. l L' INTRODUCTION '
This report contains a complete tabulation of data collected during the I period January through December 1993, for~ the operational Radiological j Environmental Monitoring Program performed for the Cooper Nuclear !
Station (CNS) of the Nebraska Public Power District (NPPD) by. Teledyne Isotopes.
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: l Missouri. The reactor is a 778 megawatt boiling water reactor. Initial
- criticality.was attained on February 21, 1974. The reactor reached 50% i
- 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. Most samples are collected by NPPD personnel. All are shipped.for analysis to a 1
contractor's laboratory where there exists special: facilities required. for measurements of extremely low levels of radioactivity. From 1971. through 1
- 1976 the contractor was Teledyne Isotopes, Westwood, New Jersey. NALCO Environmental Sciences assumed responsibility for the analyses effective January 1,1977.
4 On November 1,1978 Hazelton Environmental Sciences- Corporation (HESC) assumed responsibility for the program. Prior to -November 1,1978 i Hazelton Environmental Sciences' operated as NALCO Environmental
- Sciences. Teledyne Isotopes again assumed responsibility for the analyses effective January 1,1979 through December 31,1993.

SUMMARY
Presented in this report are summaries and discussions'of the data generated for the Radiological Environmental Monitoring Program (REMP) for the Cooper Nuclear Station (CNS) of the Nebraska Public Power District -
(NPPD) for 1993.
Part V, Table 3 presents the yearly summary of the program with the total j number of samples of each type analyzed, the yearly average for all samples, the number of detections per total number of samples, the station with the highest average, the average of the control station, and the inclusive dates of the analyses.
Part VI is a discussion of each type of sample analyzed and its impact, if any, on the environment. Included also is a graph of the isotopes of interest since 1977 and the statistical results for each quarter of the year. This is followed by a complete tabulation of the data by sample type and station number. .
The 1993 radiological environmental measurements for CNS indicates that there has been no residual fallout resulting from the explosion and fire at the Chernobyl Reactor in the Soviet Union .which occurred on April 26.
j 1986. It may be concluded from all measurements taken that the operations of CNS had no detectable impact on the environment in the vicinity of CNS.

! III. SAMPLING AND ANALYSES PROGRAM. STATIONS AND MAPS I~ The 1993 sampling and analysis program is described in Table 1.
l Teledyne Isotopes has a comprehensive quality assurance / quality control
!- program designed to assure the reliability of data obtained. The results for
, 1993 of the Intercomparison Program conducted by the EPA Environmental
! Monitoring Systems Laboratory in Las Vegas, Nevada, are contained in Appendix B.
Sampling locations are summarized in Table 2. The type or status of l i
each location and its distance and direction from the reactor elevated re- '
lease point are specified. A map of locations follows (Figure 1). Complete descriptions of current and earlier sampling locations are given in Appendix G.
The annual land use census for 1993 is described in Appendix A.
. There were no milk animals found within three miles of CNS in 1993.
] Gardens were found in 11 sectors within 3 miles of CNS in 1992. Only 4 Sectors contained gardens during 1993 due to the flooding of the Missouri River.
All of the required samples were analyzed in 1993 except for the ,

l IV. DISCUSSION A. Program Obtectives and Data Interoretation ,
The objective of the monitoring program is to detect and assess the im-pact of possible releases to the environs of radionuclides from the operations -
of the Cooper Nuclear Station. This objective requires measurements of low levels of radioactivity equal to or lower than pre-determined limits of detection. In addition the source of the environmental radiation must be es-tablished. Sources of environmental radiation include:
(1) Natural background radiation from cosmic rays (Be-7).
(2) Terrestrial, primordial radionuclides from the environment (K-40, Ra-226. Th-228).
l (3) Fallout from atmospheric nuclear tests such as the September 1977 detonation by the Peoples' Republic of China and the atmospheric weapons test of October 16,1980 (fission products and fusion products).
(4) Releases from nuclear power plants such as CNS (fission products and neutron activation products).
(5) Fallout from the Chernobyl Nuclear Reactor Accident.
l Radiation levels measured in the vicinity of an operating power station are compared with preoperational measurements at the same locations to distinguish power plant effects from other sources. Also, results of the '
monitoring program are related to events known to cause elevated levels of radiation in the environment, e.g., atmospheric nuclear detonations or ab-normal plant releases. .
11 Atmosnheric Nuclear Tests Three atmospheric nuclear detonations in the People's Republic of China influenced program results significantly in late 1976 and in 1977. Two of these detonations occurred in late 1976 (September 26 and November 17) and one in late 1977 (September 17). As a consequence of these tests ele-vated activities of gross beta in air particulate filters and I-131 in milk were
! observed throughout most of the United States.
No atmospheric nuclear tests have been conducted since 1977, thus no short-lived fission products were detected in air particulate samples. Also no I-131 was detected from radiogases from any sources. j On April 26,1986 the fire and explosion of Chernobyl Reactor No. 4 in ;
the Soviet Union resulted in the release of fission products to the atmo-sphere and worldwide fallout. Following the explosion, elevated levels of gross beta activities in air particulates and I-131 in charcoal filters and milk -
samples were measured. Additionally, in 1986, Cs-137 and the short-lived isotopes I-131. Ru-106, and Cs-134 were detected in broadleaf vegetation. '
Similar results occurred in other areas of the United States and the entire l Northern Hemisphere.

V. RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM TABLES
, Presented in Table 3 are the radiological environmental monitoring l program summaries (REMPS) generated from the reports of analyses per-formed during 1993 for the NPPD sampling and analyses program. The REMPS tables conform to the requirements of Table 1 in Regulatory Guide 4.8 (Reference 6).
The average activity level for all samples collected for the year for each sample type are summarized in this table. The mean, range and fraction of detections to total samples assayed are presented. The station location and station number with the highest annual mean is also tabulated. If a control station is specified the comparable results of the control are listed.
From the REMPS table it is possible to determine the total number of each type of sample analyzed and the average activity of all samples from all stations of each nuclide. If there were no positive detections the maximum of the lowest levels of detection is listed. The station having the highest level of activity is specified. From this data it is possible to determine any ,
high levels of activity and the source. The dose impact on the population can '
thus be evaluated. ,

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 on membrane filters at ten locations (01-10). The filters were changed weekly and analyzed for gross beta and gross alpha activities. -Quarterly composites are analyzed for gamma emitting iso-topes.
The average gross beta activity of all stations for each quarter of 1992 and 1993 is summarized below:
1992 First Quarter - 0.024 pC1/Cu. M.
Second Quarter 0.019' pC1/Cu. M.
Third Quarter. 0.020 pCi/Cu. M.
Fourth Quarter 0.027 pC1/Cu. M.
Average 1992 0.023 pCi/Cu. M.
I 1993 First Quarter 0.030 . pCi/Cu. M.
Second Quarter 0.015 pC1/Cu. M.-
, Third Quarter 0.020 pC1/Cu. M.
Fourth Quarter 0.029 pCi/Cu. M.
Average 1993 0.024 pC1/Cu. M.
The level of beta activity was at normal environmental levels in 1993 showing the natural seasonal variations. There was a slight increase in the level of gross beta activity during the first quarter; there was a slight decrease from the second quarter of 1992:-the third quarter was the same:
the fourth quarter was slightly higher as shown in Table A-4. The increase j and decline in activity often occurs and is attributed to natural phenomena. 1 The gross alpha activity continued low and close to the limits of detec- 1 tion. Gross alpha activity is probably due to the alpha emitters found in soil and particulates drawn into the filters.
No effect attributable to the Cooper Nuclear Station was observed-in the results of monitoring air particulates.

STATIONS 01 to 10 ,
l Figure A1, B1 shows the gross beta, gross alpha and Ce-144 activity in the environs of CNS. The results for 1986 through 1993 are on the second page of Figure A-1. B-1. The gross beta activity in 1993 was similar to previ-ous years in which there were no nuclear atmospheric weapons tests or nu-clear accidents. The gross alpha activity remained low and near the normal detection level. Cesium-144 was below the level of detection.
l Figure A-2 shows the gross beta activity in air samples through April l
1989 at Jefferson City Missouri as reported by the Environmental Radiation l Monitoring System (ERAMS) of the US Environmental Protection Agency.
No more recent data was available. This data was taken from Environmental Radiation Data distributed by the Eastern Environmental Radiation Facility.
Montgomery. Alabama. The measurements by ERAMS were made after a waiting period which may explain the somewhat lower results because of decay of the isotopes having a shorter half-life. Measurements of Cc-144 were no longer reported because the activity has approached the limit of de-tection by the analytical techniques now used.

Figure C-1 plots the results of I-131 as monitored in charcoal filters and summarized monthly in 1993 compared with previous years. Results for 1993 were below the normal limits of detection indicating no atmospheric effect from the operations of CNS.

D. COMPOSITES OF AIR PARTICULATE FILTERS - GAMMA (See Tables D-1 and D-21 ,
STATIONS 01 TO 10 Air Particulate Filters, which were collected weekly, were composited for each station for a quarterly clamma spectral analysis during the four quar-ters of 1993.
Beryllium-7, a_ naturally occurring cosmogenic nuclide, was detected in 39 of 39 samples at a level of 0.12 pC1 per cubic meter which is similar to the levels of past years. Potassium-40, also a naturally occurring nuclide, was detected in four of 39 samples at a level near the normal level of detection.
Figure D-1 graphs the gross-beta, gross alpha and Ce-144 activity as measured on air particulate filters collected weekly at 'CNS. (This is .the same as Figure A-1 B-1). The plot illustrates that there were no detections of Ce-144 above the normal level of detection as measured by the quarterly gamma scan of samples from CNS. ,
Figure D-2 shows that measurements of Ce-144 are no longer reported' by the Environmental Measurements Laboratory of the US Department of l
Energy because the artificial nuclides such as Ce-144, have reached the lim-
- its of detection by the analytical techniques now used.

- Fish samples were collected during the summer and fall at the above stations and analyzed for gross beta. Sr-89, Sr-90, and gamma emitting l isotopes. An attempt was made to collect a middle-top feeding fish (carp) and a bottom feeding fish (catfish). Due to the near-flood conditions of the i Missouri River in the summer, only carp were available in sufficient numbers for a valid sample. Both types of fish were collected during the fall sampling event.
The gross beta and Sr-90 activities were similar to the levels of previous years. Strontium-90 was detected in four of eight samples at a level of l 0.0066 pCi/ gram, wet. which is below the normal level of detection. There )
were no detections of Sr-89. Naturally occurring K-40 was detected in all samples at an average level of 3.29 pCi/gm wet.
There were no detections of Cs-137 during .1993. ,
l Plotted in Figure E-1 are the radionuclides gross beta, K-40, Sr-90 and Cs-137 monitored in fish samples which show no appreciable change from 1977 through 1993. The plot of the nuclides shows that most of the gross beta activity is due to the terrestrial nuclide K-40.

Milk samples from the nearest producer Station 99, 10.25 miles, 189 .
degrees from the elevated release point of CNS were collected once every 15 days in peak pasture season and once every 31 days the rest of the year.
The monthly samples collected January through May and October through December were analyzed for 1-131 by chemical separation, for elemental calcium and strontium 89 and 90. In addition they were analyzed for gamma emitting isotopes on a high resolution gamma spectrometer. The samples colle'cted every 15 days during peak pasture season were analyzed upon re-ceipt for 1-131 and gamma emitting isotopes. A monthly composite was prepared and analyzed as described above.
There were no detections of I-131 in the twenty-three samples analyzed by chemical separation. There were no detections of Sr-89 in the samples ,
analyzed. Strontium-90 was detected at an average level of 2.0 pCi/ liter, which is a normal environmental level. Elemental calcium was found at an average level of 1.6 mg/ liter. Potassium-40, a naturally occurring isotope, was detected at an average level of 1370 pC1/ liter.
Cesium-137 was not detected in any of the samples analyzed. There was l no indication of an effect on the milk of the producer nearest the plant from

Milk samples were collected quarterly from other producers, Station 42, 12.9 miles from the plant and Station 100 which'is 11.5 miles from the plant. The samples were analyzed for I-131 by chemical separation. for elemental calcium, for Sr-89 and 90 and for gamma emitting isotopes.
There were no detections of I-131 in the eight samples monitored.
There were no detections of Sr-89. Strontium-90 was found at an average level of 1.6 pC1/ liter. There were 1.8 mg of calcium per liter of milk.
Potassium-40 was detected at an average level of 1410. pCi/ liter. The strontium-90. K-40 and elemental calcium were at normal environmental levels and were similar to the results obtained from analyses of milk from the nearest producer. There were no detections of Cs-137 in the samples collected. It can be concluded that the operations of CNS had no effect on milk samples and thus no dose impact on the population.
The levels of radioactivities of the nuclides K-40, I-131 and Cs-137 are plotted on Figure G-1. Potassium-40 was at normal environmental levels as in previous years. There were no detections of I-131 or Cs-137. Figure G-2 shows that Sr-90 and elemental calcium are at a level comparable to previous
, years and there were no detections of Sr-89. These graphs indicate that there was no appreciable difference between the levels of activity of the nearest producer and the commercial producers. This indicated no effect on milk samples from the operations of CNS.

H. GROUNDWATER (See Tables H-1 and H-2)
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. Stadon 11 is 0.15 miles from the plant and station 47 is 25.75 miles from the plant.
The gross beta activity averaged 9.5 pC1/ liter which is statisucally similar to past years. 'Ihere was one detection of alpha at Station 47 with an activity level of 3.0 pCi/ liter. which frequently occurs from natural ground sources.
There were no detections of gamma emitters above the normal level of detection. The tritium level averaged 140 pCi/ liter for the year.which is the normal environmental level.
j There was no difference in levels of beta activity or tritium for the l
station close to the plant as compared with the more distant station. It may i be concluded that there was no impact from the operations of CNS on the environment as shown by measurements of radionuclides in groundwater.
Shown in Figure H-1 are the gross alpha, gross beta and tritium levels in
!- groundwater. The levels of these activities have remained essentially
- unchanged.

I. RIVER WATER (See Table I-1 and I-21 l, STATIONS 12. 28
. River water was collected monthly and monitored for gross beta and gross alpha, suspended and dissolved. Sr-89 and Sr-90 plus gamma emitting isotopes. A quarterly composite was measured for tritium.
- There were three detections of potassium-40 with an average of (66,0 pC1/1) above the normal level of detection. There were no detections of Sr-89 and Sr-90.
i The average gross alpha and gross beta readings were similar to previous years as indicated in the summary of 1992 and 1993 averages below:
l l
1992 1993 Average pCi/ liter Average pCi/ liter L Gross Alpha 4.4. 4.0 l (dissolved) l l Gross Alpha 3.1 3.9 l

l Figure I-1, which follows, is a plot of the gross alpha and gross beta of l suspended and dissolved particles. The results for 1986 through 1993.are l on the second page. The levels of activity continued to rise and fall within l statistical limits depending on water levels and turbulence and were probably
! due to naturally occurring isotopes. No fission or reactor activation products l were detected. Figure I-2 illustrates the level of activity for tritium. Sr-89 l and Sr-90.

STATIONS 01-10. 20. 44. 56. 58. 59 66. 67. 71. 79-91. 94 Ambient radiation was monitored at 32 locations within a 10 mile radius of CNS and collected quarterly. The quarterly averages for all stations of ambient net gamma radiation ranged from 11.8 milllRoentgen/ quarter to 32.0 milliroentgen / quarter. The highest exposure during each of the four quarters was at Station 01 (0.1 mile, 225 degrees) and averaged 23.2 mR/ quarter. The lowest exposure was at Station 03 (2.5 miles,338 degrees) averaging 14.0 milliroentgen / quarter.
The radiation at station 44, (10.5 miles, 270 degrees) which is the control station, was an average of 19.4 mR/ quarter his was similar to other stations and to the average of all stations which was 17.0 mR/ quarter.
The average total exposure for the year was 67.2 mR which' is considerably below the 125 millirems per. quarter specified in 10 CFR 20.105 for an unrestricted area. The relationship between milliroentgen (mR) and millirems (mr) is approximately one for the exposure conditions encountered. . No plant effect from CNS was indicated. ,
The gamma exposures monitored ~ by thermoluminescent dosimeters from 1977 through 1993 are plotted on Figure J-1. The data from year to ,
year is in good agreement and indicates no adverse changes in radiation exposure to the population near CNS.

K. VEGETATION. BROADLEAF (See Tables K-1 and K-2) o STATIONS 35.44.96 Broadleaf vegetation was collected each month during the growing season, May through October. Three samples were collected each month from each station plus a quality control sample except for July when no 1 samples were collected from Station- 35. The samples were tested for I-131 by chemical separation and for gamma emitting isotope.s by high resolution spectrometry.
The naturally occurring isotopes Be-7, K-40 Ra-226 and Th-228 were detected in the samples at normal environmental levels. No I-131. was detected in any of the 57 samples. Cesium-137 was detected in four samples at an average of 0.018 pC1/gm, wet. Cesium-137 is detected in other areas of the United States and is attributed to fallout from previous atomic weapons f testing. The amounts detected are not considered to be significant. j See Figure K-1 for the levels of activities in food samples as rep-resented in broadleaf vegetation in 1993.

L SHORELINE SEDIMENT STATION 28 Shoreline _ sediment. samples were collected in the spring and fall from ~
Station 28,1.8 miles,150 degrees downstream of the release point' of CNS. i They were analyzed for gamma emitters by means of a high resolution gamma j l
l spectrometer. In the-samples collected the naturally occurring isotopes Be- l 7, K-40, Ra-226 and Th-228 were detected at normal environmental levels. l Cesium-137, a fission product, was detected at an average level of 0.052 l pCi/gm, dry.
For the samples collected in the fourth quarter the naturally occurring isotopes K-40, Ra-226 and Th-228 were detected at about the same level as in the second quarter. Beryllium-7 was detected at a level of 0.26 pC1/gm dry in the second quarter and 0.63 in the fourth quarter. Manganese-54, an l activation product - was detected at a level of 0.015 pCi/gm dry in the spring.
Cerium-141 was detected in the fourth quarter sample at a level of 0.0422 pC1/gm dry. All other nuclides were below the detection limit for both the spring and fall.
Presented in Figure L-1 are the plots of the radionuclides K-40,1-131, Cs-134 and Cs-137 in shoreline sediment since .1985. No detections of I-131 nor Cs-134 were seen and K-40 was at a normal environmental level. . l' The Cs-137 was at a low level which is found in many areas and media. Since -
sediment tends to trap and retain any elements in the water pathway, it acts as a good indicator of the effects on the water pathway of any reactor -
effluents.

! IAND USE CENSUS
[ July 31, 1993 ,
0-3 Miles Cooper Nuclear Station (CNS) Radiological Effluent Technical Specifications (RETS) require .an annual land use census. This census identifies the location of the nearest garden that is greater than 500 square feet-in area and yields edible leafy vegetables, the location of the nearest milk animal, and the location of the nearest resident in each of the 16 meteorological sectors within 3 miles of l CNS. i In accordance with the CNS RETS, a land use census'was l performed on August 10, 1993 to determine the state and use of property at the close of July 1993. A census was not possible until this time because'of the disastrous flooding that plagued the area around the plant during the month of July and late June..
Many gardens and residences were destroyed and at the time of this census it is unclear which homes will be repaired or replaced and which ones will be abandoned. In questioning property owners about gardens, some indicated that, because of the heavy rain and large increases in raccoon and deer population in higher ground, gardens (even in higher ground) were abandoned-or mowed over even before
, the heavy flooding.
Sectors A-K were under several feet of water and few houses will be inhabited yet this year. Only 6 sectors had inhabitants within 3 miles, and only 4 sectors had gardens.
i No milk animals were found within 3 miles of CNS in 1993
! and there was no evidence of potable water use from the river.

, (a) EPA Results-Expected laboratory precision (1 sigma). Units are pC1/ liter for water and milk except K is in mg/ liter. Units are total pCi for air particulate filters.
(b) Teledyne Results - Average i one sigma. Units are pCl/ liter for water and milk except K is in mg/ liter. Units are total pCi for air particulate filters.

(c) Normalized deviation from the known.
The EPA switched from Am-241 to Th-230 alpha spike. We calibrated with Th-230. l (d) using sodium nitrate to generate a self absorption curve. The EPA water, however l has minerals which have greater self-absorption than the sodium nitrate matrix. The l EPA has agreed to send us a gallon of their water which we can use to prepare a self- l l
absorption curve with Th-230. 1 (e) By oversight, we did not use the special self-absorption curve which we had l' previously derived using EPA water and Cs-137 standard. We will use the EPA curve !
in the future. We may also re-derive this curve using a water sample which the EPA l
has agreed to send us.
(0 The counting data and backgrounds were verified. Possibly some efilciencies used I were erroneously high causing low values. A less likely cause is an error in dilution.
New Ra-226 standards will be prepared. Closer monitoring of out of control efficiencies will be done and extra care in preparation of the sample will be l maintained.
(g) The calculations were checked and found to be correct, The results of six gamma emitting isotopes were reported to the EPA. The results of four were within 1 normalized deviauon; a fifth. within 2 normalized deviations. Only the Zn-65 average was outside the control limits. There is no obvious reason why one isotope should be outside the control limits, while five other isotopes were within control limits.

APPENDIX C STATISTICAL NOTES
- 1. Each activity is reported in one of two forms: .
X 1 s or
<L, where l
x = value of measurement; i
s = counting error at the 95%
confidence level (2 sigma error);
L = detection limit based on 4.66 sigma error l for counter background
- 2. All activities are corrected to collection time except for gross alpha and gross beta.
- 3. Computation of means:
(a) In any statis'tical table, the values are entered as x s or <L where x = sample mean = Ix; n
n = number of data points averaged; T = average of the 2 sigma counting errors = Is n
(b) For gross beta and gross alpha results in air particulates, averaging includes values which are less than the lower limits of detection.
l The detection limit is used as the sample activity in these cases.
(c) In all cases,. if all values in an averaging group are below detec-tion limits, the highest i.f the detection limits is reported as a "less than" value without an associated tolerance. If some values are above detection limits and some are below, then: ,
I 1
C-1
(1) The mean of the positive results is reported and the number of positives is listed in parentheses.
(d) Means are reported on a quarterly basis except for air particulate and airborne iodine data which are reported monthly. For air particulate and charcoal filters, data for samples collected on the 1st, 2nd, and 3rd day of a month are assigned to the previous month.
(e) In rounding off, numbers followed by a 5 or higher digit are rounded upwards.
