a suflicient amount from each location to provide a minimum of 1000 grams (wet weight) of eviscerated fish sample. They had the samples analyzed for gamma radionuclides.

2.8.1 Interpretations and Trends of Results In 1994, GGNS personnel collected seven special samples and had them analyzed for gamma radionuclides. Discussion below provides descriptions of special samples collected and their results.

Surface Wats - One sample from Outfall 010 - Plant-related radionuclides not detected.

Sediment - Six samples collected as follows:

- One influent sample from Basins A and B - Plant-related radionuclides not detected.

- One effluent sample from Basins A and B - Plant-related radionuclides not detected.

- One sample from Manhole #3 - Plant-related radionuclides not detected.

- One sample from Stream B - Cesium-137 detected at a concentration of 26.0 pCi/kg.

2.8.2 Proeram Description GGNS personnel collected special samples occasionally from nonroutine ESP locations to provide supplementary data and to address areas of special interests. Sample media may include sediment, water, milk, fish, meat and vegetation and may be analyzed for gamma radionuclides, Iodine-131, tritium or gross beta radionuclides, depending upon current interest.

2.9 ANNUAL LAND USE CENSUS 2-28

2.9.1 Interpretations and Trends of Results l

GGNS did not modify the ESP, even though some minor changes occurred from 1993 to 1994, as shown in Table 2-3. ' Also, the land use census identified no location which would yield a calculated dose or dose commitment greater than those currently being calculated.

The 1994 land use census results indicated land uses in the zero to 5-mile area surrounding GGNS have remained basically the same as those reported in the 1992 and 1993 annualland use census. Table 2-4 presents the 1994 land use census data sheets.

2.9.2 Pronram Description GGNS personnel conducted an annual land use census as required l

by ODCM Specification 6.12.2. This census identifies changes in uses ofland in unrestricted areas surrounding GGNS which would require modifications to the ESP or ODCM. The land use census identified important criteria in each I'

of the 16 meteorological sectors, such as nearest:

Residence Animal milked for human consumption Garden of greater than 50 m (500 ft2) producing broadleaf vegetation.

2 GGNS personnel conducted the 1994 land use census by:

Five mile field survey confirmation in each sector to locate:

Nearest permanent residence i

Nearest unoccupied residence Nearest garden and approximate size Nearest milking animal.

SECTION 3.0 ANALYTICAL PROGRAM TECHNICAL DESCRIPTION 3-i

y i

3.1 Samnie Handline and Treatment The laboratory stafTtreats and stores samples upon receipt. Environmental

[

samples frequently require treatment prior to analysis, depending on media and l

analyses type.

3.1.1 Water Samnies Generally, field personnel acidify one-gallon water samples with f

five milliliters (ml) of concentrated hydrochloric acid when collected, unless otherwise directed by the analyticallaboratory. Tritium samples for analyses are not usually stored in polyethylene bottles for more than three or four months because water can evaporate through polyethylene.

3.1.2 Air Filters The laboratory handled air filters with care during heavy dust loadings to avoid removing any particulate matter. They normally received air filters in plastic containers; the container as well as sample required analysis for some extremely low-level analyses.

3.1.3 Milk The laboratory usually refrigerated milk samples until analyzed.

They added a preservative (formaldehyde), if analyses delayed for more than a few days, to inhibit bacterial growth and retard spoilage. Unless shipped on ice, milk samples analyzed for Iodine-131 require addition of 100 ml formaldehyde, of which field personnel normally add 40 ml prior to shipment, to avoid binding of the iodine that may occur with smaller levels of formaldehyde.

l 3.1.4 Soil and Bottom Sediment The laboratory dried, pulverized and sieved soil and sediment samples before analysis. They then mixed the samples to ensure a homogeneous mixture.

3-1 l

i 3.1.5 Other Samples t

The laboratory preserved perishable samples by refrigeration or

[

freezing. Vegetation and other samples may require drying, pulverizing or ashing before or after analysis for long-term storage.

3.2 Gross Beta Air Sample Analysis The laboratory counted air filters for 100 minutes, or until required LLDs

[

shown in ODCM Specification Table 6.12.1-3 were achieved, 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 to allow for decay of short-lived materials such as radon and thoron.

i 3.3 Gross Beta Water Sample Analysis i

This process is used to measure overall beta radionuclides of water samples without identifying specific radioactive isotope present. This analysis involves evaporating a two hundred mi sample in a beaker and then drying beaker residue in a 2-inch stainless steel planchet at 100 C.

The laboratory counted the planchets for 100 minutes, or until required LLDs

[

shown in GGNS ODCM Specification Table 6.12.1-3 were achieved, in a low-background alpha-beta counting system. Activity calculation includes a self-absorption correction factor for counter efficiency based on weight of residue on each planchet.

3.4 Tritium Water Sampic Analysis The laboratory added five ml of water to 15 ml ofliquid scintillation solution in a 25 ml vial and then inserted the vial into a liquid scintillation spectrometer for a i

300-500 minute count, or until required LLDs shown in GGNS ODCM Specification j

Table 6.12.1-3 were achieved.

l 3.5 lodine-131 Sample Analysis The laboratory mixed up four liters or more of the sample with a stable iodine carrier solution and passed the sample through an anion exchange resin column to remove iodine from the sample.

]

l 3-2 i

r

. = -.

J Next, they strip the iodine from the resin with a sodium hypochlorite solution, reduce with hydroxylamine hydrochloride and extract into carbon tetrachloride as free iodine. They then back-extract the free iodine into sodium bisulfite solution and precipitate as silver iodide. The laboratory mounted the precipitate on a stainless steel planchet and counted for 240 minutes, or until required LLDs shown in ODCM Specification Table 6.12.1-3 were achieved, in a low-background alpha-beta counting i

system.

3.6 Gamma Isotopic Samole Analysis 3.6.1 Milk and Water The laboratory fills a 3.5-liter Marinelli beaker with a representative aliquot of the sample and counts for a minimum of 240 minutes, or until required LLDs shown in GGNS ODCM Specification Table 6.12.1-3 were achieved, in a shielded Germanium-Lithium (GeLi) detector coupled to a computer-based data acquisition system which performed a pulse height analysis.

A computer software program defines peaks by certain changes in f

slope of the spectrum. The program also compares energy of each peak with a library of peaks for radionuclide identification and then performs calculation using appropriate fractional gamma ray abundance, halflife, detector efliciency and net counts in the peak region.

3.6.2 Venetation. Food and Garden Crops, and Fish The laboratory loads a maximum quantity of undried vegetation, food or garden crop sample into a tared 3.5-liter Marinelli beaker and weighs. They then count the sample for 60 minutes, or until required LLDs shown in GGNS ODCM Specification Table 6.12.1-3 were achieved, in a shielded GeLi detector as described in Section 3.6.1.

3-3

The laboratory loads as much as possible (up to the total sample) of the edible portion of a fish into a tared Marinelli beaker and weighs.

They diluted the sample with deionized water to weigh 3.5 kg and then count for a minimum of 240 minutes in a shielded GeLi detector as described in Section 3.6.1.

r 3.6.3 Soils and Sediments The laboratory dries soils and sediments at a low temperature (less than 100 C), loads into a tared 1.0-liter Marinelli beaker and weighs.

They then count the sample for 240 minutes, or until required LLDs shown in GGNS ODCM Specification Table 6.12.1-3 were achieved, in a shielded E

GeLi detector as described in Section 3.6.1.

3.6.4 Charcoal Capridnes The laboratory counts charcoal cartridges in a Marinelli beaker, with orie to four cartridges positioned on the face of a GeLi detector and up to seven cartridges on its side. They calibrate each detector for both top and side positions and determine counting efficiency. They determine the Iodine-131 f

detection limit for each charcoal cartridge, assuming no positive results for Iodine-131, by utilizing smallest volume of air recorded for a cartridge within the Marinelli beaker. The laboratory counts each charcoal separately, if lodine-131 observed in the screening count, by positioning on face of the detector.

3.6.5 Air Particulate The laboratory stacks 12 to 14 (depending on calendar quarter) air particulate filters for a quarterly composite for each field station one on top of a other. They then count the samples for at least one hour, or until regt. ' d LLDs shown in GGNS ODCM Specification Table 6.12.1-3 were achieved, in a shielded GeLi detector as described in Section 3.6.1.

3-4 l

~

3,7 Thermoluminescent Dosimetry The GGNS ESP uses TLDs manufactured by Panasonic (Model UD-814).

Although, these TLDs contain one lithium borate and three calcium sulfate phospor elements, only the calcium sulfate phospor element results are used for reponing purposes.

The laboratory anneals the TLDs prior to shipment. Upon arrival at GGNS, personnel sort and place designated TLDs in a plastic bag (two TLDs/ bag) prior to i

placing in field. The laboratory reads the TLDs, upon return from the field, in a Panasonic Model UD-710 TLD reader.

3.8 Data Reportine Conventions The laboratory calculated mean of analytical results as follows:

2 = Xi / n where:

X = Mean Xi = Individual sample results n = Number of sample results They rounded calculated values by inspection of digits to the right oflast reported digit, with values less than 5 rounded down and values greater than 5 rounded up. They rounded a reported value to an even number, when value equaled 5.

The laboratory reported analytical results less than the 2 sigma counting.

error as less than LLD calculated for that sample. They reponed analytical results -

greater than the sigma counting error along with associated 2 sigma counting error as a plus or minus (1) term.

The laboratory considers calendar quarters as the following time periods:

1st Quarter January - March

=

2nd Quarter April - June

=

3rd Quaner july - September

=

4th Quarter October - December

SECTION 6.0 1994 SAMPLING AND ANALYTICAL RESULTS 6-i

r

.f 6.1 1994 Data Attachments I and II present data obtained by ESI System Chemisty and Waterford-3 Dosimetry Section on samples collected from January through t

December 1994. ESI System Chemistry provides data in monthly progress reports. Waterford-3 Dosimetry Section provides TLD data in quarterly reports.

L With exception of the increase in tritium levels in the discharge basin surface water, data presented in Attachments I and II compare to that encountered in preoperational and previous operational years.

6.2 Lower Limit of Detection ESI System Chemistry routinely counts lower than the maximum LLD required by ODCM Specification Table 6.12.1-3. Factors such as unavoidable small sample size, background fluctuations, presence ofinterfering radionuclides or other uncontrollable circumstances cause ODCM Specifications' LLDs to be unachievable in some instances. However, GGNS personnel's review of 1994 results indicates acceptable LLDs within required ODCM Specification limits.

6.3 Reportine I,evels GGNS' review indicates that no samples equaled or exceeded reporting levels for radioactivity concentration in environmental samples, as outlined in ODCM Specifications Table 6.12.1-2 when averaged over any calendar quarter, l

due to GGNS eflluents. Therefore,1994 results did not trigger any Radiological Monitoring Program Special Reports.

6.4 Sampline Deviations The ESP missed one air sample required by ODCM Specifications at air sampling station AS-1 PG during the sampling period of November 29,1994 through December 6,1994 due to personnel error. This error occurred as a result of adding oil to the sampler during change out and not returning the unit 6-1

back to service. GGNS personnel were retrained on the sampling procedure and this incident did not recur.

The ESP lost six TLDs required by ODCM Specifications during 1994, due to vandalism or flooding from the Mississippi River. Other TLD programs experience losses of this type. In 1994, GGNS personnel calculated a 96%

(154 of 160) recovery rate for required ODCM Specification TLDs, which compares with other TLD programs. In addition, GGNS personnel were unable to obtain data from three TLDs required by ODCM Specifications during the year due to flood waters which either prevented placement or retrieval. Flood waters are seasonal at GGNS and is a typical problem incurred by other TLD programs.

The ESP did not include milk sampling within five miles (8 km) of GGNS in 1994 due to unavailability. Therefore, GGNS personnel continue to sample the Alcorn State University Control location semiannually until such time that milk samples become available within five miles (8 km) of GGNS. They collected vegetation samples to monitor the ingestion pathway, as specified in ODCM Specifications Table 6.12.1-1, because of milk unavailability.

GGNS personnel conducted all other ESP activities required by ODCM Specification without exception.

6.5 Radioactivity Not Attributable To GGNS The GGNS ESP detected radioactivity attributable to other sources twice.

These include the 25th Chinese nuclear test explosion in 1980, and the radioactive plume release due to reactor core degradation at Chernobyl Nuclear Power Plant in 1986.

l 6.6 Sampline Relocation

(

Vegetation and milk sampling locations did not change in 1994. Therefore, i

l GGNS personnel did not identify any new locations or report circumstances of unavailability in the Semiannual Radioactive Efiluent Release Report.

}

6.7 Comparison To Federal and State Programs GGNS personnel compared GGNS data to federal and state monitoring programs as results became available. The programs used for comparison include the U.S. Nuclear Regulatory Commission (NRC) TLD Direct Radiation Monitoring Network and the Mississippi State Department of Health (MSDrl),

Division of Radiological Health.

l The latest available NRC TLD Network results compare to those from the GGNS ESP. In addition, as shown in Section 2.2 of this report, GGNS and NRC TLDs produced similar results on the average.

The MSDH and the GGNS ESP entail similar radiological monitoring sampling requirements. These programs include collocated air samples and j

splitting or sharing sample media such as vegetation, water, sediment, meat, fish and milk. Both programs have obtained similar results over previous years.

In 1994, and as in previous years, the MSDH and GGNS detected radioactivity attributable to plant efiluent in the barge slip.

6.8 Unavailable Results GGNS received analytical contractor results in adequate time for inclusion in this report. In addition, GGNS' review identified no missing results.

6.9 Ilarmful EITects or Irreversible Damane The ESP monitoring did not detect any harmful effects or evidence of irreversible damage in 1994. Therefore, GGNS personnel addressed no problems.

Summary of Monitorina Results Plant-related isotopes were detected in the discharge surface water and sediment during this reporting period.

The term "GG" ending of a lab number denotes a duplicate sample.

Missed Samples No sample at location AS-5 for the period of 4/12/94 - 4/19/94 due to insufficient flow caused by blown fuse.

No samples were collected at location AS-10 for the period of 4/26/94 - 5/20/94 due to high flood waters.

No sample was collected at location AS-1 for the period of 11/29/94 - 12/6/94 due to the sampler inadvertently not being returned to service.
