SUMMARY

AND CONCLUSIONS The operation of a nuclear power plant results in the release of small amounts of radioactive materials to the environment. A radiological environmental monitoring program (REMP) has been established to monitor radiation and radioactive materials in the environment around the Oyster Creek Nuclear Generating Station (OCNGS). The program evaluates the relationship between amounts of radioactive material released in effluents to the environment and resultant radiation doses to individuals. The radiological environmental monitoring performed by the GPU Nuclear Environmental Controls Department for 1986 is discussed in this report. Summaries and interpretations of the data are published annually. Additional information concerning releases of radioactive materials to the environment is contained in the Semiannual Effluent Reports submitted to the United States Nuclear Regulatory Commission.

During 1986 the radioactive liquid and gaseous effluents associated with OCNGS were a small fraction of the applicable federal regulatory limits and have not had significant or measurable ef fects on the quality of the environment. Estimated radiation doses to the public attributable to 1986 operations at OCNGS were well below all applicable regulatory limits and were significantly less than doses received from common sources of radiation. Similar conclusions were reached in previous reports.

Because most of the radioactive materials considered in this report are i normally present in the environment, either naturally or as a result of 1

non-0CNGS activities such as atmospheric nuclear weapon testing, measurements made in the vicinity of the site were compared to cackground measurements. Samples of air, su rf ace water, soil and sediment, shellfish, fish, vegetation, groundwater, and precipitation were i

j collected. External penetrating radiation dose measurements also were f made in the vicinity of CCNGS. Samples were analyzed for radioactivity f including tritium (H-3), gross beta and gross alpha (suspended and dissolved fractions in water), strontium-89 (St-89) and 90 (St-90),

Radium-226 (Ra-226), Uranium, and gamma-emitting radionuclides. The results of environmental measurements are used to assess the environmental impact of OCNGS operations, to demonstrate compliance with the Technical Specifications and applicable federal regulations, and to verify the adequacy of containment and radioactive effluent control systems. The data collected by the REMP provide a historical record of the levels of radionuclides and radiation attributable to natural causes, worldwide fallout from prior nuclear weapons tests, the Chernobyl incident, and OCNGS operations. Radiological impacts in terms of radiation dose as a result of OCNGS operations were calculated and also are discussed. The results provided in this report are summarized in the following highlights.

. During 1986 there were over 1750 samples taken from the aquatic, atmospheric, and terrestrial environments around OCNGS. More than 5200 analyses were performed on these samples.

, In addition to natural radioactivity, low ' levels of fission products such as St-89, St-90, cesium-134 (Cs-134), cesium-137

( Cs -137 ) , cerium-141 (Ce-141), ruthenium-103 (Ru-103), and iodine-131 (I-131) were detected in various media and were attributed to fallout from prior nuclear weapons testing and the Chernobyl accident. Clam and sediment samples also located in and immediately downstream of the Oyster Creek discharge canal contained low levels of Co-60, as documented in previous semiannual reports.

. Dose rates measured with TLDs around OCNGS were consistent with historical natural background radiation.

. All radioactive effluent releases were small fractions of the federal regulatory and Technical Specification limits. The predominant radionuclides released were xe non -135 (Xe-135) in gases and H-3 in liquids.

, 1

. Operations at OCNGS during 1986 caused radiation doses to the public sell below all applicable regulatory limits, and significantly less than doses received from other common sources of radiation. The maximum whole body exposurer potentially received by an individual from liquid and gaseous ef fluents was conservatively calculated to be about 4.3 :rRem total.

INTRODUCTION Background information is provided on basic radiation characteristics, plant operations, radioactive effluent controls, and environmental monitoring to assist the reader in reviewing this document.

Characteristics of Radiation Atoms whose nuclei contain an excess of ene rgy are called radioactive atoms. They release this excess energy by expelling electromagnetic or particulate radiation from their atomic centers to becoma stabli (non-radioactive). This process is called ' radioactive decay.'

Electromagnetic radiation is x-rays and gamma rays and is similar in many ways to light waves, microwaves, and radiowaves. Particulate radiation may be either electrically charged such as alpha and beta particles or have no charge ( r.eut r on s ) . The term ' half-life' refers to the time it takes for one half of a given amount of a radionuclide to decay. Some radionuclides have a half-life as short as a fraction of a second while others have half-lives as long as millions of years. Each radionuclide has unique decay characteristics in terms of its energy, the types of radiation emitted, and its half-life. Radionuclides may decay di r ec tly into stable elements or may undergo a series of decays which ultimately reach a stable element. Radionuclides are found in nature (e.g. U-235, Th-228, and K-40), and may also be produced artificially such as with accele rators and nuclea r reactors (e.g. , I-131, Cs-137, and Co-60).

The activity of a radioactive source is the number of nuclear disintegrations (decays) of the source per unit of time. The unit of activity is the curie. A one-curie radioactive source undergoes 2.2 trillion disintegrations per minute; but in the realm of nuclear power plant effluents and environmental radioactivity, this is a large unit.

So, two fractional units--the microcurie and the picoeurie--are more commonly used. The microcurie is one millionth of a curie and represents 2.2 million decays per minute. The picoeurie is one millionth of a microcurie and represents 2.2 decays per minute. The mass of a 4

l

radionuclide corresponding to one curie is directly proportional to the half-lif e and the atomic weight of the nuclide. For example, uranium-235 (U-235) with a half-life of 7810 million years requires about 465,000 grams to obtain an activity of one curie. The mass-activity relationship for I-131 with a half-life of 8.0 days requires about 8 millionths of a gram to produce a curis.

Any mechanism that can supply the energy necessary to ionize an atom, break a chemical bond, or alter the chemistry of a living cell is capable of producing biological damage. Electromagnetic and particulate radiation can produce cellular damage by any of these mechanisms. In assessing the biological ' ef f ects of radiation, the type, energy, and amount of radiation must all be considered.

Total body radiation involves exposure of all organs. Most oackground exposures 'are of this form. When radioactive elements enter the body through inhalation or ingestion, their distribution is not uniform. For example, radiciodine selectively concentrates in the thyroid gland, whereas radiocesium collects in muscle and li ve r tissue and radiostrontium in mineralized bone. The total dose to organs by a given radionuclide is also influenced by the quantity and the duration of time that the radionuclide remains in the body. Owing to their rapid radioactive decay as well as their removal from the body, certain radionuclides stay in the body for very short times while some remain for years.

The amount of radiation dose which an individual receives is most frequently expressed in rem. Since human exposure to radiation usually involves very small exposures, the millitem (mrem) is most commonly used (1 mrem = 1/1000 rem). Sometc.es, it is desirable to express the collective radiation dose to a population. Such a collective dose is expressed in person-tem, which is calculated by adding up each individual dose (e.g., 1 rem to each of 100 persons = 100 person-tem).

Sources of Radiation Excosure Many sources of radiation exposure exist. The most ubiquitous and least controllable sou rce is natural background radiation f rom cosmic rays and terrestrial radioactivity which humanity has always lived with and always will. There is no choice. Every second of our lives, over 7,000 atoms undergo radioactive decay in the body of the average adult.

Radioactive elements have always been a part of our planet and everything which has come from the earth including our own bodies is, therefore, naturally radioactive. Radioactive materials found in the earth's crust today consist of such radionuclides as potassium-40 (K-40), uranium-238 (U-238), thorium-232 (Th-232), radium-226 (Ra-226), and radon-222 (Rn-222). These radionuclides are introduced into the water, soil, and air by such natural processes as volcanoes, weathering, erosion, and radioactivity decay.

Some of the naturally occurring radionuclides such as radon are a significant source of radiation exposure to the general public.

Radioactive radon is an inert gas produced naturally in the ground as a part of the uranium and thorium decay series. Radon continues to undergo radioactive decay, producing new naturally radioactive materials called

' radon daughte rs' . These new materials, which are solid particles--not gases--can stick to surfaces cuch as dust particles in the air.

Concentrations of radon in air are variable and affected by concentrations of uranium and thorium in soil, altitude, soil porosity, temperature, pressure, soil moisture, rainfall, snow cover, atmospheric conditions, and season. It can move through cracks and openings into basements of buildings and become trapped in a small air volume indoors.

Thus, indaor radon concentrations are usually higher than those found outdoors. Building materials such as cinder block and concrete are radon sources. Radon can also be dissolved in well water and contribute to airborne radon in houses when released through showers or washing.

nust containing radon daughter particles can be inhaled arid deposit.ed on

the surface of an individual's lung. Radon daughters emit hiqd energy alpha rad'.atten to the lung lining resulting in an average dose to the lungs in the United States of 3000 mrem (3 rem) per year. In areas such as northwestern New Jersey over a geologic formation known as the Reading J

Prong, these levels are even higher due to natural deposits of uranium.

, Here natural evposure le vels to the lung much higher than 3000 maem/ year have been recorded. Doses resulting from raden and its d tughter products are the highest contributor to individuals f rom all natural sources.

Abo'at 300 cosmic cays originating from outer space pass through each person every seconC. The interaction of cosmic rays with atoms in the earth's exosphere produces radionuclides such as beryllium-7 (Be-7),

be ryllium .1 C (Be-10), carbon-14 (C-14), tritium (H-3), and sodium-22

~

(Na-22). Portions of t~nese radionuclides o'ecome ceposited on land and 3 wate r surf aces wnile the re*.ainde r stay suspended in tihe atmosphere.

Thus, there are natural radiaactive materials in the soil, water, air and

? building rc.a te r i s t s which corztt aute to radiatica doses to the human b.:,d y . Natural drinking water contains trace amounts of uranium and radi um ; milk con t.ti n s radicartive potassium. Sources of natural radiatio 7 and their average contributing radiation doses are summarized in Tacle 1. Radiation exposure Isvels from natural radiation fluctuate with time and also can vary widely from location to location. The a've rige individus1 in the United States receives approximately 100 mrem

• * ~

i per year from racural cources. In sone areas of the country, the dose from natural radiation is significantly higher. Residents of Colorado receive an additional 80 mrem per year dce to the increase in cosmic

, (higher elevation) and te rr est rid radiatic. le ve ls . In fact, for every 100 feet in elevition toove sea levei, an indi v idual will receive an j

additional 1 maem per year from conmic r ad ir.t ion. In se ve ral areas of l tne world, high concenter. tons of mineral deposits give natural background radiation levels of several tho.2 sand mrem per year.

In addition to natural background radiation, the average individual is exposed to radiation from a number of man-made sou rce s. The single largest of these sources comes from medical diagnosis, X-rays, CAT-scans, fluoroscopic ex amination and radio-pharmaceuticals. Approximately 160 million people in the United States are exposed to medical or dental X-rays in any given yea r. The annual dose to an individual from such irradiation averages 90 mrem or is approximately equal to the sum total of natural radiation. Smaller doses from man-made sou rces come from consumer products (television, smoke detectors, fertilizer), fallout from prior nuclear weapons tests and production of nuclear power and its associated fuel cycle.

Nuclea r fission is a process in which Pea vy atoms such as uranium are split into lighter fragments, many of which are radioactive. This process also results .n the release of large amounts of energy which can be used to generate electricity. There is scientific evidence that the nuclear fission process also occurs naturally.

Fallon co.uonly refers to the radioactive debris that settles to the surface of the earth following the detonation of nuclear weapons.

Fallout can be washed down to the earth's bu rf ace by rain or snow and is dispersed throughout the environment. There are approximately 200 radionuclides produced in the nuclear weapon detonation process; a number of these are detected in fallout. The radionuclides found in fallout which produce most of the fallout radiation exposures to man are I-131, l St-89, S t -9 0, and Cs 137.

Description of the Oyster Creek' Site General Information The Oyster Creek Nuclear Generating Station (OCNGS) has generated electricity since December, 1969. The operating license permits station operatior. up to a power level of 1930 megawatts (thermal) at a levelized, installed annual capacity of 620 megawatts (electrical).

The Oyster Creek Nuclear Generating Station is located in Ocean County, New Jersey, 2 miles inland from Barnegat Bay (Figure 1). The 1416-acre site is owned by - the applicant. It is situated partly in Lacey Township and, to a lesser extent, in Ocean Township. The site is about 60 miles South of Newark, 9 miles south of Toms River and 35 miles north of Atlantic City. The Garden State Parkway bounds the site on the west.

Overland access to the site is provided by U. S. Route 9, passing through the site and separating a 661-acre eastern portion from the balance of the p.operty west of the highway. The station is about 1/4 mile west of the highway and 1-1/4 miles east of the parkway. The site property extends about 3-1/2 miles inland from the bay; the maximum width in the north-south direction is almost 1 mile. Figure 1 relates the site to the more pertinent features of the county, as well as indicating the . location of the majority of Oyster Creek REMP stations.

areas. In addition to the resident population, a sizeable seasonal influx of people occurs during the summer. This influx resides almost excl'usively along the waterfront.

were from the northwest and west-northwest. In addition, there was a slightly increased component of wind direction f rom the south-southwest.

This indicates an early transition of weather patterns from the winter to the summer months. The normal northwest wind 3trection is expected as the winter months are dominated by Canadian air masses. From April through June, the wind directions were evenly divided between the northwest / west-northwest and southwest / south-southwest sectors. This defines the second half of the pe riod as the transition months between the winter and summer seasons. Summer months usually have the pesiominant wind direction from the southwest and south. During the July through September period, the predominant wind direction was from the west and southwest. Winds from the west are characteristic of a modified continental polar air mass that follows cold frontal passages. Winds from the southwest are usually associated with maritime tropical air normally present prior to cold frontal passages. The most frequent wind direction was from the south and is the end result of the sea-breeze phenomenon. At the he ig ht of this mesoscale effect (approximately 2:00 to 4:00 in the afternoon) the wind will parallel the coast - the result created f rom uneven heating between land and sea coupled with the natural rotation of the earth. The period from October through December is usually described as a transition period between the previously described summer patterns and those found in winter (winds f rom the west-northwest and no rth) . However, the entire second quarter was slightly cooler than usual and represents those conditions found during the winter months.

~

The wind direction during the latter three :Eonths was from the northwest.

• Other characteristics for the second half of 1986 include a small maxima of wind direction from the northeast, especially from October through December. This is due to the airflow around large high pressure systems. Periods with this onshore f etch have characte ristic low clouds, d rizzle and fog (stable atmospheres) .

A total of 51.33 (water equivalent) inches of precipitation fell during 1986, which amounts to approximately 8 inches above the annual average.

Lower than normal precipitation levels were recorded during the first three months of the reporting period (Figure 3). The reference data were

obtained from the closest and most accurate National Weather Service station located in Atlantic City, NJ. Recent comparison studies have shown close similarities of hourly meteorological data between the Oyster Creek and Atlantic City sites. There was a lack of late winter precipitation events during this first quarter. For the period of April through June, April and June were the wettest months (4.06 and 4.05 inches, respectively) while May was the driest month with only 0.86 inches of rainfall recorded. Normal May rainfall is approximately 3.4 inches.

Precipitation during this latter half of the second quarter was primarily due to thundershower activity. Other rainfall activity did not reach the site due to the stabilizing effect of the Jea-breeze, common in the month of June and throughout the summer. Due to tais highly, stable weather phenomenon, showers build up to the west, move east-no rtheastwa rd, then become stagnant and eventually decay up to 15 miles inland. Only one major storm oucurred during the period, that being in mid-April, which deposited 3.48 inches of precipitteion on the site over two days.

For the pe riod of July .through Decembe r , precipitation was above normal (36.30 inches). The six-month average total from the  ?.:. la n t ic City National Neather Service historical record is 22.0 inches. During summer months precipitation is generally characterized by events of short duration but strong intensity (convective showers). Nich this type of precipitation event, there will be increased particulate fallout (washout) from the atmosphere, which has implications for radionuclide deposition. During the summer, marine air, which is stable, sill suppress i

generally these convective-type storms and decrease precipitation at most coastal locations. The sea-breeze can produce the This effect can occur along the coast up to 12 miles inland.

I same result. l l

Rainfall events during the six-month pe riod we re, for the most part, due I to extratropical storms of light to moderate intensity and long duration, especially during the second qua rte r.

EPPLUENTS Limits Radioactive effluent releases at OCNGS are under the jurisdiction of the United States Nuclear Regulatory Commission (USNRC). Since its inception, the USNRC (previously known as the Atomic Energy Commission -

AEC) has depended upon the recommendations of the International Commission on Radiological Protection (ICRP) established in 1928 the National Council on Radiation Protectior and Measurements (NCRP) established in 1929, and since 1939, the Federal Radiation Council (FRC)

(incorporated in the United States Environmental Protection Agency in 1970) for basic radiation protection standards and guidance. These guides and recommendations form the basis for the Nuclear Regulatory Commission's regulation in Title 10 of the Code of Federal Regulations Part 20, (10 FR 20), "Standards for Protection Against Radiation' used in the regulatory program for the commercial nuclear power industry. One recommendation of the ICRP, NCRP, and FRC is that radiation exposures should be mair.tained at levels which 'a re as low as reasonably achievable (ALARA) commensurate with the societal benefit derived from the activities resulting in such exposures. This philosophy was incorporated into the numerical guidelines of Appendix I to 10 CFR 50 and was adopted by GOU Nuclear.

~

Technical S pec if ic ations imposed by the NRC as a condition of the operating license, govern the operating requirements of the plant including the effluent control program. These requirements include I J operation of gaseous and liquid processing systems, installation and operation of radiation monitoring systems, establishment ot an inplant and environmental sampling and an91/ sis program, establishment ot a quality assurance program for effluents, procedures covering all aspects of effluents, and calculation of doses to the public.

Table 2 outlines the OCNGS effluent technical specifications. Note that an amendment to these technical specifications was made on November 20, 1986.

Sources of Radioactive Liquid and Gaseous Effluents At the Oyster Creek Nuclea r Generating Station, most of the fission products are retained within the fuel and fuel cladding. However small amounts of radioactive fission products are able to diffuse or mig r ate through the fuel cladding and into the reactor coolant. Trace quantities of the component and structure surf aces which have been activated, also get into the reactor coolant water. Many of the soluble fission and activation product levels such as radioactive iodines, strontiums, cobalts, and cesiums are greatly reduced by demineralizers in the purification system of the coolant. The noble gas fission products has a very low soluollity in the coolant and cannot be removed by the demineralizers. Instead they are given off as gas when the coolant is depressurized and are collected by a system designed for gas collection, holdup and emission. This represents 'the principal source of gaseous effluents.

Minute drainage of radioactive liquids from valves, piping, and/or equipment associated with the coolant system may occur in the Reactor, and/or Turbine Buildings. The noble gases become part of the gaseous wastes while the remaining radioactive liquids are collected in floor and equipment drains and sumps and are pumped to and processed in the Radwaste Sailding. Water processed in the radwaste facility that does not meet strict chemical specifications for primary system reuse becomes the sou rce of liquid ef fluents.

Radioactivity Removal from Liquid and Gaseous Wastes f At the Oyster Creek Nuclear Generating Station, radioactive liquid and gaseous wastes are collected, stored, and processed through processing systems to remove or reduce most of the radioactivity (exclusive of l tritium) prior to reuse within the plant or discharge to the environment. These processing systems are required by the Technical Specifications to be installed and operable and help to ensure all releases of radioactive liquid and gaseous effluents are as low as reasonably achievlole.

l

The liquid waste processing system receives water contaminated with radioactivity and processes it by filtration, demineralization, and distillation. Purified radwaste water is recycled to the plant.

Occasionally, it is necessary to discharge this purified water to the environment. Contaminants removed during the purification process are disposed of via the solids disposal systems. When purified water is discharged to the environment, it is first sam p led , analyzed, assigned a release rate, and then discharged to a receiving stream which has a flow rate of 460,000 to 960,000 gallons per minute.

Reactor of f-gas, consisting primarily of hydrogen and radioactive non-condensable gases, is withdrawn from the reactor primary system by steam jet air ejectors. These air ejectors drive the process stream through a 60 minute holdup pipe at approximately 110 cubic feet per minute and then into the Augmented Off-Gas (A0G) System. The holdup pipe allows radionuclides with short half-lives to decay. The Augmented Off-Gas System is a gaseous processing system which provides hydrogen conversion to water via a catalytic recombiner, removes the water (vapor) from the process stream, holds up the process stream to allow further decay of sho r t-li ved nuclides, and filters the off-gas using charcoal ceds and High Ef ficiency Particulate (HEPA) filters prior to discharge to the stack.

Once the process stream enters the stack, it is diluted by building ventilation, which averages 200,000 cubic feet per minute, is monitored and sampled, and then is discharged out the top of the 368-foot stack.

The Augmented Off-Gas System is a series of complex smaller systems which, when operating at optimum, reduce radioactive off-gas emission to near background. A single component failure within the A0G can cause system isolation which results in reactor off-gas oeing discharged from the end of the holdup pipe to the stack. When A0G isolation occurs, the activity released out of the stack increases. The Augmented Off-Gas System is typically valved in and out of the reactor gaseous process i stream during startups and shutdowns at approximately 40% power.

J

Ventilation from two buildings (A0G and turbine) does not discharge to the elevated stack and exhausts to the environment via roof vents. These systems are designed to maintain suitable ambient conditions for personnel and equipment. Each vent is monitored for noble gas, iodine, and particulate activity using in-line monitors and grab samples.

Effluent Data Radioactive liquids and gaseous releases from OCNGS did not exceed Federal regulatory and Technical Specification limits during 1986.

Radiological releases from OCNGS are calculated from installed plant effluent monitor readings and sample analyses for gaseous and liquid discharge points. These methods provide a means for accurate determination of the type and quantities of radioactive materials being released to the environment.

Nine radioactive liquid releases totalling '177,000 gallons were made from the OCNGS in 1986. The total radioactivity released to the environment was 1.07 curies of Tritium and 0.00135 curies of dissolved and entrained gases. Gaseous releases during 1986 resulted in 76,737 curies of fission and activation gaces, 0.62 curies of Iodine-131, 0.078 curies of particulate nuclides with half-lives greater than 8 days, and 19.27 curies of rritium being discharged to the environment. For each category, these releases were well within the regulatory limits specified in sections 3.6 and 4.6 of the OCNGS Technical Specifications.

Table 3 presents a brief operations summary for 1986.

RADIOLOGICAL ENVIRONMENTAL MONITORING Prog ram Design The radiological environmental monitoring program (REMP) was established at Oyster Creek to monitor radiation and radioactive materials in the environment and to evaluate the relationship between amounts of radioactive material released in etfluents and resultant radiation doses to individuals from principal pathways of exposure. The Oyster Creek Technical Specifications requite this p rog ram to be implemented. The Oyster Creek REMP meets all these requirements and in most cases far exceeds them.

The Oyster Creek REMP was designed on the basis of USNRC regulatory guides along with the USNRC Radiological Assessment 3ranen Technical Position on Environmental Monitoring. The important ob j ec ti ves of the REMP are:

, assessing dose impacts to the public from OCNGS operations

, verifying in-plant controls for the containment of radioactive materials o monitoring to determine buildup of long -li ved radionuclides in the environment and changes in background radiation levels

, providing reassurance to the public that the program is capable of adequately assessing impacts and identifying noteworthy l

changes in the radiological status of the environment.

L Published information concerning amounts of principal radionuclides released to the environment in liquid and gaseous effluents and data on distribution of radionuclides in environmental media can be used to determine the population critical exposure pathways that should be monitored and to identify media in which there is potential For long-term buildup of radioactivity.

The program consists of collecting samples from the environment, analyzing them for radiation and radioactivity content, and interpreting the results. With emphasis on the critical pathways to man, sampling consists of five general types of monitoring: atmospheric-radiation, fallout, domestic water, su rf ace water, and marine life. These samples include, but are not limited to, air, soil, surface water, fin fish, shellfish, marine sediment, vegetables, groundwater, and precipitation.

Thermoluminescent dosimeters (TLDs) are placed in the environment to measure ambient gamma radiation le vels . The Oyster Creek Technical Specifications Of fsite Dose Calculation Manual (ODCM) and recommendations from the scientific staff at Oyster Creek Environmental Controla Department specify the sample types to be collected and appropriate analyses.

On No vembe r 20, 1986 new technical specifications were implemented for Oyster Creek's REMP by the USNRC. Changes were brought about in Oyster Creek's REMP as a result of this. However, tn practice, the actual program conducted at Oyster Creek far exceeds that required by the technical specifications. Throughout this document, where appropriate, the reader will see tables and figures referring to pre- and post-Novembe r 20, 1986. This is to reflect the changes made in REMP. To ensure compliance with the technical specifications both bef ore and af ter the aforementioned date, REMP data .s summarized for both tech spec requirements.

Sampling locations have oeen established by considering meteorology, population distribution, hydrology, and land use characteristics of the local area. The sampling locations are divided into two classes, indicator and background. Indicator locations are those which are expected to show that plant effects, if any, exist. These locations were primarily selected on the basis of where the highest predicted environmental concentrations would occur. While the indicator locations

, are typically within a few miles of the plant, the background stations are generally at le as t 10 miles from the plant and some as far away as 35 miles. Therefore, background samples are collected at locations which M

should be unaffected by plant operations. They provide a basis on which to evaluate fluctuations at indicator locations relative to natural background radiation and radioactivity and fallout from prior nuclear weapon tests. Figures 1 (page 10) and 2 show the sampling locations of the Oyster Creek REMP, while a description of each location is outlined in Table 4.

In addition to specifying the minimum media to be collected and the minimum number of sampling locations, the rechnical Specifications also specify the frequency of sample collection, the types of analyses to be performed, and the analytical sensitivity (detection limit) and repo rting levels. Tables 5 and 6 provide a summary of the sample type, analyses performed, collection frequency, and number of sampling locations and type of analysis. Table A-1 in Appendix A presents problems encountered in the sample collection process. Sample analyses which did not meet the required analytical sensitivity are presented in Appendix B. Reporting level violations (effective tiovember 20, 1986) are reported in Appendix C.

The analytical results are routinely reviewed by environmental scientists at Oyster Creek to assure that sensitivities have been achieved and that the proper analyses have been performed. Investigations are conducted when activities fall outside ranges previously determined based upon historical data or when anomalous values are discovered. These ranges are purposely set narrow so that corrective action can be initiated before a reporting level is reached.

Procedures were written and approved by Environmental Controls, Quality Assurance, and the Contractor laboratories to cover all aspects of the radiological environmental monitoring program. These procedures cover such areas as sample collection, sampling equipment calibration and

_ maintenance, laboratory analysis, and data review.

Because of low radionuclide concentrations in environmental media, l special analysis techniques have been developed. Analytical laboratories contracted by GPU tiuc le a r use state-of-the-art la bo rato ry equipment t

Quality Assurance Program The quality assurance program associated with the Radiological Environmental Monitoring Program (REMP) at the OCNGS is governed and documented by written policies, procedures and records in accordance with Regulatory Guide 4.15, "Quality Assurance for Radiological Monitoring Programs". All procedures associated with sampling, packaging, shipment and storage of samples were developed to ensure sample integrity from the time of collection to the time of analysis. Each laboratory contracted to provide analytical services maintains a quality assurance program in accordance with the requirements of Reg. Guide 4.15. Each laboratory submits a quality assurance program document with revisions as necessary to the OCNGS Environmental Controls Departmeat for review to ensure that program requirements are satisfied.

The Quality Assu rance Program is composed of the f ollowing :

REMP QA SAMPLING PROGRAM The number and frequency of REMP quality control samples are listed on Table 7 for the ptriod January 1, 1986 through November 19, 1986 and on Table 8 for the period Nosember 20, 1986 through Decembe r 31, 1986. The major difference in these two tables is the total number of regular sampling locations for selected media resulting from the implementation of revised Environmental fechnical Specifications'on Nov. 20, 1981. ~Ea'ch of these samples, with the exception of the TLD's, are divided into three equal subsamples with two samples forwarded to the primary contractor laboratory for analysis having one designated as a blind sample. The ocher subsample is forwarded to the independent QA contractor la bo r a to ry for analysis. Ana lytical results from each laboratory are evaluated to determine acceptable agreement. If evaluation results in the determination tha* the result's are in non-agreement, than reanalyzing or recounting the samples may result. This system of dividing each sample into three subsamples provides both intralaboratory and interlaboratory comparison.

INTRALABORATORY ANALYSES The primary analytical laboratory performs duplicate analyses on every tenth sample. The number of duplicate analyses performed during 1986 are listed by media on Table 9. Intralaboratory analysis of both blank and spiked samples also are performed on a routine basia. The results of all of these analyses are reported on a bimonthly basis as well as results of detector backgrounds and efficiencies. Review of data produced by this program and the REMP QA S ampling Program discussed above indicate satisf actory performance by both contracted laboratories during 1986.

US EPA CROSS-CHECK PROGRAM Each laboratory contracted to perf orm analytical services participate in the EPA's Environmental Radioactivity La bo r ato ry Intercomparison Studies

( Cross -Chec k ) Program. Results of this program are included as Appendix D.

AUDITS Each contracted laboratory is audited by GPUN personnel on a routine basis to ensure compliance with contractual, procedural and regulatory requirements.

DIRECT RADIATION MONITSRING Dose rates f rom external radiation sources were measured at a number of locations in the vicinity of OCNGS using thermoluminescent dosimeters (TLDs). Naturally occurring sources, including radiation of cosmic origin and natural radioactive materials in the air and ground, is well as fsllout from prior nuclear weapons testing, resulted in a certain amount of penetrating radiation oeing recorded at all monitoring locations. Indicator TLD's dere placed systematically in sectors of predominant wind direction at the atte boundary, 1 mile, 1 miles, 5 miles, and 8 miles distant from the site. Background TLDs were located in locations typically greater than ten miles distance from OCNGS. Until December 1, 1986, film badges were aJso used, as they were previously required by f ormer tech. specs. The results of their exposure are shown in Table 10.

Sample Collection and Analysis A state-of-the-art thermoluminescent dosimeter is used in Oys p Creek's REMP. Thermoluminescence is a process in which ioni3ing radiation, upon interacting with the sensitive material of the TLD (the phosphor or

' element') causes come of the energy deposited in the phosphor to be storea in stable ' traps' in the TLD Material. These TLD traps are so stable that they do not decay aprreciably over the course of months or even years. This provides an e x c e lle n'. method of integrating the exposure received over a pariod of time. *he energy stored in the TLDs as a result of interactions with radiation is removed and measured by a controlled heating process in a calibrated reading system. As the TLD is

) heated, the phosphor releases the stored energy as light. The amount of

) light given off is directly proportional to the radiation dose the TLD t

received. The reading procees ' zeros' the TLD and prepares it for reuse. Du ri ng 1986, tLDs were collected on a monthly and quarterly baais from locations shown in Figures 1 and 2 and described in Table 4. Notice the difference in the number of TLJ locations before and af ter November 20, 1986 (Tables 5 and 6). Fo rty-se ve n new stations were added to the I

TLD monitoring program in 1986, bringing the total number of TLD monitoring stations to sixty-five. Station 2 was deleted because it did not meet the criteria for selection of TLD locations as outlined in the ODCM.

Results Each station consists of both a monthly and qua rte rly TLD. The results of the monthly analyses are shown in Tables 11 through 13. Tables 11 and 12 include stations in use prior to the tech spec change of November 20, 1986, while Table 13 shows the addition of the new stations described above. Figure 4 shows a plot of background and indicator station average monthly exposures for 1986. Note that during January, February, and March, indicator exposures were slightly elevated. This was most likely due to the inoperability of the plant's A0G system. The second set of December values in Figure 4 corresponds to the January reading date in Table 13. Indicator averages for this period were slightly higher than background, however as the plant was operating at only 40% power and due to the fact that this elevation was not seen at all stations near the plant, it is not considered to be plant-related. Spurious exposures of film badges in Table 10 are most likely due to security x-ray in-transit, are not consistent with TLD measurements made at the same time, and are not therefore considered accurate measurements of field exposures.

Environmental Sample Analysis Results Sample Collection Sample types described previously at locations in Figures 1 and 2 are shipped to the radioanalytical la bo rato ry upon collection. Samples collected are analyzed using procedures approved by GPU Nuclear and in keeping with guidelines established in USNRC Regulatory Guide 4.15. For a more detailed description of the media, sampling locations, collection frequencies, and analyses performed, refer to the section on Program Design described earlier (page '22).

Sample Analysis Results Results of sample analyses are summarized in the format of NRC Regulatory Guide 4.8 in tables 15, 16, 17, and 19 on a semiannual, quarterly, and annual basis. Data is summarized in these dif ferent formats in order to comply with Technical Specification requirements both before and after the November 20, 1986 c ha nge . The discussion below includes both the semiannual 1986-2 repo rting period (July through December) and also incorrarates the entire year.

Many naturally-occurring isotopes (e.g., Ra-226, K-40, etc.) were detected in some environmental media, as evidenced in previous semiannual reports. Additionally, some site-specific nuclides from past facility j discharges as documented in previous semiannual reports were detected ,

(Co-60 and Ce-141 in aquatic sediment, and Co-60 in clams). Fission products f rom nuclear weapons testing were also detected in small amounts l in predatory fish (Cs-137). Other media, such s soil and pasture samples also showed long-lived nuclear weapons testing related radionuclides such as co-60 and Cs-137. Tritium was also detectable in surface water and precipitation samples. These conditions we re detected throughout the reporting period and will no doubt be reported in future reports, as they are considered normal for this region of the United States.

l On April 26, 1986 the Chernobyl accident in the Soviet Union contributed approximately 50 million curies of radioactivity products to the atmosphere. Also in this month, Oyster Creek shut down for a maintenance and refueling outage until December 22, 1986. Therefore, any fission products detected between April and December are not likely due to Oyster Creek operations (with the exception of the previously noted instances) but to the Chernobyl accident. On May 5, 1986 significant amounts of I-131 (650 pCi/1) were detected west of the Rocky mountains. Soon after, air samples showed elevated gross beta activity (Figure 5) and detectable amounts of I-131 (Figure 6), Cs-134, Cs-137, Ru-103 (Figure 7), St-89, and Sr-90 at Oyster Creek's bac kg round and indicator stations. Cs-137 and Cs-13 4 we re detected in pasture (Figure 8) and soil samples as late as the fall of 1986. In addition, Cs-137 and I-131 were detected in precipitation samples beginning in May. Cs-137 was again detected in precipitation samples during July and August. All of these nuclides are fission products which were detected at indicator and background stations and are directly attributed to the Chernobyl accident.

In conclusion, with the exception of the historically found facility specific nuclides and those detected as a result of the Chernobyl accident, no nuclides were detected in environmental media as a result of facility operations.

RADIOLOGICAL IMPACT OF OYSTER CREEK OPERATIONS Two principle exposure pathways, inhalation and ingestion, are available to gaseous and liquid effluent isotopes, respectively, in the vicinity of Oyster Creek. Intakes via the inhalation pathway are from gaseous effluents, while the ingestion pathway is via consumption of shellfish from Oyster Creek's discharge canal and Barnegat Say as well as the consumption of garden vegetables. Additionally, a third means of exposure is from direct radiation from Oyster Creek effluents. For purpose of this report the annual total dose due to radioactive effluents for liquids and gases is dete rmined as per OCNGS Technical Specification 4.6.N. Maximum exposure due to gaseous pathways (inhalation, ingestion, and direct radiation) would depend on the predominant wind direction and the location of persons living in a particular sector near the plant.

The hypothetical maximum exposure location due to gaseous effluent is 966 meters to the southeast. The maximum liquid exposure receptor is located approximately .25 miles to the southeast (discharge canal bridge).

Table 20 represents the offsite dose summary for the annual period from January through Dec embe r of 1986. The information provided was calculated using the models and methodology outlined in NRC Regulatory Guide 1.109 and proposed NRC Regulatory Guide 1.111. The analysis herein represents the total annual whole oody, thyroid and maximum organ doses for ooth liquid and gaseous pathdays combined. Also included are the dose limits as given in the Oyster Creek Technical Specifications (4.6.N) and the percent of these technical specification limits.

According to the results in Table 20, Oyster Creek was well within 40 CFR Part 190.10s limits for whole body, thyroid and any other organ for any member of the public as the re sult of exposures to planned discharges of radioactive materials to the general environment.

Lower Limit of detection Exceptionc - 1986 Prior to November 20, 1986 OCNGS Tech. Sp ec s . had no LLD's for REMP. The Prog ram did, however, include self-imposed LLD's in order to ensure its program was stste-of-the-art. Because of the tight controls and requirements Oyster Creek Environmental Controls maintains on its REMP analysis requirements, not only were there no LL6 exceptions for the regulatory-required, post-November 20, 1986 date, there were no LLD exceptions for the entire calendar year.

OYSTER CREEK NUCLEAR GENERATING STATION US EPA CROSS-CHECK PROGRAM 1986 COMPARISON OF EPA AND CONTRACTOR LABORATORY RESULTS A. Teledyne Midwest Results - Mean + two sigma for three determinations. All results are in pCi/L except for air filter samples, which are in pCL/ filter; and food, which is in pCi/kg.

B. EPA Results - Expected la bo rato ry precision Q3 sigma, n=3 control limit). Units are pCi/L for water and milk. Units are total pCi for ait particulate filters. Units f or f ood are pCi/kg.

C. Teledyne Results - Average + one sigma. Units are pCi/L for water, and milk. Units are total pCi ,for air particulate filters. Units for food are pCi/kg.

D. Teledyne Midwest has no explanation for the high SR-90 results in this food sample except that the sample was difficult to analyze. Special attention will be paid to this analysis when analyzing food samples in the future.

E. This sample is a synthetic food which may contain a substance which interferes with the strontium 89 and 90 analysis.

. Only 21 la bo ra to ries participated in the strontium analyses. Of 'the 21 who did participate 42.9% had results beyond the three sigma control limits.

F. Teledyne Midwest has no explanation for the low SR-90 results in this filter sample. Their test result is only 0.7 pCi/ Filter low of the EPA's limit of error. Additional results for SR-90 in air filters in 1986 and in the past have been in good agreement. No further action is planned.

G. The three results were 40, 42, and 37. One of these results was within the two sigma limit: the othe r two we re low, resulting in a low average.

Additional results for Ru-106 in 1986 were in good agreement. No further action is planned.

H. Teledyne Midwest has no explanation for the high CS-137 results in this sample. Additional results for CS-137 in milk in 1986 and in the past were in good agreement. All solid state detectors were recallocated. No further action is planned.

I. It is be lie ved that too much NaCO3 was used in the final precipitation of SrCO3 resulting in a falsely high SR-90 yield. Less NaCO3 will be used in the future precipitation of StC03-J. An investigation is being conducted as of April 20, 1987 and an explanation will be available.
