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 5.6.3. It includes a summary of the quantities of radioactive liquid and gaseous effluents and solid radwaste released from Columbia Generating Station during calendar year 2004. Effluent data is summarized on a quarterly basis.

2.0 Liquid Effluents No contaminated liquids from the liquid radwaste processing system were discharged to the Columbia River from Columbia Generating Station during calendar year 2004.

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-4 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 using particulate filters and charcoal cartridges. Both are analyzed using gamma spectroscopy. 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.

Noble gas activities are commonly below detection limits in the building effluent ducts.

When no radioactive noble gas was detected in an effluent duct, a value of zero was used for release and dose calculations.

Dose calculations were performed for releases using the NRC GASPAR II computer program and parameters as defined in the Offsite Dose Calculation Manual (ODCM).

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 locations identified in the annual land use census. ODCM limits are based on Columbia Generating Station I 2004 Radioactive Effluent Report

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. The radiochemical hood within the backup chemistry lab contains a HEPA filter and is monitored for radioactive releases when in operation. All liquids are routed to a sump that is monitored for radioactive material prior to release by a lift pump to the sewage treatment facility. No evidence of gaseous or liquid release of licensed radioactive material was noted in 2004.

It is estimated that approximately 6.45E-03 Curies of tritium were released through unmonitored vents associated with the heating steam system.

Ten spent fuel storage containers (SFSC) were placed in the ISFSI facility in 2004 resulting in a total of fifteen SFSCs. The SFSCs are performing as designed; consequently, there were no effluents from this facility.

There were no abnormal releases of gaseous effluent during this reporting period.

Effluent Monitor Issues:

The Turbine Building gaseous effluent noble gas low range monitor was declared inoperable on April 9, 2004, because heat tracing was not able to maintain process stream temperatures above the design specification. The engineering staff identified problems with the design bases temperature setpoint, process piping insulation, and the heat trace temperature indicator. A work request was initiated on April 26"' and on May 8th the requested work was completed. Additional work was initiated to resolve conflicts in design documentation and to revise procedures. The sample rack was returned to operable status on May 17, 2004. (Condition Reports 2-04-01334 and 2-04-02075)

The Turbine building gaseous effluent isokinetic control sample rack was declared inoperable on November 18, 2004, due to a mismatch of the effluent linear velocity between the HVAC duct and the sample line resulting in anisokinetic flow. An attempt to clean the sample line failed to resolve the issue. Further troubleshooting determined that a three-way valve in the rack was leaking at the diaphragm and that Station Generating Station 2 2004 Radioactive Effluent Report Columbia Generating 2 2004 Radioactive Effuent Report

the blower was degraded. Repairs were successful and the monitor was declared operable on January 5, 2005. (Condition Report 2-04-04168)

The Reactor building effluent release low range noble gas monitor was declared inoperable on December 1, 2004, due to a failed radiological calibration. It was returned to operable status on January 10, 2005. It could not be restored within 30 days because of an inability to initially determine the cause of the failure. Early investigations suggested problems with the log rate meter and the source positioning tube. Eventually, the gas calibration factor was revised and the detector declared operable.

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 JED tables), receptor age, target organ, and characteristics of the emitted radionuclides.

t No noble gas activity was detected above the minimum detectable level during the first quarter.

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 all periods the dose rate to the whole body was higher than that to the skin and therefore, the Percent of ODCM limit is calculated for the whole body limit. For I-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 and release point flow rates and estimates of plateout factors.

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 m) and 245-foot (75 m) levels. The meteorological data is a composite file from the automated data recovery systems for the calendar year 2004. Data is archived on the Energy Northwest Local Area Network.

Joint data recovery for 2004 was 97.5% from both the 245-foot level and the 33-foot level.

Redundant wind and temperature sensors are installed at both levels of the meteorological tower. These redundant sensors are labeled System 'A' and System 'B'. The entire year's joint frequency distribution was calculated using the System 'A' data.

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 2004. 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 categories along with the 16 wind 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 2004.

Calibrations performed in 2004 required no corrections be applied to the raw data. Data below 1.00 MPH is recorded as a calm.

6.0 DOSE ASSESSMENT -- IMPACT ON MAN Liquid Effluents - There were no liquid discharges from the radwaste processing system to the Columbia River during calendar year 2004.

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 2.02E-03 mrem to the total body, 2.02E-03 mrem to the thyroid, and 2.23E-03 mrem to the skin. This location was at 4.01 miles in the ENE sector.

Members of the public were not exposed at the Columbia Generating Station Visitor Center because this facility remained closed throughout the year.

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. The dose assessment results for this group are tabulated below.

During 2004, members of the public worked at the WNP-1 industrial area. The maximum dose to these individuals was also calculated assuming 2040 hours0.0236 days 0.567 hours 0.00337 weeks 7.7622e-4 months per year exposure to the plume, inhalation, and ground deposition pathways. The maximum doses received by the adult age group (full-time employees) are shown below.

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.

There was no measurable direct radiation contribution from Columbia Generating Station to the workers at the WNP-1 Industrial Area.

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. In 2004, no residents were identified in the SE sector contrary to previous years. A garden was identified in the ENE sector, but the garden contained no broad leaf vegetables. Based on the ODCM and regulatory guidance (Branch Technical Position, December 21, 1979, Environmental Monitoring for Direct Radiation), the garden was not assumed in dose calculations.

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.

For environmental TLD stations at or beyond the site boundary where preoperational (background) data was acquired, no increase in ambient exposure was observed in 2004 from the preoperational values. Within the site boundary, the environmental TLD station with the highest direct radiation reading was located 0.1 mi from Columbia Generating Station in the NNW sector between the ISFSI facility and the Turbine Generator building. The annual dose at this location from direct radiation only was 2.66E+02 mrem after subtracting background (Station 9A at 30 miles WSW). Contributions to this direct radiation dose are from the Turbine building and spent fuel storage containers at the ISFSI facility.
