RADIOACTIVE EFFLUENT RELEASE REPORT 2012 SOUTH TEXAS PROJECT Summary and Introduction 1-2 consumes 21 kilograms (46 pounds) of fish taken from Little Robbins Slough. This individual receives a submersion dose from noble gases and dose from inhaled radioactive particulates, radioiodines, carbon-14, and tritium. This hypothetical adult is assumed to consume 64 kilograms (140 pounds) of vegetables grown at the residence and consumes 110 kilograms (240 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.
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. Carbon-14 accounted for over seventy percent of the Total Body Dose reported in gaseous effluents. 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 2012. The radioactive effluents from the South Texas Project are effectively monitored and controlled in accordance with regulatory requirements.

RADIOACTIVE EFFLUENT RELEASE REPORT 2012 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. 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 two unit facility. In 1997, the STP Nuclear Operating Company, assumed operational control of the South Texas Project and responsibility for implementation of the Radioactive Effluent Control Program.
The South Texas Project has two Westinghouse pressurized water reactors. The nominal net electrical capacity of each unit is 1,250 megawatts-electric (MWe). 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 licenses for Units 1 and 2 from the Nuclear Regulatory Commission (NRC). The license renewal application was submitted to the Nuclear Regulatory Commission in October of 2010 to request authorization to operate STP, Units 1 and 2, for an additional 20 years beyond the period specified in the current licenses. The Nuclear Regulatory Commission determined that the South Texas Project submittal was sufficient to enable them to undertake a review of the application. The Nuclear Regulatory Commission review process is intended to ensure that the plants original design and current conditions and programs can allow the facility to continue operating safely beyond its original license. The combined units currently produce enough electricity to serve more than two million homes and businesses throughout Texas. With nearly 1,200 baseline employees, the STP Nuclear Operating Company is the largest employer and source of revenue for Matagorda County.

Gaseous Effluents: Fission and Activation Gases, Tritium, Iodines 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 2-4
RADIOACTIVE EFFLUENT RELEASE REPORT 2012 SOUTH TEXAS PROJECT Supplemental Information for Effluent and Waste Disposal 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.
The methodology used for estimating the quantity of carbon-14 released to the environment is described in the following section Dose to Member of the Public from Radioactive Effluents Including Carbon-14.
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 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 A3-1 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, Iron-55, and Nickel-63 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 2012 SOUTH TEXAS PROJECT Supplemental Information for Effluent and Waste Disposal 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 and radioactivity from other solid radioactive waste shipments 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 dry active solid radioactive waste shipments is estimated to be within a factor of three of the real value.
Solid Waste Shipments A total of nine shipments of radioactive filter media, spent resins, dry active and other wastes were made during the reporting period. Additionally two shipments of exempt quantities were made to an industrial landfill in Texas. A summary of the data is provided in Section 6, Solid Waste and Irradiated Fuel Shipments. This data is based upon waste generated from Units 1 and
- 2.
Radiological Impact on Man The data for the period January 1, 2012, through December 31, 2012, is provided in the Dose Accumulation (Section 7) and the Summary of Direct Radiation Table 8-1 (Section 8). The following dilution factors and dilution water flows were used for assessing the radiation doses due to radioactive liquid effluents released to unrestricted areas.

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 2012 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 2012. 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 2-8
RADIOACTIVE EFFLUENT RELEASE REPORT 2012 SOUTH TEXAS PROJECT Supplemental Information for Effluent and Waste Disposal 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 2012 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. Batch releases were not performed during the second and third quarters. These joint frequency tables for first and third quarters were omitted as the values were null or zero.
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.
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 2012, Thermoluminescent Dosimeters were placed along the protected area fence or the concrete intrusion barriers 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 2012, Thermoluminescent Dosimeter measurements were typical of previous years 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 Dosedirect = TLD * (PA)2 / (RD)2 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 2-9
RADIOACTIVE EFFLUENT RELEASE REPORT 2012 SOUTH TEXAS PROJECT Supplemental Information for Effluent and Waste Disposal 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 18.2 mR/quarter for station #22 which is located in the vicinity of the Onsite Staging Facility (outside storage), 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 = 18.2 - 15.4 = 2.8 mR/quarter or TLD = (2.8 mR/quarter) * (4 quarters/yr) = 11.2 mrem/yr assuming a mR is about equal to a 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 = (11.2 mrem/yr) * (24.4 meters)2 / (960 meters)2 = 0.007 mrem/yr This assumes someone is positioned permanently at the fence near the Onsite Storage Facility. A real person might traverse this area twice daily (to and from work) for a total exposure time of Exposure time (hypothetical person) = (250 work days per year) * (4 minutes per trip) *
(2 trips per day)
Exposure time (hypothetical person) = 2000 minutes = 0.00381 yr Dosedirect = 0.007 mrem/yr
- 0.00381 yr = 0.000028 mrem in 2012 In summary, a realistic dose of 0.000028 mrem was possible to a member of the public offsite in 2012 although a hypothetical maximum annual dose rate of 0.007 mrem/yr was calculated 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 work in the vicinity of Warehouse D for radioactive waste. If such an individual worked 10 hours1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br /> once a quarter at the fence where the dose rate was highest, their direct radiation dose could be calculated as follows:
Dose (mrem) = 40 * [(28.2-15.4)+(17.1-15.4)+(18.1-15.4)+(18.2-15.4)] / 366 / 24 = 0.091 mrem where 40 =

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 0.70 millirem from radioactive effluents due to inhalation and immersion. This dose plus the direct radiation dose would yield 0.79 millirem, a small fraction of the 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 2012, 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 0.023 millirem. This total represents approximately 0.09% of the limits of 40 C.F.R. §190. Based on our 2012 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 highest exposed individual with regard to food consumption, occupancy, and other uses of the areas in the plant vicinity.
Our dose model assumes that this theoretically highest 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 <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> per year and consumes 21 kilograms (46 pounds) of fish taken from Little Robbins Slough. This individual receives a submersion dose from noble gases and dose from inhaled radioactive particulates, radioiodines, carbon-14, and tritium. This hypothetical adult is assumed to consume 64 kilograms (140 pounds) of vegetables grown at the residence and consumes 110 kilograms (240 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 nineteen hundred curies of tritium were released to the Main Cooling Reservoir during 2012. 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 per section 4.10 of the ODCM. The 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 Iclt3 and 2004 meteorological data. The 2-11
RADIOACTIVE EFFLUENT RELEASE REPORT 2012 SOUTH TEXAS PROJECT Supplemental Information for Effluent and Waste Disposal 2-12 product of X/Q, tritium released to the MCR, and the dose factor for a population age group (87.9, 91.7, 114.2 or 20.5 millirem-cubic meter per second-curie for age groups adult, teen, child and infant, respectively) generated an estimated whole body dose of 0.1 millirem for the highest exposed population group, a small fraction of the limits of 40 C.F.R. §190.
Dose to Member of the Public from Radioactive Effluents including Carbon-14 Carbon-14 was reported as a radioactive effluent in 2010 for the first time. Carbon-14 is a naturally occurring isotope of carbon. Carbon-14 is formed naturally in the upper atmosphere and is also formed in an operating nuclear reactor, primarily through activation of oxygen molecules. The quantity of carbon-14 produced by operating nuclear reactors is significantly less than that produced naturally or from weapons testing.
The NRC published Regulatory Guide 1.21 Revision 1, Measuring, Evaluating, and Reporting Radioactivity in Solid Wastes and Releases of Radioactive Materials in Liquid and Gaseous Effluents from Light-Water-Cooled Nuclear Power Plants in 1974. This regulatory guidance recommends the content and format of this report. This report follows the recommendations of Regulatory Guide 1.21, Revision 1. In 2009 the NRC published revision 2 of Regulatory Guide 1.21 based on a risk-informed perspective for reporting principal radionuclides. This document recommended methods for estimating and reporting the quantity of carbon-14 released in gaseous effluents. The quantity of carbon-14 released from each unit was estimated using NUREG-0017, Calculation of Releases of Radioactive Materials in Gaseous and Liquid Effluents from Pressurized Water Reactors PWR-GALE Code, April 1985. A value of 7.3 curies of carbon-14 was used for each unit. The Semiannual Summation of All Releases by Quarter for All Airborne Effluents found in section 4-2 of this report lists carbon-14 in a similar manner as tritium.
ODCM dose factors were used for estimating doses to members of the public and the doses due to carbon-14 are included in the Dose Accumulations, Section 7-1 of this report. EPRI Report TR-105715, Characterization of Carbon-14 Generated by the Nuclear Power Industry, November 1995 concluded that the molecular form of carbon-14 produced in gaseous effluent is 75 to 90 percent hydrocarbons (primarily methane) with the remainder in inorganic form (carbon dioxide or carbon monoxide in gas or carbonates in liquid). This report listed the measured molecular forms of carbon-14 in gaseous effluents from two U.S.
and six German commercial pressurized water reactors. The average fraction of inorganic carbon-14 was determined to be 20 percent and the average organic fraction was determined to be 80 percent. The pathway doses were calculated using the average ratio of 1:5 for ingestion pathways, as carbon in the form of hydrocarbons is not absorbed by plants. The radiation doses from STPEGS to the public (including carbon-14) are much lower than regulatory limits and are a very small contributor to the total radiation dose the American public receives each year from natural and manmade sources.

RADIOACTIVE EFFLUENT RELEASE REPORT 2012 SOUTH TEXAS PROJECT Results of Direct Radiation Measurements 8-3 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 2012 exposure rate and the 1986 measured rate due to natural background (average rate - 15.4 mR background) / 91 days / 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> per day The pre-operational background rate of 15.4 mR at the site boundary in 1986 has been used to reflect the background 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 this background rate due to radioactive waste processing activities on the south side of Units 1 and 2.
Zero:
Zero (0 or 0.00) indicate background levels Milliroentgen:
Miliroentgen or mR is a unit of exposure for X-rays and gamma rays.
