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, qual i ty assurance programs for the effluent and environmental programs , and procedures covering all aspects of effluent and environmental monitoring. Both radiological environmental and effluent monitoring indicate that the operation of Oyster Creek Generating Station (OCGS) does not result in significant radiation exposure to the people or the environment surrounding OCGS and is well below the applicable levels set by the Nuclear Regulatory Commission (NRC) and the Environmental Protection Agency (EPA). There were liquid radioactive effluent releases during 2017 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 60 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 303 days in 2017. The nearly continuous releases occurred from January 1 , 2017 through October 5 , 2017 and December 12, 2017 through December 31, 2017 with a total of 2.85E+07 gallons of groundwater pumped resulting in 2.17E-01 Ci of tritium released to the discharge canal. The dose to the most limiting member of the public due to the release of groundwater was 1.02E-06 mrem. There were no liquid abnormal releases during 2017. There were no gaseous abnormal releases during 2017. The maximum calculated organ dose (Bone) from iodines, tritium , carbon-14 (C-14), and particulates to any individual due to gaseous effluents was 5.39E-01 mrem, which was approximately 3.59E+OO percent of the annual limit of 1.50E+01 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 5.86E-04 mrad , which was 5.86E-03 percent of the annual 10 CFR 50 Appendix I , As Low As Reasonably Achievable (ALARA) limit of 1.00E+01 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 2017. Because it is a sealed unit , no radioactive material was released. 1 Oyster Creek 2017 Annual Radioactive Effluent Release Report Comparison of environmental sampl i ng results to iodine and part i culate gaseous effluents released , showed no rad i oactivity attr i butable to the operat i on of OCGS. Both elevated and ground-l evel release paths were cons i dered in this review , with total i odines released of 8.06E-03 Ci and total part i culates with half-lives greater than 8 days of 1.50E-02 Ci. This total does not include C-14 , wh i ch is calcu l ated separately. I t was calcu l ated that 9.63EOO Ci of C-14 were released i n 2017. Joint Frequency Tables of meteorological data , per Stability Classification Category , as well as for all stability classes , are i ncluded. 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 bas i s. 2 Oyster Creek 2017 Annual Radioactive Effluent Release Report The nuclear power industry uses terms and concepts that may be unfamiliar to all readers of this report. This section of the report is intended to help the reader better understand some of these terms and concepts. In this section , we will discuss radiation and exposure pathways. This section is intended only to give a basic understanding of these subjects to hopefully allow the reader to better understand the data provided within the report. Every nuclear power station i s required to submit two reports annually , the Annual Radioactive Effluents Release Report (ARERR) and the Annual Radiological Environmental Operating Report (AREOR). The following information is provided in both reports for Oyster Creek Generating Station. 1. Understanding Radiation Radiation is simply defined as the process of emitting radiant energy in the form of waves or particles. Radiation can be categorized as ionizing or non-ionizing radiation. If the radiation has enough energy to displace electrons from an atom it is termed ionizing radiation. Typically you will see a warning sign where there is a potential to be exposed to man-made ionizing radiation.

These signs normally have the trefoil symbol on a yellow background. emmJ.ail RADIOACTIVE

MATERIALS.

Example Radiological warning signs People do not always recognize non-ioniz i ng radiation as a form of radiation , such as light , heat given off from a stove , radiowaves and microwaves. In our report we focus on the ionizing radiation that is produced at a nuclear power plant though it is important to note that ionizing radiation comes from many sources. In fact , the amount of ionizing radiation an average person is exposed to due to operation of a nuclear power plant is a very small fraction of the total ionizing rad i ation they will be exposed to in their lifetime and will be discussed later. From this point forward we will only be discussing ionizing radiation but we will just use the term radiation. Since this report discusses radiation in different forms and different pathways we first need to understand where the radiation comes from that we report. Radiation comes from atoms. So , what are atoms and how does radiation come from atoms? 3 Oyster Creek 2017 Annual Radioactive Effluent Release Report You may have seen a Periodic Table of the Elements Group-1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 !Period The Periodic Table of the Elements 1 2 1 He 2 I :e I []~ Ne 3 [Ml g [illrn] Ar 4 ,~, rnJ[ID Kr 5 [ID CT]~ Xe 6 I ~:1 [fil[g] Rn 7 a Fl Mc Lv Ts Og Lanthanldes Actinides This table lists all the elements found on earth. An atom is the smallest part of an element that maintains the characteristics of that element. An atom is made up of three parts , protons, neutrons and electrons.

Electron The number of protons in an atom determines the element. A hydrogen atom will always have one proton while an oxygen atom will always have eight protons. The protons are cluste r ed 4 Oyster Creek 2017 Annual Radioactive Effluent Release Report w i th the neutrons at the center of the atom and this i s called the nucleus. Orbiting around the nucleus are the relatively small electrons. Neutrons do not have an electrical charge , protons have a posit i ve charge wh i le electrons have a negat i ve charge. In an electrically neutral atom , t he negative and pos i tive charges are balanced. Atoms of the same element that have a different number of neutrons in their nucleus are called isotopes.

Isotopes are atoms that have the same number of protons but different number of neutrons. They all have the same chemical properties and many isotopes are nonradioactive or stable while other isotopes may be unstable and are radioact i ve. Radioact i ve isotopes can be called a radionuclide , a radioisotope or simply called a radioactive atom. A radionuclide usually contains an excess amount of energy in the nucleus usually due to a defic i t or excess of neutrons in the nucleus. There are two basic ways radionuclides are produced at a nuclear power plant. The first way is a direct result of the fiss i on process and the radionucl i des created through this process are termed fission products. Fission occurs when a very large atom , such as U-235 (Uranium-235) and Pu-239 (Plutonium-239) absorbs a neutron i nto its nucleus making the atom unstable. In th i s instance the atom can actually split into smaller atoms. Th i s splitting of the atom is called fission. When fission occurs there i s also a large amount of energy released from the atom in the form of heat which i s what is used to produce the steam that w i ll spin the turbines to produce electricity at a nuclear power plant. The second way a radionuclide is produced at a nuclear power p l ant is through a process called act i vation and the radionuclides produced in this method a r e termed activation products.

Water passes through the core where the fission process is occurring. This water is used to both produce the steam to turn the turbines and to cool the reacto r. Though the water passing through the core is considered to be very pure water , there is always some other material with i n the water. This material typically comes from the material used in the plant's construction. As the water passes through the core , the mater i al i s exposed to the fission process and the radiation within the core can react with the material causing i t to become unstable , creating a radionuclide. The atoms in the water itself can become activated and c r eate rad i onucl i des. Over time , rad i oactive atoms will reach a stable state and no longer be radioact i ve. To do this they must release the excess energy. The release of excess energy can be in different forms and is called r adioactive decay and the energy released is called radiation. The t i me it takes for a radionuclide to become stable is measured in un i ts called half-l i ves. A half-l i fe is the amount of time i t takes for half of the o ri g i nal radioactivity to decay. Each r ad i onuclide has a specific half-l i fe. Some half-lives can be very long and are measured in years while others may be very short and are measured in seconds. 5 Oyster Creek 2017 Annual Radioactive Effluent Release Report 1000 8(XJ Activity li<Xl 200 0 1 half-life Half-life 2 half-lives The amount of time i t takes for ha l f of the orig i na l radioactivity to decay 3 half-lives 4 half-lives In this report you will see radionuclides listed such as K-40 (potassium-40) and Co-60 (cobalt-60). The letter(s) represents the element and the number represents the spec i fic isotope of that element and is the number of nuetrons in the nucleus of that radionuclide.

You may hear the term naturally occurring radionuclide which refers to radionuclides that naturally occu r in nature such as K-40. There are man-made radionuclides such as Co-60 that we are concerned with since these man-made radionuclides result as a by-product when generating electricity at a nuclear power plant. There are other ways man-made radionuclides are produced , such as detonating nuclear weapons , and this is important to note since nuclear weapons testing deposited these man-made radionuclides into the environment and some are still present today. There is a discussion in the AREOR for the rad i onculides Cs-137 , Sr-89 and Sr-90. The reason we only see some of the radionuclides today is due to the fact that some of the radionuclides released into the environment had relatively short half-lives and all the atoms have decayed to a stable state while other radionuclides have relatively long half-lives and will be measururable in the environment for years to come. 6 Oyster Creek 2017 Annual Radioactive Effluent Release Report 2. Sources of Radiation People are exposed to radiation every day of their lives and have been since the dawn of mankind. Some of this radiation is naturally occurring while some is man-made. There are many factors that will determ i ne the amount of radiation an individual will be exposed to such as where you live , medical treatments, etc. Below are examples of some of the typical sources of radiation an individual is exposed to in a year.

.org As you can see from the graph, the largest natural source of radiation is due to Radon. That is because essentially all air contains Radon. Cosmic and Internal make up the next largest natural sources of radiation. Cosmic radiation comes from the sun and stars and there are multiple factors which can impact the amount of cosmic radiation you are exposed to such as the elevation at which you l i ve and the amount of air travel you take a year. The internal natural source of radiation mainly comes from two sources. Technically, all organic material is slightly radioactive due to C-14 (Carbon-14), including humans and the food we eat. C-14 makes up a percentage of the carbon in all organic material.

Another contributor to the internal natural source is K-40 (Potassium-40). Potassium is present in many of the foods we eat, such as brazil nuts, bananas, carrots and red meat. The smallest natural source listed is terrestrial.

Soil and rocks contain radioactive materials such as Radium and Uranium. The amount of terrestrial radiation you are exposed to depends on where you live. The map below shows terrestrial exposure levels across the United States. The radiation released from nuclear power plants is included in the Industrial and Occupational slice and is listed as <0.1 %. 7 Oyster Creek 2017 Annual Radioactive Effluent Release Report Terrest r ial Gamma-Ray Exposu r e at 1m above ground 2.5 al Rlhr 3. Exposure Pathways S o urce oo da ta: U.S. Ge olC,1 i c;a l S u NeyDi g ila l De l a Series OOS-9. 1 993 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 into the environment and how the environment is used. T he way radioactive material is transported in the environment 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 o f 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-bo d y 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. 8 Oyster Creek 2017 Annual Radioactive Effluent Release Report 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 g r oup of the population called the critical group. The crit i ca l group may vary depending on the radionuclides i nvolved , 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 o r gan receiving the greatest fraction of the dose i s called the critica l organ.

Radiation Risk U.S. radiation protection standards are based on the premise that any radiation exposure carries some risk. There is a risk whether the radiation exposure i s due to man-made sources or natural sources. There have been many studies performed trying to determine the level of ri sk. The following graph is an example of one study that tries to relate r i sk from many different factors. This graph represents risk as " Days of Lost Life Expectancy

". All the categories are averaged over the entire population except Male Smokers , Female Smokers and ind i viduals 9 Oyster Creek 2017 Annual Radioactive Effluent Release Report that are overweight.

Those risks are only for people that fall into those categories. The category for Nuclear Power is a government estimate based on all radioactivity releases from nuclear power , including accidents and wastes. Srioking -Male Heart Disease Smd<ini;;

.pdf 10 Oyster Creek 2017 Annual Radioactive Effluent Release Report 5. Annual Reports All nuclear power plants are required to perform sampling of both the potential release paths from the plant and the potential exposure pathways in the environment.

The results of this sampling are required to be reported annually to the Nuclear Regulatory Commission (NRC) and made available to the public. There are two reports generated annually , the Annual Radioactive Effluents Release Report (ARERR) and the Annual Radiological Environmental Operating Report (ARE OR). The AR ERR summarizes all of the effluents released from the plant and quantifies the doses to the public from these effluents. The AREOR summarizes the results of the samples obtained in the environment looking at all the potential exposure pathways by sampling different media such as air, vegetation , direct radiation, etc. These two reports are related in that the results should be aligned. The AREOR should validate that the effluent program is accurate. The ARERR and AREOR together ensure Nuclear Power Plants are operating in a manner that adequately protects the public. In the reports there are four different but interrelated units for measuring radioactivity , exposure, absorbed dose, and dose equivalent.

Together, they are used to properly capture both the amount of radiation and its effects on humans.

Radioactivity refers to the amount of ionizing radiation released by a material.

The units of measure for radioactivity used within the AREOR and ARERR are the curie (Ci). Small fractions of the Ci often have a prefix , such as µCi that means 1/1 , 000 , 000. That means there are 1 , 000 , 000 µCi in one Ci.

Exposure describes the amount of radiation traveling through the air. The units of measure for exposure used within the AREOR and ARERR are the roentgen (R). Traditionally direct radiation mon i tors placed around the site are measured in milliroentgen (mR), 1/1,000 of one R.

Absorbed dose describes the amount of radiation absorbed by an object or person. The units of measure for absorbed dose used within the AREOR and ARERR are the rad. Noble gas air doses are reported by the site are measured in milliard (mrad), 1/1 , 000 of one rad.

Dose equivalent (or effective dose) combines the amount of radiation absorbed and the health effects of that type of radiation. The units used within the ARE OR and AR ERR are the roentgen equivalent man (rem). Regulations require doses to the whole body , specific organ , and direct radiation to be reported in millirem (mrem), 1 /1,000 of one rem. 11 Oyster Creek 2017 Annual Radioactive Effluent Release Report Typically releases from nuclear power plants are so low that the samples taken in the environment are below the detection levels required to be met by all nuclear power plants. There are some radionuclides identified in the environment during the routine sampling but this is typically background radiat i on from nuclear weapons testing and events such as Chernobyl and these radionuclides are discussed in the AREOR. Each report lists the types of samples that are collected and the analyses performed.

Different types of media may be used at one sample location looking for specific radionuclides. For example, at our gaseous effluent release points we use different media to collect samples for particulates, iodines , noble gases and tritium. There are also examples where a sample collected on one media is analyzed differently depending on the radionuclide for which the sample is being analyzed.

These annual reports, and much more informat i on related to nuclear power , are available on the NRC website at www.nrc.gov. 12 l Oyster Creek 2017 Annual Radioactive Effluent Release Report 6.

Effluent Concent r ation Limits: Gaseous dose rates rather than effluent concentrat i ons are used to calculate perm i ssible release rates for gaseous releases. The maximum pe r m i ssible dose rates for gaseous releases are defined in ODCM Controls 3.11.2.1. The Effluent Concentration Li mit (ECL) specified in 1 0 CFR 20 , Appendix B , Tab l e 2 , Column 2 for i dentified nuclides , were used to calculate permissible release rates and concentrations for liquid release per ODCM Controls 3.11.1.1. The total act i vity concentration at the Route 9 bridge for all dissolved or entrained gases was limited to < 2E-04 µCi/ml. C. Average Energy ( E ) : The Oyster Creek ODCM limits the instantaneous dose equivalent rates due to the release of noble gases to less than or equal to 500 mrem/year to the total body and less than or equal to 3000 mrem/year to the skin. The average beta and gamma energies (E) of the radionucl i de 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 Re l eases of Reactor Effluents for the Purpose of Evaluating Compl i ance with 1 O 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 Approx i mat i ons of Total Rad i oact i v i ty: 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 S i te Dose Calculation Manual (ODCM) Table 4.1 1.2. 1.2-1. Additional grab samples were taken from the stack Radioactive and Gaseous Effluent Monitoring System (RAGEMS) samp l e point and ground-level release sample points and analyzed at least monthly to determ i ne the isotop i c mixture of noble gas activ i ty r eleased for the month. If activ i ty was found in the grab isotop i c analysis , the results are entered into Simplified Environmental Effluent Dosimetry System (SEEDS) to calculate dose and dose rates. If no activity is detected in the stack grab samples , post treatment or Off Gas Isotopic Analysis data may be used. / 2. Iodines The method used for Gamma Isotopic Analysis is the Canberra Gamma Spectroscopy System with a charcoal cartridge. Iodine activity was continuously sampled and analyzed in accordance with ODCM Table 4.11.2.1.2-1. Charcoal samples are taken from the stack RAGEMS sample point and 15 Oyster Creek 2017 Annual Radioactive Effluent Release Report ground-level release sample points and analyzed at least weekly to determine the total act i vity released from the plant based on the average vent flow rates recorded for the sampling per i od. 3. Particulates (half-l i ves > 8 days) The method used for Gamma Isotopic Analysis is t he Canberra Gamma Spectroscopy System with a particulate filter (47 mm). Particulate activity was continuously sampled and analyzed in accordance with ODCM Table 4.11.2.1.2-1. Particulate samples are taken from the stack RAGEMS sample point and ground-level release sample points and analyzed at least weekly to determine the total activity released from the plant based on the average vent flow rates recorded for the sampling period. 4. Tritium A. Gaseous Effluents Air from stack and vent effluents was passed through a desiccant column and distilled to remove the moisture collected. An aliquot of the water from the distillate was analyzed for trit i um 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 measu r ed 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 , 1-1 29 , 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 rou t ine monthly compos i te analys i s schedule based on prev i ous sample results for Detects. Only nuclides that have been detected are inc l uded i n Tab l e A-2 and/or Table A-3. 16 Oyster Creek 2017 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 dur i ng 2017. For continuous releases, tritium and principal gamma emitters were determined for a composite sample daily. The concentration of tritium is limited to ensure concentrations were less than 200 pCi/1 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 2017 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. 17 Oyster Creek 2017 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: Liquid: Principal Gamma Emitters (Mn-54, Fe-59, Co-58 , Co-60 , Zn-65 , Mo-99 , 1-131 , Ce-141, Cs-134 , Cs-137) Principal Gamma Emitters (Ce-144) Dissolved and Entrained Gases H-3 Gross Alpha Sr-89 and Sr-90 Fe-55 and Ni-63 Airborne Principal Gamma Emitters (Kr-87 , Kr-88, Xe-133, Xe-133m , Xe-135 , Xe-138) H-3 1-131 1-133 Principal Gamma Emitters (Mn-54, Fe-59 , Co-58, Co-60 , Zn-65, Cs-134 , Cs-137, Ce-141) Principal Gamma Emitters (Mo-99, Ce-144) Gross Alpha Sr-89, Sr-90 18 LLD SE-07 µCi/ml SE-06 µCi/ml 1 E-05 µCi/ml 1 E-05 µC i/ml 1 E-07 µCi/ml SE-08 µCi/ml 1 E-06 µCi/ml LLD 1 E-04 µCi/ml 1 E-06 µCi/ml 1 E-12 µCi/ml 1E-10 µCi/ml 1 E-11 µCi/ml 1 E-10 µCi/ml 1 E-11 µCi/ml 1 E-11 µCi/ml Oyster Creek 2017 Annual Radioactive Effluent Release Report E. Batch Releases: 1. Liquid There were no batch releases of liquid effluents during 2017. 2. Gaseous There were no batch releases of gaseous effluents during 2017. F. Abnormal Releases: There were no abnormal liquid releases during 2017. There were no abnormal gaseous releases during 2017. G. Revisions to the ODCM: There were no revisions to the ODCM in 2017. 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 liqu i d/gaseous effluent monitoring instrumentation channels OPERABLE , take the ACTION shown in Table 3.3.3.10-1/3

.3.3.11-1. Make every reasonable effort to return the instrument to OPERABLE status within 30 days and , if unsuccessful , explain in the next Radioactive Effluent Release Report why the inoperability was not corrected in a timely manner. The following is a discussion of instrumentation out of service for greater than 30 days: 1. The Turbine Building Ventilation Monitoring Radioactive Noble Gas Monitor (Low Range) was declared inoperable from December 24 , 2016 through March 24, 2017 (90 days). The system was originally declared inoperable to perform the Turbine Building RAGEMS Noble Gas Calibration surveillance and compensatory sampling was initiated per the ODCM. During the surveillance , the noble gas low range monitor failed the source check. The issue was entered into the Corrective Action Program and the low range monitor remained inoperable until the surveillance could be completed satisfactorily.

The failure was determined to be due to the age of the source being used to perform the surveillance.

The source had decayed to the point where it no longer had an activity level appropriate for this source check. A new source was ordered and the surveillance was revised for using the new source. The surveillance was completed satisfactorily with the new source. The time it took to order and obtain the new source as well as revise and reperform the 19 Oyster Creek 2017 Annual Radioactive Effluent Release Report surveillance resulted in the monitoring system being inoperable for more than 30 days. I. Releases from the Independent Spent Fuel Storage Fac i l i ty: The ISFSI is a closed system and the only exposure would be due to direct radiat i on. This i ncludes iodines , particulates , and noble gases. Based on offs i te TLD readings , dose due to direct radiation from the ISFSI was less than 1 mrem for 2017. Because it is a sealed unit , no radioactive mater i al was released. J. Prog r am Deviations

For purposes of this calculation the following assumptions were made: Gaseous

Nearest member of the public was W sector at 483 meters.

Actual 2017 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.

Fish , shellfish and shoreline pathways doses calculated. 40 CFR Part 190 Compl i ance

Dosimetry measurements (minus average of control stations) measured d ir ect radiation for the nearest member of the public. The nearest member of the public for direct rad i at i on is considered an individual that works in the wa r ehouse 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. A shielding factor of 7.00E-01 is applied for direct radiation.

Nearest res i dent was at SE sector at 937 meters.

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

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

The limits for Kr-85 , 1-1 29 , Pu-239 and othe r alpha-emitting transuranic rad i onucl i des with half-lives greater than one year were not exceeded. The ODCM does not require total body doses to the population and average doses to individuals in the population from gaseous effluents to a d i stance of 50 m i les from the s i te to be calc u lated. 36 Oyster Creek 2017 Annual Radioactive Effluent Release Report A summary of gaseous and liquid radiation doses to most likely exposed MEMBER OF THE PUBLIC was as follows: Location % of Applicable Estimated Age Distance Direction Applicable Effluent Organ Dose Group (meters) (toward) Limit Limit Unit Gamma-Noble Gas Air Dose 5.86E-04 All 500 ENE 5.86E-03 10 mrad Beta -Air Noble Gas Dose 2.15E-04 All 500 ENE 1.08E-03 20 mrad Total Body Noble Gas (Gamma) 2.61E-04 All 988 NNE 5.22E-03 5 mrem Noble Gas Skin (Beta) 3.66E-04 All 988 NNE 2.44E-03 15 mrem Iodine , Particulate , Bone 5.39E-01 Child 972 ESE 3.59E+OO 15 mrem Carbon-14

A Program Deviation was not reported as required in the 2016 Annual Radiological Effluent Release Report in Section J. Program Devia t ions. A turbine building (TB) effluent tritium sample was not collected for the first quarter of 2016 within the required time frame. 11 4 Oyster Creek 2017 Annual Radioactive Effluent Release Report ORIGINAL PAGE Oyster Creek 2016 Annual Radioactive Effluent Release Report a third party vendor increased the time to locate, order and receive the new output card which resulted in the monitoring system being inoperable for more than 30 days. 2. The Turbine Building Ventilation Monitor i ng System Effluent Flow Measuring Device was declared inoperable from February 10 , 2016 through May 17, 2016 (97 days). During the performance of the Turbine Building RAGEMS Sample and Effluent Flow -Functional Test surveillance , the alarm for loss of flow from the feed pump room was not received as required by the acceptance criteria of the surveillance. The issue was entered into our Corrective Action Program and the Effluent Flow Measuring Device was declared inoperable. Compensatory sampling was initiated per the ODCM. After review of the surveillance performance and plant response during the surveillance , it was determined that the flow indication did not reach the alarm set point due to static pressure on the high side of the delta pressure transmitter.

The surveillance was revised to address the static pressure issue and it was determined by the station to perform the surveillance at the next scheduled quarterly performance of the surveillance which resulted in the Effluent Flow Measuring Device being inoperable for more than 30 days. 3. The Reactor Building Service Water Radiation Monitor was declared inoperable from August 11 , 2016 through September 22 , 2016 (41 days). During the weekly performance of the source check of the Reactor Building Service Water Radiation Monitor , the LCD monitor for the monitor turned off and abnormal conditions were observed. The issue was entered into our Corrective Action Program and the Reactor Building Service Water Radiation Monitor was declared inoperable. Compensatory sampling was initiated per the ODCM. Troubleshooting identified that the DC power supply was degraded due to a failed beacon bulb. The components were not available on site and the components were ordered through the vendor. Due to the vendor having limited availability of the components , it took 31 days for the vendor to ship the components. The power supply and the beacon bulb were replaced as soon as they arrived. The time required for the components to arrive from the vendor resulted in the monitor being inoperable for more than 30 days. I. Releases from the Independent Spent Fuel Storage Facility:

The ISFSI is a closed system and the only exposure would be due to direct radiation. This includes iodines , particulates, and noble gases. Based on offsite TLD readings , dose due to direct radiation from the ISFSI was less than 1 mrem for 2016. Because it is a sealed unit , no radioactive material was released.

J. Program Deviations

1. There was one program deviation in 2016. A stack RAG EMS compensatory noble gas sample was not obtained within the ODCM required 8 hour9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months time frame. The stack RAGEMS low range monitor was declared inoperable at 12: 14 on October 17 , 2016 by Operations so the Instrument Maintenance Department could perform a calibration of the stack RAGEMS low range monitor. An activity on the work order for the calibration is for the Chemistry Department to line up flow to the by-pass sample line which stops flow from going through the low range monitor. 115 Oyster Creek 2017 Annual Radioactive Effluent Release Report ORIGINAL PAGE Oyster Creek 2016 Annual Radioactive Effluent Release Report Chemistry commenced the ODCM required compensatory sampling fo r the low range mon i tor being declared inoperable which is a noble gas sample every 8 hours9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months . The ca li b r ation was suspended d u e to a parts i ssue and the mon i tor was i nope r able longer t han is typical to perform a cal i bration. When the Instrument Maintenance Department completed the calibration they informed Operations that the calibration was completed satisfactorily.

The Operations crew that was on shift at the time the calibration was completed was a different crew than when the calibration began and did not realize that the monitor flow was in by-pass mode and declared the low range monitor operable at 16: 05 on October 27 , 2016. The Operations Department notified the on shift chemistry technician that they had declared the low range monitor operable. The on shift chemistry technician was not involved in lining the low range monitor to the by-pass mode and stopped performing the ODCM required compensatory sampling based on Operations declaring the monitor operable.

When Operations performed their daily source check early the next morning they noticed that the indication didn't change from when flow was supposed to be going th r ough the monitor and when they placed the monitor i n purge to perform the source check. Operations discovered that the flow was i n by-pass mode and requested Chemistry to perform the compensatory sampling. Chemistry immed i ately obtained a sample but i t was 9 hours1.041667e-4 days 0.0025 hours 1.488095e-5 weeks 3.4245e-6 months and 55 minutes from the previous sample so it did not meet t he ODCM requirement of performing a compensatory sample every 8 hours9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months . The low range mon i tor flow was returned to normal through the monitor and the low range monitor was returned to service. This event was entered into our Corrective Action Program and the cause was determined to be that the Operations Unit Supervisor failed to use procedure OP-AA-108-106 (Equipment Return to Serv i ce Checklist) due to the belief that the surveillance test returned the system to its norma l lineup and that no maintenance was performed during the surveillance test. The OP-AA-108-106 would have d i rected a work order search be performed wh i ch would have identified there were activities that still needed to be completed including returning flow to the monitor. A contr i buting cause of this event was that the surveillance procedure Stack RAGEMS Noble Gas Mon i tor Calibration (621.3.025) does not contain instructions as to the mode or condit i on in which the equ i pment is to be placed after completion of the maintenance activity or test. 116 Oyster Creek 2017 Annual Radioactive Effluent Release Report CORRECTED PAGE Oyster Creek 2016 Annual Radioactive Effluent Release Report a third party vendor increased the time to locate , order and receive the new output card which resulted in the monitoring system being inoperable for more than 30 days. 4. The Turbine Building Ventilation Monitoring System Effluent Flow Measuring Dev i ce was declared inoperable from February 10 , 2016 through May 17 , 2016 (97 days). During the performance of the Turbine Building RAG EMS Sample and Effluent Flow -Functional Test surveillance , the alarm for loss of flow from the feed pump room was not received as required by the acceptance criteria of the surveillance. The issue was entered into our Corrective Action Program and the Effluent Flow Measuring Device was declared inoperable. Compensatory sampling was initiated per the ODCM. After review of the surveillance performance and plant response during the surveillance , it was determined that the flow indication did not reach the alarm set point due to static pressure on the high side of the delta pressure transmitter.

The surveillance was revised to address the static pressure issue and it was determined by the station to perform the surveillance at the next scheduled quarterly performance of the surveillance which resulted in the Effluent Flow Measuring Device being inoperable for more than 30 days. 5. The Reactor Building Service Water Radiation Monitor was declared inoperable from August 11 , 2016 through September 22 , 2016 (41 days). During the weekly performance of the source check of the Reactor Building Service Water Radiation Monitor , the LCD monitor for the monitor turned off and abnormal conditions were observed. The issue was entered into our Corrective Action Program and the Reactor Building Service Water Radiation Monitor was declared inoperable. Compensatory sampling was initiated per the ODCM. Troubleshooting identified that the DC power supply was degraded due to a failed beacon bulb. The components were not available on site and the components were ordered through the vendor. Due to the vendor having limited availability of the components , it took 31 days for the vendor to ship the components. The power supply and the beacon bulb were replaced as soon as they arrived. The time required for the components to arrive from the vendor resulted in the monitor being inoperable for more than 30 days. K. Releases from the Independent Spent Fuel Storage Facility: The ISFSI is a closed system and the only exposure would be due to direct radiation. This includes iodines , particulates , and noble gases. Based on offsite TLD readings, dose due to direct radiation from the ISFSI was less than 1 mrem for 2016. Because it is a sealed unit , no radioactive material was released. L. Program Deviations

There were two program deviations in 2016. 1. A stack RAGEMS compensatory noble gas sample was not obtained within the ODCM required 8 hour9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months time frame. The stack RAGEMS low range monitor was declared inoperable at 12:14 on October 17 , 2016 by Operations so the Instrument Maintenance Department could perform a calibration of the stack RAGEMS low range monitor. An activity on the work order for the calibration is for the Chemistry Department to line up flow to the by-pass sample line which stops flow from going through the low range monitor. 117 Oyster Creek 2017 Annual Radioactive Effluent Release Report CORRECTED PAGE Oyster Creek 2016 Annual Radioactive Effluent Release Report Chemistry commenced the ODCM required compensatory sampling for the low range monitor being declared inoperable which is a noble gas sample every 8 hours9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months . The calibration was suspended due to a parts issue and the monitor was inoperable longer than is typical to perform a calibration. When the Instrument Maintenance Department completed the calibration they informed Operations that the calibration was completed satisfactorily.

The Operations crew that was on shift at the time the calibration was completed was a different crew than when the calibration began and did not realize that the monitor flow was in by-pass mode and declared the low range monitor operable at 16: 05 on October 27 , 2016. The Operations Department notified the on shift chemistry technician that they had declared the low range monitor operab l e. The on shift chemistry technician was not involved in lining the low range monitor to the by-pass mode and stopped performing the ODCM required compensatory sampling based on Operations declaring the monitor operable.

When Operations performed their daily source check early the next morning they noticed that the indication didn't change from when flow was supposed to be going through the monitor and when they placed the monitor in purge to perform the source check. Operations discovered that the flow was in by-pass mode and requested Chemistry to perform the compensatory sampling. Chemistry immediately obtained a sample but it was 9 hours1.041667e-4 days 0.0025 hours 1.488095e-5 weeks 3.4245e-6 months and 55 minutes from the previous sample so it did not meet the ODCM requirement of performing a compensatory sample every 8 hours9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months . The low range monitor flow was returned to normal through the monitor and the low range monitor was returned to service. This event was entered into our Corrective Action Program and the cause was determined to be that the Operations Unit Supervisor failed to use procedure OP-AA-108-106 (Equipment Return to Service Checklist) due to the belief that the surveillance test returned the system to its normal lineup and that no maintenance was performed during the surveillance test. The OP-AA-108-106 would have directed a work order search be performed which would have identified there were activities that still needed to be completed including returning flow to the monitor. A contributing cause of this event was that the surveillance procedure Stack RAGEMS Noble Gas Monitor Calib r ation (621.3.025) does not contain instructions as to the mode or condition in which the equipment is to be placed after completion of the ma i ntenance activity or test. 2. The first quarter Turbine Building (TB) effluent tritium sample was not obtained within the required time. This sample is required per Table 4.11.2.1.2-1 , Radioactive Gaseous Waste Sampling and Analysis Program , of the Oyster Creek ODCM OC-170-301) to be obtained once every 92 days with a 25% grace period. The previous sample was obtained on October 6 , 2015 a t 00: 15 am. Based on that sample time , the first quarter sample was required to be obtained no later than January 29, 2016 at 00: 16 am. The sample was completed February 18, 2016 at 09: 00 am. The cause for the delay in sampling was due to improper close out of the paperwork for the sample obtained October 6 , 2015. That paperwork was closed out several weeks after the actual sample date causing the next activity to be scheduled late. This issue was captured in our corrective action program and corrective actions taken to prevent recurrence. 118
