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, 2001 through December 3 1, 2001.
This report fulfills the requirements of GGNS Technical Specification 5.6.2.
During 2001, Manganese-54, Cobalt-60 and Cesium-137 were detected in the special sediment sample collected from the barge slip.
GGNS review of results from this area indicates the following:
l Presence of radioactivity at this area is attributed to materials present in the liquid discharges.
l Cesium-137 is attributed to past atmospheric weapons testing.
l Levels of radioactivity are stable in comparison to previous years.
To supplement the REMP, GGNS personnel collected duplicate surface water, ground water and fish samples during 2001. Special samples collected in 2001 included venison. GGNS did not detect any plant-related radionuclides in these samples.
Radiological Environmental Monitoring 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 18-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 enviromnent.
In 2001, 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 2001 data, in many cases, showed undetectable radiation levels in the environment and near background level in significant pathways associated with GGNS.
Harmful Effects or Irreversible DamaPe The REMP monitoring did not detect any harmful effects or evidence of irreversible damage in 2001. 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, 2001 results did not trigger any Radiological Monitoring Program Special Reports.
Radioactivity Not Attributable to GGNS 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 Programs 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 Commission (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 to those Tom the GGNS REMP. GGNS TLD results continue to 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.
Sample Deviations
+ Milk The REMP did not include milk sampling within five miles (8 km) of GGNS in 2001 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 All LLDs during this reporting period were within the acceptable limits required by the technical specifications.
+ Air Samples The following air sample locations had reduced run times due to weather-related outages or mechanical problems.
However, required LLDs were achieved in all cases. As described in footnote (a) to ODCM Specification Table 6.12. l-l, deviations are permitted from the required sampling schedule due to malfunction of sampling equipment and other legitimate reasons.

Based on the total sample collection period being reduced by 6.95 hours0.0011 days <br />0.0264 hours <br />1.570767e-4 weeks <br />3.61475e-5 months <br /> as a result of these deviations, air samples were collected 99.92 % of the available time.
TLDs TLD station M-48 (Mont Gomer Road) was displaced by unknown causes from its designated location for a brief period during the first quarter of 2001. Upon notification from a citizen that the TLD had been found, GGNS personnel returned the TLD to its designated location. Although exposure during the displaced period is unknown, GGNS review of third quarter results for this TLD indicate no impact from the displacement.
Missed Samples In 2001, there were no missed samples.
Unavailable Results GGNS received analytical results in adequate time for inclusion in this report.
In addition, GGNS review identified no missing results.
Prowam Modifications ODCM Table 3.0-2, which lists REMP sampling locations, was modified in 2001. One of two sample locations for food products was deleted from the table. The more conservative location was retained. The location retained ensures the highest probability of detection of radioactive material deposited from gaseous effluents. This modification was implemented in ODCM Revision 23.
Attachments contains results of air, TLD, water, sediment, fish, food products and special samples collected in 2001. TLDs were analyzed by Waterford-Dosimetry. All remaining samples were analyzed by River Bend Stations (RBS) Environmental Laboratory. also contains RBS participation in the interlaboratory comparison program during 200 1.
1.0 Introduction 1.1 Radiological Environmental Monitoring Program 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:
l Analyzing important pathways for anticipated types and quantities of radionuclides released into the environment.
l Considering the possibility of a buildup of long-lived radionuclides in the environment and identifying physical and biological accumulations that may contribute to human exposures.
l Considering the potential radiation exposure to plant and animal life in the environment surrounding GGNS.
l 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 l-l, 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 l-2 and l-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 l-2 and l-3.
Section 2.0 of this report provides a discussion of 2001 sampling results with Section 3.O providing a summary of results for the monitored exposure pathways.
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 important criteria during this census is to determine location in each sector of the nearest:
- 1) Residence
- 2) Animal milked for human consumption
- 3) Garden of greater than 50 m2 (500 ft2) producing broadleaf vegetation.
Land Use Census (eontd)
GGNS personnel conduct the land use census by:
l Field surveys in each meteorological sector out to five miles in order to confirm:
P Nearest permanent residence P Nearest unoccupied residence
> Nearest garden and approximate size
> Nearest milking animal.
6 Identifying locations on map, measuring distances to GGNS and recording results on surveillance data sheets.
l Comparing current land use census results to previous results.
l Contacting the Claiborne County Agent for verification of nearest dairy animals.

2.0 Interpretation and Trends of Results 2.1 Air Particulate and Radioiodine Sample Results GGNS did not detect any gamma radionuclides in the quarterly air particulate composites or Iodine-l 3 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.
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 gamrna radionuclides, gross beta activity is attributed to naturally occurring radionuclides.
2.2 Thermoluminescent Dosimetry Sample Results GGNS reports measured dose as net exposure (field reading less [transit + shield reading]) normalized to 92 days and relies on comparison of the indicator locations to the control as a measure of plant impact. Gamma radiation dose in the reporting period is compared to control location readings and indicator historical readings for previous years as shown in Figure 2-l.
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 the ambient radiation levels are unaffected by plant operations. Levels continue to remain at or near background.

2.3 Water Sample Results Analytical results for 2001 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 radionuclides and tritium. Gamma 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 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 radionuclides and tritium. GGNS did not detect any gamma 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 2001.
2.4 Sediment Sample Results Sediment samples were collected from two ODCM Specification locations (indicator and control) and analyzed for gamma radionuclides. In 2001, gamma radionuclides were below detectable limits in the upstream and downstream locations, which is consistent with the preoperational and operational monitoring periods. Therefore, GGNS concluded that. plant operations had no significant impact on this pathway during 2001.
Manganese-54, Cobalt-60 and Cesium-137 were detected at the onsite barge slip location during this reporting period.
This sample location supplements the REMP and is collected as a special sample. GGNS personnel attribute the presence of radioactivity at this location years to buildup from materials present in liquid discharges. Figure 2-2 shows that radionuclide concentrations in the onsite barge slip are consistent with the composition of the plant liquid releases and are not increasing at a significant rate.
2.5 Milk Sample Results GGNS personnel did not collect milk samples within five miles of the site in the reporting period due to the absence of milking animals. Since there are no dairies within five miles of the GGNS, it is concluded GGNS operation had no impact on this pathway in 2001.
2.6 Fish Sample Results Fish samples were collected from two locations (indicator and control) and analyzed for gamma radionuclides.
GGNS did not detect any gamma radionuclides in fish samples during the reporting period, as has been the case in preoperational and 21
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 when available from control and indicator locations in 2001 and analyzed for Iodine-l 3 1 and gamma radionuclides. GGNS did not detect any gamma radionuclides in vegetation samples during the reporting period.
Nuclides detected previously at the control and indicator locations are attributed to the Chernobyl accident and weapons testing. These results indicate that this pathway has not been affected by plant operations.
A special sample of venison was collected on the GGNS property during 2001 to supplement the REMP.
GGNS did not detect any gamma radionuclides in this sample.
2.8 Land Use Census Results Prior to the 2001 land use census, Environmental Sample Location Maps were used to determine distances and sectors. In 2001 a Global Positioning System (GPS) was purchased to improve distance readings and determine degrees from true north (sectors). The GPS used was the Garmin etrex. Waypoints for locations of interest were marked using the GPS and transferred to commercial GPS software, ExpertGPS ver 1.08, TopoGrafix.
The points of interest were overlaid onto aerial photographs and verified, i.e. waypoints were at the expected location, usually on driveways or front door area of houses. Some waypoints were adjusted by moving them from the driveway area to the house roof on the aerial map.
Distances and sectors were determined by using the softwares waypoint report with metric units for distances.
The report was exported to Excel and metric units were converted to statute miles using 1609.344 or 1.609344 depending on whether the units were in meters or kilometers.
22
2.8 Land Use Census Results, continued Methods utilized in the 2001 Land Use Census included: visual surveys, door to door surveys, telephone interviews, GPS, Aerial Photography, 911 address system and consultation with the local county agent concerning dairy production in Claibome 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 1999 Land Use Census were evaluated and the differences were compared to the locations and assumptions used in calculations for compliance with the Offsite Dose Calculation Manual (ODCM), LCO 6.11.6. It was determined that the locations and assumptions currently used in ODCM, Revision 23, are more conservative than any of the changes. Other determinations from the 2001 Land Use Census results are:
The closest child age group is in Sector A (North) at 1.78 miles, GGNS ODCM calculations currently uses a default child in the highest D/Q Sector, L (Southwest) at 0.89 miles. During the census interviews no infants were reported and no milk pathway exist within 5 miles.
In no case will the occupancy of an existing unoccupied residence cause any ODCM calculation results to be less conservative.
No additional sampling locations are required as the onsite garden/vegetation sampling location (Sector J, 0.4 miles) is more conservative than changes identified in the land use census.
Cattle are raised for human consumption (Sector H, J, and K). GGNS includes the Grass/Cow/Meat pathway in ODCM dose calculations.
The milk pathway does not need to be activated, no dairy production is occurring within 5 miles.
23
2.8 Land Use Census Results, continued Sectors M, N, P and Q are remote areas primarily used for hunting. Area was surveyed by vehicle, aerial photographs and 911 address data. Also, all areas in Louisiana within 5 miles belong to the Winter Quarters exclusive hunting club.
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 for GGNS to fi&ll the requirements of the ODCM Specifications 612.1., 200 1 Radiological Environmental Monitoring Report, contains these results in Table 9.1. GGNS review of RBS interlaboratory comparison indicated that 98.1% of the sample results for accuracy and 100% of the results for precision were within the acceptable control limits 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. Attachment 1 also provides additional discussion regarding sample results outside the acceptable control limits.

0.069 NOTES (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; k2.000 is the warning limit and f3.000 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: Interlaboratory Comparison Analysis: Gross Beta, Tritium, Iodine-13 1 and Gamma Isotopic Exceptions:
There was one result outside the control limits for accuracy in the 2001 cross check program participation studies. This result was in a gamma isotopic analysis of water sample.
The study result outside the control limits for accuracy was in the analysis of the nuclide Fe-59 in sample study E2817-125 of 9/20/2001, which is a duplicate sample for that study. The Fe-59 result was within control limits for the other water sample in this quarterly study. RBS normalized-deviation for the analysis was t-3.24 with control limits of h3.00. This high bias result is conservative and is considered as having no impact on past results of the program. The bias high result for Fe-59 is contributed to coincidence summing effects inherent in the calibration. Fe-59 was not detected in any of the REMP samples. Fe-59 results were all within control limits in other cross check samples for the year 2001. The normalized-deviations for Fe-59 in other samples during year 2001 were 1.91,2.63,2.84, and 2.10.
98.1% of interlaboratory cross check results were within control limits for accuracy and 100% of results were within control limits for precision.
