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 2005. 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 2005.

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 scinrtillation 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.

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 GASPAR II computer program and parameters as defined in the C)ffsite 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 ColubiaGeneatig Sttio 1

005 adiactie Efluet Rpor Columbia Generating Station I

2005 Radioactive Effluent Report

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 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 release path for the radiochemical hood within the backup laboratory contains a HEPA filter and is monitored for radioactive releases even though no radiochemical work is routinely performed in this laboratory. During 2005, the laboratory liquid release path was physically blocked and the liquid release monitor deactivated. No evidence of gaseous or liquid release of licensed radioactive material was noted in 2005.

It is estimated that approximately 2.965E-3 Curies of tritium were released through unmonitored vents associated with the heating steam system.

A total of fifteen loaded spent fuel storage containers (SFSC) were in place in the ISFSI facility at the end of 2004. No additional SFSCs were added during 2005. The SFSCs are performing as designed; consequently, there are no effluents from this facility.

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

The following summarizes incidents of effluent monitor inoperability. In all cases, compensatory measures were taken as required by the Offsite Dose Calculation Manual.

The Reactor Building gaseous effluent sample pump was declared inoperable on 12/06/04. The component could not be restored within 30 days due to problems identifying which component was causing the pump motor to trip the current overload device. The sample pump was returned to service on 1/14/05. (Condition Report 2-05-00076)

The Turbine building low range gaseous effluent monitor was declared inoperable on 5/9/05 due to the failure of the sample pump. After troubleshooting on 5/18/05, a decision was made to replace the pump. It was returned to service on 6/13/05. The component could not be restored within 30 days due to higher priority work activities. (Condition Reports 2-05-03129 and 2-05-05052)

The Reactor Building gaseous effluent sample pump was declared inoperable on 5/14/05. The component could not be restored within 30 days due to higher priority work activities. Work to replace the blower and fuses started on 6/23 and was finished on 7/13105. (Condition Report 2-05-05154)

The two condenser Offgas Post Trealtment Radiation Monitors were declared inoperable on 3/28/05 for installation of new monitors The old monitors were difficult to maintain and spare parts were no longer available as the vendor is no longer in business. This work was planned to coincide with a refueling outage to avoid the risk of offgas train isolation and reactor scram during channel functional testing. This flow path is also monitored by the main steam line radiation monitors, the offgas pretreatment radiation monitor, the charcoal vault radiation monitor, and the three reactor building exhaust stack monitors. The new monitors became operable on 6/5/05. (Condition Report 2-05-02642)

The Turbine Building gaseous exhaust sample flow rate control rack was taken out of service on 7/25/05 for routine flow rate monitor calibrations. The work was interrupted to correct some procedure deficiencies. It was subsequently placed on a higher priority task list on 8/16/05. A procedure revision was required and issued on 8/17/05 to continue work. Work was interrupted again on 8/19/05 to work on a non-ODCM-related radiation monitor. The sample rack was placed in service on 8/26/05. Corrective actions were initiated to correct repeat prioritization issues with effluent monitors. (Condition Report 2-05-06727 and Problem Evaluation Request 205-0544)

During 2003 and 2004, it was determined that the methodology used to derive Joint Frequency Distribution tables needed revision. An evaluation of the potential effect of the revision on effluent release reports since 1995 was made. The dose calculated from gaseous effluents was found to be either lower than or only slightly above the reported values and errors submitted for the year with the highest total release (2002). In all cases, the estimated doses were much lower than any Offsite Dose Calculation Manual limit. (Condition Reports 2-04-03157 and 2-04-05625)

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.

I No noble gas activity was detected above the minimum detectable level during the second 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 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 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 2005. Data is archived on the Energy Northwest Local Area Network.

Joint data recovery for 2005 was 98.8% 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 2005. 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 2005.

Calibrations performed in 2005 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 2005.

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 1.88E-03 mrem to the total body, 1.88E-03 mrem to the thyroid, and 2.33E-03 mrem to the skin. This location was at 4.01 miles in the ENE 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. The dose assessment results for this group are tabulated below.

During 2005, members of the public worked at the WNP-1 and WNP-4 industrial areas. 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 at WNP-1 and 960 hours0.0111 days 0.267 hours 0.00159 weeks 3.6528e-4 months per year at WNP-4. 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.

For environmental TLD stations at or beyond the site boundary where preoperational (background) data was acquired, no increase in ambient exposure was observed in 2005 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 only direct radiation was 2.42E+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.

7.0 REVISIONS TO THE ODCM In 2005, the ODCM was revised as follows:

ODCM Section 3.1 describes potential tritium releases from the auxiliary boiler and heating steam system. It was revised to also discuss potential tritium releases from Seal Steam Evaporator B. A commitment was made to estimate the annual tritium releases from these sources in the annual effluent report.

Tables 3-2, contains a list of controlling locations for measuring offsite dose. These are based on the annual Land Use Census and reviews of meteorological data.

Distances were revised with data obtained from a GPS unit. The site boundary sectors with the highest mixed mode and ground mode dispersion and deposition values were revised as a result of the changes to Tables 3-10 and 3-11.

Table 3-3 contains the dispersion and deposition values for the locations in Table 3-

2. Revisions to the radial distance from CGS and changes to the Joint Frequency Distribution program resulted in revision to the values presented.

Table 3-9 of the ODCM contains input values to annual offsite dose calculations.

Following the US Bureau of Census census of 2000, FSAR Table 2.1-2 was revised with the most accurate 50-mile population estimate. ODCM Table 3-9 was revised to utilize the FSAR population estimate. In addition, quarterly input variables for offsite dose analysis were added to this ODCM table. Circular references were also resolved.

Tables 3-10 and 3-11 contain historic dispersion and deposition values which were revised following changes to the Joint Frequency Distribution program. Values from this table are used when the the meteorological tower is out of service, for miscellaneous offsite dose calculations, and can be used for instrument setpoint calculations.

Table 3-14 contains a list of references. Reference 6 (population data) was changed to FSAR Table 2.1-2. Reference 9 was the same as Reference 2 so they were combined by revision of reference notes in Table 3-9.

Table 5-1 contains the locations of REMP sampling stations. Distances to the various stations were revised to improve accuracy. In addition, Station 64 was deleted as the owners will no longer permit milk samples to be taken. A new station for obtaining garden vegetation samples was added. These sample location changes were noted in the 2004 effluent report.

RFO 6.1.3 - The completion time for returning an INOPERABLE Offgas Pretreatment Radiation Monitor to OPERABLE status was increased from 72 hours8.333333e-4 days 0.02 hours 1.190476e-4 weeks 2.7396e-5 months to 30 days. While INOPERABLE, a Required Compensatory Action was added to sample and analyze the Offgas Noble Gas 30-minute decay gross gamma activity Columbia Generating Station 56 2005 Radioactive Effluent Report Columbia Generating Station 56 2005 Radioactive Effluent Report

rate. The Completion Time for this new Compensatory Action is within 8 hours9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months and every 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months thereafter. When Required Compensatory Measure G (monitoring requirements when INOPERABLE) is or cannot be met, the subsequent Required Compensatory Action was changed from "Be in Mode 2" to "Be in Mode 3" to be consistent with plant procedures for shutting down the reactor. The ODCM Bases section (B 6.1.2) was revised to reflect the preceding changes.

8.0 REVISIONS TO THE PROCESS CONTROL PROGRAM (PCP)

There were no revisions to the Process Control Program in 2005.

9.0 NEW OR DELETED LOCA1IONS FOR DOSE ASSESSMENTS AND/OR ENVIRONMENTAL MONITORING LOCATIONS 9.1 No new locations were identified from the 2005 Five-Mile Land Use Census. Dose assessments were initiated for resource recovery efforts in progress at an abandoned reactor site (WNP-4) which lies within the site boundary of the Columbia Generating Station (0.71 mi ENE).

9.2 There were no new locations for environmental monitoring formally adopted into the program.

9.3 No dose assessment or environmental monitoring locations were deleted.

10.0 MAJOR CHANGES TO RADIOACTIVE LIQUID, GASEOUS, AND SOLID WASTE TREATMENT SYSTEMS No major changes (as defined by ODCM Section 6.4.3) were made to the radioactive waste systems (liquid, gaseous, or solid) during this reporting period.
