SUMMARY
OF MONITORING RESULTS 35 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, 2004 through December 31, 2004. 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 Jlonitoring 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 fi-om 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 harmfil effects or evidence of irreversible damage in the current year. Therefore, no analysis or planned course of action to alleviate problems was necessary.
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.
Radioactivity 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 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 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 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.

AS-3 61VA 99.9%
AS-7 UH 99.9%
+ TLDs TLD station M-48 (Outer Ring, Sector K, 4.8 miles) was displaced from its designated location by unknown causes during the 1 quarter of 2004 This data was excluded from reporting. Although the 1 quarter exposure at location M-48 is unknown, GGNS' review of results for similarly located TLDs indicated no abnonnal readings.
9
+ Missed Samples There were no missed samples in the reporting period.
+ Unavailable Results GGNS received analytical results in adequate time for inclusion in this report.
addition, GGNS review identified no missing results.
In Program Modifications No program modifications occurred during the reporting period.
Attachments contains results of TLD, air, water, sediment, fish, food products and special samples collected. TLDs were analyzed by Waterford-3 Dosimetry. All remaining samples were analyzed by River Bend Stations (RBS) Environmental. Attachment 1 also contains RBS results from participation in the interlaboratory coinparison program.

1.0 Introduction 1.1 Radiological E ~ ~ i r o n ~ e ~ t ~ ~
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:
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 identiQing 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.
0 Correlating levels of radiation and radioactivity in the environment with radioactive releases fi-om 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.
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. Details of the 2003 Land Use Census were included in the 2003 AREOR. The next Land Use Census will be conducted in 2005.

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-1 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.
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 Thermolumineseent 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.
With the exception of TLD location M-21 (Sector J, 0.4 miles), levels continue to remain at or near background. An increase in the dose rate at location M-21 was due to implementation of moderate hydrogen injection to the feed water system. Hydrogen injection provides protection against Intergranular Stress Corrosion of plant components. An increase in direct radiation dose rates associated with implementation of hydrogen injection has been documented at other nuclear power plants. This increase is not a result of increased liquid or gaseous releases to the environment. Location M-2 1 dose rate of 3.7 millirem per quarter greater than the Control location M-14 (sector 3, 18.0 miles) remains well below the limitations of 10 CFR 20.1301(a)(l) and 20CFR 20.1302@)(2)(ii).

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 gamma 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 fi-om 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 concentrations in the upstream (control) location. In this reporting period, Cobalt-60 was detected at 17.87 rt 10.26 pCi/kg and Cesium-137 was detected at 15.48 rt 8.39 pCi/kg in the downstream (indicator) location.
A review of REMP data collected at the downstream location from 1983 through 2003 indicates the Cesium-137 concentration has ranged from less than detectable to 300 pCi/Kg. The presence of Cesium-137 is attributed to atmospheric weapons testing.
From 1983 through 2003 the concentration of plant related gamma emitting radionuclides similar to Cobalt-60 [Manganese-%, Cobalt-581 has ranged from less than detectable to 20 pCi/kg. Cobalt-60 at the concentration of 17.87 If: 10.26 pCi/kg is near the detection level for this nuclide and was less than detectable in a duplicate sample.
Based on the above review, 2004 REMP data is consistent with the previous monitoring periods. Therefore, GGNS concluded that plant operations Mad no significant impact on this pathway during the reporting period.
25
2.5 Milk Sample Results GGNS personnel did not collect inilk samples within five i d e s of the site in the reporting period due to the 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 from 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 did not detect any plant related gamma emitting radionuclides in the venison sample during the reporting period.
26
2.8 Land Use Census Results The next Land Use Census will be conducted in 2005.
27
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.
Attachment I, Radiological Environmental Monitoring Report, contains these results in Table 9.1. GGNS review of RBS interlaboratory comparison indicated that 100%
of the sample results for accuracy and 100% of the results for precision were within the acceptable control limits of the three normalized deviations.

= Gross beta; 1-131 = Iodine-131; H-3 = Tritium; GS = Gamma scan.
LLD = Required lower limit of detection based on GGNS ODCM Table 6.12.1-3.
Mean and range based upon detectable measurements only. Fraction of detectable measurements at specified locations is indicated in parenthesis (F).
Where applicable, locations are specified by name, distance from reactor site and meteorological sector.
Nsn-routine results are those which exceed ten times the control station value. If no control station value is available, the result i s considered non-routine if it exceeds ten times the preoperational value for the location.
LLD is not defined in GGNS ODCM Table 6.12.1-3.
