Introduction 1.1 Radiological Environmental NIOIIitOI-iII2 Pr02rani GGNS established the REMP to ensure that plant operating controls properly function to minimize any associated radiation endan(,ernient to to human health or the environment. The REAP is designed for:

• analyzing important pathways for anticipated types and quantities of of radionuclides released into, the enN,ironi-nent .

• Bering the Considering the possibility possibility of of aa buildup buildup of of long-lived long-lived radionuclides radionuclides in in the the ironment and environment and identifying identifying physical physical andand biological biological accumulations accumulations that that may contri 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 Pathways Monitored The airborne, direct radiation, waterborne and ingestion pathways, as seen seen in in Figure 1-1, are monitored as required by GGNS aDCM 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.

.3 Iran Use Census GGNS personnel conduct a land use census biannually, as required by ODCNT Specification 6.12 .2 . Data for the most recent land use census is included . 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 ODC-'.,\/l The most important criteria during this census are to determine location in each sector of the nearest:

nearest:

1) widen 2)) Animal milked for Animal milked for human onsumption human consumption 22 22 .

ater ttan

3) Garden of greater h 50 m (500(500 ft producIng broadleaf ft )) producing vegetation broadleafvegetation.

When performed, GGNS personnel conduct the land land use use census by:

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

~ Nearest permanent residence

~ Nearest unoccupied residence

~ Nearest garden and approximate size

~ 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.

Water Sample Results Surl'ace `eater samples were collected from t1lree indicator locations (Outfall 007, MRDOWN, and MR-DOWN During Discharge) and one control location (MRUP) and analyzed for gamma emitting radionuclides and tritium. Plant related gamma emitting radionuclides acid tritium remained undetectable in the upstream and do<<-nstrearil Mississippi River locations, which is consistent with preoperational and previous operational years . Storm waters contribute to Outfall 007 and can include tritium as a result of washout and entrainment of routine, previously monitored gaseous effluents .

As a result, tritium levels below the minimum detection level requirement (3000 pCi/L) are occasionally observed. N~-"lien detected, 'I'rlt*ILII-ll NN,as measuz-ed at aii av- ;rat 11celitr*ation of 545 +/- 253 oCi/L iii tlic Outfall 007 (indicato In addition addition to to the itium samples the tritium samples required by the required by the REMP, REMP, four four spec special surface water samples samples for for gamma gamma were were collected collected at at the the flutfall 007 location.

emitting radionuclides remained in these samples.

Based on review of results and historical data, GGNS GGNS concluded that plant operations ad had no significant pact 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. 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 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 aDeM 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 downstreanl (indicator) locations.

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

2.5 Milk Sample pie Results Results GGNS personnel personnel diddid not collect milk samples not collect within five samples within five miles miles ofof the the site site the eporting period due due toto the the absence absence of of milking milking animals . SinceSince there there are are no no dairi dairies ithin five miles of GGNS, it it is i concluded concluded GGNS' operation operation had.

6 Fish Sample Results Fish samples were collected from two locations (indicator and control) and analyzed for gamma emittim-, radionuclides . GGiN'S did not detect any plant related -amma emitting radionuclides in fish samples during the reporting period, as has been the case in preoperational and pre,,,,ious operational years . These results indicate that this pathway has not been affected by plant operations .

2.7 Food od Produ Productt (Vegetation)

(Vegetation) el Samp esults Sample Results Food Food productproduct samples were were collected collected from control control and and indicator locations when indicator locations when fable and available and analyzed for gamma emitting ra radionuclides. GGNS did not detect any plant related fated gamma amma, emitting emittinv- radionuc radionuclides in vegetation samples during the reporting period. Nuclides fides dedetected previously Jy at at the control and indicator locations are attributed Cherno to the Chemobyl release and atmospheric weapons testing. These results indicate that that this pathway has not been affected by plant operations.

One sanlple of vegetation was collected at an onsite location to supplement the REMP.

GGNS did not detect any plant related gamma emitting radionuclides in this vegetation sample during the reporting period.

2.8 Land Use Census Results Results from the Lalld Use Census perfornled April 9-14, 2008 are il1cluded itl this report. Methods utilized include: visual surveys, door to door door surv surveys, telephone interviews, GPS, Aerial Photography, and consultation with the the local county agent local county 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 fann animal raised forr human co human consumption 6). Any dairy production 7).
