SUMMARY

S 0*This Annual Radiological Environmental Operating Report describes the McGuire Nuclear Station Radiological Environmental Monitoring Program (REMP), and the 0program results for the calendar year 2012.Included are the identification of sampling locations, descriptions of environmental sampling and analysis procedures, comparisons of present environmental radioactivity levels and pre-operational environmental data, comparisons of doses calculated from 0environmental measurements and effluent data, analysis of trends in environmental

radiological data as potentially affected by station operations, and a summary of environmental radiological sampling results. Quality assurance practices, sampling deviations, unavailable samples, and program changes are also discussed.

0Sampling activities were conducted as prescribed by Selected Licensee Commitments (SLC's). Required analyses were performed and detection capabilities were met for all collected samples as required by SLC's. Eleven-hundred thirty samples were analyzed comprising 1,585 test results in order to compile data for the 2012 report. Based on the 0annual land use census, the current number of sampling sites for McGuire Nuclear*Station is sufficient.

0Concentrations observed in the environment in 2012 for station related radionuclides

were generally within the ranges of concentrations observed in the past. Inspection of Sdata showed that radioactivity concentrations in surface water, drinking water, shoreline*sediment and fish are higher than the activities reported for samples collected prior to the operation of the station. Measured concentrations were not higher than expected, and all positively identified measurements attributable to station operation were within limits as*specified in SLC's.0 Additionally, environmental radiological monitoring data is consistent with effluents introduced into the environment by plant operations.

The total body dose estimated to Sthe maximum exposed member of the public as calculated by environmental sampling*data, excluding TLD results, was 8.35E-2 mrem for 2012. Background radiation dose in*the United States is approximately 620 mrem per year (approximately half from naturally occurring sources such as radon and half from man-made sources such as medical 0processes) (reference 6.14). It is therefore concluded that station operations has had no*significant radiological impact on the health and safety of the public or the environment.

2.0 INTRODUCTION

2.1 SITE DESCRIPTION AND SAMPLE LOCATIONS*McGuire Nuclear Station (MNS) is located geographically near the center of a highly industrialized region of the Carolinas.

The land is predominantly rural non-farm with a small amount of land being used for farming. The McGuire site is in northwestern Mecklenburg County, North Carolina, 17 miles north-northwest of Charlotte, North Carolina.

The site is*bounded to the west by the Catawba River channel and to the north by 32,510 acre Lake 0Norman. Lake Norman is impounded by Duke Energy Corporation's Cowans Ford Dam*Hydroelectric Station. The tailwater of Cowans Ford Dam is the upper limit of Mountain Island Reservoir.

Mountain Island Dam is located 15 miles downstream from the site. Lookout Shoals Hydroelectric Station is at the upper reaches of Lake Norman. Marshall Steam Station is located 0on the western shore of Lake Norman, approximately 16 miles upstream from the site (reference

6.3).0MNS consists of two pressurized water reactors.

Each reactor unit is essentially a mirror image*of the other joined by an auxiliary building housing both separate and common equipment.

Each*unit was designed to produce approximately 1200 gross Megawatts of electricity.

Unit 1*achieved criticality August 8, 1981 and Unit 2 on May 8, 1983.*Figures 2.1-1 and 2.1-2 are maps depicting the Thermoluminescent Dosimeter (TLD) monitoring 0locations and the sampling locations.

The location numbers shown on these maps correspond to*those listed in Tables 2.1-A and 2.1-B. Figure 2.1-1 comprises all sample locations within 0.5 mile radius of MNS. Figure 2.1-2 comprises all sample locations within a ten mile radius of MNS.0* 2.2 SCOPE AND REQUIREMENTS OF THE REMP An environmental monitoring program has been in effect at McGuire Nuclear Station since 1977, 0four years prior to operation of Unit 1 in 1981. The preoperational program provides data on the*existing environmental radioactivity levels for the site and vicinity which may be used to determine whether increases in environmental levels are attributable to the station. The operational program provides surveillance and backup support of detailed effluent monitoring which is necessary to evaluate the significance, if any, of the contributions to the existing 0environmental radioactivity levels that result from station operation.

0 This monitoring program is based on NRC guidance as reflected in the Selected Licensee Commitments Manual, with regard to sample media, sampling locations, sampling frequency, 0and analytical sensitivity requirements.

Indicator and control locations were established for 0comparison purposes to distinguish radioactivity of station origin from natural or other "man-made" environmental radioactivity.

The environmental monitoring program also verifies projected and anticipated radionuclide concentrations in the environment and related exposures from releases of radionuclides from McGuire Nuclear Station. This program satisfies the 0 0 O ~Section 2 -Pagel1 0 0 0 0 requirements of Section IV.B.2 of Appendix I to 1OCFR50 and provides surveillance of all appropriate critical exposure pathways to man and protects vital interests of the company, public, and state and federal agencies concerned with the environment.

Reporting levels for 0 radioactivity found in environmental samples are listed in Table 2.2-A. Table 2.2-B lists the REMP analysis and frequency schedule.The Annual Land Use Census, required by Selected Licensee Commitments, is performed to 0 ensure that changes in the use of areas at or beyond the site boundary are identified and that 0 modifications to the Radiological Environmental Monitoring Program are made if required by changes in land use. This census satisfies the requirements of Section IV.B.3 of Appendix I to lOCFR50. Results are shown in Table 3.10.Participation in an interlaboratory comparison program as required by Selected Licensee Commitments provides for independent checks on the precision and accuracy of measurements of radioactive material in REMP sample matrices.

Such checks are performed as part of the quality assurance program for environmental monitoring in order to demonstrate that the results 0 are valid for the purposes of Section IV.B.2 of Appendix I to 10CFR50. A summary of the results obtained as part of this comparison program are in Section 5 of this annual report.2.3 STATISTICAL AND CALCULATIONAL METHODOLOGY 0 2.3.1 ESTIMATION OF THE MEAN VALUE 0 0 There was one (1) basic statistical calculation performed on the raw data resulting from the environmental sample analysis program. The calculation involved the determination of the mean value for the indicator and the control samples for each sample medium. The mean is a widely used statistic.

This value was used in the reduction of the data 0 generated by the sampling and analysis of the various media in the Radiological Environmental Monitoring Program. "Net activity (or concentration)" is the activity (or concentration) determined to be present in the sample. No "Minimum Detectable Activity", "Lower Limit of Detection", "Less Than Level", or negative activities or 0 concentrations are included in the calculation of the mean. The following equation was used to estimate the mean (reference 6.8): N 0 I Xi X N Where: 0 x = estimate of the mean,=individual sample, O N = total number of samples with a net activity (or concentration), 0 Xi = net activity (or concentration) for sample i. 0 0 0 0 Section 2 -Page 2 0 0 0 0 0* 2.3.2 LOWER LEVEL OF DETECTION AND MINIMUM DETECTABLE

ACTIVITY*The Lower Level of Detection (LLD) and Minimum Detectable Activity (MDA) are used*throughout the Environmental Monitoring Program.0LLD -The LLD, as defined in the Selected Licensee Commitments Manual is the smallest concentration of radioactive material in a sample that will yield a net count,*above the system background, that will be detected with 95% probability with only 5%probability of falsely concluding that a blank observation represents a "real" signal. The LLD is an a priori lower limit of detection.

The actual LLD is dependent upon the standard deviation of the background counting rate, the counting efficiency, the sample size (mass or volume), the radiochemical yield, and the radioactive decay of the sample between sample collection and counting.

The "required" LLD's for each sample medium*and selected radionuclides are given in the Selected Licensee Commitments and are listed in Table 2.2-C.0*MDA -The MDA is the net counting rate (sample after subtraction of background) that must be surpassed before a sample is considered to contain a scientifically measurable amount of a radioactive material exceeding background amounts. The MDA is Scalculated using a sample background and may be thought of as an "actual" LLD for a 5particular sample measurement.

2.3.3 TREND IDENTIFICATION 0One of the purposes of an environmental monitoring program is to determine if there is a buildup of radionuclides in the environment due to the operation of the nuclear station.Visual inspection of tabular or graphical presentations of data (including preoperational) is used to determine if a trend exists. A decrease in a particular radionuclide's 0concentration in an environmental medium does not indicate that reactor operations are removing radioactivity from the environment but that reactor operations are not adding that radionuclide to the environment in quantities exceeding the preoperational level and that the normal removal processes (radioactive decay, deposition, resuspension, etc.) are 0influencing the concentration.

0 Substantial increases or decreases in the amount of a particular radionuclide's release from the nuclear plant will greatly affect the resulting environmental levels; therefore, a 0knowledge of the release of a radionuclide from the nuclear plant is necessary to completely interpret the trends, or lack of trends, determined from the environmental data. Some factors that may affect environmental levels of radionuclides include prevailing weather conditions (periods of drought, solar cycles or heavier than normal 0precipitation), construction in or around either the nuclear plant or the sampling location, 0and addition or deletion of other sources of radioactive materials (such as the Chernobyl accident).

Some of these factors may be obvious while others are sometimes unknown.Therefore, how trends are identified will include some judgment by plant personnel.

3.0 INTERPRETATION OF RESULTS S* Review of 2012 REMP analysis results was performed to detect and identify changes in 0environmental levels as a result of station operation.

The radionuclides with Selected Licensee*Commitments reporting levels that indicate consistent detectable activity have been historically trended from preoperation to present. Analyses from 1977 -1978 have been excluded since these results were much higher than the other preoperational years due to outside influences such as 0weapons testing. The preoperational analyses from 1981 were combined with the operational analyses from the latter part of 1981 and averaged to give one concentration for each*radionuclide for that year.0The highest annual mean concentration of applicable Selected Licensee Commitments 0radionuclides from the indicator locations for each media type was used for trending purposes.*Trending was performed by comparing annual mean concentrations to historical results. Factors evaluated include the frequency of detection and the concentration in terms of the percent of the*radionuclide's SLC reporting level (Table 2.2-A). All maximum percent of reporting level*values attributable to MNS plant operation were well below the 100% action level. The highest*value attributable to MNS plant operations during 2012 was 4.22% for drinking water tritium at the North Mecklenburg Water Treatment Facility (Location 101). Only Selected Licensee Commitments radionuclides were detected in 2012.*Changes in sample location, analytical technique, and presentation of results must be considered when reviewing for trends. Calculation of the annual mean concentrations has been performed differently over the history of the REMP. During 1979-1986, all net results (sample minus background) positive and negative, were included in the calculation of the mean. Only positive 0net activity results were used to calculate the mean for the other years. All negative values were replaced with a zero for calculational and graphical purposes to properly represent environmental conditions.

A change in gamma spectroscopy analysis systems in 1987 ended a period when many measurements yielded detectable low-level activity for both indicator and control location*samples.

It is possible that the method the previous system used to estimate net activity may 5have been vulnerable to false-positive results.0 This section includes tables and graphs containing the highest annual mean concentrations of any effluent related radionuclide detected since the change in analysis systems in 1987. Any zero 0concentrations used in tables or graphs represent activity measurements less than detectable levels. Only the specific radionuclides that represent the highest dose contributors or demonstrate consistent detectable activity are shown graphically.

Data presented in Sections 3.1 through 3.9 support the conclusion that there was no significant increase in radioactivity in the environment around McGuire Nuclear Station due to station*operations in 2012. Similarly, there was no significant increase in ambient background radiation levels in the surrounding areas. The 2012 land use census data, shown in Section 3.10, indicates 0that no program changes are required as a result of the census.0 0* Section 3 -Pagel1 0 0 3.1 AIRBORNE RADIOIODINE AND PARTICULATES In 2012, 364 particulate and radioiodine samples were analyzed, 312 at six indicator locations and 52 at the control location.

Particulate samples were analyzed weekly for gamma and gross beta. Radioiodine samples received a weekly gamma analysis.Gross beta analyses indicated 2.1OE-2 pCi/m 3 at the location with the highest annual mean and 2.08E-2 pCi/m 3 at the control location.

Detectable gamma emitting particulate activity (Co-58)was last observed in environmental air particulate samples in 2004 (reference 6.15).No detectable 1-131 activity in any environmental air radioiodine samples was found in 2012.K-40 and Be-7 that occur naturally were routinely detected in charcoal cartridges collected during the year.Figure 3.1 shows gross beta highest annual mean indicator and control location concentrations since 1985. There is no reporting level for gross beta. Table 3.1-A shows indicator and control location highest annual means for Cs-137 and gross beta.Table 3.1-B gives indicator location highest annual means and control means since 1979 for 1-131. Preoperational and ten year averages are also shown. No 1-131 activity due to MNS plant operation has been detected since 1989. Since no activity was detected in 2012, no reporting levels were approached.

Fifty-two samples were from the four indicator locations and 13 from the control location.

Tritium (H-3) analyses were performed on 20 composite samples, 16 at indicator locations and four at the control location.No detectable gamma activity was found in drinking water samples in 2012 and has not been detected since 1987. Gross beta analyses indicated 1.74 pCi/1 at the location with the highest annual mean and 1.66 pCi/l at the control location.

Tritium was detected in fourteen of the 16 indicator composite samples taken in 2012 with the highest annual mean resulting in only 3.98% of the reporting level. Tritium was not detected in any of the four control location samples. The dose for consumption of water was less than one mrem per year, historically and for 2012; therefore low-level iodine analysis is not required.Figure 3.2 shows tritium highest annual mean indicator and control location concentrations with comparisons to 20% of the reporting level. Table 3.2 gives indicator location highest annual means and control means since 1979 for tritium and gross beta. There is no reporting level for gross beta.Drinking water Location 101 was added to the sampling program in 1999. Figure 3.2 shows an increase beginning in that year. There was an increase in tritium releases in 2006 due to silica removal from the spent fuel pools. This resulted in additional water volume being released from the plant. An extreme drought during the second half of 2007 and much of 2008 affecting the Catawba River Basin resulted in less dilution volume available in Lake Norman.Figure 3.2 pCi/liter 5000 4500 4000 3500 3000 2500 2000 1500 1000 500 Concentration of Tritium in Drinking Water 0 49 8 a 18 a991 19 1997 20 0 0 2003 200 2 00 20 1979 1982 1985 1988 1991 1994 1997 2000 2003 2006 2009 2012 I -U- Indicator Location--- Control Location-20% Re porting Level Section 3 -Page 5 Table 3.2 Mean Concentrations of Radionuclides in Drinking Water Gross Beta (pCi/I) Tritium (pCi/1)YEAR Indicator Control Indicator Control Location Location Location Location 1979 2.40E0 2.03E0 1.65E2 1.50E2 1980 2.34E0 1.87E0 1.63E2 2.05E2 1981 2.79E0 2.41E0 1.88E2 1.78E2 1982 2.62E0 2.43E0 2.43E2 1.45E2 1983 1.80E0 1.87E0 2.65E2 1.45E2 1984 2.78E0 1.81E0 5.77E2 2.45E2 1985 1.88E0 1.90E0 5.93E2 4.00E2 1986 2.13E0 2.15E0 1.14E3 4.37E2 1987 2.30E0 2.OOEO 1.35E3 7.75E2 1988 2.00E0 2.OOEO 9.92E2 7.1 1E2 1989 2.80E0 2.70E0 5.62E2 0.00E0 1990 3.70E0 4.30E0 7.32E2 6.11E2 1991 2.40E0 2.50E0 5.22E2 0.OOEO 1992 2.OOEO 1.70E0 6.73E2 0.OOEO 1993 2.80E0 2.0E0 0.00E0 0.00E0 1994 2.47E0 2.90E0 0.00E0 0.00E0 1995 4.20E0 3.30E0 3.58E2 0.00E0 1996 2.75E0 2.11 E0 3.60E2 0.00E0 1997 2.70E0 2.24E0 2.90E2 0.OOEO 1998 2.75E0 2.33E0 2.68E2 0.OOEO 1999 2.48E0 2.17E0 5.49E2 0.00E0 2000 2.66E0 1.99E0 5.04E2 0.OOEO 2001 2.48E0 2.19E0 6.98E2 0.OOEO 2002 2.47E0 2.08E0 5.64E2 0.00E0 2003 1.81E0 1.52E0 3.51E2 0.00E0 2004 1.68E0 1.29E0 4.61E2 O.OOEO 2005 1.74E0 1.30E0 7.35E2 0.00E0 2006 1.75E0 1.80E0 1.46E3 0.OOEO 2007 1.81 EO 1.76E0 1.48E3 O.OOEO 2008 2.40E0 1.87E0 1.52E3 2.26E2 2009 1.90E0 1.81E0 1.03E3 1.86E2 2010 1.85E0 1.74E0 7.20E2 0.OOEO 2011 1.77E0 1.75E0 9.97E2 0.OOEO 2012 1.74E0 1.66E0 7.95E2 0.OOEO 0.OOEO = no detectable measurements 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 Section 3 -Page 6 0 0 0 0 0 0 0 3.3 SURFACE WATER In 2012, 39 surface water samples were analyzed for gamma emitting radionuclides, 26 at the two indicator locations and 13 at the control location.

A transit background for environmental TLDs is determined based on ANSI N545. The highest annual mean exposure for an indicator location was 106 milliroentgen.

The annual mean exposure for the control location was 92 milliroentgen.

Figure 3.9-1 and Table 3.9-A show TLD inner ring (site boundary), outer ring (4-5 miles), and control location annual averages in milliroentgen per year. Preoperational data and ten year rolling averages are also given. As shown in the graph, inner and outer ring averages historically compare closely, with control data somewhat higher. Inner and outer ring averages comprise a number of data points with the control average representing only one location.The control location has historically been higher than indicator locations.

This is most likely an artifact of the underlying geologic structures at the control location.

TLDs located greater than 5 miles from the plant demonstrate a wide range of background radiation levels. The control location is 15.5 miles WNW, well beyond the influence of the plant.The calculated total body dose from gaseous effluents for 2012 was 2.88E-1 millirem, which is 0.45% of the average inner ring TLD values. Therefore, it can be concluded that discharges from the plant had very little impact on the measured TLD values.0 A TLD intercomparison program is conducted as part of the quality assurance program. Results of this program are included in section 5.10.Figures 3.9-2 and 3.9-3 show the TLD mean for each inner and outer ring TLD location from 1987 through 2011.3.9.2 ISFSI 0 The McGuire ISFSI is located inside the protected area on the west side of the plant approximately 244 meters from plant centerline.

The ISFSI protected area fence on the north side is approximately 60 meters from the owner control fence atop the berm adjacent to Lake Norman and just west of the intake structure.

At a distance of 425 meters the ISFSI is closest to the Exclusion Area Boundary (EAB) on the west side along the Catawba River. The nearest resident to the ISFSI is just over a kilometer away in the east sector with the next closest resident at 1.1 kilometers in the WNW sector.The ISFSI is situated in a slight depression in relationship to other structures inside the protected area. The ISFSI direct radiation to the north is shielded by the berm on the south boundary of Lake Norman. The EAB to the west of ISFSI is shielded from direct radiation by the drop in elevation from 754' at the ISFSI to the river bank below the 0 Section 3 -Page 18 5 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 Cowan's Ford Dam. These features lessen the dose impact to the public accessing the EAB west of ISFSI and the Lake Norman shoreline inside the EAB north of ISFSI.There are no effluent releases from the fuel canisters stored inside the shielded casks to the environment.

Doses measured by environmental TLDs show little or no change since the current TLD system was implemented.

Table 3.10 summarizes census results. A map indicating identified locations is shown in Figure 3.10.During the 2012 census, no new residences (nearer to the plant), irrigated gardens (superior to existing gardens) or milk locations were identified.

The nearest residence is located in the East sector at 0.48 miles. No environmental program changes were required as a result of the 2012 land use census.Table 3.10 McGuire 2012 Land Use Census Results Sector Distance Sector Distance (Miles) (Miles)Nearest Residence 2.53 Nearest Residence 1.45 N Nearest Garden (irrigated) 2.79 S Nearest Garden 3.14 Nearest Milk Animal -Nearest Milk Animal -Nearest Residence 1.23 Nearest Residence 2.56 NNE Nearest Garden 4.27 SSW Nearest Garden 2.94 Nearest Milk Animal -Nearest Milk Animal -Nearest Residence 1.21 Nearest Residence 1.85 NE Nearest Garden 1.80 sw Nearest Garden 1.98 Nearest Milk Animal -Nearest Milk Animal -Nearest Residence 0.57 Nearest Residence 1.01 ENE Nearest Garden 1.98 WSW Nearest Garden 1.33 Nearest Milk Animal -Nearest Milk Animal -Nearest Residence 0.48 Nearest Residence 1.15 E Nearest Garden 2.16 w Nearest Garden 1.23 Nearest Milk Animal -Nearest Milk Animal -Nearest Residence 0.65 Nearest Residence 0.88 ESE Nearest Garden 1.20 WNW Nearest Garden 2.06 Nearest Milk Animal -Nearest Milk Animal -Nearest Residence 0.67 Nearest Residence 0.95 SE Nearest Garden 1.18 NW Nearest Garden 1.68 Nearest Milk Animal -Nearest Milk Animal -Nearest Residence 1.06 Nearest Residence 1.48 SSE Nearest Garden 1.06 NNW Nearest Garden (irrigated) 1.69 Nearest Milk Animal -Nearest Milk Animal -"-" indicates no occurrences within the 5 mile radius Section 3 -Page 23 Figure 3.10 Section 3 -Page 24 0 S* 4.0 EVALUATION OF DOSE 0* 4.1 DOSE FROM ENVIRONMENTAL MEASUREMENTS Annual doses to maximum exposed individuals were estimated based on measured*concentrations of radionuclides in 2012 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 0background concentration at the corresponding control location was subtracted.

0Regulatory 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, milk or*vegetation sample types because no radionuclides attributable to MNS station operations were detected.

Naturally occurring K-40 and Be-7 were detected in some samples but were not included in any REMP-based dose estimates.

Dose estimates 0are not reported for surface water because sampled surface water is not considered to be a potable drinking water source although surface water tritium concentrations are used in calculating doses from fish. Exposure estimates based upon REMP TLD results are discussed in Section 3.9.S 0The maximum environmental organ dose estimate for any single sample type (excluding TLD results) collected during 2012 was 8.23E-2 mrem to the child total body, liver, thyroid, kidney, lung, and GI-LLI from the consumption of drinking water.0* 4.2 ESTIMATED DOSE FROM RELEASES Throughout the year, dose estimates were calculated based on actual 2012 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. These doses are shown in Table 4.1-A along with the corresponding REMP-based dose estimates.

Summaries of RETDAS dose calculations are reported in the Annual Radioactive Effluent Release Report 0 (reference 6.6).0 O Section 4 -Page 1 0 0 The effluent-based liquid release doses are summations of the dose contributions 0 from the drinking water, fish, and shoreline pathways.

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 0 0 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.Additionally, in 2010 McGuire began reporting estimated dose from effluent Carbon 14 (C-14). This change came about with the issuing of Regulatory Guide 1.21, Revision 2, Measuring, Evaluating and Reporting Radioactive Material in Liquid and Gaseous Effluents and Solid Waste. A description of this change is found in the 2010 Annual Radiological Effluent Release Report. C-14 is not measured in the environment and therefore, environmental and effluent doses from C-14 cannot be compared directly.In calculations based on liquid release pathways, drinking water consumption was the predominant dose pathway based on environmental and effluent data. The maximum total organ dose based on 2012 environmental sample results was 8.35E-2 mrem to the child total body. The maximum total organ dose of 1.22E-1 mrem for liquid effluent-based estimates was to the child GI-LLI.o In calculations based on gaseous release pathways, vegetation was the predominant dose pathway for effluent samples. The maximum organ dose for gaseous effluent estimates was 8.75E-1 mrem to the child bone. No radioactivity was detected from gaseous pathways in environmental samples; therefore, there is no calculated dose.The doses calculated do not exceed 40CFR190 or 1OCFR50 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.S S 0 S S Section 4 -Page 2 S S TABLE 4.1-A Page 1 of 2 MCGUIRE NUCLEAR STATION 2012 ENVIRONMENTAL AND EFFLUENT DOSE COMPARISON S 0 0 S 0 0 0 0 0 0 0 0 0 0 0 0 LIQUID RELEASE PATHWAY Environmental or Critical Critical Maximum Dose (3)Organ Effluent Data Age (1) Pathway (2) Location (mrem)Skin Environmental Teen Shoreline Sediment 130 (0.52 mi SW) 1.87E-04 Skin Effluent Teen Shoreline Sediment Discharge Pt. 4.35E-04 Bone Environmental Teen -0.OOE+00 Bone Effluent Teen Shoreline Sediment Discharge Pt. 6.OOE-04 Liver Environmental Child Drinking Water 101 (3.31 mi E) 8.34E-02 Liver Effluent Child Drinking Water 3.31 mi E 1.21E-01 T.

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 0 Records, and Fisheries and Aquatic Ecology.S This appendix describes the environmental sampling frequencies and analysis procedures by media type.I. CHANGE OF SAMPLING PROCEDURES Indicator location 104 (Crops) added as a replacement for indicator location 188 (Crops), which was removed from the program (reference 6.16) since the garden owner discontinued the garden.H. 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.Low-level iodine analyses are performed by passing a designated sample aliquot through a pre-weighed amount of ion exchange resin to remove and concentrate any iodine in the aqueous sample (milk). The resin is then dried, mixed thoroughly, and a net resin weight determined before being 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 or Perkin-Elmer 2900TR liquid scintillation system. Tritium samples are distilled and batch processed with a tritium spike and blank to verify instrument performance and sample preparation technique are acceptable.

SAMPLING AND ANALYSIS PROCEDURES A.1 AIRBORNE PARTICULATE 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 positioned 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 separate weekly gamma analysis was performed on each charcoal cartridge and air particulate.

A weekly gross beta analysis was performed on each filter. The continuous composite samples were collected from the locations listed below.Location 102 Location 103 Location 120 Location 121 Location 125 Location 133 Location 195 Amity Church Road (9.89 mi.

A gamma exposure rate was determined for each TLD. TLD locations are listed in Table 2.1-B. 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.S* 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.

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:

S* The Nearest Residence S* The Nearest Garden greater than 50 square meters or 500 square feet* The Nearest Milk-giving Animal (cow, goat, etc.)*The census was conducted during the growing season on 5/22/2012.

Results are*shown in Table 3.10. No changes were made to the sampling procedures during 2012*as a result of the 2012 census.*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 2012.Appendix A -Page 5 V. GLOBAL POSITIONING SYSTEM (GPS) ANALYSIS The McGuire site centerline used for GPS measurements was referenced from the McGuire Nuclear Station Updated Final Safety Analysis Report (UFSAR), section 2.1.1, Site Location.

Waypoint coordinates used for MNS GPS measurements were latitude 35°-25'-59"N and longitude 80'-56'-55"W.

Maps and tables were generated using North American Datum (NAD) 27. Data normally reflect accuracy to within 2 to 5 meters from point of measurement.

GPS field measurements were taken as close as possible to the item of interest.

Distances for the locations are displayed using three significant figures.Appendix A -Page 6 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 APPENDIX B RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM
