This report contains a complete tabulation of data collected during the '
period January to December 1982, for the operational Radiological Environ-mental Monitoring Program performed for the Cooper Nuclear Station (CNS) of the Nebraska Public Power District (NPPD) by Teledyne Isotopes. Samples were collected in the environs of CNS by fiPPD and analyzed by the Teledyne Isotopes Laboratories in compliance with the Environmental Technical Specifications, Appendix B of the Cooper Nuclear Station Operating License.
Cooper Nuclear Station is located in Nemaha County in the southeast corner of Nebraska on the Missouri River. A portion of the site extends .
into Missouri. The reactor is a 778 megawatt boiling water reactor. Initial criticality was attained on February 21, 1974. The reactor reached 50% power on June 25, 1974 and 100% power on November 20, 1974.
Radiological environmental monitoring began in 1971 before the plant became - operational and has continued to the present. The program monitors radiation levels in air terrestrial and aquatic environments. Samples are collected by NPPD personnel. All are shipped for analysis to a contractor's laboratory where there exists special facilities required for measurements of extremely low levels of radioactivity. From 1971 through 1976 the contractor was Teledyne Isotopes, Westwood, New Jersey. NALC0 Environmental Sciences
, assumed responsibility for the analyses January 1,1977. On November 1, 1978 Hazelton Environmental Sciences Corporation assumed responsibility for the program. Prior to November 1,1978 Hazelton Environmental Sciences operated as NALC0 Environmental Sciences. Teledyne Isotopes again assumed responsibil-ity for the analyses effective January 1,1979 through the present period, December 31, 1982.

A and B. AIR PARTICULATE SAMPLES - GROSS BETA AND GROSS ALPHA .
(See Tables A A-4, B B-4 STATIONS 01 to 10 Air particulates were collected continuously on membrane filters which were changed weekly at Stations 01 through 10. The filters were shipped to Teledyne isotopes and analyzed for gross beta. and gross alpha. They were composited for each station quarterly and monitored for gamma activity (See Tables D-1 and D-2).
The gross beta activity for each quarter of 1981 and 1982 is summarized below:
1981 First Quarter 0.130 pCi/Cu. M.
Second Quarter 0.260 pCi/Cu. M.
Third Quarter 0.053 pCi/Cu. M.
Fourth Quarter 0.033 pCi/Cu. M.
1982 First Quarter 0.035 pCi/Cu. M.
Second Quarter 0.021 pCi/Cu. M. '
. Third-Quarter 0.023 pCi/Cu M.
Fourth Quarter 0.031 pCi/Cu. M.
The level of gross beta activity had returned to normal environmental levels since the Chinese atmospheric nuclear weapons tests of October 16, 1980. The gross alpha activity (Tables B-1 through B-4) continues low ;and close to the limits of detection. This low gross alpha activity is probably due to alpha emitters found in soil and to cosmogenic radiation.' The gross ~
beta particulate levels -in all of the stations are similar to other areas of the United States and indicate no influence from the plant.

M TELEDYNE-ISOTOPES C. AIR RADI0 IODINE - CHARC0AL FILTERS (See Tables C-1 through C-4)
STATIONS 01 to 10 Charcoal filters used in series.with air particulate filters were col-lected weekly during 1982 at ' station 01 through 10 and monitored for radio-iodine.
Tables C-1 through C-4 shew the average monthly and quarterly results for each station and for all 10 stations. No airborne I-131 was detected; all results were at or below the minimum level of detection.
Lack of any detections of I-131 supports the conclusion that no detect-able radionuclides were emitted in air releases from CNS.

D. COMPOSITE OF AIR PARTICULATE FILTERS - GAMMA (See Tables D-1 and 0-2)
STATIONS 01 to 10 Weekly Air Particulate filters were composited for each station for-a quarterly gamma spectral analysis during the four quarters of 1982.
Beryllium-7, a naturally occurring cosmogenic nuclide, was detected in 40 of 40 samples at a level of 0.117 pCi per cubic meter which is the same level as in past years. There was one detection of Thorium-228 at station 07 in the first quarter of 1982. This is a natural terrestrial nuclide and the activity was below the limit of detection. Potassium-40, also a natural nuclide, was detected in 5 of 40 samples also below the limit of detection.
One detection of Co-60 occurred at station 01 during the third quarter.
This sample was analyzed for a second time and the presence of Co-60 was confirmed. This is an activation product and was detected once in a trace amount so that no firm attribution to a plant release can be made.
There were no detections of I-131 in the charcoal filters in series with the air particulate filters. There was no correlation between the level of ,
activity and the stations close to the plant. There was no indication of an effect from the operations of CNS.

STATIONS 42, 51, 67, 76 ,
Egg samples were collected quarterly from four locations and analyzed for
, elemental calciun, gross beta, Sr-89, Sr-90 and gamma emitters. The gross beta measured 1.7 pCi per gram, wet, which was accounted for largely by the naturally occurring, terrestrial isotope K-40. No other gamma emitters were measured above the minimum , level of detection. There were no detections of Sr-89. The level of elemental. calcium in 16 samples was 0.12 mg per gram which is similar to the levels of previous years.
There were two detections of Sr-90 in 16 samples at a -level of 0.0013 pCi per gram, wet, which is below the minimum level of detection and is a residue from past nuclear explosions.
There was no evidence of an- effect from the operation of CNS on egg s amples.

F. FEED AND FORAGE - BEEF PRODUCERS (See Tables F-1 and F-2)
STATIONS 64, 65, 67, 68, 71. 76 ,__
Feed and forage samples were collected monthly from beef producers at six stations and radioassayed for gamma emitters . During peak pasture season (June through September) a monthly composite was made of the weekly samples received and also measured for gmmna activity. The cattle at station 65 were sold and the station discontinued. No sample was collected after May 1982.
Beryllium-7, of cosmic origin, was detected in 37 of 76 samples and the terrestrial nuclide K-40 was detected in 76 of 76 samples at the levels encountered in the past.
There was one detection of radium-226 and two detections of thorium-228 in the 76 samples analyzed. These are naturally occurring terrestrial nuclides.
Ten detections of Cs-137 occurred at an average activity level of 0.0691 pCi/gm, wet. The highest number (five) occurred in the spring of the year.
There were three detections of Ce-144 at a level of 0.550 pCi/gm, wet. These are fission products which occurred in other areas of the United States and are probably residual fallout from previous nuclear weapons testing. There was no indication of a plant effect on feed and forage from the operations of .
CNS.

G. STATIONS 53, 54 - APPLES H. STATIONS 34, 56, 62 - TOMATOES AND GARDEN VEGETABLES Garden crops and apples were radioassayed once during the year at harvest time for gross beta, Sr-89, Sr-90, elemental calcium and gamma emitters.
There was no sample available from station 34; no crop was planted in 1982.
Detectable concentrations of gross beta, elemental calcium and K-40 were monitored in each sample and are the naturally occurring terrestrial nuclides found in food and garden crops. The results monitored during 1982 duplicate measurements conducted during previous years.
No Sr-90 was detected in tomatoes and garden vegetables. There was one detection of Sr-90 in apples at a level of 0.0021 pCi/gm, wet at Station 54, 5.2 miles, 320 degrees. This is below the minimum level of detection and'is probably due to residual fallout from past atmospheric nuclear weapons testing.
There were no gamma emitters above the minimum levels of detection except K-40 as cited above. It may be concluded that there was no detectanle effect on food and garden crops from the operations of CNS.

Feed and forage was collected from milk producers nearest the plant quarterly from two stations and monthly during peak pasture season. Feed and forage from commercial milk producers was collected quarterly from three stations. These samples were monitored for Sr-89, Sr-90, elemental calcium and gamma emitting nuclides.
There were no detections of Sr-89 and elemental calcium remained at levels seen in previous years. There were 22 detections of Sr-90 at a level of 0.046 pCi/gm, wet which is lower than that of the year 1981. Cesium-137 was detected in 4 of 31 samples at a level of 0.055 pCi/gm,. wet. Both of 4 these nuclides are fission products and are probably the result of fallout from previous nuclear atmospheric testing. Both nuclides are at a lower level than that of the year 1981.
The naturally occurring nuclide Be-7 was seen in 18 of 315.amples at a level of 1.58 pC1/gm, wet. Potassium-40 was detected in 31 of 31 samples at a level of 9.08 pCi/gm wet, the same as in previous years. Radium-226 was seen -
in two of 31 samples and Th-228 in four of 31 samples. These are terrestrial nuclides. There 'was no essential difference in the number or level of detec-tion of the naturally occurring nuclides or of the fission fallout products between the feed and forage from the nearest producers or from the commercial producers. Thus it has been established that no nuclides which were related to CriS could be ingested by cows from feed and forage and there was no dose impact to the population.

STATIONS 15, 18, 20, 27, 29, 38, and 41 Food and feed crops were collected once during the year at harvest time
.and monitored for gross beta, Sr-89, Sr-90, elemental calcium and gamma emitters. Measurements on all of these analyses _ were similar in activity level and range-to those measured in the previous years of 1973~- 1981.
Gross beta activity measured an average of- 8.013.4 pCi per gram,' wet.
This was largely due to K-40, the. naturally occurring, terrestrial nuclide.
Strontium-90 was detected in 4 of 8 samples at an average of 0.026 pCi/gm, wet, which is below the minimum level of -detection. -The elemental calcium level was similar to that of other years at 0.47 mg per gram.
From this monitoring data it may be concluded that there was no effect on food and feed crops from the operations of CNS.

-STATIONS 28, 35 Fish samples were collected during the spring and . fall and analyzed for gross beta, Sr-89, Sr-90 and garrana emitting isotopes. The gross beta . and Sr-90 activities were similar to the levels of previous years. Strontium-90 was detected in eight of - ten samples at a -level of 0.014 pCi per gram wet, which is below the minimum level of- detection. There were no detections of Sr-89. All of the gamma emitters were at or below the minimum level of detection except K-40, a naturally = occurring isotope, which was _at a level of 2.3 pCi per gram, wet, approximately '.the same level as in previous years.
There was no significant difference between the fish caught at station 28 downstream from the discharge point and that caught at station 35 upstream from the discharge point. Since no change has occurred in-levels of activity in the isotopes monitored since 1975.it can be concluded that -the operations of CNS have had no effect on fish samples.

STATIONS 11, 47 Groundwater was collected from. two stations quarterly and analyzed for gross beta and gross alpha activity, for tritium and for gamma emitting radionuclides. Station 11 is 0.15 miles from the plant and station 47 is-25.75 miles from, the plant. There was one gross alpha detection at station 11 of 1.8 pCi/ liter in the second quarter of 1982. The gross beta activity averaged 8.3 pCi/ liter which is : statistically the .same as in past years.
There were no detections of gamma emitters above the minimum' level of detec-tion. The tritium level averaged 160 pCi/ liter- for the year which -is the normal environmental level.
~
There was no difference in levels of beta activity or tritium for the station close to the plant as compared with the more distant station. It may be concluded that there is no impact from th5: operations of CNS on the en-vironment as shown by measurements of radionuclides in groundwater.

ISOTOPES P. RIVER WATER (See Table P-1 and P-2)
STATIONS 12,13,28 River water was collected monthly and monitored for gross beta and gross alpha, suspended and dissolved, Sr-89 and Sr-90. A quarterly composite was measured for gamma emitters and tritium.
There were no detections of gamma emitters above the minimum level of detection. No Sr-89 was detected.
There was one detection of Sr-90 at station 13 in the second quarter at 0.76 pCi/ liter which is below the minimum level of detection. This was probably caused by the flood conditions in the spring or it may have been an anomaly since no further detections occurred. The gross alpha and gross beta suspended and dissolved were- higher than in the previous year. The yearly average was increased by the high . dings in the spring due to flooding conditions. This is further supporsed by the increase in gross alpha and gross beta, suspended particules, due to the turbulence.
The yearly averages are as follows:
1982 1981 .
Avcrage pCi/ liter Average per/ liter Gross Alpha 4.5 2.9 (dissolved)
Gross Alpha 7.2 2.7 (suspended)
Gross Beta 10.0 9.5 (dissolved)
Gross Beta 16.0 3.9 (suspended)
This was due to naturally occurring nuclides and is not associated with the operations of CNS. By the last quarter of 1982 readings had returned to normal ~environmei tal levels.
l.
These measurements indicate that the river water samples monitored during 1982 contained no detectable CNS plant radionuclides. Additional verification-of no detectable releases is-the low range of H-3 activity which was from 100.
to 410 pCi/ liter.

ISOTOPES-Q. ANIMALS - RABBITS-(See Tables 0-1 and 0-2)
STATION 28 and 35 Rabbit samples were ' collected from stations 28 and 35 in the fall of 1982. The femur was-analyzed for Sr-89 and Sr-90, the thyroid gland for I-131 and the muscle for gamma emitters. Strontium 90 was.detec.ted in four of four samples analyzed at a level of 0.22 pCi/gm, wet, which is similar to the levels of previous years. Iodine-131 analyses of the thyroid gland conducted by the chemical separation method were below the minimum level of detection.
There were . no gamma emitters detected except for naturally occurring K-40 which was' at the same level as in the previous years from 1977 through 1981.
Cesium-137 was below the lower limit of detection.
The results of the monitoring of rabbit samples indicate that no nuclear plant effects resulting from the operations of CNS were detectable in animal life.

STATIONS 01-10,15,18,22,44,58,59 Ambient radiation was monitored at 16 locations within'a-10 mile radius of CNS and collected quarterly. The quarterly averages of ambient net. gamma radiation ranged from 18.9 6.1 milliroentgen / quarter (91 days) to 22.5 1 6.5 milliroentgen / quarter. The highest exposure during each of the four. quarters was at station 01- (0.1 mile, 225 degrees) and averaged .37.1 i 2.1 mR/ quarter.
The lowest exposure was at station 03 (2.5 miles, 338 degrees) and averaged 17.2 1 0.5 mR/ quarter.
The radiation at station 44, which is the control. station, was similar to that at the other stations'.
4 These exposures were considerably below the 125 millirems. per quarter specified in 10 CFR 20.105 for an unrestricted area. The relationship betwren milliroentgen (mR) and millirems (mr) is approximately one for the exposure i conditions encountered. No plant effect from CNS was indicated.
