RADIOACTIVE EFFLUENT RELEASE REPORT 2008 SOUTH TEXAS PROJECT Summary and Introduction Report Summary During 2008, as in all previous years, operation of the South Texas Project created no adverse effects or health risks. The maximum radiation exposure calculated for a hypotheticalperson living at the boundary of the South Texas Project during 2008 due to operation of the South Texas Project was less than one millirem. For reference, this dose may be comparedto the average annualradiationexposure of 620 millirem to people in the United States from all sources. Of that 620 millirem, natural radiation sources in the environment accountedfor 50% of the radiation exposure, whilst 48% of the exposure occurredfrom medical procedures. Nuclear power operations contributed less than one millirem.

NCRP (2006). National Council on Radiation Protection and Measurements, Ionizing Radiation Exposure of the Population of the United States, (Bethesda, Maryland), NCRP Report No. 160.

During 2008, 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 0.016 millirem. This total represents approximately 0.06% of the limits of 40 C.F.R. §190. Based on our 2008 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 consume 64 kilograms (150 I-I

I RADIOACTIVE EFFLUENT RELEASE REPORT 2008 SOUTH TEXAS PROJECT Summary and Introduction I pounds) of vegetables grown at the residence and consumes 11 0 kilograms (250 pounds) of meat from livestock grazed at the residence. This estimated total body dose is calculated 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 on-site are listed in the report using exposure pathways not addressed by standard dose calculation methods.

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 I Radioactive Effluent Release Report summarizes the data describing the radioactive liquid and gaseous releases from the South Texas Project Electric Generating Station during 2008. The radioactive effluents from the South Texas Project are effectively monitored and controlled in accordance with regulatory requirements. I FIGURE 1-2 THEORETICAL TOTAL BODY DOSE FOR ALL PATHWAYS

Samples are also collected from ventilation systems and liquid discharges and analyzed for radioactivity. The sample and analysis methods are verified and augmented using an environmental laboratory. Radioactivity monitors continuously sample the ventilation exhaust systems. On the liquid discharge lines, radioactivity monitors automatically divert or isolate liquid effluents if the radioactivity is higher than expected. These monitors are also equipped with remote alarm indications in the control rooms and health physics offices.

Prior to and during power operation, the South Texas Project is required to evaluate radioactive material in I the environment. We are committed to sampling and analyzing environmental samples for radioactivity to support our Radiological Environmental Monitoring Program. The results of these environmental samples are reported in our Annual Environmental Operating Report. These environmental measurements affirm the accuracy of our sampling and analysis program.

The radiation monitors, and the sampling and analysis program, provide an accurate determination of the type I 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 aggressively pursue the reduction of radioactive material in liquid effluents consistent with prudent industry practices.

RADIOACTIVE EFFLUENT RELEASE REPORT 2008 SOUTH TEXAS PROJECT Summary and Introduction Each 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 from a garden, fish from the river, inhalation, and direct exposure. The highest potential hypothetical dose to an individual at the site boundary was calculated to be less than 1 millirem which is significantly less than an average person receives from natural and medical sources annually. The information presented in this report demonstrates that plant operation is consistently controlled to ensure that radioactive effluents .remain below regulatory limits and to ensure protection of the public and the environment.

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. The South Texas Project is currently owned by NRG Energy, Inc., Austin Energy and CPS Energy as tenants in common. The Houston Lighting & Power Company was the original project manager of the South Texas Project and was responsible for the engineering, design, licensing, construction, startup, and initial operation of the South Texas Project. In 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 has two, 1,350-megawatt Westinghouse pressurized water reactors.

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. The South Texas Project initiated project activities in 2008 to pursue renewal of the operating licensesfor Units 1 and 2 from the Nuclear Regulatory Commission (NRC). This process will ensure that the plant's original design and current conditions and programs can allow the .facility to continue operating safely beyond its original license deadline. The combined units produce ,enough electricity to serve more than two million homes and businesses throughout Texas. With nearly 1,300 employees, the STP Nuclear Operating Company is the largest employer and source of revenue for Matagorda County.

Supplemental Information for Effluent and Waste Disposal Secondary system 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.

Liquid Effluents Analytical Methods For Liquid Releases Liquid batch releases include waste liquid treated by the liquid waste processing, system and secondary system chehmical 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 A3-1 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 A3-1 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.

RADIOACTIVE EFFLUENT RELEASE REPORT 2008 SOUTH TEXAS PROJECT Supplemental Information for Effluent and Waste Disposal 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 thirty 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. This data is based upon waste generated from units one and two.

The dilution water flow used to estimate the individual dose due to ingestion of saltwater fish and saltwater invertebrates (shrimp) harvested from the Colorado River was 5.36E+1 1 liters per year for the years of 1989 through 2008. 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 2008 as the result of a diversion channel that routes the Colorado River into Matagorda Bay. : The dilution water flow used to I 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 2008. 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 I

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 I 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 U

The 2008 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.

I 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 I

protection reasons. These containment purges are classified as batch releases.

Lower Limit of Detection I

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 I

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 2008 SOUTH TEXAS PROJECT Supplemental Information for Effluent and Waste Disposal 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 2008, Thermoluminescent Dosimeters were placed along the protected area fence surrounding Units 1 and 2 of the South Texas Project, on the fence of the Onsite Staging Facility (Outside Storage), along the walls of OSF Warehouse D, and around the Old Steam Generator Storage Facility 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 2008, Thermoluminescent Dosimeter measurements were typical of historical background readings.

In accordance with the ODCM, the dose due to direct radiation can be estimated taking the highest TLD measurement, less background, and correcting for the distance to the site boundary using 2 2 Dosedirect = TLD * (PA) / (RD)

Where TLD = background corrected TLD annual dose, mR/yr PA = distance from source of radiation to the TLD location, meters RD = distance from the source of radiation to the closest site boundary, meters The TLD average dose rate is the average of the four quarterly values for the highest location less the quarterly average background at the site boundary. The highest average TLD dose rate was 23.1 mR/quarter for station #24 on the south side of the OSF (Warehouse D), as shown in Figure 8-1. The value for TLD may be calculated as shown below where the historical site boundary background of 15.4 mR/quarter is used to find the net rate attributable to waste stored onsite.

TLD = 23.1 - 15.4 = 7.7 mR/quarter or TLD =.(7.7 mR/quarter) * (4 quarters/yr) = 30.8 mrem/yr assuming an mR is about equal to an mrem The approximate distances PA and RD are estimated using field measurements and global positioning satellite technology. The total dose to a hypothetical member of the public at the site boundary could be calculated as below: /

Dosedirect = (30.8 mrem/yr) * (24.4 meters) 2 / (960 meters) 2 = 0.02 mrem/yr This assumes someone is positioned permanently at the fence west-north west of the OSF (Warehouse D). A real person might traverse this area twice daily (to and from work) for a total exposure time of Exposure time(real person) = (250 work days per year) * (4 minutes per trip) * (2 trips per day) 2-9

I RADIOACTIVE EFFLUENT RELEASE REPORT 2008 SOUTH TEXAS PROJECT Supplemental Information for Effluent and Waste Disposal 1 Exposure time(real person) = 2000 minutes = 0.00381 yr Dosedirect = 0.02 mrem/yr

0.00381 yr = 0.00008 mrem in 2008 5 In summary, a realistic dose of 0.00008 mrem was delivered to a member of the public offsite in 2008 although a hypothetical maximum dose of 0.02 mrem was possible at the nearest offsite location. i 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 i fence could receive less than one millirem from direct radiation. The most exposed employee on site who is also a member of the public would be a grounds keeper whose job required him to work in the vicinity of Warehouse "D" for radioactive waste. If such anI individual worked 10 hours1.157407e-4 days 0.00278 hours 1.653439e-5 weeks 3.805e-6 months once a quarter at the fence nearest the highest dose rate waste, his direct radiation dose could be calculated as follows: 5 Dose (mrem) = 40 * [(13.5+21.8+34.9+22.3) / 4 - 15.4] / 91 / 24 0.14 where I 40 = 10 hours1.157407e-4 days 0.00278 hours 1.653439e-5 weeks 3.805e-6 months per quarter times four quarters 13.5 =

Dose to Member of the Public from Direct Radiation and Radioactive Effluents Inside the i Site Boundary A hypothetical Member of the Public outside the protected area fence but inside the site boundary could receive approximately 0.28 millirem from radioactive effluents due to inhalation and immersion. This dose plus the direct radiation dose would yield 0.42 millirem, a small fraction of the 10 C.F.R. §20.1301 annual limit.

RADIOACTIVE EFFLUENT RELEASE REPORT 2008 SOUTH TEXAS PROJECT Supplemental Information for Effluent and Waste Disposal Dose to Member of the Public from Radioactive Effluents Outside the Site Boundary using ODCM Exposure Pathways During 2008,,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 0.016 millirem. This total represents approximately 0.064% of the limits of 40 C.F.R. §190. Based on our 2008 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 consume 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 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 twenty one hundred curies of tritium were released to the Main Cooling Reservoir during 2008. 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. 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 the EPA code Jclt3 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. § 190. A more complete. description of the tritium dose to gaseous receptors from liquid effluent was evaluated by Condition Report 05-8815.

The Land Use Census identified no changes in the nearest residents within five miles. I Radioactive Waste Treatment System Design Modification Description (reference, Offsite Dose Calculation Manual Controls, 6.15)

The only major design modification to the radioactive waste systems implemented during 2008 was the addition of a new flow element and controller for 1/2-WG-FV-4653 downstream of the glycol chiller in the gaseous waste processing system. This modification was performed to enhance the ability of operations to maintain steady flow through the gaseous waste processing system. Prior to this modification, the plant had numerous difficulties with system shutdown due 1 to erratic flow in the system. This was attributed to moisture buildup in FE-4653 (upstream of the chiller) which caused inaccurate flow measurements to be sent to the controller for WG-FV-4653. By installing a new flow element downstream of the chiller that could control this valve, a1 steadier flow could be maintained and system shutdowns/startups could be minimized. This modification was implemented in Unit 1 by WAN 337196 on 11/24/08 and in Unit 2 by WAN 308966 on 01/25/08. The design change package for Unit 1 is 05-7322-7 and the design change package for Unit 2 is 05-7322-8. This modification did not affect the amount or rate of gaseous U

effluent released from the plant.

RADIOACTIVE EFFLUENT RELEASE REPORT 2008 SOUTH TEXAS PROJECT Results of Direct Radiation Measurements Notes for Onsite Direct Radiation Measurements I MeasurementResults Individual values normalized to a 91 day quarter.

Only the calcium sulfate elements were used in these averages.

Average Net Rate:

I Difference between the exposure rate in 2008 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 3 The 1986 background rate of 15.4 mR at the site boundary has been used to reflect the pre-operational 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

.I background exposure rate at the site boundary due to radioactive waste processing activities on the south side of Units 1 and 2. Waste processing activities during 2008 did not cause these two stations exceed the site area background.

Zero I' Zero (0 or 0.0000) indicate background levels Milliroentgen 3 Miliroentgen or mR is a unit of exposure for X-rays and gamma rays.
