Oyster Creek 2013 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 the 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 to 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 2013 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. Continuous releases occurred approximately 361 days in 2013. The Continuous releases occurred from January 1, 2013 through December 27, 2013 with a total of 3.50E+07 gallons of groundwater pumped resulting in 2.82E-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 1.37E-06 mrem.

There were no liquid abnormal releases during 2013.

There was one gaseous abnormal release during 2013. During the annual inspection of the Old Radwaste Building exhaust fan connections to the main stack it was discovered that there were three slits in the top boot connection of exhaust fan EF-1-16 and a bolt missing in the connection of exhaust fan EF-1-17.

The maximum calculated organ dose (Bone) from iodines, tritium, carbon-14 (C-14), and particulates to any individual due to gaseous effluents was 4.93E-01 mrem, which was approximately 3.29E+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 3.60E-03 mrad, which was 3.60E-02 percent of the annual 10 CFR 50 Appendix I, As Low As Reasonably Achievable (ALARA) limit of 10 mrad.

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 1

Oyster Creek 2013 Annual Radioactive Effluent Release Report ISFSI was less than 1 mrem for 2013. Because it is a sealed unit, no radioactive material was released.

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 3.12E-03 Ci and total particulates with half-lives greater than 8 days less C-14 released of 3.82E-02 Ci.

Joint Frequency Tables of meteorological data, per Stability Classification 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 99.4 percent and 99.4 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.

c. <3 mrem Total Body Yearly dose limits

< 10 mrem Any Organ ODCM Control 3.11.1.2 4

Oyster Creek 2013 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 Ci/ml.

C. Average Energy ( E ):

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 Wastes and 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 the stack 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. Iodines 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 point and 5

Oyster Creek 2013 Annual Radioactive Effluent Release Report 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.

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, I-129, Ni-59, Ni-63, Tc-99, Am-241, Cm-242, Cm-243/244, Pu-238, Pu-239/240 and Pu241.

Fe-55 and Ni-63 have been added to the routine monthly composite analysis schedule based on previous sample results for Hard-To-Detects.

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 4.67E-01 mrem to the bone.

8. Liquid Effluents Groundwater containing tritium was released during 2013. 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/l in the discharge canal. The gamma emitters were limited to less than detectable concentrations. Gross alpha and Hard-to-detect analyses (Fe-55, Ni-63, Sr-89 and Sr-90) were determined for monthly composite samples for each type of release (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 2013 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, Sr-90, Fe-55 and Ni-63. 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, I-131, Ce-141, Cs-134, Cs-137) 5E-07 µCi/ml Principal Gamma Emitters (Ce-144) 5E-06 µCi/ml Dissolved and Entrained Gases 1E-05 µCi/ml H-3 1E-05 µCi/ml Gross Alpha 1E-07 µCi/ml Sr-89 and Sr-90 5E-08 µCi/ml Fe-55 and Ni-63 1E-06 µCi/ml Airborne LLD Principal Gamma Emitters (Kr-87, Kr-88, Xe-133, Xe-133m, Xe-135, Xe-138) 1E-04 µCi/ml H-3 1E-06 µCi/ml I-131 1E-12 µCi/ml I-133 1E-10 µCi/ml Principal Gamma Emitters (Mn-54, Fe-59, Co-58, Co-60, Zn-65, Cs-134, Cs-137, Ce-141) 1E-11 µCi/ml Principal Gamma Emitters (Mo-99, Ce-144) 1E-10 µCi/ml Gross Alpha 1E-11 µCi/ml Sr-89, Sr-90 1E-11 µCi/ml 8

Oyster Creek 2013 Annual Radioactive Effluent Release Report E. Batch Releases:

1. Liquid There were no batch releases of liquid effluents during 2013.

2. Gaseous There were no batch releases of gaseous effluents during 2013.

F. Abnormal Releases:

There were no abnormal liquid releases during 2013.

There was one abnormal gaseous release during 2013. During the performance of Work Order R2205683, which is to perform an annual inspection of the stack pad exhaust fans, three slits were discovered in the top boot of exhaust fan EF-1-16 and a bolt was missing from exhaust fan EF-1-17. These are the two exhaust fans for the Old Radwaste Building to the Main Stack. One of these two exhaust fans is in operation at all times to maintain a negative pressure in the Old Radwaste Building.

At no times do both of these fans run simultaneously as each fans is designed to provide 100% of the required flow. Engineering performed a calculation to determine a release rate that encompasses the maximum release rate regardless of which exhaust fan is in service. The activity to inspect the exhaust fans is an annual activity.

The following assumptions were made when calculating Curies released and dose:

Both exhaust fans have been leaking since the date of the last inspection until the time of the last repair, 7/29/12 through 7/25/13.

All of the activity due to particulates reported from the Main Stack was coming from the Old Radwaste Building and therefore being released as a groundlevel release from the exhaust fan leaks at the flow rate calculated by Engineering.

Oyster Creek 2013 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 Offgas Building Exhaust Gaseous Effluent Radioactive Noble Gas Monitor was out of service from 5/20/2013 through 8/9/2013. The monitor was taken out of service 5/20/2013 for failing the monitor functional test The original issue for the monitor failing the functional test was a faulty pushbutton on the alarm panel causing the alarm not to function. Parts were ordered and replaced on 6/18/2013 but the alarm still did not function as expected. After multiple troubleshooting attempts it was determined that the annunciator window card wiring was the issue. After changing the wiring in the alarm panel, all alarms responded as expected. The functional test was reperformed 8/9/2013 satisfactorily and the monitor was returned to service. This issue was entered into our Corrective Action Program (CAP) and corrective actions taken have been documented per process. All ODCM required compensatory measures were met.

I. 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 2013. Because it is a sealed unit, no radioactive material was released.

J. Program Deviations:

1. The groundwater remediation composite sampler was found with no composite collected on December 27, 2013. The composite sampler is required by ODCM Table 4.11.1.1.1-1, Radioactive Liquid Waste Sampling and Analysis Program. A manual sample was obtained per SP 10-003.

Operations department was notified that composite sampler was not working and Operations secured discharging from W-73 and Chemistry secured the composite sampler. This issue was entered into our Corrective Action Program (CAP) and corrective actions taken have been documented per process.

Oyster Creek 2013 Annual Radioactive Effluent Release Report Appendix C Radiological Impact to Man 23

Oyster Creek 2013 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 member of the public was W sector at 483 meters Actual 2013 meteorology and measured gaseous effluent releases were used All significant pathways were assumed to be present Occupancy factor was considered 22.8% (40 hour4.62963e-4 days 0.0111 hours 6.613757e-5 weeks 1.522e-5 months s/week for 50 weeks).

Liquid Doses calculated in the discharge canal at the Route 9 bridge Fish, shellfish and shoreline pathways doses calculated 40 CFR Part 190 Compliance Dosimetry measurements (minus average of control stations) measured direct radiation for the nearest member of the public. The nearest member of the public for direct radiation is considered an individual that works in the warehouse west of the site. As a worker, the individual is assumed to work 2,000 hours0 days 0 hours 0 weeks 0 months per year at this location.

Nearest resident was at SE sector at 937 meters.

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, I-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.

Oyster Creek 2013 Annual Radioactive Effluent Release Report Correction to 2012 ARERR There were two issues discovered in 2013 that impacted the amount of Curies released reported in Table A-2 but did not impact any of the Curies released in summary of all releases in Table A-1 nor any of the doses reported Appendix C, Radiological Impact to Man. No limits were exceeded.

1. During performance of the annual Augmented Off Gas (AOG) sample line pressure test per Work Order R2200914 it was discovered that there were two leaks in the sample line that diluted the sample flow from what was used to perform the original release calculations. One leak was the seal where the detector goes into the chamber; the second leak was a small leak directly downstream of an inlet isolation valve. A review determined that these leaks first occurred 8/30/2012 and continued until repairs were completed 5/2/2013.

These leaks only impact the particulate and iodine sampling from the normal sample point. All particulate and iodine samples taken during this time period were evaluated and updated based on the calculated sample flow rate provided by Engineering.

2. During the performance of Work Order R2205683, which is to perform an annual inspection of the stack pad exhaust fans, three slits were discovered in the top boot of exhaust fan EF-1-16 and a bolt was missing from exhaust fan EF-1-17.

These are the two exhaust fans for the Old Radwaste Building to the Main Stack. One of these two exhaust fans is in operation at all times to maintain a negative pressure in the Old Radwaste Building. At no times do both of these fans run simultaneously as each fans is designed to provide 100% of the required flow. Engineering performed a calculation to determine a release rate that encompasses the maximum release rate regardless of which exhaust fan is in service. Since the activity to inspect the exhaust fans is an annual activity, it was conservatively assumed that both exhaust fans have been leaking since the date of the last inspection until the time the repairs were completed, 7/29/12 through 7/25/13. Also, a conservative approach to determining dose to the public was taken that assumed that all of the activity due to particulates reported from the Main Stack was coming from the Old Radwaste Building and therefore being released as a groundlevel release from the exhaust fan leaks at the flow rate calculated by Engineering.
