Indicated below is the annual summary of offsite doses attributable to GGNS during 2008.Inspection of the values indicate that GGNS releases were within the 1 OCFR50, Appendix I design objectives. Since there are no other fuel cycle facilities within 8 km of GGNS, 40CFR190 limits have also been met during this period.All parameters listed were calculated in accordance with the GGNS ODeM.A.Water-Related Exposure Pathways The values calculated in this sectionutilizethe information provided in Tables 2A and 28 of this report and the calculational methodology of the ODeM.Liquid Effluents Totalbodydose and critical organ doses are computed for the maximum exposed individual.

SUMMARY

(CONT'D)Organ Dose The maximum organ dose to a MEMBER OF THE PUBLIC (critical receptor)from radioiodines, tritium and particulates was calculated for this report using the most recent land use census and dispersion and deposition parameters from 2008 meteorological data.The critical receptor residence was determined to be located in the southwest sector at a distance of 1432 meters (0.89 miles)from the plant.Pathways considered for use in the organ dose calculations are inhalation, ground plane, grass/cow/meat and vegetation. There is no grass/cow/milk pathway within five miles of GGNS.It was assumed that the age group receiving the maximum dose lived at the residence and that the receptor consumed food products that were raised or produced at the residence. Average Total Body and Skin Dose Rate Individual total body and skin dose rates from exposure to a semi-infinite cloud of noble gas are computed for a location in the south sector at a distance of 644 meters (0.40 miles)from the plant.This location corresponds to the highest annual average atmospheric dispersion factor for a location at an unrestricted area within the site boundary.The total body and skin dose rates reported are the quarterly average of the maximum instantaneous dose rates determined daily during the reporting period and would represent the maximum possible dose rate received by members of the public.Air Dose From Gamma and Beta Emissions Air doses from gaseous effluents were calculated for this report using dispersion parameters from the 2008 meteorological data.The highest dispersion factor for an unrestricted area was in the south sector within the site boundary, 644 meters (0.40 miles)from the plant.Direct Radiation Direct radiation dose is calculated by subtracting average doses measured by thermoluminescent dosimeter (TLD)badges located at control locations from average doses measured by TLD badges located near the site boundary.GGNS reported measured doses in 2008 as net exposure normali%ed to 92 days.2.39E-01 1.40E+OO O.OOE+OO 1.10E+OO 3.80E+OO*Measurement units are mrad en v-tec/A RERRO1-14 Corrected Page July 9,2009 en,-WIARERRO1 - OFFSITE DOSE CALCULATION MANUAL!
