This document has been prepared in accordance with therequirements of PNPS Technical Specifications section 5.6.2.The REMP has been established to monitor the radiation and radioactivity released to theenvironment as a result of Pilgrim Station's operation. This program, initiated in August 1968,includes the collection, analysis, and evaluation of radiological data in order to assess the impact ofPilgrim Station on the environment and on the general public.SAMPLING AND ANALYSISThe environmental sampling media collected in the vicinity of PNPS and at distant locations includeair particulate filters, charcoal cartridges, animal forage, vegetation, cranberries, seawater, sediment,Irish moss, shellfish, American lobster, and fishes.During 2014, there were 1,240 samples collected from the atmospheric, aquatic, and terrestrialenvironments. In addition, 438 exposure measurements were obtained using environmentalthermoluminescent dosimeters (TLDs).A small number of inadvertent issues were encountered during 2014 in the collection ofenvironmental samples in accordance with the PNPS Offsite Dose Calculation Manual (ODCM).Two out of 440 TLDs were unaccounted for during the quarterly retrieval process. However, the 438TLDs that were collected provided the information necessary to assess ambient radiation levels inthe vicinity of Pilgrim Station. Equipment failures and power outages resulted in a small number ofinstances in which lower than normal volumes were collected at the airborne sampling stations. 571of 572 air particulate and charcoal cartridges were collected and analyzed as required. A fulldescription of any discrepancies encountered with the environmental monitoring program ispresented in Appendix D of this report.There were 1,296 analyses performed on the environmental media samples. Analyses wereperformed by the GEL Environmental Laboratory in Charleston, SC. Samples were analyzed asrequired by the PNPS ODCM.LAND USE CENSUSThe annual land use census in the vicinity of Pilgrim Station was conducted as required by thePNPS ODCM between September 09 and September 20, 2014. A total of 28 vegetable gardenshaving an area of more than 500 square feet were identified within five kilometers (three miles) ofPNPS. No new milk or meat animals were located during the census. Of the 28 garden locationsidentified, samples were collected at or near three of the gardens as part of the environmentalmonitoring program. Other samples of natural vegetation were also collected in predicted high-deposition areas.Page 6 RADIOLOGICAL IMPACT TO THE ENVIRONMENTDuring 2014, samples (except charcoal cartridges) collected as part of the REMP at Pilgrim Stationcontinued to contain detectable amounts of naturally-occurring and man-made radioactive materials.No samples indicated any detectable radioactivity attributable to Pilgrim Station operations. Offsiteambient radiation measurements using environmental TLDs beyond the site boundary rangedbetween 43 and 80 milliRoentgens per year. The range of ambient radiation levels observed withthe TLDs is consistent with natural background radiation levels for Massachusetts.RADIOLOGICAL IMPACT TO THE GENERAL PUBLICDuring 2014, radiation doses to the general public as a result of Pilgrim Station's operationcontinued to be well below the federal limits and much less than the collective dose due to othersources of man-made (e.g., X-rays, medical, fallout) and naturally-occurring (e.g., cosmic, radon)radiation.The calculated total body dose to the maximally exposed member of the general public fromradioactive effluents and ambient radiation resulting from PNPS operations for 2014 was about 0.6mrem for the year. This conservative estimate is well below the EPA's annual dose limit to anymember of the general public and is a fraction of a percent of the typical dose received from naturaland man-made radiation.CONCLUSIONSThe 2014 Radiological Environmental Monitoring Program for Pilgrim Station resulted in thecollection and analysis of hundreds of environmental samples and measurements. The dataobtained were used to determine the impact of Pilgrim Station's operation on the environment andon the general public.An evaluation of direct radiation measurements, environmental sample analyses, and dosecalculations showed that all applicable federal criteria were met. Furthermore, radiation levels andresulting doses were a small fraction of those that are normally present due to natural and man-made background radiation.Based on this information, there is no significant radiological impact on the environment or on thegeneral public due to Pilgrim Station's operation.Page 7

1.0 INTRODUCTION

The Radiological Environmental Monitoring Program for 2014 performed by Entergy NuclearCompany for Pilgrim Nuclear Power Station (PNPS) is discussed in this report. Since the operationof a nuclear power plant results in the release of small amounts of radioactivity and low levels ofradiation, the Nuclear Regulatory Commission (NRC) requires a program to be established tomonitor radiation and radioactivity in the environment (Reference 1). This report, which is required tobe published annually by Pilgrim Station's Technical Specifications section 5.6.2, summarizes theresults of measurements of radiation and radioactivity in the environment in the vicinity of the PilgrimStation and at distant locations during the period January 1 to December 31, 2014.The Radiological Environmental Monitoring Program consists of taking radiation measurements andcollecting samples from the environment, analyzing them for radioactivity content, and interpretingthe results. With emphasis on the critical radiation exposure pathways to humans, samples from theaquatic, atmospheric, and terrestrial environments are collected. These samples include, but are notlimited to: air, animal forage, vegetation, cranberries, seawater, sediment, Irish moss, shellfish,American lobster, and fish. Thermoluminescent dosimeters (TLDs) are placed in the environment tomeasure gamma radiation levels. The TLDs are processed and the environmental samples areanalyzed to measure the very low levels of radiation and radioactivity present in the environment asa result of PNPS operation and other natural and man-made sources. These results are reviewedby PNPS's Chemistry staff and have been reported semiannually or annually to the NuclearRegulatory Commission and others since 1972.In order to more fully understand how a nuclear power plant impacts humans and the environment,background information on radiation and radioactivity, natural and man-made sources of radiation,reactor operations, radioactive effluent controls, and radiological impact on humans is provided. It isbelieved that this information will assist the reader in understanding the radiological impact on theenvironment and humans from the operation of Pilgrim Station.1.1 Radiation and RadioactivityAll matter is made of atoms. An atom is the smallest part into which matter can be broken down andstill maintain all its chemical properties. Nuclear radiation is energy, in the form of waves or particlesthat is given off by unstable, radioactive atoms.Radioactive material exists naturally and has always been a part of our environment. The earth'scrust, for example, contains radioactive uranium, radium, thorium, and potassium. Someradioactivity is a result of nuclear weapons testing. Examples of radioactive fallout that is normallypresent in environmental samples are cesium-1 37 and strontium-90. Some examples of radioactivematerials released from a nuclear power plant are cesium-137, iodine-131, strontium-90, and cobalt-60.Radiation is measured in units of millirem, much like temperature is measured in degrees. A milliremis a measure of the biological effect of the energy deposited in tissue. The natural and man-maderadiation dose received in one year by the average American is about 620 mrem (References 2, 3,4).Radioactivity is measured in curies. A curie is that amount of radioactive material needed to produce37,000,000,000 nuclear disintegrations per second. This is an extremely large amount ofradioactivity in comparison to environmental radioactivity. That is why radioactivity in theenvironment is measured in picocuries. One picocurie is equal to one trillionth of a curie.Page 8 1.2 Sources of RadiationAs mentioned previously, naturally occurring radioactivity has always been a part of ourenvironment. Table 1.2-1 shows the sources and doses of radiation from natural and man-madesources.Table 1.2-1Radiation Sources and Corresponding Doses (1)NATURAL MAN-MADERadiation Dose Radiation DoseSource (millirem/year) Source (millirem/year)Internal, inhalation(2) 230 Medical'3) 300External, space 30 Consumer4) 12Internal, ingestion 30 Industrial(5) 0.6External, terrestrial 20 Occupational 0.6Weapons Fallout < 1Nuclear Power Plants < 1Approximate Total 310 Approximate Total 315Combined Annual Average Dose: Approximately 620 to 625 millirem/year(1) Information from NCRP Reports 160 and 94(2) Primarily from airborne radon and its radioactive progeny(3) Includes CT (150 millirem), nuclear medicine (74 mrem), interventional fluoroscopy (43 mrem) andconventional radiography and fluoroscopy (30 mrem)(4) Primarily from cigarette smoking (4.6 mrem), commercial air travel (3.4 mrem), building materials(3.5 mrem), and mining and agriculture (0.8 mrem)(5) Industrial, security, medical, educational, and researchCosmic radiation from the sun and outer space penetrates the earth's atmosphere and continuouslybombards us with rays and charged particles. Some of this cosmic radiation interacts with gasesand particles in the atmosphere, making them radioactive in turn. These radioactive byproducts fromcosmic ray bombardment are referred to as cosmogenic radionuclides. Isotopes such as beryllium-7and carbon-14 are formed in this way. Exposure to cosmic and cosmogenic sources of radioactivityresults in about 30 mrem of radiation dose per year.Additionally, natural radioactivity is in our body and in the food we eat (about 30 millirem/yr), theground we walk on (about 20 millirem/yr) and the air we breathe (about 230 millirem/yr). The majorityof a person's annual dose results from exposure to radon and thoron in the air we breathe. Thesegases and their radioactive decay products arise from the decay of naturally occurring uranium,thorium and radium in the soil and building products such as brick, stone, and concrete. Radon andthoron levels vary greatly with location, primarily due to changes in the concentration of uranium andthorium in the soil. Residents at some locations in Colorado, New York, Pennsylvania, and NewJersey have a higher annual dose as a result of higher levels of radon/thoron gases in these areas.Page 9 In total, these various sources of naturally-occurring radiation and radioactivity contribute to a totaldose of about 310 mrem per year.In addition to natural radiation, we are normally exposed to radiation from a number of man-madesources. The single largest doses from man-made sources result from therapeutic and diagnosticapplications of x-rays and radiopharmaceuticals. The annual dose to an individual in the U.S. frommedical and dental exposure is about 300 mrem. Consumer activities, such as smoking, commercialair travel, and building materials contribute about 13 mrem/yr. Much smaller doses result fromweapons fallout (less than 1 mrem/yr) and nuclear power plants. Typically, the average person inthe United States receives about 314 mrem per year from man-made sources. The collective dosefrom naturally-occurring and man-made sources results in a total dose of approximately 620 mrem/yrto the average American.1.3 Nuclear Reactor OperationsPilgrim Station generates about 700 megawatts of electricity at full power, which is enough electricityto supply the entire city of Boston, Massachusetts. Pilgrim Station is a boiling water reactor whosenuclear steam supply system was provided by General Electric Co. The nuclear station is located ona 1600-acre site about eight kilometers (five miles) east-southeast of the downtown area ofPlymouth, Massachusetts. Commercial operation began in December 1972.Pilgrim Station was operational during most of 2014, with the exception of a four day outage in mid-May to repair a feed pump seal, and a six day power reduction in mid-August to repair a feedwaterheater. The resulting monthly capacity factors are presented in Table 1.3-1.TABLE 1.3-1PNPS OPERATING CAPACITY FACTOR DURING 2014(Based on rated reactor thermal power of 2028 Megawatts-Thermal)Month Percent CapacityJanuary 99.9%February 99.9%March 98.8%April 99.8%May 82.0%June 99.1%July 99.9%August 85.8%September 99.9%October 99.0%November 99.8%December 98.4%Annual Average 96.8%Page 10 Nuclear-generated electricity is produced at Pilgrim Station by many of the same techniques used forconventional oil and coal-generated electricity. Both systems use heat to boil water to producesteam, The steam turns a turbine, which turns a generator, producing electricity. In both cases, thesteam passes through a condenser where it changes back into water and recirculates back throughthe system. The cooling water source for Pilgrim Station is the Cape Cod Bay.The key difference between Pilgrim's nuclear power and conventional power is the source of heatused to boil the water. Conventional plants bum fossil fuels in a boiler, while nuclear plants makeuse of uranium in a nuclear reactor.Inside the reactor, a nuclear reaction called fission takes place. Particles, called neutrons, strike thenucleus of a uranium-235 atom, causing it to split into fragments called radioactive fission products.The splitting of the atoms releases both heat and more neutrons. The newly-released neutrons thencollide with and split other uranium atoms, thus making more heat and releasing even moreneutrons, and on and on until the uranium fuel is depleted or spent. This process is called a chainreaction.The operation of a nuclear reactor results in the release of small amounts of radioactivity and lowlevels of radiation. The radioactivity originates from two major sources, radioactive fission productsand radioactive activation products.Radioactive fission products, as illustrated in Figure 1.3-1 (Reference 5), originate from the fissioningof the nuclear fuel. These fission products get into the reactor coolant from their release by minuteamounts of uranium on the outside surfaces of the fuel cladding, by diffusion through the fuel pelletsand cladding and, on occasion, through defects or failures in the fuel cladding. These fissionproducts circulate along with the reactor coolant water and will deposit on the internal surfaces ofpipes and equipment. The radioactive fission products on the pipes and equipment emit radiation.Examples of some fission products are krypton-85 (Kr-85), strontium-90 (Sr-90), iodine-131 (1-131),xenon-1 33 (Xe-1 33), and cesium-1 37 (Cs-1 37).Page II Nuclear FissionFission is the splitting of the uranium-235 atom by a neutron torelease heat and more neutrons, creating a chain reaction.Radiation and fission products are by-products of the process.Radiation-RaditionNeutronUraniumUraniumFission ProductsFigure 1.3-1Fission Product FormationRadioactivePage 12 Radioactive activation products (see Figure 1.3-2), on the other hand, originate from two sources.The first is by neutron bombardment of the hydrogen, oxygen and other gas (helium, argon,nitrogen) molecules in the reactor cooling water. The second is a result of the fact that the internalsof any piping system or component are subject to minute yet constant corrosion from the reactorcooling water. These minute metallic particles (for example: nickel, iron, cobalt, or magnesium) aretransported through the reactor core into the fuel region, where neutrons may react with the nuclei ofthese particles, producing radioactive products. So, activation products are nothing more thanordinary naturally-occurring atoms that are made unstable or radioactive by neutron bombardment.These activation products circulate along with the reactor coolant water and will deposit on theinternal surfaces of pipes and equipment. The radioactive activation products on the pipes andequipment emit radiation. Examples of some activation products are manganese-54 (Mn-54), iron-59 (Fe-59), cobalt-60 (Co-60), and zinc-65 (Zn-65).--0Co-60NeutronStableCobalt NucleusRadioactiveCobalt NucleusFigure 1.3-2Radioactive Activation Product FormationAt Pilgrim Nuclear Power Station there are five independent protective barriers that confine theseradioactive materials. These five barriers, which are shown in Figure 1.3-3 (Reference 5), are:* fuel pellets;* fuel cladding;* reactor vessel and piping;P primary containment (drywell and torus); and,* secondary containment (reactor building).Page 13 SIMPLIFIED DIAGRAM OF A BOILING WATER REACTOR4. PRIMARY CONTAINMENT1. FUEL PELLETS2./REACTORBUILDINGDRYWELLFigure 1.3-3Barriers To Confine Radioactive MaterialsPage 14 The ceramic uranium fuel pellets provide the first barrier. Most of the radioactive fission products areeither physically trapped or chemically bound between the uranium atoms, where they will remain.However, a few fission products that are volatile or gaseous may diffuse through the fuel pellets intosmall gaps between the pellets and the fuel cladding.The second barrier, the fuel cladding, consists of zirconium alloy tubes that confine the fuel pellets.The small gaps between the fuel and the cladding contain the noble gases and volatile iodines thatare types of radioactive fission products. This radioactivity can diffuse to a small extent through thefuel cladding into the reactor coolant water.The third barrier consists of the reactor pressure vessel, steel piping and equipment that confine thereactor cooling water. The reactor pressure vessel, which holds the reactor fuel, is a 65-foot high by19-foot diameter tank with steel walls about nine inches thick. This provides containment forradioactivity in the primary coolant and the reactor core. However, during the course of operationsand maintenance, small amounts of radioactive fission and activation products can escape throughvalve leaks or upon breaching of the primary coolant system for maintenance.The fourth barrier is the primary containment. This consists of the drywell and the torus. The drywellis a steel lined enclosure that is shaped like an inverted light bulb. An approximately five foot thickconcrete wall encloses the drywell's steel pressure vessel. The torus is a donut-shaped pressuresuppression chamber. The steel walls of the torus are nine feet in diameter with the donut itselfhaving an outside diameter of about 130 feet. Small amounts of radioactivity may be released fromprimary containment during maintenance.The fifth barrier is the secondary containment or reactor building. The reactor building is theconcrete building that surrounds the primary containment. This barrier is an additional safety featureto contain radioactivity that may escape from the primary containment. This reactor building isequipped with a filtered ventilation system that is used when needed to reduce the radioactivity thatescapes from the primary containment.The five barriers confine most of the radioactive fission and activation products. However, smallamounts of radioactivity do escape via mechanical failures and maintenance on valves, piping, andequipment associated with the reactor cooling water system. The small amounts of radioactiveliquids and gases that do escape the various containment systems are further controlled by the liquidpurification and ventilation filtration systems. Also, prior to a release to the environment, controlsystems exist to collect and purify the radioactive effluents in order to reduce releases to theenvironment to as low as is reasonably achievable. The control of radioactive effluents at PilgrimStation will be discussed in more detail in the next section.Page 15 1.4 Radioactive Effluent ControlThe small amounts of radioactive liquids and gases that might escape the five barriers are purified inthe liquid and gaseous waste treatment systems, then monitored for radioactivity, and released onlyif the radioactivity levels are below the federal release limits.Radioactivity released from the liquid effluent system to the environment is limited, controlled, andmonitored by a variety of systems and procedures which include:" reactor water cleanup system;" liquid radwaste treatment system;" sampling and analysis of the liquid radwaste tanks; and,* liquid waste effluent discharge header radioactivity monitor.The purpose of the reactor water cleanup system is to continuously purify the reactor cooling waterby removing radioactive atoms and non-radioactive impurities that may become activated by neutronbombardment. A portion of the reactor coolant water is diverted from the primary coolant systemand is directed through ion exchange resins where radioactive elements, dissolved and suspendedin the water, are removed through chemical processes. The net effect is a substantial reduction ofthe radioactive material that is present in the primary coolant water and consequently the amount ofradioactive material that might escape from the system.Reactor cooling water that might escape the primary cooling system and other radioactive watersources are collected in floor and equipment drains. These drains direct this radioactive liquid wasteto large holdup tanks. The liquid waste collected in the tanks is purified again using the liquidradwaste treatment system, which consists of a filter and ion exchange resins.Processing of liquid radioactive waste results in large reductions of radioactive liquids dischargedinto Cape Cod Bay. Of all wastes processed through liquid radwaste treatment, 90 to 95 percent ofall wastes are purified and the processed liquid is re-used in plant systems.Prior to release, the radioactivity in the liquid radwaste tank is sampled and analyzed to determine ifthe level of radioactivity is below the release limits and to quantify the total amount of radioactiveliquid effluent that would be released. If the levels are below the federal release limits, the tank isdrained to the liquid effluent discharge header.This liquid waste effluent discharge header is provided with a shielded radioactivity monitor. Thisdetector is connected to a radiation level meter and a strip chart recorder in the Control Room. Theradiation alarm is set so that the detector will alarm before radioactivity levels exceed the releaselimits. The liquid effluent discharge header has an isolation valve. If an alarm is received, the liquideffluent discharge valve will automatically close, thereby terminating the release to the Cape CodBay and preventing any liquid radioactivity from being released that may exceed the release limits.An audible alarm notifies the Control Room operator that this has occurred.Some liquid waste sources which have a low potential for containing radioactivity, and/or maycontain very low levels of contamination, may be discharged directly to the discharge canal withoutpassing through the liquid radwaste discharge header. One such source of liquids is the neutralizingsump. However, prior to discharging such liquid wastes, the tank is thoroughly mixed and arepresentative sample is collected for analysis of radioactivity content prior to being discharged.Page 16 Another means for adjusting liquid effluent concentrations to below federal limits is by mixing plantcooling water from the condenser with the liquid effluents in the discharge canal. This larger volumeof cooling water further dilutes the radioactivity levels far below the release limits.The preceding discussion illustrates that many controls exist to reduce the radioactive liquid effluentsreleased to the Cape Cod Bay to as far below the release limits as is reasonably achievable.Radioactive releases from the radioactive gaseous effluent system to the environment are limited,controlled, and monitored by a variety of systems and procedures which include:* reactor building ventilation system;" reactor building vent effluent radioactivity monitor;* sampling and analysis of reactor building vent effluents;* standby gas treatment system;* main stack effluent radioactivity monitor and sampling;* sampling and analysis of main stack effluents;* augmented off-gas system;* steam jet air ejector (SJAE) monitor; and,* off-gas radiation monitor.The purpose of the reactor building ventilation system is to collect and exhaust reactor building air.Air collected from contaminated areas is filtered prior to combining it with air collected from otherparts of the building. This combined airflow is then directed to the reactor building ventilation plenumthat is located on the side of the reactor building. This plenum, which vents to the atmosphere, isequipped with a radiation detector. The radiation level meter and strip chart recorder for the reactorbuilding vent effluent radioactivity monitor is located in the Control Room. To supplement theinformation continuously provided by the detector, air samples are taken periodically from the reactorbuilding vent and are analyzed to quantify the total amount of tritium and radioactive gaseous andparticulate effluents released.If air containing elevated amounts of noble gases is routed past the reactor building vent's effluentradioactivity monitor, an alarm will alert the Control Room operators that release limits are beingapproached. The Control Room operators, according to procedure, will isolate the reactor buildingventilation system and initiate the standby gas treatment system to remove airborne particulates andgaseous halogen radioactivity from the reactor building exhaust. This filtration assembly consists ofhigh-efficiency particulate air filters and charcoal adsorber beds. The purified air is then directed tothe main stack. The main stack has dilution flow that further reduces concentration levels ofgaseous releases to the environment to as far below the release limits as is reasonably achievable.The approximately 335 foot tall main stack has a special probe inside it that withdraws a portion ofthe air and passes it through a radioactivity monitoring system. This main stack effluent radioactivitymonitoring system continuously samples radioactive particulates, iodines, and noble gases. Grabsamples for a tritium analysis are also collected at this location. The system also containsradioactivity detectors that monitor the levels of radioactive noble gases in the stack flow and displaythe result on radiation level meters and strip chart recorders located in the Control Room. Tosupplement the information continuously provided by the detectors, the particulate, iodine, tritium,and gas samples are analyzed periodically to quantify the total amount of radioactive gaseouseffluent being released.The purpose of the augmented off-gas system is to reduce the radioactivity from the gases that areremoved from the condenser. This purification system consists of two 30-minute holdup lines toPage 17 reduce the radioactive gases with short half-lives, several charcoal adsorbers to remove radioactiveiodines and further retard the short half-life gases, and offgas filters to remove radioactiveparticulates. The recombiner collects free hydrogen and oxygen gas and recombines them intowater. This helps reduce the gaseous releases of short-lived isotopes of oxygen that have beenmade radioactive by neutron activation.The radioactive off-gas from the condenser is then directed into a ventilation pipe to which the off-gas radiation monitors are attached. The radiation level meters and strip chart recorders for thisdetector are also located in the Control Room. If a radiation alarm setpoint is exceeded, an audiblealarm will sound to alert the Control Room operators. In addition, the off-gas bypass and charcoaladsorber inlet valve will automatically re-direct the off-gas into the charcoal adsorbers if they aretemporarily being bypassed. If the radioactivity levels are not returned to below the alarm setpointwithin 13 minutes, the off-gas releases will be automatically isolated, thereby preventing anygaseous radioactivity from being released that may exceed the release limits.Therefore, for both liquid and gaseous releases, radioactive effluent control systems exist to collectand purify the radioactive effluents in order to reduce releases to the environment to as low as isreasonably achievable. The effluents are always monitored, sampled and analyzed prior to releaseto make sure that radioactivity levels are below the release limits. If the release limits are beingapproached, isolation valves in some of the waste effluent lines will automatically shut to stop therelease, or Control Room operators will implement procedures to ensure that federal regulatory limitsare always met.1.5 Radiological Impact on HumansThe final step in the effluent control process is the determination of the radiological dose impact tohumans and comparison with the federal dose limits to the public. As mentioned previously, thepurpose of continuous radiation monitoring and periodic sampling and analysis is to measure thequantities of radioactivity being released to determine compliance with the radioactivity release limits.This is the first stage for assessing releases to the environment.Next, calculations of the dose impact to the general public from Pilgrim Station's radioactive effluentsare performed. The purpose of these calculations is to periodically assess the doses to the generalpublic resulting from radioactive effluents to ensure that these doses are being maintained as farbelow the federal dose limits as is reasonably achievable. This is the second stage for assessingreleases to the environment.The types and quantities of radioactive liquid and gaseous effluents released from Pilgrim Stationduring each given year are reported to the Nuclear Regulatory Commission annually. The 2014Radioactive Effluents are provided in Appendix B and will be discussed in more detail in Section 3 ofthis report. These liquid and gaseous effluents were well below the federal release limits and were asmall percentage of the PNPS ODCM effluent control limits.These measurements of the physical and chemical nature of the effluents are used to determinehow the radionuclides will interact with the environment and how they can result in radiationexposure to humans. The environmental interaction mechanisms depend upon factors such as thehydrological (water) and meteorological (atmospheric) characteristics in the area. Information on thewater flow, wind speed, wind direction, and atmospheric mixing characteristics are used to estimatehow radioactivity will distribute and disperse in the ocean and the atmosphere.Page 18 The most important type of information that is used to evaluate the radiological impact on humans isdata on the use of the environment. Information on fish and shellfish consumption, boating usage,beach usage, locations of cows and goats, locations of residences, locations of gardens, drinkingwater supplies, and other usage information are utilized to estimate the amount of radiation andradioactivity received by the general public.The radiation exposure pathway to humans is the path radioactivity takes from its release point atPilgrim Station to its effect on man. The movement of radioactivity through the environment and itstransport to humans is portrayed in Figure 1.5-1.Page 19

Radioactive nitrogen-1 6 contained in thesteam flowing through the turbine accounts for the majority of this "sky shine" radiation exposureimmediately adjacent to the plant. Smaller amounts of ambient radiation result from low-levelradioactive waste stored at the site prior to shipping and disposal.To the extent possible, the radiological dose impact on humans is based on direct measurements ofradiation and radioactivity in the environment. When PNPS-related activity is detected in samplesthat represent a plausible exposure pathway, the resulting dose from such exposure is assessed(see Appendix A). However, the operation of Pilgrim Nuclear Power Station results in releases ofonly small amounts of radioactivity, and, as a result of dilution in the atmosphere and ocean, eventhe most sensitive radioactivity measurement and analysis techniques cannot usually detect thesetiny amounts of radioactivity above that which is naturally present in the environment. Therefore,radiation doses are calculated using radioactive effluent release data and computerized dosecalculations that are based on very conservative NRC-recommended models that tend to result inover-estimates of resulting dose. These computerized dose calculations are performed by or forEntergy Nuclear personnel. These computer codes use the guidelines and methodology set forth bythe NRC in Regulatory Guide 1.109 (Reference 6). The dose calculations are documented anddescribed in detail in the Pilgrim Nuclear Power Station's Offsite Dose Calculation Manual(Reference 7), which has been reviewed by the NRC.Monthly dose calculations are performed by PNPS personnel. It should be emphasized thatbecause of the very conservative assumptions made in the computer code calculations, themaximum hypothetical dose to an individual is considerably higher than the dose that would actuallybe received by a real individual.After dose calculations are performed, the results are compared to the federal dose limits for thepublic. The two federal agencies that are charged with the responsibility of protecting the publicfrom radiation and radioactivity are the Nuclear Regulatory Commission (NRC) and theEnvironmental Protection Agency (EPA).Page 21 The NRC, in 10CFR 20.1301 (Reference 8) limits the levels of radiation to unrestricted areasresulting from the possession or use of radioactive materials such that they limit any individual to adose of:* less than or equal to 100 mrem per year to the total body.In addition to this dose limit, the NRC has established design objectives for nuclear plant licensees.Conformance to these guidelines ensures that nuclear power reactor effluents are maintained as farbelow the legal limits as is reasonably achievable.The NRC, in 10CFR 50 Appendix I (Reference 9) establishes design objectives for the dose to amember of the general public from radioactive material in liquid effluents released to unrestrictedareas to be limited to:* less than or equal to 3 mrem per year to the total body; and,* less than or equal to 10 mrem per year to any organ.The air dose due to release of noble gases in gaseous effluents is restricted to:* less than or equal to 10 mrad per year for gamma radiation; and,* less than or equal to 20 mrad per year for beta radiation.The dose to a member of the general public from iodine-1 31, tritium, and all particulate radionuclideswith half-lives greater than 8 days in gaseous effluents is limited to:0 less than or equal to 15 mrem per year to any organ.The EPA, in 40CFR1 90.10 Subpart B (Reference 10), sets forth the environmental standards for theuranium fuel cycle. During normal operation, the annual dose to any member of the public from theentire uranium fuel cycle shall be limited to:* less than or equal to 25 mrem per year to the total body;* less than or equal to 75 mrem per year to the thyroid; and,* less than or equal to 25 mrem per year to any other organ.The summary of the 2014 radiological impact for Pilgrim Station and comparison with the EPA doselimits and guidelines, as well as a comparison with natural/man-made radiation levels, is presentedin Section 3 of this report.The third stage of assessing releases to the environment is the Radiological EnvironmentalMonitoring Program (REMP). The description and results of the REMP at Pilgrim Nuclear PowerStation during 2014 is discussed in Section 2 of this report.Page 22 2.0 RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM2.1 Pre-Operational Monitorinn ResultsThe Radiological Environmental Monitoring Program (REMP) at Pilgrim Nuclear Power Station wasfirst initiated in August 1968, in the form of a pre-operational monitoring program prior to bringing thestation on-line. The NRC's intent (Reference 11) with performing a pre-operational environmentalmonitoring program is to:* measure background levels and their variations in the environment in the area surroundingthe licensee's station; and," evaluate procedures, equipment, and techniques for monitoring radiation and radioactivity inthe environment.The pre-operational program (Reference 12) continued for approximately three and a half years,from August 1968 to June 1972. Examples of background radiation and radioactivity levelsmeasured during this time period are as follows:* Airborne Radioactivity Particulate Concentration (gross beta): 0.02 -1.11 pCi/m3;" Ambient Radiation (TLDs): 4.2 -22 micro-R/hr (37 -190 mR/yr);* Seawater Radioactivity Concentrations (gross beta): 12 -31 pCi/liter;* Fish Radioactivity Concentrations (gross beta): 2,200 -11,300 pCi/kg;* Milk Radioactive Cesium-1 37 Concentrations: 9.3 -32 pCi/liter;* Milk Radioactive Strontium-90 Concentrations: 4.7 -17.6 pCi/liter;" Cranberries Radioactive Cesium-1 37 Concentrations: 140 -450 pCi/kg;* Forage Radioactive Cesium-1 37 Concentrations: 150 -290 pCi/kg.This information from the pre-operational phase is used as a basis for evaluating changes inradiation and radioactivity levels in the vicinity of the plant following plant operation. In April 1972,just prior to initial reactor startup (June 12, 1972), Boston Edison Company implemented acomprehensive operational environmental monitoring program at Pilgrim Nuclear Power Station.This program (Reference 13) provides information on radioactivity and radiation levels in theenvironment for the purpose of:* demonstrating that doses to the general public and levels of radioactivity in the environmentare within established limits and legal requirements;* monitoring the transfer and long-term buildup of specific radionuclides in the environment torevise the monitoring program and environmental models in response to changing conditions;* checking the condition of the station's operation, the adequacy of operation in relation to theadequacy of containment, and the effectiveness of effluent treatment so as to provide amechanism of determining unusual or unforeseen conditions and, where appropriate, totrigger special environmental monitoring studies;* assessing the dose equivalent to the general public and the behavior of radioactivity releasedduring the unlikely event of an accidental release; and,Page 23

• determining whether or not the radiological impact on the environment and humans issignificant.The Nuclear Regulatory Commission requires that Pilgrim Station provide monitoring of the plantenvirons for radioactivity that will be released as a result of normal operations, including anticipatedoperational occurrences, and from postulated accidents. The NRC has established guidelines(Reference 14) that specify an acceptable monitoring program. The PNPS RadiologicalEnvironmental Monitoring Program was designed to meet and exceed these guidelines. Guidancecontained in the NRC's Radiological Assessment Branch Technical Position on EnvironmentalMonitoring (Reference 15) has been used to improve the program. In addition, the program hasincorporated the provisions of an agreement made with the Massachusetts Wildlife Federation(Reference 16). The program was supplemented by including improved analysis of shellfish andsediment at substantially higher sensitivity levels to verify the adequacy of effluent controls at PilgrimStation.2.2 Environmental Monitoring LocationsSampling locations have been established by considering meteorology, population distribution,hydrology, and land use characteristics of the Plymouth area. The sampling locations are dividedinto two classes, indicator and control. Indicator locations are those that are expected to showeffects from PNPS operations, if any exist. These locations were primarily selected on the basis ofwhere the highest predicted environmental concentrations would occur. While the indicator locationsare typically within a few kilometers of the plant, the control stations are generally located so as to beoutside the influence of Pilgrim Station. They provide a basis on which to evaluate fluctuations atindicator locations relative to natural background radiation and natural radioactivity and fallout fromprior nuclear weapons tests.The environmental sampling media collected in the vicinity of Pilgrim Station during 2014 included airparticulate filters, charcoal cartridges, animal forage, vegetation, cranberries, seawater, sediment,Irish moss, shellfish, American lobster, and fishes. The sampling medium, station description,station number, distance, and direction for indicator and control samples are listed in Table 2.2-1.These sampling locations are also displayed on the maps shown in Figures 2.2-1 through 2.2-6.The radiation monitoring locations for the environmental TLDs are shown in Figures 2.2-1 through2.2-4. The frequency of collection and types of radioactivity analysis are described in PilgrimStation's ODCM, Sections 3/4.5.The land-based (terrestrial) samples and monitoring devices are collected by Entergy personnel. Theaquatic samples are collected by Marine Research, Inc. The radioactivity analysis of samples andthe processing of the environmental TLDs are performed by the GEL Environmental Laboratory.The frequency, types, minimum number of samples, and maximum lower limits of detection (LLD) forthe analytical measurements, are specified in the PNPS ODCM. During 2003, a revision was madeto the PNPS ODCM to standardize it to the model program described in NUREG-1302 (Reference14) and the Branch Technical Position of 1979 (Reference 15). In accordance with thisstandardization, a number of changes occurred regarding the types and frequencies of samplecollections.In regard to terrestrial REMP sampling, routine collection and analysis of soil samples wasdiscontinued in lieu of the extensive network of environmental TLDs around PNPS, and the weeklycollection of air samples at 11 locations. Such TLD monitoring and air sampling would provide anearly indication of any potential deposition of radioactivity, and follow-up soil sampling could beperformed on an as-needed basis. Also, with the loss of the indicator milk sample at the PlymouthCounty Farm and the lack of a sufficient substitute location that could provide suitable volumes forPage 24 analysis, it was deemed unnecessary to continue to collect and analyze control samples of milk.Consequently, routine milk sampling was also dropped from the terrestrial sampling program. NRCguidance (Reference 14) contains provisions for collection of vegetation and forage samples in lieuof milk sampling. Such samples have historically been collected near Pilgrim Station as part of theroutine REMP program.In the area of marine sampling, a number of the specialized sampling and analysis requirementsimplemented as part of the Agreement with the Massachusetts Wildlife Federation (Reference 16)for licensing of a second reactor at PNPS were dropped. This agreement, made in 1977, waspredicated on the construction of a second nuclear unit, and was set to expire in 1987. However,since the specialized requirements were incorporated into the PNPS Technical Specifications at thetime, the requirements were continued. When the ODCM was revised in 1999 in accordance withNRC Generic Letter 89-01, the sampling program description was relocated to the ODCM. Whensteps were taken in 2003 to standardize the PNPS ODCM to the NUREG-1302 model, thespecialized marine sampling requirements were changed to those of the model program. Thesechanges include the following:* A sample of the surface layer of sediment is collected, as opposed to specialized depth-incremental sampling to 30 cm and subdividing cores into 2 cm increments.* Standard LLD levels of about 150 to 180 pCi/kg were established for sediment, as opposedto the specialized LLDs of 50 pCi/kg.* Specialized analysis of sediment for plutonium isotopes was removed.* Sampling of Irish moss, shellfish, and fish was rescheduled to a semiannual period, asopposed to a specialized quarterly sampling interval.* Analysis of only the edible portions of shellfish (mussels and clams), as opposed tospecialized additional analysis of the shell portions." Standard LLD levels of 130 to 260 pCi/kg were established for edible portions of shellfish, asopposed to specialized LLDs of 5 pCi/kg.The PNPS ODCM was revised in 2009. In conjunction with this revision, two changes were made tothe environmental sampling program. Due to damage from past storms to the rocky areas atManomet Point, there is no longer a harvestable population of blue mussels at this site. Severalattempts have been made over the past years to collect samples from this location, but all effortswere unsuccessful. Because of unavailability of mussels at this location as a viable humanfoodchain exposure pathway, this location was dropped from the sampling program. The otherchange involved the twice per year sampling of Group II fishes in the vicinity of the PNPS dischargeoutfall, represented by species such as cunner and tautog. Because these fish tend to move awayfrom the discharge jetty during colder months, they are not available for sampling at a six-monthsemi-annual sampling period. The sampling program was modified to reduce the sampling forGroup II fishes to once per year, when they are available during warmer summer months.Upon receipt of the analysis results from the analytical laboratories, the PNPS staff reviews theresults. If the radioactivity concentrations are above the reporting levels, the NRC must be notifiedwithin 30 days. For radioactivity that is detected that is attributable to Pilgrim Station's operation,calculations are performed to determine the cumulative dose contribution for the current year.Depending upon the circumstances, a special study may also be completed (see Appendix A for2014 special studies). Most importantly, if radioactivity levels in the environment become elevatedas a result of the station's operation, an investigation is performed and corrective actions arerecommended to reduce the amount of radioactivity to as far below the legal limits as is reasonablyachievable.The radiological environmental sampling locations are reviewed annually, and modified if necessary.A garden and milk animal census is performed every year to identify changes in the use of theenvironment in the vicinity of the station to permit modification of the monitoring and samplinglocations. The results of the 2014 Garden and Milk Animal Census are reported in Appendix C.Page 25 The accuracy of the data obtained through Pilgrim Station's Radiological Environmental MonitoringProgram is ensured through a comprehensive Quality Assurance (QA) programs. PNPS's QAprogram has been established to ensure confidence in the measurements and results of theradiological monitoring program through:" Regular surveillances of the sampling and monitoring program;" An annual audit of the analytical laboratory by the sponsor companies;* Participation in cross-check programs;* Use of blind duplicates for comparing separate analyses of the same sample; and," Spiked sample analyses by the analytical laboratory.QA audits and inspections of the Radiological Environmental Monitoring Program are performed bythe NRC, American Nuclear Insurers, and by the PNPS Quality Assurance Department.The GEL Environmental Laboratory conducts extensive quality assurance and quality controlprograms. The 2014 results of these programs are summarized in Appendix E. These resultsindicate that the analyses and measurements performed during 2014 exhibited acceptable precisionand accuracy.Page 26 2.3 Interpretation of Radioactivity Analyses ResultsThe following pages summarize the analytical results of the environmental samples collected during2014. Data for each environmental medium are included in a separate section. A table thatsummarizes the year's data for each type of medium follows a discussion of the sampling programand results. The unit of measurement for each medium is listed at the top of each table. The lefthand column contains the radionuclides being reported, total number of analyses of thatradionuclide, and the number of measurements that exceed ten times the yearly average for thecontrol station(s). The latter are classified as "non-routine" measurements. The next column liststhe Lower Limit of Detection (LLD) for those radionuclides that have detection capabilityrequirements specified in the PNPS ODCM.Those sampling stations within the range of influence of Pilgrim Station and which could conceivablybe affected by its operation are called "indicator" stations. Distant stations, which are beyond plantinfluence, are called "control" stations. Ambient radiation monitoring stations are broken down intofour separate zones to aid in data analysis.For each sampling medium, each radionuclide is presented with a set of statistical parameters. Thisset of statistical parameters includes separate analyses for (1) the indicator stations, (2) the stationhaving the highest annual mean concentration, and (3) the control stations. For each of these threegroups of data, the following values are calculated:* The mean value of detectable concentrations, including only those values above LLD;" The standard deviation of the detectable measurements;" The lowest and highest concentrations; and,* The number of positive measurements (activity which is three times greater than the standarddeviation), out of the total number of measurements.Each single radioactivity measurement datum is based on a single measurement and is reported asa concentration plus or minus one standard deviation. The quoted uncertainty represents only therandom uncertainty associated with the measurement of the radioactive decay process (countingstatistics), and not the propagation of all possible uncertainties in the sampling and analysis process.A sample or measurement is considered to contain detectable radioactivity if the measured value(e.g., concentration) exceeds three times its associated standard deviation. For example, avegetation sample with a cesium-137 concentration of 85 +/- 21 pCi/kilogram would be considered"positive" (detectable Cs-1 37), whereas another sample with a concentration of 60 +/- 32 pCi/kilogramwould be considered "negative", indicating no detectable cesium-137. The latter sample mayactually contain cesium-137, but the levels counted during its analysis were not significantly differentthan the background levels.The analytical laboratory that analyzes the various REMP samples employs a backgroundsubtraction correction for each analysis. A blank sample that is known not to contain any plant-related activity is analyzed for radioactivity, and the count rate for that analysis is used as thebackground correction. That background correction is then subtracted from the results for theanalyses in that given set of samples. For example, if the blank/background sample produces 50counts, and a given sample being analyzes produces 47 counts, then the net count for that sampleis reported as -3 counts. That negative value of -3 counts is used to calculate the concentration ofradioactivity for that particular analysis. Such a sample result is technically more valid than reportinga qualitative value such as "<LLD" (Lower limit of Detection) or "NDA" (No Detectable Activity".Page 27 As an example of how to interpret data presented in the results tables, refer to the first entry on thetable for air particulate filters (page 41). Gross beta (GR-B) analyses were performed on 571 routinesamples. None of the samples exceeded ten times the average concentration at the controllocation. The lower limit of detection (LLD) required by the ODCM is 0.01 pCi/m3.For samples collected from the ten indicator stations, 502 out of 519 samples indicated detectablegross beta activity at the three-sigma (standard deviation) level. The mean concentration of grossbeta activity in these 519 indicator station samples was 0.011 +/- 0.0058 (1.1E-2 +/- 5.8E-3) pCi/m3.Individual values ranged from -0.0055 to 0.034 (-5.5E-3 -3.4E-2) pCi/m3.The monitoring station which yielded the highest mean concentration was indicator location PC(Plymouth Center), which yielded a mean concentration of 0.013 +/- 0.0063 pCi/m3, based on 50detectable indications out of 52 samples observations. Individual values ranged from -0.00038 to0.032 pCi/m3.Fifty-two of the fifty-two samples showed detectable activity at the three-sigma level.At the control location, 51 out of 52 samples yielded detectable gross beta activity, for an averageconcentration of 0.012 +/- 0.0054 pCi/m3.Individual samples at the East Weymouth control locationranged from -0.0017 to 0.026 pCi/m3.Referring to the last entry row in the table, analyses for cesium-137 (Cs-137) were performed44times (quarterly composites for 11 stations

• 4 quarters). No samples exceeded ten times themean control station concentration. The required LLD value Cs-137 in the PNPS ODCM is 0.06pCi/m3.At the indicator stations, all 40 of the Cs-137 measurements were below the detection level. Thesame was true for the four measurements made on samples collected from the control location.2.4 Ambient Radiation MeasurementsThe primary technique for measuring ambient radiation exposure in the vicinity of Pilgrim Stationinvolves posting environmental thermoluminescent dosimeters (TLDs) at given monitoring locationsand retrieving the TLDs after a specified time period. The TLDs are then taken to a laboratory andprocessed to determine the total amount of radiation exposure received over the period. AlthoughTLDs can be used to monitor radiation exposure for short time periods, environmental TLDs aretypically posted for periods of one to three months. Such TLD monitoring yields average exposurerate measurements over a relatively long time period. The PNPS environmental TLD monitoringprogram is based on a quarterly (three month) posting period, and a total of 110 locations aremonitored using this technique. In addition, 27 of the 110 TLDs are located onsite, within the PNPSprotected/restricted area, where the general public does not have access.Out of the 440 TLDs (110 locations

• 4 quarters) posted during 2014, 438 were retrieved andprocessed. Those TLDs missing from their monitoring locations were lost to degradation of TLDholders. In addition, several TLDs that had been posted during the 4th Quarter of 2014 were left inthe field for an additional quarter due to limited access following January storms that interrupted theretrieval and exchange. When these TLDs were ultimately retrieved in Apr-2015, the exposureresults for the 6-month period monitored by the TLDs were reported for the 4th quarter 2014 period.These discrepancies are discussed in Appendix D. The results for environmental TLDs locatedoffsite, beyond the PNPS protected/restricted area fence, are presented in Table 2.4-1. Resultsfrom onsite TLDs posted within the restricted area are presented in Table 2.4-2. In addition to TLDresults for individual locations, results from offsite TLDs were grouped according to geographic zoneto determine average exposure rates as a function of distance. These results are summarized inTable 2.4-3. All of the listed exposure values represent continuous occupancy (2190 hr/qtr or 8760hr/yr).Page 28 Annual exposure rates measured at locations beyond the PNPS protected area boundary rangedfrom 43 to 173 mR/yr. The average exposure rate at control locations greater than 15 km fromPilgrim Station (i.e., Zone 4) was 60.0 +/- 7.7 mR/yr. When the 3-sigma confidence interval iscalculated based on these control measurements, 99% of all measurements of background ambientexposure would be expected to be between 37 and 83 mR/yr. The results for all TLDs within 15 km(excluding those Zone 1 TLDs posted within the site boundary) ranged from 47 to 82 mR/yr, whichcompares favorably with the preoperational results of 37 -190 mR/yr.Inspection of onsite TLD results listed in Table 2.4-2 indicates that all of those TLDs located withinthe PNPS protected/restricted area yield exposure measurements higher than the average naturalbackground. Such results are expected due to the close proximity of these locations to radiationsources onsite. The radionuclide nitrogen-16 (N-16) contained in steam flowing through the turbineaccounts for most of the exposure onsite. Although this radioactivity is contained within the turbineand is not released to the atmosphere, the "sky shine" which occurs from the turbine increases theambient radiation levels in areas near the turbine building.A small number of offsite TLD locations in close proximity to the protected/restricted area indicatedambient radiation exposure above expected background levels. All of these locations are on PilgrimStation controlled property, and experience exposure increases due to turbine sky shine (e.g.,locations OA, TC, PB, and P01) and/or transit and storage of radwaste onsite (e.g., locations BLEand BLW). Due to heightened security measures following September 11 2001, members for thegeneral public do not have access to such locations within the owner-controlled area.One TLD, located on the exterior wall of the Plymouth Memorial Hall, indicated an annual exposureof 80 mR in 2014. The higher exposure within the building at this location is due to the closeproximity of stone (granite) building material, which contains higher levels of naturally-occurringradioactivity.It should be noted that several of the TLDs used to calculate the Zone 1 averages presented inTable 2.4-3 are located on Pilgrim Station property. If the Zone 1 value is corrected for the near-siteTLDs (those less than 0.6 km from the Reactor Building), the Zone 1 mean falls from a value of 72.6+/- 23.1 mR/yr to 62.2 +/- 8.1 mR/yr. Additionally, exposure rates measured at areas beyond Entergy'scontrol did not indicate any increase in ambient exposure from Pilgrim Station operation. Forexample, the annual exposure rate calculated from the two TLDs adjacent to the nearest offsiteresidence 0.80 kilometers (0.5 miles) southeast of the PNPS Reactor Building was 64.9 +/- 7.5 mR/yr,which compares quite well with the average control location exposure of 62.2 +/- 8.1 mR/yr.In conclusion, measurements of ambient radiation exposure around Pilgrim Station do not indicateany significant increase in exposure levels. Although some increases in ambient radiation exposurelevel were apparent on Entergy property very close to Pilgrim Station, there were no measurableincreases at areas beyond Entergy's control.2.5 Air Particulate Filter Radioactivity AnalysesAirborne particulate radioactivity is sampled by drawing a stream of air through a glass fiber filter thathas a very high efficiency for collecting airborne particulates. These samplers are operatedcontinuously, and the resulting filters are collected weekly for analysis. Weekly filter samples areanalyzed for gross beta radioactivity, and the filters are then composited on a quarterly basis foreach location for gamma spectroscopy analysis. PNPS uses this technique to monitor 10 locationsin the Plymouth area, along with the control location in East Weymouth.Page 29 Out of 572 filters (11 locations

• 52 weeks), 571 samples were collected and analyzed during 2014.One set of filters was left on during a two-week period in Feb-2014 when the sampler at ManometSubstation was inaccessible due to ice buildup. Although the sampler was inaccessible, there wasno loss of sampling during the period. There were also a few instances where power was lost orpumps failed during the course of the sampling period at some of the air sampling stations, resultingin lower than normal sample volumes. All of these discrepancies are noted in Appendix D.The results of the analyses performed on these 571 filter samples are summarized in Table 2.5-1.Trend plots for the gross beta radioactivity levels at the near station, property line, and offsiteairborne monitoring locations are shown in Figures 2.5-1, 2.5-2 and 2.5-3, respectively. Gross betaradioactivity was detected in 553 of the filter samples collected, including 51 of the 52 controllocation samples. This gross beta activity arises from naturally-occurring radionuclides such asradon decay daughter products. Naturally-occurring beryllium-7 was detected in 44 out of 44 of thequarterly composites analyzed with gamma spectroscopy. No airborne radioactivity attributable toPilgrim Station was detected in any of the samples collected during 2014, and results of anydetectable naturally-occurring radioactivity were similar to those observed in the preoperationalmonitoring program.2.6 Charcoal Cartridge Radioactivity AnalysesAirborne radioactive iodine is sampled by drawing a stream of air through a charcoal cartridge after ithas passed through the high efficiency glass fiber filter. As is the case with the air particulate filters,these samplers are operated continuously, and the resulting cartridges are collected weekly foranalysis. Weekly cartridge samples are analyzed for radioactive iodine. The same eleven locationsmonitored for airborne particulate radioactivity are also sampled for airborne radioiodine.Out of 572 cartridges (11 locations

• 52 weeks), 571 samples were collected and analyzed during2014. One set of filters was left on during a two-week period in Feb-2014 when the sampler atManomet Substation was inaccessible due to ice buildup. Although the sampler was inaccessible,there was no loss of sampling during the period. There were also a few instances where power waslost or pumps failed during the course of the sampling period at some of the air sampling stations,resulting in lower than normal sample volumes. All of these discrepancies are noted in Appendix D.Despite such events during 2014, required LLDs were met on 571 of the 571 cartridges collectedduring 2014.The results of the analyses performed on these charcoal cartridges are summarized in Table 2.6-1.No airborne radioactive iodine attributable to Pilgrim Station was detected in any of the charcoalcartridges collected.2.7 Milk Radioactivity AnalysesIn July 2002, the Plymouth County Farm ceased operation of its dairy facility. This was historicallythe only dairy facility near Pilgrim Station, and had been sampled continuously since Pilgrim Stationbegan operation in 1972. Although attempts were made to obtain samples from an alternateindicator location within 5 miles as specified in NRC guidance (Reference 14), a suitable substitutelocation could not be found. Thus, milk collection at an indicator location was discontinued in July2002, but control samples of milk continued to be collected and analyzed in the event an indicatorlocation could be secured. In conjunction with the standardization of the ODCM during 2003, thedecision was made to remove milk sampling from the PNPS Radiological Environmental MonitoringProgram since no suitable milk sampling location existed in the vicinity of Pilgrim Station.The nearest milk animals to Pilgrim Station are located at the Plimoth Plantation, approximately 2.5miles west of PNPS, in a relatively upwind direction. Due to the limited number of milk animalsavailable, this location is not able to provide the necessary volume of 4 gallons of milk every twoPage 30 weeks to facilitate the milk sampling program and meet the required detection sensitivities. Althoughmilk sampling is not performed at Plimoth Plantation, effluent dose calculations are performed forthis location assuming the presence of a milk ingestion pathway, as part of the annual Effluent andWaste Disposal Report (Reference 17).As included in a provision in standard ODCM guidance in NUREG-1302 (Reference 13), samplingand analysis of vegetation from the offsite locations calculated to have the highest D/Q depositionfactor can be performed in lieu of milk sampling. Such vegetation sampling has been routinelyperformed at Pilgrim Station as part of the radiological environmental monitoring program, and theresults of this sampling are presented in Section 2.9.2.8 Foraae Radioactivity AnalysesSamples of animal forage (hay) had been collected in the past from the Plymouth County Farm, andfrom control locations in Bridgewater. However, due to the absence of any grazing animals within afive-mile radius of Pilgrim Station that are used for generation of food products (milk or meat), nosamples of forage were collected during 2014. A number of wild vegetation samples were collectedwithin a five mile radius of Pilgrim Station as part of the vegetable/vegetation sampling effort, andthe results of this sampling would provide an indication of any radioactivity potentially entering theforage-milk or forage-meat pathways. Results of the vegetable/vegetation sampling effort arediscussed in the following section.2.9 VegetableNecietation Radioactivity AnalysesSamples of vegetables and naturally-growing vegetation have historically been collected from thePlymouth County Farm and from the control locations in Bridgewater, Sandwich, and Norton.Results of the land-use census census are discussed in Appendix C. In addition to these gardensamples, naturally-growing vegetation is collected from locations yielding the highest D/Q depositionfactors. All of the various samples of vegetables/vegetation are collected annually and analyzed bygamma spectroscopy.Seventeen samples of vegetables/vegetation were collected and analyzed as required during 2014.Results of the gamma analyses of these samples are summarized in Table 2.9-1. Naturally-occurring beryllium-7, potassium-40, and actinium/thorium-228 were identified in several of thesamples collected. Cesium-137 was also detected in four out of 10 samples of vegetation collectedfrom indicator locations, and one of seven control samples collected, with concentrations rangingfrom non-detectable (<12 pCi/kg) up to 133 pCi/kg. The highest concentration of 133 pCi/kg wasdetected in a sample of natural vegetation collected from the Pine Hills area of the Pine Hills southof PNPS. This Cs-1 37 result is within of the normal range of average values expected for weapons-testing fallout (75 to 145 pCi/kg as projected from the pre-operational sampling program). It shouldbe noted that natural vegetation samples collected in the 1990s often showed detectable Cs-137from nuclear weapons tests up into the range of 300 to 400 pCi/kg, whereas soil samples oftenindicated concentrations in excess of 2000 pCi/kg. Cs-137 has a 30-year half-life, and measureableconcentrations still remain in soil and vegetation as a result of atmospheric nuclear weapons testingperformed during the 1950s through 1970s. Weekly particulate air filters collected from the CleftRock sampling station within 400 meters of where the vegetation was sampled indicated nodetectable Cs-1 37. A review of effluent data presented in Appendix B indicates that there were nomeasurable airborne releases of Cs-1 37 from Pilgrim Station during 2014 that could have attributedto this level. The sample with the highest level of Cs-137 also contained high levels of AcTh-228,indicating appreciable soil content on the vegetation. This sample of natural vegetation wasanalyzed "as is" without any measure to clean the samples as normally would be performed prior toconsuming vegetables, and would have detected any Cs-137 in soil adhering to those leavescollected. Certain species of plants such as sassafras are also known to concentrate chemicalPage 31 elements like cesium, and this higher-than-expected level is likely due to a combination of externalsoil contamination and bioconcentration in the leaves of the plants sampled. These levels are notbelieved to be indicative of any releases associated with Pilgrm Station. No radioactivity attributableto Pilgrim Station was detected in any of the vegetable/vegetation samples collected during 2014,and results of any detectable naturally-occurring radioactivity were similar to those observed in thepreoperational monitoring program.2.10 Cranberry Radioactivity AnalysesSamples of cranberries are normally collected from two bogs in the Plymouth area and from thecontrol location in Kingston. Samples of cranberries are collected annually and analyzed by gammaspectroscopy. In 2012, the bog on Bartlett Road ceased harvesting operations, and a sample wascollected from an alternate location along Beaver Dam Road. Samples were also not available fromthe historical control location in Halifax, and a substitute control sample was collected from a bog inKingston. These discrepancies are noted in Appendix D.Two samples of cranberries were collected and analyzed during 2014. One of the bogs normallysampled along Bartlett Road is no longer in production. Results of the gamma analyses of cranberrysamples are summarized in Table 2.10-1. Cranberry samples collected during 2014 yieldeddetectable levels of naturally-occurring beryllium-7, potassium-40, and actinium/thorium-228. Noradioactivity attributable to Pilgrim Station was detected in any of the samples collected during 2014,and results of any detectable naturally-occurring radioactivity were similar to those observed in thepreoperational monitoring program.2.11 Soil Radioactivity AnalysesIn the past, a survey of radioactivity in soil had been conducted once every three years at the 10 airsampling stations in the Plymouth area and the control location in East Weymouth. However, inconjunction with standardization of the ODCM during 2003, the soil survey effort was abandoned infavor of the extensive TLD monitoring effort at Pilgrim Station. Prior to ending the soil survey effort,there had been no apparent trends in radioactivity measurements at these locations.2.12 Surface Water Radioactivity AnalysesSamples of surface water are routinely collected from the discharge canal, Bartlett Pond in Manometand from the control location at Powder Point Bridge in Duxbury. Grab samples are collected weeklyfrom the Bartlett Pond and Powder Point Bridge locations. Samples of surface water are compositedevery four weeks and analyzed by gamma spectroscopy and low-level iodine analysis. Thesemonthly composites are further composited on a quarterly basis and tritium analysis is performed onthese quarterly samples.A total of 36 samples (3 locations

• 12 sampling periods) of surface water were collected andanalyzed as required during 2014. Results of the analyses of water samples are summarized inTable 2.12-1. Naturally-occurring potassium-40 was detected in several of the samples, especiallythose composed primarily of seawater. No radioactivity attributable to Pilgrim Station was detectedin any of the surface water samples collected during 2014.In response to the Nuclear Energy Institute Groundwater Protection Initiative, Pilgrim Stationinstalled a number of groundwater monitoring wells within the protected area in late 2007. Becauseall of these wells are onsite, they are not included in the offsite radiological monitoring program, andare not presented in this report. Details regarding Pilgrim Station's groundwater monitoring effortcan be found in the Annual Radioactive Effluent Release Report.Page 32 2.13 Sediment Radioactivity AnalysesSamples of sediment are routinely collected from the outfall area of the discharge canal and fromthree other locations in the Plymouth area (Manomet Point, Plymouth Harbor and Plymouth Beach),and from control locations in Duxbury and Marshfield. Samples are collected twice per year and areanalyzed by gamma spectroscopy.Twelve of twelve required samples of sediment were collected during 2014. Gamma analyses wereperformed on these samples. Results of the gamma analyses of sediment samples are summarizedin Table 2.13-1. Naturally-occurring beryllium-7, potassium-40, thallium-208, lead-12, lead-214,radium-226, and actinium/thorium-228 were detected in a number of the samples. No radioactivityattributable to Pilgrim Station was detected in any of the samples collected during 2014, and resultsof any detectable naturally-occurring radioactivity were similar to those observed in thepreoperational monitoring program.2.14 Irish Moss Radioactivity AnalysesSamples of Irish moss are collected from the discharge canal outfall and two other locations in thePlymouth area (Manomet Point, Ellisville), and from a control location in Marshfield (Brant Rock). Allsamples are collected on a semiannual basis, and processed in the laboratory for gammaspectroscopy analysis.Eight samples of Irish moss scheduled for collection during 2014 were obtained and analyzed.Results of the gamma analyses of these samples are summarized in Table 2.14-1. Naturally-occurring potassium-40 was detected in a number of the samples. No radioactivity attributable toPilgrim Station was detected in any of the samples collected during 2014, and results of anydetectable naturally-occurring radioactivity were similar to those observed in the preoperationalmonitoring program.2.15 Shellfish Radioactivity AnalysesSamples of blue mussels, soft-shell clams and quahogs are collected from the discharge canaloutfall and one other location in the Plymouth area (Plymouth Harbor), and from control locations inDuxbury and Marshfield. All samples are collected on a semiannual basis, and edible portionsprocessed in the laboratory for gamma spectroscopy analysis.Nine of the 10 required samples of shellfish meat scheduled for collection during 2014 wereobtained and analyzed. Samples were unavailable during the spring collection season due toscouring action from winter storms. This discrepancy is discussed in Appendix D. Results of thegamma analyses of these samples are summarized in Table 2.15-1. Naturally-occurring potassium-40 was detected in a number of the samples. No radioactivity attributable to Pilgrim Station wasdetected in any of the samples collected during 2014, and results of any detectable naturally-occurring radioactivity were similar to those observed in the preoperational monitoring program.Page 33 2.16 Lobster Radioactivity AnalysesSamples of lobsters are routinely collected from the outfall area of the discharge canal and fromcontrol locations in Cape Cod Bay and Vineyard Sound. Samples are collected monthly from thedischarge canal outfall from June through September and once annually from the control locations.All lobster samples are normally analyzed by gamma spectroscopy.Nine samples of lobsters were collected as required during 2014. Results of the gamma analyses ofthese samples are summarized in Table 2.16-1. Naturally-occurring potassium-40 was detected in anumber of the samples. No radioactivity attributable to Pilgrim Station was detected in any of thesamples collected during 2014, and results of any detectable naturally-occurring radioactivity weresimilar to those observed in the preoperational monitoring program.2.17 Fish Radioactivity AnalysesSamples of fish are routinely collected from the area at the outfall of the discharge canal and fromthe control locations in Cape Cod Bay and Buzzard's Bay. Fish species are grouped into four majorcategories according to their biological requirements and mode of life. These major categories andthe representative species are as follows:* Group I -Bottom-Oriented: Winter Flounder, Yellowtail Flounder" Group II -Near-Bottom Distribution: Tautog, Cunner, Pollock, Atlantic Cod, Hake" Group III -Anadromous: Alewife, Smelt, Striped Bass* Group IV -Coastal Migratory: Bluefish, Herring, Menhaden, MackerelGroup I fishes are sampled on a semiannual basis from the outfall area of the discharge canal, andon an annual basis from a control location. Group II, Ill, and IV fishes are sampled annually from thedischarge canal outfall and control location. All samples of fish are analyzed by gammaspectroscopy.Six samples of fish were collected during 2014. The autumn sample of Group I Fish (flounder) wasnot available from the Discharge Canal Outfall during the October sampling period due to seasonalunavailability as the fish moved away from the Discharge Outfall to deeper water. The seasonalsample of Group II fish (tautog; cunner) was not available from the Discharge Outfall due topopulation declines in the species along the outer breakwater. The sample of Group III fish (alewife,smelt, striped bass) from the control location was missed due to seasonal unavailability, fishingrestrictions, and low fish numbers during the latter half of the year. These discrepancies arediscussed in Appendix D. Results of the gamma analyses of fish samples collected are summarizedin Table 2.17-1. The only radionuclide detected in any of the fish samples was naturally-occurringpotassium-40. No radioactivity attributable to Pilgrim Station was detected in any of the fish samplescollected during 2014, and results of any detectable naturally-occurring radioactivity were similar tothose observed in the preoperational monitoring program.Page 34 Table 2.2-1Routine Radiological Environmental Sampling LocationsPilgrim Nuclear Power Station, Plymouth, MADescription Code Distance

The second method is based on actual measurements ofradioactivity in the environmental samples and on dose conversion factors recommended by theNuclear Regulatory Commission. The measured types and quantities of radioactive liquid andgaseous effluents released from Pilgrim Station during 2014 were reported to the NuclearRegulatory Commission, copies of which are provided in Appendix B. The measured levels ofradioactivity in the environmental samples that required dose calculations are listed in Appendix A.The maximum individual dose from liquid effluents was calculated using the following radiationexposure pathways:* shoreline external radiation during fishing and recreation at the Pilgrim Station Shorefront;* external radiation from the ocean during boating and swimming; and* ingestion of fish and shellfish.For gaseous effluents, the maximum individual dose was calculated using the following radiationexposure pathways:" external radiation from cloud shine and submersion in gaseous effluents;* inhalation of airborne radioactivity;" external radiation from soil deposition;* consumption of vegetables; and* consumption of milk and meat.The results from the dose calculations based on PNPS operations are presented in Table 3.0-1.The dose assessment data presented were taken from the "Radioactive Effluent Release Report" forthe period of January 1 through December 31, 2014 (Reference 17).Page 68 Table 3.0-1Radiation Doses from 2014 Pilgrim Station OperationsMaximum Individual Dose From Exposure Pathway -mrem/yrGaseous Liquid AmbientReceptor Effluents* Effluents Radiation** TotalTotal Body 0.045 0.00000029 0.52 0.57Thyroid 0.047 0.00000020 0.52 0.57Max. Organ 0.088 0.00000087 0.52 0.61* Gaseous effluent exposure pathway includes combined dose from particulates, iodines and tritiumin addition to noble gases, calculated at the nearest residence.** Ambient radiation dose for the hypothetical maximum-exposed individual at a location on PNPSproperty yielding highest ambient radiation exposure value as measured with TLDs.Two federal agencies establish dose limits to protect the public from radiation and radioactivity. TheNuclear Regulatory Commission (NRC) specifies a whole body dose limit of 100 mrem/yr to bereceived by the maximum exposed member of the general public. This limit is set forth in Section1301, Part 20, Title 10, of the U.S. Code of Federal Regulations (10CFR20). By comparison, theEnvironmental Protection Agency (EPA) limits the annual whole body dose to 25 mrem/yr, which isspecified in Section 10, Part 190, Title 40, of the Code of Federal Regulations (40CFR1 90).Another useful "gauge" of radiation exposure is provided by the amount of dose a typical individualreceives each year from natural and man-made sources of radiation. Such radiation doses aresummarized in Table 1.2-1. The typical American receives about 620 mrem/yr from such sources.As can be seen from the doses resulting from Pilgrim Station Operations during 2014, all values arewell within the federal limits specified by the NRC and EPA. In addition, the calculated doses fromPNPS operation represent only a fraction of a percent of doses from natural and man-maderadiation.In conclusion, the radiological impact of Pilgrim Station operations, whether based on actualenvironmental measurements or calculations made from effluent releases, would yield doses wellwithin any federal dose limits set by the NRC or EPA. Such doses represent only a smallpercentage of the typical annual dose received from natural and man-made sources of radiation.Page 69

The census was conducted bydriving along each improved road/street in the Plymouth area within 5 kilometers (3 miles) of PilgrimStation to survey for visible gardens with an area of greater than 500 square feet. In compasssectors where no gardens were identified within 5 km (SSW, WNW, NW, and NNW sectors), thesurvey was extended to 8 km (5 mi). A total of 28 gardens were identified in the vicinity of PilgrimStation. In addition, the Town of Plymouth Animal Inspector was contacted for information regardingmilk and meat animals.Atmospheric deposition (D/Q) values at the locations of the identified gardens were compared tothose for the existing sampling program locations. These comparisons enabled PNPS personnel toascertain the best locations for monitoring for releases of airborne radionuclides. Samples ofnaturally-growing vegetation were collected at the site boundary in the ESE and SE sectors tomonitor for atmospheric deposition in the vicinity of the nearest resident in the SE sector.In addition to these special sampling locations identified and sampled in conjunction with the 2014land use census, samples were also collected at or near the Plymouth County Farm (5.6 km W), andfrom control locations in Bridgewater (31 km W), Sandwich (21 km SSE), and Norton (49 km W).Samples of naturally-growing vegetation were also collected in the vicinity of the site boundarylocations yielding the highest deposition (D/Q) factors for each of the two release points. Theselocations, and their distance and direction relative to the PNPS Reactor Building, are as follows:Highest Main Stack D/Q: 1.2 km SSWHighest Reactor Building Vent D/Q: 0.6 km SE2 nhighest D/Q, both release points: 1.1 km SNo new milk or meat animals were identified during the land use census. In addition, the Town ofPlymouth Animal Inspector stated that their office is not aware of any animals at locations other thanthe Plimoth Plantation. Although milk sampling is not performed at Plimoth Plantation, effluent dosecalculations are performed for this location assuming the presence of a milk ingestion pathway, aspart of the Annual Radioactive Effluent Release Report (Reference 17).Page 82 APPENDIX DENVIRONMENTAL MONITORING PROGRAM DISCREPANCIESThere were a number of instances during 2014 in which inadvertent issues were encountered in thecollection of environmental samples. All of these issues were minor in nature and did not have anadverse effect on the results or integrity of the monitoring program. Details of these variousproblems are given below.During 2014, two offsite thermoluminescent dosimeters (TLD) were not recovered from theirassigned locations during the quarterly retrieval process. Degradation of the plastic cages housingthe TLDs resulted in the loss of the following TLDs: Valley Road -VR (Qtr 2); and Long Pond &Drew Road -LD (Qtr 3). In each of these cases, the plastic cage holding the TLD were replacedand a new TLD posted. Despite these losses, the 438 TLDs that were collected (99.5%) allowed foradequate assessment of the ambient radiation levels in the vicinity of Pilgrim Station.Of the 110 TLDs that had been posted during the 4th Quarter of 2014, 51 were left in the field for anadditional quarter due to limited access following January storms that interrupted the retrieval andexchange process. When these TLDs were ultimately retrieved in Apr-2015, the exposure results forthe 6-month period monitored by the TLDs were reported for both the 4th quarter 2014 and 1stquarter 2015 periods. Although all of the TLDs were retrieved and none were missing, this isreported as a discrepancy due to the departure from the normal quarterly posting period.Within the air sampling program, there were a few instances in which continuous sampling wasinterrupted at the eleven airborne sampling locations during 2014. Most of these interruptions weredue to short-term power losses and were sporadic and of limited duration (less than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> out ofthe weekly sampling period). Such events did not have any significant impact on the scope andpurpose of the sampling program, and lower limits of detection (LLDs) were met for both airborneparticulates and iodine-131 on 571 of the 571 filters/cartridges collected.Out of 572 filters (11 locations

• 52 weeks), 571 samples were collected and analyzed during 2014.During the week between 03-Feb-2014 and 11-Feb-2014, frozen snow and ice prevented access tothe sampling station at Manomet Substation (MS). The area did not become accessible until 21-Feb-2014. Although the station was inaccessible, the sampler never lost power and continued to runduring the 428-hour period since the previous collection. Instead of collecting two filters during theperiod, one filter was in-service during the entire period, which reduced the total complement offilters collected from this location from the normal number of 52 down to 51. Again, it must beemphasized that the station continued to sample during the duration and no monitoring time waslost.The configuration of air samplers that had been in use at Pilgrim Station since the early 1980s, wasreplaced between June and August of 2012. Both the pumps and dry gas meters were replaced,and operating experience since changing over to the new configuration has been favorable.Although the occurrence of pump failures and gas meter problems have been largely eliminated, thenew configuration is still subject to trips of the ground fault interrupt circuit (GFCI). Such problemscan be encountered at air samplers located at the East Breakwater and Pedestrian Bridge. Both ofthese locations are immediately adjacent to the shoreline and are subject to significant wind-blownsalt water, and are prone to tripping of the GFCI. The following table contains a listing of largerproblems encountered with air sampling stations during 2014, many of which resulted in loss of morethan 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> during the sampling period.Page 83 Location Sampling Period Sampling Problem Description/ResolutionHours LostMS 02/03 to 02/21 None Filter left on for 2-week period due to inaccessibility at0.0 of 428.0 location of sampler; filters collected once accessiblePB 02/11 to 02/20 40.4 of 216.1 Trip of GFCl outlet; reset GFClCR 03/25 to 04/01 144.0 of 168.0 Trip of GFCI outlet; reset GFCICR 04/01 to 04/08 None Flow meter seized; estimated flow from run time and0.0 of 169.5 previous flow rateCR 07/01 to 07/08 79.5 of 167.4 Pump seized and blew fuse; replaced pumpPB 11/18 to 11/25 105.4 of 168.2 Trip of GFCl outlet; reset GFCI and replaced pumpDespite the lower-than-normal sampling volumes in the various instances involving powerinterruptions and equipment failures, required LLDs were met on 571 of the 571 particulate filters,and 571 of the 571 of the iodine cartridges collected during 2014. When viewed collectively duringthe entire year of 2014, the following sampling recoveries were achieved in the airborne samplingprogram:Location Recovery Location Recovery Location RecoveryWS 100.0% PB 98.2% PC 100.0%ER 99.9% OA 99.9% IVMS 100.0%WR 100.0% EB 99.9% EW 99.9%PL 100.0% CR 97.4%An alternate location had to be found for sampling control vegetable samples in the Bridgewaterarea. In past years, samples had been collected at the Bridgewater County Farm, associated withthe Bridgewater Correctional Facility. Due to loss of state funding for garden projects during 2006,no garden was grown. An alternate location was found at the Hanson Farm in Bridgewater, locatedin the same compass sector, and at approximately the same distance as the Bridgewater CountyFarm. Additional samples of naturally-occurring vegetation were collected from distant controllocations in Sandwich and Norton. As expected for control samples, vegetables and vegetationcollected at these locations only contained naturally-occurring radioactivity (Be-7, K-40, and Ac/Th-228).Some problems were encountered in collection of crop samples during 2014. Crops which hadnormally been sampled in the past (lettuce, tomatoes, potatoes, and onions) were not grown at thePlymouth County Farm (CF) during 2014. Leafy material from pumpkin plants and com plants weresubstituted for the lettuce to analyze for surface deposition of radioactivity on edible plants.Samples of squash, tomatoes, cucumbers, zucchini, and grape leaves were also collected from twoother locations in the immediate vicinity of Pilgrim Station. No radionuclides attributed to PNPSoperations were detected in any of the edible crop samples collected during 2014.Naturally-growing leafy vegetation (grass, leaves from trees and bushes, etc.) was collected nearsome gardens identified during the annual land use census. Due to the unavailability of crops grownin several of these gardens, these substitute samples were collected as near as practicable to thegardens of interest. No radionuclides attributed to PNPS operations were detected in any of thesamples. Additional details regarding the land use census can be found in Appendix C of this report.As presented in Table 2.9-1, several samples of naturally-occurring vegetation (leaves from trees,bushes, and herbaceous plants) were collected at a number of locations where the highestatmospheric deposition would be predicted to occur. Some of these samples indicated Cs-137 atconcentrations ranging from non-detectable up to 133 pCi/kg. The highest concentration of 133pCi/kg was detected in a sample of natural vegetation collected from the Pine Hills area of the PineHills south of PNPS. This Cs-1 37 result is within of the normal range of average values expected forPage 84 weapons-testing fallout (75 to 145 pCi/kg as projected from the pre-operational sampling program).It should be noted that natural vegetation samples collected in the 1990s often showed detectableCs-1 37 from nuclear weapons tests up into the range of 300 to 400 pCi/kg, whereas soil samplesoften indicated concentrations in excess of 2000 pCi/kg. Cs-137 has a 30-year half-life, andmeasureable concentrations still remain in soil and vegetation as a result of atmospheric nuclearweapons testing performed during the 1950s through 1970s. A review of effluent data presented inAppendix B indicates that there were no measurable airborne releases of Cs-137 from PilgrimStation during 2014 that could have attributed to these detectable levels. The sample with thehighest level of Cs-137 also contained high levels of AcTh-228, indicating appreciable soil contenton the natural vegetation. This sample of natural vegetation was analyzed "as is" without anymeasure to clean the samples as normally would be performed prior to consuming vegetables, andwould have detected any Cs-1 37 in soil adhering to those leaves collected. Certain species of plantssuch as sassafras are also known to concentrate chemical elements like cesium, and this higher-than-expected level is likely due to a combination of external soil contamination and bioconcentrationin the leaves of the plants sampled. These levels are not believed to be indicative of any releasesassociated with Pilgrim Station. No radioactivity attributable to Pilgrim Station was detected in any ofthe vegetable samples collected during 2014, and results of any detectable naturally-occurringradioactivity were similar to those observed in the preoperational monitoring program.The cranberry bog at the control location Pine Street Bog in Halifax was not in production during2014, so a sample could not be obtained from this location. A substitute control sample wascollected from a bog (Hollow Bog) in Kingston, beyond the influence of Pilgrim Station. In addition,the cranberry bog along Bartlett Road suspended operation during 2014, and was not producingcranberries. Samples were collected from a single indicator location located along BeaverdamRoad.Additional problems were encountered with composite water samples collected from the DischargeCanal. During the weeks of 14-Jan to 21-Jan-2014, and 20-Feb-2014 to 26-Feb-2014, cold weathercaused an ice blockage in the hose feeding water from the submersible pump in the DischargeCanal up to the sampling lab at the Pedestrian Bridge. Therefore, water flow to the sampler wasinterrupted for an unknown portion during each of these weekly sampling periods. No radioactiveliquid discharges were occurring during either of these two periods.Samples of blue mussels are normally collected twice each year in the spring and in the autumnfrom the vicinity of the Discharge Canal Outfall. Due to water scouring action from winter storms, nomussel samples were available for collection in the area during the April to June sampling period.Repeated and concerted efforts were made to collect these species, but failed to produce anysamples.Group I fishes, consisting of winter flounder or yellow-tail flounder are normally collected twice eachyear in the spring and in the autumn from the vicinity of the Discharge Canal Outfall. When fishsampling occurred in the September to November collection period, no samples of Group I fish couldbe collected, as the species had already moved to deeper water for the upcoming winter. Repeatedand concerted efforts were made to collect these species, but failed to produce any samples.Group II fishes, consisting of tautog, cunner, cod, pollock, or hake are normally collected once eachyear in the summer from the vicinity of the Discharge Canal Outfall. Recent declines in populationsof these species in the rock breakwater outboard of Pilgrim Station resulted in no sample beingcollected during 2014. Repeated and concerted efforts were made to collect these species, butfailed to produce any samples.Although a sample of Group III fishes (striped bass) was collected from the Discharge Canal Outfallduring the summer sampling season, no sample of Group III fishes was collected from a controllocation during the year. This was due to fishing restrictions, low numbers of target species, andPage 85 seasonal unavailability. Repeated and concerted efforts to catch the desired species failed toproduce any samples for the control location.In summary, the various problems encountered in collecting and analyzing environmental samplesduring 2014 were relatively minor when viewed in the context of the entire monitoring program.These discrepancies were promptly corrected when issue was identified. None of the discrepanciesresulted in an adverse impact on the overall monitoring program.Page 86 APPENDIX EENVIRONMENTAL DOSIMETRY COMPANYAnnual Quality Assurance Status ReportJanuary -December 2014 ENVIRONMENTAL DOSIMETRY COMPANYANNUAL QUALITY ASSURANCE STATUS REPORTJanuary -December 2014Prepared By:Approved By:K 1'IC---Date: d k Z (-jDate: s-Environmental Dosimetry Company10 Ashton LaneSterling, MA 01564 TABLE OF CONTENTSPaqeL IS T O F T A B L E S ....................................................................................................................... iiiEXECUTIVE SUMMARY ............................................................................................................ ivI.

Summary of Independent QC Results for 2014 5-iii-EXECUTIVE SUMMARYRoutine quality control (QC) testing was performed for dosimeters issued by the EnvironmentalDosimetry Company (EDC).During this annual period, 100% (72/72) of the individual dosimeters, evaluated against the EDCinternal performance acceptance criteria (high-energy photons only), met the criterion foraccuracy and 100% (72/72) met the criterion for precision (Table 1). In addition, 100% (12/12)of the dosimeter sets evaluated against the internal tolerance limits met EDC acceptancecriteria (Table 2) and 100% (6/6) of independent testing passed the performance criteria (Table3). Trending graphs, which evaluate performance statistic for high-energy photon irradiationsand co-located stations are given in Appendix A.Two assessments were performed in 2014, one internal and one external. There were nofindings.-iv-I. INTRODUCTIONThe TLD systems at the Environmental Dosimetry Company (EDC) are calibrated andoperated to ensure consistent and accurate evaluation of TLDs. The quality of thedosimetric results reported to EDC clients is ensured by in-house performance testingand independent performance testing by EDC clients, and both internal and clientdirected program assessments.The purpose of the dosimetry quality assurance program is to provide performancedocumentation of the routine processing of EDC dosimeters. Performance testingprovides a statistical measure of the bias and precision of dosimetry processing againsta reliable standard, which in turn points out any trends or performance changes. Twoprograms are used:A. QC ProgramDosimetry quality control tests are performed on EDC Panasonic 814Environmental dosimeters. These tests include: (1) the in-house testing programcoordinated by the EDC QA Officer and (2) independent test perform by EDCclients. In-house test are performed using six pairs of 814 dosimeters, a pair isreported as an individual result and six pairs are reported as the mean result.Results of these tests are described in this report.Excluded from this report are instrumentation checks. Although instrumentationchecks represent an important aspect of the quality assurance program, they arenot included as process checks in this report. Instrumentation checks representbetween 5-10% of the TLDs processed.B. QA ProgramAn internal assessment of dosimetry activities is conducted annually by theQuality Assurance Officer (Reference 1). The purpose of the assessment is toreview procedures, results, materials or components to identify opportunities toimprove or enhance processes and/or services.II. PERFORMANCE EVALUATION CRITERIAA. Acceptance Criteria for Internal Evaluations1. BiasFor each dosimeter tested, the measure of bias is the percent deviation ofthe reported result relative to the delivered exposure. The percentdeviation relative to the delivered exposure is calculated as follows:i 100Hiwhere:H' = the corresponding reported exposure for the ith-dosimeter (i.e., the reported exposure)H= the exposure delivered to the ith irradiateddosimeter (i.e., the delivered exposure)1 of 6

2. Mean BiasFor each group of test dosimeters, the mean bias is the average percentdeviation of the reported result relative to the delivered exposure. Themean percent deviation relative to the delivered exposure is calculated asfollows:where:H' = the corresponding reported exposure for the ithdosimeter (i.e., the reported exposure)Hi = the exposure delivered to the ith irradiated testdosimeter (i.e., the delivered exposure)n = the number of dosimeters in the test group3. PrecisionFor a group of test dosimeters irradiated to a given exposure, themeasure of precision is the percent deviation of individual results relativeto the mean reported exposure. At least two values are required for thedetermination of precision. The measure of precision for the ith dosimeteris:where:Hi = the reported exposure for the ith dosimeter (i.e., thereported exposure)H the mean reported exposure; i.e., H=- In = the number of dosimeters in the test group4. EDC Internal Tolerance LimitsAll evaluation criteria are taken from the "EDC Quality System Manual,"(Reference 2). These criteria are only applied to individual testdosimeters irradiated with high-energy photons (Cs-137) and are asfollows for Panasonic Environmental dosimeters: +/- 15% for bias and +/-12.8% for precision.2 of 6 B. QC Investigation Criteria and Result ReportingEDC Quality System Manual (Reference 2) specifies when an investigation isrequired due to a QC analysis that has failed the EDC bias criteria. The criteriaare as follows:1. No investigation is necessary when an individual QC result falls outsidethe QC performance criteria for accuracy.2. Investigations are initiated when the mean of a QC processing batch isoutside the performance criterion for bias.C. Reporting of Environmental Dosimetry Results to EDC Customers1. All results are to be reported in a timely fashion.2. If the QA Officer determines that an investigation is required for aprocess, the results shall be issued as normal. If the QC results,prompting the investigation, have a mean bias from the known of greaterthan +/-20%, the results shall be issued with a note indicating that theymay be updated in the future, pending resolution of a QA issue.3. Environmental dosimetry results do not require updating if theinvestigation has shown that the mean bias between the original resultsand the corrected results, based on applicable correction factors from theinvestigation, does not exceed +/-20%.Ill. DATA SUMMARY FOR ISSUANCE PERIOD JANUARY-DECEMBER 2014A. General DiscussionResults of performance tests conducted are summarized and discussed in thefollowing sections. Summaries of the performance tests for the reporting periodare given in Tables 1 through 3 and Figures 1 through 4.Table 1 provides a summary of individual dosimeter results evaluated against theEDC internal acceptance criteria for high-energy photons only. During this period,100% (72/72) of the individual dosimeters, evaluated against these criteria metthe tolerance limits for accuracy and 100% (72/72) met the criterion for precision.A graphical interpretation is provided in Figures 1 and 2.Table 2 provides the Bias + Standard deviation results for each group (N=6) ofdosimeters evaluated against the internal tolerance criteria. Overall,100%(12/12) of the dosimeter sets evaluated against the internal toleranceperformance criteria met these criteria. A graphical interpretation is provided inFigures 3Table 3 presents the independent blind spike results for dosimeters processedduring this annual period. All results passed the performance acceptancecriterion. Figure 4 is a graphical interpretation of Seabrook Station blind co-located station results.3 of 6 B. Result TrendingOne of the main benefits of performing quality control tests on a routine basis isto identify trends or performance changes. The results of the Panasonicenvironmental dosimeter performance tests are presented in Appendix A. Theresults are evaluated against each of the performance criteria listed in Section II,namely: individual dosimeter accuracy, individual dosimeter precision, and meanbias.All of the results presented in Appendix A are plotted sequentially by processingdate.IV. STATUS OF EDC CONDITION REPORTS (CR)No condition reports were issued during this annual period.V. STATUS OF AUDITS/ASSESSMENTSA.

Thisprogram encompasses radionuclides in water, soil, milk, naturally occurring radioactive isotopesin soil and air filters.GEL procures single-blind performance evaluation samples from Eckert & Ziegler Analytics to verify theanalysis of sample matrices processed at GEL. Samples are received on a quarterly basis. GEL'sThird-Party Cross-Check Program provides environmental matrices encountered in a typical nuclearutility REMP. The Third-Party Cross-Check Program is intended to meet or exceed the inter-laboratorycomparison program requirements discussed in NRC Regulatory Guide 4.15. Once performanceevaluation samples have been prepared in accordance with the instructions provided by the PTprovider, samples are managed and analyzed in the same manner as environmental samples fromGEL's clients.3. Quality Assurance Program for Internal and External AuditsDuring each annual reporting period, at least one internal assessment of each area of the laboratory isconducted in accordance with the pre-established schedule from Standard Operating Procedure for theConduct of Quality Audits, GL-QS-E-001. The annual internal audit plan is reviewed for adequacy andincludes the scheduled frequency and scope of quality control actions necessary to GEL's QA program.Internal audits are conducted at least annually in accordance with a schedule approved by the QualitySystems Director. Supplier audits are contingent upon the categorization of the supplier, and may ormay not be conducted prior to the use of a supplier or subcontractor. Type I suppliers andsubcontractors, regardless of how they were initially qualified, are re-evaluated at least once every threeyears.In addition, prospective customers audit GEL during pre-contract audits. GEL hosts several externalaudits each year for both our clients and other programs. These programs include environmentalmonitoring, waste characterization, and radiobioassay. The following list of programs may audit GEL atleast annually or up to every three years depending on the program.* NELAC, National Environmental Laboratory Accreditation Program* DOECAP, U.S. Department of Energy Consolidated Audit Program" DOELAP, U.S. Department of Energy Laboratory Accreditation Program" DOE QSAS, U.S. Department of Energy, Quality Systems for Analytical Services* ISO/IEC 17025:2005" A2LA, American Association for Laboratory Accreditation" DOD ELAP, US Department of Defense Environmental Accreditation Program* NUPIC, Nuclear Procurement Issues Committee" South Carolina Department of Heath and Environmental Control (SC DHEC)The annual radiochemistry laboratory internal audit (13-RAD-001) was conducted in July, 2014. One (1)finding, four (4) observations, and eight (8) recommendations resulted from this assessment. BySeptember, 2014, the finding was closed and appropriate laboratory staff addressed each observationand recommendation.

Performance Evaluation Acceptance Criteria for Environmental Sample AnalysisGEL utilized an acceptance protocol based upon two performance models. For those inter-laboratoryprograms that already have established performance criteria for bias (i.e., MAPEP, and ERA/ELAP),GEL will utilize the criteria for the specific program. For intra-laboratory or third party quality controlprograms that do not have a specific acceptance criteria (i.e. the Eckert-Ziegler Analytics EnvironmentalCross-check Program), results will be evaluated in accordance with GEL's internal acceptance criteria.5. Performance Evaluation SamplesPerformance Evaluation (PE) results and internal quality control sample results are evaluated inaccordance with GEL acceptance criteria. The first criterion concerns bias, which is defined as thedeviation of any one result from the known value. The second criterion concerns precision, which dealswith the ability of the measurement to be replicated by comparison of an individual result with the meanof all results for a given sample set.At GEL, we also evaluate our analytical performance on a regular basis through statistical processcontrol (SPC) acceptance criteria. Where feasible, this criterion is applied to both measures of precisionand accuracy and is specific to sample matrix. We establish environmental process control limits atleast annually.For Radiochemistry analysis, quality control evaluation is based on static limits rather than those thatare statistically derived. Our current process control limits are maintained in GEL's AlphaLIMS. We alsomeasure precision with matrix duplicates and/or matrix spike duplicates. The upper and lower controllimits (UCL and LCL respectively) for precision are plus or minus three times the standard deviationfrom the mean of a series of relative percent differences. The static precision criteria for radiochemicalanalyses are 0 -20%, for activity levels exceeding the contract required detection limit (CRDL).6. Quality Control Program for Environmental Sample AnalysisGEL's internal QA Program is designed to include QC functions such as instrumentation calibrationchecks (to insure proper instrument response), blank samples, instrumentation backgrounds,duplicates, as well as overall staff qualification analyses and statistical process controls. Both qualitycontrol and qualification analyses samples are used to be as similar as the matrix type of those samplessubmitted for analysis by the various laboratory clients. These performance test samples (orperformance evaluation samples) are either actual sample submitted in duplicate in order to evaluatethe precision of laboratory measurements, or fortified blank samples, which have been given a knownquantity of a radioisotope that is in the interest to GEL's clients.Accuracy (or Bias) is measured through laboratory control samples and/or matrix spikes, as well assurrogates and internal standards. The UCLs and LCLs for accuracy are plus or minus three times thestandard deviation from the mean of a series of recoveries. The static limit for radiochemical analyses is75 -125%. Specific instructions for out-of-control situations are provided in the applicable analyticalSOP.GEL's Laboratory Control Standard (LCS) is an aliquot of reagent water or other blank matrix to whichknown quantities of the method analytes are added in the laboratory. The LCS is analyzed exactly like asample, and its purpose is to determine whether the methodology is in control, and whether thelaboratory is capable of making accurate and precise measurements. Some methods may refer to these MLaboratories LLCP.O. Box 30712, Charleston, SC 294172014 ANNUAL QUALITY ASSURANCE REPORT Page 9 of 64samples as Laboratory Fortified Blanks (LFB). The requirement for recovery is between 75 and 125%for radiological analyses excluding drinking water matrix.Bias (%) = (observed concentration)

• 100 %(known concentration)Precision is a data quality indicator of the agreement between measurements of the same property,obtained under similar conditions, and how well they conform to themselves. Precision is usuallyexpressed as standard deviation, variance or range in either absolute or relative (percentage) terms.GEL's laboratory duplicate (DUP or LCSD) is an aliquot of a sample taken from the same container andprocessed in the same manner under identical laboratory conditions. The aliquot is analyzedindependently from the parent sample and the results are compared to measure precision andaccuracy.If a sample duplicate is analyzed, it will be reported as Relative Percent Difference (RPD). The RPDmust be 20 percent or less, if both samples are greater than 5 times the MDC. If both results are lessthan 5 times MDC, then the RPD must be equal to or less than 100%. If one result is above the MDCand the other is below the MDC, then the RPD can be calculated using the MDC for the result of theone below the MDC. The RPD must be 100% or less. In the situation where both results are above theMDC but one result is greater than 5 times the MDC and the other is less than 5 times the MDC, theRPD must be less than or equal to 20%. If both results are below MDC, then the limits on % RPD arenot applicable.Difference (%) = (high duplicate result -low duplicate result)

One analytical failure occurred: Americium-241 in water.For the corrective actions associated with MRAD-20, refer to CARR140520-874 which are detailed inTable 8.11. Summary of Participation in the ERA PT ProgramThe ERA program provided samples (RAD-96, RAD-98, and 01 1014L) for fifty (50) individualenvironmental analyses. Of the 50 analyses, 96.0% (48 out of 50) of all results fell within the PTprovider's acceptance criteria. One isotope failure occurred: Strontium-89 in water.For the corrective actions associated with RAD-98 refer to corrective actions CARR140825-902 (Table8).12. Corrective Action Request and Report (CARR)There are two categories of corrective action at GEL. One is corrective action implemented at theanalytical and data review level in accordance with the analytical SOP. The other is formal correctiveaction documented by the Quality Systems Team in accordance with GL-QS-E-002. A formal correctiveaction is initiated when a nonconformance reoccurs or is so significant that permanent elimination orprevention of the problem is required. Formal corrective action investigations include root causeanalysis.GEL includes quality requirements in most analytical standard operating procedures to ensure that dataare reported only if the quality control criteria are met or the quality control measures that did not meetthe acceptance criteria are documented. A formal corrective action is implemented according to GL-QS-E-002 for Conducting Corrective/Preventive Action and Identifying Opportunities for Improvement.Recording and documentation is performed following guidelines stated in GL-QS-E-012 for Client NCRDatabase Operation.

N Laboratories LLCP.O. Box 30712, Charleston, SC 294172014 ANNUAL QUALITY ASSURANCE REPORT Page 11 of 64Any employee at GEL can identify and report a nonconformance and request that corrective action betaken. Any GEL employee can participate on a corrective action team as requested by the QS team orGroup Leaders. The steps for conducting corrective action are detailed in GL-QS-E-002. In the eventthat correctness or validity of the laboratory's test results in doubt, the laboratory will take correctiveaction. If investigations show that the results have been impacted, affected clients will be informed ofthe issue in writing within five (5) calendar days of the discovery.Table 8 provides the status of CARRs for radiological performance testing during 2014.

The QAO inadvertently entered the incorrect activityfor this parameter when she was entering the results on theMAPEP website. 0.261 ug/sample instead of 0.0261ug/sample was entered. The data entry error was not caughtduring the GL review process. MAPEP results only are peerreviewed by the GL of the applicable area to ensure that thedata was entered correctly.A second PT was successfully analyzed for this matrix.Uranium-234/233, and Uranium-238 in soil by AlphaSpec:Following reviews of our process and data and conversationswith personnel from the affected laboratories, it wasdetermined that all failures were due to an incomplete sampledigestion. A total digestion technique using Hydrofluoric Acidwas performed on the sample. However, this digestion wasnot vigorous enough to extract all the U-234 and U-238 fromthe soil because the analytes were fused into the soil at anextremely high temperature. Due to the high number of labsthat received a Not Acceptable rating for this analysis,MAPEP has posted an explanation on the preparation of theUranium Soil standard on their website.Permanent Corrective/Preventive Actions orImprovements:Upon notification of the failure, the sample was re-digestedusing a Sodium Hydroxide fusion method prior to ion-exchange separation chemistry. The results for both the U-234 and U-238 fall within acceptable range. In the future, allMAPEP soil samples will be analyzed with a NaOH fusiondissolution technique. Our analytical procedures provide theflexibility to Derform different extraction techniques (leachina.

The batch quality control samples were reviewedand found to be compliant. The recoveries in theLaboratory Control Sample (LCS) recovered at98.2%. Two sample duplicates were also preparedin the batch. The RPDs were 4.8 and 8.6.2. The sample was re-analyzed in duplicate after thereport was received. One with our normal Am-243tracer, and another with Cm-244 tracer. Both of thereanalysis confirm the original reported result (whichis outside the range of acceptable results).Control charts for all Am tracer recoveries were also reviewedto determine if there may be an issue with the tracers. Whilethere is a slight bias in the average LCS recovery, it was notsignificant enough to consider abnormal, and did not comeclose to accounting for the high result on this analysis.Additionally, since the sample was reanalyzed using twodifferent tracers and achieved the same result, a tracer issuewas ruled out as the potential culpritPermanent Corrective/Preventive Actions orImprovements :The laboratory must assume unidentified random errorcaused the elevated bias because all quality control criteriawere met for the batch. Additionally, a well characterizedperformance evaluation sample from another vendor wasprepped and analyzed a few weeks after this sample. TheAm-241 recovered at 105% for this sample and fell well withinits acceptance range.A second PT was successfully analyzed for this matrix.

While the LCS recoveredoutside to its acceptance range, the matrix spike (MS)recovery fell within both the acceptance range for the MS(80%-120%) and the acceptance range for the LCS (90%-110%). The result was also confirmed using Method LABPBMS-A-004.
