SECTION I. INTRODUCTION 7

I. INTRODUCTION This report contains a complete tabulation of data collected during the period January through December 2009, for the operational Radiological Environmental Monitoring Program performed for the Cooper Nuclear Station (CNS) of the Nebraska Public Power District (NPPD) by Teledyne Brown Engineering - Environmental Services.

Cooper Nuclear Station is located in Nemaha County in the southeast comer of Nebraska on the Missouri River. A portion of the site extends into Missouri. The reactor is an 830-megawatt (net electrical) boiling water reactor. Initial criticality was attained on February 21, 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. All samples are collected by NPPD personnel.

All samples are shipped for analysis to a contractor's laboratory where there exists special facilities required for measurements of extremely low levels of radioactivity. Teledyne Brown Engineering - Environmental Services has the responsibility f6r the analyses for Cooper Nuclear Station.

The United States Nuclear Regulatory Commission (USNRC) regulations (10CFR50.34a) require that nuclear power plants be designed, constructed, and operated to keep levels of radioactive material in effluents to unrestricted areas as low as is reasonably achievable (ALARA). Inplant monitoring is used to ensure that release limits are not exceeded. As a precaution against unexpected or undefined environmental processes, which might allow undue accumulation of radioactivity in the environment, a program for monitoring the plant environs is included in NPPD's CNS Offsite Dose Assessment Manual (ODAM).

A. Atmospheric 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 elevated activities of gross beta in air particulate filters and 1-131 in milk were observed throughout most of the United States. No atmospheric nuclear tests have been conducted since 1980, thus no short-lived fission products were detected in air particulate samples.

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 atmosphere and worldwide fallout.

Following the explosion, elevated levels of gross beta activities in air particulates and Iodine-131 in charcoal filters and milk samples were measured. Additionally, in 1986, Cesium-137 and the short-lived radionuclides Iodine-131, Ruthenium-106, and Cesium-134 were detected in broadleaf vegetation. Similar results occurred in other areas of the United States and the entire Northern Hemisphere.

B. Propram Objectives and Data Interpretation The objective of the monitoring program is to detect and assess the impact 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 established. SQurces of environmental radiation include:

(1) Natural background radiation from cosmic rays (Beryllium-7).

(2) Terrestrial, primordial radionuclides from the environment (potassium-40, radium-226, thorium-228).

(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.

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 abnormal plant releases.

SUMMARY

AND DISCUSSION OF 2009 ANALYTICAL RESULTS Data from the radiological analyses of environmental media collected during 2009 are tabulated and discussed below. The procedures and specifications followed in the laboratory for these analyses are as required in the Teledyne Brown Engineering Quality Assurance manual and are explained in the Teledyne Brown Engineering Analytical Procedures. A synopsis of analytical procedures used for the environmental samples is provided in Appendix C. In addition to internal quality control measures performed by Teledyne Brown Engineering, the laboratory also participates in an Interlaboratory Comparison Program. Participation in this program ensures that independent checks on the precision and accuracy of the measurements of radioactive material in environmental samples are performed. The results of the Interlaboratory Comparison are provided in Appendix B.

Radiological analyses of environmental media characteristically approach and frequently fall below the detection limits of state-of-the-art measurement methods. The "less than" values in the data tables were calculated from each specific analysis and are dependent on sample size, detector efficiency, length of counting time, chemical yield (when appropriate) and the radioactive decay factor from time of counting to time of collection. Teledyne Brown Engineering's analytical methods meet or are below the Lower Limit of Detection (LLD) requirements given in Table 2 of the USNRC Branch Technical Position, Radiological Monitoring Acceptable Program (November 1979, Revision 1). Appendix C contains a discussion of the LLD formulas.

The following is a discussion and summary of the results of the environmental measurements taken during the 2009 reporting period (Graphs now only reflect the last ten years data):

18

A. Airborne Particulates Gross beta activity was observed in 515 of the 518 indicator samples collected during 2009. The average concentration was 0.022 pCi/m 3 with a range of 0.008 to 0.096 pCi/m 3. The results of the gross beta activities are presented in Section VII-1 and Trending Graph 1. The gross beta activities for 2009 were comparable to levels measured in the previous several years. Prior to that period the gross beta activities were higher due to atmospheric nuclear weapons testing performed in other countries. The preoperational period of 1971 through 1974 averaged 0.098 pCi/m 3 gross beta.

Air particulate filters were collected weekly and composited by locations on a quarterly basis. They were analyzed by gamma ray spectroscopy. The results are presented in Section VII-2. Beryllium-7, which is produced continuously in the upper atmosphere by cosmic radiation, was measured in 29 of 40 composite3 samples. The indicator locations had an average concentration of 0.166 pCi/m with a range of 0.098 to 0.250 pCi/m 3. During the preoperational period, beryllium-7 was measured at comparable levels. Thorium-228 was measured in one sample at a concentration of 0.018 pCi/m 3 . All other gamma emitters were below the detection limits.

C. Fish Aquatic biota can be sensitive indicators of radionuclide accumulation in the environment because of their ability to concentrate certain chemical elements, which have radioisotopes. The results are presented in Table VII-3 and Trending Graph 3. Eight samples of fish were collected during the summer and fall of 2009. A middle-top feeding fish (carp) and a bottom feeding fish (catfish) were collected in July and September. These samples were analyzed by gamma ray spectroscopy. Naturally occurring potassium-40 was detected in all samples. The average concentration at the upstream control location was 3083 pCi/kg (wet weight) with a range of 2790 to 3550 pCi/kg (wet weight). The average concentration for the four indicator samples was 3210 pCi/kg (wet weight) with a range of 2890 to 3860 pCi/kg (wet weight). The preoperational period of 1971 through 1974 averaged 2400 pCi/kg potassium-40. All other gamma emitters were below their detection levels.

D. Milk - NearestProducer Milk samples are collected once every 15 days in peak pasture season and once every 31 days the rest of the year from Station 99. The results are presented in Table VII-4 and Trending Graph 4. Sixteen samples were analyzed by gamma ray spectroscopy and for low-level iodine-131 by radiochemical separation.

Naturally occurring potassium-40 was measured in all samples with an average concentration of 1254 pCi/liter and a range of 1070 to 1480 pCi/liter.

Thorium-228 was measured in one sample at a concentration of 13.6 pCi/liter.

All other gamma emitters were below their detection levels.

E. Milk - Other Producers Four milk samples were collected from one location of other producers during 2009 and results are presented in Table VII-5 and Trending Graph 5. Station 103 was sampled quarterly in 2009. Naturally occurring potassium-40 was detected in all four samples analyzed with an average concentration of 1268 pCi/liter and a range of 1170 to 1430 pCi/liter. All other gamma emitters were below their detection levels. The operation of the Cooper Nuclear Station has no discernable impact on milk samples.

H. ThermoluminescentDosimeters Thermoluminescent dosimeters (TLDs) determine environmental radiation doses and the results are presented in Table VII-8 and Trending Graph 8. Ambient radiation was monitored at 32 locations within an 11 mile radius of the Cooper Nuclear Station and collected quarterly. The quarterly average for the indicator locations was 22.7 millirem/quarter and a range from 19.4 to 30.0 millirem/quarter. The control station 44, which is located 10.3 miles, 270 degrees, had an average of 24.2 millirem/quarter and a range from 22.8 to 25.5 millirem/quarter. The highest station was Station 86 with an average of 24.8 millirem/quarter and a range from 22.9 to 30.0 millirem/quarter. The preoperational period of 1971 through 1974 averaged 7.0 millirem/quarter. The data from year to year is in good agreement and indicates no adverse changes in radiation exposure to the population near the Cooper Nuclear Station.

I. Food- BroadleafVegetation Eight broadleaf vegetation samples were collected in June, July and August from three locations during 2009, due to broadleaf vegetation samples being unavailable in May and September. The samples were analyzed by gamma ray spectroscopy and for low-level iodine-131 by radiochemical separation. The results are presented in Table VII-9 and Trending Graph 9. Beryllium-7, which is produced continuously in the upper atmosphere by cosmic radiation was measured in all eight samples analyzed. The average concentration for the two indicator locations was 1426 pCi/kg wet and a range of 588 to 2730 pCi/kg wet.

The average concentration for the control location was 766 pCi/kg wet with a range of 624 to 1020 pCi/kg wet. Naturally occurring potassium-40 was measured in all eight samples analyzed. The average concentration for the two indicator locations was 5394 pCi/kg wet and a range of 2580 to 7090 pCi/kg. The average concentration for the control location was 5253 pCi/kg wet with a range of 4030 to 6740 pCi/kg wet. Naturally occurring thorium-228 was measured in four of eight samples. The average concentration for the two indicator locations was 61.2 pCi/kg wet and a range of 31.5 to 90.9 pCi/kg. The average concentration for the control location was 17.8 pCi/kg wet with a range of 12.2 to 23.3 pCi/kg wet. All other gamma emitters were below their detection levels.

The operation of the Cooper Nuclear Station has no discernable impact on broadleaf vegetation samples.

J. Shoreline Sediment Sediment samples were collected during May and October from Stations 28 and 35 and were analyzed by gamma spectrometry. The results are presented in Table VII-10 and Trending Graph 10. A number of naturally occurring radionuclides were detected in these samples. Naturally occurring potassium-40 was observed in all four samples. The average concentration for the one supplemental station was 12650 pCi/kg (dry weight) and a range of 11400 to 13900 pCi/kg (dry weight). The average concentration for the one indicator station was 16950 pCi/kg (dry weight) and a range of 16700 to 17200 pCi/kg (dry weight).

Radium-226 was observed in one sample from the supplemental station and one sample from the indicator station. The concentration for the supplemental station was 1260 pCi/kg (dry weight). The concentration for the indicator station was 2080 pCi/kg (dry weight). Thorium-228 was observed in all samples. The concentration for the supplemental station was 869 pCi/kg (dry weight) a range of 807 to 930 pCi/kg (dry weight). The concentration for the indicator station was 1071 pCi/kg (dry weight) a range of 961 to 1180 pCi/kg (dry weight). All other gamma emitters were below their detection limits.

This graph has the ODAM LLD trend line, showing the MDC results as below the ODAM required LLDs. The upward trend indicates shortened detector count time in order to maximize the number of samples counted each day, and is not an indication that the trend will continue to increase above the LLD limit.

SECTION V. CONCLUSIONS 31

V. CONCLUSIONS The results of the 2009 Radiological Environmental Monitoring Program (REMP) for the Cooper Nuclear Station (CNS) of the Nebraska Public Power District (NPPD) have been presented. The report contains data tables, summaries, and discussions of the data and trending graphs.

Naturally occurring radioactivity and residual traces of fallout were observed in sample media in the expected ranges. They have been discussed individually in the text.

Observed radioactivity was at very low concentrations.

The results of the analyses have been presented. Based on the evidence of the Radiological Environmental Monitoring Program, the Nebraska Public Power District, Cooper Nuclear Station has had no discernable radiological impact on the environment and is operating within regulatory limits.

APPENDIX A 2009 LAND USE CENSUS A-1

2009 LAND USE CENSUS Conducted July 8, 2009 0-3 miles Cooper Nuclear Station (CNS) Offsite Dose Assessment Manual (ODAM) requires 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 leafy green vegetables, the nearest milk animal, and the location of the nearest resident in each of the 16 meteorological sectors within 3 miles of CNS.

A land use census was performed on July 8, 2009, in accordance with the CNS ODAM. The nearest residence was found in sector Q, 0.9 miles from CNS, and the nearest garden was found in sector L, 1.3 miles from CNS.

No milk animals were found within 3 miles of CNS and there was no evidence of potable water use from the Missouri River within three miles of CNS.

SUMMARY

OF INTERLABORATORY COMPARISONS The Teledyne Brown En2ineering ICP report is presented in this section B-1

INTERLABORA TORY COMPARISION PROGRAM The purpose of the Interlaboratory Comparison Program (ICP) is to confirm the accuracy of results produced by Teledyne Brown Engineering. Samples of various matrices (i.e. soil, water, vegetation, air filters, and milk) are spiked with known amounts of radioactivity by commercial vendors of this service and by departments within the government. TBE participates in three programs. Two are commercial, Analytics Inc.

and Environmental Resource Associates (ERA) and one is a government sponsored program, the Department of Energy's (DOE) Mixed Analyte Performance Evaluation Program (MAPEP). The DOE's Idaho National Engineering Laboratory administers the MAPEP. All three programs are blind performance evaluation studies in which samples with known activities are sent to TBE for analysis. Once analyzed, TBE submits the results to the respective agency for evaluation. The results of these evaluations are published in TBE's quarterly and annual QA reports.

The 2009 Interlaboratory Comparison Program includes all contractually required matrices and analyses we supply to customers.

The US Environmental Protection Agency (EPA) discontinued their Interlaboratory Comparison Program in December 1998. However, on May 1, 2001, accreditation was granted to Environmental Resource Associates' (ERA) RadCheM Proficiency Testing Program to complete the process of replacing the USEPA-LV Nuclear Radiation Assessment Division program.

The Department of Energy's Environmental Measurement Laboratory (EML) program terminated performance assessments at the end of the March 2004 test session.

The MAPEP sample distribution was expanded to include water, soil, vegetation and air particulate testing material previously provided by DOE/EML. In 2009, the samples were received in March and September with required reporting dates of May and October, respectively.

The National Institute of Standards and Technology (NIST) is the approval authority for laboratory providers participating in Intercomparison Study Programs; however, at this time, there are no approved laboratories for environmental and/or radiochemical isotope analyses.

Trending graphs are provided in this section for the Analytics and ERA Programs.

GROSS BETA ANALYSIS OF AIR PARTICULATE SAMPLES Air Particulates After a delay of five or more days, allowing for the radon-222 and radon-220 (thoron) daughter products to decay, the filters are counted in a gas-flow proportional counter.

Calculations of the results, the two sigma error and the lower limit of detection (LLD):

RESULT (pCi/m3) = ((S/T) - (B/t))/(2.22 V E)

TWO SIGMA ERROR (pCi/m3) = 2((S/T ) + (B/t 2 ))l/ 2 /(2.22 V E)

LLD (pCi/m3) = 4.66(B 1/2)/(2.22 V Et) where:

S Gross counts of sample including blank B Counts of blank E Counting efficiency T Number of minutes sample was counted t Number of minutes blank was counted V Sample aliquot size (cubic meters)

DETERMINATION OF GROSS BETA ACTIVITY IN WATER SAMPLES Introduction The procedures described in this section are used to measure the overall radioactivity of water samples without identifying the radioactive species present. No chemical separation techniques are involved.

One liter of the sample is evaporated on a hot plate. A smaller volume may be used if the sample has a significant salt content as measured gravimetrically. If requested by the customer, the sample is filtered through No. 54 filter paper before evaporation, removing particles greater than 30 microns in size.

After evaporating to a small volume in a beaker, the sample is rinsed into a 2-inch diameter stainless steel planchette, which is stamped with a concentric ring pattern to distribute residue evenly. Final evaporation to dryness takes place under heat lamps.

Residue mass is determined by weighing the planchette before and after mounting the sample. The planchette is counted for beta activity on an automatic proportional counter. Results are calculated using empirical self-absorption curves which allow for the change in effective counting efficiency caused by the residue mass.

Detection Capability Detection capability depends upon the sample volume actually represented on the planchette, the background and the efficiency of the counting instrument, and upon self-absorption of beta particles by the mounted sample. Because the radioactive species are not identified, no decay corrections are made and the reported activity refers to the counting time.

The minimum detectable level (MDL) for water samples is nominally 1.6 picoCuries per liter for gross beta at the 4.66 sigma level (1.0 pCi/L at the 2.83 sigma level), assuming that 1 liter of sample is used and that /2 gram of sample residue is mounted on the planchette. These figures are based upon a counting time of 50 minutes and upon representative values of counting efficiency and background of 0.2 and 1.2 cpm, respectively The MDL becomes significantly lower as the mount weight decreases because of reduced self-absorption. At a zero mount weight, the 4.66 sigma MDL for gross beta is 0.9 picoCuries per liter. These values reflect a beta counting efficiency of 0.38.

ANALYSIS OF SAMPLES FOR TRITIUM (Liquid Scintillation)

Water Ten milliliters of water are mixed with 10 ml of a liquid scintillation "cocktail" and then the mixture is counted in an automatic liquid scintillator.

Calculation of the results, the two sigma error and the lower limit detection (LLD) in pCi/L:

RESULT (N-B)/(2.22 V E)

TWO SIGMA ERROR 2((N + B)/At)/2/ (2.22 V E)

I/2 LLD 4.66(B/At) /(2.22 V E )

where: N = the gross cpm of the sample B = the background of the detector in cpm 2.22 = conversion factor changing dpm to pCi V = volume of the sample in ml E = efficiency of the detector At = counting time for the sample C-5

ANALYSIS OF SAMPLES FOR IODINE-131 Milk or Water Two or more liters of sample are first equilibrated with stable iodide carrier. A batch treatment with anion exchange resin is used to remove iodine from the sample. The iodine is then stripped from the resin with sodium hypochlorite solution, is reduced with hydroxylamine hydrochloride and is extracted into carbon tetrachloride as free iodine. It is then back-extracted as iodide into sodium bisulfite solution and is precipitated as palladium iodide. The precipitate is weighed for chemical yield and is mounted on a nylon planchette for low-level beta counting.

Calculations of results, two sigma error and the lower limit of detection (LLD) in pCi/L:

At = counting time for sample (min)

B = background rate of counter (cpm) 2.22 = dpm/pCi V = volume or weight of sample analyzed Y = chemical yield of the mount or sample counted DF - decay factor from the collection to the counting date E = efficiency of the counter for 1-131, corrected for self absorption effects by the formula E = Es(exp-0.006 1M)/(exp-0.006 1Ms)

Es = efficiency of the counter determined from an 1-131 standard mount MS = mass of Pd 12 on the standard mount, mg M = mass of PdI2 on the sample mount, mg C-6

GAMMA SPECTROMETRY OF SAMPLES Milk or Water A 1.0 liter Marinelli beaker is filled with a representative aliquot of the sample.

The sample is then counted for approximately 1000 minutes with a shielded high purity germanium (HPGe) detector coupled to a VAX-based data acquisition system, which performs pulse height analysis.

Dried Solids other than Soils and Sediments A large quantity of the sample is dried at a low temperature, less than 100'C. As much as possible (up to the total sample) is loaded into a tared 1-liter Marinelli and weighed. The sample is then counted for approximately 1000 minutes with a shielded HPGe detector coupled to a VAX-based data acquisition system, which performs pulse height analysis.

Fish As much as possible (up to the total sample) of the edible portion of the sample is loaded into a tared Marinelli and weighed. The sample is then counted for approximately 1000 minutes with a shielded HPGe detector coupled to a VAX-based data acquisition system, which performs pulse height analysis.

Soils and Sediments Soils and sediments are dried at a low temperature, less than 100°C. The soil or sediment is loaded fully into a tared, standard 300 cc container and weighed. The sample is then counted for approximately six hours with a shielded HPGe detector coupled to a VAX-based data acquisition system, which performs pulse height and analysis.

Charcoal Cartridges (Air Iodine)

Charcoal cartridges are counted up to five at a time, with one positioned on the face of an HPGe detector and up to four on the side of the HPGe detector. Each HPGe detector is calibrated for both positions. The detection limit for 1-131 of each charcoal cartridge can be determined (assuming no positive 1-131) uniquely from the volume of air, which passed through it. In the event l-131 is observed in the initial counting of a set, each charcoal cartridge is then counted separately, positioned on the face of the detector.

C-7

Air Particulates The thirteen airborne particulate filters for a quarterly composite for each field station are aligned one in front of another and then counted for at least six hours with a shielded HPGe detector coupled to a VAX-based data acquisition system which performs pulse height analysis.

A VAX software program defines peaks by certain changes in the slope of the spectrum. The program also compares the energy of each peak with a library of peaks for isotope identification and then performs the radioactivity calculation using the appropriate fractional gamma ray abundance, half-life, detector efficiency, and net counts in the peak region.

The calculation of results, two sigma error and the lower limit of detection (LLD) in pCi/volume or pCi/mass:

RESULT = (S-B)/(2.22 t E V F DF) 1/2 TWO SIGMA ERROR = 2(S+B) /(2.22 t E V F DF)

LLD = 4.66(B) /(2.22 t E V F DF) where: S = Area, in counts, of sample peak and background (region of spectrum of interest)

B = Background area, in counts, under sample peak, determined by a linear interpolation of the representative backgrounds on either side of the peak t = length of time in minutes the sample was counted 2.22 = dpm/pCi E = detector efficiency for energy of interest and geometry of sample V = sample aliquot size (liters, cubic meters, kilograms, or grams)

F = fractional gamma abundance (specific for each emitted gamma)

DF = decay factor from the mid-collection date to the counting date C-8

ADDENDUM TO GAMMA SPECTROMETRY PROCEDURE Ba-140 (half-life =~-1 2.8d) decays to LA-140 (half-life -40 hrs) and the daughter radionuclide, La-140 approaches - 90 % of the Ba-140 activity within- 6 days. The La-140 photon energy at 1596 keV is used to quantify the Ba-140 activity due to its high photon emission probability yield (96%) producing a higher count rate when present and therefore, a smaller associated counting error.

Zr-95 (half-life = -65d) decays to Nb-95. (half-life = -35d). The photon energy of Nb-95 (-765 keV) is used to quantify Zr-95 because of the high photon emission probability yield (~-100%) yielding a higher count rate and an associated lower counting error. The daughter radionuclide, Nb-95 approaches the Zr-95 activity after a time period of -65 days, an estimated time interval occurring between sample exposure, collection and shipping, and analysis.

ENVIRONMENTAL DOSIMETRY Environmental Dosimetry services are provided-by Global Dosimetry Solutions, Inc. (GDS). GDS uses a thermoluminescent dosimeter (TLD) manufactured by Panasonic, Inc. Panasonic identifies it as an UD-814A1 TLD. The TLD has four elements, numbered 1-4. Elements and their filtration are composed of:

ELEMENT MATERIAL FILTRATION 1 nLi 2nB4 0 7 -Cu Thin plastic 2 CaSO 4-Tm Lead 3 CaSO4-Tm Lead 4 CaSO 4-Tm Lead This material has a high light output, negligible thermally induced signal loss (fading) and negligible self-dosing. The energy response curve (as will as other features) satisfies NRC Regulatory Guide 4.13. Transit doses are accounted for by use of separate TLDs.

Prior to being sent to Cooper Nuclear Station, the GDS badges are exposed to Cs-137, to known a dose and read in the Panasonic UD-710 reader, with reference badges to establish an element response level for each badge. Badges are then re-annealed for assignment and distribution to Cooper Nuclear Station.

Following the field exposure the badges are returned to GDS for processing in a Panasonic UD-710 reader. Each element is heated and the measured light emission is recorded. The transit controls are read in the same manner. Total exposure for each badge is the average of Elements 2, 3, and 4.

Transit Controls are calculated using the following equation:

(E31 + E4 1 + E32 + E42) _ (E3t.mn + E4r,_)

TRANSDOSE= "4 2 C-10

LOWER LIMIT of DETECTION FORMULAS The LLD formulas in Appendix C are consistent with the LLD discussion in the ODAM. The term Sb in the ODAM equals 41B/t by Poisson statistics, where B = blank counts and t = blank counting intervals. The decay factor term e-2At in the ODAM is the same as the DF terms in Appendix C, but does not appear in certain analyses such as gross beta because decay does not apply. In the tritium analysis, decay is not considered because of the relatively long half-life.

Efficiencies and volumes are consistent between the two documents. Chemical yields appear in Appendix C where applicable but do not apply to other analyses such as tritium and gross beta.

GASEOUS EFFLUENT DOSE CALCULATIONS Doses to the maximum individual and 0 to 50 mile population resulting from the release of radioactive material in gaseous effluents from the Cooper Nuclear Station were calculated using the GASPAR computer code. Four sites were selected for individual dose calculations: the site boundary, the nearest residence, the nearest garden and the nearest cow. GASPAR implements the radiological dose models of Regulatory Guide 1.109 for determining the radiation exposure to man from four principal atmospheric exposure pathways: plume, ground, inhalation, and ingestion. Doses to the maximum individual and the population are calculated as a function of age group and pathway for significant body organs.

Tables 1 through 7 present maximum individual doses. Population doses are given in Tables 8 through 14.

Assumptions and data used for input to the GASPAR code are described in a separate section of this appendix (see page F-52).

DOSE CALCULATION MODELS To evaluate the radiological consequences of the routine release of liquid and gaseous effluents from the Cooper Nuclear Station, two computer codes were used: LADTAP II for liquid doses and GASPAR for gaseous doses. Both of these computer codes implement the dose calculational methodologies of U.S. NRC Regulatory Guide 1.109, Revision 1.

Source terms for each quarter are combined with station-specific demographic data and either hydrological dilution factors, for liquid dose calculations, or atmospheric diffusion estimates, for gaseous dose calculations.

For liquid dose calculations, the hydrological dilution factors used for input to LADTAP II, as well as other input parameters, are listed in Table 15. Other inputs not specifically listed in this table are taken from Regulatory Guide 1.109, Revision 1. Semiannual doses are obtained by summing the contributions from the appropriate quarters.

For gaseous dose calculations, atmospheric diffusion estimates are obtained from the reduction and processing of onsite meteorological data. Source terms for the semiannual period are obtained by summing source terms for the appropriate quarters. Additional input to GASPAR includes the following station-supplied data:

- 0 to 50 mile population distribution

- 0 to 50 mile meat, milk, and vegetable distributions

- Absolute humidity at Cooper Nuclear Station (14.61 g/m3)

- The fraction of the year that the vegetables are grown (0.5)

- The fraction of the daily feed intake derived from pasture for milk and meat animals (0.5)

Other values used for input to GASPAR are default values from Regulatory Guide 1.109, Rev. 1.

I. Summary In 2008, the Cooper Nuclear Station (CNS) of the Nebraska Public Power District (NPPD) Nebraska Public Power District instituted a comprehensive program to evaluate the impact of station operations on groundwater in the vicinity of CNS. This report covers groundwater samples, collected outside of the Licensee required Off-Site Dose Assessment Manual (ODAM) requirements, both on and off station property in 2009.

During that time period, 308 analyses were performed on 44 samples from 11 locations.

In assessing all the data gathered for this report, it *as concluded that the operation of CNS had no adverse radiological impact on the environment, and there are no known active releases into the groundwater or surface water at Nebraska Public Power District.

Gross alpha was detected in five locations. The concentrations ranged from 2.82 + 1.85 pCi/L to 8.10 +/- 3.30 pCi/L.

Tritium was not detected in any of the groundwater samples at concentrations greater than the United States Environmental Protection Agency (USEPA) drinking water standard (and the Nuclear Regulatory Commission Reporting Limit) of 20,000 pCi/L. The tritium concentrations ranged from 238 +/- 121 pCi/L to 1170 + 181 pCi/L.

Strontium-89 and strontium-90 were not detected at concentrations greater than the Lower Limit of Detection (LLD) as specified in NUREG-1302 in any of the groundwater samples.

Iron-55 was not detected in any of the groundwater samples.

Nickel-63 was not detected in any of the groundwater samples.

Gamma-emitting radionuclides associated with licensed plant operations were not detected at concentrations greater than their respective Lower Limits of Detection (LLDs) as specified in NUREG-1302 in any of the groundwater samples. In the case of tritium, CNS specified that the independent laboratory achieve a lower limit of detection 10 times lower than that required by the United States Environmental Protection Agency (USEPA) regulation.

II. Characteristics of Tritium (H-3)

Tritium (chemical symbol H-3) is a radioactive isotope of hydrogen. The most common form of tritium is tritium oxide, which is also called "tritiated water." The chemical properties of tritium are essentially those of ordinary hydrogen.

Tritiated water behaves the same as ordinary water in both the environment and the body.

Tritium can be taken into the body by drinking water, breathing air, eating food, or absorption through skin. Once tritium enters the body, it disperses quickly and is uniformly distributed throughout the body. Tritium is excreted primarily through urine with a clearance rate characterized by an effective biological half-life of about 14 days.

Within one month or so after ingestion, essentially all tritium is cleared. Organically bound tritium (tritium that is incorporated in organic compounds) can remain in the body for a longer period.

Tritium is produced naturally in the upper atmosphere when cosmic rays strike air molecules. Tritium is also produced during nuclear weapons explosions, as a by-product in reactors producing electricity, and in special production reactors, where the isotopes lithium-7 and/or boron-10 are activated to produce tritium. Like normal water, tritiated water is colorless and odorless. Tritiated water behaves chemically and physically like non-tritiated water in the subsurface, and therefore tritiated water will travel at the same velocity as the average groundwater velocity.

Tritium has a half-life of approximately 12.3 years. It decays spontaneously to helium-3 (3He). This radioactive decay releases a beta particle (low-energy electron). The radioactive decay of tritium is the source of the health risk from exposure to tritium.

Tritium is one of the least dangerous radionuclides because it emits very weak beta radiation and leaves the body relatively quickly. Since tritium is almost always found as water, it goes directly into soft tissues and organs. The associated dose to these tissues is generally uniform and is dependent on the water content of the specific tissue.

III. Introduction 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 an 805-megawatt (net electrical) boiling water reactor. Initial criticality was attained on February 21, 1974.

This report covers those analyses performed by Teledyne Brown Engineering (TBE) on samples collected in 2009.

A. Objectives of the Radiological Groundwater Protection Program (RGPP)

The long-term objectives of the RGPP are as follows:

1. Identify suitable locations to monitor and evaluate potential impacts from station operations before significant radiological impact to the environment and potential drinking water sources.

2. Understand the local hydrogeologic regime in the vicinity of the station and maintain up-to-date knowledge of flow patterns on the surface and shallow subsurface.

3. Perform routine water sampling and radiological analysis of water from selected locations.

4. Report new leaks, spills, or other detections with potential radiological significance to stakeholders in a timely manner.

5. Regularly assess analytical results to identify adverse trends.

6. Take necessary corrective actions to protect groundwater resources.

B. Implementation of the Objectives The objectives identified have been implemented at CNS as discussed below:

1. Cooper Nuclear Station will continue to perform routine sampling and radiological analysis of water from selected locations.

2. Cooper Nuclear Station has implemented new procedures to identify and report new leaks, spills, or other detections with potential radiological significance in a timely manner.

3. Cooper Nuclear Station staff assesses analytical results on an ongoing basis to identify adverse trends.

C. Program Description

1. Sample Collection Sample locations can be found in Appendix A, Table A-I and Map A-I.

Groundwater Samples of water are collected, managed, transported and analyzed in 7 H-8

accordance with approved procedures following regulatory methods.

Sample locations, sample collection frequencies and analytical frequencies are controlled in accordance with approved station procedures. Contractor and/or station personnel are trained in the collection, preservation management, and shipment of samples, as well as in documentation of sampling events. Analytical laboratories are subject to internal quality assurance programs, inter-laboratory cross-check programs, as well as nuclear industry audits. Station personnel review and evaluate all analytical data deliverables after initial review by the contractor.

Analytical data results are reviewed by both station personnel for adverse trends or changes to hydrogeologic conditions.

IV Program Description A. Sample Analysis This section describes the general analytical methodologies used by TBE to analyze the environmental samples for radioactivity for the CNS RGPP in 2009.

In order to achieve the stated objectives, the current program includes the following analyses:

1. Concentrations of gross alpha in groundwater.

2. Concentrations of tritium in groundwater.

3. Concentrations of strontium-89 and strontium-90 in groundwater.

4. Concentrations of iron-55 in groundwater.

5. Concentration of nickel-63 in groundwater.

6. Concentrations of gamma emitters in groundwater.

B. Data Interpretation The radiological data collected prior to CNS becoming operational were used as a baseline with which these operational data were compared. For the purpose of this report, CNS was considered operational at initial criticality. Several factors were important in the interpretation of the data:

8 S H-9

1. Lower Limit of Detection and Minimum Detectable Concentration The lower limit of detection (LLD) is specified by federal regulation as a minimum sensitivity value that must be achieved routinely by the analytical parameter.

2. Laboratory Measurements Uncertainty The estimated uncertainty in measurement of tritium in environmental samples is frequently on the order of 50% of the measurement value.

Statistically, the exact value of a measurement is expressed as a range with a stated level of confidence. The convention is to report results with a 95% level of confidence. The uncertainty comes from calibration standards, sample volume or weight measurements, sampling uncertainty and other factors. CNS reports the uncertainty of a measurement created by statistical process (counting error). Each result has two values calculated. CNS reports the result with plus or minus (+/-) the estimated sample standard deviation.

Analytical uncertainties are reported at the 95% confidence level in this

'report for reporting consistency with the REMP.

Gamma spectroscopy results for each type of sample were grouped as follows:

For groundwater 18 nuclides, Be-7, K-40, Mn-54, Co-58, Fe-59, Co-60, Zn-65, Zr-95, Ru-103, Ru-106, 1-131, Cs-134, Cs-137, Ba-140, Ce-141, Ce-144, Ra-226 and Th-228 were reported.

V. Results and Discussion A. Groundwater Results Gross Alpha Samples from 11 locations were analyzed for gross alpha (Table B-I, Appendix B). Gross alpha was detected at five locations. The concentrations ranged from 2.82 to 8.10 pCi/L.

Tritium Samples from 11 locations were analyzed for tritium activity (Table B-l, Appendix B). Tritium was detected at two locations. Tritium values 9 H-10

ranged from 238 to 1170 pCi/L. All values were below the CNS ODAM LLD of 2000 pCi/liter.

Strontium Samples from 11 locations were analyzed for strontium-89 and strontium-90 (Table B-i, Appendix B). Strontium-89 and strontium-90 were not detected at concentrations greater than the LLD.

Iron-55 Samples from 11 locations were analyzed for iron-55 (Table B-i, Appendix A). Iron-55 was not detected at concentrations greater than the LLD.

Nickel-63 Samples from 11 locations were analyzed for nickel-63 (Table B-i, Appendix B). Nickel-63 was not detected at concentrations greater than the LLD.

Gamma Emitters Naturally occurring potassium-40 was detected in five of 44 samples. The concentrations ranged from 35.4 to 88.7 pCi/liter. Thorium-228 was detected in four of 44 samples. The concentrations ranged from 4.09 to 9.52 pCi/liter. Ra-226 was detected on one sample at a concentration of 59.8 pCiL. No other gamma emitting nuclides were detected (Table B-i, Appendix B).

I Introduction This report contains a complete tabulation of data for non-ODAM required Sampling Stations collected during the period January through December 2009 for the Cooper Nuclear Station (CNS) of the Nebraska Public Power District (NPPD) by Teledyne Brown Engineering - Environmental Services.

In assessing all the data gathered for this report, it was concluded that the operation of CNS had no adverse radiological impact on the environment, and there are no known active releases into the groundwater or surface water at Nebraska Public Power District.

II. Summary and Discussion of 2009 Analytical Results Data from the radiological analyses of environmental media collected during 2009 for non-ODAM required stations are tabulated and discussed below.

Radiological analyses of environmental media characteristically approach and frequently fall below the detection limits of state-of-the-art measurement methods. The "less than" values in the data tables were calculated from each specific analysis and are dependent on sample size, detector efficiency, length of counting time, chemical yield (when appropriate) and the radioactive decay factor from time of counting to time of collection.

Teledyne Brown Engineering's analytical methods meet or are below the Lower Limit of Detection (LLD) requirements given in Table 2 of the USNRC Branch Technical Position, Radiological Monitoring Acceptable Program (November 1979, Revision 1).

Appendix C contains a discussion of the LLD formulas.

The following is a discussion and summary of the results of the environmental measurements taken during the 2009 reporting period:

A. AirborneParticulates Gross beta activity was observed in 52 of the 52 samples collected during 2009. The average concentration was 0.023 pCi/m 3 with a range of 0.009 to 0.052 pCi/m 3. The results of the gross beta activities are presented in Table B-1. The gross beta activities for 2009 were comparable to levels measured in the previous several years. Prior to that period the gross beta activities were higher due to atmospheric nuclear weapons testing performed in other countries. The preoperational period of 1971 through 1974 averaged 0.098 pCi/m 3 gross beta.

Air particulate filters were collected weekly and composited by locations on a quarterly basis. They were analyzed by gamma ray spectroscopy. The results are presented in Table B-2. Beryllium-7, which is produced continuously in the upper atmosphere by cosmic radiation, was measured in three of four composite samples. The location had an average Be-7 concentration of 0.160 pCi/mi3 with a range of 0.121 to 0.213 pCi/m 3.

During the preoperational period, beryllium-7 was measured at comparable levels. All other gamma emitters were below the detection limits.

B. AirborneIodine Charcoal cartridges used to collect airborne iodine were collected weekly and analyzed by gamma spectrometry for iodine- 131. The results are presented in Table B-1. All results were below the required lower limit of detection.

5 1-6

C. Thermoluminescent Dosimeters Thermoluminescent dosimeters (TLDs) determine environmental radiation doses and the results are presented in Table B-3. Ambient radiation was monitored at 26 non-ODAM required locations and collected quarterly. The quarterly average for the locations was 23.0 millirem/quarter and a range from 18.9 to 33.4 millirem/quarter. The preoperational period of 1971 through 1974 averaged 7.0 millirem/quarter. The data from year to year is in good agreement and indicates no adverse changes in radiation exposure to the population near the Cooper Nuclear Station.
