1.0 Introduction
This report has been prepared in compliance with Parts 50 and 72 of Title 10 of the Code of Federal Regulations (CFR), specifically 10 CFR 50.36a(a)(2) and 10 CFR 72.44(d)(3), Independent Spent Fuel Storage Installation (ISFSI) Technical Specification 5.4.c, and Columbia Generating Station (CGS) 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 2011. Effluent data is summarized on a quarterly basis.Throughout this report, units of activity and dose are as defined in 10 CFR 20.1004, 20.1005, and Nuclear Regulatory Commission (NRC) Regulatory Guide 1.109-1977.The United States National Council on Radiation Protection published Report #160 in 2009 which can serve to put radiation dose into perspective for the reader of this report. It was determined that the average yearly dose to a person living in the United States is 620 mrem from all sources. Of this, -50% is attributed to natural sources (radiation from gaseous radon, cosmic or space radiation, natural radioactive material in the ground, and natural radioactive materials in our bodies).About 48% is attributed to diagnostic and therapeutic medical exposure.
Radiation dose from nuclear power was grouped into a category comprising
<0.1% of the total.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 2011. The last planned discharge took place in 1998.In 2011, there were no known leaks to the environment of radioactive liquids.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 -mixed mode 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.
Columbia Generating Station I 2011 Radioactive Effluent Report 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.
Dose calculations were performed for releases using the NRC XOQDOQ and GASPAR II computer programs and parameter values as described in the Offsite Dose Calculation Manual (ODCM) with some exceptions.
A Self-Assessment identified opportunities for improving the accuracy of values presented in ODCM Table 3-13 which describe the characteristics of gaseous effluent release points.The following table (3.0-A) shows values used as input to XOQDOQ which differ from those presented in the ODCM table.Columbia Generating Station 2 2011 Radioactive Effluent Report Table 3.0-A: Deviations from Input Parameters in ODCM Table 3-13 Reactor Radwaste I Bldg Bldg ITurbine Bldg Vent Velocity (m/s)Value in ODCM 1 10.9 3.4 1 19.5 Value used in XOQDOQ '10.9 0 21.0 XOQDOQ requires the vertical exit velocity.
Release from the Radwaste bldg is horizontal.
Release from the Turbine bldg is vertical and was recalculated.
Vent Inside Diameter (m)IValue in ODCM I 2.1 3.8 3.3 Value used in XOQDOQ 2.1 0 3.0 NUREG/CR-2919 recommends a value of 0 for ground mode release points (Radwaste bldg). The Turbine bldg value was recalculated.
Average annual heat flow from release point [Heat Emission Rate] (cal/sec)IValue in ODCM I 1.06E+06 2.90E+06 9.10E+05 Value used in XOQDOQ 1.59E+05 1.04E+05 8.02E+05 The heat emission rates were recalculated The XOQDOQ program was also provided with updated terrain elevations out to a 25-mile radius of Columbia Generating Station in each sector. The above changes allowed better modeling of plume vertical momentum and buoyancy resulting in more accurate dispersion and deposition values from those presented in ODCM Tables 3-3, 3-10, and 3-11. The ODCM is in the process of revision to reflect the above changes.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 10 CFR 20 and Appendix I to 10 CFR 50.The threshold for air dose applies to fission and activation gases and is ten (10)mrad for beta and five (5) mrad for gamma quarterly and twenty (20) mrad for beta and ten (10) mrad 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) mrem quarterly and fifteen (15) mrem 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.It is estimated that approximately 9.53E-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).
No additional spent fuel storage containers (SFSC) were added to the ISFSI facility in calendar year 2011. A total of twenty seven (27) SFSCs were in place in the ISFSI facility at the end of 2011. There were twelve SFSCs loaded in 2008 that were considered Operable (i.e. no measurable leakage) but nonconforming based Columbia Generating Station 3 2011 Radioactive Effluent Report on the vendor failing to leak test the canisters during fabrication.
This was communicated to the NRC via Energy Northwest letter, G02-10-157 (ADAMS Accession Number ML 103070299), submitted October 27, 2010. Energy Northwest received a response from the NRC dated July 7, 2011, G12-11-106 (ADAMS Accession Number ML 111880244), which indicated continued use of the affected canisters is acceptable with no further action required.
Since the contents of the affected canisters and the canisters themselves meet all other storage requirements, Energy Northwest considers the nonconforming condition resolved.All SFSCs are Operable and, as such, are performing as designed.
Based on compliance with ISFSI Technical Specification
3.1.1 during
2011, there are no effluents from this facility.Incidents of effluent monitor inoperability greater than 30 days: During 2011, the turbine building gaseous effluent flow rate monitor (ODCM RFO 6.1.2 Function 4 d) failed during ODCM surveillance activity on May 30, 2011. The monitor was out of service greater than 30 days because the flow transmitter was no longer available and did not have a recommended replacement from the original equipment manufacturer.
A decision was made to repair the item using an experienced third party shop. Despite two attempts to repair the component the repair was unsuccessful and the unit was determined to be irreparable.
A design change was approved and completed which took the original pneumatic signal, converted it to an electrical signal, and then converted it back into a pneumatic signal that could be transmitted to the Square Root Converter.
This involved adding two new signal units and a power supply. The monitor was returned to service on December 23, 2011. The total time out of service was 207 days.The turbine service water system gross radioactivity monitor (ODCM RFO 6.1.1 Function 3) was declared non-functional on August 10, 2011, to validate calculations of the ODCM alarm setpoint established at the time of the monitor installation in August of 2006. The initial alarm setpoint was based on estimates of instrument performance.
It was returned to service on September 13, 2011, (34 days) following a statistical analysis of the observed background and a review of instrument error estimates.
The reactor building elevated discharge radiation monitor (ODCM RFO 6.1.2 Function 3 a) was taken out of service on March 15, 2011, to replace a malfunctioning regulating transformer.
Although the new transformer was energized on April 1, 2011, the discharge radiation monitor was left out of service during the refueling outage. On June 26, 2011, the detectors were returned to service but within hours, power from the regulating transformer was lost. The transformer was placed in manual and the loads were energized on July 26, 2011.The monitor was finally declared functional on August 31, 2011. The total out of service time was 169 days.Columbia Generating Station 4 2011 Radioactive Effluent Report Gaseous Effluent Tables Table 3-0 10 CFR Part 50 Appendix I Dose Compliance Report Period: January -- December 2011 I 1st Quarter 12nd Quarter 13rd Quarter I 4th QuarterI Year* I Noble Gas Gamma Air Dose (mrad) 2.19E-02 7.73E-04 O.OOE+00 3.12E-03 2.08E-02 ODCM Limit 5 5 5 5 10% of Limit 4.38E-01 1.55E-02 O.OOE+00 6.24E-02 2.08E-01 Beta Air Dose (mrad) 7.74E-03 2.74E-04 0.OOE+00 1 .1OE-03 7.35E-03 ODCM Limit 10 10 10 10 20% of Limit 7.74E-02 2.74E-03 O.OOE+00 1.1OE-02 3.68E-02 Iodine-131, Iodine-133, Tritium, and Particulates with half-lives greater than eight days.Organ Dose (mrem) 2.37E-02 1.25E-03 1.13E-03 3.43E-03 2.40E-02 ODCM Limit 7.5 7.5 7.5 7.5 15% of Limit 3.16E-01 1.67E-02 1.50E-02 4.58E-02 1.60E-01* 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.
In the above chart, all dose is calculated to a hypothetical person at the site boundary.Columbia Generating Station 5 2011 Radioactive Effluent Report Table 3-1 Main Plant Vent Releases Fission Gases and lodines Report Period: January -- December 2011 1st 2nd 3rd 4th Quarter Quarter Quarter Quarter Year Nuclides Released (Ci) (Ci) (Ci) (Ci) (Ci)A.

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. The major contributors of this error are measurements associated with sample volume, release point flow rates, and estimates of plateout factors.Columbia Generating Station 12 2011 Radioactive Effluent Report Table 3-5 Gaseous Purges and Vents Report Period: January -- December 2011 Total Maximum Mean Type Purge Vent Number 3.OOE+00 2.20E+0 1 Total Time (hr.)4.97E+01 3.20E+01 Maximum Time (hr.)4.39E+O 1 5.92E+00 Minimum Time (hr.)2.37E+00 4.3 3E-0l Mean Time (hr.)1.66E+01 1.45 E+00 Columbia Generating Station is a continuous release plant.

5.0 Meteorological
Data The meteorological data contained in Tables 5-1 through 5-11 was obtained from a meteorological tower located 762 meters (2500 feet) west of Columbia Generating Station. Data was recovered from two sets of redundant instruments on the tower at the 10 meter (33-foot) and 75 meter (245- foot) levels. The meteorological data is a composite file generated from the automated data recovery systems for the calendar year 2011. Data is archived on the Energy Northwest Local Area Network.Meteorological data recovery for 2011 was 91.3% from both the 33-foot and the 245-foot levels. 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 provide joint frequency distributions (JFD) at the 10-meter and 75-meter levels by quarter for 2011. 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. Tables 5-9 and 5-10 provide the annual joint frequency distributions at the specified heights for 2011. Table 5-11 provides a joint frequency distribution from the 10 meter wind instruments during daylight hours of the growing season. The threshold value for daylight was chosen at solar irradiance of greater than 5 watts/m2 .This JFD table was used for Carbon-14 (14C) dose estimates from ingestion pathways.Wind speed is measured in miles per hour in the tables and speeds below 1.0 MPH were recorded as calms.There are a number of atmospheric factors which affect dispersivity but which are not modeled in the CGS estimates of dispersion and deposition.
Those conditions which were measured or documented at the Hanford Meteorological Station during 2011 were snow (3.1 inches total which fell in January, November and December), total precipitation (4.45 inches), dust or blowing dust (2 day), fog (40 days), and thunderstorms (11 days).Rainfall as recorded at the Columbia Generating Station meteorological tower was 2.96 inches.Columbia Generating Station 21 2011 Radioactive Effluent Report Columbia Generating Station 21 2011 Radioactive Effluent Report Joint Frequency Distribution Tables for 2011 Table 5-1 1st Quarter Average, 33 Ft Above Ground Level (AGL)Hours at each wind speed and direction during time period Elevation:

-There were no liquid discharges from the radwaste processing system to the Columbia River during calendar year 2011.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 provides the population collective dose within a 50-mile radius. These values were obtained from the ALARA annual integrated population dose summary (in person-rem) of the GASPAR computer code output file. Table 6-2 also provides the annual average 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.During the growing season, Columbia Generating Station conducts a five-mile land use census to determine the locations of nearest residents, gardens, and milk animals or other livestock out to five miles in each sector. The 2011 Land Use Census did not identify broad leaf vegetable gardens or milk animals within the 5-mile radius. Cattle, goats, and horses were observed within 5-miles. Although it was not determined if the nearest residents were actually consuming meat from these animals, the beef and goat meat pathways were assumed in the sectors where these animals were observed.
The NRC computer code GASPAR was used for dose estimates.
IAEA Technical Series Report 4721 was used to derive Stable Element Transfer ratios to convert the GASPAR beef meat dose output to dose from goat meat. As substantial commercial fruit orchards and corn crops were observed in all eastern sectors with residents, it was assumed that these crops were being consumed by the residents.
The GASPAR code consumption rates were revised to reflect these differences.
An estimate of Carbon-14 (1 4 C) releases in units of Curies (Ci) was made based on thermal power generation in units of gigawatts-thermal (GWth).1 4 C Production Rate 5.1 +/- 0.6 Ci/GWth -yr Rated Thermal Power 3.486 GWth CGS Production Rate 17.8 +/- 2.1 Ci/yr at rated power GWth-hrs Ci of 1 4 C Ci of 1 4 CO 2 1st Quarter 7488.9 4.4 4.2 2nd Quarter 95.0 0.056 0.053 3rd Quarter 87.9 0.051 0.048 4th Quarter 7460.2 4.3 4.1 Total Year 2011 151 32.0 8.8 8.4 Growing Season 1205.8 1.4 1.3 Handbook Of Parameter Values For The Prediction Of Radionuclide Transfer In Terrestrial And Freshwater Environments, IAEA Technical Series Report 472, 2010 Columbia Generating Station 44 2011 Radioactive Effluent Report The 1 4 C production rate was estimated in Electric Power Research Institute (EPRI)Technical Report 1021106 which also estimated that 95% of 14C production is released as 14CO2 As 14C in the form of 14C02 is a non-depositing, gaseous effluent, it enters the food chain through plant photosynthesis.
Since Columbia Generating Station is a continuous release plant, normally, offsite dose is based on meteorological data throughout the year. For 14C dose analysis, however, a Joint Frequency Distribution (JFD) table of atmospheric data was developed based on daylight hours (solar irradiance
> 5 watts per square meter) during the growing season of both vegetables and pasture grass for beef (April 15th through October 15th). The JFD table was used as input into the NRC XOQDOQ computer code from which dispersion estimates were obtained.
This method provides a more accurate method of determining the average air concentration of 14002 during times of photosynthesis.
Both inhalation and ingestion pathways contribute to dose from 14C. The inhalation 14 ~14 1 dose estimate assumes a full year 14C inhalation of both OH 4 and 14CO2. The ingestion pathway assumes 14C ingestion from 14002 incorporation into vegetation and meat during daylight hours of the growing season.The highest dose calculated was for the resident at 4.24 miles in the ESE sector due to higher dispersion and deposition in that sector. The annual dose to the potential maximally exposed individual (child living at resident location 4.24 miles ESE) from gaseous releases of 14C is 5.34E-03 mrem to the critical organ (bone)and 1.06E-03 mrem to the total body. The available dose pathways at this location were inhalation and the ingestion of garden produce (fruits, grains, and non-leafy vegetables).
Nearby sectors with beef and goat meat ingestion pathways had lower total body and bone dose due to lower dispersion values. Dose from 14C is only included in Table 6.0-C of this section.For all other gaseous releases, the highest calculated dose to a child living at locations identified in the most recent land use census was 1.90E-03 mrem to the total body, 2.23E-03 mrem to the thyroid, and 2.88E-03 mrem to the skin. This location was at 4.24 miles in the East South 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 skin at 5.41 E-04 mrem.Columbia Generating Station 45 2011 Radioactive Effluent Report During 2011, Members of the Public worked within the owner controlled area at the Industrial Development area in the E and ESE sectors and at the DOE 618-11 burial site in the W and WNW sectors. The maximum dose from gaseous effluents to these individuals was also estimated assuming adult exposure to the plume, inhalation, and ground deposition pathways.The following table (6.0-A) shows estimated dose to Members of the Public from gaseous effluents and direct radiation exposure within the site boundary of Columbia Generating Station for the total indicated hours spent at each location.Table 6.0-A; Estimated Dose to Members of the Public within the Site Boundary Total Body Thyroid Highest Other Beta Air Gamma Direct Hours Dose Dose Organ Dose Dose Air Dose Radiation Location Spent (mrem) (mrem) (mrem) (mrad) (mrad) (mrem)Tour Visitors 8.OOE+00 3.45E-04 3.65E-04 5.41E-04 1.72E-04 4.86E-04 1.35E-02 Firing Range 8.OOE+00 2.93E-06 2.95E-06 4.53E-O6 1.36E-06 3.84E-06 O.OOE+00 618-11 DOE Site 2.OOE+03 1.89E-03 1.93E-03 2.89E-03 8.56E-04 2.42E-03 6.19E+00 WNP-4Whse.2-4 2.60E+03 3.83E-03 3.88E-03 5.85E-03 1.70E-03 4.83E-03 O.OOE+00 WNP-1 Bldg 121 2.60E+03 1.11E-02 1.11E-02 1.71E-02 5.10E-03 1.45E-02 n.00E+OO Table 6.0-B provides the results of annual dose calculations for the highest dose age group for each identified land use census location from gaseous effluents.

For each time period, the dose estimate uses the radionuclide mix and release rate for that period along with an estimate of the dispersion in air and deposition on ground and vegetation calculated by the NRC computer code XOQDOQ using actual meteorological conditions during the respective quarters.
The dose estimate of the NRC computer code GASPAR uses, as base methodology, NRC Regulatory Guide 1.109 (1974) which includes the prospective dose component arising from retention in the body beyond the period of environmental exposure.Columbia Generating Station 50 2011 Radioactive Effluent Report Table 6-2 50-Mile Population Dose from Gaseous Effluents A. 50-mile population collective dose Exposure Total Body Max.

7.0 REVISIONS
TO THE ODCM One revision was made to the ODCM which involved Requirement For Operability
6.1.2 Radioactive
Gaseous Effluent Monitoring Instrumentation.
The previous revision only required one channel of the Offgas Post Treatment Radiation Monitors to be Operable and had Required Compensatory Actions to take if that one channel was Inoperable (Condition C). The Required Compensatory Measure was to take a noble gas grab sample every eight hours. The revision created Required Compensatory Measures to take if even one of the two available channels is not available.
The revised Required Compensatory Measure ensures that the plant design described in the Final Safety Analysis Report Section 11.5.2.2.1.2 is maintained by verification that Inoperable channels are placed in a trip condition or by implementing administrative controls to prevent exceeding effluent limits. The frequency of noble gas grab samples for the Required Compensatory Measure was extended from once every eight hours to once every twelve hours consistent with the guidance of NUREG-1 302.8.0 REVISIONS TO THE PROCESS CONTROL PROGRAM (PCP)The Process Control Program, SWP-RMP-02 was changed in November 2011 to update the descriptions of the processing systems used to prepare spent resin for disposal.
These changes were needed because the casks that were available to ship "Type B" resin, the processed RWCU resin for disposal, from our previous system lost their certification.
The frequency of the scaling factors, 10 CFR 61 required analysis was changed from annual to biennial, from every year to every two years to coincide with the Columbia Generating Station fuel cycle. The waste classification branch technical position (BTP) provided acceptable approaches for the development of facility and waste stream specific scaling factors. The guidance calls for reasonable efforts to be conducted for waste characterization.
An acceptable sample frequency associated with these reasonable efforts was stated in the BTP as annually for Class B and Class C waste and every two years for Class A wastes. There is also some latitude to lengthen these sample frequencies based on plant conditions remaining stable. In practice, plant operations are typically conducted to minimize perturbations during the fuel cycle making changes in waste characteristics minimal during that time.Columbia Generating Station 52 2011 Radioactive Effluent Report 9.0 NEW OR DELETED LOCATIONS FOR DOSE ASSESSMENTS AND/OR ENVIRONMENTAL MONITORING LOCATIONS 9.1 The 2011 Five-Mile Land Use Census showed no new pathways of exposure.
