SUMMARY

OYSTER CREEK NUCLEAR GENERATING STATION 1986-1 SEMIANNUAL EFFLUENT RELEASE REPORT I

The Semiannual Effluent Release Report is submitted to the United I States Nuclear Regulatory Commission (NRC) every six months in accordance with the Oyster Creek Nuclear Generating Station (OCNGS) Technical Specifications. It summarizes the radioactive liquid and gaseous effluents released and solid radioactive wastes shipped from the OCNGS.

In addition, it describes the results of environmental measurements undertaken to assess the effects, if any, of such radioactive releases to the environment. Environmental media, including air, aquatic sediment, surf ace water, well water, soil, precipitation, vegetation, shellfish, fish, and crabs, were sampled on a routine basis at semimonthly, monthly and/or quarterly f requencies at 39 locations. The annual magnitude of effort to collect and analyze the environmental samples is in excess of fourmanyearsatacostexceeding$250,000.00. This report concludes that exposures to man from OCNGS radioactive effluents are well below the federal limits contained in Title 10, Part 20 of the Code of Federal Regulations which are considered by the NRC to be acceptable limits to protect the health and welfare of the public.

For clarity, the report is organized into three parts.Section I provides a summary of plant operations for the reporting period.

I I

Section II summarizes the meteorological data and effluents released from the facility for the reporting period. It itemizes gaseous releases of 76,724 curies of fission and activation gases, 2.30 curies of non-particulate halogens, 14.66 curies of tritium, and 0.87 curies of particulate radioactivity. No radioactive liquid releases were made from the facility during the reporting period.Section II also itemizes 101 curies of radioactivity, contained in 146.5 cubic meters of waste, which was shipped of fsite in 15 shipments. These releases are similar to or less than releases of nuclear plants of comparable type, age, and size. -

The report underscores the fact that all effluents released were within the federal regulatory requirements of OCNGS Technical Specifications.

Section III summarizes the results of the Radiological Environmental I Monitor' , Program (REMP). This section concludes that no radioactivity detected in environmental media was attributable to facility operations for the reporting period. Natural radioactivity, weapons testing fallout, and radioactive fallout from the Chernobyl, USSR, event were considered the causes of higher than background readings, where detected. All levels of radioactivity in the environment fall well within the acceptable levels considered by the NRC to safeguard the health and welfare of the general public.

Analysis of Error Associated with the Measurement of Radioactive Materials in Effluents and Solid Wastes Effluents

' All stages of the production of effluent estimates have been assigned an estimated and conservative error potential. Stages include sample collection, radiochemical analys's, and compilation of the effluent estimation process. The use of these error factors assures that facility effluents will not be underestimated.

I Solid Waste The process by which the levels of radioactive materials in solid wastes are estimated is one which requires conservatism throughout.

Representative sample analyses and/or surface contamination surveys are combined with estimates of waste volume to provide the level of radioactive materials in solid wastes. Conservative techniques are used in all phases of this process to assure that the amount of radioactive material in solid wastes is not underestimated.

I Meteorological Data Summary I The Oyster Creek Nuclear Generating Station obtains meteorological data from the site meteorological instrument tower (Figure 1 - Page 23).

The tower is 400 feet tall and located approximately west-northwest of the site at a distance of 2529 feet from the stack. The following instrumentation is located on the tower:

Wind Direction Temperature ,.

380 feet Wind Speed -

(116 meters) 1 Wind Direction i

Temperature Dew Point There are redundant wind speed, wind direction, and temperature sensors at the 33 and 380 foot levels to insure an efficient percentage of data recovery and to comply with regulatory requirements. In addition, a processor calculates temperature dif ferentials ( AT) between I

1

I (150-33) and (380-33)-foot levels. These data are then recorded on charts and stored in an on-site computer and are used to determine atmospheric stability and, in turn, atmospheric dispersion. In addition, the 380-foot level wind speed and wind direction and the (380-33)-foot level temperature differential is monitored and recorded at the Oyster Creek Control Room.

The meteorological tower sensors, chart recorders, and processors are calibrated four times a year, according to the draft NRC Regulatory Guide 1.23, Revision 1. Periodic tower inspections are done to insure maximum data integrity. The average data recovery is 97% for the six month period from January through June of 1986 (Table 9 - Page 62).

Meteorological data are an integral part of the off-site dose assessment program. Occasionally, lower percentages of data recovery, as in the month of March, are the result of sensor, computer hardware, and/or chart recorder malfunctions.

Data Analysis For the first half of the reporting period (January through March),

the predominant wind directions were from the northwest and west-northwest (Figures 2 and 3, pages 57 and 58). In addition, there was a slightly increased component of wind direction from the south-southwest. This can be seen especially at the 380 - foot level and indicates an early transition of weather patterns from the winter to the summer months. The normal northwest wind direction is expected as the winter months are dominated by Canadian air masses. For the second half I of the period (April through June), the predominant wind directions were evenly divided between the northwest / west-northwest and southwest / south-I

I southwest sectors (FiguIes 4 and 5, pages 59 and 60). 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.

Lower than normal precipitation levels were recorded during the first three months of the reporting period (Figure 6, page 61). 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. During the second half of the reporting period, 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.-

I Precipitation during the latter half of this second quarter was primarily due to thundershower activity. Other rainfall activity did not reach the site due to the stabilizing ef f ect of the sea-breeze, common in the month of June and throughout the summer. Due to this highly stable weather phenomenon, showers build up to the west, move east-northeastward, then become stagnant and eventually decay up to 15 miles inland. Only one major storm occurred during the period, that being in mid-April, which dumped 3.48 inches of precipitation on the site over two days. The total precipitation for the period was 15.03 inches. The normal six-month Oyster Creek rainfall is approximately 21 inches. Precipitation events were predominantly the result of extratropical storms more commonly referred to as " northeasters".

These storms are a result of a very active jet stream, the common area of origin of mid-latitude storms.

SUMMARY

Radiological Environmental Monitoring Program Introduction The Radiological Environmental Monitoring Program was conducted during the reporting period in accordance with Technical Specification 4.6.B.3. The Technical Specifications, which refer to the Application for Reactor License, Docket No. 50-219, Amendment No.

65, require five general types of monitoring: (1) atmospheric radiation, (2) fallout, (3) domestic water, (4) surf ace water, and (5) marine life. This monitoring was accomplished by collecting samples of the various environmental media at sample collection stations as outlined in Table 10 and Figures 7 and 8, pages 67 through 72.

Specifically, film badges and thermoluminescent dosineters (TLDs) were analyzed for immersion dose. Particulate filters, air iodine cartridges, precipitation, vegetation, soil, and crops were analyzed for atmospheric radioactivity and fallout. Well water, surf ace water, aquatic sediment, and clams,~ fish, and crabs, as well as the aforementioned media, were analyzed becaUse of their close association with either plant effluents and/or man's consumption. All results from these analyses are reported in Tables 11, 12, 14, 15, and 16, pages 73, 74, and 76 through 191.

During the sampling period, two film badges and TLD's were lost in 1

l the field. The following tables reflect this absence.

I Sampling Techniques Radiological environmental sampling is conducted around the OCNGS as described below:

Environmental Media / Pathway Mode of Sampling I Atmosphere / direct radiation, inhalation Composite of Air-Particulates on' filter I Adsorption of air iodines on charcoal filter

! I Atmosphere / direct radiation Surface Water / direct radiation TLD and Film Badge Grab Sample Well Water / ingestion Grab Sample i

Precipitation / direct radiation Composite i

g lW Vegetation, Crops / ingestion Grab i

Soil / direct radiation Grab Aquatic Sediment / direct radiation Grab Shellfish / ingestion Grab Fish / ingestion Grab I crab / ingestion Grab All samples collected are processed and packed at an offsite lab near the OCNGS, then shipped to the vendor laboratories by courier for analysis. Vendor laboratories prepare samples as instructed by the Oyster Creek Environmental Controls Department. Radiochemical analyses are then performed by vendor laboratory, and results are sent to the Oyster Creek Environmental Controls Department.

An ongoing quality assurance program, as outlined in USNRC Regulatory Guide 4.15, is maintained in order to ensure the quality of radiological sampling and analysis. Specifically, this program includes the splitting of selected samples with a second laboratory, g -e s.

I - - - -

l

I the introduction of blind duplicate samples with the primary laboratory, performance of duplicate analyses on ten percent of all samples, periodic laboratory audits and analysis of the results of participation in the EPA cross check program.

Data Tables 11 through 16, found on pages 73 through 191, represent a summary of all radiological environmental data for the reporting period. Tables 14, 15 and 16 present the data in the manner prescribed in proposed USNRC Regulatory Guide 4.8 and USNRC Branch Technical Position.

Analysis of Data Tables 12 through 16 summarize the results of analyses performed on samples collected as part of Oyster Creek's Radiological Environmental Monitoring Program. Results of analyses were reported on a monthly basis, followed by a statistical analysis of the data. Results were compared to historical ranges for each media, station, and analysis combination. Any anomalous results were noted and appropriate action taken where applicable.

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 discharges as documented in previous semiannual reports were detected (co-60 and Ce-141 in aquatic. sediment, and co-60 in clams). Fission products from nuclear weapons testing were also detected in small a, mounts in predatory fish (Cs-137). Other media, such as 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 were detected throughout the reporting period and will no doubt be reported in future reports, as they are considered normal for this regian. af the United States.

In the months of December through April, 'ILD's near Oyster Creek (stations 1 and Tl) showed slightly increased exposure due to the occasionally inoperable augmented off-gas system. While these exposures are higher than what is normally seen, they are still well within the I

federal limits allowed for Oyster Creek.

-192-I - - - - -

e 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 4

maintenance and refueling outage. Therefore, any fission products detected after April 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 1

detectable amounts of Cs-134, Cs-137, Ru-103, I-131, Sr-89, and St-90 at Oyster Creek's background and indicator stations, and Cs-137 and Cs-134 were detected in pasture samples. In addition, Cs-137 and I-131 were detected in precipitation samples beginning in May. 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 ON MAN 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 Bay as well as the consumption of garden vegetables. Additionally, a third means of exposure is from direct radiation from Oyster Creek effluents. The maximum hypothetical exposure to any individual from liquid pathways would occur to someone standing at the offsite boundary on the shore of the discharge canal (direct exposure) and who consumes shellfish (ingestion). For purposes of this report this hypothetical individual is designated as Receptor fl. Maximum exposure due to gaseous pathways (inhalation, ingestion, and direct radiation) would depend on the I predominant wind direction'and the location of persons living in a sector around the plant. The direction and distance for this individual is given in Tables 17 and 18, pages 196 and 197.

The following tables represent the offsite dose summary for the two quarters of the six-month reporting period. 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 hypothetical liquid and gaseous pathway individual doses (Tables 17, 18, and 19, pages 196, 197, and 198). Also included are the appropriate recommended dose limits as given in 10CFR50, Appendix I, the age group, and the receptor location. The semiannual estimated
