1996 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT
)
)
u
Summary i
l The Annual Radiological Environmental Operating Report (AREOR) presents Grand Gulf Nuclear Station (GGNS) Environmental Surveillance Progrr.m (ESP) data obtained through analyses of environmental samples collected for the period January 1,1996 through December 31,1996. The AREOR fulfills the requirements of GGNS Technical Specifications 5.6.2.
During 1996 and as in previous years, GGNS detected plant-related radionuclides in the discharge basin surface water (Cobalt-60 and Tritium).
GGNS personnel routinely monitor results from these areas to note any trends.
Their 1996 review of these areas over previous years indicates the following:
Cobalt-60 levels in the discharge basin surface water continue to be l
well below the lower limit of detection (LLD) values outlined in the Offsite Dose Calculation Manual (ODCM) Specifications and are not demonstrating any increase.
Tritium levels in the discharge basin surface water continue to be elevated due to increased levels in the reactor coolt.nt and radioactive effluents caused by stress corrosion cracking of control blade absorber tubes. This has resulted in a pathway for the release of l
boron. Subsequently, tritium production results from the neutron activation. Reduction in tritium levels can be expected as control blades are gradually replaced and the number of blades above 20%
depletion is reduced. No regulatory limits for radioactive effluents have been exceeded.
Environmental Surveillance Program GONS established the ESP in 1978 before the station became operational (1985) to provide data on background radiation and radioactivity normally present in the area. GGNS has continued to monitor the environment by sampling air, i
l
J milk, water, vegetation, sediment and fish, as well as measuring radiation directly.
The ESP includes sampling indicator and control locations within an 18-mile radius of the plant. The ESP utilizes indicator locations near the site 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 environme lt.
In 1996, GGNS personnel collected environmental samples for radiological analysis. They compared results ofindicator locations with control locations and previous studies, and concluded that overall no significant 4
relationship exists between GGNS operation and effect on the plant environs.
Their review of 1996 data, in many cases, showed undetectable 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.
i Harmful Effects or Irreversible Damage i
The ESP monitoring did not detect any harmful effects or evidence of irreversible damage in 1996. Therefore, no analysis or planned course of action to alleviate problems was necessary.
Reporting Levels GGNS' review indicates that no samples equaled or exceeded reporting 2
3-levels for radioactivity concentration in environmental samples, as outlined in ODCM Specifications Table 6.12.1-2 when averaged over any calendar quarter,
)
due to GGNS effluents. Therefore,1996 results did not trigger any Radiological Monitoring Program Special Reports.
R_adioactivity 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.
Comparison To Federal and State Programs GGNS personnel compared ESP 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 (MSDH),
Division of Radiological Health.
The latest available NRC TLD Network results compare to those from the GGNS ESP. Through 1996, GGNS and NRC TLD results continue to remain similar to the historical average and continue to verify that plant operations is not affecting the ambient radiation levels in the environment.
The MSDH and the GGNS ESP entail similar radiological enviromnental monitoring program requirements. These programs include collocated air samples and splitting or sharing sample media such as vegetation, water, sediment, fish, and milk. Both programs have obtained similar results over previous years.
In 1996, and as in previous years, the MSDH and GGNS detected radioactivity attributable to plant effluent in the barge slip.
Sampling Deviations The ESP lost two TLDs required by ODCM Specifications during 1996 due to vandalism. Other TLD programs experience losses of this type. In 1996,
d i
GGNS personnel calculated a 99% (142 of 144) recovery rate for required ODCM Specification TLDs, which compares with other TLD programs.
The ESP did not include milk sampling within five miles (8 km) of GGNS in 1996 due to unavailability. Although GGNS personnel were previously i
sampling the Alcorn State University control location, changes were made to the ODCM Technical Specifications which specified that the control would only be collected if an indicator station exists. GGNS personnel did continue to collect vegeiation 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 as required by the ODCM Specification without exception.
Program Modifications GGNS made the following REMP modifications during 1996:
Discontinued air sampling locations AS-5 TC and AS-6 BF.
Discontinued cistern water sampling.
e j
Changed groundwater sampling frequency from quarterly to annually e
j and indicator location from Arnold Acres to GGNS Construction Well.
Discontinued sampling the discharge basin surface water and changed sampling frequency for the upstream and downstream surface wate, t
j locations from monthly to quarterly. In addition, added an a mual sample at a downstream location during a liquid radwaste discharge.
Changed vegetation sampling frequency from three different sample types from two onsite gardens and one control location on a monthly basis to one sample type on a quarterly basis from one of the two onsite gardens and control location.
iv
(
l I
l Changed milk sampling frequency to quarterly for indicator locations, e
l when available, with sampling of the control location only occurring with the presence of indicator locations.
Discontinued fish sampling.
Changed sampling frequency for the downstream sediment location (SEDHAM) from semiannually to annually and added an annual upstream location.
Reduced TLDs from sixteen inner and outer ring TLDs to sixteen inner / outer ring only and eight special interest areas.
Changed land use census frequency from annually to once every two years.
These modification were approved July 1996.
Unavailable Results GGNS received analytical contractor results in adequate time for inclusion in this report. In addition, GGNS' review identified no missing results.

1.1 Environmental Surveillance Program Purpose and Design 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 t:chniques.
i Measuring radiation levels and their variations in environmental e
media in the area surrounding the plant.
Determining average levels of radiation and radioactive material in various environmental media.
Detecting effects, if any, of GGNS operation on the environmental radiation levels and concentrations.
The ESP design criteria includes:
Analyzing important pathways for anticipated types and quantities of radionn,lides released into the environment.
Considering the possibility of a buildup oflong-lived radionuclides in the environment and identifying physical i
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 with radioactive releases from station operation.
1.2 Dose Pathways Associated with GGNS Figure 1-1 shows potential exposure pathways that could occur as a result of a nuclear power plant. liowever, direct dose from gaseous
)
effluent and thyroid dose from ingesting milk involves the most J

l
^
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 Report lists the first use of drinking water from i
the Mississippi River as more than 200 miles downstream. Therefore, GGNS operations have little, if any, impact on this pathway.
1.3 Pathways Monitored The ESP includes the sampling program for monitoring airborne, waterborne, ingestion and direct radiation pathways as required by Table 6.12.1-1 in the ODCM. GGNS supplements this program with additional sampling in order to provide a comprehensive and well-balanced program.
Tables 1-1 through 1-4 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. Section 2.0 of this report provides a discussion of 1996 sampling results and Section 3.0 provides a summary of results for the monitored exposure pathways.
1.4 Program Description 1.4.1 Air Particulate and Radiciodine i
The GGNS ESP utilized five continuous air samplers to provide gross beta, gamma and radiciodine activity measurements by the airborne exposure pathway at the begirming of 1996.
GGNS modifications to the REMP reduced air sampling locations to three. These remaining air samplers (Figures 1-2 and 1-3, and Table 1-1) met the requirements of ODCM Specification 6.12.1, as follows:
1-2
,.e
. -m
i One close to the SITE BOUNDARY having the highest calculated annual average groundlevel D/Q One in the vicinity of a community having the highest calculated annual average groundlevel D/Q (Port Gibson)
)
One from a control location 15 - 30 km (10 - 20 miles) 1 distance (Vicksburg, MSL GGNS personnel placed air samplers one meter above the ground in weatherproof houses, with a 47-millimeter glass fiber filter in the intake line of the vacuum pump and a 2 x l-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 radiciodine activity, respectively. The analytical laboratory analyzed quarterly composites of air filters for gamma
'l radionuclides.
1.4.2 Thermoluminescent Dosimetry 4
The GGNS ESP measured ambient radiation in the environment surrounding GGNS with 59 TLDs to provide a quantitative measurement of the area radiation levels at the beginning of 1996. GGNS modifications to the REMP reduced TLD locations to 40 (Figures 1-2 and 1-3, and Table 1-2).
They collected dosimeters quarterly and used the following l
criteria in establishing TLD locations.
l l
1-3 l'
1 l
ODCM Specification 6.12.1 requires 40 TLDs, j
positioned as outlined below:
Eight TLDs located in the general areas of e
the site boundary.
Eight TLDs located approximately 3 to 5 miles from the site.
4 Eight TLDs located in special interest areas t
such as population centers, nearby residences, schools, and in 1 or 2 areas to serve as control stations.
j Sixteen permanent TLD stations at the protected j
area boundary.
j The remaining 3 TLDs utilized as duplicates at I
varying locations.
1.4.3 Milk At the beginning of 1996, ODCM Specifications required the following:
Sample collection from milking animals in three locations within a five km distance having the highest dose potential.
If milking animals were unavailable within five km, collect i
milk samples from three locations, between five to eight km, where calculated doses exceed 1.0 millirem per year.
One control sample at a distance of 15-30 km.
GGNS modifications to the REMP reduced the milk sampling frequency to quarterly for indicator locations, when i
available, with sampling of the control location only occurring when indicator locations are present.
1-4 I
s 4
=.
GGNS personnel were previously collecting a control milk sample semiannually from the Alcorn State University Dairy (Figure 1-3 and Table 1-3) to establish background data.
J However, the ESP did not include milk animals in 1996 within eight km (five miles) of GGNS due to unavailability.
Therefore, Section 1.4.5 of this report addresses the unavailability of milk samples within the vicinity of GGNS.
1.4.4 Cistein Water. Surface Water and Groundwater GGN personnel sampled cistern water monthly at two locauona, an indicator near the site (McGee) and a control (Willis)(Figures 1-2 and 1-3, and Table 1-3) at the beginning of 1996. GGNS modifications to the REMP eliminated these j
locations after July 1996. They collected samples in labeled containers and had them analyzed for gross beta radionuclides, Iodine-131, gamma radionuclides and a quarterly composite tritium.
j Although sampling frequency was reduced to quarterly after July 1996 due to REMP modifications, GGNS persornel continued to sample surface water from the Mississippi River monthly at points upstream (control) and downstream (indicator) of the plant discharge (Figure 1-2 and Table 1-3) through 1996.
GGNS personnel also collected a annual downstream sample during a liquid radwaste discharge as a result of REMP modifications. They collected samples in labeled containers and had them analyzed for gamma radionuclides and a quarterly composite tritium.
1-5
l 1
Although this location was eliminated aner July 1996 due to REMP modifications, GGNS personnel continued to collect 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 i
composite tritium.
4 GGNS personnel sampled groundwater quarterly from two locations (Figure 1-2 and Table 1-3), Arnold Acres (indicator location) and Port Gibson City (control location) at the beginning 1
of 1996. GGNS modifications to the REMP reduced sampling frequency to annually and relocated the indicator location from Arnold Acres to the onsite GGNS Construction Well after July 1996. They collected samples in labeled containers and had them analyzed for gamma radionuclides and tritium.
1.4.5 Vegetation l
At the beginning of 1996, GGNS personnel collected
)
broadleaf vegetation samples monthly for measurement of radioactivity by the ingestion exposure pathway, due to the unavailability of milk samples within five miles of GGNS i
as follows:
I Three different kinds of broadleaf vegetation grown nearest each of two difTerent offsite locations with highest anticipated annual average groundlevel D/Q.
GGNS met this requirement by maintaining two 1-6 1
l I
)
~
gardens inside the SITE BOUNDARY, Sectors J and H.
These sampling locations (Figure 1-2 and Table 1-4) provided a more conservative assessment of doses due to the higher deposition rates (D/Qs) than would be measured at offsite sampling locations.
Control samples of each of the similar types of onsite vegetation 15-30 km from the site. GGNS met this requirement by maintaining a garden at in Sector K at Alcorn State University (Figure 1-3 and Table 1-4).
GGNS modifications to the REMP reduced sampling frequency from three different sample types from two onsite gardens and one control location on a monthly basis, to one sample type on a quarterly basis from one of tE vo onsite gardens and a control location.
The ESP prefers green-leafy vegetables suitable for human 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 Iodine-131.
1.4.6 Sediment At the beginning of 1996, GGNS personnel collected sediment samples semiannually at the following locations (Figure 1-2 and Table 1-4):
1-7
1 River shoreline in plant effluent discharge (Barge Slip)
Downstream of the barge slip in the vicinity of the Hamilton Lake outfall (indicator location)
Upstream from the GONS discharge (Upper Grand GulfLanding)
ODCM Specifications require only a sediment sample from the downstream location (indicator). However, the ESP utilized additional samples from an upstream location (control) and the barge slip (indicator).
GGNS modifications to the REMP reduced the sampling frequency for the downstream sediment location (SEDHAM) to annually and added an annual upstream location.
GGNS personnel collected sediment samples near the shoreline 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.
1.4.7 Fish At the beginning of 1996, GGNS personnel collected fish semiannually in the Mississippi River at the following locations (Figure 1-2 and Table 1-4):
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 modifications to the REMP eliminated these locations i
after July 1996.
1-8

)
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 sufficient 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.
1.4.8 Special Samples GGNS personnel collected special samples occasionally from noncoutine 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.
1.4.9 Land Use Census GGNS modifications to the REMP reduced the land use census frequency from annually to once every two years. In previous years, GGNS conducted an annual land use census as described in ODCM Specification 6.12.2. This census identifies 6
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 of the 16 meteorological sectors, such as nearest:
Residence.
Animal milked for human consumption.

(INTERPRETATIONS AND TRENDS OF RESULTS)
I k
i 2-i
h 2.1 Air Particulate and Radiciodine Sampic Results GGNS did not detect any gamma radionuclides in the quarterly air particulate composites nor Iodine-131 in the radiciodine canridges during 1996, as has been the case in previous years. The ESP detected
{
radioactivity in this pathway 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 Chemobyl Nuclear Power Plant in 1986. Therefore, the airborne exposure pathway has been unaffected by the operation of GONS and airbome i
concentrations continue to be at background levels.
Gross beta concentrations during 1996 for indicator locations 1
ranged from 0.005 - 0.0473 pCi/m3 with a mean of 0.021 pCi/m3 as compared to the control locations which ranged from 0.00591 - 0.0555 pCi/m3 with a mean of 0.020 pCi/m3. This further emphasizes that the airborne pathway continues to remain at background levels, 2.2 Thermoluminescent Dosimetry Sample Results Gamma radiation dose in 1996 compares to previous years as i
shown in Figure 2-1. This figure shows 1987 - 1996 annual average i
results for indicator locations compared to the Vicksburg control. This i
figure indicates that ambient radiation levels have remained at or near j
background levels.
The ESP recorded the following quarterly TLD doses for ODCM Specification locations during 1996:
Inner ring, mean of 9.5 mrem and range of 4.5 - 14.3 mrem Outer ring, mean of 9.6 mrem and range of 4.8 - 13.9 mrem Special Interest, mean of 9.4 mrem and range of 7.0 - 12.6 mrem Control, mean of 10.7 mrem and range of 8.9 - 13.2 mrem.
l 2-1
i i
GGNS reported measured doses in 1996 as net exposure (field reading -
transit / shield reading) normalized to 92 days Previously, GGNS had i
reported measured doses as gross exposure. T his reporting change did not affeet the program since GGNS relies on comparison of the indicator locations to the control as a measure of plant impact. GGNS' comparison of the inner, outer and special interest TLD results to the control, indicates that the ambient radiation levels are unaffected by plant operations. Therefore, levels continue to remain et or near background.

2.3 Milk Sample Results GGNS personnel did not collect milk samples within f'ive miles of the GGNS site in 1996 due to the absence of milking animals.
However, they did collect milk samples from the Alcorn Stste University control location and had 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.
2.4 Water Sample Results Cistern Water GGNS did not detect any gamma radionuclides, Iodine-131 or tritium in cistern water samples during 1996, which is consistent with previous years. Gross beta concentrations for the indicator location had a mean of 2.09 pCi/l as compared to the control which ranged from 2.58 - 6.47 pCi/l with a mean of 4.03 pCi/1. These results indicate that this pathway has not been affected by plant operations.
Surface Water Gamma radionuclides remained undetectable in the upstream and downstream Mississippi River location which is consistent with preoperational and previous operational years. In addition, gamma radionuclides were undetectable in an annual downstream sample collected during a liquid radwaste discharge. Tritium was detected in small concentrations, well below the required LLD value, at the upstream, downstream and annual downstream location as follows:
Upstream - mean of 153.4 pCi/1, range of 114.0 - 219.0 pCi/l Downstream - mean of 194.0 pCi/l, range of 140.0 - 271.0 pCi/l Annual Downstream - mean of 385.5, range of 359.0 - 412.0 pCi/1.
2-4
)
I These tritium values ranged from 79% to 94% below the required LLD i
I value of 2000 pCi/1, therefore, the uncertainty and error associated with these results are high. Based on this and review of historical data, GGNS concluded that concentrations continue to remain at or near l
background levels at these locations.
Cobalt-60 was detected in the discharge basin at concentrations which ranged from 2.0 - 4.0 pCi/l with a mean of 3.3 pCi/1. These values ranged from 73% to 87% belew the required LLD value of 15.0 pCi/1, therefore, the uncertainty and error associated with these results are high. Based on this and review of historical data, and the fact that this radionuclide was not detected after April 1996, GGNS concluded that there is no detectable trend associated with this area.
Tritium levels for discharge basin surface water ranged from 10835.0 - 16440.0 pCi/l with a mean of 13847.2 pCi/1. Tritium levels continue to be elevated due to increased levels in the reactor coolant and radioactive effluents caused by stress corrosion cracking of control blade tubes. This has resulted in a pathway for the release of boron.
Subsequently, tritium production results from the neutron activation.
Reduction in the tritium levels can be expected as control blades are gradually replaced and the number of blades above 20% depletion is reduced. No, regulatory limits for radioactive effluents have been exceeded. Figure 2-2 presents tritium results from 1985 through 1996 for this area.
Groundwater GGNS did not detect any gam.ma radionuclides or tritium in groundwater samples during 1996, as has been the case in previous years. These results indicate that this pathway has not been affected by plant operations.

1 2.5 Vegetation Sample Results GGNS did not detect any gamma radionuclides in vegetation i
samples during 1996, as has been the case in preoperational and z
previous operational years. These results indicate that this pathway has not been affected by plant operations.
2.6 Sediment Sample Results i
Gamma radionuclides remained undetectable in the upstream Mississippi River location during 1996 which is consistent with previous I
years. The downstream Mississippi River locatior. (llamilton Lake) contained Cesium-137 at concentrations which ranged from 31.2 -
112.0 pCi/kg with a mean of 85.1 pCi/kg. This location also contained Cesium-137 during the preoperational years at an average concentration of 295.0 pCi/kg. GGNS attributes this activity at the downstream location to past atmospheric weapons testing, since the probability of this location being affected by plant operations is remote due to the enormous dilution and sedimentation factors involved with the Mississippi River.
No gamma radionuclides were detected at the barge slip location (SEDBAR) during this reporting period. Table 2-1 provides an analytical results summary for 1987 through 1996 barge slip sediment samples.
GGNS personnel attributes the presence of radioactivity at this area over previous years to buildup of very small amounts of particulates, l
This table continues to show that radionuclide concentrations in the
^
barge slip sediment are 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.

2.7 Fish Sample Results GGNS did not detect any gamma radionuclides in fish samples during 1996, as has been the case in preoperational and previous operational years. These results indicate that this pathway has not been affected by plant operations.
2.8 Special Sample Results in 1996, GGNS personnel collected sixteen special samples and had them analyzed for gamma radionuclides, gross beta radionuclides and/or tritium. Discussion below provides descriptions of special samples collected and their results.
Eight groundwater samples as follows:
Four samples (one recount) from North Construction Well #3 - gross beta radionuclides and tritium detected l
twice/no gamma radionuclides detected.
Four samples (one recount) from South Construction Well #4 - gross beta radionuclides and tritium detected once/no gamma radionuclides detected.
One rainfall sample - no tritium detected.
Two sediment samples as follows:
j One sample from Basin A - Manganese-54 and Cesium-137 detected.
One sample from Basin B - Manganese-54, Cobalt-60 and Cesium-137 detected.
One sewage effluent sample from Outfall 010 - no gamma radionuclides detected / gross beta radionuclides detected.
l' 2-9 1
= _.
~
m 4
Four stormwater samples from Outfall 007 - gross beta radionuclides not detected / tritium detected once.
Detectable measurements from the sampling areas are well below the required environmental LLD values. Therefore, the uncertainty and 4
error associated with these results are high. Results are summarized in Section 3.0.
2.9 Land Use Census Results GGNS did not conduct a land use census during 1996 as a result of the REMP modifications. This modification changed the frequency from annual to once every two years.
2.10 Interlaboratory Comparison Results RBS' environmental laboratory analyzed interlaboratory comparison samples for GGNS. Attachment I contains these results.
GGNS' review of RBS' interlaboratory comparison indicated that 95% of the sample results were within the acceptable control limits of the three normalized deviations, with 5% outside the limits. GGNS' and RBS' review of sample results outside the acceptable control limits indicated that there was no impact on previous reported data. Section 10.0 of Attachment I provides more discussion on sample results outside the acceptable controllimits 2-10

Analytical Laboratory Services Entergy's nuclear sites discontinued utilizing the laboratory services of Entergy Services, Incorporated located in Little Rock, Arkansas, and began using River Bend Station's environmental laboratory located at St. Francisville, Louisiana on May 1,1996.
Program Modifications Modifications to GGNS' Radiological Environmental Monitoring Program were approved during July 1996. These modifications were as follows:
Air sampling locations AS-5 TC and AS-6 BF were discontinued.
Cistern water sampling was discontinued.
Sampling frequency for groundwater was changed from quarterly to annually and indicator location was changed from Arnold Acres to the GGNS Construction Well.
Sampling of the discharge basin surface water was discontinued and the sampling frequency for the upstream and downstream surface water locations was changed from monthly to quarterly. In addition, an annual sample is to be collected at a downstream location during a liquid radwaste discharge, Vegetation sampling frequency was changed from three different sample types e
from two onsite gardens and one control location on a monthly basis to one sample type on a quarterly basis from one of the two onsite gardens and one sample type on a quarterly basis from a control location.
Milk sampling frequency was changed to quarterly for indicator locations, when e
available, with sampling of the control location only occurring when indicator locations are present.
Fish sampling was discontinued.
Sampling frequency for the downstream sediment location (SEDHAM) was changed from semiannually to annually and an annual upstream location was added.
TLDs were changed from sixteen inner and outer ring TLDs to sixteen inner / outer ring only and eight special interest areas.

E0698-125 (6/19/96) Gamma in Water and E0769-125 duplicate (6/19/96) Cs-134 Cs-134 results in 6/19/96 gamma in water sample E0698-125 and duplicate gamma in water sample E0769-125 were outside the control limits as defined in note "b" in the data table. Review of the previous three years of cross-check data indicated that a low bias for Cs-134 existed due to cascade (coincidence) summing effects.
A summing correction factor was calculated and applied to the Cs-134 yields in the software nuclide library for water. Re-analysis of the spectrum data with corrected yields produced results within the warning limits. Cs-134 results for 9/26/96 and 12/12/96 gamma in water studies were within the warning limits as defined in note "b" in the data table.
2.
E0698-125 (6/19/96) Gamma in Water Cc-141 The Ce-141 result for the 6/19/96 gamma in water sample E0698-125 was slightly outside (-3.05) the control limit. Review of the three analysis results did not indicate an outlier. The Ce-141 result of the duplicate 6/19/96 gamma in water sample E0769-125 was within control limits. No reason was determined for the out-of-control limit result of Ce-141 in the second quarter study.
Results for Ce-141 in all other gamma in water studies for 1996 were within the warning limits. No corrective actions were taken due to the single out of control limit result for Ce-141 in the second quarter study.
3.
E0882-125 (12/12/96) Gamma in Water Cr-51 The Cr-51 result for the 12/12/96 gamma in water study E0882-125 was outside (-3.59) the control limit. Review of the three results used for the average indicated an outlie.
result caused the low average.
The percent coefficients of variation calculation will be used in the future as a criteria to determine the presence of an outlier Outlier results will be discarded, usingjust two results, or the sample will be analyzed a fourth time if possible.

E0886-125 (12/12/96) Gamma in Water (Duplicate) Fe-59 4
The Fe-59 result for the 12/12/96 gamma in water sample E0886-125 was outside
{
(+3.66) the control limit. Review of the three results used for the average indicated an outlier result caused the high average.
The percent coefficients of variation calculation will be used in the future as a criteria to determine the presence of an outlier. Outlier results will be discarded, usingjust two results, or the sample will be analyzed a fourth time, if possible.
Impact Statement There is no impact on past data indicated by these interlaboratory comparison program exceptions. Environmental samples are analyzed and reported with 'a 95% confidence level that 1
the analytical result with its associated error encompasses the "true" value. As seen below,95%
of the cross-check results are within the acceptable control limits of the three normalized deviation.
