SUMMARY

OYSTER CREEK NUCLEAR GENERATING STATION 1987-2 SEMIANNUAL EFFLUENT RELEASE REPORT The Semiannual Effluent Release Report is submitted to the United States Nuclear Regulatory Commission (NRC) every six months in accordance p

with the Oyster Creek Nuclear Generating Station (OCNGS) Technical Specifications. It summarizes the radioactive liquid and gaseous r

ef fluents released and solid radioactive wastes shipped f rom the OCNGS.

In addition, meteorological data are presented in joint frequency tables per atmospheric stability class. This report concludes that exposures to man f rom OCNGS radioactive effluents are well below the federal limits t

contained in Title 10, Part 50 of the Code of Federal Regulations >hich l

are considered by the NRC to be acceptable limits to protect the health '

r and welf are of the public.

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

Section II summarizes the meteorological data and ef fluents released f rom the f acility for the reporting period. It itemizes gaseous releases i of 1985 curies of fission and activation gases, 0.414 curies of non-particulate halogens, 4.60 curies of tritium, and 0.0755 curies of particulate radioactivity. In addition, 0.00661 curies of fission and activation products and 0.581 curies of tritium were released in 3 t'atch liquid releases.Section II also itemizes 34,581 curies of radioactivity, contained in 147.3 cubic meters of waste, which was shipped offsites in 29

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 f ederal regulatory ,

i requirements of OCNGS Technical Specifications.

Section III provides an assessment of Oyster Creek's radiological impact on man. Written and tabular output concludes that exposures to man from facility radioactive effluents for this reporting period are l

Well below the federal regulatory limits specified in 10CFR20, 10CFR50, and the OCNGS Technical Specifications.

Section IV provides a detailed listing of all changes made to the Offsite Dose Calculation Manual and the Process Control Plan dL ing the reporting period. Neither document was changed during the reporting period.

Section V reports any ef fluent monitoring instrument that was inoperative as per Technical Specification 3.15 for the reporting period. Two non-compliances were listed: 1.) Two hydrogen monitors were calibrated using air rather than nitrogen as is required by the Technical Specifications. The monitor vendor confirmed that air versus nitrogen would cause a negligible deviation in the calibration results.

Corrective action was to use nitrogen in the subsequent calibrations.

2.) Operability of the liquid radwaste ef fluent line monitor and the

reactor building service water system ef fluent line monitor could not- be ;

maintained because alarm setpoints were being exceeded due to background i

radiation levels. Corrective action specified in the OC Technical Specifications was implemented. In addition, the NRC was notified in writing of these occurrences in August 1986. ,

Analysis of Error Associated with th, M;rsurement of Radiotetivo Materials in Effluents and Solid Wastes Ef f luent;s All stages of the production of effluent estimates have been assigned an estimated and conservative error potential. Stages include sample collection, radiochemical analysis, and compilation of the effluent estimation process. The use of these error factors assures that

! f acility ef fluents will not be underestimated.

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 surf ace contamination surveys are combined with estimates of waste volume to provide the level of radioactive matarials in solid wastes. Conservative techniques are l

used in all phases of this process to assure that the amount of

) radioactive material in solid wastes is not underestimated.

) Meteorological Data Su mma ry The Oyster Creek Nuclear Generating Station obtains meteorological data f rom the site meteorological instrument tower (Figure 1 - Page 22) .

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:

HEIGHT OF INSTRUMENT INSTRUMENT ABOVE GROUND 33 feet Wind Speed (10 meters)

Wind Direction Temperature Dew Point 150 feet Wind Speed (46 meters)

Wind Direction Temperature 380 feet Wind Speed (116 meters) l Wind Direction l

Temperature Dew Point There are redundant wind speed, wind direction, and tem.perature 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 f erentials (asT) between

j Data Analysis [

r i

During the first quarter of the period (July through Sentember) the  ;

i t j predominant vind direction is from the west, southwest and south (Figures 1

2 and 3, pages 25 and 26). Wiads f rom the west are characteristic of a <

l modified continental palar air mass that follows cold frontal passages.

],

l Winds f rom the southwest are usually associated with maritime tropical air normally present prior to cold frontal passages. Another frequent 7

i

! wind direction is from the south and is the end result of the sea-breeze  !

4 i

f

! phenomenon. At the height of this mesoscale ef f ect (approximately 2:00

! 1

{ to 4:00 in the afternoon) the wind will parallel the coast - the result  ;

created from uneven heating between land and sea coupled with the natural I rotation of the earth. The second quarter (October through December) is usually described as a transition period between the previously described i

summer patterns and those found in winter (winds f rom the west-northwect  !

and north). However, the entire second quarter was slightly cooler than l usual, and, as seen in the wind roses (Figures 4 and b, pages 28 and 29), l TABLE 4 METEOROLOGICAL DATA RECOVERY PERCENTAGE ,

f directions seemed to represent those conditions found during the winter [

mont hs. The predominant wind direction during the second quarter wad i

from the northwest, especially at the 380-foot level.

l 1

other characteristics for the entire six-month period include a small  ;

i maxima of wind direction from the northeast. This is due to the air flow j around large high pressure systems. Periods with this onshore fetch have  !

charact' eristic low clouds, drizzle and fog (stable atmospheres). '

i For the period of July through December, precipitation was below j normal (15.12 inches) . The six-month average total from the Atlantic City National Weather Service historical record is 22.0 inches (Figure 6, page 30). During summer 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 (washout) from the atmosphere, which has implications for radionuctide deposition. During the summer, marine air, which is '

stable, will generally suppress these convective-type storms and decrease precipitation at most coastal locations. The sea-breeze can produce the j same result. This effect can occur along the coast up to 12 miles l inland. Rainf all events during the six-month period were, for the most i

l part, due to extratropical storms of light to moderate intensity and long duration, especially during the second quarter, i

. h RADIOLOGICAL IMPACT ON MAN i

Two principle exposure pathways, inhalation and ingestion, are available 3

to gaseous and liquid effluent isotopes, respectively, in the vicinity of 1

Oyster Creek. Intakes via the inhalation pathway are f rom gaseous effluents,

  • while the ingestion pathway is via consumption of shellfish and fish from i

! Oyster Creek's discharge canal and Barnegat Bay as well as the consumption of l,

garden vegetables. Additionally, a third means of exposure is f rom direct i radiation from Oyster Creek effluents. The maximum hypothetical exposure to i t i J any individual from liquid pathways would occur to someone standing at the

(

of f site boundary on the shore of the discharge canal (direct exposure) and who [

I consumes shellfish and fish (ingestion). For purposes of this report this [

l hypothetical individual is designated as Receptor ll. 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 sector i around the plant. The direction and distance for this individual is given in t

} Tables 10 and 11, pages 67 and 68.  !

quarters of the six-month reporting period. The information provided was  !

1 V. EFFLUENT MONITORING INSTRUMENTATION INOPERASILITY RECORD ,

During the reporting period, July 1, 1987 through December 31, 1987, the following ef fluent monitoring instrumentation non-compliances were recorded:

1. Technical Specification: 4.15.B, Table 4.15.2, notation g ,

Requirement : The CNANNEL CALIBRATION (of the Main Condenser Offgas Treatment System Hydrogen Monitors) shall include the use of at least two standard gas samples, each containing a known volume percent hydrogen in the range of the instrument, balance nitrogen.

Non-Compliance: Instrument / breathing air was used during caliorations rather than the specified nitrogen.

Corrective Action: Subsequent calibrations have used nitrogen gas as per the Technical ,

Specification. The monitor vendor was contacted and appraised and their conclusion was that the use of air versus nitrogen would cause a slight / negligible deviation in the calibration of the monitor.

2. Technical Specification: 3.15.A.4 Requirement: When less than the minimum number of a

radioactive liquid effluent monitoring instrumentation channels are OPERABLE, take the ACTION shown in Table 3.15.1.

-7 3 -

f

Make every reasonable effort to restore the instrument to OPERABLE status within 30 days and, if unsuccessful, explain in the next Semiannual Radioactive Effluent Release Report why the inoperability was not corrected in a timely manner.

Non-Compliance: Failure to maintain operability of:

1.) Liquid Radwaste Effluent Line Monitor 2.) Reactor Building Service Water System Effluent Line Monitor due to background radiation le'rels exceeding alarm setpoints. These non-compliances cover the period of November 20, 1986 through December 31, 1987.

Corrective Action: The corrective actions specified in Table 3.15.1 of the OC Technical Specifications were implemented.

Daily overboard discharge samples have been taken and analyzed since October 1986. In addition, the licensee had notified the NRC by letter in August 1986 of the inoperable status of the 7

service water system discharge monitor i

and the long term plans to addtess inoperability.
