Page 4 of 32

Annual Radioactive 2012 Effluent Release Report Waterford 3 Steam Electric Station 2.4 Measurements and Approximations of Total Radioactivity The quantification of radioactivity in liquid and gaseous effluents was accomplished by performing the sampling and radiological analysis of effluents in accordance with the requirements of Tables 4.11-1 and 4.11-2 of the Technical Requirements Manual (TRM).

2.4.1 Fission and Activation Gases (Noble Gases)

For continuous releases, a gas grab sample was analyzed at least monthly for noble gases. Each week a Gas Ratio (GR) was calculated according to the following equation:

Reading GR = Average Weekly Noble Gas Monitor Monitor Reading During Noble Gas Sampling The monthly sample analysis and weekly Gas Ratio were then used to determine noble gases discharged continuously for the previous week. For gas decay tank and containment purge batch releases, a gas grab sample was analyzed prior to release to determine noble gas concentrations in the batch. In all cases, the total radioactivity in gaseous effluents was determined from measured concentrations of each radionuclide present and the total volume discharged.

2.4.2 lodines, Particulates, and Tritium lodines and particulates discharged were sampled using a continuous sampler which contained a charcoal cartridge and a particulate filter. Each week the charcoal cartridge and particulate filter were analyzed for gamma emitters using gamma spectroscopy. The determined radionuclide concentrations and effluent volumes discharged were used to calculate the previous week's activity released. The particulate samples were composited and analyzed quarterly for Sr-89 and Sr-90 by a contract laboratory (Gel, Laboratories). Particulate gross alpha activity was measured weekly using alpha scintillation or gas-flow proportional counting techniques. The determined activities were used to estimate effluent concentrations in subsequent releases until the next scheduled analysis was performed. Annual Carbon-14 release estimate was obtained from the Waterford 3 Final Safety Analysis Report. Release of Carbon-14 was assumed to be continuous.

Grab samples of continuous releases were analyzed at least monthly for tritium. Containment purge batch releases are analyzed prior to release. The determined concentrations were used to estimate tritium activity in subsequent releases until the next scheduled analysis was performed.

Page 5 of 32

Annual Radioactive 2012 Effluent Release Report Waterford 3 Steam Electric Station 2.4.3 Liquid Effluents For continuous releases, samples were collected weekly and analyzed using gamma spectroscopy.

The measured concentrations were used to determine radionuclide concentrations in the following week's releases. For batch releases, gamma analysis was performed on the sample prior to release.

For both continuous and batch releases, composite samples were analyzed quarterly by a contract laboratory (Gel, Laboratories) for Sr-89, Sr-90, and Fe-55. Samples were composited and analyzed monthly for tritium and gross alpha using liquid scintillation and gas flow proportional counting techniques, respectively. For radionuclides measured in the composite samples, the measured concentrations in the composite samples from the previous month or quarter were used to estimate released quantities of these isotopes in liquid effluents during the current month or quarter when the analysis results became available.

The total radioactivity in liquid effluent releases was determined from the measured and estimated concentrations of each radionuclide present and the total volume of the effluent discharged.

2.5 Batch Releases A summary of information for gaseous and liquid batch releases is included in Table 1.

2.6 Unplanned/Abnormal Releases 2.6.1 UnplannedlAbnormal Gaseous Releases There were no unplanned/abnormal gaseous releases during the reporting period.

2.6.2 Unplanned/Abnormal Liquid Releases There were no unplanned/abnormal liquid releases during this reporting period.

Page 6 of 32

Annual Radioactive 2012 Effluent Release Report Waterford 3 Steam Electric Station 3.0 Gaseous Effluents The quantities of radioactive material released in gaseous effluents are summarized in Tables 1A, 1B, and IC. Note that there were no elevated releases, since all Waterford 3 releases are considered to be at ground level. The estimated total error in % is based upon several statistical uncertainties due to sample counting, efficiency, volume, etc.

4.0 Liquid Effluents The quantities of radioactive material released in liquid effluents are summarized in Tables 2A and 2B. The estimated total error in % is based upon several statistical uncertainties due to sample counting, efficiency, volume, etc.

5.0 Solid Wastes The summary of radioactive solid wastes shipped offsite for disposal is listed in Table 3. For certain waste forms, Waterford 3 uses volume reduction services provided by a contractor. These waste forms are included in Table 3 and the volumes reported reflect the volume of waste shipped offsite, not final disposal volumes. Final disposal volumes for wastes compacted offsite are available upon request. The estimated total error in % is based upon several statistical uncertainties due to sample counting, efficiency, volume, etc.

The standard Pasquill classification scheme, as presented in Regulatory Guide 1.23, is used to determine stability class from differential temperature measurements.

The Waterford-3 data recovery results by parameter are as follows:

Differiential Temp. 100.00D0 Wind Speed 100.00D/0 Wind Direction 100.00o/o Overall* 100.00D0/

A.

  • Simultaneous occurrence of valid data for all three parameters.

Dispersion and deposition values were determined from the 2012 data and used in the assessment of doses due to gaseous effluents released from site during the 2012 period.

Page 8 of 32

Annual Radioactive 2012 Effluent Release Report Waterford 3 Steam Electric Station 7.0 Assessment of Doses 7.1 Dose Due to Gaseous Effluents 7.1.1 Air Doses at the Site Boundary Air doses from gaseous effluents were evaluated at the closest offsite location that could be occupied continuously during the term of plant operation and that would result in the highest dose.

This location was determined by examining the atmospheric dispersion parameters (X/Q) at the closest offsite locations that could be continuously occupied during plant operation in each of the meteorological sectors surrounding the plant. The location that would have the highest dose would be that location having the most restrictive (largest) x/Q value.

Based on actual meteorological data collected during 2012, this location was determined to be in the E sector (X/Q = 1.5E-05 sec/m 3) at a distance of 1030 meters (0.64 miles) from the reactor building. Doses were assessed at this location in accordance with the methodology described in the Waterford 3 Offsite Dose Calculation Manual considering only beta and gamma exposures in air due to noble gas. The results of these assessments for the year 2012 are summarized as follows:

Beta air dose: 4.29E-03 mrad Gamma air dose: 4.60E-03 mrad The above beta and gamma air doses represent the following percentage of the annual dose limits:

0.021% of the Beta air dose limit (20 mrad) 0.046% of the Gamma air dose limit (10 mrad)

Dose calculation results are summarized by quarters in Table 5A. The doses were calculated in accordance with the methodology described in the Waterford 3 Offsite Dose Calculation Manual.

Page 9 of 32

Annual Radioactive 2012 Effluent Release Report Waterford 3 Steam Electric Station 7.1.2 Maximum Organ Dose to the Critical Receptor The maximum organ dose to a MEMBER OF THE PUBLIC from 1-131,1-133, tritium, and all radionuclides in particulate form with half-lives greater than eight (8) days in gaseous effluents released to areas at and beyond the site boundary was determined for 2012.

An assessment of the maximum organ dose was performed for the critical receptor. The critical receptor was assumed to be located at the nearest residence to the plant having the most restrictive atmospheric dispersion (X/Q) and deposition (D/Q) parameters. Furthermore, it was assumed that the receptor living at this residence consumed food products that were either raised or produced at this residence.

Using land use census and meteorological data for 2012 the residence with the highest x/Q value (8.1 E-06 sec/m 3) and the highest D/Q value (1.9E-08 m-2) was determined to be in the NE sector at a distance of 1432 meters (0.89 miles) from the reactor building. The dose calculation was performed in accordance with the methodology described in the Waterford 3 Offsite Dose Calculation Manual considering the inhalation, ground plane exposure, and ingestion pathways.

The maximum organ dose to the critical receptor excluding C-14 was determined for historical trending to be:

0.054 mrem to the child thyroid.

This represents 0.4% of the Annual Organ Dose limit (15 mrem).

The maximum organ dose to the critical receptor including C-14 was determined to be:

4.11 mrem to the child bone.

This represents 27.4% of the Annual Organ Dose limit (15 mrem).

Dose calculation results are summarized by quarters in Table 5A. The doses were calculated in accordance with the methodology described in the Waterford 3 Offsite Dose Calculation Manual.

Page 10 of 32

Annual Radioactive 2012 Effluent Release Report Waterford 3 Steam Electric Station 7.2 Doses Due to Liquid Effluents The annual doses to the maximum exposed individual, an adult, resulting from exposure to liquid effluents released during 2012 from Waterford 3 were:

1.53E-3 mrem to the Total Body.

1.59E-3 mrem to the maximum exposed organ (liver)

The above doses represent the following percentage of the Annual Dose limits:

0.05% of the Total Body Dose Limit (3 mrem), and 0.02% of the Organ Dose Limit (10 mrem).

Dose calculation results are summarized by quarter in Table 5B. The doses were calculated in accordance with the methodology described in the Waterford 3 Offsite Dose Calculation Manual.

7.3 40 CFR Part 190 Dose Evaluation In accordance with Technical Requirements Manual (TRM), Specification 3/4.11.4, Total Dose, dose evaluations to demonstrate compliance with Surveillance Requirements 4.11.4.1 and 4.11.4.2 of the Technical Requirements Manual (TRM), dealing with dose from the uranium fuel cycle, need to be performed only if quarterly doses exceed 3 mrem to the total body (liquid releases), 10 mrem to any organ (liquid releases), 10 mrad gamma air dose, 20 mrad beta air dose, or 15 mrem to any organ from radioiodines and particulates.

At no time during 2012 were any of these limits exceeded; therefore, the evaluation was not required.

Annual Radioactive 2012 Effluent Release Report Waterford 3 Steam Electric Station 7.4 Doses to Public Inside the Site Boundary The Member of the Public inside the site boundary expected to have the maximum exposure due to gaseous effluents would be an employee at the Waterford 1 and 2 fossil fuel plants, located in the NW sector at a distance of approximately 670 meters (0.42 miles) from the reactor building.

The doses for such an individual were determined by scaling the full-time occupancy doses due to airborne effluents by the occupancy time due to a normal working year. Based on an assumed occupancy of 25% (40 hour4.62963e-4 days <br />0.0111 hours <br />6.613757e-5 weeks <br />1.522e-5 months <br /> work week) and the fact that all employees are adults, the calculated doses were determined to be less than:

0.011 mrem to the maximum exposed organ (thyroid)

All doses for receptors inside the site boundary were calculated according to the methodology described in the Waterford 3 Offsite Dose Calculation Manual considering only the inhalation and ground plane exposure pathways.
