SECTION I. INTRODUCTION 7

I. INTRODUCTION This report contains a complete tabulation of data collected during the period January through December 2011, 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 for the analyses for Cooper Nuclear Station.

The United States Nuclear Regulatory Commission (USNRC) regulations (IOCFR50.34a) 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 and Nuclear Incidents 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.

On March 11, 2011 an earthquake off the Japanese islands produced a massive tsunami which caused a nuclear incident at four of the six Fukushima Daiichi reactors. In planning for the potential radioactive plume reaching the United States, CNS increased the sampling frequency, added new air sampling equipment to already existing REMP stations (designated with an N, i.e. N-I, N-2, etc.), and added additional analyses of select media from pathways that were expected to be the most sensitive to any increase in ambient radiation levels. Iodine-131 by chemical separation and gamma spectroscopy analyses were performed on air particulate, air iodine and groundwater samples.

The resulting radioactive plume was first detected in the environs of CNS on week ending March 29, 2011. The final date of positive detection was on week ending April 13, 2011. The radionuclide identified was Iodine-131. Maximum activity levels found by media were 0.311 pCi/m 3 for air iodine. Samples collected were compared to offsite control locations to verify that these positive detections were not attributable to licensed activities. All other plant produced radionuclides were below required LLDs.

Iodine-131 detected at ODAM locations are footnoted as being attributed to the Fukushima incident in the Section VII tables and are not included in the Radiological Environmental Monitoring Program Summary Table, 2011. Data results pertaining to the Fukushima incident are discussed in Appendix K.

The radioactive half-life of 1-131 is about 8 days. This short half-life allowed the affects of this radioactive plume to subside over about 3 weeks. As of April 13, 2011 no further impact from the Fukushima Daiichi incident was evident.

B. Monitoring Program 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 9

equal to or lower than pre-determined limits of detection. In addition the source of the environmental radiation must be established. Sources 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.

(6) Fallout from the Fukushima Daiichi incident.

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.

SECTION III. SAMPLING AND ANALYSES PROGRAM 13

Il. SAMPLING AND ANALYSES PROGRAM The 2011 sampling and analyses program is described in Table 1. Teledyne Brown Engineering - Environmental Services has a comprehensive quality assurance/quality control program designed to assure the reliability of data obtained. The results for the 2011 Interlaboratory Comparison Program conducted by Analytics, Inc.,

the Department of Energy's (DOE) Mixed Analyte Performance Evaluation Program (MAPEP) and Environmental Resource Associates (ERA) are contained in Appendix B.

Sampling locations are indicated in the map labeled Figure 1. The sample types collected at each location and the approximate distance and direction from the reactor elevated release point are specified.

The annual land use census for 2011 is described in Appendix A. There were no milk animals found within three miles of CNS in 2011 and no evidence of potable water use from the river. The nearest garden to CNS is in sector L, 1.3 miles from CNS. From year to year there is a slight variation in the number if gardens tended. The nearest resident to CNS is in sector Q, 0.9 miles from CNS.

All of the required 2011 environmental monitoring, including sampling and analyses, were conducted as specified in Table D4.1-1 of the CNS Offsite Dose Assessment Manual (ODAM), except as noted in Appendix E, REMP Sampling and Analytical Exceptions table.

SUMMARY

AND DISCUSSION OF 2011 ANALYTICAL RESULTS 18

SUMMARY

AND DISCUSSION OF 2011 ANALYTICAL RESULTS Data from the radiological analyses of environmental media collected during 2011 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.

Record snowfall (an estimated 212% of normal snowpack) in the Rocky Mountains of Montana and Wyoming along with near record spring rainfall (almost a year's worth of rain) in central and eastern Montana in the second half of May 2011, resulted in six major dams along the Missouri River releasing record amounts of water to prevent overflow. This led to flooding of several towns and cities along the river from Montana to Missouri.

At Cooper Nuclear Station, Nebraska Public Power District's (NPPD) nuclear plant near Brownville, a "Notification of Unusual Event" was issued on June 19 due to the flooding. In preparation for the flood more than 5,000 short tons (4,500,000 kg) of sand and a number of Hesco barriers were brought in to protect the facility. The plant is 13 feet (4.0 m) above natural grade. On June 19, the river was reported 11.5 feet (3.5 m) above flood stage at Brownville. The Cooper plant sits at 903 feet (275 m) above sea level. The river hit 900.56 feet (274.49 m) on June 19, 2011 before dropping slightly to 900.4 feet (274.4 m) on June 20, 2011. At 9:47 a.m., July 12, 2011 the plant ended its emergency status because the river had dropped to 895.8 feet-3 feet lower than the emergency status level.

On June 23, the main levee 3 miles (4.8 km) north of Brownville Bridge breached, prompting an evacuation in Atchison County, MO.

The flooding of the Missouri River prevented collection of air particulate, air 19

iodine, fish, river water and TLD samples from the environs of Cooper Nuclear Station.

Appendix E, REMP Sampling and Analytical Exceptions table, page E-3, lists the locations with missing data.

The following is a discussion and summary of the results of the environmental measurements taken during the 2011 reporting period:

20

A. Airborne Particulates Gross beta activity was observed in 383 of the 387 indicator samples collected during 2011. The average concentration was 0.022 pCi/m 3 with a range of 0.005 to 0.054 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 2011 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 30 of 30 composite3 samples. The indicator locations had an average concentration of 0.141 pCi/mi with a range of 0.081 to 0.207 pCi/m 3 . During the preoperational period, beryllium-7 was measured at comparable levels. Naturally occurring thorium-228 was detected in one of 30 composite samples. The indicator location had a concentration of 0.004 pCi/mr3. 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. Due to flooding of the Missouri River, fish samples were not collected during 2011. The preoperational period of 1971 through 1974 averaged 2400 pCi/kg potassium-40.

D. Milk - Nearest Producer 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. All iodine-131 results were below the required lower limit of detection. Naturally occurring potassium-40 was measured in all samples with an average concentration of 1192 pCi/liter and a range of 939 to 1360 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 2011 and results are presented in Table VII-5 and Trending Graph 5. Station 103 was sampled quarterly in 2011. The milk samples were analyzed by gamma ray spectroscopy and for low-level iodine-131 by radiochemical separation. All iodine-131 results were below the required lower limit of detection. Naturally occurring potassium-40 was detected in all four samples analyzed with an average concentration of 1488 pCi/liter and a range of 1250 to 1740 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 21.7 millirem/quarter and a range from 14.7 to 62.4 millirem/quarter. The control station 44, which is located 10.3 miles, 270 degrees, had an average of 22.8 millirem/quarter and a range from 19.2 to 25.6 millirem/quarter. The highest station was Station 90 with an average of 28.7 millirem/quarter and a range from 16.4 to 62.4 millirem/quarter. The preoperational period of 1971 through 1974 averaged 37.0 millirem/quarter; which is the preoperational four year average. Current year TLD averages deviate from the preoperational averages due to instrument variations from previous vendors.

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.

[----- Cs-134 --*-Cs-137 -.- Cs-134 ODAM LLD Cs-137 ODAM LLD The low Cs-I137 value reported in July 2001 was due to the wrong aliquot being entered for the gamma analysis resulted in an invalid analysis and is not reported Due to delay in sample receipt, the 1-131 had decayed away, resulting in an invalid analysis for May 2002 and is not reported.

Milk samples were collected in lieu of broadleaf vegetation samples in 2004 and 2005.

Due to delay in counting sample, the 1-131 had decayed away, resulting in an invalid analysis for June 2006 and is not reported. The 1-131 by chemical separation met required 1-131 LLD.

Trending Graph 9 represents minimum detectable concentration (MDC) results. 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.

Broadleaf vegetation samples were not available for collection in 2011.

SECTION V. CONCLUSIONS 32

V. CONCLUSIONS The results of the 2011 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. Concentrations of Iodine-1I31 are credibly attributed to the trans-Pacific transport of airborne releases from the March 11, 2011 Fukushima incident were also observed in sample media and have been noted in the tables, as appropriate, and is not related to the operations of Cooper Nuclear Station.

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 2011 LAND USE CENSUS A-1

2011 LAND USE CENSUS Conducted July 12-13, 2011 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 12-13, 2011, 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 Engineerin2 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 2011 Interlaboratory Comparison Program includes all contractually required matrices and analyses we supply to customers.

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.

TWO SIGMA ERROR (pCi/m3) 2((S/T ) + (B/t 2 ))l/ 2 /(2.22 V E) 1/2 LLD (pCi/rn3) = 4.66(B )/(2.22 V E t) where:

C-3

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 I liter of sample is used and that 0.5 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.

C-4

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) //(2.22 V E) 1/2 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:

RESULT = (N/At-B)/(2.22 E V Y DF) 1/2 TWO SIGMA ERROR = 2((N/At+B)/At) /(2.22 E V Y DF) 1/2 LLD = 4.66(B/At) /(2.22 E V Y DF) where: N = total counts from sample (counts)

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-0.0061 M)/(exp-0.0061 Ms)

Es = efficiency of the counter determined from an 1-131 standard mount Ms = mass of Pdl 2 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) 1/2 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 =-12.8d) 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 Mirion Technologies. Mirion Technologies 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 O7 -Cu Thin plastic 2 CaSO 4 -Tm Lead 3 CaSO 4 -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 Mirion 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 Mirion Technologies 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 + E3, + E4,) _ (E3a +__+_E4,a.)

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-,At 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.

SUMMARY

OF DOSES TO A MEMBER OF THE PUBLIC OFFSITE F-1

LIQUID EFFLUENT DOSE CALCULATIONS Doses to the maximum individual and 0 to 50 - mile population resulting from the release of radioactive material in liquid effluents from Cooper Nuclear Station were calculated using the LADTAP II computer program. The LADTAP II program implements the radiological dose models of Regulatory Guide 1.109 for determining the radiation exposure to man from three principal exposure pathways in the aquatic environment -- potable water, aquatic foods, and recreational water use. Doses to both the maximum individual and 0 to 50 mile population are calculated as a function of age group and pathway for significant body organs, and are presented in Tables 1 - 6.

Assumptions and data sources used for input to the LADTAP II code are described in a separate section of this appendix (see page F-67).

GASEOUS EFFLUENT DOSE CALCULATIONS (EXCEPT CARBON-14)

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-67).

CARBON-14 GASEOUS EFFLUENT DOSE CALCULATIONS Doses to the maximum individual resulting from the release of Carbon-14 in gaseous effluents from the Cooper Nuclear Station (CNS) were calculated using the GASPAR computer code.

Four pathways were selected for individual dose calculations: the nearest site boundary for inhalation, nearest garden for vegetation ingestion, nearest animal for meat ingestion, and the nearest milk animal (cow). Based on the 2011 Land Use Census, there are no meat or milk animals identified within 5 miles of CNS. However, CNS maintains a virtual cow receptor at 3.5 miles north-northwest of the plant and conservatively includes this receptor in dose calculations.

Use of a normalized Carbon-14 source term and scaling factors based on the annual thermal gigawatts (GWT) power generation were utilized to determine the quantity of Carbon-14 in the CNS gaseous effluent discharge for 2011. Specifically, the Boiling Water Reactor proxy production rate of 5.1 curies Carbon- 14 per GWT generation using the methodology described in EPRI, 20110 was the basis for the CNS total calculated emissions of 10.4 curies of Carbon-14 in 2011.

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 are calculated as a function of age group and pathway for significant body organs.

Tables 15 through 21 present maximum individual doses. Note that the inhalation pathway was calculated at the closest site boundary receptor and was negligible for Carbon-14 and is not included in the tables. In addition, the doses presented were conservatively calculated based on the annual site X/Qs. These X/Qs result in doses approximately 20% higher than those calculated with the X/Qs based on growing season meteorology.

Additional assumptions and data used for input to the GASPAR code are described in a separate section of this appendix (see page F-67).

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 22. 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, as described in Appendix B. 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/m 3)

- 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.

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 2011.

During that time period, 440 analyses were performed on 83 samples from 15 locations.

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.

Gross alpha was not detected in any of the groundwater samples.

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 237 +/- 121 pCi/L to 6,540 +/- 703 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 functions 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.

111. INTRODUCTION Cooper Nuclear Station is located in Nemaha County in the southeast comner 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.

This report covers those analyses performed by Teledyne Brown Engineering (TBE) on samples collected in 2011.

III. INTRODUCTION (cont)

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

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

I. 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 10 H-II

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.

SECTION IV. PROGRAM DESCRIPTION 12 H-13

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 2011.

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:

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 13 H-14

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.

I. INTRODUCTION This report contains a complete tabulation of data for non-ODAM required Sampling Stations collected during the period January through December 2011 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.

SUMMARY

6 1-7

II. Summary Data from the radiological analyses of environmental media collected during 2011 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 meets 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).

The following is a discussion and summary of the results of the environmental measurements taken during the 2011 reporting period:

Il. Results and Discussion of 2011 Analytical Results A. Airborne Particulates Gross beta activity was observed in 52 of the 52 samples collected during 2011.

The average concentration was 0.022 pCi/mr3 with a range of 0.008 to 0.052 pCi/m 3. The results of the gross beta activities are presented in Table B-1. The gross beta activities for 2011 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. Iodine-13 lwas detected in one sample at a concentration 0.068 pCi/mr3 in the 2 nd quarter 2011 composite. The activity is attributed to the Fukushima accident as described in the annual REMP report. All other gamma emitters were below the detection limits.

B. Airborne Iodine 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. Iodine-131 was detected in two samples collected week end 03/29/11 and 04/05/11 with concentrations of 0.093 and 0.113 pCi/m 3A, respectively. The activity is attributed to the Fukushima accident as described in the annual REMP report. All other results were below the required lower limit of detection.

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 22.4 millirem/quarter and a range from 14.4 to 51.3 millirem/quarter. The preoperational period of 1971 through 1974 averaged 37.0 millirem/quarter. Current year TLD averages deviate from the preoperational averages due to instrument variations from previous vendors.

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.

D. ErrataData There was no errata data for 2011.

SUMMARY

On March 11, 2011 an earthquake off the Japanese islands produced a massive tsunami that caused a nuclear incident at four of the six Fukushima Daiichi reactors. In planning for the potential radioactive plume reaching the United States, CNS increased the sampling frequency, added new air sampling equipment to already existing REMP stations (designated with an N, i.e.

N-i, N-2, etc.), and added additional analyses of select media from pathways that were expected to be the most sensitive to any increase in ambient radiation levels. Low level 1-131 analyses and gamma spectroscopy analyses were performed on air particulates, air iodine and groundwater.

The resulting radioactive plume was first detected in the environs of CNS on week ending March 29, 2011. The final date of positive detection was on week ending April 13, 2011.

The radionuclide identified was Iodine- 131. The maximum activity level found by media was 0.311 pCi/m3 in air iodine. Samples collected were compared to offsite control locations to verify that these positive detections were not attributable to licensed activities. All other radionuclides analyzed for were below MDL.

The radioactive half-life of 1-131 is about 8 days. This short half-life allowed the affects of this radioactive plume to subside over about 3 weeks.

HI. Promrm Description A. Sample Analysis This section describes the general analytical methodologies used by TBE to analyze the environmental samples for radioactivity for the CNS REMP during March and April in 2011, as a result of the Fukushima incident.

In order to detect a potential radioactive plume, the following analyses were monitored:

1. Concentrations of iodine- 131 in air iodine samples.

2. Concentrations of gamma emitting isotopes in air particulate samples.

3. Concentrations of iodine-131 by chemical separation and gamma emitting isotopes in ground water samples.

B. Program Description

1. Air Particulate and Air Iodine Sample Collection

a. Routine REMP Samples In addition to gross beta, TBE was requested to run a gamma analysis on the weekly air particulate samples.

b. New Air Sampling Locations New air sampling locations were established at the ODAM required locations 2 and 8 and non-ODAM required location 111. The new air sampling locations were identified as N-2, N-8 and N-Ill. Air particulate and air iodine samples were collected every two days (every 3 days for the weekend). Gross beta, 1-131 by chemical separation and gamma spectroscopy were performed on the samples.

c. New Groundwater Sampling Locations New groundwater sampling locations were established at the ODAM required locations II and 47. The new ground water sampling locations were identified at N- 11 and N-47. Five grab samples were collected from 03/28/11 to 05/02/11. Gamma spectroscopy was performed on the samples.

Ill. Results and Discussion A. Routine REMP Samples

1. Air Iodine Weekly samples from 10 air iodine locations were analyzed for iodine- 131 activity (Fukushima Table A-1, Appendix A). Iodine- 131 was detected at all 10 air sampling stations from week end March 29 to week end April 13, 2011. The iodine-131 values ranged from 0.047 to 0.137 pCi/m3 .

2. Air Particulate Gamma Spectroscopy Seventy samples from 10 locations were analyzed for gamma emitting radionuclides from week end March 22 to week end May 3, 2011.

(Fukushima Table A-2, Appendix A). Naturally occurring beryllium-7, potassium-40 and thorium-228 were detected in some samples.

Iodine-131 by gamma spectroscopy was detected at six air sampling stations (stations 2, 6, 7, 9, 10 and 11) from week end March 29 to week end April 5, 2011. The iodine-131 values ranged from 0.040 to 0.109 pCi/m 3. All other gamma emitters were below the LLD.

B. New Air Sampling Locations

1. Air Iodine Nineteen samples from three locations were analyzed for iodine-131 activity (Fukushima Table A-3, Appendix A). Iodine-I131 was detected at all three air sampling stations from week end March 23 to week end April 6, 2011. The iodine-131 values ranged from 0.075 to 0.311 pCi/m3 .

2. Air Particulate Gamma Spectroscopy Fifty-seven samples from three locations were analyzed for gamma emitting radionuclides from week end March 18 to week end May 2, 2011. (Fukushima Table A-4, Appendix A). Naturally occurring beryllium-7, potassium-40 and thorium-228 were detected in some samples. Iodine-131 by gamma spectroscopy was detected in one sample from each location on week end March 30, 2011. The iodine-131 values ranged from 0.109 to 0.146 pCi/mi3. All other gamma emitters were below the LLD.

3. Ground Water Iodine by Chemical Separation Ten grab samples from two locations were analyzed for iodine by 9

chemical separation from March 28 to May 2, 2011. Iodine- 131 was not detected in any of the samples.

4. Ground Water Gamma Spectroscopy Ten grab samples from two locations were analyzed for gamma emitting radionuclides from March 28 to May 2, 2011. Naturally occurring thorium-228 was detected in one sample. Iodine-131 by gamma spectroscopy was not detected in any of the samples. All other gamma emitters were below the LLD.
