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 levels in significant pathways associated with GGNS.

Comparison to Federal and State Programs GGNS personnel compared REMP data to federal and state ITIonitoring programs as results became available. Historically, the programs used for comparison have included the U.S.

Nuclear Regulatory Commission (NRC) Thermoluminescent Dosimeter (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 compared favorably to those from the GGNS REMP.

The MSDH and the GGNS REMP have similar radiological environmental monitoring program requirements. These programs include concurrent air sampling and sharing sample media such as water, sedin1ent, fish and food products. Both programs have obtained similar results. 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.

1.0 Introduction 1.1 Radiological Environmental Monitoring Program GGNS established the REMP to ensure that plant eontrols funetion to minimize any assoeiated radiation endangerment to human health or the environment. The REMP is for:

• Analyzing important pathways for antieipated types and quantities of radionuelides released into the environment.

• Considering the possibility of a buildup of long-lived radionuelides in the environment and identifying physieal and biologieal aeeumulations that may eontribute to human exposures.

• Considering the potential radiation exposure to plant and animal life in the environment surrounding GGNS.

• Correlating levels of radiation and radioaetivity m the environment with radioaetive relea:ses from station operation, 1.2 Pathways Monitored The airborne, direet radiation, waterborne and ingestion pathways, as seen in Figure 1-1, are monitored as required by GGNS aDCM Table 6.12.1-1. A deseription 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.

1.3 Land Use Census GGNS personnel conduct a land use census biannually, as required by aDCM Specification 6.1 Data for the most recent land use census is included. The purpose of this census is to

,r1onf",1r" '-'JlIUII M \.,.:, in uses of land within miles of GGNS that would require modifications to the REMP or the aDCM most important criteria during this census are to determine location in each sector of the nearest:

I)

2) Animal milked for human consumption 2

3) Garden of than 50 m (500 ft ) producing broadleaf vegetation.

GGNS personnel conduct the land use census by:

• Conducting field surveys in each meteorological sector out to five miles in order to confirm:

Y Nearest permanent residence Y Nearest unoccupied residence Y Nearest garden and approximate size Y Nearest milking animaL

• Identifying locations on maps, measuring distances to GGNS and recording results on surveillance data sheets.

• Comparing current land use census results to previous results.

• 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 plant related gamma emitting radionuclides in the quarterly air particulate composites or Iodine-l 31 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 Chinese nuclear test in 1980, and the radioactive due to reactor core degradation at Chernobyl Nuclear Power Plant in 1986.

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 beta concentrations, provides a comparison of the indicator and control means and ranges, and 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 based on the similar trends seen when comparing results of control and indicator locations.

2.2 Thermoluminescent Dosimetry Sample Results GGNS calculates dose by subtracting shield readings from control and indicator location rea,QUlgs 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 locations M-21 (Sector J, 0.4 miles), M-98 (Sector H, 0.5 miles) and M-99 (Sector K, 0.4 miles) direct radiation levels continue to remain at or near background. The dose rate at these three locations is a result of increased Nitrogen-16 levels associated with hydrogen injection. Hydrogen injection into the feedwater system provides protection against Intergranular Stress Corrosion of plant components. Dose rates at locations M-21 [3.2 millirem per quarter], M-98 [0.8 millirem per quarter] and M-99 [3.3 millirem per quarter] remain well below the limitations of 10CFR20.1301(a)(2) and 10CFR 20.1302(b)(2)(ii).

2.3 Water Sample Results

'0 TYH,,\I ""<" were collected from three indicator locations (Outfall 007, MRDOWN, and one control location (MRUP) and analyzed for gamma

\vUlll .... "UF, ra(1l0]nW~lHles and tritium. Plant related gamma emitting radionuclides undetectable in River locations, which is consistent with operational years. Tritium was measured just above the detection pCi/l) in one downstream sample. A duplicate of this sample measured All other upstream and downstream tritium measurements were less than Storm waters contribute to Outfall 007 and can include tritium as a result of washout and precipitation entrainment of routine, previously monitored gaseous effluents. As a result, tritium is occasionally observed. When detected, tritium was measured at an average concentration of 12613 +/- 367 pCi/1 at the Outfall 007 (indicator) location. The maximum tritium measurement was in February following an approximately six inch snowfall.

In addition to the tritium samples required by the REMP, five special surface water samples for gamma were at the Outfall 007 location. Plant related gamma emitting radionuclides 10\'011"\,,,,11 undetectable in these samples.

on of results and historical data, GGNS concluded that plant operations had no significant impact on this pathway during the reporting period.

Groundwater samples were collected from two locations (indicator and control) and analyzed for gamma emitting radionuclides and tritium. Indicator includes three wells located on site property. GGNS did not detect any plant related gamma emitting radionuclides in groundwater samples during the reporting period. One Indicator well (Construction Well #1) measured just above the detection level (738 +/- 186 pCilL ) in the third quarter sample. All previous and subsequent samples for Indicator and Control samples were less than detectable for tritium.

Based on review of results and 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 concentrations in the upstream (control) and downstream (indicator) locations.

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 GGNS, and based on non-detectable radioiodine and gamma radionuclides in air and vegetation samples, it is concluded GGNS' operation had no impact on this pathway.

26

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 plant related gamma emitting radionuclides in fish samples (edible portions) 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 Vegetation samples were collected from control and indicator locations when available and analyzed for Iodine-131 and gamma emitting radionuclides. GGNS did not detect any plant related Iodine-I 3 I or 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.

Special venison was collected on the GGNS property to supplement the REMP. GGNS did not detect any plant related gamma emitting radionuclides in this venison sample during the reporting period.

2.8 Land Use Census Results Results from the Land Use Census performed October 5-12,2010 are included in this report.

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 information was obtained:

I) location of occupied and unoccupied residence

2) location of dairy production

3) location of gardens.

27

~"\A .. t"".h> from the Land Use Census were and the 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 are more conservative than any of the Determinations from the most recent Land Use Census results are:

• Because of downwind location and/or distance from the site, in no case will the occupancy of an existing unoccupied residence cause any existing ODCM critical receptor calculation results to be less conservative.

• No additional sampling locations are required as the onsite 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 (most notably Sector H, J, and K).

GGNS uses the Grass/Cow/Meat pathway.

• The milk pathway does not need to be activated because no commercial dairy production is occurring within 5 miles, as referenced by ODCM Table 6.12.1- I.

• Sectors M, N, P, and Q are remote areas in which the primary use is hunting. Area was surveyed by vehicle and aerial photographs.

• Gardens, regardless of size, were included in the census data.
