T TELEDYNE I. INTRODUCTION ISOTOPES This report contains a complete tabulation of data collected during the period January to December 1983, 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 NPPD 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 th2 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 the contractor's laboratory where there exists special f acilities required for measurements of extremely low levels of radioactivity. From 1971 through 1976 the contractor was Teledyne Isotopes, Westwood, New Jersey. NALCO 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, 1983.

(a) There was no sample collected from Station 13 on 06/09; there was no vegetation available.

There were no samples collected in the fourth quarter from station 12.13. or 28. The fluctuatino level of the Missouri River prevented the accumulations of aquatic vegetation. (Total 2 samples collected.)

T TELEDYNE ISOTOPES A and B. AIR PARTICULATE SAMPLES - 3ROSS 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 activity. They were composited for each station quarterly and monitored for gamma activity (See Tables 0-1 and 0-2).

The gross beta activity for each quarter of 1982 and 1983 is sumarized below:

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.

1983 First Quarter 0.024 pCi/Cu. M.

Second Quarter 0.019 pCi/Cu. M.

Third Quarter 0.025 pCi/Cu. M.

Fourth Quarter 0.039 pCi/Cu. M.

The level of gross beta activity has returned to normal environmental levels since the Chinese atmospheric nuclear weapons testing in 1980 increased levels worldwide. There was an increase in gross beta levels in the fourth quarter of 1983 because of the increased activity monitored in the month of December. This increase in both gross beta and gross alpha activity in this month could be related to weather conditions or to an increase in particulate matter on the filters. A trend of the same magnitude was found at other midwestern sites.

The gross alpha activity (Tables B-1 through B-4) continues low and close to the limits of detection with a slight increase in December as noted above. 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 operations of the Cooper Nuclear Station (CNS) of the Nebraska Public Power District.

. T 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 1983 at station 01 through 10 and monitored for radio-iodine.

Tables C-1 through C-4 show the average monthly and quarterly results for each station and the average for all 10 stations. No airborne I-131 was detected; all results were at or below the normal 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.

0. COMPOSITE OF AIR PARTICULATE FI'.TERS - GAMMA (See Tables 0-1 and 0-2)

STATIONS 01 to 10 ,

Weekly Air Particulate filters were composited for eacn station for a quarterly gamma spectral analysis during the-four quarters of 1983.

Beryllium-7, a naturally occurring cosmogenic nuclide, was detected in 40 of 40 samples at a level of 0.117 pCi per cubic mettr which is the same level as in past years. There were two detections of Thorium-228 at station 07 in the first quarter of 1983. This is a natural terrestrial nuclide and the activity was below the normal limit of detection. Potassium-40, also a natural nuclide, was detected in 4 of 40 samples also below the normal limit of detection.

There was one detection of Cs-137, which is a fission product, in the first quarter of 1983 at slightly below the normal limit of detection. This is probably due to fallout from past nuclear weapons testing and occurred in other areas of the United States.

There were no detections of I-l?l 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 it.dication of an effect from the operations of CNS.

ISOTOPES E. EGGS (See Tables El, E2)

STATIONS 42, 51, 67, 76 Egg samples were collected quarterly from four locations and analyzed for elemental calcium, gross beta, Sr-89, Sr-90 and gamma emitters. The gross beta measured 1.8 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 normal 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 three detections of Sr-90 in 15 samples at a level of 0.0019 pCi per gram, wet, which is below the normal 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 samples.

T TELEDYNE ISOTOPES F. FEED AND FORAGE - BEEF PRODUCERS (See Tables F-1 and F-2)

STATIONS 64, 67, 68, 71, 76 Feed and forage samples were collected monthly from beef producers at five 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 gama 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 32 of 73 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 Ra-226 and nine detections of Th-228 in the 76 samples analyzed. These are naturally occurring terrestrial nuclides.

Five detections of Cs-137 occurred at an average activity level of 0.0381 pCi/gm, wet which is below the normal level of detection. There were no detections of Ce-144. These are fission prooucts which occurred in other areas of the United States and are probably residual f allout 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 - T0 MAT 0ES 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 1983. 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 1983 duplicate measurements conducted during previous years.

No Sr-90 was detected in apples; however a small amount of Sr-90 was detected in garden vegetables at slightly above the normal level of detec-tion. This is probably due to residual f allout from past atmospheric nuclear weapons testing.

There were no gamma emitters above the normal levels of detection except K-40 as cited above. It may be concluded that there was no detectable effect on food and garden crops from the operations of CNS.

T TELEDYNE ISOTOPES FEED AND FORAGE (See Tables I-1, I-2 and J-1, J-2)

1. STATIONS 61, 74 (Nearest Milk Producers)

J. STATIONS 42, 73, 75 (Commercial Milk Producers)

Feed and forage was collected from milk producers, nearest the plant, u uarterly from two stations and monthly during peak pasture season. Feed and forage from comercial 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 10 detections of Sr-90 in 14 samples collected from the nearest producers at a level of 0.0173 pCi/gm, wet. There were nine detections of Sr-90 in samples collected from comercial producers at a ievel of 0.0270 pCi/gm, wet. Cs-137 was detected in one sample collected from the nearest pr oducers and one from the commercial producers both slightly below the normal level of detection, Both of these nuclides are fission products and are probably the result of f allout from previous nuclear atmospheric testing. Both nuclides are at a lower level than that of the year 1982.

The naturally occurring nuclide Be-7 was seen in 18 of 31 samples at a level of 1.34 pCi/gm, wet. Potassium-40 was detected in 31 of 31 samples at a level of 7.91 pCi/gm wet, the same as in previous years. There was one detection of thorium-228 which is a terrestrial nuclide.

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 CNS could be ingested by cows from feed and forage and there was no dose impact to the population.

T TELEDYNE ISOTOPES K. FOOD AND FEED CR0PS - CORN AND S0Y BEANS (See Tables K-1 and K-2)

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 emit-ters. Measurements on all of these analyses were similar in activity level and range to those measured in the previous years of 1973 - 1982.

Gross beta activity measured an average of 4.7 i 1.2 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 0.0182 pCi/gm, wet, which is below the normal level of detection. The elemental calcium level was somewhat higher than that of other years at 3.4 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.

T TELEDYNE ISOTOPES L. FISH (See Tables L-1, L-2)

STATIONS 28, 35 Fish samples were collected during the spring and f all and analyzed for gross beta, Sr-89, Sr-90 and gamma emitting isotopes. The gross beta and Strontium-90 Sr-90 activities 'were similar to the levels of previous years.

was detected in nine of ten samples at a level of 0.018 pCi per gram wet, which is below the normal level of detection. There were no detections of Sr-89. All of the gamma emitters were at or below the normal level of detection except K-40, a naturally occurring isotope, which was at a level of 2.83 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.

T TELEDYNE ISOTOPES MILK (See Tables M-1, M-2 and N-1, N-2)

M. STATIONS 42, 73, 75 (COMMERCIAL PRODUCERS)

N. STATIONS 61, 74 (NEAREST PRODUCERS)

Milk samples from commercial producers were collected quarterly from 3 stations aad monitored for I-131, Sr-89, Sr-90, elemental calcium and gamma emitters. Milk samples from nearest producers were collected from two stations monthly and monitored for I-131, Sr-89, Sr-90, elemental calcium and gamma emitters. During peak pasture season weekly samples were collected and monitored for I-131 for the nearest producers. The weekly samples were composited monthly and monitored for Sr-89, Sr-90 elemental calcium and gama emitters.

There were no detections of I-131 in milk from either the twelve samples from the commercial producers or the 60 samples from the nearest producers.

No Sr-89 was detected in any of the milk samples. Strontium-90 was detected in the 12 sr.mples of comercial producers at an average level of 2.5 pC1/

liter. There were detections of Sr-90 in 27 of the 27 samples collected from the nearest producers at an average level of 1.6 pCi/ liter. The elemental calcium levels remained stable as compared with other years. Naturally occurring K 40 remained at the same levels as previous years. There were no other detect ions of gamma emitting nuclides except for one detection of Cs-137 during the second quarter at station 42, a comercial producer. This was at a level of 13.5 pCi per liter, which is above the normal. level of detection. This was probably the result of fallout from previous atmospheric nuclear tests and was observed in other areas of the United States.

There is no statistical difference between the samples collected from nearest producers as compared with comercial producers' samples. Thus we l conclude that the operations of CNS had no effect on milk from commercial

! and thus no dose impact on the population.

T TELEDYNE ISOTOPES P. RIVER WATER (See iable P-1 and P-2) STATIONS 12,13,28 River water was collected mont31y and monitored for gross beta and gross alpha, suspended and dissolved, Sr-39 ar.d 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 (0.25 miles, 120 degrees) in the first quarter at 1.2 pCi/ liter which is slightly above the minimum level of detection. This may have been caused by the flood conditions in the spring. No further detections occurred. The gross alpha and gross beta suspended and dissolved were high as in 1982. The yearly average was in-creased by the high readings in the fourth quarter due to flooding conditions. This is further supported by the increase in gross alpha and gross bata, suspended particules, due to the turbulence. The yearly averages are as follows: 1983 1982 Average pCi/ titer Average per/ liter Gross Alpha 14.2 4.5 l (dissolved) i Gross Alpha 3.5 7.2 l (suspended) l

Grcss Deta 10.7 10.0 (dissolved)

Gross Beta 7.8 16.0 (suspended) This increase in gross beta and gross alpha activity was probably due to naturally occurring nuclides and was not associated with the operations of CNS. These measurements indicate that the river water samples monitored during 1983 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 430 pCi/ liter. 78

T TELEDYNE 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 f all of 1983. 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 detected in four of four samples analyzed at a level of 0.227 pCi/gm, wet, which is similar to the levels of previous yer.rs. Iodine-131 analyses of the thyroid gland conducted by the chemical separation method were below the normal 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 1982. The were no detections of Cesium-137 above the normal level 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. 81

T R. AQUATIC VEGETATION STATION 12, 13, 28 Samples of acquatic vegetation were to be collected twice during the year at Stations 12,13 and 38. In the third quarter two sam;iles were col-lected from Stations 12 and 28. There was no growth at Station 13. This aquatic vegetation was analyzed for gross beta activity, for Strontium 89 and 90 and for gamma-emitting nuclides. The gross beta activity was at a nominal level. There was a small amount of Sr-90, near the minimum level of detection, probably due to fallout from previous nuclear testing. Beryllium-7, a cosmogenic nuclide, was detected in the samples collected. Potassium-40 and thorium-228, terrestrial nuclides, were detected at normal environmental levels. There is no evidence of an effect from the nuclear plant operations on the samples of aquatic vegetation collected. i 84

T TELEDYNE ISOTOPES T. AMBIENT RADIATION - THERM 0 LUMINESCENT 00SIMETERS (TLDs - SEE TABLES T-1 AND T-2) 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 17.2 milliroentgen / quarter (91 days) to 29.9 milli- , Roentgen / quarter. The highest exposure during each of the four quarters i was at Station 01 (0.1 mile, 225 degrees) and averaged 29.9 mR/ quarter. The lowest exposure was at Station 03 (2.5 miles, 338 degrees) and Station 05 (3.5 miles, 102 de5rees) and averaged 17.2 mR/ quarter. The radiation at station 44, which is the control station, was similar to that at the other stations. The average total exposure for the year was 76.9 mR which is considerably below the 125 millirems per quarter specified in 10 CFR 20.105 for an un-restricted area. The relationship between milliRoantge.7 (mR) and millirems (mr) is approximately or,e for the exposure conditions encountered. No plant effect from CNS was indicated. 88
