OF MONITORING RESULTS 41 5
Summary The Annual Radiological Environmental Operating Report presents data obtained through analyses of environmental samples collected for Grand Gulf Nuclear Stations (GGNS)
Radiological Environmental Monitoring Program (REMP) for the period January 1, 2003 through December 31, 2003. This report fulfills the requirements of GGNS Technical Specification 5.6.2.
To supplement the REMP, GGNS personnel collected duplicate surface water, ground water, vegetation, sediment and fish samples during the reporting period. Special samples collected during the reporting period included vegetation and venison. GGNS did not detect any plant-related radionuclides in these samples.
Radiological Environmental Monitorinp Program GGNS established the REMP in 1978 prior to the station becoming 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, water, sediment, fish and food products, as well as measuring radiation directly. GGNS also samples milk if commercial milk production is occurring within five miles of the plant.
The REMP includes sampling indicator and control locations within an 1 8-mile radius of the plant. The REMP 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 environment.
In the current year, GGNS personnel collected environmental samples for radiological analysis. They compared results of indicator 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 current year data, in many cases, showed undetectable radiation levels in the environment and near background level in significant pathways associated with GGNS.
6
Harmful Effects or Irreversible Damage The REMP monitoring did not detect any harmful effects or evidence of irreversible damage in the current year. 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 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, results did not trigger any Radiological Monitoring Program Special Reports.
Radioactivitv Not Attributable to GGNS In previous years, the GGNS REMP detected radioactivity attributable to other sources twice.
These include the 25th Chinese nuclear test explosion in 1980, and the radioactivity plume release due to reactor core degradation at the Chernobyl Nuclear Power Plant in 1986.
Comparison to Federal and State Prolprams GGNS personnel compared REMP data to federal and state monitoring programs as results became available. Historically, the programs used for comparison have included the U.S.
Nuclear Regulatory Coinmission (NRC) TLD Direct Radiation Monitoring Network and the Mississippi State Department of Health (MSDH), Division of Radiological Health.
The NRC TLD Network Program was discontinued in 1998. Historically these results have compared favorably to those from the GGNS REMP. GGNS TLD results remain similar to the historical average and continue to verify that plant operation is not affecting the ambient radiation levels in the environment.
The MSDH and the GGNS REMP entail similar radiological environmental monitoring program requirements. These programs include concurrent air sampling and splitting or sharing sample media such as water, sediment, fish and food products. Both programs have obtained similar results over previous years. The results of MSDH's monitoring program for the reporting period compared favorably with the GGNS REMP and did not indicate elevated levels of radiation or radioactivity build-up attributed to plant operations.
7
Sample Deviations
+ Milk The REMP did not include milk sampling within five miles (8 km) of GGNS in the current year due to unavailability. ODCM Specifications require collection of milk samples if available commercially within 8 km (5 miles) of the plant. GGNS personnel collected vegetation samples to monitor the ingestion pathway, as specified in ODCM Specifications Table 6.12.1-1, because of milk unavailability.
+ Required Lower Limit of Detection (LLD) Values One Air Sample [gross beta] at location AS-1 PG, nearest community, did not meet the required detection level due to reduced sample volume caused by a sample pump failure.
Results from other sample locations during the sample period were reviewed and no abnormal results were noted. Remaining LLDs during this reporting period were within the acceptable limits required by the ODCM specifications.
8
+ Air Samples The following air sample locations had reduced run times due to weather-related outages or mechanical problems. As described in footnote (a) to ODCM Specification Table 6.12.1-1, deviations from the required sampling schedule are permitted due to malfunction of sampling equipment and other legitimate reasons.

1.0 Introduction 1.l GGNS established the REMP to ensure that plant operating controls properly function to minimize any associated radiation endangerment to human health or the environment. The REMP is designed for:
Radiological Environmental Monitoring Program 0
Analyzing important pathways for anticipated types and quantities of radionuclides released into the environment.
Considering the possibility of a buildup of long-lived radionuclides in the environment and identifylng physical and biological accumulations that may contribute to human exposures.
0 Considering the potential radiation exposure to plant and animal life in the environment surrounding GGNS.
0 Correlating levels of radiation and radioactivity in the environment with radioactive releases from station operation.
1.2 Pathways Monitored The airborne, direct radiation, waterborne and ingestion pathways, as seen in Figure 1-1, are monitored as required by GGNS ODCM Table 6.12.1-1. A description of the GGNS REMP utilized to monitor the exposure pathways is provided in Table 1.1 and shown in Figures 1-2 and 1-3. GGNS may supplement this program with additional sampling in order to provide a comprehensive and well-balanced program. Only sample locations required by the ODCM are shown in Figures 1-2 and 1-3.
Section 2.0 of this report provides a discussion of sampling results with Section 3.0 providing a summary of results for the monitored exposure pathways.
11
1.3 Land Use Census GGNS personnel conduct a land use census biannually, as required by ODCM Specification 6.12.2. The purpose of this census is to identify changes in uses of land within five miles of GGNS that would require modifications to the REMP or the ODCM. The most recent land use census was conducted in 2003. The most important criteria during this census are to determine location in each sector of the nearest:
- 1) Residence
- 2) Animal milked for human consumption
- 3) Garden of greater than 50 m (500 fi ) producing broadleaf vegetation.
2 2
When performed, GGNS personnel conduct the land use census by:
0 Field surveys in each meteorological sector out to five miles in order to confirm:
P Nearest permanent residence 3 Nearest unoccupied residence 3 Nearest garden and approximate size 3 Nearest milking animal.
0 Identifjmg locations on maps, measuring distances to GGNS and recording results on surveillance data sheets.
Comparing current land use census results to previous results.
0 Contacting the Claiborne County Agent for verification of nearest dairy animals.

2.0 Interpretation and Trends of Results 2.1 GGNS did not detect any plant related gamma emitting radionuclides in the quarterly air particulate composites or Iodine-13 1 in the radioiodine cartridges during the reporting period, as has been the case in previous years.
The REMP 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 Chernobyl Nuclear Power Plant in 1986. Therefore, the airborne exposure pathway has been unaffected by the operation of GGNS and airborne concentrations continue to be at background levels.
Air Particulate and Radioiodine Sample Results Table 3.1, which includes gross beta concentrations, provides a comparison of the indicator and control means and ranges, further emphasizes that the airborne pathway continues to remain at background levels. In the absence of plant-related gamma radionuclides, gross beta activity is attributed to naturally occurring radionuclides.
Consistent trends are present for control and indicator locations. This further supports the presence of naturally occurring activity.
2.2 Thermoluminescent Dosimetry Sample Results GGNS calculates dose by subtracting shield readings from control and indicator location readings and reports measured dose as net exposure normalized to 92 days.
GGNS relies on comparison of the indicator locations to the control location as a measure of plant impact. Gamma radiation dose in the reporting period is compared to control location readings for previous years as shown in Figure 2-1.
GGNS comparison of the indicator results to the control and to previous indicator results, as seen in Figure 2-1 and Table 3.1, indicates that plant operations had no significant impact on ambient radiation levels during the reporting period. Levels continue to remain at or near background.

2.3 Water Sample Results Analytical results for surface water and groundwater samples were similar to those reported in previous years.
Surface water samples were collected from two indicator and one control location and analyzed for gamma emitting radionuclides and tritium. Plant related gamma emitting radionuclides and tritium remained undetectable in the upstream and downstream Mississippi River locations, which is consistent with preoperational and previous operational years. In addition, gamma emitting radionuclides and tritium were undetectable in the downstream sample collected during a liquid radwaste discharge.
Groundwater samples were collected from two locations (indicator and control) and analyzed for gamma emitting radionuclides and tritium. GGNS did not detect any plant related gainma emitting radionuclides or tritium in groundwater samples during the reporting period.
Based on review of results and previous historical data, GGNS concluded that plant operations had no significant impact on this pathway during the reporting period.
2.4 Sediment Sample Results Sediment samples were collected from two ODCM Specification locations (indicator and control) and analyzed for gamma emitting radionuclides. In this reporting period, plant related gamma emitting radionuclides were below detectable limits in the upstream (control) and downstream (indicator) locations.
A review of REMP data collected at the control location from 1983 through 2002 indicates the Cesium-137 concentration has ranged from less than detectable to 200 pCiiKg. The presence of Cesium-1 37 is attributed to atmospheric weapons testing.
2003 REMP data is consistent with the previous monitoring periods. Therefore, GGNS concluded that plant operations had no significant impact on this pathway during the reporting period.
25
2.5 Milk Sample Results GGNS personnel did not collect milk samples within five miles of the site in the reporting period due to thc absence of milking animals. Since there are no dairies within five miles of GGNS, it is concluded GGNS' operation had no impact on this pathway.
2.6 Fish Sample Results Fish samples were collected from two locations (indicator and control) and analyzed for gamma emitting radionuclides. GGNS did not detect any plant related gamma emitting radionuclides in fish samples during the reporting period, as has been the case in preoperational and previous operational years. These results indicate that this pathway has not been affected by plant operations.
2.7 Food Product Sample Results Food product samples were collected f'rom control and indicator locations when available and analyzed for gamma emitting radionuclides. GGNS did not detect any plant related gamma emitting radionuclides in vegetation samples during the reporting period.
Nuclides detected previously at the control and indicator locations are attributed to the Chernobyl release and atmospheric weapons testing. These results indicate that this pathway has not been affected by plant operations.
Five special samples of vegetation were collected at an offsite location to supplement the REMP. The location is under evaluation for a control sample location. GGNS did not detect any plant related gamma emitting radionuclides in vegetation samples during the reporting period.
One special sample of venison was collected on the GGNS property to supplement the REMP. GGNS detected Cesium-137 at a level of 42.4 pCi/kg. This value is less than the detection level requirement of 150 pCi/kg and significantly less than the reporting level of 2000 pCi/kg. Based on detection of Cesium-137 in sediment samples from the control location which ranged from non-detectable to 200 pCi/kg, the presence of Cesium-I37 is attributed to atmospheric weapons testing. These results indicate that this pathway has not been affected by plant operations.
26
2.8 Land Use Census Results Methods utilized include: visual surveys, door to door surveys, telephone interviews, GPS, Aerial Photography, and consultation with the local county agent concerning dairy production in Claiborne County.
During the survey the following questions were asked:
1). Name of occupant 2). Address 3). Number of people residing at residence 4). Age group of occupants 5). Any farm animal raised for human consumption 6). Any dairy production 7). Maintain a garden Changes from the 2003 Land Use Census were evaluated in accordance with GGNS surveillance 06-EN-S000-0-0002 sections 5.1.3.b(2) and 5.2. The differences were compared to the locations and assumptions used in calculations for compliance with the Offsite Dose Calculation Manual (ODCM), LCO 6.1 1.6. It was determined that the locations and assumptions currently used in ODCM, revision 26, are more conservative than any of the changes. Other determinations from the 2003 Land Use Census results are:
The closest child age group is in Sector A (North) at 1.78 miles, GGNS ODCM calculations currently uses the maximum calculated dose from either Sector L (Southwest) at 0.89 miles or Sector C (Northeast) at 0.67 miles.
Doses calculated at Sector A would be lower.
One location recorded as unoccupied in the previous land use census is now occupied, sector E (East) at 0.83 miles. As noted in the previous Land Use Census, because of distance and downwind location it would not produce a higher calculated dose.
Because of downwind location and/or distance from the site, in no case will the occupancy of an existing unoccupied residence cause any ODCM critical receptor calculation results to be less conservative.
No additional sampling locations are required as the onsite gardedvegetation sampling location (Sector J, 0.4 miles) is more conservative than changes identified in the land use census.
Cattle are raised for human consumption (most notably Sector H, J, and K).
GGNS uses the Grass/Cow/Meat pathway.
27
2.8 Land Use Census Results, continued The milk pathway does not need to be activated, no dairy production is occurring within 5 miles.
Sectors M, N, P, Q are remote areas in which the primary use is hunting. Area was surveyed by vehicle and aerial photographs. Also, all areas in Louisiana within 5 miles belong to the Winter Quarters exclusive hunting club. From the previous census, personnel at entrance gate were interviewed and responded, No permanent residence or gardens, the area is posted.
Gardens, regardless of size, were included in the census data.

2.9 Interlaboratory Comparison Results River Bend Station (RBS) Environmental Laboratory analyzed interlaboratory comparison samples to fulfill the requirements of the ODCM Specifications 6.12.1., Radiological Environmental Monitoring Report, contains these results in Table 9.1. GGNS review of RBS interlaboratory comparison indicated that 97.5% of the sample results for accuracy and 100% of the results for precision were within the acceptable control liinits of the three normalized deviations. For those sample results outside the acceptable control limits, GGNS and RBSs review indicated no impact on previously reported data. also provides additional discussion regarding sample results outside the acceptable control limits.

- a. The "known" values are listed with a range reflecting control (3 sigma) limits.
- b. The normalized deviation from the "known" value is computed from the deviation and the standard error of the mean; r2.000 is the warning limit and r3.000 is the control limit. This is a measure of accuracy of the analytical methods.
- c. The normalized range is computed from the mean range, the control limit, and the standard error of the range; +2.000 is the warning limit and +3.000 is the control limit. This is a measure of precision of the analytical methods.
- d. The results reported were out of the control limits.

Table 9.1 Sample Type: Interlaboratorg ComDarison Analysis: Gross Beta, Tritium, Iodine-1 3 1 and Gamma Isotopic Exceptions:
There was one result outside the control limits for accuracy in the 2003 cross check program participation studies. This result was in a gamma isotopic analysis of a water sample.
The result outside the control limits for accuracy was in the analysis of the nuclide 1-131 in sample study E3755-125 of 6/12/2003. RBS normalized-deviation for the analysis was +3.06 with control limits of 23.00.
This high bias result is considered conservative and is considered as having no impact on past results of the program. Remaining 1-131 results for cross check samples were within control limits for the year 2003.
