-7 II.DETAILED INFORMATION (CONT'D)D.Measurements and Approximations of Total Activity The following discussion details the methods used to measure and approximatethetotal activity for the following:

Fission and Activation Gases Radioiodines Particulates Liquid Effluents Tables ID and 2C give sampling frequencies and Lower Limit of Detection requirements for the analysis of gaseous and liquid effluent streams, respectively.

Values in the attached tables given as zero do not necessarily imply that the radionuclides were not present.A zero indicates that the radionuclide was not present at levels greater than the sensitivity requirements shown in Tables1D 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 At a miniumum, the following noble gases are considered in evaluating gaseous airborne discharges:

.Kr-87 Kr-88 Xe-133 Xe-133mXe-135Xe-138 Periodic grab samples from Station effluent streams are analyzed by gamma spectral analysis utilizing high-resolution germanium detectors.(See Table ID 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.l 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 Vi=concentration of isotope i in the grab sample in 11 Ci/ml.m=net monitor reading associated with the effluent stream (determined at the time of grab sampling).

en v-tec/A RERRO1-8 II.DETAILED INFORMATION (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.If no activity is detected in the grab sample, the calibration factor defaults to a historical mixture of Kr-88, Xe-133, Xe-135m, Xe-135, and Xe-138.2.For Particulates and Radioiodines At a minimum, the following radioiodines and radioactive materials in particulate form to be considered are: Zn-65 Mo-99 Mn-54 Cs-134 Fe-59 Cs-137 Co-58 Ce-141 Co-60 Ce-144 Sr-89 1-131 Sr-90 1-133 Other detected radionuclides with half lives greater than 8 days.3.For Continuous Releases Continuous sample collection 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.

Radio-iodines 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.

89/90 values are obtained by chemical separation and subsequent counting analysis using gas flow proportional techniques.

Tritium samples are collected on molecular sieve and 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 ID,"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)curies are reported in Tables lA and lC of this report and based on a constant release rate throughout the year.Activity of 9.5 Curies released per year in gaseous form is used based on: GGNS Final Safety Analysis Report Table 11.3-9 which utilizes BWR-Gale Code and says,"C-14 Released via Main Condenser Offgas System=9.5 Ci/Yr." This is assumed to be the total released in gaseous form based on International Atomic Energy Agency Technical Reports Series No.421, Management of Waste Containing Tritium and Carbon-14 which says,"The following systems have been considered to be release pathways for gaseous 14C from a BWR:"..."The condenser steam jet air ejector is expected to be the most significant release point (>99%of total 14C release)." 4.For Batch Releases: Gases Gaseous batch releases are not normally performed at GGNS.en v-tec/A RERRO1-9 II.DETAILED INFORMATION (CONT'D)5.For Batch Releases: Liquid Effluents At a minimum, the radionuclides listed below are considered when evaluating liquid effluents:

H-3 Mn-54 Fe-55 Co-58 Co-60 Fe-59 Zn-65 Sr-89 Sr-90 Mo-99 1-131 Cs-134 Cs-137 Ce-141 Ce-144 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-8,9/90 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 concentrations are determined using distillation and 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.

SUMMARY

Indicated below is the annual summary of offsite doses attributable to GGNS during 2013.Inspection of the values indicates that GGNS releases were within the 10CFR50, Appendix I, design objectives.

Since there are no other fuel cycle facilities within 8 kIn of GGNS, 40CFR190 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.2013 Ld Effl D lCUl uent ose mrem 1 st Qtr 2nd Qtr 3rd Qtr 4th Qtr TOTAL Bone 3.31E-02 8.96E-03 3.77E-02 4.25E-03 7.98E-02 Liver 5.89E-02 2.35E-02 6.25E-02 1.20E-02 1.49E-OI Thyroid 2.12E-03 2.21E-03 1.70E-03 1.10E-03 6.72E-03 Kidney 2.63E-02 1.32E-02 2.35E-02 7.38E-03 6.62E-02 Lung 6.90E-03 3.00E-03 7.66E-03 1.37E-03 1.80E-02 GI-LLI 2.24E-02 1.89E-02 1.04E-02 8.71E-03 5.50E-02 Applicable Limit 5 5 5 5 10 Percent of Limit 1.18E+00 4.70E-Ol 1.25E+00 2.40E-Ol 1.49E+00 Whole Body 3.49E-02 1.24E-02 4.20E-02 6.47E-03 9.71E-02 Applicable Limit 1.5 1.5 1.5 1.5 3 Percent of Limit 2.33E+00 8.27E-Ol 2.80E+00 4.31E-Ol 3.24E+00 B.Airborne-Related Exposure Pathways The values presented in this section utilize information provided in Tables1A and1C of this report and the calculation methodology of the ODCM.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.

env-tec/ARERR01-13 III.RADIATION DOSE

SUMMARY

(CONT'D)Doses for a Member of the Public (critical receptor)are computed based on 2013 meteorological data and 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.Organ Dose The maximum organ dose to a MEMBER OF THE PUBLIC from radioiodines, tritium, and particulates was calculated for this report using the most recent land use census and dispersion and deposition parameters from 2013 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.

Doses due to Carbon-14 release were calculated using Electric Power Research Institute, EPRI, methodology and calculation software which was validated on site using Regulatory Guide 1.109.The doses are documented in the following table as two separate entries.The first organ dose entry excludes C-14whilethe second entry includes organ dose from tritium, radioiodines, particulates, and C-14..A verage 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 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 2013 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 Dose from Gamma and Beta Emissions Air doses from gaseous effluents were calculated for this report using dispersion parametersfromthe 2013 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 controllocationsfrom average doses measured by TLD badges located near the site boundary.GGNS reported measured doses in 2013 as net exposure normalized to 92 days.env-tec/ARERR01-14 III.RADIATION DOSE

SUMMARY

(CONT'D)Carbon-14 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 the form of carbon dioxide (C0 2)during photosynthesis, therefore doses are calculated based on the CO 2 fraction of the carbon.released in gaseous form.A CO 2 fraction of 95%is used based on EPRI Technical Report 1021106,"Estimation of Carbon-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-14 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 C-14 dose is then added to dose from tritium, iodine, and particulates for the same age group and organ.This organ dose is recorded and compared to the limit in the following table.2013 Airborne Effluent Dose (mrem)1 st Qtr 2nd Qtr 3rd Qtr 4th Qtr TOTAL Iodine, Tritium&Particulates (excluding Carbon-14)
