Introduction and Summary Report Summary During 2006, 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 hypothetical person living at the boundary of the South Texas Project during 2006 due to operation of the South Texas Project was less than one millirem. For reference, this dose may be compared to the average annual radiation exposure of 360 millirem to people in the United States from all sources. Natural radiation sources in the environment contribute most of the radiation exposure to people; nuclear power operations contribute less than one millirem.

During 2006, 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 0.06% of the limits of 40 C.F.R. §190. Based on our 2006 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 1-1

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 Radioactive Effluent Release Report summarizes the data describing the radioactive liquid and gaseous releases from the South Texas Project Electric Generating Station during 2006. The radioactive effluents from the South Texas Project are effectively monitored and controlled in accordance with regulatory requirements.

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 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 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.

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 1-2

RADIOACTIVE EFFLUENT RELEASE REPORT 2006 SOUTH TEXAS PROJECT Introduction and Summary 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 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.

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 of hourly 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 2006. 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 2006 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. Ownership of the South Texas Project changed in February, 2006, when the Texas Genco LP interest in the South Texas Project was acquired by NRG Energy, Inc., the City of Austin and the City Public Service Board of San Antonio 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 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.

Regulatory Limits Fission and Activation Gases The air dose due to noble gases released in gaseous effluents from each unit to areas at and beyond the Site Boundary shall be limited to the following:

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.

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.

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 2006 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%

lodines

+ 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 nineteen 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 2006 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 2006. 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 2006 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 2006 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 2006, 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.

During the last quarter of 2006, radioactive waste was staged in the Onsite Staging Facility (Outside Storage).

The results of these measurements are summarized in Table 8-1 of Section 8. The table shows that in 2006 Thermoluminescent Dosimeter stations near the OSF (Outside Storage) measured more exposure than typical of natural background determined prior to operation in the vicinity of the South Texas Project.

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 Dosedirect = TLD * (PA)2 / (RD)2 Where TLD = background corrected TLD annual dose, mrem/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 64.8 mrem/quarter for station #19 on one side of the OSF Outside Facility 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 mrem/quarter is used to find the net rate attributable to waste stored onsite.

TLD = 64.8 - 15.4 = 49.4 mR/quarter or TLD = (49.4 mR/quarter) * (4 quarters/yr) = 198 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 = (198 mremlyr) * (17.1 meters)2 / (1060 meters)2 = 0.052 mrem/yr 2-9

KADIOAC IVE EFFLUENT RELEASE REPORT 2006 SOUTH TEXAS PROJECT Supplemental Information for Effluent and Waste Disposal This assumes someone is positioned permanently at the fence west-north west of the OSF Outside Facility. A real person might traverse this area twice daily (to and from work) for a total exposure time of Exposure time(realperson) = (250 work days per year) * (4 minites per trip) * (2 trips per day)

Exposure time(real person) = 2000 minutes = 0.00381 yr Dosedirect = 0.052 mremr/yr

0.00381 yr = 0.0002 mrem in 2006 In summary, a realistic dose of 0.0002 mrem was delivered to a member of the public offsite in 2006 although a hypothetical maximum dose of 0.052 mrem was possible at the nearest offsite location.

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.

The most exposed employee on site who is also a member of the public would be a grounds keeper whose job required him to cut grass in the vicinity of the Onsite Staging Facility (Outside Storage) for radioactive waste. If such an 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:

Dose (mrem) = 40 * [(14.2 + 12.2 + 14 + 224.4) / 4 - 15.4]

91 / 24 = 0.9 where 40 =

average pre-operation dose rate, mrem/quarter 91 =

days in a standard quarter 24 =

hours per day Since most of his time would be at distances far from the fence, this dose rate could be reduced by a further factor. Assuming he was on average at least twice as far form the highest level waste as was the dosimeter on the fence, the dose above could be reduced by an additional factor of about (1/3)2 to 0.1 mrem per year. Hence, in 2006 the highest exposed individual to direct radiation on site who was a member of the public, received 0.1 mrem of direct radiation.

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 0.14 millirem from radioactive effluents due to inhalation and immersion.

This dose plus the direct radiation dose would yield 0.24 millirem, a small fraction of 10 C.F.R. §20.1301 annual limit.

RADIOACTIVE EFFLUENT RELEASE REPORT 2006 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 2006, 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 0.06% of the limits of 40 C.F.R. §190. Based on our 2006 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-two hundred curies of tritium were released to the Main Cooling Reservoir during 2006.

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 0.08 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.

RADIOACTIVE EFFLUENT RELEASE REPORT 2006 SOUTH TEXAS PROJECT Supplemental Information for Effluent and Waste Disposal Sewage Sludge Land Farming Sewage sludge removed from the West Sanitary Waste Treatment System was beneficially land applied onsite during 2006. This beneficial land application is not a radioactive effluent and is only reported to document this activity. The amount of radioactivity contained in the sludge was approximately 81 microcuries. This radioactivity 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 October 2006 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 2006 SOUTH 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. Revision 14 of the ODCM includes improvements 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.

During this review process spelling and typographical errors were corrected when found. All the formulas were retyped using the formula generation tools in Microsoft Word 2003. Tables were reformatted as was the balance of the ODCM to fully transition to Word 2003. However these changes are not identified in the revision by change bars since they do not change the intent and are cosmetic only.

The changes are summarized as follows:

1. Part A, Control 3/4.3.3.11 was revised to reflect moving Technical Specification 3.11.2.5 to Technical Requirements Manual 3.11.2.5 (page 16).

2. Part A, Table 3.3-13, Instrument 3.d was revised to clarify that if either the normal or accident Flow Rate Monitor is inoperable, the instrument is inoperable. However, only the Sample Flow Rate Monitor in use need be checked daily (page 17).

3. Part A, Table 3.3-13, Instrument 3.e was revised to clarify that if either normal or accident Sample Flow Rate Monitor is inoperable, the instrument is inoperable.

However, only the Sample Flow Rate Monitor in use need be checked daily (page 17).

4. Part A, Table 3.3-13, Instrument 3.f was added to clarify that the signal is split and the processing of the signal for RT-8010A must be checked as well (page 17).

5. Part A, Table 4.3-9, Instrument 3.e was modified and 3.f was added to clarify that the signal is split and the processing of the signal for RT-8010A must be checked as well (page 18).

6. The location of a resident in the ENE sector was refined using GPS technology and the new distance is 7200 meters rather than the previous estimate of 8000 meters (page B4-31).

7. The location of a resident in the WNW sector was refined using GPS technology and the new distance is 7200 meters rather than the previous estimate of 6400 meters (page B4-31)..

8. References to CP&L were replaced by AEP in Table B5-3 (page 135-17).

9. Supplemental sample stations associated with tritium in ground water monitoring were added to Table 135-3 (pages 135-19 and B5-20).

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 10CFR50.

RADIOACTIVE EFFLUENT RELEASE REPORT 2006 SOUTH TEXAS PROJECT Technical Specifications and Offsite Dose Calculation Manual Controls Reporting Requirements Annual Land Use Census (reference, Offsite Dose Calculation Manual Controls, 3.12.2.a)

The Land Use Census identified no changes in the nearest residents within five miles.

In last year's report we incorrectly stated that the change in distance from the plant for the resident in the west by northwest sector was from 7200 to 6400 meters, the newly measured distance was 7200 meters. The distances to various gaseous dose pathway receptors may be found on page B4-31 of the ODCM attached to this report.

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.

Inoperable Effluent Monitoring Instrumentation Explanation (reference, Offsite Dose Calculation Manual Controls, 6.9.1.4)

For 2006, inoperable liquid effluent monitoring instruments were corrected within the time specified in Sections 3.3.3.10 of Offsite Dose Calculation Manual Controls.

For 2006, 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 forth in Section 3.11.1.4 of Technical Specifications.

RADIOACTIVE EFFLUENT RELEASE REPORT 2006 SOUTH TEXAS PROJECT Results of Direct Radiation Measurements Notes for Onsite Direct Radiation Measurements Measurement Results Individual values normalized to a 91 day quarter.

Only the calcium sulfate elements were used in these averages.

Average Net Rate:

Difference between the exposure rate in 2006and 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 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, monitoring 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 side of Units 1 and 2. Waste processing activities during 2006 did not cause these two stations exceed the site area background.

During the last quarter of 2006, radioactive waste was staged in the Onsite Staging Facility. The monitoring stations surrounding the onsite staging facility indicated exposure rates greater than background.

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