II. DETAILED INFORMATION (CONT'D)
D. Measurements and Approximations of Total Activity The following discussion details the methods used to measure and approximate the total activity for the following:
Tables 10 and 2C sampling frequencies and Lower Limit of Detection requirements for the analysis of gaseous and liquid effluent streams, respectively.
Values in the attached tables as zero do not necessarily imply that the radionuclides were not A zero indicates that the radionuclide was not present at levels greater than the sensitivity requirements shown in Tables 1D and 2C. For some radionuclides, lower detection levels than required may be readily achievable; when a radionuclide is measured below its stated detection limits, it is reported.
- 1. For Fission and Activation Gases The following noble gases are considered in evaluating gaseous airborne discharges:
Periodic grab samples from Station effluent streams are analyzed by gamma spectral analysis utilizing high-resolution germanium detectors. (See Table 1D for sampling and analytical requirements.) Isotopic values thus obtained are used for dose release rate calculations due to effluent releases as given in Section II.A.! of this report. The radionuclides that are detected are used in this computation. When no radionuclides are detected, a historical mixture is used. During the period between grab samples, the amount of radioactivity released is based on the effluent monitor readings. Monitors are assigned a calibration factor based upon the last isotopic analysis, using the following relationship:
where C j = isotopic calibration factor for isotope i OJ = concentration of isotope i in the grab sample in /-1Ci/ml.
m = net monitor reading associated with the effluent stream (determined at the time of grab sampling).
Page 8 Revision 1
II. DETAILED INFORlVIATION (CONT'D)
These calibration factors, along with the hourly effluent monitor values and flow rates, are entered into the laboratory computer where the release rates for individual radionuclides are calculated and stored. Ifno activity is detected in the grab sample, the calibration factor defaults to a historical mixture of Kr-88, Xe- 133, Xe- 135m, Xe-l and Xe- I38.
- 2. For Particulates and Radioiodines At a minimum, the following radioiodines and radioactive materials in particulate form to be considered are:
Mo-99 Cs-134 Cs-137 Ce-141 Ce-144 1- 131 1-133
- 3. For Continuous Releases Continuous sampling is performed on the continuous release points when releasing (i.e.:
Offgas/Radwaste Building, Containment Building, Fuel Handling Area, Turbine Building, and Turbine Building Occasional Release Point). Particulate material is collected by filtration. Radioiodines are collected by adsorption onto a charcoal filter. Periodically these filters are removed and analyzed by gamma spectral analysis utilizing high-resolution germanium detectors to identify and quantify radioactive materials collected.
Particulate filters are then analyzed for gross alpha and Strontium-89/90 as required.
Gross alpha is analyzed using a gas flow proportional technique. Strontium-89/90 values are obtained by chemical separation and subsequent counting analysis using gas flow proportional techniques. Tritium concentrations are determined using distillation and liquid scintillation techniques. During major operational occurrences, the frequency of sampling is increased to satisfy the requirements of footnote "c" of Table 10, "Radioactive Gaseous Waste Sampling and Analysis," (GGNS ODCM Appendix A, Table 6.11.4-1). Strontium analysis is performed by a qualified contract laboratory.
Carbon-14 (C-14) activity of 11.30 Curies released per year in gaseous form was obtained by estimation using EPRI spreadsheet B\VR Source Term Calculation (MAL-1)_rl and the information in NEAD-NS-ll-0060-Revl-EC42519 and adjusted by 236 full power production days. Carbon-14 curies are reported in Tables lA and lC of this report and based on a constant release rate throughout the year.
- 4. For Batch Releases: Gases Gaseous batch releases are not normally performed at GGNS.
Page 9 Revision 1
II. DETAILED INFORMATION (CONT'D)
- 5. For Batch Releases: Liquid Effluents At a minimum, the radionuclides listed below are considered when evaluating liquid effluents:
[-13 I Cs-I34 Cs-137 Ce-141 Ce-I44 Representative pre-release grab samples are obtained and analyzed as required by Table 2C. Isotopic analyses are performed by gamma spectral analysis utilizing high-resolution germanium detectors. Aliquots of each pre-released sample, proportional to the waste volume released, are composited in accordance with the requirements of Table 2C.
Strontium-89/90 and Iron-55 values are obtained by individual chemical separations.
Strontium-89/90 is analyzed using gas flow proportional techniques. Iron-55 is analyzed using liquid scintillation techniques. Gross alpha is analyzed using a gas flow proportional technique. Tritium is distilled and then analyzed using liquid scintillation techniques. Dissolved gases are determined employing grab sampling techniques and analyzed by gamma spectral analysis utilizing high-resolution germanium detectors. Iron and Strontium analyses are performed by a qualified contract laboratory.

Measurement errors include uncertainty associated with instrument calibration and the preparation and counting of low-activity samples. Counting errors are based on measurements of blank samples. For gennanium detectors, the least-readily-detectable radioisotope is used to detennine the counting error. Calibration errors are calculated by summing the errors associated with the calibration of a particular instrument with a radioactive source.
The total error is calculated by taking the square root of the sum of the squares of the individual errors.

The predominant stability class was class "0" approximately 29.6% of the time. wind speed during the reporting period was approximately 4.2 miles per hour at the 33 foot elevation.
The annual meteorological data (Hourly Average Data or Joint Frequency Distribution) will be maintained on site in a file that shall be provided to the NRC upon request.
J. Radioactive Effluent Monitoring Instrumentation Operability Liquid radwaste effluent radiation monitor was inoperable for> 14 days per Limiting Condition for Operation 1-0TS-12-0030. This was documented in Condition Report GGN-2012-06059.
ODeM action 6.3.9 8.3 has a completion time of 14 days to restore channel to operable, which was exceeded at 12:46 on April 2012.. Exceeding this completion time requires entry into Condition 0 with required action 0.1 to immediately suspend Liquid Radwaste releases and action 0.2 to immediately initiate action to explain in the next Annual Radioactive Effluent Release Report why the inoperability was not corrected in a timely manner. Restoration of this equipment was delayed by Refueling Outage 18 critical path activities. In addition, a retest delay occurred and was documented in Condition Report GGN-2012-06007.
K. Annual Sewage Disposal Summary There were 2 sewage sludge shipments in 2012 consisting of 8 8-25 boxes that were shipped to EnergySolutions for Green is Clean.

III. RADIATION DOSE
SUMMARY
Indicated below is the annual summary of offsite doses attributable to GGNS during 2012. Inspection of the values indicates that GGNS releases were within the IOCFR50, Appendix I, design objectives.
Since there are no other fuel cycle facilities within 8 km of GGNS, 40CFR 190 limits were also met during this period.
A. Water-Related Exposure Pathways The values calculated in this section utilize the information provided in Tables 2A and 2B of this report and the calculation methodology of the ODCM.
Liquid Effluents Total body dose and critical organ doses are computed for the maximum exposed individual.
The maximum dose contribution from liquid effluents is considered to occur in the adult age group via consumption of fish.

Airborne-Related Exposure Pathways The values presented in this section utilize information provided in Tables 1A and 1C of this report and the calculation methodology of the ODCM. Carbon-I4 doses were calculated using Electric Power Research Institute, EPRI, methodology and calculation software which was validated on site using Regulatory Guide 1.109. Dose and dose rates are computed for locations at the site boundary or at unrestricted areas within the site boundary. Because members of the public may, on occasion, be found within the site boundary, two fishing lakes, the recreational vehicle laydown area, and the GGNS Energy Services Center locations were also evaluated.
Consideration of site boundary locations as well as unrestricted areas within and beyond the site boundary provides assurance that offsite doses will not be substantially underestimated while attempting to provide an accurate dose calculation.
Doses for a Member of the Public are computed based on 2012 meteorological data and on the most recent land use census, with the most limiting location used.
During normal operations, the dispersion and deposition factors used for dose calculations are from five-year historical annual average meteorological data.
Page 13 Revision 1
III. RADIATION DOSE SU~IMARY (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 2012 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. This dose is documented in the following table as two separate entries. The first organ dose entry excludes C-14 while the second entry includes organ dose from tritium, radioiodines, particulates, and C-14.
Individual total body and skin dose rates from exposure to a semi-infinite cloud of noble gas are computed for a location in the southwest sector at a distance of 1368 meters (0.85 miles) from the plant. This location corresponds to the highest annual average atmospheric dispersion factor for a location at or within the site boundary based on 2012 meteorological data.
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 represent the maximum possible dose rate received by members of the public.
Air doses from gaseous effluents were calculated for this report using dispersion parameters from the 2012 meteorological data. The highest dispersion factor for an unrestricted area was in the southwest sector at the site boundary, 1368 meters (0.85 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 2012 as net exposure normalized to 92 days.

III. RADIATION DOSE SUl\1lVIARY (CONT'D)
Carbon-l 4 Carbon-14 (C-14) is a naturally occurring isotope of carbon. Nuclear weapons testing in the 1950s and 1960s significantly increased the amount of C-14 in the atmosphere. Carbon-14 is also produced in commercial nuclear reactors, but the amounts produced are much less than those produced naturally or from weapons testing. In recent years, the analytical methods for determining C-14 have improved. Coincidentally the radioactive effluents from commercial nuclear power plants have also decreased to the point that C-14 has emerged as a principal radionuclide in gaseous effluents.
The only significant dose pathway to a member of the public from C-14 release is through consumption of vegetation. Vegetation incorporates C-14 in form of carbon dioxide (C0 2) during photosynthesis so doses are calculated based on the CO 2 fraction of the carbon released in gaseous form. A CO 2 fraction of95% is used based on EPRI Technical Report 1021106, "Estimation ofCarbon-14 in Nuclear Power Plant Gaseous Effluents". The highest atmospheric dispersion factor for an actual garden based on the land use census was used to determine dose from C-14. Carbon-l 4 is dispersed as a gas (C0 2) to the garden location, where it is then incorporated into plant material.
Carbon-14 dose is calculated to a MEMBER OF THE PUBLIC for the most age restrictive group (Child) and organ (bone) at the garden location. This doses is then added to dose for the same organ from tritium, iodine, and particulates. This organ dose is recorded and compared to the limit in the following table.

ATTACHlVlENT I Nuclear Energy Institute, NEI, Groundwater Protection Initiative Sample Results JANUARY - DECElVlBER 2012 GPI Ground \Yater samples are collected from onsite dewatering wells, DW; monitoring wells, lVIW; observation wells, OW; and sump wells, S\Y. Samples were analyzed for tritium and selected samples were analyzed for gamma and/or hard to detect (HTD) isotopes (Gross Alpha, Iron-55, Nickel-63, Strontium-89 and Strontium-90).
Analyses are to the Lower Level of Detection (LLD) values for the GGNS Radiological Environmental lVlonitoring Program.
No dose to the public is attributed to ground water since wells with results above lVlDA are bounded by wells which are <MDA. Tritium, gamma and HTD results are shown in the table below.
All results were less than Reporting Levels of GGNS-ODCM table 6.12.1-2.
