1.0 Introduction
This report has been prepared in compliance with 10 CFR 50.36a(a)(2), 10 CFR 72.44(d)(3), Independent Spent Fuel Storage Installation (ISFSI) Technical Specification 5.4.c, and Columbia Generating Station Technical Specification 5.6.2.It includes a summary of the quantities of radioactive liquid and gaseous effluents and solid radwaste released from Columbia Generating Station during calendar year 2008. Effluent data is summarized on a quarterly basis.2.0 Liquid Effluents No planned releases of contaminated liquids from the liquid radwaste processing system were discharged to the Columbia River from Columbia Generating Station during calendar year 2008. The last planned discharge took place in 1998. There were no known releases of liquid effluents to ground or groundwater.
3.0 Gaseous
Effluents The gaseous radwaste effluents from Columbia Generating Station were released from three (3) release points: Main Plant Vent-- mixed mode release Turbine Building -- ground level release Radwaste Building -- ground level release The gaseous source terms from each release point are listed in Tables 3-1, 3-2, and 3-3. The activation gas argon-41 is included in these tables under fission gases to allow a match with the fission and activation gas totals of Table 3-4. Table 3-4 provides a summation of the total activity released, the average release rate, gross alpha radioactivity, and the estimated total error associated with the measurements of radioactivity in the gaseous effluents.
Radioactivity measurements for gaseous effluent releases are performed for fission and activation gases by collecting the samples in a Marinelli beaker and analyzing them using gamma spectroscopy.
Air is analyzed for tritium by collection of water vapor on a desiccant with subsequent distillation and liquid scintillation counting.Particulates and iodines are sampled continuously and the sample media (particulate filters and charcoal cartridges) are analyzed weekly using gamma spectroscopy.
Each quarter a chemical separation process is used to isolate strontium from the composite particulate filters and quantification is accomplished with liquid scintillation detection.
The average energy per disintegration of fission and activation gases is not included in this report as it is not required by Technical Specifications and is not used for gaseous effluent release rate limit calculations.
When a radioisotope is not positively identified at levels greater than the Minimum Detectable Activity (MDA), a value of zero is used for release concentrations and offsite dose assessments.
Table 3-6 contains the Lower Limit of Detection (LLD)values corresponding to the sampling methods and analytical instruments used for each principal radioisotope.
Columbia Generating Station 1 2008 Radioactive Effluent Report Dose calculations were performed for releases using the NRC GASPAR II computer program and parameters as defined in the Offsite Dose Calculation Manual (ODCM). Desert sigmas were not used in gaseous plume growth calculations.
Throughout this report, the term 'dose' is used as defined in NRC Regulatory Guide 1.109-1977.
Quarterly and annual doses to the potentially highest-exposed Member of the Public at and beyond the site boundary were calculated.
In addition, quarterly and annual doses were calculated at actual resident locations identified in the annual land use census. ODCM limits are based on Part 20 and Appendix I to Part 50 of Title 10 of the Code of Federal Regulations.
The threshold for air dose applies to fission and activation gases and is ten (10)millirad for beta and five (5) millirad for gamma quarterly and twenty (20) millirad for beta and ten (10) millirad for gamma annually.
The threshold for organ dose applies to iodine, tritium, and particulates with half-lives greater than eight days and is seven and a half (7.5) millirem quarterly and fifteen (15) millirem annually.
For fission and activation gases the dose rate limits are less than or equal to 500 mrem per year to the whole body and less than or equal to 3000 mrem per year to the skin. For iodines, particulates, and tritium the dose rate limit is less than or equal to 1500 mrem/year to any organ.Dose calculations were also conducted for Members of the Public within the site boundary.
The results are discussed and tabulated in Section 6.0.The Kootenai building is located approximately 0.75 miles from the Reactor building.
Within this building are the Emergency Operations Facility (EOF) and a backup chemistry laboratory.
During 2005, the laboratory liquid release path was physically blocked and the liquid release monitor deactivated.
The release path for the fume hood within the laboratory contains a high-efficiency particulate air (HEPA) filter and was monitored for radioactive releases even though no radiochemical work was routinely performed in this laboratory.
In August of 2008, the fume hood and heating, ventilation, and air conditioning (HVAC) ducting was surveyed and radiological controls removed. No evidence of gaseous or liquid release of licensed radioactive material was noted in 2008 and no further routine effluent release monitoring is planned.It is estimated that approximately 1.76E-03 Curies of tritium were released through unmonitored vents of the heating steam system within and outside the main power block (Turbine, Radwaste, Reactor, and General Services buildings).
Twelve spent fuel storage containers (SFSC) were added to the ISFSI facility in calendar year 2008 (between February and May). A total of twenty seven (27)SFSCs were in place in the ISFSI facility at the end of 2008. The SFSCs are performing as designed; consequently, there are no effluents from this facility.Columbia Generating Station 2 2008 Radioactive Effluent Report In July, a Seal Steam relief valve lifted for 4.7 hours8.101852e-5 days <br />0.00194 hours <br />1.157407e-5 weeks <br />2.6635e-6 months <br /> before being reseated and resulted in 0.0239 Curies of activity being released to the atmosphere.
This amounted to 0.05% of the quarterly releases and 0.02% of the activity released during the year.There were no incidents of effluent monitor inoperability greater than 30 days.Columbia Generating Station 3 2008 Radioactive Effluent Report Columbia Generating Station 3 2008 Radioactive Effluent Report ý Gaseous Effluent Tables Table 3-0 10 CFR Part 50 Appendix I Dose Compliance Report Period: January -- December 2008 I 1st Quarter 12nd Quarter 3rd Quarter I4th Quarter I Year* I Noble Gas Gamma Air Dose (mrad) 1.52E-03 1.41E-03 2.31E-03 2.59E-03 7.46E-03 ODCM Limit 5 5 5 5 10% of Limit 3.04E-02 2.82E-02 4.62E-02 5.18E-02 7.46E-02 Beta Air Dose (mrad) 5.35E-04 4.98E-04 9.64E-04 9.14E-04 2.78E-03 ODCM Limit 10 10 10 10 20% of Limit 5.35E-03 4.98E-03 9.64E-03 9.14E-03 1.39E-02 Iodine-131, Iodine-133, Tritium, and Particulates with half-lives greater than eight days.Organ Dose (mrem) 2.54E-03 2.46E-03 7.02E-03 6.05E-03 1.44E-02 ODCM Limit 7.5 7.5 7.5 7.5 15% of Limit 3.39E-02 3.27E-02 9.36E-02 8.07E-02 9.61E-02* Calculated quarterly doses cannot be directly compared to the annual doses.Each above listed quarterly dose is the highest calculated dose based on a number of variables.
Variables that make comparison difficult include location, meteorological data (quarterly joint frequency distribution (JFD) tables vs. annual JFD tables), receptor age, target organ, and characteristics of the emitted radionuclides.

For fission and activation gases the dose rate limits are less than or equal to 500 mrem/year to the whole body and less than or equal to 3000 mrem/year to the skin. For 1-131, particulates, and tritium the dose rate limit is less than or equal to 1500 mrem/year to any organ.The ODCM dose factors and the highest site boundary dispersion value for each period were used in the calculation.
- Measurement errors are sample-specific.
The values reported represent an approximate overall error.

5.0 Meteorological
Data The meteorological data contained in Tables 5-1 through 5-10 was obtained from the meteorological tower located 2500 feet (762 m) west of Columbia Generating Station. Data was recovered from instruments at the 33-foot (10 meter) and 245-foot (75 meter) levels. The meteorological data is a composite file generated from the automated data recovery systems for the calendar year 2008. Data is archived on the Energy Northwest Local Area Network.Joint data recovery for 2008 was 98.7% from the 33-foot level and 99.1% from the 245-foot level. Redundant wind and temperature sensors are installed at both levels of the meteorological tower. Data from the two systems is mixed to permit maximum data recovery for defined date ranges.The data in Tables 5-1 through 5-8 lists the joint frequency distributions at the 33-foot and 245-foot levels by quarter for 2008. These tables show the total hours at various wind speeds for each sector and stability class. The NRC stability classes A through G and eleven wind speed categories along with the 16 wind direction sectors were used to prepare each joint frequency table. Table 5-9 and 5-10 list the annual joint frequency distributions for those levels for 2008.Wind speed is measured in miles per hour in the following tables and speeds below 1.00 MPH were recorded as calms.Atmospheric factors which affect dispersion and deposition of gaseous effluents as measured on the Hanford Site were snow (30.6 inches total which fell in January, February, and December), total precipitation (5.49 inches), dust or blowing dust (3 days), fog (39 days), and thunderstorms (6 days).

-There were no liquid discharges from the radwaste processing system to the Columbia River during calendar year 2008.Gaseous Effluents
-The NRC GASPAR II computer code was used to calculate doses at and beyond the site boundary using quarterly and annual meteorological data and site-specific variables as required and defined in the ODCM. Table 6-1 shows the highest calculated doses at the site boundary and beyond the site boundary.
Table 6-1 also shows the quarterly and annual dose for the nearest and highest exposed resident identified in the land use census. Table 6-2 lists the annual 50-mile dose using values obtained from the ALARA annual integrated population dose summary (person-rem).
Table 6-2 also provides the annual individual doses associated with each pathway. These values were obtained by dividing the ALARA integrated dose (person-rem) by the estimated year 2000 50-mile population (356,993) and converting to mrem.The highest calculated dose to a child living at locations identified in the most recent land use census was 1.06E-03 mrem to the total body, 1.1 3E-03 mrem to the thyroid, and 1.64E-03 mrem to the skin. This location was at 4.59 miles in the East sector.Periodically, Columbia Generating Station offers public tours of selected locations within the site boundary.
Calculations assumed an eight (8) hour per year exposure to the plume, ground shine, and inhalation pathways.
The organ with the highest dose was the thyroid at 7.96E-04 mrem.During 2008, Members of the Public worked at the Industrial Development area in the E and ESE sectors of the owner controlled area. The maximum dose to these individuals was also calculated assuming adult exposure to the plume, inhalation, and ground deposition pathways.The following table shows dose to Members of the Public from gaseous effluents within the site boundary of Columbia Generating Station for the total indicated hours spent at each location.Total Body Thyroid Highest Other Beta Air Gamma Hours Dose Dose Organ Dose Dose Air Dose Location Spent (mrem) (mrem) (mrem) (mrad) (mrad)Tour Visitors 8.00E+00 5.96E-04 7.96E-04 6.30E-04 9.31 E-06 2.49E-05 WNP-4 Whse.2-4 1.04E+03 2.38E-03 3.02E-03 2.78E-03 2.97E-04 7.96E-04 WNP-1 Bldg 121 2.08E+03 4.26E-03 5.05E-03 5.11E-03 5.27E-04 1.42E-03 There was no measurable direct radiation contribution from Columbia Generating Station to the tour visitors or to the workers at the WNP-1 or WNP-4 industrial areas.During the growing season, Columbia Generating Station conducts a five-mile land use census to determine the locations of nearest residents, gardens, and farm animals out to five miles in each sector. No change to land usage was found.Columbia Generating Station 40 2008 Radioactive Effluent Report The following table provides the results of annual dose calculations for the highest dose age group for each identified land use census location from gaseous effluents.
