Oyster Creek 2011 Annual Radioactive Effluent Release Report EXECUTIVE

SUMMARY

Effluents are strictly monitored to ensure that radioactivity released to the environment is as low as reasonably achievable and does not exceed regulatory limits. Effluent control includes the operation of monitoring systems, in-plant and environmental sampling and analyses programs, quality assurance programs for effluent and environmental programs, and procedures covering all aspects of effluent and environmental monitoring.

Both radiological environmental and effluent monitoring indicate that the operation of Oyster Creek Generating Station (OCGS) does not result in significant radiation exposure of the people or the environment surrounding OCGS and is well below the applicable levels set by the Nuclear Regulatory Commission (NRC) and the Environmental Protection Agency (EPA).

There were liquid radioactive effluent releases during 2011 of concentrations of tritium too low to detect at an LLD of 200 picocuries per liter (pCi/L) at the New Jersey Pollution Discharge Elimination System (NJPDES) permitted main condenser outfall. The releases were part of nearly continuous pumping of groundwater at approximately 70 gpm containing low levels of tritium and no detectable gamma. Exelon and the State of New Jersey Department of Environmental Protection (NJDEP) agreed to this remediation action instead of natural attenuation to address concentrations of tritium in groundwater. Well 73 and supporting equipment and piping were installed to pump groundwater to the intake structure at the inlet of the main circulating water pumps. Provisions were established for both batch and continuous releases of groundwater. There was one Batch release in August 2011 and nearly continuous releases for the entire year of 2011. Nearly Continuous releases occurred from January 1, 2011 through December 31, 2011 with a total of 3.28E+07 gallons of groundwater pumped resulting in 9.63E-01 Ci of tritium released to the discharge canal. The dose to the most limiting member of the public due to the release of groundwater was 4.59E-06 mrem.

There were no liquid or gaseous abnormal releases during 2011.

The maximum hypothetical calculated organ dose (GI-LLI) from iodines, tritium, carbon-14 (C-14), and particulates to any individual due to gaseous effluents was 4.42E-01 mrem, which was approximately 2.95E+00 percent of the annual limit of 15 mrem. The majority of organ dose from gaseous effluents was due to C-14. The maximum calculated gamma air dose in the UNRESTRICTED AREA due to noble gas effluents was 9.83E-03 mrem, which was 9.83E-02 percent of the annual 10 CFR 50 Appendix I, As Low As Reasonably Achievable (ALARA) limit of 10 mrem.

For comparison, the background radiation dose averages approximately 300 mrem per year in the Central New Jersey area, which includes approximately 200 mrem from naturally occurring radon gas and 100 mrem from background radiation.

The Independent Spent Fuel Storage Installation (ISFSI) is a closed system and the only exposure is due to direct radiation. Based on offsite TLD readings, dose due to direct radiation from the ISFSI was less than 1 mrem for 2011. Because it is a sealed unit, no radioactive material was released.

Oyster Creek 2011 Annual Radioactive Effluent Release Report Comparison of environmental sampling results to iodine and particulate gaseous effluents released, showed no radioactivity attributable to the operation of OCGS. Both elevated and ground-level release paths were considered in this review, with total iodines released of 1.07E-02 Ci and total particulates with half-lives greater. than 8 days released of 5.46E-02 Ci.

Joint Frequency Tables of meteorological data, per Pasquill Category, as well as for all stability classes, are included. All data was collected from the on-site Meteorological Facility. Data recoveries for the 380-foot data and the 33-foot data were 99.2 percent and 99.3 percent, respectively. The UFSAR commits to Regulatory Guide (RG) 1.23 for Meteorological Facility data recovery. RG 1.23 requires data recovery of at least 90% on an annual basis.

Oyster Creek 2011 Annual Radioactive Effluent Release Report B. Effluent Concentration Limits:

Gaseous dose rates rather than effluent concentrations are used to calculate permissible release rates for gaseous releases. The maximum permissible dose rates for gaseous releases are defined in ODCM Controls 3.11.2.1.

The Effluent Concentration Limit (ECL) specified in 10 CFR 20, Appendix B, Table 2, Column 2 for identified nuclides, were used to calculate permissible release rates and concentrations for liquid release per ODCM Controls 3.11.1.1. The total activity

concentration at the Route 9 bridge for all dissolved or entrained gases was limited to < 2E-04 pCi/ml.

C. Average Energy (*)"

The Oyster Creek ODCM limits the instantaneous dose equivalent rates due to the release of noble gases to less than or equal to 500 mrem/year to the total body and less than or equal to 3000 mrem/year to the skin. The average beta and gamma energies (E) of the radionuclide mixture in releases of fission and activation gases as described in Regulatory Guide 1.21, "Measuring, Evaluating and Reporting Radioactivity in Solid Wastesand 'Releases of Radioactive Materials in Liquid and Gaseous Effluents from Light-Water-Cooled Nuclear Power Plant", may be used to calculate doses in lieu 'of more sophisticated. software. The Oyster Creek radioactive effluent program employs the methodologies presented in U.S. NRC Regulatory Guide 1.109 "Calculation of Annual Doses to Man from Routine Releases of Reactor Effluents for the Purpose of Evaluating Compliance with 10 CFR Part 50, Appendix I," Revision 1, October 1977. Therefore, average energy (E) as described in Regulatory Guide 1.21 is not applicable to Oyster Creek.

D. Measurements and Approximations of Total Radioactivity:

1.- Fission and Activation Gases The method used for Gamma Isotopic Analysis is the Canberra Gamma Spectroscopy System with a gas Marinelli beaker. Airborne effluent gaseous activity was continuously monitored and recorded in accordance with the Off Site Dose Calculation Manual (ODCM) Table 4.11.2.1.2-1. Additional grab samples were taken from thelstack Radioactive and Gaseous Effluent Monitoring System (RAGEMS) sample point, and ground-level release sample points and analyzed at least monthly to determine the isotopic mixture of noble gas activity released for the month. If activity was found in the grab isotopic analysis, the results are entered into Simplified Environmental Effluent Dosimetry System (SEEDS) to calculate dose and dose rates. If no activity is detected in the stack grab samples, post treatment or Off Gas Isotopic Analysis data may be used.

2. lodines The method used for Gamma Isotopic Analysis is the Canberra Gamma Spectroscopy System with a charcoal cartridge. Iodine activity was continuously sampled and analyzed in accordance with ODCM Table 4.11.2.1.2-1. Charcoal samples are taken from the stack RAGEMS sample 5

Oyster Creek 2011 Annual Radioactive Effluent Release Report point and ground-level release sample points and analyzed at least weekly to determine the total activity released from the plant based on the average vent flow rates recorded for the sampling period.

3. Particulates (half-lives > 8 days)

The method used for Gamma Isotopic Analysis is the Canberra Gamma Spectroscopy System with a particulate filter (47 mm). Particulate activity was continuously sampled and analyzed in accordance with ODCM Table 4.11.2.1.2-1. Particulate samples are taken from the stack RAGEMS sample point and ground-level release sample points and analyzed at least weekly to determine the total activity released from the plant based on the average vent flow rates recorded for the sampling period.

4. Tritium A. Gaseous Effluents Air from stack and vent effluents was passed through a desiccant column and distilled to remove the moisture collected. An aliquot of the water from the distillate was analyzed for tritium using a liquid scintillation counter. a f r m n l B. Liquid Effluents Water from liquid effluents was analyzed for tritium using a liquid scintillation counter.

5. Gross Alpha' Gross alpha was measured by an off-site vendor for, both the gas and liquid effluent composite samples.

6. Hard-To-Detects Hard-To-Detects was measured by an off-site vendor for one set of gas monthly composites. The analysis included Fe-55, 1-129, Ni-59, Ni-63, Tc-99, Am-241, Cm-242, Cm-243/244, Pu-238, Pu-239/240 and Pu241.

The results of this analysis are utilized until the next Hard-To-Detect analysis is performed.

7. Carbon-14 (C-14)

The amount of C-14 (Ci) released was estimated using the guidance from EPRI Technical Report 1021106, Estimation of Carbon-14 in Nuclear Power Plant Gaseous Effluents. The C-14 was released primarily through the stack (97%) with a small amount (3%) released through plant vents. The activity in liquid effluents was determined to not be significant.

The offsite dose from C-14 was calculated using SEEDS, which uses approved ODCM methodologies. The resulting annual dose to a child from gaseous releases of C-14 is about 4.01 E-01 mrem to the bone.

8. Liquid Effluents Groundwater containing tritium was released during 2011. For batch releases, tritium and principal gamma emitters were determined for each batch prior to release. For continuous releases, tritium and principal gamma emitters were determined for a composite sample daily. The concentration of tritium is limited to ensure concentrations were less than 200 pCi/I in the discharge canal. The gamma emitters were limited to less than detectable concentrations. Gross alpha, gross beta.and Hard-to-detect analyses (Fe-55, Ni-63, Sr-89 and Sr-90) were determined for monthly composite samples for each type of r'elease (batch or continuous).

The leaks into the groundwater were reported in the 2009 Annual Radioactive Effluent Release Report as abnormal releases. Estimates of the curies of the tritium releases were reported. Doses due to the release of the groundwater to the discharge canal were included in the report. To ensure that amount of activity discharge is accurate and limiting, the activity and doses as a result of discharges during 2011 from the groundwater remediation project are included in this report.

9. Estimated Total Error Present Procedure CY-AA-170-2100, Estimated Errors of Effluent Measurements, provides the methodology to obtain an overall estimate of the error associated with radioactive effluents.

10. Composite Samples and Lower Limit of Detection (LLD)

Particulate air samples were composited monthly and analyzed for gross alpha, Sr-89 and Sr-90. Groundwater batch and continuous releases were composited at least monthly and analyzed for gross alpha, Sr-89, Sr-90, Fe-55 and Ni-63. These composites are submitted to an offsite vendor laboratory for analysis. The ODCM required LLD for liquid and airborne releases are as follows:

Liquid: LLD Principal Gamma Emitters (Mn-54, Fe-59, Co-58, Co-60, Zn-65, Mo-99, 1-131, Ce-141, Cs-134, Cs-137) 5E-07 pCi/ml Principal Gamma Emitters (Ce-144) 5E-06 pCi/ml Dissolved and Entrained Gases 1E'05 IpCi/ml H-3 1 E-05 pCi/ml Gross Alpha 1E-07 pCi/ml Sr-89 and Sr-90 5E-08 pCi/ml Fe-55 and Ni-63 1 E-06 pCi/ml Airborne LLD Principal Gamma Emitters (Kr-87, Kr-88, Xe-133, Xe-133m, Xe-135, Xe-138) 1 E-04 pCi/ml H-3 1E-06 pCi/ml 1-131 1 E-12 pCi/ml 1-133 1E-10 pCi/ml Principal Gamma Emitters (Mn-54, Fe-59, Co-58, Co-60, Zn-65, Cs-134, Cs-137, Ce-141) 1E-11 pCi/ml Principal Gamma Emitters (Mo-99, Ce-144) 1E-10 pCi/ml Gross Alpha 1E-11 pCi/ml Sr-89, Sr-90 1E-11 pCi/ml 8

Oyster Creek 2011 Annual Radioactive Effluent Release Report H. Radiation Effluent Monitors Out of Service More Than 30 Days Per ODCM Control 3.3.3.10, "Radioactive Liquid Effluent Monitoring Instrumentation" and 3.3.3.11, Radioactive Gaseous Effluent Monitoring Instrumentation requires:

With less than the minimum number of radioactive liquid/gaseous effluent monitoring instrumentation channels OPERABLE, take the ACTION shown in Table 3.3.3.10-1/3.3.3.11-1. Make every reasonable effort to return the instrument to OPERABLE status within 30 days and, if unsuccessful, explain in the next Radioactive Effluent Release Report why the inoperability was not corrected in a timely manner.

The following is a discussion of instrumentation out.of service for greater than 30 days:

1. The Reactor Building Service Water System Effluent Line was out of service from 3/16/2011 through 5/5/2011.. The monitor was taken out of service 3/16/2011 due to a faulty Alarm locked in. The faulty locked in alarm was cleared after maintenance was performed 4/7/2011. During the period the monitor was out of service for the faulty alarm, the monitor was taken out of service for a second reason when it was identified on 3/28/11, that the Service Water Rad Alarm Setpointmay be non-conservative. The alarm setpoint calculation was recalculated and verified to be conservative and the monitor was returned to service 5/5/2011. Though the issue with the faulty locked in alarm was repaired within 30 days, the faulty alarm issue over-lapped with the alarm setpoiht issue which was not resolved within 30 days. The alarm setpoint issue was not re solved within 30 days due to the timeline with hiring a vendor to perform the new calculations, performing site reviews of the calculations and Operations acceptance of the calculations and declaring the monitor operable. Both of these issues were entered into our Corrective Action Program (CAP) and corrective actions taken have been documented per process.

1. Releases from the Independent Spent Fuel Storage Facility:

The ISFSI is a closed system and the only exposure would be due to direct radiation. This includes iodines, particulates, and noble gases. Based on offsite TLD readings, dose due to direct radiation from the ISFSI was less than 1 mrem for 2011. Because it is a sealed unit, no radioactive material was released.

10

Oyster Creek 2011 Annual Radioactive Effluent Release Report J. Program Deviations:

1. During Augmented Off Gas (AOG) sample line pressue testing conducted February 21, 2011, it was discovered that the sample line was not able to maintain pressure due to the filter assembly not being tight. The filter assembly was tightened and the pressure test was completed SAT. This issue was entered into our Corrective Action Program (CAP) and corrective actions implemented to ensure filter assemblies are tight when installed for sampling. The weekly sample results were evaluated against previous sample results for impact to sampling due to the assembly not being tight with no impact identified.

2. The groundwater remediation composite sampler was found out of service for less than one day on March 29, 2011. The composite sampler is required by ODCM Table 4.11.1'.1.1-1, Radioactive Liquid Waste Sampling and Analysis Program. There was 'enough sample in the composite sampler to perform the required analyses and the composite, sampler was immediately returned to

service.

3. The groundwater 'remediat ion composite sampler was found out of service for for approximately 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> on August 21, 2011. The composite sampler is

required by ODCM Table 4.11.1.11, 'Radioactive Liquid Waste Sampling and Analysis Program. The composite sampler was immediately returned to service and enough sample was collected in the composite sampler to perform the required analyses.

Oyster Creek 2011 Annual Radioactive Effluent Release Report Appendix C Radiological Impact to Man 24

Oyster Creek 2011 Annual Radioactive Effluent Release Report Per ODCM Administrative Control 6.2, an assessment of radiation doses to the likely most exposed MEMBER OF THE PUBLIC from reactor releases and other nearby uranium fuel cycle sources (including doses from primary effluent pathways and direct radiation) for the previous calendar year must be made to show conformance with 40 CFR Part 190, Environmental Radiation Protection Standards for Nuclear Power Operation. For purposes of this calculation the following assumptions were made:

Gaseous

Nearest resident was SE sector at 925 meters

" Actual 2011 meteorology and measured gaseous effluent releases were used

" All significant pathways were assumed to be present

" Occupancy factor was considered 100%.

Doses calculated in the discharge canal at the Route 9 bridge

" Fish, shellfish and shoreline pathways doses calculated 40 CFR Part 190 Compliance

" Thermoluminescence Dosimetry (TLD) measurements (minus average of control stations) measured direct radiation for the nearest resident

The highest calculated dose for gamma air dose and liquid total body were summed for total body dose

The highest calculated dose for gamma air dose, child bone and liquid organ were summed for organ dose

" The limits for Kr-85, 1-129, Pu-239 and other alpha-emitting transuranic radionuclides with half-lives greater than one year were not exceeded The ODCM does not require total body doses to the population and average doses to individuals in the population from gaseous effluents to a distance of 50 miles from the site to be calculated.
