1.0 INTRODUCTION
This Annual Radioactive Effluent Release Report is for the R.E. Ginna Nuclear Power Plant and is submitted in accordance with the requirements of Technical Specification Section 5.6.3. The report covers the period from January 1, 2010 through December 31, 2010.
This report includes a summary of the quantities of radioactive gaseous and liquid effluents and solid waste released from the plant presented in the format outlined in Appendix B of Regulatory Guide 1.21, Revision 1, June, 1974.
All gaseous and liquid effluents discharged during this reporting period were in compliance with the limits of the R.E. Ginna Technical Specifications as defined in the Offsite Dose Calculation Manual (ODCM).
2.0 SUPPLEMENTAL INFORMATION 2.1 ReQulatory Limits The ODCM limits applicable to the release of radioactive material in liquid and gaseous effluents are:
2.1.1 Fission and Activation Gases The instantaneous dose rate, as calculated in the ODCM, due to noble gases released in gaseous effluents from the site shall be limited to a release rate which would yield < 500 mrem/yr to the total body and < 3000 mrem/yr to the skin if allowed to continue for a full year.
The air dose, as calculated in the ODCM, due to noble gases released in gaseous effluents from the site shall be limited to the following:
(I) During any calendar quarter to < 5 mrad for gamma radiation and to
< 10 mrad for beta radiation.
(ii) During any calendar year to < 10 mrad for gamma radiation and to
< 20 mrad for beta radiation.
1
2.1.2 Radioiodine, Tritium and Particulates The instantaneous dose rate, as calculated in the ODCM, due to radioactive materials released in gaseous effluents from the site as radioiodines, radioactive materials in particulate form, and radionuclides other than noble gases with half-lives greater than 8 days shall be limited to a release rate which would yield < 1500 mrem/yr to any organ if allowed to continue for a full year.
The dose to an individual, as calculated in the ODCM, from radioiodine, radioactive materials in particulate form and radionuclides other than noble gases with half-lives greater than eight days released with gaseous effluents from the site shall be limited to the following:
(i) During any calendar quarter to < 7.5 mrem to any organ.
(ii) During any calendar year to < 15 mrem to any organ.
2.1.3 Liquid Effluents The release of radioactive liquid effluents shall be such that the concentration in the circulating water discharge does not exceed the limits specified in accordance with Appendix B, Table II, Column 2 and notes thereto of 10CFR20, as explained in Section 1 of the ODCM. For dissolved or entrained noble gases the total activity due to dissolved or entrained noble gases shall not exceed 2E-04 uCi/ml.
The dose or dose commitment to an individual as calculated in the ODCM from radioactive materials in liquid effluents released to unrestricted areas shall be limited:
(i) During any calendar quarter to < 1.5 mrem to the total body and to < 5 mrem to any organ, and (ii) During any calendar year to < 3 mrem to the total body and to < 10 mrem to any organ.
2
2.2 Effluent Concentration Limit (ECL) 2.2.1 For gaseous effluents, effluent concentration limits are not directly used in release rate calculations since the applicable limits are stated in terms of dose rate at the unrestricted area boundary, in accordance with Technical Specification 5.5.4.g.
2.2.2 For liquid effluents, ten times the effluent concentration values specified in 10CFR20, Appendix B, Table II, column 2, are used to calculate release rates and permissible concentrations at the unrestricted area boundary as permitted by Technical Specification 5.5.4.b. A value of 2E-04 uCi/ml is used as the ECL for dissolved and entrained noble gases in liquid effluents.
2.3 Release Rate Limits Based on Average Nuclide Energy The release rate limits for fission and activation gases from the R.E. Ginna Nuclear Power Plant are not based on the average energy of the radionuclide mixture in gaseous effluents; therefore, this value is not applicable. However the 2010 average beta/gamma energy of the radionuclide mixture in fission and activation gases released from Ginna is available for review upon request.
2.4 Measurements and Approximations of Total Radioactivity Gamma spectroscopy was the primary analysis method used to determine the radionuclide composition and concentration of gaseous and liquid effluents. Composite samples were analyzed for Sr-89, Sr-90, and Fe-55 by a contract laboratory. Tritium and alpha analysis were performed using liquid scintillation and gas flow proportional counting respectively.
The total radioactivity in effluent releases was determined from the measured concentration of each radionuclide present and the total volume of effluents released.

SUMMARY
OF GASEOUS RADIOACTIVE EFFLUENTS The quantities of radioactive material released in gaseous effluents are summarized in Tables 1A and lB. Plant Vent and Containment Vent releases are modeled as mixed mode and the Air Ejector is modeled as ground level release.
4.0
SUMMARY
OF LIQUID RADIOACTIVE EFFLUENTS The quantities of radioactive material released in liquid effluents are summarized in tables 2A and 2B.
5.0 SOLID WASTE The quantities of radioactive material released in shipments of solid waste transported from the site during the reporting period are summarized in Table 3.
Principal nuclides were determined by gamma spectroscopy and non-gamma emitters were calculated from scaling factors determined by an independent laboratory from representative samples of that waste type. The majority of Dry Active Waste is processed utilizing an off-site processor who reduces the volume and then sends the waste for burial.
5
6.0 LOWER LIMIT OF DETECTION The required Lower Limit of Detection, (LLD), as defined in the ODCM, was met for all samples used in reporting effluent releases for 2010.
7.0 RADIOLOGICAL IMPACT An assessment of doses to the hypothetical maximally exposed individual member of the public from gaseous and liquid effluents was performed for locations representing the maximum calculated dose in occupied sectors.
Meteorological sectors from WNW through ENE are entirely over Lake Ontario.
In all cases, doses were well below Technical Specification limits as defined in the ODCM. Doses were assessed based upon historical meteorological conditions considering the noble gas exposure, inhalation, ground plane exposure, and ingestion pathways. The ingestion pathways considered were the fruit, vegetable, fish, drinking water, goat's milk, cow's milk and cow meat pathways. Results of this assessment are presented in Tables 4A and 4B.
7.1 Total Dose 40CFR190 limits the total dose to members of the public due to radiation and radioactivity from uranium fuel cycle sources to:
< 25 mrem total body or any organ and;
< 75 mrem thyroid for a calendar year.
Using the maximum exposure and uptake pathways, the maximum liquid pathways, and the maximum direct radiation measurements at the site boundary, yield the following dose summaries to the hypothetical maximally exposed individual member of the public. Dose to any real member of the public should be conservatively bounded by this calculated dose.
10.4 mrem total body (10.4 mrem direct radiation plus 2.4E-2 mrem all other pathways).
1.5E-2 mrem maximum organ dose (Bone).

8.0 METEOROLOGICAL DATA The annual summary of hourly meteorological data collected during 2010 is not included with this report, but can be made available at the R. E. Ginna Nuclear Power Plant.
9.0 LAND USE CENSUS CHANGES There were no major changes in critical receptor location for dose calculations during the reporting period. Minor changes in critical receptor locations and distances came from utilizing updated mapping technologies (hand held global positioning system and Google Earth software). There were no large changes in land use within 5 miles of the plant. Additional new homes are being built at a rate comparable to recent years.
10.0 CHANGES TO THE OFFSITE DOSE CALCULATION MANUAL There were two changes made to the ODCM during 2010. The first change went into effect on August 10, 2010. This change is summarized as follows.
The revisions to table 5-2 of the Offsite Dose Calculation Manual (ODCM) have been proposed to achieve the following:
- 1. Present the data in an easier to read format.
- 2. Provide latitude and longitude coordinates for the air, water, milk, and dosimeter environmental sampling locations. This information, while not provided in the current version of the ODCM, is intended to provide additional detail regarding the environmental sampling program.
- 3. Update the directions and distances for the various environmental sampling locations.
- 4. Add two new dosimeters to Radiological Environmental Monitoring Program (REMP) for Independent Spent Fuel Storage Installation (ISFSI) direct dose monitoring.
The two new dosimeters have been located to monitor direct dose from the ISFSI in the western and south-southwestern meteorological sectors. ISFSI monitoring in the other meteorological sectors can be achieved using existing environmental sampling locations.
None of the existing sampling locations will be relocated as a result of this ODCM change. The compass directions and distances proposed in revision reflect more 7
The two new dosimeters have been located to monitor direct dose from the ISFSI in the western and south-southwestern meteorological sectors. ISFSI monitoring in the other meteorological sectors can be achieved using existing environmental sampling locations.
None of the existing sampling locations will be relocated as a result of this ODCM change. The compass directions and distances proposed in revision reflect more accurate measurements of the same locations, which were obtained using three independent technologies: a hand-held global position system (GPS), Google Earth software application, and mathematical equations The second change went into effect on December 8, 2010. The constituents of this change:
- 1. Definitions Section, page 3. Revising the definition of Dose Equivalent 1-131 from the thyroid dose conversion factors outlined in Regulatory Guide 1.109 to those in ICRP 30, Supplement to Part 1, Pages 192-212, table entitled, "Committed Dose Equivalent in Target Organs or Tissues per Intake of Unit Activity", to align with definitions in the Technical Specifications.
- 2. Section 1.7, Liquid Effluent Dose, page 20, 21, and 22. Revising the average annual liquid dilution factor from 20 to 200. This was change was made as a result of a study performed by Hydroqual, titled "R.E. Ginna Nuclear Power Plant.
Tracer Dilution Study for the Town of Ontario Municipal Drinking Water Intake."
This study was published May 28, 2010. This liquid dilution study was performed as a result of Ontario Water district changing the location of their intake structure.
The completed Hydroqual study is available upon request.
- 3. Section 2.0, Radioactive Gaseous Effluents, page 23. Correction to typographical error regarding 10 times 10CFR20 concentration limits at point of release.
- 4. Section 5.2, Table 5-2, page 79. Revised dosimeter sampling location 64 distance from the centerline of the reactor.
11.0 CHANGES TO THE PROCESS CONTROL PROGRAM There were no changes to the Process Control Program during the reporting period.
12.0 MAJOR CHANGES TO RADWASTE TREATMENT SYSTEMS There were no major changes to the Radwaste Treatment Systems during the reporting period.
8
13.0 INOPERABLE MONITORS None 14.0 CHANGES TO PREVIOUS ANNUAL EFFLUENT OPERATING REPORTS RPA-RW-PCP, "Process Control Program", was revised in 2007 under Procedure Change Request 2007-3427-001. These changes were to update titles, remove references that no longer existed, remove a configuration that is no longer utilized, and to remove the Green is Clean process that is no longer employed. The changes did not change the intent of the Procedure or the PCP.
This change was not included in the 2007 Annual Radioactive Release report as required under Section 6.2 of the ODCM.
RPA-RW-PCP, "Process Control Program", was revised in 2008 under Procedure Change Request 2008-2107-001. This change provided clarification of when Ce-144 may be used to determine transuranics. The change does not change the intent of the PCP. This change was not included in the 2008 Annual Radioactive Release report as required under Section 6.2 of the ODCM.
15.0 GROUNDWATER MONITORING In accordance with R. E. Ginna Nuclear Power Plant's Chemistry procedures, environmental groundwater monitoring wells are sampled quarterly. There are a total of 10 onsite groundwater monitoring wells:
- One located adjacent to the All Volatile Treatment (AVT) Building.
- Three located east of the Screenhouse, screened at 3 depths to include groundwater from top of the water table down to bedrock.
- Two located East of the Containment near the Technical Support Center (TSC)
- One southwest of the Administration Building.
- One to the west of the Screenhouse.
- One to the southeast of the Contaminated Storage Building (CSB).
- One located one-half mile southwest of the plant in the upgradient direction to serve as a control well.
Groundwater samples are analyzed for tritium to a detection limit of 500 pCi/L, and for gamma emitting radionuclides to the environmental LLDs. In 2010, no plant radioactivity was detected in groundwater samples.
Results of the groundwater monitoring well sampling are presented in Table 5.

Table 6 2010 Offsite Dose Due to Carbon-14 R E Ginna Nuclear Power Plant A study of Carbon-14 in effluent releases from Ginna was conducted in 1982 by Charles Kunz of New York State Department of Health, Center for Laboratories and Research.
Results of this study are used as the basis for current Carbon-14 production and releases at Ginna. Using the Carbon-14 releases measured in the Kunz study at 4.3 Curies, adjusted for power uprate from 490 MWe to 580 MWe, and adjusted for increased capacity factor, leads to a conservative estimate of 6.8 Curies released in gaseous effluents in 2010. Kunz further determined the chemical form of the Carbon-14 at Ginna to be approximately 10% C02.
As a cross-check, the EPRI Carbon-14 Source Term Calculator was used to estimate Carbon-14 releases from Ginna, using Ginna specific reactor core data and reactor coolant chemistry to estimate the products of the activation reactions. The resulting estimate of 6.9 Curies per EFPY agrees with the Kunz data.
Dose due to Carbon-14 in gaseous effluents was calculated using the following conditions:
- a. 6.8 Curies of C-14 released to atmosphere in 2010
- b. Release was consistent throughout the year. There was no outage in 2010.
- c. 10% of the C-14 was in the chemical form of C02, which is the only dose contributor. The bulk of C-14 was in the chemical form of methane (CH4) which would exhibit high upward velocity due to its low density relative to air. In addition CH4 does not have an uptake pathway for humans.
- d. Meteorological dispersion factor, (X/Q), at the site boundary to the hypothetical maximally exposed member of the public is 2.43E-07 sec/m3 .
- e. Dose calculations and dose factors are from Regulatory Guide 1.109 methodology.
- f. Pathways considered were inhalation and vegetation ingestion.
- g. Critical receptor is child at the site boundary in the ESE direction.

Dose due to Carbon-14 in liquid effluents was calculated using the following conditions:
- a. The liquid waste processing system at Ginna has not been evaluated for efficiency of removal of Carbon-14. Therefore no removal term was used in estimation of offsite dose.
- b. Average concentration of C-14 in waste water as measured in the Kunz study was adjusted for current operating conditions and was 6.0E-7 uCi/cc.
- c. 1.99E6 liters of liquid waste were released in 2010 with total dilution flow of 1.88E12 liters.
- d. Average diluted concentration of C-14 released was 6.35E-13 uCi/cc.
- e. Liquid effluent dilution factor for potable water pathway is 20.
- f. Liquid effluent dilution factor for fish pathway is 1.
- g. Dose calculations and dose factors are from Regulatory Guide 1.109 methodology.
- h. Critical receptor is teen for both potable water and fish pathways.
