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 1987 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 1987 the radioactive liquid and gaseous ef fluents associated with OCNGS were a small fraction of the applicable federal regulatory limits and have not had significant or measurable effects on the quality of the environment.

Estimated radiation doses to the public attributable to 1987 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 nornally present in the environment, either naturally or as a result of l non-OCNGS activities such as atmospheric nuclear weapon testing, measurements made in the vicinity of the site were compared to background measurements. l Samples of air, surface water, soil and sediment, shellfish, fish, vegetation, j groundwater, and precipitation were collected. External penetrating radiation dose measurements also were made in the vicinity of OCNGS. Samples were analyzed for radioactivity including tritium (H-3), gross beta and gamma-emitting radionuclides. The re ults of environmental measurements are used to assess the environmental impact of OCNGS operations, to demonstrate i 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 1 i l

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 1987 there were over 3350 samples taken from the aquatic, atmospheric, and terrestrial environments around OCNGS. More than 4275 analyses were performed on these samples.

In addition to natural radioactivity, low levels of fission products such as cesium-137 were detected in various media and were attributed to fallout f rom 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 manganese-54, cobalt-60, and zinc-65, as documented in previous semiannual reports.

, Dose rates measured with TLDs around OCNGS were consistent with historical natural background radiation. Background stations TLD's ranged f rom 3.3 to 5.6 mrem per standard month and indicator station TLD's ranged f rom 2.9 to 7.0 mrem per standard month. l J

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

I l

i

, Operations at OCNGS during 1987 caused radiation doses to the public well below all applicable regulatory limits, and significantly less than doses received from other common sources of radiation. The maximum hypothetical whole body exposure potentially received by an 1

individual from liquid and gaseous effluents was conservatively l calculated to be about 0.17 mrem total. The maximum hypothetical l whole body dose to the surrounding population f rom liquid and airborne effluents was conservatively calculated to be 15.2 person-Rem. This is 1,766 times lower than the doses that the total population in the Oyster Creek area receives from natural background sources.

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

Characterist'.cs of Radiation Atoms whose nuclei contain an excess of snergy are called radioactive atoms. They release this excess energy by expelling electromagnetic or particulate radiation from their' atomic centers to become stable (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 (neutrons). The term "half-lif e' reters 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 directly 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 accelerators and nuclear 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 minuter 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 l

2.2 million decays per minute. The picocurie is one millionth of a microcurie and represents 2.2 decays per minute. The mass of a l radionuclide corresponding to one curie is directly proportional to the 1

3 b

half-life 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 1

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 curie.

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 effects of radiation, the type, energy, and amount of radiation must all be considered.

Total body radiation involves exposure of all organs. Most background exposures are of this form. When radioactive elements enter the body through inhalation or ingestion, their distribution is not uniform. For example, radioiodine selectively concentrates in the thyroid gland, whereas radiocesium collects in muscle and liver tissue and radiostrontium in mineralized bone. The total dose to organs by a given radionuclide is also influenced by the quantity and the duraticn of time that the radionuclide remains in the body. Owing to their rapid radioactive decay as well as their removal f rom 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 f requently 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). Sometimes, it is desirable to express the collective radiation dose to a population. Such a collective dose is I

expressed in person-rem, which is calculated by adding up each individual l

dose (e.g., 1 rem to each of 100 persons = 100 person-tem).

Sources of Radiation Exposure i

Life on earth has evolved amid the constant exposure to natural radiation. In fact, the single major source of radiation to which the J

4

general population is exposed comes from natural sources. Although everyone on the planet is exposed to natural radiation, some people receive more than others. Radiation exposure f rom natural background has three components (i.e., cosmic, terrestrial, and internal) and varies with altitude and geographic location, as well as with living habito.

For example, cosmic radiation originating from deep interstellar space and the sun increases with altitude, since there is less air which acts as a shield. Similarly, terrestrial radiation resulting from the presence of naturally occurring radioauclides in the soil varies and may be significantly higher in some areas of the country than in others.

Even the use of particular building materials for houses, cooking with gas, and home insulation affect exposure to natural radiation.

The presence of radioactivity in the human body results f rom the inhalation and ingestion of air, food, and water containing naturally occurring radionuclides. For example, drinking water contains trace amounts of uranium and radium and milk contains radioactive potassium.

Table 1 summarizes the common sources of radiation and their average annual doses.

The average person in the United States receives about 300 millirems (0.3 rem) per year from natural background radiation sources. This estimate was revised from about 100 to 300 millirems because of the inclusion of radon gas which has always bee present but has not previously figured in the calculations. In some regions of the country, tha amount of natural radiation is significantly higher. Residents of Colorado, for example, receive an additional 60 millirems per year due co the increase in cosmic and terrestrial radiation levels. In fact, for evety :.00 feet above sea level, a person will receive an additional 1 millirem per year from cosmic radiation. In several regions of the world, high concentrations of uranium and radium deposits result in doses of several thousand millirems each year to their residents.

Recently, public attention nas focused on radon, a naturally occurring radioactive gas produced from uranium and radium decay. These elements are widely distributed in trace amounts in the earth's crust. Unusually high concentrations have been found in certain parts of eastern Pennsylvania and northern New Jersey. Radon levels in some homes in these areas are hundreds of times greater than levels found elsewhere in the United States. Howeve r ,

additional surveys are needed to determine the full extent of the problem nationwide. Radon is the largest component of natural background radiation and may be responsible for a substantial number of lung cancer deaths annually. The National Council on Radiation Protection and Measuremento (NCRP) estimates that the average individual in the United States receives an annual dose of about 2,400 millirems to the lung from natural radon gas. This lung dose is considered to be equivalent to a whole body dose of 200 millirems. The NCRP has recommended actions to control indoor radon sources ,

and reduce exposures.

and radioactive strontium concentrates in the bones. 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, including its physical, biological and chemical characteristico. Depending on their rate of radioactive decay and biological elimination f rom the body, some radionuclides stay in the body for very short times while others remain for years.

In addition to natural radiation, we are exposed to radiation from a number of man-made sources. The single largest of these sources comes .

from diagnostic medical x-rays, and nuclear medicine procedures. Some 180 million Americans receive medical x-rays each year. The annual dose a to an individual from such radiation averages about 53 millirems. Much smaller doses come f rom nuclear weapons f allout and consumer products such as televisions, smoke detectors, fertilizers. Production of nuclear power and its associated fuel cycle contributes less than 1 millicem to the annual dose of about 300 millirems for the avecage individual living in the United States.

Fallout commonly refers to the radioactive debris that settles to the surface of the earth following the detonation of nuclear weapons. It is dispersed throughout the environment either by dry deposition or washed down to the earth's surface by rain or snow. There are approximately 200 radionuclides produced in the nuclear weapon detonation process; a number l of these are detected in fallout. The radionuclides found in fallout which produce most of the fallout radiation exposures to humans are iodine-131 (I-131), strontium-89 (Sr-89), cesium-137 ( Cs -137 ) , and strontium-90 (Sr-90). There has been no atmospheric nuclear weapon testing since 1980 and many of the radionuclides have decayed significantly. Consequently, doses to the public from fallout have been decreasing.

As a result of the nuclear accident at Chernobyl, USSR, on April 26, t

1986, fallout waa dispersed throughout the environment and detected in various media such as air, milk, and soil.

i Description of the Oyster Creek Site l

General Information The Oyster Creek Nuclear Generating Station (OCNGS) has generated electricity since December, 1969. The operating license permits station operation 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 f rom Barnegat Bay (Figure 1 - page 9). The 1416-acre site is owned by Jersey Central power & Light Company.. It is situated partly in Lacey "ownship 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 property 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, page 9, relates the site to the more pertinent features of the county, as well as indicating the locations of some of Oyster Creek REMP ststions in Ocean County.

The site location is part of the New Jersey shore area with its relatively flat topography and extensive freshwater and saltwater marshlands. The south branch of Forked River runs across the northern side of the site, and Oyster Creek partly borders the southern side. The region adjacent to the bay is one of the state's most rapidly developing areas. In addition to the resident population, a sizeable seasonal influx of people occurs during the summer. This influx resides almost

. exclusively along the waterfront.

were from the northwest and west-northwest. The normal northwest wind direction is expected as the winter months are dominated by Canadian air masses. From April through June, the wind directions were evenly divided between the northeast / east-northeast and southeast / south-southwest sectors. This defines the second half of the period as the transition months between the winter and summer seasons. Summer months usually have the predominant wind direction from the southwest and south. During the July through September period, the predominant wind direction was from the west, southwest, and south. 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 height of this mesoscale effect (approximately 2:00 to 4:00 in the af ternoon) the wind will parallel the coast - the result created from uneven heating between land and sea coupled with the natural rotation of the earth. The period f rom October throu?h December is usually described as a transition period between the previously described summer patterns and those found in winter (winds from the west-northwest and north). However, the entire second quarter was slightly cooler than usual and represents those conditions found during the winter months. The predominant wind direction during the latter three months was f rom the northwest.

Other characteristics for the second half of 1987 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 fetch have characteristic low clouds, drizzle and fog (stable atmospheres).

A total of 51.19 (water equivalent) inches of precipitation fell during l 1987, which amounts to approximately 8 inches above the annual average.

Near normal precipitation levels were recorded during the first three I months of the reporting period (Figure 2, page 11). 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. For the period of April through June, l April and May were the wettest' months (10.95 and 10.04 inches, j respectively).

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 eff ect of the sea-breeze, common in the month of June and throughout the aummer. Due to this highly stable viather phenomenon, showers build up to the west, move east-northeastward, then become stagnant and eventually decay up to 15 miles inland.

t For the period of July through December, precipitation was below normal (15.12 inches) . The six-month average total from the Atlantic City e

1 National Weather Service historical record is 22.0 inches. During summer i months precipitation is generally characterized by events of short duration but strong intensity (convective showers). With this type of precipitation event, there-will be increased particulate fallout j (washout) from the atmosphere, which has implications for radionuclide {

i deposition. Curing the summer, marine air, which is stable, will generally suppress these convective-type storms and decrease l j precipitation at most coastal locations. The sea-breeze can produce the

! same result. This effect can occur along the coast up to 12 miles inland.

Rainf all events during the six-month period were, for the most part, due to extratropical storms of licht to moderate intensity and long duration, especially during the second quarter.

I EFFLUENTS Limits I

I 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 Protection and Measurements (NCRP) established in 1929, and since 1959, the Federal Radiation Council (FRC)

(incorporated in the U..ited States Environmental Protection Agency in j 1970) for basic radiation protection standards and guidance. These i 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 CFR 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 maintained at levels which are 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 GPU Nuclear.

Technical Specifications 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 operation of gaseous and liquid processing systems, installation and operation of radiation monitoring systems, establishment of an inplant and environmental sampling and analysis program, establishment of a quality assurance program for effluents, procedures covering all aspects of effluents, and calculation of doses to the public.

Table 2 (page 14), outlines the OCNGS effluent technical specifications.

Sources of Radioactive Liquid and Gaseous Effluents \

l

! At the Oyster Creek Nuclear' Generating Station, most of the fission i f

products are retained within the fuel and fuel cladding. However small amounts of radioactive fission. products are able to diffuse or migrate

!, through the fuel cladding and into.the reactor coolant. Trace quantities

of the component and structure surfaces 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 j

purification system of the coolant. The noble gas fission products have ,.

a very low solubility in the coolant and cannot be removed by the demineralizers. Instead they are given off as gas when the coolant is i depressurized and are collected by a system designed for gas collection, 4 '

holdup and emission. This represents the principal source of gaseous effluents.

J l Minute drainage of radioactive liquids f rom valves,_ piping, and/or ,

equipment associated with the coolant system may occur in the Reactor, I 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 O Radwaste Building. Water processed in the radwaste facility that does not meet strict chemical specifications for primary system reuse becomes I the source of liquid effluents.

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 sampled, 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 Of f-Gas ( AOG) System. The holdup pipe allows radionuclides with short half-lives to decay. The Augmented Of f-Gas System is a gaseous processing system which provides hydrogen conversion to water via a catalytic recombiner, removes the water (vapor) f rom the process stream, holds up the process stream to allow further decay of short-lived nuclides, and filters the off-gas using charcoal beds and High Efficiency 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 J.s discharged out the top of the 368-foot stack.

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

Ventilation f rom two buildings ( AOG 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.

Ef fluent Data Radioactive liquids and gaseous releases from OCNGS did not exceed Federal regulatory and Technical Specification limits during 1987.

Radiological releases f rom OCNGS are calculated f rom installed plant ef fluent 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 matarials being released to the environment.

Ten radioactive liquid releases totalling 199,207 gallons were made from the OCNGS in 1987. The total radioactivity released to the environment was 0.00663 curies of fission and activation products, 1.96 curies of Tritium and 0.00284 curies of dissolved and entrained gases. Gaseous releases during 1987 resulted in 3,391 curies of fission and activation gases, 0.085 curies of Iodine-131, 0.020 curies of particulate nuclides with half-lives greater than 8 days, and 7.86 curies of Tritium 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.

RADIOLOGICAL ENVIRONMENTAL MONITORING Program 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 effluents and resultant radiation doses to individuals from principal pathways of exposure. The Oyster Creek Technical Specifications require this program 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 Branch Technical Position on Environmental Monitoring. The important objectives of the REMP aret

, assessing dose impacts to the public from OCNGS operations

, verifying in-plant controls for the containment of radioactive materials

, monitoring to determine buildup of long-lived 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 changes in the radiological status of the environment.

Published inf ormation 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 l

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.

21 J

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, surf 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 levels. The Oyster Creek Technical Specifications Offsite Dose Calculation Manual (ODCM) and recommendations from the scientific staff at Oyster Creek Environmental controls Department specify the sample types to be collected and appropriate analyses.

Sampling locations have been established by considering meteorology, population distribution, hy.drology, 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 least 10 miles from the plant and some as far away as 35 miles. Therefore, background samples are collected at locations which 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 9) and 3 (page 23) show the sampling locations of the Oyster Creek REMP, while a description of each location is outlined in Table 4, page 25.

In addition to specifying the minimum media to be collected and the minimum number of sampling locations, the Technical Specifications also specify the frequency of sample collection, the types of analyses to be l performed, the analytical sensitivity (detection limit), and r eporting levels. Tables 5, page 33, and 6, page 35, provide a summary of the l

sample type, analyses performed, collection frequency, number of sampling locations, and type of analysis. Table A-1 in Appendix A, page 151, presents problems encountered in the sample collection process. Sample analyses which did not meet the required analytical sensitivity are presented in Appendix B, page 155. Reporting level violations are rep'rted o in Appendix C, page 157.

The analytical results are routinely reviewed by environmental scientists at Oyster Creek to assure that sensitivities have been achiaved and that the proper analyses have been performed. Investigationa are conducted when activities fall outside ranges previously deter-!nad based upon historical data or when anomalous values are disco - These ranges are purposely set narrow so that corrective action m '.e 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, j special analysis techniques have been developed. Analytical laboratories l contracted by GPU Nuclear use state-of-the-art laboratory equipment designed to measure the types of radiation emitted (beta and gamma) and meet the required analytical sensitivities. Examples of laboratory j equipment used are germanium detectors with multichannel analyzers for  !

specific gamma emitting radionuclides, liquid scintillation detectors for tritium, and low level beta counters. Computer hardware and software l used in conjunction with the counting equipment perform calculations, data analysis and provide data management.

l The base REMP program analytical laboratory responsibilities were transferred on October 15, 1987 from Teledyne Isotopes, Inc., Westwood, 7

New Jersey to the GPU Nuclear Corporation Environmental Radioactivity Laboratory, Harrisburg, Pennsylvania. The QC REMP program analytical laboratory responsibilities were unaffected and remained with Teledyne Midwest Laboratories, Inc., tb rthbrook, Illinois. l 24 i

Quality Assurance Program The quality assurance program associated with the Radiological Environmental Monitoring Program (REMP) at the OCNGS is governed and l 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 which provides analytical services maintains a quality assurance program in accordance with the requirements of Reg. Guide 4.15. Each laboratoty submits a quality assurance program document with revisions as necessary to the OCNGS Environmental Controls Department for review to ensure that program requirements are satisfied.

The Quality Assurance Program is composed of the following:

REMP QA SAMPLING PROGRAM The number and f requency of REMP quality control samples collected in 1987 are listed on Table 6, page 35. Each 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 other subsample is forwarded to the independent QA contractor laboratory for analysis. ,

i Analytical results f rom each laboratory are evaluated to determine acceptable agreement. If evaluation results in the determination that the results are in non-agreement, then reanalyzing or recounting the samples may result. This system of dividing each sample into three l 1

INTRALABORATORY ANALYSES The primary analytical labotatory performed duplicate analyses on every tenth sample prior to October 15, 1987 and every twentieth sample after October 15, 1987. The number of duplicate analyses performed during 1987 are listed by media on Table 7, page 37. Intralaboratory. analysis of both blank and spiked samples also are performed on a routine basis. The results of all of these analyses are reported on a bimonthly basis as well as results of detector backgrounds and ef ficiencies. Review of data produced by this program and the REMP QA Sampling Program discussed above indicate sacisf actory performance by all laboratories during 1987.

DIRECT RADIATION MONITORING Dose rates from 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, as well as fallout from prior nuclear weapons testing, resulted in a certain 4

amount of penetrating radiation being recorded at all monitoring locations. Indicator TLD'. were placed systematically in sectors of predominant wind direction at the site boundary,1 mile, 2 miles, 5 miles, and 8 miles distant from the site. Backgro'and TLDs were located in locations typically greater than ten miles distance from OCNGS. The results of their exposure are shown in Table 8, page 39.

Sample Collection and Analysis A state-of-the-art thermoluminescent dosimeter is used in Oyster Creek's REMP. Thermoluminescence is a process in which ionizing radiation, upon l

interacting with the sensitive material of the TLD (the phosphor or l

' element') causes some of the energy deposited in the phosphor to be stored in stable ' traps' in the TLD Material. These TLD traps are so l stable that they do not decay appreciably over the course of months or even years. This provides an excellent method of integrating the exposure received over a period of time. The 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 received. The reading process ' zeros' the TLD and prepares it for l

reuse. During 1987, TLDs were collected on a monthly and quarterly basis f rom locations shown in Figures 1, page 9, and 3, page 23, and described in Table 4, page 25. The results of the quarterly TLD's are listed on Table 8, page 39.

Environmental Sample Analysis Results Sample Collection Sample types described previously at locations in Figures 1 (page 9) and 3 (page 23) are shipped to the radioanalytical laboratory upon collection.

Samples 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 21).

Sample Analysis Results Results of sample analyses are summarized for the reporting period in the format of NRC Regulatory Guide 4.8 in Table 10, page 44. A statistical analysis was performed on each analytical result according to sample type, station, and analysis to determine which results, if any, were outside the normal or expected range of environmental activities. These ranges were based upon historical data amassed frF Oyster .eek's Radiological Environmental Monitoring Program surveys for past years. While these "higher-than-expected" results are somewhat elevated, they are in no way considered to be abnormal.

Except where noted, elevated results were not attributed to plant effluents and were, in most cases, naturally occurring isotopes. A discussion of the l

elevated results follows.

l Many naturally-occurring isotopes (e.g. Be-7, K-40, etc.) were detected in i some environmental media, as evidenced in previous Semiannual Reports.

Additionally, some site-specific nuclides f rom past f acility discharges, as documented in previous Semiannual Reports, were detected (Mn-54 and Zn-65 in Aquatic Sediment). Fission products (Cs-137) f rom nuclear weapons testing and the 1986 Chernobyl accident were also detected in small concentrations in one clam and two aquatic sediment samples. Slightly elevated Tritium results were also detected in five precipitation samples and one well water sample.

41

Although these results were found to be higher-than-expected, they remain well within tha ranges considered normal for this region of the United States.

In conclusion, with the exception of the historically found facility-specific nuclides, no concentrations of radioactivity in the environs of Oyster Creek were found to be abnormal during the reporting period.

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. Ir. takes via the inhalation pathday are from gaseous effluents, while the ingestion pathway is via consumption of shellfish from Oyster Creek's discharge canal and Barnegat Bay as well as the consumption of garden vegetables. Additionally, a third means of ecposure is from direct radiation from Oyster Creek effluents. For purpose of this report the maximum hypothetical annual dose due to radioactive effluents foc liquids and gases is determined as per OCNGS Technical Specification 4.6.N. Maximum exposure due to gaseous pathways (inhalation, ingestion, and direct radiation) would depead on the predominant wind direction and the location of persons living in a particular sector near the plant. The hypotbetical maximum exposure location due to gaseous effluent is 966 meters to the southeast. The maximum liquid exposure receptor is located approximately 400 meters to the southeast (discharge canal bridge).

Table 11, page 149, represents the offsite dose summary for the annual period f rom January through December of 1987. 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 maximum hypotnetical annual whole body, thyroid and organ doses for both h liquid and gaseous pathways 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. The maximum hypothetical annual population dose (in person-Rem) was calculated for the annual period.

According to the results in Table 11, page 149, Oyster Creek was well within 40 CFR Part 190.10a limits for whole body, thyroid and any other organ for any J member of the public as the result of exposures to planned discharges of radioactive materials te the general environment. The maximum hypothetical annual population dose for the aforementioned period was 15.2 person-Rem.

This result was based on population data for the year 1985.*

K-40 is in mg/kg.

B. EPA Results - Expected laboratory precision (1 sigma). Units are pCi/l for water, and milk except K !.s in mg/1. Units are total pCi for air particulate filters. Units for food are pCi/kg except K-40 which is mg/kg.

C. Teledyne Results - Average + one sigma. Units are pCi/l for water and milk except K is in mg/1. Units are total pCi for air particulate filters. Units for f ood are pCi/kg except K-40 w'n ich is mg/kg.

D. Teledyne Midwest has no explanation for a low SR-90 result in this sample. All other results for St-90 in water samples analyzed in 1986 and 1987 were within acceptable limits. No other action is planned.

E. No aerosol solution was added to the planchets in the final stages of preparation in order to create a more efficient counting geometry. The technicians in the alpha beta laboratory have been instructed to add the aerosol in accordance with Procedure PRO-031-1.

F. No reason could be ascertained for the high result for Zn-65. Previous results had a normalized deviation from the known of -0.34 (10/10/86) and 0.58 (06/06/86). Therefore this does not appear to be a trend. Further cross-checks will be studied for any problems.

TABLE D-1 (Continued)

OYSTER CREEK NUCLEAR GENERATING STATION US EPA CR03S-CHECK PROGRAM 1987 (JAN - OCT)

COMPARISON OF EPA AND CONTRACTOR LABORATORY RESULTS G. A new rcdiochemical method is being developed for this analysis which should give more accurate results.

H. The p;evious two EPA beta results are 6 percent low, and our in-house beta spikes are low by about the same percentage. Dr. H. Jeter will re-train the analysts in transferring all sample residue into the planchets.

I. The reported high result was due to the small aliquot available for the Sr-90 analysis. Inadvertently a largar aliquot was used for another analysis leaving 40% of the normal volume for St-90. Additionally, the narrow acceptance limits defined by EPA are particularly difficult to meet. For this analysis 63% of the participants were beyond the + 3 sigma limit.

J. The low result is attributed to the application of the reain method rather than the hydroxide method to this analysis. The resin method is inefficient at absorbing protein-bound iodine thus leading to low results. The results obtained by GeLi were higher.

K. Teledyne Midwest Laboratory had dif ficulty with this milk sample for an unknown reason. Previous analyses of milk samples have indicated no difficulties. No other action is planned at this time.

L. The Cs-137 results in EPA Foodr have typically been biased high. We are in the process of performing our annual calibrations. We are using a new Amersham mixed gamma standard rather than the most recently prepared NBS standard which is now several years old. Based on preliminary results the three Cs-137 values would be 52.1, 50.3, and 50.9, which average 51.1.

M. Erroneously high electrode reading of stable iodide in sample (possibly because of interfering species such as divalent sulfur ion) leading to erroneously low chemical yields. After repeating the electrode read.ng, the calculated average I-131 is 49.6 pCi/1. Technicians have been made aware to be suspicious of high electrode readings. When unusually high readings occur samples will be diluted and/or oxidized and remeasured.

N. Results were not reported because samples were lost in processing.

O. Teledyne Midwest Laboratory attempted a new procedure which had yielded acceptable results with spiked samples. Further experimentation is needed with the new procedure.

P. A new Ra-228 analytical procedure is being evaluated as a corrective action to the variability of results with current method. TI No.12115 and TI No.12116 (there was not sufficient sample for a third analysis) were also analyzed by the new procedure with results of 5.9 to 7.0 pCi/1.

The new methed will be used for the next Radium in Water Cross-check samples.

OYSTER CREEK NUCLEAR GENERATING STATION US EPA CROSS-CHECK PROCRAM 1987 (JAN - OCT)

COMPARISON OF EPA AND CONTRACTOR LABORATORY RESULTS Q. Teledyne Midwest Laboratory had unexplained difficulties with this isotope as did 41 other labs of the 100 participating in the study. EPA no longer spikes water with this isotope.

R. The data for the Cr-51 results were reviewed. The detector ef ficiencies appear to be correct. The other five isotopes measured in this sample were within two standard deviations indicating there is no systematte error. Chromium-51 is difficult to measure at this activity level because of the low branching intensity of the gamma ray and being in the high background region of the spectrum since Cr-51 has a low energy ray.

S. An investigation into the causes of this elevated result was ongoing at the time of this writing.

T. Results within specified EPA expected precision of + 3 sigma, N=3 control limit.
