During 2005, the estimated total body dose to a hypothetical Member of the Public with the highest probability for exposure from radioactive effluents and direct radiation was 0.02 millirem. This total represents approximately 0.07% of the limits of 40 C.F.R- §190. Based on our 2005 Land Use Census, real individuals reside in the West by Southwest Sector, app el 4,000 meters (2.5 miles) from the site. For dose calculation purposes, the residents at this location are characteiized as the theoretically exposed with regard to food consuption, occupancy, and other uses of the areas in the plant vicinity. Our dose model assumes that this theoretically exposed individual may consume the maximnum amount of food with all the food being grown or grazed at the residence. This individual receives shoreline exposure from Little Robbins Slough for 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months per year and consumes 21 kilograms (48 pounds) of fish taken from Little Robbins Slough. This individual

. receives a submersion dose fiom noble gases and dose from inhaled radioactive particulates, radioiodines, and tritium. This hypothetical adult is assumed to consumes 64 kilograms (150 pounds) of vegetables grown at the residence and consumes 110 kilograms (250 pounds) of meat from livestock grazed at the residence. This estimated total body dose is calculated using models and exposure pathways descnibed in our Ofsite Dose 1-1 cOf

Doses from releases to the environment at the South Texas Project Electric Generating Station have historically been and continue to be well below regulatory limits as shown in the following figure. Members of the public received negligible additional radiation due to the operation of the South Texas Project. This Radioactive Effluent Release Report summarizes the data describing the radioactive liquid and gaseous releases from the South Texas Project Electric Generating Station during 2005. The radioactive effluents from the South Texas Project are effectively monitored and controlled in accordance with regulatory requirements.

Samples are also collected fiom ventilation systems and liquid diswarges and analzd for radioactivity. The sample and analysis methods are verified and augmented using an envrnmental laboratory. Radioactivity monitors continuously sample the ventilation exhaust systems. On the liquid discharge fines, radioactivity monitors automatically divert or isolate liquid effluents if the radioactity is higher than expected. These monitors are also equipped with remote al indications in the control rooms and healt physics offices.

Prior to and during power operation He South Texas Prqject is required to evaluate radoactive material in the environment. We are committed to {anping and analyzing enviromental samples for radioactivity to support our Radiological Environmental Monitoring Program The results of these eronmental samples are reported in our Annual Environental Optg Report. These eronmental me mnts affirm the accuracy of our sampling and analysis program.

The radiation nonitors, and the sampling and naysis program, provide an accurate determion of the type and quantity of radioactive materials released in plant effluents. Liquid effluents are directed to the Main Cooling Reservoir that is located entirely within the site boundary. The South Texas Project continues to aggressvely pursue the reduction of radioactive material in liquid effluents consistent with pnident industry practices.

Fah year, the effluent monitoring results are summarized in this report and a hypothetical radiation dose to the population in the surrounding area is calculated based on gaseous radioactive effluents, meteorological

> conditions and liquid radioactive effluents. The hypothetical dose assumes credible paths for radioactive material to reach a member of the public, such as consumption of vegetables firm a garden, fish from the river, 1-2

NPF-76 and NPF-80, Technical Specifications and the Offsite Dose Calculation Manual.

A single submittal is made for both units combining those sections that are common. Separate tables of releases and release totals are included where separate processing systems exist.

This report includes an annual summary ofhourly meteorological measurements taken during each quarter.

This data appears as tables of wind direction and wind speed by atmospheric stability class. All assessments of radiation doses are performed in accordance with the Offsite Dose Calculation Manual.

Minimal quantities of radioactivity were released during 2005. Liquid effluents are discharged to the on-site Main Cooling Reservoir and subsequently released offsite. The radioactivity released in liquids beyond the site boundary was estimated using the South Texas Project Electric Generating Station Offsite Dose Calculation Manual. Solid radioactive waste is shipped offsite for disposal. The following table is a brief summary of the radioactive effluents and solid waste attributable to the station.

RADIOACTIVE EFFLUENT RELEASE REPORT 2005 SOUTH TEXAS PROJECT Supplemental Information for Effluent and Waste Disposal Supplemental Information for Effluent and Waste Disposal 2-1

RADIOACTIVE EFFLUENT RELEASE REPORT 2005 SOUTH TEXAS PROJECT Supplemental Information for Effluent and Waste Disposal Supplemental Information for Effluent and Waste Disposal The South Texas Project Electric Generating Station is located on 49,500,000 square meters (12,220 acres) in Matagorda County, Texas, approximately 24,000 meters (15 miles) southwest of Bay City along the west bank of the Colorado River. Until early 2005, the South Texas Project was jointly owned by Texas Genco LP, AEP Texas Central Company, the City of Austin and the City of San Antonio. In early 2005, the AEP Texas Central Company interest in the South Texas Project was transferred to Texas Genco LP and the City of San Antonio. Until late 1997, Reliant Energy HL&P was the designated licensee for the owners. On November 14, 1997, the station owners changed the licensee to STP Nuclear Operating Company, which is responsible for implementation of the Radioactive Effluent Control Program.

The South Texas Project Electric Generating Station consists of two 1,250 megawatt-electric Westinghouse pressurized water reactors. The thermal output has been up-rated by 1.4 percent increasing the electrical output. Unit 1 received a low-power testing license on August 21, 1987, obtained initial criticality on March 8, 1988, and was declared commercially operational on August 25, 1988. Unit 2 received a low-power testing license on December 16, 1988, obtained initial criticality on March 12, 1989, and was declared commercially operational on June 19, 1989. Both units together produce enough electricity to serve over one million homes.

RADIOACTIVE EFFLUENT RELEASE REPORT 2005 SOUTH TEXAS PROJECT Supplemental Information for Effluent and Waste Disposal Measurement and Approximations of Total Activity The following discussions detail the methods used to measure and approximate total activity for the following:

Gaseous Effluents: Fission and Activation Gases, Tritium, lodines and Particulates Liquid Effluents: Fission and Activation Products, Tritium, Dissolved and Entrained Gases Tables A3-1 and A4-1 of the South Texas Project Electric Generating Station Offsite Dose Calculation Manual give sampling frequencies and lower limit of detection requirements for the analysis of liquid and gaseous effluent streams.

Gaseous Effluents Analytical Methods For Gaseous Releases from the Reactor Containment Building Monthly pre-release grab samples are collected from the plant Reactor Containment Building atmosphere. These samples are analyzed on a Gamma Spectroscopy System utilizing high purity germanium detectors for noble gas, iodine and particulate activity. Tritium specific radioactivity is measured using Liquid Scintillation Counting techniques.

The radionuclide concentrations obtained are used in conjunction with the gross noble gas release rate monitoring data collected by the radiation monitoring system to estimate the release rate of each radionuclide in the effluent streams. The noble gas release rate data collected by the unit vent radiation monitor is quantified and reported as continuous mode of release. The data from the unit vent radiation monitor in conjunction with the grab sample results of the Reactor Containment Building atmosphere are used to quantify the radioactive material released.

Analytical Methods For Continuous Gaseous Releases Periodic noble gas and tritium grab samples are taken from the continuous release points such as the Unit Vent. Continuous sampling for particulates and iodine is also performed on effluent streams. These samples are analyzed for tritium and gamma radionuclides, as described above for gaseous releases. Strontium-89, Strontium-90, and gross alpha analyses were performed by the on-site Radiological Services Laboratory.

Noble gas quantification is performed by the plant radiation monitoring system using noble gas grab sample results and the gross noble gas release rate monitor.

Secondary liquid grab samples in conjunction with the mass of the secondary coolant lost are used for quantifying secondary steam releases. The radioactive material in the steam is based on grab sample results of the secondary liquid. The secondary liquid is analyzed for gamma emitters and tritium.

T.A . J .l ri .. - -- L Supplemental Information for Effluent and Waste Disposal Liquid batch releases include waste liquid treated by the liquid waste processing system and secondary chemical regeneration waste. Liquid effluents resulting from primary to secondary leakage or other plant operations are continuously monitored and are tracked as continuous releases. For batch releases, representative pre-release grab samples are taken and analyzed in accordance with Table A3-4 of the Offsite Dose Calculation Manual. For continuous releases, representative samples are collected weekly and analyzed. Radionuclide analyses are performed using a Gamma Spectroscopy System. Aliquots of each pre-release batch sample are composited in accordance with the requirements in Table A3-4 of the Offsite Dose Calculation-Manual. Tritium concentrations are determined using Liquid Scintillation Counting techniques. Dissolved and entrained gas concentrations are determined by counting grab samples on the Gamma Spectroscopy System. Strontium-89, Strontium-90, gross alpha, and Iron-55 determinations are performed by the on-site Radiological Services Laboratory.

The radionuclide concentrations obtained are used with the total volume for each batch release.

Batch Releases Liquid and gaseous summaries are compiled from permits generated using a computer-based effluent management system and plant procedures. Liquid batch releases are accounted for by individual permits. Gaseous batch releases are accounted for by monthly permits and consist of reactor containment purges for the purpose of reducing radioactive material concentrations.

Batch times represent the actual period of releases and the periods that the purge valves were open.

RADIOACTIVE EFFLUENT RELEASE REPORT 2005 SOUTH TEXAS PROJECT Supplemental Information for Effluent and Waste Disposal Estimate of Total Error Estimate of Error for Liquid Effluents The maximum error associated with volume and flow measurements, based upon plant calibration practice, is estimated to be + 1.27%. The error associated with the flow measurement is small in relation to the counting uncertainty of the radionuclide concentration analysis.

The average uncertainty associated with counting measurements is 10% or less at the 95%

confidence level.

The error associated with dilution volume is estimated to be + 10%.

Estimate of Error for Gaseous Effluents The maximum error associated with monitor readings, sample flow, vent flow, sample collection, monitor calibration and laboratory procedures are collectively estimated to be:

Fission and Activation Gases Low Activity (less than 10 microcurie per second) + 100%

Fission and Activation Gases High Activity (greater than or equal to 10 microcurie per second) + 20%

Iodines + 25%

Particulates + 25%

Tritium + 50%

The average uncertainty associated with counting measurements is 10% or less at the 95%

confidence level for fission and activation gases, iodines, particulates and tritium.

Estimate of Error for Solid Radioactive Waste The error associated with determining the volume of solid radioactive waste shipments is estimated to be + 1%. The error associated with determining the filter media, spent primary resins, and spent secondary resins radioactivity is estimated to be within a factor of two of the real value and is due primarily to waste stream sampling uncertainty. The error associated with determining the radioactivity of other solid radioactive waste shipments is estimated to be within a factor of three of the real value.

Solid Waste Shipments A total of eighteen shipments of radioactive filter media, spent resins, dry active and other wastes were made during the reporting period. A summary of the data is provided in the Section 6, Solid Waste and Irradiated Fuel Shipments.

The dilution water flow used to estimate the individual dose due to ingestion of saltwater fish and saltwater invertebrates harvested from the Matagorda Bay was 8.73E+13 liters per year for the years of 1993 through 2005 as the result of a diversion channel that routes the Colorado River into Matagorda Bay. The dilution water flow used to estimate the individual dose due to ingestion of freshwater fish from the Little Robbins Slough Area was 1.63E+10 liters per year for the years 1989 through 2005. These dilution water flows were also used for estimating individual dose due to shoreline deposits. The radioactive material reported in the Liquid Effluent tables is the amount released to the Main Cooling Reservoir and does not contribute to dose until the radioactive material is released to unrestricted areas. In order to estimate the doses due to liquid effluents, the radioactive material reported must be adjusted by the values listed in the Offsite Dose Calculation Manual, Table B4-1, "Radionuclide Fractions N(i), Reaching Off-site Bodies of Water".

Meteorological Data The 2005 meteorological data is presented in the form of joint frequency tables. Each quarter contains eight tables, one for each stability class and one for all classes combined.

A second set of joint frequency tables is provided for time periods when the reactor containment building fans were operating to remove radioactive material from the containment for personnel protection reasons. These containment purges are classified as batch releases.

Lower Limit of Detection The Lower Limit of Detection (an a priori limit) is defined as the smallest concentration of radioactive material in a sample that will yield a net count above system background that will be detected with 95% probability, and only a 5% probability of falsely concluding that a blank observation represents a "real" signal. A zero (0) value in the attached tables indicates no activity detected.

RADIOACTIVE EFFLUENT RELEASE REPORT 2005 SOUTH TEXAS PROJECT Supplemental Information for Effluent and Waste Disposal Dose to Member of the Public Dose to Member of the Public from Direct Radiation Outside the Site Boundary The Offsite Dose Calculation Manual includes the direct radiation from plant structures as a component to the dose to a hypothetical, highest exposed Member of the Public located off site due to plant operations. The Offsite Dose Calculation Manual allows measurements made near the plant structures to be used in these calculations following suitable adjustments for distance and exposure time. In 2005, Thermoluminescent Dosimeters were placed along the protected area fence surrounding Units I and 2 of the South Texas Project as pictured in Figure 8-1 of Section 8. The results of these measurements are summarized in Table 8-1 of Section 8. The table shows that in 2005 no Thermoluminescent Dosimeter stations measured more exposure than typical of natural background determined prior to operation in the vicinity of the South Texas Project. Hence no dose due to direct radiation in 2005 was delivered to a Member of the Public located off site.

Dose to Member of the Public from Direct Radiation Inside the Site Boundary A hypothetical Member of the Public inside the site boundary but outside the protected area fence could receive less than one millirem from direct radiation if they spent 2000 hours0.0231 days 0.556 hours 0.00331 weeks 7.61e-4 months a year near the protected area fence -south of Unit 2.

Dose to Member of the Public from Direct Radiation and Radioactive Effluents Inside the Site Boundary A hypothetical Member of the Public outside the protected area fence but inside the site boundary could receive approximately 0.20 millirem from radioactive effluents due to inhalation and immersion. This dose plus the direct radiation dose would yield 0.20 millirem, a small fraction of 10 C.F.R. §20.1301 annual limit.

Dose to Member of the Public from Radioactive Effluents Outside the Site Boundary using ODCM Exposure Pathways During 2005, the estimated total body dose to a hypothetical Member of the Public with the highest probability for exposure from radioactive effluents and direct radiation was 0.02 millirem. This total represents approximately 0.07% of the limits of 40 C.F.R. §190. Based on our 2005 Land Use Census, real individuals reside in the West by Southwest Sector, approximately 4,000 meters (2.5 miles) from the site. For dose calculation purposes, the residents at this location are characterized as the theoretically exposed with regard to food consumption, occupancy, and other uses of the areas in the plant vicinity. Our dose model assumes that this theoretically exposed individual may consume the maximum amount of food with all the food being grown or grazed at the residence. This individual receives shoreline exposure from Little Robbins Slough for 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months per year and consumes 21 kilograms (48 pounds) of fish taken from Little Robbins Slough. This individual receives a submersion dose from noble gases and dose from inhaled radioactive particulates, radioiodines, and tritium. This hypothetical adult is assumed to consumes 64 kilograms (150 pounds) of vegetables grown at the residence and consumes 110 kilograms (250 pounds) of meat from livestock grazed at the residence. This estimated total body dose is calculated 2-9

RADIOACTIVE EFFLUENT RELEASE REPORT 2005 SOUTH TEXAS PROJECT Supplemental Information for Effluent and Waste Disposal using models and exposure pathways described in our Offsite Dose Calculation Manual for a hypothetical individual offsite. Other dose estimates for Members of the Public onsite are listed in the report using exposure pathways not addressed by standard dose calculation methods.

Dose to Member of the Public from Radioactive Effluents Outside the Site Boundary using Liquid to Gaseous Receptor Exposure Pathways Consistent with normal operation of the units, approximately nineteen hundred curies of tritium were released to the Main Cooling Reservoir during 2005. Our ODCM models liquid, gaseous, and direct dose exposure pathways separately and lists methods for dose calculations using models and assumptions specified in Regulatory Guides issued by the Nuclear Regulatory Commission. The models used by our ODCM and NRC Regulatory Guides assume that radioactive material released in liquid effluent remains in liquid and any receptors are exposed via liquid pathways. Since some portion of the tritium released in liquid effluents evaporates from the main cooling reservoir, this section is included to provide an estimate of offsite dose from that gaseous source which is not modeled under our current licensing requirements. The Environmental Protection Agency has a code, Iclt3, approved to calculate airborne concentrations in regions around one or more area sources.

Our main cooling reservoir with a surface area of about 28,300,000 square meters (7000 acres) is an area source and contributes tritium to the atmosphere. The atmospheric dispersion factor for the WSW sector at 4000 meters was estimated to be 4.01E-07 seconds per cubic meter using this EPA model and 2004 meteorological data. The product of X/Q, tritium released to the MCR, and dose factor (87.9 millirem-cubic meter per second-curie) generated an estimated whole body dose of 0.07 millirem, a small fraction of the limits of 40 C.F.R.

C)

§190. A more complete description of the tritium dose to gaseous receptors from liquid effluent was evaluated by Condition Report 05-8815.

Sewage Sludge Land Farming Sewage sludge removed from the West Sanitary Waste Treatment System was beneficially land applied onsite during 2005. This beneficial land application is not a radioactive effluent and is only reported to document this activity. The amount of radioactive material contained in the sludge was approximately 59 microcuries. This radioactive material includes nuclides of Cobalt-60 and tritium. In accordance with Texas Commission on Environmental Quality Permit No. 04523, the sludge is incorporated into the soil after application. A soil sample collected from the area in November 2005 indicated no activity above background, confirming that the concentration in the soil is below the limits established in Title 25 of the Texas Administrative Code Section 289.202 (ddd).

RADIOACTIVE EFFLUENT RELEASE REPORT 2005 SOUT0H TEXAS PROJECT Technical Specifications and Offsite Dose Calculation Manual Controls Reporting Requirements Offsite Dose Calculation Manual Changes (reference, Technical Specifications, 6.13)

The ODCM must be formally reviewed at least once every 24-months. This review typically occurs in the fall in conjunction with the annual land use census. Any recommended changes identified since the last revision are considered at that time. Several changes to Revision 12 of the ODCM have been suggested over the past 24-months and include changes to sample location descriptions associated with the Radiological Environmental Monitoring Program (REMP). In addition, Licensing and Quality identified some corrections during the review and comment process.

The changes are summarized as follows:.

Replaced a reference to Technical Specification 6.14 with Technical Specification 6.8.3.n in a note to Table B5-1 of Part B that was not previously identified.

Some references in the ODCM were to the East Branch Little Robbins Slough rather than the East Fork. The UFSAR refers to East Fork so all occurrences of the name were changed to East Fork Little Robbins Slough.

TLD stations 38 and 40 in Table B5-3 were previously identified as necessary to meet the minimum sampling requirements of Table B5-1. That identification was removed by changing the type face from bold to normal.

A new water sampling station, #245, was added.

Some spelling errors were corrected.

These changes do not affect the methods used to calculate offsite doses or set points for effluent monitors. The changes do not affect STP's ability to meet the level of radioactive effluent control required by 10CFR20.1302, 40CFR190, 10CFR50.36a, and Appendix I to IOCFR50.

Annual Land Use Census (reference. Offsite Dose Calculation Manual Controls, 3.12.2.a)

The Land Use Census identified one resident in the east north east sector at 7200 meters ( 4.5 miles). Additionally the resident located in the west by northwest sector distance to the resident was more accurately measured resulting in a change of distance from the plant from 7200 to 6400 meters (4.5 to 4.0 miles). The changes of the residents locations will be included in the next revision of the ODCM and is tracked by condition report 06-5126.

Radioactive Waste Treatment System Design Modification Description (reference. Offsite Dose Calculation Manual Controls. 6.15)

No major design modifications were made to the gaseous, liquid, or solid radioactive waste treatment systems during this reporting period.

RADIOACTIVE EFFLUENT RELEASE REPORT 2005 SOUTH TEXAS PROJECT Technical Specifications and Offsite Dose Calculation Manual Controls Reporting Requirements Inoperable Effluent Monitoring Instrumentation Explanation (reference. Offsite Dose Calculation Manual Controls, 6.9.1.4)

For 2005, inoperable liquid effluent monitoring instruments were corrected within the time specified in Sections 3.3.3.10 of Offsite Dose Calculation Manual Controls.

For 2005, inoperable gaseous effluent monitoring instruments were corrected within the time specified in Sections 3.3.3.11 of Offsite Dose Calculation Manual Controls.

Gas Storage Tank Curie Limit Violation Description (reference, Offsite Dose Calculation Manual Controls. 6.9.1.4)

The Reactor Coolant System Vacuum Degassing System was not used during this reporting period. Therefore, the quantity of radioactive material in the Reactor Coolant System Vacuum Degassing System Storage Tanks did not exceed the limits set forth in Section 3.11.2.6 of Technical Specifications.

Unprotected Outdoor Tank Curie Limit Violation Description (reference. Offsite Dose Calculation Manual Controls, 6.9.1.4)

There are no Unprotected Outdoor Tanks at South Texas Project Electric Generating Station.

Therefore the quantity of radioactive material in any unprotected outdoor tank did not exceed the limit set forh in Section 3.11.1.4 of Technical Specifications.

Abnormal (Unplanned) Release Description (reference, Offsite Dose Calculation Manual, 6.9.1.4)

No abnormal (unplanned) releases occurred during this reporting period.

Radioactive Waste Process Control Program Changes (reference. Technical Specifications.

6.13)

There were no changes to the Radioactive Waste Process Control Program during this reporting period.

(1) Net Rate:

L)ifference between the exposure rate in 2005 and the rate measured in 1986 due to natural background (average rate - 15.4 mR background) / 91 days / 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months per day The 1986 background rate of 15.4 at the site boundary has been used to reflect the pre-operational baseline exposure rate for STP. Historically the exposure rates measured near the protected area fence have been lower than the historical background at the site boundary. However, dosimeter stations 6 and 7 have at times exceeded the background exposure rate at the site boundary due to radioactive waste processing activities on the south sides to the Units. Waste processing activities during 2005 did not cause these two stations to exceed the site area background.

Zero (-0-) indicates background levels.
