4.0 EVALUATION OF DOSE 4.1 DOSE FROM ENVIRONMENTAL MEASUREMENTS Annual doses to maximum exposed individuals were estimated based on measured concentrations of radionuclides in 2002 MNS REMP samples. The primary purpose of estimating doses based on sample results is to allow comparison to effluent program dose estimates.
Doses based on sample results were calculated using the methodology and data presented in NRC Regulatory Guide 1.109. Measured radionuclide concentrations, averaged over the entire year for a specific radionuclide, indicator location and sample type, were used to calculate REMP-based doses. Where applicable, average background concentration at the corresponding control location was subtracted.
Regulatory Guide 1.109 consumption rates for the maximum exposed individual were used in the calculations. When the guide listed "NO DATA" as the dose factor for a given radionuclide and organ, a dose factor of zero was assumed.
Maximum dose estimates (Highest Annual Mean Concentration) based on drinking water, fish, and shoreline sediment sample results are reported in Table 4.1-A. The individual critical population and pathway dose calculations are reported in Table 4.1-B.
REMP-based dose estimates are not reported for airborne radioiodine, airborne particulate, milk, or broadleaf vegetation sample types because no radionuclides other than naturally occurring K-40 and Be-7 were detected in the samples. Dose estimates are not reported for surface water because sampled surface water is not considered to be a potable drinking water source. Exposure estimates based upon REMP TLD results are discussed in Section 3.9.
The maximum environmental organ dose estimate for any single sample type (other than direct radiation from gaseous effluents) collected during 2002 was 5.84E-02 mrem to the maximum exposed child's liver, total body, thyroid, kidney, lung and GI-LLI from drinking water.
4.2 ESTIMATED DOSE FROM RELEASES Throughout the year, dose estimates were calculated based on actual 2002 liquid and gaseous effluent release data. Effluent-based dose estimates were calculated using the RETDAS computer program which employs methodology and data presented in NRC Regulatory Guide 1.109. The 2002 MNS Annual Radioactive Effluent Release Report (reference 6.6) included calendar year dose estimates for the location with the highest individual organ dose from liquid and gaseous effluent releases. These reported doses are shown in Table 4.1-A along with the corresponding REMP-based dose estimates.
Section 4 - Page I
The effluent-based liquid release doses are summations of the dose contributions from the drinking water, fish, and shoreline pathways. The effluent-based gaseous release doses report noble gas exposure separately from iodine, particulate, and tritium exposure. For noble gas exposure there is no critical age group; as the maximum exposed individuals are assumed to receive the same doses, regardless of their age group. For iodine, particulate, and tritium exposure the effluent-based gaseous release doses are summations of the dose contributors from ground/plane, inhalation, milk and vegetation pathways.
4.3 COMPARISON OF DOSES The environmental and effluent dose estimates given in Table 4.1-A agree reasonably well. The similarity of the doses indicate that the radioactivity levels in the environment do not differ significantly from those expected based on effluent measurements and modeling of the environmental exposure pathways. This indicates that effluent program dose estimates are both valid and reasonably conservative.
There are some differences in how effluent and environmental doses are calculated that affect the comparison. Doses calculated from environmental data are conservative because they are based on a mean that includes only samples with a net positive activity versus a mean that includes all sample results (i.e. zero results are not included in the mean). Also, airborne tritium is not measured in environmental samples but is used to calculate effluent doses.
In calculations based on liquid release pathways, drinking water and fish consumption were the predominant dose pathways based on environmental and effluent data. The maximum total organ dose based on 2002 environmental sample results was 1.09E-01 mrem to the child liver. The maximum total organ dose of 7.82E-02 mrem for liquid effluent-based estimates was to the child liver.
No environmental doses resulted from the gaseous pathway in 2002 because broadleaf vegetation, milk, and airborne radioiodines and particulates indicated no activity. The gaseous effluent dose is due to tritium on broadleaf vegetation.
Noble gas samples are not collected as part of the REMP, preventing an analogous comparison of effluent-based noble gas exposure estimates.
The doses calculated do not exceed the 40CFR190 dose commitment limits for members of the public. Doses to members of the public attributable to the operation of MNS are being maintained well within regulatory limits.

Table 5.0-B Footnote Explanations (1) State of NC Division of Radiation Protection TLD Cross-Check, Fall 2002 There was an unusual amount of time between anneal, irradiation and readout for the Fall 2002 Environmental Crosscheck with the State of NC Division of Radiation Protection. Normal times between irradiation and readout are typically less than 7 days. In the Fall 2002 crosscheck, due to the ice storm and holiday season, the time between irradiation and readout was 18 days. Fading correction was not applied for the report results; fading correction is typically NOT USED.
When fading correction was applied, the cross-checks were within acceptance criteria. Fading correction will be applied to future cross-checks.
Additional information is documented in PIP G-03-00021.

APPENDIX A ENVIRONMENTAL SAMPLING ANALYSIS PROCEDURES Appendix A- Page I
APPENDIX A ENVIRONMENTAL SAMPLING AND ANALYSIS PROCEDURES Adherence to established procedures for sampling and analysis of all environmental media at McGuire Nuclear Station was required to ensure compliance with Station Selected Licensee Commitments. Analytical procedures were employed to ensure that Selected Licensee Commitments detection capabilities were achieved.
Environmental sampling and analyses were performed by EnRad Laboratories, Dosimetry and Records, and Fisheries and Aquatic Ecology.
This appendix describes the environmental sampling frequencies and analysis procedures by media type.
- 1. CANGE OF SAMPLING PROCEDURES No changes were made to the sampling procedures during 2002.
- 11. DESCRIPTION OF ANALYSIS PROCEDURES Gamma spectroscopy analyses are performed using high purity germanium gamma detectors and Canberra analytical software. Designated sample volumes are transferred to appropriate counting geometries and analyzed by gamma spectroscopy. Perishable samples such as fish and broadleaf vegetation are ground to achieve a homogeneous mixture. Soils and sediments are dried, sifted to remove foreign objects (rocks, clams, glass, etc.) then transferred to appropriate counting geometry. Ten percent of samples receiving gamma analysis are analyzed as duplicate analyses.
Low-level iodine analyses are performed by passing a designated sample aliquot through an ion exchange resin to remove and concentrate any iodine in the aqueous sample (milk). The resin is then dried and transferred to appropriate counting geometry and analyzed by gamma spectroscopy.
Tritium analyses are performed quarterly by using low-level environmental liquid scintillation analysis technique on a Packard 2550 liquid scintillation system. Tritium samples are batch processed with a tritium spike to verify instrument performance and sample preparation technique are acceptable.
Appendix A -Page 2
Gross beta analysis is performed by concentrating a designated aliquot of sample precipitate and analyzing by gas-flow proportional counters. Samples are batch processed with a blank to ensure sample contamination has not occurred.
Ill. CHANGE OF ANALYSIS PROCEDURES No analysis procedures were changed during 2002.
IV. SAMPLING AND ANALYSIS PROCEDURES A.1 AIRBORNE P'ARTICULATE AND RADIOIODINE Airborne particulate and radioiodine samples at each of seven locations were composited continuously by means of continuous air samplers. Air particulates were collected on a particulate filter and radioiodines were collected in a charcoal cartridge situated behind the filter in the sampler. The samplers are designed to operate at a constant flow rate (in order to compensate for any filter loading) and are set to sample approximately 2 cubic feet per minute. Filters and cartridges were collected weekly. A weekly gross beta analysis was performed on each filter and a weekly gamma analysis was performed on each charcoal cartridge. Filters were segregated by location and a quarterly gamma analysis was performed on the filter composite. The filter and charcoal cartridge were analyzed independently. The continuous composite samples were collected from the locations listed below.
Location 120 = Site Boundary (0.5 mi. NNE)
Location 121 = Site Boundary (0.5 mi. NE)
Location 125 = Site Boundary (0.4 mi. SW)
Location 133 = Cornelius, NC (6.2 mi. NE)
Location 134 = East Lincoln Junior High School (8.8 mi. WNW)
Location 192 = Peninsula development (2.8 mi. NNE)
Location 195 = Fishing Access Road (0.2 mi. N)
A.2 DRINKING WATER Biweekly composite samples were collected. A gross beta and gamma analysis was performed on monthly composites. Tritium analysis was performed on the quarterly composites. The composites were collected biweekly from the locations listed below.
Location 101 - North Mecklenburg Water Supply (3.3 mi E)
Location 119 - Mt. Holly Municipal Water Supply (7.4 mi. SSW)
Location 132 - Charlotte Municipal Water Supply (11.2 mi. SSE)
Location 136 = Mooresville Municipal Water Supply (12.7 mi. NNE)
Location 194 - East Lincoln Water Supply (6.7 mi. NNW)
Appendix A - Page 3
A.3 SURFACE WA'ER Biweekly composite samples were collected. A gamma analysis was performed on the monthly composites. Tritium analysis was performed on the quarterly composites sample. The composites were collected biweekly from the locations listed below.
Location 128 = Discharge Canal Bridge (0.4 mi. NE)
Location 131 = Cowans Ford Dam (0.6 mi. WNW)
Location 135 = Plant Marshall Intake Canal (11.9 mi. N)
A.4 MILK Biweekly grab samples were collected at each dairy. A gamma and low-level Iodine-131 analysis was performed on each sample. The biweekly grab samples were collected from the locations listed below.
Location 138 = Henry Cook Dairy - COWS (3.1 mi. ESE)
Location 139 = William Cook Dairy - COWS (2.5 mi. E)
Location 141 = Lynch Dairy - COWS (14.8 mi. WNW)
A.5 1BROADLEAF VEGETATION Monthly samples were collected as available and a gamma analysis was performed on each sample. The samples were collected from the locations listed below.
Location 120 = Site Boundary (0.5 mi. NNE)
Location 125 = Site Boundary (0.4 mi. SW)
Location 134 = East Lincoln Junior High School (8.8 mi. WNW)
Location 193 = Site Boundary (0.2 mi. N)
A.6 FOOD PRODUCTS Samples were collected monthly when available during the harvest season and a gamma analysis was performed on each. The samples were collected at the location listed below.
Location 188 = Garden (2.8 mi N)
A.7 FISH Semiannual samples were collected and a gamma analysis was performed on the edible portions of each sample. Boney fish (i.e. Sunfish) were prepared whole Appendix A -Page 4
minus the head and tail portions. The samples were collected from the locations listed below.
Location 129 = Discharge Canal Entrance to Lake Norman (0.5 mi.ENE)
Location 137 = Pinnacle Access Area (12.0 mi. N)
A.8 SHORELINTE SEDIMENT Semiannual samples were collected and a gamma analysis was performed on each following the drying and removal of rocks and clams. The samples were collected from the locations listed below.
Location 129 = Discharge Canal Entrance to Lake Norman (0.5 mi. ENE)
Location 130 = Highway 73 Bridge Downstream (0.5 mi. SW)
Location 137 = Pinnacle Access Area (12.0 mi. N)
A.9 DIRECT GAMMA RADIATION (TLD)
Thermoluminescent dosimeters (TLD) were collected quarterly at forty-one locations. A gamma exposure rate was determined for each TLD. The TLDs were placed as indicated below.
- An inner ring of 14 TLDs at the site boundary, one in each available meteorological sector. The site boundary locations in the N and NNW sectors are over water; however, two special interest TLD's were placed in these sectors inside the site boundary in March, 1991.
- An outer ring of 16 TLDs, one in each meteorological sector in the 6 to 8 kilometer range.
- The remaining TLDs were placed in special interest areas such as population centers, residential areas, schools, and control locations.
TLD locations are listed in Table 2.1-B.
A.10 ANNUAL LAND USE CENSUS An annual Land Use Census was conducted to identify within a distance of 8 kilometers (5.0 miles) from the station, the nearest location from the site boundary in each of the sixteen meteorological sectors, the following:
- The Nearest Residence
- The Nearest Meat Animal Appendix A - Page 5
- The Nearest Garden greater than 50 square meters or 500 square feet
- The Nearest Milk-giving Animal (cow, goat, etc.)
This census was initiated on June 12, 2002 and completed on June 14, 2002.
Results are shown in Table 3.10.
In the environmental program, the air deposition parameters (D/Q) are used to determine air, broadleaf vegetation and milk sampling locations. McGuire's sectors with the three highest values did not change in 2002.
