1. INTRODUCTION
  . Ecological Analysts, Inc. (EA) has prepared this semiannual operating report for the Nebraska Public Power District to comply with the Cooper Nuclear Station Environmental Technical Specifications to the NRC
 .  (Section 5.4.1.b).

This report estimates the radiological doses to the area surrounding the Cooper nuclear facility from routine radiation effluent releases. The dose estimates are based upon the atmosphere dispersion as monitored at j the facility. The report provides a summary of the meteorological data collected during the second six months of 1981. This is followed by estimates of'the dispersion characteristics for the period based on the computer model X0QD00. Section 4 reports on the effluent releases and waste disposal at the f acili ty. Dose estimates of gamma radiation due to gaseous releases are presented in Section 5, and individual and population dosages from liquid effluents in Section 6. Four appendixes are included in the report. The appendixes present in

 . tabular form the ' data used in the report tables and figures. Addi tional tables of radiological doses not found in the body of the report also are presented.

2. METEOROLOGICAL DATA

SUMMARY

The meteorological data colle'.ted at the Cooper Nuclear Station 'during the second half of 1981 are summarized in Tables 2-1 and 2-2. These tables were compiled from the monthly data tables presented in Appendix

      .       A. Table 2-1 summarizes the data recovery for each of the meteorological parameters. Table 2-2 summarizes the meteorological data. . The annual statistics in Tables 2-1 and 2-2 are obtained using the data presented in Appendix A of this report-and the Cooper Nuclear Station Semiannual Operating Report, January - June 1981 (NPPD 1981).

2.1 THIRD QUARTER (July - September 1981) Data recovery for the third quarter was greater than 97 percent for each

parameter except 35-ft ambient temperature. The majority of lost data was caused by charts running off the spool and recorder pens not inking.

The 35-ft wind speed experienced abrupt fluctuations in the recorded data in September which resulted in some data loss. The quarterly data recov-ery for the 35-ft ambient temperature was 86.2 percent. This quarter experienced notable losses of data due to abrupt fluctuations in the i recorded ambient temperature data. METEOROLOGICAL

SUMMARY

--The prevailing wind direction for the third quarter was from the south. The next most common direction was north. i This was true at both the 35- and 318-ft heights. The 35-ft wind speed was between 8 and 19 mph 34.0 percent of the time and less than 8 mph 65.7 percent of.the time. The 318-ft wind speed was betweeen 8 and 19 mph 64.3 percent of the time and less than 8 mph 30.3 percent of the time. The' third quarter of 1981 was cooler and slightly wetter than the climatological normal for Auburn, Nebraska, the closest National Weather Service Climatic Station (10 miles west of the plant site). ATMOSPHERIC STABILITY--Differential temperature is measured between both i the 318-35 ft and 318-155 ft levels. Atmospheric stability is derived from the' 318-35 ft- differential temperature data and is reduced to the i seven Pasquill stability categories for use in the joint frequency of wind speed and wind direction analysis. The grand total joint frequency I- of occurrence given in the lower. right hand corner of the joint frequency 4 of occurrence by atmospheric stability tables is used to detennine the

- frequency of occurrence of each stability class. The grand total. joint

. frequency of occurrence for the 318-ft wind speed vs. 318-ft wind direction by stability class is nonnalized to 100 percent for reporting. Based on the joint frequency tables, the atmosphere was unstable 30.6 perecent of the time, neutral 29.4 percent of the time, and stable 40.0 percent of the time for the third quarter of 1981. 2.2 FOURTH QUARTER (October - December 1981) !^ Data recovery for the fourth quarter was greater than 95 percent for each i parameter except 35-ft wind speed. The majority of lost data was caused

. by charts running off the spool and recorder pens not inking. The quarterly data recovery for the 35-ft wind speed was 87.7 percent. This parameter experienced notable losses of data due to abrupt fluctuations 4

in the recorded data. i 2-1

METEOROLOGICAL

SUMMARY

--The prevailing wind direction for the fourth j quarter was from the south-southeast at the 35-ft height and from the south at the 318-ft height. . The next most common wind direction was " i north at the 35-ft height and north-northwest at the 318-ft height. The , 35-ft wind speed was between 8 and 19 mph 48.3 percent of the time and less than 8 mph 48.5 percent of the time. The 318-ft wind speed was , between 8 and 19 mph 51.6 percent of the time and less than 8 mph 24.9

percent of the time. The fourth quarter of 1981 was cooler and drier
                    -than the climatological normal for Auburn, Nebraska.

ATMOSPHERIC STABILITY--Based on the joint frequency tables, the

atmosphere was unstable 17.2 percent of the time, neutral -45.3 percent of
the time, and stable 37.5 percent of the time.

2.3 SEMIANNUAL PERIOD (July - December 1981) Data recovery for the second half of the year was 92 percent or greater for each parameter. Reasons for data loss were given under the quarterly headings. METEOROLOGICAL

SUMMARY

--The prevailing wind direction for the second half

         .           of the year was south-southeast at the 35-ft height and south at the 318-ft height. The next most common direction was north at both the 35-and 318-ft heights. The 35-ft wind speed was between 8 and 19. mph 40.7                                 ,

percent of the time and less than 8 mph 57.6 percent of the time. The ! 318-ft wind speed was between 8'and 19 mph 58.1 percent of the time and

less than 8 mph 27.5 percent of the time. The second half of the year .

was cooler and drier than the climatological nonnal for Auburn, Nebraska. ATMOSPHERIC STABILITY--Based on the joint frequency tables, the ' atmosphere was unstable 23.9 percent of the time, neutral 37.3 percent of 7 the' time, and stable 38.8 percent of the time. ! 2.4' ANNUAL PERIOD (January - December 1981) Data recovery for the year was 93 percent or greater for each parameter. Reasons for data loss were given under the quarterly headings in this report and in the Coo January - June 1981 (perNPPDNuclear 1981). Station Semiannual Operating Report, METEOROLOGICAL

SUMMARY

--The prevailing wind direction for the year was south-southeast at the 35-ft height and south at the 318-ft height. The nnxt most common direction was north at the 35-ft height and north-northwest at the 318-ft height. The 35-ft wind speed was between 8 and 19 mph 44.3 percent of the time and less than 8 mph 51.4 percent of the time. The 318-ft wind speed was between 8 and 19 mph 57.6 percent of the time and less than 8 mph 23.4 percent of the time. The annual period was cooler and much drier than the climatological nonnal for Auburn, . Nabraska. ATMOSPHERIC STABILITY--Based on the joint frequency tables, the - atmosphere was unstable 27.1 percent of the time, neutral 35.5 percent of the time, and stable 37.4 percent of the time. 2-2

(b) The citmatological acrmals were derived fra NOAA Clteatological data for Auburn, Nebraska. (c) Patn days are defined as a cay in which 0.01 inch of rain or rain equivalert af frozen precipitation has fallen, s . . . . .

3. DISPERSION CHARACTERISTICS (X/Q) ISOPLETHS Estimates of the atmospheric dispersion characteristics (X/Q) for the second half of 1981 were made using the NRC supplied model X0QD0Q (U.S.

NRC 1977b). Key input to the model is the joint frequency distribution

 .   (JFT) of atmospheric stability, wind speed, and wind direction. The JFT was determined from the meteorological data and is presented in Appendix B. This section presents the model calculated locations of equal disper-sion for both the 5- and 50-mile radius circles from the Cooper Nuclear Station. The periods covered are July - September, October - December, July - December, and January - December. Separate figures are given for the vent stack and elevated release options.

The data tables from.which the isopleth figures were der;ved are presented in Appendix C and the X0QD0Q computer model is discussed in Appendix D. The X0QD0Q couputer model implements the models and assump-tions of Regulatory Guide 1.111 (U.S. NRC 1976). g 6 3-1

Third Quarter: Fourth Quarter: E8s = 0.22 Mev/ disintegration Ess = 0.27 Mev/ disintegration Eys = 0.27 Mev/ disintegration Eys = 0.44 Mev/ disintegration E6v(Rx) = 0.36 Mev/ disintegration E8v(Rx) = 0.36 Mev/ disintegration Eyv(Rx) = 0.68 Mev/ disintegration Eyv(Rx) = 0.67 Mev/ disintegration E8v(TG) = 0.'33 Mev/ disintegration Esv(TG) = 0.34 Mev/ disintegration Eyv(TG) = 0.63 Mev/ disintegration Eyv(TG) = 0.64 Mev/ disintegration Egv( ARW) = 0.35 Mev/ disintegration Esv(ARW) = 0.39 Mev/ disintegration Eyv(ARW) = 0.66 Mev/ disintegration Eyv(ARW) = 0.70 Mev/ disintegration 4.4 MEASUREMENTS AND APPR0XIMATIONS OF TOTAL RADI0 ACTIVITY The methods used to measure or approximate the total radioactivity in effluents and to detennine radionuclide composition are as follows:

a. Fission and activation gases:

Radioactivity and radionuclide composition is determined by laboratory GeLi detector analysis in correlation with continuous gross radioactivity monitoring by a gaseous channel detector in the release pathway.

b. Iodines:

Charcoal cartridges provide continuous sample collection. These cartridges are analyzed for radioactivity and radionuclide compo-sition in the laboratory by a GeLi detector gamma spectrometer. Continuous radioactivity monitoring of the charcoal cartridge is also provided by a NaI detector in-line with the release pathway.

c. Particulates:

Particulate filters provide continuous sample collection. These l filters are analyzed for radioactivity and radionuclide compo-sition in the laboratory by a GeLi detector gamma spectrometer. l Continuous gross radioactivity monitoring of the particulate filter is provided by a Nal detector in-line with the release

 -           pathway.

5. GAMMA DOSE ISOPLETHS Estimated gamma radiation doses were calculated from the effluent releases presented in Section 4 and the dispersion characteristics presented in Section 3. The NRC supplied conputer model GASPAR was used to calculate locations of equal dosage (isopleths). The isopleth figures are presented for both a 5-mile and a 50-mile radius area centered on the Cooper Nuclear Power Station. The periods covered by the figures are July - September, October - December, July - December, and January -

December. Each figure is for a combined release with the vent stack and elevated release point data used together to estimate the gamna dose at each grid point. The data tables from which the isopleth figures were derived are presented in Appendix C and the GASPAR computer model is discussed in Appendix D. The GASPAR computer model implements the air-released dose models of Regulatory Guide 1.109 (U.S. NRC 1977a). e l l l 5-1

6. RADIOLOGICAL 00SE CALCULATIONS FROM WATER 8ORNE SOURCES In calculating doses to an individual and population caused by the  ;

release of radioactive material via liquid effluent from Cooper Nuclear l Power Station, the LADTAP II (ORNL 1980) computer program was used. The l LADTAP II program implements the radiological impact models of Regulatory Guide 1.109 (U.S. NRC 1977a) for determining the radiation exposure to man from four principal exposure pathways in the aquatic environment-- potable water, aquatic foods, shoreline deposits, and irrigated foods. Doses for both the maximum individual and the general population are calculated as a function of age group and pathway for appropriate body organs. The input data are obtained fran the effluent release report presented in Section 4. t i G 0 j 6-1

APPENDIX A MONTHLY DATA TABLES O

Data from the continuously monitored meteorological parameters collected at the Cooper Nuclear Station were reduced to hourly averages, reviewed for errors, scaled for calibration, and prepared for further analysis by conputer. The hourly average values are presented in the monthly data tables in this section. . Data strip charts were reduced to hourly average values using an automatic digitizer. The . averaging period was centered on the hour; that is, the hourly average for 1400 was obtained from the data trace between 13:30 and 14:30 on the strip chart. The hourly average values were computed from a minimum of 15 minutes of strip chart data trace. precipitation data was reduced manually by totalling the number of tick marks (each tick mark equaling 0.01 inches of precipitation) within an hour centered on the hour as for the other parameters. Each table contains one month of data for one parameter. The tables are captioned with the parameter name, unit of measurement, site name, month, and year. The mean hourly average for each hour of the day is shown in the last row of the main table. The mean hourly average, maximun hourly average, and minimum hourly average for the month are shown beneath the main table. The number of valid observations and the percentage of data recovered also are shown beneath the main table. Daily statistics are shown at the foot of the page. These statistics are the daily maximum, daily minimum, and daily mean hourly averages. Beneath the daily " statistics table, the mean daily maximum and mean daily minimum hourly averages are shown. Totals, rather than means, are reported for precipitation data. Only the hourly average values, number of valid , observations, and the percentage of data recovered are reported for wind direction data. The notation "-M " in the tables indicates a missing data value. The value may be missing because of any of several reasons: equipment fail-ure, power failure, calibrations, recorder inking problems, or sensor icing. A-2 l

I I APPENDIX B JOINT FREQUENCY TABLES , e h

M l l Wind speed, wind direction, and 318-35 ft differential temperature data ) presented in Section A are categorized as shown on Page B-3. Joint frequency of occurrence of each wind speed and wind direction category - for each wind level is computed, and the number of joint occurrences and the percent frequency of occurrence are shown. Joint frequency of occurrence of wind speed versus wind direction is shown across all

  • atmospheric stability categories and for each atmospheric stability category individually. The percent frequency of occurrence is normalized to 100 percent on each table, i.e. , the total in the right hand corner of the table is 100 percent. Row totals and column totals are shown in the right column and bottom row, respectively, of each table. The number of calm hours and the percentage of calm hours are shown in the first wind speed category of each table. The number of valid data pairs collected are shown in the lower right hand corner of each table.
   ~

Several abbreviations are used on the tables: WDC = Wind Direction Category WSC = Wind Speed Category DTC = Differential Temperature Category The numerals 1 and 2 refer to the 35-ft and 318-ft wind levels, respectively. The notation "." indicates missing values. The number of missing data ' pairs is given in the upper left hand corner of each table (see Page B-6 where 37 wind speed - wind direction data pairs are missing for the period 1 July to 30 September 1981). The number of missing pairs due to. . only one parameter being missing is given in the left hand column and top row of each table (see Page B-6 where 2 occurrences of the 1-4 mph category did not have a corresponding wind direction and 1 occurrence of a north (N) wind direction did not have a corresponding windspeed value). The number of missing values are not used in the calculations and are only presented in the interest of completeness. Rows in which no observations occur are not shown in the tables. B-2
