Oyster Creek 2015 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 mon itoring .

Both radiological environmental and effluent monitoring indicate that the operation of Oyster Creek Generating Station (OCGS) does not result in significant rad iation 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 2015 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 277 days in 2015. The nearly continuous releases occurred from January 1, 2015 through January 30 , 2015 and April 27 , 2015 through December 31 , 2015 with a total of 2.78E+07 gallons of groundwater pumped resulting in 2.08E-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 9.86E-07 mrem.

There were no liquid abnormal releases during 2015.

There were no gaseous abnormal releases during 2015.

The maximum calculated organ dose (Bone) from iodines, tritium , carbon-14 (C-14) , and particulates to any individual due to gaseous effluents was 5.53E-01 mrem, which was approximately 3.69E+OO 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 4.86E-03 mrad, which was 4.86E-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 620 mrem per year to the average person in the United States.

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 2015. Because it is a sealed unit, no radioactive material was released .

Oyster Creek 2015 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 4.30E-03 Ci and total particulates with half-lives greater than 8 days less C-14 released of 2.69E-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 99.8 percent and 99.8 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.

Oyster Creek 2015 Annual Radioactive Effluent Release Report 1 Sources of Radiation Dose to the U.S . Population Note: The information in th is section is from the following NRC report: Radioactive Effluents from Nuclear Power Plants: Annual Report 2007 For comparison with Nuclear Power Plant (NPP) effluents, this section provides a perspective on the doses that Americans typically receive on average from natural and background rad iation.

In March 2009, the National Council on Radiation Protection and Measurements (NCRP) published Report No. 160 as an update to the 1987 NCRP Report No. 93, Ionizing Radiation Exposure of the Population of the United States (Refs. 28 , 29) . Report No. 160 describes the doses to the U.S. population from all sources of ionizing radiation for 2006 , the most recent data available at the time the report was written . The report also includes information on the variability of those doses from one individual to another. The NCRP estimated that the average person in the United States receives the equivalent of about 620 mrem of radiation dose each year. NCRP Report No. 160 describes each of the sources of radiation that contribute to this dose, including:

1. naturally-occurring sources (natural background ) such as cosmic rad iation from space, terrestrial radiation from rad ioactive materials in the earth , and naturally occurring radioactive materials in food people eat and air people breathe;

2. medical sources from diagnosis and treatment of health disorders using radioactive pharmaceuticals and radiation-producing equipment;

3. consumer products;

4. industrial processes, security devices, educational tools, and research activities;

5. exposures of workers that result from their occupations .

Figure 1.1 is a pie chart showing the relative contributions of these sources to radiation dose to the U.S. popu lation . Larger relative contri butors to dose are represented by proportionally larger sl ices of the pie . Doses to the publ ic from nuclear power generation are included in the industrial category ; doses to workers from nuclear power generation are included in the category of occupational dose.

Doses to the public due to effluents from NPPs are less than 0.1% of what the average person receives each year from all sources of radiation. Doses to workers from occupational exposures, including those received from work at NPPs, also are less than 0.1% of the average dose to a member of the public from all sources.

Oyster Creek 2015 Annual Radioactive Effluent Release Report 2 Exposure Pathways Radiological exposure pathways define the methods by which people may become exposed to radioactive material. The major pathways of concern are those which could cause the highest calculated radiation dose. These projected pathways are determined from the type and amount of radioactive material released , the environmental transport mechanism, and the use of the environment. The environmental transport mechanism includes consideration of physical factors, such as the hydrological (water) and meteorological (weather) characteristics of the area. An annual average of the water flow , wind speed , and wind direction are used to evaluate how the radionuclides will be distributed in an area for gaseous or liquid releases. An important factor in evaluating the exposure pathways is the use of the environment.

Many factors are considered such as dietary intake of residents, recreational use of the area , and the locations of homes and farms in the area.

The external and internal exposure pathways considered are shown in Figure 2.1. The release of radioactive gaseous effluents involves pathways such as external whole body exposure , deposition of radioactive material on plants, deposition on soil ,

inhalation by animals destined for human consumption , and inhalation by humans.

The release of radioactive material in liquid effluents involves pathways such as drinking water, fish , and direct exposure from the water at the shoreline while swimming .

Although radionuclides can reach humans by many different pathways, some result in more dose than others. The critical pathway is the exposure route that will provide, for a specific radionuclide , the greatest dose to a population, or to a specific group of the population called the critical group. The critical group may vary depending on the radionuclides involved , the age and diet of the group, or other cultural factors . The dose may be delivered to the whole body or to a specific organ . The organ receiving the greatest fraction of the dose is called the critical organ .

Oyster Creek 2015 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 µCi/ml.

C. Average Energy ( 'E ) :

Ihe 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 accord~nce with ODCM Table 4.11.2.1.2-1.

Charcoal samples are taken from the stack RAGEMS sample point and 9

Oyster Creek 2015 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 r~move 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, 1-129, Ni-59, Ni-63, Tc-99, Am-241, Cm-242, Cm-243/244, Pu-238, Pu-239/240 and Pu-241.

Fe-55 and Ni-63 have been added to the routine monthly composite analysis schedule based on previous sample results for Hard-To-Detects. Only nuclides that have been detected are included in Table A-2 and/or Table A-3.

Oyster Creek 2015 Annual Radioactive Effluent Release Report

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 5.27E-01 mrem to the bone.

8. Liquid Effluents Groundwater containing tritium was released during 2015. For continuous releases, tritium and principal gamma emitters were determined fbr 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 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 the amount of activity discharge is accurate and limiting, the activity and doses as a result of discharges during 2015 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.

11

Oyster Creek 2015 Annual Radioactive Effluent Release Report

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:

an airborne special interest location which was listed in error as a background location in the last revision.

Added REMP Sample Station 114 back into the REMP since it was accidently left off the list as a drinking water sample location in the last revision - Note, sample location 114 was still listed on Figure E-1 in the last revision.

Removed REMP Sample Station 39 from the REMP in the list as a background drinking water sample location and from Figure E-2.

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 13

Oyster Creek 2015 Annual Radioactive Effluent Release Report 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. There was no instrumentation out of service for greater than 30 days.

I. Releases from the Independent Spent Fuel Storage FaaiJity~

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 2015. Because it is a sealed unit, no radioactive material was released.

J. Program Deviations:

1. There were no program deviations in 2015.

Oyster Creek 2015 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 2015 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) .

Doses calculated in the discharge canal at the Route 9 Bridge.

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 . Note that for the warehouse worker total dose calculations the full year (8760 hours0.101 days 2.433 hours 0.0145 weeks 0.00333 months ) values for Noble Gas, Iodine, Particulate, Carbon-14 , Tritium and Liquid are used .

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 liqu id 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 requ ire 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.

CY-OC-170-301 Revision 7 Page 8 of 140 OYSTER CREEK GENERATING STATION OFF SITE DOSE CALCULATION MANUAL INTRODUCTION The Oyster Creek Off Site Dose Calculation Manual (ODCM) is an implementing document to the Oyster Creek Technical Specifications. The previous Limiting Conditions for Operations that were contained in the Radiological Effluent Technical Specifications (RETS) are now included in the ODCM as Radiological Effluent Controls (REC). The ODCM contains two parts:

Part I - Radiological Effluent Controls, and Part II - Calculational Methodologies.

Part I includes the following:

The Radiological Effluent Controls and the Radiological Environmental Monitoring Programs required by Technical Specifications 6.8.4

Descriptions of the information that should be included in the Annual Radioactive Effluent Release Report and the Annual Radiological Environmental Operating Report required by Technical Specifications 6.9.1.d and 6.9.1.e, resp~ctively.

Part II describes methodologies and parameters used for:

The calculation of radioactive liquid and gaseous effluent monitoring instrumentation alarm/trip set points; and

The calculation of radioactive liquid and gaseous concentrations, dose rates, cumulative yearly doses, and projected doses.

Part II also contains a list and graphical description of the specific sample locations for the radiological environmental monitoring program (REMP), and the liquid and gaseous waste treatment systems and discharge points.

102015

CY-OC-170-301 Revision 7 Page 9 of 140 PART I - RADIOLOGICAL EFFLUENT CONTROLS 1.0 DEFINITIONS The following terms are defined so that uniform interpretation of these CONTROLS may be achieved. The defined terms appear in capitalized type and are applicable throughout these CONTROLS.

1.1 OPERABLE - OPERABILITY A system, subsystem, train, component or device shall be OPERABLE or have OPERABILITY when it is capable of performing its specified function(s). Implicit in the definition shall be the assumption that all necessary attendant instrumentation, controls, normal and emergency electrical power sources,

cooling or seal water, lubrication or other auxiliary equipment that are required for the system, subsystem, train, component or device to perform its function(s) are also capable of performing their related support function(s).

A verification of OPERABILITY is an administrative check, by examination of appropriate plant records (logs, surveillance test records) to determine that a system, subsystem, train, component or device is not inoperable. Such verification does not preclude the demonstration (testing) of a given system, subsystem, train, component or device to determine OPERABILITY.

1.2 ACTION ACTION shall be that part of a CONTROL that prescribes remedial measures required under designated conditions.

1.3 CHANNEL CALIBRATION A CHANNEL CALIBRATION shall be the adjustment, as necessary, of the channel output such that it responds, with acceptable range and accuracy, to known values of the parameter that the channel monitors. The CHANNEL CALIBRATION shall encompass the entire channel, including equipment actuation, alarm, or trip.

1.4 CHANNEL CHECK A CHANNEL CHECK shall be a qualitative determination of acceptable operability by observation of channel behavior during operation. This determination shall include, where possible, comparison of the channel with other independent channels measuring the same variable.

102015

CY-OC-170-301 Revision 7 Page 10 of 140 1.5 CHANNEL FUNCTIONAL TEST CHANNEL FUNCTIONAL TEST shall be the injection of a simulated signal into the channel to verify its proper response including, where applicable, alarm and/or trip initiating actions.

1.6 CONTROL The Limiting Conditions for Operation (LCOs) that were contained in the Radiological Effluent Technical Specifications were transferred to the OFF SITE DOSE CALCULATION MANUAL (ODCM) and were renamed CONTROLS. This is to distinguish between those LCOs that were retained in the Technical Specifications and those LCOs or CONTROLS that were transferred to the ODCM.

1.7 FREQUENCY NOTATION The FREQUENCY NOTATION specified for the performance of Surveillance Requirements shall correspond to the intervals defined in Table 1.1.

1.8 REPORTABLE EVENT A REPORABLE EVENT shall be any of those conditions specified Section 50. 73 to 10CFR Part 50.

1.9 SOURCE CHECK SOURCE CHECK shall be the qualitative assessment of channel response when the channel sensor is exposed to a source of increased radioactivity.

1.10 AUGMENTED OFF GAS SYSTEM (AOG)

The AUGMENTED OFF GAS SYSTEM is designed and installed to holdup and/or process radioactive gases from the main condenser off gas system for the purpose of reducing the radioactive material content of the gases before release to the environs.

1.11 MEMBER (S) OF THE PUBLIC MEMBER (S) OF THE PUBLIC shall include all persons who are not occupationally associated with Exelon Generation and who do not normally frequent the Oyster Creek Generating Station site. This category does not include employees of the utility, its contractors, contractor employees, vendors, or persons who enter the site to make deliveries, to service equipment, work on site or for other purposes associated with plant functions. This category does include persons who use portions of the site for recreational, occupational, or other 102015

CY-OC-170-301 Revision 7 Page 11 of 140 purposes not associated with the plant. An individual is not a member of the public during any period in which the individual receives an occupational dose.

1.12 OFF SITE DOSE CALCULATION MANUAL (ODCM)

The OFF SITE DOSE CALCULATION MANUAL (ODCM) shall contain the methodology and parameters used in the calculation of Off Site doses due to radioactive gaseous and liquid effluents, in the calculation of gaseous and liquid effluent monitoring Alarm/Trip Set points, and in the conduct of the Radiological Environmental Monitoring Program. The ODCM shall also contain (1) the Radioactive Effluent Controls and Radiological Environmental Monitoring Programs required by Technical Specification Section 6.8.4 and (2) descriptions of the information that should be included in the Annual Radioactive Effluent Release Report AND Annual Radiological Environmental Operating Report required by Technical Specification Sections 6.9.1.d and 6.9.1.e, respectively.

1.13 PURGE - PURGING PURGE or PURGING shall be the controlled process of discharging air or gas from a confinement and replacing it with air or gas.

1.14 SITE BOUNDARY The SITE BOUNDARY shall be the perimeter line around OCGS beyond which the land is neither owned, leased, nor otherwise subject to control by Exelon Generation. The area outside the SITE BOUNDARY is termed OFF SITE or UNRESTRICTED AREA.

1.15 OFF SITE The area that is beyond the site boundary where the land is neither owned, leased nor otherwise subject to control by Exelon Generation. Can be interchanged with UNRESTRICTED AREA.

1.16 UNRESTRICTED AREA An UNRESTRICTED AREA shall be any area at or beyond the SITE BOUNDARY, access to which is not controlled by the licensee for purposes of protection of individuals from exposure to radiation and radioactive materials, or any area within the SITE BOUNDARY used for residential quarters or for industrial, commercial, institutional, and/or recreational purposes. Can be interchanged with OFF SITE.

102015

CY-OC-170-301 Revision 7 Page 12 of 140 1.17 DOSE EQUIVALENT 1-131 DOSE EQUIVALENT 1-131 shall be that concentration of 1-131 (micro curies per gram), which alone would produce the same thyroid dose as the quantity and isotopic mixture of 1-131, 1-132, 1-133, 1-134, and 1-135 actually present. The thyroid dose conversion factors used for this calculation shall be those listed in Table E-7 of Regulatory Guide 1.109, "Calculation of Annual Doses to Man from Routine Releases of Reactor Effluences for the Purpose of Evaluating Compliance with 10CFR Part 40 Appendix I."

1.18 DEPOSITION {D/Q)

The direct removal of gaseous and particulate species on land or water surfaces.

DEPOSITION is expressed as a quantity of material per unit area (e.g. m-2).

1.19 DOSE CONVERSION FACTOR (DCF)

A parameter calculated by the methods of internal dosimetry, which indicates the committed dose equivalent (to the whole body or organ) per unit activity inhaled or ingested. This parameter is specific to the isotope and the dose pathway. DOSE CONVERSION FACTORS are commonly tabulated in units of mrem/hr per picocurie/m 3 in air or water. They can be found in Reg Guide 1.109 appendices.

1.20 EFFLUENT CONCENTRATION (EC)

The liquid and air concentration levels which, if inhaled or ingested continuously over the course of a year, would produce a total effective dose equivalent of 0.05 rem. LEC refers to liquid EFFLUENT CONCENTRATION.

1.21 ELEVATED (STACK) RELEASE An airborne effluent plume whose release point is higher than twice the height of the nearest adjacent solid structure and well above any building wake effects*so as to be essentially unentrained. Regulatory Guide 1.111 is the basis of the definition of an ELEVATED RELEASE. Elevated releases generally will not produce any significant ground level concentrations within the first few hundred yards of the source. ELEVATED RELEASES generally have less dose consequence to the public due to the greater downwind distance to the ground concentration maximum compared to ground releases. All main stack releases at the OCGS are ELEVATED RELEASES.

1.22 FINITE PLUME MODEL Atmospheric dispersion and dose assessment model which is based on the assumption that the horizontal and vertical dimensions of an effluent plume are not necessarily large compared tg the distance that gamma rays can travel in air.

It is more realistic than the semi-infinite plume model because it considers the 102015

CY-OC-170-301 Revision 7 Page 13 of 140 finite dimensions of the plume, the radiation build-up factor, and the air attenuation of the gamma rays coming from the cloud. This model can estimate the dose to a receptor who is not submerged in the radioactive cloud. It is particularly useful in evaluating doses from an elevated plume or when the receptor is near the effluent source.

1.23 GROUND LEVEL NENT) RELEASE An airborne effluent plume which contacts the ground essentially at the point of release either from a source actually located at ground elevation or from a source well above the ground elevation which has significant building wake effects to cause the plume to be entrained in the wake and driven to the ground elevation.

GROUND LEVEL RELEASES are treated differently than ELEVATED RELEASES in that the X/Q calculation results in significantly higher concentrations at the ground elevation near the release point.

1.24 OCCUPATIONAL DOSE

. The dose received by an individual in a RESTRICTED AREA or in the course of employment in which the individual's assigned duties involve exposure to radiation and to radioactive material from licensed and unlicensed sources of radiation, whether in the possession of the licensee or other person. Occupational dose does not inClude dose received from background radiation, as a patient from medical practices, from voluntary participation in medical research programs, or as a member of the general public

1.25 "OPEN DOSE" A routine effluent dosimetry computer program that uses Reg.

Guides 1 .109 and 1.111 methodologies.

1.26 RAGEMS (RADIOACTIVE EMISSIONS MONITORING SYSTEM)

A plant system that monitors gaseous effluent releases from monitored release points. There is a RAG EMS system for the main stack (RAG EMS I) and one for the turbine building (RAGEMS II). They monitor particulates, iodine's, and noble gases.

1.27 SEMI-INFINITE PLUME MODEL Dose assessment model with the following assumptions. The ground is considered to be an infinitely large flat plate and the receptor is located at the origin of a hemispherical cloud of infinite radius. The radioactive cloud is limited to the space above the ground plane. The semi-infinite plume model is limited to immersion dose calculations.

1.28 SOURCE TERM 102015

CY-OC-170-301 Revision 7 Page 14 of 140 The activity release rate, or concentration of an actual release or potential release. The common units for the source term are* curies, curies per second, and curies per cubic centimeter, or multiples thereof (e.g., micro curies).

1.29 X/Q - ("CHI over Q")

The dispersion factor of a gaseous release in the environment calculated by a point source Gaussian dispersion model. Normal units of XIQ are sec/m 3 . The X/Q is used to determine environmental atmospheric concentrations by multiplying the source term, represented by Q (in units of µCi/sec or Ci/sec).

Thus, the plume dispersion, X/Q (seconds/cubic meter) multiplied by the source 3

term, Q (uCi/seconds) yields an environmental concentration, X (µCi/m ). X/Q is a function of many parameters including wind speed, stability class, release point height, building size, and release velocity.

1.30 SEEDS (Simplified Effluent Environmental Dosimetry System)

A routine effluent dosimetry computer program that uses Reg. Guides 1.109 and 1.111 methodologies.

TABLE NOTATIONS Occasionally, background fluctuations, interfering radionuclides, or other uncontrollable circumstances may render these LLD's unachievable.

When calculating the LLD for a radionuclide determined by gamma ray spectrometry, the background may include the typical contributions of other radionuclides normally present in the sample. The background count rate of a semiconductor detector (e.g. HPGe) is determined from background counts that are determined to be within the full width of the specific energy band used for the quantitative analysis for the radionuclide.

The principal gamma emitters for which the LLD specification will apply are exclusively the following radionuclides: Mn-54, Fe-59, Co-58, Co-60, Zn-65, Mo-99, Cs-134, Cs-137, Ce-141, and Ce-144. This list does not mean that only these nuclides are to be detected anq reported. Other peaks that are measurable and identifiable, together with the-above nuclides, shall be identified and reported. The LLD for Ce-144 is 5E-6 µCi/ml whereas the LLD for Mo-99 and the other gamma emitters is 5E-7 µCi/ml. Nuclides that are below the LLD for the analysis should not be reported.

b. A batch release is the discharge ofliquid wastes of adiscrete volume. Before sampling for analysis, each batch should be thoroughly mixed.

c. In the event a gross radioactivity analysis is performed in lieu of an isotopic analysis before a batch is discharged, a sample will be analyzed for principal gamma emitters afterwards.

d. A composite sample is one in which the quantity of liquid sampled is proportional to the quantity of liquid waste discharged and in which the method of sampling employed results in a specimen which is representative of the liquids released.

e. Analysis may be performed after release.

f. In the event a grab sample contains more than 5E-7 µCi/ml of 1-131 and principal gamma emitters or in the event the Reactor Building Service Water radioactivity monitor indicates more than 5E-7 µCi/ml radioactivity in the effluent, as applicable, sample the elevated activity effluent daily until analysis confirms the activity concentration in the effluent does not exceed 5E-7 µCi/ml. In addition a composite sample must be made up* for further analysis for all samples taken when the activity was> 5E-7 µCi/ml.

g. A composite sample is produced combining grab samples, each having a defined volume,*

TABLE NOTATIONS 1 Specific parameters of distance and direction sector from the centerline of the reactor, and additional description where pertinent, are provided for each and every sample location in Table 3.12.1-1 and Table E-1. Deviations are permitted from the required sampling schedule if specimens are unobtainable due to circumstances such as hazardous conditions, seasonal unavailability, malfunction of automatic sampling equipment, and other legitimate reasons. If specimens are unobtainable due to sampling equipment malfunction, effort shall be made to complete corrective action prior to the end of the next sampling period. All deviations from the sampling schedule shall be documented in the Annual Radiological Environmental Operating Report pursuant to CONTROL 6.1.2.4. It is recognized that, at times, it may not be possible or practicable to continue to obtain samples of the media of choice at the most desired location or time. In these instances suitable specific alternative media and locations may be chosen for the particular pathway in question and appropriate substitutions made within 30 days in the Radiological Environmental Monitoring Program given in the ODCM. Pursuant to Technical specification 6.19, submit in the next Radioactive Effluent Release Report documentation for a change in the ODCM including revised figure(s) and table for the ODCM reflecting the new location(s) with supporting information identifying the cause of the unavailability of samples for the pathway and justifying the selection of the new location(s) for obtaining samples. This applies to changes/deletions/additions of permanent sampling locations. This does not apply to one-time deviations from the sampling schedule. In those cases, it is NOT ACCEPTABLE to substitute sample media from other sources. The missed sample will be documented in the annual report, with no further actions necessary.

2 One or more instruments, such as pressurized ion chamber, for measuring and recording dose rate continuously may be used in place of, or in addition to, integrating dosimeters. The number of direct radiation monitoring stations has been reduced from the NUREG 1302 recommendation due to geographical limitations; e.g., some sectors are over water and some sectors cannot be reached due to lack of highway access, therefore the number of dosimeters has been reduced accordingly.

3 Airborne particulate sample filters shall be analyzed for gross beta radioactivity 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months or more after sampling to allow for radon and thoron daughter decay. If gross beta activity in air particulate is greater than ten times the yearly mean of control samples, gamma isotopic analysis shall be performed on the individual samples.

4 Gamma isotopic analysis means the identification and quantification of gamma-emitting radionuclides that may be attributable to the effluents from the facility.

5 Groundwater samples shall be taken when this source is tapped for drinking or irrigation purposes in areas where the hydraulic gradient or recharge properties are suitable for contamination. Extensive studies of geology and groundwater in the vicinity of the OCGS (Reference 21 and 31) have demonstrated that there is no plausible pathway for effluents from the facility to contaminate offsite groundwater, including the local 102015

CY-OC-170-301 Revision 7 Page 54 of 140 drinking water supplies. Samples of groundwater, including local drinking water wells, are collected in order to provide assurance to the public that these water resources are not impacted.

6 The purpose of this sample is to obtain background information. If it- is not practical to establish control locations in accordance with the distance and wind direction criteria, other sites which provide valid background data may be substituted 7 1-131 analysis on each composite when the dose calculated for the consumption of the water is greater than 1 mrem per year. If garden vegetation samples are unobtainable due to any legitimate reason (see (1) above), it is NOT ACCEPTABLE to substitute vegetation from other sources.

This limitation provides additional assurance that the levels of radioactive materials in bodies of water in UNRESTRICTED AREAS will result in exposures within (1) the Section II.A design objectives of Appendix I, 10 CFR Part 50, to a MEMBER OF THE PUBLIC and (2) the limits of 10 CFR Part 20.106(a) to the population. The concentration limit for dissolved or entrained noble gases is based upon the assumption that Xe-135 is the controlling radioisotope and its concentration limit in air (submersion) was converted to an equivalent concentration in water using the methods described in International Commission on Radiological Protection (ICRP)

Publication 2.

The value 1 E-8 is the limit for unidentified gross gamma or beta releases as per 10 CFR 20 Appendix B, Table 2, Column 2 "any single radionuclide ... other than alpha or spontaneous fission ... half life greater than 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months ". This provides operational flexibility while providing reasonable assurance that dose will remain less than 0.1

~~ .

The required detection capabilities for radioactive materials in liquid waste*samples are tabulated in terms of the lower limits of detection (LLDs). Detailed discussion of the LLD, and other detection limits can be found in references 25, 26, and 27.

Weekly grab samples for Service Water Effluent are composited for monthly tritium and gross alpha analysis and quarterly Sr-89/90 and Fe-55 analysis if activity is detected.

While discharging groundwater via the continuous release remediation pathway, the composite sample will be analyzed daily for principal gamma emitters and tritium. A monthly composite sample is analyzed for gross alpha, Sr-89/90, Fe-55, and Ni-63.

While discharging groundwater via the batch release mode remediation pathway, a grab sample is collected from each tank and analyzed for principal gamma emitters and tritium, a composite sample is analyzed monthly for gross alpha, Sr-89/90, Fe-55, and Ni-63.

Circulating Water Effluent is not included in Table 4.11.1.1.1-1, Radioactive Liquid Waste Sampling and Analysis Program since the Circulating Water is sampled as part of the Radiological Environmental Monitoring Program, Table 3.12.1-1, 3a, Waterborne, Surface downstream sample.

CY-OC-170-301 Revision 7 Page 64 of 140 3/4.11.1.2 DOSE This CONTROL is provided to implement the requirements of Sections II.A, Ill.A, and IV.A of Appendix I, 10 CFR Part 50. The CONTROL implements the guides set forth in Section II.A of Appendix I. The ACTION statements provide the required operating flexibility and at the same time implement the guides set forth in Section IV.A of Appendix I to assure that the releases of radioactive material in liquid effluents to UNRESTRICTED AREAS will be kept "as low as is reasonably achievable." The dose calculation methodology and parameters in the ODCM implement the requirements in Section Ill.A of Appendix I that conformance with the guides of Appendix I be shown by calculational procedures based on models and data, such that the actual exposure of a MEMBER OF THE PUBLIC through appropriate pathways is unlikely to be substantially underestimated. The equations specified in the ODCM for calculating the doses due to the actual release rates of radioactive materials in liquid effluents are consistent with the methodology provided in Regulatory Guide 1.109 and Regulatory Guide 1.113.

3/4.11.1.3 LIQUID RADWASTE TREATMENT The OPERABILITY of the liquid radwaste treatment system ensures that this system will be available for use whenever liquid effluents require treatment prior to their release to the environment. The requirement that the appropriate portions of this system be used, when specified, provides assurance that the release$ of radioactive materials in liquid effluents will be kept "as low as is reasonably achi.evable". This CONTROL implements the requirements of General Design Criterion 60 of Appendix A to 10 CFR Part 50 and the design objective given in Section 11.D of Appendix I to 10 CFR Part 50. The specified limits governing the use ofappropriate portions of the liquid radwaste treatment system were specified as a suitable fraction of the dose design objectives set forth in Section II.A of Appendix I, 10 CFR Part 50, for liquid effluents. Figure D-1-1a, Liquid Radwaste Treatment Chem Waste and Floor Drain System and Figure D-1-1 b, *Liquid Radwaste Treatment - High Purity and Equipment Drain System provides details of the Liquid Radwaste Treatment system.

3/4.11.2 GASEOUS EFFLUENTS 3/4.11.2.1 DOSE RATE This CONTROL is provided to ensure that the dose at any time at and beyond the SITE BOUNDARY from gaseous effluents will be within the annual dose limits of 10 CFR Part 20 to UNRESTRICTED AREAS. The annual dose limits are the doses associated with the concentrations of 10 CFR Part 20, Appendix B, Table 2, Column

1. These limits provide reasonable assurance that radioactive material discharged in gaseous effluents will not result in the exposure of a MEMBER OF THE PUBLIC in an UNRESTRICTED AREA either within or outside the SITE BOUNDARY, to annual average concentrations exceeding the limits specified in Appendix B, Table 2 of 10 CFR Part 20. For MEMBERS OF THE PUBLIC who may at times be within the SITE BOUNDARY, the occupancy of the individual will usually be sufficiently low to 102015

CY-OC-170-301 Revision 7 Page 65 of 140 compensate for any increase in the atmospheric diffusion factor above that for the SITE BOUNDARY. Examples of calculations for such MEMBERS OF THE PUBLIC with the appropriate occupancy factors shall be given in the ODCM. The specified release rate limits restrict, at all times, the corresponding gamma and beta dose rates above background to a MEMBER OF THE PUBLIC at or beyond the SITE BOUNDARY to less than or equal to 500 mrem/year to the total body or to less than or equal to 3000 mrem/yr to the skin. These release rate limits also restrict, at all times, the corresponding thyroid dose rate above background to a child via the inhalation pathway to less than or equal to 1500 mrem/year.

The required detection capabilities for radioactive materials in liquid waste samples are tabulated in terms of the lower limits of detection (LLDs). Detailed discussion of the LLD, and other detection limits can be found in references 2p, 26 and 27.

Tritium is sampled quarterly for gaseous effluents. Based on the consistency of the data from the quarterly sampling, the sampling frequency is adequate.

3/4.11.2.2 DOSE - NOBLE GASES This CONTROL is provided to implement the requirements of Section 11.B, Ill.A and IV.A of Appendix I, 10 CFR Part 50. The CONTROL implements the guides set forth in Section 11.B of Appendix I. The ACTION statements provide the required operating flexibility and at the same time implement the guides set forth in Section IV.A of

Appendix I to assure that the releases of radioactive material in gaseous effluents will be kept "as low as is reasonably achievable." The SURVEILLANCE REQUIREMENTS implement the requirements in Section Ill.A of Appendix I that conformance with the guides of Appendix I be shown by calculational procedures based on models and data such that the actual exposure of a MEMBER OF THE PUBLIC through appropriate pathways is unlikely to be substantially underestimated.

The dose calculation methodology and parameters established in the ODCM for calculating the doses due to the actual release rates of radioactive noble gases in gaseous effluents are consistent with the methodology provided in Regulatory Guide 1.109 and Regulatory Guide 1.111. The ODCM equations provided for determining the air doses at and beyond the SITE BOUNDARY are based upon the historical average atmospheric conditions.

3/4.11.2.3 DOSE- IODINE-131, IODINE-133, TRITIUM, AND RADIONUCLIDES IN PARTICULATE FORM This CONTROL is provided to implement the requirements of Section 11.C, Ill.A and IV.A of Appendix I, 10 CFR Part 50. The CONTROLS are the guides set forth in Section 11.C of Appendix I. The ACTION statements provide the required operating flexibility and at the same time implement the guides set forth in Section IV.A of Appendix I to assure that the releases of radioactive material in gaseous effluents to UNRERSTRICTED AREAS will be kept "as low as is reasonably achievable." The ODCM calculational methods specified in SURVEILLANCE REQUIREMENTS implement the requirements in Section Ill.A of Appendix I that conformance with the

gui<;les of Appendix I be shown by calculational procedures based on models and data 102015

CY-OC-170-301 Revision 7 Page 66 of 140 such that the actual exposure of a MEMBER OF THE PUBLIC through appropriate pathways is unlikely to be substantially underestimated. The ODCM calculational methodology and parameters for calculating the doses due to the actual release rates of the subject materials are* consistent with the methodology provided in Regulatory Guide 1.109, and Regulatory Guide 1.111. These equations also provide for determining the actual doses based upon the historical average atmospheric conditions. Th.e release rate controls for iodine-131, iodine-133, tritium, and radionuclides in particulate form with half-life greater than 8 days are dependent on the existing radionuclide pathways to man, in the areas at and beyond the SITE BOUNDARY. The pathways that were examined in the development of these calculations were: 1) individual inhalation of airborne radionuclides, 2) deposition of radionuclides onto green leafy vegetation with subsequent consumption by man, 3) deposition onto grassy areas where milk animals and meat producing animals graze with consumption of the milk and meat by man, and 4) deposition on the ground with subsequent exposure of man.

3/4.11.2.4 GASEOUS RADWASTE TREATMENT SYSTEM The OPERABILITY of the AUGMENTED OFF GAS TREATMENT SYSTEM (AOG) ensures that the system will be available for use whenever gaseous effluents require treatment prior to release to the environment The requirement that the appropriate portions of these systems be used, when specified, provides reasonable assurance that the releases of radioactive materials in gaseous effluents will be kept "as low as is reasonably achievable." This CONTROL implements the requirements of General Design Criterion 60 of Appendix A to 10 CFR Part 50, and the design objectives given in Section 11.D of Appendix I to 10 CFR Part 50. The specified limits governing the use of appropriate portions of the systems were specified as a suitable fraction of the dose design objectives set forth in Section 11.B and 11.C of Appendix I, 10 CFR Part 50, for gaseous effluents. Figure D-2-1, Gaseous Radwaste Treatment - Augmented Off gas System, Figure D-2-2, Ventilation System provide details of the Augmented Off Gas Treatment System and Figure D-2-3, AOG Ventilation System.

3/4.11.4 TOTAL DOSE This CONTROL is provided to meet the dose limitations of 40 CFR Part 190 that have now been incorporated into 10 CFR Part 20 by 46 FR 18525. The CONTROL requires the preparation and submittal of a Special Report whenever the calculated doses from plant radioactive effluents exceed 25 mrem to the total body or any organ, except the thyroid, which shall be limited to less than or equal to 75 mrem. It is highly unlikely that the resultant dose to a MEMBER OF THE PUBLIC will exceed the dose limits of 40 CFR Part t90 if the doses remain within twice the dose design objectives of ..

Appendix I, and if direct radiation doses from the unit, including outside storage tanks, etc. are kept small. The Special Report will describe a course of action that should result in the limitation of the annual dose to a MEMBER OF THE PUBLIC to within the 40 CFR Part 190 limits. For purposes of the Special Report, it may be assumed that the dose commitment to the MEMBER OF THE PUBLIC from other uranium fuel cycle sources is negligible. If the dose to any MEMBER OF THE PUBLIC is estimated to exceed the requirements of 40 CFR Part 190, the Special Report with a request for a 102015

CY-OC-170-301 Revision 7 Page 67 of 140 variance (provided the release conditions resulting in violation of 40 CFR Part 190 have not already been corrected), in accordance with the provisions of 40 CFR Part 190 and 10 CFR Part 20, is considered'to be a timely request and fulfills the requirements of 40 CFR Part 190 until NRC staff action is completed. The variance only relates to the limits of 40 CFR Part 190, and does not apply in any way to the other requirements for dose limitation of 10 CFR Part 20, as addressed in CONTROLS 3.11.1.1 and 3.11.2.1. An individual is not consitjered a MEMBER OF THE PUBLIC during any period in which he/she is engaged in carrying out any operation that is part of the nuclear fuel cycle.

102015

CY-OC-170-301 Revision 7 Page 68 of 140 3/4.12 RADIOLOGICAL ENVIRONMENTAL MONITORING BASES 3/4.12.1 MONITORING PROGRAM The radiological environmental monitoring program required by this CONTROL*

provides representative measurements of radiation and of radioactive materials in those exposure pathways and for those radionuclides that lead to the highest potential radiation exposures of MEMBERS OF THE PUBLIC resulting from the station operation. This monitoring program implementsSection IV.B.2 of Appendix I to 10 CFR Part 50 and thereby supplements the radiological effluent monitoring program by verifying that the measurable concentrations of radioactive materials and levels of radiation are not higher than expected on the basis of the effluent measurements and the modeling of the environmental exposure pathways. Guidance for this monitoring program is provided by the Radiological Assessment Branch Position on Environmental Monitoring, Revision 1, November 1979.

The required detection capabilities for environmental sample analyses are tabulated in terms of the lower limits of detection (LLDs). The LLDs required by Table 4.12.1-1 are considered optimum for routine environmental measurements in industrial laboratories. It should be recognized that the LLD is defined as an .§. priori (before the fact) limit representing the capability of a measurement system and not as an .§.

posteriori (after the fact) limit for a particular measurement.

Detailed discussion of the LLD, and other detection limits in references 25, 26, and 27.

Site-specific research, which included the installation of a groundwater monitoring well network, has demonstrated that the groundwater pathway is not a potential pathway to man from the OCGS. The surface water into which the OCGS discharges is a marine estuary containing saline water that is not used as drinking water or irrigation water by man.

3/4.12.2 LAND USE CENSUS This CONTROL is provided to ensure that changes in the use of areas at arid beyond the SITE BOUNDARY are identified and that modifications to the radiological environmental monitoring program are made if required by the results of this census.

The best information from the door-to-door survey, from aerial survey, from visual survey or consulting with local agricultural authorities shall be used. This census satisfies the requirements of Section IV.B.3 of-Appendix I to 10. CFR Part 50.

Restricting the census to gardens of greater than 50 m2 (500 ft 2) provides assurance that significant exposure pathways via leafy vegetables will be identified and monitored since a garden of this size is the minimum required to produce the quantity (26 kg/year) of leafy vegetables assumed in Regulatory Guide 1 .109 for consumption by a child. To determine this minimum garden size, the following assumptions were

" made: 1) 20% of the garden was used for growing broad leaf vegetation (i.e., similar to

. lettuce and cabbage), and 2) a vegetation yield of2 kg/m 2 .

102015

CY-OC-170-301 Revision 7 Page 73 of 140 PART II - CALCULATIONAL METHODOLOGIES 1.0 LIQUID EFFLUENTS 1.1 RADIATION MONITORING INSTRUMENTATION AND CONTROLS The liquid effluent monitoring instrumentation and controls at Oyster Creek for controlling and monitoring normal radioactive material releases in accordance with the Oyster Creek Radiological Effluent Technical Specifications are summarized as follows:

Reactor Building Service Water Effluent - The Reactor Building Service Water Effluent Line Monitor provides an alarm function only for releases into the environment.

Liquid radioactive waste flow diagrams are presented in Figures D-1-1 a, D-1-1 b, and D-1-1 c.

1.2 LIQUID EFFLUENT MONITOR SET POINT DETERMINATION Per the requirements of CONTROL 3.3.3.10, alarm set points shall be established for the liquid monitoring instrumentation to ensure that the release concentration limits of CONTROL 3.11.1.1 are met (i.e., the concentration of radioactive material released in liquid effluents to UNRESTRICTED AREAS at the U.S. route 9 bridge over the discharge canal shall not exceed the concentrations specified in 10 CFR 20 Appendix B. Table 2, Column 2, for radionuclides and 2E-04 µCi/ml for dissolved or entrained noble gases).

1.2.1 LIQUID EFFLUENT MONITORS The set points for the liquid effluent monitors at the Oyster Creek Generating Station are determined by the following equation:

A F2 s -F-'LE-C-g -F-1 + BKG Where:

S =radiation monitor alarm set point (cpm)

A =activity concentration (µCi/ml) of sample in laboratory: A = LCi g = the primary conversion factor for the instrument - the ratio of effluent radiation monitor counting rate to laboratory activity concentration in a sample of liquid (cpm per µCi/ml).

F1 =flow in the batch release line (e.g. gal/min). Value not greater than the discharge line flow alarm maximum set point.

102015

CY-OC-170-301 Revision 7 Page 74of140 F2 =flow in the discharge canal (e.g. gal/min). Value not less than the discharge canal minimum flow.

BKG =Monitoring instrument background (cpm)

FLEC =fraction or multiple of unrestricted area LEG in aqueous effluent based on sample analysis. FLEC is the ratio between the LECi and Ci. FLEC is unitless. For example: LEG for Co-60 is 3E-6 µCi/ml. If the concentration in a expected release is 6E-6 µCi/ml; then FLEC is 6E-6/3E-6 = 2.

The term" _A_ represents the count rate of a solution having the same nuclide FLEC distribution as the sample and the LEG of that mixture.

Ci =concentration of radionuclide i in.effluent, i.e., in a liquid radwaste sample tank, in reactor building service water (µCi/ml).

LECi =the unrestricted area liquid effluent concentration (LEG) of radionuclide i, i.e., 10 CFR 20, Appendix B, Table 2, Column 2 quantity for radionuclide i (µCi/ml).

In the event gross radioactivity analysis alone is used to determine the radioactivity in an effluent stream or batch, FLEC is C/1 E-8 (see 4.11.1.1.1 ),

Where:

C =the gross radioactivity concentration in effluent (µCi/ml).

1E-8 =the unrestricted area LEG for unidentified radionuclides (µCi/ml) from 4.11.1.1.1.

If the gross activity concentration, C, is below the lower limit of detection for gross activity, the value, 1E-8 µCi/ml, or the equivalent counting rate (cpm/ml) may be substituted for the factor _A_

FLEC

_A_ = 1E-8 µCi/ml FLEC .

1.2.2 SAMPLE RESULT SET POINTS Usually, when the concentration of specific radionuclides is determinable in a sample(s),

i.e., greater than the LLD, the alarm/trip set point of each liquid effluent radioactivity monitor is based upon the measurement of radioactive material in a batch of liquid to be released or in a continuous aqueous discharge.

102015

CY-OC-170-301 Revision 7 Page 75 of 140 1.2.3 ASSUMED DISTRIBUTION SET POINTS Alternatively, a radionuclide distribution that represents the distribution expected to be in the effluent if the concentration were high enough to be detectable, i.e., greater than the LLD, may be assumed. The representative distribution may be based upon past measurements of the effluent stream or upon a computed distribution.

1.3 BATCH RELEASES A sample of each batch of liquid radwaste is analyzed for 1-131 and other principal gamma emitters or for gross beta or gross gamma activity before release. The result of the analysis is used to calculate the trip set point of the radioactivity monitor on the liquid radwaste effluent line to apply to release of the batch.

1.4 CONTINUOUS RELEASES The Reactor Building. Service Water Effluent is sampled and analyzed weekly for 1-131, other principal gamma emitters. Results of analyses for the preceding week or for a period as long as the preceding 3 months are used to calculate the alarm/trip set point of the corresponding effluent radioactivity monitor in order to determine a representative value. In each case, whether batch or continuous, the monitor alarm/trip set point may be set at lower activity concentr~tion than the calculated set point.

1.5 LIQUID EFFLUENT DOSE CALCULATION -10 CFR 50 Doses resulting from the release of radioiodines and particulates must be calculated to show compliance with Appendix I of 10CFR50. Calculations will be performed at least monthly for all liquid effluents as stated in SURVEILLANCE REQUIREMENT 4.11; 1.2 and SURVEILLANCE REQUIREMENT 4.11.1.3.1 to verify that the dose to MEMBERS OF THE PUBLIC is maintained below the limits specified in CONTROL 3.11.1.2 The maximum dose to an individual from radioiodines, tritium, and radioactive particulates with half-lives of greater than eight days in liquid effluents released to unrestricted areas is determined as described in Reg. Guide 1.109. Environmental pathways that radioiodine, tritium, and particulates in liquid effluent follow to the maximally exposed MEMBER OF THE PUBLIC are assumed to be: exposure to shoreline deposits, ingestion of fish, and ingestion of shellfish. To assess compliance with CONTROL 3.11.1.2, the dose due to radioactive iodine, tritium, and particulates in liquid effluent is calculated tq a person at the Route 9 bridge who consumes fish and shellfish harvested at that location.

102015

CY-OC-170-301 Revision 7 Page 76 of 140 1.5.1 MEMBER OF THE PUBLIC DOSE- LIQUID EFFLUENTS CONTROL 3.11.1.2 limits the dose or dose commitment to MEMBERS OF THE PUBLIC from radioactive materials in liquid effluents from Oyster Creek Generating Station to those* listed in Table 1.5.1-1.

TABLE 1.5.1-1 LIQUID PATHWAY DOSE LIMITS During Any Calendar Quarter During Any Calendar Year

~ 1.5 mrem to total body < 3.0 mrem to total body

~ 5.0 mrem to any organ ~ 10.0 mrem to any organ Per the SURVEILLANCE REQUIREMENTS of 4.11.1.2, the following calculation methods shall be used for determining the dose or dose commitment due to the liquid radioactive effluents from Oyster Creek. Applicable liquid pathways to man for Oyster Creek include shoreline exposure, and ingestion of saltwater fish and shellfish. The receptor location is provided in Table A-4.

1.5.2

SHORELINE DEPOSIT DOSE The shoreline exposure pathway dose is calculated generally in the form (based on Reg. Guide 1.109):

Rapj = 110000 UapWM L QiTiDaipj (1- exp( -}dTb ))

F ;

Where:

110000 = a constant that accounts for time and flow conversions Rapj =the annual dose to organ j (including the total body), through pathway p, to age group a Uap = the age dependent usage factor for the specific pathway. Usage factors for shoreline exposure are residence time on the shoreline (hours). Usage factors are provided in Reg. Guide 1.109 Table E-5. Usage factors specifically selected for Oyster Creek are presented in Table B-1.

W = the shore width factor. This adjusts the infinite. plane gamma or beta dose factors for. .

the finite size and shape of the shoreline. Different factors apply to different bodies of water. A factor of 0.1 is used for OC for 'discharge canal bank'.

M = the recirculation factor. The recirculation factor is a multiplier of 3. 76 to account for recirculation of discharge water back into the intake. Although this occurs infrequently, it is assumed to occur for each liquid release.

102015

CY-OC-170-301 Revision 7 Page 77 of 140 F = the flow rate in the discharge canal in cubic feet per second Qi = the activity of the ith isotope in the release in curies Ti = the half life of the ith isotope in days Daipj =the age a, isotope i, pathway p, and organ j, specific dose conversion factor.

Pathway, isotope, age, and organ specific dose factors are obtained from Regulatory Guide 1.109 Appendix E, Tables E-6 through E-14 Ai = the decay constant of the ith isotope in years Tb = the long term buildup time, assumed to be 30 years Note: Ai and Tb can use any time units as long as they are both the same. No transit delay (Tp from Reg. Guide 1.109) is assumed.

1.5.3 SHORELINE DOSE EXAMPLE 1 The following provides an example of the liquid dose calculation:

Initial parameters:

Canal flow rate 1E6 gpm (typical of normal full power operation)

Release: 10,000 gallons of water at 1E-3 µCi/ml Co-60 Problem: calculate shoreline whole body dose Uap = 67 (teenager) hours w =0.1 M = 3.76 F = 2228 [1E6 gpm *3785 ml I gal I (60 sec/min* 28316 ml/ft3) = 2228 CFS]

Qi = 0.03785 Ci [1E-3uCi/ml

10000gal

3785ml/gal / 1E6 uCi/Ci = 0.03785 Ci]

1.6 REPRESENTATIVE SAMPLES .

A sample should be representative of the bulk stream or volume of effluent from which it is taken. Prior to sampling, large volumes of liquid waste should be mixed in as short a time interval as practicable to assure that any sediments or particulate solids are distributed uniformly in the waste mixture. Recirculation pumps for liquid waste tanks (collection or sample test tanks) should be capable of recirculating at a rate of not less than two tank volumes in eight hours. Minimum recirculation times and methods of recirculation are controlled by specific plant procedures.

CY-OC-170-301 Revision 7 Page 81 of 140 2.0 GASEOUS EFFLUENTS 2.1 RADIATION MONITORING INSTRUMENTATION AND CONTROLS The gaseous effluent monitoring instrumentation and controls at Oyster Creek for controlling and monitoring normal radioactive material releases in accordance with the Radiological Effluent CONTROLS are summarized as follows:

(1) Main Stack The main stack receives normal ventilation flow from the reactor building, new radwaste, old radwaste, process discharge flow from the augmented off gas system (AOG), condenser off gas flow if AOG is not in service, and normal ventilation flow from portions of the turbine building, predominantly the condenser bay area. Reactor building and turbine building flow is not normally processed or filtered. Reactor Building flow may be manually or automatically directed through the Standby Gas Treatment System (SBGTS) which has particulate and charcoal filtration. Off gas flow is processed through AOG or through a 30-minute delay pipe prior to release. Flow from the 'new' and 'old' radwaste buildings is HEPA filtered. Releases through the main stack are monitored for noble gases using the RAGEMS I system and sampled for iodine, particulates and tritium. The plant stack is considered to be a true elevated release point.

(2) Turbine Building Vent The Turbine building vent is monitored for noble gases by the RAGEMS II system and sampled for iodine, particulates and tritium. It discharges on the west side of the turbine building approximately at roof height and is considered to be a ground level release. It*

ventilates the turbine floor and other areas of the turbine building. Flow through this release point is not filtered.

(3) Feed Pump Room Vent The feed pump room vent is monitored by RAGEMS II. It discharges on the east side of the turbine building below roof height and is considered to be a ground level release. It ventilates the reactor feed pump room. Flow through this release point is not filtered.

(4) Augmented Off Gas Building Vent Off gas Building HVAC is released through a ground level release from the building. Off Gas process flow is not released through the building ventilation, but is routed to the stack plant. A ventilation monitoring system monitors for noble gas and samples for particulate and iodine.

102015

CY-OC-170-301 Revision 7 Page 82 of 140 (5) Isolation Condensers The isolation condensers are a ground level release. The predominant isotope through this potential release point is tritium as a *consequence of the forced evaporation of condensate transfer water when the isolation condensers are initiated. Releases are neither monitored nor is the release process flow sampled. Releases of tritium are evaluated based on liquid samples of the input and the volume used.

Gaseous radioactive waste flow diagrams with the applicable, associated radiation monitoring instrumentation controls are presented in Figures D-2-1 and D-2-2.

2.2 GASEOUS EFFLUENT MONITOR SET POINT DETERMINATION 2.2.1 PLANT VENT Per the requirements of CONTROL 3.3.3.11, alarm set points shall be established for the gaseous effluent monitoring instrumentation to ensure that the release rate of noble gases does not exceed the limits of CONTROL 3.11.2.1, which corresponds to a dose rate at the SITE BOUNDARY of 500 mrem/year to the total body or 3000 mrem/year to the skin. Based on a grab sample analysis of the applicable release (i.e., of the Stack, Off gas process flow, etc.), the radiation monitoring alarm set points may be established by the following calculation methods. A set point of a monitor of an elevated release, e.g., from the stack, may be calculated using the equation:

S

( JL (CiDFSi) g f

Where:

s =the alarm set point (cpm) h = primary conversion factor of the instrument - monitor response to activity concentration of effluent being monitored, cpm/(µCi/cm 3 ). Each monitoring channel has a unique response, h, which is determined by the instrument calibration.

Ci = relative concentration of noble gas radionuclide i in effluent at the point of monitoring (µCi/cm 3) 1.06 = 500 mrem/year /472 (conversion of cfm to cc/sec)

DFSi = factor converting elevated release rate of radionuclide i to total body dose equivalent rate at the location of potential exposure. Units are: mrem/(yr(µCi/sec)).

From Table A-1.

f = flow of gaseous effluent stream being monitored, i.e., stack flow, vent flow, etc.

Q Where:

DFVi =factor converting ground-level or vent release of radionuclide i to the total body dose equivalent rate at the location of potential exposure. Units are: mrem-m 3/µCi-year From Table A-1.

XIQ =atmospheric dispersion from point of ground-level or vent release to the location of potential exposure (sec/m 3) from Table 2.2.2-1.

The atmospheric dispersion, X/Q, and the dose conversion factor, DFSi, depend upon local conditions. For the purpose of calculating radioactive noble gas effluent monitor alarm set points appropriate for the OCGS, the locations of maximum potential Off Site exposure and the reference atmospheric dispersion factors applicable to the derivation of set points are given in Table 2.2.2-1.

Symbols for this equation were defined in Section 2.2.1.

102015

CY-OC-170-301 Revision 7 Page 84 of 140 2.2.3.1 Preferably, the radionuclide distribution is obtained by gamma isotopic analysis of identifiable noble gases in effluent gas samples. Results of the analyses of one or more samples may be averaged to obtain a representative spectrum.

2.2.3.2 In the event a representative distribution is unobtainable from recent measurements by the radioactive gaseous waste sampling and analysis program, it may be based upon past measurements.

2.2.3.3 Alternatively, the total activity concentration of radioactive noble gases may* be assumed to be Xenon-133 as found in Reg Guide 1.97.

2.3 GASEOUS EFFLUENT INSTANTANEOUS DOSE RATE CALCULATIONS- 10 CFR 20 2.3.1 SITE BOUNDARY DOSE RATE - NOBLE GASES CONTROL 3.11.2.la limits the dose rate at the SITE BOUNDARY due to noble gas releases to ~ 500 mrem/yr, total body and ~ 3000 mrem/yr, skin. Radiation monitor alarm set points are established to ensure that these release limits are not exceeded.

In the event any gaseous releases from the station results in an alarm set point (as determined in Section 2.2) being exceeded, an evaluation of the SITE BOUNDARY dose rate resulting from the release shall be performed.

2.3.1.1 TOTAL BODY DOSE RATE The total body dose equivalent rate from radioactive noble gases discharged from an elevated point (stack *above building wake) is Galculated with the equation:

DG= LQiPySi i

From a ground-level release (building vent) the total body dose equivalent rate is:

DG = ~ LQiPyVi Qv ;

Where:

DG = total body dose equivalent rate due to irradiation by radioactive noble gas (mrem/hr)

A tabulation of these factors used to compute noble gas-to-dose equivalent rate at 338 meters ENE for ground-level or vent and 544 meters SE for stack from the OCGS is in Table A-2.

Evaluation of compliance with CONTROL 3.11 ~2.1 b is based on the sampling and analyses specified in TABLE 4.11.2.1.2-1.

Since the dose rate cannot be resolved within less than the sample integration or compositing time, the contribution of each radionuclide to the calculated dose rate will be averaged no more than 3 months for H-3, Sr-89, Sr-90, and alpha-emitting radionuclides and no more than 31 days for other radionuclides. These are their usual sample integration or compositing times. The equation used to assess compliance of radioiodine, tritium, and radioactive particulate releases with the dose rate limit is:

Noble gases may be released from the ground level vents and stack. The quantity of noble gas radionuclides released will be determined from the continuous noble gas monitors and periodic isotopic analyses. The maximum Off Site gamma radiation dose rate to air from noble gases discharged from either the stack or from building vents occurs at 805 meters SE of the OCGS for the stack and 338 meters ENE of the OCGS for building vents. Values of AySi depend upon the meteorological conditions and the location of exposure and are calculated using the NRC RABFIN code or similar one in accordance with Reg. Guide 1.109, Appendix B, Section 1. AyVi and ABi are derived from Reg. Guide.1.109, Table B-1 for a semi-infinite cloud, independent of meteorology or location. Values of AySi, AyVi and ABi used to calculate the noble gas radiation dose to air at 805 meters SE of the OCGS for the stack and 338 meters ENE of the OCGS for building vents are in Table A-3. Reference atmospheric dispersion from the OCGS to 805 meters SE for the stack and 338 meters ENE for building vents is given in Table 2.4.1.1-1.

The method for dose to an individual from noble gases is essentially identical with the qir dose method except that different dose factors apply. Also, since dose to the skin combines the contribution from gamma and beta emissions, the gamma dose must be added to the beta dose to obtain a total skin dose.

CY-OC-170-301 Revision 7 Page 93 of 140 2.5 RADIOIODINE, PARTICULATE AND OTHER RADIONUCLIDES DOSE CALCULATIONS - 10 CFR 50 Doses resulting from the release of radioiodines and particulates must be calculated to show compliance with Appendix I of 10CFR50. Calculations will be performed at least monthly for all gaseous effluents as stated in SURVEILLANCE REQUIREMENT 4.11.2.2 and SURVEILLANCE REQUIREMENT 4.11.2.3 to verify that the dose to air is kept below the limits specified in CONTROL 3.11.2.2 and the dose to MEMBERS OF THE PUBLIC is maintained below the limits specified in CONTROL 3.11.2.3.

The maximum dose to an individual from radioiodines, tritium, and radioactive particulates with half-lives of greater than eight days in gase*ous effluents released to unrestricted areas is determined as described in Reg. Guide 1.109. Environmental pathways that radioiodine, tritium, and particulates in airborne effluent follow to the maximally exposed MEMBER OF THE PUBLIC as determined by the annual land use survey and reference meteorology will be evaluated. The seasonality of exposure pathways may be considered. For instance, if the most exposed receptor has a garden, fresh and stored vegetables are assumed to be harvested and eaten during April through October. Fresh vegetables need not be considered as an exposure pathway during November through March. To assess compliance with CONTROL 3.11.2.3, the dose due to radioactive iodine, tritium, and particulates in airborne effluent is calculated to a person residing 972 meters ESE of the OCGS for ground-level or vent and 937 meters SE of the OCGS for stack. Reference atmospheric dispersion and deposition factors are given in Table 2.5-1.

Ground Level or Vent 5.13 E-6 1.68 E-8 Stack 1.25 E-8 2.39 E-9 The environmental pathways of exposure to be evaluated are: inhalation, irradiation from ground deposition, and ingestion of milk (cow and goat are treated separately), meat, and vegetables. Eight organs are considered: Bone, Liver, Total Body, Thyroid, Kidney, Lung, Gl-LLI (Gastro-lntestinal tract I Lower Large Intestine), and Skin. Four different age groups are considered: Infants, Children, Teens, and Adults. Doses are calculated to a 'receptor' - a person who inhales the airborne activity and resides in a location with ground deposition, and eats and drinks the foodstuffs produced. The maximally exposed individual is conservatively assumed to reside at the location of the highest sum of the inhalation and ground plane doses, while eating and drinking foodstuffs transported from the locations that are highest for those pathways. Receptor locations are provided in TableA-4.

Alternatively, an approved computer code (e.g., "SEEDS" or "Open EMS") that implements the requirements of Reg Guide 1.109 may be used.

Dose from the inhalation pathway is generally in the form:

Dja = RaTL ~iDFAijaExp(-}dTr) iQ Where:

Oja =the dose to the organ j (of eight) of age group a (of four)

Ra =the respiration rate for age group a from Table B-1 T = the duration of the release in fraction of a year x = The atmospheric dispersion to the point of interest (the 'receptor') in sec/m 3 from Q

Ai =decay constant of isotope i: 0.693/ Half life in years Tr = plume transit time from release to receptor in years Ai and Tr may be in any time units as long as they are the same Note that a 'depleted X/Q' (dX/Q) is applicable to particulates only, which accounts for the natural settling and lack of surface reflection of particulates to estimate the downwind concentration accounting for these removal processes. Depleted X/Q will be slightly smaller than the X/Q. This is not used in the ODCM for simplicity. Using the X/Q is therefore slightly conservative compared to the dX/Q.

2.5.3.1 CONCENTRATION OF THE RADIONUCLIDE IN ANIMAL FORAGE AND VEGETATION - OTHER THAN TRITIUM The concentration of a radionuclide in a foodstuff (other than tritium - see section 2.5.3.3 for tritium) is dependent on the atmospheric deposition, the biological uptake into the food, various decay times (plume travel, harvest to tablei etc.) and is generally of the form:

Further; the concentration of tritium in food is assumed to be based on equilibrium between the concentration of the tritium in the atmospheric water and the concentration of tritium in the water in the food. Concentration of tritium in vegetation can be calculated generally in the form (a plume transit decay term: EXP(-A-iTr) is ignored since plume travel times are very short compared to the half life):*

Ctv = lOOOQt X

5 Ctv = 1.07 pCil kg 2.5.3.5 CONCENTRATION OF THE RADIONUCLIDE IN MILK AND MEAT Meat and milk animals are assumed to eat both pasture grass and stored feed. During a fraction of the year, they may be assumed to be exclusively on stored feed, outside of the growing season. If using annual average release, the fraction of stored and fresh feed must be accounted for with fractions, otherwise (as in this ODCM), the fresh pasture pathway is turned on or off depending on the growing season.

The concentration of a radionuclide in the animal feed is calculated as follows:

Civ = FpCis+ (l-Fp)Cis(l-Fs) + CipFs(l-Fp)

Where:

Fp =the growing season pasture factor: 1 if not growing season, 0 if in growing season 102015

CY-OC-170-301 Revision 7 Page 99 of 140 Fs =the fraction of the daily feed from fresh pasture from Table 8-1 or Exhibit E-15 from Reg. Guide 1.109.

Cip = the concentration in the fresh pasture feed (Civ from section 2.5.3.2 with Th = 0 for immediate consumption)

Cis = the concentration in stored feed (Civ from section 2.5.3.2 with Th = 90 days)

The concentration in the milk is then based on this feed concentration:

Cim = FmCivQ/EXP (-}dTf)

Where:

Cim = the concentration in milk pCi/I Fm =the transfer coefficient of intake to concentration in the milk (d/I) from Reg. Guide 1.109 Table E-1.

Qf =feed intake rate Kg/d from Reg. Guide 1.109 Table E-3.

A.i =radionuclide i decay constant in 1/days Tf = transport time from milk production to consumption (2 days for milk)

The Goat milk pathway may be similarly evaluated:

Cim = FgCivQ/EXP (-A,iTf)

Where:

Fg =the transfer coefficient of intake to concentration in the milk (d/I) for goats from Reg. Guide 1.109 Table E-2.

And for meat:

Cif = FfCivQ/EXP (-1iTs)

Where:

Ff =the transfer coefficient of intake to concentration in the meat d/kg from Reg.

Ts =the transport time from slaughter to consumption (20 days) 102015

Plume transit decay time is ignored (exp{-A.iTr)=1):-

Civ = FpCis + (1- Fp )Cis(l - Fs) + CipFs(l - Fp)

Assume animals are on pasture and receive half of their food from stored feed.

Cip = 18.0 pCi/kg as previously calculated in section 2.5.3.2 Fp = 0 .

There are two separate pathways for vegetation: fresh leafy vegetables and a combination of fruits, non-leafy vegetables, and grains. These differ only in the decay and buildup processes applied to account for the environmental exposure, and transportation delay decay represented by Te and Th as shown in section 2.5.3.1. For long half-life isotopes (e.g. Co-60) the decay differences have little impact on the dose.

Dose from the environmental ingestion pathways is generally of the form:

Dja = TLDFiijc{_UavFgCiv+ UamCim + Ua/Cif + UalF/Cil]

i Where:

Dja = the dose to organ j of age group a - mrem T = fraction of year of release duration DFlija =the ingestion dose factor for isotope i to organ j for age group a - mrem/pCi from Reg.

CY-OC-170 ..301 Revision 7 Page 105of140 sources (including dose contributions from effluents and direct radiation from on-site sources). For the likely most exposed MEMBER OF THE PUBLIC in the vicinity of Oyster Creek, the sources of exposure need only consider the Oyster Creek Generating Station.

No other fuel cycle facilities would contribute significantly to the MEMBER OF THE PUBLIC dose for the Oyster Creek vicinity, however, both plant operation and ISFSI sources must be included in the dose assessment.

To assess compliance with CONTROL 3.11.4, calculated organ and total body doses from effluents from liquid pathways and atmospheric releases as well as any dose from direct radiation will be summed.

As appropriate for demonstrating/evaluating compliance with the limits of CONTROL 3.11.4 (40 CFR 190), the results of the environmental monitoring program may be used for providing data on actual measured levels of radiation and I or radioactive material and resultant dose to the MEMBER OF THE PUBLIC in the actual pathways of exposure.

3.1 EFFLUENT DOSE CALCULATIONS For purposes of implementing the surveillance requirements of CONTROL 3/4.11.4 and the reporting requirements of Technical Specification 6.9.1.d (ARERR), dose calculations for the Oyster Creek Generating Station may be performed using the calculation methods contained within the ODCM; the conservative controlling pathways and locations from the ODCM or the actual pathways and locations as identified by the land use census (CONTROL 3/4.12.1) may be used. Average annual meteorological dispersion parameters provided herein or meteorological conditions concurrent with the release period under evaluation may be used.

3.2 DIRECT EXPOSURE DOSE DETERMINATION Any potentially significant direct exposure contribution to off-site individual doses may be evaluated based on the results of environmental measurements (e.g., dosimeter) and/or by the use of radiation transport and shielding calculation methodologies.

4.0 RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM The operational phase of the Radiological Environmental Monitoring Program (REMP) is conducted in accordance with the requirements of CONTROL 3.12.1. The objectives of the program are:

- To determine whether any significant increases occur in the concentration of radionuclides in the critical pathways of exposure in the vicinity of Oyster Creek

- To determine if the operation of the Oyster Creek Generating Station has resulted in any increase in the inventory of long lived radionuclides in the environment;

- To detect any changes in the ambient gamma radiation levels; and

- To verify that OCGS operations have no detrimental effects on the health and safety of the public or on the environment.

The REMP sample locations are presented in Appendix E.

The nearby resident (part-time) experiencing the maximum exposure to gamma radiation directly from the Station is located 618 meters WSW of the OCGS. The most exposed member of the public is assumed to be exposed by irradiation from the OCGS, by inhaling airborne effluent, by irradiation by the airborne effluent, by irradiation by the airborne plume of the noble gas, by radionuclides deposited onto the ground, by irradiation by shoreline deposits, and by eating fish and shellfish caught in the discharge canal.

The age group of the most exposed member of the public is based on Reg. Guide 1.109, Revision 1.

Oyster Creek 2015 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 mon itoring .

Both radiological environmental and effluent monitoring indicate that the operation of Oyster Creek Generating Station (OCGS) does not result in significant rad iation 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 2015 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 277 days in 2015. The nearly continuous releases occurred from January 1, 2015 through January 30 , 2015 and April 27 , 2015 through December 31 , 2015 with a total of 2.78E+07 gallons of groundwater pumped resulting in 2.08E-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 9.86E-07 mrem.

There were no liquid abnormal releases during 2015.

There were no gaseous abnormal releases during 2015.

The maximum calculated organ dose (Bone) from iodines, tritium , carbon-14 (C-14) , and particulates to any individual due to gaseous effluents was 5.53E-01 mrem, which was approximately 3.69E+OO 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 4.86E-03 mrad, which was 4.86E-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 620 mrem per year to the average person in the United States.

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 2015. Because it is a sealed unit, no radioactive material was released .

Oyster Creek 2015 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 4.30E-03 Ci and total particulates with half-lives greater than 8 days less C-14 released of 2.69E-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 99.8 percent and 99.8 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.

Oyster Creek 2015 Annual Radioactive Effluent Release Report 1 Sources of Radiation Dose to the U.S . Population Note: The information in th is section is from the following NRC report: Radioactive Effluents from Nuclear Power Plants: Annual Report 2007 For comparison with Nuclear Power Plant (NPP) effluents, this section provides a perspective on the doses that Americans typically receive on average from natural and background rad iation.

In March 2009, the National Council on Radiation Protection and Measurements (NCRP) published Report No. 160 as an update to the 1987 NCRP Report No. 93, Ionizing Radiation Exposure of the Population of the United States (Refs. 28 , 29) . Report No. 160 describes the doses to the U.S. population from all sources of ionizing radiation for 2006 , the most recent data available at the time the report was written . The report also includes information on the variability of those doses from one individual to another. The NCRP estimated that the average person in the United States receives the equivalent of about 620 mrem of radiation dose each year. NCRP Report No. 160 describes each of the sources of radiation that contribute to this dose, including:

1. naturally-occurring sources (natural background ) such as cosmic rad iation from space, terrestrial radiation from rad ioactive materials in the earth , and naturally occurring radioactive materials in food people eat and air people breathe;

2. medical sources from diagnosis and treatment of health disorders using radioactive pharmaceuticals and radiation-producing equipment;

3. consumer products;

4. industrial processes, security devices, educational tools, and research activities;

5. exposures of workers that result from their occupations .

Figure 1.1 is a pie chart showing the relative contributions of these sources to radiation dose to the U.S. popu lation . Larger relative contri butors to dose are represented by proportionally larger sl ices of the pie . Doses to the publ ic from nuclear power generation are included in the industrial category ; doses to workers from nuclear power generation are included in the category of occupational dose.

Doses to the public due to effluents from NPPs are less than 0.1% of what the average person receives each year from all sources of radiation. Doses to workers from occupational exposures, including those received from work at NPPs, also are less than 0.1% of the average dose to a member of the public from all sources.

Oyster Creek 2015 Annual Radioactive Effluent Release Report 2 Exposure Pathways Radiological exposure pathways define the methods by which people may become exposed to radioactive material. The major pathways of concern are those which could cause the highest calculated radiation dose. These projected pathways are determined from the type and amount of radioactive material released , the environmental transport mechanism, and the use of the environment. The environmental transport mechanism includes consideration of physical factors, such as the hydrological (water) and meteorological (weather) characteristics of the area. An annual average of the water flow , wind speed , and wind direction are used to evaluate how the radionuclides will be distributed in an area for gaseous or liquid releases. An important factor in evaluating the exposure pathways is the use of the environment.

Many factors are considered such as dietary intake of residents, recreational use of the area , and the locations of homes and farms in the area.

The external and internal exposure pathways considered are shown in Figure 2.1. The release of radioactive gaseous effluents involves pathways such as external whole body exposure , deposition of radioactive material on plants, deposition on soil ,

inhalation by animals destined for human consumption , and inhalation by humans.

The release of radioactive material in liquid effluents involves pathways such as drinking water, fish , and direct exposure from the water at the shoreline while swimming .

Although radionuclides can reach humans by many different pathways, some result in more dose than others. The critical pathway is the exposure route that will provide, for a specific radionuclide , the greatest dose to a population, or to a specific group of the population called the critical group. The critical group may vary depending on the radionuclides involved , the age and diet of the group, or other cultural factors . The dose may be delivered to the whole body or to a specific organ . The organ receiving the greatest fraction of the dose is called the critical organ .

Oyster Creek 2015 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 µCi/ml.

C. Average Energy ( 'E ) :

Ihe 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 accord~nce with ODCM Table 4.11.2.1.2-1.

Charcoal samples are taken from the stack RAGEMS sample point and 9

Oyster Creek 2015 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 r~move 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, 1-129, Ni-59, Ni-63, Tc-99, Am-241, Cm-242, Cm-243/244, Pu-238, Pu-239/240 and Pu-241.

Fe-55 and Ni-63 have been added to the routine monthly composite analysis schedule based on previous sample results for Hard-To-Detects. Only nuclides that have been detected are included in Table A-2 and/or Table A-3.

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 5.27E-01 mrem to the bone.

8. Liquid Effluents Groundwater containing tritium was released during 2015. For continuous releases, tritium and principal gamma emitters were determined fbr 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 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 the amount of activity discharge is accurate and limiting, the activity and doses as a result of discharges during 2015 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:

G. Revisions to the ODCM:

Revision 7 of the ODCM, CY-OC-170-301 was implemented 10/22/2015. A list of the major changes is included below. See the complete copy of CY-OC-170-301 Revision 7 attached as part of this report.

Changed description of REMP Sample Station 9 from SW to WSW - Note, sample location was correct on Figure E-2.

Changed description of REMP Sample Stations 106 and 107 from NW to WNW - Note, sample location was correct on Figure E-2.

Changed REMP Sample Station 3 from an airborne background location to

(

an airborne special interest location which was listed in error as a background location in the last revision.

Added REMP Sample Station 114 back into the REMP since it was accidently left off the list as a drinking water sample location in the last revision - Note, sample location 114 was still listed on Figure E-1 in the last revision.

Removed REMP Sample Station 39 from the REMP in the list as a background drinking water sample location and from Figure E-2.

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 13

Oyster Creek 2015 Annual Radioactive Effluent Release Report 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. There was no instrumentation out of service for greater than 30 days.

I. Releases from the Independent Spent Fuel Storage FaaiJity~

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 2015. Because it is a sealed unit, no radioactive material was released.

J. Program Deviations:

1. There were no program deviations in 2015.
