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 Nuclear Generating Station (OCNGS) does not result in significant radiation exposure of people or the environment surrounding OCNGS and is well below the applicable levels set by the Nuclear Regulatory Commission (NRC) and the Environmental Protection Agency (EPA).There were no planned liquid radioactive effluent releases above ODCM Lower Limit of Detection (LLD) during 2009.There were three abnormal liquid releases during 2009 resulting in an estimated total exposure of < 0.001 mRem to the most limiting member of the public.On February 9, 2009 less than 1 gallon of condensation from the B Isocondenser vent leaked onto the ground. The tritium in the condensed water was 2.19E+04 pCi/I. The contaminated soil was placed in drums for disposal.

No doses were calculated since the spill was contained and soil disposed.On April 15, 2009, in preparation for work inside the Emergency Service Water (ESW) vault, water was found inside the vault. As part of standard practices for water removal, the water was pumped into drums and sampled for gamma emitters, tritium, and pH. Samples indicated elevated levels of tritium and a leak was subsequently confirmed by a monitoring well in the area. The release of tritiated water was caused by small leaks in 8-inch and 10-inch carbon steel Condensate System lines.On August 24, 2009 a leak was discovered inside the turbine building coming from the turbine building west wall penetration housing a six-inch Condensate Transfer line. The leakage was found coming from the six-inch pipe within the wall penetration.

After excavation of the pipe penetration from outside the turbine building, water was observed leaking from the pipe penetration into the excavation pit. The puddled water was pumped into drums for subsequent disposal.The maximum hypothetical calculated organ dose (GI-LLI) from iodines, tritium and particulates to any individual due to gaseous effluents was 6.56E-3 mrem, which was approximately 4.37E-02 percent of the annual limit. The maximum calculated gamma air dose in the UNRESTRICTED AREA due to noble gas effluents was 1.61 E-04 mrem, which was 1.61 E-03 percent of the annual limit.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 and100 mrem from background radiation.

The Independent Spent Fuel Storage Installation (ISFSI) is a closed system and the only 1 Oyster Creek 2009 Annual Radioactive Effluent Release Report 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 2009. Because it is a sealed unit, no radioactive material was released.Additionally, comparison of environmental sampling results to iodine and particulate gaseous effluents released, showed no radioactivity attributable to the operation of OCNGS. Both elevated and ground-level release paths were considered in this review, with total iodines released of 6.02E-04 Ci and total particulates with half-lives greater than 8 days released of 1.78E-04 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 97.8 percent and 97.8 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.2 Oyster Creek 2009 Annual Radioactive Effluent Release Report 1. Introduction In accordance with the reporting requirements of Technical Specification 3.6.E.1 applicable during the reporting period, this report summarizes the effluent release data for Oyster Creek Generating Station for the period January 1, 2009 through December 31, 2009. This submittal complies with the format 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 Plants", Revision 1, June, 1974.Meteorological data was reported in the format specified in Regulatory Guide 1.23, Revision 1, "Meteorological Monitoring Programs for Nuclear Power Plants".All vendor results were received and included in the report calculations.

Therefore the 2009 report is complete.2. Supplemental Information A. Regulatory Limits: Limit Units Receptor ODCM and 10 CFR 50, Appendix I Desian Obiective Limits 1.

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 gCi/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 (T) of the radionuclide mixture in releases of fission and activation gases as described in Regulatory Guide 1.21, "Measuring, Evaluation, and Reporting Radioactivity in Solid Wastes and Releases of Radioactive Materials in Liquid and Gaseous Effluents from Light-Water-Cooled Nuclear Power Plants," 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 and NUREG-0133, "Preparation of Radiological Effluent Technical Specifications for Nuclear Power Plants, October 1978.Therefore, average energy as described in Regulstory 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 ODCM Table 4.11.2.1.2-1.

Additional grab samples were taken from the stack 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. The data from the noble gas radiation monitor were analyzed to report net noble gas effluent activity.

If activity was found in the grab isotopic analysis, the isotopic mixture for the Noble Gas Monitor was determined from that isotopic mixture. If no activity is detected in the grab samples, Xe-135 is assumed to be the nuclide detected by the noble gas radiation monitor. Cross-check samples for the gas Marinelli were not performed in 2009. There were numerous non-gas cross-check samples that were performed in 2009. These cross-check samples gave assurance that the efficiency of the detectors had not changed.2. Particulates and lodines The method used for Gamma Isotopic Analysis is the Canberra Gamma Spectroscopy System with a particulate filter (47 mm) and charcoal cartridge, respectively.

Particulate and iodine activity was continuously sampled and analyzed in accordance with ODCM Table 4.11.2.1.2-1.

Charcoal and 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 Oyster Creek 2009 Annual Radioactive Effluent Release Report 3. Liquid Effluents During 2009, there were no planned radiological liquid releases.

Since there were no liquid discharges in 2009, there was no dose attributable to liquid effluents.

4. Tritium in Gaseous Effluents:

Air from stack effluents was passed through a desiccant column and distilled to remove the tritiated water collected.

An aliquot of the water from the distillate was analyzed using a liquid scintillation counter.5. Composite Samples and Lower Limit of Detection (LLD)Particulate air samples were composited monthly and analyzed for gross alpha, Sr-89 and Sr-90. These composites are submitted to an offsite vendor laboratory for analysis.

The ODCM required lower limit of detection for liquid and airborne releases are as follows: Liquid: LLD Principal Gamma Emitters (Mn-54, Fe-59, Co-58, Co-60, Zn-65, 1-131, Ce-141, Cs-134, Cs-137) 5E-07 pCi/ml Principal Gamma Emitters (Mo-99, Ce-144) 1E-05 pCi/mI Dissolved and Entrained Gases 1 E-05 pCi/ml H-3 1 E-05 pCi/ml Gross Alpha 1 E-07 pCi/ml Sr-89, Sr-90 5E-08 pCi/ml Fe-55 1 E-06 pCi/mI Airborne LLD Principal Gamma Emitters (Kr-87, Kr-88, Xe-133, Xe-133m, Xe-135, Xe-138) 1E-04 pCi/ml H-3 1 E-06 pCi/ml 1-131 1 E-12 pCi/ml 1-133 1E-1O0 pCi/ml Principal Gamma Emitters (Mn-54, Fe-59, Co-58, Co-60, Zn-65, Mo-99, Cs-134, Cs-137, Ce-141, Ce-144) 1E-11 pCi/mI Gross Alpha 1E-11 pCi/ml Sr-89, Sr-90 1E-11 pCi/ml 6. 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.

E. Batch Releases: There were no batch releases of liquid or gaseous effluents during 2009.F. Average Stream Flow: 5 Oyster Creek 2009 Annual Radioactive Effluent Release Report There were no planned releases of liquid effluent in 2009. See the abnormal releases section for discharge canal flows used for calculations.

G. Abnormal Releases: There were three abnormal liquid releases during 2009.1. On February 9, 2009 less than 1 gallon of condensation from the B Isocondenser vent leaked onto the ground. The tritium in the condensed water was 2.19E+04 pCi/I (8.29E-08 Ci). The contaminated soil was placed in drums for disposal.

No doses were calculated since the spill was contained and soil disposed.2. On April 15, 2009, in preparation for work inside the Emergency Service Water (ESW) vault, water was found inside the vault. As part of standard practices for water removal, the water was pumped into drums and sampled for gamma emitters, tritium, and pH. Sample analysis identified tritium levels at 102,000 pCi/I. Investigation determined that the release of tritiated water was caused by leaks in the 8-inch and 10-inch carbon steel Condensate System lines. The root cause investigation determined that the piping leaks developed due to a corrosion mechanism known as anodic dissolution.

Poor application of pipe coating left the buried pipes susceptible to this corrosion.

A bounding calculation of the doses was done. A total of 66 Ci of tritium was assumed to be released to the discharge canal over a 4 month period with a dilution flow of 500,000 gpm. The total body and organ doses were both 6.06E-04 mrem. Dose from this release is not included in the Liquid Effluents

-Summary of all Releases.3. On August 24, 2009 an eight to ten gallon per minute leak was discovered in the condenser bay. The leak was coming from the turbine building west wall penetration housing the Condensate Transfer CH-5 line, the six-inch Condensate Transfer Main Header. Two leaks were found in the pipe within the wall penetration.

A tritium concentration of 1.08E+07 pCi/I was detected.

The root cause investigation determined the cause to be galvanic corrosion.

A bounding calculation of the doses was done. A total of 2.06 Ci of tritium was assumed to be released to the discharge canal over a 7 day period with a dilution flow of 1 E+06 gpm. The total body and organ doses were both 9.36E-06mrem. Dose from this release is no included in the Liquid Effluents

-Summary of all Releases.H. Revisions to the ODCM: Revision 3 of CY-OC-170-301, Offsite Dose Calculation Manual was approved during April, 2009. A complete copy, along with detailed information justifying the changes, a determination that the changes did not reduce the accuracy or reliability of dose calculations or setpoint determination, and documentation of review and approval is in Appendix E.The following is a summary of the changes made in Revision 3." Changes to REMP sample locations." Change the reporting level of 1-131 to 2 pCi/L" Update X/Q and D/Q factors to average values from the last five years of met data." Use of the updated X/Q and D/Q factors in example dose calculations." Add a reference for a report from a vendor's hydrogeologic investigation report." A complete re-write of Table E-1 describing REMP sample stations." Updated maps of the 1-mile, 1 to 5-mile and greater than 5-mile rings showing REMP sample stations.6 Oyster Creek 2009 Annual Radioactive Effluent Release Report Revision 4 of CY-OC-1 70-301, Offsite Dose Calculation Manual, was approved during September 2009. A complete copy, along with detailed information justifying the changes, a determination that the changes did not reduce the accuracy or reliability of dose calculations or setpoint determination, and documentation of review and approval is in Appendix E.The following is a summary of the changes made in Revision 4." Administrative changes" Added projected dose requirements for liquid and gas effluents" Provided justification for liquid composite sampling methods" Provided justification for gaseous tritium sampling quarterly" Added limits for operation of the liquid and gas treatment systems 1. Radiation Effluent Monitors Out of Service More Than 30 Days Per ODCM Control 3.11, "Radioactive Liquid Effluent Monitoring Instrumentation" and Table 3.3.3.11-1 Radioactive Gaseous Effluent Monitoring Instrumentation", instrumentation requires: With less than the minimum number of radioactive gaseous effluent monitoring instrumentation channels OPERABLE, take the ACTION shown in Table 3.3.3.11-1.

Restore the inoperable instrumentation to OPERABLE status within the time specified in the ACTION or explain in the next Annual Radioactive Effluent Release Report why this inoperability was not corrected within the time specified.

The following is a discussion of instrumentation out of service for greater than 30 days: The Service Water radiation monitor was out of service from 09/25/2008 to 11/06/2009 due to inoperable instrumentation.

An investigation revealed that the monitor could not be repaired and that new components had to be manufactured.

J. Revisions to the Process Control Plan: There were no changes to the Process Control Plan in 2009.K. Releases from the Independent Spent Fuel Storage Facility: The Independent Spent Fuel Storage Installation (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 2009. Because it is a sealed unit, no radioactive material was released L. Errata: Revisions 6 and 7 of the Process Control Plan (PCP) (RW-AA-100) were approved June 2008 and December 2008 respectively.

As required by Technical Specifications, complete copies of the procedures, along with a summary of changes are included in Appendix F.The 2008 Annual Radioactive Effluent Release Report (ARERR) had errors.

For purposes of this calculation the following assumptions were made: Gaseous* Nearest resident was SE sector at 925 meters* Actual meteorology and actual gaseous effluent releases were used* All significant pathways were assumed to be present* Occupancy factor was considered 100%.Liquid There was no dose due to planned liquid releases.A summary of gaseous and liquid radiation doses to most likely exposed MEMBER OF THE PUBLIC was as follows: Location % of EfletApplicable Estimated Age Location %O Effluent A cabe Dstmed AGru Distance Direction Applicable Limit Unit Organ Dose Group (meters) (toward) Limit Noble Gas Gamma- 1.61 E-04 All 540 SSE 1.61 E-03 10 mrad Air Dose Noble Gas Beta-Air 9.65E-05 All 500 E 4.83E-04 20 mrad Dose Noble Gas Total Body 6.72E-05 All 5635 SSW 1.34E-03 5 mrem (Gamma)Noble Gas Skin (Beta) 1.03E-04 All 5635 SSW 6.87E-04 15 mrem Iodine, Particulate GI-LLI 6.56E-03 Teen 1169 ESE 4.37E-02 15 mrem& Tritium II Liquid Total body <LLD <LLD 925 SE <LLD 3 mrem Liquid Organ <LLD <LLD 925 SE <LLD 10 mrem Direct Total Body <1 All 925 SE <4 25 mrem Radiation Doses calculated were well below all ODCM and 40 CFR Part 190 limits of 75 mrem to the thyroid and 25 mrem to the total body and any other organ. The 40 CFR Part 190 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 population doses to be calculated.
